You had requested that the City provide copies of documents related to the State Environmental Policy Act (SEPA) environmental review of the project. Upon our telephone conversation, we determined that the documents were sent to the Fisheries Department within your organization. I wanted to inform you that the City has decided to add Melissa Calvert as a second Muckleshoot contact to send the SEPA documents to. With regard to the project site, I have informed the City's Construction Project Manager (Tracy Coleman) of your concerns regarding the location of this project.

OLD BUSINESS Council President Keolker-Wheeler presented a report regarding the tracking of Committee of the Whole restrictive covenants required through the permit process. Until a few years Development Services: ago, covenants restricting the development of property were difficult to track. Tracking Restrictive Staff generally did not know if any restrictive covenants affected a property Covenants unless a title report was provided. Title reports are expensive for applicants and are only required for certain types of land use applications. At the end of 1999, staff completed a project cataloging and mapping all of the restrictive covenants required by the City. Staff can now research the covenants by consulting a map to identify affected properties. A corresponding database provides the recording number of the restrictive covenant,a legal description of the subject property, and a summary of the requirement of the covenants. In addition,the Permits Plus permit tracking system is utilized to document conditions of permit approval, including covenants. These conditions can be researched by project name, address or parcel identification number. Another tool developed by staff to track project conditions is a matrix summarizing the required conditions. Copies of this matrix are distributed to the contractors and inspectors at pre-construction meetings. The Committee recommended no further action be taken at this time.

February 25,2003 OFFICE OF THE HEARING EXAMINER CITY OF RENTON REPORT AND RECOMMENDATION APPLICANT: Dennis Culp City of Renton 1055 South Grady Way Renton, WA 98055 Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF LOCATION: 1715 Maple Valley Highway SUMMARY OF REQUEST: The construction of an aquatic center featuring a leisure pool, lap pool,changing rooms and concession areas. SUMMARY OF ACTION: Development Services Recommendation: Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on February 11, 2003. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area;the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the February 18, 2003 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,February 18, 2003,at 9:04 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Neighborhood Detail Map application,proof of posting,proof of publication and other documentation pertinent to this request. Exhibit No.3: Overall Site Plan Exhibit No.4: Aquatic Center Site Plan Exhibit No.5: Building Elevations Exhibit No. 6: Building Floor Plan Exhibit No.7: Utilities &Drainage Control Plan Exhibit No. 8: Landscape Plan Exhibit No.9: Zoning Map The hearing opened with a presentation of the staff report by Jason Jordan,Associate Planner, Development Services, City of Renton, 1055 S Grady Way,Renton, Washington 98055. Mr. Jordan explained that this site S y Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 2 plan review would be a recommendation to Council rather then a Hearing Examiner decision due to it being located in the Center Office Residential (COR)zone. The new City operated Aquatic Center would be located within the existing Cedar River Park site. The proposed Aquatic Center is to be constructed in the northeast corner of the site closest to Maple Valley Highway. The Cedar River is located south and east of the subject site. The Community Center Building and Carco Theatre are also located on this site. There is a large parking lot in the central portion of the property. The parks maintenance buildings are located east and south of the proposed aquatic center site. Interstate 405 and Houser Way are immediately west of the site. The Maple Valley Highway is located north and east of the site. The Stoneway concrete plant is east of the site. The Aquatic Center would include a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Activities with this proposal would include recreational uses, swim lessons,therapeutic uses and occasional swim meets. Construction is planned to begin in April of this year and be substantially completed by December 2003. The City expects to operate the pool from approximately Memorial Day to Labor Day weather permitting. Typical hours of operation will be from dawn to dusk. Access to the site is proposed from two locations. The primary access is proposed from Maple Valley Highway where there is a full-signalized intersection. The secondary access,which is limited to a right in,right out, is from Houser Way North. The Environmental Review Committee(ERC)issued a Determination of Non-Significance-Mitigated(DNS-M) with six mitigation measures for the project. There were no appeals filed. Five of the mitigation measures were standard erosion control mitigation measures. The last mitigation measure was for a Fire Impact Fee. Mr. Jordan reviewed several policies from the Comprehensive Plan and how they are applicable to the project. Staff believes that the Aquatic Center is a nice addition to the current recreational uses within the site. The site is already recreational and this would only be augmenting that use in a high quality manner. The applicant is not proposing any additional parking and they have done a fairly thorough investigation of getting pedestrian and vehicular access off the roads to the parking areas and to the aquatic center. In regard to conformance with land use regulations,the COR zone allows Aquatic Center uses as primary permitted uses in this zone. The Development Standards with regard to lot coverage allow up to 65 percent coverage in the COR zone. This particular project only has lot coverage of 6.5 percent with the additional 6,500 square feet of building area. In regard to setbacks,the proposed aquatic center is located 100 feet from the Maple Valley Highway and 500 feet from the Cedar River. It is also located 480 feet from Houser Way and 160 feet from the Stoneway Concrete plant. The Aquatic Center has substantial setbacks that would mitigate any potential concerns from neighboring properties. The required landscaping is already in place as part of the development. The proposed Aquatic Center at 19 feet in height is well below the 125 feet maximum allowed in the COR zone. There are an existing 400 parking stalls at the site. Development code requires one stall per 100 square feet. The zoning code did not have a ratio for parking for swimming pools so staff used the community center type parking requirements for the aquatic center use. This would have required an additional 266 parking stalls for Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 3 the Aquatic Center use; however,the applicant put together a pretty solid argument indicating that the one per 100 square feet is too high for the Aquatic Center and the demand would be far less. Secondly,the Community Center,Carco Theater and the Renton Aquatic Center will have different peak hours of operation and the 400 stalls currently available would be adequate. Staff reviewed this information and administration issued a parking modification for the project. The proposal is located within an existing park site and has already been utilized as recreation. Staff feels that because the existing uses are recreational there should be no impacts to surrounding properties. Construction activities would result in short term noise, dust and traffic impacts; however,these will be limited to the construction phase and would be subject to a construction mitigation plan. A geotechnical report was submitted for the project. The report indicated that the site is appropriate for this type of use. The ERC did mitigate erosion for the site with the primary emphasis on no impacts to the Cedar River. The ERC mitigation measure should minimize any impacts of the site plan to the site. In regard to questioning from the Examiner, Mr. Jordan stated that after construction the site would be fenced with chain link fence and separated from the rest of the park area for safety reasons. The site is located within the Aquifer Protection Area(APA)zone. There will be some typical pool treatment chemicals on-site; however,they are below the maximum allowed for the APA zone. Staff expects that the Aquatic Center would increase the property values in the vicinity of the site. A traffic study was not required for this project. The project is not providing any additional parking but what the applicant has done is propose some extensive striping. There is already a paved walkway from the parking area next to the Maple Valley Highway that leads right past the site and continues on to the other buildings. With respect to parking in the main parking lot the applicant has put together a fairly good striping plan to allow for safe vehicle and pedestrian movement. The Aquatic Center is largely comprised of an open outdoor recreation area. There are some buildings but they are limited to 19 feet in height and located in the south corner and staff does not expect these buildings to impede any light or air circulation to the site. The buildings are not going to impact any of the other recreational opportunities in staff's opinion. The proposed development would not generate any harmful or unhealthy conditions. There would be noise impacts related to increased traffic and activity normally associated with recreational use. The Fire and Police Departments have indicated that they have sufficient resources to adequately accommodate the subject proposal provided the applicant pay the required Fire Mitigation Fee. Police did extensively review this project and do have concerns with safety and did have some suggestions for the construction phase of the project. Staff does not expect any neighborhood deterioration or blight and in fact expects the opposite. One of the criteria for the COR zone is that planning incorporates public and private open space to provide adequate areas for passive and active recreation. The site is entirely dedicated to recreation and has both active and passive recreation opportunities. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 4 The plan does provide view corridors to the shoreline areas. Staff does not expect any view corridors to be blocked. The project is setback over 500 feet from the Cedar River and the buildings are limited to 19 feet in height. There is still access to the Cedar River and the aquatic center will not be blocking access in any way. Mr. Jordan stated that there is additional review criteria for the COR zone and asked to clarify that typically for the COR zone there is a requirement that the site plan reviews go through a Level II Site Plan Review. Because this proposal did not go through a Level II Site Plan Review,the additional criteria must be reviewed. Staff does not believe that the two buildings would be an over concentration. The majority of the site is still predominantly open space. The applicant attempted to locate the pool in a more flat area so that less grading would have to occur and to be the least impact to the Cedar River. The lighting plan clearly shows that the lighting would be adequate for not only safety but also security and the lighting does not spill onto neighboring properties and certainly does not spill onto the Cedar River site. Staff believes that the applicant has put together a good site plan trying to tie in the natural areas and the open space areas. The structures proposed should not be an overburden to the existing site or be out of scale with the existing buildings on the site. The applicant will not be adding any additional impervious surface due to parking. The swimming pools will be tied into the sewer system. The swim decks are below the threshold for any type of water quality treatment. This is a very low impact development on the existing Cedar River site. Mr. Jordan added that there would be quite a few landscaped areas throughout the site. Staff recommends approval of the Renton Aquatic Center with no conditions. Boris Srdar,Northwest Architectural Company, 2201 6`h Avenue,#1405, Seattle, WA 98121 stated that this is the first facility of this type in the area. This is the third project of this kind that he has worked on. Experience tells them that about 50 percent of people who use the pools do not require parking. These types of facilities are very popular with children from the age of seven into their early teens. Most of the vehicles that do park are not single occupancy vehicles they are families with children. These facts combined with the occupancy rate of the facility means that less then half of the parking would go to the pool. In response to questioning from the Examiner regarding fencing,Mr. Srdar stated that given the priorities of the pool and the amenities to meet the base cost they have decided to use the chain link fencing rather then a wrought iron or something else. Mr. Jordan stated that he has checked with the applicant and the difficulty is the budget. They all agree that the wrought iron fence is much more aesthetically pleasing. One issue is that on the northwestern boundary of the pool the fence has to be a certain height because of the location of the ball fields. It may be possible to use wrought iron in the front of the aquatic center and have the rest be painted cyclone. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at 9:57 a.m. FINDINGS, CONCLUSIONS & RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 5 Findings: 1. The applicant,Dennis Culp, representing the City of Renton, filed a request for approval of a Site Plan for a new Aquatic Center. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee (ERC),the City's responsible official, issued a Declaration of Non- Significance- Mitigated (DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. There was no opposition from the public regarding the subject proposal. 6. The subject site is located 1715 Maple Valley Highway. The subject site is located on the south side of the highway immediately east of I-405 and just east of downtown Renton. The subject site is located in the northeast corner of the Cedar River Park complex that contains the Renton Community Center building and Carco Theater. The Cedar River is located south of the subject site. 7. The subject site is approximately 240 feet wide(Maple Valley Frontage)by 320 feet deep. The subject site is approximately 1.75 acres of the approximately 20-acre park site. 8. The subject site was annexed to the City with the adoption of Ordinance 1212 enacted in April 1945. 9. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of Center Office and Residential uses, but does not mandate such development without consideration of other policies of the Plan. 10. The subject site is zoned COR(Center Office Residential)a zoning designation applied to the subject site in June 1993. The COR zone permits parks and aquatic facilities. 11. The site east of the subject site,the concrete plant, is also zoned COR. The concrete plant is in the process of being decommissioned. There is a CA(Commercial Arterial)zone north of the site, across Maple Valley Highway. The Cedar River corridor and slopes on its south side are zoned RC (Resource Conservation). 12. The applicant proposes developing an Aquatic Center that contains four components. It will contain two outdoor pools including a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Complementing the two pools will be two buildings. These buildings will be approximately 6,500 square foot. There will be a changing rooms building that is approximately 32 feet wide by 160 feet long located in the southern portion of the site. The concessions area will be west of the changing area and will be approximately 48 feet square. Additional restrooms are located in the northeast corner of the site. 13. The leisure pool will be an elaborate facility with river area,wave area as well as a plunge area and other features. 14. The buildings will be one-story or approximately 19 feet tall. The COR zone permits buildings of 10 Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 6 stories or 125 feet tall. 15. There will be internal landscaping and the applicant will be taking advantage of existing landscaping that borders the existing park along its edges and frontage. 16. Staff analyzed the parking requirements for the use as well as the other uses that share the entire site. Currently there are 400 parking stalls located on the site serving the community center and the theater. The Community Center requires one stall per 100 square feet or 354 stalls and those are all provided. Carco Theater requires one stall per four fixed seats or 75 stalls and only 46 are provided. That's a deficit of 29 stalls. Code does not specifically address either pools or the more elaborate Aquatic Center. Staff compared the use to indoor or outdoor arenas or stadiums,which require one stall per 100 square feet like the Community Center itself. Staff calculated the Aquatic Center would require 266 stalls. The City's consultant reviewed the site,parking usage and similar uses and determined that the existing 400 stalls could reasonably serve the pool patrons. In addition,they anticipate that the theater and pool would have different demand hours. They expect a number of the patrons to be children who will be dropped off by parents or arrive by bicycle or in carpools with friends. The applicant noted that there is room on the grounds to provide additional parking if it is determined that their is insufficient parking. They would prefer saving the lawn areas if the parking were unnecessary. The applicant was granted an Administrative Parking Modification from the Code based on these various analyses. 17. The subject site will have two points of access. The main entry will be the signal-controlled intersection along the Maple Valley Highway. A second access is Houser Way via a tunnel under I-405. There will be a pullout near the entrance to the pool complex to allow drop-offs. Traffic will circulate around the east side of the new complex. 18. The new complex will be approximately 500 feet from the Cedar River. It will be setback approximately 480 feet from Houser Way and slightly less from I-405. The complex will be setback approximately 100 feet from the Maple Valley Highway and 160 feet from its eastern property line,the one shared with the cement plant. 19. The proposal requires 10 feet of landscaping along the Maple Valley Highway setback. The current landscaping will provide that setback. 20. The development of the swimming complex will result in the loss of lawn area replaced by the complex as well as a large Big Leaf Maple and nine Pin Oak trees. 21. The applicant proposed using chain link fencing to provide security around the subject site. The pool needs to be protected from illegal entry, particularly after hours. The applicant also noted that the pool and its patrons need to be protected from balls that might go astray from the nearby playfields. This office suggested that since the applicant considers this a gateway site for the City that more appropriate, aesthetically pleasing fencing such as wrought iron be used. The applicant indicated budget constraints might limit the ability to upgrade but might be able to use it along the Maple Valley frontage. 22. The aquatic center would replace the previous pool(Henry Moses Pool)at Liberty Park, which was demolished in 1999. 23. Construction of the complex is planned to begin in April 2003 and be substantially completed by December 2003. 24. The subject site is located in the Aquifer Protection Zone. No impacts on water quality are anticipated. The Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 7 storage of pool cleaning chemicals will follow standard practices. Conclusions: 1. The COR Zoning requires that an approval of a Site Plan be done by the City Council in this case. The COR zoning provides an extensive list of criteria to judge whether a proposal is appropriate in the zone as well as criteria for a Level I Site Plan as well as the normal criteria for Site Plan review. Some of the criteria overlap. 2. The site plan ordinance provides a number of specific criteria for reviewing a site plan. Those criteria are generally represented in part by the following enumeration: a. Conformance with the Comprehensive Plan; b. Conformance with the Building and Zoning Codes; c. Mitigation of impacts on surrounding properties and uses; d. Mitigation of the impacts of the proposal on the subject site itself; e. Conservation of property values; f. Provision for safe and efficient vehicle and pedestrian circulation; g. Provision of adequate light and air; h. Adequacy of public services to accommodate the proposed use; The proposed use satisfies these and other particulars of the ordinance. 3. The COR designation in the Comprehensive Plan suggests a coherent,high quality development that takes advantage of natural amenities. The proposed complex has been designed to provide a center for recreational opportunities in a unified campus. The pool complex has been designed to fit in with the general size and scale of the existing Recreation and Carco buildings. The low-rise nature is intended to keep the site open appearing and minimize impacts on the nearby Cedar River. 4. The one-story buildings,the setbacks and landscaping meet the limits provided by the Zoning Code. Detailed analysis of building code and fire code compliance will be determined when the building permit is submitted for review. The proposal has been granted a modification from parking standards based on an analysis of current parking demands as well as projected demands of the specific use. 5. The low-rise complex should have few if any impacts on surrounding properties. The complex is setback 160 feet from adjoining private property to the east. It will have a 100-foot setback from Maple Valley and is separated from the Cedar River by the other uses already established on the subject site. The use of chain link fencing for such a prominent site is unfortunate. If the City can fund an upgrade to make this gateway site more aesthetically pleasing it should do so while, clearly,not compromising the safety and security of patrons and the complex itself. 6. The open space at Cedar River Park will be diminished by the complex and some older, larger trees will need to be removed. The tradeoff is providing a quality swimming complex and new landscaping inside Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 8 the complex should soften its appearance especially when coupled with the existing landscaping. The construction will have clear short-term impacts including noise. The completed facility should have few impacts other than possibly noise associated with boisterous patrons. It will also probably generate additional visitation to the park during the summer months when the pool is operating. 7. The development should not adversely affect property values. It is planned as a high quality addition to the recreational amenities offered by the City. 8. The proposal will use the existing parking lot,which has proved adequate in both terms of efficiency and circulation. The pool complex will have a drop-off lane near its entrance to accommodate parents dropping off children to use the complex. The applicant will be restriping some of the parking and walking areas to accommodate pedestrians. 9. There will be adequate light and air in and around the one-story,open pool complex. 10. There is a full complement of public services to accommodate the facility. 11. The subject site is not located in the Urban Center Design Overlay area and is not subject to those special regulations. 12. Section 4-9-200E1k provides "Additional Special review Criteria for COR Zone Only:" and those in part include: 1. The plan is consistent with the Planned Action Ordinance, if applicable. 2. The plan creates a compact, urban development that includes a compatible mix of uses where appropriate. 3. The plan provides an overall urban design concept that is internally consistent and harmonious with development on adjacent sites. 4. The plan incorporates public and private open spaces to provide adequate area for passive and active recreation by the occupants/users of the site and/or protecting existing natural systems. 5. The plan provides view corridors to the shoreline areas where applicable. 6. Public access is provided to water and/or shoreline areas. 7. The plan provides distinctive focal points such as public area plazas, prominent architectural features or other items. 8. The plan assures adequate access to public streets. 9. The plan accommodates and promotes transit, pedestrian and other alternative modes of transportation. 13. The Aquatic Center proposal does not need a "Planned Action Ordinance." 14. The Aquatic Center is part of an urban park system. It contains, as a park should, open space. It is not an inherently compact urban proposal but concentrates many of Renton's community recreation facilities in Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 9 this one location. 15. The entire park concept has been developed to be homogeneous. While new elements such as the pool complex and the Community facility are or have been added,they are designed to blend with the existing park and facilities including the Carco Theater. Development around the site is sparse with I-405 and the Cedar River providing the most defined uses and the cement plant being phased out over the next few years. 16. The park provides its own open space unlike a private development proposal. The immediate pool complex provides the open water pools and two smaller buildings. The new complex should not affect the existing natural systems,which would be the Cedar River and the underlying drinking water aquifer. 17. The proposed aquatic complex should not severely impact any view corridors. Other buildings are already located between the Maple Valley Highway and the Cedar River. In addition, nothing about the new complex would detract from current access to the river and it's viewing and seating areas. 18. The aquatic center probably will become a new focal point for the Cedar River Park in itself. The entire recreational complex, though, serves this function. Hopefully, a more aesthetic fencing arrangement can further enhance the complex's prominent features. 19. The park's location at the intersection of the Maple Valley Highway and I-405 should assure access to public streets. The wall of I-405 and the Cedar River limit access but the City has managed two points of access, which seems appropriate. Two points of access also limits the number of driveways within the park system making it more internally user friendly. 20. The site is adjacent to the Cedar River trail system as well as the state and interstate highway system. Access should be reasonable. 21. Finally, another set of criteria,those for a Level I Site Plan(Section 4-9-200F),must be reviewed. Some of the criteria overlap those reviewed above. The criteria contain the following provisions: 1. Review of Impacts to Surrounding Properties and Uses. 2. Review of Impacts of a Proposed Site Plan to the Site. 3. Review of Circulation and Access. 4. Review of Signage. 5. Special Review Criteria for Hazardous Waste Treatment and Storage Facilities. 6. Review of Street Frontage Landscape. 22. Again,the development of the new aquatic complex should not impair the use of any surrounding properties or uses. It should not bring unnecessary traffic to the area and such traffic would be limited, after construction, to passenger vehicles in the main. The hours will generally not conflict with peak hour traffic demands. The buildings and pools have been located so as not to impact adjacent park or non-park uses. The design, as a whole, should enhance the general look of the campus and is designed to appear to be part of the existing campus. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 10 23. As already noted,the development will decrease the open space at this park. That seems a justifiable balancing of the interests inherent in creating a summer swimming venue at an existing,centrally located park facility. The applicant has minimized the intrusions but some loss will occur. 24. The two points of access are pretty well defined by the location and existing development pattern of a parcel located in the southeast quadrant of the I-405/Maple Valley Highway intersection. The main, signalized intersection will provide reasonable access to all points of the City. The secondary Houser Way tunnel is a limited but available route that has served reasonably well. The combination has limited the number of entrances and maintained parkland. The applicant has provided for internal vehicular and pedestrian circulation. A drop-off will provide a safety zone for arriving vehicles dropping off pedestrians. 25. The Park already has signs. As staff noted, any new signs would meet the City's own requirements. 26. While some chemicals for treating the pool might be considered hazardous,their number and quantity will be limited. Staff reported that they would be below triggering thresholds of the Aquifer Protection Ordinance. They would also be stored in legal forms and containers. 27. The applicant will not be altering any of the landscaping found along the streets adjacent to the subject site. Some ten larger,mature trees will be removed to accommodate the proposal but these are not frontage trees. Internal landscaping as well as the leisure pool will serve as both landscape and water elements for the new aquatic center. 28. In conclusion,the proposed Aquatic Center appears to be a well-designed complex in its own right but also will be well integrated into the existing facilities located at Cedar River Park. It will replace a solely missed element; the now closed Henry Moses Pool, in summer fun in the City. Recommendation: The City Council should approve the Site Plan for the City of Renton Aquatic Center subject to the following conditions: 1. The applicant shall comply with the conditions imposed by the ERC. 2. If the City can fund an upgrade to make the fencing of this gateway site more aesthetically pleasing it should do so while,clearly,not compromising the safety and security of patrons and the complex itself. ORDERED THIS 25th day of February, 2003.

Members, Renton Planning Commission Neil Watts,Development Services Director Larry Rude, Fire Marshal Econ. Dev. Administrator Lawrence J. Warren, City Attorney Larry Meckling,Building Official Transportation Systems Division Jay Covington, Chief Administrative Officer Utilities System Division Councilperson Kathy Keolker-Wheeler South County Journal Alex Pietsch,Economic Development Director Pursuant to Title IV, Chapter 8, Section 15 of the City's Code, request for reconsideration must be filed in writing on or before 5:00 p.m.,March 11,2003. Any aggrieved person feeling that the decision of the Examiner is ambiguous or based on erroneous procedure,errors of law or fact, error in judgment, or the discovery of new evidence which could not be reasonably available at the prior hearing may make a written request for a review by the Examiner within fourteen(14)days from the date of the Examiner's decision. This request shall set forth the specific ambiguities or errors discovered by such appellant, and the Examiner may, after review of the record, take further action as he deems proper. An appeal to the City Council is governed by Title IV,Chapter 8, Section 110,which requires that such appeal be filed with the City Clerk, accompanying a filing fee of$75.00 and meeting other specified requirements. Copies of this ordinance are available for inspection or purchase in the Finance Department, first floor of City Hall. If the Examiner's Recommendation or Decision contains the requirement for Restrictive Covenants,the executed Covenants will be required prior to approval by City Council or final processing of the file. You may contact this office for information on formatting covenants. The Appearance of Fairness Doctrine provides that no ex parte(private one-on-one)communications may occur concerning pending land use decisions. This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the proposal must be made in public. This public communication permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. - 8 T23N R5E E 1/2 ;�v� 0.6,0 \\.<'R—p'---- iFitemal-6: 0 7 - , , -6:5- \ R R_g r� --r- \ !!// RM-I A\ CA fir .-i/I \ _ ,,--R 1 k-ip\ /i-- c k- A d (; �$1) - / A RM\I '\ VE usl \ \- CD a c� , a. 5 .

Mr. Jordan explained that this site Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 2 plan review would be a recommendation to Council rather then a Hearing Examiner decision due to it being located in the Center Office Residential(COR)zone. The new City operated Aquatic Center would be located within the existing Cedar River Park site. The proposed Aquatic Center is to be constructed in the northeast corner of the site closest to Maple Valley Highway. The Cedar River is located south and east of the subject site. The Community Center Building and Carco Theatre are also located on this site. There is a large parking lot in the central portion of the property. The parks maintenance buildings are located east and south of the proposed aquatic center site. Interstate 405 and Houser Way are immediately west of the site. The Maple Valley Highway is located north and east of the site. The Stoneway concrete plant is east of the site. The Aquatic Center would include a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Activities with this proposal would include recreational uses, swim lessons,therapeutic uses and occasional swim meets. Construction is planned to begin in April of this year and be substantially completed by December 2003. The City expects to operate the pool from approximately Memorial Day to Labor Day weather permitting. Typical hours of operation will be from dawn to dusk. Access to the site is proposed from two locations. The primary access is proposed from Maple Valley Highway where there is a full-signalized intersection. The secondary access,which is limited to a right in,right out, is from Houser Way North. The Environmental Review Committee(ERC) issued a Determination of Non-Significance-Mitigated(DNS-M) with six mitigation measures for the project. There were no appeals filed. Five of the mitigation measures were standard erosion control mitigation measures. The last mitigation measure was for a Fire Impact Fee. Mr.Jordan reviewed several policies from the Comprehensive Plan and how they are applicable to the project. Staff believes that the Aquatic Center is a nice addition to the current recreational uses within the site. The site is already recreational and this would only be augmenting that use in a high quality manner. The applicant is not proposing any additional parking and they have done a fairly thorough investigation of getting pedestrian and vehicular access off the roads to the parking areas and to the aquatic center. In regard to conformance with land use regulations,the COR zone allows Aquatic Center uses as primary permitted uses in this zone. The Development Standards with regard to lot coverage allow up to 65 percent coverage in the COR zone. This particular project only has lot coverage of 6.5 percent with the additional 6,500 square feet of building area. In regard to setbacks,the proposed aquatic center is located 100 feet from the Maple Valley Highway and 500 feet from the Cedar River. It is also located 480 feet from Houser Way and 160 feet from the Stoneway Concrete plant. The Aquatic Center has substantial setbacks that would mitigate any potential concerns from neighboring properties. The required landscaping is already in place as part of the development. The proposed Aquatic Center at 19 feet in height is well below the 125 feet maximum allowed in the COR zone. There are an existing 400 parking stalls at the site. Development code requires one stall per 100 square feet. The zoning code did not have a ratio for parking for swimming pools so staff used the community center type parking requirements for the aquatic center use. This would have required an additional 266 parking stalls for Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 3 the Aquatic Center use;however,the applicant put together a pretty solid argument indicating that the one per 100 square feet is too high for the Aquatic Center and the demand would be far less. Secondly,the Community Center,Carco Theater and the Renton Aquatic Center will have different peak hours of operation and the 400 stalls currently available would be adequate. Staff reviewed this information and administration issued a parking modification for the project. The proposal is located within an existing park site and has already been utilized as recreation. Staff feels that because the existing uses are recreational there should be no impacts to surrounding properties. Construction activities would result in short term noise, dust and traffic impacts;however,these will be limited to the construction phase and would be subject to a construction mitigation plan. A geotechnical report was submitted for the project. The report indicated that the site is appropriate for this type of use. The ERC did mitigate erosion for the site with the primary emphasis on no impacts to the Cedar River. The ERC mitigation measure should minimize any impacts of the site plan to the site. In regard to questioning from the Examiner,Mr.Jordan stated that after construction the site would be fenced with chain link fence and separated from the rest of the park area for safety reasons. The site is located within the Aquifer Protection Area(APA)zone. There will be some typical pool treatment chemicals on-site;however,they are below the maximum allowed for the APA zone. Staff expects that the Aquatic Center would increase the property values in the vicinity of the site. A traffic study was not required for this project. The project is not providing any additional parking but what the applicant has done is propose some extensive striping. There is already a paved walkway from the parking area next to the Maple Valley Highway that leads right past the site and continues on to the other buildings. With respect to parking in the main parking lot the applicant has put together a fairly good striping plan to allow for safe vehicle and pedestrian movement. The Aquatic Center is largely comprised of an open outdoor recreation area. There are some buildings but they are limited to 19 feet in height and located in the south corner and staff does not expect these buildings to impede any light or air circulation to the site. The buildings are not going to impact any of the other recreational opportunities in staff's opinion. The proposed development would not generate any harmful or unhealthy conditions. There would be noise impacts related to increased traffic and activity normally associated with recreational use. The Fire and Police Departments have indicated that they have sufficient resources to adequately accommodate the subject proposal provided the applicant pay the required Fire Mitigation Fee. Police did extensively review this project and do have concerns with safety and did have some suggestions for the construction phase of the project. Staff does not expect any neighborhood deterioration or blight and in fact expects the opposite. One of the criteria for the COR zone is that planning incorporates public and private open space to provide adequate areas for passive and active recreation. The site is entirely dedicated to recreation and has both active and passive recreation opportunities. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 4 The plan does provide view corridors to the shoreline areas. Staff does not expect any view corridors to be blocked. The project is setback over 500 feet from the Cedar River and the buildings are limited to 19 feet in height. There is still access to the Cedar River and the aquatic center will not be blocking access in any way. Mr.Jordan stated that there is additional review criteria for the COR zone and asked to clarify that typically for the COR zone there is a requirement that the site plan reviews go through a Level II Site Plan Review. Because this proposal did not go through a Level II Site Plan Review,the additional criteria must be reviewed. Staff does not believe that the two buildings would be an over concentration. The majority of the site is still predominantly open space. The applicant attempted to locate the pool in a more flat area so that less grading would have to occur and to be the least impact to the Cedar River. The lighting plan clearly shows that the lighting would be adequate for not only safety but also security and the lighting does not spill onto neighboring properties and certainly does not spill onto the Cedar River site. Staff believes that the applicant has put together a good site plan trying to tie in the natural areas and the open space areas. The structures proposed should not be an overburden to the existing site or be out of scale with the existing buildings on the site. The applicant will not be adding any additional impervious surface due to parking. The swimming pools will be tied into the sewer system. The swim decks are below the threshold for any type of water quality treatment. This is a very low impact development on the existing Cedar River site. Mr.Jordan added that there would be quite a few landscaped areas throughout the site. Staff recommends approval of the Renton Aquatic Center with no conditions. Boris Srdar,Northwest Architectural Company,2201 6th Avenue,#1405, Seattle, WA 98121 stated that this is the first facility of this type in the area. This is the third project of this kind that he has worked on. Experience tells them that about 50 percent of people who use the pools do not require parking. These types of facilities are very popular with children from the age of seven into their early teens. Most of the vehicles that do park are not single occupancy vehicles they are families with children. These facts combined with the occupancy rate of the facility means that less then half of the parking would go to the pool. In response to questioning from the Examiner regarding fencing,Mr. Srdar stated that given the priorities of the pool and the amenities to meet the base cost they have decided to use the chain link fencing rather then a wrought iron or something else. Mr.Jordan stated that he has checked with the applicant and the difficulty is the budget. They all agree that the wrought iron fence is much more aesthetically pleasing. One issue is that on the northwestern boundary of the pool the fence has to be a certain height because of the location of the ball fields. It may be possible to use wrought iron in the front of the aquatic center and have the rest be painted cyclone. The Examiner called for further testimony regarding this project. There was no one else wishing to speak,and no further comments from staff. The hearing closed at 9:57 a.m. FINDINGS,CONCLUSIONS&RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 5 Findings: 1. The applicant,Dennis Culp,representing the City of Renton, filed a request for approval of a Site Plan for a new Aquatic Center. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non- Significance-Mitigated(DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. There was no opposition from the public regarding the subject proposal. 6. The subject site is located 1715 Maple Valley Highway. The subject site is located on the south side of the highway immediately east of I-405 and just east of downtown Renton. The subject site is located in the northeast corner of the Cedar River Park complex that contains the Renton Community Center building and Carco Theater. The Cedar River is located south of the subject site. 7. The subject site is approximately 240 feet wide(Maple Valley Frontage)by 320 feet deep. The subject site is approximately 1.75 acres of the approximately 20-acre park site. 8. The subject site was annexed to the City with the adoption of Ordinance 1212 enacted in April 1945. 9. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of Center Office and Residential uses,but does not mandate such development without consideration of other policies of the Plan. 10. The subject site is zoned COR(Center Office Residential)a zoning designation applied to the subject site in June 1993. The COR zone permits parks and aquatic facilities. 11. The site east of the subject site,the concrete plant, is also zoned COR. The concrete plant is in the process of being decommissioned. There is a CA(Commercial Arterial)zone north of the site,across Maple Valley Highway. The Cedar River corridor and slopes on its south side are zoned RC(Resource Conservation). 12. The applicant proposes developing an Aquatic Center that contains four components. It will contain two outdoor pools including a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Complementing the two pools will be two buildings. These buildings will be approximately 6,500 square foot. There will be a changing rooms building that is approximately 32 feet wide by 160 feet long located in the southern portion of the site. The concessions area will be west of the changing area and will be approximately 48 feet square. Additional restrooms are located in the northeast corner of the site. 13. The leisure pool will be an elaborate facility with river area,wave area as well as a plunge area and other features. 14. The buildings will be one-story or approximately 19 feet tall. The COR zone permits buildings of 10 Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 6 stories or 125 feet tall. 15. There will be internal landscaping and the applicant will be taking advantage of existing landscaping that borders the existing park along its edges and frontage. 16. Staff analyzed the parking requirements for the use as well as the other uses that share the entire site. Currently there are 400 parking stalls located on the site serving the community center and the theater. The Community Center requires one stall per 100 square feet or 354 stalls and those are all provided. Carco Theater requires one stall per four fixed seats or 75 stalls and only 46 are provided. That's a deficit of 29 stalls. Code does not specifically address either pools or the more elaborate Aquatic Center. Staff compared the use to indoor or outdoor arenas or stadiums,which require one stall per 100 square feet like the Community Center itself. Staff calculated the Aquatic Center would require 266 stalls. The City's consultant reviewed the site,parking usage and similar uses and determined that the existing 400 stalls could reasonably serve the pool patrons. In addition,they anticipate that the theater and pool would have different demand hours. They expect a number of the patrons to be children who will be dropped off by parents or arrive by bicycle or in carpools with friends. The applicant noted that there is room on the grounds to provide additional parking if it is determined that their is insufficient parking. They would prefer saving the lawn areas if the parking were unnecessary. The applicant was granted an Administrative Parking Modification from the Code based on these various analyses. 17. The subject site will have two points of access. The main entry will be the signal-controlled intersection along the Maple Valley Highway. A second access is Houser Way via a tunnel under I-405. There will be a pullout near the entrance to the pool complex to allow drop-offs. Traffic will circulate around the east side of the new complex. 18. The new complex will be approximately 500 feet from the Cedar River. It will be setback approximately 480 feet from Houser Way and slightly less from I-405. The complex will be setback approximately 100 feet from the Maple Valley Highway and 160 feet from its eastern property line,the one shared with the cement plant. 19. The proposal requires 10 feet of landscaping along the Maple Valley Highway setback. The current landscaping will provide that setback. 20. The development of the swimming complex will result in the loss of lawn area replaced by the complex as well as a large Big Leaf Maple and nine Pin Oak trees. 21. The applicant proposed using chain link fencing to provide security around the subject site. The pool needs to be protected from illegal entry,particularly after hours. The applicant also noted that the pool and its patrons need to be protected from balls that might go astray from the nearby playfields. This office suggested that since the applicant considers this a gateway site for the City that more appropriate, aesthetically pleasing fencing such as wrought iron be used. The applicant indicated budget constraints might limit the ability to upgrade but might be able to use it along the Maple Valley frontage. 22. The aquatic center would replace the previous pool(Henry Moses Pool)at Liberty Park,which was demolished in 1999. 23. Construction of the complex is planned to begin in April 2003 and be substantially completed by December 2003. 24. The subject site is located in the Aquifer Protection Zone. No impacts on water quality are anticipated.The Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 7 storage of pool cleaning chemicals will follow standard practices. Conclusions: 1. The COR Zoning requires that an approval of a Site Plan be done by the City Council in this case. The COR zoning provides an extensive list of criteria to judge whether a proposal is appropriate in the zone as well as criteria for a Level I Site Plan as well as the normal criteria for Site Plan review. Some of the criteria overlap. 2. The site plan ordinance provides a number of specific criteria for reviewing a site plan. Those criteria are generally represented in part by the following enumeration: a. Conformance with the Comprehensive Plan; b. Conformance with the Building and Zoning Codes; c. Mitigation of impacts on surrounding properties and uses; d. Mitigation of the impacts of the proposal on the subject site itself; e. Conservation of property values; f. Provision for safe and efficient vehicle and pedestrian circulation; g. Provision of adequate light and air; h. Adequacy of public services to accommodate the proposed use; The proposed use satisfies these and other particulars of the ordinance. 3. The COR designation in the Comprehensive Plan suggests a coherent,high quality development that takes advantage of natural amenities. The proposed complex has been designed to provide a center for recreational opportunities in a unified campus. The pool complex has been designed to fit in with the general size and scale of the existing Recreation and Carco buildings. The low-rise nature is intended to keep the site open appearing and minimize impacts on the nearby Cedar River. 4. The one-story buildings,the setbacks and landscaping meet the limits provided by the Zoning Code. Detailed analysis of building code and fire code compliance will be determined when the building permit is submitted for review. The proposal has been granted a modification from parking standards based on an analysis of current parking demands as well as projected demands of the specific use. 5. The low-rise complex should have few if any impacts on surrounding properties. The complex is setback 160 feet from adjoining private property to the east. It will have a 100-foot setback from Maple Valley and is separated from the Cedar River by the other uses already established on the subject site. The use of chain link fencing for such a prominent site is unfortunate. If the City can fund an upgrade to make this gateway site more aesthetically pleasing it should do so while,clearly,not compromising the safety and security of patrons and the complex itself. 6. The open space at Cedar River Park will be diminished by the complex and some older, larger trees will need to be removed. The tradeoff is providing a quality swimming complex and new landscaping inside Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 8 the complex should soften its appearance especially when coupled with the existing landscaping. The construction will have clear short-term impacts including noise. The completed facility should have few impacts other than possibly noise associated with boisterous patrons. It will also probably generate additional visitation to the park during the summer months when the pool is operating. 7. The development should not adversely affect property values. It is planned as a high quality addition to the recreational amenities offered by the City. 8. The proposal will use the existing parking lot,which has proved adequate in both terms of efficiency and circulation. The pool complex will have a drop-off lane near its entrance to accommodate parents dropping off children to use the complex. The applicant will be restriping some of the parking and walking areas to accommodate pedestrians. 9. There will be adequate light and air in and around the one-story, open pool complex. 10. There is a full complement of public services to accommodate the facility. 11. The subject site is not located in the Urban Center Design Overlay area and is not subject to those special regulations. 12. Section 4-9-200E1k provides "Additional Special review Criteria for COR Zone Only:" and those in part include: 1. The plan is consistent with the Planned Action Ordinance, if applicable. 2. The plan creates a compact,urban development that includes a compatible mix of uses where appropriate. 3. The plan provides an overall urban design concept that is internally consistent and harmonious with development on adjacent sites. 4. The plan incorporates public and private open spaces to provide adequate area for passive and active recreation by the occupants/users of the site and/or protecting existing natural systems. 5. The plan provides view corridors to the shoreline areas where applicable. 6. Public access is provided to water and/or shoreline areas. 7. The plan provides distinctive focal points such as public area plazas,prominent architectural features or other items. 8. The plan assures adequate access to public streets. 9. The plan accommodates and promotes transit,pedestrian and other alternative modes of transportation. 13. The Aquatic Center proposal does not need a"Planned Action Ordinance." 14. The Aquatic Center is part of an urban park system. It contains,as a park should, open space. It is not an inherently compact urban proposal but concentrates many of Renton's community recreation facilities in Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 9 this one location. 15. The entire park concept has been developed to be homogeneous. While new elements such as the pool complex and the Community facility are or have been added,they are designed to blend with the existing park and facilities including the Carco Theater. Development around the site is sparse with I-405 and the Cedar River providing the most defined uses and the cement plant being phased out over the next few years. 16. The park provides its own open space unlike a private development proposal. The immediate pool complex provides the open water pools and two smaller buildings. The new complex should not affect the existing natural systems,which would be the Cedar River and the underlying drinking water aquifer. 17. The proposed aquatic complex should not severely impact any view corridors. Other buildings are already located between the Maple Valley Highway and the Cedar River. In addition,nothing about the new complex would detract from current access to the river and it's viewing and seating areas. 18. The aquatic center probably will become a new focal point for the Cedar River Park in itself. The entire recreational complex,though, serves this function. Hopefully,a more aesthetic fencing arrangement can further enhance the complex's prominent features. 19. The park's location at the intersection of the Maple Valley Highway and I-405 should assure access to public streets. The wall of I-405 and the Cedar River limit access but the City has managed two points of access,which seems appropriate. Two points of access also limits the number of driveways within the park system making it more internally user friendly. 20. The site is adjacent to the Cedar River trail system as well as the state and interstate highway system. Access should be reasonable. 21. Finally,another set of criteria,those for a Level I Site Plan(Section 4-9-200F),must be reviewed. Some of the criteria overlap those reviewed above. The criteria contain the following provisions: 1. Review of Impacts to Surrounding Properties and Uses. 2. Review of Impacts of a Proposed Site Plan to the Site. 3. Review of Circulation and Access. 4. Review of Signage. 5. Special Review Criteria for Hazardous Waste Treatment and Storage Facilities. 6. Review of Street Frontage Landscape. 22. Again,the development of the new aquatic complex should not impair the use of any surrounding properties or uses. It should not bring unnecessary traffic to the area and such traffic would be limited, after construction,to passenger vehicles in the main. The hours will generally not conflict with peak hour traffic demands. The buildings and pools have been located so as not to impact adjacent park or non-park uses. The design,as a whole, should enhance the general look of the campus and is designed to appear to be part of the existing campus. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 10 23. As already noted,the development will decrease the open space at this park. That seems a justifiable balancing of the interests inherent in creating a summer swimming venue at an existing, centrally located park facility. The applicant has minimized the intrusions but some loss will occur. 24. The two points of access are pretty well defined by the location and existing development pattern of a parcel located in the southeast quadrant of the I-405/Maple Valley Highway intersection. The main, signalized intersection will provide reasonable access to all points of the City. The secondary Houser Way tunnel is a limited but available route that has served reasonably well. The combination has limited the number of entrances and maintained parkland. The applicant has provided for internal vehicular and pedestrian circulation. A drop-off will provide a safety zone for arriving vehicles dropping off pedestrians. 25. The Park already has signs. As staff noted, any new signs would meet the City's own requirements. 26. While some chemicals for treating the pool might be considered hazardous,their number and quantity will be limited. Staff reported that they would be below triggering thresholds of the Aquifer Protection Ordinance. They would also be stored in legal forms and containers. 27. The applicant will not be altering any of the landscaping found along the streets adjacent to the subject site. Some ten larger,mature trees will be removed to accommodate the proposal but these are not frontage trees. Internal landscaping as well as the leisure pool will serve as both landscape and water elements for the new aquatic center. 28. In conclusion,the proposed Aquatic Center appears to be a well-designed complex in its own right but also will be well integrated into the existing facilities located at Cedar River Park. It will replace a solely missed element;the now closed Henry Moses Pool, in summer fun in the City. Recommendation: The City Council should approve the Site Plan for the City of Renton Aquatic Center subject to the following conditions: 1. The applicant shall comply with the conditions imposed by the ERC. 2. If the City can fund an upgrade to make the fencing of this gateway site more aesthetically pleasing it should do so while,clearly,not compromising the safety and security of patrons and the complex itself.

PROJECT DESCRIPTION/BACKGROUND The applicant is requesting Environmental (SEPA) Review and Hearing Examiner/City Council Site Plan Review approval for the construction of a new City operated aquatic center, which would be located within the Cedar River Park recreational area. The proposed aquatic center is planned to be constructed in the northeast corner of the site, currently utilized as an existing ball field and picnic area. The project is located within the Center Office Residential (COR) zoning and comprehensive plan designation area. The proposed Aquatic Center would include a 9,520 square foot leisure pool, 3,837 square foot lap pool and 6,500 square feet of changing rooms and concession areas. Activities with this proposal would include recreational use, swim lessons, therapeutic uses and occasional swim meets. Construction is planned to begin in April of 2003 and be substantially completed by December of 2003. Once the project is completed, the City is expecting to operate the pool from Memorial Day through Labor Day (weather permitting). Typical hours of operation would be from dusk until dawn (it should be noted that specific pool hours have not been established as of the writing of this report). Access to the site is proposed from two locations. The primary access point is proposed from Maple Valley Highway, which is located directly north of the subject site. Secondary access to the proposed use HEXRPT.doc City of Renton P/B/PW Department liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 4 of 14 is from Houser Way North, which is located west of the subject site. The Cedar River Park site currently contains the Renton Community Center building, Carco Theater, several sport fields and a picnic area, all of which will remain as part of this proposal. In addition, the site has approximately 400 parking stalls, which are proposed to be shared by all uses. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C, 1971 as amended), on January 21, 2003 the Environmental Review Committee issued a Determination of Non-Significance- Mitigated, for the project. The DNS-M included six mitigation measures. A 14-day appeal period commenced on January 24, 2003 and ended on February 10, 2003. No appeals of the threshold determination were filed 3. COMPLIANCE WITH ERC MITIGATION MEASURES Based on an analysis of probable impacts from the proposal, the Environmental Review Committee (ERC) issued the following mitigation measures with the Determination of Non-Significance-Mitigated: 1. Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. 6. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per square foot of new commercial building area prior to the issuance of building permits. 4. STAFF REVIEW COMMENTS Representatives from various city departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH GENERAL SITE PLAN APPROVAL CRITERIA As per RMC 4-9-200E, "The Reviewing Official shall review and act upon site plans based upon comprehensive planning considerations and the following criteria. These criteria are objectives of good site plans to be aimed for in development within the City of Renton. However, strict compliance with any H EXRPT.doc City of Renton P/B/PW Department iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 5 of 14 one or more particular criterion may not be necessary or reasonable. These criteria also provide a frame of reference for the applicant in developing a site, but are not intended to be inflexible standards or to discourage creativity and innovation. The site plan review criteria include, but are not limited to, the following": (A) CONFORMANCE WITH THE COMPREHENSIVE PLAN, ITS ELEMENTS & POLICIES The Comprehensive Plan Land Use Map designation for the project property is Center Office Residential (COR). The purpose of the "Center Office Residential" designation is to provide a mix of intensive office, hotels and convention centers and residential activity in a high-quality master planned development, that is integrated with the natural environment. The following Comprehensive Plan policies are applicable to the proposal: Objective LU-U. Encourage projects throughout the designation which create cohesive, quality and landmark developments integrated with natural amenities. The intention is to create a compact, urban development with high amenity values that is a gateway to the City. The proposed aquatic center has been designed and situated on the site to appropriately interact with the surrounding environment, in addition to being a visible landmark within a gateway corridor to the City. Staff fully expects the proposed aquatic center to be a"high value amenity"to the City. Policy LU-125. Commercial uses such as retail and services should also be permitted provided that they support the primary uses of the site and are architecturally integrated into the development. The proposed aquatic center has been architecturally designed to be integrated into the existing Cedar River Park via locating the aquatic use in an underutilized location of the site. Furthermore, the aquatic center is expected to augment the existing Cedar River Park (recreational) use by providing additional aquatic recreational uses on site. Policy LU-133. Internal site circulation should be primarily pedestrian oriented. The subject site contains approximately 400 existing on-site parking stalls. The applicant has proposed to provide extensive pedestrian circulation from both the parking areas and the main entrance (Maple Valley Highway) to the proposed aquatic center. The pedestrian circulation would primarily utilize existing sidewalks and walkways; however, the applicant has also proposed to provide additional stripping within the existing parking areas. Policy LU-134. Vehicular access to each proposed development should be from a major street with the number of access points reasonably minimized. Access to the proposed aquatic center would be provided primarily from Maple Valley Highway. Secondary access would be provided from Houser Way North (right in/right out), through the existing Cedar River Park site. (B) CONFORMANCE WITH LAND USE REGULATIONS The subject site is zoned Center Office Residential (COR). The COR zone was established to provide for a wide variety of uses including commercial, residential, entertainment and personal/professional services. The CD zone allows aquatic center uses (recreational/existing parks) uses as primary permitted uses within this zone. Development Standards The subject site is located in the Commercial Office Residential land use designation. The following standards apply to project proposed within this land use designation: Lot Coverage—The maximum lot coverage allowed in the COR zone is 65% for projects without structured parking. In this case, the additional 6,500 square feet of building area (not including the pools) brings the total lot coverage of the site to 6.5% (51,000 square feet of existing building area + 6,500 square feet of new building area = 57,500 total building square feet / 877,762 total site square feet=6.5%), well below the maximum lot coverage allowed within the zone. HEXRPT.doc City of Renton P/B/PW Department _'iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 6 of 14 Setbacks/Landscaping—The minimum and maximum setbacks are determined through the site plan review process. In this case, the proposed aquatic center is located over 100 feet from Maple Valley Highway (front yard) and over 500 feet from the Cedar River (rear yard). In addition, the proposal is located approximately 480 feet from Houser Way North (side yard along a street) and 160 feet to the eastern property line (interior side yard). Staff anticipates that the proposed setbacks would adequately mitigate any concerns from neighboring properties. The COR development standards also prescribe a minimum landscape area along freeway frontages. In this case, a 10-foot landscaped setback from Maple Valley Highway would be required. However, the required landscaping is already in place as part of the existing Cedar River Park. Staff does not recommend any additional freeway frontage landscaping as part of this development. It should be noted that the construction of the aquatic center would require the removal of one Big Leaf Maple tree and nine Pin Oak trees. In addition, all the play field grass within the project area would be removed. However, once the aquatic center is constructed, the applicant has proposed to plant ornamental trees, shrubs and ground cover around the perimeter of the aquatic center. Furthermore, all disturbed ball field grass, outside of the project area, would be replanted once the aquatic center is constructed. Height — The COR zone allows a maximum building height of 10 stories or 125 feet. The maximum height associated with the proposed aquatic center is 19 feet (concession and changing room buildings), which is well below the maximum allowed height within this zone. Parking, Loading, and Driveway Regulations — The City of Renton's parking development standards do not specifically list out aquatic recreation as a use within the prescribed parking ratios. The closest use within the parking table is outdoor and indoor sports arenas, auditoriums, stadiums, movie theaters and entertainment clubs. Those uses require one parking stall per 100 square feet of floor area or one parking stall per every four fixed seats. The following table outlines the required parking: Use Formula Required Provided Community Center 1 stall per 100 square feet 354 354 Carco Theater 1 stall per every 4 fixed seats 75 46 Aquatic Center 1 stall per 100 square feet 266 N/A Total 695 400 However, the applicant has requested an Administrative Parking Modification, which was granted on January 27, 2003. The approval was based on supporting documentation, which demonstrated that one stall per 100 square feet of aquatic center area was in excess of the actual parking demand generated from this type of use. In addition, the City's consultant successfully demonstrated peak parking demand for each use within the site would be at different times for different uses (i.e. theater parking would be at night, while aquatic center parking would be during the day). The aquatic center would be accessed from existing entrance points along Maple Valley Highway (primary) and Houser Way North (secondary limited to right in/right out). No new access points are planned as part of this development. The existing parking configuration conforms to the minimum requirements for drive aisle dimensions and the provision of ADA accessible parking stalls. Staff does not recommend any changes to this area of the site nor are any proposed. Urban Center Design Overlay Regulations The subject site is located outside of the Urban Center Design Overlay Regulations; therefore, they are not applicable to this project. (C) MITIGATION OF IMPACTS TO SURROUNDING PROPERTIES AND USE The proposal is located within the existing City of Renton Cedar River Park site, which is located between Maple Valley Freeway and the Cedar River. As the subject area is currently utilized for HEXRPT.doc City of Renton P/B/PW Department . .Amine!),Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 7 of 14 recreational activities (existing ball field and picnic area), staff does not anticipate the proposed aquatic center use (also recreational) to impact the surrounding properties. In addition, the project site is surrounded by designated state highways (SR169), roads (Houser Way North) and a commercially zoned property, which is currently being utilized as a cement batch plant (to be decommissioned in the near future). Construction activities would result in short-term noise, dust and traffic impacts on surrounding properties. These impacts would be limited to the construction phase of the project, which is estimated to be have a total duration of approximately 10 months (March 2003 to December 2003). The applicant would be required to submit a Construction Mitigation Plan outlining measures to be employed for minimizing dust, noise and traffic impacts during construction prior to the issuance of any building or construction permit. Potential short-term noise and traffic impacts would result from the initial construction of the project. Existing code provisions that limit construction work hours, and requiring the applicant to provide a construction mitigation plan would also mitigate these impacts. (D) MITIGATION OF IMPACTS OF THE PROPOSED SITE PLAN TO THE SITE A geotechnical report prepared by Associated Earth Sciences, Inc. dated December 2002 was submitted with the project application. The report indicates the site slopes very gently (less than 5%) towards the Cedar River located approximately 700 to 800 feet to the southwest of the most northern property boundary. The reports states that the subsurface conditions consist of 6-inches of sod and topsoil. Beyond the sod and topsoil, the alluvium consists of silty to clean sand and gravel. In general, the upper horizon of the alluvium was loose to medium dense silty sand. The report concludes that the site is suitable for the proposed development. Only minor post- construction settlement of the underlying material due to the superimposed building loads is anticipated. Potential erosion impacts that could occur during project construction would be adequately mitigated by the five erosion control mitigation measures imposed on the project by the City's Environmental Review Committee. In addition to existing City Code requirements for approval of a Temporary Erosion and Sedimentation Control Plan (TESCP) pursuant to the King County Surface Water Design Manual (KCSWDM) and an approved Construction Mitigation Plan prior to issuance of Construction Permits. The subject site is located within the Aquifer Protection Area (APA) and some typically associated swimming pool chemicals would be kept on site. However, staff has verified the amount and type of chemicals required to operate the aquatic center are below the maximum allowed quantities permitted in this APA zone. (E) CONSERVATION OF AREA-WIDE PROPERTY VALUES The proposed aquatic center development is expected to increase property values in the vicinity of the site. Moreover, providing additional recreational opportunities in an area of the City that already provides many recreational activities would only attract more individuals to this area of the City. Staff expects the aquatic center to attract more patrons to this area of the City, which may add value to surrounding commercial properties as demand for additional goods and services are generated. Therefore, over the long-run, existing commercial property values in the immediate vicinity of the project site would be enhanced. (F) SAFETY AND EFFICIENCY OF VEHICLE AND PEDESTRIAN CIRCULATION A traffic study was not required as part of this proposal as staff concluded that the City had adequate traffic flow information on file. In addition, the site is currently being utilized as a recreational destination, which the proposed aquatic center would not change; therefore, additional traffic analysis was determined not to be necessary. As indicated previously, the project is not proposing to provide additional parking stalls. Instead, the applicant has requested to utilize the subject site's approximately 400 existing parking stalls, which provide adequate aisle widths and back-out distances for safe and efficient vehicular HEXRPT.doc City of Renton P/B/PW Department iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 8 of 14 circulation. Nevertheless, the applicant has elected to provide additional pedestrian striping, which would facilitate safe pedestrian circulation throughout the existing parking area to the proposed aquatic center. In addition, the project would utilize an existing walkway from Maple Valley Highway to the subject aquatic center area, which would actively keep pedestrians outside the traffic flow of vehicles entering or exiting the property. Construction truck hauling hours are limited to between 8:30 a.m. to 3:30 p.m. under the Development Guidelines Ordinance in order to avoid conflicts with peak hour traffic. The Traffic Planning Section will review construction-related impacts prior to issuing final construction permits. (G) PROVISION OF ADEQUATE LIGHT AND AIR The proposed aquatic center is largely comprised of outdoor swimming pool areas with associated swim decks; thereby allowing adequate light and air circulation throughout the project site. However, the applicant is proposing 6,500 square feet dedicated to changing rooms and concession areas for aquatic center patrons. These one-story structures (approximately 19 feet high) would be located in the southwest corner of the project site. Staff does not anticipate that the one-story buildings would block light and air to the mostly outdoor facility. (H) MITIGATION OF NOISE, ODORS AND OTHER HARMFUL OR UNHEALTHY CONDITIONS It is anticipated that the most significant noise, odor and other potentially harmful impacts would occur during the construction phase of the project. The applicant would be required to submit a Construction Mitigation Plan that provides measures to reduce construction impacts such as noise, control of dust, traffic controls, etc. prior to any construction/building permits being issued. The proposed development would not generate any harmful or unhealthy conditions. There would be noise impacts including increased traffic and activity that are normally associated with a recreational use. In addition, all stored swimming pool chemicals would be kept in a secure and contained area and only the minimum amount necessary to operate the pool would be kept on site. Nevertheless, minor pool treatment chemical smells (typically associated with a swimming pool) may be present during normal operation of the aquatic center. However, staff does not anticipate the amount of chemicals used to operate the pool to be harmful or cause unhealthy conditions. (I) AVAILABILITY OF PUBLIC SERVICES AND FACILITIES TO ACCOMMODATE THE PROPOSED USE Fire Department and Police staff have indicated that the City's existing facilities and resources are adequate to accommodate the subject proposal, provided that the applicant pay the appropriate Fire Mitigation Fee. Therefore, the City's Environmental Review Committee required the applicant to pay a Fire Mitigation Fee in the amount of $0.52 per square foot of new commercial building area. In addition, the City's Public Works department has indicated there are sufficient utilities in the area to serve this development and that the existing street system is adequate for this type of project. (J) PREVENTION OF NEIGHBORHOOD DETERIORATION AND BLIGHT The proposal would enhance an existing recreational area of the City via incorporating a family aquatic center into an existing recreation destination. Staff fully anticipates that the City's investment in the area would serve to prevent neighborhood deterioration and blight. Furthermore, the increase in recreational uses to this area of the City would generate more demand for additional goods and services, which other commercial property owners in this vicinity of the City may benefit from. (K) CONSISTENCY WITH ADDITIONAL COR SITE PLAN APPROVAL CRITERIA Per RMC 4-9-200E1 k, "Additional Special review Criteria for COR Zone Only:" the following items must be reviewed when a site plan review application is being conducted within the COR zone: HEXRPT.doc City of Renton P/B/PW Department liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 9 of 14 1. The plan is consistent with the Planned Action Ordinance, if applicable: This requirement is not applicable as the subject proposal did not require a Planned Action Ordinance. 2. The plan creates a compact, urban development that includes a compatible mix of uses where appropriate: The aquatic center is proposed to be located in an existing recreational area of the City. The aquatic center (recreational use) is proposed to replace a portion of the existing sports ball fields and picnic area currently located within the Cedar River Park site. As the proposed use is recreational, staff anticipates that the project would be compatible with the existing uses on site. 3. The plan provides an overall urban design concept that is internally consistent and harmonious with development on adjacent sites: As the Cedar River Park site is surrounded by the Maple Valley Highway to the north, the Cedar River to the south, Houser Way North to the west, and a cement batch plant to the east (to be decommissioned in the near future), staff does not anticipate the proposed aquatic center to be incompatible with the neighboring sites. In addition, the aquatic center recreational use is proposed on the existing Cedar River Park site, which is already utilized as a recreational destination within the City of Renton. 4. The plan incorporates public and private open spaces to provide adequate area for passive and active recreation by the occupants/users of the site and/or protecting existing natural systems: The proposed aquatic center would be located on the existing Cedar River Park site, which already provides open space for both passive and active recreation. The aquatic center would provide additional active recreational opportunities within the Cedar River Park property. Furthermore, the proposed aquatic center (recreational) use would be located over 500 feet from the Cedar River. The existing natural river system would not be adversely affected. 5. The plan provides view corridors to the shoreline areas where applicable: The subject aquatic center would be located over 500 feet from the Cedar River; therefore, views to the shoreline would not be obstructed. It should also be noted that the location of the Community Center Building and the Carco Theater Building block some of the view corridors within the Cedar River Park to the Cedar River. 6. Public access is provided to water and/or shoreline areas: The aquatic center has been designed to provide water-swimming activities for residents throughout the area. In addition, hasbeen located such that it would not impede citizens from reachingthe Cedar the project p River shorelines, where existing access is already granted within the Cedar River Park site. 7. The plan provides distinctive focal points such as public area plazas, prominent architectural features or other items: The aquatic center has been designed as a public outdoor water theme park, which provides a focal point and a public area within an existing community park. 8. The plan assures adequate access to public streets: The aquatic center has been designed to utilize two existing access points, which lead to public streets. Primary access would be provided from Maple Valley Highway, which is located north and east of the proposed aquatic center and has a full turning movement intersection regulated by a traffic signal. Secondary access would be provided from Houser Way North, which is located west of the subject site and is limited to signalized right in/right out turn only. 9. The plan accommodates and promotes transit, pedestrian and other alternative modes of transportation: The proposed aquatic center is located along a state route, which would provide adequate vehicular access to the site. In addition, this area of the City is located near other recreational uses (i.e. Liberty Park, Cedar River Trail), which would allow pedestrians to easily walk to the site. Furthermore, the applicant has proposed to clearly stripe pedestrian pathways from the existing parking area within the Cedar River Park site to the aquatic center, which would ensure safe pedestrian circulation throughout the site. (L) ADDITIONAL REVIEW CRITERIA FOR LEVEL I SITE PLANS As per RMC 4-9-200F, "Additional Review Criteria For Level I Site Plans"the following items must be reviewed when a Level I site plan review application did not previously undergo a Level II Site Plan Review process: HEXRPT.doc City of Renton P/B/PW Department iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 10 of 14 1. Review of Impacts to Surrounding Properties and Uses: a. Mitigation of undesirable impacts of proposed structure and site layouts that could impair the use or enjoyment or potential use of surrounding uses and structure and of the community: Staff does not anticipate the proposed aquatic center to impair the use or enjoyment of the existing Cedar River Park site. Conversely, staff anticipates that the proposed aquatic center would enhance the existing recreational opportunities currently undertaken within the Cedar River Park site. b. Mitigation of undesirable impacts when an overscale structure, in terms of size, bulk, height, and intensity, or site layout is permitted that violates the spirit and/or intent of the Zoning code and impairs the use, enjoyment or potential use of surrounding properties: The majority of the proposed aquatic center is comprised of open-air swimming areas, which would not be out of scale with the surrounding area. In addition, the 6,500 square feet of proposed new concession and changing room areas is limited to one-story and is not expected to impact adjacent properties. Finally, the structures are setback over one- hundred feet from the neighboring property to the east, which is currently utilized as a cement batch plat (to be decommissioned in the near future). c. Provision of a desirable transition and linkage between uses and to the street, utility, walkway and trial systems in the surrounding area by the arrangement of landscaping, fencing and/or other buffering techniques, in order to prevent conflicts and to promote coordinated and planned benefit from and access to such elements: The aquatic center has been located such that pedestrians walking from Maple Valley Highway would have direct pedestrian pathway access to the proposed aquatic area. Furthermore, the applicant has proposed to stripe new pedestrian walkways within the existing parking area, in order to provide a safe and efficient pedestrian pathway from the existing parking lot to the aquatic center entrance. d. Consideration of placement and scale of proposed structures in relation to the natural characteristics of a site in order to avoid overconcentration of structures on a particular portion of a site such that they create a perception of greater height or bulk than intended under the spirit of the Zoning Code: The aquatic center use is proposed to be located in a flat area of the Cedar River Park site in order to minimize the amount of grading required for the below-grade swimming pools. In addition, the applicant has elected to locate the aquatic center over 500 feet from the Cedar River in order to avoid any negative impacts to that water body. Finally, the proposed aquatic center buildings would be located several hundred feet from the community center building and the Carco Theater. Therefore, staff does not expect the aquatic center use to overconcentrate both the existing recreational opportunities and the existing buildings within the Cedar River Park site. e. Effective location, design and screening of parking and service areas in order to promote efficient function of such facilities, to provide integrated facilities between uses when beneficial, to promote `campus-like" or `park-like" layouts in appropriate zones and to prevent unnecessary repetition and conflict between uses and service area or facilities: The applicant is proposing to utilize the existing parking lot, which would be located behind the proposed aquatic center area. As the site is currently utilized for outdoor recreational opportunities, the applicant has attempted to locate the aquatic center in such a manner that provides additional recreational opportunities for citizens. Finally, staff expects the addition of an aquatic center within the Cedar River Park to enhance the existing "park-like"atmosphere that presently exists. f. Mitigation of the unnecessary and avoidable impacts of new construction on view from existing buildings and future developable sites, recognizing the public benefit and desirability of maintaining visual accessibility to attractive natural features and of promoting "campus-like" or "park-like" setting in appropriate zones: The proposed aquatic center use is comprised of mostly open-air swimming areas, which would not restrict views from existing buildings or future development. The 6,500 square feet of proposed concession and changing room areas is limited to one-story and would be less than 20 feet in height. Because the proposed structures are located towards the HEXRPT.doc City of Renton P/B/PW Department 'urinary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 11 of 14 northern boundaries of the site (500 feet from the Cedar River) and are limited to one story in height, staff does not anticipate the structures to block future or existing views of the Cedar River. g. Provision of effective screening from public streets and residential uses for all permitted outdoor storage areas (except auto and truck sales), for surface mounted utility equipment and for all refuse and garbage containers, in order to promote a "campus-like" or`park-like"setting where appropriate and to preserve the effect and intent of screening or buffering other wise required by the Zoning Code: The applicant has proposed to utilize the existing screened refuse and garbage containment system currently in operation within the Cedar River Park site. No additional outdoor storage areas or surface mounted utility equipment have been proposed. h. Consideration of placement and design of exterior lighting in order to avoid excessive brightness or glare to adjacent properties and streets: The applicant has proposed eight pole mounted lights, which would be located throughout the aquatic center site. In addition, there would be several wall-mounted lights along the interior of the concession and changing room-building walls. According to the lighting plan submitted with the building permit applicant, each light would be shielded and focused downward onto the property within the aquatic center area. As the aquatic center site is located over 100 feet from the nearest property boundary, staff does not anticipate any light spillage to occur outside of the Cedar River Site. In addition, staff does not expect any light spillage to occur within the Cedar River, as the proposed aquatic center is over 500 feet to the north of the river. However, the applicant contends that the lighting plan would provide enough lighting to adequately illuminate the site for safety and security purposes. 2. Review of Impacts of a Proposed Site Plant to the Site: a. Building Placement and spacing to provide for privacy and noise reduction; orientation to views and vistas and to site amenities, to sunlight and prevailing winds and to pedestrian and vehicle needs: The majority of the proposed aquatic center is comprised of open-air swimming areas, which are not expected impede sunlight and the prevailing winds. The 6,500 square feet of new buildings are limited to one-story in height and are not expected to shade or block the sun and prevailing winds within the site. Privacy and noise reduction are not relevant in this situation as the proposed use in an open-aired aquatic center, within an existing recreational site. b. Consideration of placement and scale of proposed structures in relation to the openness and natural characteristics of a site in order to avoid overconcentration of the impression of oversized structures: As the proposal is for an open-aired aquatic center with very little new building space, staff does not expect an overconcentration of buildings or oversized appearing structures to occur within the Cedar River Park site. As noted previously, the majority of the site would remain open and in a more natural state, staff anticipates a lot coverage of 6.5% upon project completion. c. Preservation of the desirable natural landscape through retention of existing vegetation and limited soil removal, insofar as the natural characteristics will enhance the proposed development: The applicant has elected to locate the proposed aquatic center in a relatively flat area of the Cedar River Park site, which should minimize the amount of grading. However, the swimming pools are proposed to be below grade, which would require excavation regardless of the natural characteristics of the site. It should also be noted that the aquatic center is proposed to be located over 500 feet from the Cedar River, which was intended to preserve the natural landscape in that area of the Cedar River Park site. However, some of the existing trees and landscaping would be removed as part of this proposal. d. Use of existing topography to reduce under cutting, filling and retaining walls in order to prevent erosion and unnecessary storm water runoff and to preserve stable natural slopes and desirable natural vegetation: The applicant has elected to locate the proposed aquatic center in a relatively flat area of the site, which should minimize the amount of grading required. However, as the proposal is for a below-grade swimming area, HEXRPT.doc City of Renton P/B/PW Department . ._liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 12 of 14 excavation would be necessary. The City's existing erosion control measures along with the Environmental Review Committee mitigation measures would alleviate any stormwater/erosion control issues. e. Limitation of paved or impervious surface, where feasible, to reduce runoff and increase natural infiltration: The proposed aquatic center has been designed to minimize the amount of impervious surface created by locating the use within a developed site. Moreover, the applicant has elected to locate the aquatic center within a site that already contains impervious parking and walkway areas, so no additional vehicular related impervious areas have to be created. Furthermore, the applicant has elected to locate pervious planting areas wherever practical throughout the aquatic center site, which would limit the amount of impervious area created as part of this development proposal. f. Design and protection of planting areas so that they are not susceptible to damage from vehicles or pedestrian movements: The area within the Cedar River Park where the aquatic center use is proposed is mainly comprised of field grass and ornamental oak trees. Once the aquatic center is constructed, the existing roadways and pedestrian access points within the Cedar River Park site would be utilized to access the aquatic center. In addition, the areas surrounding the aquatic center use are mainly comprised of field grass and ornamental trees. It should be noted that some of the ornamental trees would be removed as part of this proposal; however, the applicant has elected to locate several planting areas throughout the aquatic center site were ever practical. g. Consideration of building form and placement and landscaping to enhance year-round conditions of sun and shade both on-site and on adjacent properties and to promote energy conservation: The majority of the aquatic center use is comprised of open-air swimming areas, which would only be utilized during warm weather conditions. Therefore, staff does not expect the proposed use to impact adjacent properties nor negate energy conservation. 3. Review of Circulation and Access: a. Provision of adequate and safe vehicular access to and from all properties: As this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. b. Arrangement of the circulation pattern so that all ingress and egress movement may occur at as few points as possible along the public street, the points being capable of channelization for turning movements: As this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. c. Coordination of access points with adjacent properties, when feasible: This is not feasible as this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. d. Coordination of access points on a superblock basis so that vehicle conflicts and vehicle/pedestrian conflicts are minimized: As this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. e. Orientation of access points to side streets or frontage streets rather than directly onto arterial streets, when feasible: This is not feasible as this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. f. Promotion of the safety and efficiency of the internal circulation system, including the location, design and dimensions of vehicular and pedestrian access points, drives, parking, turnarounds, walkways, bikeways and emergency access ways: This is not feasible as this proposal is only adding additional recreational uses within the existing Cedar River Park site. The applicant has not proposed to modify the existing access HEXRPT.doc City of Renton P/B/PW Department . ._liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 13 of 14 points or internal circulation patterns. In addition, the applicant has proposed to utilize the existing parking areas within the Cedar River Park site, which meet current safety requirements. g. Separation of loading and delivery areas from parking and pedestrian areas: There are no loading or delivery areas proposed with the aquatic center use. h. Provisions for transit and carpool facilities and access here appropriate: The aquatic center has been designed to accommodate vehicles entering the site and having the ability to drop-off passengers near the main entrance of the aquatic center. The drop-off point is located toward the southeast corner of the aquatic center, which would provide for fast, efficient and safe drop-off capabilities. i. Provision for safe and attractive pedestrian connection between parking areas, building, public sidewalks and adjacent properties: The applicant has located the proposed aquatic center use such that existing pedestrian pathways from Maple Valley Highway would be utilized from individuals walking to the site. In addition, the applicant has proposed to stripe the existing parking area, in order to clearly denote the pedestrian pathway to the proposed aquatic center from the parking areas. 4. Review of Signage: a. Employment of signs primarily for the purpose of identification: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. b. Management of sign elements, such as size, location, and arrangement so that signs complement the visual character of the surround area and appear in proportion to the building and site to which they pertain: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. c. Limitation of the number of signs to avoid visual clutter and distraction: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. d. Moderation of surface brightness or lighting intensity except for the necessary for sign visibility: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. e. Provision of an identification system to allow for quick location of buildings and addresses: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. 5. Special Review Criteria for Hazardous Waste Treatment and Storage Facilities: a. Above-ground hazardous waste treatment and storage facilities shall be constructed with containment controls, which will prevent the escape of hazardous waster in the event of an accidental release from the facility. Such controls shall conform with all adopted Federal, State and local design and construction standards: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). b. Underground hazardous waste treatment and storage facilities shall comply with RMC4-5- 120, Underground Storage Tank Secondary Containment Regulations: The proposal does not include any hazardous waste treatment and/or storage facilities. c. Hazardous waste treatment and storage facilities shall comply with article 80 of the Uniform Fire Code as adopted by ordinance by the City of Renton: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). HEXRPT.doc City of Renton P/B/PW Department _liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 14 of 14 d. A hazardous waste spill contingency plan for immediate implementation in the event of a release of hazardous wastes at the facility shall be reviewed and approved by the Renton Fire Department prior to issuance of any permits: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). e. The location of all on-site and off-site facilities must comply with the State siting criteria as adopted in accordance with RCW70-105.210: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). 6. Review of Street Frontage Landscape: a. A mix of hard surfaces, structured planters, and terraces may be incorporated into street frontage landscape buffer where such features would enhance the desired streetscape character for that particular neighborhood: The subject proposal is located adjacent to Maple Valley Highway and Houser Way North. As those areas have sufficient landscaping, staff does not propose any additional landscaping to occur at this time. However, additional internal landscaping as part of the aquatic center development is proposed. This landscaping would mainly consist of ornamental planting areas located within the aquatic park. H. RECOMMENDATION: Staff recommends approval of the City of Renton Aquatic Center Site Plan Review Application, Project File No. LUA-02-147, SA-H, ECF.

The subject site is currently utilized by the City of Renton as the Cedar River Park, which contains the Community Center building, Carco Theater and ball fields. The proposed aquatic center triggers the site plan application referenced above and also requires a parking modification. The applicant has indicated that the subject site currently contains approximately 400 parking stalls, which is 295 spaces short of the minimum number of stalls required for all uses (Community Center building, Carco Theater and the proposed aquatic center use). It should be noted that the subject site, prior to the proposed aquatic center addition, is currently 29 parking stalls short of the minimum required by code. Nevertheless, the applicant has requested a parking modification with the site plan application. Section 4-4-080Fd allows the Planning/Building/Public Works Department to grant modifications from the parking standards for individual cases provided that the modification meets the following criteria (pursuant to RMC 4-9-250D2): a. Will meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment; and b. Will not be injurious to other property(s) in the vicinity; and c. Conforms to the intent and purpose of the Code; and d. Can be shown to be justified and required for the use and situation intended; and e. Will not create adverse impacts to other property(ies) in the vicinity. Background The subject proposal would result in the construction of new outdoor aquatic center. The facility would be comprised of a 9,250 square foot leisure pool, 3,837 square foot lap pool and 6,500 square feet of concession and changing room areas. The property is located in the Center Office Residential (COR) zone and is adjacent to Maple Valley Highway. The site is currently developed with an existing Community Center building, Carco Theater and ball fields, along with supporting utilities, parking, and landscape improvements. Additional parking stalls are not proposed within the Cedar River Park site, thereby increasing the non-conforming parking situation. At present, a total of 400 parking spaces exist within the boundaries of the site. The proposed aquatic center would require an additional 266 parking H:\Division.s\Develop.ser\Dev&plan.ing\PROJ ECTS\02-147.jason\pkgmod.doc - stalls, resulting in a parking stall shortage of 295 parking stalls (266 aquatic center stalls + current 29 parking stall shortage =295). Section 4-4-080F of the parking regulations require the provision of a specified number of parking spaces based on the specific use of the site. Based on the applicant's parking analysis, the Community Center building contains 35,380 square feet of assembly area, which requires 1 stall per 100 square feet(35,380/ 100 = 354 parking stalls). Carco Theater is comprised of 300 theater seats, which requires 1 stall per every 4 seats (300/4 = 75 parking stalls). Finally, the proposed aquatic center consists of approximately 26,600 square feet of pool, building and deck area, which requires 1 stall per 100 square feet (26,600/ 100 = 266 parking stalls). Therefore, the total number of parking stalls required is 695. The following table also depicts the above- mentioned parking requirements: Use/sf Parking Ratio Required Provided Parking Parking Community Center 35,380 sf 1 stall per 100 square feet 354 354 Carco Theater 300 seats 1 stall per every 4 seats 75 46 Aquatic Center 26,600 sf 1 stall per 100 square feet 266 0 Total 695 400 Because the existing number of stalls is 295 spaces less than the minimum number of stalls required by code, the applicant has included a parking modification request with the site plan application. The approval of the parking modification will be required as a condition of approval for the proposed site plan. In the event the modification request is not approved, the applicant would be required to comply with the parking regulations by either modifying the site plan, or by establishing alternative arrangements (e.g., off-site or shared parking through agreements). In addition, the satisfaction of this requirement would be necessary prior to the issuance of building permits. Analysis 1.) Will meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment. The applicant's project design team submitted a narrative statement that compared actual parking demand with existing aquatic centers throughout the area. Specifically, the project team determined that the maximum occupancy load associated with the Renton aquatic center would be below 1,000 individuals. The project team concluded that, on average, each vehicle coming to the Cedar River Park to utilize the aquatic center would have 3.5 people per car. The team also concluded that approximately half of the pool users would be dropped-off by family; thus, not requiring a dedicated parking stall. Therefore, the total number of stalls required for the aquatic center would be approximately 142 (500 [half the maximum occupancy load] /3.5 [individuals per car] = 142 dedicated parking stalls). The project team has determined that the aquatic center peak use hours would be at different times than the Community Center and Carco Theater. Specifically, the project team believes the pool peak use hours would be limited to the weekends and during the first two hours of operation during the week (approximately from 10:00 am to 12:00 pm). The swim teams, exercise classes and seniors would utilize the aquatic center in the early morning hours. However, the Community Center building peak use hours are during the evening on weekdays and afternoon on the weekends. Carco Theater is mainly utilized during the evening hours both during the weekdays and weekends. Therefore, the project team anticipates the 400 existing parking stalls within the Cedar H:\Division.s\Develop.ser\Dev&plan.ing\PROJECTS\02-147.jason\pkg mod.doc River Park to be adequate to accommodate the additional demand generated from the aquatic center use (approximately 142 stalls during peak pool demand). The code's on-site parking requirements are intended to eliminate parking impacts to surrounding properties. During the aquatic center peak parking demand, 142 stalls would be required out of the 400 existing parking stalls. As peak demand for each use (Community Center, Carco Theater and the aquatic center)would not occur at the same time, staff anticipates the existing 400 parking stalls to be adequate for the proposed aquatic center use. Therefore, the requested modification conforms to the intent and purpose of the parking regulations by providing sufficient on-site parking for each use within the site. The proposal, as depicted on the site plan, appears to meet the objectives and safety, function, appearance, environmental protection and maintainability intended by code requirements, based upon sound judgment. 2.) Will not be injurious to other property(s) in the vicinity. The proposed parking satisfies code requirements for stall width, depth, drive aisles, and emergency access. Based on the applicant's parking modification justification, the site would provide adequate parking for the intended use(s). As peak parking demand for the aquatic center use is expected to occur during non-peak parking demand for the other uses within the park, staff does not anticipate a parking shortage at any one-time. As adequate parking for each use during peak parking demand time would be accommodated, patrons are not expected to park off-site. Therefore, staff does not expect this proposal to be injurious to other properties in the vicinity. Finally, it should be noted that the existing parking situation is currently 29 parking stalls short of the minimum required. However, this substandard situation has not been found to be injurious to other properties in the vicinity. Moreover, the project team has indicated that a parking shortage does not exist because the Community Center and Carco Theater have differing peak parking demand hours. The project team concludes that the addition of the aquatic center would also be harmonious with the existing on-site parking, because it too would have a different peak parking demand than the other existing uses. 3.) Conforms to the intent and purpose of the Code. See discussion under criteria number 1)above. 4.) Can be shown to be justified and required for the use and situation intended. As indicated in the applicant's parking justification, the existing 400 parking stalls are rarely maximized as each use within the Cedar River Park has differing peak parking demand times. Therefore, the existing 400 parking stalls provided are justified for the existing and proposed use(s) and situation at the Cedar River Park. 5.) Will not create adverse impacts to other property(ies) in the vicinity. As stated under criteria number 2)above, the proposed parking would not create adverse impacts to other properties in the vicinity from the Cedar River Park. Recommendation The proposed aquatic center use is expected to generate peak parking demands at differing times than the existing uses within the Cedar River site. According to parking code requirements (RMC 4-4-080F10e)for indoor/outdoor recreational facilities, the proposal would need to provide 295 additional parking stalls. However, based on the parking justification provided by the applicant, staff recognizes that the proposed parking for the site would be adequate for the intended use(s)within the Cedar River Park.

Aquifer Protection: 1. See attached Aquifer Protection comments dated January 9, 2003. r r k a #- x ' • CITY OF RENTON PLANNING/BUILDING/PUBLIC WORKS MEMORANDUM DATE: January 9, 2003 TO: Juliana Sitthidet FROM: Carolyn Boatsman SUBJECT: Renton Aquatics Center The following comments are offered with respect to the protection of the City's drinking water aquifer: I. The proposal includes a well to be used to monitor the groundwater level under the pools. It is proposed that the well would also be used to pump down the aquifer should a pool need to be emptied during a period of water tables high enough to float the pools. The Water Utility has doubts that it would be feasible to establish a groundwater capture-zone large enough to protect the pools in this type of aquifer. We suggest that pools not be emptied during high water. Should this aspect of the proposal go forward, the Utility would require review and approval of the plans and specification for the well and pump to ensure that no negative effects on quality or quantity of drinking water would occur. Documentation of compliance with Department of Ecology well construction requirements would also be required. 2. Review of a preliminary compilation of hazardous materials that will be present on the premises indicates that the total will be equivalent to about 125 gallons (solids converted to liquids at the rate of 10 pounds solid to 1 gallon liquid for counting purposes). This amount is below the 500-gallon maximum quantity allowed in Zone 1 of the Aquifer Protection Area (APA). We reserve final comment on the location of this facility when we have an opportunity to review the Hazardous Materials Inventory Statement requested by the Fire Prevention Bureau. Some items that will likely be listed in the HMIS will be exempt for aquifer protection purposes (janitorial and personal care products, aerosol cans, hazardous materials determined to present no risk to the aquifer, etc.). A final determination as to whether an Operating Permit will be required will also be made when we review the HMIS. 3. The construction mitigation narrative submitted with the proposal does not mention compliance with APA Construction Activity Standards (RMC 4-4-03007). The Utility operates production wells in the immediate vicinity of the project and is concerned regarding typical contaminants that can be introduced during construction such as leaky hydraulics, spill of stored chemicals, etc. Documentation of compliance with the standards should be included in plans and specifications. 4. As a reminder, sewage and stormwater piping and appurtenances shall meet APA Zone 1 specifications contained in RMC 4-3-050S. C:\WINDOWS\TEMP\AquaticCeaterEnvReview.doc\st cc.

The site will need security lighting and any construction trailer should be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. Although the freeway is close by, this area of Renton is very isolated, especially during hours of darkness, and susceptible to criminal activity. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" throw when bolted. Glass windows in the trailer should be shatter-resistant. I recommend the developer post appropriate "No Trespassing" signs on the property (in numerous locations) while it's under construction (appropriate verbiage flier attached). This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. The use of off-duty police officers or private security guards to patrol the site during the hours of darkness is highly recommended. The City should continue the security of this property following construction. COMPLETED BUILDING It's important to direct all foot traffic into the main entrance of the aquatic center. This should be monitored during all hours of business by placing a reception/ticket area in the front of the center, with participant access severely restricted. This will assist with control of the pedestrian traffic in the center's public areas. (Entrance through other exterior doors should be strictly prohibited— this includes employees.) Rules of usage should be posted in conspicuous locations throughout the complex. All doors leading to enclosed structures (i.e., changing rooms, bathrooms, concessions, etc.) should be metal with single-latch deadbolts and latch guards with pry-resistant cylinders around the locks. The outside of these doors should be marked as "Alarmed Door" in red, at least 6 inches in height. Any payphones should be posted away from the changing rooms, and set up at out-going only. The fencing around the pools should be enhanced (for security purposes) with razor Page 1 of 2 PRO` CT LUA 02-147, SA-H, EC_ Aquatic Center City of Renton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET (Continuation) or barbed wire. It should not be expected that criminals will not scale this fence, since chain-link fencing provides more then adequate footing for the climb. It's recommended that an alarm system be installed for those structures which are enclosed, at that the sensors include both motion and door/window contacts. For the exposed portion of the aquatic center, there should be an abundance of lighting provided to deter criminals from entering this area after hours. Surveillance cameras are also recommended for this location, with the focus being on the pool area, changing rooms (outside), and pro shop. Landscaping in and around the exterior of the buildings should not be too dense or high. It is important to allow visibility. Too much landscaping will give the center the look of a fortress and possibly give a burglar sufficient coverage to break into the buildings or damage property, especially during the hours of darkness. A business of this size and type needs proper lighting and an abundance of signage. The public needs to be made aware at all times of what space is private and what space is public. Proper No Trespassing signs should be posted in conspicuous locations throughout the outside of the buildings (including parking areas) so enforcement action can be taken if needed. These signs need to have the proper verbiage, which contains the City of Renton Code (see attached.) Page2of2 .,-(11; n Trespass . tau - npt".. l: USINES v Enforcement WATCH Quite often, business owners and managers are faced with crimes that occur on the property after the businesses are closed and the employees have gone home. Some of the crimes that occur are burglary, vandalism, graffiti, trespassing, drug dealing and robbery in the parking lots. There is a way for police and business owners to discourage these types of crimes from taking place on private property, and that is by enforcing the City of Renton's Municipal Trespass Code 6-18-10. In order for police to be able to make an arrest for Trespass, business owners or managers need to purchase signs and display them in conspicuous areas on the property. These signs need to include the following language: 1. Indicate that the subject property is privately owned and; 2. Uninvited presence on the specified property is not permitted during the hours the business is closed, and; 3. Violators will be subject to criminal sanctions pursuant to Renton City Code 6-18-10. MOST IMPORTANTLY -THE SIGNS SHOULD BE CONSPICUOUS FROM ALL POSSIBLE POINTS OF ENTRY TO THE PROPERTY,AND ALSO BE PLACED ON THE EXTERIOR OF THE BUILDINGS. This way when a suspect is arrested, he/she will not be able to claim as a defense that he/she did not know he or she was trespassing. EXAMPLES FOR TRESPASS SIGNS: NO TRESPASSING NO TRESPASSING This is private property. Persons without specific No Trespassing after business hours business are not authorized to be on the premises (insert specific times). Anyone on the between the hours of (insert the hours your business is premises after business hours is subject closed). to arrest and/or citation for Criminal Violators are subject to arrest and/or citation for Trespass and/or impoundment of criminal Trespass pursuant to Renton City Code#6-18- vehicle. Per Renton City Code #6-18- 10.. 10. By enforcing the Trespass Ordinance, business owners and police will be sending a message to criminals that they are not allowed to conduct criminal activity on the property. In making arrests for Trespass, police may be preventing the more serious crimes from taking place.

The proposal includes a well to be used to monitor the groundwater level under the pools. It is proposed that the well would also be used to pump down the aquifer should a pool need to be emptied during a period of water tables high enough to float the pools. The Water Utility has doubts that it would be feasible to establish a groundwater capture-zone large enough to protect the pools in this type of aquifer. We suggest that pools not be emptied during high water. Should this aspect of the proposal go forward, the Utility would require review and approval of the plans and specification for the well and pump to ensure that no negative effects on quality or quantity of drinking water would occur. Documentation of compliance with Department of Ecology well construction requirements would also be required. 2. Review of a preliminary compilation of hazardous materials that will be present on the premises indicates that the total will be equivalent to about 125 gallons (solids converted to liquids at the rate of 10 pounds solid to 1 gallon liquid for counting purposes). This amount is below the 500-gallon maximum quantity allowed in Zone 1 of the Aquifer Protection Area (APA). We reserve final comment on the location of this facility when we have an opportunity to review the Hazardous Materials Inventory Statement requested by the Fire Prevention Bureau. Some items that will likely be listed in the HMIS will be exempt for aquifer protection purposes (janitorial and personal care products, aerosol cans, hazardous materials determined to present no risk to the aquifer, etc.). A final determination as to whether an Operating Permit will be required will also be made when we review the HMIS. 3. The construction mitigation narrative submitted with the proposal does not mention compliance with APA Construction Activity Standards (RMC 4-4-03007). The Utility operates production wells in the immediate vicinity of the project and is concerned regarding typical contaminants that can be introduced during construction such as leaky hydraulics, spill of stored chemicals, etc. Documentation of compliance with the standards should be included in plans and specifications. 4. As a reminder, sewage and stormwater piping and appurtenances shall meet APA Zone 1 specifications contained in RMC 4-3-050S. C:\WRJDOWS\TEMP\AquadcCeaterEnvReview.doc\t cc.

The site will need security lighting and any construction trailer should be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. Although the freeway is close by, this area of Renton is very isolated, especially during hours of darkness, and susceptible to criminal activity. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" throw when bolted. Glass windows in the trailer should be shatter-resistant. I recommend the developer post appropriate "No Trespassing" signs on the property (in numerous locations) while it's under construction (appropriate verbiage flier attached). This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. The use of off-duty police officers or private security guards to patrol the site during the hours of darkness is highly recommended. The City should continue the security of this property following construction. COMPLETED BUILDING It's important to direct all foot traffic into the main entrance of the aquatic center. This should be monitored during all hours of business by placing a reception/ticket area in the front of the center, with participant access severely restricted. This will assist with control of the pedestrian traffic in the center's public areas. (Entrance through other exterior doors should be strictly prohibited— this includes employees.) Rules of usage should be posted in conspicuous locations throughout the complex. All doors leading to enclosed structures (i.e., changing rooms, bathrooms, concessions, etc.) should be metal with single-latch deadbolts and latch guards with pry-resistant cylinders around the locks. The outside of these doors should be marked as "Alarmed Door" in red, at least 6 inches in height. Any payphones should be posted away from the changing rooms, and set up at out-going only. The fencing around the pools should be enhanced (for security purposes) with razor Page 1 of 2 PROJECT LUA 02-147, SA-H, ECr Aquatic Center City of Renton Department of Planning/ Building/ Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET (Continuation) or barbed wire. It should not be expected that criminals will not scale this fence, since chain-link fencing provides more then adequate footing for the climb. It's recommended that an alarm system be installed for those structures which are enclosed, at that the sensors include both motion and door/window contacts. For the exposed portion of the aquatic center, there should be an abundance of lighting provided to deter criminals from entering this area after hours. Surveillance cameras are also recommended for this location, with the focus being on the pool area, changing rooms (outside), and pro shop. Landscaping in and around the exterior of the buildings should not be too dense or high. It is important to allow visibility. Too much landscaping will give the center the look of a fortress and possibly give a burglar sufficient coverage to break into the buildings or damage property, especially during the hours of darkness. A business of this size and type needs proper lighting and an abundance of signage. The public needs to be made aware at all times of what space is private and what space is public. Proper No Trespassing signs should be posted in conspicuous locations throughout the outside of the buildings (including parking areas) so enforcement action can be taken if needed. These signs need to have the proper verbiage, which contains the City of Renton Code (see attached.) Page 2 of 2 Trespass „, Usns Enforcement WATCH Quite often, business owners and managers are faced with crimes that occur on the property after the businesses are closed and the employees have gone home. Some of the crimes that occur are burglary, vandalism, graffiti, trespassing, drug dealing and robbery in the parking lots. There is a way for police and business owners to discourage these types of crimes from taking place on private property, and that is by enforcing the City of Renton's Municipal Trespass Code 6-18-10. In order for police to be able to make an arrest for Trespass, business owners or managers need to purchase signs and display them in conspicuous areas on the property. These signs need to include the following language: 1. Indicate that the subject property is privately owned and; 2. Uninvited presence on the specified property is not permitted during the hours the business is closed, and; 3. Violators will be subject to criminal sanctions pursuant to Renton City Code 6-18-10. MOST IMPORTANTLY • THE SIGNS SHOULD BE CONSPICUOUS FROM ALL POSSIBLE POINTS OF ENTRY TO THE PROPERTY,AND ALSO BE PLACED ON THE EXTERIOR OF THE BUILDINGS. This way when a suspect is arrested, he/she will not be able to claim as a defense that he/she did not know he or she was trespassing. EXAMPLES FOR TRESPASS SIGNS: NO TRESPASSING NO TRESPASSING This is private property. Persons without specific No Trespassing after business hours business are not authorized to be on the premises (insert specific times). Anyone on the between the hours of (insert the hours your business is premises after business hours is subject closed). to arrest and/or citation for Criminal Violators are subject to arrest and/or citation for Trespass and/or impoundment of criminal Trespass pursuant to Renton City Code#6-18- vehicle. Per Renton City Code #6-l 8- 10.. 10. By enforcing the Trespass Ordinance, business owners and police will be sending a message to criminals that they are not allowed to conduct criminal activity on the property. In making arrests for Trespass, police may be preventing the more serious crimes from taking place.

Clarification was also sought at that time as to where ingress and egress from Maple Valley highway was being provided and how pedestrian-oriented circulation was proposed to be handled, especially between the new Aquatics Center and the Community Center complex to the southwest. The applicant has responded in their December 16, 2002 project narrative stating that the current ingress/egress from Maple Valley Highway will remain in effect until access is eventually moved 500 feet to the east when new highway improvements are implemented. No special provisions for pedestrian access are noted. It is apparently assumed that pedestrians, both children and adults, will circulate through the parking aisles between the Community Center and Aquatic Center. The applicants are also requesting a parking modification to reduce the number of required parking spaces. Although the site is relatively isolated by topography and highways/freeways from the rest of the city, the applicant states that they would expect up to half of the users of the new aquatic center to arrive by foot, via skateboards, bicycles, or by auto drop-off. They also believe that for those arriving by auto, the occupancy per vehicle will be an average of 3.5 persons per trip. Recommendation: Continue to support this proposal, again with concerns about the adequacy of pedestrian 4 circulation between facilities as well as the amount of off-street parking proposed for what will essential be a regional outdoor aquatic center. cc: Don Erickson Documentlkl City of Renton Department of Planning/Building/Public Worxs ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET REVIEWING DEPARTMENT: (OV\S �.c�lo r� rU', cs2, COMMENTS DUE: JANUARY 10, 2003 ErcE�Nro� APPLICATION NO: LUA-02-147,SA-H,ECF DATE CIRCULATED: DECEMBER 27,2002 R V E D APPLICANT: City of Renton, Community Services PROJECT MANAGER: Jason Jordan PROJECT TITLE: Aquatic Center WORK ORDER NO: 77077 aEC f ���� LOCATION: 1715 Maple Valley Highway BUILDING prVr�ON SITE AREA: 877,762 sq.ft.

This should be monitored during all hours of business by placing a reception/ticket area in the front of the center, with participant access severely restricted. This will assist with control of the pedestrian traffic in the center's public areas. (Entrance through other exterior doors should be strictly prohibited—this includes employees.) Rules of usage should be posted in conspicuous locations throughout the complex. All doors leading to enclosed structures (i.e., changing rooms,bathrooms, concessions, etc.) should be metal with single-latch deadbolts and latch guards with pry-resistant cylinders around the locks. The outside of these doors should be marked as "Alarmed Door" in red, at least 6 inches in height. Any payphones should be posted away from the changing rooms, and set up at out-going only. The fencing around the pools should be enhanced(for security purposes) with razor Page 1 of 2 PROJECT LUA 02-147, SA-H, ECF Aquatic Center City of Renton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET (Continuation) or barbed wire. It should not be expected that criminals will not scale this fence, since chain-link fencing provides more then adequate footing for the climb. It's recommended that an alarm system be installed for those structures which are enclosed, at that the sensors include both motion and door/window contacts. For the exposed portion of the aquatic center, there should be an abundance of lighting provided to deter criminals from entering this area after hours. Surveillance cameras are also recommended for this location, with the focus being on the pool area, changing rooms (outside), and pro shop. Landscaping in and around the exterior of the buildings should not be too dense or high. It is important to allow visibility. Too much landscaping will give the center the look of a fortress and possibly give a burglar sufficient coverage to break into the buildings or damage property, especially during the hours of darkness. A business of this size and type needs proper lighting and an abundance of signage. The public needs to be made aware at all times of what space is private and what space is public. Proper No Trespassing signs should be posted in conspicuous locations throughout the outside of the buildings (including parking areas) so enforcement action can be taken if needed. These signs need to have the proper verbiage, which contains the City of Renton Code (see attached.) Page 2 of 2 .irli"1 n Trespass ,pwxsA®oee taus 1: USINES ' Enforcement WATCH Animow Quite often, business owners and managers are faced with crimes that occur on the property after the businesses are closed and the employees have gone home. Some of the crimes that occur are burglary, vandalism, graffiti, trespassing, drug dealing and robbery in the parking lots. There is a way for police and business owners to discourage these types of crimes from taking place on private property, and that is by enforcing the City of Renton's Municipal Trespass Code 6-18-10. In order for police to be able to make an arrest for Trespass, business owners or managers need to purchase signs and display them in conspicuous areas on the property. These signs need to include the following language: 1. Indicate that the subject property is privately owned and; 2. Uninvited presence on the specified property is not permitted during the hours the business is closed, and; 3. Violators will be subject to criminal sanctions pursuant to Renton City Code 6-18-10. MOST IMPORTANTLY-THE SIGNS SHOULD BE CONSPICUOUS FROM ALL POSSIBLE POINTS OF ENTRY TO THE PROPERTY,AND ALSO BE PLACED ON THE EXTERIOR OF THE BUILDINGS. This way when a suspect is arrested, he/she will not be able to claim as a defense that he/she did not know he or she was trespassing. EXAMPLES FOR TRESPASS SIGNS: NO TRESPASSING NO TRESPASSING This is private property. Persons without specific No Trespassing after business hours business are not authorized to be on the premises (insert specific times). Anyone on the between the hours of (insert the hours your business is premises after business hours is subject closed). to arrest and/or citation for Criminal Violators are subject to arrest and/or citation for Trespass and/or impoundment of criminal Trespass pursuant to Renton City Code#6-18- vehicle. Per Renton City Code #6-18- 10.. 10. By enforcing the Trespass Ordinance, business owners and police will be sending a message to criminals that they are not allowed to conduct criminal activity on the property. In making arrests for Trespass, police may be preventing the more serious crimes from taking place.

MITIGATION MEASURES maintained to the satisfaction of the representative of the 1. Temporary erosion control measures shallbe p Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. 6. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per square foot of new commercial building area prior to the issuance of building permits. D. ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1. Earth Impacts: A geotechnical report prepared by Associated Earth Sciences, Inc. dated December 2002 was submitted with the project application. The report indicates the site slopes very gently (less than 5%) towards the Cedar River located about 700 to 800 feet to the southwest. The reports states that the subsurface conditions consist of 6-inches of sod and topsoil. Beyond the sod and topsoil, the alluvium consists of silty to clean sand and gravel. In general, the upper horizon of the alluvium was loose to medium dense silty sand. The project area is primarily undeveloped, with a cover of grass and scattered trees, which is currently utilized as a ball field and picnic area. Project excavation would include the installation of the new pools and the building foundations. Preliminary calculations for the project excavation, which may be situated up to eight feet below the existing grade, are approximately 2,800 cubic yards of cut material. Of the 2,800 cubic yards of cut material, approximately 600 cubic yards would be utilized as slope cut backfill. The remaining 2,200 cubic yards will be removed from the project site. In order to ensure potential erosion impacts don't occur during project construction, staff recommends the following mitigation measures: 1) temporary erosion control measures be maintained during project construction; 2) prior to any ercrpt.doc City of Renton P/B/PW Department Enviroi tal Review Committee Staff Report RENTON AQUATIC CENTER LUA-02-147, ECF, SA-H REPORT OF January 21,2002 Page 3 of 5 grading or clearing, install a silt fence along the down slope perimeter of the project area; 3) construct shallow drainage swales to intercept surface water flow and route the flow away from the construction area; 4) the contractor should conduct daily reviews and maintenance of the erosion and sedimentation control measures; 5) provide the Development Services Division with weekly reports on the status and condition of the erosion control plan. Staff anticipates that if these conditions are adhered to as well as existing code previsions, stormwater and erosion control would be adequately mitigated. Mitigation Measures: 1. Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. Nexus: SEPA Environmental Regulations 2. Water—Stormwater/Groundwater Impacts: The applicant has submitted a Drainage Report prepared by Coughlin, Porter and Lundeen, dated December, 2002 with the land use application. The report indicates that the existing storm water collection system across the property is generally a catch basin and piped system. There are no existing detention storage facilities installed on the property. From the area of the new aquatic center, stormwater is piped approximately 1400 feet to an oil-water separator before traveling another 220 feet to a pipe end that discharges directly into the Cedar River. The stormwater analysis indicated that the use of the 1990 King County Surface Water Design Manual is appropriate in this instance. The report states that the water from the proposed pools would drain directly to the sanitary sewer system; therefore, the area of the pools has not been included in either the pre or post developed conditions. Based on those calculations, the report concludes that no additional detention or peak rate run-off control is required for this development. The applicant has proposed to convey stormwater collected from the proposed buildings and decks surrounding the pool via an underground conveyance system. The system would collect stormwater runoff from the pool decks via area drains, while the stormwater collected from the proposed buildings would be collected via downspouts piped to the conveyance system. This system would then tie into an existing catch basin located along the curb at the southwest corner of the site and follow the existing conveyance system, which eventually discharges into the Cedar River. As the applicant's drainage report and construction mitigation plan, as well as existing code provisions adequately mitigate stormwater concerns, staff does not anticipate the need for any additional stormwater mitigation measures. The proposed aquatic center is located within the Aquifer Protection Area Zone One (APA 1), the zone encompassing the City's aquifer recharge areas. In the APA 1 zone, code regulates the type and amount of hazardous materials that can be stored, handled, treated, used and produced on site. Specifically, within APA 1, the maximum amount of chemicals is limited to 500 gallons. In addition, secondary containment is required for all stored chemicals. Since chemical treatment is required for the general maintenance and operation of the aquatic center, the applicant would be required to adhere to the existing APA 1 regulations with regard to chemical usage and storage. ercrpt.doc City of Renton P/B/PW Department Environ al Review Committee Staff Report RENTON AQUATIC CENTER LUA-02-147, ECF, SA-H REPORT OF January 21,2002 Page 4 of 5 The applicant has indicated that the maximum amount of swimming pool chemicals kept on site at any one time would not exceed 200 gallons. In addition, the applicant has proposed to construct a secondary containment system, which would prevent any spills from reaching the ground water. As the existing code provisions adequately mitigate any concerns associated with ground water protection, staff does not recommend any additional mitigation measures. Mitigation Measures: No further mitigation is recommended. Nexus: N/A 3. Fire Protection Impacts: Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the condition that the applicant provide required improvements and fees. As the proposal would add approximately 6,500 square feet of additional building area, staff recommends that the applicant be required to pay a Fire Mitigation Fee in the amount of $0.52 per square foot of new building area. The total fee is estimated at $3,380.00 (6,500 square feet of new commercial buildings x $0.52.00 = $3,380.00). The payment of the fee is required prior to building permit issuance. Mitigation Measures: The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per new square foot of commercial building area prior to the issuance of the building permit. Policy Nexus: SEPA Environmental Regulations; Fire Mitigation Fee Resolution No. 2913, Ordinance 4527. 4. Transportation Impacts: Primary access to the site is proposed via Maple Valley Highway, while secondary access would be from Houser Way North. No new access points or streets are proposed as part of this project. Furthermore, as the site is an existing community park and the proposed project area is currently being utilized as a picnic area, soccer, baseball and football field (recreational), the proposed aquatic center use (recreational) would not trigger any additional traffic impact fees. The applicant has indicated that the aquatic center use would utilize the existing parking areas within the Cedar River Park, which are shared by the Community Center, ball fields and Carco Theater. Currently, there are approximately 400 parking stalls within the Cedar River Park. Staff has reviewed the parking areas and determined that the parking stalls meet current design standards regarding stall width, backout distance and drive aisle width. Therefore, staff recommends that no further traffic mitigation be required. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A E. COMMENTS OF REVIEWING DEPARTMENTS The proposal has been circulated to City Departmental / Divisional Reviewers for their review. Where applicable, these comments have been incorporated into the text of this report as Mitigation Measures and/or Notes to Applicant.

Approval is requested to locate an Aquatic Recreation Center at the Renton Community Center. King County requires that a capacity charge be applied to any project that constructs a new connection to the sewer system, any reconnection within five years of a disconnection, or any change in use or building remodel that includes an increase in plumbing fixtures. King County generally receives notice of new construction; however, some sewer districts and/or the cities that represent them have neglected to report changes in use and tenant improvements that involve an increase in plumbing fixtures. In an attempt to remedy this problem, we are sending this reminder to you in response to the Public Re-Notice of Application. We ask that you forward this reminder to the sewer district or city department responsible for Sewer Use Certification forms: Please be sure that a Non-Residential Sewer Use Certification form for the above project is completed and sent to the King County Capacity Charge Program in a timely manner. The form should be sent to Eunice Verstegen, Capacity Charge Program, KSC-NR-0501, at the address above. If you need additional forms or have questions about the program, please call Eunice at (206) 684-1740. Thank you for the opportunity to review and comment on this proposal.

CITY OF RENTON MEMORANDUM DATE: June 20, 2002 TO: Project Team �— FROM: Jason E. Jord fi, ssociate Planner SUBJECT: Swimming Pool Land Use Permit Timing In order to determine exactly what land use permits are required, Development Services strongly encourages Community Services to submit for a pre- application conference. A pre-application conference could be conducted in one to two weeks and can be initiated by submitting a conceptual site plan and accompanying project narrative. Based on our general knowledge of the project, Planning Staff has determined that the project would require environmental (SEPA) review, a Shoreline Substantial Development Permit and a Hearing Examiner Conditional Use permit. The land use permits would be processed concurrently. The process is expected to take a maximum of 16 weeks, from the time the application is accepted as complete, until the Hearing Examiner issues a decision and the appeal period(s) are complete. In this case, the City would have a project decision within 12 weeks from the date the application is accepted. Planning staff would attempt to run the shoreline permit and conditional use permit appeal periods concurrently, which may eliminate two to four weeks of processing time. In order to have all of the environmental and land use permits processed before the bidding process commences (on or about March 5, 2003), Community Services would need to submit for the land use permits in mid November, 2002. Building permits could be processed concurrently, but could not be issued until the completion of the appeal periods for the land use and shoreline permits. Please contact me at X7219 if I can be of further assistance.

The Aquatics Center will consist of a 9,520 square Steven J.McNutt,AIA gwa y' q q R G.Nelson,AIA feet leisure pool, 3,837 square feet lap pool, and accompanying pool management and changing Benson A.Nielsen,AIA facility of 6,500 square feet. William M.Podobnik,AIA Richard A.Salogga,AIA The project schedule has going out to bid at the end of February, which would set proposed GregoryJ.Stack,AIA beginning of construction some time in April. The substantial completion date is set for December - 19t , 2003. Thomas E Golden,AIA Dana L.Harbaugh,AIA The Aquatic Center will operate approximately from Memorial Dayto Labor Da or later in Brent G.Harding,AIA q p pp y y' Douglas G.Heyamoto,AIA September depending on the seasonal weather. The center is planned to be open every day, with Michoel R.O'Malley,AIA possibly different daily hours of operation from workdays to weekends. The exact hours are GuyJ.Overman,AIA operational issue, but usual hours of operation for facilities of this kind are as follows. The pool William W.Rash,AIA Bruce B.Turner,PE opens between 5:30 to 6:00 a.m. for lap swimmers, which is followed by swimming lessons until about 9:00 or 10:0a.m. Some swimming lessons can be done in the wave pool during the lap pool use hours. General public admission starts usually at late morning hours between 10:00 and 12:00 and continues until 7:00 or 8:00 p.m. The surplus soil from the excavation will be hauled away by the only access to the site, which is from Maple Valley Highway in the immediate vicinity of the Aquatic Center location. From there hailing can continue by main traffic routes, which include immediate access to 1-405 northbound. Building of the proposed facility anticipates only standard construction methods. Dust and air disturbance will be limited to site work and immediate area around. Site work is limited to excavations, grading, paving and modification of landscaped areas. The contractor is anticipated to provide normal control measures for site work. During construction of the project temporary and permanent measures will be installed to minimize sediment laden runoff from discharge into the local waters. These measures include a stabilized construction entrance, interceptor swales, inlet protection and filter fabric fencing. For the period between November 1 through March 1 disturbed areas greater than 5,000 square feet left undisturbed for more than 12 hours must be covered with mulch, sodding, or plastic covering. Finally, all cleared areas will be revegetated after grading is completed. Anticipated hours for hauling soil are within normal construction working hours. Since major freeways are right next to the site no impact is anticipated to the surrounding area. There is no preliminary traffic control plan since the construction is anticipated to take place during the normal construction hours. Due to the relatively small size of the project and the fact that construction related trips will use only main traffic routes during regular working hours traffic impact will be negligible. Please advise if we need to provide more information on the subject. Thank you in advance.

Thomas E.Golden,AIA Dana L.Harbaugh,AIA The exact/proper pool site is a part of larger Cedar River Park, and is located at the Northeast Brent G Harding,AIA corner of the current green fields area. Maple Valley Highway is to its northeast, with residences Douglas G.Heyamoto,AIA across the highway wayupthe hill. Cementplant is to site's southeast, and thepark property is to Michael R.O'Malley,AIA g y p p y GuyJ.Overman,AIA the south, with Cedar River as the boundary about 570 feet away from the curb at the proposed William W.Rash,AIA pool site. Existing zoning designation of the site is COR1. Bruce B.Turner,PE The Cedar River Park is used for sports and recreation, primarily for baseball, softball and soccer, but also picnics and other individual activities. There are no known planned existing improvements, other than the proposed project. The Renton Aquatics Center will be a facility for recreational use, which will complement already existing uses in the park. The pool site is a completely flat site and will remain as such. There are no special site features such as wetlands or other water bodies. Cedar River is about 570 feet away from the curb at the proposed pool site, which is larger than 200 feet shoreline buffer. Site soils generally consist of about 8 to 10 feet of sand and silty sand mapped on the King County Soil Survey by the United States Department of Agriculture Soil Conservation Service (USDA SCS) as Pilchuck Loamy Fine Sand. Clean, free draining gravel underlies the sand below these depths. Enclosed Subsurface Exploration, Geological Hazard, and Preliminary Geotechnical Report prepared for Renton Aquatics Center Project for City of Renton, describes soil conditions in greater detail. As previously mentioned the Renton Aquatics Center will be a facility for primarily recreational use, with possibility for other related uses like swim lessons, therapeutic use of"lazy river" part of the leisure pool, occasional swim meets, etc. The site layout preserves adjacent roads and parking intact, with only necessary accessible and service ramp modifications to the existing road curbs. Therefore the scope of the project is limited to the existing property within the existing green fields area. The only access to the property is from the Maple Valley Highway to the north, at the existing traffic light. That will remain so until the separate project for Male Valley Highway improvements gets constructed, when the entry to the Cedar River Park and the aquatics center will move over 500 feet along the road to the east. That project is independent from proposed Aquatics Center. There are no proposed off-site improvements in the scope of the project. Calculations show that Offices in Seattle,Spokane existing fire hydrants are sufficient to adequately serve the new facility, and the utilities have and Coeur d'Alene capacity to absorb new use. 22015ixth Avenue Suite 1405 The estimated construction cost upon completion of design development phase is around $3.4 Seattle,Washington million. This type of the aquatic center has not been done in this area before, and it is hard to 98121-1832 estimate the fair market value of the new facility.

The majority of on-site soils are suitable for use as structural fill. Approximately 2,200 cubic yards will be hauled from the site. The pool sub-drain system is not anticipated to have any effect on the underground water table. A pool sub-drain monitoring well will be installed to measure the level of groundwater underneath the pools. The groundwater level will need to be monitored when it would be time to empty the pools. If the groundwater level is high and the pools are emptied, there could be buoyancy forces acting on the pools that could actually cause the pools to 'pop' out of the ground. If the water table was high, the groundwater could be pumped down to avoid this potential problem. All pumping of the groundwater would be fully coordinated with the City of Renton. Trees to be removed are (9) 12" caliper Pin Oaks and (1) 3' caliper Big Leaf Maple, which is hollow inside. The Renton Aquatics Center will be a facility for recreational use, which will share parking areas provided for the whole complex, including the Community Center and the Theater. Given the lack of precise code requirements for parking for Community Center and Aquatic Center, and the real life experience regarding the use of these facilities, we have done analysis of the existing conditions and parking requirements for intended uses. Per conclusions of the analysis, we will request a modification based on our understanding of the parking requirements. Please see enclosed letter describing Justification for Parking Modification. Please advise if we need to provide more information on these topics. Thank you in advance.

Since the existing Development Regulations do not have precise code R.G.Nelson,AIA requirements for parkingfor CommunityCenter and Aquatic Center, we have applied the most Benson A.Nielsen,AIA q q PP William M.Podobnik,AlA similar listed uses to determine what would be required number of parking stalls. The parking Richard A.Saloggo,AIA chart is attached and listed as well on the overall site plan on drawing A-2. The Renton Aquatics Gregory J.Stack,AIA Center will be a facility for recreational use, which will share parking areas provided for the whole complex, including the Community Center and the Theater. No existing parking spaces will be Thomas E.Golden,AIA removed by the proposed project. The new construction area is almost completely inside the Dana L Horbaugh,AIA existing road curbs. It is only grass and the existing picnic shelter that will be removed. Presented Brent G.Harding,AIA analysis of the existing conditions and intended use is the reason to ask for Justification for Douglas G.Heyomoto,AIA Modification. Michael R.O'Malley,AIA Guy J.Overman,AIA William W.Rash,AIA It is our experience that most codes do not specifically mention leisure pools when calculating Bruce B.Turner,PE parking requirements. The same is the case with Development Regulations for Renton, Washington. We are often asked what our practical experience tells us to provide. Typically, and at the Renton Aquatic Center, we would expect up to half of the users to arrive on foot, via bicycle, skateboard, or via auto drop-off. This means that the other half will arrive by car and needs to park on site. Our experience suggests that the occupancy of cars averages 3.5 persons per car, since mothers are often bringing a group of children to the pool. These kinds of facilities are also very popular with children and younger teenagers who like to come in groups, but can not drive themselves. Younger teenagers very much like to spend time at the pool with their peers, and not necessarily with their parents being with them. These users need to be dropped off at the facility, and picked up later in the day. Our evaluation of parking available to the whole site shows that there are 400 total paved parking stalls available. The Maple Valley Highway road improvement project, currently under design, will provide 38 new parking stalls that will be used primarily for the pool, and offset loss of parking at the south road edge. Future plans consider relocating the existing maintenance facility located at the North-East corner of the park and converting it to parking, which could provide up to 77 new parking stalls, which would be used almost exclusively for the Aquatic Center. Potential parking improvement in the future could include arranging a parking agreement with the adjacent cement plant. The agreement would describe seasonal use of certain area for relief parking during times not required by the plant. It is not uncommon for pools and other civic or public facilities in the area to arrange agreements of this kind. It is a more efficient use of impervious surfaces and benefits the community at large. Also, the area between the Community Center and 1-405 is currently very much underutilized, and could easily receive parking enlargement for about 25 new stalls. In summary: Existing Spaces 400 Offices in Seattle,Spokane Future: Current Maintenance Facility Site converted to parking 77 and Coeur d'Alene Potential: Area Between 1-405 and Community Center 25 2201Sixth Avenue Suite 1405 Seattle,Washington Agreement with Cement Plant unknown 98121-1832 Total Potential Parking Spaces 502 TEL 206-441-4522 FAX 206-441-7917 nacanwarchco.com www.nwarchco.com • City of Renton, Community Services—Planning Department December 18, 2002 Page: 2 At present parking availability and facility occupancy of fewer than 1,000, it means that less than 150 parking stalls are needed to provide parking for 50% of the pool users, at factor of 3.5 people per car. If all future potential parking gets built, the pool will have about 100 new adjacent parking stalls available for its use. At a 3.5 factor this could provide for about 350 additional occupants arriving and parking their car. That means that if less than half of existing parking is occupied by the pool users, eventually 100% of pool occupants could have nearby pool specific parking stalls. However, the experience shows that such extent of parking availability is not needed on the regular basis. It is the occasional days when something extremely attractive is happening elsewhere in the park (old cars show, etc), which brings large number of individual visitors, that the additional parking will serve as a relief. The anticipated pool peak hours for parking are on weekends, and during the first two hours the pool is open for public use. The exact time is an operational issue, but it can be assumed that it will happen somewhere from 10-12 in the morning. The pool will typically be used by swim teams, aerobics, therapeutical use for seniors, etc. in the early morning hours. This is not the same as the anticipated peak hours for the Community Center, which are during Saturday afternoon. A wedding reception party of 300 would need to use 120 parking stalls at the conservative factor of 2.5 persons per car. That would leave about 280 current stalls for non-wedding uses. If 80 more spaces get used for other uses at the community center and the sport fields that would leave 200 stalls for afternoon pool use, which provides for 700 users using a 3.5 factor for all users. Theater peak hours are usually in the evening and are not assumed to overlap with the pool peak hours. From the explained analysis our design team has concluded that there is enough paved parking presently on site for regular pool operations. The potential future parking will just come in handy for the occasional days of special events at the park. Therefore we believe that modification is justified, since it complies with modification criteria. a) The existing parking that will be available for the Aquatic Center meets functional, appearance, safety, environmental protection, maintainability and overall Code requirements. b) The available parking is not injurious to other properties in the vicinity. c) Design and location of available parking conforms to the intent and purpose of the Code d) Presented analysis shows that the modification is justified and required for intended use. e) There are no properties in the vicinity that would be adversely impacted by this modification.

C VO 12. Location of the proposal. Give sufficient information for a person C O- Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT to understand the precise location of your proposed project, including a street address, if any, and section, township and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographical map, if reasonable available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The site is located at the North-East corner of the field area of the Cedar River Park. It is bounded on the north by the Maple Valley Highway, the current entry/ service road for the Community Center to the east, existing parking to the south and soccer and baseball fields to the west. B ENVIRONMENTAL ELEMENTS 1 Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other. b. What is the steepest slope on the site (approximate percent slope)? Less than 2%. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat muck)? If you know the classification of agriculture soils, specify them and note any prime farmland. The Geotechnical Report describes the site soils as "Site soils generally consist of about 8 to 10 feet of sand and silty sand mapped on the King County Soil Survey by the United States Department of Agriculture Soil Conservation Service(USDA SCS) as Pilchuck Loamy Fine Sand. Clean, free-draining gravel underlies the sand below these depths. d. Are there surfaces indications or history of unstable soils in the immediate vicinity? If so, describe. The near-surface sandy soils are in a loose condition, and are subject to post- construction foundation settlement if foundations are placed directly on these soils without prior remediation.No other unstable soils were encountered. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Excavation will be performed for the installation of the new pools and building foundations. Preliminary calculations for the pool excavation that could be up to 8 feet below the existing grade are about 2,800 cubic yards of excavation with about 600 cubic yards being stockpiled and reused as slope cut backfill. The majority of on-site soils are suitable for use as structural fill. Approximately 2,200 cubic yards will be hauled from the site. f. Could erosion occur as a result of clearing, construction or use? If so, generally describe. No. Pools required excavations will require only standard construction pool walls support. The near-surface sandy soils will be moderately erosion-sensitive when exposed to surface water or high winds given their relatively small grain size and moisture sensitivity.Therefore,during clearing and grading operations,these soils will require erosion protection measures as discussed below. Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? 38%of the whole site. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any? Erosion control measures are as follow: 1) All storm water from impermeable surfaces should be tightlined into approved storm water drainage systems or temporary storage facilities. 2) To reduce the amount of soil transport, silt fences should be placed along the site perimeter. 3) Construction should proceed during the drier periods of the year if possible and disturbed areas should be revegetated as soon as possible. 4) Soils to be reused around the site should be stored in such manner as to reduce erosion. Protective measures may include,but are not necessarily limited to, covering with plastic sheeting, or the use of straw bales/silt fences. 2. Air a. What types of emissions to the air would result from the proposal (i.e. dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. A small amount of dust from construction mainly during the summer months in 2003 and exhaust from contractor vehicles and equipment b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No c. Proposed measures to reduce or control emissions or other impacts to air, if any: Normal construction dust control measures for site work. 3. Water a. Surface 1. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal steams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. No. Cedar River is about 570 feet away from the closest road curb, which is greater than the 200 feet shoreline buffer required. 2. Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. No 3. Estimate the amount of fill and dredge material that would Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material N/A 4. Will the proposal require surface water withdrawals or diversions? Give the general description, purpose, and approximate quantities if known. No 5. Does the proposal lie within a 100 year floodplain? If so, note location on the site plan. No. 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground 1. Will ground water be withdrawn or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No 2. Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agriculture; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. N/A c. Water Runoff(including storm water): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. Rainfall will be collected in on site storm system and conveyed to existing city storm system. 2. Could waste materials enter ground or surface waters? If so, generally describe. Water treatment chemicals for pool maintenance will be stored on site but will meet all the requirements of an Aquifer Protection Area (Zone 1). There also are no new pollution generated surfaces proposed for the site. Therefore,negligible waste materials will enter ground or surface waters. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: The proposed development will have little new impervious area,and as such the increase in surface runoff will be negligent. Water from the swimming pools will be directed to the sanitary sewer system. Surface water runoff will be discharged in the natural pre-developed location,and will have • Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT insignificant impact on the downstream system. 4.

Project Proposal: The subject site is located at the Cedar River Park, between Interstate 405 and the Maple Valley Highway. The property is currently developed as a community park with a community center and theater. The Cedar River is located directly south of the park site. The project proposal is to construct two separate swimming pools, which would consist of a 25-yard, 6-lane lap pool and a 9,000 square foot leisure pool. The leisure pool would consist of a wave pool area, a quite pool play area and a lazy river with water slides. Zoning: The subject site is designated Center Office Residential (COR) on the City's Zoning and Comprehensive Plan Map. The purpose of the Center Office Residential land use designation is to provide for a mix of intensive office, hotel and convention center and residential activities in a high- quality, master planned development,that is integrated with the natural environment. Development Standards: The proposal would need to comply with the COR zone development standards and other associated regulations as addressed below: 4- 1 Lot Coverage - The COR zone allows building coverage at a maximum of 65% of the lot area for ee4iq projects not providing structured parking, or 75% if parking is provided within the building. The / proposed aquatic center is not expected to increase lot coverage within the existing development beyond what the development standards allow. Setbacks — Setbacks are measured from the property lines to the nearest point of the structure. The 1 required setbacks in the COR zone are determined through the site plan review process. In this case, staff generally supports the proposed aquatic center location; however, the formal site plan a review submittal would need to be more detailed in order to provide exact setback measurements. )011/1 Freeway Frontage Setback: -The minimum freeway frontage setback (along Interstate 405 and Maple iValley Highway) is 10 feet of landscaped area. t Height — The COR zone permits a maximum building height of 10 stories and/or 125 feet. The information provided did not indicate the proposed building height. Building height is measured from (plt, the mid-point of a pitched roof to the average finished grade and must be clearly indicated in the plans submitted for the building permit application. 1 Screening—Outdoor storage is not permitted in the COR zone. Outdoor loading, repair, maintenance or work areas, if any, must be screened from adjacent or abutting residential properties with a fence, Renton Aquatic Center Pre-Applicatick,, ,,,,deting File No. Pre-02-095 November 14,2002 Page 2 of 2 landscaping, landscaped berm, or combination thereof. All surface-mounted utility or mechanical equipment and rooftop equipment must be screened from public view. The provision of adequate screening will be carefully considered during the building permit review process, especially with regard to potential noise impacts from the drive through proposed to the rear of the building immediately adjacent to the residentially zoned property. Dumpsters — Screening must also be provided for all garbage dumpsters and recyclable areas pursuant to RMC section 4-4-09007. Dumpsters are not permitted within required setback areas, as well as within 50 feet of a residentially zoned property. In addition, approval of the proposed locations of dumpster areas by Rainier Waste Management is recommended prior to the submittal of the formal land use application. The building permit application 9 will need to include elevations and details on the proposed methods of screening. --Pedestrian Access — A pedestrian connection is required to be provided from the public entrances of the aquatic center to the street frontages and parking areas. The information submitted did not include how pedestrian access would be provided. it Parking/Circulation — The parking regulations require a specific number of spaces based on the i ' amount of square footage dedicated to certain uses. In this case, all the uses on the site would be reviewed as part of the site plan review process. The existing community center and the proposed Cife aquatic center would be required to provide parking at a ratio of 1 parking stall per 5Q% of the maximum occupancy load as established by the Building Code. The theater is required to provide 1 parking stall per every 4 fixed seats or 1 for each 100 square feet of auditorium area. A required parking and provided parking analysis would need to be submitted with the formal site plan review application. In the event, the subject site is under parked, an administrative parking modification would be required. Signage: Only one freestanding business sign (pole, monument/ground, projecting or roof) is permitted per street frontage for each individual parcel. Each sign shall not exceed an area greater than one and one-half square feet for each lineal foot of property frontage that is occupied by the business. In no case shall the sign exceed a total of 300 square feet (150 square feet per face if a two face sign). Pole signs are limited to the maximum height specified in the zone, or a maximum of 40 feet, whichever is less and must comply with the setback requirements of the zone. In addition to the permitted freestanding sign, wall signs with a copy area not exceeding 20% of the facade to which it is applied is also permitted. Environmental Issues: While the proposed aquatic center is located near the Cedar River, it appears all construction would be located beyond 200 feet of the Cedar River Ordinary High Water Mark (OHWM). Therefore, the project would not require a shoreline substantial development permit. No other environmentally sensitive areas were identified within the project site. Permit Requirements: The proposal would require Environmental (SEPA) Review and City Council Site Plan Approval. It should be noted that as the project is located in a COR zone, City staff would make a recommendation to the City's Hearing Examiner,who would then make a final recommendation to the City Council. The City Council would issue the final approval for the project. The review process would be completed in an estimated time frame of 12 to 16 weeks once a complete application is accepted and assuming no appeals are filed. The application fee would be $2,500.00, plus $0.37 per mailing label required for notification to all property owners within 300 feet of the site. In addition to the required land use permits, separate construction, building, and sign permits would be required. The review of these permits may occur concurrently with the review of the land use permits, but can not be issued prior to the completion of any required appeal periods. cc: Jennifer Henning Pre02-095(aquatic center in cor zone with site plan review).doc\ I CITY OF RENTON ECONOMIC DEVELOPMENT NEIGHBORHOODS, AND STRATEGIC PLANNING MEMORANDUM DATE: November 7,2002 JEVELOPMENT PLANNING CITY OF RENTON TO: Jason Jordan NOV 9 FROM: RebecEaLnd RECEIVED STAFF CONTACT: Don Erickson SUBJECT: Cedar River Park Aquatics Center, PRE 02-095 • The applicant, the City of Renton Community Services Department, is proposing the development of an aquatic center in Cedar River Park. The proposed facility would be located northeast of the existing Community Center building near Maple Valley Highway at the north end of the existing main parking lot. The proposed new facility has been sited over a portion of the existing access road from Maple Valley Highway making it unclear how future ingress and egress between the Maple Valley Highway and the park will be provided. The subject site is designated Center Office Residential on the Comprehensive Plan Land Use Map and is zoned COR. Comprehensive Plan policies are listed below. Relevant Comprehensive Plan Land Use Policies: Policy L U-130. A public review process should be required for proposed development plans of each parcel with separate ownership or abutting parcels of the same ownership within the Center. Policy LU-132. Site plans and proposed structures should be designed so as to fully integrate signage, building height, bulk setbacks, landscaping, and parking considerations across the various components of each proposed development. jPolicy LU-133. Internal site circulation should be primarily pedestrian oriented. Objective LU-HH: Site and design municipal facilities to provide the most efficient and convenient service for people while minimizing the adverse impacts on surrounding uses. Policy LU-243. Siting of regional facilities which are specialized or serve a limited segment of the population should rely more strongly on the special locational needs of the facility and the compatibility of the facility with surrounding uses. Policy LU0346. The park system should include neighborhood, community, and regional parks with sufficient acreage and facilities to meet standards adopted by the Renton Parks Commission. Cedar River Park Aquatics Center 2 11/07/02 Policy LU-351. Existing parks should be more intensely developed to provide needed recreation facilities where feasible. Analysis: The proposed new Aquatic Center appears to comply with most of the above land use policies. It will be important to ensure that its design and siting are compatible with other municipal facilities such as the Community Center and Carco Theater already in Cedar River Park (Policy LU-243). Consideration should also be given to creating a clearly delineated pedestrian walkway between the new center and the existing Community Center complex to the southwest (Policy LU-133). The proposed intensification of uses within the Cedar River Park would also appear to be consistent with Policy LU-351. Recommendation: • Support the current proposal while seeking additional clarification on how and where future ingress and egress from Maple Valley Highway will be provided as well as what provisions are being made for pedestrian-oriented circulation between the new Aquatics Center and the Community Center complex to the southwest.

The design for the Renton Aquatic Center is based on the requirements set forth in the 1990 King County Surface Water Design Manual (KCSWDM). The Renton Aquatic Center,located near the intersection of SE Maple Valley Highway(SR 169)and Bronson Way N in Renton,WA(see Figure 1)and is located in an incorporated area on the King County Flow Control Applications Map. The approximately 1.6-acre site is in the Cedar Main Urban Basin plan. The project site slopes very gently towards the Cedar River located about 700 to feet to the southwest. The site was last developed in the late 1980's prior to any County code requirements that addressed the detention of storm water for flow control. The City of Renton is constructing a new Aquatic Center on the 20-acre Renton Community Center property in an area that is primarily undeveloped with lawn and scattered trees. The development would include a six-lane lap pool,several activity pools,a picnic area and building to support changing rooms,restrooms, concessions,and mechanical equipment. The majority of the site area(approximately 250 feet by 310 feet) will be either hard-surfaced or landscaped with grass. Existing Drainage System This entire Renton Community Center property is approximately 20-acres and is developed with impervious areas including buildings,parking lots,and sidewalks. The remainder of the site is predominantly landscaped areas including grass playfields. The existing storm water collection system across the property is generally a catch basin and piped system. There is no existing detention storage facilities installed on the property. From the area of the new Aquatic Center,stormwater is piped approximately 1400 feet to an oil- water separator before traveling another 220 feet to a pipe end that discharges directly into the Cedar River. Proposed Drainage System Stormwater improvement requirements for the site fall within the incorporated area of the City of Renton and the 1990 King County Surface Water Design Manual(KCSWDM). To determine if detention is required for the new development,calculations were performed using the Santa Barbara Unit Hydrograph(SBUH) method. It should be noted that since the water from the proposed pools drains directly to the sanitary sewer system,the area of run-off for the pools have not be included in either the pre or post developed conditions which results in a more conservative analysis. The pools will maintain a water level at least four inches below the surrounding deck surface to prevent any spillover during a significant rainfall event. Modeling both the existing and proposed conditions for the 100-year,24-hour storm event,there is a net increase of discharge from the site of 0.39 cfs(0.89 cfs post-dev-0.50 cfs pre-dev)after development. The project falls under the exemption from on-site peak rate runoff control(1990 KCSWDM#1.2.3)that states if: "The proposed project site post-development peak run-off rate for the 100-year,24-hour duration design storm event is calculated for each discharge location to be less than 0.5 cfs more than the peak runoff rate for the existing conditions" Therefore,no detention or peak rate run-off control is required for the new development. COUGHLINPORTERLUNDEEN Renton Aquatic Center 1 To convey stormwater from the site,a conveyance system will be installed including several area drains connected by piping. Building roof downspouts will be piped directly to the new conveyance piping. This system will then tie into an existing catch basin located along the curb at the southwest corner of the site and follow the existing conveyance system eventually discharging to the Cedar River. There will be no new pollution generating surfaces including such items as metal roofing and asphalt/concrete paving areas for the site,therefore water quality improvements will not be required. There will be some chemicals for the treatment of pool water that will be stored on the site in chemical storage that will meet with all the requirements of the Aquifer Protection Area(Zone 1)requirements including a limit of 500 gallons of materials and a containment dike surrounding the covered storage areas. Temporary Erosion and Sediment Control During construction of the project temporary and permanent measures will be installed to minimize sediment laden runoff from discharge into the local waters. This measures include a stabilized construction entrance,interceptor swales,inlet protection and filter fabric fencing. For the period between November 1 through March 1 disturbed areas greater than 5,000 square feet left undisturbed for more than 12 hours must be covered with mulch,sodding,or plastic covering. Finally,all cleared areas will be revegetated after grading is completed. Summary Stormwater improvements include a new conveyance system with roof downspouts that will connect to the existing on-site system. Per the 1990 KCSWDM exception#1.2.3,no additional detention will be required for the project because there is a less than 0.5 cfs increase in the runoff rate for the 100-year,24-hour storm event between existing and proposed conditions. Also,since there are no new pollutions generating surfaces, stormwater quality control improvements are not required. COUGHLINPORTERLUNDEEN Renton Aquatic Center 2 II.CONDITIONS AND REQUIREMENTS SUMMARY This section addresses the requirements set forth by the Core and Special Requirements listed in Chapter 1 of the 1990 KCSWDM. King County Surface Water Management Design Manual Core Requirements: 1. Discharge at a natural location(1.2.1): All developed flows will be discharged at their natural locations. 2. Off-site Analysis(1.2.2): A preliminary Level 1 downstream analysis has been performed. 3. Runoff Control(1.2.3): A. Peak Rate Runoff Control:Modeling both the existing and proposed conditions for the 100-year,24- hour storm event,there is a net increase of discharge from the site of 0.39 cfs(0.89 cfs post-dev-0.50 cfs pre-dev)after development. The project falls under the exemption from on-site peak rate runoff control that states if 'the proposed project site post-development peak run-off rate for the 100-year,24-hour duration design storm event is calculated for each discharge location to be less than 0.5 cfs more than the peak runoff rate for the existing conditions.' Therefore,no detention or peak rate run-off control is required for the new development B. Biofiltration:Basic water quality is not required for this site. No new pollution generated surfaces will be added. 4. Conveyance System(1.2.4): Existing conveyance facilities will remain. This proposed project will incorporate an on-site conveyance system that will connect downstream into the existing storm system. The increase in discharge flows is insignificant and will not affect the downstream conveyance system. The proposed conveyance system will be sized to convey up to the 25 year storm event. 5. Temporary Erosion and Sedimentation Control(1.2.5): The project is installing sediment control measures as required to address the specific conditions at the site. fi COUGHLINPORTERLUNDEEN , Renton Aquatic Center 3 King County Surface Water Management Design Manual Special Requirements: 1. Critical Drainage Areas(1.3.1): This project is located in the Cedar River Drainage Basin and will comply with any requirements the basin plan may impose. 2. Compliance with an Existing Master Drainage Plan(1.3.2): The project does not require a master drainage plan. 3. Conditions requiring a Master Drainage Plan (1.3.3): The project does not require a master drainage plan. 4. Adopted Basin or Community Plans(1.3.4): The project does not lie within an area with an adopted Basin or Community Plan 5. Special Water Quality Controls(1.3.5): The proposed project will not contain more than one acre of impervious surface that will be subject to vehicular use or storage of chemicals and does not require water quality control. Project Specific Requirements: This site does not abut a Class 1 or Class 2 stream that has an existing flood protection facility and is exempt from this requirement.This site is not required to provide any additional source control. COUGHLINPORTERLUNDEEN Renton Aquatic Center 4 IIL OFF-SITE,ANALYSIS Task 1— Study Area Definition and Maps As-built plans for the Renton Community Recreation Center dated August 1989 were reviewed for an evaluation of the existing conveyance and drainage systems. Task 2-Resource Review a) Basin Reconnaissance Summary Reports: The reports did not indicate any conveyance problems. b) Critical Drainage Area Maps: The site is not within Critical Drainage Area c) Floodplain/floodway(FEMA)Maps: Site is not within a FEMA designated area,see Figure 3 d) King County Soils Survey: Soils map,see Figure 4 e) Wetland Inventory Maps: See Sensitive Areas Maps,Figure 3 f) Sensitive Areas Folio: Site is not within any sensitive areas,see Figure 3 Task 3-Field Inspection One site visit has been made to the site to gather information to be used in the Level 1 Downstream Analysis and off-site conveyance system inspection. Task 4-Drainage System Description and Problem Descriptions We did not observe any off-site conditions or problems that would affect or that would be affected by the on- site storm drainage system. Upstream Analysis The site does not have any off-site areas contributing directly to on-site runoff. There are permanent drainage systems located in Maple Valley Highway(SR 169)and the private access drive southeast of the site that intercept and route drainage around the site. Downstream Analysis The existing stormwater collection system throughout the Renton Community Recreation Center is generally a catch basin and piped system. There is no existing detention storage facilities installed on the property. From the area of the new Aquatic Center,the proposed storm water conveyance system connects to an existing curb line catch basin southwest of the new site. From the new connection point through the existing system,the storm water travels 30 feet southeast in a existing 12-inch line before traveling approximately 360 feet west in series of 12-inch lines. The system travels approximately 210 feet north in a series of 12"lines before traveling about 400 feet west in a series of 15-inch pipes. The storm water then travels 350 feet southwest in a 15-inch pipe series before reaching a gravity oil/water separator housed in a 72-inch manhole with baffles. From the oil/water separator the storm water travels 250 more feet southwest before discharging directly into the Cedar River. The pipe outlet into the river is a 12-inch line with a flapper valve. The pipe end penetrates a stone wall with the pipe invert approximately 12 feet below the top of wall. COUGHLINPORTERLUNDEEN , Renton Aquatic Center 5 Task 5-Mitigation of Existing or Potential Problems There are no existing flooding or erosion problems presently on the Renton Community Center property. The new Renton Aquatic Center results in an insignificant addition of impervious area to the overall property. Therefore,there will not be any potential flooding or erosion problems created by the project.

PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration, geologic hazard, and preliminary geotechnical engineering study for the proposed Renton Aquatic Center. The proposed facility will be located near the existing City of Renton Community Center southeast of the intersection of SR-169 and I-405, in Renton Washington as shown on the Vicinity Map, Figure 1. Our recommendations are preliminary in that site grading information and construction details have not been finalized at the time of this report. The approximate locations of the explorations accomplished for this study are presented on the Site and Exploration Plan, Figure 2. The site features shown on Figure 2 are based on a site plan provided by Coughlin Porter Lundeen (CPL). In the event that any changes in the nature, design, or location of the structures is planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. 1.1 Purpose and Scope The purpose of this study was to provide subsurface data to be utilized in the preliminary design and development of the above-referenced project. Our study included a review of available literature, excavation of exploration borings, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments, and ground water conditions. Geologic hazard evaluations and engineering studies were also conducted to determine suitable geologic hazard mitigation techniques, the type of suitable foundation, allowable bearing pressures, anticipated settlements, basement/retaining wall lateral pressures, floor support recommendations, and drainage considerations. This report summarizes our current fieldwork and offers development recommendations based on our present understanding of the project. 1.2 Authorization Written authorization to proceed with this study was granted by the City of Renton on November 7, 2002. Our study was accomplished in general accordance with our scope of work letter dated October 25, 2002. This report has been prepared for the exclusive use of the City of Renton and their agents, for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, express or implied, is made. Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner. December 2, 2002 ASSOCIATED EARTH SCIENCES,INC. SGB/Ib-KE02672A3-Projects12002672IK£I WP-W2K Page 1 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Project and Site Conditions 2.0 PROJECT AND SITE DESCRIPTION This report was completed with an understanding of the project based on a site plan provided by CPL dated October 2, 2002, a site reconnaissance, and our familiarity with previous geotechnical work performed in the site area. We completed a subsurface exploration program consisting of two exploration borings on November 11, 2002. We understand the City of Renton intends upon constructing a new aquatic center adjacent to the existing community center. The area proposed for construction would measure some 350 feet by 250 feet in plan dimension. The development would include a six-lane lap pool, a kiddy pool, water slides, wave pool, and picnic area, as well as buildings to support changing rooms, restrooms, concessions, and mechanical equipment. The majority of the area would be hard-surfaced or landscaped with grass. The project area is primarily undeveloped, with a cover of grass and scattered trees. A covered picnic area and restroom facility is located on the northeast portion of the proposed development area. The site slopes very gently towards the Cedar River located about 700 to 800 feet to the southwest. The property is surrounded by light commercial properties. Site access is from SR-169, also know as the Maple Valley Highway. 3.0 SUBSURFACE EXPLORATION Associated Earth Sciences, Inc. (AESI) performed a subsurface exploration of the site on November 11, 2002. Our field study included advancing five exploration borings to gain subsurface information about the site. A ground water monitoring well (piezometer) was installed in one of the borings to record future ground water measurements. The various types of soils, as well as the depths where characteristics of the soils changed, are indicated on the exploration logs presented in the Appendix. The depths indicated on the logs where conditions changed represent gradational variations between soil types in the field. Our explorations were approximately located in the field by measuring from known site features and are shown on Figure 2. The conclusions and recommendations presented in this report are based, in part, on the five exploration borings completed for this study. The number, location, and depth of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions between field explorations is necessary. It should be noted that differing subsurface conditions may be present due to the random nature of deposition and the alteration of topography by past grading and/or filling. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific recommendations in this report and make appropriate changes. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/!b-KE02672A3-Prof ects12002672IKEIWP-W2K Page 2 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Project and Site Conditions 3.1 Exploration Borings Exploration borings were advanced with a Mobile B53 track-mounted drill rig. The borings permitted limited visual observation of subsurface conditions. Representative samples of the soils encountered were obtained from the borings using a Standard Penetration Test (SPT) sampler. The SPT sampler obtains disturbed samples and was driven into the soil using a 140- pound hammer free-falling 30 inches. The number of blows required to drive the sampler the last 12 inches is recorded on the boring logs. Materials encountered in the exploration borings were studied and classified in the field by a geotechnical engineer from our firm. All exploration borings were sealed with bentonite and cement immediately after examination and logging. Selected samples were then transported to our laboratory for further visual classification and testing, as necessary. The boring logs have been attached to this report as an Appendix. 4.0 SUBSURFACE CONDITIONS Subsurface conditions at the project site were inferred from the field explorations completed for this study, visual reconnaissance of the site, and review of applicable geologic literature. As shown on the field logs, the exploration borings generally encountered up to 6 inches of sod and topsoil, overlying natural deposits of Quaternary alluvium. The alluvium consists of silty to clean sand and gravel. In general, the upper horizon of the alluvium was loose to medium dense silty sand. With depth, the alluvium graded to medium dense to dense, clean sandy gravel. The top of the dense alluvium varied from 1 foot in EB-1 and EB-4 to about 10 feet in the other borings. This bearing depth is shown in parentheses on Figure 2. The soil conditions encountered in our explorations are consistent with the published geologic mapping of the area. In particular, we reviewed the Geologic Map of Renton Quadrangle. King County, Washington, prepared by D.R. Mullineaux, 1965. This publication shows the project site underlain by Quaternary alluvium consisting of fine-grained floodplain deposits over coarser-grained river channel deposits. 4.1 Hydrology We did not encounter ground water in any exploration borings at the time of our study. However, very moist and oxidized soil occurred below 10 feet in EB-4 and EB-5. Given the site's close proximity to the Cedar River and the relatively dry climatic conditions in the Puget Sound Region over the past year, we elected to install a piezometer in EB-5, although ground water was not encountered within the upper 20 feet of the ground surface. Ground water at this site represents unconfined aquifer conditions common to alluvial plain deposits. Ground water elevations may rise significantly following extended periods of wet weather. We will monitor the piezometer occasionally over the upcoming winter months to evaluate ground water level fluctuations. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC.

GEOLOGIC HAZARDS AND MITIGATIONS The following discussion of potential geologic hazards is based on the geologic conditions as observed and discussed herein. 5.0 SLOPE STABILITY HAZARDS AND RECOMMENDED MITIGATION There are no steep slopes within the immediate project vicinity. Consequently, the risk of earth movement on the subject property is low due to the site's relatively flat topography. 6.0 SEISMIC HAZARDS AND RECOMMENDED MITIGATION Earthquakes occur in the Puget Sound Lowland with great regularity. The vast majority of these events are small and are usually not felt by people. However, large earthquakes do occur as evidenced by the most recent 6.8-magnitude event on February 28, 2001 near Olympia Washington, the 1965, 6.5-magnitude event, and the 1949, 7.2-magnitude event. The 1949 earthquake appears to have been the largest in this area during recorded history. Evaluation of return rates indicates that an earthquake of the magnitude between 5.5 and 6.0 is likely within a given 20-year period. Generally, there are four types of potential geologic hazards associated with large seismic events: 1) surficial ground rupture; 2) seismically induced landslides; 3) liquefaction; and 4) ground motion. The potential for each of these hazards to adversely impact the proposed project is discussed below. 6.1 Surficial Ground Rupture The nearest known fault trace to the project site is the Seattle Fault. Recent studies by the U.S. Geological Survey (e.g., Johnson et al., 1994, Origin and Evolution of the Seattle Fault and Seattle Basin, Washington, Geology, v. 22, pp. 71-74; and Johnson et al., 1999, Active Tectonics of the Seattle Fault and Central Puget Sound Washington — Implications for Earthquake Hazards, Geological Society of America Bulletin, July 1999, v. 111, n. 7, pp. 1042-1053) have provided evidence of surficial ground rupture along a northern splay of the Seattle Fault. The recognition of this fault splay is relatively new and data pertaining to it are limited with the studies still ongoing. According to the U.S. Geological Survey studies, the latest movement of this fault was about 1,100 years ago when about 20 feet of surficial displacement took place. This displacement can presently be seen in the form of raised, wave- cut beach terraces along Alki Point in West Seattle and Restoration Point at the south end of Bainbridge Island. The recurrence interval of movement along these fault systems is still unknown, although it is hypothesized to be in excess of several thousand years. Due to the December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projecrs120026721KEIWP-W2K Page 4 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Geologic Hazards and Mitigations suspected long recurrence interval, the potential for surficial ground rupture is considered to be low during the expected life of the proposed structure. 6.2 Seismically Induced Landslides There are no steep slopes within the immediate project vicinity. Consequently, the risk of seismically induced landsliding on the subject property is low due to the site's relatively flat topography. 6.3 Liquefaction Under the present ground water conditions, the encountered stratigraphy has a low potential for liquefaction due to the dense condition of the gravel and the depth to ground water exceeding 20 feet. However, following extended periods of extremely high precipitation, ground water could rise to within 10 or 15 feet of the ground surface, or even higher during flooding events. The risk of liquefaction would increase if foundations were to be placed on the loose upper sandy alluvium. The risk to the structures could be mitigated by founding them on the lower dense gravel or replacing the upper loose material with compacted structural fill, or rock beneath the footings. Short aggregate pier foundations would also mitigate the liquefaction risk. 6.4 Ground Motion The project site is located within a Zone 3 rating for seismic activity on a scale of 1 (lowest) to 4 (highest) based on the Seismic Zone Map of the United States, Figure No. 16-2 in the 1997 edition of the Uniform Building Code (UBC). This zonation is based on past earthquake activity in the Puget Sound region. As such, design recommendations in the report accommodate the possible effect of seismic activity in areas with a Zone 3 rating, corresponding to a peak ground acceleration of 0.3g (a Richter magnitude 7.5 earthquake occurring directly beneath the site), in accordance with UBC guidelines, using soil type SD. 7.0 EROSION HAZARDS AND MITIGATION To mitigate and reduce the erosion hazard potential and off-site soil transport, we recommend the following: 1) All storm water from impermeable surfaces should be tightlined into an approved storm water drainage system or temporary storage facilities. 2) To reduce the amount of soil transport, silt fences should be placed along the site margins. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/Ib-KEO2672A3-Projects13002672IKEIWP-W3K Page 5 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Geologic Hazards and Mitigations 3) Construction should proceed during the drier periods of the year and disturbed areas should be revegetated as soon as possible. 4) Soils to be reused around the site should be stored in such manner as to reduce erosion. Protective measures may include, but are not necessarily limited to, covering with plastic sheeting, or the use of straw bales/silt fences. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projects120026721KEIWP-W2K Page 6 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations III. PRELIMINARY DESIGN RECOMMENDATIONS 8.0 INTRODUCTION Our exploration indicates that from a geotechnical standpoint, the parcel is suitable for the proposed development provided the risks discussed are accepted and the recommendations contained herein are properly followed. We anticipate that construction of the pools will require excavation to depths of about 8 to 10 feet. The bearing stratum of medium dense to dense alluvium occurs at depths ranging from 8 to 10 feet within the proposed changing room building area, and depths ranging from 1 to 10 feet within the currently proposed pool areas. Therefore, it may be beneficial to consider relocating the proposed structures such that the pools are located within the areas of deeper bearing soils, and the buildings are located near the southeast site corner where shallow bearing soils occur. Limited removal and replacement of the loose surficial deposits is recommended for conventional foundation support. Alternately, short aggregate pier foundations could be used for support of the building using a higher allowable bearing pressure. 9.0 SITE PREPARATION Site preparation of planned building, pool, and other improvement areas should include removal of all trees, and any other deleterious material. Following demolition of the existing covered picnic area, any remaining foundation elements should be removed. Any buried utilities should be removed or relocated if they are under building or pool construction areas. The resulting depressions should be backfilled with structural fill as discussed under the Structural Fill section of this report. Additionally, the upper sod and organic topsoil should be removed and the remaining roots grubbed. Areas where loose surficial soils exist due to grubbing operations should be considered as fill to the depth of disturbance and treated as subsequently recommended for structural fill placement. In the explorations completed for this study, the bearing stratum of medium dense to dense alluvium occurs at depths ranging from 8 to 10 feet within the proposed building area, and depths ranging from 1 to 10 feet within the currently proposed pool areas. Since the density of the soil at the site is highly variable, random soft pockets may exist at the indicated bearing depth. Therefore, the depth and extent of stripping can best be determined in the field by the geotechnical engineer. Where possible, building, sidewalk areas, and pool excavation subgrades should be proof- rolled with a loaded, tandem-axle dump truck to identify any soft spots; soft areas should be overexcavated and backfilled with structural fill. If proof-rolling is not possible within the construction space or construction is to proceed during wet weather, we recommend systematic probing in place of proof-rolling to identify soft areas of the exposed subgrade. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/[b-KE02672A3-Projects12002672IKEIWP-W2K Page 7 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations In our opinion, stable construction slopes should be the responsibility of the contractor and should be determined during construction. For estimating purposes, however, we anticipate that temporary, unsupported cut slopes in the loose to medium dense sand and gravel alluvium can be made at a maximum slope of 2H:1V(Horizontal:Vertical). As is typical with earthwork operations, some sloughing and raveling may occur and cut slopes may have to be adjusted in the field. In addition, WISHA/OSHA regulations should be followed at all times. 10.0 STRUCTURAL FILL All references to structural fill in this report refer to subgrade preparation, fill type, and placement and compaction of materials as discussed in this section. If a percentage of compaction is specified under another section of this report, the value given in that section should be used. Construction plans are preliminary at this stage and do not include site grading information. However, placement of structural fill may be necessary in order to achieve the desired site grades. After stripping, planning excavation, and any required overexcavation has been performed to the satisfaction of the geotechnical engineer, the upper 12 inches of exposed ground in building areas or areas to receive fill should be recompacted to 90 percent of the modified Proctor maximum density using ASTM:D-1557 as the standard. Some of the near- surface soils contain moderate quantities of silt and are considered somewhat moisture- sensitive. Therefore, if the subgrade contains too much moisture, adequate recompaction may be difficult or impossible to obtain, and should probably not be attempted before allowing the subgrade to dry/drain adequately. After recompaction of the exposed ground is tested and approved, structural fill may be placed to attain desired grades. Structural fill is defined as non-organic soil, acceptable to the geotechnical engineer, placed in maximum 8-inch loose lifts with each lift being compacted to 95 percent of the modified Proctor maximum density using ASTM:D-1557 as the standard. The majority of on-site soils are suitable for use as structural fill. In the case of utility trench filling, the backfill should be placed and compacted in accordance with current local or county codes and standards. The top of the compacted fill should extend horizontally outward a minimum distance of 3 feet beyond the location of the perimeter footings before sloping down at an angle of 2H:1V. The contractor should note that any proposed fill soils must be evaluated by AESI prior to their use in fills. This would require that we have a sample of the material 72 hours in advance to perform a Proctor test and determine its field compaction standard. Soils in which the amount of fine-grained material (smaller than No. 200 sieve) is greater than approximately 5 percent (measured on the minus No. 4 sieve size) should be considered moisture-sensitive. Use of moisture-sensitive soil in structural fills should be limited to favorable dry weather conditions. The upper 3 to 4 feet of soil over portions of the site contain more than 12 percent silt. As December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projecrs12002672IKEIWP-W2K Page 8 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations such, some of the site soils are considered moisture-sensitive. In addition, construction equipment traversing the site when the soils are wet can cause considerable disturbance. If fill is placed during wet weather or if proper compaction cannot be obtained, a select import material consisting of a clean, free-draining gravel and/or sand should be used. Free-draining fill consists of non-organic soil with the amount of fine-grained material limited to 5 percent by weight when measured on the minus No. 4 sieve fraction and at least 25 percent retained on the No. 4 sieve. A representative from our firm should inspect the stripped subgrade and be present during placement of structural fill to observe the work and perform a representative number of in- place density tests. In this way, the adequacy of the earthwork may be evaluated as filling progresses, and any problem areas may be corrected at that time. It is important to understand that taking random compaction tests on a part-time basis will not assure uniformity or acceptable performance of a fill. As such, we are available to aid the owner in developing a suitable monitoring and testing frequency. 11.0 FOUNDATIONS Spread Footings Spread footings may be utilized for building support when founded either directly on the medium dense to dense alluvial sand and gravel deposits, or a zone of structural fill that extends down to a depth of 4 feet below the base of foundations or to the medium dense sand and gravel deposits, whichever is less. Structural fill should conform to that described under the Site Preparation and Structural Fill sections of this report. Structural fill placed below footings must extend a minimum of 5 feet beyond the edges of the footings. We recommend that an allowable bearing pressure of 2,000 pounds per square foot (psf) be utilized for design purposes, including both dead and live loads for footings founded either directly upon the medium dense to dense alluvial sand and gravel deposits or structural fill as described above. An increase of one-third may be used for short-term wind or seismic loading. For higher allowable soil bearing pressures, the foundation should be supported by short aggregate piers (Geopiers') as presented subsequently. Perimeter footings for the proposed buildings should be buried a minimum of 18 inches into the surrounding soil for frost protection. No minimum burial depth is required for interior footings; however, all footings must penetrate to the prescribed bearing stratum and no footings should be founded in or above loose or organic existing soils. To limit settlements, all footings should have a minimum width of 14 inches for one-story structures or 16 inches for two-story structures. It should be noted that the area bounded by lines extending downward at 1H:1V from any footing must not intersect another footing or intersect a filled area which has not been compacted to at least 95 percent of ASTM:D-1557. In addition, a 1.5H:1V line extending December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/(b-KE02672A3-Projecu12 002 6 72 1KE1WP-W2K Page 9 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations down from any footing must not daylight because sloughing or raveling may eventually undermine the footing. Thus, footings should not be placed near the edge of steps or cuts in the bearing soils. Anticipated settlement of footings founded as described above should be on the order of 34 inch. However, disturbed soil not removed from footing excavations prior to footing placement could result in increased settlements. All footing areas should be inspected by AESI prior to placing concrete to verify that the design bearing capacity of the soils has been attained and that construction conforms to the recommendations contained in this report. Such inspections may be required by the governing municipality. Perimeter footing drains should be provided as discussed under the section on Drainage Considerations. Aggregate Pier Foundations An alternative to supporting the building on a limited thickness of structural fill with a reduced bearing pressure would be to prepare the building pad for construction by installation of short aggregate piers (GeopiersTM). Aggregate piers are constructed by creating a drilled cavity in the matrix soil, and filling the cavity with aggregate that is densely compacted in thin lifts. The compaction typically induces densification in the surrounding matrix soil, and aggregate volumes in excess of the initial cavity volume are expected. Aggregate piers are installed along continuous foundation bearing walls and at spread foundation locations, and may be installed beneath slab-on-grade floor areas, if needed. Following installation of aggregate piers, the site is finish-graded and conventional shallow foundations are constructed above the aggregate piers. If aggregate piers are selected, the pier subcontractor in conjunction with the project structural engineer should provide the final design of the foundation system including the number and locations of piers, depths, diameters, and load bearing capacities. After the piers are designed and constructed, the resulting foundations should yield a bearing capacity of 3,500 to 4,000 pounds per cubic foot (pcf). Pier Inspection The actual total length of each pier will be adjusted in the field based on required capacity and conditions encountered during drilling. Since completion of the pier takes place below ground, the judgment and experience of the geotechnical engineer or his field representative must be used as a basis for determining the required penetration and acceptability of each pier. Consequently, use of the presented pier capacities in the design requires that all piers be inspected by a qualified geotechnical engineer or engineering geologist from our firm who can interpret and collect the installation data and examine the contractors operations. AESI, acting as the owner's field representative, would determine the required lengths of the piers and keep records of pertinent installation data. A final summary report would then be distributed, following completion of pier installation. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/Ib-KE02672A3-Projects120026721KEI WP-W2K Page 10 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations 12.0 FLOOR SUPPORT Slab-on-grade floors can be constructed directly on medium dense to dense alluvium, Geopiers', or a maximum of 2 feet of structural fill compacted to 95 percent of ASTM:D- 1557. Areas of the slab subgrade that are disturbed (loosened) during construction should be recompacted to an unyielding condition prior to placing the pea gravel, as described below. The floor should be cast atop a minimum of 4 inches of washed, uniformly graded granulithic material or pea gravel to act as a capillary break. Areas of slab subgrade that are disturbed (loosened) during construction should be compacted to a non-yielding condition prior to placement of capillary break material. The slab should also be protected from dampness by an impervious moisture barrier or otherwise sealed. The impervious barrier should be placed between the capillary break material and an optional 2- to 3-inch-thick layer of sand. The sand helps to protect the vapor barrier from damage and allows drainage of the slab during curing provided the slab is poured when the sand is dry. Therefore, the sand layer must not be exposed to rain or snow prior to pouring the slab. 13.0 SWIMMING POOL RECOMMENDATIONS We understand a 25-yard, 6-lane lap pool and a wave pool are planned for construction. Since significant excavation for these pools will be required, we recommend the pools be founded on the medium dense to dense gravelly alluvium. We anticipate that construction of the proposed pools will require sloping of the sidewalls of the excavations at slopes of 2H:1V because the cleaner sand within the upper soil horizon will likely not support steeper cut slopes. Therefore, some type of retaining wall or cast-in-place system will be necessary to construct vertical pool side walls. The following section presents appropriate retaining wall design parameters. If some other type of retaining wall or other than a cast-in-place (backfilled) wall is used, we should be provided with pool design drawings to determine if the lateral earth pressures below are appropriate for the proposed design. Ground water was not encountered in our soil borings during our subsurface exploration. However, ground water may rise to elevations high enough to impose hydrostatic pressures on the base and sides of the proposed pools following extended periods of intense precipitation. We installed a piezometer in EB-5 to monitor ground water elevations throughout the winter and spring. Given that the site resides within close proximity to the Cedar River, the pools should be designed with a drainage system to allow for relief of hydrostatic pressure around and beneath the pool. Alternatively, the pool should be designed to accommodate hydrostatic uplift pressures. With ongoing ground water monitoring, it will be possible to estimate a seasonal high ground water level for incorporation into the design. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projects12002672IKEIWP-W2K Page 11 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Reconunendations 14.0 LATERAL WALL PRESSURES Finished floor elevations were not provided. However, we anticipate that retaining walls may be necessary for the proposed construction. All backfill behind walls or around foundation units should be placed as per our recommendations for structural fill and as described in this section of the report. Horizontally backfilled walls, which are free to yield laterally at least 0.1 percent of their height, may be designed using an equivalent fluid equal to 35 pcf. Fully restrained, horizontally backfilled rigid walls, which cannot yield, should be designed for an equivalent fluid of 50 pcf. If parking areas are adjacent to walls, a surcharge equivalent to 2 feet of soil should be added to the wall height in determining lateral design forces. The lateral pressures presented above are based on the conditions of a uniform backfill consisting of on-site sand and gravel soil, compacted to 90 percent of ASTM:D-1557. A higher degree of compaction is not recommended, as this will increase the pressure acting on the wall. A lower compaction may result in settlement of structures, utilities, or concrete pavement placed above the walls. Thus, the compaction level is critical and must be tested by our firm during placement. Surcharges from adjacent footings, heavy construction equipment, or sloping backfill must be added to the above values. Perimeter footing drains should be provided for all retaining walls as discussed under the section on Drainage Considerations. It is imperative that proper drainage be provided so that hydrostatic pressures do not develop against the wall. This would involve installation of a minimum 1-foot-wide washed gravel blanket drain, which is continuous with the perimeter footing drain and extends to within 1 foot of the ground surface. 14.1 Passive Resistance and Friction Factors Lateral loads can be resisted by friction between the foundation and the natural alluvial soils or supporting structural fill, or by passive earth pressure acting on the buried portions of the foundations. The foundations must be backfilled with structural fill and compacted to at least 95 percent of the maximum dry density to achieve the passive resistance provided below. We recommend the following design parameters: • Passive equivalent fluid = 250 pcf • Coefficient of friction = .35 The above values are allowable and include a safety factor of at least 1.5. 15.0 DRAINAGE CONSIDERATIONS The majority of on-site soils will likely provide adequate drainage during post-construction heavy precipitation events. However, some method should be in place to contain any storm December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/tb-KE02672A3-Projects12002672IKEIWP-W2K Page 12 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations water runoff and discharge it to a suitable collection system during the earthwork portion of construction in the event that runoff does occur. Therefore, prior to site work and during construction, the contractor should be prepared to provide temporary storm water storage or discharge mechanisms as necessary. All retaining and footing walls should be provided with a drain at the footing elevation. Drains should consist of rigid, perforated, PVC pipe surrounded by washed pea gravel. The level of the perforations in the pipe should be at the bottom of the footing at all locations and the drains should be constructed with sufficient gradient to allow gravity discharge away from the building. In addition, all retaining walls should be lined with a minimum 12-inch-thick washed gravel blanket provided over the full height of the wall, and which ties into the footing drain. Roof and surface runoff should not discharge into the footing drain system but should be handled by a separate, rigid, tightline drain. In planning, exterior grades adjacent to walls should be sloped downward away from the structure to achieve surface drainage. 16.0 PAVEMENT RECOMMENDATIONS Based on our current understanding of the project, construction of new asphalt pavement is not planned. However, site surfacing will likely consist of concrete pavement. Site preparation for these areas should consist of overexcavating to remove the existing vegetation, topsoil, and any loose/soft upper soils to expose the underlying stable soils. Since the density of the upper soils is variable, random loose/soft areas may exist and the depth and extent of stripping can best be determined in the field by the geotechnical engineer. To limit differential settlement and cracking of the concrete pavement, we recommend overexcavating areas to receive concrete by 18 inches and replacing this material with compacted structural fill. The excavated soils can be used as fill provided the moisture content at the time of compaction allows for the minimum specified compaction. In addition, the subgrade should be slightly inverted to drain toward the catch basins or surface drains. After the area to be paved is overexcavated, the exposed ground should be recompacted to 95 percent of ASTM:D-1557. Structural fill may then be placed to achieve desired subbase grades. Upon completion of the recompaction and structural fill placement, the recommended minimum pavement section is 6 inches of reinforced concrete pavement underlain by 4 inches of 11/4-inch minus crushed rock base course with less than 3 percent material retained on the No. 200 sieve. The crushed rock course must be compacted to 95 percent of the maximum density. 17.0 PROJECT DESIGN AND CONSTRUCTION MONITORING At the time of this report, site grading, structural plans, and construction methods have not been developed.

We recommend that AESI perform a geotechnical review of the plans prior to final design completion. In this way, our earthwork and foundation recommendations may be properly interpreted and implemented in the design. We are also available to provide geotechnical engineering and monitoring services during construction. The integrity of the foundation depends on proper site preparation and construction procedures. In addition, engineering decisions may have to be made in the field in the event that variations in subsurface conditions become apparent. Construction monitoring services are not part of this current scope of work. If these services are desired, please let us know and we will prepare a cost proposal.

OLD BUSINESS Council President Keolker-Wheeler presented a report regarding the tracking of Committee of the Whole restrictive covenants required through the permit process. Until a few years Development Services: ago,covenants restricting the development of property were difficult to track. Tracking Restrictive Staff generally did not know if any restrictive covenants affected a property Covenants unless a title report was provided. Title reports are expensive for applicants and are only required for certain types of land use applications. At the end of 1999, staff completed a project cataloging and mapping all of the restrictive covenants required by the City. Staff can now research the covenants by consulting a map to identify affected properties. A corresponding database provides the recording number of the restrictive covenant, a legal description of the subject property, and a summary of the requirement of the covenants. In addition,the Permits Plus permit tracking system is utilized to document conditions of permit approval, including covenants. These conditions can be researched by project name, address or parcel identification number. Another tool developed by staff to track project conditions is a matrix summarizing the required conditions. Copies of this matrix are distributed to the contractors and inspectors at pre-construction meetings. The Committee recommended no further action be taken at this time.

February 25, 2003 OFFICE OF THE HEARING EXAMINER CITY OF RENTON REPORT AND RECOMMENDATION APPLICANT: Dennis Culp City of Renton 1055 South Grady Way Renton, WA 98055 Renton Aquatic Center File No.: LUA-02-147,SA-H, ECF LOCATION: 1715 Maple Valley Highway SUMMARY OF REQUEST: The construction of an aquatic center featuring a leisure pool, lap pool, changing rooms and concession areas. SUMMARY OF ACTION: Development Services Recommendation: Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on February 11, 2003. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area;the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the February 18,2003 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,February 18, 2003,at 9:04 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Neighborhood Detail Map application, proof of posting, proof of publication and other documentation pertinent to this request. Exhibit No.3: Overall Site Plan Exhibit No. 4: Aquatic Center Site Plan Exhibit No. 5: Building Elevations Exhibit No. 6: Building Floor Plan Exhibit No.7: Utilities &Drainage Control Plan Exhibit No. 8: Landscape Plan Exhibit No. 9: Zoning Map The hearing opened with a presentation of the staff report by Jason Jordan, Associate Planner, Development Services, City of Renton, 1055 S Grady Way, Renton, Washington 98055. Mr. Jordan explained that this site r 1 Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 2 plan review would be a recommendation to Council rather then a Hearing Examiner decision due to it being located in the Center Office Residential(COR)zone. The new City operated Aquatic Center would be located within the existing Cedar River Park site. The proposed Aquatic Center is to be constructed in the northeast corner of the site closest to Maple Valley Highway. The Cedar River is located south and east of the subject site. The Community Center Building and Carco Theatre are also located on this site. There is a large parking lot in the central portion of the property. The parks maintenance buildings are located east and south of the proposed aquatic center site. Interstate 405 and Houser Way are immediately west of the site. The Maple Valley Highway is located north and east of the site. The Stoneway concrete plant is east of the site. The Aquatic Center would include a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Activities with this proposal would include recreational uses,swim lessons,therapeutic uses and occasional swim meets. Construction is planned to begin in April of this year and be substantially completed by December 2003. The City expects to operate the pool from approximately Memorial Day to Labor Day weather permitting. Typical hours of operation will be from dawn to dusk. Access to the site is proposed from two locations. The primary access is proposed from Maple Valley Highway where there is a full-signalized intersection. The secondary access,which is limited to a right in,right out,is from Houser Way North. The Environmental Review Committee(ERC)issued a Determination of Non-Significance-Mitigated(DNS-M) with six mitigation measures for the project. There were no appeals filed. Five of the mitigation measures were standard erosion control mitigation measures. The last mitigation measure was for a Fire Impact Fee. Mr.Jordan reviewed several policies from the Comprehensive Plan and how they are applicable to the project. Staff believes that the Aquatic Center is a nice addition to the current recreational uses within the site. The site is already recreational and this would only be augmenting that use in a high quality manner. The applicant is not proposing any additional parking and they have done a fairly thorough investigation of getting pedestrian and vehicular access off the roads to the parking areas and to the aquatic center. In regard to conformance with land use regulations,the COR zone allows Aquatic Center uses as primary permitted uses in this zone. The Development Standards with regard to lot coverage allow up to 65 percent coverage in the COR zone. This particular project only has lot coverage of 6.5 percent with the additional 6,500 square feet of building area. In regard to setbacks,the proposed aquatic center is located 100 feet from the Maple Valley Highway and 500 feet from the Cedar River. It is also located 480 feet from Houser Way and 160 feet from the Stoneway Concrete plant. The Aquatic Center has substantial setbacks that would mitigate any potential concerns from neighboring properties. The required landscaping is already in place as part of the development. The proposed Aquatic Center at 19 feet in height is well below the 125 feet maximum allowed in the COR zone. There are an existing 400 parking stalls at the site. Development code requires one stall per 100 square feet. The zoning code did not have a ratio for parking for swimming pools so staff used the community center type parking requirements for the aquatic center use. This would have required an additional 266 parking stalls for Renton Aquatic Center • File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 3 the Aquatic Center use;however,the applicant put together a pretty solid argument indicating that the one per 100 square feet is too high for the Aquatic Center and the demand would be far less. Secondly,the Community Center,Carco Theater and the Renton Aquatic Center will have different peak hours of operation and the 400 stalls currently available would be adequate. Staff reviewed this information and administration issued a parking modification for the project. The proposal is located within an existing park site and has already been utilized as recreation. Staff feels that because the existing uses are recreational there should be no impacts to surrounding properties. Construction activities would result in short term noise,dust and traffic impacts;however,these will be limited to the construction phase and would be subject to a construction mitigation plan. A geotechnical report was submitted for the project. The report indicated that the site is appropriate for this type of use. The ERC did mitigate erosion for the site with the primary emphasis on no impacts to the Cedar River. The ERC mitigation measure should minimize any impacts of the site plan to the site. In regard to questioning from the Examiner,Mr. Jordan stated that after construction the site would be fenced with chain link fence and separated from the rest of the park area for safety reasons. The site is located within the Aquifer Protection Area(APA)zone. There will be some typical pool treatment chemicals on-site; however,they are below the maximum allowed for the APA zone. Staff expects that the Aquatic Center would increase the property values in the vicinity of the site. A traffic study was not required for this project. The project is not providing any additional parking but what the applicant has done is propose some extensive striping. There is already a paved walkway from the parking area next to the Maple Valley Highway that leads right past the site and continues on to the other buildings. With respect to parking in the main parking lot the applicant has put together a fairly good striping plan to allow for safe vehicle and pedestrian movement. The Aquatic Center is largely comprised of an open outdoor recreation area. There are some buildings but they are limited to 19 feet in height and located in the south corner and staff does not expect these buildings to impede any light or air circulation to the site. The buildings are not going to impact any of the other recreational opportunities in staff's opinion. The proposed development would not generate any harmful or unhealthy conditions. There would be noise impacts related to increased traffic and activity normally associated with recreational use. The Fire and Police Departments have indicated that they have sufficient resources to adequately accommodate the subject proposal provided the applicant pay the required Fire Mitigation Fee. Police did extensively review this project and do have concerns with safety and did have some suggestions for the construction phase of the project. Staff does not expect any neighborhood deterioration or blight and in fact expects the opposite. One of the criteria for the COR zone is that planning incorporates public and private open space to provide adequate areas for passive and active recreation. The site is entirely dedicated to recreation and has both active and passive recreation opportunities. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 4 The plan does provide view corridors to the shoreline areas. Staff does not expect any view corridors to be blocked. The project is setback over 500 feet from the Cedar River and the buildings are limited to 19 feet in height. There is still access to the Cedar River and the aquatic center will not be blocking access in any way. Mr. Jordan stated that there is additional review criteria for the COR zone and asked to clarify that typically for the COR zone there is a requirement that the site plan reviews go through a Level II Site Plan Review. Because this proposal did not go through a Level II Site Plan Review,the additional criteria must be reviewed. Staff does not believe that the two buildings would be an over concentration. The majority of the site is still predominantly open space. The applicant attempted to locate the pool in a more flat area so that less grading would have to occur and to be the least impact to the Cedar River. The lighting plan clearly shows that the lighting would be adequate for not only safety but also security and the lighting does not spill onto neighboring properties and certainly does not spill onto the Cedar River site. Staff believes that the applicant has put together a good site plan trying to tie in the natural areas and the open space areas. The structures proposed should not be an overburden to the existing site or be out of scale with the existing buildings on the site. The applicant will not be adding any additional impervious surface due to parking. The swimming pools will be tied into the sewer system. The swim decks are below the threshold for any type of water quality treatment. This is a very low impact development on the existing Cedar River site. Mr. Jordan added that there would be quite a few landscaped areas throughout the site. Staff recommends approval of the Renton Aquatic Center with no conditions. Boris Srdar,Northwest Architectural Company,2201 6'h Avenue,#1405, Seattle,WA 98121 stated that this is the first facility of this type in the area. This is the third project of this kind that he has worked on. Experience tells them that about 50 percent of people who use the pools do not require parking. These types of facilities are very popular with children from the age of seven into their early teens. Most of the vehicles that do park are not single occupancy vehicles they are families with children. These facts combined with the occupancy rate of the facility means that less then half of the parking would go to the pool. In response to questioning from the Examiner regarding fencing,Mr.Srdar stated that given the priorities of the pool and the amenities to meet the base cost they have decided to use the chain link fencing rather then a wrought iron or something else. Mr.Jordan stated that he has checked with the applicant and the difficulty is the budget. They all agree that the wrought iron fence is much more aesthetically pleasing. One issue is that on the northwestern boundary of the pool the fence has to be a certain height because of the location of the ball fields. It may be possible to use wrought iron in the front of the aquatic center and have the rest be painted cyclone. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at 9:57 a.m. FINDINGS,CONCLUSIONS&RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 5 Findings: 1. The applicant,Dennis Culp,representing the City of Renton, filed a request for approval of a Site Plan for a new Aquatic Center. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non- Significance- Mitigated(DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. There was no opposition from the public regarding the subject proposal. 6. The subject site is located 1715 Maple Valley Highway. The subject site is located on the south side of the highway immediately east of I-405 and just east of downtown Renton. The subject site is located in the northeast corner of the Cedar River Park complex that contains the Renton Community Center building and Carco Theater. The Cedar River is located south of the subject site. . i 7. The subject site is approximately 240 feet wide(Maple ValleyFrontage)by320 feet deep. The subject PP Y ( P g ) J site is approximately 1.75 acres of the approximately 20-acre park site. 8. The subject site was annexed to the City with the adoption of Ordinance 1212 enacted in April 1945. 9. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of Center Office and Residential uses, but does not mandate such development without consideration of other policies of the Plan. 10. The subject site is zoned COR(Center Office Residential)a zoning designation applied to the subject site in June 1993. The COR zone permits parks and aquatic facilities. 11. The site east of the subject site,the concrete plant,is also zoned COR. The concrete plant is in the process of being decommissioned. There is a CA(Commercial Arterial)zone north of the site, across Maple Valley Highway. The Cedar River corridor and slopes on its south side are zoned RC(Resource Conservation). 12. The applicant proposes developing an Aquatic Center that contains four components. It will contain two outdoor pools including a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Complementing the two pools will be two buildings. These buildings will be approximately 6,500 square foot. There will be a changing rooms building that is approximately 32 feet wide by 160 feet long located in the southern portion of the site. The concessions area will be west of the changing area and will be approximately 48 feet square. Additional restrooms are located in the northeast corner of the site. 13. The leisure pool will be an elaborate facility with river area,wave area as well as a plunge area and other features. 14. The buildings will be one-story or approximately 19 feet tall. The COR zone permits buildings of 10 Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 6 stories or 125 feet tall. 15. There will be internal landscaping and the applicant will be taking advantage of existing landscaping that borders the existing park along its edges and frontage. 16. Staff analyzed the parking requirements for the use as well as the other uses that share the entire site. Currently there are 400 parking stalls located on the site serving the community center and the theater. The Community Center requires one stall per 100 square feet or 354 stalls and those are all provided. Carco Theater requires one stall per four fixed seats or 75 stalls and only 46 are provided. That's a deficit of 29 stalls. Code does not specifically address either pools or the more elaborate Aquatic Center. Staff compared the use to indoor or outdoor arenas or stadiums,which require one stall per 100 square feet like the Community Center itself. Staff calculated the Aquatic Center would require 266 stalls. The City's consultant reviewed the site,parking usage and similar uses and determined that the existing 400 stalls could reasonably serve the pool patrons. In addition,they anticipate that the theater and pool would have different demand hours. They expect a number of the patrons to be children who will be dropped off by parents or arrive by bicycle or in carpools with friends. The applicant noted that there is room on the grounds to provide additional parking if it is determined that their is insufficient parking. They would prefer saving the lawn areas if the parking were unnecessary. The applicant was granted an Administrative Parking Modification from the Code based on these various analyses. 17. The subject site will have two points of access. The main entry will be the signal-controlled intersection along the Maple Valley Highway. A second access is Houser Way via a tunnel under I-405. There will be a pullout near the entrance to the pool complex to allow drop-offs. Traffic will circulate around the east side of the new complex. 18. The new complex will be approximately 500 feet from the Cedar River. It will be setback approximately 480 feet from Houser Way and slightly less from I-405. The complex will be setback approximately 100 feet from the Maple Valley Highway and 160 feet from its eastern property line,the one shared with the cement plant. 19. The proposal requires 10 feet of landscaping along the Maple Valley Highway setback. The current landscaping will provide that setback. 20. The development of the swimming complex will result in the loss of lawn area replaced by the complex as well as a large Big Leaf Maple and nine Pin Oak trees. 21. The applicant proposed using chain link fencing to provide security around the subject site. The pool needs to be protected from illegal entry,particularly after hours. The applicant also noted that the pool and its patrons need to be protected from balls that might go astray from the nearby playfields. This office suggested that since the applicant considers this a gateway site for the City that more appropriate, aesthetically pleasing fencing such as wrought iron be used. The applicant indicated budget constraints might limit the ability to upgrade but might be able to use it along the Maple Valley frontage. 22. The aquatic center would replace the previous pool(Henry Moses Pool)at Liberty Park,which was demolished in 1999. 23. Construction of the complex is planned to begin in April 2003 and be substantially completed by December 2003. 24. The subject site is located in the Aquifer Protection Zone. No impacts on water quality are anticipated. The Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 7 storage of pool cleaning chemicals will follow standard practices. Conclusions: l. The COR Zoning requires that an approval of a Site Plan be done by the City Council in this case. The COR zoning provides an extensive list of criteria to judge whether a proposal is appropriate in the zone as well as criteria for a Level I Site Plan as well as the normal criteria for Site Plan review. Some of the criteria overlap. 2. The site plan ordinance provides a number of specific criteria for reviewing a site plan. Those criteria are generally represented in part by the following enumeration: a. Conformance with the Comprehensive Plan; b. Conformance with the Building and Zoning Codes; c. Mitigation of impacts on surrounding properties and uses; d. Mitigation of the impacts of the proposal on the subject site itself; e. Conservation of property values; f. Provision for safe and efficient vehicle and pedestrian circulation; g. Provision of adequate light and air; h. Adequacy of public services to accommodate the proposed use; The proposed use satisfies these and other particulars of the ordinance. 3. The COR designation in the Comprehensive Plan suggests a coherent,high quality development that takes advantage of natural amenities. The proposed complex has been designed to provide a center for recreational opportunities in a unified campus. The pool complex has been designed to fit in with the general size and scale of the existing Recreation and Carco buildings. The low-rise nature is intended to keep the site open appearing and minimize impacts on the nearby Cedar River. 4. The one-story buildings,the setbacks and landscaping meet the limits provided by the Zoning Code. Detailed analysis of building code and fire code compliance will be determined when the building permit is submitted for review. The proposal has been granted a modification from parking standards based on an analysis of current parking demands as well as projected demands of the specific use. 5. The low-rise complex should have few if any impacts on surrounding properties. The complex is setback 160 feet from adjoining private property to the east. It will have a 100-foot setback from Maple Valley and is separated from the Cedar River by the other uses already established on the subject site. The use of chain link fencing for such a prominent site is unfortunate. If the City can fund an upgrade to make this gateway site more aesthetically pleasing it should do so while, clearly,not compromising the safety and security of patrons and the complex itself. 6. The open space at Cedar River Park will be diminished by the complex and some older, larger trees will need to be removed. The tradeoff is providing a quality swimming complex and new landscaping inside Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 8 the complex should soften its appearance especially when coupled with the existing landscaping. The construction will have clear short-term impacts including noise. The completed facility should have few impacts other than possibly noise associated with boisterous patrons. It will also probably generate additional visitation to the park during the summer months when the pool is operating. 7. The development should not adversely affect property values. It is planned as a high quality addition to the recreational amenities offered by the City. 8. The proposal will use the existing parking lot,which has proved adequate in both terms of efficiency and circulation. The pool complex will have a drop-off lane near its entrance to accommodate parents dropping off children to use the complex. The applicant will be restriping some of the parking and walking areas to accommodate pedestrians. 9. There will be adequate light and air in and around the one-story, open pool complex. 10. There is a full complement of public services to accommodate the facility. 11. The subject site is not located in the Urban Center Design Overlay area and is not subject to those special regulations. 12. Section 4-9-200E1k provides "Additional Special review Criteria for COR Zone Only:" and those in part include: 1. The plan is consistent with the Planned Action Ordinance, if applicable. 2. The plan creates a compact, urban development that includes a compatible mix of uses where appropriate. 3. The plan provides an overall urban design concept that is internally consistent and harmonious with development on adjacent sites. 4. The plan incorporates public and private open spaces to provide adequate area for passive and active recreation by the occupants/users of the site and/or protecting existing natural systems. 5. The plan provides view corridors to the shoreline areas where applicable. 6. Public access is provided to water and/or shoreline areas. 7. The plan provides distinctive focal points such as public area plazas, prominent architectural features or other items. 8. The plan assures adequate access to public streets. 9. The plan accommodates and promotes transit, pedestrian and other alternative modes of transportation. 13. The Aquatic Center proposal does not need a "Planned Action Ordinance." 14. The Aquatic Center is part of an urban park system. It contains, as a park should, open space. It is not an inherently compact urban proposal but concentrates many of Renton's community recreation facilities in Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 9 this one location. 15. The entire park concept has been developed to be homogeneous. While new elements such as the pool complex and the Community facility are or have been added,they are designed to blend with the existing park and facilities including the Carco Theater. Development around the site is sparse with I-405 and the Cedar River providing the most defined uses and the cement plant being phased out over the next few years. 16. The park provides its own open space unlike a private development proposal. The immediate pool complex provides the open water pools and two smaller buildings. The new complex should not affect the existing natural systems,which would be the Cedar River and the underlying drinking water aquifer. 17. The proposed aquatic complex should not severely impact any view corridors. Other buildings are already located between the Maple Valley Highway and the Cedar River. In addition,nothing about the new complex would detract from current access to the river and it's viewing and seating areas. 18. The aquatic center probably will become a new focal point for the Cedar River Park in itself. The entire recreational complex,though,serves this function. Hopefully, a more aesthetic fencing arrangement can further enhance the complex's prominent features. 19. The park's location at the intersection of the Maple Valley Highway and I-405 should assure access to public streets. The wall of I-405 and the Cedar River limit access but the City has managed two points of access,which seems appropriate. Two points of access also limits the number of driveways within the park system making it more internally user friendly. 20. The site is adjacent to the Cedar River trail system as well as the state and interstate highway system. Access should be reasonable. 21. Finally,another set of criteria,those for a Level I Site Plan(Section 4-9-200F),must be reviewed. Some of the criteria overlap those reviewed above. The criteria contain the following provisions: 1. Review of Impacts to Surrounding Properties and Uses. 2. Review of Impacts of a Proposed Site Plan to the Site. 3. Review of Circulation and Access. 4. Review of Signage. 5. Special Review Criteria for Hazardous Waste Treatment and Storage Facilities. 6. Review of Street Frontage Landscape. 22. Again,the development of the new aquatic complex should not impair the use of any surrounding properties or uses. It should not bring unnecessary traffic to the area and such traffic would be limited, after construction,to passenger vehicles in the main. The hours will generally not conflict with peak hour traffic demands. The buildings and pools have been located so as not to impact adjacent park or non-park uses. The design, as a whole, should enhance the general look of the campus and is designed to appear to be part of the existing campus. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 10 23. As already noted,the development will decrease the open space at this park. That seems a justifiable balancing of the interests inherent in creating a summer swimming venue at an existing,centrally located park facility. The applicant has minimized the intrusions but some loss will occur. 24. The two points of access are pretty well defined by the location and existing development pattern of a parcel located in the southeast quadrant of the I-405/Maple Valley Highway intersection. The main, signalized intersection will provide reasonable access to all points of the City. The secondary Houser Way tunnel is a limited but available route that has served reasonably well. The combination has limited the number of entrances and maintained parkland. The applicant has provided for internal vehicular and pedestrian circulation. A drop-off will provide a safety zone for arriving vehicles dropping off pedestrians. 25. The Park already has signs. As staff noted,any new signs would meet the City's own requirements. 26. While some chemicals for treating the pool might be considered hazardous,their number and quantity will be limited. Staff reported that they would be below triggering thresholds of the Aquifer Protection Ordinance. They would also be stored in legal forms and containers. 27. The applicant will not be altering any of the landscaping found along the streets adjacent to the subject site. Some ten larger,mature trees will be removed to accommodate the proposal but these are not frontage trees. Internal landscaping as well as the leisure pool will serve as both landscape and water elements for the new aquatic center. 28. In conclusion,the proposed Aquatic Center appears to be a well-designed complex in its own right but also will be well integrated into the existing facilities located at Cedar River Park. It will replace a solely missed element;the now closed Henry Moses Pool, in summer fun in the City. Recommendation: The City Council should approve the Site Plan for the City of Renton Aquatic Center subject to the following conditions: 1. The applicant shall comply with the conditions imposed by the ERC. 2. If the City can fund an upgrade to make the fencing of this gateway site more aesthetically pleasing it should do so while,clearly,not compromising the safety and security of patrons and the complex itself.

SUMMARY OF ACTION: Development Services Recommendation: Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on February 11,2003. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area;the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the February 18,2003 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,February 18,2003,at 9:04 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Neighborhood Detail Map application,proof of posting,proof of publication and other documentation pertinent to this request. Exhibit No.3: Overall Site Plan Exhibit No.4: Aquatic Center Site Plan Exhibit No.5: Building Elevations Exhibit No.6: Building Floor Plan Exhibit No.7: Utilities&Drainage Control Plan Exhibit No.8: Landscape Plan Exhibit No.9: Zoning Map The hearing opened with a presentation of the staff report by Jason Jordan,Associate Planner,Development Services,City of Renton, 1055 S Grady Way,Renton,Washington 98055. Mr.Jordan explained that this site Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 2 plan review would be a recommendation to Council rather then a Hearing Examiner decision due to it being located in the Center Office Residential(COR)zone. The new City operated Aquatic Center would be located within the existing Cedar River Park site. The proposed Aquatic Center is to be constructed in the northeast corner of the site closest to Maple Valley Highway. The Cedar River is located south and east of the subject site. The Community Center Building and Carco Theatre are also located on this site. There is a large parking lot in the central portion of the property. The parks maintenance buildings are located east and south of the proposed aquatic center site. Interstate 405 and Houser Way are immediately west of the site. The Maple Valley Highway is located north and east of the site. The Stoneway concrete plant is east of the site. The Aquatic Center would include a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Activities with this proposal would include recreational uses, swim lessons,therapeutic uses and occasional swim meets. Construction is planned to begin in April of this year and be substantially completed by December 2003. The City expects to operate the pool from approximately Memorial Day to Labor Day weather permitting. Typical hours of operation will be from dawn to dusk. Access to the site is proposed from two locations. The primary access is proposed from Maple Valley Highway where there is a full-signalized intersection. The secondary access,which is limited to a right in,right out, is from Houser Way North. The Environmental Review Committee(ERC)issued a Determination of Non-Significance-Mitigated(DNS-M) with six mitigation measures for the project. There were no appeals filed. Five of the mitigation measures were standard erosion control mitigation measures. The last mitigation measure was for a Fire Impact Fee. Mr. Jordan reviewed several policies from the Comprehensive Plan and how they are applicable to the project. Staff believes that the Aquatic Center is a nice addition to the current recreational uses within the site. The site is already recreational and this would only be augmenting that use in a high quality manner. The applicant is not proposing any additional parking and they have done a fairly thorough investigation of getting pedestrian and vehicular access off the roads to the parking areas and to the aquatic center. In regard to conformance with land use regulations,the COR zone allows Aquatic Center uses as primary permitted uses in this zone. The Development Standards with regard to lot coverage allow up to 65 percent coverage in the COR zone. This particular project only has lot coverage of 6.5 percent with the additional 6,500 square feet of building area. In regard to setbacks,the proposed aquatic center is located 100 feet from the Maple Valley Highway and 500 feet from the Cedar River. It is also located 480 feet from Houser Way and 160 feet from the Stoneway Concrete plant. The Aquatic Center has substantial setbacks that would mitigate any potential concerns from neighboring properties. The required landscaping is already in place as part of the development. The proposed Aquatic Center at 19 feet in height is well below the 125 feet maximum allowed in the COR zone. There are an existing 400 parking stalls at the site. Development code requires one stall per 100 square feet. The zoning code did not have a ratio for parking for swimming pools so staff used the community center type parking requirements for the aquatic center use. This would have required an additional 266 parking stalls for Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 3 the Aquatic Center use; however,the applicant put together a pretty solid argument indicating that the one per 100 square feet is too high for the Aquatic Center and the demand would be far less. Secondly,the Community Center,Carco Theater and the Renton Aquatic Center will have different peak hours of operation and the 400 stalls currently available would be adequate. Staff reviewed this information and administration issued a parking modification for the project. The proposal is located within an existing park site and has already been utilized as recreation. Staff feels that because the existing uses are recreational there should be no impacts to surrounding properties. Construction activities would result in short term noise, dust and traffic impacts; however,these will be limited to the construction phase and would be subject to a construction mitigation plan. A geotechnical report was submitted for the project. The report indicated that the site is appropriate for this type of use. The ERC did mitigate erosion for the site with the primary emphasis on no impacts to the Cedar River. The ERC mitigation measure should minimize any impacts of the site plan to the site. In regard to questioning from the Examiner,Mr.Jordan stated that after construction the site would be fenced with chain link fence and separated from the rest of the park area for safety reasons. The site is located within the Aquifer Protection Area(APA)zone. There will be some typical pool treatment chemicals on-site; however,they are below the maximum allowed for the APA zone. Staff expects that the Aquatic Center would increase the property values in the vicinity of the site. A traffic study was not required for this project. The project is not providing any additional parking but what the applicant has done is propose some extensive striping. There is already a paved walkway from the parking area next to the Maple Valley Highway that leads right past the site and continues on to the other buildings. With respect to parking in the main parking lot the applicant has put together a fairly good striping plan to allow for safe vehicle and pedestrian movement. The Aquatic Center is largely comprised of an open outdoor recreation area. There are some buildings but they are limited to 19 feet in height and located in the south corner and staff does not expect these buildings to impede any light or air circulation to the site. The buildings are not going to impact any of the other recreational opportunities in staff's opinion. The proposed development would not generate any harmful or unhealthy conditions. There would be noise impacts related to increased traffic and activity normally associated with recreational use. The Fire and Police Departments have indicated that they have sufficient resources to adequately accommodate the subject proposal provided the applicant pay the required Fire Mitigation Fee. Police did extensively review this project and do have concerns with safety and did have some suggestions for the construction phase of the project. Staff does not expect any neighborhood deterioration or blight and in fact expects the opposite. One of the criteria for the COR zone is that planning incorporates public and private open space to provide adequate areas for passive and active recreation. The site is entirely dedicated to recreation and has both active and passive recreation opportunities. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 4 The plan does provide view corridors to the shoreline areas. Staff does not expect any view corridors to be blocked. The project is setback over 500 feet from the Cedar River and the buildings are limited to 19 feet in height. There is still access to the Cedar River and the aquatic center will not be blocking access in any way. Mr. Jordan stated that there is additional review criteria for the COR zone and asked to clarify that typically for the COR zone there is a requirement that the site plan reviews go through a Level II Site Plan Review. Because this proposal did not go through a Level II Site Plan Review,the additional criteria must be reviewed. Staff does not believe that the two buildings would be an over concentration. The majority of the site is still predominantly open space. The applicant attempted to locate the pool in a more flat area so that less grading would have to occur and to be the least impact to the Cedar River. The lighting plan clearly shows that the lighting would be adequate for not only safety but also security and the lighting does not spill onto neighboring properties and certainly does not spill onto the Cedar River site. Staff believes that the applicant has put together a good site plan trying to tie in the natural areas and the open space areas. The structures proposed should not be an overburden to the existing site or be out of scale with the existing buildings on the site. The applicant will not be adding any additional impervious surface due to parking. The swimming pools will be tied into the sewer system. The swim decks are below the threshold for any type of water quality treatment. This is a very low impact development on the existing Cedar River site. Mr. Jordan added that there would be quite a few landscaped areas throughout the site. Staff recommends approval of the Renton Aquatic Center with no conditions. Boris Srdar,Northwest Architectural Company,2201 6th Avenue,#1405, Seattle, WA 98121 stated that this is the first facility of this type in the area. This is the third project of this kind that he has worked on. Experience tells them that about 50 percent of people who use the pools do not require parking. These types of facilities are very popular with children from the age of seven into their early teens. Most of the vehicles that do park are not single occupancy vehicles they are families with children. These facts combined with the occupancy rate of the facility means that less then half of the parking would go to the pool. In response to questioning from the Examiner regarding fencing,Mr. Srdar stated that given the priorities of the pool and the amenities to meet the base cost they have decided to use the chain link fencing rather then a wrought iron or something else. Mr.Jordan stated that he has checked with the applicant and the difficulty is the budget. They all agree that the wrought iron fence is much more aesthetically pleasing. One issue is that on the northwestern boundary of the pool the fence has to be a certain height because of the location of the ball fields. It may be possible to use wrought iron in the front of the aquatic center and have the rest be painted cyclone. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at 9:57 a.m. FINDINGS,CONCLUSIONS&RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 5 Findings: 1. The applicant, Dennis Culp,representing the Cityof Renton,filed a request for approval of a Site Plan for PP R P gq a new Aquatic Center. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non- Significance-Mitigated(DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. There was no opposition from the public regarding the subject proposal. 6. The subject site is located 1715 Maple Valley Highway. The subject site is located on the south side of the highway immediately east of I-405 and just east of downtown Renton. The subject site is located in the northeast corner of the Cedar River Park complex that contains the Renton Community Center building and Carco Theater. The Cedar River is located south of the subject site. 7. The subject site is approximately 240 feet wide(Maple Valley Frontage)by 320 feet deep. The subject site is approximately 1.75 acres of the approximately 20-acre park site. 8. The subject site was annexed to the City with the adoption of Ordinance 1212 enacted in April 1945. 9. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of Center Office and Residential uses,but does not mandate such development without consideration of other policies of the Plan. 10. The subject site is zoned COR(Center Office Residential)a zoning designation applied to the subject site in June 1993. The COR zone permits parks and aquatic facilities. 11. The site east of the subject site,the concrete plant, is also zoned COR. The concrete plant is in the process of being decommissioned. There is a CA(Commercial Arterial)zone north of the site,across Maple Valley Highway. The Cedar River corridor and slopes on its south side are zoned RC(Resource Conservation). 12. The applicant proposes developing an Aquatic Center that contains four components. It will contain two outdoor pools including a 9,520 square foot leisure pool and a 3,837 square foot lap pool. Complementing the two pools will be two buildings. These buildings will be approximately 6,500 square foot. There will be a changing rooms building that is approximately 32 feet wide by 160 feet long located in the southern portion of the site. The concessions area will be west of the changing area and will be approximately 48 feet square. Additional restrooms are located in the northeast corner of the site. 13. The leisure pool will be an elaborate facility with river area,wave area as well as a plunge area and other features. 14. The buildings will be one-story or approximately 19 feet tall. The COR zone permits buildings of 10 Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25, 2003 Page 6 stories or 125 feet tall. 15. There will be internal landscaping and the applicant will be taking advantage of existing landscaping that borders the existing park along its edges and frontage. 16. Staff analyzed the parking requirements for the use as well as the other uses that share the entire site. Currently there are 400 parking stalls located on the site serving the community center and the theater. The Community Center requires one stall per 100 square feet or 354 stalls and those are all provided. Carco Theater requires one stall per four fixed seats or 75 stalls and only 46 are provided. That's a deficit of 29 stalls. Code does not specifically address either pools or the more elaborate Aquatic Center. Staff compared the use to indoor or outdoor arenas or stadiums,which require one stall per 100 square feet like the Community Center itself. Staff calculated the Aquatic Center would require 266 stalls. The City's consultant reviewed the site,parking usage and similar uses and determined that the existing 400 stalls could reasonably serve the pool patrons. In addition,they anticipate that the theater and pool would have different demand hours. They expect a number of the patrons to be children who will be dropped off by parents or arrive by bicycle or in carpools with friends. The applicant noted that there is room on the grounds to provide additional parking if it is determined that their is insufficient parking. They would prefer saving the lawn areas if the parking were unnecessary. The applicant was granted an Administrative Parking Modification from the Code based on these various analyses. 17. The subject site will have two points of access. The main entry will be the signal-controlled intersection along the Maple Valley Highway. A second access is Houser Way via a tunnel under I-405. There will be a pullout near the entrance to the pool complex to allow drop-offs. Traffic will circulate around the east side of the new complex. 18. The new complex will be approximately 500 feet from the Cedar River. It will be setback approximately 480 feet from Houser Way and slightly less from I-405. The complex will be setback approximately 100 feet from the Maple Valley Highway and 160 feet from its eastern property line,the one shared with the cement plant. 19. The proposal requires 10 feet of landscaping along the Maple Valley Highway setback. The current landscaping will provide that setback. 20. The development of the swimming complex will result in the loss of lawn area replaced by the complex as well as a large Big Leaf Maple and nine Pin Oak trees. 21. The applicant proposed using chain link fencing to provide security around the subject site. The pool needs to be protected from illegal entry,particularly after hours. The applicant also noted that the pool and its patrons need to be protected from balls that might go astray from the nearby playfields. This office suggested that since the applicant considers this a gateway site for the City that more appropriate, aesthetically pleasing fencing such as wrought iron be used. The applicant indicated budget constraints might limit the ability to upgrade but might be able to use it along the Maple Valley frontage. 22. The aquatic center would replace the previous pool(Henry Moses Pool)at Liberty Park,which was demolished in 1999. 23. Construction of the complex is planned to begin in April 2003 and be substantially completed by December 2003. 24. The subject site is located in the Aquifer Protection Zone. No impacts on water quality are anticipated.The Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 7 storage of pool cleaning chemicals will follow standard practices. Conclusions: 1. The COR Zoning requires that an approval of a Site Plan be done by the City Council in this case. The COR zoning provides an extensive list of criteria to judge whether a proposal is appropriate in the zone as well as criteria for a Level I Site Plan as well as the normal criteria for Site Plan review. Some of the criteria overlap. 2. The site plan ordinance provides a number of specific criteria for reviewing a site plan. Those criteria are generally represented in part by the following enumeration: a. Conformance with the Comprehensive Plan; b. Conformance with the Building and Zoning Codes; c. Mitigation of impacts on surrounding properties and uses; d. Mitigation of the impacts of the proposal on the subject site itself; e. Conservation of property values; f. Provision for safe and efficient vehicle and pedestrian circulation; g. Provision of adequate light and air; h. Adequacy of public services to accommodate the proposed use; The proposed use satisfies these and other particulars of the ordinance. 3. The COR designation in the Comprehensive Plan suggests a coherent,high quality development that takes advantage of natural amenities. The proposed complex has been designed to provide a center for recreational opportunities in a unified campus. The pool complex has been designed to fit in with the general size and scale of the existing Recreation and Carco buildings. The low-rise nature is intended to keep the site open appearing and minimize impacts on the nearby Cedar River. 4. The one-story buildings,the setbacks and landscaping meet the limits provided by the Zoning Code. Detailed analysis of building code and fire code compliance will be determined when the building permit is submitted for review. The proposal has been granted a modification from parking standards based on an analysis of current parking demands as well as projected demands of the specific use. 5. The low-rise complex should have few if any impacts on surrounding properties. The complex is setback 160 feet from adjoining private property to the east. It will have a 100-foot setback from Maple Valley and is separated from the Cedar River by the other uses already established on the subject site. The use of chain link fencing for such a prominent site is unfortunate. If the City can fund an upgrade to make this gateway site more aesthetically pleasing it should do so while, clearly,not compromising the safety and security of patrons and the complex itself. 6. The open space at Cedar River Park will be diminished by the complex and some older, larger trees will need to be removed. The tradeoff is providing a quality swimming complex and new landscaping inside Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 8 the complex should soften its appearance especially when coupled with the existing landscaping. The construction will have clear short-term impacts including noise. The completed facility should have few impacts other than possibly noise associated with boisterous patrons. It will also probably generate additional visitation to the park during the summer months when the pool is operating. 7. The development should not adversely affect property values. It is planned as a high quality addition to the recreational amenities offered by the City. 8. The proposal will use the existing parking lot,which has proved adequate in both terms of efficiency and circulation. The pool complex will have a drop-off lane near its entrance to accommodate parents dropping off children to use the complex. The applicant will be restriping some of the parking and walking areas to accommodate pedestrians. 9. There will be adequate light and air in and around the one-story,open pool complex. 10. There is a full complement of public services to accommodate the facility. 11. The subject site is not located in the Urban Center Design Overlay area and is not subject to those special regulations. 12. Section 4-9-200E1k provides "Additional Special review Criteria for COR Zone Only:" and those in part include: 1. The plan is consistent with the Planned Action Ordinance, if applicable. 2. The plan creates a compact,urban development that includes a compatible mix of uses where appropriate. 3. The plan provides an overall urban design concept that is internally consistent and harmonious with development on adjacent sites. 4. The plan incorporates public and private open spaces to provide adequate area for passive and active recreation by the occupants/users of the site and/or protecting existing natural systems. 5. The plan provides view corridors to the shoreline areas where applicable. 6. Public access is provided to water and/or shoreline areas. 7. The plan provides distinctive focal points such as public area plazas,prominent architectural features or other items. 8. The plan assures adequate access to public streets. 9. The plan accommodates and promotes transit,pedestrian and other alternative modes of transportation. 13. The Aquatic Center proposal does not need a"Planned Action Ordinance." 14. The Aquatic Center is part of an urban park system. It contains,as a park should,open space. It is not an inherently compact urban proposal but concentrates many of Renton's community recreation facilities in Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 9 this one location. 15. The entire park concept has been developed to be homogeneous. While new elements such as the pool complex and the Community facility are or have been added,they are designed to blend with the existing park and facilities including the Carco Theater. Development around the site is sparse with I-405 and the Cedar River providing the most defined uses and the cement plant being phased out over the next few years. 16. The park provides its own open space unlike a private development proposal. The immediate pool complex provides the open water pools and two smaller buildings. The new complex should not affect the existing natural systems,which would be the Cedar River and the underlying drinking water aquifer. 17. The proposed aquatic complex should not severely impact any view corridors. Other buildings are already located between the Maple Valley Highway and the Cedar River. In addition,nothing about the new complex would detract from current access to the river and it's viewing and seating areas. 18. The aquatic center probably will become a new focal point for the Cedar River Park in itself. The entire recreational complex,though, serves this function. Hopefully, a more aesthetic fencing arrangement can further enhance the complex's prominent features. 19. The park's location at the intersection of the Maple Valley Highway and I-405 should assure access to public streets. The wall of I-405 and the Cedar River limit access but the City has managed two points of access,which seems appropriate. Two points of access also limits the number of driveways within the park system making it more internally user friendly. 20. The site is adjacent to the Cedar River trail system as well as the state and interstate highway system. Access should be reasonable. 21. Finally,another set of criteria,those for a Level I Site Plan(Section 4-9-200F),must be reviewed. Some of the criteria overlap those reviewed above. The criteria contain the following provisions: 1. Review of Impacts to Surrounding Properties and Uses. 2. Review of Impacts of a Proposed Site Plan to the Site. 3. Review of Circulation and Access. 4. Review of Signage. 5. Special Review Criteria for Hazardous Waste Treatment and Storage Facilities. 6. Review of Street Frontage Landscape. 22. Again,the development of the new aquatic complex should not impair the use of any surrounding properties or uses. It should not bring unnecessary traffic to the area and such traffic would be limited, after construction,to passenger vehicles in the main. The hours will generally not conflict with peak hour traffic demands. The buildings and pools have been located so as not to impact adjacent park or non-park uses. The design,as a whole, should enhance the general look of the campus and is designed to appear to be part of the existing campus. Renton Aquatic Center File No.: LUA-02-147,SA-H,ECF February 25,2003 Page 10 23. As already noted,the development will decrease the open space at this park. That seems a justifiable balancing of the interests inherent in creating a summer swimming venue at an existing,centrally located park facility. The applicant has minimized the intrusions but some loss will occur. 24. The two points of access are pretty well defined by the location and existing development pattern of a parcel located in the southeast quadrant of the I-405/Maple Valley Highway intersection. The main, signalized intersection will provide reasonable access to all points of the City. The secondary Houser Way tunnel is a limited but available route that has served reasonably well. The combination has limited the number of entrances and maintained parkland. The applicant has provided for internal vehicular and pedestrian circulation. A drop-off will provide a safety zone for arriving vehicles dropping off pedestrians. 25. The Park already has signs. As staff noted,any new signs would meet the City's own requirements. 26. While some chemicals for treating the pool might be considered hazardous,their number and quantity will be limited. Staff reported that they would be below triggering thresholds of the Aquifer Protection Ordinance. They would also be stored in legal forms and containers. 27. The applicant will not be altering any of the landscaping found along the streets adjacent to the subject site. Some ten larger,mature trees will be removed to accommodate the proposal but these are not frontage trees. Internal landscaping as well as the leisure pool will serve as both landscape and water elements for the new aquatic center. 28. In conclusion,the proposed Aquatic Center appears to be a well-designed complex in its own right but also will be well integrated into the existing facilities located at Cedar River Park. It will replace a solely missed element;the now closed Henry Moses Pool, in summer fun in the City. Recommendation: The City Council should approve the Site Plan for the City of Renton Aquatic Center subject to the following conditions: 1. The applicant shall comply with the conditions imposed by the ERC. 2. If the City can fund an upgrade to make the fencing of this gateway site more aesthetically pleasing it should do so while,clearly,not compromising the safety and security of patrons and the complex itself.

PROJECT DESCRIPTION/BACKGROUND The applicant is requesting Environmental (SEPA) Review and Hearing Examiner/City Council Site Plan Review approval for the construction of a new City operated aquatic center, which would be located within the Cedar River Park recreational area. The proposed aquatic center is planned to be constructed in the northeast corner of the site, currently utilized as an existing ball field and picnic area. The project is located within the Center Office Residential (COR) zoning and comprehensive plan designation area. The proposed Aquatic Center would include a 9,520 square foot leisure pool, 3,837 square foot lap pool and 6,500 square feet of changing rooms and concession areas. Activities with this proposal would include recreational use, swim lessons, therapeutic uses and occasional swim meets. Construction is planned to begin in April of 2003 and be substantially completed by December of 2003. Once the project is completed, the City is expecting to operate the pool from Memorial Day through Labor Day (weather permitting). Typical hours of operation would be from dusk until dawn (it should be noted that specific pool hours have not been established as of the writing of this report). Access to the site is proposed from two locations. The primary access point is proposed from Maple Valley Highway, which is located directly north of the subject site. Secondary access to the proposed use HEXRPT.doc City of Renton P/B/PW Department liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 4 of 14 is from Houser Way North, which is located west of the subject site. The Cedar River Park site currently contains the Renton Community Center building, Carco Theater, several sport fields and a picnic area, all of which will remain as part of this proposal. In addition, the site has approximately 400 parking stalls, which are proposed to be shared by all uses. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21 C, 1971 as amended), on January 21, 2003 the Environmental Review Committee issued a Determination of Non-Significance- Mitigated, for the project. The DNS-M included six mitigation measures. A 14-day appeal period commenced on January 24, 2003 and ended on February 10, 2003. No appeals of the threshold determination were filed 3. COMPLIANCE WITH ERC MITIGATION MEASURES i Based on an analysis of probable impacts from the proposal, the Environmental Review Committee (ERC) issued the following mitigation measures with the Determination of Non-Significance-Mitigated: 1. Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. 6. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per square foot of new commercial building area prior to the issuance of building permits. 4. STAFF REVIEW COMMENTS Representatives from various city departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH GENERAL SITE PLAN APPROVAL CRITERIA As per RMC 4-9-200E, "The Reviewing Official shall review and act upon site plans based upon comprehensive planning considerations and the following criteria. These criteria are objectives of good site plans to be aimed for in development within the City of Renton. However, strict compliance with any HEXRPT.doc City of Renton P/B/PW Department iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 5 of 14 one or more particular criterion may not be necessary or reasonable. These criteria also provide a frame of reference for the applicant in developing a site, but are not intended to be inflexible standards or to discourage creativity and innovation. The site plan review criteria include, but are not limited to, the following": (A) CONFORMANCE WITH THE COMPREHENSIVE PLAN, ITS ELEMENTS & POLICIES The Comprehensive Plan Land Use Map designation for the project property is Center Office Residential (COR). The purpose of the "Center Office Residential" designation is to provide a mix of intensive office, hotels and convention centers and residential activity in a high-quality master planned development, that is integrated with the natural environment. The following Comprehensive Plan policies are applicable to the proposal: Objective LU-U. Encourage projects throughout the designation which create cohesive, quality and landmark developments integrated with natural amenities. The intention is to create a compact, urban development with high amenity values that is a gateway to the City. The proposed aquatic center has been designed and situated on the site to appropriately interact with the surrounding environment, in addition to being a visible landmark within a gateway corridor to the City. Staff fully expects the proposed aquatic center to be a"high value amenity"to the City. Policy LU-125. Commercial uses such as retail and services should also be permitted provided that they support the primary uses of the site and are architecturally integrated into the development. The proposed aquatic center has been architecturally designed to be integrated into the existing Cedar River Park via locating the aquatic use in an underutilized location of the site. Furthermore, the aquatic center is expected to augment the existing Cedar River Park (recreational) use by providing additional aquatic recreational uses on site. Policy LU-133. Internal site circulation should be primarily pedestrian oriented. The subject site contains approximately 400 existing on-site parking stalls. The applicant has proposed to provide extensive pedestrian circulation from both the parking areas and the main entrance (Maple Valley Highway) to the proposed aquatic center. The pedestrian circulation would primarily utilize existing sidewalks and walkways; however, the applicant has also proposed to provide additional stripping within the existing parking areas. Policy LU-134. Vehicular access to each proposed development should be from a major street with the number of access points reasonably minimized. Access to the proposed aquatic center would be provided primarily from Maple Valley Highway. Secondary access would be provided from Houser Way North (right in/right out), through the existing Cedar River Park site. (B) CONFORMANCE WITH LAND USE REGULATIONS The subject site is zoned Center Office Residential (COR). The COR zone was established to provide for a wide variety of uses including commercial, residential, entertainment and personal/professional services. The CD zone allows aquatic center uses (recreational/existing parks) uses as primary permitted uses within this zone. Development Standards The subject site is located in the Commercial Office Residential land use designation. The following standards apply to project proposed within this land use designation: Lot Coverage—The maximum lot coverage allowed in the COR zone is 65% for projects without ; structured parking. In this case, the additional 6,500 square feet of building area (not including the pools) brings the total lot coverage of the site to 6.5% (51,000 square feet of existing building area + 6,500 square feet of new building area = 57,500 total building square feet / 877,762 total site square feet=6.5%), well below the maximum lot coverage allowed within the zone. HEXRPT.doc City of Renton P/B/PW Department _'iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 6 of 14 Setbacks/Landscaping—The minimum and maximum setbacks are determined through the site plan review process. In this case, the proposed aquatic center is located over 100 feet from Maple Valley Highway (front yard) and over 500 feet from the Cedar River (rear yard). In addition, the proposal is located approximately 480 feet from Houser Way North (side yard along a street) and 160 feet to the eastern property line (interior side yard). Staff anticipates that the proposed setbacks would adequately mitigate any concerns from neighboring properties. The COR development standards also prescribe a minimum landscape area along freeway frontages. In this case, a 10-foot landscaped setback from Maple Valley Highway would be required. However, the required landscaping is already in place as part of the existing Cedar River Park. Staff does not recommend any additional freeway frontage landscaping as part of this development. It should be noted that the construction of the aquatic center would require the removal of one Big Leaf Maple tree and nine Pin Oak trees. In addition, all the play field grass within the project area would be removed. However, once the aquatic center is constructed, the applicant has proposed to plant ornamental trees, shrubs and ground cover around the perimeter of the aquatic center. Furthermore, all disturbed ball field grass, outside of the project area, would be replanted once the aquatic center is constructed. Height — The COR zone allows a maximum building height of 10 stories or 125 feet. The maximum height associated with the proposed aquatic center is 19 feet (concession and changing room buildings), which is well below the maximum allowed height within this zone. Parking, Loading, and Driveway Regulations — The City of Renton's parking development standards do not specifically list out aquatic recreation as a use within the prescribed parking ratios. The closest use within the parking table is outdoor and indoor sports arenas, auditoriums, stadiums, movie theaters and entertainment clubs. Those uses require one parking stall per 100 square feet of floor area or one parking stall per every four fixed seats. The following table outlines the required parking: Use Formula Required Provided Community Center 1 stall per 100 square feet 354 354 Carco Theater 1 stall per every 4 fixed seats 75 46 Aquatic Center 1 stall per 100 square feet 266 N/A Total 695 400 However, the applicant has requested an Administrative Parking Modification, which was granted on January 27, 2003. The approval was based on supporting documentation, which demonstrated that one stall per 100 square feet of aquatic center area was in excess of the actual parking demand generated from this type of use. In addition, the City's consultant successfully demonstrated peak parking demand for each use within the site would be at different times for different uses (i.e. theater parking would be at night, while aquatic center parking would be during the day). The aquatic center would be accessed from existing entrance points along Maple Valley Highway (primary) and Houser Way North (secondary limited to right in/right out). No new access points are planned as part of this development. The existing parking configuration conforms to the minimum requirements for drive aisle dimensions and the provision of ADA accessible parking stalls. Staff does not recommend any changes to this area of the site nor are any proposed. Urban Center Design Overlay Regulations The subject site is located outside of the Urban Center Design Overlay Regulations; therefore, they are not applicable to this project. (C) MITIGATION OF IMPACTS TO SURROUNDING PROPERTIES AND USE The proposal is located within the existing City of Renton Cedar River Park site, which is located between Maple Valley Freeway and the Cedar River. As the subject area is currently utilized for H EXRPT.doc City of Renton P/B/PW Department _liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 7 of 14 recreational activities (existing ball field and picnic area), staff does not anticipate the proposed aquatic center use (also recreational) to impact the surrounding properties. In addition, the project site is surrounded by designated state highways (SR169), roads (Houser Way North) and a commercially zoned property, which is currently being utilized as a cement batch plant (to be decommissioned in the near future). Construction activities would result in short-term noise, dust and traffic impacts on surrounding properties. These impacts would be limited to the construction phase of the project, which is estimated to be have a total duration of approximately 10 months (March 2003 to December 2003). The applicant would be required to submit a Construction Mitigation Plan outlining measures to be employed for minimizing dust, noise and traffic impacts during construction prior to the issuance of any building or construction permit. Potential short-term noise and traffic impacts would result from the initial construction of the project. Existing code provisions that limit construction work hours, and requiring the applicant to provide a construction mitigation plan would also mitigate these impacts. (D) MITIGATION OF IMPACTS OF THE PROPOSED SITE PLAN TO THE SITE A geotechnical report prepared by Associated Earth Sciences, Inc. dated December 2002 was j submitted with the project application. The report indicates the site slopes very gently (less than 5%) towards the Cedar River located approximately 700 to 800 feet to the southwest of the most northern property boundary. The reports states that the subsurface conditions consist of 6-inches of sod and topsoil. Beyond the sod and topsoil, the alluvium consists of silty to clean sand and gravel. In general, the upper horizon of the alluvium was loose to medium dense silty sand. The report concludes that the site is suitable for the proposed development. Only minor post- construction settlement of the underlying material due to the superimposed building loads is anticipated. Potential erosion impacts that could occur during project construction would be adequately mitigated by the five erosion control mitigation measures imposed on the project by the City's Environmental Review Committee. In addition to existing City Code requirements for approval of a Temporary Erosion and Sedimentation Control Plan (TESCP) pursuant to the King County Surface Water Design Manual (KCSWDM) and an approved Construction Mitigation Plan prior to issuance of Construction Permits. The subject site is located within the Aquifer Protection Area (APA) and some typically associated swimming pool chemicals would be kept on site. However, staff has verified the amount and type of chemicals required to operate the aquatic center are below the maximum allowed quantities permitted in this APA zone. (E) CONSERVATION OF AREA-WIDE PROPERTY VALUES The proposed aquatic center development is expected to increase property values in the vicinity of the site. Moreover, providing additional recreational opportunities in an area of the City that already provides many recreational activities would only attract more individuals to this area of the City. Staff expects the aquatic center to attract more patrons to this area of the City, which may add value to surrounding commercial properties as demand for additional goods and services are generated. Therefore, over the long-run, existing commercial property values in the immediate vicinity of the project site would be enhanced. (F) SAFETY AND EFFICIENCY OF VEHICLE AND PEDESTRIAN CIRCULATION A traffic study was not required as part of this proposal as staff concluded that the City had adequate traffic flow information on file. In addition, the site is currently being utilized as a recreational destination, which the proposed aquatic center would not change; therefore, additional traffic analysis was determined not to be necessary. As indicated previously, the project is not proposing to provide additional parking stalls. Instead, the applicant has requested to utilize the subject site's approximately 400 existing parking stalls, which provide adequate aisle widths and back-out distances for safe and efficient vehicular HEXRPT.doc City of Renton P/B/PW Department iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 8 of 14 circulation. Nevertheless, the applicant has elected to provide additional pedestrian striping, which would facilitate safe pedestrian circulation throughout the existing parking area to the proposed aquatic center. In addition, the project would utilize an existing walkway from Maple Valley Highway to the subject aquatic center area, which would actively keep pedestrians outside the traffic flow of vehicles entering or exiting the property. Construction truck hauling hours are limited to between 8:30 a.m. to 3:30 p.m. under the Development Guidelines Ordinance in order to avoid conflicts with peak hour traffic. The Traffic ' Planning Section will review construction-related impacts prior to issuing final construction permits. (G) PROVISION OF ADEQUATE LIGHT AND AIR The proposed aquatic center is largely comprised of outdoor swimming pool areas with associated swim decks; thereby allowing adequate light and air circulation throughout the project site. However, the applicant is proposing 6,500 square feet dedicated to changing rooms and concession areas for aquatic center patrons. These one-story structures (approximately 19 feet high) would be located in the southwest corner of the project site. Staff does not anticipate that the one-story buildings would block light and air to the mostly outdoor facility. (H) MITIGATION OF NOISE, ODORS AND OTHER HARMFUL OR UNHEALTHY CONDITIONS It is anticipated that the most significant noise, odor and other potentially harmful impacts would occur during the construction phase of the project. The applicant would be required to submit a Construction Mitigation Plan that provides measures to reduce construction impacts such as noise, control of dust, traffic controls, etc. prior to any construction/building permits being issued. The proposed development would not generate any harmful or unhealthy conditions. There would be noise impacts including increased traffic and activity that are normally associated with a recreational use. In addition, all stored swimming pool chemicals would be kept in a secure and contained area and only the minimum amount necessary to operate the pool would be kept on site. Nevertheless, minor pool treatment chemical smells (typically associated with a swimming pool) may be present during normal operation of the aquatic center. However, staff does not anticipate the amount of chemicals used to operate the pool to be harmful or cause unhealthy conditions. (I) AVAILABILITY OF PUBLIC SERVICES AND FACILITIES TO ACCOMMODATE THE PROPOSED USE Fire Department and Police staff have indicated that the City's existing facilities and resources are adequate to accommodate the subject proposal, provided that the applicant pay the appropriate Fire Mitigation Fee. Therefore, the City's Environmental Review Committee required the applicant to pay a Fire Mitigation Fee in the amount of $0.52 per square foot of new commercial building area. In addition, the City's Public Works department has indicated there are sufficient utilities in the area to serve this development and that the existing street system is adequate for this type of project. (J) PREVENTION OF NEIGHBORHOOD DETERIORATION AND BLIGHT The proposal would enhance an existing recreational area of the City via incorporating a family aquatic center into an existing recreation destination. Staff fully anticipates that the City's investment in the area would serve to prevent neighborhood deterioration and blight. Furthermore, the increase in recreational uses to this area of the City would generate more demand for additional goods and services, which other commercial property owners in this vicinity of the City may benefit from. (K) CONSISTENCY WITH ADDITIONAL COR SITE PLAN APPROVAL CRITERIA Per RMC 4-9-200E1 k, "Additional Special review Criteria for COR Zone Only:" the following items must be reviewed when a site plan review application is being conducted within the COR zone: H EXRPT.doc City of Renton P/B/PW Department liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 9 of 14 1. The plan is consistent with the Planned Action Ordinance, if applicable: This requirement is not applicable as the subject proposal did not require a Planned Action Ordinance. 2. The plan creates a compact, urban development that includes a compatible mix of uses where appropriate: The aquatic center is proposed to be located in an existing recreational area of the City. The aquatic center (recreational use) is proposed to replace a portion of the existing sports ball fields and picnic area currently located within the Cedar River Park site. As the proposed use is recreational, staff anticipates that the project would be compatible with the existing uses on site. 3. The plan provides an overall urban design concept that is internally consistent and harmonious with development on adjacent sites: As the Cedar River Park site is surrounded by the Maple Valley Highway to the north, the Cedar River to the south, Houser Way North to the west, and a cement batch plant to the east (to be decommissioned in the near future), staff does not anticipate the proposed aquatic center to be incompatible with the neighboring sites. In addition, the aquatic center recreational use is proposed on the existing Cedar River Park site, which is already utilized as a recreational destination within the City of Renton. 4. The plan incorporates public and private open spaces to provide adequate area for passive and active recreation by the occupants/users of the site and/or protecting existing natural systems: The proposed aquatic center would be located on the existing Cedar River Park site, which already provides open space for both passive and active recreation. The aquatic center would provide additional active recreational opportunities within the Cedar River Park property. Furthermore, the proposed aquatic center (recreational) use would be located over 500 feet from the Cedar River. The existing natural river system would not be adversely affected. 5. The plan provides view corridors to the shoreline areas where applicable: The subject aquatic center would be located over 500 feet from the Cedar River; therefore, views to the shoreline would not be obstructed. It should also be noted that the location of the Community Center Building and the Carco Theater Building block some of the view corridors within the Cedar River Park to the Cedar River. 6. Public access is provided to water and/or shoreline areas: The aquatic center has been designed to provide water-swimming activities for residents throughout the area. In addition, the project has been located such that it would not impede citizens from reaching the Cedar River shorelines, where existing access is already granted within the Cedar River Park site. 7. The plan provides distinctive focal points such as public area plazas, prominent architectural features or other items: The aquatic center has been designed as a public outdoor water theme park, which provides a focal point and a public area within an existing community park. 8. The plan assures adequate access to public streets: The aquatic center has been designed to utilize two existing access points, which lead to public streets. Primary access would be provided from Maple Valley Highway, which is located north and east of the proposed aquatic center and has a full turning movement intersection regulated by a traffic signal. Secondary access would be provided from Houser Way North, which is located west of the subject site and is limited to signalized right in/right out turn only. 9. The plan accommodates and promotes transit, pedestrian and other alternative modes of transportation: The proposed aquatic center is located along a state route, which would provide adequate vehicular access to the site. In addition, this area of the City is located near other recreational uses (i.e. Liberty Park, Cedar River Trail), which would allow pedestrians to easily walk to the site. Furthermore, the applicant has proposed to clearly stripe pedestrian pathways from the existing parking area within the Cedar River Park site to the aquatic center, which would ensure safe pedestrian circulation throughout the site. (L) ADDITIONAL REVIEW CRITERIA FOR LEVEL I SITE PLANS As per RMC 4-9-200F, "Additional Review Criteria For Level I Site Plans"the following items must be reviewed when a Level I site plan review application did not previously undergo a Level II Site Plan Review process: HEXRPT.doc City of Renton P/B/PW Department iminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 10 of 14 1. Review of Impacts to Surrounding Properties and Uses: a. Mitigation of undesirable impacts of proposed structure and site layouts that could impair the use or enjoyment or potential use of surrounding uses and structure and of the community: Staff does not anticipate the proposed aquatic center to impair the use or enjoyment of the existing Cedar River Park site. Conversely, staff anticipates that the proposed aquatic center would enhance the existing recreational opportunities currently undertaken within the Cedar River Park site. b. Mitigation of undesirable impacts when an overscale structure, in terms of size, bulk, height, and intensity, or site layout is permitted that violates the spirit and/or intent of the Zoning code and impairs the use, enjoyment or potential use of surrounding properties: The majority of the proposed aquatic center is comprised of open-air swimming areas, which would not be out of scale with the surrounding area. In addition, the 6,500 square feet of proposed new concession and changing room areas is limited to one-story and is not expected to impact adjacent properties. Finally, the structures are setback over one- hundred feet from the neighboring property to the east, which is currently utilized as a cement batch plat(to be decommissioned in the near future). c. Provision of a desirable transition and linkage between uses and to the street, utility, walkway and trial systems in the surrounding area by the arrangement of landscaping, fencing and/or other buffering techniques, in order to prevent conflicts and to promote coordinated and planned benefit from and access to such elements: The aquatic center has been located such that pedestrians walking from Maple Valley Highway would have direct pedestrian pathway access to the proposed aquatic area. Furthermore, the applicant has proposed to stripe new pedestrian walkways within the existing parking area, in order to provide a safe and efficient pedestrian pathway from the existing parking lot to the aquatic center entrance. d. Consideration of placement and scale of proposed structures in relation to the natural characteristics of a site in order to avoid overconcentration of structures on a particular portion of a site such that they create a perception of greater height or bulk than intended under the spirit of the Zoning Code: The aquatic center use is proposed to be located in a flat area of the Cedar River Park site in order to minimize the amount of grading required for the below-grade swimming pools. In addition, the applicant has elected to locate the aquatic center over 500 feet from the Cedar River in order to avoid any negative impacts to that water body. Finally, the proposed aquatic center buildings would be located several hundred feet from the community center building and the Carco Theater. Therefore, staff does not expect the aquatic center use to overconcentrate both the existing recreational opportunities and the existing buildings within the Cedar River Park site. e. Effective location, design and screening of parking and service areas in order to promote efficient function of such facilities, to provide integrated facilities between uses when beneficial, to promote `campus-like" or `park-like" layouts in appropriate zones and to prevent unnecessary repetition and conflict between uses and service area or facilities: The applicant is proposing to utilize the existing parking lot, which would be located behind the proposed aquatic center area. As the site is currently utilized for outdoor recreational opportunities, the applicant has attempted to locate the aquatic center in such a manner that provides additional recreational opportunities for citizens. Finally, staff expects the addition of an aquatic center within the Cedar River Park to enhance the existing "park-like"atmosphere that presently exists. f. Mitigation of the unnecessary and avoidable impacts of new construction on view from existing buildings and future developable sites, recognizing the public benefit and desirability of maintaining visual accessibility to attractive natural features and of promoting `campus-like" or "park-like" setting in appropriate zones: The proposed aquatic center use is comprised of mostly open-air swimming areas, which would not restrict views from existing buildings or future development. The 6,500 square feet of proposed concession and changing room areas is limited to one-story and would be less than 20 feet in height. Because the proposed structures are located towards the HEXRPT.doc City of Renton P/B/PW Department 'minary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 11 of 14 northern boundaries of the site (500 feet from the Cedar River) and are limited to one story in height, staff does not anticipate the structures to block future or existing views of the Cedar River. g. Provision of effective screening from public streets and residential uses for all permitted outdoor storage areas (except auto and truck sales), for surface mounted utility equipment and for all refuse and garbage containers, in order to promote a "campus-like" or"park-like"setting where appropriate and to preserve the effect and intent of screening or buffering other wise required by the Zoning Code: The applicant has proposed to utilize the existing screened refuse and garbage containment system currently in operation within the Cedar River Park site. No additional outdoor storage areas or surface mounted utility equipment have been proposed. h. Consideration of placement and design of exterior lighting in order to avoid excessive brightness or glare to adjacent properties and streets: The applicant has proposed eight pole mounted lights, which would be located throughout the aquatic center site. In addition, there would be several wall-mounted lights along the interior of the concession and changing room-building walls. According to the lighting plan submitted with the building permit applicant, each light would be shielded and focused downward onto the property within the aquatic center area. As the aquatic center site is located over 100 feet from the nearest property boundary, staff does not anticipate any light spillage to occur outside of the Cedar River Site. In addition, staff does not expect any light spillage to occur within the Cedar River, as the proposed aquatic center is over 500 feet to the north of the river. However, the applicant contends that the lighting plan would provide enough lighting to adequately illuminate the site for safety and security purposes. 2. Review of Impacts of a Proposed Site Plant to the Site: a. Building Placement and spacing to provide for privacy and noise reduction; orientation to views and vistas and to site amenities, to sunlight and prevailing winds and to pedestrian and vehicle needs: The majority of the proposed aquatic center is comprised of open-air swimming areas, which are not expected impede sunlight and the prevailing winds. The 6,500 square feet of new buildings are limited to one-story in height and are not expected to shade or block the sun and prevailing winds within the site. Privacy and noise reduction are not relevant in this situation as the proposed use in an open-aired aquatic center, within an existing recreational site. b. Consideration of placement and scale of proposed structures in relation to the openness and natural characteristics of a site in order to avoid overconcentration of the impression of oversized structures: As the proposal is for an open-aired aquatic center with very little new building space, staff does not expect an overconcentration of buildings or oversized appearing structures to occur within the Cedar River Park site. As noted previously, the majority of the site would remain open and in a more natural state, staff anticipates a lot coverage of 6.5% upon project completion. c. Preservation of the desirable natural landscape through retention of existing vegetation and limited soil removal, insofar as the natural characteristics will enhance the proposed development: The applicant has elected to locate the proposed aquatic center in a relatively flat area of the Cedar River Park site, which should minimize the amount of grading. However, the swimming pools are proposed to be below grade, which would require excavation regardless of the natural characteristics of the site. It should also be noted that the aquatic center is proposed to be located over 500 feet from the Cedar River, which was intended to preserve the natural landscape in that area of the Cedar River Park site. However, some of the existing trees and landscaping would be removed as part of this proposal. d. Use of existing topography to reduce under cutting, filling and retaining walls in order to prevent erosion and unnecessary storm water runoff and to preserve stable natural slopes and desirable natural vegetation: The applicant has elected to locate the proposed aquatic center in a relatively flat area of the site, which should minimize the amount of grading required. However, as the proposal is for a below-grade swimming area, HEXRPT.doc City of Renton P/B/PW Department . ._liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 12 of 14 excavation would be necessary. The City's existing erosion control measures along with the Environmental Review Committee mitigation measures would alleviate any stormwater/erosion control issues. e. Limitation of paved or impervious surface, where feasible, to reduce runoff and increase natural infiltration: The proposed aquatic center has been designed to minimize the amount of impervious surface created by locating the use within a developed site. Moreover, the applicant has elected to locate the aquatic center within a site that already contains impervious parking and walkway areas, so no additional vehicular related impervious areas have to be created. Furthermore, the applicant has elected to locate pervious planting areas wherever practical throughout the aquatic center site, which would limit the amount of impervious area created as part of this development proposal. f. Design and protection of planting areas so that they are not susceptible to damage from vehicles or pedestrian movements: The area within the Cedar River Park where the aquatic center use is proposed is mainly comprised of field grass and ornamental oak trees. Once the aquatic center is constructed, the existing roadways and pedestrian access points within the Cedar River Park site would be utilized to access the aquatic center. In addition, the areas surrounding the aquatic center use are mainly comprised of field grass and ornamental trees. It should be noted that some of the ornamental trees would be removed as part of this proposal; however, the applicant has elected to locate several planting areas throughout the aquatic center site were ever practical. g. Consideration of building form and placement and landscaping to enhance year-round conditions of sun and shade both on-site and on adjacent properties and to promote energy conservation: The majority of the aquatic center use is comprised of open-air swimming areas, which would only be utilized during warm weather conditions. Therefore, staff does not expect the proposed use to impact adjacent properties nor negate energy conservation. 3. Review of Circulation and Access: a. Provision of adequate and safe vehicular access to and from all properties: As this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. b. Arrangement of the circulation pattern so that all ingress and egress movement may occur at as few points as possible along the public street, the points being capable of channelization for turning movements: As this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. c. Coordination of access points with adjacent properties, when feasible: This is not feasible as this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. d. Coordination of access points on a superblock basis so that vehicle conflicts and vehicle/pedestrian conflicts are minimized: As this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. e. Orientation of access points to side streets or frontage streets rather than directly onto arterial streets, when feasible: This is not feasible as this proposal is only adding additional recreational uses within the existing Cedar River Park site, the applicant has not proposed to modify the existing access points or internal circulation patterns. f. Promotion of the safety and efficiency of the internal circulation system, including the location, design and dimensions of vehicular and pedestrian access points, drives, parking, turnarounds, walkways, bikeways and emergency access ways: This is not feasible as this proposal is only adding additional recreational uses within the existing Cedar River Park site. The applicant has not proposed to modify the existing access HEXRPT.doc City of Renton P/B/PW Department _liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 13 of 14 points or internal circulation patterns. In addition, the applicant has proposed to utilize the existing parking areas within the Cedar River Park site, which meet current safety requirements. g. Separation of loading and delivery areas from parking and pedestrian areas: There are no loading or delivery areas proposed with the aquatic center use. h. Provisions for transit and carpool facilities and access here appropriate: The aquatic center has been designed to accommodate vehicles entering the site and having the ability to drop-off passengers near the main entrance of the aquatic center. The drop-off point is located toward the southeast corner of the aquatic center, which would provide for fast, efficient and safe drop-off capabilities. i. Provision for safe and attractive pedestrian connection between parking areas, building, public sidewalks and adjacent properties: The applicant has located the proposed aquatic center use such that existing pedestrian pathways from Maple Valley Highway would be utilized from individuals walking to the site. In addition, the applicant has proposed to stripe the existing parking area, in order to clearly denote the pedestrian pathway to the proposed aquatic center from the parking areas. 4. Review of Signage: a. Employment of signs primarily for the purpose of identification: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. b. Management of sign elements, such as size, location, and arrangement so that signs complement the visual character of the surround area and appear in proportion to the building and site to which they pertain: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. c. Limitation of the number of signs to avoid visual clutter and distraction: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. d. Moderation of surface brightness or lighting intensity except for the necessary for sign visibility: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. e. Provision of an identification system to allow for quick location of buildings and addresses: No additional signage is proposed at this time; however, when proposed all signage would need to meet the City's Sign Code requirements. 5. Special Review Criteria for Hazardous Waste Treatment and Storage Facilities: a. Above-ground hazardous waste treatment and storage facilities shall be constructed with containment controls, which will prevent the escape of hazardous waster in the event of an accidental release from the facility. Such controls shall conform with all adopted Federal, State and local design and construction standards: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). b. Underground hazardous waste treatment and storage facilities shall comply with RMC4-5- 120, Underground Storage Tank Secondary Containment Regulations: The proposal does not include any hazardous waste treatment and/or storage facilities. c. Hazardous waste treatment and storage facilities shall comply with article 80 of the Uniform Fire Code as adopted by ordinance by the City of Renton: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). HEXRPT.doc City of Renton P/B/PW Department _liminary Report to the Hearing Examiner RENTON AQUATIC CENTER LUA-02-147, SA-H, ECF PUBLIC HEARING DATE:February 18,2003 Page 14 of 14 d. A hazardous waste spill contingency plan for immediate implementation in the event of a release of hazardous wastes at the facility shall be reviewed and approved by the Renton Fire Department prior to issuance of any permits: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). e. The location of all on-site and off-site facilities must comply with the State siting criteria as adopted in accordance with RCW70-105.210: The proposal does not include any hazardous waste treatment and/or storage facilities (with the exception of the swimming pool treatment chemicals, which are proposed to be below the maximum permitted within the APA zone). 6. Review of Street Frontage Landscape: a. A mix of hard surfaces, structured planters, and terraces may be incorporated into street frontage landscape buffer where such features would enhance the desired streetscape character for that particular neighborhood: The subject proposal is located adjacent to Maple Valley Highway and Houser Way North. As those areas have sufficient landscaping, staff does not propose any additional landscaping to occur at this time. However, additional internal landscaping as part of the aquatic center development is proposed. This landscaping would mainly consist of ornamental planting areas located within the aquatic park. H. RECOMMENDATION: Staff recommends approval of the City of Renton Aquatic Center Site Plan Review Application, Project File No. LUA-02-147, SA-H, ECF.

The subject site is currently utilized by the City of Renton as the Cedar River Park, which contains the Community Center building, Carco Theater and ball fields. The proposed aquatic center triggers the site plan application referenced above and also requires a parking modification. The applicant has indicated that the subject site currently contains approximately 400 parking stalls, which is 295 spaces short of the minimum number of stalls required for all uses (Community Center building, Carco Theater and the proposed aquatic center use). It should be noted that the subject site, prior to the proposed aquatic center addition, is currently 29 parking stalls short of the minimum required by code. Nevertheless, the applicant has requested a parking modification with the site plan application. Section 4-4-080Fd allows the Planning/Building/Public Works Department to grant modifications from the parking standards for individual cases provided that the modification meets the following criteria (pursuant to RMC 4-9-250D2): a. Will meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment; and b. Will not be injurious to other property(s) in the vicinity; and c. Conforms to the intent and purpose of the Code; and d. Can be shown to be justified and required for the use and situation intended; and e. Will not create adverse impacts to other property(ies) in the vicinity. Background The subject proposal would result in the construction of new outdoor aquatic center. The facility would be comprised of a 9,250 square foot leisure pool, 3,837 square foot lap pool and 6,500 square feet of concession and changing room areas. The property is located in the Center Office Residential (COR) zone and is adjacent to Maple Valley Highway. The site is currently developed with an existing Community Center building, Carco Theater and ball fields, along with supporting utilities, parking, and landscape improvements. Additional parking stalls are not proposed within the Cedar River Park site, thereby increasing the non-conforming parking situation. At present, a total of 400 parking spaces exist within the boundaries of the site. The proposed aquatic center would require an additional 266 parking H:\Division.s\Develop.ser\Dev&plan.ing\PROJECTS\02-147.jason\pkgmod.doc . stalls, resulting in a parking stall shortage of 295 parking stalls (266 aquatic center stalls + current 29 parking stall shortage =295). Section 4-4-080F of the parking regulations require the provision of a specified number of parking spaces based on the specific use of the site. Based on the applicant's parking analysis, the Community Center building contains 35,380 square feet of assembly area, which requires 1 stall per 100 square feet(35,380/ 100 = 354 parking stalls). Carco Theater is comprised of 300 theater seats, which requires 1 stall per every 4 seats (300/4 = 75 parking stalls). Finally, the proposed aquatic center consists of approximately 26,600 square feet of pool, building and deck area, which requires 1 stall per 100 square feet (26,600/ 100 = 266 parking stalls). Therefore, the total number of parking stalls required is 695. The following table also depicts the above- mentioned parking requirements: Use/sf Parking Ratio Required Provided Parking Parking Community Center 35,380 sf 1 stall per 100 square feet 354 354 Carco Theater 300 seats 1 stall per every 4 seats 75 46 Aquatic Center 26,600 sf 1 stall per 100 square feet 266 0 Total 695 400 Because the existing number of stalls is 295 spaces less than the minimum number of stalls required by code, the applicant has included a parking modification request with the site plan application. The approval of the parking modification will be required as a condition of approval for the proposed site plan. In the event the modification request is not approved, the applicant would be required to comply with the parking regulations by either modifying the site plan, or by establishing alternative arrangements (e.g., off-site or shared parking through agreements). In addition, the satisfaction of this requirement would be necessary prior to the issuance of building permits. Analysis 1.) Will meet the objectives and safety,function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment. The applicant's project design team submitted a narrative statement that compared actual parking demand with existing aquatic centers throughout the area. Specifically, the project team determined that the maximum occupancy load associated with the Renton aquatic center would be below 1,000 individuals. The project team concluded that, on average, each vehicle coming to the Cedar River Park to utilize the aquatic center would have 3.5 people per car. The team also concluded that approximately half of the pool users would be dropped-off by family; thus, not requiring a dedicated parking stall. Therefore, the total number of stalls required for the aquatic center would be approximately 142 (500 [half the maximum occupancy load] /3.5 [individuals per car] = 142 dedicated parking stalls). The project team has determined that the aquatic center peak use hours would be at different times than the Community Center and Carco Theater. Specifically, the project team believes the pool peak use hours would be limited to the weekends and during the first two hours of operation during the week (approximately from 10:00 am to 12:00 pm). The swim teams, exercise classes and seniors would utilize the aquatic center in the early morning hours. However, the Community Center building peak use hours are during the evening on weekdays and afternoon on the weekends. Carco Theater is mainly utilized during the evening hours both during the weekdays and weekends. Therefore, the project team anticipates the 400 existing parking stalls within the Cedar H:\Division.s\Develop.ser\Dev&plan.ing\PROJ ECTS\02-147.jason\pkg mod.doc River Park to be adequate to accommodate the additional demand generated from the aquatic center use (approximately 142 stalls during peak pool demand). The code's on-site parking requirements are intended to eliminate parking impacts to surrounding properties. During the aquatic center peak parking demand, 142 stalls would be required out of the 400 existing parking stalls. As peak demand for each use (Community Center, Carco Theater and the aquatic center)would not occur at the same time, staff anticipates the existing 400 parking stalls to be adequate for the proposed aquatic center use. Therefore, the requested modification conforms to the intent and purpose of the parking regulations by providing sufficient on-site parking for each use within the site. The proposal, as depicted on the site plan, appears to meet the objectives and safety, function, appearance, environmental protection and maintainability intended by code requirements, based upon sound judgment. 2.) Will not be injurious to other property(s) in the vicinity. The proposed parking satisfies code requirements for stall width, depth, drive aisles, and emergency access. Based on the applicant's parking modification justification, the site would provide adequate parking for the intended use(s). As peak parking demand for the aquatic center use is expected to occur during non-peak parking demand for the other uses within the park, staff does not anticipate a parking shortage at any one-time. As adequate parking for each use during peak parking demand time would be accommodated, patrons are not expected to park off-site. Therefore, staff does not expect this proposal to be injurious to other properties in the vicinity. Finally, it should be noted that the existing parking situation is currently 29 parking stalls short of the minimum required. However, this substandard situation has not been found to be injurious to other properties in the vicinity. Moreover, the project team has indicated that a parking shortage does not exist because the Community Center and Carco Theater have differing peak parking demand hours. The project team concludes that the addition of the aquatic center would also be harmonious with the existing on-site parking, because it too would have a different peak parking demand than the other existing uses. 3.) Conforms to the intent and purpose of the Code. See discussion under criteria number 1)above. 4.) Can be shown to be justified and required for the use and situation intended. As indicated in the applicant's parking justification, the existing 400 parking stalls are rarely maximized as each use within the Cedar River Park has differing peak parking demand times. Therefore, the existing 400 parking stalls provided are justified for the existing and proposed use(s)and situation at the Cedar River Park. 5.) Will not create adverse impacts to other property(ies) in the vicinity. As stated under criteria number 2)above, the proposed parking would not create adverse impacts to other properties in the vicinity from the Cedar River Park. Recommendation The proposed aquatic center use is expected to generate peak parking demands at differing times than the existing uses within the Cedar River site. According to parking code requirements (RMC 4-4-080F10e)for indoor/outdoor recreational facilities, the proposal would need to provide 295 additional parking stalls. However, based on the parking justification provided by the applicant, staff recognizes that the proposed parking for the site would be adequate for the intended use(s)within the Cedar River Park.

The proposed aquatic center would include a 9,520 square foot leisure pool, 3,837 square foot lap pool and 6,500 square feet of changing rooms and concession areas. Activities with this proposal would include recreational use, swim lessons, therapeutic uses and occasional swim meets. The pool is proposed to be located in the northeast corner of the Cedar River Park, and would be located over 500 feet from the Cedar River; therefore, no shoreline permits are required. The aquatic center would be located within the Aquifer Protection Area Zone One (APA 1). Construction is planned to begin in April of 2003 and be completed by December of 2003. Once the project is completed, the City is expecting to operate the pool from Memorial Day through Labor Day (weather permitting). Access to the site is proposed from two locations, Maple Valley Highway and Houser Way North. LOCATION OF PROPOSAL: 1715 Maple Valley Highway(Cedar River Park) MITIGATION MEASURES: 1. Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4.

Aquifer Protection: 1. See attached Aquifer Protection comments dated January 9, 2003. : r i; • CITY OF RENTON PLANNING/BUILDING/PUBLIC WORKS MEMORANDUM DATE: January 9, 2003 TO: Juliana Sitthidet FROM: Carolyn Boatsman SUBJECT: Renton Aquatics Center The following comments are offered with respect to the protection of the City's drinking water aquifer: I. The proposal includes a well to be used to monitor the groundwater level under the pools. It is proposed that the well would also be used to pump down the aquifer should a pool need to be emptied during a period of water tables high enough to float the pools. The Water Utility has doubts that it would be feasible to establish a groundwater capture-zone large enough to protect the pools in this type of aquifer. We suggest that pools not be emptied during high water. Should this aspect of the proposal go forward, the Utility would require review and approval of the plans and specification for the well and pump to ensure that no negative effects on quality or quantity of drinking water would occur. Documentation of compliance with Department of Ecology well construction requirements would also be required. 2. Review of a preliminary compilation of hazardous materials that will be present on the premises indicates that the total will be equivalent to about 125 gallons (solids converted to liquids at the rate of 10 pounds solid to 1 gallon liquid for counting purposes). This amount is below the 500-gallon maximum quantity allowed in Zone 1 of the Aquifer Protection Area (APA). We reserve final comment on the location of this facility when we have an opportunity to review the Hazardous Materials Inventory Statement requested by the Fire Prevention Bureau. Some items that will likely be listed in the HMIS will be exempt for aquifer protection purposes (janitorial and personal care products, aerosol cans, hazardous materials determined to present no risk to the aquifer, etc.). A final determination as to whether an Operating Permit will be required will also be made when we review the HMIS. 3. The construction mitigation narrative submitted with the proposal does not mention compliance with APA Construction Activity Standards (RMC 4-4-03007). The Utility operates production wells in the immediate vicinity of the project and is concerned regarding typical contaminants that can be introduced during construction such as leaky hydraulics, spill of stored chemicals, etc. Documentation of compliance with the standards should be included in plans and specifications. 4. As a reminder, sewage and stormwater piping and appurtenances shall meet APA Zone 1 specifications contained in RMC 4-3-050S.

The site will need security lighting and any construction trailer should be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. Although the freeway is close by, this area of Renton is very isolated, especially during hours of darkness, and susceptible to criminal activity. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" throw when bolted. Glass windows in the trailer should be shatter-resistant. I recommend the developer post appropriate "No Trespassing" signs on the property (in numerous locations) while it's under construction (appropriate verbiage flier attached). This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. The use of off-duty police officers or private security guards to patrol the site during the hours of darkness is highly recommended. The City should continue the security of this property following construction. COMPLETED BUILDING It's important to direct all foot traffic into the main entrance of the aquatic center. This should be monitored during all hours of business by placing a reception/ticket area in the front of the center, with participant access severely restricted. This will assist with control of the pedestrian traffic in the center's public areas. (Entrance through other exterior doors should be strictly prohibited— this includes employees.) Rules of usage should be posted in conspicuous locations throughout the complex. All doors leading to enclosed structures (i.e., changing rooms, bathrooms, concessions, etc.) should be metal with single-latch deadbolts and latch guards with pry-resistant cylinders around the locks. The outside of these doors should be marked as "Alarmed Door" in red, at least 6 inches in height. Any payphones should be posted away from the changing rooms, and set up at out-going only. The fencing around the pools should be enhanced (for security purposes) with razor Page 1 of 2 PRO` CT LUA 02-147, SA-H, EC.. Aquatic Center City of Renton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET (Continuation) or barbed wire. It should not be expected that criminals will not scale this fence, since chain-link fencing provides more then adequate footing for the climb. It's recommended that an alarm system be installed for those structures which are enclosed, at that the sensors include both motion and door/window contacts. For the exposed portion of the aquatic center, there should be an abundance of lighting provided to deter criminals from entering this area after hours. Surveillance cameras are also recommended for this location, with the focus being on the pool area, changing rooms (outside), and pro shop. Landscaping in and around the exterior of the buildings should not be too dense or high. It is important to allow visibility. Too much landscaping will give the center the Iook of a fortress and possibly give a burglar sufficient coverage to break into the buildings or damage property, especially during the hours of darkness. A business of this size and type needs proper lighting and an abundance of signage. The public needs to be made aware at all times of what space is private and what space is public. Proper No Trespassing signs should be posted in conspicuous locations throughout the outside of the buildings (including parking areas) so enforcement action can be taken if needed. These signs need to have the proper verbiage, which contains the City of Renton Code (see attached.) { Page2of2 Trespass 1r 6.1 _ •Y - !iaeeAf;I3o•nOtt9ro!,l: USINES ' Enforcement WATCH Quite often, business owners and managers are faced with crimes that occur on the property after the businesses are closed and the employees have gone home. Some of the crimes that occur are burglary, vandalism, graffiti, trespassing, drug dealing and robbery in the parking lots. There is a way for police and business owners to discourage these types of crimes from taking place on private property, and that is by enforcing the City of Renton's Municipal Trespass Code 6-18-10. In order for police to be able to make an arrest for Trespass, business owners or managers need to purchase signs and display them in conspicuous areas on the property. These signs need to include the following language: 1. Indicate that the subject property is privately owned and; 2. Uninvited presence on the specified property is not permitted during the hours the business is closed, and; 3. Violators will be subject to criminal sanctions pursuant to Renton City Code 6-18-10. MOST IMPORTANTLY -THE SIGNS SHOULD BE CONSPICUOUS FROM ALL POSSIBLE POINTS OF ENTRY TO THE PROPERTY,AND ALSO BE PLACED ON THE EXTERIOR OF THE BUILDINGS. This way when a suspect is arrested, he/she will not be able to claim as a defense that he/she did not know he or she was trespassing. EXAMPLES FOR TRESPASS SIGNS: NO TRESPASSING NO TRESPASSING This is private property. Persons without specific No Trespassing after business hours business are not authorized to be on the premises (insert specific times). Anyone on the between the hours of (insert the hours your business is premises after business hours is subject closed). to arrest and/or citation for Criminal Violators are subject to arrest and/or citation for Trespass and/or impoundment of criminal Trespass pursuant to Renton City Code#6-18- vehicle. Per Renton City Code #6-18- 10.. 10. By enforcing the Trespass Ordinance, business owners and police will be sending a message to criminals that they are not allowed to conduct criminal activity on the property. In making arrests for Trespass, police may be preventing the more serious crimes from taking place.

Too much landscaping will give the center the look of a fortress and possibly give a burglar sufficient coverage to break into the buildings or damage property,especially during the hours of darkness.

Clarification was also sought at that time as to where ingress and egress from Maple Valley highway was being provided and how pedestrian-oriented circulation was proposed to be handled, especially between the new Aquatics Center and the Community Center complex to the southwest. The applicant has responded in their December 16, 2002 project narrative stating that the current ingress/egress from Maple Valley Highway will remain in effect until access is eventually moved 500 feet to the east when new highway improvements are implemented. No special provisions for pedestrian access are noted. It is apparently assumed that pedestrians, both children and adults, will circulate through the parking aisles between the Community Center and Aquatic Center. The applicants are also requesting a parking modification to reduce the number of required parking spaces. Although the site is relatively isolated by topography and highways/freeways from the rest of the city, the applicant states that they would expect up to half of the users of the new aquatic center to arrive by foot, via skateboards, bicycles, or by auto drop-off. They also believe that for those arriving by auto, the occupancy per vehicle will be an average of 3.5 persons per trip. Recommendation: Continue to support this proposal, again with concerns about the adequacy of pedestrian circulation between facilities as well as the amount of off-street parking proposed for what will essential be a regional outdoor aquatic center. i cc: Don Erickson 1 Document1Vd City of Renton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET REVIEWING DEPARTMENT: (�ytst,�(_-�-`�,,\S�,,vx cej COMMENTS DUE: JANUARY 10, 2003 1 ETCE�rvTON APPLICATION NO: LUA-02-147,SA-H,ECF DATE CIRCULATED: DECEMBER 27,2002 R V C.D APPLICANT: City of Renton, Community Services PROJECT MANAGER: Jason Jordan �� PROJECT TITLE: Aquatic Center WORK ORDER NO: 77077 J 20�?

Signature of Director or Authorized Representative Date routing.doc Rev.10/93 CITY OF RENTON PLANNING/BUILDING/PUBLIC WORKS MEMORANDUM DATE: January 9,2003 TO: Juliana Sitthidet FROM: Carolyn Boatsman SUBJECT: Renton Aquatics Center The following comments are offered with respect to the protection of the City's drinking water aquifer: 1. The proposal includes a well to be used to monitor the groundwater level under the pools. It is proposed that the well would also be used to pump down the aquifer should a pool need to be emptied during a period of water tables high enough to float the pools. The Water Utility has doubts that it would be feasible to establish a groundwater capture-zone large enough to protect the pools in this type of aquifer. We suggest that pools not be emptied during high water. Should this aspect of the proposal go forward, the Utility would require review and approval of the plans and specification for the well and pump to ensure that no negative effects on quality or quantity of drinking water would occur. Documentation of compliance with Department of Ecology well construction requirements would also be required. 2. Review of a preliminary compilation of hazardous materials that will be present on the premises indicates that the total will be equivalent to about 125 gallons (solids converted to liquids at the rate of 10 pounds solid to 1 gallon liquid for counting purposes). This amount is below the 500-gallon maximum quantity allowed in Zone 1 of the Aquifer Protection Area (APA). We reserve final comment on the location of this facility when we have an opportunity to review the Hazardous Materials Inventory Statement requested by the Fire Prevention Bureau. Some items that will likely be listed in the HMIS will be exempt for aquifer protection purposes (janitorial and personal care products, aerosol cans, hazardous materials determined to present no risk to the aquifer, etc.). A final determination as to whether an Operating Permit will be required will also be made when we review the HMIS. 3. The construction mitigation narrative submitted with the proposal does not mention compliance with APA Construction Activity Standards (RMC 4-4-03007). The Utility operates production wells in the immediate vicinity of the project and is concerned regarding typical contaminants that can be introduced during construction such as leaky hydraulics, spill of stored chemicals, etc. Documentation of compliance with the standards should be included in plans and specifications. 4. As a reminder, sewage and stormwater piping and appurtenances shall meet APA Zone 1 specifications contained in RMC 4-3-050S.

The site will need security lighting and any construction trailer should be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. Although the freeway is close by, this area of Renton is very isolated, especially during hours of darkness, and susceptible to criminal activity. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" throw when bolted. Glass windows in the trailer should be shatter-resistant. I recommend the developer post appropriate "No Trespassing" signs on the property (in numerous locations) while it's under construction (appropriate verbiage flier attached). This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. The use of off-duty police officers or private security guards to patrol the site during the hours of darkness is highly recommended. The City should continue the security of this property following construction. COMPLETED BUILDING It's important to direct all foot traffic into the main entrance of the aquatic center. This should be monitored during all hours of business by placing a reception/ticket area in the front of the center, with participant access severely restricted.

The outside of these doors should be marked as "Alarmed Door" in red, at least 6 inches in height. Any payphones should be posted away from the changing rooms, and set up at out-going only. The fencing around the pools should be enhanced (for security purposes) with razor Page 1 of 2 PROJECT LUA 02-147, SA-H, ECF Aquatic Center City of Renton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET (Continuation) or barbed wire.

Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. 6. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per square foot of new commercial building area prior to the issuance of building permits. D. ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1. Earth Impacts: A geotechnical report prepared by Associated Earth Sciences, Inc. dated December 2002 was submitted with the project application. The report indicates the site slopes very gently (less than 5%) towards the Cedar River located about 700 to 800 feet to the southwest. The reports states that the subsurface conditions consist of 6-inches of sod and topsoil. Beyond the sod and topsoil, the alluvium consists of silty to clean sand and gravel. In general, the upper horizon of the alluvium was loose to medium dense silty sand. The project area is primarily undeveloped, with a cover of grass and scattered trees, which is currently utilized as a ball field and picnic area. Project excavation would include the installation of the new pools and the building foundations. Preliminary calculations for the project excavation, which may be situated up to eight feet below the existing grade, are approximately 2,800 cubic yards of cut material. Of the 2,800 cubic yards of cut material, approximately 600 cubic yards would be utilized as slope cut backfill. The remaining 2,200 cubic yards will be removed from the project site. In order to ensure potential erosion impacts don't occur during project construction, staff recommends the following mitigation measures: 1) temporary erosion control measures be maintained during project construction; 2) prior to any ercrpt.doc City of Renton P/B/PW Department Enviro, tal Review Committee Staff Report RENTON AQUATIC CENTER LUA-02-147, ECF, SA-H REPORT OF January 21,2002 Page 3 of 5 grading or clearing, install a silt fence along the down slope perimeter of the project area; 3) construct shallow drainage swales to intercept surface water flow and route the flow away from the construction area; 4) the contractor should conduct daily reviews and maintenance of the erosion and sedimentation control measures; 5) provide the Development Services Division with weekly reports on the status and condition of the erosion control plan. Staff anticipates that if these conditions are adhered to as well as existing code previsions, stormwater and erosion control would be adequately mitigated. Mitigation Measures: 1. Temporary erosion control measures shall be maintained to the satisfaction of the representative of the Development Services Division for the duration of the project's construction. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. Nexus: SEPA Environmental Regulations 2. Water—Stormwater/Groundwater Impacts: The applicant has submitted a Drainage Report prepared by Coughlin, Porter and Lundeen, dated December, 2002 with the land use application. The report indicates that the existing storm water collection system across the property is generally a catch basin and piped system. There are no existing detention storage facilities installed on the property. From the area of the new aquatic center, stormwater is piped approximately 1400 feet to an oil-water separator before traveling another 220 feet to a pipe end that discharges directly into the Cedar River. The stormwater analysis indicated that the use of the 1990 King County Surface Water Design Manual is appropriate in this instance. The report states that the water from the proposed pools would drain directly to the sanitary sewer system; therefore, the area of the pools has not been included in either the pre or post developed conditions. Based on those calculations, the report concludes that no additional detention or peak rate run-off control is required for this development. The applicant has proposed to convey stormwater collected from the proposed buildings and decks surrounding the pool via an underground conveyance system. The system would collect stormwater runoff from the pool decks via area drains, while the stormwater collected from the proposed buildings would be collected via downspouts piped to the conveyance system. This system would then tie into an existing catch basin located along the curb at the southwest corner of the site and follow the existing conveyance system, which eventually discharges into the Cedar River. As the applicant's drainage report and construction mitigation plan, as well as existing code provisions adequately mitigate stormwater concerns, staff does not anticipate the need for any additional stormwater mitigation measures. The proposed aquatic center is located within the Aquifer Protection Area Zone One (APA 1), the zone encompassing the City's aquifer recharge areas. In the APA 1 zone, code regulates the type and amount of hazardous materials that can be stored, handled, treated, used and produced on site. Specifically, within APA 1, the maximum amount of chemicals is limited to 500 gallons. In addition, secondary containment is required for all stored chemicals. Since chemical treatment is required for the general maintenance and operation of the aquatic center, the applicant would be required to adhere to the existing APA 1 regulations with regard to chemical usage and storage. ercrpt.doc City of Renton P/B/PW Department Environ al Review Committee Staff Report RENTON AQUATIC CENTER LUA-02-147, ECF, SA-H REPORT OF January 21,2002 Page 4 of 5 The applicant has indicated that the maximum amount of swimming pool chemicals kept on site at any one time would not exceed 200 gallons. In addition, the applicant has proposed to construct a secondary containment system, which would prevent any spills from reaching the ground water. As the existing code provisions adequately mitigate any concerns associated with ground water protection, staff does not recommend any additional mitigation measures. Mitigation Measures: No further mitigation is recommended. Nexus: N/A 3. Fire Protection Impacts: Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the condition that the applicant provide required improvements and fees. As the proposal would add approximately 6,500 square feet of additional building area, staff recommends that the applicant be required to pay a Fire Mitigation Fee in the amount of $0.52 per square foot of new building area. The total fee is estimated at $3,380.00 (6,500 square feet of new commercial buildings x $0.52.00 = $3,380.00). The payment of the fee is required prior to building permit issuance. Mitigation Measures: The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per new square foot of commercial building area prior to the issuance of the building permit. Policy Nexus: SEPA Environmental Regulations; Fire Mitigation Fee Resolution No. 2913, Ordinance 4527. 4. Transportation Impacts: Primary access to the site is proposed via Maple Valley Highway, while secondary access would be from Houser Way North. No new access points or streets are proposed as part of this project. Furthermore, as the site is an existing community park and the proposed project area is currently being utilized as a picnic area, soccer, baseball and football field (recreational), the proposed aquatic center use (recreational) would not trigger any additional traffic impact fees. The applicant has indicated that the aquatic center use would utilize the existing parking areas within the Cedar River Park, which are shared by the Community Center, ball fields and Carco Theater. Currently, there are approximately 400 parking stalls within the Cedar River Park. Staff has reviewed the parking areas and determined that the parking stalls meet current design standards regarding stall width, backout distance and drive aisle width. Therefore, staff recommends that no further traffic mitigation be required. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A E. COMMENTS OF REVIEWING DEPARTMENTS The proposal has been circulated to City Departmental / Divisional Reviewers for their review. Where applicable, these comments have been incorporated into the text of this report as Mitigation Measures and/or Notes to Applicant. _X Copies of all Review Comments are contained in the Official File.

There is a 12-inch water main in the entrance of the Community Recreation Center. Per the Fire Marshal, preliminary fire flow is 1750 gpm. No additional fire hydrants are required. Fire flow available (derated) is 3,650 gpm. Static Pressure is 60 psi. Pressure Zone is 196. SEWER There is an existing 8-inch sewer main under the footprint of the building. A sewer main relocation will be required. STORM There are stormwater facilities to collect the runoff from the project site. This project drains to the Cedar River STREETS Street improvements are installed along the frontage of the parcel and Maple Valley Road. CODE REQUIREMENTS WATER 1. Existing hydrants will be required to be retrofitted with Storz "quick disconnect" fittings. 2. New water meter(s) will be required. A reduced pressure backflow prevention device (RPBD) is required for the domestic meter. 3. Hazardous materials are limited to 500 gallons at one facility. Tetrachloroethylene (dry cleaning fluid) is banned in Aquifer Protection Zone 1. 4. Underground storage tanks containing hazardous materials are prohibited. 5. Annual operating permit is required for facilities if more than 20 gallons of liquid hazardous materials (200 pounds solid) are on premises. 6. Construction of secondary containment may be required if more than 200 gallons of regulated hazardous materials will be present at the new facility. 7. Impervious surfaces shah ue provided for areas subject to vE ular use or storage of chemicals. 8. See attached Memo from Carolyn Batsman, dated 01/09/03 SANITARY SEWER 1. A sewer main relocation may be required. 2. Both swimming pools are required to be connected to the sewer. The connection shall be either through the mechanical room or directly to the sewer. 3. Side sewer shall be a minimum 6-inch at 2% slope. SURFACE WATER 1. A drainage report per the 1990 KCSWDM has been submitted and reviewed. The project is under the threshold for detention and water quality. TRANSPORTATION 1. The Traffic Mitigation Fee of $75 per additional generated trip shall be assessed. According to the Environmental Checklist presented by the applicant, total daily trips would be 790 when pool is open. The transportation mitigation fee will be determined at a later date. PLAN REVIEW - GENERAL 1. All plans shall conform to the Renton Drafting Standards 2. Separate permits for side sewers, water meters and backflow device are required. When plans are complete three copies of the drawings, two copies of the drainage report, a construction estimate and application fee shall be submitted at the sixth floor counter. RECOMMENDED CONDITIONS 1. Due the proximity of the existing 12" water line to the excavation for the new pools, and to protect earth from cave-in around the water line and collapse of the water main during excavation for the new pools, staff recommends that a minimum 15-foot clearance be maintained between the water line and any structure. If the 15-foot clearance is not possible, shoring shall be provided to avoid disturbance to the existing water line. The water line shall not be undermined by construction activities. 2. Temporary Erosion Control shall be installed and maintained to the satisfaction of the representative of the Development Services Division for the duration of the project. 3. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in of the King County Surface Water Design Manual. This will be required during the construction of both off-site and on-site improvements as well as building construction. 4. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in KCSWDM. Temporary pipe systems can also be used to convey storm water across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 5. The project contractor snail perform daily review and maint€,,u,ice of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 6. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector. cc: Kayren Kittrick ( Y 0 ,, � ♦ � � 4.

Approval is requested to locate an Aquatic Recreation Center at the Renton Community Center. King County requires that a capacity charge be applied to any project that constructs a new connection to the sewer system, any reconnection within five years of a disconnection, or any change in use or building remodel that includes an increase in plumbing fixtures. King County generally receives notice of new construction; however, some sewer districts and/or the cities that represent them have neglected to report changes in use and tenant improvements that involve an increase in plumbing fixtures. In an attempt to remedy this problem, we are sending this reminder to you in response to the Public Re-Notice of Application. We ask that you forward this reminder to the sewer district or city department responsible for Sewer Use Certification forms: Please be sure that a Non-Residential Sewer Use Certification form for the above project is completed and sent to the King County Capacity Charge Program in a timely manner. The form should be sent to Eunice Verstegen, Capacity Charge Program, KSC-NR-0501, at the address above. If you need additional forms or have questions about the program, please call Eunice at (206) 684-1740. Thank you for the opportunity to review and comment on this proposal.

CITY OF RENTON FIRE PREVENTION BUREAU MEMORANDUM DATE: December 30, 2002 TO: Jason Jordan, Planner FROM: Jim Gray, Assistant Fire Marshal SUBJECT: Aquatic Center, 1715 Maple Valley ighway MITIGATION ITEMS; 1. A fire mitigation fee of $3,380.00 is required based on $.52 per square foot of the total building square footage. FIRE CODE REQUIREMENTS: 1. The preliminary fire flow is 1750 GPM, one hydrant is required within 150 feet of the structure and one additional hydrant is required within 300 feet of the structure. 2. Separate plans and permits are required for the installation of chemical water treatment systems. Please feel free to contact me if you have any questions. CITY OF RENTON MEMORANDUM DATE: June 20, 2002 TO: Project Team FROM: Jason E. Jord n, ssociate Planner SUBJECT: Swimming Pool Land Use Permit Timing In order to determine exactly what land use permits are required, Development Services strongly encourages Community Services to submit for a pre- application conference. A pre-application conference could be conducted in one to two weeks and can be initiated by submitting a conceptual site plan and accompanying project narrative. Based on our general knowledge of the project, Planning Staff has determined that the project would require environmental (SEPA) review, a Shoreline Substantial Development Permit and a Hearing Examiner Conditional Use permit. The land use permits would be processed concurrently. The process is expected to take a maximum of 16 weeks, from the time the application is accepted as complete, until the Hearing Examiner issues a decision and the appeal period(s) are complete. In this case, the City would have a project decision within 12 weeks from the date the application is accepted. Planning staff would attempt to run the shoreline permit and conditional use permit appeal periods concurrently, which may eliminate two to four weeks of processing time. In order to have all of the environmental and land use permits processed before the bidding process commences (on or about March 5, 2003), Community Services would need to submit for the land use permits in mid November, 2002. Building permits could be processed concurrently, but could not be issued until the completion of the appeal periods for the land use and shoreline permits. Please contact me at X7219 if I can be of further assistance.

The Aquatics Center will consist of a 9,520 square StevenJ.McNutt,AIA R.G.Nelson,AIA feet leisure pool, 3,837 square feet lap pool, and accompanying pool management and changing Benson A.Nielsen,AIA facility of 6,500 square feet. William M.Podobnik,AIA Richard A.Salogga,AIA The project schedule has going out to bid at the end of February, which would set proposed GregoryJ.Stack,AIA beginning of construction some time in April. The substantial completion date is set for December 191 , 2003. Thomas E.Golden,AIA Dana L.Harbaugh,AIA The Aquatic Center will operate approximately from Memorial Dayto Labor Da or later in Brent G Harding,AIA q p pp y y' Douglas G.Heyamoto,AIA September depending on the seasonal weather, The center is planned to be open every day, with Michael R.O'Malley,AIA possibly different daily hours of operation from workdays to weekends. The exact hours are GuyJ Overman,AIA operational issue, but usual hours of operation for facilities of this kind are as follows. The pool William W Rash,AIA Bruce B.Turner,PE opens between 5:30 to 6:00 a.m. for lap swimmers, which is followed by swimming lessons until about 9:00 or 10:0a.m. Some swimming lessons can be done in the wave pool during the lap pool use hours. General public admission starts usually at late morning hours between 10:00 and 12:00 and continues until 7:00 or 8:00 p.m. The surplus soil from the excavation will be hauled away by the only access to the site, which is from Maple Valley Highway in the immediate vicinity of the Aquatic Center location. From there hailing can continue by main traffic routes, which include immediate access to 1-405 northbound. Building of the proposed facility anticipates only standard construction methods. Dust and air disturbance will be limited to site work and immediate area around. Site work is limited to excavations, grading, paving and modification of landscaped areas. The contractor is anticipated to provide normal control measures for site work. During construction of the project temporary and permanent measures will be installed to minimize sediment laden runoff from discharge into the local waters. These measures include a stabilized construction entrance, interceptor swales, inlet protection and filter fabric fencing. For the period between November 1 through March 1 disturbed areas greater than 5,000 square feet left undisturbed for more than 12 hours must be covered with mulch, sodding, or plastic covering. Finally, all cleared areas will be revegetated after grading is completed. Anticipated hours for hauling soil are within normal construction working hours. Since major freeways are right next to the site no impact is anticipated to the surrounding area. There is no preliminary traffic control plan since the construction is anticipated to take place during the normal construction hours. Due to the relatively small size of the project and the fact that construction related trips will use only main traffic routes during regular working hours traffic impact will be negligible. Please advise if we need to provide more information on the subject. Thank you in advance.

Total area of the facility will cover 69,000 square feet. Richard A.Sologga,AIA Gregory J.Stack,AIA Required Land use permits for the project are Hearing Examiner Conditional Use permit and environmental (SEPA) review. The land use permits will be processed concurrently. Thomas E.Golden,AIA Dana L.Harbaugh,AIA The exact/proper pool site is a part of larger Cedar River Park, and is located at the Northeast Brent G.Harding,AIA corner of the current green fields area. Maple Valley Highway is to its northeast, with residences Douglas G.Heyamoto,AIA across the highway way up the hill. Cement plant is to site's southeast, and the park property is to Michael R.O'Malley,AIA Guy J.Overman,AIA the south, with Cedar River as the boundary about 570 feet away from the curb at the proposed William W.Rash,AIA pool site. Existing zoning designation of the site is COR1. Bruce B.Turner,PE The Cedar River Park is used for sports and recreation, primarily for baseball, softball and soccer, but also picnics and other individual activities. There are no known planned existing improvements, other than the proposed project. The Renton Aquatics Center will be a facility for recreational use, which will complement already existing uses in the park. The pool site is a completely flat site and will remain as such. There are no special site features such as wetlands or other water bodies. Cedar River is about 570 feet away from the curb at the proposed pool site, which is larger than 200 feet shoreline buffer. Site soils generally consist of about 8 to 10 feet of sand and silty sand mapped on the King County Soil Survey by the United States Department of Agriculture Soil Conservation Service (USDA SCS) as Pilchuck Loamy Fine Sand. Clean, free draining gravel underlies the sand below these depths. Enclosed Subsurface Exploration, Geological Hazard, and Preliminary Geotechnical Report prepared for Renton Aquatics Center Project for City of Renton, describes soil conditions in greater detail. As previously mentioned the Renton Aquatics Center will be a facility for primarily recreational use, with possibility for other related uses like swim lessons, therapeutic use of"lazy river" part of the leisure pool, occasional swim meets, etc. The site layout preserves adjacent roads and parking intact, with only necessary accessible and service ramp modifications to the existing road curbs. Therefore the scope of the project is limited to the existing property within the existing green fields area. The only access to the property is from the Maple Valley Highway to the north, at the existing traffic light. That will remain so until the separate project for Male Valley Highway improvements gets constructed, when the entry to the Cedar River Park and the aquatics center will move over 500 feet along the road to the east. That project is independent from proposed Aquatics Center. There are no proposed off-site improvements in the scope of the project. Calculations show that Offices in Seattle,Spokane existing fire hydrants are sufficient to adequately serve the new facility, and the utilities have and Coeur d'Alene capacity to absorb new use. 2201 Sixth Avenue Suite 1405 The estimated construction cost upon completion of design development phase is around $3.4 Seattle,Washington million. This type of the aquatic center has not been done in this area before, and it is hard to 98121-1832 estimate the fair market value of the new facility.

Preliminary calculations for the pool excavation that could be up to 8 feet below the existing grade are about 2,800 cubic yards of excavation with about 600 cubic yards being stockpiled and reused as slope cut backfill. The majority of on-site soils are suitable for use as structural fill. Approximately 2,200 cubic yards will be hauled from the site. The pool sub-drain system is not anticipated to have any effect on the underground water table. A pool sub-drain monitoring well will be installed to measure the level of groundwater underneath the pools. The groundwater level will need to be monitored when it would be time to empty the pools. If the groundwater level is high and the pools are emptied, there could be buoyancy forces acting on the pools that could actually cause the pools to 'pop'out of the ground. If the water table was high, the groundwater could be pumped down to avoid this potential problem. All pumping of the groundwater would be fully coordinated with the City of Renton. Trees to be removed are (9) 12" caliper Pin Oaks and (1) 3' caliper Big Leaf Maple, which is hollow inside. The Renton Aquatics Center will be a facility for recreational use, which will share parking areas provided for the whole complex, including the Community Center and the Theater. Given the lack of precise code requirements for parking for Community Center and Aquatic Center, and the real life experience regarding the use of these facilities, we have done analysis of the existing conditions and parking requirements for intended uses. Per conclusions of the analysis, we will request a modification based on our understanding of the parking requirements. Please see enclosed letter describing Justification for Parking Modification. Please advise if we need to provide more information on these topics. Thank you in advance.

Since the existing Development Regulations do not have precise code R G Nelson,AIA requirements for parking for Community Center and Aquatic Center, we have applied the most Benson A.Nielsen,AIA William M.Podobnik,AlA similar listed uses to determine what would be required number of parking stalls. The parking Richard A.Salogga,AIA chart is attached and listed as well on the overall site plan on drawing A-2. The Renton Aquatics GregoryJ.Stack,AIA Center will be a facility for recreational use, which will share parking areas provided for the whole complex, including the Community Center and the Theater. No existing parking spaces will be Thomas E.Golden,AIA removed by the proposed project. The new construction area is almost completely inside the Dana 1.Horbaugh,AIA existing road curbs. It is only grass and the existing picnic shelter that will be removed. Presented Brent G.Harding,AIA analysis of the existing conditions and intended use is the reason to ask for Justification for Douglas G.Heyamoto,AIA Modification. Michael R O'Malley,AIA Guy J.Overman,AIA William W.Rash,AIA It is our experience that most codes do not specifically mention leisure pools when calculating Bruce B.Turner,PE parking requirements. The same is the case with Development Regulations for Renton, Washington. We are often asked what our practical experience tells us to provide. Typically, and at the Renton Aquatic Center, we would expect up to half of the users to arrive on foot, via bicycle, skateboard, or via auto drop-off. This means that the other half will arrive by car and needs to park on site. Our experience suggests that the occupancy of cars averages 3.5 persons per car, since mothers are often bringing a group of children to the pool. These kinds of facilities are also very popular with children and younger teenagers who like to come in groups, but can not drive themselves. Younger teenagers very much like to spend time at the pool with their peers, and not necessarily with their parents being with them. These users need to be dropped off at the facility, and picked up later in the day. Our evaluation of parking available to the whole site shows that there are 400 total paved parking stalls available. The Maple Valley Highway road improvement project, currently under design, will provide 38 new parking stalls that will be used primarily for the pool, and offset loss of parking at the south road edge. Future plans consider relocating the existing maintenance facility located at the North-East corner of the park and converting it to parking, which could provide up to 77 new parking stalls, which would be used almost exclusively for the Aquatic Center. Potential parking improvement in the future could include arranging a parking agreement with the adjacent cement plant. The agreement would describe seasonal use of certain area for relief parking during times not required by the plant. It is not uncommon for pools and other civic or public facilities in the area to arrange agreements of this kind. It is a more efficient use of impervious surfaces and benefits the community at large. Also, the area between the Community Center and 1-405 is currently very much underutilized, and could easily receive parking enlargement for about 25 new stalls. In summary: Existing Spaces 400 Offices in Seattle,Spokane Future: Current Maintenance Facility Site converted to parking 77 and Coeur d'Alene Potential: Area Between 1-405 and Community Center 25 2201Sixth Avenue Suite 1405 Seattle,Washington Agreement with Cement Plant unknown 98121-1832 Total Potential Parking Spaces 502 TEL 206-441-4522 FAX 206-441-7917 nac©nwarchco.com www.nwarchco.com • City of Renton, Community Services—Planning Department December 18,2002 Page: 2 At present parking availability and facility occupancy of fewer than 1,000, it means that less than 150 parking stalls are needed to provide parking for 50% of the pool users, at factor of 3.5 people per car. If all future potential parking gets built, the pool will have about 100 new adjacent parking stalls available for its use. At a 3.5 factor this could provide for about 350 additional occupants arriving and parking their car. That means that if less than half of existing parking is occupied by the pool users, eventually 100% of pool occupants could have nearby pool specific parking stalls. However, the experience shows that such extent of parking availability is not needed on the regular basis. It is the occasional days when something extremely attractive is happening elsewhere in the park (old cars show, etc), which brings large number of individual visitors, that the additional parking will serve as a relief. The anticipated pool peak hours for parking are on weekends, and during the first two hours the pool is open for public use. The exact time is an operational issue, but it can be assumed that it will happen somewhere from 10-12 in the morning. The pool will typically be used by swim teams, aerobics, therapeutical use for seniors, etc. in the early morning hours. This is not the same as the anticipated peak hours for the Community Center, which are during Saturday afternoon. A wedding reception party of 300 would need to use 120 parking stalls at the conservative factor of 2.5 persons per car. That would leave about 280 current stalls for non-wedding uses. If 80 more spaces get used for other uses at the community center and the sport fields that would leave 200 stalls for afternoon pool use, which provides for 700 users using a 3.5 factor for all users. Theater peak hours are usually in the evening and are not assumed to overlap with the pool peak hours. From the explained analysis our design team has concluded that there is enough paved parking presently on site for regular pool operations. The potential future parking will just come in handy for the occasional days of special events at the park. Therefore we believe that modification is justified, since it complies with modification criteria. a) The existing parking that will be available for the Aquatic Center meets functional, appearance, safety, environmental protection, maintainability and overall Code requirements. b) The available parking is not injurious to other properties in the vicinity. c) Design and location of available parking conforms to the intent and purpose of the Code d) Presented analysis shows that the modification is justified and required for intended use. e) There are no properties in the vicinity that would be adversely impacted by this modification. Please advise if we need to provide more information on these topics. Thank you in advance.

Location of the proposal. Give sufficient information for a person 111EC ���` L.940 Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT to understand the precise location of your proposed project, including a street address, if any, and section, township and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographical map, if reasonable available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The site is located at the North-East corner of the field area of the Cedar River Park. It is bounded on the north by the Maple Valley Highway, the current entry/ service road for the Community Center to the east, existing parking to the south and soccer and baseball fields to the west. B ENVIRONMENTAL ELEMENTS 1 Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other. b. What is the steepest slope on the site (approximate percent slope)? Less than 2%. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat muck)? If you know the classification of agriculture soils, specify them and note any prime farmland. The Geotechnical Report describes the site soils as "Site soils generally consist of about 8 to 10 feet of sand and silty sand mapped on the King County Soil Survey by the United States Department of Agriculture Soil Conservation Service(USDA SCS) as Pilchuck Loamy Fine Sand. Clean, free-draining gravel underlies the sand below these depths. d. Are there surfaces indications or history of unstable soils in the immediate vicinity? If so, describe. The near-surface sandy soils are in a loose condition, and are subject to post- construction foundation settlement if foundations are placed directly on these soils without prior remediation.No other unstable soils were encountered. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Excavation will be performed for the installation of the new pools and building foundations. Preliminary calculations for the pool excavation that could be up to 8 feet below the existing grade are about 2,800 cubic yards of excavation with about 600 cubic yards being stockpiled and reused as slope cut backfill. The majority of on-site soils are suitable for use as structural fill. Approximately 2,200 cubic yards will be hauled from the site. f. Could erosion occur as a result of clearing, construction or use? If so, generally describe. No. Pools required excavations will require only standard construction pool walls support. The near-surface sandy soils will be moderately erosion-sensitive when exposed to surface water or high winds given their relatively small grain size and moisture sensitivity.Therefore,during clearing and grading operations,these soils will require erosion protection measures as discussed below. Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? 38%of the whole site. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any? Erosion control measures are as follow: 1) All storm water from impermeable surfaces should be tightlined into approved storm water drainage systems or temporary storage facilities. 2) To reduce the amount of soil transport,silt fences should be placed along the site perimeter. 3) Construction should proceed during the drier periods of the year if possible and disturbed areas should be revegetated as soon as possible. 4) Soils to be reused around the site should be stored in such manner as to reduce erosion. Protective measures may include,but are not necessarily limited to, covering with plastic sheeting, or the use of straw bales/silt fences. 2. Air a. What types of emissions to the air would result from the proposal (i.e. dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. A small amount of dust from construction mainly during the summer months in 2003 and exhaust from contractor vehicles and equipment b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No c. Proposed measures to reduce or control emissions or other impacts to air, if any: Normal construction dust control measures for site work. 3. Water a. Surface 1. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal steams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. No. Cedar River is about 570 feet away from the closest road curb, which is greater than the 200 feet shoreline buffer required. 2. Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. No 3. Estimate the amount of fill and dredge material that would li Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material N/A 4. Will the proposal require surface water withdrawals or diversions? Give the general description, purpose, and approximate quantities if known. No 5. Does the proposal lie within a 100 year floodplain? If so, note location on the site plan. No. 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground 1. Will ground water be withdrawn or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No 2. Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agriculture; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. N/A c. Water Runoff(including storm water): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. Rainfall will be collected in on site storm system and conveyed to existing city storm system. 2. Could waste materials enter ground or surface waters? If so, generally describe. Water treatment chemicals for pool maintenance will be stored on site but will meet all the requirements of an Aquifer Protection Area (Zone 1). There also are no new pollution generated surfaces proposed for the site. Therefore,negligible waste materials will enter ground or surface waters. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: The proposed development will have little new impervious area,and as such the increase in surface runoff will be negligent. Water from the swimming pools will be directed to the sanitary sewer system. Surface water runoff will be discharged in the natural pre-developed location,and will have Environmental Checklist (Continued) TO BE COMPLETED BY APPLICANT insignificant impact on the downstream system. 4.

CC: Kayren Kittrick 1 ' I it CITY OF RENTON Planning/Building/Public Works MEMORANDUM DATE: November 14, 2002 TO: Pre-Application File No. 02-095 i FROM: Jason E. Jordan, Associate Planner, x7219 1 SUBJECT: Renton Aquatic Center 1 General: We have completed a preliminary review of the pre-application for the above-referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on i the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Zoning 1 Administrator, Board of Adjustment, Board of Public Works, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or 1 made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available for purchase for $50, plus tax, from the Finance Division on the first floor of City Hall. Project Proposal: The subject site is located at the Cedar River Park, between Interstate 405 and the Maple Valley Highway. The property is currently developed as a community park with a community center and theater. The Cedar River is located directly south of the park site. The project proposal is to construct two separate swimming pools, which would consist of a 25-yard, 6-lane lap pool and a 9,000 square foot leisure pool. The leisure pool would consist of a wave pool area, a quite pool play area and a lazy river with water slides. Zoning: The subject site is designated Center Office Residential (COR) on the City's Zoning and Comprehensive Plan Map. The purpose of the Center Office Residential land use designation is to provide for a mix of intensive office, hotel and convention center and residential activities in a high- quality, master planned development,that is integrated with the natural environment. Development Standards: The proposal would need to comply with the COR zone development standards and other associated regulations as addressed below: ea Lot Coverage - The COR zone allows building coverage at a maximum of 65% of the lot area for y projects not providing structured parking, or 75% if parking is provided within the building. The proposed aquatic center is not expected to increase lot coverage within the existing development beyond what the development standards allow. Setbacks — Setbacks are measured from the property lines to the nearest point of the structure. The .l required setbacks in the COR zone are determined through the site plan review process. In this II :yolticase, staff generally supports the proposed aquatic center location; however, the formal site plan j ° review submittal would need to be more detailed in order to provide exact setback measurements. i Freeway Frontage Setback: -The minimum freeway frontage setback (along Interstate 405 and Maple eip • Valley Highway) is 10 feet of landscaped area. 7 N1J � Height — The COR zone permits a maximum building height of 10 stories and/or 125 feet. The information provided did not indicate the proposed building height. Building height is measured from the mid-point of a pitched roof to the average finished grade and must be clearly indicated in the plans n submitted for the building permit application. 1 Screening—Outdoor storage is not permitted in the COR zone. Outdoor loading, repair, maintenance or work areas, if any, must be screened from adjacent or abutting residential properties with a fence, • Renton Aquatic Center Pre-Applicatio.. ,., eting File No.Pre-02-095 November 14,2002 Page 2 of 2 landscaping, landscaped berm, or combination thereof. All surface-mounted utility or mechanical equipment and rooftop equipment must be screened from public view. The provision of adequate screening will be carefully considered during the building permit review process, especially with regard to potential noise impacts from the drive through proposed to the rear of the building immediately adjacent to the residentially zoned property. Dumpsters — Screening must also be provided for all garbage dumpsters and recyclable areas pursuant to RMC section 4-4-09007. Dumpsters are not permitted within required setback areas, as well as within 50 feet of a residentially zoned property. In addition, approval of the proposed locations of dumpster areas by Rainier Waste Management is recommended prior to the submittal of the formal land use application. The building permit application (j will need to include elevations and details on the proposed methods of screening. Pedestrian Access — A pedestrian connection is required to be provided from the public entrances of the aquatic center to the street frontages and parking areas. The information submitted did not include how pedestrian access would be provided. Parking/Circulation — The parking regulations require a specific number of spaces based on the at) amount of square footage dedicated to certain uses. In this case, all the uses on the site would be reviewed as part of the site plan review process. The existing community center and the proposed aquatic center would be required to provide parking at a ratio of 1 parking stall per 50% of the maximum occupancy load as established by the Building Code. The theater is required to provide 1 parking stall per every 4 fixed seats or 1 for each 100 square feet of auditorium area. A required parking and provided parking analysis would need to be submitted with the formal site plan review application. In the event, the subject site is under parked, an administrative parking modification would be required. Signage: Only one freestanding business sign (pole, monument/ground, projecting or roof) is permitted per street frontage for each individual parcel. Each sign shall not exceed an area greater than one and one-half square feet for each lineal foot of property frontage that is occupied by the business. In no case shall the sign exceed a total of 300 square feet(150 square feet per face if a two face sign). Pole signs are limited to the maximum height specified in the zone, or a maximum of 40 feet, whichever is less and must comply with the setback requirements of the zone. In addition to the permitted freestanding sign, wall signs with a copy area not exceeding 20% of the facade to which it is applied is also permitted. Environmental Issues: While the proposed aquatic center is located near the Cedar River, it appears all construction would be located beyond 200 feet of the Cedar River Ordinary High Water Mark (OHWM). Therefore, the project would not require a shoreline substantial development permit. No other environmentally sensitive areas were identified within the project site. Permit Requirements: The proposal would require Environmental (SEPA) Review and City Council Site Plan Approval. It should be noted that as the project is located in a COR zone, City staff would make a recommendation to the City's Hearing Examiner,who would then make a final recommendation to the City Council. The City Council would issue the final approval for the project. The review process would be completed in an estimated time frame of 12 to 16 weeks once a complete application is accepted and assuming no appeals are filed. The application fee would be $2,500.00, plus $0.37 per mailing label required for notification to all property owners within 300 feet of the site. In addition to the required land use permits, separate construction, building, and sign permits would be required. The review of these permits may occur concurrently with the review of the land use permits, but can not be issued prior to the completion of any required appeal periods. cc: Jennifer Henning Pre02-095(aquatic center in cor zone with site plan review).doc\ CITY OF RENTON ECONOMIC DEVELOPMENT NEIGHBORHOODS, AND STRATEGIC PLANNING MEMORANDUM DATE: November 7,2002 DEVELOPMENT PLANNING CITY OF RENTON TO: Jason Jordan OV S .1,2 Aw FROM: Rebec6 Lind RECEIVED STAFF CONTACT: Don Erickson SUBJECT: Cedar River Park Aquatics Center, PRE 02-095 • The applicant, the City of Renton Community Services Department, is proposing the development of an aquatic center in Cedar River Park. The proposed facility would be located northeast of the existing Community Center building near Maple Valley Highway at the north end of the existing main parking lot. The proposed new facility has been sited over a portion of the existing access road from Maple Valley Highway making it unclear how future ingress and egress between the Maple Valley Highway and the park will be provided. The subject site is designated Center Office Residential on the Comprehensive Plan Land Use Map and is zoned COR. Comprehensive Plan policies are listed below. Relevant Comprehensive Plan Land Use Policies: Policy L U-130. A public review process should be required for proposed development plans of each parcel with separate ownership or abutting parcels of the same ownership within the Center. Policy LU-132. Site plans and proposed structures should be designed so as to fully integrate signage, building height, bulk setbacks, landscaping, and parking considerations across the various components of each proposed development. � > Policy LU-133. Internal site circulation should be primarily pedestrian oriented. Objective LU-HH: Site and design municipal facilities to provide the most efficient and convenient service for people while minimizing the adverse impacts on surrounding uses. Policy LU-243. Siting of regional facilities which are specialized or serve a limited segment of the population should rely more strongly on the special locational needs of the facility and the compatibility of the facility with surrounding uses. Policy LU0346. The park system should include neighborhood, community, and regional parks with sufficient acreage and facilities to meet standards adopted by the Renton Parks Commission. • Cedar River Park Aquatics Center 2 11/07/02 Policy LU-351. Existing parks should be more intensely developed to provide needed recreation facilities where feasible. Analysis: The proposed new Aquatic Center appears to comply with most of the above land use policies. It will be important to ensure that its design and siting are compatible with other municipal facilities such as the Community Center and Carco Theater already in Cedar River Park (Policy LU-243). Consideration should also be given to creating a clearly delineated pedestrian walkway between the new center and the existing Community Center complex to the southwest (Policy LU-133). The proposed intensification of uses within the Cedar River Park would also appear to be consistent with Policy LU-351. Recommendation: • Support the current proposal while seeking additional clarification on how and where future ingress and egress from Maple Valley Highway will be provided as well as what provisions are being made for pedestrian-oriented circulation between the new Aquatics Center and the Community Center complex to the southwest. cc: Don Erickson H:\EDNSP\Interdepartmental\Development Review\Preapps\Comments\PREAPP\COR\City Aquatics Center.doc\d 704, MEMORANDUM DATE: I I /4-10z TO: Construction Services, Fire Prevention, Plan Review, EDNSP, Project Planner FROM: Neil Watts, Development Services Division Director SUBJECT: New Preliminary Application: A f Mcc (/61-16,- LOCATION: Cpa1.41,r ,e'-wpv )Ght) PREAPP NO. 02 — 0975- A meeting with the applicant has been scheduled for // • , Thursday, Mdi/.

The design for the Renton Aquatic Center is based on the requirements set forth in the 1990 King County Surface Water Design Manual (KCSWDM). The Renton Aquatic Center,located near the intersection of SE Maple Valley Highway(SR 169)and Bronson Way N in Renton,WA(see Figure 1)and is located in an incorporated area on the King County Flow Control Applications Map. The approximately 1.6-acre site is in the Cedar Main Urban Basin plan. The project site slopes very gently towards the Cedar River located about 700 to feet to the southwest. The site was last developed in the late 1980's prior to any County code requirements that addressed the detention of storm water for flow control. The City of Renton is constructing a new Aquatic Center on the 20-acre Renton Community Center property in an area that is primarily undeveloped with lawn and scattered trees. The development would include a six-lane lap pool,several activity pools,a picnic area and building to support changing rooms,restrooms, concessions,and mechanical equipment. The majority of the site area(approximately 250 feet by 310 feet) will be either hard-surfaced or landscaped with grass. Existing Drainage System This entire Renton Community Center property is approximately 20-acres and is developed with impervious areas including buildings,parking lots,and sidewalks. The remainder of the site is predominantly landscaped areas including grass playfields. The existing storm water collection system across the property is generally a catch basin and piped system. There is no existing detention storage facilities installed on the property. From the area of the new Aquatic Center,stormwater is piped approximately 1400 feet to an oil- water separator before traveling another 220 feet to a pipe end that discharges directly into the Cedar River. Proposed Drainage System Stormwater improvement requirements for the site fall within the incorporated area of the City of Renton and the 1990 King County Surface Water Design Manual(KCSWDM). To determine if detention is required for the new development,calculations were performed using the Santa Barbara Unit Hydrograph(SBUH) method. It should be noted that since the water from the proposed pools drains directly to the sanitary sewer system,the area of run-off for the pools have not be included in either the pre or post developed conditions which results in a more conservative analysis. The pools will maintain a water level at least four inches below the surrounding deck surface to prevent any spillover during a significant rainfall event. Modeling both the existing and proposed conditions for the 100-year,24-hour storm event,there is a net increase of discharge from the site of 0.39 cfs(0.89 cfs post-dev-0.50 cfs pre-dev)after development. The project falls under the exemption from on-site peak rate runoff control(1990 KCSWDM#1.2.3)that states if: "The proposed project site post-development peak run-off rate for the 100-year,24-hour duration design storm event is calculated for each discharge location to be less than 0.5 cfs more than the peak runoff rate for the existing conditions" Therefore,no detention or peak rate run-off control is required for the new development. COUGHLINPORTERLUNDEEN Renton Aquatic Center 1 To convey stormwater from the site,a conveyance system will be installed including several area drains connected by piping. Building roof downspouts will be piped directly to the new conveyance piping. This system will then tie into an existing catch basin located along the curb at the southwest corner of the site and follow the existing conveyance system eventually discharging to the Cedar River. There will be no new pollution generating surfaces including such items as metal roofing and asphalt/concrete paving areas for the site,therefore water quality improvements will not be required. There will be some chemicals for the treatment of pool water that will be stored on the site in chemical storage that will meet with all the requirements of the Aquifer Protection Area(Zone 1)requirements including a limit of 500 gallons of materials and a containment dike surrounding the covered storage areas. Temporary Erosion and Sediment Control During construction of the project temporary and permanent measures will be installed to minimize sediment laden runoff from discharge into the local waters. This measures include a stabilized construction entrance,interceptor swales,inlet protection and filter fabric fencing. For the period between November 1 through March 1 disturbed areas greater than 5,000 square feet left undisturbed for more than 12 hours must be covered with mulch,sodding,or plastic covering. Finally,all cleared areas will be revegetated after grading is completed. Summary Stormwater improvements include a new conveyance system with roof downspouts that will connect to the existing on-site system. Per the 1990 KCSWDM exception#1.2.3,no additional detention will be required for the project because there is a less than 0.5 cfs increase in the runoff rate for the 100-year,24-hour storm event between existing and proposed conditions. Also,since there are no new pollutions generating surfaces, stormwater quality control improvements are not required. COUGHLINPORTERLUNDEEN Renton Aquatic Center 2 II. CONDITIONS AND REQUIREMENTS SUMMARY This section addresses the requirements set forth by the Core and Special Requirements listed in Chapter 1 of the 1990 KCSWDM. King County Surface Water Management Design Manual Core Requirements: 1. Discharge at a natural location(1.2.1): All developed flows will be discharged at their natural locations. 2. Off-site Analysis(1.2.2): A preliminary Level 1 downstream analysis has been performed. 3. Runoff Control(1.2.3): A. Peak Rate Runoff Control:Modeling both the existing and proposed conditions for the 100-year,24- hour storm event,there is a net increase of discharge from the site of 0.39 cfs(0.89 cfs post-dev-0.50 cfs pre-dev)after development. The project falls under the exemption from on-site peak rate runoff control that states if 'the proposed project site post-development peak run-off rate for the 100-year,24-hour duration design storm event is calculated for each discharge location to be less than 0.5 cfs more than the peak runoff rate for the existing conditions.' Therefore,no detention or peak rate run-off control is required for the new development B. Biofiltration:Basic water quality is not required for this site. No new pollution generated surfaces will be added. 4. Conveyance System(1.2.4): Existing conveyance facilities will remain. This proposed project will incorporate an on-site conveyance system that will connect downstream into the existing storm system. The increase in discharge flows is insignificant and will not affect the downstream conveyance system. The proposed conveyance system will be sized to convey up to the 25 year storm event. 5. Temporary Erosion and Sedimentation Control(1.2.5): The project is installing sediment control measures as required to address the specific conditions at the site. COUGHLINPORTERLUNDEEN Renton Aquatic Center 3 King County Surface Water Management Design Manual Special Requirements: 1. Critical Drainage Areas(1.3.1): This project is located in the Cedar River Drainage Basin and will comply with any requirements the basin plan may impose. 2. Compliance with an Existing Master Drainage Plan(1.3.2): The project does not require a master drainage plan. 3. Conditions requiring a Master Drainage Plan (1.3.3): The project does not require a master drainage plan. 4. Adopted Basin or Community Plans(1.3.4): The project does not lie within an area with an adopted Basin or Community Plan 5. Special Water Quality Controls(1.3.5): The proposed project will not contain more than one acre of impervious surface that will be subject to vehicular use or storage of chemicals and does not require water quality control. Project Specific Requirements: This site does not abut a Class 1 or Class 2 stream that has an existing flood protection facility and is exempt from this requirement.This site is not required to provide any additional source control. COUGHLINPORTERLUNDEEN Renton Aquatic Center 4 III.OFF-Sl'1'h ANALYSIS Task 1— Study Area Definition and Maps As-built plans for the Renton Community Recreation Center dated August 1989 were reviewed for an evaluation of the existing conveyance and drainage systems. Task 2-Resource Review a) Basin Reconnaissance Summary Reports: The reports did not indicate arty conveyance problems. b) Critical Drainage Area Maps: The site is not within Critical Drainage Area c) Floodplain/floodway(FEMA)Maps: Site is not within a FEMA designated area,see Figure 3 d) King County Soils Survey: Soils map,see Figure 4 e) Wetland Inventory Maps: See Sensitive Areas Maps,Figure 3 f) Sensitive Areas Folio: Site is not within any sensitive areas,see Figure 3 Task 3-Field Inspection One site visit has been made to the site to gather information to be used in the Level 1 Downstream Analysis and off-site conveyance system inspection. Task 4-Drainage System Description and Problem Descriptions We did not observe any off-site conditions or problems that would affect or that would be affected by the on- site storm drainage system. Upstream Analysis The site does not have any off-site areas contributing directly to on-site runoff. There are permanent drainage systems located in Maple Valley Highway(SR 169)and the private access drive southeast of the site that intercept and route drainage around the site. Downstream Analysis The existing stormwater collection system throughout the Renton Community Recreation Center is generally a catch basin and piped system. There is no existing detention storage facilities installed on the property. From the area of the new Aquatic Center,the proposed storm water conveyance system connects to an existing curb line catch basin southwest of the new site. From the new connection point through the existing system,the storm water travels 30 feet southeast in a existing 12-inch line before traveling approximately 360 feet west in series of 12-inch lines. The system travels approximately 210 feet north in a series of 12" lines before traveling about 400 feet west in a series of 15-inch pipes. The storm water then travels 350 feet southwest in a 15-inch pipe series before reaching a gravity oil/water separator housed in a 72-inch manhole with baffles. From the oil/water separator the storm water travels 250 more feet southwest before discharging directly into the Cedar River. The pipe outlet into the river is a 12-inch line with a flapper valve. The pipe end penetrates a stone wall with the pipe invert approximately 12 feet below the top of wall. COUGHLINPORTERLUNDEEN Renton Aquatic Center 5 Task 5-Mitigation of Existing or Potential Problems There are no existing flooding or erosion problems presently on the Renton Community Center property. The new Renton Aquatic Center results in an insignificant addition of impervious area to the overall property. Therefore,there will not be any potential flooding or erosion problems created by the project. COUGHLINPORTERLUNDEEN .

PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration, geologic hazard, and preliminary geotechnical engineering study for the proposed Renton Aquatic Center. The proposed facility will be located near the existing City of Renton Community Center southeast of the intersection of SR-169 and I-405, in Renton Washington as shown on the Vicinity Map, Figure 1. Our recommendations are preliminary in that site grading information and construction details have not been finalized at the time of this report. The approximate locations of the explorations accomplished for this study are presented on the Site and Exploration Plan, Figure 2. The site features shown on Figure 2 are based on a site plan provided by Coughlin Porter Lundeen (CPL). In the event that any changes in the nature, design, or location of the structures is planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. 1.1 Purpose and Scope The purpose of this study was to provide subsurface data to be utilized in the preliminary design and development of the above-referenced project. Our study included a review of available literature, excavation of exploration borings, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments, and ground water conditions. Geologic hazard evaluations and engineering studies were also conducted to determine suitable geologic hazard mitigation techniques, the type of suitable foundation, allowable bearing pressures, anticipated settlements, basement/retaining wall lateral pressures, floor support recommendations, and drainage considerations. This report summarizes our current fieldwork and offers development recommendations based on our present understanding of the 11'1 1.2 Authorization Written authorization to proceed with this study was granted by the City of Renton on November 7, 2002. Our study was accomplished in general accordance with our scope of work letter dated October 25, 2002. This report has been prepared for the exclusive use of the City of Renton and their agents, for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, express or implied, is made. Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner.

SGB/W-KE02672A3-Projects12002672IKEIWP-W2K Page 1 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Project and Site Conditions 2.0 PROJECT AND SITE DESCRIPTION This report was completed with an understanding of the project based on a site plan provided by CPL dated October 2, 2002, a site reconnaissance, and our familiarity with previous geotechnical work performed in the site area. We completed a subsurface exploration program consisting of two exploration borings on November 11, 2002. We understand the City of Renton intends upon constructing a new aquatic center adjacent to the existing community center. The area proposed for construction would measure some 350 feet by 250 feet in plan dimension. The development would include a six-lane lap pool, a kiddy pool, water slides, wave pool, and picnic area, as well as buildings to support changing rooms, restrooms, concessions, and mechanical equipment. The majority of the area would be hard-surfaced or landscaped with grass. The project area is primarily undeveloped, with a cover of grass and scattered trees. A covered picnic area and restroom facility is located on the northeast portion of the proposed development area. The site slopes very gently towards the Cedar River located about 700 to 800 feet to the southwest. The property is surrounded by light commercial properties. Site access is from SR-169, also know as the Maple Valley Highway. 3.0 SUBSURFACE EXPLORATION Associated Earth Sciences, Inc. (AESI) performed a subsurface exploration of the site on November 11, 2002. Our field study included advancing five exploration borings to gain subsurface information about the site. A ground water monitoring well (piezometer) was installed in one of the borings to record future ground water measurements. The various types of soils, as well as the depths where characteristics of the soils changed, are indicated on the exploration logs presented in the Appendix. The depths indicated on the logs where conditions changed represent gradational variations between soil types in the field. Our explorations were approximately located in the field by measuring from known site features and are shown on Figure 2. The conclusions and recommendations presented in this report are based, in part, on the five exploration borings completed for this study. The number, location, and depth of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions between field explorations is necessary. It should be noted that differing subsurface conditions may be present due to the random nature of deposition and the alteration of topography by past grading and/or filling. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific recommendations in this report and make appropriate changes. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGBab-KE0267 I3-Projects12002672IKEIWP-W2K Page 2 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Project and Site Conditions 3.1 Exploration Borings Exploration borings were advanced with a Mobile B53 track-mounted drill rig. The borings permitted limited visual observation of subsurface conditions. Representative samples of the soils encountered were obtained from the borings using a Standard Penetration Test (SPT) sampler. The SPT sampler obtains disturbed samples and was driven into the soil using a 140- pound hammer free-falling 30 inches. The number of blows required to drive the sampler the last 12 inches is recorded on the boring logs. Materials encountered in the exploration borings were studied and classified in the field by a geotechnical engineer from our firm. All exploration borings were sealed with bentonite and cement immediately after examination and logging. Selected samples were then transported to our laboratory for further visual classification and testing, as necessary. The boring logs have been attached to this report as an Appendix. 4.0 SUBSURFACE CONDITIONS Subsurface conditions at the project site were inferred from the field explorations completed for this study, visual reconnaissance of the site, and review of applicable geologic literature. As shown on the field logs, the exploration borings generally encountered up to 6 inches of sod and topsoil, overlying natural deposits of Quaternary alluvium. The alluvium consists of silty to clean sand and gravel. In general, the upper horizon of the alluvium was loose to medium dense silty sand. With depth, the alluvium graded to medium dense to dense, clean sandy gravel. The top of the dense alluvium varied from 1 foot in EB-1 and EB-4 to about 10 feet in the other borings. This bearing depth is shown in parentheses on Figure 2. The soil conditions encountered in our explorations are consistent with the published geologic mapping of the area. In particular, we reviewed the Geologic Map of Renton Quadrangle. King County, Washington, prepared by D.R. Mullineaux, 1965. This publication shows the project site underlain by Quaternary alluvium consisting of fine-grained floodplain deposits over coarser-grained river channel deposits. 4.1 Hydrology We did not encounter ground water in any exploration borings at the time of our study. However, very moist and oxidized soil occurred below 10 feet in EB-4 and EB-5. Given the site's close proximity to the Cedar River and the relatively dry climatic conditions in the Puget Sound Region over the past year, we elected to install a piezometer in EB-5, although ground water was not encountered within the upper 20 feet of the ground surface. Ground water at PP this site represents unconfined aquifer conditions common to alluvial plain deposits. Ground water elevations may rise significantly following extended periods of wet weather. We will monitor the piezometer occasionally over the upcoming winter months to evaluate ground water level fluctuations. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC.

GEOLOGIC HAZARDS AND MITIGATIONS The following discussion of potential geologic hazards is based on the geologic conditions as observed and discussed herein. 5.0 SLOPE STABILITY HAZARDS AND RECOMMENDED MITIGATION There are no steep slopes within the immediate project vicinity. Consequently, the risk of earth movement on the subject property is low due to the site's relatively flat topography. 6.0 SEISMIC HAZARDS AND RECOMMENDED MITIGATION Earthquakes occur in the Puget Sound Lowland with great regularity. The vast majority of these events are small and are usually not felt by people. However, large earthquakes do occur as evidenced by the most recent 6.8-magnitude event on February 28, 2001 near Olympia Washington, the 1965, 6.5-magnitude event, and the 1949, 7.2-magnitude event. The 1949 earthquake appears to have been the largest in this area during recorded history. Evaluation of return rates indicates that an earthquake of the magnitude between 5.5 and 6.0 is likely within a given 20-year period. Generally, there are four types of potential geologic hazards associated with large seismic events: 1) surficial ground rupture; 2) seismically induced landslides; 3) liquefaction; and 4) ground motion. The potential for each of these hazards to adversely impact the proposed project is discussed below. 6.1 Surficial Ground Rupture The nearest known fault trace to the project site is the Seattle Fault. Recent studies by the U.S. Geological Survey (e.g., Johnson et al., 1994, Origin and Evolution of the Seattle Fault and Seattle Basin, Washington, Geology, v. 22, pp. 71-74; and Johnson et al., 1999, Active Tectonics of the Seattle Fault and Central Puget Sound Washington — Implications for Earthquake Hazards, Geological Society of America Bulletin, July 1999, v. 111, n. 7, pp. 1042-1053) have provided evidence of surficial ground rupture along a northern splay of the Seattle Fault. The recognition of this fault splay is relatively new and data pertaining to it are limited with the studies still ongoing. According to the U.S. Geological Survey studies, the latest movement of this fault was about 1,100 years ago when about 20 feet of surficial displacement took place. This displacement can presently be seen in the form of raised, wave- cut beach terraces along Alki Point in West Seattle and Restoration Point at the south end of Bainbridge Island. The recurrence interval of movement along these fault systems is still unknown, although it is hypothesized to be in excess of several thousand years. Due to the December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/!b-KE02672A3-Projects12002 6 72 1KEIWP-W2K Page 4 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Geologic Hazards and Mitigations suspected long recurrence interval, the potential for surficial ground rupture is considered to be low during the expected life of the proposed structure. 6.2 Seismically Induced Landslides There are no steep slopes within the immediate project vicinity. Consequently, the risk of seismically induced landsliding on the subject property is low due to the site's relatively flat topography. 6.3 Liquefaction Under the present ground water conditions, the encountered stratigraphy has a low potential for liquefaction due to the dense condition of the gravel and the depth to ground water exceeding 20 feet. However, following extended periods of extremely high precipitation, ground water could rise to within 10 or 15 feet of the ground surface, or even higher during flooding events. The risk of liquefaction would increase if foundations were to be placed on the loose upper sandy alluvium. The risk to the structures could be mitigated by founding them on the lower dense gravel or replacing the upper loose material with compacted structural fill, or rock beneath the footings. Short aggregate pier foundations would also mitigate the liquefaction risk. 6.4 Ground Motion The project site is located within a Zone 3 rating for seismic activity on a scale of 1 (lowest) to 4 (highest) based on the Seismic Zone Map of the United States, Figure No. 16-2 in the 1997 edition of the Uniform Building Code (UBC). This zonation is based on past earthquake activity in the Puget Sound region. As such, design recommendations in the report accommodate the possible effect of seismic activity in areas with a Zone 3 rating, corresponding to a peak ground acceleration of 0.3g (a Richter magnitude 7.5 earthquake occurring directly beneath the site), in accordance with UBC guidelines, using soil type SD. 7.0 EROSION HAZARDS AND MITIGATION To mitigate and reduce the erosion hazard potential and off-site soil transport, we recommend the following: 1) All storm water from impermeable surfaces should be tightlined into an approved storm water drainage system or temporary storage facilities. 2) To reduce the amount of soil transport, silt fences should be placed along the site margins.

SGB/!b-KE02672A3-Projects12002672IKEl WP-W2K Page 5 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Geologic Hazards and Mitigations 3) Construction should proceed during the drier periods of the year and disturbed areas should be revegetated as soon as possible. 4) Soils to be reused around the site should be stored in such manner as to reduce erosion. Protective measures may include, but are not necessarily limited to, covering with plastic sheeting, or the use of straw bales/silt fences. 411 4' December 2, 2002 ASSOCIATED EARTH SCIENCES, INC.

PRELIMINARY DESIGN RECOMMENDATIONS 8.0 INTRODUCTION Our exploration indicates that from a geotechnical standpoint, the parcel is suitable for the proposed development provided the risks discussed are accepted and the recommendations contained herein are properly followed. We anticipate that construction of the pools will require excavation to depths of about 8 to 10 feet. The bearing stratum of medium dense to dense alluvium occurs at depths ranging from 8 to 10 feet within the proposed changing room building area, and depths ranging from 1 to 10 feet within the currently proposed pool areas. Therefore, it may be beneficial to consider relocating the proposed structures such that the pools are located within the areas of deeper bearing soils, and the buildings are located near the southeast site corner where shallow bearing soils occur. Limited removal and replacement of the loose surficial deposits is recommended for conventional foundation support. Alternately, short aggregate pier foundations could be used for support of the building using a higher allowable bearing pressure. 9.0 SITE PREPARATION Site preparation of planned building, pool, and other improvement areas should include removal of all trees, and any other deleterious material. Following demolition of the existing covered picnic area, any remaining foundation elements should be removed. Any buried utilities should be removed or relocated if they are under building or pool construction areas. The resulting depressions should be backfilled with structural fill as discussed under the Structural Fill section of this report. Additionally, the upper sod and organic topsoil should be removed and the remaining roots grubbed. Areas where loose surficial soils exist due to grubbing operations should be considered as fill to the depth of disturbance and treated as subsequently recommended for structural fill placement. In the explorations completed for this study, the bearing stratum of medium dense to dense alluvium occurs at depths ranging from 8 to 10 feet within the proposed building area, and depths ranging from 1 to 10 feet within the currently proposed pool areas. Since the density of the soil at the site is highly variable, random soft pockets may exist at the indicated bearing depth. Therefore, the depth and extent of stripping can best be determined in the field by the geotechnical engineer. Where possible, building, sidewalk areas, and pool excavation subgrades should be proof- rolled with a loaded, tandem-axle dump truck to identify any soft spots; soft areas should be overexcavated and backfilled with structural fill. If proof-rolling is not possible within the construction space or construction is to proceed during wet weather, we recommend systematic probing in place of proof-rolling to identify soft areas of the exposed subgrade.

SGB/!b-KE02672A3-Projects120026721KEIWP-W2K Page 7 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations In our opinion, stable construction slopes should be the responsibility of the contractor and should be determined during construction. For estimating purposes, however, we anticipate that temporary, unsupported cut slopes in the loose to medium dense sand and gravel alluvium can be made at a maximum slope of 2H:1V(Horizontal:Vertical). As is typical with earthwork operations, some sloughing and raveling may occur and cut slopes may have to be adjusted in the field. In addition, WISHA/OSHA regulations should be followed at all times. 10.0 STRUCTURAL FILL All references to structural fill in this report refer to subgrade preparation, fill type, and placement and compaction of materials as discussed in this section. If a percentage of compaction is specified under another section of this report, the value given in that section should be used. Construction plans are preliminary at this stage and do not include site grading information. However, placement of structural fill may be necessary in order to achieve the desired site grades. After stripping, planning excavation, and any required overexcavation has been performed to the satisfaction of the geotechnical engineer, the upper 12 inches of exposed ground in building areas or areas to receive fill should be recompacted to 90 percent of the modified Proctor maximum density using ASTM:D-1557 as the standard. Some of the near- surface soils contain moderate quantities of silt and are considered somewhat moisture- sensitive. Therefore, if the subgrade contains too much moisture, adequate recompaction may be difficult or impossible to obtain, and should probably not be attempted before allowing the subgrade to dry/drain adequately. After recompaction of the exposed ground is tested and approved, structural fill may be placed to attain desired grades. Structural fill is defined as non-organic soil, acceptable to the geotechnical engineer, placed in maximum 8-inch loose lifts with each lift being compacted to 95 percent of the modified Proctor maximum density using ASTM:D-1557 as the standard. The majority of on-site soils are suitable for use as structural fill. In the case of utility trench filling, the backfill should be placed and compacted in accordance with current local or county codes and standards. The top of the compacted fill should extend horizontally outward a minimum distance of 3 feet beyond the location of the perimeter footings before sloping down at an angle of 2H:1 V. The contractor should note that any proposed fill soils must be evaluated by AESI prior to their use in fills. This would require that we have a sample of the material 72 hours in advance to perform a Proctor test and determine its field compaction standard. Soils in which the amount of fine-grained material (smaller than No. 200 sieve) is greater than approximately 5 percent (measured on the minus No. 4 sieve size) should be considered moisture-sensitive. Use of moisture-sensitive soil in structural fills should be limited to favorable dry weather conditions. The upper 3 to 4 feet of soil over portions of the site contain more than 12 percent silt. As December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projects120026721KEIWP-W2K Page 8 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations such, some of the site soils are considered moisture-sensitive. In addition, construction equipment traversing the site when the soils are wet can cause considerable disturbance. If fill is placed during wet weather or if proper compaction cannot be obtained, a select import material consisting of a clean, free-draining gravel and/or sand should be used. Free-draining fill consists of non-organic soil with the amount of fine-grained material limited to 5 percent by weight when measured on the minus No. 4 sieve fraction and at least 25 percent retained on the No. 4 sieve. A representative from our firm should inspect the stripped subgrade and be present during placement of structural fill to observe the work and perform a representative number of in- place density tests. In this way, the adequacy of the earthwork may be evaluated as filling progresses, and any problem areas may be corrected at that time. It is important to understand that taking random compaction tests on a part-time basis will not assure uniformity or acceptable performance of a fill. As such, we are available to aid the owner in developing a suitable monitoring and testing frequency. 11.0 FOUNDATIONS Spread Footings Spread footings may be utilized for building support when founded either directly on the medium dense to dense alluvial sand and gravel deposits, or a zone of structural fill that extends down to a depth of 4 feet below the base of foundations or to the medium dense sand and gravel deposits, whichever is less. Structural fill should conform to that described under the Site Preparation and Structural Fill sections of this report. Structural fill placed below footings must extend a minimum of 5 feet beyond the edges of the footings. We recommend that an allowable bearing pressure of 2,000 pounds per square foot (psf) be utilized for design purposes, including both dead and live loads for footings founded either directly upon the medium dense to dense alluvial sand and gravel deposits or structural fill as described above. An increase of one-third may be used for short-term wind or seismic loading. For higher allowable soil bearing pressures, the foundation should be supported by short aggregate piers (Geopiers') as presented subsequently. Perimeter footings for the proposed buildings should be buried a minimum of 18 inches into the surrounding soil for frost protection. No minimum burial depth is required for interior footings; however, all footings must penetrate to the prescribed bearing stratum and no footings should be founded in or above loose or organic existing soils. To limit settlements, all footings should have a minimum width of 14 inches for one-story structures or 16 inches for two-story structures. It should be noted that the area bounded by lines extending downward at 1H:1V from any footing must not intersect another footing or intersect a filled area which has not been compacted to at least 95 percent of ASTM:D-1557. In addition, a 1.5H:1V line extending December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projects1200 2 6 72 1KEIWP-W2K Page 9 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations down from any footing must not daylight because sloughing or raveling may eventually undermine the footing. Thus, footings should not be placed near the edge of steps or cuts in the bearing soils. Anticipated settlement of footings founded as described above should be on the order of 3/4 inch. However, disturbed soil not removed from footing excavations prior to footing placement could result in increased settlements. All footing areas should be inspected by AESI prior to placing concrete to verify that the design bearing capacity of the soils has been attained and that construction conforms to the recommendations contained in this report. Such inspections may be required by the governing municipality. Perimeter footing drains should be provided as discussed under the section on Drainage Considerations. Aggregate Pier Foundations An alternative to supporting the building on a limited thickness of structural fill with a reduced bearing pressure would be to prepare the building pad for construction by installation of short aggregate piers (GeopiersTM). Aggregate piers are constructed by creating a drilled cavity in the matrix soil, and filling the cavity with aggregate that is densely compacted in thin lifts. The compaction typically induces densification in the surrounding matrix soil, and aggregate volumes in excess of the initial cavity volume are expected. Aggregate piers are installed along continuous foundation bearing walls and at spread foundation locations, and may be installed beneath slab-on-grade floor areas, if needed. Following installation of aggregate piers, the site is finish-graded and conventional shallow foundations are constructed above the aggregate piers. If aggregate piers are selected, the pier subcontractor in conjunction with the project structural engineer should provide the final design of the foundation system including the number and locations of piers, depths, diameters, and load bearing capacities. After the piers are designed and constructed, the resulting foundations should yield a bearing capacity of 3,500 to 4,000 pounds per cubic foot (pcf). Pier Inspection The actual total length of each pier will be adjusted in the field based on required capacity and I conditions encountered during drilling. Since completion of the pier takes place below ground, the judgment and experience of the geotechnical engineer or his field representative must be used as a basis for determining the required penetration and acceptability of each pier. Consequently, use of the presented pier capacities in the design requires that all piers be inspected by a qualified geotechnical engineer or engineering geologist from our firm who can interpret and collect the installation data and examine the contractors operations. AESI, acting as the owner's field representative, would determine the required lengths of the piers and keep records of pertinent installation data. A final summary report would then be distributed, following completion of pier installation. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projects12002672IKEIWP-W2K Page 10 it Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report i. Renton, Washington Preliminary Design Recommendations 12.0 FLOOR SUPPORT Slab-on-grade floors can be constructed directly on medium dense to dense alluvium, Geopiers', or a maximum of 2 feet of structural fill compacted to 95 percent of ASTM:D- 1557. Areas of the slab subgrade that are disturbed (loosened) during construction should be recompacted to an unyielding condition prior to placing the pea gravel, as described below. The floor should be cast atop a minimum of 4 inches of washed, uniformly graded granulithic material or pea gravel to act as a capillary break. Areas of slab subgrade that are disturbed (loosened) during construction should be compacted to a non-yielding condition prior to placement of capillary break material. The slab should also be protected from dampness by an impervious moisture barrier or otherwise sealed. The impervious barrier should be placed between the capillary break material and an optional 2- to 3-inch-thick layer of sand. The sand helps to protect the vapor barrier from damage and allows drainage of the slab during curing provided the slab is poured when the sand is dry. Therefore, the sand layer must not be exposed to rain or snow prior to pouring the slab. 13.0 SWIMMING POOL RECOMMENDATIONS We understand a 25-yard, 6-lane lap pool and a wave pool are planned for construction. Since significant excavation for these pools will be required, we recommend the pools be founded on the medium dense to dense gravelly alluvium. We anticipate that construction of the proposed pools will require sloping of the sidewalls of the excavations at slopes of 2H:1V because the cleaner sand within the upper soil horizon will likely not support steeper cut slopes. Therefore, some type of retaining wall or cast-in-place system will be necessary to construct vertical pool side walls. The following section presents appropriate retaining wall design parameters. If some other type of retaining wall or other than a cast-in-place (backfilled) wall is used, we should be provided with pool design drawings to determine if the lateral earth pressures below are appropriate for the proposed design. Ground water was not encountered in our soil borings during our subsurface exploration. However, ground water may rise to elevations high enough to impose hydrostatic pressures on the base and sides of the proposed pools following extended periods of intense precipitation. We installed a piezometer in EB-5 to monitor ground water elevations throughout the winter and spring. Given that the site resides within close proximity to the Cedar River, the pools should be designed with a drainage system to allow for relief of hydrostatic pressure around and beneath the pool. Alternatively, the pool should be designed to accommodate hydrostatic uplift pressures. With ongoing ground water monitoring, it will be possible to estimate a seasonal high ground water level for incorporation into the design. December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/lb-KE02672A3-Projecrs12002672IKEIWP-W2K Page 11 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations 14.0 LATERAL WALL PRESSURES Finished floor elevations were not provided. However, we anticipate that retaining walls may be necessary for the proposed construction. All backfill behind walls or around foundation units should be placed as per our recommendations for structural fill and as described in this section of the report. Horizontally backfilled walls, which are free to yield laterally at least 0.1 percent of their height, may be designed using an equivalent fluid equal to 35 pcf. Fully restrained, horizontally backfilled rigid walls, which cannot yield, should be designed for an equivalent fluid of 50 pcf. If parking areas are adjacent to walls, a surcharge equivalent to 2 �. feet of soil should be added to the wall height in determining lateral design forces. The lateral pressures presented above are based on the conditions of a uniform backfill consisting of on-site sand and gravel soil, compacted to 90 percent of ASTM:D-1557. A higher degree of compaction is not recommended, as this will increase the pressure acting on the wall. A lower compaction may result in settlement of structures, utilities, or concrete pavement placed above the walls. Thus, the compaction level is critical and must be tested by our firm during placement. Surcharges from adjacent footings, heavy construction equipment, or sloping backfill must be added to the above values. Perimeter footing drains should be provided for all retaining walls as discussed under the section on Drainage Considerations. It is imperative that proper drainage be provided so that hydrostatic pressures do not develop against the wall. This would involve installation of a minimum 1-foot-wide washed gravel blanket drain, which is continuous with the perimeter footing drain and extends to within 1 foot of the ground surface. 14.1 Passive Resistance and Friction Factors Lateral loads can be resisted by friction between the foundation and the natural alluvial soils or supporting structural fill, or by passive earth pressure acting on the buried portions of the foundations. The foundations must be backfilled with structural fill and compacted to at least 95 percent of the maximum dry density to achieve the passive resistance provided below. We recommend the following design parameters: • Passive equivalent fluid = 250 pcf • Coefficient of friction = .35 The above values are allowable and include a safety factor of at least 1.5. 15.0 DRAINAGE CONSIDERATIONS The majority of on-site soils will likely provide adequate drainage during post-construction heavy precipitation events. However, some method should be in place to contain any storm December 2, 2002 ASSOCIATED EARTH SCIENCES, INC. SGB/Ib-KE02672A3-Projects12002672IKEIWP-W2K Page 12 Subsurface Exploration, Geologic Hazard, and Renton Aquatic Center Preliminary Geotechnical Engineering Report Renton, Washington Preliminary Design Recommendations water runoff and discharge it to a suitable collection system during the earthwork portion of construction in the event that runoff does occur. Therefore, prior to site work and during construction, the contractor should be prepared to provide temporary storm water storage or discharge mechanisms as necessary. All retaining and footing walls should be provided with a drain at the footing elevation. Drains should consist of rigid, perforated, PVC pipe surrounded by washed pea gravel. The level of the perforations in the pipe should be at the bottom of the footing at all locations and the drains should be constructed with sufficient gradient to allow gravity discharge away from the building. In addition, all retaining walls should be lined with a minimum 12-inch-thick washed gravel blanket provided over the full height of the wall, and which ties into the footing drain. Roof and surface runoff should not discharge into the footing drain system but should be handled by a separate, rigid, tightline drain. In planning, exterior grades adjacent to walls should be sloped downward away from the structure to achieve surface drainage. 16.0 PAVEMENT RECOMMENDATIONS Based on our current understanding of the project, construction of new asphalt pavement is not planned. However, site surfacing will likely consist of concrete pavement. Site preparation for these areas should consist of overexcavating to remove the existing vegetation, topsoil, and any loose/soft upper soils to expose the underlying stable soils. Since the density of the upper soils is variable, random loose/soft areas may exist and the depth and extent of stripping can best be determined in the field by the geotechnical engineer. To limit differential settlement and cracking of the concrete pavement, we recommend overexcavating areas to receive concrete by 18 inches and replacing this material with compacted structural fill. The excavated soils can be used as fill provided the moisture content at the time of compaction allows for the minimum specified compaction. In addition, the subgrade should be slightly inverted to drain toward the catch basins or surface drains. After the area to be paved is overexcavated, the exposed ground should be recompacted to 95 percent of ASTM:D-1557. Structural fill may then be placed to achieve desired subbase grades. Upon completion of the recompaction and structural fill placement, the recommended minimum pavement section is 6 inches of reinforced concrete pavement underlain by 4 inches of 11/4-inch minus crushed rock base course with less than 3 percent material retained on the No. 200 sieve. The crushed rock course must be compacted to 95 percent of the maximum density. 17.0 PROJECT DESIGN AND CONSTRUCTION MONITORING At the time of this report, site grading, structural plans, and construction methods have not been developed. Therefore, the recommendations presented herein are preliminary. We are December 2, 2002 ASSOCIATED EARTH SCIENCES, INC.

We recommend that AESI perform a geotechnical review of the plans prior to final design completion. In this way, our earthwork and foundation recommendations may be properly interpreted and implemented in the design. We are also available to provide geotechnical engineering and monitoring services during construction. The integrity of the foundation depends on proper site preparation and construction procedures. In addition, engineering decisions may have to be made in the field in the event that variations in subsurface conditions become apparent. Construction monitoring r services are not part of this current scope of work. If these services are desired, please let us know and we will prepare a cost proposal.
