There are currently no funds budgeted for obtaining the right-of-way. Therefore, to compensate Benaroya in exchange for the deed of dedication, the Utilities Committee recommends concurrence in the Planning/Building/Public Works Department's recommendation to: a. Waive OFFSET 100% of the Grantor's Surface Water Utility system development charge that may become due for the SW 16th Technical Center proposal (File No. SA-96-034); b.

Site is located adjacent to Springbrook Creek and requires Shoreline Substantial Development Permit as well as Site Plan Approval. SUMMARY OF ACTION: Development Services Recommendation: Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on May 8, 1996. 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 May 14, 1996 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,May 14, 1996, at 9:07 a.m. in the Council Chambers on the second floor of the Renton Municipal Building. 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: Proposed site plan application, proof of posting, proof of publication and other documentation pertinent to this request.

The original applicant for this Site Plan Approval, Shoreline Permit and environmental review was Group Health Cooperative. There has been a change of ownership and now it is owned by the Benaroya Corporation. This is a 22.5 acre site in the Green River Valley portion of the City. The surrounding streets are SW 16th on the north and Raymond Avenue SW on the east. The western boundary is defined by Springbrook Creek. The southern boundary would be defined by SW 19th if it went through. The applicant is requesting Site Plan Approval for the redevelopment of the site. The site is currently being used by Group Health Cooperative for the purposes of warehousing, offices,medical laboratories and a distribution center. There is existing site development that is located in the northeast corner. Currently there is 93,000 square feet of development in one building plus two smaller metal buildings, for a total of about 97,000 square feet. The two metal buildings and 8,000 square feet of the existing building(Building B)will be removed. An addition of 208,000 square feet to Building B is 1 then proposed. A second building(Building A)would be 126,000 square feet. The addition to Building B would extend it to the west and south, and the new Building A would be located on the western portion of the triangular shaped parcel. The storm water facilities would be located in the very southern portion of the site and would include facilities for both treatment and detention of storm water. This particular project is speculative. The buildings are being proposed for high tech office research and development and no tenants have been identified, although the applicant has been in negotiations with at least one tenant. While it is 'speculative, staff feels confident that the applicant is going to go forth with this project. The total site development in terms of built area would be about 419,000 square feet and would be leasable area. There would be dock high loading doors on the western facade of Building A and the new construction would also feature a building that consists of tilt-up concrete construction with wood roofing. The building would have stepbacks on each facade to try and diminish the bulk of the building. There would be parking for 624 vehicles which meets the City's requirement. The parking lots would be located on the perimeter of the buildings and between the two buildings. There would be new access driveways on SW 16th and on Raymond Avenue SW. Currently there are two driveways on each side. The project site is involved in a Comprehensive Plan amendment and rezone. If it went through it would change this particular designation to a manufacturing designation. However,this proposal would meet the requirements of either zone based on the way it is being designed right now. To develop this site,the applicant needs to import up to 75,000 cubic yards of material. This fill would be used as preload to elevate the building above the flood plain. The applicant has indicated they would like to begin preloading this summer if they are able to obtain all necessary permits and approvals. The surrounding sites that have been developed or have been proposed are office and light industrial land uses. The bank of Springbrook Creek on the western edge of this property is very steep and the vegetation along the creek is currently dense brush. The proposed buildings for this project would be set back a minimum of 50 feet from the ordinary high water line. There would be no clearing,no grading or other disturbance as part of this project that would occur within 25 feet of the mean high water mark for the creek. Since this project is within 200 feet of the creek, it does require a Shoreline Substantial Development Permit. That is not part of this hearing today, but is an administrative action, and ultimately is approved by the State Department of Ecology. There is a small unregulated stream called Rolling Hills Creek at the southern portion of the site, and that is not subject to any kind of shoreline permits or other regulation. Edi Linardic/LDG Architects SW 16th Center R&D Technical Center ;File No.: LUA-96-034,SA,SM June 3, 1996 Page 3 This site is within the Valley Planning Area. The Soil Conservation Service has an agreement with the City that requires the applicant retain at least 2 percent of the site as natural landscaping. The applicant has retained approximately 6 percent of the site, so they have more than three times met the minimum requirement. The proposal is also located within the Pacific Flyway and has been identified as an area where raptors sometimes perch. The applicant has proposed to temporarily locate perch poles in areas on the site where any clearing might impact vegetation that is currently used for raptor perching. When proposed vegetation is established enough that it is suitable for perching habitat,those perch poles would be removed. There are three wetlands on the southeastern edge of the site. Wetland C is regulated by the City wetlands ordinance and is almost 17,000 square feet in size. The two smaller wetlands are less than 5,000 square feet in size. All of these wetlands are considered to be Category 3. Because wetlands A and B are less than 5,000 square feet in size,they are not regulated, and the applicant is able to fill those and has planned to do so. The applicant has proposed a building to go in the location where wetland C is located. In order to do that they need to participate in the wetlands mitigation bank, and the Public Works Administrator has approved participation in the bank. The largest wetland is going to be recreated on the site of the wetlands mitigation bank, but in an j area that is not regulated by the Corps of Army Engineers. SCOTT WOODBURY, Project Manager, Surface Water Utility, City of Renton, 200 Mill Avenue South, Renton, Washington 98055, addressed several issues. He explained that with regard to the flood plain,the City is working with the applicant to acquire some additional right-of-way along the creek for the future widening of Springbrook Creek. One of the agreements reached in exchange for that right-of-way is the City will provide the compensatory storage for this proposed project. The City completed a channel widening project just downstream of the site in 1995. As part of that project approximately half of the applicant's compensatory storage requirement was created. The balance of the compensatory storage would be compensated as part of the future project. The widening of Springbrook Creek from 16th Street to 23rd Street is identified in a current proposal,the East Side Green River Watershed Project. An application was submitted in December 1995 for this comprehensive surface water drainage project which includes a channel improvement along this reach from 16th to 23rd Street. So,the storage that is temporarily lost on this site in no way would increase flows to the stream in a way that 16th Street to Grady did not mitigate for. The Examiner asked why this applicant achieved a variance from the additional wetland compensation--if a wetland of 16,000 square feet were to be removed, 24,000 square feet of new wetland would normally be required. Mr. Woodbury explained that the wetlands ordinance has provisions for reducing the mitigation ratios provided certain criteria are met. One of the criteria is if wetland fills are mitigated so that the separate wetland fills are consolidated into a single wetland mitigation,then a lower mitigation ratio is allowed. 1 Ms.Henning explained that the southern half of this particular subject parcel is located within the 100 year flood plain and the project must have compensatory storage or provide it if not. The applicant's proposal does 'result in displacement of flood waters. There is sufficient compensatory storage in Springbrook Creek and that has occurred as part of recent projects. The City is asking for 55 feet on either side of the creek. They need a total width of 140 feet. The channel width is currently 40 feet,then they need another 50 feet on either side of the creek. The applicant has revised the size of Building A slightly and agreed to set an area in reserve on the northwestern corner to accommodate the widening of Springbrook Creek and also to accommodate the possible future extension of Oakesdale Avenue SW. Edi Linardic/LDG Architects SW 16th Center R&D Technical Center File No.: LUA-96-034,SA,SM June 3, 1996 Page 4 This project has gone through environmental review and received a Determination of Non-Significance- Mitigated. The first mitigation measure required applicant file a final wetland management plan that was acceptable to the City and that would mitigate for the filling of the large wetland C. The applicant submitted their plan to fill the wetland and have the site recreated in an off-site area. They proposed paying the City$3.00 per square foot of replaced wetland to participate in the wetland mitigation bank. It has been accepted by the City. The second mitigation measure requires payment of the appropriate fire mitigation fee. That fee for industrial and commercial structures is$.52 per square foot of new construction and credit can be given for areas that are demolished of existing structures. Those fees are payable prior to the issuance of the building permit. The third mitigation measure requires payment of the traffic mitigation fee. That is assigned at a rate of$75 per each new average daily trip that is attributable to the project. There can be credit given for existing trips on the site that might be eliminated with the new proposal. Finally,the applicant is going to be required to limit construction traffic on adjacent arterials during their preloading activities to the hours of 8:30 a.m. to 3:30 p.m. In terms of a site plan criteria,the applicant's proposal does meet the requirements of the policies that secondary uses in the category include a mix of commercial and light industrial activities. Since this site would be used for office,manufacturing,warehousing, research and development facilities, it would be consistent with allowed primary and secondary uses in the zone and the land use designation. Policies and objectives also call for quality development in this area, and this particular proposal would develop the site with additional buildings. There would be parking circulation and landscaping. It would complement existing office and warehouse development in the area. The setback,heights and lot coverage requirements are within the standards in this zone. An environmental policy that applies to the project is the location of developments in the 100 year flood plain. Roads and finished floors of structures must be located above the existing 100 year flood level, and new development must provide compensation for existing flood storage capacity due to filling. The applicant is going to set their floor elevations to meet City regulations. There is compensatory storage that is being provided. It is being accommodated by the City and part of this is in negotiation with the applicant for giving over area that can be used for the widening of Springbrook Creek. The applicant has proposed 20 feet of landscaping along SW 16th and also Raymond. The project also meets the required 2%of natural landscaping for the Soil Conservation Service agreement with the City. In fact,the applicant is providing nearly 60,000 square feet of natural landscaping where the requirement would be about 19,500. Primarily this is going to be located along Springbrook Creek. The CO zone requires there be a pedestrian connection between public entrances to streets unless the Hearing Examiner determines that this requirement unduly endangers pedestrians. The applicant's plan has not indicated striped crossings or other suitable pedestrian connections from the buildings out to the streets, but staff recommends that this be required as a condition of approval. The Examiner inquired about the timing on the wetland compensation and whether the wetland bank would be opened for withdrawal when this wetland is filled. Mr. Woodbury explained that the City is in the process of completing a wetland mitigation banking program,but the net result might be a temporary loss of two to three years of certain wetlands. Ms. Henning stated that this particular redevelopment of the site would conserve and enhance property values by providing a project that has office,research and development, and manufacturing, and includes sufficient Edi Linardic/LDG Architects - SW 16th Center R&D Technical Center File No.: LUA-96-034,SA,SM June 3, 1996 Page 5 perimeter and interior site landscaping with extensive buffering. The proposed development would be similar in scale and character to existing Valley development. 1 The applicant is going to be providing site lighting that provides for security in the parking lots during evening hours. They are proposing shielded lights so that there is no spill-over impacts to areas where raptors would be nesting or to the creek areas and such. There is water, sewer, and storm service available to applicant. There may be a number of people working on the site who might be seeking some sort of recreation during their breaks and applicant has provided outdoor eating areas. Staff is asking for active recreation for the site such as a basketball hoop, and believes there is sufficient area to accommodate that. The architecture proposed and the installation and maintenance of landscaped areas would prevent neighborhood deterioration and blight. There would be areas held in reserve for the widening of Springbrook Creek and the Oakesdale extension. Those would need to be maintained by the applicant, owner or the tenant of the development. Staff is recommending approval of the site plan with conditions attached. The first would be compliance with the ERC mitigation measures. The second would be appropriate pedestrian connections between the two proposed buildings and also out to the sidewalks on SW 16th Street. These would be tied to the building permits and must be submitted as part of the building package drawing. In addition, staff is recommending that the site plan be revised to indicate the number and location of the raptor perch poles prior to the issuance of any construction permits. Staff is asking submittal of a lighting plan which would indicate where the lights would be located,the type of lighting used, and demonstrate that there would be appropriate shields on the lights to prevent spill-over lighting, especially in regard to Springbrook Creek. The final condition is for the provision of on-site recreation areas. The Examiner asked where the entrances to the buildings were located as a focal point, and Ms. Henning responded that typically the offices would be located at the corners where the extensions of the building were, and that is where a few small raised walkways have been proposed by the applicant. TOM LEE, O'Keefe Development, 7900 SE 28th Street, #400,Mercer Island, Washington 98040, spoke on behalf of the applicant. He stated that they had worked closely with the City and the neighbors of the project site to comply with not only the Oakesdale extension, but the Springbrook Creek widening as well. He indicated that although currently this is a speculative research and development center, applicant was talking with several possible tenants and hoped by the middle of summer to come to resolution on that. With regard to the major focal point for the office area of the larger building, it would be to the north end which is where the main entry to the Group Health facility is located at this time. 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 10:15 a.m. FINDINGS, CONCLUSIONS &DECISION Having reviewed the record in this matter,the Examiner now makes and enters the following: FINDINGS: Edi Linardic/LDG Architects SW 16th Center R&D Technical Center File No.: LUA-96-034,SA,SM June 3, 1996 Page 6 1. The applicant, Edi Linardic(LDG Architects), filed a request for approval of a Site Plan Approval and a Shoreline Substantial Development permit for office/warehouse buildings. 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 Determination 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. The subject site is located at 801 SW 16th Street. The subject site is on the southwest corner of the intersection of 16th and Raymond Avenue SW. The existing building on the site was used as the Group Health Distribution Warehouse. That building will be incorporated into a larger building and a second building will be added to the west. 6. The subject site was annexed to the City with the adoption of Ordinances 1745 and 1764 enacted in April and May, 1959 as amended by Ordinances 1928 and 4040 enacted in December 1966 and February 1987. 7. The subject site received its CO(Commercial Office)designation with the adoption of Ordinance 4404 enacted in June 1993. 8. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of commercial,employment generating uses,but does not mandate such development without consideration of other policies of the Plan. 9. The subject site is an approximately 22.4 acre,triangular shaped parcel. Its southeast to northwest angling western property line is defined by Springbrook Creek. 10. The applicant proposes expanding portions of the existing building,Building B, from 85,000 square feet to approximately 208,000 square feet. A portion of the existing building and an out-building would be demolished. The addition would be added to the southern side of the current structure. The building would have articulated facades. It would be approximately 850 feet long(north to south)by approximately 400 feet wide. It would be approximately 31 feet tall. 11. Proposed Building A would be approximately 126,000 square feet. It would also have an articulated facade. It would be 31 feet tall. It would be approximately 520 feet long(north to south)by approximately 250 feet wide. 12. The buildings will each be of tilt-up concrete construction,with bay delivery doors. The buildings will have some modulations concentrated near their respective corners. There will be horizontal accent trim and metal trimmed window and door panels. The applicant proposes outside eating patios near the northwest corner of each building. 13. Parking for 624 vehicles will be provided around the buildings. There will be parking along the west, north and east property lines as well as parking between the buildings. The parking areas will be landscaped. Edi Linardic/LDG Architects SW 16th Center R&D Technical Center File No.: LUA-96-034,SA,SM June 3, 1996 Page 7 14. Both buildings will observe approximately 90 foot setbacks from SW 16th Street. Building B will be setback approximately 115 feet from Raymond. 14. The applicant proposes three driveways along Raymond and an additional three driveways along 16th to serve the site. 15. Three small wetlands on the site will be filled with approval of the City. The wetlands are concentrated along the eastern boundary of the site with one immediately south of the existing building. The other two are located near the southeast corner of the site. The applicant will be partaking of the City's wetland bank to provide compensatory wetlands and with variance approval from Public Works it will be on a one to one level. 16. The site is within the Pacific Flyway for migrating birds and raptors are known to perch in the area. The applicant will be providing raptor poles subject to both City and State review. 17. The site is located in the 100 year flood plain. The applicant proposes flood proofing the site by raising the building elevations above the flood plain by filling the site. This fill material would displace flood waters from the site potentially creating additional flood problems for other sites. Staff notes that there should be sufficient capacity for storm water in the proposed widened Springbrook Creek but that project is in the planning stage. Staff also notes that the existing channel probably has sufficient capacity. There is nothing that entitles this applicant to use that City resource and the applicant is required to accommodate its storm water. 18. The applicant has provided an area in reserve that may be used to accommodate the eventual widening of Springbrook Creek and the construction of Oakesdale Avenue. The area in reserve is located in the northwest corner of the site. 19. Staff recommended that the applicant provide active recreational amenities on the subject site in the form of a basketball hoop. CONCLUSIONS: 1. 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; Edi Linardic/LDG Architects SW 16th Center R&D Technical Center File No.: LUA-96-034,SA,SM June 3, 1996 Page 8 The proposed use satisfies these and other particulars of the ordinance. 2. In the main,the proposed site plan appears appropriate and should be approved. 3. The mixed office/manufacturing/warehouse use is compatible with the Comprehensive Plan's designation of commercial and employment generating uses, although warehousing is space consumptive without providing a large employment base. 4. The proposed buildings comply with the height, setback, lot area coverage and use limitations of the Zoning Code. Building Code compliance will be established when the applicant submits its plans for a building permit. 5. The generally low-rise nature of the buildings will not create any adverse shadow impacts on surrounding property. The large mass of the buildings should be relieved somewhat by the exterior treatment, landscaping and the articulations found near the corners of the buildings. 6. What needs to be addressed is the impact on the flood plain and the loss of wetlands. More specifically,the timing of the improvements and proposed compensation_needs to be reviewed. It would seem inappropriate to fill wetlands if the compensating wetlands were not provided in a timely fashion. While the filling of the small wetlands areas has been approved,the loss of habitat should not have to wait years as the wetlands'bank issues are fine tuned. The loss of habitat will force migratory species elsewhere or cause their loss if appropriate habitat is not established in a simultaneous fashion. The nesting of raptors may be associated with the wetlands and the loss of these small wetlands might- alter the raptors' hunting habits. The recreation of nesting poles will help but their prey might be less frequent. Therefore,the applicant shall be required to provide compensation as near as possible in time to the filling. 7. In a similar fashion,the filling of the site requires compensating storage of flood waters or they could be displaced onto adjoining parcels that would not normally be affected by flooding. The site is in the 100 year flood plain and any filling must be accompanied by compensatory storage. While there supposedly is excess capacity in the Springbrook Creek system, it does not appear that the applicant is entitled to its long term use. Since staff was not sure that potential projects to widen Springbrook Creek are certain,the applicant shall be required to demonstrate that it can fully accommodate its storm drainage requirements,that is, a full design for compensation, its location and suitability is necessary. 8. Again,the proposed site plan appears to be generally well-laid out. The buildings,particularly the larger Building B,will be quite large,but as noted,the landscaping, including the additional required for habitat mitigation, will soften the impact on the site. 9. The redevelopment of the existing building and the addition of a new building should not adversely affect property values. 10. The applicant will need to clearly delineate pedestrian crossings of the parking areas. This should be done with a change of pavement materials so that it is more permanent than painted markings. The six driveways should accommodate the traffic flow and staff indicated that impacts on the corridors should not be adverse. 11. There are adequate public services to serve the site. • 1 Edi Linardic/LDG Architects • 1 SW 16th Center R&D Technical Center File No.: LUA-96-034,SA,SM June 3, 1996 Page 9 12. In conclusion,the overall project is appropriate although more office space would probably create additional jobs, but warehousing of products is an essential aspect of business and commerce. DECISION: The proposed Site Plan is approved subject to the following conditions: 1. The applicant shall comply with the conditions imposed by the ERC. 2. The applicant shall be required to demonstrate that it can fully accommodate its storm drainage requirements,that is, a full design for compensation, its location and suitability is necessary. 3. The applicant shall be required to provide compensation wetland as near as possible in time to the filling. 4. The applicant shall provide pedestrian paths that delineate crossing of the driveways/parking aisles by using a different paving material. 5. The applicant shall provide raptor poles subject to both City and State review. 6. The applicant shall provide an active recreation area that is shared by both buildings. 7. The applicant shall provide a lighting plan for the site. 8. There shall be no preloading of the site until the applicant has been granted a building permit. The applicant shall post a bond to assure that either the preload material is removed from the site or compensatory storage can be provided if development as approved does not occur.

Warren, City Attorney James Chandler, Building Official Transportation Systems Division Jay Covington, Mayor's Executive Assistant Utilities System Division Councilperson Kathy Keolker-Wheeler Valley Daily News 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., June 17, 1996. 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. Appeal of the Examiner's decision is governed by Title IV, Chapter 8, Section 11, which requires that such appeal be filed with the Superior Court of Washington for King County within twenty (20) days from the date of the decision. 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. ,:;,.

A new one-story structure (Building "A") and an addition to an existing structure (Building "B") and parking for 624 vehicles would be provided. Building "A"would be 126,000 square feet in size, while Building "B" would result in the addition of 208,000 square feet to an existing 85,000 square foot building. Total size of both buildings would be 419,000 square feet. Anticipated use of the structures is office, research and development, manufacturing and warehouse. Landscaping would be provided on the perimeter of the site, around the buildings and within the parking areas. Existing natural landscaping would remain along the western boundary of the site which is adjacent to Springbrook Creek. On-site employee outdoor recreation/seating areas would be provided. Buildings would be setback a minimum of 65 feet from the Ordinary High Water Mark for Springbrook Creek, and no disturbance would occur as a result of the project within 25 feet of the mean high water mark of the creek. The proposal would not preclude access to Springbrook Creek. Visual access would be available from SW 16th Street on the north side of parcel. Physical access would be possible from SW 16th Street. In addition, future City of Renton public works projects (as discussed below)would accommodate public access to and along the Creek. The Site Plan indicates an area in the northwest corner of the property that would be set aside as a reserve to be dedicated to the City of Renton for the future extension of Oakesdale Avenue SW through the site. In addition, a 55-foot wide area from the western 5-foot contour of Springbrook Creek would be granted as an easement or dedicated by the property owner to the City of Renton for the widening of Springbrook Creek. The City would need to obtain a separate Shoreline Substantial Development Permit for either the Oakesdale extension or the SHSBDV.DOC • • " City of Renton P/B/PW Department Shoreline Substantial Development Permit Page 2 of 4 widening of Springbrook Creek. A shelf would be created along the Creek as part of the widening project and could be used for visual and physical public access to and along Springbrook Creek. Three wetlands are present on the site. Two small Category III wetlands are not regulated and would be filled. A third Category III wetland (approximately 16,000 square feet in size) would be filled and recreated off-site. The site is located adjacent to Springbrook Creek and Rolling Hills Creek. Springbrook Creek is considered to be a "Shoreline of the City" and is regulated under the Shoreline Master Program. The Shoreline Boundary Map for Springbrook Creek shows that "Urban" and "Conservancy" designations apply to the site. (The Shoreline Boundary Map was developed based on a Department of Ecology windshield survey of the area.) "Urban" environment designations are intended for high-intensity land uses including residential, commercial, and industrial development. "Conservancy" environments are intended for passive uses and were intended to account for the presence of Category I or II wetlands. Wetland studies conducted by a qualified wetlands biologist included delineation of three wetlands on the subject parcel. Each of these three wetlands was determined to be classified as a Category III wetland, according to the Renton Wetlands Ordinance. Based on the wetland studies conducted for the subject site (Attachment "A") the "Conservancy" designation is not an appropriate designation for any portion of the property. For this reason, the Shoreline Substantial Development Permit considers only the "Urban" designation as applying to the site, and will seek to amend the Shoreline Boundary Map for Springbrook Creek.

Route 153 operates on SW 16th St. Metro has a bus zone on SW 16th St.just west of Raymond Ave. SW. As it appears that the developer will be installing new curb, gutter and sidewalk in this area, staff request that the developer coordinate with King County Transit to maintain the current location of the zone both during and after construction. Please consult with Paul Alexander, Facilities Planner, at 684-1599 to discuss maintaining the zone as these improvements are made. In addition to the improvements discussed above, the project proponent should be required to provide pedestrian access from Building A and the existing building to SW 16th St. to facilitate the use of transit. Please note that Commute Trip Reduction requirements are likely to apply, at some point, to this project. If you have any questions or comments, please contact Ann Martin, Transit Planner, at 296-6509. Thank you for the opportunity to review and comment.

USE OF PORTION OF OAKESDALE WETLAND AREA TO SATISFY BENAROYA MITIGATION OBLIGATION The City is obligated to provide 16,700 square feet (0.38 acres) of wetland mitigation for the Benaroya's SW 16th Street Technical Center project (LUA-96-034). In exchange Benaroya paid the City$50,100 in lieu of having to construct the mitigation on their development site. The intent of the City was to use the money to construct the mitigation as part of the City's mitigation bank construction project. Under current design plans, the Oakesdale Phase lA project (LUA-95-024) will create about 2 acres of wetland. This is about 1.5 acres in excess of what is required for the Phase 1A wetland impact. The excess 1.5 acres was intended to be reserved in partial satisfaction of the approximately 3 acres of mitigation needed for Phase 2, with the remaining 1.5 acres of Phase 2 mitigation being accomplished on a separate site at the time Phase 2 is implemented. However, it was agreed that the Benaroya mitigation money should be transferred to the Oakesdale project in 1997 in exchange for use of 0.38 acres of the excess wetland to be created under Phase 1A. Thus the Benaroya mitigation requirement is satisfied and the cost of the Oakesdale project is reduced by $50,100. The Benaroya mitigation would also be completed 2 years earlier than if the mitigation was accomplished under the City's mitigation bank construction project, currently scheduled in the SWU Capital Improvement Program for the year 2000. The $50,100 also covers all monitoring, maintenance, and other post-construction activities that may be necessary to ensure that the wetland mitigation is successful. Post-construction activities will be conducted by the Transportation Division in accordance with the Wetland Mitigation Plan approved for the Oakesdale Extension Project. Linda Honeycutt Interfund Transfers Page 2 The total transfer is$50,100 and is to be transferred in 1997 between the following accounts: DEBIT: 421.000600.018.5960.0038.65.065119/25105/5100 $50,100 Surface Water Utility account/WO/function CREDIT: 317.000022.016.5950.0011.67.000000/25 1 05/5 1 60 $50,100 Transportation account/WO/function SPRINGBROOK CREEK CHANNEL WIDENING DESIGN REIMBURSEMENT The Springbrook Creek channel from SW 16th Street to the proposed Oakesdale bridge crossing will be widening as part of the Oakesdale Avenue SW Extension Project. In addition to designing the roadway, the engineering consultant team for the Oakesdale project, lead by Kato & Warren, also prepared the design plans and specifications for the channel widening work under their contract (CAG-97-061)with the Transportation Division. The Surface Water Utility(SWU)will reimburse the Transportation Division for the SWU's share of the costs of the channel widening design work. The total cost has not yet been determined. However, the SWU wishes to make an initial $25,000 payment this year to reimburse a portion of the cost. Therefore,please process a transfer for$25,000 between the following accounts: DEBIT: 421.000600.018.5960.0038.65.065285/25105/5160 $25,000 Surface Water Utility account/WO/function CREDIT: 317.000022.016.5950.0011.67.000000/25105/5160 $25,000 Transportation account/WO/function We request that the transfer be made before the end of the year so it is paid out of 1997 funds.

The final calculation for the floodplain storage filled by the Technical Center project is attached. The calculation shows that 213,246 cubic feet of floodplain was filled by the project, which is less than originally expected. A net volume of 61,544 cubic feet of storage was created by the project, excluding the volume of storage needed to satisfy the project's detention requirement. This results in a net fill of 213,246-61,544=151,702 cubic feet. As a condition of obtaining property along Springbrook Creek from the Technical Center site, the City agreed to provide compensatory storage for the Technical Center project's floodplain fill (see Hearing Examiner's report for site plan approval dated June 3, 1996, and CAG-96-092). A total of 175,000 cubic feet of floodplain storage was created in 1995 just downstream of the Technical Center site as part of the Springbrook Creek widening project from SW Grady Way to SW 16th Street. Thus,the compensatory storage created exceeds that filled by 23,298 cubic feet. The excess 23,298 cubic feet may be used to offset floodplain fill impacts of other projects for which the City is obligated to provide compensatory storage.

(Petition) Mr. Tilton explained that NE 6th Street is the only through street between Monroe and Union that does not have stop signs. He added that the problem with speeding vehicles along this street has been recently exacerbated by increased housing development in this area, which has worsened what is already a dangerous situation for residents and their pets. Councilmember Nelson agreed this was a problem, particularly since NE 6th Street is narrow and not intended for use as a thoroughfare.

The necessary rights have been acquired to extend Oakesdale Avenue SW through the Benaroya property at SW 16th Street. The negotiations for the area needed included a request from the Benaroya company to release the Restrictive Covenant as it is no longer needed. The request was circulated within the Planning lBuilding\Public Works Department verbally. The response was uniformly unconditional approval with the comments that the Benaroya Company was very cooperative during negotiations and dealt fairly with the City, since the property rights held in the restrictive covenant are no longer needed the request should be granted and the restrictive covenant released.

In addition, the applicant requested that a waiver be granted to allow a wetlands replacement ratio of 1:1 rather than the required 1.5:1 replacement ratio, and that the replacement occur after the subject wetland has been filled. The requests were granted subject to the following conditions: 9. There shall be compensation payment in the amount of$3.00 per square foot of replaced wetland for participation in the in the wetland mitigation bank prior to the issuance of a Building Permit. 2. There shall be a one year period from this approval where full or partial refunds could be made to the applicant if the City substantially alters the Wetland Management Ordinance in such a way that minimizes or deletes the need for compensation for filling of the subject wetland during this time period. The decision has a reconsideration/appeal period connected to it that ends on Tuesday, May 14, 1996 at 5:00 pm. 2. The applicant shall pay the appropriate Fire Mitigation Fee at a rate of $0.52 per square foot of new construction. (Credit may be given for area of demolished structures.) This fee is payable prior to the issuance of the Building Permit. The applicant will need to comply with this requirement prior to the issuance of a Building Permit. 3.

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 Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH SITE PLAN APPROVAL CRITERIA Section 4-31-33 (D.) "The Hearing Examiner and City staff 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 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:" GENERAL CRITERIA: A. CONFORMANCE WITH THE COMPREHENSIVE PLAN, ITS ELEMENTS & POLICIES Policy LU-184. Secondary uses in the category should include a mix of commercial and light industrial activities. The proposal would result in the development of the site for office, manufacturing and warehouse uses, consistent with allowed primary and secondary uses in the Commercial Office Zone and Employment Area- Office land use designation. Objective LU-DD: Ensure quality development in the Employment Area-Office areas. The applicant would develop the site with buildings, parking, circulation and landscaping that would complement existing development in the area. Policy LU-190. Parking should be provided on-site, in parking structures, and buffered from adjacent uses. On-site parking for 624 vehicles would be provided. Landscaping would be provided in minimum 20-foot wide beds along SW 16th Street and Raymond Avenue SW. Landscaped planter areas would be located along building facades and within parking areas. The proposed landscaping would consist of ornamental trees, shrubs, groundcover and sod lawns and would effectively buffer the site from adjacent uses. Policy LU-192. Vehicular access to the site should be the major street with the access points minimized but designed to ease entrance and exit. Three access drives would be provided from SW 16th Street, and three access drives would serve the site from Raymond Avenue SW. The driveways would be redesigned from the current configuration replacing the two existing curb cuts on SW 16th Street. Two new curb cuts would be installed along Raymond Avenue SW, and one existing curb cut would continue to access the site. Another existing curb cut would be eliminated on Raymond Ave SW. HEXRPT.DOC • City of Renton P/B/PW Department — . Preliminary Report to the Hearing Examiner SW 16th STREET R&D TECHNICAL CENTER LUA-96-034, SA, SM, ECF PUBLIC HEARING DATE: May 14, 1996 Page 7 of 11 Policy EN-13. When development may impact wetlands the following hierarchy should be followed in deciding the appropriate course of action: a. avoid the impacts to the wetland, b. minimize impacts to the wetland, c. restore the wetland when impacted, d. recreate the wetland at a ratio which will provide for its assured viabilityand success. The applicant applied for and received approval to participate in the City's Wetlands Mitigation Bank for the recreation of the wetland at a 1:1 ratio in an off-site location. The applicant's responsibility is to provide financial compensation for the wetland area to be filled. The amount has been determined to be $3.00 per square foot of replaced wetland. The wetland area affected by this determination is one (approximate) 16,700 square foot wetland located at the southeast portion of the subject parcel. Policy EN-19I. Limit development within the 100-year floodplain to that which is not harmed by flooding. Roads and finished floors of structures should be located above the 100-year flood level and new development should provide compensation for existing flood storage capacity due to filling. The applicant will set floor elevations to meet City regulations to be above the flood plain. Compensatory storage would be accommodated through the City's Springbrook Creek widening project. Should the widening of Springbrook Creek not occur, the applicant would need to provide compensatory flood storage on the project site. B. CONFORMANCE WITH EXISTING LAND USE REGULATIONS The following requirements and development standards contained in Section 4-31-16 Commercial Office Zone (CO) of the Interim Zoning Code [adopted June 1993) are applicable to this proposal. 1. SETBACKS Buildings in the CO Zone must be setback a minimum of 15 feet from the front yard, while minimum street setbacks are based on building height. Proposed buildings would be approximately 31 feet in height. For structures that are from 25 to 80 feet in height, the minimum setback from the street is 20 feet. Buildings proposed on the subject parcel comply with the minimum setback as they would be set back a minimum of 90 feet from the surrounding streets. Maximum setbacks in the CO Zone have recently been eliminated from the Code under Ordinance No. 4593 (April 1, 1996). 2. HEIGHT Allowed heights in the CO Zone are 250 feet. The proposal would include building heights of approximately 31 feet, and would comply with the development standards. 3. LOT COVERAGE The CO Zone allows 65% lot coverage. The proposal would result in 43% lot coverage and could comply with the development standard. 4. PARKING REQUIREMENTS: Chapter 14, Title IV The developer has indicated that the 419,000 square foot development would include 131,000 square feet of office, 111,000 square feet of manufacturing use, and 177,000 HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Hearing Examiner SW 16th STREET R&D TECHNICAL CENTER LUA-96-034, SA, SM, ECF PUBLIC HEARING DATE: May 14, 1996 Page 8 of 11 square feet of warehouse. The Parking and Loading Ordinance requires a minimum of three parking spaces per each 1,000 feet of gross floor area, and not more than 4.5 parking spaces per each 1,000 square feet of gross floor area. Manufacturing, research and testing uses are requires to provide a minimum of 1 parking space for each 1,000 square feet of gross floor area, and not more than a maximum of 1.5 spaces per 1,000 square feet of gross floor area. Warehouse use must provide a parking space for each 1,500 square feet of gross floor area. Based on these requirements, the applicant would need to provide a minimum of 393 and a maximum of 590 parking spaces for the office use; a minimum of 111 and a maximum of 167 parking spaces for the manufacturing use, and 118 parking spaces for the warehouse use. Therefore, the total required parking for the proposal is a minimum of 622 parking spaces and a maximum of 875 parking spaces. The applicant has proposed 627 parking spaces, thus meeting the minimum required by the Code. 5. LANDSCAPING/IMPROVEMENTS Ordinance 4593 reduced the minimum amount of required landscaping along street frontages in the CO Zone from 15 feet to 10 feet. The applicant has proposed 20 feet of landscaping along the SW 16th Street and Raymond Avenue SW street frontages. Since the project is located within the Green River Valley, an additional two percent (2%) of natural landscaping shall be required for developed sites as per the Soil Conservation Service Environmental Mitigation Agreement. These areas should not be dispersed throughout a site, but should be aggregated in one portion of the property. Where possible, the required two percent landscaping for adjacent properties would be contiguous. The proposal is required to have a minimum natural landscaping of 19,515 square feet, and has provided approximately 60,000 square feet of natural landscaping, primarily along Springbrook Creek and within the creek setback area. The CO Zone also requires a pedestrian connection from a public entrance to the street unless the Hearing Examiner determines that the requirement would unduly endanger., the pedestrian. The applicant would need to provide striped crossings or another suitable type of pedestrian connection from each of the two proposed buildings to the sidewalks on SW 16th Street and Raymond Avenue SW.. This would need to be shown on a revised site plan that would be submitted and approved by the Development Services Division prior to the issuance of Building Permits. 6. ROOF-TOP EQUIPMENT The CO Zone requires that all operating equipment located on the roof of any building be enclosed so as to be shielded from view. The applicant would be required to meet this Code condition and to demonstrate to the satisfaction of the Development Services Division that it has been met prior to the issuance of a Building Permit. 7. REFUSE AND RECYCLABLES COLLECTION &STORAGE The CO Zone requires that all garbage, refuse or dumpsters contained within specified areas shall be screened, except for access points, by a sight-obscuring fence or landscaping or some combination thereof. The applicant's Landscape Plans indicate areas where dumpsters would be located. These areas would be enclosed with a 6-foot high fence with a gate serving as an access point. The proposal would comply with this requirement. C. MITIGATION OF IMPACTS TO SURROUNDING PROPERTIES AND USES; The project site is located adjacent to and east of Springbrook Creek and the Boeing Longacres site. Office development is located across SW 16th to the north, and across Raymond Avenue HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Hearing Examiner SW 16th STREET R&D TECHNICAL CENTER LUA-96-034, SA, SM, ECF PUBLIC HEARING DATE: May 14, 1996 Page 9 of 11 SW to the east. The vacant parcel to the south have been approved for light industrial/office uses. Proposed buildings would be setback from Springbrook Creek to retain natural vegetation and buffering. Minimum 800 foot setbacks from SW 16th Street and Raymond Avenue South would allow for minimum 20 foot wide landscaped buffers along street frontages. The applicant has reached agreement with the City for the accommodation of future proposed City projects on the site including the widening of Springbrook Creek and the extension of Oakesdale Avenue SW. An area in the northwest corner would not be developed with structures and would be reserved by the applicant for the eventual development of these City projects. By reserving this area, surrounding properties owners can predict how the City projects would impact their sites. D. MITIGATION OF IMPACTS OF THE PROPOSED SITE PLAN TO THE SITE; The proposal would result in the development of a 22.4 acre site. Two small Category 3 wetlands on the southwest portion of the site would be filled as allowed under City Code, a third large Category 3 wetland would also be filled and recreated in an off-site location. The applicant has applied for and received approval from the City to participate in the Wetlands Mitigation Bank for the creation of off-site wetlands. Raptor perching areas have been identified on this parcel as part of site studies for another project proposal. The applicant has proposed to install temporary raptor perch poles in affected areas, until such time that planted vegetation has established or matured to provide adequate perching habitat. The Site Plan would need to be revised to indicate the number and location of these perch poles. This would be a condition of approval and would need to occur prior to the issuance of Construction or Building Permits. The Landscape Plan identifies Platanus acerfolia (London Plane) trees for use in perimeter landscape beds. Staff has concerns about the selection of this tree type as the root system is invasive and can heave pavement when used in street right-of-ways. The applicant has agreed to find a suitable substitute street tree. E. CONSERVATION OF AREA-WIDE PROPERTY VALUES; The proposal would redevelop a partially developed site presently used as a distribution center for the Group Health Cooperative. Construction of the site would conserve and enhance property values by providing a project with office, research and development, manufacturing uses. Site improvements would include perimeter and interior site landscaping that would provide buffering for the two large buildings. The proposed development would be similar in scale and architectural character to existing Valley development and as such would be expected to conserve and enhance area-wide property values. F. SAFETY AND EFFICIENCY OF VEHICLE AND PEDESTRIAN CIRCULATION; The project would include three new access driveways along SW 16th Street, replacing the two existing curb cuts. Two new curb cuts would be installed along Raymond Avenue SW, and one existing curb cut would continue to access the site. Another existing curb cut would be eliminated on Raymond Ave SW. Internal site circulation would allow for access around all sides of the two proposed structures. Parking for 624 vehicles would be distributed in lots on the east, north and west sides of both structures. Limited additional parking would be provided adjacent to the south building facades.

However, the site plan lacks clear pedestrian connections between the two buildings and also from Building "A" to SW 16th Street, and from Building "B" to either SW 16th Street or Raymond Avenue SW. As a condition of approval staff will recommend that the applicant be required to provide pedestrian connections in the form of striped walkways or other suitable delineation to facilitate pedestrian safety. G. PROVISION OF ADEQUATE LIGHT AND AIR; The proposal would result in the construction of one new building and a large addition to an existing structure. The structures would be separated on the site by a distance of approximately 100 feet. Buildings would be set back from surrounding streets by a minimum of 80 feet. Lot coverage would be approximately 43%, and structures would be approximately 31 feet in height (depending on future tenant needs, the building height could increase by 6 feet for a total of 37 feet in height). Lighting would be provided in the parking lot during evening hours. Shielded lights have been proposed to minimize or eliminate spill over light to off-site properties. The development does not appeal to have any adverse impacts to the provision of light or air on or off of the site. Staff will recommend that the applicant submit a lighting plan to the Development Services Division for review and approval prior to the issuance of Building Permits. H. MITIGATION OF NOISE, ODORS AND OTHER HARMFUL OR UNHEALTHY CONDITIONS; Construction of the proposed project site would result in short term noise impacts during construction activity. Operation of the development would not be expected to produce odors or other harmful or unhealthy conditions. The development of these structures is speculative in nature, but the potential tenants being marketed for the site do not use toxic or hazardous materials. Any future tenant would need to adhere to all required codes in order to minimize any environmental health hazards, and to provide a plan to control such an event, if it occurred. AVAILABILITY OF PUBLIC SERVICES AND FACILITIES TO ACCOMMODATE THE PROPOSED USE;AND Public services are already available to serve the project site. The applicant would need to provide any Code-required connections or improvements, unless otherwise waived by the City. In addition, staff will recommend that the applicant provide additional on-site recreational opportunities for employees. This recreation should be in the form of active recreation (for example, a basketball hoop). J. PREVENTION OF NEIGHBORHOOD DETERIORATION AND BLIGHT. The proposal, including the architecture of the buildings and installation and maintenance of landscaped areas should prevent neighborhood deterioration and blight. Areas held in reserve for future widening of Springbrook Creek and the Oakesdale Avenue extension would need to be maintained by the applicant, owner or tenant of the development.

Spring Brook Creek actual location may not be within the Drainage District #1 legally described boundary. If not, Drainage District #1 may claim adverse possession of property. This has happened in the past. If true this could change the location from where the off-set to the Building is measured. The right-of-way near the Spring Brook Creek bridge abutment does not seem.to match what is on City's Oakesdale Avenue SW extension drawing. The bridge abutment should be shown and a tie-in at the existing Oakesdale intersection. A current title report needs to be provided and the developer's consultant needs to confirm the present location of Spring Brook Creek. 2. The City's Comprehensive Plan for Storm Drainage calls for widening of the Spring Brook Creek Channel which may have a major impact to the building set back. The City's Storm Drainage Division is working to determine what will be needed for the channel widening at this site. Coordination with the City's Storm Drainage Division will be needed. 3. , The detention pond and parking lot to the west of Building "A" is located in the alignment of the Oakesdale Avenue SW extension. The project needs to show an overlay from City drawings which shows the Oakesdale Ave SW extension. Agreements with the Transportation Division will need to be coordinated. 4. The preliminary drainage calculation may have to be revised after the above • comments have been resolved. 5. There is a surface water System Development Connection charge of $0.129 for new impervious surface area. This would best be calculated when the above comments have been addressed. The new impervious surface area may be impacted. 6. Drainage report to address King County Surface Water Manual Core and Special requirements. 7. Elevation Certificate will be require due to the flood plan impact. WASTE WATER (Sewer): 1. If the project produces fats, oils, or grease then an appropriate removal system will be required. 2. Side sewers to have a 2% grade to the right-of-way. A clean-out shall be located within five feet of the building and one clean-out every 100-feet. 3. Provide plan and profile. Show finish floor elevation and slopes of pipes. 4. Minimum pipe cover is two feet. 5. The System Development Connection charge is $0.078 per square of site. Calculation of the System Development Connection charge would best be done after resolution of storm drainage and transportation review comments which may have an impact on the area for calculating the charge. 6. Construction plans must comply with the City of Renton Drafting Standards. 7. If floor elevation is below 22-feet as shown than a back flow prevention device will be require on the sewer system. 96CM067 . ` 4 CITY OF RENTON City olwenton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION RE iIEWi NtEET REVIEWING DEPARTMENT: 1eVtt•w— Uia- COMMENTS DUE: MARCH 25 9 c2 ntvisI,pN APPLICATION NO: LUA-96-034,SA,V,SM,ECF DATE CIRCULATED: MARCH 19, 1996 APPLICANT: EDI LINARDIC(LDG ARCHITECTS) PROJECT MANAGER: JENNIFER TOTH HENNING PROJECT TITLE: R&D-SW 16TH TECHNICAL CENTER WORK ORDER NO: 78072 LOCATION: 801 SW 16TH STREET SITE AREA: 22.24 ACRES BUILDING AREA(gross): 85,000 SQ.FT.

I have reviewed your submittal information,and also the City of Renton staff report dated April 16, 1996. BACKGROUND: The proposed development project involves the construction of a 129,000 square foot new building and a 202,000 square foot addition to an existing structure on a partially developed 22-acre site at SW 16th Street and Raymond Avenue SW. The applicant,has obtained an Environmental Determination of Nonsignificance-Mitigated (DNSM), and has submitted for Site Plan Review and a Shoreline Substantial Development Permit. The subject property is bounded on the west side by Springbrook Creek. Based on a delineation of wetlands performed by Parametrix„Inc. there are three small wetlands on the site. These three wetlands were determined to be exempt from the Corps of Engineer's jurisdiction under Section 404 of the Clean Water Act. The total area of two of the three wetlands is under 5,000 square feet and therefore exempt from the City of Renton's Wetland Ordinance. The third wetland is a Category 3 wetland, approximately 16,700 square feet in size and is regulated under the City's Wetland Ordinance. Based on the size of the proposed development, it would be impossible to avoid the Category 3 wetland. Replacing the wetland elsewhere on-site would not be a desirable option as it would greatly reduce the size of the proposed development. The applicant has requested to participate in the City's wetland mitigation bank which is a .permitted option under Section 4-32-6 G. of the Wetland.. Ordinance. The applicant also requests an Administrative Waiver, as provided by Section 4-32=5.D.1.' This waiver is needed to allow a wetlands replacement ratio of 1:1 (Section 4-32-6.C.3 calls for a replacement ratio of 1.5:1), and to allow the wetland to be replaced after the subject wetlands have been filled (Section 4-32-6.C.5 states that the City may decrease the ratios for Category 3 emergent wetlands to 1.0 times the area, provided the applicant has successfully replaced the wetland prior to its filling). • 200 Mill Avenue South—Renton, Washington 98055 Group Health Site • Wetland Mitigation Administrative Decision 4/30/96 Page 2 FINDINGS: 1. The Category 3 wetland in question is located in the southern portion of the site where the applicant has proposed to develop storm water facilities and compensatory storage. 2. The Category 3 wetland was identified as a perched wetland on fill material. It appears that the wetland has limited biological and physical functions which could be more effectively replaced in a mitigation bank. DECISION: The request for Administrative approval to participate in a Cooperative Wetlands Mitigation Bank per section 4-32-6.G., and the request for Administrative Waiver, as provided by section 4-32-5.D., of section 4-32-6.C.3 to allow a wetlands replacement ratio of 1:1 rather than the required 1.5:1 replacement ratio, and of the requirement of section 4-32-6.C.5 in order to allow the wetland to be replaced after the subject wetland has been filled, are hereby granted subject to the following conditions: 1. There shall be compensation payment in the amount of$3.00 per square foot of replaced wetland for participation in the wetland mitigation bank prior to the issuance of a Building Permit. 2. There shall be a one year period from this approval where full or partial refunds could be made to the applicant if the City substantially alters the Wetland Management Ordinance in such a way that minimizes or deletes the need for compensation for filling of the subject wetland during this time period. • Sincerely, mgee(~,,_, Gregg Z. erman, Administrator Planning/Building/Public Works Department cc: Tom Lee, O'Keefe Development • Jim Hanson, Development Services Director - Jennifer Toth Henning, Project Manager Request for reconsideration must be filed in writing on or before 5:00 p.m., Tuesday, May 14 1996.

This request shall set forth the specific ambiguities or errors discovered by such appellant, and the Administrator may, after review of the record,take further action as he deems proper.

On behalf of the purchaser of the property, we request participation in a cooperative wetlands mitigation bank project with the City of Renton, as provided by Code 432-6G. We also request an Administrative Waiver (as provided by Code Section 6-32-6.G) to allow a wetland replacement ratio of 1 to 1 instead of 1 to 1.5 and to allow wetland mitigation to occur following the filing of wetlands on the property. Parametrix identified and delineated three small wetlands on the site. These three areas were determined to be exempt from Corps of Engineer jurisdiction under Section 404 of the Clean Water Act (see attached letter). Two of these areas were determined to be less than 5,000 square feet in size, and they are thus exempt from the City of Renton Wetland Management Ordinance. The remaining wetland is a Category 3 wetland and about 16,700 square feet in size. The Category 3 wetland cannot be avoided by the proposed wharehouse facilities because it is located near Raymond Avenue, interfering with site access and internal circulation. Because the wetland has recently developed on poorly drained fill material, it provides limited biological and physical functions typically attributed to wetlands. These functions can be effectively replaced and enhanced in a mitigation bank where they can be integrated into a more complex wetland system. Please do not hesitate to call me (822-8880) or Tom Lee (236-6200) if you have any questions or require additional information. Sincerely, PARAMETRIX INC. • im Kelley.

The Committee, on April 16, 1996, decided that your project may be issued a threshold Determination of Non-Significance-Mitigated with the following conditions: See enclosed Mitigation Measures document. Because the Environmental Review Committee imposed specific mitigation measures rather than issue a Determination of Significance, there is a required 15 day comment period during which comments are solicited from various agencies, jurisdictions or individuals (including the applicant)who may have an interest in the Committee's decision. The required 14 day appeal period will run concurrently with the comment period. The comment/appeal period will end at 5:00 PM on May 07, 1996. • Following the end of the comment/appeal period, the City will finalize its Determination, unless comments received require a reevaluation. WAC 197-11-660 states that the responsibility for implementation measures may be imposed upon an applicant only to the extent attributable to the identified adverse impacts of the imposed action. Since an environmental impact statement has not been prepared for this project, any mitigation measure established by the ERC not directly attributable to an identified adverse impact is deemed to be voluntarily accepted by the applicant. Staff urges you to contact the various City representatives, as appropriate, (e.g., the Public Works Division) as soon as possible, to obtain more.information concerning specific mitigation elements recommended for this project, if you have specific questions. This information will assist you in planning for implementation of your project and will enable'you to exercise your appeal rights more fully, if you choose to do so. - Appeal procedures and mitigation measures imposed by the City of Renton's Environmental Review Committee are available at the Development Services Division, Third Floor, Municipal Building, Renton, Washington 98055. Phone: 235-2550. You should be prepared to make specific factual objections. A Public Hearing will be held by the Renton Hearing Examiner at his regular meeting in the Council Chambers on the second floor of City Hall, Renton, Washington, on May 14, 1996 at 9:00 AM to consider the Site Approval (SA). If the Environmental Determination is appealed, the appeal will be heard as part of this public hearing. If you have any questions or desire clarification of the above, please call me at 277-6186.

The buildings would be speculative, and no tenants have been identified by the applicant. Currently the site is used for warehouse, offices and medical laboratories. An existing metal building 4,200 square feet in size and approximately 8,000 square feet of the existing structure would be demolished to accommodate the proposal. Existing site development is concentrated in the northeast corner of the property and consists of a 93,000 square foot structure and associated parking lots. Proposed development would consist of an 202,000 sf addition to the existing structure (85,000 sf after demolition) resulting in a structure that is 287,000 sf, and a new 129,000 sf building. The addition would extend to the west and south, while the new building would be located on the western portion of the triangular-shaped parcel. Stormwater treatment and detention facilities would occupy the southern portion of the property. The total size of the Research and Development (R&D) facility would be 416,000 square feet. The new construction would feature concrete tilt-up walls and wood roofing. The building would step back on each facade. According to the City's Parking and Loading Ordinance, a minimum of 608 parking spaces and a maximum of 849 parking spaces would be required. A total of 618 parking spaces are proposed in parking lots located on the perimeter of the buildings. Three new access driveways would be provided along SW 16th Street, replacing the two existing curb cuts. Two new curb cuts would be installed along Raymond.Avenue SW, and one existing_curb cut would continue to,access the site.: Another existing curb cut would be eliminated on Raymond Ave SW. In order to develop the site as proposed, the applicant would need-to import up to 75,000 cubic yards of material. The fill would be used for preloading and to elevate-the building above the flood plain. Once the building pad has settled, the remaining material would be distributed by means of spreading, across the site. The applicant proposed to begin preloading in early summer if approvals have been obtained. The project is located in the Valley Planning Area and is required to include an additional two percent (2%) of the site area as natural landscaping. The site proposal includes approximately three times the,required area as natural landscaping. Three wetland areas have been identified on the site. However, the US Army Corps of Engineers has determined that no jurisdictional wetlands occur on the property (letter of April 4, 1996). Two of the wetlands (A and B) are less than 5,000 square feet in size and are hydrologically isolated, and therefore would not be regulated by the City's Wetland Ordinance. Wetland C is 16,718 square feet in size and meets the criteria as a Category 3 wetland under the City's Wetland Ordinance. Wetland C is located west of Raymond Avenue SW and generally on the southern portion of the site. A minimum 25-foot buffer is required around wetlands of this size. Since the applicant proposes to fill the wetland, other suitable restoration or compensation at a ratio of 1.5 times the area altered is required. The applicant is coordinating with the City as part of a separate effort to participate in the City's Wetlands Mitigation Bank, or, as an alternative, move the wetland to a location elsewhere on the site that would allow the development as envisioned. The south and west boundaries of the project site are located adjacent to Springbrook Creek. The bank of Springbrook Creek has a steep slope of approximately 1:1. Vegetation consists of dense brush. The City's Shoreline Master Program states that commercial buildings should be located no closer than 50 feet to the water's edge (unless reduced by the Hearing Examiner for good reason for SITEERC.DOC City of Renton PB/PW Departmer__• Environmental Determination&.=_..Lristralive Land Use Action R&D Southwest 16th Tech Center LUA-96-034, SA, SM,ECF REPORT AND DECISION OF APRIL 16,1996 Page 3 of 9 those structures that allow public access to and along the water's edge). Industrial structures should be setback 25 feet from the water's edge, as long as public access is provided to and along the water's edge. (Public access is interpreted by the State and City to include visual and physical access.) The proposed buildings would be setback a minimum of 50 feet from the Ordinary High Water Line (OHWL). No clearing, grading or other disturbance would occur within 25 feet of the mean high water mark for the creek. Since the project is within 200 feet of the creek, it is subject to requirements of the City's Shoreline Master Program and requires a Shoreline Substantial Development Permit. Another small stream, Rolling Hills Creek is located just south of the property boundary in a ditch about 10 feet deep. Portions of the project site (southern one-half) are located within the 100-year flood plain. The applicant has provided a compensatory flood storage plan as part of their submittal. The 100-Year Floodplain Compensation Plan indicated that 340,000 cubic feet of flood volume would be displaced by the project. Compensatory volume from the removal of material below elevation 16.0 in ponds and with parking lot ponding would allow for the storage of 345,000 cubic feet of water. Part Two: ENVIRONMENTAL REVIEW A. Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1) Earth Impacts: Construction and site preparation activities (import of up to 75,000 cubic yards of fill) could result in erosion and sedimentation. City Codes require the applicant provide a Construction Mitigation Plan and a Temporary Erosion and Sedimentation Control Plan (TESCP) prior to the issuance of a Construction Permit. Mitigation Measures: No further mitigation required. Policy Nexus: N/A 2) Air Impacts: Construction activity would result in increased levels of airborne particulate (especially dust) potentially impacting air quality in the area of the project site. Emissions from construction equipment would have a minor impact on local air quality.. Construction impacts would be short term in nature and would be regulated through best management practices of the required TESCP. Vehicular emission are regulated by the State of Washington. Mitigation Measures:-No further mitigation required. . Policy Nexus: N/A 3) Wetlands Impacts: Three wetlands have been identified on the subject parcel. Wetland A is a small depression occurring on fill and is 1,437 square feet in size. Wetland B is well-defined (up to 3 feet in depth) and occurs on fill material. The wetland covers 1,111 square feet. Wetland C occurs in a shall depression and covers 16,718 square feet. Wetland C is considered to meet the criteria for Category 3 wetlands and is regulated by the City's Wetlands Ordinance. Since Wetlands A and B SITEERC.DOC City of Renton P/B/PW Departmei _ Environmental Determination&'_ istrative Land Use Action R&D Southwest 16th Tech Center LUA-96-034, SA, SM,ECF REPORT AND DECISION OF APRIL 16,1996 Page 4 of 9 are hydrologically isolated and less than 5,000 square feet in size, they are exempt from requirements of the Wetland Ordinance and may be filled. The applicant is negotiating with the City in order to participate in the Wetlands Mitigation Bank to enable filling of the Wetland C to occur. The City has identified an area of sufficient size for wetland creation on the City-owned Wetlands Mitigation Bank site that is not subject to Army Corps of Engineers jurisdiction. As an option to participation in the wetlands bank, the applicant would relocate the wetland on-site with the required compensation areas and buffers. In any event, the applicant will need to provide the City with a final plan as to how they intend to mitigate for the filling of Wetland C. Since the final resolution could affect the way in which the site plan is configured, the wetland mitigation plan would need to be submitted and approved prior to the public hearing for Site Plan Review. Mitigation Measures: The applicant shall submit a final wetland management plan subject to the review and satisfaction of the Development Services Division for the filling of Wetland C on the project site. The final wetland mitigation plan must be submitted prior to the public hearing for Site Plan Review. Policy Nexus: SEPA Ordinance, Wetlands Ordinance 4) Fire Protection Impacts: The proposal would add new construction to the-City which would potentially impact the City's Fire Department. A Fire Mitigation Fee would apply to all new construction, less the area of demolished structures (as applicable). The fee has been estimated at a rate of$0.52 per square foot of new construction. For Building 'A"the fee is tentatively estimated at $67,080.00 (129,000 square feet X $0.52). For Building B"the fee is tentatively estimated to be $105,040.00 (202,000 square feet X$0.52). The Fire Mitigation Fee is payable at the time that the Building Permits are issued. Mitigation Measures: The applicant shall pay the appropriate Fire Mitigation Fee at a rate of $0.52 per square foot of new construction. (Credit may be given for area of demolished structures.) This fee is payable prior to the issuance of the Building Permit. Policy Nexus: Fire Mitigation Fee Resolution and adopting Ordinance; SEPA Ordinance. 5) Transportation --New Traffic Impacts The proposal would result in increased vehicular trips that would impact the City's road system. The applicant has not identified a tenant for the R & D building and has not estimated the total number of new trips that would be associated with the development. Staff is requiring a traffic report which shows the existing trip ends and new trip ends generated by the proposed project. The report must also address any impacts that the newly generated traffic volumes could have on SW 16th Street and any local intersections. Any new trips would be subject to the City's Traffic Mitigation Fee. This fee is assessed at a rate of $75 per each new average daily trip. The fee would be applied to the project based on estimates from the ITE manual, unless the applicant's traffic study yields different results and the City concurs with the report. Credit may be given based on the number of existing trips generated by the existing use that would be eliminated under the proposal. The Traffic Mitigation Fee is payable prior to the issuance of a Building Permit. Mitigation Measures: The applicant shall pay the applicable Traffic Mitigation Fee at a rate of $75 per each new average daily trip attributable to the project. Credit may be given for existing trips on the site that would be eliminated under the proposal. The fee will be estimated based on the ITE Manual and the applicant's traffic study, and is payable prior to the issuance of a Building Permit. SITEERC.DOC City of Renton PB/PW Departme!.

This would require approximately 3,750 truck trips. Although this would be a substantial number of truck trips, it should not have a significant impact on the area roadways as they are already designed for heavy truck traffic in the surrounding office and industrial area. If the truck trips were to occur during the AM or PM peak traffic flows, they would impact the flow of traffic. No construction-related traffic should be permitted during pre-loading activities except between 8:30 am and 3:30 pm. Mitigation Measures: The applicant shall limit construction traffic on the adjacent arterials during pre-loading activities to the hours between 8:30 am and 3:30 pm. Policy Nexus: SEPA Ordinance 7) 100-Year Flood Plain Impacts: The project is located within the 100-year flood plain. Compensatory storage is required for flood waters displaced by proposed project development. The applicant has provided a compensatory storage plan indicating that 345,000 cubic yards of water could be accommodated in ponds and with parking lot ponding. This amount exceeds the amount (340,000 cubic yards) displaced by project development. Mitigation Measures:. None required beyond that proposed by the applicant Policy Nexus: N/A B. Recommendation Based on analysis of probable impacts from the proposal, staff recommend that the Responsible Officials make the following Environmental Determination: DETERMINATION OF X DETERMINATION OF NON-SIGNIFICANCE NON-SIGNIFICANCE-MITIGATED.

R&D Facility/SW 16th Technical Center(New) (Henning/6186) LUA-96-034,SA,SM,ECF The applicant proposes to develop a new one-story structure (Building A) and an addition to an existing structure (Building B) on a partially developed 22-acre site. Building A would be 129,000 sq. ft. in size, while Building B would result in the addition of 202,000 square feet. to an existing 85,000 sq. ft. building. A total of 618 parking spaces would serve the site. These would be speculative buildings, with office, and high-tech manufacturing uses anticipated. Three wetlands are present on the site. Three wetlands are present on the site. Two small wetlands are not regulated and would be filled. A third wetland (approximately 16,000 square feet) is subject to the requirements of the Wetlands Management Ordinance. The site is located adjacent to Springbrook Creek, although no development is proposed within 25 feet of the mean high water mark. The project requires Environmental Review, Site Plan Approval, and a Shoreline Substantial Development Permit. Location: 801 SW 16th Street. Chevron/McDonalds on Fourth (New) (Henning/6186) LUA-96-037,SA,V,ECF The applicant requests Environmental Review (ECF) for redevelopment of the subject property with a Chevron Gas Station and convenience store with a McDonald's quick-serve restaurant. Three new underground fuel storage tanks would also be installed. The proposal also requires Site Plan Review and is subject to a public hearing since the adjacent property to the south is zoned and designated for residential use. Location: 3209 NE 4th Street (at Monroe Ave NE). Arterial Commercial(CA) Zone Code Amendments (New) (Cohen/5578) LUA-96-044,ECF Code Amendment to allow bus, truck and recreational vehicle sales as a secondary use in the CA zone.

PLANNINGBUILDING/PUBLIC WORKS MEMORANDUM DATE: April 10, 1996 TO: Gregg Zimmerman FROM: Ron Olsen STAFF CONTACT: Ron Straka(X-5548)Q . Scott Woodbury(X-5547) SUBJECT: USE OF THE WETLAND MITIGATION BANKING PROJECT PRIOR TO ITS CONSTRUCTION As you had requested, we have evaluated whether there is sufficient area on the wetland mitigation banking sites to construct the wetland mitigation required for the SW 16th Street Technical Center Project (LUA-96-034). The two mitigation banking sites total 44.80 acres.- Site 1 is 30.97 acres consisting of 12.19 acres of uplands and 18.78 acres of wetlands. Site 2 is 13.93 acres and consists of 7.24 acres of upland and 6.69 acres of wetlands on fill. If all of the upland area on both sites is converted to wetland, then a total of 19.43 acres of wetlands would be created. Of this amount, at least 4.11 acres must be used to mitigate for'the Glacier Park impacts per the Wetland Mitigation Bank Agreement (King County Recording No. 9206241805) and 4.08 acres would need to be reserved to mitigate for City transportation projects. Assuming a 1:1 replacement ratio based on acreage alone and subtracting these prior obligations leaves a total maximum of 11.24 acres available for compensating wetland impacts from other projects. Attached is a copy of existing condition plans for Sites 1 and--2 with probable locations for constructing the Technical Center's wetland mitigation shown. It is our opinion that wetlands could be created in these areas without triggering any federal permits or state permits other than SEPA environmental review. There is, therefore, little risk of being denied the permits to construct the mitigation solely for the SW 16th Street Technical Center on the mitigation bank sites, as the authority to do so would lie with the City alone. We hope that this information is helpful. If you have any questions, please contact Ron Straka at X-5548 or Scott Woodbury at X-5547.

The waterfilled depressions on the site were created in dry land incidental to construction activity and therefore are not waters of the United States. Springbrook Creek and Rolling Hills Creek, which flow along the southwest and south property lines of the site, respectively, are waters of the U.S. below the ordinary high water mark. Both creeks are adjacent to and below the headwaters of the Green River. Excavation, mechanized vegetation removal, or placement of fill material below the ordinary high water marks of the two creeks would require a Department of the Army permit . Streams and creeks are dynamic ecosystems highly subject to change and Federal regulations are also subject to change. Therefore, this jurisdictional determination may be considered valid for only 5 years from the date of this letter, unless new information warrants revision of the delineation prior to this date. If you have any questions, please call Mr. Evan Lewis at telephone (206) 764-6908 . Sin erely, . ikei440-66,7 -- „Ige n R.

Mr. Lewis said a letter confirming this will be forth coming. This will allow us to pursue the wetland bank as an option; or if it is not an option, we would intend to move the wetlands to a more advantageous location on the site that would better suit both the redevelopment and the wetland.

The wetland areas on-site total about 0.44 acre (19,267 ft2). Two small streams are also present along the south and west boundaries of the site. Wetlands on the site may not be regulated by Section 404 of the Clean Water Act (Administered by the Army Corps of Engineers) because they have developed on fill. Two wetlands are exempt from the City of Renton wetland management standards due to their small size (<5,000 ft2) while one wetland (16,718 ft2) is a Category 3 wetland. METHODS On August 24, 1995, Parametrix staff conducted a wetland reconnaissance to identify and delineate wetlands and the ordinary high water mark (OHWM) of Spring Brook and Rolling Hills creeks. Wetlands were evaluated and delineated by Parametrix staff using the methodology outlined in the Wetland Delineation Manual (Environmental Laboratory 1987). The City of Renton, the Corps of Engineers, and Washington's Department of Ecology all require use of this manual and delineations were completed using the "routine" methodology, as identified in the 1987 Manual. Field data, including information on vegetation, soils, and hydrology, were collected and recorded on data sheets to document the characteristics of the project area (Appendix A). Wetland plants of the State of Washington (Reed 1988), as amended by the U.S. Army Corps of Engineers, Seattle District (Reed 1993) provided information on the indicator status of vegetation in the project area (Table 1). Scientific and common plant names used in this letter report are consistent with Hitchcock and Cronquist (1981) (Appendix B). Wetland communities identified and delineated within the project corridor were classified using the U.S. Fish and Wildlife Service Classification of Wetlands and Deepwater abitats of the United States (Cowardin et al. 1979).

Obligate Upland Plants UPL Plants that rarely (<1% of the time) occur in wetlands, but almost always(>99%of the time) occur in non-wetlands. Soils maps in the Soil Survey King County Area, Washington (Snyder et al. 1973) and the Hydric Soils of the United States (Soil Conservation Service 1991) provided information on soils. Soils in the project area were examined by digging a sample pit to a depth of at least 20 inches to observe soils and determine hydrologic conditions. The Munsell Color System (Kollmorgan Corporation 1994) was used to describe soil colors for low chroma and mottling, as these are indicators of wetland hydrology and hydric soils. Following the delineation and flagging of the wetlands and after determining the OHWMs of Spring Brook and Rolling Hills creeks, flag locations were mapped by Parametrix registered land surveyors. RESULTS UPLAND AREAS Most of the site, which was determined to be non-wetland, is a mosaic of forest, shrub, and herbaceous vegetation. The dominant tree in the forested areas is Populus trichocarpa,but there are a few scattered Alnus rubra. The understory in the forested areas is dominated by Rubus discolor and Rubus ursinus, and Solanum dulcamara, with Urtica dioica the dominant herb. The shrub areas are dominated by Rubus discolor, and the herbaceous clearings are dominated by Agrostis tenuis,Bromus inennis, Tanacetum vulgare,and Plantago lanceolata. Wetland Delineation- GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 2 Parametrix, Inc. • Soils on the site are mapped in the Soil Survey King County Area Washington (Snyder et al. 1973) as the non-hydric Urban land, with a significant amount of the area surrounding the project site also mapped as urban land. Urban land consists of soil that has been modified by the additions of fill material. Fill observed on-site ranges from about 3 ft to more than 12 ft thick. Fill on the site was a mix of extremely compact brown (10YR 4/3) gravelly sandy clay loam to a very loose olive brown (2.5Y 4/3) sandy loam. A small amount of waste material, mainly consisting of asphalt fragments, was found immediately adjacent to 84th Avenue South. In addition to the areas mapped as urban land, the other soil mapping units on the site include a small area of Woodinville silt loam and the Puget silty clay loam. The area mapped as Woodinville silt loam is located in the southeast corner of the site, and the Puget silty clay loam is associated with Spring Brook along the western project boundary. The Puget Series consists of poorly drained hydric soils that formed in alluvium, under sedges and grasses, in small depressions located in river valleys. The Woodinville Series are located on nearly level and gently undulating, poorly drained hydric soils that also formed on alluvium, under sedges and grass, adjacent to rivers and streams. To assist in the verification that fill material had been placed on the site, and to determine the approximate timing of the fill, available aerial photographs spanning a 24-year period (1965-1989) were reviewed (Table 2). The examination of these photographs (in stereo pairs, where possible) revealed that the site had been filled prior to 1965, with additional fill material added between 1965-1969. The review also revealed that the GHC Distribution Center was completed in 1978. Table 2. Aerial photographs reviewed to evaluate fill material at the Group Health Cooperative Distribution site'.

WETLAND AREAS Three wetland systems were identified and delineated on the fill material described above. The three wetlands included two shrub wetlands and a forested wetland. These wetlands are perched on compact fill material and thus may not be regulated as jurisdictional wetlands by the U.S. Army Corps of Engineers 1. Two small creeks, Spring Brook and Rolling Hills creeks occur on the west and south borders of the property, respectively. Because of the fill material, the two creeks are confined in U-shaped channels up to 10 ft deep below the fill surface. The wetlands identified and OHWMs of creeks are described below and identified on the survey map in Appendix C. I The Seattle District of the U.S. Army Corps of Engineers has recently excluded several wetlands from jurisdiction when it is clear they have developed on legally placed fill. Wetland Delineation - GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 4 Parametrix, Inc. Wetland A Conditions Wetland A is a small depression occurring on fill. The area covers 1,437 ft2 and is located west of 84th Avenue South and south of the GHC Distribution Center. Wetland vegetation consists of Salix scoulerana (FAC), Phalaris arundinacea (FACW), and Agrostis tenuis(FAC). More than 50 percent of the dominant species within the wetland has an indicator status of FAC and/or FACW (Appendix A; Sample D-1); therefore, this plant community meets the criteria established for a hydrophytic plant community. Soils in Wetland A are mapped as Urban land in the Soil Survey King County Area Washington (Snyder et al. 1973). As mentioned above, Urban land is soil that has been modified by disturbance of the natural layers with the additions of fill material several feet thick. Soils in the wetland are a compact grayish brown (2.5Y 5/2) gravelly sandy clay with dark, yellowish brown (10YR 4/6) mottles. Because of the low chroma in the matrix and the presence of mottles, this soil meets the technical criteria for hydric soil. During our site visit, soils were not saturated; however, there was evidence of seasonal ponding, including silt stains on leaves and water marks on shrubs. Because of the evidence of seasonal ponding in this area, wetland hydrology was assumed to occur during the growing season, and the wetland hydrologic criteria are thus met. The U.S. Fish and Wildlife Service classification system (Cowardin et al. 1979) classifies Wetland A as a palustrine scrub/shrub (PSS) wetland. The presence of hydrophytic vegetation and hydric soil conditions, as well as topographic changes, were used to delineate the wetland boundary. Adjacent Uplands The area surrounding Wetland A consists of landscaping on the north side, 84th Avenue South to the east, and a mix of native and introduced shrubs and herbs to the south and west. The dominant shrub in the area to the south and west is Rubus discolor(FACU), and herbs include Agropyron repens(FAC-), Dactylus glomerata(FACU), Bromus inermis(UPL), and Chrysanthemum leucanthemun (UPL). Less than 50 percent of the dominant species in these upland areas are assigned a wetland indicator status of FAC, FACW, and/or OBL (Appendix A, Sample D-2); therefore, this plant community does not meet the criteria established for a hydrophytic plant community. Soils adjacent to Wetland A are mapped as Urban land in the Soil Survey King County Area Washington (Snyder et al. 1973). Soil in the upland areas surrounding Wetland A, which appear to be fill,are a light olive brown (2.5Y 5/3) compact gravelly sandy loam. Because Wetland Delineation - GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 5 Parametrix, Inc. C of the high chroma in the matrix and the lack of mottles, this soil does not meet the technical criteria established for hydric soil. In addition to the soils described above, several piles of asphalt were also present in the vicinity of Wetland A. Wetland B Conditions Wetland B is a well-defined (up to 3 ft deep) depression occurring in fill material. The wetland covers 1,111 ft2. The wetland is located west of 84th Avenue South and south of Wetland A. The wetland is dominated by a shrub overstory of Salix scoulerana and Salix lasiandra (FACW+). Along the east side of the wetland, and at the base of the fill slope of 84th Avenue South, are several Populus trichocarpa(FAC). The herbaceous component is a mix of Phalaris arundinacea, Solanum dulcamara (FAC+), and Ranunculus repens (FACW). More than 50 percent of the dominant species within Wetland B have an indicator status of FAC and/or FACW (Appendix A; Sample C-1); therefore, this plant community meets the criteria established for a hydrophytic plant community. Soils in Wetland B, which consist of fill and are a dark gray (10YR 4/1) silty clay loam with strong brown (7.5YR 4/6) mottles. Because of the low chroma in the matrix and the presence of mottles, these soils meet the technical criteria for hydric soil. During our site visit, soils were not saturated; however, there was evidence of seasonal ponding, including silt stains on leaves and water marks on shrubs. Because of the evidence of seasonal ponding in this area, wetland hydrology was assumed to occur during the growing season. The U.S. Fish and Wildlife Service wetland classification system (Cowardin et al. 1979) classifies Wetland B as a palustrine scrub/shrub (PSS) wetland. Wetland B was delineated based on the presence of hydrophytic vegetation, hydric soil, and the well-defined topography of the depression. Adjacent Uplands The upland areas surrounding Wetland B consisted of 84th Avenue South to the east and a dense patch of Rubus discolor to the west. This dense patch of shade from the Rubus discolor prohibits the establishment of a significant herbaceous layer. Since the adjacent uplands are not dominated by any wetland plants, the plant community does not meet the criteria established for a hydrophytic plant community. Wetland Delineation- GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 6 Parametrix, Inc. Soils adjacent to Wetland B consist of fill material and are a brown 10YR 4/3) siltyclay ( loam and appeared to be fill material. Because of the high chroma in the matrix and the lack of mottles, this soil does not meet the technical criteria established for hydric soil. Wetland C Conditions Wetland C occurs in a shallow depression that covers 16,718 ft2. The wetland is located west of 84th Avenue South and Wetland B. The wetland'is forested, with an overstory dominated by Populus trichocarpa. A shrub layer is absent and the herbaceous layer includes Phalaris arundinacea, Ranunculus repens, and Solanum dulcamara. More than 50 percent of the dominant species within the wetland has a wetland indicator status of FAC and/or FACW (Appendix A; Sample #7); therefore, this plant community meets the criteria established for a hydrophytic plant community. Soils in Wetland C are mapped in the Soil Survey King County Area Washington (Snyder et al. 1973) as the hydric Woodinville silt loam (SCS 1991). The Woodinville series is made up of nearly level and gently undulating, poorly drained soils that formed under grass and sedges, in alluvium. Soils observed in Wetland C.have a 12-inch surface layer composed of • fill. This soil is a brown (10YR 4/3) .compact gravelly sandy clay over a grayish brown (10YR 5/2) sandy clay with yellowish brown (10YR 5/4) mottles. Because of the low chroma in the matrix and the presence of mottles directly below the surface layer, this soil meets the technical criteria for hydric soil. During the site visit, soils were not saturated; however, due to the hydrophytic plant community and presence of hydric soil conditions, it is likely wetland hydrology is present during the early growing season. The U.S. Fish and Wildlife Service wetland classification system (Cowardin et al. 1979) classifies Wetland C as a palustrine forested (PFO) wetland. The presence of hydric soil and the topographic changes defining the depression were used to delineate the wetland boundary. Adjacent Uplands Upland areas north of Wetland C consist of Rubus discolor,while the area south of Wetland C is dominated by herbaceous species, including Agrostis tenuis (FAC), Bromus inermis (UPL), Anthoxoanthum ordoratum (FACU), and Plantago lanceolata (FAC+). Of the dominant species (Bromus inermis and Anthoxanthum ordoratum) in these upland areas, less than 50 percent is adapted to wetlands (Appendix A; Sample #6); therefore, this plant community does not meet the criteria established for a hydrophytic plant community. Wetland Delineation - GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 7 Parametrix, Inc. ' C i Soils adjacent to Wetland C are composed of fill. The upland soils present in this area are fill soils. They are a brown (10YR 4/3) sandy loam. Because of the high chroma and the lack of mottles, this soil does not meet the technical criteria established for hydric soil. Spring Brook Creek Conditions Parametrix staff also identified and flagged the OHWM of Spring Brook Creek. Riparian vegetation within the OHWM of Spring Brook Creek includes areas with an overstory dominated by Alnus rubra (FAC) and Populus trichocarpa. The dominant shrub in these areas is Rubus discolor, other shrubs include Corpus stolonifera (FACW), and Spiraea douglasii (FACW). Herbaceous species in this riparian area are Phalaris arundinacea, Scirpus microcarpus (OBL), Typha latifolia (OBL), and Equisetum hyemale (FACW). Greater than 50 percent of the dominant vegetation within the OHWM and wetland fringe has an indicator status of FAC, FACW, and/or OBL (Appendix 1; Sample B-1); therefore, this plant community meets the criteria for a hydrophytic plant community. Soils along the Spring Brook Creek are mapped in the Soil Survey King County Area Washington (Snyder et al. 1973) as the non-hydric Puyallup fine sandy loam (SCS 1991). The Puyallup series is made up of well-drained soils that formed in alluvium, adjacent to streams in the river valleys under grass, hardwoods, and conifers. Soils within the OHWM of Spring Brook Creek are fill and/or dredged material. They are a dark grayish brown (2.5 • Y 4/2) to olive brown (2.5Y 4/3) sandy clay loam with dark yellowish brown (10YR 4/6) mottles. Because of this low chroma and the presence of mottles, this soil meets the technical criteria for hydric soil. The U.S. Fish and Wildlife Service (Cowardin et al. 1979) wetland classification system classifies Spring Brook Creek as a riverine, lower perennial, unconsolidated bottom (R2UB) wetland system. The wetland edge and OHWM of the creek were delineated based on the presence of hydrophitic vegetation and hydrologic indicators. Adjacent Uplands The area above the OHWM of Spring Brook Creek has an overstory dominated by Populus trichocarpa, with Rubus discolor the dominant shrub. Herbaceous species include Phalaris arundinacea, Equisetum hyemale, and Tanacetum vulgare (UPL). Greater than 50 percent of the dominant vegetation above the OHWM and adjacent to Spring Brook Creek is adapted to wetlands; for this reason, the plant community meets the criteria for a hydrophytic plant community. Soils east of Spring Brook Creek are mapped as Urban land in the Soil Survey King County Area Washington (Snyder et al. 1973). Soils in the upland area are fill and either a brown Wetland Delineation - GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 8 Parametrix, Inc. (10YR 4/3) silty clay loam or an olive brown (2.5Y 4/3) sandy loam. Because of the high chroma in the matrix and the lack of mottles, these soils do not meet the technical criteria established for hydric soil. Rolling Hills Creek Conditions Rolling Hills Creek, a small stream that flows into Spring Brook Creek on the site, was examined. The creek is located just south of the property boundary in a ditch about 10 ft deep, and the OHWM was flagged. Vegetation within the OHWM includes Alnus rubra, Rubus discolor,and Phalaris arundinacea. Because greater than 50 percent of the dominant vegetation within the OHWM of Rolling Hills Creek is adapted to wetlands (Appendix 1; Sample A-1), this plant community meets the criteria for a hydrophytic plant community. Soils along the un-named stream are mapped in the Soil Survey King County Area Washington (Snyder et al. 1973), as the hydric Woodinville silt loam (SCS 1991); however, the soils appeared to be composed of dredge material from Rolling Hills Creek. Soils within the OHWM are a dark grayish brown (10YR 4/2) sandy clay loam with strong brown (7.5YR 4/6) mottles. Because of the low chroma in the matrix and the presence of mottles, this soil meets the technical criteria for hydric soil. Using the U.S. Fish and Wildlife Service (Cowardin et al. 1979) classification system, this un-named stream is a riverine, lower perennial, unconsolidated bottom (R2UB) wetland system. Adjacent Uplands The area above the OHWM of Rolling Hills Creek has an overstory dominated by Alnus rubra, with a shrub layer dominated by Rubus discolor and Cytisus scoparius (UPL). Herbaceous species consist of Phalaris arundinacea and Tanacetum vulgare (UPL). The dominant vegetation above the OHWM of Rolling Hills Creek (Appendix A; Sample A-2) is adapted to wetlands; this plant community, therefore, meets the criteria for a hydrophytic plant community. Soils north of the un-named stream are mapped in the Soil Survey King County Area Washington (Snyder et al. 1973) as the hydric Woodinville silt loam (SCS 1991). Soils were found to consist of fill and dredge material that was a dark grey (10YR 4/1) silty clay loam with yellowish brown (10YR 5/6) mottles. Because of the low chroma in the matrix and the presence of mottles, these soils meet the technical criteria established for hydric soil. While the upland area adjacent to Rolling Hills Creek has a hydrophytic plant community and contains soils with hydric morphology, topography and field observations suggest Wetland Delineation- GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 9 Parametrix, Inc. wetland hydrology is not present. The area adjacent to the creek is at least ten ft above the OHWM of the creek and it is unlikely this area floods or becomes saturated. The soils adjacent to the creek appear to have been a hydric soil placed in the area during dredge/fill operations; therefore, we did not identify this area as wetland. Wetland Delineation- GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 10 Parametrix, Inc. REGULATORY REQUIREMENTS CITY OF RENTON Ordinance No. 4346, Chapter 32 Wetland Management (City of Renton 1992) was used to evaluate and categorize wetlands on the GHC Distribution Center site. Wetland A and Wetland B are both hydrologically isolated wetlands formed on compacted fill material and are less than 5,000 ft2, therefore, these wetlands are not regulated under the City of Renton Ordinance. Wetland C is also a hydrologically isolated wetland that formed on compact fill material; however, since it is greater than 5,000 ft2, it meets the criteria of a Category 3 wetland. The City of Renton requires a 25-ft standard buffer for all Category 3 wetlands. The standard buffer widths for wetlands can be either increased or decreased (but not to less than 25 ft) by the City's Department Administrator. Buffer widths are generally •increased in unique situations, such as when endangered species are present, or when a larger buffer is necessary to protect a wetland functions or values. Wetlands on the Group Health Cooperative Distribution site do not contain endangered species, and since the wetlands do not provide high functional value, a larger buffer requirement is unlikely. Spring Brook Creek is regulated under the City of Renton's Shoreline Master Plan (City of Renton 1983). The portion of Spring Brook Creek within the project site is designated as an Urban environment. The Urban environment is defined as an area of high-intensity land use that includes residential, commercial, and industrial development. The Master Plan allows for the commercial and industrial development adjacent to shorelines designated as Urban environments. Commercial building must be located no closer than 50 ft to the water's edge; however, the Land Use Hearing Examiner may reduce this requirement for projects that allow public access to and along the water's edge. Industrial structures must be set back 25 ft from the water's edge, as long as they provide reasonable public access to and along the water's edge, or a 50-ft set back may be required. Rolling Hills Creek is also a regulated shoreline under the Shoreline's Master Program (SMP) (City of Renton 1983). The minimum setback would be 25 ft from the water's edge of Rolling Hills Creek for an industrial structure and 50 ft for a commercial building, as long as public access is provided to and along the water's edge. FEDERAL The U.S. Army Corps of Engineers is responsible for determining the jurisdictional status of all wetlands and special aquatic environments. This process includes confirmation of a wetland/upland boundary determination and the regulatory status of the wetland or special aquatic environment (i.e. above the headwaters, isolated, or adjacent), and the federal regulatory requirements for activities that may affect jurisdictional wetlands. Because the Wetland Delineation- GHC Renton Site January 19, 1996 Commercial Real Estate (55-2947-01) 11 Parametrix, Inc. wetland systems delineated on the site have developed on compact fill, they may not be regulated by the Corps as jurisdictional wetlands. RECOMMENDATIONS Parametrix, Inc. recommends that a wetland boundary verification and jurisdictional determination be submitted to the Army U.S. Corps of Engineers. This will allow the Commercial Real Estate Company to further evaluate the requirements of federal and local permits that affect the development potential of the site.

Development Services EIS REVIEW COMMENTS DEVELOPMENT SERVICES R & D Technical Center / SW 16th St. March 27, 1996 By Clinton Morgan TRANSPORTATION: 1. A traffic report will be needed which shows the existing trip ends and new trip ends generated by the proposed project. If significant, the report needs to indicate what impacts the new generated traffic volume will have on SW 16th Street and any local intersections. 2. There is a Transportation fee for new trips generated at $75 per trip. 3. Curb, gutters, sidewalks and street lighting will be required on SW 16th Street. A street lighting plan is required per City Standards and to extend the full length of the property frontage to the roadway. The open drainage ditch fronting on SW 16th Street would need to be tight line. Note: The City has a road improvement project for SW 16th Street that the above improvements will need to be coordinated with. Roadway grades and elevations need to coincide. 4. Construction drawings for street lighting and each utility drawings are to be on individual sheets. 5. Driveways to SW 16th Street to be kept to a minimum. 6. The Detention pond and parking lot to the west of Building "A" is located in the alignment of the Oakesdale Ave SW extension. The project needs to show an overlay from City drawings which shows the Oakesdale Ave SW extension. t4ofe Coordination with the City's Transportation plans will be necessary. A second route alternative would go through the south end of building "A". 7. The right-of-way near the Spring Brook Creek bridge abutment does not seem to match what is on City's Oakesdale Ave, SW extension drawing. The bridge abutment should be shown and tied at the existing Oakesdale intersection. 96CM068 City canton Department of Planning/Building/Pub __corks ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET • REVIEWING DEPARTMENT —ttun r--I- 1_ COMMENTS DUE: MARCH 25, 1996 APPLICATION NO: LUA-96-034,SA,V,SM,ECF DATE CIRCULATED: MARCH 19, 1996 APPLICANT: EDI LINARDIC(LDG ARCHITECTS) PROJECT MANAGER: JENNIFER �IENNING PROJECT TITLE: R&D-SW 16TH TECHNICAL CENTER _ WORK ORDER NO: 78072 ��,�L,Hil®Oty LOCATION: 801 SW 16TH STREET 1996 SITE AREA 22.24 ACRES BUILDING AREA(gross): 8 e'0 SQ.FT.

Spring Brook Creek actual location may not be within the Drainage District #1 legally described boundary. If not, Drainage District #1 may claim adverse possession of property. This has happened in the past. If true this could change the location from where the off-set to the Building is measured. The right-of-way near the Spring Brook Creek bridge abutment does not seem to match what is on City's Oakesdale Avenue SW extension drawing. The bridge abutment should be shown and a tie-in at the existing Oakesdale intersection. A current title report needs to be provided and the developer's consultant needs to confirm the present location of Spring Brook Creek. 2. The City's Comprehensive Plan for Storm Drainage calls for widening of the Spring Brook Creek Channel which may have a major impact to the building set back. The City's Storm Drainage Division is working to determine what will be needed for the channel widening at this site. Coordination with the City's Storm Drainage Division will be needed. 3. The detention pond and parking lot to the west of Building "A" is located in the alignment of the Oakesdale Avenue SW extension. The project needs to show an overlay from City drawings which shows the Oakesdale Ave SW extension. Agreements with the Transportation Division will need to be coordinated. 4. The preliminary drainage calculation may have to be revised after the above comments have been resolved. 5. There is a surface water System Development Connection charge of $0.129 for new impervious surface area. This would best be calculated when the above comments have been addressed. The new impervious surface area may be impacted. 6. Drainage report to address King County Surface Water Manual Core and Special requirements. 7. Elevation Certificate will be require due to the flood plan impact. WASTE WATER (Sewer): 1. If the project produces fats, oils, or grease then an appropriate removal system will be required. 2. Side sewers to have a 2% grade to the right-of-way. A clean-out shall be located within five feet of the building and one clean-out every 100-feet. 3. Provide plan and profile. Show finish floor elevation and slopes of pipes. 4. Minimum pipe cover is two feet. 5. The System Development Connection charge is $0.078 per square of site. Calculation of the System Development Connection charge would best be done after resolution of storm drainage and transportation review comments which may have an impact on the area for calculating the charge. 6. Construction plans must comply with the City of Renton Drafting Standards. 7. If floor elevation is below 22-feet as shown than a back flow prevention device will be require on the sewer system. 96CM067 - CITY OF RENTON City a:.rltore Department of Planning/Building/Public Works ; 6q.EIVED ENVIRONMENTAL & DEVELOPMENT APPLICATION REWARE2145 §6tEET REVIEWING DEPARTMENT: P A 1 J U _ �li COMMENTS DUE: MARCH 25 §4 DIVISION APPLICATION NO: LUA-96-034,SA,V,SM,ECF DATE CIRCULATED: MARCH 19, 1996 APPLICANT: EDI LINARDIC(LDG ARCHITECTS) PROJECT MANAGER: JENNIFER TOTH HENNING PROJECT TITLE: R&D-SW 16TH TECHNICAL CENTER WORK ORDER NO: 78072 LOCATION: 801 SW 16TH STREET SITE AREA: 22.24 ACRES BUILDING AREA(gross): 85,000 SQ.FT.

FOR THE PROPOSED SOUTHWEST 16TH TECH CENTER . R& D.SOUTHWEST 16TH.TECH CENTER FACILITY This.proposed project.is located at the southwest corner of S.W. 1.6th Street and Raymond Avenue S.W. in Renton. The existing property is partially developed and current use is warehouse, office, and medical.lab. The existing topography of the site is flat: ' ' . The project involves the construction of a new one-story building.totaling 129,000 sq. ft. and an addition of 202,000 sq. ft. to an existing building for a total of 416,000 sq. ft. with 6,08 parking stalls. The buildings will be used for office, high-tech manufacturing and warehousing. New storm water system, landscaping and asphalt parking areas will be constructed for the proposed project. The buildings will be constructed with concrete tilt-up walls with.insulated tinted glass and wood roofing. The buildings will be designed as spec buildings since no tenants have been secured at this time. The required approvals and permits for this project include site plan/SEPA review approval, variance and building permit. The property line to the south and to the west are bounded by Springbrook Creek. The bank of Springbrook Creek'has a steep slope of approximately 1 to.1. Vegetation consists of dense brush'. No - work is anticipated within 25 feet of.the.mean high-water mark. • II ' yvk 4 0° ® e\�o . • CONSTRUCTION MITIGATION PLAN FOR THE PROPOSED SOUTHWEST 16TH TECH CENTER Ft& D SOUTHWEST 16TH TECH CENTER FACILITY The proposed construction would start immediately after acquiring the,structural fill permit. Anticipated start date would be May 1, 1996. The fill should take approximately one month to place, baring any unforeseen settlement problems. The construction of the building will follow the fill and the anticipated start date would be July 1, 1996. The project should take approximately six months to construct, baring any unforeseen weather problems. The construction hours will be between 7:00 a.m. and 5:00 p.m. with weekend work as required to finish the project. The northerly portion of the site is developed while the southerly portion of the sites is covered with field grass, trees and is flat. Approximately 75,000 cubic yards of import will be delivered to this site for preload and sub base for parking. The haul route has not yet been selected, but will be provided for ' your approval prior to construction. Measures to minimize dust and mud are shown on the TESC drawings. The use of"quiet" equipment and limiting the work to the above stated hours will reduce noise impact. As a whole, the project will not create any additional impact to the surrounding environment. REC FIVED aP, 1 5 1.996 DEVECLIc..4;i8;.1:1, • VARIANCE REQUEST SOUTHWEST 16TH TECH CENTER This a request for a variance from Section 4-31-16D.3.b of the Zoning Code for the development of a 416,000 square foot R&D facility consisting of two single story buildings. Section 4-31-16D.3.b of the Zoning Code requires that buildings be setback not more that 40 feet from the property lines. The site is presently partially developed. There is a building of 93,000 square feet located along the north portion of the site. The building is setback from the north property line approximately 90 feet and 115 feet from the easterly property line. Thus,the present development does not comply with the Zoning Code building setback requirements. The present Zoning Code building requirement presents a hardship to the proposed development. The required building setback would create a project that would not be aesthetically pleasing since the building facade,which is over 800 feet long,would be setback only 40 feet from the property line.This is not enough to provide necessary landscaping and visual separation for both pedestrian and vehicle traffic. Present setbacks of between 80 to 100 feet is more appropriate.The required setback also creates hardship to adequately distribute the necessary parking for this project since the occupants would have to travel much greater distances to get from the parking area to building entrances. It is my understanding that this section of the Zoning Code is in the process of being amended by the Planning Commission and that the City Council is in favor of approving this amendment to the Zoning Code. The amendment would delete the requirement for the maximum building setback from the property lines. This request for the variance will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity since the proposed variance would actually enhanced the project and the adjacent properties. Since the required building setbacks are also in process of being amended by the city,the present setback would create a hardship for this project,since all new developments would not be restricted by the present building setbacks and would be able to develop projects that have better parking layouts and have better curb appeal.

The scope of work for this project is in general conformance with the American Society of Testing and Materials (ASTM) Method E 1527 - 94 "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process." 2.3 Previous Environmental/Geotechnical Investigations ATC reviewed the following reports which were provided to ATC by Group Health Cooperative: • Asbestos Survey - Distribution and Support Services Facility - Group Health Cooperative, Pickering Environmental Consultants, Inc., September 27, 1991 • Phase Two Environmental Site Assessment of Group Health DSSF, Pickering Environmental Consultants, Inc., April 1992 • Corrective Action Plan for Group Health DSSF, Pickering Environmental Consultants, Inc., September 1992 Details of these reports are discussed in other sections of this report. • ATC ENVIRONMENTAL INC. 2 PROJECT NO.80022.1601 PHASE I ENVIRONMENTAL SITE ASSESSMENT GROUP HEALTH COOPERATIVE DISTRIBUTION AND SUPPORT SERVICES FACILITY RENTON, WASHINGTON 3.0 SITE DESCRIPTION/SITE RECONNAISSANCE 3.1 Location and Legal Description • The project area is located in the Puget Sound region of western Washington and is part of the Seattle-Tacoma-Everett metropolitan area. The.project area is located within the City of Renton, King County, Washington. The project area address is 801 SW 16th Street, Renton, Washington. The project area consists of a single one-story concrete tilt-up building and two smaller maintenance/storage buildings situated on a roughly square-shaped lot. The lot is approximately 22.6 acres in area. 3.2 Site and Vicinity Characteristics 3.2.1 Site Improvements The project area is currently developed with three buildings and associated parking and landscaped areas. The main building is a concrete tilt-up building built in 1977 and consisting of 93,312 square feet. The second building is a two-story metal-sided building built in 1979 and consisting of 8,160 square feet. The third building is a one-story metal-sided building built in 1986 and consisting of 800 square feet. These project area developments comprise the northeastern third of the project area. The remainder of the project area is vacant, • undeveloped and mostly wooded. 3.2.2 Current Uses of the Property The project area is currently being used as a warehouse, distribution, and support services facility. The support services include purchasing, pharmacy specialty services, computer services, optical manufacturing, and laboratory services. The facility maintenance shop is located in the smallest of the project area buildings. The metal-sided two story building is used as storage. As indicated previously, two thirds of the project area is vacant and unused. 3.2.3 Current Uses of Adjoining Properties The surrounding areas are predominantly industrial, commercial, and undeveloped open space. The project area fronts on SW 16th Street on the north and is bounded by Raymond Avenue SW on the east. Springbrook Creek borders the west and southwest sides of the project area. North of the project area, across SW 16th Street, are several commercial developments and open space. From east to west these properties are The Austin Co., a wooded lot, and Loneacres Industrial Park. The Austin Co. is a office building and yard for an engineering and planning firm. Loneacres Industrial Park is a small industrial park with various tenants. Holmes Electric Co. is located northwest, across the intersection of SW 16th Street and Raymond Avenue SW. The Holmes Electric Co. site is an office and yard for an electrical contractor. East of the project area, across Raymond Avenue SW, is a preschool and daycare center. Also east of the project area is an office building complex surrounded by a large paved parking area. ATC ENVIRONMENTAL.INC. 3 PROJECT NO.800221601 . . . rPHASE I ENVIRONMENTAL SITE ASSESSMENT GROUP HEALTH COOPERATIVE DISTRIBUTION AND SUPPORT SERVICES FACILITY • RENTON, WASHINGTON West of the project area, across Springbrook Creek, is a Boeing office building complex. Southwest and south of the project area is open space consisting of grassy fields, wooded areas, and wetlands. 3.3 Hazardous Materials 3.3.1 Storage Tanks and Containers . Two underground storage tanks (UST's) were formerly present in the project area. Both tanks were removed in August, 1991. The first tank was a 6,000 gallon leaded gasoline UST located on the east side of the main building. This tank was used to fuel vehicles. No release from the tank was confirmed during tank removal. The second tank was a 250 gallon leaded gasoline UST located between the main building and the two-story storage building. This tank was used to fuel an emergency power generator. A release was confirmed during tank removal. With the discovery of the release, further investigation was conducted by Pickering Environmental Consultants, Inc in late 1991. This investigation involved soil sampling and the installation and sampling of eleven (11) groundwater monitoring wells. A remediation system was installed by Pickering in mid-1993. The system consists of nine (9) vapor extraction wells for a soil vapor extraction system and one (1) groundwater recovery well for a pump and treat system. The soil vapors are apparently vented untreated to the atmosphere under Puget Sound Air Pollution Control Agency (PSAPCA) permit. The pump and treat system pumps groundwater from the recovery well through an oil/water separator, air stripper, and then to the Metro sanitary sewer system. The discharge to the Metro system is permitted by Metro Discharge Authorization No. 430. The remediation system has apparently been in continuous operation since mid-1993. However, there is no evidence that there has been any monitoring or sampling to estimate the quantity of contaminants removed or to determine the the overall success of the system. It was indicated by Jim Douma of Group Health that the monitoring wells had been sampled in April, 1995. The analytical results of this sampling are presented in the report Groundwater Sampling - DSSF Site - for Group Health Cooperative, Pickering Environmental Consultants, Inc., May 24, 1995. Portions of the Pickering report provided to ATC by Group Health are included in the Appendix of this report. The following table presents these results as well as the MTCA Method A Cleanup Levels for groundwater.

The tank was observed to have a secondary containment. No spills or leaks were observed associated with the AGST. Hazardous materials are stored throughout the project area primarily in the Medical Laboratory, Maintenance Shop, Lens Laboratory,.Pharmacy Specialty Services, and in the warehouse area. There were no spills, leaks, or stains observed with any of the stored chemicals. All hazardous materials observed appeared to be stored properly and were in generally good condition. Material Safety Data Sheets (MSDS) were compiled for these materials in three-ring binders located in each department of the project area. Several drums of hazardous waste were located outside on the south side of the main building. The waste was indicated to be unusable laboratory chemicals which had been lab- ' packed and prepared for transport by Burlington Environmental. The drums appeared to be : intact with proper hazardous waste labeling indicating an accumulation start date of April 4, 1995. 3.3.2. Polychlorinated Biphenyls (PCB's) One pad mounted transformer is located on the north side of the project area building. A pole mounted transformer is located on the north perimeter of the project area along SW 16th t..: Street. A switch gear cabinet is located in the northwest corner of the project area along SW 16th Street. All three of these pieces of equipment are owned by Puget Power. In a telephone interview on May 3, 1995, Mr. Jeff Briggs of Puget Power indicated that the pad-mounted transformer and switch gear were manufactured as non-PCB. The.pole-mounted transformer has not been tested and must then be considered as PCB contaminated electrical equipment F,d according to federal regulations. It was indicated by Gary Betis, Maintenance Engineer, that the entire project area was relamped with assistance from Puget Power. All PCB ballasts were indicated to have been replaced with non PCB solid state ballasts. However, based on the construction date of the project area it is possible that ballasts containing PCBs may still be present. Labeling should be checked each time ballasts are replaced. 3.3.3 Asbestos-containing Materials ATC observed suspect asbestos-containing materials in the project area including resilient sheet flooring, carpet mastic, acoustic ceiling panels, sink undercoat material, and wallboard and associated joint compound. An asbestos survey was conducted in the project area by Pickering Environmental Consultants, Inc. (reference Asbestos Survey - Distribution and Support Services Facility - Group Health Cooperative, Pickering Environmental Consultants, Inc., September 27, 1991). Only select resilient sheet flooring in the Pharmacy Warehouse, Tape Lab, and Room 107 was identified as asbestos-containing. Select flooring material, drywall, 2 X 4 ceiling panel, pipe fitting, and cove base mastic were found to be non-asbestos. All suspect asbestos-containing materials observed in the project area were found to be in good condition and not damaged in such a manner that would pose a hazard of generating airborne asbestos fibers.

RENTON, WASHINGTON 3.3.4 Waste Generation and Disposal The project area generates several waste streams including biomedical waste, low-level radioactive waste, as well as normal municipal solid waste and recyclables. The project area is a registered as a small quantity generator of hazardous waste. However, there does not appear to be a regular hazardous waste stream. There appears to be only irregular generation of hazardous waste occurring when certain chemicals used on-site are no longer needed and must be disposed of properly. As indicated previously, several drums of hazardous waste were located outside on the south side of the main building awaiting transport to a hazardous waste treatment/storage/disposal facility. Biomedical waste is generated in the project area as a result of the laboratory activities conducted on-site. The biomedical waste is stored in plastic bins labeled as "biohazard". Approximately 40 to 60 plastic bins are generated per week. The biomedical waste is picked up weekly by Stericycle of Washington, Woodinville, Washington. Low-level radioactive (radioisotope) waste in the form of iodine 125 and cobalt 57 is generated in the Medical Laboratory as part of certain analytical procedures. The waste is stored in 55-gallon drums. The waste is handled by Allied Technology Group and disposed of at the Hanford Reservation. Other waste generated in.the project area consists of nonhazardous municipal solid waste and recyclable materials. A trash dumpster is present along the east side of the project area in a brick-walled enclosure. 3.4 Other Conditions of Concern 4 3.4.1 Lead-based Paint Lead-based paint of the type that would typically be applied on project area surfaces was banned in 1978. Therefore, there is the potential for the presence of lead-based paint in the project area. 3.4.2 Radon Western Washington is considered,by the Washington State Health Department to be an area of low risk with respect to radon. The majority of the project area is above grade with no basement or crawlspace. The presence of structures below grade increases the potential for radon accumulation. 3.4.3 City of Renton Monitoring Well ATC observed a single groundwater monitoring well located in the wooded area on the western edge of the property near Springbrook Creek. Jim Douma of Group Health indicated that the well was installed and is owned by the City of Renton as part of their Oakesdale Avenue expansion project. The well is part of an easement granting the City of Renton permission to test the soils and groundwater. ATC spoke with Bob Mahn of the City of Renton. According to Mr. Mahn, the monitoring well is owned by the City of Renton, and was installed as part of the Oakesdale Corridor Expansion Project. The monitoring well is used to monitor groundwater levels. A draft report regarding the well installation is being reviewed by the City of Renton and will be available to the public in approximately five weeks. ATC ENVIRONMENTAL INC. 6 PROJECT NO.80022.1601 PHASE I ENVIRONMENTAL SITE ASSESSMENT GROUP HEALTH COOPERATIVE DISTRIBUTION AND SUPPORT SERVICES FACILITY ' RENTON, WASHINGTON 4.0 ENVIRONMENTAL SETTING 4.1 Regional Physiographic Conditions The project area is located in the Puget Sound Basin which lies between the Cascade Range to the east and the Olympic Mountains to the west. The landscape configuration of the Puget Sound Basin is a consequence of multiple Pleistocene glaciations resulting in a series of north-trending elongated ridges, or drift uplands, separated by deep troughs, the latter now occupied by marine waters, fresh-water lakes, or underfit streams. Holocene modification of the glaciated landscape is manifest in the development of sea cliffs, formation of cuspate forelands, erosion of the uplands by small streams, and major landscape modifications by man. Deposits of the most recent (Vashon) glaciation, which ended 13.5 thousand years ago in the Puget Sound area, consists of a mappable drift sequence of lacustrine deposits, advance outwash, till, and recessional outwash that collectively dominate the surface and shallow subsurface geology. Older glacial and nonglacial materials, mostly in the subsurface, are less well defined. Source: Galster and Laprade, Geology of Seattle, Washington, Bulletin of the Association of Engineering Geologists, August, 1991. The project area is located in a north trending flat-bottomed river valley drained principally by the Green River and more locally by Springbrook Creek, both of which flow northward. The project area is found at an elevation of approximately 20 feet above sea level which varies little over the project area and valley bottom. . Drift uplands surrounding the project area include the Des Moines Drift Upland to the west, the Covington Drift Upland to the east, and the Skyway Upland to the north. These upland areas crest at 300 to 400 feet above sea level. Source: USGS topographic map (metric), "Renton, Washington", 7.5 X 15 minute, 1983. 4.2 Soil/Geologic Conditions In general, the project area is underlain by Recent alluvium composed mostly of clayey silt and fine sand, locally peaty. The alluvium may be as much as 30 to 40 feet thick beneath the project area. Source: Geologic Map of the Renton Quadrangle - King County, Washington, USGS Quadrangle Map GQ-405. 4.3 Hydrogeologic Conditions Based on investigations conducted in the project area in response to the leaking UST, it appears that groundwater is approximately 10 feet below grade. Groundwater flow direction has been determined to be towards the south based on Pickerings April, 1992 report (reference Phase Two Environmental Site Assessment of Group Health DSSF, Pickering Environmental Consultants, Inc., April 1992). It should be noted that groundwater depth and flow direction may vary over time in response to season, precipitation, and other factors. 4.4 Assumptions/Opinion on Contaminant Mobility - Site Vulnerability There do not appear to be any significant off-site sources of contamination which could impact the project area. The groundwater gradients in the relatively flat-bottomed valley are assumed to be very gradual. Therefore, any potential off-site contaminants are not likely to disperse very widely over time.

The photographs were reviewed at the University of Washington, Suzzallo Library Map Room, Seattle, Washington. The photograph dates ranged from 1961 to 1989. The following are descriptions and interpretations from the historical aerial photograph review. 1961 The project area is mostly vacant and undeveloped. It appears as a grass covered field with four large widely separated trees. One house with an outbuilding appears at the center north of the project area along SW 16th Street. SW 16th Street is in place. Longacres racetrack is present to the west across Springbrook Creek. To the north are small agricultural fields and scattered houses and outbuildings. To the east and south are open fields and woodlands. 1965 The project area appears unchanged except that the house and outbuilding are now gone. The Austin Co. building appears to be under construction to the north. Interstate 405 is present further north. There are no other significant changes apparent in the project area and surrounding areas. 1970 There are no significant changes apparent in the project area and surrounding areas. 1985 The project area and surrounding areas are developed as today. 1989 There are no significant changes apparent in the project area and surrounding areas. 6.2 Building Department Records City of Renton, Building Department ATC reviewed Building Department files regarding the project area.

ATC ENVIRONMENTAL INC. 15 PROJECT NO.80022.1601 PHASE I ENVIRONMENTAL SITE ASSESSMENT GROUP HEALTH COOPERATIVE DISTRIBUTION AND SUPPORT SERVICES FACILITY • RENTON, WASHINGTON 7.0 RESULTS OF INVESTIGATION • 7.1 Findings, Conclusions, and Recommendations Project Area LUST Remediation The project area currently has a remediation system in place and in operation which is designed to clean up contamination from a former leaking 250 gallon leaded gasoline UST. The tank was located between the main building and the two-story storage building. The system consists of nine (9) vapor extraction wells for a soil vapor extraction system and one (1) groundwater recovery well for a pump and treat system. The soil vapors are apparently vented untreated to the atmosphere under Puget Sound Air Pollution Control Agency (PSAPCA) permit. The pump and treat system pumps groundwater from the recovery well • through an oil/water separator, air stripper, and then to the Metro sanitary sewer system. The discharge to the Metro system is permitted by Metro Discharge Authorization No. 430. The remediation system has apparently been in continuous operation since mid-1993. Four on- site monitoring wells were recently resampled. (ref. Pickering Environmental Consultants, Inc. report, May 24, 1995.) Three of the wells indicated diminishing contaminant levels. However, the analytical results for two of these wells were still well above MICA Method A Cleanup Levels. One of the four wells revealed an increase in contaminant levels. Based on the recent analytical results from four on-site monitoring wells, it appears that there has been some decreasing levels of contamination in the groundwater. Two of the wells sampled, BH 2 and BH 6, are still well above the MICA Method A Cleanup Level. Based on the rate of contaminant decrease, it may be several years before contaminant levels are reduced below cleanup levels as the system is currently operated. Contaminant levels have increased in well BH 11. ATC recommends that the current remediation system be evaluated further and possibly reconfigured and redesigned to increase cleanup efficiency and reduce the length of time which the system will need to operate. Additionally, ATC recommends that sampling of groundwater be conducted on a more frequent basis (i.e. quarterly) to better track the remediation system's efficiency. Furthermore, ATC recommends limited soil sampling to determine if the soil vapor extraction system has been effective in cleaning up soil contamination. Asbestos-Containing Materials ATC observed suspect asbestos-containing materials in the project area including resilient sheet flooring, carpet mastic, acoustic ceiling panels, sink undercoat material, and wallboard and associated joint compound. Additionally asbestos containing resilient sheet flooring has been confirmed in selected areas of the project area. All suspect and confirmed asbestos- containing materials observed in the project area were observed to be in good condition and not damaged in such a manner that would pose a hazard of generating airborne asbestos fibers. ATC recommends sampling any suspect asbestos-containing materials prior to remodeling, renovation, or demolition activities which may occur in the project area.

The site, which is roughly triangular in shape, is located immediately south of SW 16th St and on the west side of the Raymond Ave SW right-of-way, as shown on the Plot Plan, Plate 1. A previous soils investigation has been performed by our office for a tract of land which included the present site. The results of this investigation were summarized in a report to the Metro Industrial District dated August 10, 1961. In the late summer of 1963, approxi- mately 2 ft of compacted granular fill was placed on this site. Our office provided inspection and testing of fill placement; the results were given to the District in a report dated October 8, 1963. A consul- tation concerning site development of this property was summarized in two letters to The Austin Company dated April 12 and April 22, 1974. SCOPE The purposes of this investigation are to explore the subsurface soil and groundwater conditions at the site, and to provide engineering recommendations for foundation support and site developmenZ;;,rspe�' , fically, our work includes the following: ro Ak 901 C1 y OF RLNTON -1- 'Dames $ MOORE 1. Design criteria for shallow foundations, including maximum allowable soil pressures for footing design, minimum footing widths, and minimum depth of footings. 2. Estimates of the magnitude of settlement for foundations designed as recommended. 3. Criteria for support of all floor slabs. 4. Estimates of floor slab settlement. 5. Recommendations for a surcharge program to minimize post- construction building settlement. 6. Recommendations concerning construction procedures, including site preparation, criteria for fill placement and compaction, • and for footing excavations. DESIGN CONSIDERATIONS We understand that the proposed development will include several buildings. The largest building will consist of a warehouse, storage, and service complex with the floor at truck-loading height. Floor loads in this structure will be variable; maximum storage loads in the central warehouse and receiving area have been estimated at 500 lb per sq ft. Lesser loadings are. anticipated in the peripheral storage and service areas. Expansion areas have been delineated on the north, south, and west sides of the warehouse complex. Other structures will include two 2-story office buildings in the northern portion of the site and a vehicle maintenance shop located south of the warehouse complex. Floor grade in these buildings will be at or slightly above finish yard grade. Anticipated floor loads in these buildings are not known. No infor- mation is presently available relative to structural loads in any of the -2- oAMES a MOORE t buildings. For analytical purposes, a maximum column load of 100 kips has been assumed. Final yard grade has not been established at this time; however, some amount of structural fill placement is anticipated in order to establish drainage across the site. Paved parking areas are planned in the north portion of the site between the two office buildings and to the west of the westernmost office building. Additional parking is to be provided south of the warehouse complex, adjacent to the proposed maintenance shop. The westernmost portion of the site will remain undeveloped at the present time. SITE CONDITIONS SURFACE CONDITIONS The site lies on the generally level terrain of the Green River' floodplain. The western boundary of the site is coincident with the alignment of an improved drainage channel which flows roughly from the' southeast to the northwest. The existing site grade was established by the placement of several feet of fill during 1963. The installation of this fill was observed and approved by our office. Some indications of earlier fill placement were noted during our current explorations. The horizontal and vertical extent of the earlier fill could not be deter- mined; however, it appeared to be limited to areas within the eastern • portion of the site. Elevations across the site vary generally from Elevation 20 in the southern portion to Elevation 23 along the northern property line, and Elevation 24 in the westernmost portion of the site. Isolated areas in the westernmost portion are at Elevation 26. Most of the proposed building areas lie at approximately Elevation 22. These -3- OAMES a MOORE . • elevations are based on U.S. Engineers Datum. At the present time the ground surface is covered with a moderate growth of grass and weeds, with occasional clusters of saplings to heights of less than 10 ft. Surface drainage at the site is relatively poor in its present condition, with localized areas of surface ponding during periods of rainfall. SUBSURFACE CONDITIONS • Subsurface conditions at the site were explored by drilling five borings at the locations shown on the Plot Plan. A detailed description of the fieldwork is presented in the Appendix, along with the logs of the borings. The results of our laboratory tests and a description of the testing procedures are also presented in the Appendix. The loca- tions of two borings performed in conjunction with our previous inves- tigation at this site are also shown on the Plot Plan. The surface soils across the site consist of fill. A thin layer of topsoil has developed, generally less than 2 in. thick. The fill on the eastern portion of the site consists of gray silty fine sand having some gravel. The remainder of the site is covered with a brown, slightly silty sand having a relatively uniform gradation. The fill soils are generally on the order of 2 and 3 ft thick, with up to 5 ft in localized areas. At the time of our explorations, the upper 6 to 12 in. of fill was in a loose, saturated condition. The remainder of the fill was dense. Two distinct native soil zones were noted during our field explo- rations; an upper zone consisting of relatively soft or loose deposits and a lower zone made up of dense sand and gravel. The total thickness of the upper soil zone and surface fill is on the order of 22 to 24 ft, -4- DAMES 8 MOORE .i . extending approximately to Elevation 0. The composition of the upper materials consists of soft to medium-stiff silts and clayey silts, and medium-dense slightly silty fine sands. In general, the finer- grained soils are found in the upper portion of this soil zone, grading to sands toward the bottom. The material in the upper soil zone has a greater proportion of sand in the western and southwestern portions of the site, in the vicinity of Borings 4 and 5. In the central building area the upper zone is primarily composed i . of the silt and clayey silt. The soils which lie just beneath the fill appear to be desiccated, resulting in a relatively stiff or dense condition within the upper 2 to 3 ft in comparison with the softer underlying soils. In general, the upper soil deposit is compressible and subject to settlement with the application of loads; however, the degree of compressibility varies for a given area, depending upon the relative proportion of silts and sands. No significant amount of highly compressible organic material such as peat was found in any of our borings; however, during our previous investigation, several swampy areas were noted just east of the site. Boring 2, which was placed at a location where an old meander scar might possibly encroach upon the site, encountered no evidence of organic soils. Although it is possible that some swampy areas may exist within the site, these areas would be isolated and limited in extent. The lower soil zone, which was encountered in our borings roughly • below Elevation 0, consists of dense silty sandy gravel with layers of sand. All of the borings were terminated in this competent stratum. Our current field explorations were conducted during a period of heavy rainfall; consequently most of the ground surface was covered with -5- DAMES 8 IAOORE standing water, making it difficult to establish the true groundwater level in the borings. A piezometer installed in Boring 5 indicated a water level at Elevation 16. Our laboratory tests indicated that the soils are saturated below this level. The water level should fluctuate somewhat with seasonal changes. Since our field explorations were performed at the start of the rainy season, we anticipate that the groundwater level may be somewhat higher during the winter months. CONCLUSIONS AND RECOMMENDATIONS GENERAL The subsurface conditions in the upper soil zone show significant variation, both horizontally and vertically, across the site. This variation poses a definite potential for moderately large differential as well as total settlements within the building areas. In order to develop satisfactory support for the structures using shallow founda- tions, we recommend that all footings be underlain by at least 3 ft of compacted fill. The purpose of this fill pad is to distribute the loads imposed by the footings within the fill, thereby reducing the load intensity which is transmitted to the more compressible underlying native soils. Significant settlement will occur within the warehouse complex under the influence of new fill required to establish floor grade and the imposed floor loads. Consequently, we recommend that surcharge fill be placed in advance of construction to preinduce a large portion of this settlement. Depending on the construction schedule and the magni- tude of floor loads, surcharge of the office building and shop areas may not be required. -6- OAMES a MOORE {f/ i FOUNDATION SUPPORT We conclude that the buildings may be safely supported on shallow footings founded within fill which is placed over the existing native soils, provided that the footings are separated from the native material by a minimum of 3 ft of properly compacted fill. On the basis of our explorations we feel that the existing fill across the site can be included in the provision of this thickness of fill, as long as the upper portion is properly compacted and any loose or water-softened material is removed and replaced with compacted fill. If the thickness of fill which is placed in building areas during site grading is not sufficient to provide a total thickness of 3 ft, it will be necessary to overexcavate the existing material and replace it with compacted fill. This zone of overexcavation and replacement should extend a minimum , of 18 in. out from each side of the footings. Overexcavation will not be necessary to provide the minimum 3 ft of fill beneath the footings for interior footings in the warehouse complex which are founded at minimum depth within the dock-height fill. We recommend that engineering inspection of the footing excavations and backfilling be provided to determine that the work is carried out as intended. We recommend that all footings have a minimum width of at least 18 in. and be founded not less than 18 in. below the lowest adjacent grade. Footings constructed in the manner described above may be designed using a maximum soil bearing pressure of 2,500 lb per sq ft. This value is intended to apply to the total of all loads--dead, . live, and seismic, exclusive of the weight of footings and any backfill over the footings. We estimate that the settlement of footings under the assumed structural loads will generally be on the order of 1 to 171 in. -7- OAMES 8 WMOORE I • �I • Some portion of this settlement will occur during construction; under a typical construction schedule, we anticipate that postconstruction • settlements will be less than 1 in. AREAL SETTLEMENT AND SURCHARGE REQUIREMENTS Our analyses for the warehouse complex indicate that the combina- tion of the dock-height fill and the anticipated floor loads will cause significant compression in.the underlying soil layers, resulting in total settlements on the order of 4 to 6 in. in those areas where the underlying native soils are composed of compressible silts. Approxi- mately 2 to 3 in. of this settlement will result from the weight of the dock-height fill. The magnitude of the remaining settlement would depend upon the intensity of the actual long-term floor loads. To reduce postconstruction settlement of the warehouse complex, we • recommend the use of a surcharge fill program to induce the major - portion of this settlement prior to the start of construction. To account for the varying design floor loads within the complex, we recommend that the thickness of surcharge be varied. The required thickness of surcharge fill for a given area is dependent upon the anticipated floor load within the area. For planning purposes, 1 ft of surcharge fill should be provided for each 100 lb per sq ft of design floor load, with a minimum surcharge thickness of 2 ft. The required thickness of surcharge should be measured from the design finish floor grade. Where transitions are required from heavier to more lightly loaded areas, we recommend that the greater thickness of surcharge extend 10 ft beyond the limits of the heavier load. The crest of the surcharge fill should extend at least 10 ft beyond the perimeter of the • area to be more heavily loaded in order to provide the necessary con- finement and consolidation load. -8- DAMES O MOORE t. Based on our analyses, we estimate that 90 percent of the settle- , ment resulting from the surcharge fill will take place within 75 days after placement of the fill. Assuming that the surcharge program is satisfactorily completed, we estimate that postconstruction settlement of floor slabs would be on the order of 12 in. for a maximum floor load of 500 lb per sq ft. In areas where future expansion is being considered, we recommend that the surcharge extend at least 25 ft beyond the limits of initial construction. Otherwise, the placement of new surcharge adjacent to the completed structure would be expected to cause a significant amount of additional settlement of this structure. In the areas to the north and south of the warehouse, it may be more practical to extend the surcharge across the entire expansion area during the initial surcharge period. We understand that the 2-story office buildings and the maintenance shop will have ground floor slabs at approximately the same grade as the adjacent yard area. Our analyses indicate that surcharging may not be necessary for these areas if floor loads are small and some differ- ential settlement can be tolerated. If construction is delayed for a period of time after the placement of any site fill in the building areas, settlement of the structures will be generally limited to that which results from structural and long-term live loads. We anticipate that 90 percent of the total settlement caused by fill placement will occur within 75 days after the fill is completed. We estimate that the settlement of floor slabs resulting from structural and long-term storage loads of 200 psf will be on the order of 1 in. Differential settlement may result in footings moving downward as much as in. below adjacent floor slabs, depending on construction timing. Settlements of -9- OAMES & MOORE • § to 1 in. should be anticipated for utility lines at their points of entryinto the building. The settlement estimates given above assume that no soft or loosened materials exist at the present ground surface. If the magnitude of settlement given above is not tolerable, or if the existing ground surface is disrupted during construction, preloading should be provided for the office buildings and the maintenance shop in accordance with the recommendations given earlier in this section. *We recommend that a series of settlement markers be installed in all preloaded areas prior to placement of any fill to monitor the rate and magnitude of settlement during the placement of structural and. surcharge fill. The settlement markers, if read on at least a biweekly basis during and after surcharge completion, would greatly facilitate the determination of the earliest practical surcharge removal date. SITE PREPARATION AND FILL PLACEMENT As discussed previously, the site is presently covered with grass. and clusters of brush. The necessity to strip the sod mat and topsoil from the existing surface will depend on the thickness of fill which will be placed to achieve the desired site grade. If pavement or building subgrades lie within 12 in. of the existing surface, all sod and organic material should be removed from the surface. Stripping should not be carried out during the wet winter months. If it is necessary to initiate fill placement during the rainy season, site grades should be adjusted to insure that pavement and building area subgrades are at an elevation at least 12 in. higher than the existing grade. If stripping is not accomplished, the existing growth of grass and brush should be mowed as closely as possible to the ground and the clippings removed from the site. Heavy construction traffic should be • -10- OAMES 1S MOORE ` i .. closely observed to determine that the existing ground surface is not disturbed or softened, particularly if work is attempted during the wet season. If construction traffic causes a significant disruption of the surface, an initial lift of fill consisting of clean, coarse sand or sand and gravel should be placed across the site to protect this sur- face. If construction during wetter months is a possibility, we recom- mend that planning and cost estimates include an allowance for this protective blanket. We recommend that all permanent new fill placed in building or pavement areas consist of well-graded predominantly granular pit-run material. The maximum percentage of silt- and clay-sized fines should be governed by weather and site conditions at the time of placement. During rainy weather the material should contain no more than 5 percent by dry weight passing a No. 200 mesh sieve. This fill should be placed in lifts having a maximum loose thickness of 8 in. and compacted to at least 95 percent of the maximum dry density as determined by AASHO Compaction Test Procedure T-180. Placement of surcharge fill may commence as soon as the structural fill is completed. We recommend that the permanent compacted structural fill be carried at least 6 in. above the planned floor slab subgrade in • order to allow for settlement during the surcharge period. No com- paction criteria are required for the surcharge fill which will be later removed. If the surcharge material is to be later used as structural fill outside the building area, we recommend that it consist of granular material as described above. All backfilling for utility trenches and other excavations in building and pavement areas should be placed and compacted in accordance with the recommendations given above for structural fill placement. -11- GAMES e. MOORE FLOOR SLAB SUPPORT Floor slabs may be supported on compacted granular fill. We recommend that slabs be directly underlain by at least 4 in. of clean free-draining coarse sand or sand and gravel which would retard the capillary rise of any water into the subslab area. We further recommend that a vapor barrier be installed between the base of the slab and the supporting soils. Ii PAVEMENT DESIGN • Assuming that all loose or softened areas in the existing fill are repaired, that all pavements are underlain by at least 12 in. of granu- lar subgrade compacted as recommended previously, and that.no unusual traffic loadings will be experienced, we suggest that the following pavement design section be used: Thickness in Inches • Auto Parking Truck Traffic Paving Course Areas Areas Asphaltic Concrete 2:' 2" Crushed Rock Base Course 4" 6" ' C K.

The locations of two borings from a previous investigation are also shown on Plate 1. The borings drilled during this investigation ranged in depth from 2411 to 40 ft below the existing ground surface. Ground surface elevations at the boring locations were estimated from a topographic survey by Meriweather-Leachman, based on U.S.. Engineers Datum. The field explorations were continuously observed by one of our engineers who classified the soils encountered, kept a detailed log of the borings, and obtained soil samples for examination and testing in our laboratory. The boring logs are presented on Plates A-1 and A-2. The soils have been classified in accordance with the Unified Soil Classification System, which is described on Plate A-3. Relatively undisturbed soil samples were obtained from the borings using a Dames & Moore Type U Sampler, which was driven with a weight of 350 lb falling a distance of 18 in. The number of blows required to drive the sampler a distance of 12 in. into undisturbed soil is shown immediately above the sample notation on the log of the borings. The infiltration of surface water into the borings prevented the measurement of accurate groundwater levels in Borings 1 through 4. A piezometer was installed in Boring 5 to permit more accurate water level measurements after completion of the boring. An observation made after the completion of our exploration indicated a groundwater level at A-1 OL\ME.S a AAOORE Elevation +16. This water level will probably fluctuate with seasonal variations in rainfall. LABORATORY TESTS Laboratory tests were performed on representative soil samples to evaluate strength and consolidation characteristics of the various soils. Soil strengths were evaluated by performing direct shear tests in accordance with the procedures described on page A-3. The results of the direct shear tests are presented in tabular form on Plate A-4. Two consolidation tests were performed for use in our settlement analyses. The equipment and methods used for the consolidation tests are described on page A-4. The results of the tests are presented graphically on Plates A-5 and A-6. Moisture and density determinations were made in conjunction with each of the above tests and on other selected samples for correlation purposes. These data are presented on the test summary plates and on the boring logs adjacent to the sample notations.

A CONSTANT PRES- SURE, APPROPRIATE TO THE CONDITIONS OF THE PROBLEM FOR WHICH THE TEST IS BEING PER- FORMED, IS APPLIED NORMAL TO THE ENDS OF THE SAMPLE THROUGH POROUS STONES. A SHEARING 111 FAILURE OF THE SAMPLE IS CAUSED BY MOVING THE CENTER RING IN A DIRECTION PERPENDICULAR 11 TO THE AXIS OF THE SAMPLE. TRANSVERSE MOVEMENT OF THE OUTER RINGS IS PREVENTED. THE SHEARING FAILURE MAY BE ACCOMPLISHED BY APPLYING TO THE CENTER RING EITHER A CONSTANT RATE OF LOAD, A CONSTANT RATE OF DEFLECTION, OR INCREMENTS OF LOAD OR DE- 1 FLECTION. IN EACH CASE, THE SHEARING LOAD AND THE DEFLECTIONS IN BOTH THE AXIAL AND TRANSVERSE DIRECTIONS ARE RECORDED AND PLOTTED. THE SHEARING STRENGTH OF THE SOIL IS DETERMINED FROM THE RESULTING LOAD-DEFLECTION CURVES. FRICTION TESTS IN ORDER TO DETERMINE THE FRICTIONAL RESISTANCE BETWEEN SOIL AND THE SURFACES OF VARIOUS MATERIALS, THE CENTER RING OF SOIL IN THE DIRECT SHEAR TEST IS REPLACED BY A DISK OF THE MATERIAL TO BE TESTED. THE TEST IS THEN PERFORMED IN THE SAME MANNER AS THE DIRECT SHEAR TEST BY FORCING THE DISK OF MATERIAL FROM THE SOIL SURFACES. A-3 DAMES 8 MOORE :i 1• METHOD OF PERFORMING CONSOLIDATION TESTS CONSOLIDATION TESTS ARE PERFORMED TO EVALUATE THE VOLUME CHANGES OF SOILS SUBJECTED TO INCREASED LOADS.

II • II IN TESTING, THE SAMPLE IS RIGIDLY CONFINED LATERALLY DEAD LOAD-PNEUMATIC BY THE BRASS RING. AXIAL LOADS ARE TRANSMITTED TO THE CONSOLIDOMETER ENDS OF THE SAMPLE BY POROUS DISKS. THE DISKS ALLOW DRAINAGE OF THE LOADED SAMPLE. THE AXIAL COMPRESSION OR EXPANSION OF THE SAMPLE IS MEASURED BY A MICROMETER DIAL INDICATOR AT APPROPRIATE TIME INTERVALS AFTER EACH LOAD INCREMENT IS APPLIED. EACH LOAD IS ORDINARILY TWICE THE PRECEDING LOAD. THE IN- CREMENTS ARE SELECTED TO OBTAIN CONSOLIDATION DATA REPRESENTING THE FIELD LOADING CONDITIONS FOR WHICH THE TEST IS BEING PERFORMED. EACH LOAD INCREMENT IS ALLOWED TO ACT OVER AN INTERVAL OF TIME DEPENDENT ON THE TYPE AND EXTENT OF THE SOIL IN THE ch FIELD.
