Renton, WA 98055 Bryn Mawr System Improvements Conditional Use Permit File #LUA-97-195, CU-H, SM Work Hour Issues Via Facsimile Dear Ms. Kittrick: In reviewing Condition#4 on Page 6 of the Conditional Use Permit, we find an inconsistency with our contract and our many previous discussions with the City regarding work hours. Section 01014, Paragraph 1.05 A. of the Contract allows the Contractor to work 24 hours per day in the park to meet the schedule requirements. This provision was cleared with Parks and other City staff during our monthly coordination meetings. It is essential to be able to work 24 hours per day in the park to complete work in time for the Corps "205" work to begin. As the Permit Conditions are currently written, we must quit hauling at 3:30 p.m. We are hereby requesting 24 hour hauling be approved to and from the park to meet our schedule. A second work hour issue has arisen regarding the former Mindeman's restaurant site. Our Contractor has requested extended work hours be approved at the Microtunnel pit. Initially, we propose to work from 7:00 a.m. to 7:00 p.m., six days per week at this site. If the Contractor can demonstrate that the work can be done without disturbing residents, we would then extend to a 24 hour operation. We would work with your staff, the residents and the Contractor to assure that the work does not disturb the public. Please feel free to call me at 206-684-1306, to discuss these matters in more detail. As I will be on vacation the week of March 16, you may also wish to contact our Resident Engineer, Keven Sandquist at 206-689-5434. Very truly yours, Richard M. Andrews, P.E.

Minor grade adjustments will be completed by the USACE during the final project. • Other Incidental and Unanticipated Restoration Requirements: The King County/Boeing project may require other unanticipated restoration. King County should provide for full like kind restoration of these features: The County should anticipate this work and provide additional funding for it.

We anticipate issuing Notice to Proceed on March 16, 1998, and completing construction in the park by July 6, 1998. As you know,meeting the aggressive project schedule has been a challenge for us. We hope that by combining the King County and Boeing Contracts and expediting the work, we have helped the City of Renton in its effort to construct the Corps of Engineers "205" Project this summer. But, while we are happy to accelerate the project for a good cause, King County has assumed considerable risk in advertising the contract without permits. Permit,easement or mitigation conditions received after bid opening could result in costly change orders to King County and Boeing. This only serves to waste money that could be put to better use. For this reason, I am asking that the City of Renton expedite its review of the project. We request the City prepare a list of likely requirements that can be expected as a condition of construction. In order to incorporate this information by addendum,we need to receive it by January 29, 1998 at the latest. You may fax the information to me at 206-684-1945. • CLEAN WATER —A SOUND INVESTMENT • Gregg Zimmerman • January 23, 1998 Page 2 • Thank you for your consideration to this matter.

PUBLIC HEARING: After reviewing the Development Services Report,examining available information on file with the application,field checking the property and surrounding area;the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the February 3, 1998 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,February 3, 1998, at 9:00 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: Vicinity map application,proof of posting,proof of publication and other documentation pertinent to this request. Exhibit Nos.3- 15: Enlarged drawings of sewer line at various station points The hearing opened with a presentation of the staff report by MARK PYWELL,Project Manager,Development Services,City of Renton,200 Mill Avenue South,Renton,Washington 98055.. The applicant requests approval to upgrade an existing sewer line and in some places a relocation of the line. Basically the project consists of 6,000 linear feet of 24-inch sewer main. In some places the pipeline would be sleeved and that sleeve would be 36 inches in diameter. This would be mainly in the area where the project will cross the north end of the airport and in the vicinity of the Cedar River where it will tunnel underneath the river. King County will be working jointly with Boeing to install the sewer main that is under this permit,as well as Boeing's King Co.Department of Natura.___Jources Bryn Mawr System Improvements File No.: LUA-97-195,CU-H,SM February 16, 1998 Page 2 storm water transmission line that was approved under another permit. The pipes will be located adjacent to one another although in separate trenches, or at least separated from one another. Also going on in approximately the same time period is the Cedar River dredging project that is under a separate permit. The City and applicants are working to coordinate the movement of materials and trucks so that there is the least impact possible, as well as safety of operation of the airport and linear park. A conditional use permit is required in the P-1 zone in which this is located for a major sewer interceptor. This project is consistent with the Comprehensive Plan(CP)which asks to promote the collocation of new public and private utility distribution lines. This project will allow for the joint installation and location of both the Boeing project and the Metro project,therefore limiting the area that will be disturbed. Landscaping is one of the areas that will be impacted,not only by this project but also by subsequent projects. The landscaping that is disturbed at the conclusion of the projects will be replaced at an equivalent to the landscaping that exists or better. On June 15 the pedestrian trail will be closed from Williams Avenue down to the mouth of the Cedar River. From June 15 it is projected there will be too much construction activity going on along the trail for it to be operated safely. The project location is suited for the proposed use. Although there are some issues with the safety, especially the long run of the airport where it crosses under the runway,this is an appropriate location for it. Those issues can be addressed through the various construction methods that are being used. They will be tunneling under the runway so as not to disturb the surface of the runway. The applicant will need to submit a traffic control plan as part of their construction documents. This will need to address such issues as insuring that emergency vehicles can access not only the project site but areas around the project site as it cuts across, especially down the streets. The applicant will need to restore or participate in the restoration of any streets that are damaged during the construction of this project. Noise and glare would only be associated with construction of the project and in the areas that it will be going through. There are a number of existing utility lines that this project has accounted for and been designed around so that it will not disrupt any of the services that are now being provided. The existing system during peak flows does spill over into Lake Washington. This new line will allow Metro to handle peak flows and thus reduce the disturbance to the lake. Staff is recommending approval of the Bryn Mawr improvement project, subject to several conditions: (1)informational signage and advertising of the construction activities shall be placed 30 days prior to beginning construction and maintained throughout the life of the project; (2)weekly reports on the status and condition of the erosion control plan and recommendations for changes or revisions to the maintenance schedule shall be submitted to the project engineer or public works inspector; (3)final construction plan indicating the haul route and the haul hours shall be submitted prior to approval; (4)the public works inspector shall be included in any regular construction meetings for coordination; (5)road restoration standards for Riverside Drive shall be a minimum of 2 inches of Class A asphalt over 4 inches of Class E asphalt over 6 inches of crushed rock; (6)any damage or service interruption to fire service or hydrants shall be coordinated with their appropriate owner,utility or agency. Both the Boeing and the City of Renton fire departments shall be notified of any water/fire lines to be taken out of service for any period of time. Hydrants that are no longer in use will need to be bagged; (7)the applicant shall reach an agreement with the City of Renton Community Services Department and Development Services Division regarding the replacement of landscaping prior to the issuance of construction permits; (8)applicant shall obtain all required City easements for the proposed project King Co.Department of Natural 1:cbources Bryn Mawr System Improvements File No.: LUA-97-195,CU-H,SM February 16, 1998 Page 3 prior to the issuance of construction permits; (9)the applicant shall submit a foreign object control plan to the airport area to the satisfaction of the Development Services Division prior to the issuance of any construction permits; (10)a separate traffic control plan for the airport and park shall be submitted to the satisfaction of the Development Services Division prior to the issuance of any construction permits; (11)the existing pedestrian trail along the east side of the Cedar River shall be kept open from the start of the project until June 15,at which time it will be closed. The trail shall be maintained during this time with a minimum width of 6 feet if there is a detour. The trail will be of a hard surface suitable for the Americans with Disabilities Act and the City of Renton. Larry Ellington,King County Department of Natural Resources, 506 2nd Avenue,#708, Seattle,Washington 98104, applicant herein, stated that the intent of King County was to try and minimize the impacts to Cedar River Park by aggressively moving forward the schedule for its construction so that it would coincide with the Boeing interceptor construction needs as well as preceding the City and the Corps of Engineer's dredging of the Cedar River. There are still some easements that have not been concluded,but they have reached substantial agreement with the City of Renton airport and Cedar River Trail Park in terms of easement requirements and restoration. The County is currently working;to reach agreement with the ground lessee at the northwest corner of the airport so that they will consent to the easement grant by the City of Renton airport. Regarding alternate routing of this project,a variety of alternative alignments were reviewed,particularly the perimeter road. In addition to utility conflicts that are located there, it is simply much longer and more costly. The connection point into the east side interceptor would have been at a different location requiring additional easements and construction in other properties. Mr.Ellington explained that the beginning of the project is at the northwest corner on private property where the Bryn Mawr-Lakeridge Sewer districts bring local sewer flows and discharge those into an existing Metro line. The existing alignment then goes in a siphon, comes out into the lake, across the north end of the airport, and then down Cedar River Trail Park. The applicant proposes to stay on land with an additional and larger line which would then come under the airport. Once it reaches Cedar River Trail Park,that line then merges coincident with the existing line, largely inside an existing easement. So it is really a pipe replacement until it gets down to North 6th Street where there will be two pipes that parallel one another. The lake line will continue to operate to provide additional flow capacity. Beverly Franklin, 537 Williams Avenue North,Renton,Washington 98055,asked for clarification on the completion date for this project. Mr.Pywell responded that it was scheduled to be completed by the end of 1998. Ms.Franklin also inquired whether pile driving would be required and stated that originally there was a lot of property damage in north Renton from the prior project. She was informed that there will be no pile driving. There will be micro-tunneling underneath the airport and then open trench for the rest of the construction. Ms.Franklin stated her concerns regarding damage to the homes and whose responsibility it would be to repair or replace those damages. Mr.Ellington responded that King County would be responsible for any damages caused by construction. In response to her query regarding traffic on residential streets, she was informed that there would no truck traffic on residential streets where it would not normally go. Leslie Betlach,Parks Director, City of Renton,200 Mill Avenue South,Renton,Washington 98055, stated that the trail will not be closed at all during construction for this particular project which concerns the Boeing project and the King County project. There will be no vehicular access to the park,but there will be pedestrian access the entire time. The only time the trail is proposed to be closed is during the dredging project. That is because there will be a lot of heavy equipment in the river as well as levee construction. The trail will be closed for the duration of the dredging project,which is anticipated to start on June 15. King Co.Department of Natural tcbources Bryn Mawr System Improvements File No.: LUA-97-195,CU-H,SM February 16, 1998 Page 4 The Examiner asked if there would be an alternate route for bike riders. Ms.Betlach responded that there was not yet an alternate route at North 6th. There is a small section that will be a detour at North 6th,primarily the area where the Boeing project comes into the park and through the trail. At that location the trail will be re- routed in the park. The Examiner called for further testimony regarding this project. There was no one else wishing to speak,and no further comments from staff. The hearing closed at 9:45 a.m. FINDINGS,CONCLUSIONS &DECISION Having reviewed the record in this matter,the Examiner now makes and enters the following: FINDINGS: 1. The applicant,King County Department of Natural Resources,filed a request for approval of a Conditional Use permit for a Metro sewer utility installation. 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. King County assumed responsible official status for this project and issued a Declaration of Non- Significance(DNS)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The proposal is not limited to a specific parcel. The proposal is for installing a major sewer transmission line and therefore is located in a corridor approximately 6,000 linear feet. The corridor begins at Burnett Avenue North and North 6th Street,follows North Riverside Drive along the east side of the Cedar River, crosses under the river near Lake Washington,crosses west under Renton Municipal Airport and terminates north of the airport near Rainier Avenue North. 6. The line will cross properties owned by private owners and public entities. Permission from these various parties has been or will be attained for the section being constructed pursuant to this request. Another segment of the line outside of the City will require permission of the owner or a condemnation. The segment in the City will go forward as the County has the right to attain access to any segments outside of the City. 7. Large portions of the line will be within 200 feet of either the Cedar River or Lake Washington. Therefore,a Shoreline Management permit is required. This permit is not part of this review. 8. Large utility lines require approval of a Conditional Use Permit from the City. 9. The corridor will be crossing through various Zoning Districts including Public Use and the Light and Heavy Industrial Zones. Since the use is below grade and will not have any surface facilities, zoning categories do not actually apply to this development although,as noted, it does require a Conditional Use Permit. • King Co.Department of Natura:�....ources Bryn Mawr System Improvements File No.: LUA-97-195,CU-H,SM February 16, 1998 Page 5 li 10. Similarly,the line will pass through areas with different Comprehensive Plan designations. The Comprehensive Plan recognizes the need to provide utilities and larger transmission facilities to serve any development in the City and surrounding community,and therefore,no particular Comprehensive Plan designation such as Heavy or Light Industrial governs this proposal. 11. The actual proposal is to both upgrade and supplement the existing sewer main that connects the Bryn Mawr community northwest of the City with the Metro transmission line located near Burnett and 6th. The existing line is an older line that has proved insufficient to handle peak flows. When the line's capacity is exceeded,untreated sewage is released into Lake Washington creating unsanitary conditions. 12. The new line will parallel and/or replace the existing line and provide sufficient capacity to avoid overflow conditions. In other words,there will be two lines in some locations,and the existing line will be maintained,providing additional capacity. 13. Where the current line is located in Lake Washington,the applicant proposes that the line will be south of it. The new line will cross under the Cedar River and under the airport to avoid having to work in the harder conditions in the lake and under its surface. • 14. The applicant will be using a series of tunneling and trenching techniques to install the line. To avoid disrupting the river bed and the airport,tunneling will be used. In other areas trenching will generally be used. 15. There are a number of other projects proposed for the same or adjacent corridors. Boeing will be installing a new storm line, and the pity in conjunction with other agencies is proposing dredging the Cedar River and installing a flood control system. The various applicants propose attempting to coordinate the projects to avoid multiple disturbances to the roads, linear park and river environment. They also provide coordinating the restoration of the areas that are disturbed. 16. There is concern over noise and construction vibrations and the techniques that could disturb neighboring residences. The various'applicants would be responsible for any resulting damages. Although they might not be driving piles,there may be hydraulic equipment used to install sheeting. CONCLUSIONS: 1. The applicant for a Conditional Use Permit must demonstrate that the use is in the public interest,will not impair the health, safety or welfare of the general public and is in compliance with the criteria found in Section 4-31-36 (C)which provides in part that: a. The proposal generally conforms with the Comprehensive Plan; b. There is a general community need for the proposed use at the proposed location; c. There will be no undue impacts on adjacent property; d. The proposed use is compatible in scale with the adjacent residential uses, if any; e. Parking,unless otherwise permitted,will not occur in the required yards; f. Traffic and pedestrian circulation will be safe and adequate for the proposed project; - d King Co.Department of Natural K�.ources Bryn Mawr System Improvements File No.: LUA-97-195,CU-H,SM February 16, 1998 Page 6 g. Noise, light and glare will not cause an adverse affect on neighboring property; ' I h. Landscaping shall be sufficient to buffer the use from rights-of-way and neighboring property where appropriate; and i. Adequate public services are available to serve the proposal. The requested conditional use appears justified. 2. Development depends on a range of urban services including sewer utilities. The Comprehensive Plan supports the development of appropriate infrastructure to support urban and suburban development including homes,business and various commercial and industrial uses. In addition, interagency cooperation requires that lines cross into and out of neighboring jurisdictions. The proposed line is compatible with these goals and objectives. 3. The current line is inadequate to handle heavy storm events or peak flows which force raw sewage into Lake Washington. That creates a potential health hazard as well as being unaesthetic. The resolution of this problem is definitely a community need. 4. The construction of the line will create a series of impacts on the surrounding community,but the line once installed will not create any untoward impacts. There will be digging,tunneling and shoring of the trench that will hold the line. There will also be traffic and heavy equipment which will probably create noise and dust. The development of the corridor also will interfere with the use of the Cedar River trail. As noted,there are a series of projects that are being coordinated in order to minimize the disruption and duration of the overall construction along the river and trail. 5. The sewer line will be underground and after construction will not be noticeable,and will not create noise, light or glare. It will have no parking demands and will not interfere with traffic. While construction is occurring,there will be some interference generally found in and around construction sites. 6. The trail,roads and other landscaping will be restored after all of the associated projects are concluded. Areas will be restored once no additional work will disturb those particular areas. The various project sponsors will be working together t i assure the full restoration of any disturbed areas. 7. The applicant will be responsible for assuring that all repairs to the airport, its runways,roads and landscaping are consistent with its safe operation including during construction and during the life of the line and after its abandonment, should that occur. 8. In conclusion,the proposal will have some interim impacts which will be unavoidable. There should be no lasting undue impacts on the City or neighborhoods affected. DECISION: The Conditional Use is approved subject to the following conditions: 1. The applicant shall be responsible for assuring that all repairs to the airport, its runways,roads and landscaping are consistent with its safe operation including during construction and during the life of the line and after its abandonment, should that occur. i 1 King Co.Department of Natural resources Bryn Mawr System Improvements File No.: LUA-97-195,CU-H,SM February 16, 1998 Page 7 2. Informational signage and advertising on the construction activities shall be placed 30 days prior to beginning construction and be maintained throughout the life of the project. Pedestrian,bicycle and vehicle access signage and detours as appropriate shall be per plans approved by the City of Renton Parks Division and the Developmenti Services Division. 3. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project engineer of record to the public works inspector.

Haul hours shall be restricted to 8:30 a.m.to 3:30 p.m. unless approved in advance by the Development Services Division. 5. The public works inspector shall be included in any regular construction meetings for coordination. A copy of the minutes of any regular construction meeting shall be provided to Development Services Division for their use. 6. Road restoration standards for Riverside Drive shall be a minimum of 2 inches of Class"A"asphalt over 4 inches of Class"E"asphalt over 6 inches of crushed rock. 7. Any damage or service interruptions to fire services or hydrants shall be coordinated with the appropriate owner utility or agency. Both the Boeing and City of Renton fire departments shall be notified of any water/fire lines to be taken out of service for any period of time. Hydrants shall be bagged for as long as they are taken Out of service. 8. The applicant shall reach an agreement with the City of Renton Community Services Department and the Development Services Division regarding the placement of landscaping prior to the issuance of construction permits. 9. The applicant shall obtain all required City easements for the proposed project prior to the issuance of construction permits. 10. The applicant shall submit a foreign object control plan to the airport area to the satisfaction of the Development Services Division priori to the issuance of any construction permits. 1 11. A separate traffic control plan for the airport and park shall be submitted to the satisfaction of the Development Services Division prior to the issuance of any construction permits. 12. The existing pedestrian trail along the east side of the Cedar River shall be kept open from the start of the project until June 15, at which time it will be closed. The trail shall be maintained during this time with a minimum width of 6 feet if there is a detour.

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.

PROJECT DESCRIPTION/BACKGROUND The applicant seeks to upgrade the existing sewer main that connects the Bryn Mawr area to the Metro transmission line. The pipe installed will vary from 24" to 36" in diameter. The applicant has also requested a Shoreline Substantial Development Permit as a portion of the work will be within 200 feet of the Cedar River and Lake Washington. The Bryn Mawr sewer system is an older system. The section of sewer main that is scheduled for replacement can no longer handle the peak flows. When these peak flows occur, untreated sewage can be released directly into Lake Washington. The project will provide a sewer main that can handle the peak flows and improve the water quality in Lake Washington by preventing the overflow conditions. There are two other projects that are scheduled to occur in this area within a short time frame. The City of Renton is working with the US Army Corps of Engineers on the dredging of the Cedar River. The Boeing Company has obtained land use permits for the replacement and upgrading of storm drainage lines in this area. Metro and Boeing have agreed to coordinate their projects with Metro taking the lead in the construction of the storm and sewer lines. The intent of all the agencies involved in these projects is to coordinate the work so that areas that are disturbed can be restored at the conclusion of all three projects without one project having to tear up the restoration work of the previous project. The Metro/Boeing work should be completed first. They HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Hearing Examiner BRYN MAWR SYSTEM IMPROVEMENTS LUA-97-195, CU,ECF PUBLIC HEARING DATE: February 3, 1998 Page 4 of 9 will need to fully restore the areas that their project will impact that will not be impacted by the dredging work. Those areas that will be impacted by all the projects would only require minimal restoration until the dredging work is completed. The cost of this restoration would need to be assessed to all three projects. The agreement regarding the restoration work and the costs involved in that work will need to be concluded prior to the issuance of construction permits. The applicant will also need to obtain easements from the various property owners prior to initiating any construction work. This would include existing leaseholders of airport property, the airport itself, the City Community Services Department, and the Boeing Company. It has also been reported to City staff that the proposed line will be crossing private property outside of the City limits and that the property owner has not reached an agreement with King County regarding the placement of the line. Although this is outside of the City's jurisdiction, it would not be logical to construct the portion of the sewer main in the City of Renton until it was assured that the line could connect with the remainder of the line. 2. ENVIRONMENTAL REVIEW King County accepted the lead agency status for Metro project. Environmental Review was conducted under the King County Ordinances and the State SEPA regulations. King County issued a Determination of Non-Significance on May 23, 1997. 3 COMPLIANCE WITH ERC MITIGATION MEASURES N/A 4. STAFF REVIEW COMMENTS Representatives from various city departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH CONDITIONAL USE CRITERIA Section 4-31-36 lists 11 criteria that the Hearing Examiner is asked to consider, along with all other relevant information, in making a decision on a Conditional Use application. These include the following: HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Hearing Examiner BRYN MAWR SYSTEM IMPROVEMENTS LUA-97-195, CU,ECF PUBLIC HEARING DATE: February 3, 1998 Page 5 of 9 (5A) CONSISTENCY WITH THE COMP. PLAN, ZONING CODE& OTHER ORDINANCES: The proposed use shall be compatible with the general purpose, goals, objectives and standard of the Comprehensive Plan, the Zoning Ordinance and any other plan, program, map or ordinance of the City of Renton. (1) COMPREHENSIVE PLAN LAND USE ELEMENT The project site extends across an area that is designated as Employment Area - Industrial on the Land Use Element Map of the Comprehensive Plan. The proposed project is consistent with the Comprehensive Plan Land Use Element. Policy U-2: Promote the collocation of new public and private utility distribution lines with planned or pre-existing systems (both above and below ground) in joint trenches and/or right-of-ways where environmentally, technically, economically and legally feasible. The applicant will be utilizing the same utility corridor but will be located in separate trenches due to constraints that make it impossible to locate the lines in the same trench. Policy U-61: Coordinate with the regional wastewater agency and adjacent jurisdictions in the planning and maintenance of regional wastewater systems in and near the City. In this case, King County is the regional wastewater agency. They have taken on the role of providing this section of sewer main for the Bryn Mawr area and coordinated their work with the City of Renton utilities. (2) ZONING CODE The Renton Municipal Airport and the park are zoned Public Use (P-1). The Boeing Company area is zoned Heavy Industrial (IH) and the remainder of the site is zoned Light Industrial (IL). The proposed line is allowed in these zones provided that a conditional use permit is approved. (3) DEVELOPMENT STANDARDS: (a) SIZE OF USE The applicant is requesting approval to replace an existing sewer line with a 36" sewer main. (b) LANDSCAPING The majority of the line will be constructed in areas where there is only a paved surface. However, portions of the project will be located within the Park and in the landscaped areas of the parking lot. This landscaping will need to be replaced open completion of the installation of the sewer main. The applicant will need to reach agreement with the City of Renton for the landscaped portions of the project that will be further disturbed by the Cedar River dredging project. HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Heating Examiner BRYN MAWR SYSTEM IMPROVEMENTS LUA-97-195, CU,ECF PUBLIC HEARING DATE: February 3, 1998 Page 6 of 9 (58) COMMUNITY NEED: There shall be a community need for the proposed use at the proposed location. In the determination of community need, the Hearing Examiner shall consider the following factors, among all other relevant information: (a) The proposed location shall not result in either the detrimental over concentration of a particular use within the City or within the immediate area of the proposed use. This project will.not cause a detrimental over concentration of sewer mains in this area. Open completion of this project, the area will appear similar to its present appearance. No new above ground structures are contemplated as part of this project. (2) That the proposed location is suited for the proposed use. The proposed site is suited for this purpose. The City has received one letter indicating that the soft soils along the N 6th Street portion of the site will carry construction vibrations into the adjacent residential area. The applicant will need to comply with the existing City Ordinances regarding times of construction and noise. (5C) EFFECT ON ADJACENT PROPERTIES: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. The following site requirements shall be required: (1) Lot Coverage: '.Lot coverage shall conform to the requirements of zone in which the proposed use is to be located. No new areas will be covered by structures as a result of this project. (2) Yards: Yards shall conform to the requirements of the zone in which the proposed use is to be located. Additions to the structure shall not be allowed in any required yard. No yard setbacks are required for underground utilities. (3) Height: Building and structure heights shall conform to the requirements of the zone in which the proposed use is to be located. Spires, belltowers, public utility antennas or similar structure may exceed the height requirement upon approval of a variance. Building heights 'should be related to surrounding used in order to allow optimal sunlight and ventilation, and minimal obstruction of views from adjacent structures. N/A (5D) COMPATIBILITY: The proposed use shall be compatible with the residential scale and character of the neighborhood. (Ord 3599, 1-11-82) Although the size of the sewer line is determined by a regional need, the Bryn Mawr Sewer District,the pipe itself will be underground and will not have an impact on the neighborhood once the construction has been completed. The construction activity required to install a 36" sewer line is not significantly different from the construction activity for a smaller sized line that would serve a smaller area. HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Heating Examiner BRYN MAWR SYSTEM IMPROVEMENTS LUA-97-195, CU,ECF PUBLIC HEARING DATE: February 3, 1998 Page 7 of 9 (5E) PARKING: Parking under the building structure should be encouraged. Lot coverage may be increased to as much as seventy-five percent(75%) of the lot coverage requirement of the zone, in which the proposed use is located, if all parking is provided underground or within the structure. (Ord.3903, 4-22-85) No parking will be required for this project. (5F) TRAFFIC: Traffic and circulation patterns of vehicles and pedestrians relating to the proposed use and surrounding area shall be reviewed for potential effects on, and to ensure safe movement in the surrounding area. The applicant will need to submit final construction plan including a traffic control plan. This will ensure that emergency vehicles can access the site and adjacent properties without delay. The applicant will also need to restore any streets damaged during the construction of this project. (5G) NOISE, GLARE: Potential noise, light and glare impacts shall be evaluated based on the location of the proposed use on the lot and the location of on-site parking areas, outdoor recreational areas and refuse storage areas. Potential noise impacts can be created during the construction phase of the project. The applicant will need to comply with the City of Renton Noise Ordinance. (5H) LANDSCAPING: Landscaping shall be provided in all areas not occupied by building or paving. The Hearing Examiner may require additional landscaping to buffer adjacent properties from potentially adverse effects of the proposed use. The applicant will not be required to landscape any new areas as part of this project. The applicant will need to restore landscaping that is disturbed by this project. In the event that landscaping will be further disturbed by subsequent projects the landscape restoration may be deferred by reaching an agreement with the City of Renton. The areas that are disturbed and that will not be immediately replanted to match existing landscaping will need to have temporary erosion control measures installed and maintained until such time as the final landscaping can be installed. (51) ACCESSORY USES: Accessory uses to conditional uses such as day schools, auditoriums used for social and sport activities, health centers, convents, preschool facilities, convalescent homes and others of a similar nature shall be considered to be separate uses and shall be subject to the provisions of the use district in which they are located. N/A HEXRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Heating Examiner BRYN MAWR SYSTEM IMPROVEMENTS LUA-97-195, CU,ECF PUBLIC HEARING DATE: February 3, 1998 Page 8 of 9 (5J) CONVERSION: No existing building or structure shall be converted to a conditional use unless such building or structure complies, or is brought into compliance, with the provisions of this Chapter. N/A (5K) PUBLIC IMPROVEMENTS: The proposed use and location shall be adequately served by and not impose an undue burden on any public improvements, facilities, utilities, and services. Approval of a conditional use permit may be conditional upon the provision and/or guarantee by the applicant of necessary public improvements, facilities, utilities, and/or services. The proposed project will be put through areas where a number of existing utility lines (public and private) are located. The applicant will need to coordinate any service disruptions with the appropriate agencies or owners.

Pywell,ACIP,Project Manager Development Services Division 200 Mill Avenue South Renton, Wa. 98055 Subject: Questions and Comments on Application for project LUA-97- 195,CU-H,SM/ Bryn Mawr System Improvements 1) Is this project really necessary? 2) What is the benefit to the City of Renton and affected. residents? Please explain why an unincorporated area should be allowed to run their sewage through the City of Renton for disposal. We are opposed to continuing a precedent which would make it easier for other areas/cities to route their sewage to Renton. The damage to houses and contents which resulted fram construction of the existing Metro sewer line when it was first installed is still a vivid memory to me. We are concerned about the magnitude of earth/ground vibrations which would be generated by this project(particularly from pile driving operations) . We are also concerned about the noise and the hours during which the work would be done since contractors have little or no consideration for nearby residents. We have observed contractors who will start their work early in the morning and end their work late in the evening if allowed to do so. What are your plans for re-routing the large amount of automobile and truck traffic which will be affected by this project? The use of residential neighborhood streets in this area to accamodate Boeing shift change traffic because of this project would be unacceptable. Beverly K.

COMMENTS DUE: JANUARY 20, 1998 • APPLICATION NO: LUA-97-195,CU-H,SM. DATE CIRCULATED: JANUARY 06, 1998 APPLICANT: King County/Dept. of Natural Resources PROJECT MANAGER: MARK R. PYWELL PROJECT TITLE: Bryn Mawr System Improvements WORK ORDER NO: 78324 LOCATION: Renton Airport, Cedar River Trail Park, North 6th Street SITE AREA: N/A I BUILDING AREA(gross): N/A SUMMARY OF PROPOSAL: The applicant seeks to upgrade the existing sewer main that connects the Bryn Mawr area to the Metro transmission line. The pipe installed will vary from 24".to 36",in diameter. The applicant has also requested a Shoreline Substantial Development Permit as a portion of the work will be within 200 feet of the Cedar River and Lake Washington. A.

B. POLICY-RELATED COMMENTS The airport property is not public right-of-way. Although an easement is being sought„by Metro, an agreement between the City and Metro concerning responsibility for maintenance and/or repair of the ground area above and surrounding the pipeline, and responsibility for any damage which may be caused to the runway and/or taxiway in the event of failure or leaking of the pipeline, should be obtained prior to permitting the placement of the sewage pipeline beneath the airport property. This agreement could be contained within the easement or as a separate agreement tied to the easement. Responsibility for actions after the abandonment of the. pipeline (and possible collapse of the deteriorated pipe) should hp contained within the agreemPnt. C. CODE-RELATED COMMENTS A Notice of Proposed Construction must be submitted to the FAA prior to <issuziing.;a Permit, since this is on -airport construction. We have reviewed this application with particular attention to those areas in which we have expertise and have identified areas of probable impact or areas where add al informatio needed to properly assess this proposal. fife 0 ,JOAL /5 In' Signature A Director or Authorized Representative Date DEVAPP.gbc Rev.10/93 1 . ._,.'-- -)iiicir ,, --w-1-- . „at- 1 0121 11.41•1 iiii .. , Ik ) q , to e•-i, „%ioLi../._.

Proposed Hours of Operation: The hours of construction are planned to be 24-hours a day. This will expedite work in the Cedar River Trail Park,Renton Municipal Airport,and the Cedar River crossing area. Work in the Park is from the intersection of N. Oh Street and Riverside Drive N., along Riverside Drive N.to the Cedar River crossing. The Cedar River Crossing involves microtunnelling from the Park,westward under the Cedar River and Renton Municipal Airport to the restaurant parking lot. The 24-hour work day is planned in order to complete the work within strict time limitations. The County contractor must be out of the Park in time to allow the USACE contractor to mobilize and commence river dredging and levy construction. It is anticipated the USACE contractor will commence construction in the beginning of August, 1998. Proposed Hauling/Transportation Routes: Proposed hauling and transportation route for the east side of the project is likely to be along Riverside Drive N.southward to N.6`h Street,then eastward along N.6th Street to Logan Avenue. Routes will then continue either eastward along N. 6th Street towards Park Avenue N or southward along Logan Avenue towards SW Sunset Boulevard. Proposed hauling and transportation route for the west side of the project will be along the airport's West Perimeter Road to Rainier Avenue S. Traffic may either continue northbound or southbound on Rainier Avenue S. Measures to be Implemented to Minimize Construction Impacts: The contractor will implement Best Management Practices(BMT's)in order to minimize construction impacts on the surrounding area. Dust from the project and it's effect on surrounding areas will be controlled by washing trucks,covering loads prone to producing dust,and spraying water on areas yet to be restored where dust may be blown from construction activity or wind. Paved areas will be swept regularly either with a street sweeper or manually. Traffic and transportation impacts will be mitigated through the implementation of a traffic control plan submitted by the Contractor. Whenever possible and as the construction schedule permits,the contractor will be expected to haul materials during off-peak traffic times. The Contractor will be required at all times to have BMT's in-place which help prevent mud,erosion,and siltation to adjacent areas. Erosion control methods shall be used to prevent silt-laden water from entering the Cedar River,Lake Washington,or the adjacent stormwater facilities. Tliage fk cgE,y3 to include; • -ti b dsLL;r-,;VIEN7 PLANNING CITY OF RENTON but are not limited to;straw bales,filter fabric,catch basin inlet protection,silt fences,check dams,and mulching of exposed areas. The contractor is to have all construction equipment fitted with appropriate noise muffling and/or reducing devices in order to minimize the effects of noise in the vicinity of the project. The contractor will be expected to meet the requirements of the City of Renton Noise Ordinance and applicable OSHA and WISHA standards. Special Hours Proposed for Hauling Due to the compressed schedule for work to be completed in the Park,the construction contractor will need to haul 24-hours throughout the day while constructing within the Park area. This is also due to the lack of space along N. Sixth Street and Riverside Drive N. There is little room available for the stockpiling of materials. Preliminary Traffic Control Plan: The contractor will be required to submit a detailed traffic control plan to the County for review. The traffic control plan is likely to include the following features: Eastside of the Project: • Along N. 6'h Street,there will be one lane of traffic during construction of the King • County sewer line from the Eastside Interceptor to the park entrance. This will be the northern lane of N. 6'h Street • The,traffic along N.6th Street will be directed and controlled by flagmen posted near the intersection of N. 6'h Street and Logan Avenue,the entrance to the Boeing Parking Lot,and near the Apron D access at the Park entrance. • There will be no vehicular access by the public to the park. This is due to tight access and space constraints. There will only be access for construction vehicles. Westside of the Project: • Construction traffic will be approaching from the north from the restaurant parking lot to Rainier Avenue South. • Traffic control will be provided at the intersection of the Perimeter Road entrance to Rainier Avenue. • Traffic control will involve flagmen to direct construction traffic and control regular traffic when construction equipment is moving onto and off from Rainier Avenue. • Traffic will also be controlled when necessary from the south approach of the West Perimeter Road to Rainier Avenue. • Traffic control will involve flagmen to direct construction traffic and control regular traffic as it access Rainier Avenue South from the Perimeter Road. .

A. Comprehensive Plan: The proposed use shall be compatible with the general purpose, goals, objectives, and standards of the comprehensive plan, the zoning ordinance, and any other plan, program, map, or ordinance of the City of Renton. The Comprehensive Plan designates the site as Employment Area-Industrial (EAI). As with other utility uses, no area of the City are.specified for this use in the Comprehensive Plan. The proposal will compatible with the following applicable Policies and Regulations. General Policies Policy U-2. Promote the co-location of new public and private utility distribution lines with planned or pre-existing systems in joint trenches and/or right of ways where environmentally, technically, economically and legally feasible. { To minimize impacts, the proposed pipeline will be jointly constructed with a new. Boeing stormdrain interceptor within Cedar Rive Trail Park. The joint construction is intended to precede dredging of the Cedar River by the US Army Corps of • • Engineers which will also impact the park. The proposed pipeline will also replace the existing sewer pipeline within Cedar River along much of its alignment. Wastewater Systems Policy U-61. Coordinate with the regional wastewater agency and adjacent jurisdictions in the planning andtmaintenance of regional wastewater systems in and near the city. Policy U-63. Coordinate with the regional wastewater agency and adjacent jurisdictions to ensure that wastewater lines passing through Renton are operated in a safe manner at all times. KingCounty, as the regional wastewater agency, is proposing these improvements. 9 9 Y; p p g p King County is also coordinating with the Bryn Mawr-Lakeridge.Sewer and Water District to provide additional capacity and reduce overflows to Lake Washington. Shoreline Master Program Regulation 7. 18.02 Special Considerations for Pipelines Installation and operation of pipelines shall protect the natural conditions of adjacent water courses and shorelines. A. Water quality is not to be degraded to the detriment of marine life nor shall water quality standards by violated. B. Native soils shall be protected from erosion and natural conditions restored. Water course banks and bottom's shall be protected, where necessary, with suitable surface treatment. The proposed pipeline will not be constructed within Lake Washington or the cedar River., The pipeline will be tunneled beneath the Cedar River, which.may necessitate the removal of old, existing piling within the river. No other inwater work is anticipated. Best Management Practices shall be employed to avoid impact to water quality and erosion. All disturbed areas shall be restored to existing or better condition; including landscape restoration. Regulation 7. 18.03 Major Utilities-Specifications . C. Pipeline Utilities: All pipeline utilities shall be underground. When underground projects are completed on the bank of a water body or in the wetland or a shoreline, the disturbed area shall be restored to the original configuration. Underground utility installations shall be permitted only when the finished installation shall not impair the appearance of such.areas. The proposed facilities shall be 'underground. Restoration shall be completed to original or better condition. Regulation 7. 18.05 All-inclusive Utility Tunnels: For the distribution of local utilities, utility tunnels under the street right of way are recommended to carry all local utility services. For new development, the tunnel could be built at the time of road construction. The tunnel would include all utility services, both public and private, necessary for use in the,public right of way, such as wiring for street lighting and water lines for fire hydrants and all utility services necessary for the private uses of the are.The proposed pipeline is a regional collector pipeline and does not provide local service. Segments of tunneling will be required beneath the airport runways, and beneath Logan Street to avoid air and vehicle traffic conflicts. B. Community. Need: There shall be a community need for the proposed use at the proposed location. In the determination of community need, the Hearing Examiner shall consider the following factors among all other relevant information: 1) The proposed location shall not result in either the detrimental over- concentration of a particular use within the City or within the immediate area of the proposed use. 2) That the proposed location is suited for the proposed use. The proposal will reduce overflows of sewage to Lake Washington due to capacity limitations of the existing conveyance system, thereby improving water quality. The proposal will not affect proposed uses in the area. The alignment of the pipeline was chosen after consideration of several alternatives (please see Pre-Design Report, Bryn Mawr, June 1997 submitted with this. application) The selected alignment has fewer environmental impacts, avoids inwater construction, and can be completed at less cost than other alternatives. ; The alignment is proposed primarily within existing transportation corridors. C. Effect on Adjacent Properties,: .The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. The proposal will result in temporary impacts from the construction of the underground facilities. Following restoration, not adverse effects are anticipated on adjacent properties. Y ' Review Criteria • Lot Coverage; Yards; Height N/A • Compatibility - the facilities will be underground and located in P-1 and Heavy Industrial zones. • Parking - N/A • Traffic - Temporary impacts will result from construction, such as one-lane traffic on N. 6th Street and Burnett Street, and closure of the Cedar River Trail Park access roadway. No long term traffic impacts are expected. • Noise, Glare - Temporary impacts will result from construction equipment only. • Landscaping - All disturbed landscaping shall be restored in kind. • Accessory Uses; Conversion - N/A • Public Improvements = The proposed improvements will ensure adequate service capacity for the Bryn Mawr-Lakeridge Sewer District to reduce overflows to Lake Washington. We look forward to participating in the City of Renton's review of our proposed improvements. I can be reached at 296-7816. Thank you.

King County's project is called the Bryn Mawr System Improvements and is described as follows: The Problem: The Bryn Mawr-Lakeridge Sewer and Water District, located in unincorporated King County, discharges sanitary sewer flows to the King County wastewater treatment system near the southwest.corner of Lake Washington. These flows are delivered via the Bryn Mawr Trunk to King County's East Side Interceptor. Due to the limited capacity of the existing Bryn Mawr Trunk, and infiltration and inflow to the Bryn Mawr-Lakeridge system, untreated sewage overflows into Lake Washington approximately five times a year. The Project: King County has determined that the most appropriate strategy to reduce overflows • into Lake Washington consists of increasing the capacity of its conveyance system and initiating a program to reduce infiltration and inflow to the Bryn Mawr-Lakeridge system. The existing King County/Bryn Mawr conveyance pipeline system starts at a location immediately northwest of the City of Renton airport (on private property) and proceeds easterly into Lake Washington just north of the airport, it then turns south and enters the north end of the Cedar River Trail Park. The pipe proceeds south down Riverside Drive to North Sixth Street, at that point it turns east down North Sixth Street until discharging into the East Side Interceptor (ESI) located in Burnett Avenue North at North Sixth Street. To increase the capacity of the existing conveyance system it is proposed that a new pipe be installed which generally follows the same alignment, but avoids in- water construction. The proposed alignment is as follows: 1) Beginning near the northwest corner of the Renton airport, a 24" pipe will be installed along the west and south sides of the existing restaurant building (formerly Mindemann's), a short section of the pipeline in this area will be located with the Urban shoreline designation of the City of Renton. The pipeline will then be tunneled under the north end of'',the airport, the Cedar River, and into Cedar River Trail Park. The pipeline crosses'an area that historically was a portion of Lake • Washington and a large fresh water marsh that was reclaimed over a number of years by random filling. The shoreline of the Cedar River is a low, sandy embankment, prone to flooding., The airport is a P-1 zone. This portion of the pipe alignment will be an inverted siphon and operate under low pressure. 2) Within Cedar River Trail Park,; the existing pipe will be removed and replaced with a new, larger, 36" pipe along Riverside Drive. 3) Within North Sixth Street, the existing pipe will be abandoned in place and a new 36" pipe will be laid parallel to and.south of the existing pipe. The pipe will be tunneled under Logan Avenue North to avoid traffic impacts. The extreme north portion of the project, north of the airport, is within unincorporated King County. The remainder of the project is within the City of Renton. For the project segment within Cedar River Trail Park, the pipeline will be jointly constructed with the previously permitted Boeing stormdrainage interceptor. I suggest that Mark Pywell be involved in project review, since he reviewed Boeing's project. Public notice of both Conditional Use and Shoreline permit applications will be required. Since the pipeline alignment is primarily located outside street rights of way, King County will be negotiating the acquisitions of easements necessary for the construction of these improvements. Easements will be necessary from the City of Renton for pipeline segments across the Renton Municipal Airport, beneath the Cedar River, and through Cedar River Trail Park. Easements will also be required from The Boeing Company for segments crossing parking lots near Logan.Avenue North and N. 6th Street. We propose to provide you with the appropriate evidence of easements/agreements from the property owners prior to permit issuance. Since these easements will not be finalized for approximately 90 days, and since permit processing must be completed before a construction contract can be awarded, we ask that Conditional Use/Shoreline Substantial Development permit review begin now in order to allow construction to commence in March 1998. This timing is important in order to finish construction of both the Boeing stormdrain interceptor and Bryn Mawr System Improvements within Cedar River Trail Park in July 1998, and make way for the Corps of Engineers' 205 project in July/August 1998. Please refer to the completed SEPA threshold determination for a discussion of construction mitigation measure's. We look forward to assisting with your project review. Please contact me at 296- 7816 whenever you have questions or would like additional information. Thank you. Sincere) ry Elli gton SR/ A Senior Real Property Agent f, .

CC: Neil Watts • • • CITY OF RENTON P.LANNINGBUILDING/PUBLIC WORKS MEMORANDUM DATE: September 9, 1997 TO: Neil Watts FROM: Dave Christen SUBJECT: Bryn Mawr System Improvements - 60% Submittal Per our recent conversation, I am passing on the 60% submittal for the subject project to your staff for review. At Gregg's request, I have reviewed this project for potential impacts related to the possibility of open cut on the portion along N. 6th Street. Metro has proposed the use of jack and bore for the portion of the project within the Logan St crossing to.Burnett. West of this location, they are proposing open cut. The depth of this portion of work varies from 20 feet to 15 feet. To hold the trench, the contractor will probably need to drive sheets or some other method for creating a stable trench environment other than the traditional trench box method. The surrounding uses along this alignment are primarily parking lots to support Boeing. Towards the west end, a portion of Boeings Commercial Airplane operations exist in the form of outdoor, parking facilities. With these adjacent uses it does not appear that open cut will have a significant impact on the adjacent uses and as such, the need to perform trenchless operations in this area does not appear to be • required. The only other mitigating factor to this will be the impact to Boeing users entering and existing this portion of the project area. Again, in a quick look of the adjacent facilities, it appears that Boeing would be able to direct the majority of its employees along Logan to keep them from this portion of N. 6th Street. I have spoke with Gregg on this and he generally agrees that Metro's proposed methodology for construction is acceptable as long as they can show that they are able to adequately address the issue of traffic control through this reach.

Pywell, AICP SUBJECT: Bryn Mawr System Improvements Pre-App 97-103 We have completed a preliminary review of the pre-application for the proposed development. The following comments on development and permitting issues are based on the pre-application submittals made-to the City of Renton by the applicant. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision makers (e.g., Hearing Examiner, Zoning Administrator, Board of Adjustment, Board of Public Works, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. 1. The project is to construct a 36"sanitary sewer line across the airport's north end (P-1 Zoning), under the Cedar River, through the Cedar River Park (P-.1 Zoning), along N. Riverside Drive, along N. 6th Street, and across a parking lot (IL Zoning). The public right-of-way for streets in Renton is not zoned. 2. This project will require SEPA review, Shoreline Substantial Development Permit, and Hearing Examiner Conditional Use Permit. 3. Pipeline on drawing C101 appears to pass through a landscaped island in a parking lot. Can this be rerouted to avoid the required landscaping? If not, how will the landscaping be restored and what will it include? 1.•=1,(�.� - � 4. There is a lot of work programed for the Cedar River in the next couple of years (Boeing Pipelines, dredging work in the river, & dike work in the park) how will the landscaping and design of these project be coordinated? 5. The Airport Supervisor, Gail Reed, has expressed concerns and requirements for this project. How will these be addressed? 6. What is the proposed time line for this project? From: Gail Reed To:Mark R.Pywell Subject:Bryn Mawr System Improvements on/near Renton Airport Date:Monday,November 03, 1997 3:45PM Mark, Major issues that must be resolved prior to formal land use arid/or building permit application submittal: 1. To my knowledge, no City,of Renton engineering department has reviewed the proposal to determine that the proposed boring will NOT affect the runway. — K. jc-W'►eark GG-1z3);a',.s3o-. 2. The proposal is being sent to the Seattle Airports District Office this week by Larry Ellington,for a review of the design and a determination of compatibility with the airport operations. The FAA MUST approve the design before land use/building permits may be issued. 3. The property at the northwest corner of the airport is leased to Specialty Restaurants, currently in default to the City. Permission for the use of this property must be obtained by Metro from the Lessee,unless other guidance is obtained from the City Attorney's office. I recommend that David Dean,from the City Atty's office, attend the meeting to furnish information on legal implications. 4. I am very concerned about the construction process. Although this meeting is to review the 60%plans,things have a way of moving very fast and the next thing I know the contractor is wondering where he can stage materials. There are not now, and there will not be,any place a contractor may stage materials. Everything will have to be hauled in and hauled out daily, unless space is obtained at;the restaurant area. When the construction moves to the runway edge,as proposed on the east side,haul in and haul out will be the requirement. 5. I will not permit work to begin until I have received concurrance from the FAA and am satisfied with the work plan from Metro and the contractor. • CITY OF RENTON PLANNINGBUILDING/PUBLIC WORKS MEMORANDUM • DATE: November 3, 1997 TO: Mark Pywell rati FROM: Rebecca Lind STAFF CONTACT: Troy Schlepp (277-6167) SUBJECT: Bryn Mawr System Improvement-Long Range Planning Comments (on and near the Renton Airport) The Comprehensive Plan designates the site as Employment Area-Industrial (EAI).

Dear Mr. Goon: I . Thank you for the opportunity to comment on this project,most of which will be constructed in the City of Renton. We have reviewed the environmental checklist for the proposed project and have found several responses that we believe are incorrect and would like to see the applicant correct. We also have included comments on the scheduling and methodology of construction which are intended to reduce the environmental impacts of this project. on the City of Renton. These. comments will likely not alter the threshold determination but are important for reducing impacts • on Renton's facilities and infrastructure. We are recommending that the comments on scheduling and methodology be incorporated as conditions on the environmental determination.. Our comments are listed below. If you,have any questions please contact Gregg Zimmerman at 277- 6211. Please note that these comments represent the views of the City of Renton's Planning/Building/Public Works Department. Other City of Renton Departments may submit their own comments on this project. Scheduling and Methodology of Construction: 1) Trenchless construction'(micro tunneling,boring,jacking, etc.)is strongly recommended for the portion of the interceptor within the N. 6th Street alignment, particularly the section at Logan Street and Burnett Street. Depth of bury(to top of pipe) ranges from about 12-feet to nearly 20 feet along this alignment. Impact to the roadway • and transportation needs of the proposed open trench construction will be significant. This impact could be reduced by judicious use of trenchless technology. It should be noted that Boeing has access to its facilities off of N. 6th St., and also that this street may be needed • as a haul route for Cedar River dredging spoils. • 2) Three projects are proposed along the east bank of the Cedar River within the same . • general time frame: the Bryn Mawr System Improvements,Boeing's storm water . interceptor,line, and Renton's and the Army Corps of Engineers' 205 Cedar River flood • • mitigation project. The accumulative impacts of these three projects could cause the popular Cedar River Trail to be closed to the public for up to three years: It is strongly • recommended that the agencies sponsoring these three projects coordinate common time dines on these projects in such a way as to reduce the accumulative•impact of the projects on the trail. • 200 Mill Avenue South - Renton, Washington.98055 Page 2 June 13,1997 • General References throughout the document to the Cedar River Park should be changed to the Cedar River Trail. Cedar River Park is located east of I-405 between the Cedar River on the south and Maple Valley Rd(SR-169)on the north. Phased Construction,pg.4. The narrative in paragraph five states that Phase I which includes sewer pipe construction activity would be implemented in the fourth quarter of 1997 and could last two or three months. It should be noted that flooding of the Cedar River often occurs during the last and first quarters of the year and also the water table during this time of year typically is higher than during the third'quarter. Environmental Elements, Surface Water, pg. 9, 10 The response to Item B.33.a.2) states that `[c]onstruction of the proposed system improvements would require work adjacent to Lake Washington and the Cedar River. No construction would occur within the lake or river." However; on page 6 the narrative states that the`project corridor extends from an incorporated area immediately west of the Renton Municipal Airport,'along the City of Renton's Cedar River Park and ends at the intersection of N. 6th Street and Burnett Street within the City of Renton." Both the narrative and attached Figure 1. describe/show the Bryn Mawr Siphon crossing the Cedar River parallel to 115th Place, if extended..'It would appear from the drawing that work would occur within the Cedar River. As a minimum, even if this work is accomplished by tunneling, the response here should state that 'the work would occur on lands covered by water." Likewise, Item 3.a.5) appears to be in error. In response to the question 'Does the • proposal lie within a 100-year floodplain?, the applicant's response is 'No." We have reviewed the FEMA National Flood Insurance Rate Maps for the mouth of the Cedar and south along the Renton Municipal Airport and these maps clearly indicate that project area depicted in Figure 1.is within the`special flood hazard area inundated by 100-year flood." This should be corrected before the final environmental determination is issued. Under ItemB.3.c.2) Water{Runoff, on page 10 the response to the question `Gould waste material enter ground or surface waters? If so, generally describe."The applicants have • responded: `The project does not propose discharging waste material of any kind into ground or surface waters."' However, elsewhere in the checklist we are told that ground water would be discarded to the `sanitary sewer, local storm drainage facilities or to the Cedar River depending upon water volumes and quality." On page 12 under Item B.7. Environmental Health the checklist narrative states that `[c]ontaminated groundwater and soil_are likely to be encountered. during construction within Cedar River Park [sic]. — Volatile organic compounds have been found in groundwater samples collected within • Cedar River Park [sic]." Given the amount of dewatering required for this project and the • likely encountering of contaminated groundwater and soil, it would appear that waste 'material could enter•ground,water or surface waters. Item 3.c.2)Water Runoff on page 10 should be corrected to state that dewatering could result in contaminated groundwater being discharged into surface waters. Under ItemB.3.d. regarding `Measures to reduce or control surface, ground and runoff impacts, if any"no measures are listed. The narrative says that these " . . . will be ' Page 3 June 13,1997 included in the project's construction contract specifications." How is the reader to know whether adequate techniques are proposed for this environmentally sensitive area? WAC 197-11-335 states that the lead agency shall make its threshold determination based upon information reasonably sufficient to evaluate the environmental impact of a proposal. Without knowing what measures, if any, are to be employed to reduce or control surface, ground and runoff impacts, it is difficult to assess whether potential impacts in this area are mitigated, or not. Item B.7.b.2),pertaining to noise, states that construction noise levels could be expected to range from 79 to 88 dBA measured at a distance of 50 feet from the source. Since the City's and County's noise ordinances are predicated on noise measured at the edge of the receiving zone it is unclear whether noise levels will comply with adopted noise regulations. Residential receiving sites in both the County and City restrict levels in excess of 60 dBA except these can go up to 70 dBA when not exceeding 5 minutes in any one hour or 75 dBA when not exceeding 1.5 minutes in any one hour. Reference is made that although weekend or evening work is not anticipated it may be employed to avoid construction related disruptions. It should be noted that nighttime (10 PM to 7 AM) noise levels are typically reduced by 10 dBA from those shown above. Item B.8., Land and Shoreline Use, under "c"where the applicant is asked to "describe any structures on the site"states their response as `hone." Since the project description indicates that the project will pass through the area where Mindemann's Restaurant is located as well as park sites with structures on them, it would appear more correct to state that there are structures on the project site but note that none are proposed to be demolished, etc. Under `I" where the applicant is asked to give the `current comprehensive plan designations of the [project] site"the applicants have given this for King County but not correctly indicated those for Renton. Since virtually all of the project is in Renton, this should be corrected. Renton's Comp Plan designations for the project"site"include:Employment Area-Industrial, and Residential Single Family.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The Bryn Mawr siphon is the connection point between the Bryn Mawr-Lakeridge • Sewer District and the King County sewer system. When heavy rainfall occurs,the siphon's capacity is exceeded causing overflows into Lake Washington. The Bryn Mawr System Improvements project was selected by King County to eliminate the ' six to ten overflows that occur annually. This objective would be achieved by increasing system conveyance capacity. The Bryn Mawr System has two components: 1) the Bryn Mawr Siphon and.2) the Bryn Mawr Trunk Sewer. The Bryn Mawr Siphon consists of an inlet structure, an outlet structure and approximately 1,500 linear feet of 8 and 14-inch diameter inverted siphon constructed in Lake Washington. The Bryn Mawr trunk is a 27- �/ inch diameter gravity sewer which extends from the siphon outlet structure to the Eastside Interceptor at the intersection of North 6th and Burnett streets. The length ' of the Bryn Mawr,Trunk is approximately 4,400 feet. The project location and' system elements are shown in Figure 1. 2 Bryn Mawr System Improvements • Environmental Checklist • • r: '• ;;:.,I BRYN MAWR SIPHON, PROPOSED PHASE II FIGURE 1 - m • BRYN MAWR TRUNK, PROPOSED PHASE !

Ar King County is proposing to construct and operate a third siphon barrel 24-inches in diameter and replace the 27-inch Bryn Mawr Trunk with a larger 36-inch pipe.The • Figure 1. proposed project can be described in terms of the three elements below. • Construct a new siphon inlet connection for the third barrel immediately upstream of the existing siphon inlet. This connection would be a below- ground structure. • Construct a new 24-inch inverted siphon approximately 1,700.feet in length. This siphon would operate as a third barrel to the existing siphon. The 24-inch barrel would convey flows from the new siphon inlet structure to a connection with the Bryn Mawr Trunk. • Remove and replace the existing Bryn Mawr Trunk(27-inch reinforced concrete pipe) with a 36-inch diameter reinforced concrete pipe through Cedar River Park. Construct a 36-inch diameter pipe which would parallel the Bryn Mawr Trunk along N. 6th Street. The new pipe would convey flows from the three siphon barrels to the existing Eastside Interceptor. Approximately 4,400 linear feet of pipe would be constructed. Phased Construction Construction of the proposed system improvements would occur in two phases. Phase I construction would include sewer pipe construction activities within Cedar River Park and along N. 6th Street. First phase construction would occur during the fourth quarter of 1997. Construction is anticipated to last two to three months. The remainder of the project would be included in Phase II. Activities would include construction of the siphon inlet, the third siphon barrel and connection to the Bryn Mawr Trunk. Construction of the second phase is anticipated to occur during the 1999 construction season and last approximately three months. Dewatering is anticipated to be required along the entire alignment. Siting and construction of the siphon and pipe would require acquisition of permanent and temporary easements. Sewage flow conveyance will need to be maintained during Phase I construction. Submersible pumps and pipes will be used to convey flows around those segments of the trunk under construction. . Project Elements Siphon Connection to the Existing System. A new inlet structure would be constructed to connect the new siphon barrel to an 18-inch line at a point immediately upstream of the existing siphon inlet. The inlet structure can be described as a below grade rectangular concrete vault that diverts flow into the new siphon barrel when the existing two barrels are at capacity. Construction of the inlet structure would require excavation to install the vault and to make the necessary connections to the existing conveyance system. - The outlet of the proposed third barrel would connect to the new 36-inch Bryn Mawr Trunk in the vicinity of the existing siphon outlet. The outlet connection would be made using a typical manhole structure. 4 Bryn Mawr System Improvements Environmental Checklist 24-Inch Siphon Barrel. The siphon barrel would convey flows from the Bryn Mawr-Lakeridge Sewer District connection to the Bryn Mawr Trunk. Approximately 1,700i feet of 24-inch diameter siphon would be constructed. Beginning at the siphon outlet in Cedar River Park, the alignment crosses to the west under the Cedar River and the Renton Airport into the parking lot of Mindemann's Restaurant. This portion of the alignment could be constructed in one or two'segments'using trenchless construction methods. From the parking lot the alignment continues to the west and northwest to a connection with the Bryn Mawr-Lakeridge Sewer District system. Construction methods will be employed that avoid or minimize construction related disruption to surrounding residential and commercial uses, airport operations and • the Cedar River. 'Methods of construction such as trenchless excavation methods (i.e., boring, jacking; directional drilling, microtunneling) as well as open cutting will be considered. I All trenchless construction methods would require excavation of shafts or pits in Order to conduct construction operations. For each construction reach,two pits are required. Equipment is located in one pit in order to conduct operations, and a pit is located downrange in order to receive the pipe. Typical pit sizes for boring and jacking methods are 20 x 30 feet and 20 x 15 feet, operating and receiving respectively. Pit depths could range from 10 to 15 feet. Shoring of the pit sidewalls-will be required and dewatering measures are anticipated. Bryn Mawr Trunk. The existing 27-inch reinforced concrete pipe within Cedar River Park would be removed and replaced with a new 36-inch reinforced concrete pipe. Along N. 6th Street,the 27-inch trunk would be paralleled with a 36-inch reinforced concrete pipe. The new pipe would convey flows between the proposed siphon outlet and the existing Eastside Interceptor. The replacement pipe would remain within the existing Bryn Mawr Trunk easement within Cedar River Park. Along North 6th'Street,the pipe would be located within street right-of-way. Manholes would be installed along the pipeline at approximately 400i foot intervals. Temporary construction easements will be required. Method of construction would be open cut. Excavation depths within Cedar River Park are anticipated to.range from 6 to 12 feet. Anticipated high groundwater table and loose granular soil conditions will necessitate the use of trench box or.sheetpile shoring in conjunction with dewatering measures. j . Subsurface conditions along North Sixth Street will likely be similar to those along N. Riverside Drive (Cedar River Park access road),requiring similar construction measures. Excavation depths along the final 1,000 feet of the route are expected to be 15 to 20 feet. Sheetpile shoring and dewatering will likely be necessary to satisfactorily support Ithe excavation sidewalls. ;12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan,vicinity map, and topographic map, if reasonably available. While you should submit any plans required by 5 • Bryn Mawr System Improvements Environmental Checklist the agency,you are;not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project corridor extends from an incorporated area immediately west of the Renton Municipal Airport, along the City of Renton's Cedar River Park and ends at the intersection of N. 6th Street and Burnett Street within the City of Renton. Section 7 T23N R 5E B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site: Flat, rolling, hilly, steep slopes, mountainous, other(see below). b. What is the steepest slope on the site? (approximate percent slope)? The steepest slope is found in the area of the old Bryn Mawr treatment facility. Slopes separating the abandoned treatment facility and the airport are roughly four percent. c. What general types of soils are found on the site? (for example, clay, sand, gravel,peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. - The project corridor encompasses an area that historically was once a portion of Lake Washington and a large fresh water marsh. Construction of • the Lake Washington Ship Canal lowered the-level of Lake Washington by approximately nine feet. The marsh land and the area formerly covered by the lake were reclaimed over a number of years by random filling. Previous borings in the project area described soils as three to five feet.of loose granular fill underlain by soft peat and organic silt extending to depths ranging from 13 to 25 feet. Medium-dense sand and firm clay were encountered below the soft peat and silt. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No. • e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. See the information presented in Section A. 11. for a description of construction methods. Estimated volumes of excavated material are 13,000 cubic yards for the pipeline, and 650 cubic yards for the third siphon barrel and inlet structure., The amount of imported fill required for the proposed project is dependent upon the engineering characteristics of the native soil. Native material would be used as fill or cover whenever possible. Imported material would be used to provide an engineered base or as cover material. All imported material would be subject to material specifications, inspection and acceptance by King County's project construction manager. 6 Bryn Mawr System Improvements Environmental Checklist All excavated material that cannot be used as fill shall be disposed of at an approved disposal site. There is a potential for encountering contaminated soils and groundwater along the.proposed siphon and pipeline alignment. The discussion in Section B.7.a. provides information on the potential for encountering contaminated soil and groundwater and how contaminated material would be addressed during construction. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. I Yes. Construction activities could cause erosion on a short-term basis. Construction activities•such as site clearing and grading, excavation, materials handling and stockpiling pose the greatest potential for erosion. Operation of the facilities would not pose an erosion potential. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Surface areas disturbed due to construction would be restored to pre- construction conditions. h. What measures are proposed to reduce or control erosion, or other impacts to the earth, if any? ' Except during'project construction, there would be no long term erosion impacts to the earth due to operation of the proposed system improvements. Project construction activities would employ construction related Best Management Practices such as temporary erosion and sediment control measures. Typical BMP's that could be employed are filter fabric fences, hay bales, covering soil • stockpiles and exposed soils,Using temporary soil covers such as mulch or grasses, diverting storm water away from exposed soils through.the use of berms, and use of settling ponds, or grassed swales to prevent sediment from moving into water courses, open ditches and storm drains. Other measures could include the following: - avoid excessive clearing and grading; - - limit the extent and-areas of excavation and other earthwork activities near waterways; - designate personnel to inspect and maintain temporary erosion and sediment control measures; - store construction materials away from surface waters; -maintain spill containment and clean up material at active construction sites; - install temporary erosion and sediment control measures prior to when site _ clearing and grading activities begin; - employ temporary slope protection; and -restore disturbed area by replanting or repaving as soon as practical after construction is completed. • j Temporary erosion and sediment control measures would be identified in the project plan and construction specifications documents. Erosion control and slope. • 7 • Bryn Mawr System Improvements Environmental•Checklist stabilization measures would be implemented as required by the permitting jurisdiction. Erosion control measures would be established on site prior to clearing, grading or excavation activities. Limits of construction activities would be delineated on construction drawings to maintain required buffers around water courses. 2. Air a. What types of emissions to the air would result from the proposal during construction, and when the project is completed? If any, generally describe and give approximate quantities if known. Temporary construction related air emissions would include dust caused by equipment movement and exhaust from construction equipment. Emissions would consist primarily of soil particles, carbon monoxide and hydrocarbons. . Operation of the completed project would not result in emissions. • b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. What measures are proposed to reduce or control emissions or other impacts to air, if any? Construction related dust emissions would be addressed by employing dust control measures during dry weather conditions, such as watering construction areas to wet bare soils, and cleaning roadways around the construction areas to control dust emissions. Construction equipment related emissions would be addressed by requiring proper maintenance of equipment,using electrically powered equipment where practical, and avoiding prolonged idling of vehicles and equipment. 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity • of the site (including year-round and seasonal streams, • saltwater, lakes, ponds, or wetlands)? If yes, describe and provide names. If appropriate,state what stream or river it • flows into. Yes. Lake Washington and the Cedar River are within the project area. The old Bryn Mawr treatment plant is adjacent to Lake Washington. The proposed inverted siphon'alignment crosses under the Cedar River. The King County Sensitive Areas Map Folio does not identify any wetlands within the project corridor. 8 Bryn Mawr System Improvements Environmental Checklist • 2) Will the project require any work over, in, or adjacent to the described waters? Construction of the proposed system improvements would require work adjacent to Lake Washington and the Cedar River. No construction would occur within the lake or river. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. 4) Will the,proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. . 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. No. 1 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to groundwater? Give general description,purpose, and approximate quantities if known. Dewatering would be required where the depth of excavation extends below the groundwater table. Dewatering is likely to occur throughout most of the alignment. The anticipated methods of dewatering are sumps and in-trench pumps. Wellpoints may be employed in areas where surface settlement is a concern. Groundwater would be discharged to the sanitary sewer,local storm drainage facilities or to the Cedar River depending upon water volumes and quality. Discharge of dewatering volumes to the sanitary system would require a King County Industrial Waste discharge approval. The Department of Ecology would have to approve discharges to the Cedar River. • • No groundwater withdrawals would occur once construction has been completed. 9. Bryn Mawr System Improvements 1 Environmental Checklist / _ I ' i 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None. - c. Water Runoff(including storm water): I) Describe source of runoff(including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so,describe. Operation of the proposed system improvements will not require storm runoff control as all improvements would be located below ground. Runoff within the project corridor eventually reaches Lake Washington. During project construction the source of site runoff would be - rainfall events. Construction activities would be managed to control' • runoff amount and prevent erosion and sedimentation. See information contained in Section B.1.h. 2) Could waste materials enter ground or surface waters? If so, generally describe. The project does not propose discharging waste material of any kind into ground or surface waters. Construction related material could find its way into ground or surface waters due to accidental spills, mechanical failures or if construction activities deviate from the project construction contract or permit conditions. d. What measures are proposed to reduce or control surface, ground and runoff impacts; if any. Spill prevention and control measures will be included in the project's construction contract specifications. Erosion and sediment control measures are described in Section B.1.h. 4. Plants a.

List any threatened or endangered species known to be on or near the site. A review of the Washington Department of Fish and Wildlife's Priority Habitats and Species database did not identify threatened or endangered • species on or near the project alignment. 'c. Is the site a part of a migration route? The Cedar River contains anadromous fish runs. Species include coho, fall chinook, sockeye, summer and winter steelhead and smelt. , d. ' Proposed measures to enhance wildlife,if any: 11 Bryn Mawr System Improvements • Environmental Checklist. . Ir Construction methods proposed to install the siphon barrel under the Cedar River would eliminate the need for inwater construction thus avoiding adverse effects upon the Cedar River. Coordinate construction activities with those wildlife resource agencies responsible for approval or review of the siphon crossing under the river. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil,woodstove, solar)will be used to meet the project's energy needs? Describe whether it will be used for heating, manufacturing, etc. During construction, fossil fuels would be utilized to power construction vehicles, equipment and haul trucks. Electrical energy would also be used to operate some construction equipment. Operation of the siphon and sewer trunk will not require electrical energy. b. Would your project affect the potential use of solar energy by adjacent properties? No. c. What kind of energy conservation features•are included in the plans for • this proposal? List other proposed measures to reduce or control energy impacts if any: None. 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal.If so, describe: • The only hazardous materials used for project construction activities would be fossil fuels (e.g., diesel and gasoline) used to power vehicles and equipment and various lubricants and solvents. It is possible that inadvertent spills of these substances could result in health hazards. Contaminated groundwater and soil are likely to be encountered during construction within Cedar River Park. Volatile organic compounds have been found in groundwater samples collected within Cedar River Park. King County's Industrial Waste Program has established and enforces discharge limits to regulate the quality and quantity of waste waters discharged to King County's sanitary sewer system. Available groundwater quality data indicate that construction-related dewatering effluent generated during pipeline replacement construction would be suitable for discharge directly to the King County sewer system without pretreatment. Field screening of excavation spoils for visual signs of contamination and for volatile organic vapors would be conducted during construction operations within Cedar River Park. If any suspected material is detected 12 Bryn Mawr System Improvements Environmental Checklist . • during the construction, soil would be subjected to further analytical testing to determine appropriate handling/disposal action. 1) Describe special emergency services that might be required. None. 2) Proposed measures to reduce or control environmental health hazards, if any: Construction of the Bryn Mawr System Improvement project would eliminate sanitary sewage overflows to Lake Washington. This would have a positive effect on public health and beneficial uses of the lake. Occupational Safety and Health Act (OSHA) regulations regarding safety equipment and procedures would be strictly enforced on construction sites. Discharge of trench dewatering volumes to the sanitary sewer system would require an Industrial Waste Discharge authorization from King County. Project construction specifications would include procedures for identification and handling of contaminated soil and groundwater. b. Noise • • 1) What types of noise exist in the area that may affect your project (for example: traffic, equipment, operation, other)? None. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other?) Indicate what hours noise would-come from the site.. Construction activities would result in short-term impacts upon project area noise levels. Construction noise would consist of engine noise, and mechanical and scraping noises associated with the use of heavy construction equipment such as bulldozers, graders, scrapers, loaders and excavators. Construction.noise levels would vary depending on the specific equipment used for a particular activity. Based upon previous construction projects, noise levels could be expected to range from 79 to 88 dBA measured at a distance of 50 feet from the source. • Noise would be limited to the areas of active construction. Hauling activities and workers commuting to and from the job site would contribute to traffic noise. Construction of the various project elements is anticipated to take place between the hours of 7:00 a.m. and 7:00 p.m. on weekdays. • 13 Bryn Mawr System Improvements Environmental Checklist • i� Weekend or evening work is not anticipated, but may be employed in order to minimize or avoid construction related disruptions. Construction noise levels would comply with the applicable regulations of the permitting jurisdiction. Operation of the siphon and pipeline would not generate a discernible noise. 3) Proposed measures to reduce or control noise impacts, if any: • Measures to reduce or control noise impacts during construction "could include the following measures: - use noise attenuation barriers/enclosures around certain equipment; -require mufflers on all gas powered equipment - limit the times of certain construction activities which produce high noise levels; and - encourage the use of electric or hydraulic tools whenever practical. Prior to the start of construction, King County will coordinate construction activities with business operations and residents within the project corridor that may be sensitive to construction related • noise, dust, vibration or traffic. All construction activities would comply with the applicable noise regulations. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? Land use along the proposed siphon and pipeline consists of mobile home/multi family within unincorporated King County; and commercial/public facility, park and industrial within the City of Renton. b. Has the site been used for agriculture? If so, describe. - No. c. Describe any structures on the site: None. • d. Will any structures be demolished? If so,what? Construction of the siphon and pipeline would cross streets, curbs, parking areas,utilities lines, sidewalks and landscaping. e. What is the current zoning classification of the site? Those portions of the alignment within unincorporated King County are zoned residential R-8 and R-48 (8 and 48 dwelling units per acre). The airport and park properties are within Renton's,Public Use (P1)zone. That portion of the alignment along N. 6th Street is zoned Heavy Industrial. 14 Bryn Mawr System Improvements Environmental Checklist • f. What is the current comprehensive plan designation of the site? Areas within unincorporated King County are zoned residential, allowing 4 to 12, and greater than 12 dwelling units per acre. Areas within the City of Renton are zoned Industrial Employment. g. If applicable,what is the current shoreline designation of the site? King County and Renton have designated the shorelines of Lake Washington and Cedar River within the project corridor as Urban. h.

The existing Bryn Mawr trunk consists of a 27- _ r inch diameter reinforced concrete pipe sewer that extends from the Bryn Mawr inverted siphon,located at the north end of the Renton Municipal Airport, to the Eastside Interceptor at the intersection of North Sixth Street and , C Burnett Avenue North. As part of the Bryn Mawr System Improvements Project,the capacity of the sewer will be I, increased to prevent sewage backflow into Lake Washington. The trunk sewer capacity will be increased by replacing the existing Bryn Mawr trunk with a larger diameter reinforced concrete pipe. The section of the sewer to be replaced extends from the East Side Interceptor to the west approximately beneath I North Sixth Street for about 1,400 feet to the intersection of Riverside Drive North and North Sixth Street, where the pipeline alignment turns to the north. The proposed pipeline continues north for about 2,800 feet,where it turns back to the west and crosses beneath the Cedar River and the Renton Airport in a microtunnel: The pipeline I continues to the beginning point of the existing inverted siphon. i1.1 SCOPE OF WORK il,,, The purpose of the geotechnical evaluation is.to determine subsurface conditions along the alignment, to develop N geotechnical engineering parameters, and to provide geotechnical recommendations for design of the project 1 , features.Specifically,our scope of work includes the following: 1j. 1. Perform a review of existing, available geotechnical information for projects completed in the immediate vicinity of the site area. Conduct design level geotechnical explorations in order to 4 develop geotechnical parameters suitable for design. 2. Prepare this draft Geotechnical Design Report that includes: • A description of soil and groundwater conditions anticipated along the alignment, based on existing boring and test pit and explorations completed for this study. • Pipeline design parameters • Recommendations regarding temporary shoring of trench excavations f 1 PACRIM GEOTECHNICAL INC. 'i ;+ DRAFT • Recommendations for pipe support and estimated earth loads. • Recommendations for dewatering and managing groundwater during construction. • Recommendations regarding seismic design considerations. • Microtunnel design parameters including: • Anticipated tunneling ground conditions • Construction considerations - • Temporary access shaft construction considerations • Design recommendations for the permanent access vault at the East Side Interceptor • I 1.2 REPORT ORGANIZATION This report is presented in two general divisions,findings and conclusions: The material contained in the findings portion of the report(chapters 1 through 3)include the introduction,the sources of subsurface data and the general geology picture for the project. The conclusion section of the report contains a description of the specific subsurface conditions expected at the specific project features, and geotechnical recommendations to be used for design and construction of the project features. 1.3 PROJECT DATUM The project datum that is utilized on all design drawings and boring logs contained in this report is the 1929 Mean Sea Level U.S.0 and U.S.G.S, adjusted in 1947 plus 100 feet. For the purposes of this report, the datum will be referred to herein as"Metro datum". 1.4 PRINCIPAL PROJECT FEATURES I; The principal project features will be described in the order of increasing stationing along the alignment. The features can be seen on Figures 3 through 12,which show the plan and profile of the new sewer line. East Side Interceptor Vault: The permanent vault will be constructed to facilitate connection of the new Bryn Mawr Trunk (BMT) to the East Side Interceptor (ESI). The vault will be constructed in Burnett Avenue North at the intersection of the BMT and the ESI. The permanent vault is planned to be about 6 feet by 16 feet in plan dimension, and composed of reinforced, cast-in-place concrete. The 108 inch diameter ESI has an invert elevation of about 103 at the location of the intersection. Therefore, since the ground surface is at about elevation 127, an excavation depth on the order of 24 feet to the ESI invert, and about 26 feet to the foundation level for the vault is expected. Bryn Mawr Pipeline: The BMT pipeline will be a 36-inch-diameter concrete pipe that is installed from the ESI at station 0+00 to the start of the microtunnel at station 42+48.43. The pipe is gravity flow with a slope of 0.001, foot/foot,from an invert elevation of 106.10 at the ESI,to elevation 110.35 at the start of the microtunnel at station 42+48.43. The ground surface slopes generally down from a high at the ESI at about elevation 127, to a low of about 117 near the connection to the microtunnel section. Therefore,trench excavations are expected to range from about 22 feet near the ESI(station 0+00)to about 8 feet near the microtunnel portion(station 42+48.43). The pipe will replace the existing 27-inch-diameter BMT sewer for the majority of its length,and will be installed adjacent to the existing line. 2 PACRIM GEOTECHNICAL INC. t DRAFT Microtunnel: A microtunmel is planned to allow the BMT to pass below the Cedar River and the runways for the Renton Airport. The east access shaft for the microtunnel at pipeline station 42+48.43 will serve as the terminus of the inverted siphon that begins at the west project end at the connection for the current siphon. The inverted siphon pipeline will be 24 inches in diameter, with a minimum slope of 0.008 feet per foot. The microtunnel pipeline 111 grades range from a low at the east access shaft of 92.83 feet at station 42+48.43, to a high of 99.64 at the west access shaft at about station 51+00. Present plans call for the tunnel to be 850 feet long. The current design indicates that the microtunnel will have a clearance of 2 feet below any future dredging limits presently known (elevation 99)for the Cedar River. The microtunnel access shafts will be about 32 feet deep on the east side to the working floor level of the shaft and about 25 feet deep to the working floor level for the west shaft. The total depth of the shafts will depend on the contractor's method of construction and groundwater control. The microtunnel shafts are considered to be temporary and to be designed by the contractor. The shaft on the east side of the Cedar River will,however,have a permanent manhole constructed inside of the shaft once the microtunnel is completed. At present,no intermediate shafts,or access points are envisioned,however they may be required depending on the contractor's equipment. West End of the Siphon: The siphon will continue to the west from the west access shaft for the microtunnel at about station 51+00, to the current start of the siphon. The alignment through the area is not presently known, although a proposed alignment is shown on the figures for this report. 1.5 LIMITATIONS This report was prepared with the plan and profile information that was available at the time of preparation of this draft report. The pipeline alignment west of the west microtunnel access shaft (west of station 51+00) was not considered by the design team to be known enough to complete design level explorations in that area. Non- /6 geotechnical issues, such as property acquisition need to be solidified before explorations are completed. Once a route is known,design level explorations should be completed along the alignment. The extent of soil and groundwater contamination in the vicinity of the connection to the ESI, and how that contamination will affect design and construction will be further defined after a second round of explorations are completed in the area of boring B-7. 2.0 SOURCES OF DATA +� V 2.1 SUBSURFACE EXPLORATIONS h To complete this study we reviewed available geotechnical and environmental subsurface information that was produced for other adjacent projects and for the initial BMT and the ESI. Once data gaps were identified, PacRim Geotechnical Inc.(PGI)completed two rounds of subsurface explorations for the project. Phase I was completed at the approximate locations of the access shafts for the microtunnel to investigate the feasibility of completing a microtunnel below the Cedar River and the Renton Airport. Phase II was completed to fill in gaps in subsurface' data along the microtunnel portion and the BMT pipeline portion of the alignment. Explorations have yet to be completed for the portion of the siphon west of the west microtunnel access shaft. They will be completed later, once the alignment has been chosen. PGI summary boring logs are included in Appendix A. Laboratory test results are presented in Appendix B. Summary boring logs by-others utilized for this study are included in Appendix C. The specific sources of subsurface data,other than PGI completed borings,include: ! _" • "Geotechnical Report, Boeing Storm Drain Interceptor, Renton, Washington", dated March 20, 1997 by Hong West&Associates,Inc. l 'r • "Subsurface Exploration and Geotechnical Engineering Report, Boeing Apron D Expansion, Renton, Washington"dated January 1992 by RZA AGRA,Inc. 3 PACRIM GEOTECHNICAL INC. V DRAFT • Weston borings along Riverside Drive The proposed Boeing Storm Drain Interceptor will be located on the east side of Riverside Drive, and parallel the new BMT for its entire length along Riverside Drive. Several borings were completed for the investigation near the ' alignment of the storm drain. Information from these borings provided adequate subsurface information such that additional borings were not required along Riverside Drive in order to complete this study. In addition, existing subsurface information was utilized for the BMT pipeline along North Sixth Street, from about station 9+00 to station 14+00. This information was developed for Boeing improvements along Apron D. Copies of boring logs for borings drilled adjacent to the sewer alignment are presented in Appendix C. PGI explorations were completed along the pipeline portion of the BMT along North Sixth Street, and for the microtunnel portion of the project. Borings B-1 through B-4 were completed near the access shafts for the microtunnel(B-1 and B-2)and along the tunnel itself at intermediate points(B-3 and B-4). Borings B-5 through B- 7 were completed along North Sixth Street for the pipeline and for the vault planned at the ESI connection. The locations of the borings completed by PGI and by others but used for this study can be found on Figures 3 through 15. 2.2 LABORATORY TESTING Geotechnical laboratory testing was completed on selected samples retained from the borings. Laboratory testing included moisture and density,grain size analyses,and consolidation tests. A detailed description of the laboratory testing program can be found in Appendix B. The results of the laboratory"testing can be found on the boring logs in Appendix A,and in Appendix B. 3.0 GEOLOGY 3.1 REGIONAL GEOLOGY Renton is located in the Puget Lowland, which is a slightly arcuate, convex-eastward basin lying between the Cascade Range on the east and the Olympic Mountains(coastal range)on the west. The basin is open to the north to the Geogian Depression and the Strait of Juan de Fuca,the latter connecting Puget Sound with the Pacific Ocean. Beneath Puget Lowland, non-lithified Quaternary sediments of varying thickness generally unconformably overlie Tertiary bedrock. These sediments are both glacial and non-glacial in origin. ti The Puget Lowland is underlain by a considerable thickness of sediment,and relatively little bedrock is exposed at the surface. Bedrock is exposed only in parts of southeastern Seattle and near Alki Point. The general topography in the Puget Sound region has been formed by the deposition and removal of soil directly or indirectly by glacial ice. Puget Sound sediment was deposited primarily by a series of Pleistocene age(about 2 million to 10,000 ybp [years before present])continental glacial advances that extended into the Puget Lowland. Prior to the most recent Vashon(Fraser)glaciation, floodplain and fluvial sediments ranging from silt and clay to sand and gravel were deposited within the Seattle area during the interglacial Olympia Stade, dated from about 28,000 ybp to 16,000 ybp in the Seattle area. The most recent glacial period is known as the Fraser Glaciation. The last major advance of continental glacial ice, known as the Vashon Stade,began in the Seattle area about 16,000 ybp. During this glaciation,which lasted until about 13,000 ybp,up to several hundred feet of glacially derived soil were deposited within the Puget Sound area. In the Seattle area, this soil typically includes the glacio-lacustrine Lawton Clay, the advance outwash Esperance Sand,Vashon Till,and minor recessional outwash and ice marginal.deposits. 4 '}---' PACRIM GEOTECHNICAL INC. DRAFT At the onset of the Vashon Stade of the Fraser Glaciation, the Puget Lobe, an arm of the continental glacier, advanced south into the Puget Lowland, blocked the Strait of Juan de Fuca, and formed a large pro-glacial lake. Coarser-grained sediment transported by rivers and streams was deposited in deltas near the lowland margin, and finer-grained sediment settled out in the quiet lake water to form the alternating glacio-lacustrine silt, fine sand and clay deposits of the Lawton Clay. As the Vashon continental glacier advanced southward, outwash sand and gravel was deposited by glacial meltwater, creating an outwash plain in front of the advancing ice. The Vashon advance outwash is known as the Esperance.Sand. Eventually, the glacier overrode the outwash plains, consolidating the Esperance Sand, Lawton Clay, and underlying pre-Vashon sediments. Vashon Till was deposited beneath the ice as the continental glaciers advanced. Glacial till is an unsorted to poorly sorted soil mixture composed of clay-to boulder-size particles that were deposited at the base of a glacier. Compaction by the weight of the overlying ice resulted in a concrete-like appearance of unweathered till. Glacially-compacted soil typically has a much greater density than non glacially-compacted soil. Glacial sediments were modified into elongated hills trending in the direction of ice transport, generally north to south in the Seattle area. The glacial ice also smoothed and locally modified pre-existing topography, forming the Duwamish River Valley and Elliott Bay of Puget Sound. Post-glacial modification of the land had a major influence on the project area. Alluvial and lake bed soil deposits were deposited by the ancestral Black River and by Lake Washington in the project area. The Black River was not only the outlet for the lake prior to about 1911; it was also an inlet during periods of flooding, or periods of high tides. Thick sequences of alluvial sand,silt and organic material were deposited during the period prior to 1911. Between 1911 and 1916, the Lake Washington Ship Canal was constructed, linking Lake Washington to Puget ' Sound. This construction resulted in lowering the surface of Lake Washington a nominal 10 feet(Chrzastowski,. 1983)to the level of Lake Union. Before the Lake Washington Ship Canal was completed in the early 1900's,the Black River drained from Lake Washington, and the Cedar River was a tributary to the Black River. The Cedar River flowed into Lake Washington only during periods of high water flow on the Cedar,and high tide conditions. The Black River then flowed westward and into the Green River, where it continued to empty into Puget Sound. After completion of the Ship Canal project, the outlet feeding the Black River was blocked, and the Cedar River was channelized and redirected into Lake Washington. Flow in the Black River effectively ceased except for the drainage originating on the adjacent drift plain highland. When the lake level was lowered about 10 feet, in the northern part of Renton, both the newly exposed lakebed and surrounding freshwater marshes were filled or otherwise modified by development. 3.2 PROJECT GEOLOGY The majority of the site is underlain by alluvial and lakebed deposits overlain by fill soil. The lakebed and alluvial material is believed to have been deposited prior to construction of the Lake Washington Ship Canal, which was completed in 1916. The lakebed and alluvial soil deposits that were encountered in the project vicinity were generally fine grained sand and silt deposits. Interlayering of organic material within the alluvium suggests that the area was also part of the lakeshore, or marsh land that was periodically exposed to flood waters, or seasonal lake level fluctuations. Fill material was encountered also in the project area. It ranged from thin fill layers constructed to support roadways,to thick fill sequences believed to have been deposited to fill in marsh land after the lake level was lowered as a result of the Lake Washington Ship Canal project. The fill consisted of fine grained sand,and was found to be thickest near the Renton Airport. Detailed descriptions of the subsurface conditions will be presented for each project feature in following sections of this report. 5 PACRIM GEOTECHNICAL INC. DRAFT 3.3 HYDROLOGY In the immediate vicinity of the Cedar River and Lake Washington, groundwater levels are dominated by the two large bodies of water. Groundwater levels in explorations completed in the immediate vicinity of the Cedar River were found to be in very good agreement with the water level in the river. Further away from the Cedar River and Lake Washington, groundwater levels were found to be within about 10 feet of the ground surface. Although measurements were not taken to determine the exact amount of influence, it is very likely that the water levels are dominated by the influences of the Cedar River and Lake Washington. I , • 6 PACRIM GEOTECHNICAL INC. DRAFT vi 4.0 CONCLUSIONS AND RECOMMENDATIONS The conclusions and geotechnical recommendations will be presented in the following sections for.individual project features. In order to minimize repetition, expected subsurface conditions at each project feature are presented in this portion of the report,rather than in the first portion of the report. The report is presented in this fashion so that the reader can view the site specific subsurface conditions for each project feature, and the geotechnical recommendations in close proximity to each other. In general,the project,as proposed,is geotechnically feasible if the recommendations provided herein are followed. There are geotechnical aspects of the project, such as soil liquefaction or ground settlement due to microtunneling or dewatering that will likely be unavoidable,or cost prohibitive to mitigate. This report defines the risks associated with the proposed construction, and presents possible mitigation measures for construction related impacts to existing improvements. Following recommendations are presented for the pipelines portion of the project, the microtunnel portion of the project,the access vault at the ESI,and the pipeline west of the microtunnel. 4.1 PIPELINE The BMT pipeline will be a 36-inch-diameter concrete pipe that is installed from the ESI at station 0+00 to the east access shaft of the microtunnel at station 42+48.43. The pipe is gravity flow with a slope of 0.001 feet/foot, from an invert elevation of 106.10 at the ESI,to elevation 110.35 at the start of the microtunnel at station 42+48.43. The ground surface slopes generally down from a high at the ESI at about elevation 127 to a low of about 117 near the connection to the microtunnel section. Therefore,trench excavations are expected to range from about 22 feet near the ESI (station 0+00)to about 8.feet near the microtunnel portion (station 42+48.43). The pipe will replace the existing 27-inch-diameter BMT sewer for the majority of its length, and will be installed adjacent to the existing line. 4.1.1 Anticipated Subsurface Conditions Typical soil conditions adjacent to the alignment consist of surficial fill overlying recent alluvial deposits. The alluvial deposits range from poorly graded sand to clayey,peaty silt. Fill soil ranges from silty sand and gravel to sand. Groundwater was encountered,or measured at depths ranging from about 10 feet below the ground surface to about 5 feet below the ground surface. A more detailed description of the anticipated conditions within the trench is presented in following sections. ' rI Beginning at station 0+00, silty sand and sand, with relatively thin interbeds of soft silt are expected within the trench excavation. As noted on boring log B-7, a slight hydrocarbon odor was noted in the soil samples in the upper 12 feet of the borehole. Further chemical characterization of the soil will be completed later. The pipe foundation should be in alluvial material identified as loose, wet, fine sand interbedded with silty sand. For the most part, soil expected near station 0+00 within the pipeline depth would be either loose or soft, and predominantly fine sand, or silty sand. The groundwater level was measured at between 9 and 10 feet below the ground surface, at about 12 feet above the proposed pipe invert level (pipe at about 21 feet below the ground surface). Of special note in the vicinity of station 0+00 is the water-bearing gravel unit encountered below the pipe = invert at between 28 and 36-1/2 feet below the ground surface, and the organic, clayey,peaty silt unit encountered at'42 feet below the ground surface. The gravel unit was not encountered in any other borings, and is therefore 1 'S believed to be limited in lateral extent. The organic unit was encountered in other explorations completed for this study, and noted in explorations in the vicinity completed by others. It is therefore believed to be more extensive, and based on observation of the samples secured, it should be relatively low in vertical permeability when compared to the sand and gravel units of the alluvium. ' 7 PACRIM GEOTECHNICAL INC. 1 � DRAFT As the excavation proceeds from station 0+00 to the west, the material encountered in the trench, and at the pipe foundation level, should be similar until the trench excavation reaches about station 7+00. From station 7+00 to station 14+00 where the pipeline turns to the north along Riverside Drive, interbedded silt, organic silt, and fine sand are expected to begin at the foundation level of the pipe near station 7+00,and extend up to slightly above the crown of the pipe at about station 8+00 where the anticipated conditions will be about 5 feet of roadway fill underlain by interbedded silt and sand to about the crown of the pipe, and then interbedded organic silt and sandy silt to below the pipe invert. The underlying organic-rich layer encountered at 42 feet in boring B-7 was encountered at 36 feet in B-6,and31 feet in B-5. In borings drilled along the Boeing Storm Drain Interceptor between BMT station 14+00 and 42+48.43, the surficial fill was typically encountered below the roadway to depths varying from 1 foot to 7.5 feet. Thickness of the fill appeared to increase toward the north. Composition of the fill varied from silty fine sand to sand with varying amounts of gravel. Based on blow count information the consistency of the fill varied from loose to medium dense.Alluvial deposits in the same section typically consist of layers of very soft to soft silt/fine sandy silt, - and loose to medium dense silty sand and sand. All of the subsurface explorations reviewed were terminated in the alluvial deposits. In general, the excavation for the new BMT will be completed directly over the existing 27-inch-diameter sewer line,but will extend about 5 feet below the current invert level of that line. Trench excavation depths are expected to vary from about 9 to about 11 feet to the pipe invert. The majority of the material expected in the trench excavation will be backfill of the existing line. Conditions within the sewer trench are anticipated to consist of - Class II backfill material, which was specified as the required backfill material in the original construction drawings. Class II backfill generally consisted of sand and gravel. Trench backfill will only be encountered to the extent that the final alignment follows the current alignment. Below the bottom of the current trunk line trench,and outside of the trench,loose/soft interbedded alluvial sand,silt,and organic silt is expected. r-, ' Groundwater level is estimated based on previous groundwater levels recorded in the area during previous projects and from groundwater levels reported in the Hong West & Associates report for the Boeing Storm Drain Interceptor. Observations during drilling and measurements completed in wells and piezometers by others indicate � that the groundwater level is relatively shallow and is typically encountered between depths of 3 to 5 feet,or about 8 to 6 feet above the pipeline invert. Groundwater levels are expected to vary depending on the season and the water levels of Lake Washington and the Cedar River, and could approach the ground surface during periods of heavy {!l, rain or flooding. 4.1.2 Trench Excavation and Shoring Trench excavation depths to the pipe invert will vary from 8-1/5 feet at about station 41+00 to 22 feet at station 0+00. Total excavation depths will be greater by the amount of pipe bedding, and foundation treatment (if required). Conventional hydraulic excavating equipment designed to dig to the required depths should have sufficient power to excavate the trench throughout the alignment in the anticipated soil conditions. Dewatering and temporary shoring will be required. Dewatering recommendations are discussed in a following section. The design of trench support systems, and the actual trench configurations should be the responsibility of the Contractor and should conform to the safety requirements of all local,state,and federal codes.All open cuts should be carefully monitored during excavation to detect any evidence of instability. If instability is detected, the contractor should immediately change or adjust their temporary shoring,or dewatering methods to maintain a stable trench. Prior to construction, the contractor should prepare a shoring and excavation plan for the review for the project engineer prior to construction. 4.1.2.1 Trench Retention In order to minimize ground movement adjacent to the trench, and to minimize the impacts to utilities and other surface improvements in the vicinity of the trench,trench retention is recommended. The retention method chosen should also consider the type of dewatering that is being completed for that portion of the trench. Since the trench retention is temporary, it should be contractor designed. This section presents our recommendations for trench rti—1 8 1, O PACRIM GEOTECHNICAL INC. DRAFT retention and provides parameters for lateral support design. All temporary shoring design is the responsibility of the Contractor. The contractor should choose their retention method within the constraints presented in this report. In general, properly designed sheet piles and sheet pile bracing systems will result in less movement of the surrounding soils than utilizing a trench box for shoring. This is because the trench box requires that the excavation be completed first,and remain open long enough to pull the trench box into place. Loose soil then caves in on the sides of the trench box. Ground movement can be reduced by utilizing steel sheets placed between the trench box sides-and the soil. Sheet piles are driven in place prior to the excavation. As the excavation proceeds, interior bracing is installed. Once the pipeline is installed and backfilled,the steel sheet piles are removed. Sheet piles are, considerably more expensive than a trench box, and will likely result in slower construction. However, sheetpiles can be used as a partial groundwater cutoff, while full exterior dewatering to two feet below the bottom of the expected excavation is required for a trench box. Design of temporary shoring should consider the groundwater control method utilized, and how dewatering will affect lateral earth pressures. For instance, if sheetpiles are utilized, and pumping is completed within the sheet piles, lateral earth pressures should consider hydrostatic pressures on the outside of the sheet piles, and a possible reduction in passive resistance on the interior of the sheets if upward seepage pressure is present on the soil on the interior of the sheet piles. If the area is dewatered,lateral earth pressures need to consider the full weight of the soil, but need not include hydrostatic pressures. Lateral earth pressures should be developed using the soil parameters presented in Table 1, or the contractor may develop their own design parameters based on the subsurface information.

Once the excavation is away from the connection vault for the ESI, there are no major utilities,or structures near enough to the trench to require other than standard trench support with a trench box,and full dewatering. The excavation,however, is greater than 21 feet deep so stacked trench boxes, or steel sheet piles may be more appropriate. Dewatering will be required. It is likely that the pipe will be installed by jack and bore from about station 1+00 to 4+00 to cross Logan Street, so special shoring will be required for the access pits. Additional recommendations for jacking and boring are presented in following sections. In the event that the trench box system is not found adequate to support the soil and reduce ground movement, steel sheet piles with interior braces should be installed. If settlement sensitive structures, or utilities are found in the vicinity, or if settlement should be kept to a minimum,sheet piles should be installed in the areas of concern. Station 8+00 to 14+00. In order to reduce the impacts of ground settlement on surrounding structures adjacent to the roadway, sheet piles and minimum dewatering are recommended in this section. In order to provide an adequate groundwater cutoff, steel sheet piles may need to be longer than the length required for shoring purposes only. For this reason,trench shoring should consider the dewatering method chosen. Dewatering requirements are addressed in another section of this report. Station 14+00 to 42+48.43. The proposed Boeing Storm Drain Interceptor will be installed parallel to the BMT ._ sewer alignment,and within 8 to 10 feet of the BMT. The Boeing Storm Drain Interceptor(SDI) is planned to be about 6 feet above the invert of the.BMT near station 14+00, and transition to about 1 to 2 feet below the invert of 9 PACRIM GEOTECHNICAL INC. • DRAFT the BMT near station 42+48.43. At this point, it is uncertain which of the two will be constructed first, or if they will be constructed at the same time. If the Boeing SDI is constructed prior to the BMT,special care will need to be taken to reduce ground movement,and hence damage to the newly constructed SDI. If the SDI is constructed after the BMT,the contractor will not have to be as careful;however, other utilities and surface improvements are in the area. . 4.1.3 Dewatering Since the bottom of the trench will be 10 to 15 feet below the current groundwater levels,temporary construction dewatering will be required. The alluvial deposits are expected to be relatively permeable, and substantial groundwater inflow will occur if the excavation extends over 1 to 2 feet below the groundwater level. Groundwater seepage will tend to destabilize excavation slopes and increase lateral loads on shoring systems. In addition, groundwater flowing into the excavation can cause sand boils, or heaving at thebottom of the excavation, which will compromise foundation conditions. I ; The goals of dewatering are first,to help maintain a stable bottom over which the structure or pipeline can be safely installed;second,to stabilize the sides of the excavation;and third,to keep the excavation free from water. Bottom stability is needed regardless of the method of retaining the sides of the excavation. Proper dewatering is critical to . an open excavation with sloped sides, and important to a braced excavation with timber lagging; in the latter case, uncontrolled seepage may wash material through the lagging. Steel sheeting requires dewatering only to reduce the lateral pressures and maintain a stable bottom. It may be cost-effective in some areas to use steel sheeting and avoid - the necessity for area dewatering. In that case,the sheets must penetrate to an adequate depth and/or the bottom of the excavation should be dewatered to prevent bottom heave. The Contractor should dewater all excavations, including relief of excess hydrostatic head,to a depth of at least 2 feet below the deepest foundation level to reduce , subgrade disturbance of moisture sensitive soil and to provide a firm base for placing and compacting backfill. Soil deposits anticipated along the alignment are variable,ranging from sand to silt. Consequently,any dewatering system should be planned to effectively cope with varying soil conditions. Initial flows may be significantly higher than steady state flows that will occur once the desired drawdown is achieved. Standby capacity should be available to maintain the groundwater table below critical levels in case of a pump or power failure. Methods of dewatering include sump pumping from an excavation(where there is no stability problem), deep wells,wellpoints,jet-eductor• - wellpoints and subsurface drains. Any or all of these may be appropriate for the structures along the alignment depending on specific conditions. In the use of any dewatering methods, care must be taken to provide the correct filtering(packing)around each dewatering unit to prevent the migration of fines from the ground. Silt and fine sand are the materials most susceptible to being moved by water flow. Discharge from the pumps must be monitored; if significant amounts of fines are being pumped or if the flows markedly decrease,the Contractor should identify the cause of the problem and implement corrective measures. Typical deep wells are 1 to 2 feet in diameter and are limited in depth only by the size of pump. The amount of jdrawdown that a deep well can achieve is a function of the hydraulic properties of the soil,the location of recharge sources,the spacing and depth of the wells,and the pump size. The screen slot size for dewatering wells will vary according to the grain size of the soil in the dewatered zone. Improper slot sizing may cause removal or piping of fines out of the soil and could result in settlement. To the extent practical, given the Contractor's working constraints,the wells should be installed at a uniform spacing as close as possible to the excavation. If a body of surface water is present near the excavation,considerations should be given to placing at least one well on that side of the excavation. Deep wells may be appropriate in the vicinity of the vault at the ESI connection. The Contractor should be required to submit a detailed dewatering plan two weeks in advance of installation. If the initial dewatering efforts are inadequate,the Contractor should be prepared to install additional wells or wellpoints. II The Contractor may terminate trench dewatering after backfilling has progressed at least 200 feet past a dewatering well: All dewatering wells should be abandoned according to the regulations set forth in the Washington State Department of Ecology 173-160 WAC. A conventional wellpoint system consists of one or more stages of wellpoints having 1-1/2-or 2-inch-diameter riser �_. pipes, installed on a line or ring at spacings generally between 3 and 6 feet. The risers are connected to a common 10 y - PACRIM GEOTECHNICAL INC. f DRAFT header pumped with one or more wellpoint pumps. Conventional vacuum wellpoints are limited to about 15 to 17 feet of lift. This amount is dependent on the vacuum system,the barometric pressure and the friction losses within the wellpoint system. Higher lifts can be obtained by installing two or more stages of wellpoints with each lifting about 15. feet. The water is pumped from the collection manifold to the disposal area. Jet-eductor wellpoints consist of a wellpoint screen attached to a jet-eductor installed at the end of double riser pipes, a pressure pipe to supply the jet-eductor pump,and another pipe for the discharge from the eductor pump. This type of system is able to lower the groundwater table as much as 100 feet from the top of the excavation. It is limited in useto soil with relatively low permeability and low groundwater flows.. I Extended dewatering could result in a lowering of the groundwater table over a large area, which could cause settlement of the underlying compressible alluvial soils. The amount of settlement and its lateral extent would depend on the amount of change in water level, the length of time the water level is lowered, and the compressibility,thickness and permeability of the underlying soils. Soils with higher permeability,such as sand and gravel will impact a larger area when compared to finer grained soil such as silt. Prolonged dewatering in sand and gravel could result in a cone of depression that reaches up to several hundred feet away from the excavation. Fine grained silt and fine sand would result in a cone of depression that would extend away from the excavation on the order of 50 feet. . Impacts of dewatering can be alleviated by selecting appropriate shoring methods. In comparison to open-cut } excavations,dewatering within a sheet pile enclosed excavation with sufficient sheet pile embedment acting as cut- off wall to groundwater flow will result in less groundwater inflow and drawdown over a smaller area. Since dewatering will likely impact the Apron D area south of the alignment from station 8+00 to about 14+00,sheet piles should be installed in this area so that the impacts of dewatering are minimized. Dewatering should take place with wells installed within the sheet piles, so that the lateral extent of the dewatering effort can be reduced. Alternatively,the contractor may try to dewater outside of the excavation using well points,and monitor settlement f^ ! at the north and south property lines. The extent of dewatering-related groundwater drawdown should be monitored during construction to minimize the potential for settlement damage. A contingency should be provided for installation of recharge wells should the dewatering system result in significant lowering of groundwater levels beneath existing structures and pavements. 4.1.4 Ground Movements Ground movement, both vertical and horizontal, will occur due to trenching activities. The amount of ground movement will greatly depend on the method of trench support, quality of workmanship and ground conditions. I Excessive ground movement can occur as a result of poor shoring construction, improper dewatering design and installation, and lack of monitoring to detect problems. The estimated ground movements presented in this report assume good workmanship by the Contractor and they assume that the ground conditions encountered during construction are in general accordance with our interpretations. • Ground surface settlement and the zone of ground movement adjacent to the trench excavations will generally be distributed within a zone above a line running from the bottom of the excavation up to the ground surface at a slope of I-1/2H:IV(Horizontal to Vertical). Utilities or structures that are within a zone of influence, or on the ground surface above the zone of influence may be affected by ground movement. Ground performance will be strongly dependent on the Contractor's method and sequence of construction. Good construction workmanship should produce smaller zones of influence and magnitudes of ground movement. Horizontal ground movement immediately adjacent to the excavation should be approximately one-half to one times the estimated vertical settlement. Settlement may also occur over larger areas because of consolidation of compressible soil by dewatering. A discussion of dewatering impacts is presented in another section of this report. Avoidable settlement may occur near the excavations as a result of loss of ground by either removal of fines through improperly constructed wells or wellpoints, or by piping or boils in the excavation walls and bottom. Loss of ground should be preventable by proper design and operation of the dewatering system. Additional settlement can occur as a result of poor construction practices during the temporary shoring installation. The amount of additional ground movements will depend on the shoring system used and the Contractor's method of construction. 1I PACRIM GEOTECHNICAL INC. DRAFT Unavoidable settlement as the result of trenching operations should be in the range of the values presented in Table 2. Horizontal ground movements are expected to be in the range of to 1 times the vertical movements.

The excavation bottom may also become disturbed during installation due to construction activities. If soft or loose soil is encountered, or the excavation bottom becomes disturbed, it should be stabilized by overexcavating to firm or medium dense soil or to a maximum depth of 2 feet. A geotextile may be required in some areas to stabilize soft soil in the overexcavated trench bottom. The excavated material should be replaced with material meeting the gradation requirements of Section 9-03.17 of the 1994 WSDOT/APWA Standard Specifications. Foundation material should be thoroughly compacted to provide a dense and unyielding surface. . Uniform support of the pipe should be provided by a minimum of 6 inches of bedding material (below the pipe) meeting the gradation requirements of Section 9-03.15 of the 1994 WSDOT/APWA Standard Specifications. Controlled density fill (CDF) with a minimum compressive.strength of 100 pounds per square inch (psi) may be used as bedding material and should be placed to springline elevation. Granular bedding material should extend to the springline level of the pipe. 4.1.6 Trench Backfill and Compaction Requirements Backfill for pipes should consist of suitable native material, as described below, or clean, imported granular • material. Beneath pavements and up to 2 feet above the crown of the pipe, the backfill should consist of clean; imported granular material meeting gradation requirements of Section 9-03.19 of the 1994 WSDOT/APWA Standard Specifications. In unimproved areas that can tolerate up to about one-half to one foot of long-term settlement, the native soil could be used as backfill from the ground surface to a depth of 2 feet above the pipe crown. The initial backfill around and 6 inches over the crown of the pipe should consist of material meeting the requirements in Section 9-03.15 (bedding material for rigid pipes) WSDOT/APWA Standard Specifications. The Contractor should place this initial backfill in lifts not exceeding 6 inches thickness and carefully work it under the . haunches of the pipe by slicing with a shovel,by vibrating,or by other approved methods. Initial backfill should be thoroughly tamped to provide suitable lateral support of the pipe. Heavy vibratory equipment should not be used. The first lift of backfill above the pipe crown should not be compacted until the backfill has been placed to a height of 2 feet above the crown of the pipe. Subsequent lifts should be placed in lifts not exceeding 8 inches, loose measure. Trench backfill should be compacted to at _least 90 percent of the soil's maximum dry density as determined by the ASTM D-1557 test procedure. Beneath pavement areas the.top 3 feet of backfill should be compacted to at least 95 percent of the soil's maximum dry density using ASTM D-1557 as a standard. 12 PACRINI GEOTECHNICAL INC. DRAFT 4.1.6.1 Reusability of Native Soils Suitable soil for backfill above the initial pipe backfill should consist of clean, granular material that is free of organic and other deleterious material. It should have a moisture content that will allow compaction of the material to the required standards, and result in a non-yielding backfill. It is expected that the majority of the alluvial material excavated from the trench from station 0+00 to station 14+00 will be unsuitable due to high silt and moisture content. Between stations 14+00 and 42+48.43, excavation spoils are expected to consist largely of the Class II backfill specified in the original construction drawings for the BMT in this area. This material is anticipated to consist of sand and gravel fill. There may be a small amount of suitable alluvial material,however, since the alluvium is interlayered with silt,the contractor will need to take care not to mix up the suitable material j-- with unsuitable material. The fill layer encountered in the upper 4 to 5 feet of the borings appears to be suitable for use as backfill provided that the contractor does not mix the sand and gravel with fine grained material from lower in the soil profile. The excavation spoils may be reusable for back fill provided they are free of organics, have a• fines content less than 5 percent,and can be moisture conditioned to within+2 percent of the optimum moisture as determined by ASTM D 1557. During the initial construction activities,the excavation spoils should be evaluated on a daily basis to determine whether they are reusable as backfill. 4.1.6.2 Imported Backfill Imported trench backfill material should consist of sand,bank-run or river-run gravel which meets the requirements.. of Section 9-03..19,Bank Run Gravel for Trench Backfill,of the 1994 WSDOT/APWA Standard Specifications. If backfill is going to be placed in wet weather,the amount of fines(material less than the US#200 sieve)should be maintained less than 5 percent. Backfill within 1 foot of the road way surface should consist of 1 1/4-inch minus crushed rock that meets the requirements of,Section 9-03.9(3), Base Course Crushed Surfacing, of the 1994 WSDOT/APWA Standard Specifications. • 4.1.7 Pipe Loads The soil loads on buried pipe depend on the type and weight of the soil,the type and size of pipe,the depth of the pipe, and the width of the trench. The critical pipe loading will occur when the backfill is dewatered and the full soil weight is applied to the pipe. The vertical overburden (soil) loads on the pipes may be estimated using the design method presented in Gravity Sanitary Sewer Design and Construction, ASCE Manual on Engineering Practice No. 60, (ASCE, 1982) and the soil parameters listed in Table 3. For jacked pipes, the controlling pipe design loads will likely include the magnitude of thrust force during jacking and external fluid pressure such as hydrostatic groundwater,tunneling machine face pressure,bentonite slurry, and any annular fluid grouting that will be done outside the pipe or pipe casing. Loading,such as from vehicle traffic or railroad traffic,should be added to the soil loads. It is anticipated that backfill soil will,in general,consist of granular material.

This report recommends that King County design its facilities for a Lower Level Earthquake (LLE) and an Upper Level Earthquake(ULE). The LLE is defined as an earthquake having a 50 percent probability of being exceeded in a 50-year period and corresponds to a'mean recurrence interval of 72 years. The ULE is defined as an 13 PACRIM GEOTECHNICAL INC. I • • DRAFT earthquake having a 10 percent probability of being exceeded in a 50-year period, which corresponds to a mean recurrence interval of 475 years. The intent of these criteria is that 100 percent of facilities should remain functional and minimal structural damage may occur during the Lower Level Earthquake(LLE). During the ULE, 75 percent of facilities should remain functional, and there should not be any structural collapses. The report further states that, for areas determined to be susceptible to liquefaction, all pipeline designs should consider mitigation of liquefaction, lateral spread, and consolidation susceptibility. A cost benefit analysis should then be performed to decide if the design should be non-mitigated,or mitigated design. In accordance with the King County's design philosophy,we have based our analyses on a seismic risk level of 10 percent probability of exceedence in a 50-year period(mean recurrence interval of 475 years)for the ULE and a 50 percent probability of exceedence in a 50-year period(mean recurrence interval of 72 years) for the LLE. A table in the Kennedy/Jenks report presents ground accelerations for the LLE and ULE events for different King County facilities,including the Bryn Mawr/Boeing Renton Trunks,and for the ESI. The stated values are 0.23g and 0.35g (percentage of gravity)for the LLE and ULE,respectively. 4.1.8.1 Liquefaction Loose alluvial and fill soil, consisting of sand and silty sand,within about 10 to 40 feet of the ground surface, and below the groundwater table have a potential for strength loss and liquefaction during a seismic event. The characteristics of liquefaction-prone soil include: (1)uniform grain size,(2)little or no coarse sand-or gravel-sized particles, (3) low density relative to the maximum density of the material, (4) no plasticity, (5) inorganic, and (6) saturated. During a seismic event, ground shaking causes the build-up of excess pore water pressure and decrease in soil strength within the liquefaction-prone soil. With sufficient intensity and duration of ground shaking, the porewater pressure becomes equal to or greater than the overburden pressure, and the soil loses all strength or "liquefies". The potential damage to the pipeline or structure will depend on the horizontal and vertical extent of liquefiable materials. Liquefaction below a pipeline could cause damage because of increased uplift pressure from upwelling groundwater or from excessive settlement due to consolidation of the liquefiable soil. Structures may be damaged by loss of foundation support during liquefaction,which may lead to tilting or by settlement due to the consolidation of the soil after liquefaction. Available methods to mitigate the liquefaction potential include in-place densification of the liquefaction-prone soil by means such as vibroflotation,stone columns or compaction piles;pile support of the pipeline and/or structures in liquefiable areas;or by overexcavation and replacement where feasible. The alluvial and fill soil observed in borings and inferred from the cone penetrometer probes completed in the project area possess many characteristics of liquefaction-prone soil. Analyses (Seed et al., 1985) were performed on widely spaced borehole SPT tests to determine the soil zones at each exploration location that would liquefy during the LLE or ULE design events. Due to the varying depositional environments, the thickness and lateral extent of liquefaction-prone soil varied significantly between each exploration. Therefore, we have qualitatively assessed the risks of liquefaction damage to the pipeline and/or structures based on our interpretation of subsurface conditions between explorations and our evaluation of the spatial distribution of liquefiable soil. Table 4 presents the results of our liquefaction evaluation at each boring location for the LLE and the ULE. 14 PACRIM GEOTECHNICAL INC.

The samples were not taken in accordance with any environmental sampling protocol, so quantitative analysis was not possible. However, chemical analysis in the King County lab identified diesel and kerosene contamination in the samples. No unusual odor was detected in samples below 7-1/2 feet in depth. In order to define the contaminant levels, and if contamination will impact construction, additional explorations are necessary. 4.1.10 Jack and Bore Installation We understand that pipeline installation by jack and bore is being considered from station 1+00 to 4+00, below Logan Avenue. This is being considered to minimize the impacts of construction on traffic. In this vicinity, the pipeline invert varies from about 21 feet to 20 feet below the ground surface, and about 10 feet below the groundwater level. Jack and bore installation will require dewatered ground conditions for the entire length of the jacked section. • Resistance to pipe jacking will depend on the ground conditions,methods of construction,and the type of tunneling equipment selected for the work. Factors that may be considered to estimate pipe jacking resistance include: details of construction methods such as degree of overcut,manner in which the machine face pressure is controlled, how the soil cuttings are removed, and the effectiveness of bentonite lubrication along the pipe length behind the tunneling machine or tunnel face. Therefore, resistance to pipe jacking cannot be estimated based only on in-situ soil properties. Pipe resistance to jacking should be estimated based on the Contractor's experience in similar subsurface conditions,construction method,and type of tunneling equipment. 15 PACRIM GEOTECHNICAL INC. DRAFT Passive resistance of the soil in the walls of the jacking access pit will be utilized to develop the necessary jacking thrust reaction to overcome the frictional resistance developed along the pipe. The amount of soil resistance will increase as the reaction block is displaced into the soil surrounding the jacking pit. The structural capacity of the jacking pit to accommodate lateral displacements will control the selection of allowable passive soil resistance. The jacked pipe will be installed in alluvial deposits. Subsurface conditions from borings B-6 and B-7 were utilized to provide the expected soil and groundwater conditions. The alluvial soil in the borings at the depth of the pipeline are expected to be loose to medium dense, interbedded fine to medium sand, silty sand, and silt. Occasional scattered organics, and wood chips were encountered. Although not encountered, larger pieces of wood could be encountered,and thecontractor should be prepared to remove logs. Jack and bore methods require fully dewatered subsurface conditions along the entire length of the jacked pipe. Passive resistance of the soil at the jacking pit will be utilized to develop the necessary reaction to overcome the pipe-soil frictional resistance. The available passive resistance may be computed using the equivalent fluid densities given in Table 5. It should be noted that the values in Table 5 are ultimate passive values with no safety factor applied. The designer should apply appropriate safety factors as dictated by their design.

The east access shaft for the microtunnel at pipeline station 42+48.43 will serve as the terminus of the inverted siphon that begins at the west project end,station 59+14.25. The inverted siphon will be 24 inches in diameter,with a minimum slope of 0.008 feet per foot. The microtunnel pipeline grades range from a low at the east access shaft of 92.83 feet at station 42+48.43,to a high of 99.64 at the west access shaft at about station 51+00. Present plans call for the tunnel to be 850 feet long. The current design indicates that the microtunnel will have a clearance of 2 feet below any future dredging limits presently known (elevation 99) for the Cedar River. The microtunnel access shafts will be about 32 feet deep on the east side to the working floor level(about 3 feet below the pipeline invert)of the shaft and about 25 feet deep to the working floor level for the west shaft. The total depth of the shafts will depend on the contractor's method of construction and groundwater control. The microtunnel shafts are considered to be temporary and to be designed by the contractor. The shaft on the east side of the Cedar River will,however,have a permanent manhole constructed inside of the shaft once the microtunnel is completed. At present,no intermediate shafts,or access points are envisioned,however they may be required depending on the contractor's equipment. 4.2.1 Access Shafts The access shafts are temporary structures that are required to complete the microtunnel construction across the Cedar River and Renton Airport. The shafts will be contractor designed,with the exception of the manhole that will be constructed in the east shaft once the microtunnel is completed. 16 PACRINI GEOTECHNICAL INC. DRAFT 4.2.1.1 Anticipated Subsurface Conditions Expected subsurface conditions at the east access shaft were developed based on exploration B-2, completed for this study. The east shaft will encounter about 4 feet of sandy gravel fill over alluvial soil to the expected depth of the shaft. The alluvial soil consists of medium dense silty sand from below the fill at 4 feet to a depth of 11-1/2 feet. Underlying the silty sand and continuing to a depth of 27-1/2 feet,loose to medium dense fine to medium sand,with occasional scattered gravel is expected. Between depths of 27-1/2 and 50 feet, soft organic silt with scattered interbeds of fine sand is expected. Dense sandy gravel was encountered from 50 feet to 54 feet, the total depth explored. Groundwater was measured at a depth of 5 feet shortly after the exploration was completed in 1995. The groundwater level is expected to fluctuate with the level of the Cedar River and Lake Washington. Expected subsurface conditions at the proposed location of the west access shaft were developed based on exploration B-1, completed for this study. Medium dense silty sand with some gravel fill is expected from the ground surface to a depth of 5-1/2 feet. Below the fill,medium dense,fine to medium sand was encountered in the boring to a depth of 10 feet. From a depth of 10 feet to 20 feet,loose/soft sandy,clayey silt was encountered. From 20 feet to 45 feet, loose silty sand is expected, underlain by loose sandy silt to the depth explored (54 feet). The. groundwater level was measured at about 5 feet below the ground surface. 4.2.1.2. Construction Considerations Since the shafts are considered temporary structures, they will be contractor designed. The purpose of the access shaft shoring will be to resist the lateral earth and groundwater pressures. The access shaft will also play an important part in the groundwater control program. Given the close proximity of the shafts to the Cedar River,and the relatively high permeability of the sandy portions of the interlayered alluvial soil, exterior dewatering is not recommended. The shaft could be constructed by using relatively water tight sheet piles to provide both a groundwater cutoff and resistance to lateral earth and groundwater pressures. The sheet piles should penetrate deep, enough to maintain a safe foundation condition within the shaft. It is recommended that the contractor keep the shaft dewatered to at least 2 feet below the floor level of the shaft,and possibly deeper,if required for shaft stability. A dewatering well installed inside of the sheet pile system may be appropriate,however,the well should not extend below the sheet pile tips in order to minimize the influence of dewatering outside of the shaft. If the shoring is completed in this manner, shaft design should consider groundwater pressures as well as earth pressures on the shoring. The contractor should use the soil properties provided in Table 6, or develop their own using the subsurface information presented herein.

DRAFT 4.2.2 Microtunnel The 24-inch diameter siphon will be installed below the Renton Airport and Cedar River by microtunnel. Present plans are for the microtunnel to extend from station 42+48.43 on the east side of the Cedar River,to about station 51+00 on the west side of the Renton Airport,of a total length of about 850 feet. At this time,there are no planned locations for intermediate access shafts. However, the contractor should decide during the bidding process if an intermediate shaft will be required. If access can be obtained from the City of Renton, a possible shaft location would be between the Renton Airport runway and the west bank of the Cedar River. Given the expected subsurface conditions at the microtunnel,a microtunneling machine capable of full face support with minimal soil loss is required. The machine should be capable of balancing the soil and groundwater pressures for a tunnel up to about 30 feet deep in loose sandy material, and with about 25 feet(-11 pounds per square inch [psi])groundwater pressure. 4.2.2.1 Expected Subsurface Conditions Starting at station 42+48.43,the microtunnel, at its present location,will be in a mixed face condition of sand over silt and organic silt. At the microtunnel progresses to the west,the entire face will be loose, fine to medium sand, with silty interbeds by station 46+00. Between borings B-3 (station 46+00) to B-4 (station 4 (station 49+00), conditions will change from sand to interbedded silt, fine sand and wood chips/organics. The tunnel is expected to be in the same ground conditions from station 49+00 to the west access shaft at station 51+00. The contractor should expect some wood debris and wood chips to be encountered in the alluvial soil deposit at the tunnel level. Although not encountered in the borings, larger pieces of wood could also be encountered since the area was once near the shore of Lake Washington. The alluvial deposit appears to be of relatively low depositional energy(predominantly fine grained sand and silt), and therefore the likelihood of boulders is low. However, since the area was also exposed to occasional flood waters from the Black River, there is a small possibility of encountering a boulder. It should also be noted that what appears to be a cantilever wood pile and wood lagging retaining wall presently exists on both sides of the Cedar River in the vicinity of the crossing. No design or construction records of the retaining walls(bulkheads)could be found at the time of this study. Visual observations indicate that they do not have a deadman system for anchorage, so the walls are likely cantilever. The wood piles are about 12 inches in diameter, and about 5 feet on center. Since the retained height is on the order of 5 feet,the total depth of the piles is probably on the order of 15 to 20 feet, which would put the pile tips slightly above the tunnel crown. The pile depth should be verified prior to construction to make sure there will be no interference,or alternatively,the piles that are on the alignment should be pulled,and an alternate source of retention utilized. 4.2.2.2 Pipe Loads Since the soil is loose and granular,pipe loads should be calculated using the entire soil column over the pipe. The loose nature of the soil will likely preclude any soil arching above_the pipe. The vertical overburden(soil)loads on the pipes may be estimated using the design method presented in Gravity Sanitary Sewer Design and Construction, ASCE Manual on Engineering Practice No.60,(ASCE, 1982)and the soil parameters listed in Table 7. For jacked pipes, such as the microtunnel pipe, the controlling pipe design loads will likely include the magnitude of thrust force during jacking and external fluid pressure such as hydrostatic groundwater,tunneling machine face pressure, bentonite slurry,and any annular fluid grouting that will be done outside the pipe or pipe casing. The design should consider these loads in excess of the soil loads to determine the appropriate pipe design. Loading, such as from vehicle traffic or railroad traffic,should be added to the soil loads. • Table 7-Soil Parameters for Microtunnel Pipe Loads Parameter Silt/Sand Moist Unit Weight 120 Rankine Earth Pressure Coefficient(active) 0.36 --- Angle of Internal Friction(4) 28° Friction Angle against concrete pipe 190 18 PACRIM GEOTECHNICAL INC. ,— DRAFT 4.2.2.3 Liquefaction As previously stated, liquefaction is expected along the microtunnel alignment, especially near B-3 between the Renton Airport runway and the Cedar River. Liquefaction caused by ground shaking is likely to have two affects on the pipeline. Those are: an upward buoyant force during the time that the surrounding soil looses its internal strength due to an increase in the pore water pressure; and downward soil forces on the pipeline once the pore pressures drain and the surrounding soil settles due to rearrangement of the existing relatively loose soil structure. Pipeline buoyancy is likely not a concern since this portion of the pipeline is a siphon,and will likely remain full of water during most of its design life. Settlement of the pipeline after soil liquefaction will likely occur after a design level earthquake if the soil near the pipeline remains in its natural state. Settlement will likely occur over the majority of the microtunnel portion of the pipeline. The amount of settlement will vary, and will likely be the most in the vicinity of boring B-3, where about 12 to 15 feet of loose, relatively clean sand was encountered below the pipeline invert. We expect that up to about 4 to 6 inches of settlement could occur below the pipeline from about station 44+50 to station 47+00. Other portions of the pipeline could be subject to settlement in the range of 0 to 2 inches. The settlement will occur over a relatively large area,so relatively small differential settlements are expected,until the pipeline reaches the shaft locations. 4.2.3 Ground Movement . Unavoidable ground movement is expected to occur from shaft construction, and from microtunneling operations. Avoidable ground movement could occur from improper shaft design and construction, and improper dewatering design and implementation. Ground surface monitoring points should be established around the shafts, especially on settlement sensitive structures or utilities,prior to construction, so that possible problems can be identified and remedied early in construction. Ground movement from properly constructed access shafts should be in the range of 2 to 3 inches immediately adjacent to the shaft, and 1 to.2 inches about 15 feet away from the shaft. Underground utilities, or above ground improvements located in a zone of influence identified by a 1 H:1 V sloping line beginning a the base of the excavation and extending up to the ground surface will be subject to ground movement due to construction of the shafts. Horizontal ground movement is expected to be in the range of%2 to%of the vertical ground settlement. Surface settlement is expected to occur due to microtunneling operations: The amount of settlement will depend, largely,on the care taken by the contractor,and their ability to control the face of the microtunnel so that soil loss is minimized. Ground movement can also occur if improper (too high) grout pressures are used at the microtunnel face, or along the pipeline to reduce friction. Ground heave can occur if pressures are too high for the soil and groundwater condition present. If proper care is taken,the ground surface settlement should be in the range of to inch. The settlement trough will be about 25 to 35 feet wide at the ground surface,with the maximum settlement occurring at the center of the trough. 4.2.4 Vault at East Side Interceptor A permanent access vault constructed to facilitate connection of the new BMT to the ESI. The vault will be constructed in Burnett Avenue North at the intersection of the BMT and the ESI. The permanent vault is planned to be about 6 feet by 16 feet in plan dimension, and composed of reinforced, cast-in-place concrete. The 108 inch diameter ESI has an invert elevation of about 103 at the location of the intersection. Therefore, since the ground surface is at about elevation 127,an excavation depth on the order of 24 feet to the ESI invert,and about 26 feet to the foundation level for the vault is expected. Design issues related to vault design are presented in following sections,as well as construction issues related to settlement and dewatering. 4.2.4.1 Design Issues The design issues related to the permanent vault are the design lateral earth pressures,the allowable foundation soil bearing pressure, and buoyancy of the vault. Since the walls of the vault will not be free to deflect,they should be designed using the at-rest lateral earth soil pressures and groundwater pressures resulting from the design groundwater level. The groundwater level near the vault was measured at about 10 feet below the ground surface 19 PACRIM GEOTECHNICAL INC. DRAFT during our explorations at the site. Since the explorations were completed in the summertime, wintertime groundwater levels are expected to be higher than measured. A design groundwater level at 5 feet below the ground surface is recommended for design. The at-rest lateral earth pressures for design should be modeled by using an equivalent fluid weight of 50 pcf - (pounds per cubic foot) above the design groundwater level, and 25 pcf below the design groundwater level. An allowable soil bearing pressure at the foundation level of 1,500 psf, in excess of the present vertical soil pressure should be used for design. Foundation preparation should consist of overexcavation of a minimum of 1 foot below the planned foundation level, and placement of 1 foot of 1-1/2 inch washed crushed rock. Prior to placing the crushed rock, a geotextile separation fabric (Marafi 140N or approved equivalent) should be placed over the exposed subgrade. The crushed rock will provide'a working foundation that will allow construction of the vault with a minimum of disturbance. The vault should be designed to resist buoyancy from the design groundwater level. Resistance to buoyancy should be gained by the weight of the vault, and by the dead weight of any soil directly over connected foundation elements. Since liquefaction of the surrounding soil will minimize soil/concrete wall friction during a seismic event, utilizing wall friction to resist buoyancy is not recommended. If the dead weight of the vault is not sufficient to provide the required factor of safety against buoyancy, the foundations should be extended so that soil above the foundation "wings" will add to the dead weight of the structure. For granular backfill, a unit weight of 130pcf above the design groundwater level, and 67 pcf below the design groundwater level should be used to size the foundation"wings". 4.2.4.2 .Construction Considerations The main construction considerations involve the dewatering methodology utilized to complete the excavation of { the shaft. 4.2.4.2.1 Dewatering I j It will likely be costly to construct a relatively water-tight shoring system with the excavation being completed to below the depth of the ESI. In order to evaluate the possible ground settlement impacts on the.ESI of dewatering the area around the excavation, consolidation testing was completed on a soil sample obtained from the compressible silt and organic silt layer encountered in boring B-7 at a depth of 42 feet below the ground surface. At the boring location,this layer was the only soil unit considered moderately compressible below the depth of the ESI. • The results show that settlement will likely be in the range of 1 to 2 inches. The area of settlement will likely extend away from the excavation on the order of 50 feet,with the amount of settlement becoming less further away from the excavation. It should be noted that the consolidation sample was obtained from a.boring that is 20 to 30 feet away from the current ESI. It is very likely that the area was dewatered to the depth of the ESI when the ESI was constructed. If this were the case,the compressible soil beneath the ESI will have already been loaded to the extent it would be by new construction, and settlement of the pipeline would be much less. When the site is explored to further identify possible soil and groundwater contamination,an additional boring will be drilled as close to the ESI connection vault as possible. Compressible soil below the pipeline elevation will be tested, and analyses will predict settlement utilizing the new soil information. Settlement predictions will be updated at that time. In order to minimize the impacts of the vault excavation, and dewatering impacts,'it is recommended that the backfill and pipe bedding of the ESI be grouted on either side of the vault excavation so that the trench does not act as a groundwater collection trench, dewatering a large area along the pipeline. The grouting should consist of a permeation grout under relatively low pressure so that the pipe is not damaged,and so that ground heaving does not occur. The grouting effort should consider the pipe bedding and backfill up to the design groundwater level. 4.2.4.2.2 Ground Movement Ground movement because of temporary construction will be the same as described for movement of the trench • walls described in the pipeline section of this report. 20 PACRIM GEOTECHNICAL INC. I . DRAFT 4.2.4.3 Environmental Considerations Additional explorations will be completed in the area to better define the extent of soil and groundwater contamination encountered in boring B-7. A report issued at that time will define these impacts. 5.0 CLOSURE The findings and recommendations contained in this report are based on a review of existing subsurface information, the information obtained from our subsurface explorations on the project site, combined with an interpolation of soil conditions between exploration locations. Within the limitations of scope, schedule, and budget,the conclusions and recommendations presented in this report were prepared in accordance with generally accepted professional engineering principles and practices in this area at the time this report was prepared. This report was prepared for the exclusive use of the BMT design team, and should be supplied, in its entirety to potential contractors at the time of bidding. We recommend that we be retained to review those portions of the plans and specifications that pertain to foundations and earthwork to determine whether they are consistent with the recommendations in this report. We recommend that monitoring, testing, and consultation be provided by our firm during construction to confirm that the conditions encountered are consistent with those indicated by our explorations, to provide expedient recommendations should conditions be revealed during construction that differ from those anticipated, and to evaluate whether earthwork activities comply with contract plans and specifications. We appreciate the opportunity to be of service on this project,and look forward to continued involvement.

Borings B-1 & B-2 were drilled for the preliminary design of this project during the period of October 29, 1995 to October 31, 1995,by Geoboring of Puyallup, Washington,under subcontract to PacRim Geotechnical Inc. The depth of borings B-1 and B-2 was 54 feet. Borings B-3 to B-7 were 3 drilled during June 10, 1997 to June 21, 1997 by Gregory Drilling, Inc. of Redmond, Washington under subcontract to PacRim Geotechnical Inc. Boring B-5 was drilled to a depth of 34 feet and borings B-3,B-4, • B-6 and B-7 were drilled to 44 feet depth. The approximate locations of these borings are shown in Figures �a !I 3 through 15. The undisturbed soil samples were collected using Dames & Moore "U" type sampler at intervals ranging from 2-1/2 foot to 5 foot intervals in borings B-1 & B-2 and at 5 foot intervals in borings r- B-3 through B-7. The summary logs of these borings are included in this appendix as figures.A=1 through A-7 The borings are located in the field along/near the alignment of trunk line by pacing relative to existing site features. The approximate surface elevations at the borings are referenced to Metro datum. All elevations and locations are approximate and to be considered accurate to the degree implied by the methods used. All borings were drilled using truck mounted drill rigs under subcontract to PacRim Geotechnical, Inc. A 4 1/4-inch inside diameter hollow stem auger was used in all borings to maintain the stablewall inside borings while sampling. Standard Penetration Test(SPT)sampling was performed in general accordance to ASTM D-I586, with the following.exceptions. A 300 pound weigh hammer with the free fall of 3.0 inches was used drive the Dames&Moore sampler(2 inch inside diameter) 18 inches, or portion thereof. The number of blows required to drive the sampler through each 6 inches was recorded in the field. The number of blows required to drive the sampler through last 12 inches gives a quantitative measure of the relative density of the cohesionless soil or the consistency of the cohesive soil at that depth. The collected undisturbed soil samples were placed in moisture tight jars and transported to our laboratory for further observation and testing. A geotechnical engineer from our office was present throughout the fieldwork program to observe the explorations, assist in sampling and to prepare descriptive logs of the explorations. Soils were classified in general accordance with ASTM D-2488 " Standard Practice for Description and Identification of Soils —'; (Visual-Manual Procedure)". The final exploration logs represent our interpretation of the content of the logs and the results of our laboratory testing. A 15-foot monitoring well was installed adjacent to borings B-1.& B-2 using 2-inch PVC pipe. Monitoring wells ranging from 15 to 25 feet in depth were installed in borings B-3, B-5 and B-7 using 1-inch PVC pipe.. Upon completion, all other borings were backfilled by bentonite chips and soil cuttings and capped by concrete at ground surface. ry LEGEND FOR EXPLORATION LOGS SOIL CLASSIFICATION SYMBOLS FLOG SAMPLER AND WELL SYMBOLS SYMBOLS TYPICAL •,� GRAPH LETTER DESCRIPTIONS i _•ems •w s .

Laboratory tests include moisture-density determination,mechanical Analysis including hydrometer and consolidation test. SOIL CLASSIFICATION TESTS Moisture-Density Determination i Moisture content and the unit weight were determined on selected soil samples in general accordance to, ASTM D-2216. The in-situ unit weight was determined by recording the weight of the soil in the rings and the volume of the rings occupied by soil. Using calculated moisture content of the in-situ soil, the dry density was determined.This test was performed on samples 2 and 5 to 12 from boring B-3,samples 4 to 12 from boring B-4, samples 2 to 7 from boring B-5,samples l to 9 from boring B-6 and samples 2 to 10 from boring B-7. The calculated values of moisture content and dry density are presented in their corresponding summary logs in Appendix"A". Mechanical Analysis Sieve analyses were performed on selected samples for particle size larger than 751..rm. Hydrometer analysis was performed to determine the grain size distribution for particle size smaller than 75µm. Only for the soil samples which had considerable amount of fines, the combination of sieve and hydrometer analyses were used to determine the grain size distribution. The sieve analysis was performed on samples 6, 7 and 8 from boring B-3 and sample 7 from boring B-4. The combination of sieve and hydrometer'analysis was performed on samples 6 and 9 from boring B-4 and sample 4 from B-7. These tests were performed in general accordance to ASTM D-422 standard procedure. The tests results are presented in this appendix from Figures B-1 through B-3. - ONE DIMENSIONAL CONSOLIDATION TEST - This test was performed to determine the one-dimensional compressibility,time-settlement behavior and the possible maximum past pressure of the soil at that depth. This test was performed on samples 5 and 10 from boring B-7. The stress-strain curve and time-settlement curve at possible field loading conditions were obtained. This test was performed in general accordance to ASTM D-2435. The tests results are presented in this appendix from Figures B-4 through B-9. • • • • U.S. STANDARD SIEVE SIZE 31N. 1.5 IN. 3/41N.3/O IN.4 10 20 40 60 100 200 lo01 I r- I - I 1 1 r 90 I 1-____I - ' • —I • - 1— '.---- BO I----I \ -1k V, — w TO I -1--1 \ -I % . 3 m 60' I I I — er z I T 1- 40 �I I U30 �— r-- -I—1 — .

The inverted siphon's capacity is exceeded during large storm events which results in raw sewage overflows into Lake Washington. It is estimated that the system overflows about five times a year. In addition,the capacity of the downstream Bryn Mawr trunk is not adequate to convey all flows if overflows did not occur. Previous studies have examined the problem. These include a study by Metro's Engineering Services Division in 1991,a study by Brown and Caldwell entitled Local System Infiltration/Inflow Evaluation in 1993 and a report prepared by Garry Struthers Associates entitled, Technical Memorandum Evaluation of Alternatives in 1995. This was followed by a value engineering section documented in Bryn Mawr Relief Sewer Project Final Value Engineering Report in 1995. In addition a more detailed I/I analysis was completed by King County in 1996 entitled Technical Memorandum, I&I Evaluation in the Bryn Mawr District. l - This report is prepared to amend the Bryn Mawr:Evaluation of Alternatives, Technical Memorandum, July 1995. That technical memorandum evaluated a number of alternatives to reduce overflows into Lake Washington,focusing on increasing the conveyance system capacity and providing storage capacity. This report provides three primary functions. It presents the evaluation of an additional alternative to reduce overflows into Lake Washington,that of reducing I/I into the Bryn Mawr +.� system. This report also presents new project information made available after July 1995. Of major importance is a summary of King County's Infiltration and Inflow Evaluation in the Bryn Mawr Sewer District, July, 1996. Additionally this report presents the pre-design of the preferred alternative. n �r Hydraulic Design Criteria Capacity of the existing inverted siphon and trunk line is 4.5 mgd. The design criteria developed indicates that the design flows are as follows: Return Interval Peak Flow 4 Estimates j 1-year 13.3 5-year 24.4 10-year 30.7 20-year 37.0 The project's goal was to achieve a design for the 20-year return interval. } Alternative Evaluation Alternatives evaluated to reduce overflows included storage, increasing conveyance system capacity, and reduction of I&I within the Bryn Mawr. 95-008/Predesign Report/Report.doc ES-1 06/13/97 Executive Summary The use of either in-line or off-line storage was evaluated to dampen the flows prior to the inverted siphon. Land availability and topographic restrictions limited the volume of sewage that could be effectively stored at a facility. For the conveyance alternatives four routes were identified. In identifying the potential routes for a new pipeline,the two important issues were crossing the Cedar River and the City of Renton Airport runway. However,the pipe could be routed to the south where it could discharge into the East Side Interceptor after it crossed the Cedar River. Using this route the pipe could also be located to avoid the need to cross the airport runway. The four routes identified(refer to Figure 3-1)for evaluation included: Inverted Siphon • Northern Route: Construct a pipe which parallels the existing pipe. Because of the environmental impact as a result of construction within the Lake Washington(as the existing pipe was constructed),this alternative routes a new pipe on land, under the City of Renton runway and the Cedar River to the Cedar River Trail Park. A new pipe will then parallel the existing route of the Bryn Mawr trunk through the Cedar River Trail Park,turning east on North Sixth Street,and connecting to the East Side Interceptor. • Mid Airport Route: Construct a pipe southward within the Rainier Avenue rights-of-way and under the City of Renton Airport and the Cedar River at a point midway between the north and south end of the runway in alignment with North Sixth Street. The new pipe would then parallel the existing pipe on North Sixth Street and connect to the East Side Interceptor. Gravity Interceptor • Rainier Avenue Route: Construct a pipe southward within the Rainier Avenue rights-of-way and eastward along the airport perimeter road and connect into the East Side Interceptor. • Airport Route: Construct a pipe southward within the airport property between the runway and taxiway. At the south end of the airport the new pipe would be laid eastward within the perimeter road and connected to the East Side Interceptor. a`r It was determined that the preferred route was the Inverted Siphon-Northern Route. The potential to reduce I&I was assessed as an alternative. This alternative evaluated the potential to effectively reduce I/I within the Bryn Mawr Lakeridge collection system to a level such that no increase in capacity of the inverted siphon and trunk is required,or to reduce flows "G- from the district to a capacity less than the 20-year design criteria peak flow. The alternative evaluated an approach of combining I/I reduction with increasing the capacity of the Bryn Mawr inverted siphon and trunk using the Inverted Siphon-Northern Route. Various pipe sizes and associated capacities were assessed in combination with various levels of I&I reduction that could be completed within the Bryn Mawr District. The cost analysis indicated that different combinations of I/I reduction and increased conveyance capacity were relatively equal within the accuracy of the analysis(i.e.the existing 4.5 mgd conveyance capacity combined with reducing flows by 32.5 mgd through I/I reduction was relatively the same cost as increasing conveyance to 21 mgd and reducing flows by 16 mgd I/I through reduction). i' 95-008/Predesign Report/Report.doc ES-2 06/13/97 ti , Executive Summary Recommended Alternative The recommended alternative is to increase the capacity of King County Bryn Mawr system to 13.3 mgd and have the Bryn Mawr District reduce their flows by 23.7 mgd to 13.3 mgd. This is based on the following issues: • The capacity of 13.3 mgd corresponds to the a 1-year design storm. This overflow frequency compares to overflows rates anticipated in a new EPA Sanitary Sewer Overflow (SSO) Policy. • It is considered good practice to have a proactive and committed policy to control I/I within sanitary sewer collection systems. This is supported by both the Department of Ecology and the Environmental Protection Agency. • If no I/I reduction were involved, a large conveyance upgrade would need to be installed. This would involve large pipes (48")which would be under utilized unless there was a large storm event. This would result in solids deposition within the pipe due to inadequate flow velocities. This would cause maintenance and odor problems. • Overflows are occurring at an average of five per year. These are not permitted overflows and should be stopped. • King County has the ability to fund and contract a construction project to significantly reduce the overflows by January 1998. It is uncertain whether the Bryn Mawr District has the same ability to reduce overflows during that same time period. • King County does not have direct control over the flows delivered from the Bryn Mawr system.However,they do have control over the Bryn Mawr inverted siphon and trunk and can reduce overflows by increasing the pipe capacity. • The District has a record of excessive I/I. History has indicated that it is difficult to maintain low I/I levels after rehabilitation has been completed unless a well managed, ongoing program is in place. Unless I/I control is part of a sewer system's maintenance program, I/I will gradually increases people drain"wet spots"into the sewer.

BACKGROUND History of the Bryn Mawr Sewer System The Bryn Mawr Lakeridge Water and Sewer District is located in unincorporated King County. The service area is along the southwestern shore of Lake Washington adjacent to the City of Renton and the confluence of the Cedar River and Lake Washington. The District services approximately 2,000 residential customers(250 residential customer equivalents). The general vicinity of the Bryn Mawr system and its interaction with King County system's East Side Interceptor is shown in Figure 1-1. The Bryn Mawr system is defined as a separated collection system, i.e.there are separate sanitary r, sewer and storm sewer systems..However,discharges from the Bryn Mawr District into the King County system exhibit extreme variations in flow similar to a combined system,resulting in overflows into Lake Washington. These variations in flow are influenced by storm events indicating the existence of a severe infiltration and/or inflow(I/I)problem. 1 A majority of the Bryn Mawr collection system was constructed during the 1950s under conditions described by the District Manager as"swampy". During the 1950s, construction techniques were not as sophisticated in dealing with high groundwater conditions. Most of these sewers were constructed with groundwater in the trenches. The presence of groundwater gives rise to poor sealing of pipe joints and increases the likelihood of subsequent I/I problems.Due to difficult construction conditions and inadequate construction techniques,the Bryn Mawr collection system may have been prone to infiltration from the beginning with time exacerbating the problem. ' The Bryn Mawr collection system discharges into King County at the vicinity of the northwest corner of the Renton Airport. Wastewater is discharged into the inlet structure leading to the inverted siphon located partially in Lake Washington and under the Cedar River. The inverted siphon discharges into the Bryn Mawr trunk which flows along the Cedar River Trail Park. This sewer discharges into King County's East Side Interceptor. The capacity of the inverted siphon and the Bryn Mawr trunk is 4.5 mgd. When flows exceed 4.5 mgd the excess flows discharge from the inverted siphon structure into Lake Washington. Historically, due to I/I, large storm events resulted in flooded basements,manhole overflows, and siphon overflow discharges into Lake Washington. In order to relieve the basement flooding and manhole overflows,the Bryn Mawr District upgraded several lines within the system in 1993. This relieved flooding of basements,but increased overflows at the inverted siphon structure. —' This is because the improvements increased the collection system's hydraulic capacity and therefore its ability to deliver the district's sewer flows further downstream. Additionally,there is some question as to whether parts of the stormwater collection system are connected into the sanitary sewer system. The storm drainage system consists of several creeks located in ravines,open ditches along local streets,and storm sewers under the more traveled main streets. Some parts of the storm drainage system do not have as-built drawings available. The District is currently investigating their system to locate the source of excessive I/I. 95-008/Predesign Report/Report.doc 1-1 - 06/13/97 • L. ,- l i t-' -' •,,,,....4 ' "-'- 1 i▪ t .i7, , • \,1 %.� .. :t,'. +ce,•:�`\_...i4a j( -..1:'' • .V.'"-... !I'` :I: • }+.,. :3 --.`Y-J ..`p l; -^•.._...,_..4 :y L` ,t\',:7r1‘'J• A _ L -. i,•}•a' -J- • -,W= _ "zw,,... \-.''y_'.- - s. - )r': t-"i•",�'1a,,A--1:1,• L.:; 1 ., -. • y:\t'` ,.}l s rw;j _ ' 1,.•. ,: ;`, ..__ 1 - %, ▪ t;I -•i,it.'', t+, .'t u -r. ,...1p�: .t e",` • _i`• ti\-<1.-z 1_ -rs-:i ▪• , 'ti r'J ;s"r:F/:.4,11, €:11 rA 1'.44:,\ >r"rt €�"EA-.i;). :r' .,ti '' "'a'�.e. :'l. -• 'Z: 'i--a,ti a------r��i:t▪_ __ ;, \ ?1 _;.::� :Existin B ri_M . . :. .... = =:.: tm , •.,:,',�:,: T g awrwwTP;. fit```!`' `4:• '7'''cE "`� :'.. ti fir,- • "°J,�< <'� rfr;'lj, ��' = § B n Mawr, .:r,.,� � ;.°`�: € -.�:�; .. -;:..

Project Location Map Figure 1-1 a Background Past Studies The Bryn Mawr overflows have been studied extensively. In 1991 Metro's Engineering Services Division examined five alternatives to reduce overflows. This study used a design flow of 5.3 mgd. The preliminary recommendation was to conduct an I/I study to verify the design flows used. Assuming the I/I study would validate the design flow,the study recommended- converting one inverted siphon into a force main(utilizing the existing Bryn Mawr District's pump station)and replacing the existing Bryn Mawr trunk with a larger pipe. - In 1992,Brown and Caldwell(B&C)was contracted by the County to perform an I/I study and re-examine the alternatives for reducing overflows. B&C's report entitled Local System Infiltration/Inflow Evaluation-Bryn Mawr, dated December 1993, included an analysis projecting the design flows and recommended a solution to reduce overflows based on the projected design flows. B&C recommended that an 8.1 mgd flow be used to represent a 5-year return design storm and the construction of a storage facility as the best method to reduce overflows. In 1995 Garry Sturthers Associates(GSA)was contracted to validate the B&C recommendation and prepare the final design. In the first phase of the work GSA prepared a Technical Memorandum,Bryn Mawr Evaluation of Alternatives, July 1995. Furthermore, as part of this project King County's staff re-assessed the flow design criteria by including flow data recorded after the 1993 B&C work. The assessment indicated that the peak flow rates and storage requirements were larger than previously estimated by B&C(5-year: 10.5 mgd,20-year: 13.1 mgd). The flow rates and storage volumes calculated by King County were used in the development of alternatives which could potentially reduce the overflows into Lake Washington. Two approaches were evaluated: i.e. increasing the conveyance capacity of the King County system and providing storage capacity to hold the peak volumes for later release into the King County collection system. GSA recommended conveying the additional flows through the King County system to the East Side Division Reclamation Plant and presented the specific method to increase L the capacity of the conveyance piping. A value engineering(VE)team reviewed GSA's study and recommended that an Infiltration and Inflow Reduction alternative be evaluated. Implementation of design refinements were also recommended by the VE team if increasing the capacity of the conveyance system was still a component of the recommended alternative after the I/I reduction alternative evaluation.. King County initiated an I/I evaluation program during the winter of 1995-96 by installing several flow meters within the collection system in order to develop an updated characteristic of the system and to isolate areas of excessive I/I within the Bryn Mawr District. The results of this effort was presented in Infiltration and inflow Evaluation in the Bryn Mawr Sewer District Technical Memorandum, July 1996 by King County.A summary is provided in Section 2 of this document. An important conclusion of the above memorandum was that the new estimated design flow rates exceeded those previously established in 1995 in the King County Assessment. The design flows were increased due to a better understanding of the system. 95-008/Predesign Report/Report.doc 1-3 06/13/97 t i Background Current Work The I/I study indicated the Bryn Mawr District as having one of the highest rates of I/I of systems delivering flow into the King County system. King County began discussions with the Bryn Mawr District to assess the potential for reducing flows within the District's system prior to the flows entering the King County system. King County provided Bryn Mawr District with funding to initiate work on reducing the M. The District retained the services of B&C to complete a detailed assessment of the collection system. Field investigations of the system were conducted during the fall of 1996 with analysis being completed during the winter and spring of 1997. Initial results confirm that the District is experiencing excessive I/I. During the winter of 1996-97 Boeing proposed a new storm sewer outfall to be located in parallel to the Bryn Mawr trunk located in the City of Renton's Cedar River Park. The construction of the storm sewer requires that the Park be temporarily closed for public vehicle access. The City of Renton requested that King County coordinate the Bryn Mawr project with Boeing to reduce construction impact on the Cedar Rivers Trail Park. Purpose of this Report This report amends and updates the Bryn Mawr:Evaluation of Alternatives, Technical Memorandum, July 1995. The technical memorandum evaluated a number of alternatives to reduce overflows into Lake Washington by focusing on increasing the conveyance system capacity and/or providing,storage capacity. This report provides three primary functions. 7 i • the evaluation of an additional alternative by reducing I/I into the Bryn Mawr system. • updating of new project information made available after July 1995, including a summary of King County's Infiltration and inflow Evaluation in the Bryn Mawr Sewer District, July, 1996. • pre-design of the preferred alternative.

HYDRAULICS AND DESIGN CRITERIA L, Background of Hydraulic Studies The flows and hydraulics of the Bryn Mawr service area have been studied and updated over the past 10 years. Information in this pre-design report is based on information from the two recent studies, Technical Memorandum:Bryn Mawr, Evaluation of Alternatives,July 1995(TM 1995) by Garry Struthers Associates,Inc. and the draft technical memorandum by King County titled Infiltration and inflow Evaluation in the Bryn Mawr Sewer District,July 1996 (TM 1996)This section summarizes and evaluates the flow data from the above documents and presents the recommended design criteria by which the design alternatives were developed and that the new I/I reduction alternative will use. Alternative Evaluation Technical Memorandum The peak flow rates and storage volume for the various storm events presented in TM 1995 by GSA are given in Table 2-1. These values were developed from rainfall data collected in the Bryn Mawr vicinity over the past 20 years and from flow monitoring data gathered. These data were used in King County's Runoff/Transport Model Simulation in estimating these flows leaving the Bryn Mawr collection system and entering King County system via the inverted siphon inlet structure.

King County Technical Memorandum In 1996,King County initiated a detailed study of the system-wide flows within the collection system based on the recommendation by the VE team assessing TM 1995. The technical memorandum,Infiltration and inflow Evaluation in the Bryn Mawr Sewer District, dated July 1996, documented the findings of the study and analysis performed by King County from December 1995 through June 1996. The study concluded that if the Bryn Mawr District upgraded its trunk line further increasing its ability to convey wastewater to the County's II 95-008/Predesign Report/Report.doc 2-1 06/13/97 • Hydraulics and Design Criteria inverted siphon inlet structure,more flow would be brought to the siphon,resulting in more frequent discharges into Lake Washington than previously estimated in TM 1995. In this study the District was divided into ten basins. Each basin was evaluated to ascertain the source of I/I.All the individual I/I components and the sanitary flows were summed to estimate the total design flows. The basin flow estimates were used to assess the potential for each basin for the I/I reduction program. Inflow The source of inflow can be divided into two categories: the percent of impervious area directly connected to the sewers and the percent of pervious area connected to the sewers. The"percent impervious area"value represents sources such as roof leaders,catch basins,and area drains which are connected to the sanitary sewer system instead of being connected to the storm sewer system. The"percent pervious area"represents rainwater which runs overland and finds its way into the sanitary sewer system. The contribution from pervious areas to the sanitary sewer system is minimal during low intensity events but increases significantly during high intensity events. Table 2-2 summarizes the inflow parameters presented in TM1996. The table also compares Bryn Mawr parameters to a typical"tight"system with low I/I(Woodinville). Table 2-2.

Trench infiltration comes from water that collects in the pipe trenches and enters the pipe through cracks or separated joints. Groundwater infiltration occurs,when the water table rises above the elevation of the pipe. Table 2-3 compares the calculated peak infiltration rates and the dry weather flows. It also shows the high infiltration in the basins. 95-008/Predesign Report/Report.doc 2-2 06/13/97 Hydraulics and Design Criteria Table 2-3.

Compared with other separated systems within the Metro service area,the Bryn Mawr system is the leakiest system. Infiltration and inflow in the Bryn Mawr system contribute substantially to the system peak flows. All the basins in the system will require rehabilitation in an I/I reduction i program, if implemented. Peak Flows The results presented in TM1996 indicate Bryn Mawr system peak flows are significantly higher than estimated in previous studies. Table 2-5 shows the design flows from TM 1996. These are the potential flows that the District could deliver to the inverted siphon structure. They are not 95-008/Predesign Report/Report.doc 2-3 r_, 06/13/97 • Hydraulics and Design Criteria the actual flows reaching the siphon inlet structure due to the existing flow restrictions in the collection system. Table 2-5. Bryn Mawr District 1996 Design Flows(MGD) Return Interval Peak Flow Estimates 1-year 13.3 5-year 24.4 10-year 30.7 20-year 37.0 Storm Return Frequency Design Criteria King County's policy is to allow one overflow every 20-years from a separated system, such as the Bryn Mawr system. Because phasing of the recommended alternative may be necessary to accommodate funding,a review of return frequency design criteria and overflow policy is helpful in finalizing the alternative for recommendation. The Bryn Mawr system,being a separated system strongly influenced by I/I, exhibits system overflow characteristics similar to that of a combined system. Since the Department of Ecology allows one overflow per year from a combined system, it may be argued the Bryn Mawr system should qualify for similar overflow annually due to the fact that it behaves like a combined system.. The Environmental Protection Agency has established a committee to assist in developing a National Sanitary Sewer Overflow(SSO)Policy. Preliminary indications from the committee are that this new policy would be a policy whereby municipal entities can"negotiate"a reasonable and representative frequency for SSO occurrences. Under this policy, each municipality would set a goal and would work to stay below the agreed frequency. It is anticipated the agreed frequency would be in the 1-year to 5-year range for most municipalities. The EPA is expected to publish a document by the end of 1997 outlining this policy and its parameters.' ti 'Conversations with Dan Schecter,Water Environment Federation,July 29, 1996 and March 17, 1997. 95-008/Predesign Report/Report.doc 2-4 06/13/97 i . 3. SUMMARY OF BRYN MAWR EVALUATION OF 1 ALTERNATIVES - TECHNICAL MEMORANDUM The Bryn Mawr Evaluation of Alternatives- Technical Memorandum(TM 1995)prepared by GSA presented a detailed evaluation of several storage and increased conveyance alternatives based on the 13.1 mgd,20-year peak flow as established by the design criteria at that time. The conveyance capacity of the existing Bryn Mawr system is 4.5 mgd. The GSA study considered increasing system storage or system conveyance as the two options to reduce overflows in evaluating the alternatives. Various configurations of these options were assessed resulting in one storage alternative(with three deviations)and two conveyance alternatives(with two deviations each)being evaluated. Following is a summary of the evaluation and recommendations from TM 1995. Additionally a downstream impact analysis which was not included in TM 1995 is also presented at the end of this section. The storage alternative evaluation included assessment of implementing either in-line or off-line storage,with the off-line storage being provided by a new cast-in-place concrete structure. None of the storage configurations could provide the required storage volume of 4.6 mg to reduce the 20-year flow of 13.1 mgd to the system conveyance capacity of 4.5 mgd. Storage facilities meeting the 1 and 5 year storage requirements could be provided and thus were identified and assessed. The 5-year facility was a cast-in-place concrete facility located near the inverted siphon inlet. Two variations each for the two conveyance alternatives resulted in four routes being evaluated. The two issues considered for the potential routes were the crossing of the Cedar River and the City of Renton Airport runway. The pipeline could be laid such that it would require crossing of the City of Renton Airport and the Cedar River; or laid to the south,to connect to the East Side Interceptor after it crossed the Cedar River,thus eliminating the Bryn Mawr Trunk Cedar River crossing and the pipe could be located to avoid crossing the airport runway. The four routes identified for evaluation are shown on Figure 3-1,and are as follows: Inverted Siphon • Northern Route: Construct a pipe paralleling the existing pipe. This alternative routes a new pipe on land to avoid environmental impacts of water-based construction,under the City of Renton runway and the Cedar River to the Cedar River Trail Park. A new pipe will then parallel the existing route of the Bryn Mawr trunk through the Cedar River Trail Park, turning east on North Sixth Street,and connecting to the East Side Interceptor. • Mid Airport Route: Construct a pipe southward within the Rainier Avenue right-of-way and under the City of Renton Airport and the Cedar River at a point midway between the north and south end of the runway in alignment with North Sixth Street. The new pipe would then parallel the existing pipe on North Sixth Street and connect to the East Side Interceptor. Gravity Interceptor • Rainier Avenue Route: Construct a pipe southward within the Rainier Avenue right-of-way and eastward along the airport perimeter road and connect into the East Side Interceptor. • Airport Route: Construct a pipe southward within the airport property between the runway and taxiway. At the south end of the airport the new pipe would be laid eastward within the perimeter road and connected to the East Side Interceptor. 95-008/Predesign Report/Report.doc ,3-1 -, 06/13/97 . • } Summary of Bryn Mawz Evaluation of Alternatives Technical Memorandum -- - - NIP-- __„ - Q+ 1�.�� 4f�.;F �`\'..�'I!r T° r�, �•.t- EP1FP :k ter: i.-apt- �y'-..r-r. s, c n��l :. � ��- _, � � !r �•�•� �.r--'r"'�: : _ r• y � - gym _ �}� - II �. - -�•s. % I i" ; �-t•'-." .!----"'>: - ,�' . --�� iA:,, Jreve.a r• fn • i! 1'( �`:._ i'?..�TillatialP ��-•�'� � R ` - r V, 3 Qs,S' T jL�y �-!� �:. _ 7•f Y Eft . 1 '. rsctrw:_v a� • ► f�.a �tr v. s ' i I p - • '"" rt , • YSY;.,:1„•^ L i.�'] 'ran ' ��rri.4• }t ' ` '� J'• ;�vlk - _ � � , ,�• .11��}''. r• jI 3 = co r i. 7s or t , �,EY 'v - nVt ` G --11 F ' Mil ; ' . - " A 4.

The inverted siphon,buried in Lake Washington, consists of two barrels(1,545 feet in length), beginning as 10-inch and 16-inch in diameter at a location 67 feet from the inverted siphon inlet structure,and then decreasing to 8-inch and 14-inch in diameter respectively The inverted siphon connects to the Bryn Mawr trunk(27"diameter)which runs south and then east prior to its connection to the East Side Interceptor. The existing Bryn Mawr inverted siphon and trunk have an estimated capacity of 4.5 mgd. The existing condition of the inverted siphon is difficult to determine without actually removing a coupon of the pipe wall. It was determined that removing a coupon was not in the best interest of the project because of the high expense in dealing with a pipe buried under water and because this process can potentially weaken the pipe's integrity. The nature,environment, and location of the existing pipe were investigated to assess corrosion potential. Indications are the pipe is not in a corrosive environment and may have many years of useful life ahead Nevertheless without a coupon from the pipe barrel,the current condition of the invert siphon cannot be made. The Bryn Mawr Trunk line, in to which the inverted siphon is connected, is reported to be in good condition. There have been no maintenance problems with the line. Design Criteria The alternatives were evaluated utilizing the design flows established in 1995 as summarized in Section 2 of this report and repeated here in Table 3-1. Table 3-1. Bryn Mawr 1995 Design Values Design Event Peak Flow Storage Volume Size(years) Rate(mgd) (mg) 1 7.7 0.8 5 - 10.5 _ 2.9 10 11.8 3.8 • 20 13.1 4.6 Storage and Conveyance Alternatives Evaluation L ' Storage In-line storage was assessed by constructing a new large diameter pipeline in Rainier Avenue North. Due to the existing Bryn Mawr system layout, it would be difficult to direct enough flows through the proposed pipe to generate flushing velocities;therefore,this configuration was not pursued further. tl Three configurations for an off-line storage facility were evaluated. One is to build a large- r- diameter pipe within Rainier Avenue North. The second is to utilize the abandoned Bryn Mawr wastewater treatment plant structures as much as possible. The third configuration is to demolish the existing facility and build a new storage facility. Both the first and second configurations 95-008/Predesign Report/Report.doc 3-3 r 06/13/97 Summary of Bryn Mawr Evaluation of Alternatives- Technical Memorandum have physical limitations allowing for a maximum size of 0.8 mg. This size storage would only reduce a 1-year peak flow of 7.7 mgd to 4.5 mgd. The third configuration is the construction of a new off-line cast-in-place concrete structure as shown on figure 3-2. It was determined that a new facility could be built in the vicinity of the abandoned Bryn Mawr WWTP facility. Although this land is now privately held,Metro could acquire the land for use as a storage facility. However,because of site limitation this facility could only accommodate up to a 5-year storm. Impacts and Issues • The site being remote will require security, operation and maintenance. • The property is surrounded by residential use. • The structure floor will be below the water table. Increased Conveyance Inverted Siphon Alternative Two potential routes were identified to convey increased flows to the East Side Interceptor. Both of these routes included a new inverted siphon and gravity trunk line. The inverted siphon was developed to include an air jumper and duel barrels,both features preferred by King County staff. Because of the uncertainty of the condition of the existing inverted siphon the alternatives were presented in the TM 1995 with the existing inverted siphon being abandoned. However, in response to value engineering comments,the inverted siphon was modified to eliminate the air jumper and one new barrel of the inverted siphon with the existing inverted siphon to remain in service. The new barrel was sized at 24-inch diameter. The alternatives presented in this report have incorporated these modifications. Northern Route The Northern route approximately parallels the existing Bryn Mawr inverted siphon and trunk. This route is 5,880 feet long,with a 1,480 feet long inverted siphon under the Renton Airport Runway and Cedar River. The inverted siphon is located at the far north end of the Renton __ airport,and would discharge into a 36"diameter gravity pipe within the City of the Renton's Cedar River Trail Park. The new pipe would closely follow the alignment of the existing Bryn — Mawr trunk proceeding south in Riverside Drive through the park and turn east at the North Sixth Street Intersection and again parallel the existing sewer trunk until connecting with the East Side Interceptor at Burnett Street. Impacts and Issues • • Microtunneling or directional drilling would be required to construct the pipe under the -, airport runway and Cedar River. The preliminary geotechnical investigation indicates that the soils are conducive for this type of construction;however,this type of work has a higher degree of construction uncertainty than conventional open trench construction. • Two existing mobile homes along the northern portion of this route are in conflict with the r- , proposed pipeline. It may be necessary to either relocate the occupants or bore and jack under the homes. 95-008/Predesign Report/Report.doc 3-4 06/13/97 ' Summary of Bryn Mawr Evaluation of Alternatives- Technical Memorandum .1 7- 1 r _ter ' -.� jr -�` _ ' f * • � � , ' '; - - k4 l ~4 ;. ._ �.- `"" gyp r. si v r t ''I Storage Facility " '-' -ter - t e : . , _ Footprint , Fa a x �+►1` f 5 Year Event yt .. 4 C s •1 7 , : >�', �_ K .ems _ .� A $ " x '_ s _,'i�S+ ''r `Tom - "'7., `r` ',t ' ' - ~-�,� • 1� ; ' a«.

Mid Airport Route The mid airport route begins on Rainier Avenue and generally follows Rainier Avenue southward until the middle of the airport and then enters an inverted siphon. This route is a total of 6,520 feet long with a 1,505 feet long inverted siphon under the Renton Airport Runway and Cedar River. The inverted siphon would discharge into a 36"diameter gravity pipe at the intersection of Riverside Drive and North Sixth Street. The new pipe would closely follow the alignment of the existing Bryn Mawr trunk along North Sixth Street and parallel the existing sewer trunk until connecting with the East Side Interceptor at Burnett Street. Impacts and Issues • Higher potential for uniform soil conditions for the micro tunneling portion of the project than the Northern Route. • Traffic and businesses would be impacted on Rainier Avenue. • Isolated area at the inverted siphon inlet has a lower potential for odor complaints than the northern route. • Of the 5,320 feet of open trench construction required,approximately 3,000 feet would be over 15 feet deep. • The Bryn Mawr District's Lakeshore pump station and force main would require modifications. The force main would need to be extended 400 feet and the pumps also modified to accommodate the increased dynamic head and 1.5 feet of static head. • A portion of the Bryn Mawr District's collection system flows into the Lakeshore pump station. This flow could be tied directly into this proposed pipe,thus reducing usage of the pump station. • The pipe could serve the future flows from the Renton West Hill. • Groundwater along the pipe alignment along North Sixth Street will be 5 to 8 feet below the ground surface. • Construction of the Bryn Mawr Trunk at the entrance to the Cedar River Tail Park would require closure of vehicular access to the park for up to 2 weeks. • There are no significant environmental issues or impacts identified at this time. t_ 95-008/Predesign Report/Report.doc 3-6 06/13/97 Summary of Bryn Mawr Evaluation of Alternatives- Technical Memorandum Gravity Trunk Line Alternative The two gravity interceptor routes,Rainier Avenue Gravity Route and Airport Gravity Route avoid the need for an inverted siphon by connecting to the East Side Interceptor to the south and hydraulically down gradient of the Cedar River and south of the Renton Airport. Therefore, neither the airport runway nor the Cedar River would need to be crossed by the pipeline. Rainier Avenue Gravity Route This gravity route begins on Rainier Avenue and generally follows Rainier Avenue southward until Airport Way,then turns eastward along the southern airport perimeter road, crosses Logan Avenue and connects with the East Side Interceptor. The interceptor would be 8,340 feet in length using a 36"diameter pipe. The existing Bryn Mawr inverted siphon would be abandoned. Impacts and Issues • Traffic and businesses would be impacted on Rainier Avenue • Of the 8,340 feet of open trench construction required,approximately 7,900 feet would be over 15 feet deep. • The depth to invert for approximately 3,600 feet ranges from 20 to 32 feet deep. Bedrock may be encountered on this portion. • The Bryn Mawr District's Lakeshore pump station and force main would require modifications. The force main would need to be extended 400 feet and the pumps also modified to accommodate the increased dynamic head and 1.5 feet of static head. • A portion of the Bryn Mawr District's collection system flows into the Lakeshore pump station. This flow could be tied directly into this proposed pipe,thus reducing usage of the pump station. • The pipe could serve the future flows from the West Hill Renton. - • Boring and jacking under Logan Avenue would be required to connect to the ESI. • There are no significant environmental issues or impacts identified at this time. Airport Gravity Route This route begins at the existing inverted siphon inlet, follows the Lake Washington shoreline through the Mindemann Restaurant parking lot(similar to the North Inverted Siphon Route),and then travels east to the eastern side of the west taxiway within the airport. The route then turns south and parallels the runway until it reaches the south end of the airport at the perimeter road. The route then turns eastward in the perimeter road,crossing Logan Avenue and connecting to the East Side Interceptor(similar to the Rainier Gravity Route). The interceptor would be 7,980 feet in length and use a 42"diameter pipe. The existing Bryn Mawr inverted siphon would be abandoned. Impacts and Issues • Of the 7,980 feet of open trench construction required, approximately 2,100 feet would be over 15 feet deep. • The pipe could serve the future flows from the West Hill Renton. --- • Boring and jacking under Logan Avenue would be required to connect to the ESI. 95-008/Predesign Report/Report.doc 3-7 06/13/97 Summary of Bryn Mawr Evaluation of Alternatives- Technical Memorandum • There are no significant environmental issues or impacts identified at this time. • There is limited access to the portion of pipe within the airport property. • Two mobile homes exist along the northern portion of this route and in conflict with the proposed pipeline. It may be necessary to either relocate the occupants or bore and jack under the homes. • The alternative requires the highest flow of all alternatives to achieve a flushing velocity. In-line Storage Option In-line storage option was presented in TM 1995 for all alternatives and consisted of construction of an over sized pipe in a section prior to connection to the East Side Interceptor. The oversized section of pipe would be used for storage to reduce impact on the East Division Reclamation Plant. This option of the inverted siphon-northern route modified the alternative by constructing the down gradient portion of gravity pipe as an 84"diameter pipe. This option does not impact the alternative selection because it is located downstream of the inverted siphon and does not impact the flows through the inverted siphon. It does however reduce the downstream impacts of the flows. Impact on the flows was determined by hydraulic modeling. The analysis indicated that the maximum flow reaching the East Side Interceptor would be 8.1 mgd. However,the analysis also indicated that the same flow would have a 8.3 mgd impact on the Eastside Division Reclamation Plant, an increase of 0.2 mgd over the East Side Interceptor flow,clearly an impossibility. A flow of 8.4 mgd was used to project the impact on both the East Side Interceptor and Eastside Division Reclamation Plant to compensate for the inaccuracies in the hydraulic model. Downstream Impact Costs Downstream impact costs need to be considered when evaluating alternatives to accommodate the Bryn Mawr flows. Increasing capacity in the siphon and the gravity sewer line will increase flows to the East Side Interceptor,the Eastside Reclamation Plant,and the Effluent Transfer System. Increasing downstream flows by upgrading hydraulic capacity must be weighed against the option of reducing infiltration and inflow within the Bryn Mawr collection system. The downstream cost analysis for this report considers the marginal cost of accepting additional peak flow from the upgraded Bryn Mawr conveyance system.-This is done by assessing the unit- cost of the downstream facility improvements needed to accommodate the additional peak flows. The anticipated downstream facilities are outlined in Wastewater 2020 Plus: Conveyance and Treatment Alternatives Screening and Refinement, Task 6.1.3 Final Report, January 1996, HDR Engineering, Inc.(HDR 2020 Report). The downstream impact costs are taken from the planned upgrades downstream of the Bryn Mawr system,namely the East Side Interceptor and the Effluent Transfer System. It should be noted as to which alternatives King County will implement from the HDR 2020 report are not known at this time. However, it appears that the following improvements are the most likely to be implemented for this area. These involve the following projects represented in 1995 costs as shown in the HDR 2020 report: 95-008/Predesign Report/Report.doc 3-8 06/13/97 Summary of Bryn Mawr Evaluation of Alternatives- Technical Memorandum 1. Effluent Transfer System Conveyance: Project Capacity Total Project Cost per Increase Cost(million) Gallon Pump Station 90 mgd $18.1 0.201 3rd Outfall 195 mgd $16.5 0.085 Booster P. Station 195 mgd $79.2 0.406 Total 0.692 2. Effluent Transfer System Storage: Provide 90 mgd storage; project costs estimated at$35.2 million and$0.391 per gallon 3. Upgrades to the East Side Interceptor, Section 1: Provides a capacity increase of 150 mgd. Consists of two projects with cost estimates of$9.3 and 7.9 million,and a cost of$0.115 per gallon. Table 3-2 shows the planned upgrades to these facilities and the average cost per gallon for each facility. An average cost of the Effluent Transfer System (ETS)conveyance and ETS storage was used because the Bryn Mawr flows would impact either system but not both. The average ETS cost is added to the cost per gallon for the East Side Interceptor upgrades. This provides a downstream impact cost for flows from the Bryn Mawr system. This cost were applied to all flows above the existing system's design capacity of 4.5 mgd. Table 3-2. Downstream Impact Costs Associated with the Bryn Mawr System Projects Identified Cost per Cost per gallon gallon (1995 (1997 dollars) dollars) ETS Conveyance $0.692 ETS Storage to Reduce Peak Flows by 90 mgd $0.391 Average Effluent Transfer System Cost $0.5415 East Side Interceptor Section 1 $0.115 Downstream Costs Associated with Bryn Mawr Average ETS Cost $0.5415 East Side Interceptor Section 1 $0.115 Total Costs , $0.656 $0.710 Total downstream impacts are calculated by multiplying the cost per gallon by the rate of flows impacting the East Side Interceptor and ETS. By hydraulic analysis the design flow of 13.1 mgd is reduced to a flow of 12.8 mgd when the Bryn Mawr trunk discharges into the East Side Interceptor and 11.1 mgd when the flows reach the East Division Reclamation Plant. To account for this hydraulic dampening of the flows prior to their reaching the ESI and ETS,the total flows are reduced by an average of 10%and then multiplied by the total cost per gallon of $0.710/gallon.

On assessing the cost and other issues for each alternative,the Northern Inverted Siphon alternative was determined to be the least cost alternative, either with or without in-line storage. This alternative also does not have any significant engineering, operation and maintenance, or environmental and/or social impacts. Thus this alternative was recommended as the preferred alternative in TM 1995 Therefore the recommendation from the TM 1995 was that in considering the alternatives of storage or conveyance the best alternative for implementation was to increase the conveyance system capacity by constructing a new pipeline along the northern inverted siphon route. Refinement of Preferred Alternative A value engineering session was held to review the recommendations presented in TM 1995, which was prepared at the conclusion of the alternative study phase of the project. No suggestions were made to revise the proposed route alignment,that of the inverted siphon- northern route;with suggestions made on ways of reducing the cost. Value engineering team suggestions were reviewed for applicability and the following accepted. f • Do not abandon the existing inverted siphon. Install new inverted siphon as a single barrel. Make capacity of the single barrel equal to the peak capacity to allow for abandonment of the existing pipe in the future. • Eliminate the air jumper for the inverted siphon.King County staff confirmed that the existing inlet to the inverted siphon currently does not create an odor problem,justifying the elimination of the air. • Eliminate the casing pipe in the tunneled section. With the elimination of the second barrel of the inverted siphon and the air jumper,the casing and carrier pipe can be the same pipe. • Investigate the reduction of the infiltration and inflow into the Bryn Mawr system to reduce • the capacity design criteria of the proposed interceptor. The evaluation of this alternative is presented in detail in Section 4 of this report. 95-008/Predesign Report/Report.doc 3-11 06/13/97 4. INFILTRATION AND INFLOW REDUCTION ALTERNATIVE This alternative evaluates reducing I/I to a level such that no increase in the conveyance capacity of the Bryn Mawr inverted siphon and trunk is required, or a conveyance capacity less than the TM 1996 20-year design criteria peak flow is required. This section develops the most cost effective combination of I/I reduction and increased capacity to the Bryn Mawr trunk. Cost to Reduce Inflow & Infiltration in the Bryn Mawr Collection System Since I/I is a substantial component of the design flows, its reduction will lower or eliminate the need for the upgrade of the Bryn Mawr inverted siphon and trunk. This I/1 reduction analysis is based on the hydraulic evaluation summarized in Section 2 of this report. Currently the Bryn Mawr District is performing a detailed investigation to obtain a better understanding, and ti identifying the sources of I/I of the Bryn Mawr collection system. The work involves smoke testing and a video study of the collection system. Results from the District's study should be reviewed to validate and confirm the recommendations made in this study. The hydraulic data summarized in Section 2, indicate the I/I problem to be widespread throughout the basins in the entire system. No source of significant direct storm connections can be identified. All basins have high infiltration and inflow rates. Since the I/I exist for the entire system the best I/I reduction alternative is the replacement of the entire sanitary sewer system and the construction of a storm sewer system where needed. This is based on the experience that rehabilitation of one system component(e.g. side sewers)does not significantly reduce I/1. The I/I is reduced locally;however,the I/1 increases elsewhere in the system. For this analysis representative units costs were developed to evaluate sewer replacement costs for the Bryn Mawr collection system. Items considered in developing the unit costs included the following: • Sanitary Sewer In-Place: Includes sewer pipe, excavation,bedding, imported backfill, haul and disposal of surplus material, and full width roadway restoration. • Allowance for Storm Sewer: It was assumed that the existing sanitary sewer would be converted in use to a storm sewer system. Additionally construction of some new storm sewer would be required. It was estimated that the length of new storm sewer required would represent 25% of the total length of sanitary sewer pipe. • Contingency: This is an allowance for uncertainties in the planning level estimate, and estimated to be 20% of the base construction costs. • Sales Tax: State Tax at 8.2%. • Allied Costs: Costs associated with engineering, construction management, and administration of the sewer replacement project. This is estimated at 35% of the total estimated construction cost. Table 4-1, summarizes the unit costs used for evaluating a sewer replacement option. Appendix B presents a detail breakdown of the costs. 95-008/Predesign Report/Report.doc 4-1 06/13/97 Infiltration and Inflow Reduction Alternative 1 Table 4-1.Project Costs to Reduce Infiltration and Inflow within the Bryn Mawr Collection System Cost per linear foot Item 8-inch 10-inch 12-inch 15-inch 18-inch Sanitary Sewer 98 104 $108 121 $130 Allowance for Storm Sewer 23 23 23 23 23 Contingency 24 25 26 29 30 Sales Tax 12 12 13 14 15 Allied Costs 55 57 60 65 69 Total Cost $212 $221 $230 $252 $267 Side Sewer Connection $3,500/ea r, The basins within the Bryn Mawr service area were evaluated and prioritized for replacement. Basins with largest I/I were assigned top priority and those with less I/I a lower priority.

It also demonstrates that it is difficult to eliminate I/I from the system completely. Cost to Increase Capacity of the Bryn Mawr Trunk The costs associated with increasing the conveyance capacity of the Bryn Mawr trunk involve " construction costs and downstream impact costs. The conveyance upgrades for the recommended alternative,the northern inverted siphon route, involve two components: the inverted siphon and the gravity trunk. This alternative was described in Section 3 of this report. 1' King County has several options for increasing the conveyance capacity of the Bryn Mawr delivery system depending on the size of pipe used.

Summary of Costs Associated With Conveyance Improvements and Downstream Impacts Costs ( The cost to increase the conveyance system from the inverted siphon structure to the East Side Interceptor and downstream impact costs are interrelated.

The table indicates that a total I/I reduction program with no 1; i increased conveyance is the lowest cost alternative. However,since costs of all alternatives are within 20%of the lowest cost,and the accuracy of the costs developed in this study is+20%,the evaluation has indicated that all combinations of rehabilitation and I/I reduction have similar costs. _ Environmental/Social Issues '1 The environmental and social issues associated with installing conveyance improvements from the siphon outlet structure to the East Side Interceptor have been detailed in TM 1995.The issues involve traffic impacts to some routes near the park, disruption of access to Boeing airport I facilities along Sixth Street,temporary disruption of the Mindemann's Restaurant parking lot, closure of the Cedar River Trail Park during construction,and noise increases due to construction activities. Environmental and social impacts associated with the work to reduce I/I within the Bryn Mawr District are difficult to specify at this time. The sewer replacement projects would occur over an is- extended period of time as scheduled by the Bryn Mawr District. It is not known when sewers would be replaced within each of the designated basins and how large each replacement project might be. Replacement projects have not been defined and designed making it difficult 111 evaluating the environmental and social issues for the alternative. However, it is anticipated that no significant impacts would result from the sewer replacement work. 1" Additional Considerations In addition to the technical analysis and review of environmental and social impact, additional engineering considerations have been identified. These include the following: r� 95-008/Predesign Report/Report.doc 4-6 �,,_ 06/13/97 Infiltration and Inflow Reduction Alternative Establishing a proactive and committed policy to control I/I within sanitary sewer collection systems. This is supported by both the Department of Ecology and the Environmental Protection Agency. Reduced I/I will minimize peaks in the system influenced by storm events. This will allow the system to function normally and will reduce the chances of a Sanitary Sewer Outflow (SSO). Additionally,if no I/I reduction were involved,a large conveyance upgrade would be needed. This would involve large pipes(48") which would be under utilized except during infrequent large storm events. This would result in solids deposition within the pipe due to inadequate flow velocities. This would cause maintenance and odor problems. The urgency to reduce SSO's into Lake Washington is another important issue related to this project's future. SSO's have been occurring more frequently than King County or the EPA accept for separated sewer systems. However, investigation and correction of I/I problems can sometimes be a long process. It could be possible to increase the capacity of the Bryn Mawr conveyance system quickly,whereas I/I correction might take longer due to the District's limited 4 ability to fund construction work. Recommended Infiltration and Inflow Reduction Alternative The technical analysis indicated that the cost-effective approach to this alternative could be any 1 combination of increased conveyance and reduction of I/I. Additionally there are no significant ' environmental and social impacts associated with either increasing the Bryn Mawr inverted siphon and trunk or I/I rehabilitation work within the Bryn Mawr District. Sound engineering 1 judgment is used to define the best I/I reduction alternative. It is recommended that a combination of increased conveyance and I/I reduction within the collection system represent the I/I reduction alternative.It is specifically recommended that the Bryn Mawr inverted siphon and trunk are increased in capacity to convey a 1-year storm(13.3 mgd). I/I reductions within the Bryn Mawr District should reduce the peak flow from the current 20-year peak of 37.0 mgd to 13.3 mgd. 1 This recommendation is based on the following facts: • There are currently about five overflows a year from the Bryn Mawr inverted siphon. Some of these last more than a day in length. • The Bryn Mawr system has the highest rate of I/I of any system which delivers flows into the King County system. Because the King County system is reaching capacity,King County 1 'll policy should not continue to let extreme high I/I flows continue. • The water quality of the overflows is likely to be similar to a CSO. The Washington State Department of Ecology allows one overflow a year from a CSO,therefore an interim design criteria of 13.3 mgd(1-year storm)is reasonable. • One overflow per year is within the range EPA is currently considering for new SSO regulations. • The inverted siphon has been in service over 30 years; a new inverted siphon will increase system reliability. I Fulfilling the requirements of this recommendation would involve the following: ! % 95-008/Predesign Report/Report.doc 4-7 06/13/97 r Infiltration and Inflow Reduction Alternative _" • Installation of a 24-inch diameter siphon and a 36-inch diameter gravity line from the siphon outlet structure to the East Side Interceptor. This upgraded conveyance system would accommodate a flow of 13.3 mgd and will cost approximately$6.5 million. This would provide sufficient hydraulic capacity to accommodate a 1-year storm. • Implementation of an I/I reduction program within the Bryn Mawr Sewer District. This program would need to be implemented to a level which would bring the peak system flows during a 20-year storm event down to approximately 13.3 mgd. This program would cost approximately$14.8 million. This would involve investigating and correcting infiltration and 111 inflow connections to the system in Basins 6, 10,3 and part of 7. It would be achieved by replacing the sewer lines in those basins using modern construction techniques. Inflow connections would be discovered and corrected during construction. Once the I/I reduction measures are completed to reduce total flows leaving the Bryn Mawr District,and the conveyance system between the siphon outlet structure and the East Side Interceptor upgraded,the system will be able to accommodate a 20-year storm in accordance with King County policy for a separated system. r • i 11 I. ,~ 11�� II r 4`I 741 95-008/Predesign Report/Report.doc 4-8 �; 06/13/97 ` 1 5. ALTERNATIVES EVALUATION AND RECOMMENDED U ALTERNATIVE PRE-DESIGN Section 4 developed the preferred increased conveyance alternative to include I/I reduction to make it more cost effective. Recommended Alternative a Based on the technical evaluation both the comprehensive I/I reduction program and the Bryn Mawr system conveyance capacity increase with some I/I reduction alternatives are equal in cost and environmental and social impacts considering the accuracy of the evaluation. However, certain issues favor the construction of the 13.3 mgd inverted siphon with I/I reduction in the Bryn Mawr system. These include: • Overflows are occurring at an average of five per year. These are not permitted overflows and should be stopped. • King County has the ability to fund and contract the construction project to significantly reduce the overflows by January 1998. It is uncertain whether the Bryn Mawr District could have the same ability to reduce overflows during that same time period. • King County does not have direct control over the flows delivered from the Bryn Mawr !, l system, whereas they do have control over the Bryn Mawr inverted siphon and trunk and can reduce overflows by increasing the pipe capacity. • The District has a record of excessive I/I. History has indicated that it is difficult to maintain low I/1 levels after rehabilitation has been completed. I/I gradually increases during the following years as people drain "wet spots"into the sewer. Therefore, it is recommended that King County consider increasing the capacity of the Bryn Mawr conveyance system to 13.3 mgd. Recommended Alternative Pre-Design Preliminary plan and profile of the recommended is the inverted siphon -northern route , alternative are shown Appendix D. The following features are included in the pre-design. • Concrete or ductile iron pipe will be used for the gravity portion of the project. No special pipe linings will be required. King County inspection indicates Bryn Mawr trunk concrete pipes'does,not show any sign of deterioration. • The inverted siphon will be single barrel, therefore the casing and carrier pipe will be the same pipe. • The inverted siphon will be designed to drain. An access vault will be built at the downstream end of the siphon.

B. It is the bidder's responsibility to ensure that all firms projected for use to meet the M/WBE goals are certified by the State OMWBE at the time bids are submitted. Firms which have not been certified by the State OMWBE by the bid submittal date and time shall not be considered by King County in determining whether the bidder has met the goals and complied with these requirements. To determine whether a firm has in fact been certified by the State OMWBE a bidder shall contact the State OMWBE at (360) 753-9693, or utilize the OMWBE Directory of Certified Minority, Women and Disadvantaged Business Enterprises in effect on the date bids are due. 1. In the event of a discrepancy between the classification(as an MBE,WBE,CBE or MWBE) of a firm in the OMWBE Directory, and the classification verbally given by the OMWBE, the classification in the OMWBE Directory will control. 2. If a business listed by the bidder in Attachment A to its Statement Regarding Minority and Women Business Enterprise Commitment form is not certified and does not appear in the OMWBE Directory, the utilization of said business will not be counted toward the fulfillment of any utilization goal, and the bidder shall not substitute another firm. 3.

In the event that the ineligible certified firm is the bidder, the bid shall not be considered for award of this Contract by King County unless the utilization of other remaining certified firms listed by the bidder meet or exceed the established goal for this Contract. • C73130C 00120-4 M/WBE AND EEO PROGRAM REQUIREMENTS 1.07 MINORITY AND WOMEN BUSINESS ENTERPRISE SOLICITATION AND UTILIZATION PROCEDURES A. Utilization of minority and women's business enterprises may be accomplished through contracting, subcontracting, joint ventures, procurement of supplies, materials or equipment, or by such other methods as may be approved by King County's M/WBE and Contract Compliance Division. B. CONTRACTING (BIDDER)METHOD If the bidder is a certified firm,it may count its own participation toward meeting the utilization goals, in accordance with paragraph 00120-1.08. C. SUBCONTRACTING METHOD The bidder may utilize certified firms on the basis of competitive bids and/or negotiated subcontracts. The bidder shall submit at the bid evaluation conference, or upon request, copies of letters of intent signed by the bidder and counter-signed by the certified firm. Such letters of intent shall set forth the scope and dollar value of the work to be performed by the certified firms, consistent with the bidder's projected use of the certified firm in th bid document. D. JOINT VENTURE METHOD A joint venture (either as a bidder or proposed subcontractor) between a non-certified firm and one or more certified firms may be used to meet the utilization goals, if the certified partner(s) is/are certified by the State OMWBE and the certified partner(s) is/are responsible for a clearly defined portion of the work which is detailed separately from the work to be performed by the non-certified joint venture partner. Only the work to be performed by the certified partner(s) shall be counted toward the applicable utilization goals. Such agreement shall identify the extent to which each joint venture partner shares in the ownership, control, management, risks and profits of the joint venture. The certified partner's portion of the work shall be assigned a commercially reasonable dollar value if that portion is intended to meet a dollar level based utilization goal for this Contract. Thee burden of persuasion shall be on the joint venture partners to demonstrate to the satisfaction of King County that the certified partners will perform a commercially useful function, as defined herein, under the joint venture agreement. Any such joint venture will be subjected to close scrutiny by King County. Even though a proposed joint venture agreement may be consistent with legal principles of contracting and with normal industry practices, that, in and of itself, does not mean that King County will determine that the joint venture will satisfy the utilization goals set forth herein. Bidders or subcontractors intending to use a joint venture to meet utilization goals should submit the joint venture agreement to King County two weeks before bids are due so that King County can determine whether the joint venture can be counted toward the utilization goals. The bidder assumes the risk that the joint venture will not be counted by failing to submit said joint venture agreement to King County for prior determination. 1.08 DETERMINING WHICH GOAL TO COUNT A CERTIFIED FIRM'S UTILIZATION TOWARDS A. Participation by certified firms, regardless of tier, which will perform commercially useful functions shall be counted toward meeting the utilization goals set forth herein as follows: 1. Subject to the other provisions of this paragraph, a bidder may count toward a dollar based utilization goal ONLY the dollar value which will actually be paid to the certified firm. 2. Whether a certified firm's utilization will be counted towards an MBG and/or WBG is determined by the certified firm's classification as an MBE, WBE, MWBE or CBE. The following classifications shall be counted toward the following goals: a. Participation by an MBE will be counted only toward the MBG. b. Participation by an WBE will be counted only toward the WBG. c. Participation by an MWBE will be counted towards either the MBG or the WBG, but not to both;the bidder shall designate the goal to which the dollar value is applied. d. Participation by a CBE shall be counted by dividing the total dollar value of the contract or portion of the contract performed by the CBE by two. One-half of the dollar value will be counted towards the MBG goal and one-half will be counted towards the WBG. 3. Joint Ventures will be counted in accordance with the provisions of paragraphs 00120- 1.07.D.,and 00120-1.08.A.2. C73130C 00120-5 M/WBE AND EEO PROGRAM REQUIREMENTS 1.09 DETERMINING COUNTABLE DOLLAR VALUE OF UTILIZATION A. The dollar value of the participation by a certified firm that will be counted towards dollar value based utilization goals(such as percentage goals) depends upon the type of work category(ies) the certified firm's work falls under. A certified firm's scope of work must fall within one or more of the following type-of-work categories in order to be counted. Except as provided in subparagraphs B through E of this paragraph 00120-1.09, the dollar value of the participation shall be counted as indicated in paragraph 00120-1.08. 1. MANUFACTURER: A bidder shall count the entire dollar value which will be paid to a manufacturer that is a certified firm (i.e. a firm that produces goods from raw materials or substantially alters theme before resale). 2.

A regular dealer in such bulk items as steel,cement,gravel,stone and petroleum products need not keep such products in stock,if it: a) owns or operates distribution equipment; and b) independently procures and delivers such bulk items (i.e. the firm must directly handle and be responsible for the product at some point in the process.) 3. PURCHASER AND INSTALLER:A bidder shall count the entire dollar value which will be paid to a certified firm who is not a manufacturer or regular dealer, but who purchases and installs goods, materials or equipment. A certified firm purchaser and installer will be considered to be performing a commercially useful function when the certified firm: a) by its installation activity adds substantive value to the goods, materials or equipment installed; and b) has the actual and contractual responsibility to purchase and install the goods,materials or equipment, and c) where the goods,materials or equipment require more than one trade to install, or the installed item needs to be tested or commissioned, the certified firm shall have the responsibility to coordinate, direct and participate in the installation-related services provided by other trades, and in the testing and commissioning. 4. SUPPLIER: A bidder shall count ONLY twenty percent (20%) of the dollar value which will be paid to a certified firm which is a supplier who is not a manufacturer or regular dealer. A certified firm supplier will be considered performing a commercially useful function in the supply process when the function or service is one which is customarily performed as a distinct and necessary part of the supply process and when the certified firm supplier: a. Assumes the actual and contractual responsibility for furnishing the materials; and b. Delivers the materials. 5. INSTALLER: A bidder shall count the entire dollar value (including but not limited to the cost of labor, materials and supplies, and markups) of the work to be performed by a firm that will install equipment and goods that will be furnished to it by another firm. The bidder shall not count the cost of the equipment and goods supplied by the other firm unless that firm is a certified firm,in which case the other firm's utilization will be counted separately under the appropriate type of work category. B. 1. The cost of concrete pumping services (not including the cost of the ready-mixed or wet concrete pumped, which is provided for in subparagraph B.2 below), may be counted toward meeting the uflization goals only if each of the following conditions is met: a. The certified firm will perform a commercially useful function as defined in paragraph 00120-1.02. b. The certified firm owns the concrete pumping equipment or leases such equipment from a source that sells or leases such equipment as its principal business activity, and seller or leasing fiim is nototherwise engaged in providing-concrete pumping services. c. The certified firm will use employees normally employed by and under the control of the certified firm to operate the concrete pumping equipment, or will obtain personnel to operate such C73130C 00120-6 MAYBE AND EEO PROGRAM REQUIREMENTS equipment from a source which provides such personnel as its principal business activity and does not provide concrete pumping services. 2. If concrete pumping services are counted as meeting the conditions of paragraphs 00120- 1.02 and 1.09, the cost of ready-mixed or wet concrete may only be counted as a part of providing concrete pumping services if the certified firm is the manufacturer of the concrete, or the certified firm purchases the concrete from another certified firm that is the manufacturer of the concrete. C. As a part of a purchase and install scope of work,the cost of ready-mixed or wet concrete may be counted toward meeting the utilization goals only if each of the following conditions is met: 1. The certified firm will perform a commercially useful function as defined in paragraph 00120-1.02;and 2. The certified firm's scope of work will include, at a minimum, the actual and contractual responsibility for purchasing, forming, placing and finishing the concrete. The certified firm may subcontract portions of the scope of work to other certified firms. D. If the cost of ready-mixed or wet concrete is not counted because the conditions set forth in subparagraph 00120-1.09C.2 are not met, the cost of labor and other costs associated with the installation tasks performed by the certified firm will be counted if the certified firm will perform a commercially useful function. E. Questions regarding whether a certified firm will be considered a manufacturer, regular dealer, purchaser and installer, supplier, or installer should be directed to King County's M/WBE and Contract Come liance Division prior to submittal of a bid for this Contract. 1.10 REASONS FOR NOT COUNTING PARTICIPATION BY A CERTIFIED FIRM A. Participation by certified firms will not be counted toward the fulfillment of utilization goals in circumstances which would contradict or tend to defeat the purposes and policies of King County Ordinance 12026',such as,but not limited to,the following: 1. If,prior to bid submittal, the proposed certified firm did not submit a bid or proposal or otherwise commit to perform work under this Contract with the bidder;or 2. If the proposed certified firm will not perform a commercially useful function as defined in paragraph 00120-1.02 and as specifically defined for individual type-of-work categories in paragraph 00120- 1.09 1 Participation by certified firms whereby the certified firm will act only as a broker (unless such is consistent with normal industry practice) or as a passive conduit to provide goods or services shall not be considered as commercially useful functions for purposes of meeting these requirements;or 3. If the proposed certified firm acts or operates in a manner inconsistent with the requisite ownership and control by the minority or women business owner(s);or 4. If it is apparent to King County that the certified firm does not understand the work it is identified to perform as demonstrated by a lack of knowledge of the following items: the scope and duration of the work, labor, equipment, materials and other resources necessary to perform the work; magnitude and duration of the work; interrelationship of the work to other aspects of the project; contents or methods of computing its bid price. B. SUBCONTRACTS TO NON-CERTIFIED FIRMS: The dollar value of any portions of the work (excluding the procurement of materials and supplies) that a certified firm will contract to other than another certified firm,regardless of tier,will not be counted toward the applicable MBG or WBG goal. C. RELIANCE ON OTHER FIRMS: A certified firm that relies to a significant extent on a non- certified firm or contracts a significantly greater portion of the work than would be expected on the basis of normal industry practice will be presumed not to be performing a commercially useful function.The certified firm may present to King County evidence to rebut this presumption. D. SALES AND MARKETING CONTRACTS:Contracts with sales,marketing and similar types of representatives shall not be considered a commercially useful function and will not be counted toward the utilization goals. C73130C 00120-7 M/WBE AND EEO PROGRAM REQUIREMENTS 1.11 SUBSTITUTION REQUIREMENTS A. The bidder shall substitute certified firms at no additional cost to King County,for certified firms excl ded by King County for reasons outside of the knowledge or control of the bidder as stated below,when the rema'ning certified firms listed by the bidder do not meet or exceed the utilization goals.If this occurs, the bidder will Substitute certified firms so that the utilization of certified firms continues to meet or exceed all of the utilization goals set forth in this contract.

In the event such bidder reasonably and justifiably relied on substantive assurances by a certi 'ed firm projected to participate hereunder relating to that firm's performance of a commercially useful function but such assurances were false, incomplete or in error and the certified firm is determined by King County prior to award of this Contract not to be performing a commercially useful function as defined herein. What constitutes a "substantive assurance" will be determined by King County on a case by case basis,but may inclu ie assurances related to qualifications,supply arrangements or other statements of specific abilities designed to lead the bidder into believing the firm will perform a commercially useful function. Generic statements such as "I can do it"do not constitute a substantive assurance which the bidder may rely upon.;or 3. r In the event such bidder proposed to use a certified firm which, subsequent to bid submittal and for reasons other than those within the control of the bidder, is unable or unwilling to perform as projected;or 4. In the event such bidder reasonably and justifiably relied upon the assurances of a proposed certified firm that the portion of work to be counted toward the MBG or WBG goal would not be further subcontracted to non-certified businesses,but prior to the award of this contract,King County determines that the certified firm will further subcontract a portion of the work to a non-certified firm;or 5. If none of the conditions in paragraph 00120-1.11B apply. B. THE BIDDER WILL NOT BE REQUIRED BY KING COUNTY OR PERMITTED UPON BIDDER'S REQUEST to substitute certified firms for certified firms excluded by King County for reasons within the knowledge or control of the bidder as stated below.

Example 2: the bidder obtains subcontractors or supp iers for the certified firm;or 3. The bidder fails to inquire as to the certified firm's qualifications,experience or abilities to perform the work prior to listing the firm and the certified firm is not capable of performing the work;or 4. The bidder does not provide the certified firm with a commercially useful function;or 5.

Just and reasonable value for such defective work will be determined by the Engineer and appropriate deductions will be made in the payments due or to become due to the Contractor. Acceptance will not act as a waiver of King County's right to recover from the Contractor an amount representing the deduction for retention of defective work. 4.10 MATERIALS AND EQUIPMENT FURNISHED BY KING COUNTY Materials and equipment, if any, specified in the Specifications to be furnished by King County shall be installed by the Contractor. Furnishing of material and equipment by King County will be considered conclusive evidence of their acceptability for the purpose intended. If the Contractor discovers defects in,material or equipment furnished by King County,the Contractor shall immediately notify the Engineer in writing. After such discovery,the Contractor shall not proceed with work involving King County-furnished materials and equipment unless otherwise authorized by the Engineer. Unless otherwise noted or specifically stated, materials and equipment furnished by King County, which are not of local occurrence, are considered to be "FOB" railroad station or truck terminal nearest to the site of the work. The Contractor shall promptly unload, transport, store and protect such material and equipment from damage. The Contractor shall inspect such King County-furnished material and equipment on receipt and provide the Engineer with written acceptance for the incorporation of said material and equipment into the work. After receipt by the Contractor at the point of delivery, King County- f mished material and equipment shall form part of the work for purposes of the Contract, including risk of loss and damage,as if it had been supplied and stored by the Contractor.

If the defective work cannot be corrected, or if the corrected work has been rejected by King County, the Contractor shall promptly remove it from the site and replace it with non-defective work, all at no cost to King County. King County is hereby authorized to make such corrections if, ten days after giving of such notice to the Contractor, the Contractor has failed to make or undertake the corrections or removal/replacement with due diligence. In case of an emergency where, in the opinion of the Engineer, delay could cause serious loss or damage, corrections or replacement may be made prior to or concurrent with notice being sent to the Contractor. All expenses in connection with such corrections or replacement, including costs for professional services, will be charged to the Contractor. For defective work either corrected or replaced, this guarantee shall be extended for a period equal to the time of correction or replacement. For the purpose of this paragraph 00710-4.11, acceptance of the work shall not extinguish any covenant or agreement on the part of the Contractor to be performed or fulfilled under this Contract which has not, in fact, been performed or fulfilled at the time of such acceptance. All covenants and agreements shall continue to be binding on the Contractor until they have been fulfilled. The guarantee provided in this paragraph 00710-4.11 shall be in addition to those specific guarantee or warranty requirements for particular equipment and/or work items indicated in the Specifications, and in addition to any other rights or remedies available to King County under this Contract or at law. 4.12 WARRANTY OF TITLE No material,supplies,equipment or items for the work shall be purchased subject to any chattel mortgage or under a conditional sale or other agreement by which an interest therein or in any part thereof is retained by the seller or supplier.

Neither the Contractor nor any person, firm, or corporation furnishing any material or labor for any work covered by this Contract shall have any right to lien upon any improvement or appurtenance thereon. Nothing contained in this paragraph 00710-4.12,however, shall defeat or impair the right of the persons furnishing materials or labor to recover under any bond given by the Contractor for their protection or any rights under any law permitting such persons to look to funds due the Contractor in the hands of King County. The provisions of this paragraph 00710-4.12 shall be inserted or referenced in or otherwise made a part of all subcontracts and material contracts, and notice of its provisions shall be given to all persons furnishing materials for the work when no formal contract is entered into for such materials.

In case any suit or legal proceedings shall be brought against King County or any of its officers, principals, agents or employees on account of loss or damage sustained by any person or property as a result of the performance of this Contract, whether or not such injuries or damage be due to the negligence of the Contractor and whether or not such injuries or damage be caused by the inherent nature of the work specified, the Contractor agrees to assume the defense thereof and to pay all expenses connected therewith and all judgments that may be obtained against King County or any of its officers, principals, agents or employees in such suits or legal proceedings. In the event that any lien is placed upon the property of King County or any of its officers, principals, agents or employees as a result of such suits or legal proceedings, the Contractor agrees to at once cause the same to be dissolved and discharged by giving bond or otherwise. • Certain kinds of incidents may result in claims which create special problems for King County. Therefore, in addition to the amounts required by Chapter 60.28 RCW to be withheld from the progress payments to the Contractor, if the Contractor or its insurance carrier does not respond in a reasonable time or manner, King County may, in its sole discretion, (1) withhold amounts sufficient to pay the amount of any property damage or bodily injury claim and/or (2) pay any property damage claim of which King County may have knowledge, regardless of the informalities of notice of such claim, arising out of the performance of this Contract.

During periods when weather or other conditions are unfavorable for construction, the Contractor shall pursue only such portions of the work as will not be damaged thereby; no portions of the work shall be constructed while those conditions exist if acceptable quality or efficiency will be adversely affected. It is expressly understood and agreed by and between the Contractor and King County that the Contract Time for completion of the work described herein is a reasonable time taking into consideration the weather conditions and other factors prevailing in the locality of the work. C73130C 00710-26 GENERAL CONDITIONS B. CONSTRUCTION SCHEDULE The Contractor shall provide progress schedules, cash flow projections and additional reports, as s ecified in the Specifications, demonstrating the Contractor's logic and sequencing plan for scheduling and completing the work within the Contract Time.Contract Time extensions approved by the King County Executive shall be incorporated into updated schedules reflecting their effect at the time of occurrence.

The Contractor shall promptly notify the Engineer in writing of any facts or conditions which wDuld affect the Contractor's ability to meet the intermediate or final completion date(s) for the work. If the Contractor fails to maintain the progress necessary for the completion of the intermediate or final completion da.te(s) as required under this Contract, King County shall have all of the rights and remedies provided by law ar d under this Contract.

C. DELAYS 1. Notice of Delays. Immediately (but in any event no more than three days) after the C ntractor foresees or should foresee a delay in the prosecution of the work or upon the occurrence of a delay w 'ch the Contractor regards as unavoidable,the Contractor shall notify the Engineer in writing of the probability o the occurrence of such delay, the extent of the delay, the specific impacts and effects of the delay on the c nstruction schedule,and its possible cause.The Contractor shall take immediate steps to prevent,if possible,the o currence or continuance of the delay. If this cannot be done, the Engineer will determine how long the delay w ll continue and to what extent the prosecution and completion of the work are being or will be delayed thereby. e Engineer will also determine whether the delay is to be considered avoidable or unavoidable and notify the C ntractor of the Engineer's determination. The Contractor agrees that no claim shall be made for the delays for w ich timely written notice to the Engineer is not made. 2. Avoidable Delays. Avoidable delays in the prosecution of the work shall include delays w ich could have been avoided by the exercise of care, prudence, coordination, foresight and diligence on the p rt of the Contractor,its subcontractors,or its suppliers at any tier. In addition,avoidable delays include,but are n t limited to: a. Delays which may in themselves be unavoidable but do not necessarily prevent o delay the prosecution of parts of the work or the completion of the whole work within the Contract Time (e.g., fit within the float time shown on the accepted construction schedule). b. Time associated with reasonable interference of King County or other contractors employed by King County which do not necessarily prevent the completion of the whole work within the C ntract Time. c. Delays which may in themselves be unavoidable, but which do not affect any cr.tical path activity on the accepted construction,schedule. 3. Unavoidable Delays: An unavoidable delay means a delay in the prosecution of the work which cannot be regarded as avoidable under paragraph 00710-6.02 C.2. Unavoidable delays shall include dlays which result from causes beyond the control of the.Contractor and which could not have been avoided by the exercise of care, prudence, coordination, foresight and diligence on the part of the Contractor, its subcontractors or its suppliers at any tier. Delays in completion of the work of other contractors employed by Kng County will be considered unavoidable delays insofar as they interfere with the Contractor's completion of tlie current controlling item on the accepted construction schedule. Delays due to abnormal weather conditions unl der paragraph 00710-8.02 will be regarded as unavoidable, but the Contractor agrees to plan its work with prludent allowances for interference by normal weather conditions. Delays caused by acts of Nature,acts of public enemy, fires, floods, epidemics, quarantine restrictions, strikes and freight embargoes will be considered as avoidable delays insofar as they prevent the Contractor from proceeding toward completion of the current c ntrolling item on the accepted construction schedule. C73130C 00710-27 GENERAL CONDITIONS D. EXTENSION OF TIME 1. Avoidable Delays. The King County Executive may grant, if requested by the Contractor,an extension of time for avoidable delay,if the King County Executive determines that an extension is in King County's best interest. If the King County Executive grants an extension of time for avoidable delay, the Contractor agrees to pay certain of King County's actual costs resulting therefrom, as specified in paragraph 00710-7.04,incurred during the extension. 2. Unavoidable Delays. For delays which the Contractor has given notice pursuant to paragraph 00710-6.02 C.1 and considers to be unavoidable, the Contractor shall submit to the Engineer complete written information demonstrating the effect of the delay on the controlling operations on the accepted c Instruction schedule. The submission shall be made within 10 days of the occurrence which. is claimed to be responsible for the unavoidable delay. The Engineer will review the Contractor's submission and determine the number of days of unavoidable delay and the effect of such unavoidable delay on such controlling operations. Tie King County Executive will grant an extension of time to the extent that unavoidable delays necessarily affect controlling operations in the construction schedule. During such extension of time, neither compensation under paragraph 00710-7.04 nor damages for delay will be charged to the Contractor.It is understood and agreed by the Contractor and King County that time extensions due to unavoidable delays necessarily involve controlling operations which would prevent completion of the work or portion thereof within the Contract Time. To the l exItent that any such extension of time is caused by act(s) or omission(s) of someone other than King County or persons acting for King County, or to the extent that the extension of time arises from a reasonable delay, the Contractor's sole remedy shall be the extension of time and it may not recover any damages whatsoever arising in anyI manner from such delay. For purposes of this paragraph, any individual delay of up to the greater of 5 days or one percent of the Contract Time (as extended) shall be deemed reasonable and any individual delay of up to the greater of 10 days or five percent of the Contract Time(as extended)shall be presumed reasonable. E. DAMAGES FOR DELAYS For each and every day that any portion of the work remains incomplete after the Contract Time, including intermediate or final completion dates, specified in the Specifications, as modified by any extension of tide granted hereunder, damage will be sustained by King County. Because of the difficulty in computing the actual material loss and disadvantages to King County, it is determined in advance and agreed by the parties hereto that the Contractor will pay King County the amount set forth in Part 8 of Section 00710 for each day of delay as representing a reasonable forecast of the actual damages which King County will suffer by the failure of the Contractor to complete such work or portion thereof within said time(s). The execution of this Contract shall constitute acknowledgment by the Contractor that it has ascertained and agrees that King County will actually suffer damages in the amount herein fixed for each and every day during which the completion of the work or portions thereof is avoidably delayed beyond the specified time(s). This paragraph shall provide the Contractor's sole remedy for any and all damages it may suffer for' delay. For unavoidable delays which are also unreasonable delays under paragraph 00710-6.02 D.2, the Contractor must make a complete and timely claim for damages referring to this paragraph. Because of the difficulty in computing the actual losses to the Contractor, it is determined in advance and agreed by the parties hereto that King County will pay the Contractor the amount set forth in Part 8 of Section 00710 for each day of unavoidable,unreasonable delay as representing a reasonable forecast of the actual damages;provided,however, that such liquidated damages will be paid only if any extension of time granted the Contractor does not fairly compensate the Contractor for such unavoidable,unreasonable delay. F. SUBSTANTIAL COMPLETION When the work under this Contract is completed to the extent that King County has full and unrestricted use and benefit of the facilities, both from the operational and safety standpoint, and only minor incidental work, replacement of temporary substitute facilities, or correction or repair remains to complete the entirety of the work,the Engineer will determine that the work is substantially complete.The Engineer will notify the Contractor in writing of the substantial completion date. For overruns in Contract Time occurring after the substantial completion, damages for delay assessed against the Contractor as provided in paragraph 00710-6.02 E not apply. For overruns in Contract Time occurring after substantial completion, damages shall be assessed against the Contractor on the basis of direct engineering, inspection, and related costs assignable to this Contract. C73130C 00710-28 GENERAL CONDITIONS The Contractor shall complete the remaining work as promptly as possible. Upon request by the Engineer, the Contractor shall furnish a written schedule for completing the remaining work. 6.03 SUSPENSION PROCEDURES The Engineer may,at any time and without cause,suspend all or any part of the work by notice in writing to the Contractor. The Contractor shall resume the work within five days after receiving written notice from the Engineer to do so. The Contractor may submit a claim,as provided in paragraph 00710-7.02,for an increase in the cost of performing the Contract or an extension of Contract Time, or both,necessarily caused by any suspension; provided, the Contractor shall not be entitled to any increase for any suspension, delay, or interruption to the extent that performance would have been so suspended,delayed,or interrupted by any other cause,including the fault or negligence of the Contractor, or for which an equitable adjustment is provided for or excluded under any other provision of this Contract, or if suspension does not affect any critical activity on the accepted construction schedule, or if the suspension is based on non-compliance with requirements under paragraph 00710-1.15. If the Engineer does not give notice in writing to the Contractor to resume work at a date within 180 days of the date of the notice to suspend, then the Contract shall be assumed to be terminated and the Contractor shall be entitled to compensation in accordance with paragraph 00710-6.04 B. 6.04 TERMINATION PROCEDURES A. TERMINATION BY KING COUNTY FOR DEFAULT The King County Executive shall act for and on behalf of King County in all termination actions an determinations. The King County Executive may terminate the Contract upon written notice to the Contractor whenever the Contractor is deemed to be in default or fails to fulfill, in a timely and proper manner, the contract obligations, or is in violation of any provisions or covenants of the Contract. Termination shall be effective upon receipt of such notice by the Contractor. The Contractor shall immediately discontinue work and take all reasonable steps with its suppliers and subcontractors to minimize cancellation and other costs.

Further, King County may exclude the Contractor from the site and take possession of the work and all of the Contractor's tools,appliances, construction equipment and machinery at the site and use them in the completion of the work to the full extent they could be used by the Contractor. Materials and equipment for which King County has paid any amount on to the Contractor may be incorporated in the work regardless of whether they are stored at the site or stored elsewhere.In such cases,the Contractor will not be entitled to receive any further payment until all work is finished.The Contractor shall only be entitled to payment for portions of the work satisfactorily completed prior to termination for default. If the cost to complete the work,including compensation for additional professional services,is in excess of the unpaid balance to the Contractor,the Contractor shall pay the difference to King County. C73130C 00710-29 GENERAL CONDITIONS Where the Contract has been so terminated by the King County Executive, the termination shall not affect any rights of King County against the Contractor then existing or which may thereafter accrue. Any retention or payment of moneys due the Contractor by King County will not release the Contractor from liability.

The prepared surface shall also be free of fins, projections, thin crusts, bridging voids, loosely adhering concrete and dirt particles. Fins and projections shall be removed. Irregular surfaces and tie holes shall be filled with grout in accordance with Section 03300. 2. The surface shall be sand blasted or remove the surface mortar and just expose the surface of some of the coarse aggregate. B. Inspection Testing 1. The prepared surface shall be visually inspected by the Engineer to identify fins, projections, thin crusts, bridging voids, loosely adhering concrete, and contaminants prior to applying co-lining system. 2. The pH of the prepared surface will be tested in accordance with ASTM D4262 prior to application of co-lining primer. The acceptable pH range of the prepared surface shall be 7 to 11. 3. The prepared concrete surface shall be tested by Swiss impact hammer or other physical method. 3 04 APPLICATION A. Proportioning and Mixing 1. Mastic and activator shall be mixed and proportioned in accordance with, the manufacturer's written instructions with the equipment specified by the manufacturer. B. Primer 1. The epoxy/urethane primer shall be applied to the dry, sound concrete surface at a rate not to exceed 250 square feet per gallon of primer. Allow the primer to cure to tack dry before the mastic is applied. Application of the primer shall precede the mastic application by no more than one hour. C. Mastic 1. Mastic shall be applied to a prepared dry, sound surface. Mastic shall be directly applied to the prepared surface with a trowel. Mastic coverage shall not exceed 13 square feet per gallon, and shall provide a minimum thickness of 120 mils and a maximum of '/.-inch thickness for existing concrete rehabilitation. For new concrete, do not exceed 25 square feet per gallon and a minimum thickness of 60 mils. D. Activator 1. Apply activator to clean, dry PVC sheet in accordance with manufacturer's instructions. Allow to cure to "tack" stage for CLA-1 and "tack-free" for CLA-2 prior to embedding PVC sheet in mastic. Activator shall be applied to sheet in a warm, (70 degree F minimum), protected environment and allowed to dry prior to shipment to the job site. Protect prepared sheet from debris contamination. E. Seam Material 1. Seam material shall be applied to the 4"wide overlap areas of activated PVC sheet liners. The trowel applied material coverage shall not exceed 75 linear feet per gallon. C73130C 09880-5 Bryn Mawr System Improvements Bryn Mawr Trunk Replacement F. Sheet Liner 1. The activator-prepared surface of the PVC sheet liner shall be pressed into the mastic and rolled to remove trapped air. Seams shall overlap a minimum of 4 inches. Vertical seams shall have liner material overlapped in the direction of the flow, and shall be fully bonded in the mastic to the adjoining sheet. Horizontal seams shall overlap the adjoining lining sheet below. Premolded corners shall be used at all interior and exterior corners, and shall be fully lapped (3 inches) with the lining sheets. The average dry film thickness of the cured protective lining system shall not be less than 150 mils for concrete rehabilitation and 90 mils for new concrete. Maximum size sheet applied in a single piece shall not exceed 8 feet in any dimension without prior approval by the Engineer. PVC sheet shall be applied while the mastic is still tacky. G. Termination of Liner 1. Terminate PVC liner as recommended by the manufacturer. See Linabond Standard Detail Drawings. H. Atmospheric Conditions . 1. Maintain sufficient forced air supply and construction heating to provide a minimum of 70 degrees F and 3 feet per second airflow inside the structure during the lining process. Airflow shall be maintained whenever personnel are in the structure. I. Inspection and Testing 1. After installation, the surface of the liner will be visually inspected by the Engineer for areas of poor adhesion, air pockets over 8-inches in diameter, edge or seam defects, rips, tears, and punctures. The Engineer will also perform random peel tests on each day's production, similar to the procedures outline in ASTM C794, to determine adhesion. Each peel test is a destructive test which will require patching at Contractor expense. Additional tests may be required if the minimum resistance of 16-pounds per lineal inch adhesion has not developed. A full description of the test can be found in the Manufacturer Inspectors Guide, which may be viewed at the Contracts Counter, 12th Floor, Exchange Building. Provide access to the work, including scaffolding, as needed to facilitate testing and inspection. J. Repair of Defects 1. Repair defects in the lining system where directed by the Engineer. Trim damaged areas. Cut open large air pockets and apply new mastic and activator, imbed cut ends in new mastic, and overlay with PVC patch. Activate PVC surfaces with instant cross-link activator CLA-2 as manufactured by Linabond, Inc. Patching: cover with new mastic and activate PVC sheet, lapping all edges of the repair'a minimum of 4-inches. This repair technique shall be used for patching the areas removed during peel tests in Paragraph 09800-3.04F above.
