[03003-0104/8B022180.328] 8/12/02 DEVELOPMENT AGREEMENT BETWEEN THE BOEING COMPANY AND THE CITY OF RENTON FOR FUTURE DEVELOPMENT OF LONGACRES OFFICE PARK I. PREAMBLE This DEVELOPMENT AGREEMENT ("Agreement")between THE BOEING COMPANY("Boeing"), a Delaware corporation, and the CITY OF RENTON("City"), a municipal corporation of the State of Washington, is entered into pursuant to the authority of RCW 36.70B.170 through .210, under which a local government may enter into a development agreement with an entity having ownership or control of real property within its jurisdiction. H. RECITALS A. Longacres Park, Inc. ("LPI"), a wholly-owned subsidiary of Boeing, is the owner of certain real property, known as the Longacres Office Park("LOP"), located in the City of Renton, King County, Washington, and more particularly described in Attachment 1, attached hereto and by this reference incorporated herein. LPI and Boeing have entered into a long-term Ground Lease("Lease")with effect from January 1, 1993 pursuant to which Boeing may possess LOP through December 31, 2027 and may in certain circumstances extend the term of said lease through December 31, 2057. Pursuant to the Lease, Boeing may enter into this Agreement in Boeing's own name. A memorandum of the Lease was recorded as No. 9707030128 in the Real Property Records of King County. • B. LOP consists of approximately 158 acres located at the southeast corner of the intersection of Interstate 405 and the Burlington Northern Santa Fe Railroad right of way in the City of Renton. Boeing's Customer Service Training Center ("CSTC") occupies an adjacent 48-acre site to the north and east of LOP. LOP is currently located entirely within the Commercial Office("CO")zoning district and is designated Employment Center-Valley in the City's Comprehensive Plan. C. The site plan for the Longacres Office Park("LOP Site Plan") includes the construction of approximately 3 million square feet of office or light industrial space as permitted under the CO designation and related support and utility facilities over a period of up to twenty(20)years. Of the 158 acres comprising the LOP site, the LOP Site Plan proposes that approximately 65 percent will be impervious surface (i.e., buildings, parking areas or parking structures, and roadways), and approximately 35 percent will be dedicated to a stormwater detention system, landscaping and open space. The LOP Site Plan is attached to this Agreement as Attachment 2 and by this reference is incorporated herein. DEVELOPMENT AGREEMENT PAGE 1 [03003-0104/SB022180.3281 8/12/02 D. Environmental analysis of development of 2.5 million square feet under the LOP Site Plan was conducted by the City pursuant to the Washington State Environmental Policy Act ("SEPA"). A Draft Environmental Impact Statement ("DEIS") for the LOP Site Plan was issued in August, 1994; the Final Environmental Impact Statement("FEIS")was issued in March, 1995; an Addendum to the FEIS, analyzing the impacts of, among other things, the addition of 500,000 square feet to the LOP Site Plan, was issued in December, 2000. A SEPA Mitigation Document("Mitigation Document")was issued by the-City in May, 1995, and was amended by the Addendum. E. In 1997, Boeing developed the Boeing Commercial Airplane Group ("BCAG") headquarters office building, consisting of approximately 300,000 square feet, as Phase I of LOP. The location and extent of Phase I development is depicted on Attachment 2. F. In 1998, Boeing developed the Boeing Family Care Center("FCC"), consisting of approximately 22,000 square feet to provide day care services for 200 children as Phase II of LOP. The location and extent of Phase II development is depicted on Attachment 2. G. In 1999, Boeing developed a Surface Water Management Program ("SWMP"), consisting of grading to create stormwater ponds, an irrigation, aeration, and recirculation system, and enhanced wetlands designed to accommodate full build-out of LOP. The location and extent of Phase III development is depicted on Attachment 2. H. As part of the SWMP project, certain critical environmental areas on the Longacres site were identified. These areas include certain enhanced wetlands and the South Marsh. On July 6, 1999,Boeing recorded a Declaration of Restrictive Covenants prohibiting development or alteration of the 10.92-acre South Marsh;the South Marsh is depicted on Attachment 2. I. Phase IV of the Longacres Office Park will consist of the development of approximately 2.7 million square feet of office or light industrial space as permitted under the CO designation, with support and utility facilities, on that portion of LOP not developed under Phases I, II, and III or reserved for environmental mitigation purposes pursuant to development conditions. Phase IV will be developed with multiple buildings and associated parking, roadways, and pedestrian walkways. The Phase IV development capacity is consistent with the capacity analyzed in the existing DEIS, FEIS, and Addendum. The Phase IV development envelope is depicted on Attachment 2. J. In order to provide certainty and efficiency with respect to the City's review and approval process for Phase IV development, Boeing and the City entered into a Development Agreement("2000 Agreement") on December 28, 2000 regarding Phase IV DEVELOPMENT AGREEMENT PAGE 2 [03003-0104/SB022180.3281 8/12/02 development, recorded as No. 20010104000886 in the Real Property Records of King County. K. On $F-GE M 14,a -the City approved a binding site plan, recorded as No 2 036W/o0,2Ver in the Real Property Records of King County, that divides Phase IV into multiple parcels for future development. Accordingly, Boeing and the City desire to rescind the 2000 Agreement and to enter into a new Development Agreement governing Phase IV development. Therefore,Boeing and the City agree as follows: III. AGREEMENT 1. Vesting and Term of Agreement.

Notwithstanding the foregoing, the City reserves the authority under RCW 36.70B.170(4)to impose new or different regulations to the extent required by a serious threat to public health and safety, as determined by the Renton City Council after notice and an opportunity to be • heard has been provided to Boeing. 2.

This Agreement amends the Mitigation Document as follows: 3.1.

To the extent that Section 2, Mitigation Plan, references or incorporates development regulations, they shall be as provided and defined in Paragraphs 1 and 2 of this Development Agreement. 4. Site Plan Review and Minor Modifications. Phase IV development permit applications shall be subject to the City land use review process under the development regulations applicable to such review and approval as provided in Paragraphs 1 and 2 of this Agreement.

PREAMBLE This DEVELOPMENT AGREEMENT ("Agreement") between THE BOEING COMPANY ("Boeing"), a Delaware corporation, and the CITY OF RENTON ("City"), a municipal corporation of the State of Washington, is entered into pursuant to the authority of RCW 36.70B.170 through .210, under which a local government c may enter into a development agreement with an entity having ownership or control of real property within its jurisdiction. C3 H. RECITALS A. Boeing is the owner of certain real property, known as the Longacres Office Park ("LOP"), located in the City of Renton, King County, Washington, and more particularly described in Attachment 1, attached hereto and by this reference incorporated herein. B. LOP consists of approximately 158 acres located at the southeast intersection of Interstate 405 and the Burlington Northern Railroad tracks in the City of Renton. Boeing's Customer Service Training Center ("CSTC") occupies an adjacent 48-acre site to the north and east of LOP. LOP is located entirely within the Commercial Office ("CO") zoning district and is designated Employment Center- Valley by the City's Comprehensive Plan. C. The master plan for LOP ("Master Plan") includes the construction of approximately 3 million square feet of office or light industrial space, related support and utility facilities, and open space amenities over a period of up to 15 years. Approximately 15 separate buildings would occupy the site upon completion. Of the 158 acres comprising the LOP site, the Master Plan proposes that approximately 79 acres will be impervious surface (i.e., buildings, parking areas or parking structures, and roadways), approximately 11 acres will be dedicated to a stormwater detention system, and approximately 68 acres will be devoted to landscaping and open space. The Master Plan is attached to this Agreement as Attachment 2 and incorporated herein by reference. D. Environmental analysis of development of 2.5 million sq. ft. under the Master Plan of the State Environmental Policy Act ("SEPA") was conducted by the City. A Draft Environmental Impact Statement ("DEIS") for the Master Plan was , issued in August, 1994; the Final Environmental Impact Statement ("FEIS") was issued in March, 1995. A SEPA Mitigation Document ("Mitigation Document") was issued by the City in May, 1995. E. In 1997, Boeing developed the Boeing Commercial Airplane Group ("BCAG") headquarters office building, consisting of approximately 300,000 square feet, as Phase I of LOP. The location.and extent of Phase I development is depicted on Attachment 2. F. In 1998, Boeing developed the Boeing Family Care Center ("FCC"), consisting of approximately 22,000 square feet to provide day care services for 200 children as Phase II of LOP. The location and extent of Phase II development is depicted on Attachment 2. �:. G. In 1999, Boeing developed a Surface Water Management Program ("SWMP"), consisting of grading to create stormwater ponds, an irrigation, aeration, and recirculation system, and enhanced wetlands designed to accommodate full build- out of LOP. The location and extent of Phase III development is depicted on Attachment 2. H. As part of the SWMP project, certain critical environmental areas on the Longacres site were identified. These areas include certain enhanced wetlands, the South Marsh, and a wildlife corridor to be generally located between SWMP and the Marsh. On July 6, 1999, Boeing recorded a Declaration of Restrictive Covenants prohibiting development or alteration of the 10.92-acre South Marsh. Site wetlands (including South Marsh) and the area within which a wildlife corridor area will be located are depicted on Attachment 2. , I. Phase IV of the Longacres Office Park will consist of the development of approximately 2.7 million square feet of office or light industrial space, with support and utility facilities, on that portion of LOP not developed under Phases I, II, and III or reserved for environmental mitigation purposes pursuant to development conditions. The Phase IV development will be constructed in multiple, campus-style buildings, with parking, roadways, and pedestrian walkways. The Phase IV development envelope is depicted on Attachment 2. J. Boeing and the City agree that Phase IV should be regulated and mitigated in order to provide certainty and efficiency with respect to the City's review and approval process for that development. Accordingly, Boeing and the City agree as follows: III. AGREEMENT 1. Vesting and Term of Agreement. The City's development regulations in effect and applicable to project applications as of the date of recording of this Agreement shall govern the development of Phase IV of LOP for all Phase IV development applications submitted to the City within 15 years from the recording date of this Agreement. Notwithstanding the foregoing, the City reserves the authority under RCW 36.70B.170(4) to impose new or different regulations to the extent required by a serious threat to public health and safety, as determined by the Renton City Council after notice and an opportunity to be heard has been provided to Boeing. 2.

Applicable development regulations are attached to this Agreement as C, Attachment 3 and incorporated herein by reference. For purposes of the Agreement, the zoning designation for the property is Commercial Office (CO) pursuant to the 2000 Zoning Map as adopted by the City Council. 3. Mitigation Document. This Agreement amends the Mitigation Document as follows: (a) Section 1, General Information, second paragraph is amended to read: As indicated in the EIS, numerous state and local regulations will govern development of Longacres Office Park and application of those regulations will also serve to mitigate certain significant adverse environmental impacts.

CITY OF RENTON Planning/Building/Public Works MEMORANDUM DATE: November 20, 2000 TO: Kathy Keolker-Wheeler, Planning & Development Committee Chair City Council Members VIA: Mayor Jesse Tanner FROM: Gregg Zimmerman, Administrator G STAFF CONTACT: Lesley Nishihira, Development/Planning, x7270 SUBJECT: Boeing Longacres Office Park Development Agreement ISSUE: The Boeing Company has proposed a Development Agreement in order to establish applicable development regulations, including a vesting framework and other restrictions, for the Boeing Longacres Office Park (LOP) development project. RECOMMENDATION: Staff recommends Council approve the Development Agreement and adopt the Resolution. BACKGROUND SUMMARY: The Boeing Company has requesting the approval of a Development Agreement in order to establish applicable development regulations, including a vesting framework and other restrictions, for the Boeing Longacres Office Park (LOP) development project. The Development Agreement is based on the adopted 1994 LOP Environmental Impact Statement (EIS) and 1995 Mitigation Document, as well as modifications to the LOP development proposal as established by the Addenda process. The adopted EIS and Mitigation Document described the environmental impacts of a 164-acre, 2.5 million square foot phased master planned development, including offices, an employee center, related support and utility facilities, and open spaces amenities. The current proposal is to increase the total gross square footage of building area by 500,000 square feet. This would be accomplished by increasing the height of the proposed buildings while remaining within the range of heights analyzed in the scope of the EIS. An Addendum to the adopted EIS, as well as the Mitigation Document, which would update the proposal for which the previous EIS was conducted is currently under review. Prior to issuing the Addendums, the Environmental Review Committee (ERC) will determine whether or not the updated proposal would substantially change the analysis • • of significant impacts and alternatives contained within the existing documents. If the ERC determines there would be no significant change in the analysis, the Addendums will be issued pursuant to WAC 197-11-625 and WAC 197-11-706. The proposed Development Agreement would be adequately covered under the umbrella of the analysis contained within the adopted EIS and Addendums. As established by RCW 36.70B.190-200, the Development Agreement must be approved by the City through ordinance or resolution after a public hearing is held. The Development Agreement must then be recorded with King County once the ordinance or resolution is in effect. Attached is a draft version of the Development Agreement and Resolution. These documents are currently being reviewed by City Staff and the City Attorney. Initial comments indicate the need for revisions, including the addition of language that precludes the development from vesting to life-safety regulations (e.g., Uniform Building Code, Fire Prevention Regulations). Prior to the public hearing, revised documents will be circulated for final review. Future LOP development proposals will be individually reviewed under SEPA Rules and City of Renton policies and regulations applicable to the planned office park development and would be required to be consistent with the approved Development Agreement. cc: Neil Watts, Development Services Director Jennifer Henning, Principal Planner Lesley Nishihira, Associate Planner • EXHIBIT A DEVELOPMENT AGREEMENT BETWEEN THE BOEING COMPANY AND THE CITY OF RENTON FOR FUTURE DEVELOPMENT OF LONGACRES OFFICE PARK I. PREAMBLE This DEVELOPMENT AGREEMENT("Agreement")between THE BOEING COMPANY ("Boeing"), a Delaware corporation, and the CITY OF RENTON ("City"), a municipal corporation of the State of Washington, is entered into pursuant to the authority of RCW 36.70B.170 through .210, under which a local government may enter into a development agreement with an entity having ownership or control of real property within its jurisdiction. II. RECITALS . A. Boeing is the owner of certain real property,known as the Longacres Office Park("LOP"), located in the City of Renton, King County, Washington, and more particularly described in Attachment 1, attached hereto and by this reference incorporated herein. B. LOP consists of approximately 158 acres located at the southeast intersection of Interstate 405 and the Burlington Northern Railroad tracks in the City of Renton. Boeing's Customer Service Training Center("CSTC") occupies an adjacent approximately 48-acre site to the north and east of LOP. LOP is located entirely within the Commercial Office("CO") zoning district and is designated Employment Center-Valley by the City's Comprehensive Plan. C. The master plan for LOP ("Master Plan") includes the construction of approximately 3 million square feet of office or light industrial space, related support and utility facilities, and open space amenities over a period of up to 15.years. Approximately 15 separate buildings would occupy the site upon completion. Of t9he 158 acres comprising the LOP site,the Master Plan proposes that approximately acres will be impervious surface (i.e., buildings, parking areas or parking structures, and roadways), approximately 11 acres will be dedicated to a stormwater detention system, and approximately 68 acres will be devoted to landscaping and open space. The Master Plan is attached to this Agreement as Attachment 2 and incorporated herein by reference. • 9/29/00 [03003-0150/Development Agreement.doc] D. Environmental analysis of development of 2.5 million sq. ft. under the Master Plan of the State Environmental Policy Act("SEPA") was conducted by the City to the requirements. A Draft Environmental Impact Statement("DEIS") for the Master Plan was issued in August, 1994; the Final Environmental Impact Statement ("FEIS") was issued in March, 1995. A SEPA Mitigation Document ("Mitigation Document") was issued by the City in May, 1995. E. In 1997, Boeing developed the Boeing Commercial Airplane Group ("BCAG") headquarters office building, consisting of approximately 300,000 square feet, as Phase I of LOP. The location and extent of Phase I development is depicted on:Attachment 2. F. In 1998, Boeing developed the Boeing Family Care Center ("FCC"), consisting of approximately 22,000 square feet to provide day care services for 200 children as Phase II of LOP. The location and extent of Phase II development is depicted on Attachment 2. G. In 1999, Boeing developed a Surface Water Management Program ("SWMP"), consisting of grading to create stormwater ponds, an irrigation, aeration, and recirculation system, and enhanced wetlands designed to accommodate full build- out of LOP and associated CSTC site. The location and extent of Phase III development is depicted on Attachment 2. H. As part of the SWMP project, certain critical environmental areas on the Longacres site were identified. These areas include certain enhanced wetlands, the South Marsh, and a wildlife corridor to be generally located between SWMP and the Marsh. On July 6, 1999, Boeing recorded a Declaration of Restrictive Covenants prohibiting development or alteration of the 10.92-acre South Marsh. Site wetlands (including South Marsh) and the area within which a wildlife corridor area will be located are depicted on Attachment 2. I. Phase IV of the Longacres Office Park will consist of the development of approximately 2.7 million square feet of office or light industrial space, with support and utility facilities, on that portion of LOP not developed under Phases I, II, and III or reserved for environmental mitigation purposes pursuant to development conditions. The Phase IV development will be constructed in multiple, campus-style buildings, with parking, roadways, and pedestrian walkways. The Phase IV development envelopes is depicted on Attachment 2. J. Boeing and the City agree that Phase IV should be regulated and mitigated in order to provide certainty and efficiency with respect to the City's review [03003-0150/Development Agreement.doc] -2- 9/29/00 • and approval process for that development.

The adopted EIS Mitigation Document included mitigating measures for the environmental impacts of a 164-acre, 2.5 million square foot phased master planned development, including offices, an employee center, related support and utility facilities, and open spaces amenities. The current proposal is to increase the total gross square footage of building area by 500,000 square feet. This would be accomplished by increasing the height of the proposed buildings. The proposal has been determined to not substantially change the analysis of significant impacts and alternatives contained within the adopted LOP EIS. Therefore, addendums to the EIS and Mitigation Document have been prepared in order to update the proposal. The addendum to the adopted Mitigation Document is necessary in order to clarify specific mitigation measures in response to the incremental building area. As part of this proposal, the proponent has requested the approval of a Development Agreement in order to establish applicable development regulations, including a vesting framework and other restrictions, for the Boeing LOP development project. The Development Agreement is based on the adopted LOP EIS and Mitigation Document, as well as modifications to the LOP development proposal as established by the addenda process. -t. Amended Mitigation Measures: • Fire: The payment of a Fire Mitigation Fee in the amount of $0.52 per square foot of the 3.0 million square foot development is required on a project specific basis. The base fee may be adjusted as established in the adopted Mitigation Document with the appropriate recalculation of the projected fee amounts based on the 0.5 million square foot increase to building area. • Transportation / Roadway Improvements: 1. Upon development of office uses abutting the SW 27th Street right-of-way, Boeing will construct a local access street to Renton City standards to provide site access from Oakesdale Avenue SW. 2. Upon construction of the Strander Boulevard extension by the City of Renton, any assessments or other charges allocated to Boeing to pay for some portion of the extension shall be reduced by no less than the full cost expended by Boeing in designing and constructing the local access roadway. Of the portion of SW 27th Street extension within the boundaries of LID 314, Boeing allocated share of the cost of such portion of the extension, including water and sewer improvements, if any, shall not exceed 30 percent. • Transportation / Safety Improvements: An appropriate crossing treatment on Jackson Avenue SW shall be provided in order to minimize conflicts between vehicle traffic and employee walk access, and to provide a safe and attractive route for commuter rail patrons between the final Tukwila Multimodal Station and the Boeing Longacres Office Park site. • Transportation /Site Access and Circulation: 1. Driveway locations onto Oakesdale Avenue SW and SW 27th Street should be minimized when feasible. 2. Driveway locations and off-sets relative to adjacent intersections and driveways would be designed based on standard traffic engineering methods and practices, as well as in accordance with local guidelines. • Tukwila: A Transportation fee will be assessed by the City of Tukwila for mitigation of traffic impacts to the City of Tukwila. The terms and conditions of this assessment have been established in a separate agreement between Boeing and the City of Tukwila. Location: The northern boundary of the project site is formed generally by the Boeing Company's Customer Services Training Center. The southern boundary lies approximately 1,000 feet south of Southwest 27t Street. Oakesdale Avenue Southwest, when extended, generally forms the site's eastern border. The Burlington Northern Railroad tracks from the western boundary of the project site (and the western limits of the City of Renton). Lead Agency: City of Renton, Planning/Building/Public Works Department Review Process: Individual development proposals for the Longacres Office Park will be reviewed under City of Renton land use policies and regulations applicable to the planned office park development as of the recording date of the Development Agreement and will be required to be consistent with the adopted Development Agreement. Additional environmental review, with supplementary mitigation as appropriate, may also be required for specific site plans and/or other specific development actions. The vesting provided for by the Development Agreement applies to City of Renton land use policies and regulations to the extent provided by Washington State law.

As shown on Table 4 of the Transportation Study for Boeing Longacres Office Park assuming an increase from 2.5 million square feet to 3.0 million square feet of development, two methods of calculating trip generation were considered. One resulted in 41,900 daily trips and the other resulted in 33,000 daily trips. We were not supportive of the latter method (33,000 daily trips), but did comment to this effect since it was evident that the impact analysis and mitigation proposals in the Transportation Study were , based on the latter method (41,900 daily trips). The 41,900 daily trips are higher than the 36,200 daily trips calculated for the original EIS (also provided on Table 4) reflecting the increase in proposed development square footage. As shown on Table 4, the vehicle trip generation after applying mode split assumptions to the 41,900 daily trips was determined to be 28,000 total daily vehicle trips versus the 28,900 total daily vehicle trips calculated under the original EIS proposal. The reason that these values are similar is that in this latest transportation study: 1) the mode share for transit was increased from 7% in the original EIS to 8% to reflect the close proximity of the soon-to-be constructed Tukwila Multi-modal Station; 2) a value of 2% was assigned for Commuter Rail mode share given the Sounder station proximity and service provided (though discussed in the original EIS actual credit in numerical form was not considered in calculating vehicle trips); 3) the carpool mode share increased from 7% in the original EIS to 13% in this current study to reflect recent mode share analysis conducted fro other Boeing major office complexes in Renton resulting from implementation of TDM programs similar to what could be anticipated for forther development at the LOP site. (We concur with these assumptions.) These adjustments resulted in_a. higher mode split whichin turn resulted in a daily vehicle trip calculation similar to the original EIS even though additional development square footage is proposed. (These assumptions and calculations are shown in Table A-3, Appendix A of the Transportation Study.) The analysis of impacts in the current Transportation Study is based on 28,000 daily vehicle trips (page 23). The mitigation fee described in the Mitigation Document for the originally proposed 2.5 million square. feet of development was based on 27,000 daily vehicle trips which reflected a credit for proposed HOV usage and other TDM strategies. In this latest Transportation Study for 3.0 million square feet of development, 26,000 daily vehicle trips were calculated after applying credit for proposed HOV usage and TDM strategies. (Table A-3, Appendix.) However, the mitigation discussion in this latest Transportation Study proposes a mitigation based on the originally determined 27,000 daily vehicle trips. cc: Sandra Karl H:\TRANS\PLNG\RLM\REVIEWS BOB LONG OFFICE PARK CITY OF RENTON PLANNING/BUILDING/PUBLIC WORKS MEMORANDUM DATE: November 13, 2000 TO: Leslie Nishihira FROM: Allen Quynn SUBJECT: Long Acres Offic Park—Conceptual Drainage Plan review I have reviewed the drainage report for the Boeing Long Acres Office Park. The applicant has met all the current City requirements regarding storm detention, water quality, compensatory storage and finish floor elevations. The applicant should be advised that as the office park is developed, the project might need to meet stricter storm water standards at the time of construction permitting. These stricter storm - water standards may be new standards that have been adopted by the City in response to state or federal regulations or required by a state or federal agency as a condition of a state or federal permit required for the project's construction. That being said, the applicant may want to revise the drainage report and proposed site development plan using more stringent water quality and detention standards such as those outlined in either the 1998 King County Drainage Manual or the new Ecology Manual. The proposed project must maintain existing pass through drainage from upstream tributary areas across the site. cc: Ron Straka j v'e \\CENTRAL\SYS2\DEPTS\PBP W\DIVISION.S\UTILITIE.S\DOCS\2000-525.doc\rjs City of Renton Department of Planning/Building/Public Works ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET ;EVIEWING DEPARTMENT: PojAes COMMENTS DUE: 11/9/00 APPLICATION NO: LUA-00-130,ECF DATE CIRCULATED: 10/26/00 APPLICANT: The Boeing Company PROJECT MANAGER: Lesley Nishihira PROJECT TITLE: Boeing Longacres Office Park WORK ORDER NO: 78743 LOCATION: Boeing Longacres site/generally S of 1-405, west of Oakesdale Avenue SITE AREA: 158 acres I BUILDING AREA(gross): SUMMARY OF PROPOSAL:The City is preparing an Addendum to the 1994 Boeing Longacres Office Park Environmental Impact Statement(LOP EIS).

However, it should be noted that the southernmost portion of the site, about 18 acres, is currently zoned Resource Conservation (RC) rather than Commercial Office (CO) as it is described in the application materials. Although a portion of this area is constrained by the South Marsh, Figure C.1 indicates that a portion is also slated for future development. As the proposed development agreement is intended to vest to existing zoning,this issue may need to be addressed ahead of the agreement. Since both the CO and RC areas are designated Employment Area - Valley, a rezone would not require an amendment to the Comprehensive Plan. cc: Sue Carlson Betty Nokes \\CENTRAL\SYS2\DEPTS\FINANCE\ECON_DEV\EconomicDevelopment\STRATPLN\PLANNING\PREAPP\EAV\BoeingLA_A ddendum.doc\od Fir Nick_ (1-fzQ11- City of Renton Department of Planning/Building/Public Works ' ENVIRONMENTAL 8 DEVELOPMENT APPLICATION REVIEW SHEET EVIEWING DEPARTMENT:7mA) -)ov1 lanil COMMENTS DUE: 'I'I/9/OO APPLICATION NO: LUA-00-130,ECF DATE CIRCULATED: 10/26/00 -oo�' do APPLICANT: The Boeing Company PROJECT MANAGER: Lesley Nishihira o —a '"gy� p sP �'O " PROJECT TITLE: Boeing Longacres Office Park WORK ORDER NO: 78743 m LOCATION: Boeing Longacres site/generally S of 1-405, west of Oakesdale Avenue w� SITE AREA: 158 acres I BUILDING AREA(gross): SUMMARY OF PROPOSAL: The City is preparing an Addendum to the 1994 Boeing Longacres Office Park Environmental Impact Statement (LOP EIS).

It was then estimated that the office park would be developed over a ten to fifteen year period according to Boeing's corporate needs. In preparation for site development, Boeing now proposes to enter into a development agreement with the City pursuant to the requirements of RCW 36.70B.170 through .210. The agreement will describe the basic parameters of the proposed office park development and will be based on the 1994 EIS and additional environmental analysis of certain aspects of the project. The updated environmental analysis will also discuss any additional impacts caused by increasing the height of certain buildings to achieve a 500,000 square-foot increase in total gross floor area of the office park. This report documents programmatic transportation impacts associated with the Boeing LOP— Master Plan Update at a proposed total buildout of 3.0 million square-feet of office uses. Two separate trip generation scenarios were used to evaluate the proposed buildout of 3.0 million sf of office. These scenarios included: 1. Using methods and assumptions consistent with those documented in Chapter 14 — Transportation of the Renton/Boeing DEIS — Boeing Longacres Office Park, August 1994, accounting for mode split adjustments given the adjacent Tukwila commuter rail station and multimodal center,and built office uses in operation within the mitigation area,and 2. Using current transportation engineering methods and assumptions, and considering the adjacent Tukwila commuter rail station and multimodal center. Under either scenario, a net decrease in vehicle so'. _- . - . :on over vested buildout levels was found when evaluatingthe osed buildout o .0Asf of office es at BoeingLOP. �� J �-YVlti� fOti. Project impacts to ridership on commuter rail se - - - - ated at 400 one-way boardings during the p.m. peak hour-in the reverse commute direction, resulting in a net increase of 300 one-way daily boardings over current ridership estimates. This demand for ridership however, would be in the reverse commute direction and would not adversely impact excess passenger capacity of commuter rail operations. To minimize impacts of this ridership demand, the applicant would install an appropriate crossing treatment on Jackson Avenue SW to minimize conflicts between vehicle traffic and employee walk access, and to provide a safe and attractive route for commuter rail patrons between the Tukwila Multimodal Station and Boeing LOP. The project applicant would also implement traditional transportation demand management (TDM) programs through a series of parking management strategies, subsidy elements and incentives, site amenities, work schedule and other special programs and operations to reduce project impacts during peak commute periods and meet Commute Trip Reduction (CTR) requirements.

September 29,2000 Transportation Engineering Northwest,LLC Page 12 i . r i, Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Sound Transit and King-County Metro The Tukwila Multimodal Station would be located south of S Longacres Way/S 158th —'Stree and north of the future SW 27th Street/Strander Boulevard right-of-way 4 and bounded to e east and west bytheUnion Pacific n a crfic and BNSF mainline railroad tracks. Access to the station would be provided via S Longacres Way/S 158th Street and SW 27th Street/Strander Boulevard. The multimodal station would function as part of a regional transit system serving vehicular traffic, commuter rail, buses, pedestrian and bicyclists. The Tukwila Multimodal Station is expected to open in late Spring 2001. It would be one of eight stations to be built along the initial 40-mile Tacoma-to-Seattle Sounder commuter rail line. Eventually, the system would be expanded to serve additional communities from Lakewood to the south and Everett to the north. As part of construction of the Tukwila Multimodal Station, a park-and-ride facility would be provided. Initially constructed with approximately 430 stalls, the ultimate buildout would provide parking for 630 vehicles by 2010. Commuter rail users are expected to arrive at the Tukwila Station by the following modes: driving or riding in a private vehicle, riding in a feeder or local bus,or walking or bicycling. When the. Tukwila Station opens in late spring of 2001, Sound Transit would operate a minimum of 2 trains running per day with ridership estimated at approximately 200 a.m. boardings commuter rail, generating 200 vehicular trips. The number of commuter rail trains, passenger boardings and park-and-ride lot parking spaces would gradually increase until full operations are provided. At full operations (2007-2010), the Sounder line would run in each ( direction at half-hour intervals during peak commute periods between 6 a.m. to 9 a.m. and 4 p.m. to 7 p.m. As such, at full operation, the Tukwila Multimodal Station would be served by i approximately 18 train trips per day, 9 trips in the morning and 9 trips in the evening with 6 trips inbound and 3 trips outbound for both morning and evening commuter peak periods. King Country-Metro plans to serve the Tukwila Multimodal Station via Route 140 (formerly known as Route 340) and potentially re-route Route 140 to serve the Boeing Longacres Office Park. The new transit route would continue to serve SW Grady Way but would then head south on Oaksdale Avenue SW, west on SW 16th Street, access the Boeing Frontage Road, head south on Jackson Avenue SW,head west under the underpass on S Longacres Way/S 158th Street and then serve the Tukwila Multimodal Station. For this routing change to occur, the underpass on S Longacres Way/S 158th Street would need to be re-opened. The routing change would occur with the opening of the Tukwila Multimodal Station, potentially late spring of 2001. No other transit routes would serve the station given the limited 2 peak hour commuter rail runs per weekday that would be provided initially. However,when the station becomes fully operational by 2010, King County-Metro would divert more service to Tukwila Multimodal Station, but service times and routes have yet to be determined. Transportation Engineering NorthWest,LLC September 29, 15 Pagege 15 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Site Access and Circulation Access to the existing site is currently provided via 5 existing driveways onto Oakesdale Avenue SW. Vehicular access at existing site driveways are regulated by a center, two-way left-turning lane,which minimizes turning movement impacts into and out of project driveways on roadway operations. A fully-actuated traffic signal is currently located on Oakesdale Avenue SW at its intersection with site driveways leading to the BCAG Headquarters (Building 25-10) to the west, and the Family Center(Building 25-20) to the east. Future vehicular access would be provided onto Oaksdale Avenue SW,Jackson Avenue SW,and SW 27th Street. Driveways locations and off-sets relative to adjacent intersections and driveways would be designed based on standard traffic engineering methods and practices and in accordance with local guidelines as follows: > No driveways would be located within a minimum of 150 feet of an arterial intersection. > Minimum spacing standards of 150 feet between driveways along roadways would be developed such that adequate left.turning storage is provided, traffic flow constraints are reduced, and turning movement conflicts are minimized. 2 w►l$f$atawi > Opposing driveways would be aligned when possible. - 'offset by4150 feet. > Access and egress control at most driveways where moderate volumes are e .e t • . • forded through center, two-way left-turning lanes on public streets.

Sound Transit estimates access mode shares to the station during peak periods as 50 percent bus transfer, 45 percent park-and-ride, and.5 percent via nonmotorized modes. These ridership forecasts prepared by Sound Transit were made prior to the Boeing LOP Master Plan that was completed in 1995, and assumed continued operation of the Longacres Race Track. - • Commuter rail ridership estimates prepared by TENW of the Boeing LOP campus itself is estimated at 400 inbound and 400 outbound passengers per day at the Tukwila Multimodal Station at full buildout. Inbound commuter rail ridership of 100 reverse direction boardings per day prepared by Sound Transit assumed the construction of a convention center and other supporting uses at the station. Given that a convention center and.the Longacres Race Track are no longer anticipated or in use at the site, an estimated net increase in commuter rail ridership of approximately 300 inbound reverse direction boardings per day would result due to Boeing LOP Master Plan over those ridership projections prepared by Sound Transit in 1992. Note: these commuter rail ridership projections do not include any ridership potential of the proposed 20-acre transit-oriented development at the Tukwila Multimodal Station that is being proposed jointly by Sound Transit and the City of Tukwila.

Transportation Demand Management Programs Ridership on public transportation (i.e., transit, commuter rail, etc.) and attractiveness at the employment site trip-end is primarily related to parking management characteristics, transit accessibility and levels of service, and vicinity land uses within walking distance. Secondary issues include total travel time, congestion, and other available modal opportunities. Parking management strategies at the employment site are inherently part of the equation for transportation demand management, such as parking pricing strategies or carpool/vanpool incentives. To achieve non-HOV mode splits identified in this transportation study and to meet the requirements of Washington State's Commute Trip Reduction (CTR)Act of 1990,Boeing would implement a series of traditional transportation demand management (TDM) programs that would be targeted at employees working at the site. Types of specific TDM elements that would _ be considered at Boeing LOP are summarized in Table 6, however, no specific elements have been identified at this time. Boeing currently provides preferential parking for carpools and vanpools, subsidy for transit and other public transportation modes,work schedule options and staggered work shifts, and on-site transportation coordinators and ridematching services to existing employees at Boeing LOP and at many other of their employment sites throughout Renton and the Puget Sound region.

Generally, as vehicular traffic volumes increase, the transportation system becomes more congested, and a commensurate increase in collision experience can occur. However,given existing safety conditions in the site vicinity and planned transportation improvements, it is anticipated that collision experience would remain similar to existing patterns and rates exhibited by existing facilities and not result in adverse impacts to public safety via transportation systems in the immediate site vicinity. Walk trips and access to the adjacent Tukwila Multimodal Station as well as other transit services in the immediate site vicinity could increase the potential for conflicts to occur between walking and bicycling activity and vehicle traffic. As such, general site development guidelines and planning of vehicular and pedestrian access points and related facilities would be developed to minimize as best possible the potential for.conflict zones between motorized and nonmotorized modes. In addition the applicant, to ensure safe nonmotorized movements and access to the Tukwila Multimodal Station area,would construct an appropriate crossing treatment of Jackson Avenue SW._ Status: not complete.

The Addendum will update the development proposal to include an additional 500,000 square feet of building area—for a revised total of 3 million gross square feet in building area(initial proposal was for 2.5 million gross square feet). The additional square footage would be accommodated through increased building height within the range of heights previously analyzed, and would not increase building footprint areas. The SEPA Rules allow the use of an Addendum in order to provide additional information or analysis that does not substantially change the analysis of significant impacts and alternatives in the existing environmental documents (WAC 197-11-706). The applicant has provided additional analysis of the updated proposal in order to confirm all potential impacts have been adequately analyzed and mitigated in the existing documents(e.g., 1994 LOP EIS and Mitigation Document). The information submitted by the applicant is being routed in order to obtain comments regarding this analysis from City staff. Please note that on a project specific basis, future LOP development will receive separate project level Environmental(SEPA) Review under which the opportunity to place additional mitigation measures will be made available. The applicant has also proposed a Development Agreement in order to establish applicable development regulations, including a vesting framework and other restrictions, for the LOP development project. The Development Agreement is based on the LOP EIS, as well as modifications to the LOP development proposal as established by the Addenda process.

RECITALS 1. Broadacres is the owner of part of the real property depicted in Exhibit "A" attached hereto (the "Property"). 2. The Washington Horse Breeders Association desires to rezone and to construct barns and other improvements on part of the Property. 3. The Environmental Review Committee of the City of Renton has required as an environmental condition that Broadacres reserve for twenty-five (25) years that portion of the property described in Exhibit "B" attached hereto (the "Restricted Property"), which constitutes the proposed site of the westerly extension of S.W., 27th Street. 4. Broadacres will accomplish this reservation by agreeing not to construct for 414 twenty-five (25) years any permanent structures on that portion of the property described in Exhibit "B" or within the setbacks established by the adjacent zoning r„( designations. C. 5. Broadacres has agreed to enter into such restrictive covenants on the condition itr that the City agree, during the term of this agreement, that such covenants do not in any way preclude Broadacre's right to receive full value for any of the Restricted Property taken in any condemnation proceedings. 6. Broadacres does not dispute the need of the major east-west arterial, S.W. 27th Street, nor its intended location, provided that Broadacres reserves all rights in any subsequent condemnation action. NOW, THEREFORE, Broadacres and the City agree as follows: 1. The City of Renton cannot deny access to or between either of the parking lots. Access shall be designed and controlled by City standards in effect at the time of street construction. 2. If either of the two parcels abutting the right-of-way depicted in Exhibit "A"is rezoned and developed in any use incompatible with recreational horse racing, Broadacres will dedicate and construct upon some portion or all of the property described in Exhibit "B", a local access road (not a major arterial) according to City of Renton street standards for local access roads. . ;;.

Elizabeth Warman, The Boeing Company Laura Whitaker, Perkins Coie : - 1055 South Grady Way-Renton,Washington 98055 CITY OF RENTON Planning/Building/Public Works MEMORANDUM DATE: October 25, 2000 TO: Neil Watts, Director, Development Services Division FROM: Lesley Nishihira,Associate Planner, Development/Planning SUBJECT: Review Process for Boeing Longacres Development Agreement File No. LUA-00-130 The purpose of this memo is to outline the review process and analyze the potential impacts of the proposed update to the Boeing Longacres Office Park(LOP) Development Proposal, as well as establish the review process for the proposed LOP Development Agreement. Modifications to Initial Development Proposal—The Boeing Company is proposing modifications to the proposed office park development,which was reviewed under the 1994 Longacres Office Park Environmental Impact Statement(LOP EIS). The LOP EIS described the environmental impacts of a 164-acre, 2.5 million square foot master planned development, including offices, an employee center, related support and utility facilities, and open spaces amenities. The current proposal is to increase the total gross square footage of building area by 500,000 square feet. This would be accomplished by increasing the height of the proposed buildings. For reasons discussed in detail in the analysis portion of this memo, the proposed increase in building area has been determined to not substantially change the analysis of significant impacts and alternatives contained within the existing 1994 LOP EIS. Therefore, an addendum will be prepared in order to update the proposal for which the previous EIS was conducted. The addenda process will be conducted pursuant to WAC 197-11-625 (Addenda Procedures)and WAC 197-11-706 (Addendum Definition), which establish that the addendum must clearly identify the proposal and the environmental'document that it is adding to. The addendum is not required to be routed for notification and is not subject to comment or appeal periods. The updated LOP proposal will be routed internally for departmental comments. The addendum will subsequently be presented to the Environmental Review Committee for adoption after staff comments have been considered. Development Agreement— In addition to the proposed modifications discussed above, the applicant is requesting the approval of a Development Agreement in order to establish applicable development regulations, including a vesting framework and other restrictions,for the Boeing LOP development project. The Development Agreement is based on the 1994 LOP EIS, as well as modifications to the LOP development proposal as established by the addenda process. The LOP EIS contains detailed environmental analysis for the LOP proposal, including the phases of the office park development. The Development Agreement is adequately covered under the umbrella of the analysis contained within the EIS, as well as within the forthcoming EIS addendum. As established by RCW 36.70B.190-200,the Development Agreement must be approved by the City through ordinance or resolution after a public hearing is held. The Development Agreement must then be recorded by the County once the ordinance or resolution is in effect. The agenda bill process and a public hearing before the City Council for the Development Agreement will be conducted after the completion of the addendum to the 1994 LOP EIS. Please Updated Boeing LOP Proposal/uevelopment Agreement October 25,2000 Review Process&Analysis of Impacts File No. LUA-00-130 Page 2 of 5 note that on a project specific basis, future LOP development will receive additional separate project level environmental review under which the opportunity to place additional mitigation measures will be made available. Analysis of Environmental Impacts—The proposed increase in building area has been determined to not substantially change the analysis of significant impacts for the preferred option as contained within existing environmental documents for the LOP development project. The adopted LOP EIS and Mitigation Document included analysis of existing conditions, potential impacts of the proposed action, required mitigation measures, and optional mitigation measures. The impacts of the proposed building square footage increase to the preferred option, or the "proposed action," is analyzed for each element described within the 1994 LOP EIS as follows: • Earth: The potential impacts from the LOP development to earth resources include exposed soils during construction, on-site drainage, structures in 100-year floodplain, and seismic hazards—all of which were found to have no significant unavoidable adverse impacts that could not be mitigated. The proposed increase in building area would be accommodated by an increase in building height and would not increase the building footprint area. Therefore, the existing environmental documents adequately address and mitigate the proposal's impacts to earth resources. • Air Quality: The LOP EIS analyzed the development project's potential for carbon monoxide, ozone precursors, and fugitive dust emissions during construction and found there to be no significant unavoidable adverse impacts that could not be mitigated. The updated proposal would not alter the potential impacts from construction to air quality and is adequately covered and mitigated by the existing environmental documents. • Groundwater: Impacts to groundwater analyzed in the LOP EIS include: possible temporary reduction in recharge, temporary lowing of the water table, and introduction of contaminants during construction; potential increase in sedimentation in wetlands or streams during construction; possible changes in recharge during operation due to increased impervious areas; possible contamination of groundwater due to infiltration of contaminated storm water; and, potential contamination of groundwater due to accidental spills or leaks of hazardous materials. Unavoidable adverse impacts were found not to occur since anticipated short-term and long-term groundwater impacts could be mitigated. The proposed square footage increase would not create additional impacts to groundwater than those analyzed in the existing environmental documents. • Surface water quantity/quality:The LOP EIS examined significant(direct, indirect, and cumulative) impacts to surface water, including: the filling of approximately 59 acres to bring elevations above floodplain elevations; increased runoff following storm events due to increased impervious surfaces; the potential for increased sediments, nutrient loads, and contaminants reaching Springbrook Creek; and, the potential for warmer stormwater reaching Springbrook Creek. Some loss of infiltration to groundwater and a percentage of nutrients and metals entering receiving surface water were found to be unavoidable adverse impacts from the development project. Existing codes and required mitigation measures were adopted as part of the LOP EIS in order to address these impacts. Due to the evolving regulation of stormwater management in response to Endangered Species Act considerations, additional stormwater analysis for the updated LOP development was provided by the applicant. The updated Drainage Report prepared by Sverdrup Civil, Inc., dated September 2000, demonstrates that the construction of the project will be in compliance with current City surface water regulations. Measures proposed by the applicant in order to avoid or reduce the potential impacts to surface water include: surface water collection systems that incorporate deep sump catch basins that will trap sediment; storm drainage catch basin that include inverted elbows to reduce passage of oils and other floating debris; storm drainage vaults sized to accommodate future coalescing plate oil/water Updated Boeing LOP Proposal/Development Agreement October 25,2000 Review Process&Analysis of Impacts File No. LUA-00-130 Page 3 of 5 separators in those areas subject to high vehicular use; combination wetpond/detention ponds that will reduce peak flows and improve water quality; and, landscape plant materials that will reduce flow velocities, prevent erosion, stabilize slopes, and provide water quality benefits. The updated proposal for additional building area is not anticipated to alter the potential impacts from the project to surface water and appears to be adequately covered and mitigated by existing environmental documents. However, the Surface Water analysis and proposed mitigation measures presented by the applicant will be reviewed by the appropriate City departments in order to verify the proposed increase in building area through additional building height would not alter the conclusions of the existing environmental documents. Although the amount of required on-site parking may increase due to the additional building area, the analysis of the project's compliance with the parking regulations will be analyzed on a project specific basis. If additional parking areas are necessary, the creation of additional impervious area must be consistent with the LOP EIS and addendum. The applicant may be required to propose alternative means for satisfying the parking regulations if additional impervious areas are found to be outside of the impacts analyzed within the existing environmental documents. • Natural Environment:The analysis of potential impacts from the LOP development to the natural environment included land clearing and tree cutting, landscaping installation and maintenance, wetland mitigation, additional landscape requirements for wildlife, and avoidance of destroying active nests—all of which were found to have no permanent unavoidable adverse impacts after required mitigation. In addition, unavoidable adverse impacts were found not to occur to fish resources (specifically Springbrook Creek)since anticipated impacts could be mitigated to provide storm water management systems and to control pollutants. The updated proposal would not increase potential impacts to the natural environment, nor require changes to the mitigating measures identified in the adopted environmental documents. • Environmental Health: The LOP development's impacts from noise and environmental materials were addressed in the EIS, including the potential for noise from construction equipment and the potential for spills and leaks during project construction. Other than potential accidents during construction, no unavoidable adverse impacts were found to exist to environmental health. Potential impacts resulting from the proposed increase to building area are adequately reviewed in the existing environmental documents. • Land use: Potential impacts to land use from the LOP development project addressed in the EIS include potential disturbances to surrounding land uses during construction, as well as potential inconsistencies with Renton policies encouraging parking structures for office developments. Mitigating measures include coordinating schedule of construction activities and developing programs to notify and address concerns from neighboring land uses. The updated proposal would not alter the potential impacts from the development to surrounding land use and is adequately covered and mitigated by the existing environmental documents. • Socioeconomics: Based on the existing environmental documents,there were no impacts from the LOP development to socioeconomics. The proposed revision to the amount of gross building area would not alter the conclusions of the LOP EIS or Mitigation Document. • Visual Resources: The LOP EIS analyzed potential impacts from the project such as potential light and glare to motorist on 1-405 and surrounding residential areas. No unavoidable adverse impacts were found to exist provided the project complies with adopted mitigation measures. These measure include performance of a light and glare analysis and provision of visual screening, if necessary. The proposed increase in building area would be ( accommodated by building heights remaining within the height range analyzed in the LOP EIS (exact heights have yet to be determined by the applicant). Therefore, potential impacts Updated Boeing LOP Proposal/Development Agreement October 25,2000 Review Process&Analysis of Impacts File No. LUA-00-130 Page 4 of 5 from the proposed increase in building area to visual resources are adequately addressed by existing environmental documents. • Historic and cultural resources: The potential for detecting or damaging cultural sites by moving soil during site preparation/construction was identified as a potential impact in the LOP EIS. Mitigation measures intended to prevent impacts to such resources were adopted as part of the Mitigation Document. The increase in building area proposed would not require additional analysis, nor mitigation for historic or cultural resources beyond that contained within existing environmental documents. • Transportation:The LOP EIS took into account the development's potential impact to increased traffic volumes in the City of Renton and the City of Tukwilla, as well as to increased ridership on transit systems. Unavoidable adverse impacts were found not to occur since anticipated short-term and long-term transportation impacts could be mitigated through payment of required mitigation fees for both jurisdictions, as well as specified improvements within the City of Renton. With the adoption of the Mitigation Document for the development, the applicant agreed to provide for roadway and intersection improvements (e.g., 158th, Longacres Drive), provide on-site access routes, provide a service system that encourages utilization of TDM programs, and participate in the extension of Oakesdale Avenue for necessary circulation and emergency access to the site. Movement and circulation patterns were also analyzed and determined to require arterial street standard sidewalks with roadway construction (South 158th Street, Longacres Drive, Oakesdale Avenue SW, SW 16th Street, and SW 27th Street). The proposed parking was also determined to be appropriate provided a medium level TDM program would result in less demand for parking. Future parking needs will need to be analyzed on a project specific basis. The EIS projected the daily vehicle trips to be generated by the LOP development in the year 2010 to be approximately 28,900 trips under a medium transportation demand management (TDM)level with a 3 plus HOV rate. The impact from these daily trips on the Renton Valley and the City were anticipated in the development of the transportation system improvement plans in the City of Renton Draft Final Transportation Element and were included assumptions in the City's Comprehensive Plan. An updated Transportation Study prepared by Transportation Engineering NorthWest, dated September 29, 2000, was provided by the applicant in order to analyze potential impacts from the updated proposal. The study evaluated two separate trip generation scenarios for the 3.0 million square foot total buildout. These evaluations included: 1)the use of methods and assumptions consistent with those documented in chapter 14 of the 1994 LOP DEIS accounting for mode split adjustments given the adjacent Tukwilla commuter rail station and multimodal center; and, 2)the use of current transportation engineering methods and assumptions given the adjacent Tukwilla commuter rail station and multimodal center. Under either scenario,the study concludes there would be a net decrease in vehicle trip generation over vested buildout levels when evaluating the updated buildout of 3.0 million square feet of office use. Furthermore, impacts to ridership on commuter rail services are estimated to be in a reverse direction and would not adversely impacts excess passenger capacity of commuter rail operations. The applicant has proposed to install appropriate crossing treatments to Jackson Avenue SW in order to minimize pedestrian/vehicle conflicts. In addition, TDM programs and Commute Trip Reductions requirements will be implemented for the project. Based on the information provided by the applicant,the existing environmental documents appear to adequately address the potential increase to transportation impacts from the updated proposal. However, the submitted Transportation Study will be thoroughly reviewed by City staff in order to verify conclusions are accurate. Furthermore, through the approval X Updated Boeing LOP Proposal/Development Agreement October 25,2000 Review Process&Analysis of Impacts File No. LUA-00-130 Page 5 of 5 process for the Development Agreement, City staff will recommend the amendment of the Mitigation Document to include necessary improvements to SW 27th Street in order to address increased transportation impacts to that roadway. • Natural Resources and utilities: Impacts to natural resources and utilities found to be associated with the LOP development include increased demand for water, sewer, solid waste disposal, electric and natural gas, as well as possible interruption in service to other uses during construction. Unavoidable adverse impacts, such as cumulative impacts to the water supply and to the sewer service, would be mitigated by measures contained within the adopted Mitigation Document. The updated proposal would not increase potential impacts to the natural resources and utilities, nor require changes to the mitigating measures identified in the adopted environmental documents. • Public Services: The LOP EIS analyzed potential impacts to fire protection and emergency medical services from the proposed development. Unavoidable adverse impacts were found to be mitigated by required payment of the Fire Mitigation Fee. The proposed increase in building area would not substantially affect the existing analysis contained with the existing environmental documents. Future project specific proposals will be required to undergo individual SEPA and Site Plan review and will, therefore, have the appropriate mitigation fees imposed on an individual basis. If you concur with the intended review process for the LOP addendum and LOP Development Agreement, as well as with the analysis of potential impacts from the updated proposal, please sign and date below. / ia t t Neil Watts, Director Date Development Services Division cc: File No. LUA-00-130 Jennifer Henning, Principal Planner Gene Warden, Boeing (applicant) Laura Whitaker, Perkins Coie (contact) <`` '' OF 'E TO ,: > < ?<s'>< >'<:> '>> :{:< i<< < ` : >'> <' : :' <>aii ELO.PM. ::;::: ..V . .:.:. .N 11= DIVI f G inzaingusilitim ::::::>::::>:>::::::> ...........L >: .: ■■r `:` y��":'iihfi:� :::: ::' ::;:;::_. �:..':::::: oi. :::::' ::::��:: :^:' ` : :'<;.:: '<':: :: .. >::..•.'.

It was then estimated that the office park would be developed over a ten to fifteen year period according to Boeing's corporate needs, and would include approximately 10,000 employees at full build out. In 1995, the City issued a Mitigation Document for the office park setting forth-required mitigation for project development. Two buildings have been constructed since 1995 -- BCAG Headquarters (1997) and Renton Family Care Center (1998). In 1999, the Surface Water Management Project ("SWMP") was constructed. SWMP is a stormwater system for the office park consisting of a combination of wetponds, detention ponds and created wetlands sized to accommodate the master plan at full build-out. In preparation for site development, Boeing now proposes to enter into a Development Agreement with the City pursuant to the requirements of RCW 36.70B.170 through .210. The Agreement describes the basic parameters of proposed office park development and is based on the 1994 EIS and additional environmental analysis of certain aspects of the project (i.e., impacts on traffic and the site's stormwater system). The updated environmental analysis discusses any additional impacts caused by increasing the height of certain buildings to achieve a 500,000 square foot increase in total gross square footage. The Development Agreement will also establish applicable development regulations, including development standards set forth in the Renton Code, a vesting framework, and other restrictions. Boeing desires to obtain approval of the Development Agreement by December 2000. The Master Plan for Longacres Office Park ("Master Plan") includes the construction of approximately 3 million square feet of office or light industrial space, related support and utility facilities, and open space amenities over a period of up to 15 years. Approximately 15 separate buildings would occupy the site upon completion. Of the 158 acres comprising the LOP site, the Master Plan proposes that approximately 79 acres will be impervious surface (i.e., buildings, parking areas or parking structures, and roadways), approximately 11 acres will be dedicated to a stormwater detention system, and approximately 68 acres will be devoted to landscaping and open space. The Master Plan is attached to the Development Agreement as Attachment 2.

SUPPLEMENTAL SHEETS FOR NONPROJECT ACTIONS (These sheets should only be used for actions involving decisions on policies, plans and programs. You do not need to fill out these sheets for project actions.) Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions,be aware of the extent the proposal, or the types of activities likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. [03003-0 1 61/Envir Cklt.DOC] -20- 9/29/00 Environmental Checklist 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The proposal vests development regulations applicable to the LOP site. It does not significantly alter the project parameters described and analyzed by the LOP EIS or by other environmental analysis (including analysis of the LOP stormwater management system) performed with respect to site development. Due to evolving regulation of stormwater management in response to Endangered Species Act considerations, additional stormwater analysis of proposed LOP development has been performed and is attached as Exhibit B. This analysis demonstrates that construction of the master plan will comply with the City of Renton's current surface water management regulations. Proposed measures to avoid or reduce such increases are: • Surface water collection systems that incorporate deep sump catch basins that will trap sediment. • Storm drainage catch basins that include inverted elbows to reduce passage of oils and other floating debris. • Storm drainage vaults sized to accommodate future coalescing plate oil/water separators in those areas subject to high vehicular use. • Combination wetpond/detention ponds that will reduce peak flows and improve water quality. • Landscape plant materials that will reduce flow velocities, prevent erosion, stabilize slopes and provide water quality benefits. 2. How would the proposal be likely to affect plants, animals, fish, or marine life? The proposal vests development regulations applicable to the LOP site. It does not significantly alter the project parameters described and analyzed by the LOP EIS or by other environmental analysis (including analysis of the LOP stormwater management system) performed with respect to site development. As demonstrated by this existing analysis, construction of the master plan will comply with the City of Renton's current surface water management [03003-0161/Envir Cklt.DOC] -21- 9/29/00 Environmental Checklist regulations, which are designed to protect both the project and off-site environments. Proposed measures to protect or conserve plants, animals, fish, or marine life are: the same measures that will reduce impacts to off-site surface waters, as described in part D(1), above. 3. How would the proposal be likely to deplete energy or natural resources? The proposal vests development regulations applicable to the LOP site. It does not significantly alter the project parameters described and analyzed by the LOP EIS or by other environmental analysis performed with respect to site development. As demonstrated by the Mitigation Document, impacts of the LOP project on energy and natural resources are not significant, meet all applicable regulations, and/or will be mitigated at the time individual projects are developed on the LOP site. Proposed measures to protect or conserve energy and natural resources are: Not applicable at this time. 4. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, flood plains, or prime farmlands? The proposal vests development regulations applicable to the LOP site. It does not significantly alter the project parameters described and analyzed by the LOP EIS or by other environmental analysis performed with respect to site development. As demonstrated by existing environmental analysis with respect to the LOP site (e.g., LOP EIS, section 404 permits issued by the Army Corps for construction of the LOP Stormwater Management System, and the supplemental stormwater system analysis attached to this checklist as Exhibit B), the LOP project meets all applicable water quality regulations and is not anticipated to adversely impact endangered species or other wildlife. Proposed measures to protect such resources or to avoid or reduce impacts are: Not applicable at this time [03003-0161/Envir Cklt.DOC] -22- 9/29/00 Environmental Checklist 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? The proposal vests development regulations applicable to the LOP site. It does not significantly alter the project parameters described and analyzed by the LOP EIS or by other environmental analysis performed with respect to site development. Proposed measures to avoid or reduce shoreline and land use impacts are: Not applicable at this time. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? Impacts to ridership on commuter rail services are estimated at 400 one-way boardings during the p.m. peak hour in the reverse commute direction, resulting in a net increase of 300 one-way daily boardings over current ridership estimates. This demand for ridership, however, would be in the reverse commute direction and would not adversely impact excess passenger capacity of commuter rail operations. For additional information regarding the transportation impacts of this nonproject proposal, see Exhibit C. Proposed measures to reduce or respond to such demand(s) are: To minimize impacts of this ridership demand, the applicant would install an appropriate crossing treatment on Jackson Avenue SW to minimize conflicts between vehicle traffic and employee walk access, and to provide a safe and attractive route for commuter rail patrons between the Tukwila Multimodal Station and Boeing LOP. The project applicant would also implement traditional transportation demand management (TDM) programs through a series of parking management strategies, subsidy elements and incentives, site amenities, work schedule and other special programs and operations to reduce project impacts during peak commute periods and meet Commute Trip Reduction (CTR) requirements. [03003-01 61/Envir Cklt.DOC] -23- 9/29/00 Environmental Checklist 7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment.

RECITALS WHEREAS, the Boeing Company has proposed to develop an office park ("Office Park") at the site of the former Longacres Race Track; and WHEREAS, several alternatives for the Office Park have been evaluated by the City of Renton as lead agency in accordance with the requirements of the State Environmental Policy Act ("SEPA"); and WHEREAS, significant environmental impacts of the Office Park were identified in an environmental impact statement for the Office Park issued by the City of Renton in August of 1994 ("Office Park EIS"), including impacts to the Tukwila transportation system; and WHEREAS, measures mitigating the adverse environmental impacts caused by Boeing's preferred alternative for the Office Park ("Alternative 1") are set forth in a Mitigation Document issued by the City of Rentort'in May, 1995 ("Renton Mitigation Document"); and WHEREAS, the Renton Mitigation Document states that the terms and conditions for the assessment and collection of mitigation fees for traffic impacts to the Tukwila transportation system shall be established in a separate agreement between Boeing and Tukwila; and WHEREAS, additional evaluation of adverse impacts to the Tukwila transportation system will be required during the environmental review for each specific development phase.of Alternative 1; and WHEREAS, significant adverse impacts to the Tukwila transportation system caused by a specific development phase of Alternative 1 and not previously identified by the Office Park EIS may be mitigated as a condition of approval of that specific development phase; 12/06/2000 16:50 FAX 41 003/009 • Longacres Park Mitigation Agreement 12/6/95 Page 2 AGREEMENT NOW,THEREFORE, in consideration of this and other good and valuable consideration,the sufficiency of which is hereby acknowledged,the parties agree as follows: 1. EIS Analysis Mitigation measures set forth in this Agreement("Tukwila Mitigation Fees") are sufficient to mitigate impacts to the Tukwila transportation system of Alternative 1 as analyzed in the Office Park EIS and summarized in the Renton Mitigation Document. 2. Basis of Mitigation/Mitigation Amount The Tukwila Mitigation Fees have been calculated according to the methodology set forth in the Draft Transportation Element in the City of Tukwila Draft Comprehensive Plan (1993). Using this methodology, the vehicle trips, distribution of trips, and corresponding mitigation payments generated by Alternative 1,were calculated as follows: Intersection Number of Cost per Mitigation Location Veil_ Trips Vehicle Trip Cost • 1) Southcenter Pkwy/ Strander 156 $ 140 • $ 21,840 2) Andover Pk E/Strander 234 $ 135 $ 31,590 3) Andover Pk W/Strander 117 $ 377 $ 44,109 4) S 180/SR 1 S 1 117 $475 $ 55,575 5) Andover Pk E/I3aker 0 .. $ 377 $ 0 6) Andover Pk W/Minkler 117 $ 392 $ 45,864 7) Southcenter Pkwy/S 168th 117 $ 278 $ 32,526 8) W Valley/Strander 350 $ 283 $ .99,050 9) Interurban Bridge & Interchange 623 $1,122 $ 699,006 TOTAL TRIPS/FEES: 1,831 S1,029,560 3. Payment Because the construction of Alternative 1 is planned over a 10-15 year permd, Tukwila has established two optional methods for payment of the Tukwila Mitigation Fees. Boeing shall exercise, at its sole discretion, one of these options for payment of the Tukwila Mitigation Fees. Option 1 recognizes the benefits to Tukwila of receiving the total Tukwila Mitigation Fee in a single payment. In addition to the time value of money, a single payment would provide Tukwila with a substantial amount of money at once, thereby (a) avoiding the need to accumulate funds in smaller increments over a long period of time before meaningful construction could begin and (b) facilitating the acquisition of matching funds. Payment under Option 1 is nonrefundable and is not subject to future rate increases. Boeing, as part of its decision to exercise Option 1, may choose to negotiate with Tukwila to establish how, where, and when early payment 12/06/2000 16:50 FAX Z 004/009 Longacres Park Mitigation Agreement 12/6/95 Page 3 moneys will be expended. Option 2 provides for incremental payments of the Tukwila Mitigation Fees to mitigate the impacts caused by specific phases of Alternative 1. The two options are as follows: 3.1 Option 1 -December 31, 1995 Payment The total Tukwila Mitigation Fee will be discounted from $1,029,560 to $830,000 if the total fee is paid before December 31, 1995. If Boeing chooses to construct an alternative for the Longacres Park office development other than Alternative 1, fees paid under Option 1 will be credited against any fees assessed to mitigate the transportation impact of that alternative. 3.2 Option 2 -Incremental Payments Tukwila Mitigation Fees will be assessed against each phase of Alternative 1 in accordance with the specific impact resulting from that phase; provided, that the total Tukwila Mitigation Fee shall not exceed$1,029,560,unless, additional fees are imposed pursuant to Section 5 as set forth below. 4. Status of Transportation Projects The parties acknowledge that several projects referenced in Section 2 of this Agreement are currently being designed or constructed and in some cases have already been completed. The current status of such projects shall in no way impact Tukwila's authority to collect mitigation fees under this Agreement. 5. South 158th Street-Limitations,,Monitoring, Review The AM and PM peak hour trips for South 158th Street which are attributable to and that may be utilized by the Office Park development shall be limited to 390, which is the"existing condition" for South 158th Street as set forth in the Draft Transportation Element of Tukwila's Draft Comprehensive Plan (1993). Notwithstanding the foregoing, capacity on South 158th Street for AM and PM peak hour trips exceeding 390 that is created as a result of South 158th Street improvements may be utilized by, and only by, the entity financing those improvements. Improvements that may be necessary to increase the number of PM peak hour trips on South 158th Street to accommodate additional traffic generated by Alternative 1 shall be identified through the environmental review process for each phase of development. Tukwila shall periodically monitor AM and PM peak hour traffic volumes on South 158th Street to ensure that limitations are not exceeded by any specifically identifiable entity using the right-of-way. Monitoring will occur at least anriZally and more frequently if volumes approach the maximum peak hour trips. Monitoring methodology shall be consistent with traffic engineering practices and shall be mutually agreed upon by both parties prior to initiating any monitoring effort. In the event that peak hour limitations are exceeded, Tukwila reserves the right to review the need for additional improvements and to assess additional impact mitigation fees against the entity creating the unmitigated traffic impacts and any such additional impact fees shall be in addition to and not withstanding the total fees provided for in Section 3.2 above. 12/06/2000 16:50 FAX 12005/009 Loneacres Park Mitigation Agreement 12/6/95 Page 4 6. Assignment This Agreement shall be binding upon and inure to the benefit of the successors and assigns of both parties hereto. 7. Severability In the event that a court of competent jurisdiction determines that any phrase, section, subsection or clause in this Agreement is invalid, all remaining phrases, sections, subsections, or clauses shall remain in full force and effect.

The Mitigation Document acknowledged the impacts to the City of Tukwila transportation system and stated that the terms for payment were to be established through separate aareetnent between the City of Tukwila and Boeing. ISSUE ANALYSIS: • Boeing staff and Tukwila staff began working on the terms of the"separate agreement" this past summer and Were able to obtain a tentative agreement on agreement language this past October (see attached agreement; version 12/6/95). The agreement was then presented for review by the City Attorney and recommended changes were incorporated and forwarded to Boeing for final review. The agreement, with the changes by the Attorney's Office, was presented to the Transportation Committee on December I lth. Boeing staff contacted my office on December 13th to inform us that their legal staff has accepted the agreement as modified by our City Attorney. The City of Tukwila's authority to impose mitigation for the proposed Boeing Longacres Office Park is limited by the findings and conclusions stated in the Mitigation Document released by the City of Renton this past May. The exception to this limitation would be the extent to which Boeing deviates from their development proposal upon which the. environmental process was based. The attached agreement includes provisions to • conduct further review in the case of significant modifications to their development proposal. RECOMMENDA TXON: Since the agreement has been to the Transportation Committee for review, I recommend we now present it to the City Council at the Regular Meeting on December 18th and request authorization for the Mayor to sign and execute it . This will allow us to "wrap up" the process and approach the new year with the agreement in hand. Please advise as to how you wish to proceed. 12/06/2000 16:51 FAX . . ___ _____ _____ Z008/009 .

Sincerely ene Warden Project Manager (206) 544-7448 t�^ EXHIBIT A Z) DEVELOPMENT AGREEMENT BETWEEN THE BOEING COMPANY AND THE CITY OF RENTON FOR FUTURE DEVELOPMENT OF LONGACRES OFFICE PARK I. PREAMBLE This DEVELOPMENT AGREEMENT ("Agreement") between THE BOEING COMPANY ("Boeing"), a Delaware corporation, and the CITY OF RENTON ("City"), a municipal corporation of the State of Washington, is entered into pursuant to the authority of RCW 36.70B.170 through .210, under which a local government may enter into a development agreement with an entity having ownership or control of real property within its jurisdiction. II. RECITALS A. Boeing is the owner of certain real property, known as the Longacres Office Park ("LOP"), located in the City of Renton, King County, Washington, and more particularly described in Attachment 1, attached hereto and by this reference incorporated herein. B. LOP consists of approximately 158 acres located at the southeast intersection of Interstate 405 and the Burlington Northern Railroad tracks in the City of Renton. Boeing's Customer Service Training Center ("CSTC") occupies an adjacent approximately 48-acre site to the north and east of LOP. LOP is located entirely within the Commercial Office ("CO") zoning district and is designated Employment Center-Valley by the City's Comprehensive Plan. C. The master plan for LOP ("Master Plan") includes the construction of approximately 3 million square feet of office or light industrial space, related support and utility facilities, and open space amenities over a period of up to 15 years. Approximately 15 separate buildings would occupy the site upon completion. Of the 158 acres comprising the LOP site, the Master Plan proposes that approximately 79 acres will be impervious surface (i.e., buildings, parking areas or parking structures, and roadways), approximately 11 acres will be dedicated to a stormwater detention system, and approximately 68 acres will be devoted to landscaping and open space. The Master Plan is attached to this Agreement as Attachment 2 and incorporated herein by reference. [03003-0150/Development Agreement.doc] 9/29/00 - D. Environmental analysis of development of 2.5 million sq. ft. under the Master Plan of the State Environmental Policy Act ("SEPA") was conducted by the City to the requirements. A Draft Environmental Impact Statement ("DEIS") for the Master Plan was issued in August, 1994; the Final Environmental Impact Statement ("FEIS") was issued in March, 1995. A SEPA Mitigation Document ("Mitigation Document") was issued by the City in May, 1995. E. In 1997, Boeing developed the Boeing Commercial Airplane Group ("BCAG") headquarters office building, consisting of approximately 300,000 square feet, as Phase I of LOP. The location and extent of Phase I development is depicted on Attachment 2. F. In 1998, Boeing developed the Boeing Family Care Center ("FCC"), consisting of approximately 22,000 square feet to provide day care services for 200 children as Phase II of LOP. The location and extent of Phase II development is depicted on Attachment 2. G. In 1999, Boeing developed a Surface Water Management Program ("SWMP"), consisting of grading to create stormwater ponds, an irrigation, aeration, and recirculation system, and enhanced wetlands designed to accommodate full build- - out of LOP and associated CSTC site. The location and extent of Phase III 1 development is depicted on Attachment 2. H. As part of the SWMP project, certain critical environmental areas on the Longacres site were identified. These areas include certain enhanced wetlands, the South Marsh, and a wildlife corridor to be generally located between SWMP and the Marsh. On July 6, 1999, Boeing recorded a Declaration of Restrictive Covenants prohibiting development or alteration of the 10.92-acre South Marsh. Site wetlands (including South Marsh) and the area within which a wildlife corridor area will be located are depicted on Attachment 2. I. Phase IV of the Longacres Office Park will consist of the development of approximately 2.7 million square feet of office or light industrial space, with support and utility facilities, on that portion of LOP not developed under Phases I, II, and III or reserved for environmental mitigation purposes pursuant to development conditions. The Phase IV development will be constructed in multiple, campus-style buildings, with parking, roadways, and pedestrian walkways. The Phase IV development envelopes is depicted on Attachment 2. J. Boeing and the City agree that Phase IV should be regulated and mitigated in order to provide certainty and efficiency with respect to the City's review [03003-0150/Development Agreement.doc] -2- 9/29/00 and approval process for that development. Accordingly, Boeing and the City agree as follows: III. AGREEMENT 1. Vesting and Term of Agreement. The City's development regulations in effect and applicable to project applications as of the date that the completed application for this Agreement was submitted ( ) shall govern the development of Phase IV of LOP for all Phase IV development applications submitted to the City within 15 years from the date of this Agreement. Notwithstanding the foregoing, the City reserves the authority under RCW 36.70B.170(4) to impose new or different regulations to the extent required by a serious threat to public health and safety, as determined by the Renton City Council after notice and an opportunity to be heard has been provided to Boeing. 2. Development Regulations. For purposes of this Agreement, "development regulations" means (a) zoning, land division, and development standards, (b) environmental rules and policies, including (but not limited to) SEPA, (c) Comprehensive Plan policies, (d)policies, regulations, standards, and methods applicable to the development of land that are incorporated by reference in the Renton Municipal Code, (e) surface water management regulations, and (f) other City ordinances governing the development of land. Applicable development regulations are attached to this Agreement as Attachment 3 and incorporated herein by reference. 3. Mitigation Document. This Agreement amends the Mitigation Document as follows: (a) Section 1, General Information, second paragraph is amended to read: As indicated in the EIS, numerous state and local regulations will govern development of Longacres Office Park and application of those regulations will also serve to mitigate certain significant adverse environmental impacts. Regulations applicable to specific development actions will be as defined in the Development Agreement between Boeing and the City dated ("Development Agreement"). (b) To the extent that Section 2,Mitigation Plan, references or incorporates development regulations, they shall be as defined by the Development Agreement. 4. Site Plan Review and Minor Modifications. Phase IV development permit applications shall be subject to the City land use review process under the [03003-0150/Development Agreement.doc] -3- 9/29/00 development regulations applicable to such review and approval as of the date of this Agreement. The final design of the buildings and other improvements, precise location of building footprints, land division creating building sites for individual structures, location of utilities, determination of access points, and other land use issues related to authorization of individual issues will be determined during that process and are part of this Agreement. 5.

ORDINANCE NO. 4 8 3 5 (4) The impact due to floodway encroachment shall be analyzed using future land use condition flows. (5) If RMC 4-3-050.I.4.a. is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section. b. Residential Construction in Floodways: Construction or reconstruction of residential structures is prohibited within designated floodways, except for: (1) repairs, reconstruction, or improvements to a structure which do not increase the ground floor area; and (2) repairs, reconstruction or improvements to a structure, the cost of which does not exceed fifty percent (50%) of the market value of the structure either, a) before the repair, reconstruction, or repair is started, or b) if the structure has been damaged, and is being restored, before the damage occurred. Work done on structures to comply with existing health, sanitary, or safety codes or to structures identified as historic places shall not be included in the fifty percent (50%). 5. Compensatory Storage: a. Compensatory Storage Required: Development proposals and other alterations shall not reduce the effective base flood storage volume of the floodplain. If grading or other activity will reduce the effective storage volume, compensatory storage shall be created on the site or off the site if legal arrangements can be made to assure that the effective compensatory storage volume will be preserved over time. Compensatory storage shall be configured so as not to trap or strand salmonids after flood waters recede and may be configured to provide salmonid habitat or high flow refuge whenever suitable site conditions exist and the configuration does not adversely affect bank stability or existing habitat. b. Additional Requirements - Springbrook Creek: The higher of the City hydrologic and hydraulic model results for the 100-year future land use conveyance and storage events shall be used by the City to determine the volume of compensatory storage required for filling within the 100-year flood zone of Springbrook Creek. (1) An exception to this requirement shall apply where the Federal Emergency Management Agency (FEMA) defined 100-year flood zone is lower than the City model results for the 100-year future land use conveyance event. (2) Under the exception, the lower FEMA floodplain elevation shall be used. The exception only applies for the reach of 1 41 ORDINANCE NO. 4835 Springbrook Creek between SW 43rd Street and Oakesdale Avenue near SW 41st Street. c. Determining Finished Floor Elevations According to FEMA: { Although City model results will apply to compensatory storage requirements, the FEMA 100-year flood plain elevations shall be used to establish building finished floor elevations to comply with other National Flood Insurance Program requirements. J. GEOLOGIC HAZARDS: i 1. Applicability: In addition to the General Standards of RMC 4-3-050.E, the following performance standards, RMC 4-3-050.J.2.-J.8., apply to all f regulated geologic hazard areas, unless the subsection clearly identifies I that the standard applies only to a specific geologic hazard category. Multiple performance standards may apply,to a site feature, for example steep slope, landslide and erosion hazards, based upon overlapping classification systems. 2. Special Studies Required: Whenever a proposed development requires a development permit and a geologic hazard is present on the site of the proposed development or on abutting or adjacent sites within 50 feet of the subject site, geotechnical studies by qualified professionals shall be required. Specifically, geotechnical studies are required for developments proposed on sites with any of the following geologic hazards: a. Sensitive and protected slopes; b. Medium, high, or very high landslide hazards; c. High erosion hazards; 1 d. High seismic hazards; e. Medium or high coal mine hazards. 3. Independent Secondary Review: i a.

Elevations are from FEMA floodway data tables. (2)FEQ simulated flows at these locations are based upon frequency analysis of Springbrook Creek inflows to the BRPS forebay: Refer to ESGRWP Hydrologic Analysis Report(NHC. 1996) for flows based upon frequency analysis of Panther Creek and Rolling Hills Creek. ' (3)Flows are based upon assumption that capacity restriction through Renton Shopping Center is improved - such that no attenuation from surface ponding occurs. (4)u/s = upstream,d/s =downstream • (5)Rise in FEMA water surface elevation at SW 16th Street from the confluence of Rolling Hills Creek is due to unresolved discrepancy at the upstream boundary 61 1989 FEMA restudy(FEMA. 1989). (6)Conveyance event reflects a severe local rainstorm without pumping restrictions at the BRPS due to high Green River flows. Storage event reflects a high Green River flow event in which the BRPS must restrict pumping rates in accordance with GR1A. : y.

W3X32800\1102\Drainage Report 01 September 2000 EXECUTIVE SUMMARY The corporate office complex developed by The Boeing Company on the site of the former Longacres Park property in Renton, Washington, consists of the Customer Services TrainingCenter ("CSTC") and the Longacres Office Park ("LOP"). The CSTC g ) site was developed in 1993 and a portion of the LOP site was developed beginning in 1997. These developments included surface water management systems designed to serve the facilities being constructed, as'well as master plan facilities. In preparation for future development at LOP, Boeing proposes to enter into a development agreement with the City. The development agreement will describe the basic parameters of proposed office park development and will be based on the 1994 EIS and additional environmental analysis of certain aspects of the project (i.e., surface water management). The updated environmental analysis will also discuss additional impacts caused by increasing the height of certain buildings to achieve an increase in total gross square footage. This drainage report describes the conceptual drainage plan for the master plan at Longacres. The conceptual drainage plan will integrate with existing drainage facilities. Drainage Code This report is written to fulfill the requirements of the City of Renton Drainage Report for Conceptual Drainage Plan Content List. The analyses included herein'are based on the 1990 King County Surface Water Design Manual (KCSWDM), as adopted by the City of Renton. Each of the 5 Core Requirements and 13 Special Requirements are addressed herein, and the conceptual drainage plan will conform to these requirements. Water Quality Treatment Surface water runoff from master plan parking and roadway areas can be tre,ated to improve water quality in multi-stage systems, similar to previous Boeing developments at this property. These systems include catch basins with deep sumps, grit removal chambers that can accommodate future coalescing plate filters and combination wetpond/detention ponds. The majority of runoff will be treated in existing facilities that were sized for future master plan development. Under master plan conditions, existing Pond "A" (west of the CSTC Building) and Pond "C" (south of the Family Center Building) are proposed to be enlarged. A new pond, Pond "E," is proposed to serve the southern portion of the property. These ponds will be oversized in volume and surface area by 150 percent to compensate for not providing biofiltration facilities, in accordance with City policy. Water Quantity Control Most surface water runoff peak rate control can be provided by existing drainage facilities that were sized for future master plan development. Under master plan conditions, existing Pond "A" (west of the CSTC Building) and Pond "C" (south of the Family Center Building) are proposed to be enlarged to serve added tributary area. A new pond, Pond "E," is proposed to serve the southern portion of the property. The maximum elevation in existing ponds during storm events will not interfere with drainage from existing upstream facilities. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\Drainage Report Exec Summary i September 2000 Conveyance Surface water will be conveyed to the aforementioned water quality/quantity facilities via pipe networks, open channels and culverts in a manner similar to previous Boeing developments at this property. The master plan proposes a series of open channels from the SW 27th St. corridor northerly to existing Pond "D." These channels could be connected with culverts at master plan road crossings and could be vegetation-lined to integrate with adjacent master plan landscaping. Floodplain and Compensatory Storage Compensatory storage requirements are specified in City of Renton Ordinance No. 4835, "Compensatory Storage." The ordinance prohibits the reduction of effective base flood storage volume based on the higher of the City hydrologic and hydraulic model results for the 100-year future land use conveyance and storage events in Springbrook Creek. All pre-developed outfall pipes were protected by mechanical,flap gates, which prevented inundation of the property. Review of the City model indicates that the peak elevation in Springbrook Creek is generally less than the elevation of the ground along the creek adjacent to the property during pre-development conditions. Under such conditions, no storage volume was provided, and none must be maintained. Where this is not the case, master plan grading design could maintain the relatively small existing base flood storage volume. Groundwater Previous experience at this property indicates that groundwater can be very shallow, especially during the wet season. Groundwater must be considered during final master plan design, particularly with respect to construction activities and foundation design. Sensitive Areas Previous Boeing development at this site mitigated wetland impacts anticipated as a result of master plan development. Mitigation consisted of constructing wetlands on both the CSTC and LOP properties. In addition, the original South Marsh Wetland exists at the southeast corner of the property. Master plan development, will not disturb these wetlands. Treated and detained runoff from proposed Pond "E" will discharge in the buffer of the South Marsh Wetland in order to maintain discharge at the natural location and maintain wetland hydrology. This area of the site is also protected by a restrictive covenant that prohibits nearly all activities. No master plan development is planned within the area described by the restrictive covenant.

September 2000 W3X32800\1102\Drainage Report 01 ' PROJECT OVERVIEW • A. Introduction The corporate office complex developed by The Boeing Company on the site of the former Longacres Park property in Renton, Washington, consists of the Customer Services Training Center ("CSTC") and the Longacres Office Park ("LOP"). The CSTC site was developed in 1993. In 1994, Boeing submitted an EIS to the City describing the environmental impacts of a 164-acre, 2.5 million square foot master planned development including offices, an employee center, related support and utility facilities, and open space amenities at LOP. It was then estimated that the office park would be developed over a ten to fifteen year period according to Boeing's corporate needs, and would include approximately 10,000 employees at full build-out. In 1995, the City issued a Mitigation Document for the office park setting forth required mitigation for project development. Two buildings have been constructed since 1995 -- BCAG Headquarters (1997) and Renton Family Care Center (1998).1 In 1999, the Surface Water Management Project ("SWMP") was constructed. SWMP is a surface water management system for the office park consisting of a combination of wetponds, detention ponds and created wetlands sized to accommodate the master plan at full build-out. In preparation for site development, Boeing now proposes to enter into a development agreement with the City pursuant to the requirements of RCW 36.70B.170 through .210. The agreement will describe the basic parameters of proposed office park development and will be based on the 1994 EIS and additional environmental analysis of certain aspects of the project (i.e., impacts on traffic and storm water management). The updated environmental analysis will also discuss any additional impacts caused by increasing the height of certain buildings to achieve an increase in total gross square footage. The development agreement will also establish applicable development regulations, including development standards set forth in the Renton Code, a vesting framework, and other restrictions. This report is written to fulfill the requirements of the City of Renton Drainage Report for Conceptual Drainage Plan Content List. The analyses included herein are based on the 1990 King County Surface Water Design Manual (KCSWDM) as adopted by the City of Renton. I Boeing's Customer Services Training Center, completed in 1992, is located on a separate lot immediately north of the office park site. Development Agreement Project -Drainage Report for Conceptual Drainage Plan Sverdrup CMI,Inc. W3X32800\I 102\wp\Drainage Report 01.doc 1-1 September 2000 The Technical Information Report (TIR) Worksheets detailing site information and constraints to development are included as Figures 1, 2 and 3. The site location and vicinity maps are detailed on Figures 4 and 5, respectively. All figures are located at the conclusion of the written portion of the report, preceding the appendices. The proposed surface water management system described herein is designed to integrate with the existing elements of the surface water management system approved and constructed by Boeing as part of the following projects: • Surface Water Management Project ("SWMP") • Boeing Family Care Center ("FCC") Building 25-10 Site Development • BCAG ("BCAG") Headquarters Building 25-20 Site Development • Boeing Family Care Center ("FCC") Building 25-10 Site Development • Customer Services Training Center ("CSTC") and Support Facilities Site Development B. Project Datum The current City of Renton vertical datum is NAVD 1988 according to the City's Drafting Standards. However, all previous mapping, design, reports and studies completed for the CSTC and Longacres Office Park Sites were based on NGVD 1929 Sea Level datum, including all previous drainage reports. Additionally, the Federal Emergency Management Agency (FEMA) continues to utilize the NGVD 1929 datum for their Flood Insurance Rate Maps. Boeing and the City reached an agreement at the Mapping and Survey Control Meeting held at the City's offices December 12, 1996 allowing projects at Longacres to be completed based on NGVD 1929 vertical datum as long as FEMA continues to utilize the NGVD 1929 datum. This Report is based on assumed NGVD 1929 vertical datum. The conversion equation is: NGVD 1929 = +3.58' NAVD 1988 This conversion equation is provided for information only; it is not used within this report. Development Agreement Project -Drainage Report for Conceptual Drainage Plan Sverdrup Civil, leo. W3X32800\1102\wp\Drainage Report 01 1-2 September 2000 II PRELIMINARY CONDITIONS SUMMARY This Section includes a discussion of Core Requirements 1 - 5 and all Special Requirements from the King County Surface Water Design Manual (KCSWDM) as referenced in the City of Renton Drainage Report Content List (from the City's Drafting Standards). The City of Renton Building Regulations §4-22-8 formally adopt the current version of the KCSWDM, and amend them to include additional criteria for projects located within Zones 1 and 2 of the Aquifer Protection Area. The Aquifer Protection Area Map produced by RH2 Engineers, dated March 21, 1995, indicates that this project does not fall within the Aquifer Protection Area. The City of Renton has not adopted the 1998 King County Surface Water Design Manual. A. Discussion of Core Requirements 1. Core Requirement#1 -Discharge at the Natural Location The existing project site drains to Springbrook Creek, as shown in Figure B.1, and will continue to do so under master plan conditions, as shown in Figure C.1. The existing site drained to Springbrook Creek through five outfalls, as follows: i. Outfall No. 1 — Support Facilities Site Outfall. This outfall drained, and continues to drain, land north of SW 16th Street to Springbrook Creek via an open channel that outfalls at a location just north of the SW 16th Street Bridge. This basin was developed and an approved drainage system was constructed as part of the Customer Services Training Center (CSTC) Support Facilities Site Development Project. ii. Outfall No. 2 — Customer Services Training Center (CSTC) Site Outfall. This 36-inch outfall was reconstructed in its former location as part of the CSTC Site Development Project, and is protected against Springbrook Creek backwater events with an elastomeric check valve. This outfall drained, and continues to drain, the northern portion of the Longacres property. This contributing basin was developed and an approved drainage system was constructed as part of both the CSTC and BCAG Headquarters Building (BCAG) Projects. Improvements constructed as part of the Surface Water Management Project (SWMP) redirected runoff from Outfalls No. 3 and No. 4 (see below) to this outfall. Proposed master plan improvements within this contributing basin involve construction of additional buildings, parking and landscaping Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil. Inc. W3X32800\1102\wp\Drainage Report 01 II-1 September 2000 areas, as well as drainage networks that will serve these facilities. iii. Outfall No. 3 — Practice Track Site Outfall. This outfall drained the central portion of the Longacres property via a 36- inch outfall with a mechanical tide.gate. The outfall is located at the eastern property line. The contributing drainage basin was partially developed and an approved drainage system was constructed as part of the BCAG and Boeing Family Care Center (FCC) . Site Development Projects. Improvements constructed as part of the SWMP enlarged the detention and water quality facilities in this contributing basin and redirected runoff to Outfall No. 2. Proposed master plan improvements within this basin involve construction of additional buildings, parking and landscaping areas, as well as drainage networks that will serve these facilities. These improvements will also redirect the majority of runoff from this outfall to Outfall No. 2. iv. Outfall No. 4 — Breeders Pavilion Outfall. This outfall previously drained an area along the east property line in the vicinity of the former Breeders Pavilion. The outfall was a meandering ditch running easterly just south of the former practice track. This outfall probably only carried flow when water ponded to sufficient depth to overcome topographic features. All surface water runoff from the drainage basin contributing to this outfall will be redirected to Outfall No. 2 under master plan conditions. Proposed master plan improvements within this drainage basin involve construction of additional buildings, parking and landscaping areas, as well as drainage networks to serve these facilities. v. Outfall No. 5 — South Marsh Outfall. This 48-inch corrugated metal pipe (CMP) outfall drains the property located to the south of an extension of SW 27th Street. Under master plan conditions, the limits of the basin contributing to. this outfall will remain essentially unchanged. Proposed master plan improvements within this drainage basin involve construction of an additional building, parking and landscaping areas, as well as drainage networks to serve these improvements. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 II-2 September 2000 2. Core Requirement#2 - Off-Site Analysis The Level 1 off-site analysis for this project extends to. Springbrook Creek. Refer to Section III of this Report for more detail. 3. Core Requirement #3 - Runoff Control a. Peak rate runoff control The existing CSTC Main Pond and Pond "D" will provide the majority of detention for the fully developed site under master plan conditions. In addition, both Pond "A" and Pond "C" will be enlarged to accommodate additional contributing area created as a result master plan development. A new pond, Pond "E," will be constructed to serve the area at the south end of the property developed for master plan conditions. b. Biofiltration Construction of the master plan will require provision of biofiltration facilities because it will create more than 5,000 square feet of impervious surface subject to vehicular use and storage. According to City policy, when treatment pond volume and surface area exceed code requirements by a factor of 1.5, biofiltration is not required. The site will be developed to meet this factored requirement, thereby eliminating the need to provide biofiltration. Refer to Appendix F for more detail. c. Existing site conditions As defined within this Core Requirement, the existing site conditions are defined as those that existed prior to May 1979 since the project area never had an approved drainage system. Existing conditions are documented by aerial photography and field surveys. These sources indicate that existing conditions at the property generally consisted of a horse racing facility, including the main racing track, grandstands, horse barns, support buildings, meadow areas, a practice track and parking areas. Development Agreement Project-Drainage Report for Conceptual Drainage Plan - Sverdrup Civil. Inc. W3X32800\I IO2\wp\Drainage Report 01 11-3 September 2000 d. Peak rate runoff control performance Peak rate runoff from the developed site was evaluated for 2-, 10-, and 100-year storm events. Runoff release rates for post-development conditions will be less than or equal to pre-development release rates. Refer to Section IV for more detail. This project site is exempt from more restrictive runoff performance curves because lakes, wetlands and closed depressions, as described under Special Requirement No. 8, are not used for peak rate runoff control. e. Detention facilities Detention for the developed site will be accomplished in combination wetpond/detention Ponds "A," "C," "D," "E," "N," and the CTSC Main Pond. Retention and infiltration facilities are not planned at this site. f. Bypasses A negligible quantity of on-site runoff will bypass detention facilities under master plan conditions. In addition, the discussion under Core Requirement No. 1 and Section IV(B) documents how detention can be provided for runoff that will be redirected to different outfalls due to master plan development. All off-site runoff will bypass master plan runoff control facilities. Off-site runoff only enters the property at the South Marsh Wetland, as described in Section III(D). 4. Core Requirement #4 - Conveyance Systems Master plan conveyance systems may consist of pipe networks, culverts and open channels designed to convey the on-site peak rate runoff for the 100-year 24-hour design storm. Some surcharging may occur during 100-year 24-hour design events, while the 25-year 24-hour event will be conveyed without surcharge. See Section V of this Report for more detailed information. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Chill,Inc. W3X32800\I 102\wp\Drainage Report 01.doc lI-4 September 2000 5. Core Requirement#5 -Temporary Erosion/Sedimentation Control Engineered drainage plans will be required for master plan development, hence, temporary erosion/sedimentation control (TESC) measures in accordance with Core Requirement#5 will be required. The 11 minimum requirements, KCSWDM Standard Plan Notes and the.City of Renton Standard Plan Notes must be addressed by the Erosion/Sedimentation Control Construction Drawings. For more detail, refer to Section VII of this Report. B. Discussion of Special Requirements 1. Special Requirement#1 - Critical Drainage Areas The proposed project site does not lie within a designated critical drainage area as indicated within Reference 3 Critical Drainage Area Requirements of the KCSWDM, therefore this special requirement does not apply. 2. Special Requirement #2 - Compliance with an Existing Master Drainage Plan A formal Master Drainage Plan has not been prepared or approved for this project site. However a conceptual site Master Drainage Plan was previously transmitted to the City of Renton. The draft plan included the majority of existing drainage facilities already constructed at the property, as .well as additional conveyance facilities south of the enlarged CSTC Main Pond. Master plan development remains in compliance with the Draft Master Drainage Plan and maintains the drainage corridor along the center of the property (along a north-south axis). 3. Special Requirement #3 - Conditions Requiring Master Drainage Plan This special requirement may apply, as the proposed master plan development project: a. is a commercial development that proposes to eventually construct more than 50 acres of impervious surface. Development Agreement Project-Drainage Report for Conceptual Drainage Plan - Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 II-5 September 2000 If the City of Renton determines that a Master Drainage Plan (MDP) is required for the proposed master plan, this report can l serve as the basis for the two major components of the MDP; the Technical Report and the Preliminary Plan. Depending upon the level of detail desired by the City, this report may be considered sufficient for both components. This report details drainage . control systems that will prevent significant adverse impacts to the site's natural hydrologic system and to off-site drainage systems. The other three elements of this special requirement do not apply, as the proposed master plan development project: a. is not within a Master Planned Development (MPD) as described in an adopted Community Plan; OR b. is not a subdivision or Planned Unit Development (PUD) that will eventually have more than 100 single-family residential lots and encompass a contiguous drainage subbasin of more than 200 acres; OR c. will not clear an area of more than 500 acres within a contiguous drainage subbasin. 4. Special Requirement#4 - Adopted Basin or Community Plans - No Adopted Basin or Community Plan exists for this area, therefore this special requirement does not apply. 5. Special Requirement#5 - Special Water Quality Controls Under master plan development, more than 1 acre of new impervious surface will be constructed for vehicular use and storage of chemicals, therefore this special requirement will apply. Design of wetponds are further discussed in Section IV, Part E of this Report. The wetpond volume and surface area exceed that required by at least a factor of 1.5 to compensate for not providing biofiltration. 6. Special Requirement#6 - Coalescing Plate Oil/Water Separators This property will not be subject to petroleum storage or transfer or heavy equipment use, storage or maintenance. However, the estimated traffic at this property under master plan conditions will exceed 2,500 vehicle trips per day, therefore, this special requirement will apply. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 II-6 September 2000 Previous drainage systems constructed at this property incorporated precast concrete vaults sized to accommodate future coalescing plate oil/water separators. These vaults are located in parking areas such that all parking lot runoff low flows are directed to the vault, . while high flows are bypassed. However, based on satisfactory water quality measurements, no separators have been installed to date. During detailed design of future improvements, the requirement to provide for these separators should be discussed with the City of Renton. Such discussions should include specific subcatchment areas that may not be subject to the threshold vehicle trip rate. 7. Special Requirement#7 - Closed Depressions R.W. Beck and Associates .reviewed the adjacent CSTC Site Development design for conformance with City and FEMA requirements in a technical memorandum dated September 11, 1992. Within Section III(B)2d of that memorandum, it was stated that "it should be noted that although Springbrook Creek does have a restricted outlet (due to the [Green .River Management Agreement] GRMA), such restrictions have occurred so infrequently that [the site] should not be considered a closed depression." Springbrook Creek can reach elevations that temporarily restrict drainage from the site. These high water elevations on. Springbrook Creek are taken into account within conveyance system backwater. analyses. For more detailed information, see Section V(B)2 of this report. 8. Special Requirement #8 - Use of Lakes, Wetlands or Closed Depressions for Peak Rate Runoff Control The CSTC Main Pond is the existing constructed wetland at the northern central portion of the property that provides the majority of peak rate runoff control for the property. Along with combined wetpond/detention ponds "A", "D" and "N", the ponds were designed to provide peak rate runoff control for the CSTC Building 25-01 site and the Headquarters Building 25-20 site, as well as all future master plan developments west of Oakesdale Avenue SW and north of the SW 27th Street corridor. The CSTC Main Pond will continue to drain into the CSTC Delta area under master plan conditions. The CSTC Delta area is a constructed wetland area designed to accept stormwater flows from the upstream site. The Delta forms the downstream end of'a system to be constructed as the development of the Longacres Office Park site progresses. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 I1-7 September 2000 The property south of the SW 27th Street corridor will be served by proposed master plan combination wetpond/detention Pond "E." This pond will drain to the existing wetland at the southeast corner of the property. This wetland will receive flow from Pond "E" that has been detained to match existing conditions, therefore, it will not provide a detention function. 9. Special Requirement#9 -Delineation of 100 Year Floodplain This project site is in the vicinity of Springbrook Creek, which has an associated floodplain based on Federal,Emergency Management Agency (FEMA) Flood Insurance Rate Map Panel 53033C0978F. This project is outside the limits of the floodway but is within the flood fringe, or that portion of the plain outside the floodway which is covered by flood waters during the base flood. The FEMA floodplain and compensatory storage evaluation are discussed in Section VI of this Report and more detailed information about the floodplain, including mapping, is included in Appendix A. 10. Special Requirement #10 - Flood Protection Facilities for Type 1 and 2 Streams No existing flood protection facilities exist for the portion of Springbrook Creek adjacent to the project, therefore this special requirement does not apply. 11. Special Requirement#11 - Geotechnical Analysis and Report Prior to design of major master plan facilities, a geotechnical report will be required. Many geotechnical reports have previously been prepared for past projects at this property. They are: a. "Report, Supplemental Geotechnical Engineering Services, CSTC Pond Expansion, Boeing Longacres Park, Renton Washington," (GeoEngineers, January 22, 1999). This report included analysis of soil parameters of the material at the bottom of the existing CSTC pond as well as in the vicinity of the SWMP site excavation for permeability and reuse potential. b. "Report, Supplemental Hydrogeologic Services, Surface Water Management Project, Boeing Longacres Park, Renton Washington," (GeoEngineers, January 22, 1999). This report included analysis of a dewatering test well Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 II-8 September 2000 program, dewatering well discharge quality and quantity and dewatering well drawdown characteristics. c.

The Green River is the largest and is located in the City of Tukwila, Washington, about 1,200 feet west, and west of the West Valley Highway (State Highway Route 181). The Green River has a levee system along its banks protecting nearby property. The flow is partially regulated by the Corps of Engineers' Howard A. Hanson Reservoir near the headwaters of the River. Controlled flow releases, coupled with the levee system provides protection of the site from the Green River for at least a 100-year flood. In the vicinity of the property, the West Valley Highway is higher than the levee system adjacent to the River providing additional flood protection. ' The second predominant waterway is Springbrook Creek (located to the east of the site), a tributary of the,Black River (which is tributary to the Green River). All stormwater from the site flows easterly to Springbrook Creek. The site is within the watershed of Springbrook Creek, and portions are also within the floodplain of the creek according to Federal Emergency Management Agency (FEMA) mapping. The stream channel for Springbrook Creek. (also known as the P-1 Channel) was previously reconstructed downstream of the Oakesdale Ave. SW Bridge. 2. Green River The watershed area of the Green River above Renton is 450 square miles. Above the Howard A. Hanson Dam the watershed area is 215 square miles. The Green River flow is controlled by the Corps of' Engineers, Seattle District, which is responsible for the. regulation of dam outflows from the Howard A. Hanson Dam at Eagle Gorge on the upper Green River. The regulation limits the flow at Auburn to less than 12,000 cfs for up to a 500-year storm frequency. This flow rate represents a 2-year recurrence flood event if the stream was not regulated. The flood profiles for the Green River in the vicinity of the Longacres site indicate the same flood elevation for both the 10-year and the 500-year flood frequency. FEMA flood profiles are presented in Appendix A. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil. Inc. W3X32800\1102\wp\Drainage Report 01 III-1 ' September 2000 Flood profiles of the Green River with and without levees generally indicate the same elevation of 23.2 feet in the vicinity of the Longacres Park site, opposite S. 158th Street (Longacres Way). Elevation 23.2 is significantly below the West Valley Highway, which is at approximately elevation 25 to 29 adjacent to the project site. Therefore, floodwater from the Green River will not enter the site during a 500-year or lesser flood. On July 18, 1985, the Green River Management Agreement was entered into by King County and the cities of Auburn, Kent, Renton, and Tukwila. This agreement was updated in 1992 and generally outlines and provides guidelines for improvements, monitoring, operations, and financial responsibilities. Important operating procedures are presented for the P-1 pump station, including maximum pumping rates from Springbrook Creek/Black River as follows: Black River (P-1) Pumping Operations Limits Measured Green River Black River (P-1) Flows at Auburn Maximum Allowable Pumping Gage (cfs) ' . (cfs) Less than 9,000 cfs As required 9,000 cfs 2,945 cfs (1) 9,500 cfs 2,900 cfs 10,000 cfs 2,400 cfs 10,500 cfs ' 1,900 cfs 11,000 cfs 1,400 cfs 11,500 cfs 900 cfs 12,000 cfs See Note (2) Note 1: Assumes full installed capacity is available. Note 2: Maximum allowable pumping rate is 400 cfs to zero depending on levee monitoring, by King County Director of Public Works or his designee. Further restrictions on P-1 pumping capacity may be required per the Pumping Operations Plan. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 III-2 September 2000 3. Springbrook Creek The confluence of Springbrook Creek with the Black River is established by FEMA as the upstream end of the P-1 storage bay of the Black River. This confluence point is.0.6 miles upstream of • the Black River P-1 pumping station and 1 mile upstream of the confluence of the Black River with the Green River. The watershed area of Springbrook Creek is 21.9 square miles with the following peak discharges: Peak Discharges CFS at Confluence Design Storm Event Peak Discharge Rate (cfs) 10-year 590 50-year 930 100-year 1,100 500-year 1,550 In the area of the project site the 100-year flood elevation is indicated as 16.4 at SW 16th Street and 16.0 at SW 23rd Street. This is because the 1989 FEMA update for lower Springbrook Creek only extended up to SW 16th Street. The drop in flood elevation upstream of SW 16th Street is a discrepancy between the 1989 FEMA update and the previous study that was not resolved. The FEMA flood boundary map and the site contours as field mapped are shown in Appendix A. The flooding elevation of 16.4 is obtained by using the 875 cfs capacity of the P-1 pump station in operation at the time of the FEMA study assuming no pumping restrictions from flooding on the Green River when a 100-year flood occurs on Springbrook Creek. The highest elevation occurs in the forebay when the flood flow is less than the peak of 1,100 • cfs, during the downward leg of the hydrograph at a flow rate of approximately 785 cfs. This high water elevation in the forebay is 15.0. This elevation is used in a HEC-2 (Hydraulic Engineering Model for Floodway Water Surface Profiles) to generate upstream water levels to SW 16th Street. This results in an elevation of 16.42 at the SW 16th Street bridge. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\I 102\wp\Drainage Report 01 III-3 September 2000 The FEMA data does not include provisions for the SW 16th Street Bridge with a 60-foot span compared to the old span of 36 feet. It also does not include the multi-barrel box culvert under Grady Way, the box culvert constructed under I-405 or the completed P-1 Channel cross section from the mouth of Springbrook Creek up to the SW 16th Street bridge. The City of Renton authorized R.W. Beck and Associates, Inc. to complete the "East Side Green River Watershed Project Hydraulic Analysis Report," dated December 1996. This report recognizes conditions beyond those of the FEMA studies, such as the current Black River Pump Station operation plan, Black River Pump Station capacity, P-1 channel improvements, future land use conditions, the proposed City of Kent Lagoons project, and other infrastructure improvements planned by the City of Kent and the Washington State Department of Transportation. The result of these improvements and future development result in Springbrook Creek water surface elevations considerably lower than those reported by FEMA. In fact, the most extreme water surface elevation reported is approximately 13.2 at the practice track outfall under future 100-year, "storage" conditions assuming no further capacity improvements. This is 3.2 feet lower than that reported by FEMA. These elevations are summarized .in Appendix G. As discussed in Section VI(C) of this report, the City of Renton now utilizes the results of it's latest modeling to determine flood elevations for the purpose of compensatory storage. The City of Renton recently completed additional Springbrook Creek channel improvements from SW 16th Street upstream to the Oakesdale Ave SW Bridge. These improvements were made at the same time as the Oakesdale Avenue SW project to limit disturbance to the creek, wetland areas and adjacent property owners. Also, the SW 27th Street Bridge at Springbrook Creek was recently replaced with a precast concrete structure that provides improved channel capacity. The improvements will somewhat reduce flood elevations from those currently modeled, by improving channel capacity and storage volume.

Black River The Black River as it exists today is 1 mile in length and its confluence with the Green River is 11.0 miles upstream of Puget Sound. A pumping station is located on the Black River 0.3 miles upstream of its confluence with the Green River. The watershed area at the pump station is 24.8 square miles which includes the 21.9 square miles of Springbrook Creek. The pumping station has no gravity flow provisions. All upstream flows must be pumped up to a gravity open channel that discharges to the Green River. The fully installed nominal rated pumping capacity of the station is 2,945 cfs. There are eight main pumps with one of the larger pumps currently off-line. There are five diesel pumps rated at 514 cfs, two diesel pumps at 150 cfs, and one automated electric pump rated at 75 cfs. The FEMA study was based on the nominal installed capacity at the time of 875 cfs as the pump station's firm capacity of maximum discharge. The pump station has a forebay (called the P-1 pond storage area) that was expanded by excavation in 1984. The pump station's current installed nominal operating capacity is 2,431 cfs. The 1989 FEMA study indicates that peak outflows from the pump station had not exceeded 525 cfs (November, 1986 event with nominal P-1 pond storage). On March 4, 1991, the pump station operator indicated he was pumping at a rate of 750 cfs. During the February 1996 event the pump station operator had to operate 1 large pump, the two medium pumps, and the small pump for a combined nominal capacity of 889 cfs. According to the pump station's operating plan, the first large pump is to be activated when the level in the forebay reaches elevation 4.0. According to FEMA, a Green River flow of 12,000 cfs equates to elevation 19.0 downstream of the pump station. The pump room floor elevation is 25.0 NGVD. Since all upstream flow must be pumped the electric pumps are automated by float switches. The larger diesel pumps must be manually started and are used as required to pump out the storage pond. Trash racks are cleaned periodically depending on the debris build-up. There have been some flap gate failures with the rocker arm breaking off. However, the pump bays can be isolated from backflow with stoplogs. • Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 III-5 September 2000 An upstream fish ladder at the pump station is operated during the upstream migration period from mid-September through January. Between early April and mid-June the downstream migration is accommodated by an air lift system. A simplified fish counter consisting of a paddle in the upstream migration trough counts electronically the number of fish passing. Historical fish counts are as follows (H. Allmendinger, personal communication): Black River Fish Counts Season Number of Fish 83-84 155 84-85 119 85-86 47 86-87 82 87-88 166 88-89 95 89-90 77 90-91 70 91-92 107 92-93 291 93-94 120 94-95 268 95-96 355 96-97 206 97-98 265 98-99 84 99-00 395 B.

Task 2: Resource Review In accordance with the requirements of Task 2 of the Off-Site Analysis Section of the King County Surface Water Design Manual, the following table shows the resources reviewed regarding existing and potential flooding and erosion problems for the project area: • Resource Findings Basin Reconnaissance Summary Reports The City has extensively studied the East Side Green River Watershed and produced the Draft East Side Green River Watershed Project,Plan and Environmental Impact Statement,December 1996. This report includes information related to existing and proposed conditions within the basin,proposed improvements,and hydrologic and hydraulic analyses of these conditions. Critical Drainage Area Maps As described above,the property is within the East Side Green River Watershed. FEMA Floodplain Maps Flood Insurance Rate Map Panel 53033C0978F (revised May 16, 1995). This property is outside the limits of the Springbrook Creek floodway but is within the flood fringe,or that portion of the plain outside the floodway which is covered by flood waters during the base flood. King County Sensitive Areas Folio Wetlands-No portions of the property are listed as wetland areas in the folio, however,the property includes several constructed wetland areas as well as an existing wetland area. Stream and Flood Hazard Areas-No portions of the property are indicated to be within streams or 100-year floodplains,however,the project does drain to Springbrook Creek,which is a Class 2(with salmonids). However,the most recent information from the King County sensitive areas database incorporates FEMA floodplain mapping and indicates that portions of the project are within the 100-year floodplain. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil. Inc. W3X32800\1102\wp\Drainage Report 01 III-7 September 2000 Resource Findings Erosion Hazard Areas-No portions of the property are classified as erosion hazard areas. Landslide Hazard Areas-No portions of the property are classified as landslide hazard areas. Seismic Hazard Areas- No portions of the property are considered seismic hazard areas. Coal Mine Hazard Areas-No portions of the property are considered coal mine hazard areas. Renton SWM Division Drainage Services No problems are documented at this site. All Problem Database drainage,flooding or erosion problems within the Springbrook Creek main stem are being addressed by the City's channel improvement projects. USDA King County Soils Survey This information is shown in the drainage basin mapping of Appendix B and C. Most of the project site soils are classified as Urban Land. D. Task 3: Field Inspection Sverdrup completed a field visit August 25, 2000. The temperature was about 65°F and the sky was overcast. There was occasional light precipitation. According to on-site weather station records, total precipitation for the 8 days preceding the August 25th field investigation was 0.31 inches (the NOAA records for Sea-Tac Airport for this same period report 0.28 inches). The investigation revealed that existing drainage systems constructed by Boeing as part of their CSTC, Headquarters, Family . Center and Surface Water Management Projects were in excellent condition and showed no evidence of flooding, erosion or plugging. All open areas were stabilized, either with healthy vegetation or with clean pavements and surfaces. The Springbrook Creek outfalls serving the Support Facilities, CSTC and Family Center areas were functioning properly and were not blocked or showing signs of erosion. No water was being discharged from these outfalls at the time of the field visit. Areas that have not been improved since the site was last used as a horse racing facility tend to be difficult to inspect due to thick vegetation, but no evidence of flooding, erosion or plugging was apparent. Outfall No. 4 (the former Breeders Pavilion Outfall) is no longer operational as a result of construction of Oakesdale Ave. SW. Any flow that could have drained,via this outfall probably ponds until it can reach catch basins that direct the flow toward Outfall No. 3. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 III-8 September 2000 �. Outfall No. 5 (the South Marsh Outfall) was overgrown with thick vegetation but shows no sign of plugging or erosion. This culvert is constructed at a reverse slope, and the upstream invert has at least 6 inches of sediment in it, while the downstream invert has less sediment. The material does not appear to restrict drainage from the South Marsh. From the culvert, flow must travel easterly through City of Renton Wetlands 12A/12B before it can reach Springbrook Creek. Runoff can pond in the City's wetland area, but it does not appear to cause problems on adjacent property. There is no evidence of erosion in the City's wetland, nor along Springbrook Creek. Finally, it appears that at the very southeast corner of the property, an offsite channel draining land to the south could contribute runoff to the South Marsh. This situation would occur only when offsite flow ponded to sufficient depth to overcome the topography along the property line. There is no evidence that such overtopping has occurred recently. E. Drainage System Description and Problem Screening There are no significant constructed drainage systems serving the undeveloped portions of the property. The northwestern portion of the property is a gravel and paved parking area served by several catch basins and pipelines that drain easterly to the CSTC Main Pond. All other undeveloped areas simply drain via sheet or shallow concentrated flow. There is no evidence that the lack of formal drainage systems in such areas are detrimental or require improvement at this time. F. Mitigation Improvements proposed as part of the master plan will encompass all undeveloped areas of the property except the South Marsh, therefore the site drainage systems will ultimately be improved and require no specific mitigation. It is our understanding that the City of Renton will improve the culvert draining the South Marsh as part of the Oakesdale Ave. SW Phase 2 Extension Project, which is currently being designed. G.

Existing (Pre-Development)Site Hydrology The Longacres property is located in the City of Renton. The property is located between the Burlington Northern Railroad on the west and the Springbrook Creek Channel on the east. To the north is Interstate 405 and to the south is undeveloped land, extending to approximately 800 feet south of the SW 27th St. corridor. The property was previously a horse racing facility. The site included the main racing track and practice track, grandstands, offices, breeder/sale pavilion, roads, parking lots, support buildings, barns, landscape and fields. .The majority of the property is relatively level with elevations generally between 11 and 25. The property drains easterly to Springbrook Creek. Boeing made improvements to the property during the 1990's. The improvements affecting topography and drainage have been documented in previous drainage reports and are not described in detail herein except as necessary to explain how they will integrate with master plan development. The following discussion details the property before such improvements were made by Boeing. The pre-development drainage basins for the property are shown in Appendix B, Figure B.1. Four on-site basins are impacted by the proposed master plan development; Basins 3, 4, 5 and 6. Basin 1 is an upstream, off-site basin located west of the Burlington Northern Railroad that will not be impacted by any future work. Basin 2 is the Support Facilities Basin located north of SW 16th St. that will not be impacted by future master plan development. More information about these basins can be found in the CSTC Site Development TIR. 1. 'Basin 3 -North Main Track Basin This basin is detailed in Figure B.1, Appendix B. It included 78.7 acres and drained to Outfall No. 2, the Customer Services Training Center (CSTC) Outfall. The majority of this basin was formerly the northern portion of the main racing oval and its infield. Also included in the basin were grandstands, offices, horse barns, horse walking areas, fields, roads, parking and support buildings. The area also included wetlands. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 IV-1 September 2000. Runoff traveled from parking areas to catch basins and through pipes to the racetrack infield swales. From the infield, flow continued easterly under the horse barn area and ultimately drained to Springbrook Creek about 450 feet south of the SW 16th St. Bridge. 2. Basin 4 - South Main Track Basin This basin is detailed in Figure B.1, Appendix,B. It included 84.5 acres and drained to Outfall No. 3, the Practice Track Site Outfall. The majority of this basin was formerly the southern portion of the main racing oval and its infield. Also included in the basin were horse barns, horse walking areas, fields, roads, parking and support buildings. The area also included wetlands. 3. Basin 5 —Breeders Pavilion Basin This basin is detailed in Figure. B.1, Appendix B. It included 15.3 acres and formerly drained to Outfall No. 4, the Breeders Pavilion Outfall. This basin included the Breeders Pavilion, horse barns, horse walking areas, roads and parking areas. Runoff from the basin drained to a meandering ditch running easterly just south of the former practice track, eventually reaching Springbrook Creek. This outfall probably only carried flow. from Longacres during larger storm events when water ponded to sufficient depth to overcome topographic features. Construction of Oakesdale Ave. SW has eliminated the original outfall from this basin. 4. Basin 6—South Marsh Basin This basin is detailed in Figure B.1, Appendix B. It included 31.4 acres and drained to Outfall No. 5, the South Marsh Outfall. This basin includes the area south of the SW 27th St. alignment, about half of which was grassy and possibly utilized as an overflow parking area. The other half of the basin is the South Marsh Wetland. The wetland area has an associated buffer zone and the wetland is protected by a restrictive, covenant the prohibits nearly all activities that would be associated with development. Hydrographs were developed for the pre-development site conditions for the Water Quality Event, the 2-, 5-, 10-, 25-, 50-, and 100-year, 24-hour events. A summary of these hydrographs and site parameters used to generate them are detailed in Appendix B. Detailed information is also provided in Appendix B, including soil groups, hydrologic soil groups, runoff curve numbers, existing land use descriptions, areas of each {' Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 IV-2 September 2000 particular land use, time of concentration.parameters and detailed basin (hydrograph) reports. B. Developed (Master Plan) Site Hydrology The post-development property drainage basins are shown in Appendix C, Figure C.1. As noted in the previous section, the major elements of the master plan surface water management system have been constructed, and master plan drainage basins are already partially in place. Following construction of the master plan, on-site basin limits will be further modified, and pre-development Basins 4 and 5 will generally be re- routed to the outfall that served Basin 3 under pre-development conditions. This means that the majority of the Longacres property will be treated by Pond "D," the CSTC Main Pond and the Delta Area prior to release from the CSTC Site Outfall. The master plan also includes separate treatment systems for runoff generated in Basin B (east of Oakesdale Ave. SW) and in Basin C (south of the SW 27th St. alignment). 1. Basin A - CSTC Site Basin The boundaries of Basin A generally match those of pre- development Basin 3, except that pre-developed Basins 4 and 5 will be merged and added to it, forming a single, larger Basin A. Master plan Basin A total area is 168.5 acres. The basin is shown in Appendix C, Figure C.1. This basin include existing buildings, parking, roadways, landscape and open water areas. Under master plan development conditions, runoff in this basin will originate in parking and landscape areas, or from building roofs, and will be conveyed toward one of three combined wetpond/detention ponds. Runoff from the northern portion of the basin will be conveyed and treated in facilities already constructed as part of previous Boeing projects at Longacres. Runoff from the southern portion of the basin will be conveyed in master plan pipelines, culverts and open channels from future buildings, parking areas, roads and landscape to Pond "D." From Pond "D," runoff will travel northerly to the CSTC Main Pond, then easterly to the Delta Area, where flow will outfall to Springbrook Creek via the CSTC Site Outfall. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Chill,Inc. W3X32800\1 IO2\wp\Drainage Report 0I.doc IV-3 September 2000 • 2. Basin B —Family Center Basin The boundaries of Basin B are Oakesdale Ave. SW to the west, the Delta Area to the north, and the property lines to the east and south. Basin B is the post-development version of pre- development Basin 4, but significantly smaller, as a result shifting . tributary area to Basin A. Basin B will include 14.1 acres upon final development. The basin is shown in Appendix C, Figure C.1. Basin B includes the existing Boeing Family Center and the existing combination wetpond/detention Pond "C." Under master plan conditions, the southern end of the basin will be developed as an electrical substation and paved parking area. Runoff from these master plan facilities will be collected and conveyed to an enlarged Pond "C," resized to accommodate the added tributary area. Revised Pond "C" will continue to drain via pipeline to an outfall at the east property line. 3. Basin C— South Marsh Basin The boundaries of Basin C are essentially the same as pre- development Basin 6. Minor basin .boundary changes are due to the proposed internal roadway that follows the extension of the SW 27th St. alignment. Basin C will include 31.4 acres upon final development. The basin is shown in Appendix C, Figure C.1. The portion of Basin C protected by the restrictive covenant (essentially the South Marsh Wetland) will remain undeveloped as part of the master plan. The area upstream of the wetland will be the site of a building with parking, landscaping and walkways. Runoff from these areas will be collected and conveyed to master plan Pond "E." Pond "E" will be a combined wetpond/detention pond, and it will out outfall to the wetland buffer without impacting the wetland. Post-development hydrographs were developed for Basins A, B and C for the Water Quality Event, the 2-, 5-, 10-, 25-, 50-, and 100-year, 24-hour events. A summary of these hydrographs and site parameters used to generate them are detailed in Appendix C. Detailed information is also provided in Appendix C. including soil groups, hydrologic soil groups, runoff curve numbers, existing land use descriptions, areas of each particular land use, time of concentration parameters and detailed basin (hydrograph) reports. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1 102\wp\Drainage Report 01 IV-4 September 2000 C. Hydrologic Analysis 1. Hydrograph Method In accordance with Chapter 3 "Hydrologic Analysis" of the KCSWDM, the hydrologic analyses in this report are based on a single-event SCS-type model known as the Santa Barbara Urban Hydrograph (SBUH) method along with the User 1 design storm rainfall distributions. This design storm hyetograph was interpolated by King County Surface Water Management Division staff, and resolved to 10-minute intervals. Discussions with King County staff indicate that the distribution shown on page 3.5.1-2 of the King County Surface Water Design Manual (and termed Type 1A) is actually a slightly modified version of the SCS Type 1A, and they consider it the "User 1" distribution. All analyses in this report utilize the User 1 distribution, which is identical to the KCSWDM's definition of a Type lA distribution. 2. Computation Software All SCS runoff curve numbers are based on Table 3.5.2B of the KCSWDM, and are tabulated and combined for input into the hydrology-software with a spreadsheet created by Sverdrup Civil, Inc. Time of concentration calculations are also computed by a spreadsheet, in accordance with page 3.5.2-5 of the KCSWDM.

Retention/Detention System 1. Overview Detailed calculations for the master plan combination wetpond/detention ponds are included in Appendix D. a. Pond "A" Following construction of the master plan, the western . portion of the CSTC Site and areas further west will drain to Pond "A," which in turn drains to the CSTC Main Pond. Existing Pond "A" will be enlarged to treat additional tributary area from master plan development, and is a combination wetpond/detention pond facility. It will have a dead storage volume of 41,900 cubic feet from El 4.0 to 9.0, not including the bottom one foot of depth reserved for sediment storage. Pond "A" will have a live detention storage volume of 14,600 cubic feet from El 9.0 to 10.0. b. Pond "C" Following construction of the master plan, the area east of Oakesdale Ave. SW and south of the Delta Area will drain to Pond "C," which outfalls at the east property line. Existing Pond "C" will be enlarged to treat additional tributary area from master plan development, and is a combination wetpond/detention pond facility. It will have a dead storage volume of 23,300 cubic feet from El 8.0 to 11.0, not including the bottom one foot of depth reserved for sediment storage. Pond "C" will have a live detention storage volume of 22,400 cubic feet from El 11.0 to 13.0. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil. Inc. W3X32800\1102\wp\Drainage Report 01 IV-6 September 2000 c. Pond "D" Following construction of the master plan, the majority of area west of Oakesdale Ave. SW and north of SW 27th St. will drain to Pond "D," which in turn drains to the CSTC Main Pond. Existing Pond "D" is a combination wetpond/detention pond facility and has a dead storage volume of 264,000 cubic feet from El 3.0 to 8.5, not including the bottom one foot of depth reserved for sediment storage. Pond "D" has a live detention storage volume of 366,000 cubic feet from El 8.5 to 12.0. d. Pond "E" Following construction of the master plan, the area south of SW 27th St. will drain to Pond "E," which will outfall to the South Marsh, which in turn will drain to the City of Renton Wetlands 12A/12B east of the Oakesdale Ave. SW alignment. Pond "E" will be a combination wetpond/detention pond facility and will have a dead storage volume of 53,200 cubic feet from El 12.0 to 15.0, not including the bottom one foot of depth reserved for sediment storage. Pond "E" will have a live detention storage volume of 46,100 cubic feet from El 15.0 to 17.0. e. Pond "N" Existing Pond "N" is a combination wetpond/detention pond facility that serves the eastern portion of the CSTC Site and drains to the CSTC Main Pond. Master plan development will not impact Pond "N." f. CSTC Main Pond Following construction of the master plan, the area south of SW 16th St (including the street itself), west of Oakesdale Ave. SW and north of SW 27th St. will drain to the CSTC Main Pond. The CSTC Main Pond has a dead storage volume of 1,190,000 cubic feet from El 3.0 to 8.5, not including the bottom one foot reserved for sediment storage, and a live detention storage volume of 1,504,000 cubic feet from El 8.5 to 12.0. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\I IO2\wp\Drainage Report 01 IV-7 September 2000 g. Delta Area The Delta Area receives flow from the CSTC Main Pond. The existing Delta Area has a dead storage volume of 98,000 cubic feet from El 4.0 to 7.5, and a live detention storage volume of 745,000 cubic feet from El 7.5 to 12.0. Construction of the master plan will not affect the configuration of the Delta Area. 2. Pond Control Structures a. Existing Control Structures Control structures are in place at Ponds "A," "C," "D," and "N." Details of these structures have been documented in previous drainage reports. The structure at Pond "C" will be reconstructed to serve the enlarged Pond "C." b. Proposed Control Structures Release from Pond "C" will be governed by the Pond "C" control structure. This structure will be reconstructed as necessary to accommodate the enlarged pond and increased tributary area. Preliminary design of the structure indicates that a 15-inch riser with 6.5- to 11-inch orifices will meet the desired performance criteria. Refer to Appendix D for preliminary design calculations for Pond "C." Release from Pond "E" will be governed by the Pond "E" control structure. Preliminary design of the structure indicates that an 18-inch riser with three 8-inch orifices will meet the desired performance criteria. Refer to Appendix D for preliminary design calculations for Pond "E." 3. Hydrograph Routing The portions of the property affected by master plan development lie within pre-development Basins 3, 4, 5 and 6, and post- development Basins A, B and C. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup CIVIL Inc. W3X32800\I 102\wp\Drainage Report 01.doc IV-8 September 2000 a) Pre-Development Basin 3 and Post-Development Basin.A Pre-development Basin 3 will become post-development • Basin A under master plan conditions. For pre-development conditions, Basin 3 was routed through 970 feet of 36-inch corrugated metal pipe (CMP) to model the outflow from the infield of the original main racing track to Springbrook Creek (at the location of the CSTC Site Outfall). The outfall was a 36-inch corrugated metal pipe with a mechanical flap gate. The majority of the master plan drainage system within the limits of this pre-development basin have been designed, approved and constructed. The system.consists of catch basins, pipelines, grit removal vaults and building rainwater leaders. These facilities drain to the combined wetpond/detention ponds "A", or "D" or "N," and then the CSTC Main Pond. Flow leaves the CSTC Main Pond and passes over a notched weir before entering the Delta Area and flowing to the CSTC Site outfall. The CSTC Site outfall is,made up of a precast concrete vault structure housing a timber weir and fish screen that directs stormwater under a public pathway and vegetated bank through a 36-inch ductile iron pipe with an elastomeric check valve at a riprap-protected outfall. More detailed explanations of the CSTC Site conveyance systems can be found in Section V of the CSTC Site Development TIR. The western portion of the pre-development basin that has not been improved consists of parking lots and former grandstand and office foundations. These areas currently drain to the CSTC Main Pond. For master plan conditions, post-development Subbasin A-3 was routed through Pond "D" and its control structure, combined with runoff from Subbasin A-2 within the CSTC Main Pond, and routed over the weir just west of Oakesdale Ave SW. Flow over the weir was then combined with runoff from Subbasin A-1 and routed through the CSTC discharge vault to Springbrook Creek. b) Pre-Development Basin 4 and Post-Development Basin B Pre-development Basin 4 will become post-development Basin B under master plan conditions. Under pre-development conditions, Basin 4 was divided into four subbasins for the purpose of routing flows through conveyance features. Subbasin 4-4 drained into Subbasin 4-1 through 12-inch storm Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\I IO2\wp\Drainage Report 01 IV-9 September 2000 • drains south of the former main track and into a swale within the former maid, track. Subbasin 4-1 then_ entered a 12-inch storm drain at the north end of the main track swale, draining the southern half of the former racing track, and flowed to a 36- inch CMP which discharged inside the north end of the former practice track within Subbasin 4-3. Subbasin 4-2 flowed to a 12-inch culvert under the current Oakesdale Ave. SW alignment and discharged to a swale inside the practice track, in Subbasin 4-3. Finally, all four subbasins joined inside the practice track swale (within Subbasin 4-3) and entered an existing 36-inch CMP located under the practice track and protected from backwater events with a cast iron flap gate at the east Boeing property line. From this point, flow traveled through an open channel and to a short 36-inch CMP, which ultimately discharged to Springbrook Creek. Master plan Basin B runoff was routed through enlarged Pond "C" and its control structure. From Pond "C," flow will be conveyed to the existing Practice Track Outfall location at the east property line. c) Pre-Development Basin 5 Pre-development Basin 5 will be merged with post- development Basin B under master plan conditions. Under pre- development conditions, runoff from this basin drained to a meandering ditch running easterly just south of the former practice track, eventually reaching Springbrook Creek. This outfall probably only carried flow from Longacres during larger storm events when water ponded to sufficient depth to overcome topographic features. d) Pre-Development Basin 6 and Post-Development Basin C Pre-development Basin 6 will become post-development Basin C under master plan conditions. Under pre-development conditions, the western half of Basin 6 included no constructed drainage facilities. This area drained southeasterly via sheet flow to the South Marsh Wetland. The western half of master plan Basin C will be drained by a network of catch basins and pipes to proposed Pond "E." Pond "E" will outfall within the buffer of the South Marsh Wetland. Water will travel, as it does now, from the wetland to the east under the alignment of Oakesdale Ave. SW via an Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup CM,Inc. W3X32800\1 I 02\wp\Drainage Report 01.doc IV- 10 September 2000 existing 48-inch corrugated metal pipe. This pipe outfalls to the City of Renton wetlands 12A/12B, which in turn drain 'easterly to Springbrook Creek. Flow was not routed through the 48-inch culvert as no master plan changes to this culvert are planned. 4. Detention Design Tailwater Detention design is based on a future 2-year storage event tailwater influence at Springbrook Creek (high tailwater impacts area addressed in Section V(B). The 2-year tailwater influence was assumed for the following reasons: a) The conveyance event is the critical condition for flow velocities in Springbrook Creek. b) City of Renton policy is for live storage to be above the 2-year elevation in Springbrook Creek, which is elevation 8.60 at the CSTC Delta outlet. c) Since this analysis does not use a model configured to simulate a changing tailwater, a single tailwater had to be selected. The 2-year elevation in Springbrook Creek at the outfall was ( selected as the design tailwater because of potential for non- coincidence with main stem Springbrook Creek peaks and the size of the pond is largely determined by the 2-year events (the lowest frequent event required to meet detention standards). The detention pond analyses are based on peak stage elevations in Springbrook Creek during a simultaneous 2-year, 24-hour, future storage event peak elevation in the creek and a various storm events on-site. The following table summarizes the creek elevations utilized, and is from Table 8-2 in Appendix G: Design Storm Outfall Location at Springbrook Creek Event Basin A Basin B Basin C 2-year, 24-hour 8.6 9.15 10.2 Stage-storage table, stage-discharge tables, peak inflows, peak outflows and corresponding stages for Basins A, B and C are shown in Appendix D.

Summary of Hydrologic Analysis Construction of new combination wetpond/detention ponds and modification of existing facilities as described in this report will result in smaller overall release rates under master plan conditions as compared to pre-development conditions. These release rates are compared below: Design Storm Peak Release Rate (cfs) Event Pre-Developed Post-Developed 2-year, 24-hour 27.7 13.9 10-year, 24-hour 41.2 23.0 100-year, 24-hour 53.5 34.9 More detailed information is included in Appendix D, Table D.1. E. Water Quality System Master plan conditions will create over 1 acre of new impervious surface subject to vehicular use and storage in Basin A, B and C. Since the project site drains to a Class 2 stream within one mile from the project site, special water quality controls have been designed into the landscape at the existing LOP Site and at the existing, downstream CSTC Site. The treatment concept utilizes a two-stage system for water quality control. The first stage consists of parking lot catch basins and wet vaults to contain sediments and provide gravity oil/water separation. The- second stage is a combined wetpond/detention pond with emergent wetland vegetation to improve water quality by absorbing certain constituents in the stormwater stream. Master plan drainage systems will be similar to this existing infrastructure. Detailed calculations for master plan water quality facilities are provided in Appendix F. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\I IO2\wp\Drainage Report 01 IV- 12 September 2000 1. Water Quality Ponds a) Pond "A" Existing Pond "A" in Basin A will be enlarged to provide additional dead storage volume and surface area to accommodate additional tributary area created by construction of the master plan. The enlarged area will be finished in a manner similar to the existing pond and will consist of open water and vegetated sideslopes. Pond "A" will provide 13,700 square feet of design surface and 41,900 cubic feet of dead storage. This is sufficient to serve the master plan area tributary to the pond. b) Pond "C" Existing Pond "C" in Basin B will be enlarged to provide additional dead storage volume and surface area to accommodate additional tributary area created by construction of the master plan. Pond "C" will provide 9,800 square feet of design surface and 23,300 cubic feet of dead storage. This is sufficient to serve the master plan area tributary to the pond. c) Pond "D" Pond "D" was designed as a combined wetpond/detention pond in accordance with the KCSWDM as adopted by the City of Renton. It is landscaped in the same manner as the CSTC Main Pond. The vegetation within Pond "D" consists of a diverse range of palustrine (freshwater) wetland plant communities. The plant communities are typical of those that occur in the Green River Valley and the Puget Sound Lowlands. These wetland planting zones were also established successfully in the CSTC wetlands that this pond is connected with. Pond "D" was designed to provide water quality treatment for runoff from the master plan site west of Oakesdale Ave. SW and north of the SW 27th St. corridor. The wetpond volume and surface area exceed that required by at least a factor of 1.5 to compensate for not providing biofiltration. Pond "D" provides 78,000 square feet of design surface and 264,000 cubic feet of dead storage. This is sufficient to serve the master plan area tributary.to the pond. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\I 102\wp\Drainage Report 01 IV- 13 September 2000 d) Pond,"E" Pond "E" is designed as a combined wetpond/detention pond. It is designed to provide water quality treatment for runoff from the master plan site south of the SW 27th St. corridor. The wetpond volume and surface area exceed that required by at least a factor of 1.5 to compensate for not providing biofiltration. Pond "E" will provide 20,900 square feet of design surface and 53,200 cubic feet of dead storage. This is sufficient to serve the master plan area tributary to the pond. 2. Water Quality Storm Event According to the most recent KCSWDM, the water quality storm event represents runoff from 95 percent of the annual average runoff volume. The response of Pond "D" and the CSTC Main Pond system to the water quality event was therefore selected as an important benchmark for design of the pond landscape and wetland plantings. Appendix F of Drainage Report - Surface Water Management Project included information on the system response to a water quality design storm event for master plan conditions. The results indicated that the system will rise less than 5 inches under master plan conditions during a water quality storm event. This is within the 6-inch tolerance dictated by the landscape design. 3. Water Quality Data Appendix E contains water quality data derived from samples taken from Springbrook Creek and the site prior to any Boeing development. This information shows the relatively poor water quality of the creek and some on-site locations. The on-site wetpond/detention system will improve the quality of runoff leaving the project site and will help improve the water quality of Springbrook Creek. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup CMI.Inc. W3X32800\1102\wp\Drainage Report OI.doc IV-14 September 2000 V CONVEYANCE SYSTEM ANALYSIS AND DESIGN A. Proposed (Master Plan) Conveyance System Overview The master plan storm drainage system will collect runoff from buildings, paved and parking areas, roadways, and landscape, and convey it to one of several treatment facilities. This may be accomplished in a system similar to those at existing Boeing developments at this property. There are three master plan drainage basins on the property. Basin A is the largest and includes existing Ponds "A," "D," "N," the CSTC Main Pond and the Delta Area. Flow treated in these ponds is conveyed through existing systems to the CSTC Site Outfall. Undeveloped portions of this basin will be collected and conveyed in a system similar to those at existing Boeing developments at this property. Proposed outfalls from several areas of this basin will be located at the proposed channel draining from SW 27th St. to Pond "D." Basin B is the smallest basin and includes Pond "C." A portion of this basin is already developed and conveys runoff southerly to Pond "C." The remainder of Basin B will be conveyed via conventional catch basin and pipe networks,to Pond "C" under master plan conditions. Basin C is located at the southern end of the property, south of the SW 27th St. corridor, and has not been developed. Proposed conveyance facilities will include conventional catch basin and pipe networks that will drain to proposed Pond "E." Pond "E" will outfall via pipeline to the buffer of the South Marsh Wetland. B. Conveyance System Analysis and Design: The proposed conveyance system for the project site is designed to conform with Chapter 4 of the KCSWDM, which provides approved methods and criteria for hydraulic analysis' and design of storm drainage facilities. The detailed analyses of all master plan conveyance systems will be completed for the final drainage report, but are not included herein because it is not a requirement of conceptual drainage plans. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 V- 1 September 2000 1. Pipe System Design A portion of drainage pipelines serving the master plan parking lot in post-developed Basin C were preliminarily sized using the Rational Method for Conveyance System Analysis and Sizing — Uniform Flow Condition table in Appendix G. This table is based upon Figure 4.3.3C of the KCSWDM. To simplify the analysis, only the 100-year 24-hour storm event was used. While this.choice of storm events may result in oversized pipes, it results in a conservatively sized system that will perform its intended function. Final design should base initial pipe size on the 25-year 24-hour event.,as described within the KCSWDM. Other master plan pipelines were not evaluated as part of this conceptual drainage plan, but are assumed to be similar to systems constructed as part of previous Boeing projects at this property. 2. Open Channel Design Open channels could be used to convey runoff from the southern portion of Basin A to Pond "D." These channels would be interrupted by master plan on-site road crossings, and could be connected by culverts at those locations. The open channels were preliminarily designed as vegetation-lined, trapezoidal cross sections in accordance .with KCSWDM Section 4.3.7 — Open Channels. The analysis assumed a Manning's "n" value of 0.10, which is equivalent to a natural channel with very weedy reaches, deep pools, or floodways with heavy stands of timber and underbrush. Based on conveying the entire subbasin 25-year 24-hour peak design flow of 40 cfs, the channel cross section is 15 feet wide with 1:10 sideslopes, flowing at about 2.8 feet deep. The design flow rate at each channel segment must be refined during final design. Also, the design of these channel sections should be carefully evaluated during final design of the master plan facilities, particularly with regard to backwater effects on upstream facilities. 3. Culvert Design The master plan includes culverts that could connect the south-to- north flowing open channels conveying runoff from the southern portion of Basin A to Pond "D." These culverts would be located at master plan on-site road crossings. The culverts were preliminarily,designed to be box culverts installed with below- grade inverts and backfilled with gravel. The analysis assumed a Manning's "n" value of 0.05, which is equivalent to a constructed channel with jagged and irregular rock lining. Based on conveying Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 V-2 September 2000 the 25-year 24-hour peak design flow of 40 cfs, the box culvert is 8.feet wide, flowing at about 2.6 feet deep. During final design of master plan facilities, vertical constraints resulting from proposed roadways, topography and existing and proposed utilities must be evaluated at culvert locations. 4: Backwater Analysis a) Basin A The existing drainage pipelines serving the BCAG Headquarters facility were previously analyzed using King _ County's Backwater Analysis Program as part of the BCAG Headquarter Site Development Project. Those analyses were based on tailwater elevations (i.e. pond peak stage elevations) at Pond "D" for approximate master plan conditions. The elevations were 11.80 and 12.56 for 25- and 100-year 24-hour events, respectively, and they were based on simultaneous peak stages in Springbrook Creek for the same storm event. Development of the master plan will increase the peak runoff rates contributing to Pond "D" due to increased impervious surfaces and improved conveyance systems. As detailed in Appendix G, the master plan peak stages in Pond "D" will be 11.32 and 12.19 for 25- and 100-year 24-hour events, respectively, based on conveyance (not detention). These elevations will form the tailwater elevations for backwater analyses for those systems discharging to Pond "D." These elevations are lower than those described in the previous paragraph. Previous backwater analyses of the BCAG Headquarters systems were completed with higher tailwater elevations (as described in Section V of Drainage Report, Surface Water Management Project, February 1999), but they demonstrated that the existing systems met the criteria for freeboard and overtopping. Therefore, by inspection, the existing systems will continue to perform adequately under master plan conditions. The previous analyses at the higher tailwater elevations are included in Appendix G for reference. b) Basin B The existing drainage pipelines serving the northern portion of Basin B were previously analyzed using King County's Backwater Analysis Program as part of the Family Center Site Development Project. The analyses were based on the Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Ino. W3X32800\1102\wp\Drainage Report 01 V-3 September 2000 100-year 24-hour tailwater elevation of 13.13 at Pond "C" for conditions at that time. Elevation 13.13 is the 100-year peak stage elevation in Pond "C" assuming that flow leaves the pond only over the emergency spillway (the spillway is at elevation 13.00). This assumption is a good approximation of conditions expected during a 100-year, future storage event on Springbrook Creek, when the creek rises to elevation 12.85. This scenario demonstrated that the system met the 25-year 24- hour event requirements as well, therefore, the 25-year event was not modeled. The master plan proposes to enlarge Pond "C" and this will offset the increase in peak runoff contributing to the pond after master plan development is completed. Based on the same assumptions described above, the existing peak stage in enlarged Pond "C" can be matched under master plan conditions provided that the ,emergency overflow spillway length is sufficient and/or the spillway elevation is reduced to about elevation 12.85. Each of these changes is reasonable, therefore, by inspection, the existing systems will continue to perform adequately under master plan 'conditions. Alternatively, detailed analyses can be completed during final design of master plan facilities. c) Basin C A portion of drainage pipelines serving the master plan parking lot in post-developed Basin C were analyzed using King County Department of Natural Resources Backwater Analysis Program Version 5.30f. The tailwater elevation used for this analysis was a function of the simultaneous, 100-year, future flow storage, peak stage elevation in Springbrook Creek at the upstream side of the SW 27th St. Bridge. The creek elevation during this event is 13.0 per Table 8-2 in the ESGRWP, by R.W. Beck, dated December 1996 (refer to Appendix G for more detail). It is assumed that when the creek reaches elevation 13.0, some inundation of the adjacent, off-site City of Renton wetlands will occur. It is further assumed that this water will cause backwatering in the on-site South Marsh Wetland, in Basin C. While the extent of this backwater is unknown, backwater analysis in Basin C is based on the assumption that water in the South Marsh Wetland will reach elevation 14.5 during the 100-year event. Pond "E" design is based on this tailwater, and it reaches a peak stage of 16.55 during a simultaneous 100-year 24-hour event. Therefore, Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc. W3X32800\1102\wp\Drainage Report 01 V-4 September 2000 elevation 16.55 was used as the backwater analysis tailwater for the Basin C storm drainage network. Further investigation into actual peak stage in the South Marsh Wetland may be justified if, during final design of master plan facilities, it becomes apparent that the peak stage significantly constrains grading and drainage design. d) Springbrook Creek Peak Stages The backwater analyses are based on peak stage elevations in Springbrook Creek during a simultaneous 25- and 100-year 24-hour, future storage events in the creek. The following table summarizes the elevations utilized, and is from Table 8-2 in Appendix G: Outfall Springbrook 25-Year 100-Year Location Creek Peak Peak Location Stage Stage SW 16th St. 8.0 12.7 Basin A (interpolated valuue) 10.0* 12.8* Confluence of Rolling Hills Creek 10.0 12.8 Basin B (interpolated value) 10.6 12.85 Confluence of SW 23rd St. Creek 11.2 12.9 Basin C SW 27th u/s 11.7 13.0 Note: Interpolated value is conservative, but matches previous analyses at this property. 5. System Materials Runoff will generally be collected in precast concrete catch basins. Type 1 P catch basins may be used throughout parking areas while smaller catch basins may be used in other areas. City of Renton standard manholes and Type 2 catch basins may be utilized at system junctions. Pipes may be constructed of PVC, reinforced concrete, ductile iron, HDPE, or unreinforced concrete, depending upon size, location and loading. Perforated underdrain pipes may be placed along walkways, roadways or other areas where water is to be intercepted. Open channels may be constructed through the center of the property in a south-to-north alignment to convey runoff towards existing Pond "D." Open channels may be Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Chill,Inc.

Based on preliminary calculations, it is likely that a channel cross-section can be developed that will allow the use of bioengineered stabilization. Final design of the channels will determine what lining system is required to protect soils from erosion. The open channels will be connected by segments of culvert at road crossings. These culverts may be pipe, arch or box culverts and constructed of concrete or corrugated metal. Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Chdl,Inc. W3X32800\I l02\wp\EXH B-Drainage Report 01.doc.doc V-6 September 2000 • VI FLOODPLAIN AND GROUNDWATER INFORMATION A. Floodplain Conditions Federal Emergency Management Agency ("FEMA") Flood Insurance Rate Map Panel 53033C0978F and Flood Profile 45P for Springbrook Creek indicate the 100-year floodplain elevation in the vicinity of this project. The City of Renton East Site Green River Watershed Plan ("ESGRWP") Table 7-3 indicates that the FEMA 100-year floodplain elevation varies from 15.8 to 16.4 feet based on National Geodetic Vertical Datum (NGVD) of 1929. The flood elevation generally rises to the south (upstream on Springbrook Creek). FEMA flood elevations shall be used to establish building finished floor elevations to comply with flood insurance requirements. Compensatory storage requirements are specified in City of Renton Ordinance No. 4835, "Compensatory Storage." The ordinance prohibits the reduction of effective base flood storage volume based on the higher of the City hydrologic and hydraulic model results for the 100-year future land use conveyance and storage events in Springbrook Creek. Furthermore, the ordinance specifies that only when the FEMA-defined 100-year flood zone is lower than the City model results would the FEMA elevations be used. That is not the case for Springbrook Creek adjacent to this property, therefore, the City's model results are to be used. Review of the City model indicates the following peak elevations in Springbrook Creek: Springbrook Creek Location Peak Stage SW 16th St. 13.0 (1) Confluence of Rolling Hills Creek 13.1 (1) Confluence of SW 231d St. Channel 13.3 (1) SW 27th u/s 15.6 (2) Notes (1) 100-year future flow storage.

Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil. Inc. W3X32800\1102\wp\Drainage Report 01 VI-1 September 2000 Review of pre-development topography along the eastern property line where it abuts the creek indicates that peak stage in the creek could not inundate the property at the above elevations. This is shown in Figure A.5 in Appendix A. Furthermore, all pre-developed creek outfall pipes were protected by mechanical flap gates, which also prevented inundation of the property. An area of about 7,500 square feet at the south end of the former practice track may be subject to flooding up to 2 feet deep, provided that topography between this location and the creek does not exceed elevation 13.3 (Springbrook Creek elevation at river cross section closest to practice track). The potential storage at issue is about 0.33 acre feet, and may not be significant. If it is deemed relevant, the substation proposed near this location could be designed to avoid filling those areas below elevation 13.3, thereby maintaining base flood storage volume. A sketch of this location and the area subject to flooding is included in Appendix A, Figure A.6. At the South Marsh Wetland, pre-developed topography was such that it may have been subject to inundation by the creek up to the limit of its buffer. Under master plan conditions, the South Marsh Wetland and its associated buffer will not be filled, therefore, no effective base flood storage will be eliminated. A sketch of this location and the area subject to flooding is included in Appendix A,Figure A.7. The FEMA map and flood profiles of the Black River and Springbrook Creek are included in Appendix A, Figures A.1, A.2, A.3 and A.4. For the purpose of backwater analysis of the proposed conveyance system, Springbrook Creek elevations (forming site tailwater) are based on the ESGRWP rather than the FEMA flood profiles. Table 7-3 of the ESGRWP draft plans is included in Appendix A. B. Groundwater Influence Numerous geotechnical reports have been completed at this site. These reports provide specific information about site groundwater, which is generally very shallow. It is recommended that additional geotechnical investigation be completed to support master plan design when specific work is identified in the future. Refer to Section ll(B)11 for a listing of previous geotechnical reports. Geotechnical reports completed April 23, 1998 and January 22, 1999, by GeoEngineers, Inc. provide specific information about the groundwater at the Surface Water Management Project project site. Groundwater • conditions were evaluated by measuring the water level in monitoring wells installed at depths of 8.5 to 9 feet and at depths of 16.5 feet. Groundwater levels were measured regularly between April 9, 1998 and Development Agreement Project-Drainage Report for Conceptual Drainage Plan Sverdrup Civil, Inc.

Temporary Erosion/Sedimentation Control.(TESC) Plan The TESC plan must be designed to comply with Chapter 5 of the King County Surface Water Design Manual (KCSWDM) as adopted by the City of Renton. A detail sheet in the TESC plans must list the standard City of Renton Erosion Control Notes (from the Drafting Standards) as well as applicable requirements from the KCSWDM Reference - 9 Standard Plan Notes. Since the notes are based on two independent sources and often have the same intent, they can be organized to match the recommended construction sequence as shown at the end of Reference - 9. B. NPDES Requirements Since master plan development will disturb more than five acres of total area, the applicant will be required to file a Notice of Intent (NOI) for coverage of this project under the Baseline General Permit for Stormwater. Additionally, the applicant will need to prepare a Storm Water Pollution Prevention Plan to fulfill the requirements of the Federal Water Pollution Control Act (33 USC 307) and the State of Washington Water Pollution Control Law (Chapter 90.48 RCW), and regulations that address the control of storm water discharges (40 CFR, Parts 122, 123, 124; WAC 173-201A, 216, 220 and 226). This Plan is to be kept at the construction site project office. • Development Agreement Project-Drainage Report for Conceptual Drainage Report Sverdrup Civil, Inc.

Develop hydrographs for uncontrolled flows generated in subbasins 4-1, 4-2, 4-3 and 4-4 . Route hydrographs through predevelopment surface features and determine (routed) predevelopment release rates to Springbrook Creek. PROCEDURE: Basin 4 is a 84 . 52 Acre basin, consisting of four sub asins . SUBBASINS 4-1 and 4-4 Reference attached hydrologic calculations for these asins, of area 16 . 49 Acres and 45 .46 Acres, respectively. These hydrographs are routed through the main racetrack (before they are added to hydrgraphs from basins 4-2 and 4-3) . SUBBASINS 4-2 and 4-3 Reference attached hydrologic calculations for these asins, of area 13 .24 Acres and 9 .33 Acres, respectively These hydrographs are added to the routed hydrographs of asins 4-1 and 4-4, then routed through existing surface featu es before leaving the property.

Omit routing of this hydrograph through surface features and determine resultant release rates to Springbrook Creek. BACKGROUND Subbasin limits and tributary areas of the masterplan drainage basins are dramatically different then they were at the predevelopment stage due to proposed topographical changes . Because bypasses are allowed by KCSWDM Core Requirement #3 (i .e. the sum of the masterplan release rates from the 4 individual discharge locations may be compared to release rates at a "point of compliance" downsteam of the Delta discharge in Springbrook Creek) it would theoretically be permissible to allow release rates from 14 . 07 Acre postdeveloped Basin B to be as high as the release rates from 84 . 52 Acre predeveloped Basin 4 . If such an approach were implemented, then it would be feasible to omit detention at masterplan basin B, as ample detention storage is provided in ,Basin A to compensate. However, Boeing storm drainage analyses have historically acknowledged a release rate criteria imposed on a per-outlet basis . If Boeing continues to programmatically develop this property, or if the basin without detention were to be sold in the future, or if the 1998 KCSWDM were adopted, then one might argue that the drainage system is not in compliance with detention requirements . Therefore, the maximum permissible masterplan postdevelopment release rates from a given masterplan basin will be the smaller of the release rates from the following basins : 1 . True predevelopment baseline basin 4, 84 . 52 acres, per : section [B4. 0] . 2 . A modified pre-development drainage basin with the basin area truncated to match the plan limits & 14 . 07 acre of the masterplan Basin B.

For these modified basins, routing of the uncontrolled flow through predevelopment ponds, culverts, etc . will not be completed. The raw uncontrolled modified hydrographs will provide the maximum release rates which will be the basis for detention Pond "C" design. PROCEDURE: Basin 4' is a 14 . 07 Acre basin.

This subbasin discharges easterly via a 48-inch CMP under Oakesdale Ave. SW, through the adjacent wetlands and eventually to Springbrook Creek at SW 27th Street (Outlet #5) . PROCEDURE: • Basin Description / Flow Path Description: This '19 . 73 acre western subbasin to Basin 6 represents the basin limits .for flow entering the existing wetland. The limits of this basin are similar to the limits of post- development masterplan basin C-1, except that the northern subbasin boundary will be revised due to a master plan roadway. Runoff generally flows southeasterly from this subbasin, until about elevation' 14 . 0 , where flow enters the wetland buffer area. The elevation of this western half of Subbasin 6W varies from elevation 25 . 0 to 15 . 0 . Assuming the peak stage of the wetland is no greater than 14 . 5 (see Section. [C6 . 0] in Appendix D for discussion of tailwater influence) , flow from this basin is independent of peak stage in the wetland. • Time of Concentration: Tc is calculated as 34 . 6 minutes . See attached summary and plot. • Land Usage / Curve Number: CN is estimated as 87 . 31 and 98 . 00 for pervious and impervious areas, respectively. • Hvdrograph summaries .

The limits of this basin are similar to the limits of predevelopment basin 6W due to proposed topography. Runoff will be collected from the parking lots, building roofs, landscaped areas, and remaining areas of Basin C-1 and routed to proposed wetpond/detention Pond "E. " Peak runoff from this subbasin will be used to size wetpond/detention Pond "E" for masterplan subbasin C-1 . • Time of Concentration: Tc is calculated as 21 . 3 minutes .

Determine and check peak pond stages and peak flows at each pond, for the 2-Yr, 10-Yr, and 100Yr- 24Hr Storm Events . Perform routing under the tailwater influence of the 2Yr-24Hr flood stage of Springbrook Creek, which is elevation 8-. 60 at Outfall No. 2 . REFERENCES 1 . KCSWDM, 1990 ASSUMPTIONS AND NOTES • The post development revised master plan subbasin hydrographs, for Basins A-1, A-2 , and A-.3 are used for this exercise. These subbasins now include' the additional masterplan parking required to serve buildings enlarged beyond original master plan size. Basin A-3 now excludes tributary area from south of SW 27`h Street. - • The flood stage `at Springbrook Creek during the 2Yr, 25 Yr, and 100Yr-24hr storm events is 7 . 80,- 9 . 00, and 12 . 75 per City of Renton (Table 8-2 & 7-3 for 4th creek improvement alternate) . However, to. match past Sverdrup storm drainage calculations, the assumed flood stages at Springbrook Creek at Outfall No . 2 during the 2Yr, 25 Yr, and 100Yr-24hr storm events will be 8 . 60 , 10 . 00 , and 12 . 80 , respectively. • KCSWDM requires live storage to take place above the tailwater for the 2-Yr-24Hr event. Therefore detention capacity will be checked by routing the 2Yr, 10 Yr, and 100Yr-24hr storm events through Pond D, CSTC Pond and Delta Pond assuming a Springbrook flood elevation of 8 . 60 for each of these storm events . The resultant peak outflows from the. 2Yr, 25 Yr, and 100Yr-24hr storm events will be compared with pre-development flows to ensure compliance with detention requirements .

See Section [A8 . 0] in Appendix G for these calculations . • While routing through any given structure or device, the downstream tailwater is assumed to be constant and equal to the peak stage achieved in the downstream pond/creek during the storm event. • The multiple pond routing exercise is an iterative procedure for each given storm event . As routing occurs from pond to pond, the assumed tailwater must be the same as the peak stage calculated for that pond. During this iterative procedure, as tailwaters change, the stage-discharge relationships of the flow control structures / weirs change and must be updated for each specific tailwater assumed. The goal of the iterative procedure is to route through the three ponds and structures to obtain upstream and downstream pond/creek stages/tailwater elevations that agree within a reasonable tolerance. PROCEDURE Reference the following calculation sets for Basin A detention routing exercises . The control structures for .the ponds in Basin A are existing, and sketches- of these structures are included on the followng pages . All routing was performed using the 2Yr flood stage of.

Wetponds or Wetvault • Wetponds and Wetvaults contain a permanent pool of water depending on the frequency and quantity of inflow,and (for Wetponds)the rate of permeability of the underlying soil. The Wetponds and Wetvaults fill with the initial onset of frequent storms such that the major portion of the volume of runoff is treated. The principal mechanism of treatment is settlement due to establishment of calm conditions. In Wetponds treatment Is enhanced by the mechanisms of biofiiltration and biologic activity. The size of the Wetpond or Wetvauits shall be determined as follows: (1) The design water surface area In the Wetpond or Wetvault shall be a minimum of one percent of the Impervious surface area In the drainage sub-basin contributing to the facility. (2) The design volume of the Wetpond or•Wetvautt shall be a minimum of the total volume of runoff(see Chapter 3: Hydrologic Analysis)from the tributary sub-basin proposed developed conditions using a water quality design storm event having a total precipitation (Pt-wq),where Pt-wq is one-third of the two-year, 24-hour total precipitation (P2/3, P2 Is obtained from Figure 3.5.1 C). This water quality design storm event approximates the runoff from the mean annual storm event. Water Quality Swale Water Quality Swages treat runoff by acting as filters for the runoff from frequent storms. The principal mechanism of treatment is slowing of particles to which pollutants are attached allowing them to settle out. This treatment is enhanced by the'taking-up"of the dissolved fraction of pollutants by the vegetation. • 1 N L iEL)` of MMCIN6 IBO77/ A- Ql o s&d*L.E AO) 'J rvit u1 THE' GI rY op RE W; h/IL.C. ma-ow pis USE OF bill) OVV7ZS I E-Eb w ET vA-1A-r OF ki r Pt"A ThE S ILiIQ6- ReRvikemehi i is As Fwuu‘a$ VERol fed wrrPoi4A f WET vlimr VcL_iJME• = I.

The City of Renton is currently requiring the use of the 1990 King County Surface Water Design Manual. One exception is that for added impervious over 1 acre the KCSWDM requires a biofiltration swale and a wetpond. The City of Renton has modified this requirement and accepts a wetpond with a surface area and volume 1.5 times that required by the KCSWDM in lieu of a biofiltration swale. The City is currently reviewing the 1998 King County Surface Water Design Manual to determine which parts will be adopted. Alan thought that it would be another year before the City makes a decision about what to adopt. However,the City does currently allow and accept the use of the 1998 Manual,but does not require it.

The Wetponds and Wetvaults fill with the initial onset of frequent storms such that the major portion of the volume of runoff Is treated. The principal mechanism of treatment is settlement due to establishment of calm conditions. In Wetponds treatment is enhanced by the mechanisms of biofiltration and biologic activity. The size of the Wetpond or Wetvaults shalt be determined as follows: (1) The design water surface area in the Wetpond or Wetvault shall be a minimum of one percent of the Impervious surface area In the drainage sub-basin contributing to the facility. (2) The design volume of the Wetpond or•Wetvault shall be a minimum of the total volume of runoff(see Chapter 3: Hydrologic Analysis)from the tributary sub-basin proposed developed conditions using a water quality design storm event having a total precipitation (Pt-wq), where Pt-wq is one-third of the two-year, 24-hour total precipitation (P2/3, P2 is obtained from Figure 3.5.1C). This water quality design storm event approximates the runoff from the mean annual storm event. Water Quality Swale Water Quality Swabs treat runoff by acting as filters for the runoff from frequent storms. The principal mechanism of treatment is slowing of particles to which pollutants are attached allowing them to settle out. This treatment is enhanced by the "taking-up"of the dissolved fraction of pollutants by the vegetation.

Wetponds or Wetvault Wetponds and Wetvautts contain a permanent pool of water depending on the frequency and quantity of inflow,and (for Wetponds) the rate of permeability of the underlying soil. The Wetponds and Wetvautts fill with the initial onset of frequent storms such that the major portion of the volume of runoff Is treated. The principal mechanism of treatment Is settlement due to establishment of calm conditions. In Wetponds treatment Is enhanced by the mechanisms of biofittration and biologic activity. • The size of the Wetpond or Wetvautts shall be determined as follows: (1) The design water surface area in the Wetpond or Wetvault shall be a minimum of one percent of the Impervious surface area In the drainage sub-basin contributing to the facility. (2) The design volume of the Wetpond or•Wetvault shall be a minimum of the total volume of runoff(see Chapter 3: Hydrologic Analysis)from the tributary sub-basin proposed developed conditions using a water quality design storm event having a total precipitation (Pt-wq),where Pt-wq Is one-third of the two-year, 24-hour total precipitation (P2/3, P2 is obtained from Figure 3.5.1 C). This water quality design storm event approximates the runoff from the mean annual storm event Water Quality Swede Water Quality Swales treat runoff by acting as filters for the runoff from frequent storms. The principal mechanism of treatment Is slowing of particles to which pollutants are attached allowing them to settle out This treatment is enhanced by the'taidng-up' of the dissolved fraction of pollutants by the vegetation. • 1 N LIEU- oF- MA/INNN&4O77/ i4- QI d s&.1*L.E /t1J.1) A- wETV4vL.t THE 1 TY OF /2ET,,t71//a WlL kL4-vw 7f1E use- OF *il) OvelLs 1 E4 w ET- VA I)(.r vF MET- P"N1 me sif,N6- 12&6hiILEmeo or is As fiudak.2s vial trial-mai (der- v#iit.r vaLth4.6- = 1.

A A8.2.E CHECK STORM VOLUME VS. VOLUME OF CLOSED DEPRESSION In addition to the routing analysis described above, a volumetric check of the on-site storage volume was performed: • The 100Yr-24Hr peak flood stage in Springbrook Creek, elevation 12=. 80, will prevent discharge from Basin A until the peak stage in . the Delta Pond reaches elevation 12 . 80 . Assuming the pre-storm water surface elevations of Pond D, CSTC Pond, and DeltaPond is equal to the design water surface elevation when the storm begins, determine the peak stage to store the entire storm volume among all three ponds . • Reference attached stage/storage interpolation and summary spreadsheet, with schematic pond profile indicating the entire 100r-24Hr storm will be stored at a common pond stage of 11 .35 . - The 100-year 24-hour Basin A hydrographs are included below: W3X32800/1102/ENGR/BASINA&3/PARCALCBSNA[8.2)(100Yr@12.8).DOC Page 7 Of 9 09/27/00 12:07 PM I]] Sverdrup JOB NO BY BOEING LONGACRES OFFICE PARK SHEET W3 X3 2 8 0 0 PAR DEVELOPMENT AGREEMENT: SITE STORM DRAINAGE 8 DATE CHK'D REVISED MASTERPLAN: BASIN A OF 0 9/0 0 CONVEYANCE ANALYSIS: 2® • ROUTE BASIN A WORKS4.EXE PIQM File,_MINIM,'Hydrograpb Storageµ: :' Discharge •, I+Paol ,Proja:.S1iya' • Basin"ID: P281100: Descr.ptian., :j 9:<f��[ 5B11 i�ICS5E�l5IS� ::"_41r11&::'Y ' ;'Rain • ?lathed '• Peru. ,i�' M;'. 23.300 �`• ' a •.act Inperu 1.580.

While each of these analyses result in somewhat different on-site peak stage elevations, it seems reasonable and more conservative .to utilize the greater peak stage elevations resulting from the routing exercise as tailwater elevations for the purpose of checking future, upstream conveyance systems (i .e. : future on-site parking lot pipe systems) . • W3X32800/1102/ENGR/BASINA&3/PARCALCBSNA[8.2](100Yr@12.8).DOC Page 9 of 9 09/27/00 12:07 PM i% Boeing Commercial Airplane Group Surface Water Management: Development Agreement Project -- \, Pond "D" Outlet Structure Storm Event: 100Yr-24Hr with 100Yr Tailwater at•Springbrook Creek=El. 12.80 CSTC Pond Tailwater Elev.= 11.45 Stage Inlet Pipe Telescoping Risers Weir Outlet Pipes Dischargew (ft) (cfs) (cfs) (cfs) (cfs) (cfs) 10.60 0.00 0.00 0.00 0.00 0.00 10.70 0.00 0.00 0.00 0.00 0.00 10.80 0.00 0.00 0.00 0.00 0.00 10.90 0.00 0.00 0.00 0.00 0.00 11.10 0.00 0.00 0.00 0.00 0.00 11.20 0.00 0.00 0.00 0.00 0.00 11.30 0.00 0.00 0.00 0.00 0.00 11.40 0.00 0.00 0.00 0.00 0.00 .................................. ....................... .. . ... ...... 11.60 36.80 26.37 . 40.63 18.72 18.72 11.70 47.50 34.05 52.70 • 24.16 24.16 11.80 56.21 40.28 63.69 . 28.59 28.59 11.90 63.73 45.68 74.27 32.42 32.42 12.20 82.28 58.97 105.61 41.85 41.85 12.40 92.60 66.37 126.94 47.10 47.10 12.60 101.88 73.02 148.89 51.82 51.82 12.80 110.39 79.12 171.57 56.15 56.15 iiiiiiiiiiil!tootimiligibl .m..................... 13.20 125.68 90.08 219.25 63.93 63.93 13.40 132.67 95.09 244.28 67.48 67.48 13.60'• 139.31 99.84 270.11 70.86 • 70.86 13.80 145.64 104.38 296.73 74.08 74.08 :;,<: s#><>%«; '<»>> :;< >> : �III'»II> < 1'17l' > >><' lifiii iiirtA "::>:::<: <�:4�At�::»:<:»:>;>:€:>:::<:>::::>::1�a:t.,...1..........................'I f�t��............................32?�,:..8.........................�`7�.9................. .................7''�.�17................. 14.20 157.55 112.92 352.37 80.13 80.13 14.40 163.18 116.95 381.37 83.00 83.00 Notes (1) The controlling flow is the minimum of the following flows: 1) Inlet Pipe Flow; 2)Telescoping Risers+Weir FI and 3)Outlet Pipe Flow.

Refer to attached FlowMaster Version 6 . 0 output. The channel has a proposed slope of 0 . 15% over its 1, 600-foot length from SW 27th St. to the south end of Pond "D. " A Manning' s "n" of 0 . 10 was used (value from KCSWDM Table 4 .3 .7B) , which is equivalent to a "natural channel with very weedy reaches, deep pools, or floodways with heavy stands of timber and underbrush. " The estimated flow depth for the 25-year 24- hour storm event is 2 . 8 feet. Note: The design of these channel sections should be carefully evaluated during final design of the master plan facilities, particularly with regard to backwater effects on upstream facilities . • Box Culvert Design: A typical 8-foot wide box culvert with buried invert and gravel backfill was analyzed. Refer to attached FlowMaster Version 6 . 0 output. The box culverts have a proposed slope of 0 . 15% to match adjacent channel bed slope. A Manning' s "n" of 0 . 04 was used (value from KCSWDM Table 4 .3 .7B) , which is equivalent to a "jagged and irregular rock-lined constructed channel . " The estimated flow depth for the 25-year 24-hour storm event is 2 . 6 feet . Note: During final design of master . plan facilities, vertical constraints resulting from proposed roadways, topography and existing and proposed utilities must be evaluated at culvert locations .

SCOPE Complete preliminary backwater analysis of Basin "C" storm drainage system under master plan conditions for a 100-year 24- hour storm event. The preliminary uniform flow analysis for this system is attached at the end of the analysis . REFERENCES • King County, Washington, Surface Water Design Manual (KCSWDM) and King County Direct Step Backwater Program, Version 5.30f. • Preliminary Uniform Flow Analysis, 8/29/00, attached. ASSUMPTIONS • The pipe network ultimately required to serve this basin has not been designed beyond a conceptual level . Final design is not within the scope of this project. Therefore, the hydrologic modeling for the area draining to the pipeline system is approximate and has not undergone detailed design. The uniform flow analysis prepared to support this backwater analysis was prepared for the 100-year 24-hour event only, because this analysis will indicate that even the 100-year event will meet the freeboard requirements of the 25-year event. • The tailwater elevation utilized in this analysis is the peak stage elevation in Pond "E" during the 100-year 24-hour storm event, including influence from the 100-year peak stage elevation in Springbrook Creek. Analysis of Pond "E" included the effects of downstream water surface elevations in the South Marsh (Wetland "M" ) , and therefore, no backwater analysis is required from the wetland upstream to Pond "E" . • A single upstream velocity is assumed to be 0 . 1 f/s . This is considered to be a conservatively low velocity that adds very little energy to the system. \\CIVSEAADM1\DATA1\JOB\W3X32800\1102\Engr\BasinC&6\jjscalcOl[8.0] .doc piSverdrup JOB No BY BOEING LONGACRES OFFICE PARK SHEET W3X3 2 8 0 0 JJS DEVELOPMENT AGREEMENT PROJECT 2 DATE CHK'D OF STORM DRAINAGE SYSTEM DESIGN 8/2 8/0 0 W. BASIN "C" BACKWATER ANALYSIS " PROCEDURE This is a preliminary analysis of the main drainage piping system proposed to serve Basin "C" under master plan conditions . 1. Create BW program pipe input file. Data in this table are from the preliminary plan drawing included in the uniform flow analysis calculations (attached) . The input file is as follows : Pipe Pipe Pipe Pipe Outlet Inlet Inlet Overflow Bend Struct No. Length Dia. Type. Elev Elev Type Elev Angle Width 1 500 27 1 12.59 14.59 4 21.0 90 4 2 50 24 1 14.84 15.04 4 21.0 0 4 3 205 24 1 15.04 15.86 4 21.0 0 4 4 375 21 1 16.11 17.61 .4 21.5 90 4 5 285 15 1 18.11 19.25 4 "Q" Ratio is the ratio of tributary flow at the junction to the main upstream flow at the junction. Due to the fact that some of the preliminary subcatchment areas in this basin have a significantly higher time of concentration than other areas, the uniform flow analysis was manually adjusted to prevent the appearance of decreasing flows in a downstream direction. The time of concentration of the prior subcatchment area was used when such a situation was encountered. The minimum time of concentration of contributing catchment area was used at, each node. However, this results in conservation of matter discrepancies at the nodes (i . e. : the sum of inflow does not equal the outflow at a given junction) . Therefore, the Q Ratio was adjusted such that pipe flow in the backwater analysis is the same as the flow determined by the uniform flow analysis . Refer to Figure 1 for a graphic description of this adjustment. 25-Year 100-Year Ratio Event(trib/main) Event(trib/main) 1 n/a 5.02/11.45=0.415 2 n/a (4.74+(-3.53))/10.90=0.111 3 n/a (3.22+0.73)/6.95=0.568 4 n/a (1.87+2.99)/2.09=2.325 This input file is saved as C_100yr.bwp in the project directory. \\CIVSEAADM1\DATA1\JOB\W3X32800\1102\Engr\BasinC&6\jjscalc0l[8.0] .doc El Sverdrup JOB NO BY BOEING LONGACRES OFFICE PARK SHEET W3 X3 2 8 0 0 JJS' DEVELOPMENT AGREEMENT PROJECT 3 DATE CHK'D STORM DRAINAGE SYSTEM DESIGN OF 8/2 8/0 0 BASIN "C" BACKWATER ANALYSIS 1 -7 2 .

Where; 17 . 13 cfs is the 100-yr peak flow to Pond "E" as shown in the preliminary Rational Method Uniform Flow Analysis . 3 . The analysis output file was formatted in Word and modified to eliminate intermediate flow rates in the pipes to reduce analysis output length. Results of the preliminary backwater analysis indicate that during the 100-year event, system freeboard varies from about 1 . 5 to 2 . 6 feet. This meets the freeboard requirements of the KCSWDM for 100-year event (and also meets the requirements of the 25-year event) . Note: Historically we have found that the loading dock drains are the lowest inlets on the site. Despite the fact that the loading docks rarely generate significant runoff, they can be a controlling factor in the design of the conveyance system in order to meet backwater freeboard requirements . Neither the :Basin "C" loading dock or conveyance system serving it has -. been designed, therefore, no attempt has been made to analyze it for adequacy. During detailed design, the building finish floor, loading dock design, and location of the loading dock drain connection to the main drainage system should be carefully evaluated. \\CIVSEAADM1\DATA1\JOB\W3X32800\1102\Engr\BasinC&6\jjscalc0l['8.0] .doc KING COUNTY DEPARTMENT OF NATURAL RESOURCES Water and Land Resources Division BACKWATER ANALYSIS PROGRAM Version 5.30f RUN DATE: 8/31/00 PROJECT: Longacres Office Park Conceptual Drainage Report for Master Plan Development Sverdrup Job No. W3X32800 Master Plan Basin "C" During 100-YR 24-HR Event INPUT FILE: W3X32800/1102/ENGR/BACKWATR/C_100yr.bwp INPUT DATA FILE: PIPE NO. 1: 500 LF - 27"CP @ 0.40% OUTLET: 12.59 INLET: 14.59 INTYP: 4 JUNC NO. 1: OVERFLOW-EL: 21.00 BEND: 90 DEG DIA/WIDTH: 4.0 Q-RATIO: 0.41 PIPE NO. 2: 50 LF - 24"CP @ 0.40% OUTLET: 14.84 INLET: 15.04 INTYP: 4 JUNC NO. 2: OVERFLOW-EL: 21.00 BEND: 0 DEG DIA/WIDTH: 4.0 Q-RATIO: 0.11 PIPE NO. 3 : 205 LF - 24"CP @ 0.40% OUTLET: 15.04 INLET: 15.86 INTYP: 4 JUNC NO. 3 : OVERFLOW-EL: 21.00 BEND: 0 DEG DIA/WIDTH: 4.0 Q-RATIO: 0.57 PIPE NO. 4: 375 LF - 21"CP @ 0.40% OUTLET: 16.11 INLET: 17.61 INTYP: 4 JUNC NO. 4: OVERFLOW-EL: 21.50 BEND: 90 DEG DIA/WIDTH: 4.0 Q-RATIO: 2.33 PIPE NO. 5: 285 LF - 15"CP @ 0.40% OUTLET: 18.11 INLET: 19 .25 INTYP: 4 INPUT DATA: BACKWATER COMPUTER PROGRAM FOR PIPES Pipe data from file:C_100yr.bwp Surcharge condition at intermediate junctions Tailwater Elevation:16.55 feet Discharge Range:0.1 to 17.13 Step of 0.1 [cfs] Overflow Elevation:22.5 feet (most upstream catch basin) Weir:NONE Upstream Velocity:0.1 feet/sec REFINED OUTPUT: Refer to the following pages.

It was then estimated that the office park would be developed over a ten to fifteen year period according to Boeing's corporate needs. In preparation for site development, Boeing now proposes to enter into a development agreement with the City pursuant to the requirements of RCW 36.70B.170 through .210. The agreement will describe the basic parameters of the proposed office park development and will be based on the 1994 EIS and additional environmental analysis of certain aspects of the project. The updated environmental analysis will also discuss any additional impacts caused by increasing the height of certain buildings to achieve a 500,000 square-foot increase in total gross floor area of the office park. This report documents programmatic transportation impacts associated with the Boeing LOP— Master Plan Update at a proposed total buildout of 3.0 million square-feet of office uses. Two separate trip generation scenarios were used to evaluate the proposed buildout of 3.0 million sf of office. These scenarios included: 1. Using methods and assumptions consistent with those documented in Chapter 14 — Transportation of the Renton/Boeing DEIS — Boeing Longacres Office Park, August 1994, accounting for mode split adjustments given the adjacent Tukwila commuter rail station and multimodal center, and built office uses in operation within the mitigation area,and 2. Using current transportation engineering methods and assumptions, and considering the adjacent Tukwila commuter rail station and multimodal center. Under either scenario, a net decrease in vehicle trip generation over vested buildout levels was found when evaluating the proposed buildout of 3.0 sf of office uses at Boeing LOP. Project impacts to ridership on commuter rail services are estimated at 400 one-way boardings during the p.m. peak hour in the reverse commute direction, resulting in a net increase of 300 one-way daily boardings over current ridership estimates. This demand for ridership however, would be in the reverse commute direction and would not adversely impact excess passenger capacity of commuter rail operations. To minimize.impacts of this ridership demand, the applicant would install an appropriate crossing treatment on Jackson Avenue SW to minimize conflicts between vehicle traffic and employee walk access, and to provide a safe and attractive route for commuter rail patrons between the Tukwila Multimodal Station and Boeing LOP. The project applicant would also implement traditional transportation demand management (TDM) programs through a series of parking management strategies, subsidy elements and incentives, site amenities, work schedule and other special programs and operations to reduce project impacts during peak commute periods and meet Commute Trip Reduction (CTR) requirements. Transportation Engineering NorthWest,LLC September 29,2000 1 1 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study INTRODUCTION This study documents programmatic transportation impacts associated with the proposed Boeing LOP—Master Plan Update, located in Renton,WA (see Figure 1). Based on discussions with the City of Renton, the following tasks were undertaken to analyze transportation impacts associated with the proposed action: ➢ Documentation of the proposed project location and action. > Assessment of existing conditions through field reconnaissance and review of existing planning documents. > Identification of planned roadway improvements. > Evaluation of existing operations for weekday vehicular a.m. peak hour,p.m. peak hour trips, and daily trips generated at existing office uses within the mitigation area,which includes Building 25-10 (Family Center) and Building 25-20 (BCAG Corporate Headquarters). > Estimation of future weekday vehicular a.m. peak hour,p.m. peak hour trips, and daily traffic that would be generated by the Boeing LOP at full buildout. > Evaluation of traffic impacts in relation to site access and public transportation issues. ➢ Documentation of existing mitigation requirements and agreements. > Recommended project mitigation as a result of the Master Plan Update.

PROJECT DESCRIPTION In 1994, Boeing submitted an EIS to the City of Renton describing the environmental impacts of a 164-acre, 2.5 million square-feet master planned development including offices, an employee center, related support and utility facilities, and open space amenities. It was then estimated that the office park would be developed over a ten to fifteen year period according to Boeing's corporate needs, and would include approximately 10,000 employees at full buildout. In 1995, the City of Renton issued a Mitigation Document for the office park setting forth required mitigation for project development. Two buildings have been constructed since 1995 — BCAG Headquarters (in 1997) and Renton Family Care Center (1998). In 1999, the Surface Waster Management Project (SWMP) was constructed. SWMP is a stormwater system for the office park consisting of a combination of wetponds, detention ponds and created wetlands sized to accommodate the master plan at full buildout. In preparation for site development, Boeing now proposes to enter into a development agreement with the City pursuant to the requirements of RCW 36.70B.170. The agreement will described the basic parameters of the proposed office park development and will be based on the 1994 EIS and additional environmental analysis of certain aspects of the project. The updated environmental analysis will also discuss any additional impacts caused by increasing the height of certain buildings to achieve a 500,000 square-foot increase in total gross floor area of the office park. The development agreement will also establish applicable development regulations,including development standards set forth in the Renton Code, a vesting framework, and other restrictions. The following paragraphs summarize the proposed Boeing Longacres Office Park (LOP) — Master Plan Update in relation to its general location, a description of the proposed action and existing zoning characteristics. Project Location The proposed 158-acre Boeing LOP is located in Renton, WA, at the site formerly comprising the Longacres Park Racetrack (Figure 1). Regional access to the site would be provided primarily via Interstates 5 and 405 (I-5 and I-405) and State Route (SR) 167. Existing major J September 29,2000 Transportation Engineering Northwest, LLC Page 4 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study principal arterials that would provide access to the site include Oaksdale Avenue, SW Grady _ Way, SW 16th Street, and SR 181/West Valley Highway. Within the City of Renton, the property is generally bounded by The Boeing Company's Customer Services Training Center to the north, approximately 1,000 feet south of SW 27th Street alignment to the south, the Burlington Northern Santa Fe (BNSF) mainline railroad track to the west, and at or roughly 500 feet east of Oaksdale Avenue. Description of Proposed Action Full occupancy of the project site would take place between 2005 and 2010 depending on the corporate needs of The Boeing Company. The proposed LOP Master Plan Update would increase the proposed office space from approximately 2.5 million square-feet to 3.0 million square-feet in gross floor area. The proposed action would also include 79 acres of landscaping and a lake to serve as a water amenity and storm water detention.system. A roadway network within the site would provide access and circulation within the site and to the major transportation arterial network adjacent to the site. Project site driveways would access directly onto Oaksdale Avenue SW, SW 27th Street and Jackson Avenue SW. Currently, two buildings (totaling 330,905 square feet) have been constructed as part of the Boeing LOP Development. One main building, a 308,900 square foot office complex that comprises the Commercial Airplane Group Headquarters (Building 25-20), and a 22,000 square foot employee daycare facility known as the Family Center (Building 25-10). A general layout of the proposed Boeing LOP Master Plan Update yet to be developed is shown in Figure 2. Existing Zoning The LOP site is located within an area designated Commercial Office by Renton City code. This zoning designation provides for professional, administrative, and business offices as primary uses. Secondary uses include support to primary uses including day care centers, financial institutions, and limited retail sales. Some light industrial uses are also allowed as secondary uses. The primary purpose of the proposed action is to vest development rights to current zoning requirements and.other City standards. EXISTING CONDITIONS This section generally describes existing transportation system conditions in the study area. It includes a summary of existing roadways, traffic volumes, public transportation services, and planned roadway improvements. 1 1 Engineering NorthWest LLC September 29,2000ge5 Transportation Page 5 • Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study 1 i ..., T, 161N if11EEf ... - ..1*: ' , C. r 33 3 i -!wi .� i Itt 1 •5, n11 I, 1: t '' it i J 1 ii p.N....„S ;{ 1 3 '3 :y R -�_ .��-_.�_-_��-_ =__--�-_ram^- .... ____1 Master II Plan Area 3 11. i f J,.....'-.w......-� BOEING LONGACRES OFFICE PARK RENTON, WASHINGTON j • 1' .

Engineering Northwest LLC September 29,2000 Transportation Page 14 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Sound Transit and King-County Metro The Tukwila Multimodal Station would be located south of S Longacres Way/S 158th Street/158th Street and north of the future SW 27th Street/Strander Boulevard right-of-way and bounded to the east and west by the Union Pacific and BNSF mainline railroad tracks. Access to the station would be provided via S Longacres Way/S 158th Street and SW 27th Street/Strander Boulevard. The multimodal station would function as part of a regional transit system serving vehicular traffic, commuter rail, buses, pedestrian and bicyclists. The Tukwila Multimodal Station is expected to open in late Spring 2001. It would be one of eight stations to be built along the initial 40-mile Tacoma-to-Seattle Sounder commuter rail line. Eventually, the system would be expanded to serve additional communities from Lakewood to the south and Everett to the north. As part of construction of the Tukwila Multimodal Station, a park-and-ride facility would be provided. Initially constructed with approximately 430 stalls, the ultimate buildout would provide parking for 630 vehicles by 2010. Commuter rail users are expected to arrive at the Tukwila Station by the following modes: driving or riding in a private vehicle, riding in a feeder or local bus, or walking or bicycling. When the Tukwila Station opens in late spring of 2001, Sound Transit would operate a minimum of 2 trains running per day with ridership estimated at approximately 200 a.m. boardings commuter rail, generating 200 vehicular trips. The number of commuter rail trains, passenger boardings and park-and-ride lot parking spaces would gradually increase until full operations are provided. At full operations (2007-2010), the Sounder line would run in each direction at half-hour intervals during peak commute periods between 6 a.m. to 9 a.m. and 4 p.m. to 7 p.m. As such, at full operation, the Tukwila Multimodal Station would be served by approximately 18 train trips per day, 9 trips in the morning and 9 trips in the evening with 6 trips inbound and 3 trips outbound for both morning and evening commuter peak periods. King Country-Metro plans to serve the Tukwila Multimodal Station via Route 140 (formerly known as Route 340) and potentially re-route Route 140 to serve the Boeing Longacres Office Park. The new transit route would continue to serve SW Grady Way but would then head south on Oaksdale Avenue SW, west on SW 16th Street, access the Boeing Frontage Road, head south on Jackson Avenue SW, head west under the underpass on S.Longacres Way/S 158th Street and then serve the Tukwila Multimodal Station. For this routing change to occur, the underpass on S Longacres Way/S 158th Street would need to be re-opened. The routing change would occur with the opening of the Tukwila Multimodal Station, potentially late spring of 2001. No other transit routes would serve the station given the limited 2 peak hour commuter rail runs per weekday that would be provided initially. However, when the station becomes fully operational by 2010, King County-Metro would divert more service to Tukwila Multimodal Station, but service times and routes have yet to be determined.

The discussion includes vehicular trips generated by the proposed action, transit ridership and mode share estimates,vehicular site access, circulation, and safety issues. Project Trip Generation The methodologies used to prepare trip generation estimates of the proposed office space buildout of 3.0 million sf at Boeing LOP involved three main efforts: 1. Documentation of vehicular trip generation by existing office uses within the Mitigation Area at Boeing LOP (i.e.,Buildings 25-10 and 25-20). 2. Estimation of total site vehicular trip generation using the methods and assumptions consistent with those documented in Chapter 14—Transportation of the Renton/Boeing DEIS — Boeing Longacres Office Park, August 1994, with adjustments made for mode split given the adjacent Tukwila commuter rail station and multimodal center between Longacres Way (SW 158th Street) and SW 27th Street along Jackson Avenue SW. 3. Estimation of total site vehicular trip generation using current transportation engineering methods and assumptions and considering the adjacent Tukwila commuter rail station and multimodal center. Vehicular Trip Generation of Existing Buildings and Uses A trip generation study was conducted by TENW for existing uses within the Mitigation Area at Boeing LOP. Traffic Data Gathering, a local traffic counting firm, conducted 24-hour traffic counts over a 3-day period in August 2000 at 5 existing site driveway locations that serve Buildings 25-10 and 25-20. Daily, a.m. peak hour, and p.m. peak hour counts at the existing driveway locations are summarized in Table 1. Average weekday trip generation of existing offices uses at Boeing LOP is approximately 3,250 daily, 360 a.m. peak hour, and 390 p.m. peak hour vehicle trips.

September 29,2000 Transportation Engineering Northwest, LLC Page 16 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study - Table 2 summarizes the results of the trip generation study by building, identifying the total number of vehicles entering and exiting office uses within the Mitigation Area. These buildings comprise approximately 330,905 square-feet in gross floor area,with 835 employees. Employee density of existing office uses (i.e., Building 25-10) is approximately 2.5 employees per 1,000 sf of gross floor area. Existing employee densities are nearly 25 percent lower than average densities (3.3 employees per 1,000 sf of gross floor area) of similar office uses published in the Institute of Transportation Engineering (ITE), Trip Generation Manual, 66 Edition, 1997.

The following methods and assumptions were used to estimate vehicular trip generation at full buildout: Total office building square footage: 2,500,000 sf. Employment Levels: 10,000 employees. Employee Density: 4.0 employees per 1,000 sf of gross floor area. ITE Trip Generation Rate: Average Rate per Employee, 3.62 daily trips, 0.52 a.m. peak hour, and 0.50 p.m. peak hour trips per employee. ITE Land Use Code: 715 Single-Tenant Office. Average Vehicle Occupancy of Vehicle Trips: 1.1 persons per vehicle during peak periods, and 1.08 persons per vehicle for daily trips. Engineering Northwest, LLC September 29,2 00 17 Transportation Page 17 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study The resulting vehicle trip generation using the above assumptions is approximately 36,200 daily, 5,200 a.m. peak hour, and 5,000 p.m. peak hour vehicular trips before any mode split adjustments are made (for detailed trip generation calculations, see Table A-1 in Appendix A). Converting these vehicular trip generation estimates to person trips results in an estimated 39,100 daily, 5,270 a.m. peak hour, and 5,500 p.m. peak hour person trips at full buildout of 2.5 million sf. It should be noted, that this method uses the most conservative trip generation rate for office uses. Mode Split Adjustments used in FEIS Modal shares of person trips, average vehicle occupancy, and resulting non-HOV vehicular trip generation rates consistent with those outlined in Chapter 14, of the Renton/Boeing DEIS—Boeing Longacres Office Park, August 1994, were applied to person trip estimates. A conservative non- HOV rate of 78 percent during peak travel periods,and 81 percent throughout a typical workday results in a net trip generation of approximately 28,900 daily, 4,250 a.m. peak hour, and 4,085 p.m. peak hour vehicle trips (for detailed trip generation calculations of this scenario, see Table A-1 in Appendix A). This net vehicular trip generation estimate was used to evaluated traffic impacts of the original 2.5 million sf of office buildout and prepare the Longacres Office Park EIS Mitigation Document, May 1995. This Mitigation Agreement contains a list of specific transportation improvements that would be constructed, and traffic mitigation fees payable to the cities of Renton and Tukwila by the applicant. Trip Generation Estimates using Current Transportation Engineering Methods A comparison of the application of all potential office trip generation rates and categories documented with the ITE Trip Generation Manual, 6th Edition, 1997, was conducted by TENW. This effort was undertaken to determine the most applicable approach to estimate trip generation using current transportation engineering methods and to be consistent with other processes used at other major office and mixed-use developments within Renton. Table A-2 in Appendix A provides a comparative summary of trip generation rates for office uses applied to building square-footage and employee density assumptions vested in the original Boeing LOP Master Plan (i.e., 2.5 million sf of office and 10,000 employees). It was determined that the trip generation rate applied during the documentation of environmental impacts in 1994/95 is the most conservative rate (i.e. average trip rate per employee for Land Use Cod 715 — Single- Tenant Office), resulting is trip estimates that are 33 percent and 63 percent higher than aggregate average rates on a p.m. peak hour and daily basis,respectively. In reviewing the description of the proposed action and the application of comparable trip generation rates based on office uses published in the ITE Trip Generation Manual, 66 Edition, the average trip rate per 1,000 sf of gross floor area for Land Use Code 710 — General Office is more applicable to the project action (given existing employee densities and other recent studies in the City of Renton), and results in trip generation rates that are fairly close to aggregate averages shown in Table A-2 in Appendix A. ag September 29,2000 Transportation Engineering NorthWest,LLC Page 18 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study As such, the average trip rate per 1,000 sf of gross floor area for ITE Land Use Code 710 — General Office was selected to estimate gross vehicular trip generation of the proposed 3.0 million sf under the Boeing LOP Master Plan Update. It should be noted, that by the use of an average trip generation rate per employee or per gross floor area, no adjustments are made to account for the ultimate size of office uses. It is well documented in the ITE Trip Generation Manual, that as office size increases, the trip generation rate per unit diminishes. In addition, no trip reductions or internalization assumptions were made between the proposed action and the 20-acre transit-oriented development that is proposed at the Sound Commuter Rail station and Tukwila Multimodal Center. Therefore, these estimates using current transportation engineering methods should be considered conservative. Mode Split Adjustments Given Sounder Commuter Rail/Tukwila Multimodal Center Recent mode split research completed by TENW as part of the I-405/NE 44th Street Interchange (Port Quendall) as well as other recent studies and commuter rail forecasts were evaluated for their application to the proposed Boeing LOP Master Plan Update. This effort was conducted to evaluate adjustments to mode share assumptions originally made for the Boeing LOP given the adjacent commuter rail services and transit center. Our research concluded that peak period non-HOV mode splits of approximately 65 percent could be achieved at locations in close proximity to moderate transit service levels and the implementation of traditional transportation demand management (TDM) measures at the site. In addition, given the "single-use" nature of the proposed action, a 75 percent non-HOV mode split could be achieved outside of peak commute periods. These non-HOV mode splits compare to a 78 percent and 81 percent non-HOV mode split assumed in the original documentation of environmental impacts of the Boeing LOP for peak period and daily trips, respectively. FEIS Trip Generation Rates with Updated Mode Split A net decrease in vehicle trip generation over vested buildout levels results when considering the proposed buildout of 3.0 million sf of office, existing uses built and in operation at the site, and the adjacent Sounder commuter rail station and Tukwila Multimodal Center. Table A-3 in Appendix A summarizes adjustments made to mode split assumptions in the original FEIS to account for future service levels at the adjacent Tukwila commuter rail station and multimodal center. Net vehicle trip generation is estimated at 28,000 daily, 3,775 a.m. peak hour trips, and 3,630 p.m. peak hour trips using the employee density assumptions and trip generation rates documented in the Renton/Boeing DEIS—Boeing Longacres Office Park,August 1994, with updated mode splits. These net vehicular trip generation estimates are approximately 3 percent less on a daily basis and 11 percent less on a peak hour basis than those vehicle trip generation levels used to identify transportation improvements and mitigation in the Longacres Office Park EIS Mitigation Document, May 1995. As such, when considering existing uses at the site, FEIS trip generation methodology, and adjusting for adjacent development and operation of the Sounder commuter rail station and Tukwila Multimodal Center, net vehicle trips generated by 3.0 million sf of office space at Transportation Engineering Northwest, LLC September 29,219 Pagege 19 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Boeing LOP would be less than those levels evaluated and vested as part of the original Boeing LOP Master Plan development action at 2.5 million sf of office. Current Trip Generation Methods and Updated Mode Split Using more current trip generation methods and applying non-HOV mode splits of 65 percent during peak periods and 75 percent during off peak periods, net vehicle trips generated by 3.0 million sf of office space at Boeing LOP would be 17 percent less on a daily basis, and roughly 25.percent less on a peak hour basis than those trip generation levels evaluated and vested at 2.5 million sf of office (for detailed trip generation calculations of this scenario, see Table A-4 in Appendix A). Table 4 summarizes the results of trip generation evaluation for the Boeing LOP Master Plan Update under the two scenarios requested by the City of Renton. As shown, net vehicle trip generation estimates assuming 3.0 million sf of office uses using previous methods and assumptions, that are adjusted to reflect adjacent commuter rail service and Tukwila Multimodal Center and existing office uses built at the site, are estimated to be 3 percent less on a daily basis, and 11 percent less on a peak hour basis than those trip generation levels vested at an office buildout of 2.5 million sf. If current trip generation methodologies are applied,net vehicular trip generation is estimated at 17 percent less on a daily basis, and 25 percent less on a peak hour basis, than vested trip generation levels. As such, with an additional 500,000 sf of office uses at Boeing LOP as proposed under this Master Plan Update, no net increase in vehicle trip generation is expected to result beyond those levels documented in the original FEIS.

'Frans ortation N September 29,2000 p Engineering orthWest, LLC Page 20 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Site Access and Circulation Access to the existing site is currently provided via 5 existing driveways onto Oakesdale Avenue SW. Vehicular access at existing site driveways are regulated by a center, two-way left-turning lane, which minimizes turning movement impacts into and out of project driveways on roadway operations. A fully-actuated traffic signal is currently located on Oakesdale Avenue SW at its intersection with site driveways leading to the BCAG Headquarters (Building 25-10) to the west, and the Family Center (Building 25-20) to the east. Future vehicular access would be provided onto Oaksdale Avenue SW,Jackson Avenue SW, and SW 27`h Street. Driveways locations and off-sets relative to adjacent intersections and driveways would be designed based on standard traffic engineering methods and practices and in accordance with local guidelines as follows: > No driveways would be located within a minimum of 150 feet of an arterial intersection. > Minimum spacing standards of 150 feet between driveways along roadways would be developed such that adequate left turning storage is provided, traffic flow constraints are reduced, and turning movement conflicts are minimized. > Opposing driveways would be aligned when possible, or offset by 150 feet. > Access and egress control at most driveways where moderate volumes are expected would be afforded through center, two-way left-turning lanes on public streets. Separate right-turn only or left-turn only lanes would be provided where moderate to high turning movements are anticipated and located where volume warrants are met. Public Transportation Impacts Ridership forecasts at the Tukwila Multimodal Station by 2010 are estimated at 800 a.m. commuter rail boardings, and 100 reverse direction (p.m. inbound and a.m. outbound) commuter rail boardings. Sound Transit estimates access mode shares to the station during peak periods as 50 percent bus transfer, 45 percent park-and-ride, and 5 percent via nonmotorized modes. These ridership forecasts prepared by Sound Transit were made prior to the Boeing LOP Master Plan that was completed in 1995, and assumed continued operation of the Longacres Race Track. Commuter rail ridership estimates prepared by TENW of the Boeing LOP campus itself is estimated at 400 inbound and 400 outbound passengers per day at the Tukwila Multimodal Station at full buildout. Inbound commuter rail ridership of 100 reverse direction boardings per day prepared by Sound Transit assumed the construction of a convention center and other supporting uses at the station. Given that a convention center and the Longacres Race Track are no longer anticipated or in use at the site, an estimated net increase in commuter rail ridership of approximately 300 inbound reverse direction boardings per day would result due to Boeing LOP Master Plan over those ridership projections prepared by Sound Transit in 1992. Note: these commuter rail ridership projections do not include any ridership potential of the proposed 20-acre transit-oriented development at the Tukwila Multimodal Station that is being proposed jointly by Sound Transit and the City of Tukwila. a9 Transportation Engineering NorthWest,LLC September 29,g Page 21 21 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Nonmotorized Transportation Impacts Pedestrian access to the eastern platform of the Tukwila Multimodal Station would be provided via the existing grade-separated underpass at S Longacres Way/S 158th Street. A pedestrian tunnel would connect both sides of the train tracks. Walkways and roadways would also be improved to enhance pedestrian access to the Station area. Access to the station area from Boeing LOP should be made via an appropriate crossing treatment on Jackson Avenue SW within a minimum of 300 feet of the passenger boarding/alighting area at the Tukwila Multimodal Station. Placement of office buildings in the immediate vicinity of the station area within the Boeing LOP campus, internal walkways and employee entrances would be designed to minimize pedestrian-vehicle conflicts and walking distance of walk access trips to commuter rail and transit services at the Tukwila Multimodal Center. PROJECT MITIGATION When considering existing uses at the site and adjusting for adjacent development and operation of the Sounder commuter rail station and Tukwila Multimodal Center, net vehicular trips generated by the proposed 3.0 million sf of office space under the Master Plan Update would be less than those levels evaluated and vested as part of the original Boeing LOP Master Plan development action (at 2.5 million sf of office). i In summary, no net increase in vehicle trip generation over what was estimated in the FEIS is anticipated as part of the proposed action. Table 5 summarizes general impacts of the proposed action and describes actions proposed to reduce or eliminate project impacts. The following pages further document in detail existing transportation mitigation requirements and agreements between Boeing, the cities of Renton and Tukwila, and adjacent property owners with respect to buildout of the Boeing Longacres Office Park. Mitigation Requirements and Agreements Previously Established Street Improvements Oaksdale Avenue SW The Longacres Office Park EIS Mitigation Document, May 1995, identified site improvements pertaining to the Oakesdale Avenue SW extension. One of the mitigation agreements identified the construction of a private two-lane roadway by Boeing within the alignment for the Oakesdale Avenue SW extension. Other mitigation agreements related to right-of-way reservations and dedications for the private roadway and Oakesdale Avenue SW. The City of Renton was also to commence construction of the Oakesdale Avenue SW extension before the buildout of Longacres Office Park, or within 20 years, or the required mitigation was null and void. i Transportation Engineering NorthWest, LLC September 29,g Page 22 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study Table 5: Mitigation to Address Project Impacts of Boeing LOP Master Plan Update Impacts Description Project Mitigation Trip generation during peak Net vehicle trip generation is The project applicant would implement commute periods. estimated at 28,000 daily, 3,775 traditional transportation demand a.m. peak hour trips, and 3,630 p.m. management(TDM) programs through a peak hour trips assuming non-HOV series of parking management strategies, mode splits of 65%during peak subsidy elements and incentives, site commute periods and 75%on a daily amenities, work schedule and other basis. special programs and operations to reduce project impacts during peak commute periods and meet Commute Trip Reduction (CTR) requirements.

The roadway would include curbs, gutters, sidewalks, bicycle lanes, traffic control markings, signing and signalization, lighting,landscaping and drainage facilities. ➢ Phase I would include a 2-lane roadway between SW 16th and SW 27th Street with frontage improvements on the west side of the roadway. Status: complete. ➢ Phase II would include the completion of two more lanes from SW 16th Street to SW 27th Street, and four lanes from SW 27th Street to SW 31st Street with frontage improvements on both sides of the roadway. Status: not complete. Boeing's and the City of Renton's responsibilities would include the following: ➢ Boeing will construct a private two-lane road within the alignment of the Oaksdale Avenue extension, following design, permitting, right-of-way, and contracting practices and standards to allow the City of Renton to qualify for grant funding for the extension, and adding the subgrade and drainage to support a five-lane roadway. Status: complete. ➢ Boeing will reserve the right-of-way for a 5-lane roadway from SW 16th to SW 27th Streets, and will reserve half the right-of-way for a five-lane roadway from SW 27th Street to the south property line. Status: complete. ➢ Boeing will record a covenant to encumber the right-of-way reservation for dedication and to bind its successors with the mitigation required under the Agreement until the LOP is built out or for 20 years,whichever is earlier. Status: complete. ➢ When the City proceeds with the Oaksdale construction,Boeing will dedicate the private road right-of-way and improvements to the City. Status: not complete. ➢ When the City proceeds with the Oaksdale construction, Boeing will sell to the City the additional right-of-way necessary for the 5-lane roadway,plus any additional right-of-way (e.g., Group Health, Drainage District #1), plus Boeing's additional costs for subgrade and drainage for a 5-lane road and other similar costs. Status: not complete. ➢ If the City is ready to proceed with the Oaksdale construction when Boeing is to construct its private road, Boeing will dedicate the full 5-lane right-of-way to the City, and the City and Boeing will cooperate to minimize interference with Boeing's activities on the site. Status: not complete. ➢ Additionally, Boeing will pay $2,512,00 toward the development of Oakesdale Avenue extension across LOP, according to a fixed payment schedule of four installments from 8/1/97 to 11/1/98. Payments to date have included: $800,000 (7/97), $343,179 (4/98), and $1,186,311 (8/98), totaling $2,329,490. As of September 17, 1999 a spreadsheet Transportation Engineering Northwest,LLC September 29,2024 Page 24 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study prepared by the Oaksdale Avenue Steering committee indicated that Boeing's commitment to the Oaksdale extension project had increased to $2,769,717. Status: partially complete, remaining obligation estimated at$440,227. > The City of Renton would complete Phase II of the Oaksdale Avenue extension at no cost to Boeing. Status: not complete. SW 27h Street Other elements in the Memorandum Agreement in November 1997 were related to right-of- way, easement and environmental areas as they relate to SW 27th Street. Dick McCann Memorandum to Phil Cyburt and Colette Temmink Regarding Right of Wray Reservation on Longacres Property for Strander Boulevard, December 30, 1999, identified the agreement between Broadacres, Inc., owner of the Longacres Racetrack and the City of Renton in on May 11, 1984. The agreement reserved a 90-foot right-of-way for the westerly extension of SW 27`h Street to Strander Boulevard. The agreement prohibits the construction of permanent structures within the reserved area for 25 years until May 10,2009. The property owner would be compensated at fair market value for any condemnation of the right-of-way within the 25-year period. The property owner would also be required to construct a local access road to provide access from SW 27th Street to parcels abutting the right-of-way that are rezoned and developed in any use incompatible with recreational horse racing. - Additionally,if and when the City of Renton constructs any westerly extension of SW 27th Street beyond its current terminus, any assessments or other charges allocated to Boeing to pay for some portion of the extension shall be reduced by no less than the full cost expended by Boeing in designing and constructing the local access roadway. Of the portion of SW 27th Street extension within the boundaries of LID 314 (i.e., between the its current terminus at Boeing's eastern property line and a point 300 feet east of the Burlington Northern Santa Fe right-of- way), Boeing allocated share of the cost of such portion of the extension, including water and sewer improvements,if any, shall not exceed 30 percent. Status: not complete. Impact/Mitigation Fees . The following impact or mitigation fees are currently attached to development at Boeing LOP: The Longacres Office Park EIS Mitigation Document, May 1995, identified Boeing's traffic mitigation fee to the City of Renton was set at $75 per vehicle trips, which amounted to $2,025,000 based on 27,000 daily trips. Impact fees are payable in increments at the time of each building permit application is submitted, based on the fee in effect at the time of permit application. Under the terms of the Mitigation Document for the Longacres Office Park (1995), Boeing has an option to pay a lump sum of $1,755,000 prior to 12/31/00, and fulfill its entire mitigation fee to the City of Renton. Status: partially complete,BRC has paid S157,500 to date. The City of Tukwila Longacres Park Transportation Mitigation Agreement, December 20, 1995, identified Boeing's traffic mitigation fee to the City of Tukwila at $1,029,560 based on an estimated 1,831 peak hour trips impacting City streets and an average $550 per vehicle trip. The Agreement allows the LOP a fixed total of 390 a.m. and p.m. peak hour vehicular trips on S September 29,2025 Transportation Engineering Northwest,LLC Page 25 Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study - Longacres Way/S 158th Street. The City reserves the right to assess additional traffic impacts fees against LOP for S Longacres Way/S 158th Street improvements. Status: not complete. Transportation Demand Management Programs Ridership on public transportation (i.e., transit, commuter rail, etc.) and attractiveness at the employment site trip-end is primarily related to parking management characteristics, transit accessibility and levels of service, and vicinity land uses within walking distance. Secondary issues include total travel time, congestion, and other available modal opportunities. Parking management strategies at the employment site are inherently part of the equation for transportation demand management, such as parking pricing strategies or carp ool/vanp ool incentives. To achieve non-HOV mode splits identified in this transportation study and to meet the requirements of Washington State's Commute Trip Reduction (CTR) Act of 1990,Boeing would implement a series of traditional transportation demand management (TDM) programs that would be targeted at employees working at the site. Types of specific TDM elements that would be considered at Boeing LOP are summarized in Table 6, however, no specific elements have been identified at this time. Boeing currently provides preferential parking for carpools and vanpools, subsidy for transit and other public transportation modes, work schedule options and staggered work shifts, and on-site transportation coordinators and ridematching services to existing employees at Boeing LOP and at many other of their employment sites throughout Renton and the Puget Sound region. I Status: not complete. This mitigation conditions would be new to Boeing LOP Master Plan.

Generally, as vehicular traffic volumes increase, the transportation system becomes more congested, and a commensurate increase in collision experience can occur. However, given existing safety conditions in the site vicinity and planned transportation improvements, it is anticipated that collision experience would remain similar to existing patterns and rates exhibited by existing facilities and not result in adverse impacts to public safety via transportation systems in the immediate site vicinity. Walk trips and access to the adjacent Tukwila Multimodal Station as well as other transit services in the immediate site vicinity could increase the potential for conflicts to occur between walking and bicycling activity and vehicle traffic. As such, general site development guidelines and planning of vehicular and pedestrian access points and related facilities would be developed to minimize as best possible the potential for conflict zones between motorized and nonmotorized modes. In addition the applicant, to ensure safe nonmotorized movements and access to the Tukwila Multimodal Station area, would construct an appropriate crossing treatment of Jackson Avenue SW. Status: not complete. This mitigation conditions would be new to Boeing LOP Master Plan. Remaining Mitigation Obligations of Applicant In summary, the following mitigation elements comprise remaining obligations of the applicant to reduce or eliminate transportation impacts of the proposed 3.0 million sf of office uses at Boeing LOP. Roadway Improvements > When the City proceeds with the Oaksdale construction, Boeing will dedicate the private road right-of-way and improvements to the City. > When the City proceeds with the Oaksdale construction, Boeing will sell to the City the additional right-of-way necessary for the 5-lane roadway, plus any additional right-of-way (e.g., Group Health, Drainage District #1), plus Boeing's additional costs for subgrade and drainage for a 5-lane road and other similar costs. > Remaining contribution toward the development of Oakesdale Avenue extension across LOP is estimated at $440,227 per the September 17, 1999, spreadsheet prepared by the Oaksdale Avenue Steering committee. > Upon development of offices uses abutting the SW 27th Street right-of-way, Boeing will construct a local access road to Renton City standards to provide site access. > Upon construction of the Stander Boulevard extension by the City of Renton, any assessments or other charges allocated to Boeing to pay for some portion of the extension - shall be reduced by no less than the full cost expended by Boeing in designing and constructing the local access roadway. Of the portion of SW 27th Street extension within the Transportation Engineering Northwest,LLC September 29,g 27 Page 7 l Boeing Longacres Office Park-Master Plan Update Renton,WA Transportation Study - boundaries of LID 314 (i.e., between the its current terminus at Boeing's eastern property line and a point 300 feet east of the Burlington Northern Santa Fe right-of-way), Boeing allocated share of the cost of such portion of the extension, including water and sewer improvements,if any, shall not exceed 30 percent. Traffic Mitigation Fees > Mitigation fees to the City of Renton are estimated at$75 per vehicle trips,which amounted to $2,025,000 based on 27,000 daily trips. Impact fees are payable in increments at the time of each building permit application is submitted, based on the fee in effect at the time of permit application. Under the terms of the Mitigation Document for the Longacres Office Park (1995), Boeing has an option to pay a lump sum of$1,755,000 prior to 12/31/00, and fulfill its entire mitigation fee to the City of Renton. > Traffic mitigation fees to the City of Tukwila are estimated at $1,029,560 based on an estimated 1,831 peak hour trips impacting City streets and an average$550 per vehicle trip. Transportation Demand Management Measures > Implement traditional transportation demand management (TDM) programs through a series of parking management strategies, subsidy elements and incentives, site amenities, work schedule and other special programs and operations to reduce project impacts during peak commute periods and meet Commute Trip Reduction (CTR) requirements. - Safety Improvements > Construct an appropriate crossing treatment of Jackson Avenue SW to ensure safe nonmotorized movements and access to the Tukwila Multimodal Station area from Boeing LOP. 19 September 29,2028

DEVELOPMENT AGREEMENT BETWEEN THE BOEING COMPANY AND THE CITY OF RENTON FOR FUTURE DEVELOPMENT OF LONGACRES OFFICE PARK I. PREAMBLE This DEVELOPMENT AGREEMENT ("Agreement") between THE BOEING COMPANY ("Boeing"), a Delaware corporation, and the CITY OF RENTON ("City"), a municipal corporation of the State of Washington, is entered into pursuant to the authority of RCW 36.70B.170 through .210, under which a local government may enter into a development agreement with an entity having ownership or control of Q real property within its jurisdiction. cp H. RECITALS A. Boeing is the owner of certain real property, known as the Longacres Office Park ("LOP"), located in the City of Renton, King County, Washington, and c; more particularly described in Attachment 1, attached hereto and by this reference incorporated herein. B. LOP consists of approximately 158 acres located at the southeast intersection of Interstate 405 and the Burlington Northern Railroad tracks in the City of Renton. Boeing's Customer Service Training Center ("CSTC") occupies an adjacent 48-acre site to the north and east of LOP. LOP is located entirely within the Commercial Office ("CO") zoning district and is designated Employment Center- Valley by the City's Comprehensive Plan. C. The master plan for LOP ("Master Plan") includes the construction of approximately 3 million square feet of office or light industrial space, related support and utility facilities, and open space amenities over a period of up to 15 years. Approximately 15 separate buildings would occupy the site upon completion. Of the 158 acres comprising the LOP site, the Master Plan proposes that approximately 79 acres will be impervious surface (i.e., buildings, parking areas or parking structures, and roadways), approximately 11 acres will be dedicated to a stormwater detention system, and approximately 68 acres will be devoted to landscaping and open space. The Master Plan is attached to this Agreement as Attachment 2 and incorporated herein by reference. D. Environmental analysis of development of 2.5 million sq. ft. under the Master Plan of the State Environmental Policy Act ("SEPA") was conducted by the City. A Draft Environmental Impact Statement ("DEIS") for the Master Plan was issued in August, 1994; the Final Environmental Impact Statement ("FEIS") was issued in March, 1995. A SEPA Mitigation Document ("Mitigation Document") was issued by the City in May, 1995. E. In 1997, Boeing developed the Boeing Commercial Airplane Group ("BCAG") headquarters office building, consisting of approximately 300,000 square feet, as Phase I of LOP. The location.and extent of Phase I development is depicted on Attachment 2. F. In 1998, Boeing developed the Boeing Family Care Center ("FCC"), consisting of approximately 22,000 square feet to provide day care services for 200 children as Phase II of LOP. The location and extent of Phase II development is depicted on Attachment 2. G. In 1999, Boeing developed a Surface Water Management Program ("SWMP"), consisting of grading to create stormwater ponds, an irrigation, aeration, and recirculation system, and enhanced wetlands designed to accommodate full build- out of LOP. The location and extent of Phase III development is depicted on Attachment 2. H. As part of the SWMP project, certain critical environmental areas on the Longacres site were identified. These areas include certain enhanced wetlands, the South Marsh, and a wildlife corridor.to be generally located between SWMP and the Marsh. On July 6, 1999, Boeing recorded a Declaration of Restrictive Covenants prohibiting development or alteration of the 10.92-acre South Marsh. Site wetlands (including South Marsh) and the area within which a wildlife corridor area will be located are depicted on Attachment 2. , I. Phase IV of the Longacres-Office.Park will consist of the development " of approximately 2.7 million square feet of office or light industrial space, with support and utility facilities, on that portion of LOP not developed under Phases I, II, and III or reserved for environmental mitigation purposes pursuant to development conditions. The Phase IV development will be constructed in multiple, campus-style buildings, with parking, roadways, and pedestrian walkways. The Phase IV development envelope is depicted on Attachment 2. J. Boeing and the City agree that Phase IV should be regulated and mitigated in order to provide certainty and efficiency with respect to the City's review and approval process for that development. .Accordingly, Boeing and the City agree as follows: III. AGREEMENT 1. Vesting and Term of Agreement. The City's development regulations in effect and applicable to project applications as of the date of recording of this Agreement shall govern the development of Phase IV of LOP for all Phase IV development applications submitted to the City within 15 years from the recording date of this Agreement. Notwithstanding the foregoing, the City reserves the authority under RCW 36.70B.170(4) to impose new or different regulations to the extent required by a serious threat to public health and safety, as determined by the Renton City Council after notice and an opportunity to be heard has been provided to Boeing. 2.

THE CITY COUNCIL OF THE CITY OF RENTON, WASHINGTON, DO ORDAIN AS FOLLOWS: SECTION I. Section 4-1-180.I.2.b(i) through(viii) of Chapter 1, Administration and Enforcement, of Title IV (Development Regulations) of Ordinance No. 4260 entitled "Code of General Ordinances of the City of Renton, Washington" is hereby amended as follows: i. Single Family: Seven hundred ninety-five dollars($795.00)per single family residence. ii. Mobile/Manufactured Homes: Six hundred thirty-five dollars ($635.00) per dwelling unit located in mobile home parks and manufactured home parks. iii. Multi-Family: Four hundred seventy-five dollars ($475.00) per multi-family residence, except in the Center Downtown (CD) and Center Office/Residential (COR) zoned areas which shall be assessed in accordance with subsection I.2.b(iv) of this Section. Mixed use buildings with over fifty percent (50%) of the floor space used for multi-family residences shall be assessed at the rate of four hundred seventy-five dollars($475.00)per multi-family residence. iv. Other: For all other properties except City properties, 10.6 cents ($0.106) per square foot of property connected but not less than seven hundred ninety-five dollars($795.00). v. Payment: Fees are incurred upon the granting by the City of a building permit or a construction permit, but are payable at the time construction permits are issued for connection to 1 ORDINANCE NO. 4 8 7 2 or extension of the public sewer; or in the absence of the requirement for a public works permit, then at the time of granting the building permit. All other sanitary sewer service applicants shall pay these fees at the time of building sewer application. vi. Fees Upon Sale: Fees are due immediately if the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the City agrees that the third party shall be responsible for that fee after determination that such an agreement would be in the City's best interest. The burden of establishing the agreement would be on the party owing the fee and not on the City, and would be in the City's best interest. vii. Definition: When the phrase "property which has not participated in development of the system"is used in this Section, it shall mean any of the following: • First Time Server Connection: Any property which has not paid a system development charge for the property based upon the square footage of the property and which is connecting to Renton's sewer system for the first time (including but not limited to new construction, or conversion from septic system). • Further Development or Subdivision: Any property which has not paid a system development charge for the property based upon the square footage of the property that is to be served by the utility and is developing or subdividing further. For example, one single family residence on a five (5) acre tract which has paid seven hundred ninety-five dollars ($795.00) under this Section to connect to a sewer system will have paid only for one, seven thousand five hundred (7,500) square foot lot at the rate of 10.6 cents ($0.106). Additional charges would be applied to any additional development on the property at the time of development. 2 .r ORDINANCE NO. 4 8 7 2 — • Larger or Additional Water Meters: Any property which has not paid a system development charge for the property based upon the square footage of the property that is to be served by the utility and that requests or requires a larger or additional domestic water meter(s) will trigger a utility system development charge. • Redevelopment Credit: An option exists for receiving a redevelopment credit for property which has not previously paid.in full a system development charge. A redevelopment project that requires a larger water meter, or additional domestic water meter(s), will trigger the sewer utility system development charge. However, any parcel that currently has water service is eligible for a prorated system development charge. This prorated development charge is based on the following formula: (Proposed domestic meter(s) capacity in gallons per minute (GPM) — Existing domestic meter(s) capacity in GPM/Proposed domestic meter(s) capacity in GPM) x SDC Fee = Amount owed. Fire flow meters are not included in this calculation. For example, a redevelopment project that involves a change from a single family home on a ten thousand (10,000) square foot lot with a five-eighths inch by three-quarter inch meter (5/8" x 3/4", a standard single family meter) that has a safe operating capacity of twenty (20) gallons per minute (GPM), to a four (4) unit multi-family dwelling with a one and one-half inch (1-1/2") meter with a safe operating capacity of one hundred(100) GPM can apply to pay for the following prorated charge: (100 GPM—20 GPM/100 GPM)=0.8 0.8 x(10,000 sq. ft. x$0.106/sq. ft.)=$848.00 Without the redevelopment credit, this project would have paid $0.106/sq. ft. x 10,000 sq. ft. = $1,060.00. 3 ORDINANCE NO. 4 8 7 2 The City will determine the safe maximum operating capacities of all meter sizes using American Water Works Association tables (see subsection I.4.b(ix) of this Section). The fee paid shall be recorded and applied to the total system development charge applicable for the parcel. Reduction in water meter capacity shall not result in a payment from the City to the applicant. • Fire Protection Credit: Installation of a water meter solely for a fire protection system, such as a new hydrant or fire sprinkler system, shall not trigger a sewer system development fee. viii. Short-Term Use: Temporary connections to the City's sewage system may be granted for a one-time, temporary, short-term use of a portion of the property for a period not to exceed three (3) consecutive years. Permission for temporary connection may be granted upon payment of an annual fee equal to ten percent (10%) of the current system development charge applicable to that portion of the property, but not less than seven hundred fifty dollars ($750.00) per year. Said fee shall be paid annually (nonprorated), and shall be nonrefundable, nontransferable (from one portion of the property to another) and shall not constitute a credit to the system development charge due at the time of permanent use of the utility system. The application for temporary connection shall consist of a detailed plan and a boundary line of the proposed development service area for use in the fee determination. SECTION II. Section 4-1-180.I.3.b(i) through (v) of Chapter 1, Administration and Enforcement, of Title IV (Development Regulations) of Ordinance No. 4260 entitled "Code of General Ordinances of the City of Renton, Washington"is hereby amended as follows: i. Residences and Mobile Homes: Five hundred twenty-five dollars ($525.00) per single family residence and mobile home dwelling. 4 ORDINANCE NO. 4 8 7 2 ii. Other Properties: For all other properties except City properties, 17.5 cents ($0.175) per square foot of new impervious area of property proposed by the permit application, but not less than five hundred twenty-five dollars($525.00). iii. Issuance of Permits: Fees are incurred upon the granting by the City of a building permit, but are payable at the time construction permits are issued for connection to or extension of the public surface water collection system; or, in the absence of the requirement of a public works permit,then at the time of granting the building permit. iv. When Due: Fees are due immediately, notwithstanding subsection I.3.b(iii) of this Section, the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the City agrees that the third party shall be responsible for that fee after determining that such an agreement would be. in the City's best interest. The burden of establishing that the agreement would be in the City's best interest would be on the party owing the fee and not on the City. v. Definition: When the phrase "property which has not participated in development of the system" is used in this Section, it shall mean any of the following: • First Time Surface Water Connection: Any property which has not paid a system development charge for the property based upon the square footage of new impervious surface of the property and which is connecting to Renton's surface water collection system for the first time(including but not limited to new construction). • Further Development or Subdivision: Any property which has not paid a system development charge for the property based upon the square footage of new impervious surface of property that is to be served by the utility and is developing or subdividing further. For example, one single family residence of a five (5) acre tract which has paid five hundred twenty-five 5 ORDINANCE NO. 4 8 7 2 dollars ($525.00) under this Section to connect to a surface water collection system will have paid only for one, seven thousand five hundred (7,500) square foot lot at a rate of 17.5 cents ($0.175) per square foot of impervious area. Additional charges would be applied to any additional development on the property at the time of development. • Runoff Quantity Control: Any property for which one hundred percent (100%) of the surface water runoff quantity control requirements can be met by infiltration systems, as allowed by code, will be exempted from the surface water charge. • Existing Developments: Property that was developed before the effective date hereof is exempted from the connection charge. Any rebuilding, change in use or additions to exempted property that does not require additional surface water runoff capacity will not trigger a new connection charge. However, when property is redeveloped or the use changed or intensified such that a larger surface water drainage capacity is necessary, then any application for rebuilding will trigger a utility connection charge. "Surface water drainage capacity" is defined as computed maximum peak rate runoff from the site prior to entering public or private stormwater facilities. Improvements to existing single family residential units such as additions, decks, small sheds and other minor improvements are exempt from the system development charge unless a new connection to the Renton surface water utility collection system is proposed or required as part of the permit application. SECTION III. Section 4-1-180.I.4.b(i)through(viii) of Chapter 1, Administration and Enforcement, of Title IV (Development Regulations) of Ordinance No. 4260 entitled "Code of General Ordinances of the City of Renton,Washington"is hereby amended as follows: i. Single Family: One thousand, one hundred eighty dollars ($1,180.00) per single family residence. 6 ORDINANCE NO. 4872 ii. Mobile/Manufactured Homes: Nine hundred forty dollars ($940.00) per dwelling unit located in mobile home parks and manufactured home parks. iii. Multi-Family: Seven hundred ten dollars ($710.00) per multi-family residence, except in the Center Downtown (CD) and Center Office/Residential (COR) zoned areas which shall be assessed in accordance with subsection I.4.b(iv) of this Section. Mixed use buildings with over fifty percent (50%) of the floor space used for multi-family residences shall be assessed at the rate of seven hundred ten dollars($710.00)per multi-family residence. iv. Other: For all other properties except City properties, 15.7 cents ($0.157) per square foot of property connected but not less than one thousand, one hundred eighty dollars ($1,180.00). v. Payment: Fees are incurred upon the granting by the City of a building permit or a construction permit, but are payable at the time construction inspection permits are issued for connection to or extension of the public water main; or in the absence of the requirement of a public works permit, then at the time of granting the building permit. All other water service applicants shall pay at the time the water meter application is issued. vi. Fees Upon Sale: Fees are due immediately if the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the City agrees that the third party shall be responsible for that fee after determining that such an agreement would be in the City's best interest. The burden of establishing that the agreement would be in the City's best interest would be on the party owing the fee and not on the City. vii. Definition: When the phrase "property which has not participated in development of the system"is used in this Section, it shall mean any of the following: 7 ORDINANCE NO. 487 2 • First Time Water Connection: Any property which has not paid a system development charge for the property based upon the square footage of the property and which is connecting to Renton's water system for the first time (including but not limited to new construction, or conversion from a private well). • Further Development or Subdivision: Any property which has not paid a system development charge for the property based upon the square footage of the property that is to be served by the utility and is developing or subdividing further. For example, one single family residence of a five (5) acre tract which has paid one thousand, one hundred eighty dollars ($1,180.00) under this Section to connect to a watersystem will have paid only for one, seven thousand five hundred(7,500) square foot lot at a rate of 15.7 cents ($0.157). Additional charges would be applied to any additional development on the property at the time of development. • Existing Developments: Property that was developed before the effective date of the first development charge ordinance in 1974 is exempted from the connection charge. Any rebuilding, change in use or additions to exempted property that does not require additional water usage such that a fire hydrant, larger meter or irrigation meter is necessary will not trigger a new connection charge. However, when property is redeveloped or the use changed or intensified such that a larger water meter or additional water meters or a fire hydrant are necessary, or when no water meter was obtained before, such as property on a well, then any application for the initial water meter or a larger water meter or installation of a fire hydrant will trigger a system development charge, except as provided herein. For the purposes of this policy, such property when applying for an initial or larger water meter or installing a fire hydrant or irrigation meter shall be property that has not been previously assessed. 8 ORDINANCE NO. 487 2 viii. Redevelopment Credit: An option exists for receiving a redevelopment credit for property which has not previously paid in full a system development charge. A redevelopment project that requires a larger water meter, or additional water meters, or a fire protection service for sprinklers, or a fire hydrant will trigger the water utility system development charge. However, any parcel that currently has water service is eligible for a prorated system development charge. This prorated redevelopment charge is based on the following formula: (Proposed domestic meter(s) capacity in gallons per minute—Existing domestic meter(s) capacity in GPM/Proposed domestic meter(s) capacity in GPM) x SDC Fee = Amount owed. Fire flow meters are not included in this calculation. For example, a redevelopment project that involves a change from a single family home on a ten thousand (10,000) square foot lot with a five-eighths inch by three-quarter inch meter (5/8" x 3/4", a standard single family meter) that has a safe operating capacity of twenty (20) gallons per minute (GPM),to a four (4) unit multi-family dwelling with a one and one-half inch (1-1/2") meter with a safe operating capacity of one hundred (100) GPM can apply to pay the following prorated charge: (100 GPM—20 GPM/100 GPM)x$1,570.00=$1,256.00 Without the redevelopment credit,this project would have paid 15.7 cents per square foot ($0.157/sq. ft.)x 10,000 sq. ft. =$1,570.00 The City will determine the safe maximum operating capacities of all meter sizes using American Water Works Association tables (see below). The fee paid shall be recorded and applied as a partial payment to the total system development charge applicable for the parcel. Reduction in meter capacity shall not result in a payment from the City to the applicant. 9 ORDINANCE NO. 4872 SECTION IV.

All other sanitary sewer service applicants shall pay these fees at the time of building sewer application. vi. Fees Upon Sale: Fees are due immediately if the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the City agrees that the third party shall be responsible for that fee after determination that such an agreement would be in the City's best interest. The 2 ORDINANCE NO. 4 8 7 5 burden of establishing the agreement would be on the party owing the fee and not on the City, and would be in the City's best interest. vii. Defuution: When the phrase "property which has not participated in development of the system" is used in this Section, it shall mean any of the following: •. First Time Server Connection: Any property which has not paid a system development charge for the property based upon the square footage of the property and which is connecting to Renton's sewer system for the first time (including but not limited to new construction, or conversion from septic system). • Further Development or Subdivision: Any property which has not paid a system development charge for the property based upon the square footage of the property that is to be served by the utility and is developing or subdividing further. For example, one single family residence on a five (5) acre tract which has paid seven hundred sixty dollars ($760.00) under this Section to connect to a sewer system will have paid only for one, seven thousand one hundred sixty-five (7,165) square foot lot at the rate of 10.6 cents ($0.106). Additional charges would be applied to any additional development on the property at the time of development. • Larger or Additional Water Meters: Any property which has not paid a system development charge for the property based upon the square footage of the property that is to be served by the utility and that requests or requires a larger or additional domestic water meter(s) will trigger a utility system development charge. • Redevelopment Credit: An option exists for receiving a redevelopment credit for property which has not previously paid in full a system development charge. A redevelopment project that requires a larger water meter, or additional domestic water meter(s), will trigger the sewer utility system development charge. However, any parcel that currently has water service is 3 ORDINANCE NO. 4 8 7 5 eligible for a prorated system development charge. This prorated development charge is based on the following formula: (Proposed domestic meter(s) capacity in gallons per minute (GPM) — Existing domestic meter(s) capacity in GPM/Proposed domestic meter(s) capacity in GPM) x SDC Fee = Amount owed. Fire flow meters are not included in this calculation. For example, a redevelopment project that involves a change from a single family home on a ten thousand (10,000) square foot lot with a five-eighths inch by three-quarter inch meter (5/8" x 3/4", a standard single family meter) that has a safe operating capacity of twenty (20) gallons per minute (GPM), to a four (4) unit multi-family dwelling with a one and one-half inch (1-1/2") meter with a safe operating capacity of one hundred(100) GPM can apply to pay for the following prorated charge: (100 GPM—20 GPM/100 GPM)= 0.8 0.8 x(10,000 sq. ft.x$0.106/sq. ft.)_$848.00 Without the redevelopment credit, this project would have paid $0.106/sq. ft. x 10,000 sq. ft. = $1,060.00. The City will determine the safe maximum operating capacities of all meter sizes using American Water Works Association tables (see subsection I.4.b(ix) of this Section). The fee paid shall be recorded and applied to the total system development charge applicable for the parcel. Reduction in water meter capacity shall not result in a payment from the City to the applicant. • Fire Protection Credit: Installation of a water meter solely for a fire protection system, such as a new hydrant or fire sprinkler system, shall not trigger a sewer system development fee. viii. Short-Term Use: Temporary connections to the City's sewage system may be granted for a one-time,temporary, short-term use of a portion of the property for a period not to 4 ORDINANCE NO. 4 8 7 5 exceed three (3) consecutive years. Permission for temporary connection may be granted upon payment of an annual fee equal to ten percent (10%) of the current system development charge applicable to that portion of the property, but not less than seven hundred fifty dollars ($750.00) per year. Said fee shall be paid annually (nonprorated), and shall be nonrefundable, nontransferable (from one portion of the property to another) and shall not constitute a credit to the system development charge due at the time of permanent use of the utility system. The application for temporary connection shall consist of a detailed plan and a boundary line of the proposed development service area for use in the fee determination. SECTION II. Section 4-1-180.I.3.b(i) through (v) of Chapter 1, Administration and Enforcement, of Title IV (Development Regulations) of Ordinance No. 4260 entitled "Code of General Ordinances of the City of Renton, Washington" is hereby amended as follows: i.

Issuance of Permits: Fees are incurred upon the granting by the City of a building permit, but are payable at the time construction permits are issued for connection to or extension of the public surface water collection system; or, in the absence of the requirement of a public works permit,then at the time of granting the building permit. iv. When Due: Fees are due immediately, notwithstanding subsection I.3.b(iii) of this Section, the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the 5 ORDINANCE NO. 4 8 75 City agrees that the third party shall be responsible for that fee after determining that such an agreement would be in the City's best interest. The burden of establishing that the agreement would be in the City's best interest would be on the party owing the fee and not on the City. v. Definition: When the phrase "property which has not participated in development of the system" is used in this Section, it shall mean any of the following: • First Time Surface Water Connection: Any property which has not paid a system development charge for the property based upon the square footage of new impervious surface of the property and which is connecting to Renton's surface water collection system for the first time(including but not limited to new construction). • Further Development or Subdivision: Any property which has not paid a system development charge for the property based upon the square footage of new impervious surface of property that is to be served by the utility and is developing or subdividing further. For example, one single family residence of a five (5) acre tract which has paid five hundred twenty-five dollars ($525.00) under this Section to connect to a surface water collection system will have paid only for one, seven thousand one hundred sixty-five (7,165) square foot lot at a rate of 18.3 cents ($0.183) per square foot of impervious area. Additional charges would be applied to any additional development on the property at the time of development. • Runoff Quantity Control: Any property for which one hundred percent (100%) of the surface water runoff quantity control requirements can be met by infiltration systems, as allowed by code,will be exempted from the surface water charge. • Existing Developments: Property that was developed before the effective date hereof is exempted from the connection charge. Any rebuilding, change in use or additions to exempted property that does not require additional surface water runoff capacity will not trigger 6 ORDINANCE NO. 4 8 7 5 a new connection charge. However, when property is redeveloped or the use changed or intensified such that a larger surface water drainage capacity is necessary, then any application for rebuilding will trigger a utility connection charge. "Surface water drainage capacity" is defined as computed maximum peak rate runoff from the site prior to entering public or private stormwater facilities. Improvements to existing single family residential units such as additions, decks, small sheds and other minor improvements are exempt from the system development charge unless a new connection to the Renton surface water utility collection system is proposed or required as part of the permit application. SECTION III. Section 4-1-180.I.4.b(i) through(viii) of Chapter 1, Administration and Enforcement, of Title IV (Development Regulations) of Ordinance No. 4260 entitled "Code of General Ordinances of the City of Renton, Washington" is hereby amended as follows: i. Single Family: One thousand, one hundred five dollars ($1,105.00) per single family residence. ii. Mobile/Manufactured Homes: Eight hundred eighty-five dollars ($885.00) per dwelling unit located in mobile home parks and manufactured home parks. iii. Multi-Family: Six hundred sixty-five dollars ($665.00) per multi-family residence, except in the Center Downtown (CD) and Center Office/Residential (COR) zoned areas which shall be assessed in accordance with subsection I.4.b(iv) of this Section. Mixed use buildings with over fifty percent (50%) of the floor space used for multi-family residences shall be assessed at the rate of six hundred sixty-five dollars ($665.00)per multi-family residence. iv. Other: For all other properties except City properties, 15.4 cents ($0.154) per square foot of property connected but not less than one thousand, one hundred five dollars($1,105.00). 7 ORDINANCE NO. 4 8 7 5 v. Payment: Fees are incurred upon the granting by the City of a building permit or a construction permit, but are payable at.the time construction inspection permits are issued for connection.to or extension of the public water main; or in the absence of the requirement of a public works permit, then at the time of granting the building permit. All other water service applicants shall pay at the time the water meter application is issued. vi. Fees Upon Sale: Fees are due immediately if the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the City agrees that the third party shall be responsible for that fee after determining that such an agreement would be in the City's best interest. The burden of establishing that the agreement would be in the City's best interest would be on the party owing the fee and not on the City. vii. Defmition: When the phrase "property which has not participated in development of the system" is used in this Section, it shall mean any of the following: • First Time Water Connection: Any property which has not paid .a system development charge for the property based upon the square footage of the property and which is connecting to Renton's water system for the first time (including but not limited to new construction, or conversion from a private well). • Further Development or Subdivision: Any property which has not paid a system development charge for the property based upon the square footage of the property that is to be served by the utility and is developing or subdividing further. For example, one single family residence of a five (5) acre tract which has paid one thousand, one hundred five dollars ($1,105.00) under this Section to connect to a watersystem will have paid only for one, seven thousand one hundred sixty-five (7,165) square foot lot at a rate of 15.4 cents ($0.154). 8 ORDINANCE NO. 4 8 7 5 Additional charges would be applied to any additional development on the property at the time of development. • Existing Developments: Property that was developed before the effective date of the first development charge ordinance in 1974 is exempted from the connection charge. Any rebuilding, change in use or additions to exempted property that does not require additional water usage such that a fire hydrant, larger meter or irrigation meter is necessary will not trigger • a new connection charge. However, when property is redeveloped or the use changed or intensified such that a larger water meter or additional water meters or a fire hydrant are necessary, or when no water meter was obtained before, such as property on a well, then any application for the initial water meter or a larger water meter or installation of a fire hydrant will trigger a system development charge,except as provided herein. For the purposes of this policy, such property when applying for an initial or larger water meter or installing a fire hydrant or irrigation meter shall be property that has not been previously assessed. viii. Redevelopment Credit: An option exists for receiving a redevelopment credit for property which has not previously paid in full a system development charge. A redevelopment project that requires a larger water meter, or additional water meters, or a fire protection service for sprinklers, or a fire hydrant will trigger the water utility system development charge. However, any parcel that currently has water service is eligible for a prorated system development charge. This prorated redevelopment charge is based on the following formula: (Proposed domestic meter(s) capacity in gallons per minute—Existing domestic meter(s) capacity in GPM/Proposed domestic meter(s) capacity in GPM) x SDC Fee = Amount owed. Fire flow meters are not included in this calculation. 9 ORDINANCE NO. 4 8 7 5 For example, a redevelopment project that involves a change from a single family home on a ten thousand (10,000) square foot lot with a five-eighths inch by three-quarter inch meter (5/8" x 3/4", a standard single family meter) that has a safe operating capacity of twenty (20) gallons per minute (GPM),to a four (4) unit multi-family dwelling with a one and one-half inch (1-1/2") meter with a safe operating capacity of one hundred (100) GPM can apply to pay the following prorated charge: (100 GPM—20 GPM/100 GPM)x$1,540.00=$1,232.00 Without the redevelopment credit,this project would have paid 15.4 cents per square foot ($0.154/sq. ft.)x 10,000 sq. ft._$1,540.00 The City will determine the safe maximum operating capacities of all meter sizes using American Water Works Association tables (see below). The fee paid shall be recorded and applied as a partial payment to the total system development charge applicable for the parcel. Reduction in meter capacity shall not result in a payment from the City to the applicant. SECTION IV. This ordinance shall be effective upon its passage, approval, and 30 days after publication.

An RMC chapter should be cited chapter 4-10 RMC. An RMC section should be cited RMC 4-10-010. Through references should be made as RMC 4-10-010 through 4-10-040. Series of sections should be cited as RMC 4-10-010, 4-10-020, and 4-10-030. Page and section numbering system: The page numbering system for these regulations does not run sequentially from the first page of the document to the last. Instead, page numbering begins with the number of the chapter followed by a page number. Each chapter starts with a Table of Contents listing the provisions found in the chapter by page number. These Table of Contents pages themselves are numbered with lowercase Roman numerals. For example, the first page of the Table of Contents of the first chapter is 1-i; the first page of text of the first chapter is 1-1; the tenth page is 1-10. The first page of the Table of Contents of the second chapter is 2-i; the first page of text is 2-1, and so on to the end of the document. As the Development Regulations are supplemented and pages are added, a decimal numbering and lettering system is used to allow for expansion of existing chapters. A detailed directions page is included with each supplement. The section numbering system used in the Development Regulations operates in the following manner: 4 — 10 010 Al a(i) in subsect o s section of chapter chapter of title title of Renton Municipal Code Legislation: The legislative source of each section is enclosed in parentheses at the end of the applicable section or subsection. References to ordinances are abbreviated and a semicolon between ordinance citations indicates an amendment of the earlier section; thus "(Ord. 4638, 4-4-94; Amd. Ord. 4654, 6-5-94)" refers to Ordinance No. 4638 as amended by Ordinance No. 4654. Index: The Development Regulations index follows Chapter 4-11. The index includes com- plete cross-referencing and is keyed to the section and subsection numbers described above.

CONSIDERATIONS ON SELECTION OF PIPE MATERIALS The Utility maintains a list of materials meeting performance standards. Other materials meeting similar performance standards or developed as the result of new technology may be approved by the Utility. a. Rubber gaskets may be severely damaged by petroleum products,particularly in prolonged exposures to concentrated flows containing little or no storm water or sanitary sewage. In cases where heavy concentrations of petroleum products may be experienced,nitrite (Nitrile-Butadiene;i.e., NBR)gaskets should be used. b. Gasketed joints may not be leak-proof at zero or low pressures, if improperly installed. c. Mechanical joints may be less likely to leak at low pressures than push-on joints. ct,. d. May need protective coatings and/or cathodic protection against external corrosion. e. Considered most reliable gasket and lining material for ductile iron leachate pipeline. f. Very difficult to repair linings on inside of joints in pipe smaller than 24-inch diameter. g. Almost always needs protective coatings and cathodic protection against external corrosion. h. Properly made joints are considered leak-proof. i. Nitrile gaskets may require long delivery time. j. Requires special attention to bedding and backfill depth to avoid structural failure of pipe. 3 -20.55 (Revised 10/00) 4-3-050S k. Large thermal expansion coefficient.May need to limit solvent welded joints to 4-inch and smaller pipe. May require careful evaluation of pipe installation temperature and temperature of piped liquids to ensure joint integrity. I. Pipe not available over 12-inch diameter. 4' m. Slip form lining is available in 6-inch through 60-inch diameter for almost any pressure,if sufficient pipe cross- sectional area is available. n. Pressure grouts and gels are not acceptable for rehabilitation or patching of storm and sanitary sewers. o. Suitability of pipe lining and gasket material to resist chemical attack by conveyed fluids must be determined for each pipeline service considered. p. All storm and sanitary sewer manholes,catch basins,and inlets should be equipped with precast concrete bottom and sidewalls with rubber gasketed joints between sections,water-tight epoxy grout or other approved pipe entrances through walls,and approved waterproof coating of all interior floor and wall surfaces. Manholes,catch basins,and inlets should have no leakage when hydrostatically tested at atmospheric pressure. q. Has good resistance to a number of chemicals,petroleum products,and hydrogen sulfide corrosion. r. "Zero leakage"test requirement may be impossible to achieve under the best conditions for any pipe materials because trapped air may distort test results,even in a drop-tight pipe. Pressure and leakage test requirements should consider whether the pipe has steel slope or will stand full of liquid. Pipelines should be tested with the intent to prevent or minimize leakage.Air testing should not be allowed;hydrostatic testing should be as stringent as any found in the industry. Pipe materials,without regard for chemical attack,corrosion, or puncture,are generally ranked as follows, in decreasing order of liquid-tight reliability: • welded steel with welded joints • PVC with solvent welded joints • slip form liner • ductile iron with viton or rubber gaskets • welded steel with rubber gasketed joints • PVC with viton or rubber gasketed joints s. Joints should consist of"heat-shrink"wrap,standard corrugated coupling,and full pipe band clamps. t. The use of PVC may be restricted by other Utility policy in regards to depth of pipe cover. u. HDPE may be adversely affected by solvents;its use is not recommended where contact with solvents may occur. (Ord. 4851, 8-7-2000) (Revised 10/00) 3-20.56 4-3-090B 4-3-060 (Reserved) C.

Increase recreational opportunities for the public in the shoreline. E. REGULATED WATER BODIES: Approximately eighteen (18) miles of shoreline in the City of Renton are under the jurisdiction of the Shoreline Management Act of 1971. These eigh- teen (18) miles of shoreline in the City of Renton are considered an extremely valuable resource not only to the City of Renton,but also to the State Metropolitan Area of which Renton is an integral part. In the City of Renton,the following bodies of water are regulated by the Act: 1. Cedar River. 2. Green River. (Revised 10/00) 3 -20.58 4-3-090G Lake Washington are classified as Shorelines of Statewide Significance, and comprise ap- proximately 5.8 miles of the shorelines of the State regulated by the City of Renton. 2. Shorelines of the State: In addition,the shorelines of the Cedar River, Black River, Springbrook Creek, and May Creek are shorelines within the City. G. THREE (3) ENVIRONMENTS DESIGNATED BY CITY: 1. Names of Environments: Three(3) en- vironments, Natural, Conservancy, and Ur- ban,shall be designated to provide a uniform basis to apply policies and use regulations within distinctively different shoreline areas. 2. Basis for Designation: The environ- mental designation to be given any specific area shall be based on the existing develop- ment pattern,the biophysical capabilities and limitations of the area being considered for development and the goals and aspirations of • local citizenry. Shorelines have been catego- rized according to the natural characteristics and use regulations have been designated herein. 3.
