PROJECT DESCRIPTION L04 -017 - Shoreline Permit August 10, 2004 The project replaces approximately 1,200 lineal feet of undersized stormwater main in Strander Blvd. from Andover Parkway East to the Green River outfall with 24 -to 36- inch diameter pipe. The project includes a below grade stormwater pump station in the Christensen Road right of way adjacent to Bicentennial Park and restoration (grinding and ACP overlay) of the roadway within the project limits. In the process, private storm drains will be reconnected, right of way catchbasins will be replaced, and the existing outfall will be abandoned. The normal mode of the proposed stormwater system will oe gravity flow to the river via the relocated outfall, and the pumps will be utilized to maintain flows and avoid upstream flooding. The project includes construction of the outfall pipe through the flood control levee and restoration of the levee. H. FINDINGS The site is within the jurisdiction of the Tukwila Shoreline Master Program (SMP). This program was adopted in June 1974 and amended on March 16, 1982. The City's SMP was reviewed and approved by the State Department of Ecology as being consistent with the State Shoreline Management Act, adopted in 1971. All shorelines are designated urban. The Shoreline Master Plan establishes three management zones adjacent to the Green/Duwamish River: River Zone: This zone includes the first 40 feet from the mean high water mark. Low Impact Zone: This zone includes the second 60 feet from the mean high water mark. High Impact Zone: This zone includes the area from 100 feet to 200 feet from the mean high water mark. 2 Following are the relevant review criteria as contained in the Tukwila Shoreline Regulations (Tukwila Municipal Code, Chapter 18.44) as applied by the City of Tukwila. Shoreline Substantial Development Permit (18.44.80) Any substantial development within 200 feet of any shoreline must receive a shoreline substantial development permit prior to issuance of any local permits by the City. The project replaces undersized stormwater main to the Green River outfall with 24 -to 36 -inch diameter pipe and includes a below -grade stormwater pump and restoration (grinding and ACP overlay) of the roadway within the project limits. Private storm drains will be reconnected, right of way catchbasins will be replaced, and the existing outfall will be abandoned. The project includes construction of the outfall pipe through the flood control levee and restoration of the levee. The project area is located within 200 feet of the Mean High Water Mark (MHWM) of the Duwamish/Green River and is subject to shoreline substantial development permit. General Shoreline Regulations (18.44.110) 3 L04 -017 - Shoreline Permit August 10, 2004 1. The use is in conformance with the regulations of the underlying zone district; The project location is in the Tukwila Urban Center zone, and the use is in conformance with the regulations of the underlying zone district. The proposed project is a stormwater utility project in public road right -of -way with very minor drainage replacement on private parking lots and a segment of pipeline through Bicentennial Park. The project replaces the existing stormwater conveyance and adds a below grade pump station. 2. The use does not conflict with the goals and policies of the shoreline master program or the provisions of the Shoreline Act and shoreline regulations; The use is consistent with the goals and policies of the shoreline master program and the provisions of the Shor }line Act and shoreline regulations. The project will not reduce public access to the shoreline or impact use of Bicentennial Park when completed. The project enhances water quality in the Green River by providing sediment and floatables removal before discharging to the river. The purpose of the project is to enhance public safety by reducing flooding in Strander Blvd. 3. No structures or accessory facilities shall be located over the river unless such structure protects or promotes the public interest; No structures or accessory facilities will be located over the river. S L04 -017 - Shoreline Permit August 10, 2004 4. There shall be no disruption of existing trees or vegetation within the river environment unless necessary for public safety or flood control, or if allowed as part of an approved shoreline substantial development permit; Construction of the outfall will require removal of grasses, blackberries, and organic topsoil at the levee. These will be replaced with topsoil and seeded grasses after reconstruction of the outfall and levee complete. A native grass mix will be planted post - construction to reduce erosion and willow plantings will be utilized for habitat enhancement. Shoring will be used to limit the trench width near a 20 -inch tree adjacent to the pump station in the Park, which is the best approach for avoiding damage to the tree. No endangered plant species are known to be on the site. S. No effluent shall be discharged into the Green River which exceeds the water quality classification as established by the State for the adjacent portion of the river; Construction measures to reduce impacts to surface, ground and runoff water include the use of best management practices and erosion control measures in accordance with the State of Washington Department of Ecology's Stormwater Management Manual for Western Washington. When construction is complete, waste materials are unlikely to enter ground or surface waters. Since it is possible that waste materials could enter surface waters through careless construction methods or practices due to the proximity of the discharge and outfall work to the river, mitigation measures and/or best management practices should be employed to minimize waste materials entering the river. The proposed outfall will replace an existing stormwater outfall, with no anticipated change in existing basin characteristics or stormwater quantity. The project adds sediment and floatables removal measures to the conveyance system, thereby enhancing the existing stormwater quality being discharged to the River from this basin. 4 .,a 7. Wildlife habitat in and along the river shall be protected; 9. All necessary permits shall be obtained from federal, State, County or municipal agencies; A determination of Non Significance was issued on May 17, 2004. 5 L04 -017 - Shoreline Permit August 10, 2004 6. All State and federal water quality regulations shall be strictly complied with; The existing storm drainage will be repaired and up„Traded and will continue to collect storm water and direct it into the existing storm drainage system. A temporary erosion and sediment control plan consistent with requirements of the King County Surface Water Design Manual was prepared to reduce sediment transport offsite during construction. The plan includes construction staging to limit outfall work to low summer flows, installation of sediment traps in catch basins, restoration of the levee slope above the OHW consisting of coir fabric and meadow grass seeding, and installation of a silt fence across the toe of the restored levee area. Requirements and conditions of the Hydraulic Project Approval (HPA) permit will assure that wildlife habitat along the river is protected. The project occurs in a fairly featureless reach of the River where the levee is riprapped and covered with blackberries. The outfall design includes placement of two root wads below the ordinary high water mark for fish habitat enhancement. 8. All perimeters of landfills and other land forms susceptible to erosion shall be provided with vegetation, retaining walls, or other satisfactory mechanisms for erosion prevention; After installation of the outfall, the existing riprap on the levee slope will be replaced and augmented as necessary to protect the slope from erosion by eddies and the piped discharge. After the levee is reconstructed, the slope will be reseeded with meadow grasses covered with coir fabric. The following permits are anticipated: • City of Tukwila Plan Review, Clearing and Grading Permit, Building Department review and permit • Joint Acjuatic Resource Permit (JARPA) • Army Corps of Engineers, Nationwide Permit #7 Review • Approval from National Marine Fisheries Service (NMFS) • King County Flood Control District Approval • Hydraulic Project Approval (HPA) permit L04 -017 - Shoreline Permit August 10, 2004 Comments were received from the State Office of Archaeology and Historic Preservation. 10. Dredging for purposes other than for navigational improvements or flood control is prohibited; No dredging is included in this project. 11. Mining is prohibited along the river shoreline; No mining is included in this project. 12. Solid waste disposal is prohibited along the shoreline; No solid waste is disposed of as part of this project. 13. No property will be acquired for public use without dedication by or just compensation to the owner; This project is located on public right of way and in a City park; no dedications are required. 14. Landfilling is prohibited within the river channel, unless such landfill is determined by the Planning Commission to protect or promote the public interest. This project does not propose any landfilling within the river channel. 15. Notwithstanding any provisions of this Code to the contrary, removal of any cottonwood tree within the river environment or the low impact environment, which tree is 12 inches or greater in diameter as measured 4.5 feet above grade, shall be subject to the requirements of TMC Chapter 18.54, Tree Regulations. No removal of cottonwood trees is proposed for this project. Specific Shoreline Regulations -River Environment A.

COMMENTS In response to the notice of application, written comments (dated May 4, 2004) were received from Stephenie Kramer, State of Washington Office of Archaeology and Historic Preservation (OAHP). Ms. Kramer noted that there is a recorded archaeological site within three quarters of a mile of the project area as well as several ethnographic places names (one of which indicates a possible village location). OAHP therefore recommended a professional archaeological survey of any excavated sites associated with the pr .iject as well as consultation with concerned tribes' culturalbcommittees and staff regarding cultural resources issues. OAHP noted that if any federal funds or permits are involved, Section 106 of the National Historic Preservation Act and the Act's implementing regulations, 36CFR800, must be followed. OAHP requested that they be sent any correspondence or comments received by the City of Tukwila from concerned parties or tribes concerning cultural resource issues. 10 L04 -017 - Shoreline Permit August 10, 2004 Per a memorandum from Ryan Larson (dated May 7, 2004), the City stated that no federal funds are being used for the project and that it does not plan to conduct an archaeological survey as a part of the project because all work will be done in previously developed areas. The City also stated that it is not practical to conduct an exploratory excavation due to the anticipated excavation depths and location within open roadways. Mr. Larson affirmed that the contractor will be told to suspend construction if archaeological resources are encountered during work on the project and that the City will follow all necessary state and federal regulations, including notifying the OAHP in the event that archaeological resources are found. In an e -mail dated May 11, 2004, Ms. Kramer agreed with the contents of the above - mentioned May 7 memo but requested that an archaeological monitor be present during excavation work until glacial deposits or glacial clay is reached, to which the City agreed. IV. RECOMMENDATION Approval of the application subject to the following conditions: 1. A provision will be added to the contract requiring that all contract excavation activities will be stopped and the State Office of Archaeology and Historic Preservation will be notified if any artifacts are encountered during any of the excavation activities. 2. An Archaeologist will be required to be on site during the excavation for the pump station, until glacial deposits or glacial clay is reached. Prepared by: Tara Ballentine Date: August 10, 2004. July 21, 2005 Ms. Nora Gierloff Department of Community Development 6300 Southcenter Blvd., Suite 100 Tukwila, WA 98188 Subject: Tree Clearing Permit Strander Boulevard Stormwater Pump Station #17 Road and Drainage Improvements Dear Ms. Gierloff: The City is currently constructing the subject project that includes a new stormwater conveyance pipe through a section of Bicentennial Park. The Contractor has brought it to our attention that an existing tree within the park will need to be removed to allow for the pipe trench and large equipment to perform this work. This tree is approximately 140' from the Green River and therefcre is within the shoreline zone. Moving the pipe further from the tree is not a viable option because of the existing park restroom building that is on the other side of the planned pipe. An arborist reviewed the tree and trenching near the base of the tree and recommended that the tree be removed (letter attached). We are working closely with the Parks Department on this matter and they have requested that the tree be replaced when the project is completed. The required tree replacement ratio for a 24 -inch diameter tree is six new trees with a minimum diameter of 2.5 inches. The tree to be removed is part of the landscaping of the park and the addition of five trees within the park is not desirable. To meet the intent of TMC 18.54.050 requirements, the Public Works Department is proposing the following action: 2. Install a total of 250 willow stakes adjacent to the new stormwater outfall on the Green River levee (planting detail attached). These plantings are not currently required as part of this contract and are now being proposed to mitigate the subjects tree's removal. Thank you for your time regarding this issue.

Box 226 Issaquah, WA 98027 RE: Maple @ Centennial Park To Whom It May Concern: I was asked by Al Christian of Frank Coluccio Construction to inspect the Maple tree (Acer pseudoplatanus) located adjacent to the paved trail at Centennial Park, and determine if it would survive the construction activity. I visited the site Wednesday July 13, 2005. This concludes my report. Please contact me for clarification of its contents.

Box 226 Issaquah, WA 98027 Friday, July 15, 2005 Tree Evaluation The tree being evaluated is an Acer pseudoplatanus measuring 24" diameter at DBH, located at the entrance to the park adjacent to the path. It is my determination that the proposed trench to be located to the south, within 3' of the tree will sever approximately 50% of the tree's root mass. This amount of root loss will not only severely weaken the ability for the tree to maintain its anchor, but the tree will loose enough root mass that it will not be able to recover from it, leading to decay and eventual loss of the tree. Due to the size of the equipment needed to accomplish the trenching several of the largest branches would need to be removed, this would also severely affect the trees over all health. It is my recommendation that this tree be removed. Memo to File From: Minnie Dhaliwal This additional scope of work, which included removal of one maple tree with additional plantings of 250 willow stakes adjacent to the Green River was approved and was considered within the scope and intent of the original permit as allowed under WAC 173 -27 -100.

No structure or accessory facilities shall be located over the river: Strander Boulevard Stormwater Pump Station, Road, and Drainage Improvements City of Tukwila Shoreline Permit Submittal Criteria for Projects Subject to City of Tukwila Shoreline Regulations 1. Use is in conformance with regulations of the underlying zone district: The zone is Tukwila Urban Center. The proposed project is a stormwater utility project in public road right of way, with very minor drainage replacement on private parking lots, and a segment of pipeline through Bicentennial Park. The project replaces the existing stormwater conveyance and adds a below grade pump station. The purpose of the project is to enhance public safety by reducing flooding in Strander Blvd. The project enhances public safety in the area by reducing flooding in Strander Blvd. 2. Use does not conflict with the goals and policies of the Shoreline Master Program or the provision of the Shoreline Act and shoreline regulations: Project replaces an existing stormwater conveyance system, including abandoning the existing outfall to the Green River, and building a new outfall at a location about 450 feet to the north. The project will not reduce public access to the shoreline or impact use of Bicentennial Park when completed. The shoreline components within 200 feet of the shoreline are the outfall at the river, the below grade pump station at Christensen Road, expansion of the existing restroom for electrical panels, and below grade pipes. The project enhances water quality in the Green River by providing sediment and floatables removal before discharging to the river. No structures or accessory facilities are planned over the river. A below grade pump station will be built in Christenen Road, and electrical controls will be located in an 8 by 20 foot addition to the nearby existing restroom in Bicentennial Park. 4. No disruption of existing trees or vegetation within the river environment unless necessary for public safety or flood control, or if allowed as part of an approved Shoreline Substantial Development permit: Construction of the outfall will require removal of grasses, blackberries, and organic topsoil at the levee. These will be replaced with topsoil and seeded grasses after reconstruction of the outfall and levee is complete. One 20 -inch tree in the Park near the pump station is adjacent to the trench excavation where shoring will be used to limit the trench width, and be the best approach to not damaging the existing tree. 5. No effluents shall be discharged into the Green River which exceeds the water quality classification as established by the State for the adjacent portion of the river: The proposed outfall will replace an existing stormwater outfall, with no anticipated change in existing basin characteristics or stormwater quantity. The project adds sediment and floatables removal measures to the conveyance system, thereby enhancing the existing stormwater quality being discharged to the River from this basin. did' Strander Boulevard Stormwater Pump Station, Road, and Drainage Improvements City of Tukwila Shoreline Permit Submittal Criteria for Projects Subject to City of Tukwila Shoreline Regulations All State and Federal water quality regulations shall be strictly complied with: 7. Wildlife habitat in and along the river should be protected: Page 2 03/23/04 A temporary erosion and sediment control plan consistent with requirements of the King County Surface Water Design Manual was prepared to reduce sediment transport offsite during construction. The plan includes construction staging to limit outfall work to low summer flows, installation of sediment traps in catch basins, restoration of the levee slope above the OHW consisting of coir fabric and meadow grass seeding, and installation of a silt fence across the toe of the restored levee area. Requirements and conditions of the HPA permit will assure that wildlife habitat along the river is protected. The project occurs in a fairly featureless reach of the River where the levee is riprapped and covered with blackberries. The outfall design includes placement of two root wads below the ordinary high water mark for fish habitat enhancement. 8. Perimeters of landfills or other land forms susceptible to erosion should be provided with vegetation, retaining walls, or other satisfactory mechanisms for erosion prevention: After installation of the outfall, the existing riprap on the levee slope will be replaced and augmented as necessary to protect the slope from erosion by eddies and the piped discharge. After the levee is reconstructed, the slope will be reseeded with meadow grasses and covered with coir fabric. 9. All necessary permits shall be obtained from Federal, State, County or Municipal agencies: The following permits are anticipated: City of Tukwila Plan Review, Clearing and Grading Permit, Building Department review and permit Shoreline Permit Joint Aquatic Resource Permit (JARPA) Army Corps of Engineers, Nationwide Permit #7 Review Approval from National Marine Fisheries Service (NMFS) King County Flood Control District Approval 10.

SOME WOOD FIBER WITH VERY LONG FIBERS CAN BE EFFECTIVE AT LOWER APPUCATION RATES AND WITHOUT SEED OR TACKIFIER COMPOST NO VISIBLE WATER CR DUST DURING HANDLING. MUST BE PURCHASED FROM SUPPLIER WAN SOLI) WASTE HANDLING PERMIT. 2' THICK MIN.; APPROX. 100 TONS PER ACRE (APPROX. 800 LBS PER YARD) MORE EFFECTIVE CONTROL CAN BE OBTAINED BY INCREASING THICKNESS TO 3'. EXCELLENT MULCH FOR PROTECTING FINAL GRADES UNTIL LANDSCAPING BECAUSE IT CAN BE DIRECTLY SEEDED OR TILLED INTO SOIL AS AN AMENDMENT. SOURCES FOR COMPOST ARE AVAILABLE FROM KING COUNTY COMMISSION FOR MARKETING RECYCLABLE MATERIALS AT (206) 296 -4439. CHIPPED SITE VEGETATION AVERAGE SIZE SHALL BE SEVERAL INCHES. 2' MINIMUM THICKNESS THIS IS A COST - EFFECTIVE WAY TO DISPOSE OF DEBRIS FROM CLEARING AND GRUBBING. AND IT ELIMINATES THE PROBLEMS ASSOCIATED WITH BURNING. GENERALLY. IT SHOULD NOT BE USED ON SLOPES ABOVE APPROX. 10% BECAUSE CF ITS TENDENCY TO BE TRANSPORTED BY RUNOFF. IT IS NOT RECOMMENDED WITHIN 200 FEET OF SURFACE WATERS IF SEEDING IS EXPECTED SHORTLY AFTER MULCH. THE DECOMPOSITION OF THE CHIPPED VEGETATION MAY TIE UP NUTRIENTS IMPORTANT TO GRASS ESTABLISHMENT. D.10.4 CONSTRUCTION SEQUENCE A DETAILED CONSTRUCTION SEQUENCE IS NEEDED TO ENSURE THAT EROSION AND SEDIMENT CONTROL MEADS ARE APPLIED AT THE APPROPRIATE TIMES.
