III. REVIEW PROCESS The proposed action is subject to State Environmental Policy Act (SEPA) review as the project does not meet the exemptions listed under WAC 197 -11 -800. IV. BACKGROUND /PROPOSAL The project is on a manufacturing site for the Boeing Company. Building 2 -10 extends over a portion of the shoreline on the lower Duwamish waterway, supported by wood piles. The proposal is for replacement of armoring to the river bank that has subsided over the years. Two industrial storm drains are located beneath the building. The armoring would occur beneath the two industrial storm drains located beneath Boeing Building 2 -10. Armoring consists of 165 cubic yards of light, loose riprap on top of filter fabric confined to the footprint of the existing armoring and is considered normal maintenance. The riprap would be hand - placed during low tide and no in -water work would occur. Additional, the project proposes to extend one of the two storm drains by nine feet to extend the outfall beyond the shoreline in order to prevent erosion of the shoreline during discharge events. V.

The proposed project will involve the maintenance of existing armoring protecting two permitted stormwater outfalls discharging to the Duwamish River. It is our understanding and would like your concurrence that a Substantial Development permit is not required for projects involving "normal maintenance and repair." I am trying to determine what permits are required for the proposed project and whether a State Environmental Policy Act (SEPA) review will be required. ..The proposed project location is at 1 135 S Webster Street, Tukwila, Washington, on The Boeing Company property (Figure 1). The property is used by Boeing in manufacturing commercial aircraft. Building 2 -10 is located on the project site adjacent to the east bank of the Duwamish River (Figure 1). The areas surrounding Building 2 -10 are paved and used for parking. A portion of Building 2 -10 extends over the shoreline on the Duwamish River and is supported by wood piles. The shoreline beneath the building is riprapped. Two permitted storm drains (Drains F & G: Ecology Permit No. S03- 000482) draining roof runoff are located beneath the building and discharge to the Duwamish River. Existing riprap armoring used to protect the bank and piling has been displaced over the years through wave and current action (Figures 2, 3, and 4), exposing the bank and piling to potential damage from additional wave and current action. Under the proposed plan, light, loose riprap would be replaced around each of the storm drains to protect them from damage. A total of 165 cubic yards of riprap (115 cubic yards at Outfall F and 50 cubic yards at Outfall G) would be hand - placed during low tide events so that no in -water work would be necessary (Figures 5, 6, and 7). Riprap would be transported to the outfalls in wheelbarrows using an existing wooden walkway beneath the building (Figure 5) and replaced by hand and hand tools only. No in -water 3500 188th Street SW, Suite 600 Lynnwood, Washington 98037 -4763 Tel (425) 921 -4000 Fax (425) 921 -4040 www.geomatrix.com • • Ms. Minnie Dhaliwai City of Tukwila Department of Community Development April 21, 2008 Page 2 work will occur and no motorized vehicles or vessels will be used waterward of the ordinary high water mark. The riprap to be replaced will be confined to the footprint of the existing armoring. Additionally, at Outfall G, nine (9) feet of 10 -inch SDR 35 PVC pipe will be added to the existing storm drain using a Fernco Coupler to extend the outfall pipe beyond the shoreline to prevent erosion of the shoreline during discharge events (Figures 6 and 8). Support bracing for the outfall extension will be anchored to the overhead concrete deck (Figure 8). No in -water work will be conducted to complete this portion of the project. I trust that I have provided sufficient detail in describing the proposed project for you to make a determination of what permitting will be required.

Box 3707, MC 1W-09 Street Address: Seattle, WA 98124 -2207 City, State, Zip: (206) 617 -2944 Telephone: Directions This Screening Checklist has been designed to evaluate the potential for your project to result in potential "take" of Chinook salmon, Coho salmon, or Cutthroat trout as defined by Section 9 of the Endangered Species Act. The checklist includes a series of "Yes" or "No" questions about your project, organized into four parts. Starting with Part A on Page 1, read each question carefully, circle "Yes" or "No," and proceed to the next question as directed by the checklist. To answer these questions, you may need to refer to site plans, grading and drainage plans, critical areas studies, or other documents you have prepared for your project. The City will evaluate your responses to determine if "take" is indicated.. f Part A: Please review and answer each question carefully. Consider all phases of your project including, but not limited to, construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -0 Will the project require any form of grading? Grading is defined as any excavating, filling, clearing, or creation of impervious surface, or any combination thereof, which alters the existing ground surface of the earth (TMC 18.06.370). Please circle appropriate response. NO F Continue to Question 2 -0 YES - Continue to Question 1 -1 (Page 3) 2 -0 Will the project require any form of clearing? Clearing means the removal or causing to be removed, through either direct or indirect actions, any vegetation from a site (18.06.145). • Please circle appropriate response. NO - Continue to Question 3 -0 YES - Continue to Question 2 -1 (Page 4) 3 -0 • Will the project require work, during any time of the project, below the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high water mark is the mark that is found by examining the bed and banks of a stream and ascertaining where the presence and action of waters are so common and usual as to distinctly mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06, Page 18 -15). Please circle appropriate response. NO - Continue to Question 4 -0 IYESI - Continue to Question 3 -1 (Page 5) 4 -0 Will the project result in the processing or handling, storage, or treatment of hazardous substances? This does not include the proper use of fuel stored in a vehicle's fuel tank. Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria of hazardous waste as defined by Washington Administrative Code 173 -303 (TMC 18.06.385). This includes fuel or other chemicals stored on -site during construction. Please circle appropriate response. NO - Continue to Question 5 -0 YES - Continue to Question 5 -0 5 -0 Will the project result in the withdrawal, injection, or interception of groundwater? Examples of projects that may affect groundwater include, but are not limited to: construction of a new well, change in water withdrawals from an existing well, projects involving prolonged construction dewatering, projects installing French drains or interceptor trenches, and sewer lines. For the purpose of this analysis, projects that require a geotechnical report pursuant to the requirements of TMC 18.45.060 or would require a geotechnical report if not exempt should answer Yes. Please circle appropriate response. NOI - Continue to Question 6 -0 YES - Continue to Question 6 -0 City of Tuk*ESA Screening Checklist Part A (continued) 6 -0 Will the project involve landscaping or re- occurring outdoor maintenance that includes the regular use of fertilizers, pesticides, or herbicides? This does not include the one -time use of transplant fertilizers. Landscaping means natural vegetation such as trees, shrubs, groundcover, and other landscape materials arranged in a manner to produce an aesthetic effect appropriate for the use of the land (TMC 18.06.490). For the purpose of this analysis, this includes the establishment of new lawn or grass. Please circle appropriate response. NO I- Checklist Complete YES — Checklist Complete Part B: Please answer each question below for projects that include grading. Review each question carefully, considering all phases of your project including, but not limited to construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 -1 Will the project involve the modification of a watercourse bank or bank of the Green/Duwamish or Black Rivers between the ordinary high water mark and top of bank? This includes any projects that will require grading on any slope leading to a river or stream, but will not require work below the ordinary high water mark. Work below the ordinary high water mark is covered in Part C. Please circle appropriate response. NO - Continue to Question 1 -2 YES - Continue to Question 1 -2 1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and /or sedimentation in watercourses, the Green /Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and /or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 1 -3 YES - Continue to Question 1 -3 1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development. Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or . other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development (TMC 18.06.445). Please circle appropriate response., NO - Continue to Question 2 -0 (Page 2) YES - Continue to Question 1 -4 • City of Tuk•ESA Screening Checklist Part B (continued) 1 -4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater treatment and management system intended to contain all stormwater on site by allowing it to seep into pervious surface or through other means to be introduced into the ground. If your project involves the construction of impervious surface and does not include the design of a stormwater management system specifically designed to infiltrate stormwater, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 2 -0 (Page 2) YES - Continue to Question 2 -0 (Page 2) Part C: Please review each question below for projects that include clearing. Review each question carefully, considering all phases of your project including, but not limited to construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 2 -1 Will the project involve clearing within 200 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? Please circle appropriate response. NO - Continue to Question 3 -0 (Page 2) YES - Continue to Question 2 -2 2 -2 Will the project involve clearing of any trees within 200 feet of the ordinary high water mark of a watercourse or the Green /Duwamish or Black Rivers? A tree is defined by TMC 18.06.845 as any self - supporting woody plant, characterized by one main trunk, with a potential diameter - breast- height of 2 inches or more and potential minimum height of 10 feet. Please circle appropriate response. NO - Continue to Question 2 -3 YES - Continue to Question 2 -3 2 -3 Will the project involve clearing of any evergreen trees from within 200 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis evergreen means any tree that does not regularly lose all its leaves or needles in the fall. Please circle appropriate response. NO - Continue to Question 2 -4 YES - Continue to Question 2 -4 2 -4 Will the project involve clearing within 100 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers?

The project site is located at approximately River Mile 3.1. The proposed project is necessary as part of the normal maintenance to replace armoring that has subsided over the years. The armoring needs to be replaced to provide continued protection of the storm drains. One of two permitted storm drains (Outfall G) needs to be extended farther. away from the shoreline to prevent shoreline erosion during discharge events and to prevent discharge from the storm drain from eroding the shoreline beneath the armoring once it has been replaced. A portion of Bldg. 2 -10 extends over the shoreline on the lower Duwamish Waterway (LWD) and is supported by wood piles. Two permitted industrial storm drains (Outfalls F & G: Ecology Permit No. SO3- 000482) are located beneath Bldg. 2 -10 and are used to drain roof runoff. Existing riprap armoring used to protect the storm drains has subsided over the years (Figures 3, 4, and 5). Under the proposed action, light, loose riprap would be replaced around each of the storm drains to provide continued protection. Filter fabric mat would be placed on the substrate and then the riprap would be placed by hand on top of the filter fabric mat. A total of 165 cubic yards of riprap (115 cy at Outfall F and 50 cy at Outfall G) would be hand placed during low tide events so that no in -water work would be necessary (Figures 6, 7, and 8). Riprap would be transported to the outfalls in wheelbarrows using an existing wooden walkway beneath the building (Figure 6) and replaced by hand and hand tools only. No in -water work will occur and no motorized vehicles or vessels will be used waterward of the ordinary high water mark. Replacement riprap would be confined to the footprint of the existing armoring. Riprap will be placed over a total of 1,252 square feet (Outfall F = 904 square feet and Outfall G = 348 square feet). Additionally, at Outfall G, nine (9) feet of 10 -inch SDR 35 PVC pipe will be added to the existing culvert using a Fernco Coupler to extend the outfall pipe beyond the shoreline to prevent erosion of the shoreline during discharge events (Figures 7 and 9). Support bracing for the outfall extension will be anchored to the overhead concrete deck (Figure 9). No in -water work will be conducted to complete this portion of the project.
