(RCW 43.21C.075) STAFF EVALUATION FOR ENVIRONMENTAL CHECKLLIST George Long Shops Oil/Water Separator & Outfall Improvements File #: E08 -018 Summary of Proposed Action The Tukwila Public Works Department proposes to make improvements to the City shops facility, including: 1) installation of a wash pad connected to an oil/water sewer and sanitary sewer; and, 2) paving of the parking lot with storm drains and water quality device prior to discharge into the Duwamish River; 3) installing a new point of release and improving the existing outfall with rip rap and logs. General Information Project Name: George Long –City Shops Applicant: City of Tukwila Public Works/Mike Cusick Location: 14000 Interurban Avenue S.., Tukwila, WA and the right of way south of the shops and S. 140th St. from vacated Maule Avenue to the Duwamish River Zoning: Commercial/Light Industrial (C/LI )—west along Interurban Ave. S Low Density Residential (LDR) —East to the Duwamish River Comprehensive Commercial/Light Industrial (C/LI) —west along Interurban Ave. S Plan Designation Low Density Residential (LDR) —East to the Duwamish River Review Process The proposed action is subject to State Environmental Policy Act (SEPA) review as the project does not meet the exemptions listed under Part Nine—Categorical Exemptions (WAC 197 -11 -800) Background /Proposal The George Long Shops have been in existence for many years. Prior to purchase by the City of Tukwila in the 1970s, it was owned by a trucking company. A catch basin structure was previously plumbed into the City of Tukwila sanitary sewer. At some point the structure broke, allowing effluent to travel directly into the ground, rather than into the Rf 1 01/06/2009 H: \George Long Shops - -E08- 018\ E08 -18 -- GeoLongShop.SEPAstaffrept.doc sewer. The catch basin will be replaced and plumbed into the sanitary sewer once again by this project. In addition, a gravel parking lot will be paved with storm drains and water quality device. A new outfall with riprap and other shoreline stabilization will be placed in the Duwamish River. Recommendation Determination of Non - Significance (DNS) Existing Environmental Information Limited Phase Two Environmental Site Assessment (PBS, 8/07) Summary of Environment Impacts The following describes the impacts of primary elements contained within the Environmental Checklist submitted for the proposed project. Earth The areas where the work will be performed have slopes of less than 2 %, while the riverbank slopes are in excess of 100 %. Some grading and structural fill will be needed to provide a base for parking lot paving and for reconstructing S.140th St. The exact amount is not known at this time. No specific soils information is available, but alluvial soils, native sands and silts are typical of the Duwamish River shoreline. No known slide danger is present. Approximately 20, 000 s.f. of impervious surface will be added as parking areas are paved. During construction, silt fences will provide erosion control. Bank stabilization will be provided for the new outfalls. Air Some dust and internal combustion engine emissions associated with the use of construction equipment will occur during the grading and construction of the project. Common dust - suppression techniques shall be used during construction. Water In general, the project will improve water quality, with a new outfall and enhancements to the existing outfall. The Duwamish River is east of the City -owned property. Work within the 200' shoreline zone will include replacement of sanitary sewer lines to the City shops and existing single - family residence at the east end of S. 140th. The existing 18" outfall to the river will remain in place with additional riprap installed to dissipate energy. The proposal would increase the number of roadside catch basins. This may have the effect of diverting surface water runoff from the streets and paved parking area. Water would flow to the proposed outfall at the Duwamish River, and a water quality unit that would monitor runoff. The project will comply with all applicable City of Tukwila requirements for storm water runoff treatment. Rf 2 01/06/2009 H: \George Long Shops-- E08- 018\E08- 18-- GeoLongShop.SEPAstaffrept.doc Plants Deciduous trees (alder, maple, aspen), evergreens, and shrubs are at the site. Limited removal of vegetation will be needed to construct improvements. Native landscaping will be used to replant disturbed areas within 200 feet of the Duwamish River. Animals Salmon have been observed in the Duwamish River. Songbirds have been observed on the site. This area is part of the Pacific Flyway, a primary corridor for migratory bird species. Many common species of rodents, small mammals and amphibians may be on the site on occasion due to its proximity to the river, low - density development and the golf - course . Energy/Natural Resources The completed pressure washer at the wash pad will use electricity. Environmental Health/Noise There are no known environmental health risks on site. Construction noise levels will need to comply with City of Tukwila noise ordinances. Land/Shoreline Uses The zoning and comprehensive plan designations for the site are Low Density Residential (LDR) and Commercial/Light Industrial (C/LI). The City of Tukwila George Long Shops is a steel frame metal building. Adjacent uses are roadways, single family homes, the City- owned Foster Links golf course, City of Tukwila Police storage yard and several casinos. Land within 200 feet of the mean high water mark of the Duwamish River is in the Shoreline Overlay District, and is designated Urban Environment. Housing No housing will be provided or lost. Approximately 20 City employees work at the subject site. Aesthetics No views will be blocked. Improvements are at grade or below. Light and Glare No changes are planned to the existing parking lot lights. Recreation Foster Golf Links is adjacent to the north, and east across the Duwamish River. No recreational uses will be replaced. Rf 3 01/06/2009 H: \George Long Shops - -E08- 018 \E08 -18 -- GeoLongShop.SEPAstaffrept.doc Transportation Bus service is available along Interurban Avenue South. No additional traffic will be generated due to the proposed improvements. Public Services The shops need for very occasional need for police and fire service will remain unchanged. Utilities Electricity, water, garbage and recycling service, telephone and sanitary sewer are available to serve the project site. Public Comments None received Recommendation Staff recommends a Determination of Non - Significance (DNS).

Oil/Water Separator & Outfall Improvements File #: E08 -018 Summary of Proposed Action The Tukwila Public Works Department proposes to make improvements to the City shops facility, including: 1) installation of a wash pad connected to an oil /water sewer and sanitary sewer; and, 2) paving of the parking lot with storm drains and water quality device prior to discharge into the Duwamish River; 3) installing a new point of release and improving the existing outfall with rip rap and logs. General Information Project Name: George Long –City Shops Applicant: City of Tukwila Public Works/Mike Cusick Location: 14000 Interurban Avenue S.., Tukwila, WA and the right of way south of the shops and S. 140th St. from vacated Maule Avenue to the Duwamish River Zoning: Commercial/Light Industrial (C/LI) —west along Interurban Ave. S Low Density Residential (LDR) —East to the Duwamish River Comprehensive Commercial/Light Industrial (C/LI) —west along Interurban Ave. S Plan Designation Low Density Residential (LDR) —East to the Duwamish River Review Process The proposed action is subject to State Environmental Policy Act (SEPA) review as the project does not meet the exemptions listed under Part Nine — Categorical Exemptions (WAC 197 -11 -800) Background /Proposal The George Long Shops have been in existence for many years. Prior to purchase by the City of Tukwila in the 1970s, it was owned by a trucking company. A catch basin structure was previously plumbed into the City of Tukwila sanitary sewer. At some point the structure broke, allowing effluent to travel directly into the ground, rather than into the Rf 1 01/06/2009 H: \George Long Shops - -E08- 018\ E08- 18-- GeoLongShop.SEPAstaffrept.doc • • sewer. The catch basin will be replaced and plumbed into the sanitary sewer once again by this project. In addition, a gravel parking lot will be paved with storm drains and water quality device. A new outfall with riprap and other shoreline stabilization will be placed in the Duwamish River. Recommendation Determination of Non - Significance (DNS) Existing Environmental Information Limited Phase Two Environmental Site Assessment (PBS, 8/07) Summary of Environment Impacts The following describes the impacts of primary elements contained within the Environmental Checklist submitted for the proposed project. Earth The areas where the work will be performed have slopes of less than 2 %, while the riverbank slopes are in excess of 100 %. Some grading and structural fill will be needed to provide a base for parking lot paving and for reconstructing S.140th St. The exact amount is not known at this time. No specific soils information is available, but alluvial soils, native sands and silts are typical of the Duwamish River shoreline. No known slide danger is present. Approximately 20, 000 s.f of impervious surface will be added as parking areas are paved. During construction, silt fences will provide erosion control. Bank stabilization will be provided for the new outfalls. Air Some dust and internal combustion engine emissions associated with the use of construction equipment will occur during the grading and construction of the project. Common dust - suppression techniques shall be used during construction. Water In general, the project will improve water quality, with a new outfall and enhancements to the existing outfall. The Duwamish River is east of the City-owned property. Work within the 200' shoreline zone will include replacement of sanitary sewer lines to the City shops and existing single - family residence at the east end of S. 140th. The existing 18" outfall to the river will remain in place with additional riprap installed to dissipate energy. The proposal would increase the number of roadside catch basins. This may have the effect of diverting surface water runoff from the streets and paved parking area. Water would flow to the proposed outfall at the Duwamish River, and a water quality unit that would monitor runoff. The project will comply with all applicable City of Tukwila requirements for storm water runoff treatment. Rf 2 01/06/2009 H: \George Long Shops - -E08- 018\ E08- 18-- GeoLongShop.SEPAstaffrept.doc • • Plants Deciduous trees (alder, maple, aspen), evergreens, and shrubs are at the site. Limited removal of vegetation will be needed to construct improvements. Native landscaping will be used to replant disturbed areas within 200 feet of the Duwamish River. Animals Salmon have been observed in the Duwamish River. Songbirds have been observed on the site. This area is part of the Pacific Flyway, a primary corridor for migratory bird species. Many common species of rodents, small mammals and amphibians may be on the site on occasion due to its proximity to the river, low- density development and the golf - course . Energy/Natural Resources The completed pressure washer at the wash pad will use electricity. Environmental Health/Noise There are no known environmental health risks on site. Construction noise levels will need to comply with City of Tukwila noise ordinances. Land/Shoreline Uses The zoning and comprehensive plan designations for the site are Low Density Residential (LDR) and Commercial/Light Industrial (C/LI). The City of Tukwila George Long Shops is a steel frame metal building. Adjacent uses are roadways, single family homes, the City - owned Foster Links golf course, City of Tukwila Police storage yard and several casinos. Land within 200 feet of the mean high water mark of the Duwamish River is in the Shoreline Overlay District, and is designated Urban Environment. Housing No housing will be provided or lost. Approximately 20 City employees work at the subject site. Aesthetics No views will be blocked. Improvements are at grade or below. Light and Glare No changes are planned to the existing parking lot lights. Recreation Foster Golf Links is adjacent to the north, and east across the Duwamish River. No recreational uses will be replaced. Rf 3 01/06/2009 H: \George Long Shops - -E08- 018\ E08- 18-- GeoLongShop.SEPAstaffrept.doc • • Transportation Bus service is available along Interurban Avenue South. No additional traffic will be generated due to the proposed improvements. Public Services The shops need for very occasional need for police and fire service will remain unchanged. Utilities Electricity, water, garbage and recycling service, telephone and sanitary sewer are available to serve the project site.

The work was performed in accordance with the PBS proposal dated July 10, 2007. The intent of the investigation was to conduct a limited assessment of the current condition of subsurface soils and/or groundwater that might have been impacted by historic usage of the property. This report summarizes the history of the site, presents the results of the current investigation, and discusses PBS' conclusions and recommendations based on these results. 1.1 Site Description The subject property is located in Tukwila, a smaller city to the south of Seattle (see Figure 1). The area supports a mix of light industrial and commercial uses. The property encompasses a site on the east side of Interurban Boulevard at South 140th Street and is adjacent to the City of Tukwila Parks Department and a golf course. The Green River is immediately east of the subject property. The site is relatively level, with a slight regional downgradient slope toward the east. 1.2. GeologyfHydrogeology The subject property is located in the Puget Sound Basin. The Puget Sound Basin was partially filled with thick accumulations of sand, gravel and till by at least four separate periods . of glaciation within the past two million years. Periods of glaciation were followed by lacustrine, alluvial, and marine deposition of clay, silt, sand, gravel, and peat. The findings of the current investigation indicate that subsurface soils are ' generally homogeneous, consisting of sandy silt in the upper portions of the soil horizon, with sand below approximately 12 feet below ground surface (bgs). Boring logs are presented in Appendix B. Goundwater was encountered in six of the borings at depths ranging from 11.5 to 12.5 feet bgs. Based on topography, the local groundwater flow direction is expected to flow northeast toward the Green River. 2.0 BACKGROUND The George Long Shops have been in existence for many years with the subject property previously owned by a trucking firm. The basic infrastructure at the site was in use prior to the 1970s, when the property was purchased by the City of Tukwila. A catch basin structure was located in the floor of the southeast portion of the shop, which at one time was plumbed into the City of Tukwila sanitary sewer system. For an unknown period of time, the base of the catchbasin was compromised, with the piping system no longer allowing effluent to travel from the structure into the City system. Instead, with the system broken, the structure operated like a dry well, with liquids from the shop draining into the soil beneath, instead of the sewer. PBS Report Date: August 2007 Project #: 40407.009 • • Limited Phase Two Environmental Site Assessment 14000 Interurban Boulevard South Tukwila, Washington Recently, the City of Tukwila decided to upgrade the catchbasin system at George Long Shops, with a large catchbasin structure planned outside of the south door of the shop. Plumbing from the planned structure will drain into the City sanitary sewer system. Prior to completion of the new system, the City decided to perform an environmental site assessment to determine if the current floor drain system was impacting soil and groundwater beneath the subject property. This report provides information concerning the outcome of that assessment. 3.0 PURPOSE AND SCOPE The purpose of this investigation was to conduct a limited assessment of the current condition of subsurface soils and/or groundwater that might have been impacted by historic usage of the George Long Shop property. The scope of work completed by PBS consisted of the following: 1) Review the history of the subject property to discern the best location for borings and access to the . subject property. This also includes reviewing utility locate information concerning the shop and surrounding area. 2) Field locate drilling locations on the south, east and north portions of the building, including a drilling location within the existing floor drain structure. 3) Using a Strataprobe direct -push sampler, collect soil and/or water samples from ten (10) boreholes located around the property (Figure 2). 4) Complete a report, which includes a description of the methods, fieldwork, observations and analytical results, with sample documentation and interpretation of the results. 4.0 FIELD METHODS Fieldwork was conducted following PBS' standard Health and Safety Policies and Procedures. A utility locate was requested from the One -Call public locate system, and a private locator further verified markings in the vicinity of drilling locations. All marked underground utility locations were carefully inspected prior to start of work. On August 16 and 17, 2007, PBS directed a subsurface investigation on the subject property. ESN of Olympia, Washington, completed the drilling using a truck- mounted, direct -push Strataprobe unit. Ten borings were advanced in the locations shown on the attached Site Vicinity Plan (Figure 2). Borings were advanced to depths ranging from of 11 to 16 feet bgs. Continuous sampling was completed by driving a 2 -inch diameter stainless steel solid barrel sampler through the entire drilled horizon in each boring. Soil samples were collected in 4 -ounce jars from 4 -foot Macro- core solid barrel samplers lined with PVC sleeves. One soil sample was collected from each boring at varying depths of approximately 10.5 to 13.5 feet bgs (see Appendix B for specific sampling depths). One soil sample from each boring was submitted for laboratory analysis (see 2 PBS Report Date: August 2007 Project #: 40407.009 Limited Phase Two Environmental Site Assessment 14000 Interurban Boulevard South Tukwila, Washington Section 5.0 below). Groundwater was collected from one of the borings (B -5, in the floor of the sump) and submitted for laboratory analysis. Soils were logged in each boring using ASTM/Unified Soil Classification System techniques. A photoionization detector (PID) was used to measure environmental parameters indicative of petroleum hydrocarbon contamination in each boring interval. Soils were also field - screened for visual or olfactory evidence of petroleum contamination. All samples were stored in an iced cooler until released to the analytical testing laboratory within the holding time for the specified constituents. Upon completion of sampling, borings were backfilled with bentonite and the asphalt surfaces sealed with asphalt cold patch to match surrounding surfaces. Soil wastes from the borings were removed for disposal. Graphic logs of subsurface soil conditions are presented in Appendix B. Copies of all laboratory reports and sample chain -of- custody forms are presented in Appendix C. Results of testing are discussed below, and are also presented in Table 1. 5.0 SAMPLING AND ANALYSIS Borings B -1 to B -4, were completed on the south side of the building in the area where the new catchbasin system is to be completed; work was completed here to determine if contamination exists in the planned construction zone. Boring B -5 was completed within the floor drain sump inside the building. A boring was completed at the sump location to determine if contamination existed at the most probable point of contaminant release. Borings B -6 and B -7 were completed east of the building at a possible downgradient direction from the floor drain system to check for contamination in that direction. Borings B -8, B -9 and B -10 were completed on the north side of the building, north to northeast of the sump in order to determine if contaminant flow from the floor drain had migrated that direction. Samples were transported to Advanced Analytical Laboratory in Redmond, Washington, with chain -of- custody documentation. Analysis for Total Petroleum Hydrocarbons as diesel extended (NWTPH -Dx) and gasoline (NWTPH -Gx) was completed for all of the samples. Other analytical procedures completed on some of the samples included benzene, toluene, ethylbenzene and xylenes (BTEX); volatiles by EPA Method 8260; Method 8270 PAHs and glycols by EPA Method 8015. Several chemicals were detected in the water sample from Boring B -5 including propylene and ethylene glycol (EPA Method 8015), fluoranthene and pyrene (both PAHs Method 8270 constituents) and heavy oil by NWTPH-Dx extended. The Washington State Department of Ecology (WDOE) Model Toxics Control Act (MTCA) provides cleanup levels which are applicable to this site through the cleanup regulations in WAC Chapter 173 -340. Groundwater contamination in diesel -range petroleum hydrocarbons was PBS Report Date: August 2007 Project #: 40407.009 • • Limited Phase Two Environmental Site Assessment 14000 Interurban Boulevard South Tukwila, Washington present in Boring B -5, with none of the other above listed constituents exceeding Method A Unrestricted or Method B formula values from CLARC (Cleanup Levels and Risk Calculations under the Model Toxics Control Act Cleanup Regulations, Version 3.1). The groundwater from Boring B -5 contained 25 milligrams per liter (mg/L) heavy oil (equivalent to 25,000 micrograms per liter). The MTCA Method A cleanup level for heavy oil in groundwater is 500 micrograms per liter (ug /l) (equivalent to 0.5 mg/L). Results of the assessment indicate that none of the soil samples contain detectable contamination in any of the above listed parameters. The soil and groundwater sample laboratory analysis results are presented in Table 1. 6.0 CONCLUSIONS Analytical results indicate that a localized release of heavy oil into subsurface groundwater appears to have occurred at the sump within the George Long Shop on the subject property. The heavy oil concentrations found in the groundwater samples exceeds the MTCA Method A cleanup levels for groundwater. With no light petroleum constituents detected in Boring B -5 and no soil contamination detected downgradient, it is unlikely that heavy oil contamination spread very far from the point of release in the sump of the shop. The silty soil may be effectively stopping the migration of heavy oil, which will remain soil bound and probably not travel far with groundwater. The water table in Boring B -5 was approximately 7.7 feet bgs, with the water table elevation in the other borings at 12 feet bgs. This information suggests that a groundwater mound was present at the location of the sump, probably caused by releasing waste water recently at that location. 7.0 RECOMMENDATIONS Further water disposal to the sump location should be stopped. Before the sump is used again it should be plumbed into the City sanitary sewer system. To provide remediation, we recommend that the City vacuum out all the water and as much of the loose soil as possible from the base of the sump with a vacuum truck. If water returns in the base of the sump, vacuum the water out on at least three consecutive sessions. Remove as much of the waste oil contaminated soil as possible. The process will be to remove the contaminated water and soil from the base of the sump until cleanup is achieved. After the procedures have effectively removed the contaminated water, PBS can collect a water sample for analysis. Since water probably will not return in sump after vacuum removal, it may be necessary to deepen the sump to at least 14 feet below ground surface. The sump can be extended to depth by driving a capped, finely slotted pipe to the deeper depth (the pipe needs to be at least 2" I.D.). The sump will then be effectively deepened to the depth necessary to pump groundwater from the base of the structure. A 2" dedicated 12 volt submersible pump can be purchased and dropped to the base of the pipe /sump, with water periodically pumped out into a drum or holding PBS 4 Report Date: August 2007 Project #: 40407.009 Limited Phase Two Environmental Site Assessment 14000 Interurban Boulevard South Tukwila, Washington tank.

If the contaminated groundwater water is localized to the sump, as we suspect, the groundwater withdrawal will probably achieve cleanup with a limited independent remedial action completed. The collected groundwater will need to be analyzed for suspected contaminants prior to determining whether it can be disposed through the City sanitary sewer system; if not it may be sent to a contaminated water disposal facility. The City may want to use their tanks, vacuum truck and other equipment to complete the major portion of the project. PBS recommends that we be contracted to help oversee the remediation portion of this project. Following cleanup and groundwater conformational testing, a limited remedial action report will be provided that summarizes the project. This report, and any further cleanup reports, should be filed with property records as a record of environmental conditions on the subject property at, the time of this assessment and remedial action. 8.0 LIMITATIONS PBS has prepared this report for use by the City of Tukwila.

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. RECEIVED SEP 2 5 2008 COMMUNITY DEVELOPMENT 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 - Continue to Question 2 -0 YES1- 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 40 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 YES 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 MI 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. 4- Continue to Question 6 -0 YES - Continue to Question 6 -0 P: \Laurie - Admin \Mike \SEPA George Long EPASC 090408.doc City of Tukwila 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 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 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 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) Continue to Question 1 -4 City of Tukwila 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) 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) CD 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. 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? Please circle appropriate response. NO - Continue to Question 3 -0 (Page 1) CDContinue to Question 2 -5 2 -5 Will the project involve clearing within 40 feet of the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? Please circle appropriate response.

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. 3 -1 Will the project involve the direct alteration of the channel or bed of a watercourse, the Green/Duwamish rivers, or Black River? For the purpose of this analysis, channel means the area between the ordinary high water mark of both banks of a stream, and bed means the stream bottom substrates, typically within the normal wetted -width of a stream. This includes both temporary and permanent modifications. Please circle appropriate response. NO - Continue to Question 3 -2 CDP Continue to Question 3 -2 3 -2 Will the project involve any physical alteration to a watercourse or wetland connected to the Green/Duwamish River? For the purpose of this analysis, "connected to the river means" flowing into via a surface connection or culvert, or having other physical characteristics that allow for access by salmonids. This includes impacts to areas such as sloughs, side channels, remnant oxbows, ditches formed from channelized portions of natural watercourses or any area that may provide off channel rearing habitat for juvenile fish from the Duwamish River. This includes both temporary construction alterations and permanent modifications. Watercourses or wetlands draining to the Green/Duwamish River that have a hanging culvert, culvert with a flap gate, diversion, or any entirely man -made or artificial structure that precludes fish access should answer Yes to this- question — Please- cir-c-le- appropriate- response.---- - - - - -- el Continue to Question 3 -3 YES - Continue to Question 3 -3 3 -3 Will the project result in the construction of a new structure or hydraulic condition that could be a barrier to salmonid passage within the watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, a barrier means any artificial or human modified structure or hydraulic condition that inhibits the natural upstream or downstream movement of salmonids, including both juveniles and adults. Please circle appropriate response. el Continue to Question 3 -4 YES - Continue to Question 3 -4 3 -4 Will the project involve a temporary or permanent change in the cross - sectional area of a watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, the cross - sectional area is defined as a profile taken from the ordinary high water mark on the right bank to the ordinary high water mark on the left bank. Please circle appropriate response. NO - Continue to Question 3 -5 CDContinue to Question 3 -5 3 -5 Will the project require the removal of debris from within the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers? For the purpose of this analysis, debris includes, but is not limited to fallen trees, logs, shrubs, rocks, piles, rip -rap, submerged metal, and broken concrete or other building materials. Projects that would require debris removal from a watercourse or the Green/Duwamish or Black Rivers as part of a maintenance activity should answer Yes to this question. Please circle appropriate response. NO - Continue to Question 3 -6 IgED Continue to Question 3 -6 City of Tukwila ESA Screening Checklist 3 -6 Will the project result in impacts to watercourses or wetlands that have a surface connection to another watercourse or the Green/Duwamish or Black Rivers but do not contain habitat conditions that support salmonid use? Such areas may include, but not be limited to hillside seeps and wetlands isolated from the watercourse or river that have a surface water connection to the watercourse or river but are not assessable, nor would be assessable to salmonids under natural conditions. Wetlands with a "functions and values" rating for baseflow /groundwater support of 9 and above (or moderate) as described in Cooke (1996) should be included. Please circle appropriate response. Continue to Question 3 -7 YES - Continue to Question 3 -7 3 -7 Will the project include the construction of artificial waterways or wetlands connected to a watercourse containing salmonids? For the purpose of this analysis, the construction of artificial waterways or wetlands includes wetlands, channels, sloughs, or other habitat feature created to enhance wildlife use, particularly waterfowl use, or may be attractive to wildlife, particularly waterfowl. Please circle appropriate response. Continue to Question 3 -8 YES - Continue to Question 3 -8 3 -8 Will the project include bank stabilization? For the purpose of this analysis, bank stabilization includes, but is not limited to, rip -rap, rock, log, soil, or vegetated revetments, concrete structures, or similar structures.
