Memorandum TO: Jack Pace FROM: Nora Gierloff 13,&) RE: SEPA - Allentown Sewer/Water/Pumpstation Improvements Project DATE: June 7, 1996 Project File No. E96-0014 Project Description: The City of Tukwila plans to provide new sanitary sewer facilities as well as replace existing water lines within portions of the Allentown neighborhood. The sanitary system • will consist of nearly 8,000 lineal feet of eight inch gravity mains together with associated side sewer stubs, manholes, and connections in City owned street right-of-ways. The water system includes construction of approximately 7,000 linear feet of ten inch and eight inch ductile iron water mains and related auxiliary items, to include fire hydrants, valves, services, ect. in City owned right-of-way. The project also includes the construction of a stormwater pump station in the intersection of 122nd and 42nd Avenue South. It will be used to pump stormwater into the Green River through an existing outfall during periods of heavy rainfall when the River is unusually high. Agencies With Jurisdiction: Approval of construction plans by METRO Comments to SEPA Checklist: None Summary of Primary Impacts: 1. Earth - Soil will be disturbed during the process of trenching, laying pipe and refilling. Erosion control and revegetation measures will be used to minimize the effects of this disturbance. Construction will be within street right-of-way and pavement will be repaired to previous condition. 2. Air - There will be exhaust emissions from construction equipment during the project. Dust control measures in compliance with the Puget Sound Air Pollution Control Authority will be used as needed. The project will have no air emissions when complete. 3. Water - The stormwater pump will be used to control backflow during periods of heavy rainfall but no increase in the amount of water released into the River is expected. Groundwater will likely need to be pumped out of the sewer and water pipe trenches but the contractor will be required to use desiltation measures before releasing it into the drainage ditches. 4. Plants - Disturbed grassy areas will be replanted. No street trees will be removed. 5. Animals - No endangered or candidate species are known to be on site. 6. Energy and Natural Resources - The project will require energy for construction equipment and for vehicles coming to the site. 7. Environmental Health - No environmental health hazards are anticipated. Construction equipment operation will need to comply with Tukwila's noise ordinance. 8. Land and Shoreline Use - The proposed use will not adversely affect the existing use of the site as street right-of-way. 9. Housing - The proposal will not result in a change to the housing supply. 10. Aesthetics - The project is not subject to BAR requirements. 11. Light and Glare - The proposal will not generate light or glare. 12. Recreation - The proposal will not affect recreational facilities. 13. Historical and Cultural Preservation - The site is not known to have any historical or cultural significance. 14. Transportation - Construction phasing and flaggers will be used to minimize traffic delays and inconvenience to neighborhood residents. 15. Public Services - The project is likely to increase demand on other public services only to the extent that the installation of sewers may encourage infill development in the neighborhood.. 16. Utilities - The project will replace aging water lines with new pipes sized to meet future demand. New sewer lines will be installed and the area will gradually discontinue use of septic systems. This will increase demand at the METRO wastewater treatment plant. Recommended Threshold Determination: Determination of non -significance.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions to Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on difference parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. 'i he agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. A.

There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The City of Tukwila plans to provide new sanitary sewer facilities, as well as, replace existing water lines within portions of the "Allentown" area of the City. The project includes construction of approximately 7,000 LF of ten - inch (10") and (8") ductile iron water mains and related auxiliary items, to include fire hydrants, valves, services, etc. in the City -owned right-of-way, commonly known as S. 116th St., S. 124th St., S. 122nd St. and 43rd, 44th, 45th, 46th, 47th and 48th Ave. S. The sanitary system will consist of nearly 8,000 lineal feet of eight -inch (8") gravity mains together with associated side sewer stubs, manholes and connections also located in the above noted street right-of-ways. Work will also include surface restoration (in kind). See attached Exhibit. The project is also to include the construction of a stormwater pump station. The station is to be located within the intersection of 122nd and 42nd Avenue South and shall be designed to convey stormwater runoff out of the Allentown Drainage System during heavy rainfall periods. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site (s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project is located in its entirety in the corporate limits of the City of Tukwila, King County, Washington within Section 10, Township 23N, Range 4E. More specifically, in the area of City commonly known as "Allentown". This area is located west of I-5 BNSF Burlington Northern Railroad right-of-way, east of 42nd Avenue South and the Duwamish River and north of 124th Street and the Duwamish River. Please see enclosed Exhibit. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, mountainous, other . Description noted in bold print. b. What is the steepest slope on the site (approximate percent slope)? Approximately 4% to 5% slope in steepest areas (enbankments). Generally 1% to 3%. 3 • • c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. Sand, clay, organic matter and glacial till. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. While previous construction in adjacent areas have indicated that clays and organic materials may be exposed during pipe installations, there is no surface evidence of "unstable soils" in the immediate vicinity. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Import material will likely be required in trench and roadway repair/reconstruction. No net increase in fill will be provided. Unsuitable trench spoils will be loaded and hauled to waste per the City approved construction contract documents. Minimal roadway grading will be required for roadway repair. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. g. An increase in wind and water erosion of stockpiled materials adjacent to pipe trenching areas can be expected during the construction phase. The potential conveyance of eroded materials shall be mitigated for until construction is complete and vegetation is established. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project will be primarily aligned within paved streets. Approximately 35% of the existing project site (City rights -of -ways) are presently covered by impervious surfaces. After construction, the project site will be covered by approximately the same percentage of impervious surfaces (i.e., pavement surfaces will be repaired in kind). h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: The contractor will be contractually required to incorporate provisions for erosion control such as the use of straw bales, siltation basins, silt fencing during construction, etc. per the City approved construction contract documents. 2. Air a. What types of emissions to the air would result from the proposal (i.e. dust, automobile, odors, industrial wood smoke) during construction and when the 4 project is completed? If any, generally describe and give approximate quantities, if known. Temporary Exhaust emissions from equipment, both diesel and gas operated, will take place during construction. Dust may be emitted during construction phase (pipe installation, backfill, and roadway repair/reconstruction). b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to air, if any: The City approved construction contract will include provisions for dust and emission control during construction. Street cleaning/sweeping and compliance with the Puget Sound Air Pollution Control Authority shall be required by Contract. 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The Duwamish River is located (borders) along both the southerly and westerly boundaries of the Allentown area of the city. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Some work will be completed, within existing City/roadway right-of- way limits, in areas which are adjacent to the Duwamish River. Please see attached exhibit. Work will not be over or in the "waters". 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities, if known. Trench dewatering with conventional trench sump pumps (trash pumps) are anticipated due to expected groundwater seepage into the trench section (pipe construction). 5 5) Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. No. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities, if known. Some dewatering is anticipated to occur due to the seepage of groundwater into the trench excavation area, during pipe line installation. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the.number of animals or humans the system(s) are expected to serve. None anticipated. The completion of this project should result in the reduction of environmental damage currently caused by the utilization of "failed" private septic drain fields in the area which will be abandoned, over time, as the result of connections to the permanent public sewer system being installed as a part of this proj ect. c. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if know). Where will this water flow? Will this water flow into other waters? If so, describe. N/A. 2) Could waste materials enter ground or surface waters? If so, generally describe. No. 6 d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Methods to minimize and mitigate construction related erosion will be provided in design and within the City approved construction contract documents. Methods include the use of silt fence, siltation ponds and straw bales to entrap migrating silt on site and the placing of filter fabric over catch basins to restrict silt from entering the existing storm system. Grassed areas disturbed by the construction of this project shall be re -seeded. Any significant dewatering will be routed to existing suitable roadside ditches, as may be pre -approved by the City, and/or the existing METRO sewer system, as may be pre -approved by METRO. 4.

SUPPLEMENTAL SHEET FOR ALL PROJECT AND NON PROJECT PROPOSALS The objectives and the alternative means of reaching the objectives for a proposal will be helpful in reviewing the aforegoing items of the Environmental Checklist. This information provides a general overall perspective of the proposed action in the context of the environmental information provided and the submitted plans, documents, supportive information, studies, etc. 1. What are the objective(s) of the proposal? The objectives of this proposal were provided in the Utilities Element of the City's Land Use Policy,_, Plan, namely: • The elimination of any point or non -point pollution sources associated with sewage disposal systems. In areas such as Allentown of continuous septic and drain field failures, the installation of sanitary sewer facilities should be accomplished, and • the replacement of old and deteriorated water lines to meet infrastructure standards that are appropriately scaled for use specified in the City's Land Use Policy Plan. 2. What are the altemative means of accomplishing these objectives? Septic and drain fields would need to be rebuilt or maintained in order to reduce the point or non - point pollution. No alternatives for the deficiencies in the water system. 3. Please compare the altemative means and indicate the preferred course of action: It is unfeasible to eliminate point or non -point pollution without building new sewers therefore construction of sanitary sewer facilities is the preferred course of action. 4. Does the proposal conflict with policies of the Tukwila Comprehensive Land Use Policy Plan? If so what policies of the Plan? No. Proposed measures to avoid or reduce the conflict(s) are: None.
