Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. None. 10. List any government approvals or permits that will be needed for your proposal, if known. Grading permit, Shoreline Substantial Development Permit, Construction Permit, and Floodplain Development Permit from the City of Auburn. Hydraulic Project Approval from the Washington State Department of Fish and Wildlife. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. 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. Three segments along the Dykstra Levee in the City of Auburn have been found to be below the height needed to provide flood containment of 12,000 cubic feet per second (CFS) plus an additional 3 feet of freeboard. The three sections of the Dykstra Levee that do not meet the requisite elevation are approximately 400, 600, and 960 feet long. Section A will be raised up to 3 feet. Sections B and C will be raised less than 1 foot. The work will involve stripping away the existing levee top surface of grass down to a stable substrate, which will be followed by adding suitable fill material to bring the levee height up to the appropriate elevation. The side slopes of the added fill will be contoured to match the existing slopes of the face and back of the levee. Some minor adjustments of the face of the existing levee may be needed to match the slope added material. In three locations, block retaining walls up to 30 feet long may be needed to support added fill on the landward side of the levee to avoid impacts to yards and existing homes. In conjunction with work on the Dykstra Levee, an approximately 35,590-square foot area along the waterward side of the levee that is currently dominated by invasive reed canary grass will be revegetated with native trees and shrubs to improve the currently degraded riparian habitat conditions. Form Updated: March 2019 Page 3 of 8 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 will occur on three segments of the Dykstra Levee in the City of Auburn, Washington. The work on Area “A” will occur on King County Parcel Numbers: 0721059038; 8944150000; 8944130000 The work on Area “B” will occur on King County Parcel Numbers: 7349400540; 7349400550; 7349400560; 7349400570; 7349400580; 7349400590; 7349400600 The Work on Area “C” will occur on King County Parcel Numbers: 7349400350; 734900360; 7349400370; 7349400380; 7349400390; 7349400400 Form Updated: March 2019 Page 4 of 8 B. Environmental Elements [help] 1. Earth [help] a. General description of the site: x flat,  rolling,  hilly,  steep slopes,  mountainous,  other b. What is the steepest slope on the site (approximate percent slope)? On the riverside, the levee slope inclination generally ranges from 44 % to 29 %. 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 agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. The Washington State Department of Natural Resources Geologic Information Portal indicated Quaternary Alluvium comprised of unconsolidated or semi-consolidated alluvial clay, silt, sand gravel, and/or cobble deposits comprise the expected soil profile in the project vicinity. Geotechnical drilling on the levee conducted by the King County Road Services Division Materials Laboratory encountered 3-6 inches of topsoil. Fill underlying the topsoil ranged from approximately 7-13 feet below ground surface and consists of loose to medium dense brown silty sand with grave to a poorly graded sand with silt and gravel. Alluvial deposits consisting of medium dense to dense gray gravel with silt and sand, to poorly graded sand with gravel, underlie the fill to the termination depth of the borings. The soils in the project area do not have agricultural or commercial significance. No soils will be extracted from the project sight. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Yes. A geotechnical report, prepared by the King County Road Services Division Materials Laboratory, evaluated subsurface and groundwater conditions in order to provide geotechnical recommendations of design and construction for the three identified low areas. The report indicated there have been no significant signs of erosion or material loss on the riverbank in the location of the proposed work. However, there have been several PL 84-99 repair projects along the Galli’s-Dykstra levee including in 1976, 1994, 2008, 2009 and in 2015. Some erosion at the levee toe from the 2020 flood events was identified during a site visit in June/July 2020. The current levee and proposed work are located in a mapped channel migration zone. However, the levee itself functions as an impediment to channel migration. The levee is currently armored with large rock, making it resistant to channel migration. The proposed work will not alter the channel’s natural planform pattern and migration process from the existing condition. The 2019 Green River System Wide Improvement Framework Report evaluated channel incision between 1986 and 2011 in this reach and noted two locations with incision greater than 3 feet at RM 28.99 and 30.59, both of which are located near the apexes of bends. 5 survey cross-sections were completed in this reach to evaluate changes in the channel since the 2006 survey for the flood insurance study and found very minimal or no change. Form Updated: March 2019 Page 5 of 8 e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. The purpose of the fill is to increase the elevation of three sections of the Dykstra Levee along the Green River so that it provides 3 feet of freeboard above flows of 12,000 CFS along the length of the levee. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Temporary erosion could occur as a result of land disturbance from grading, hauling of material and general project construction. There is potential for short term turbidity impacts on the Green River adjacent to and downstream of the project area during the construction, particularly if work is done in rainy weather. Erosion and sedimentation controls will be installed, as described below, to minimize the risk of impacts to water quality. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? No impervious surfaces will be created by this project. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: A Temporary Erosion and Sediment Control Plan will be developed prior to construction, and measures will be implemented both prior to and during ground disturbing activities, as needed. The following best management practices will be on-site or readily accessible during all construction activities: quarry spalls for temporary construction entrances, straw wattles, plastic sheeting, and silt fencing. Following construction, all disturbed areas will be vegetated to provide permanent stabilization. 2. Air [help] a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. The project has the potential to generate construction related dust. Dust control will be performed on an as-needed basis by stabilizing construction access surfaces and watering. Construction vehicles and equipment (excavators, dump trucks, pick-up trucks, etc.) will be used during construction. This equipment will emit gasses including carbon dioxide (CO2), methane and nitrous oxide, as well as others in much smaller amounts. 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: Engines will not idle unnecessarily and will be kept in proper working order with all filters and other emission control devices functional. To help reduce transportation costs, it is expected that the contractor will source construction materials from locations closer to the project site, thus helping reduce delivery vehicle mileage and corresponding emissions. Form Updated: March 2019 Page 6 of 8 3. Water [help] a. Surface Water. [help] 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 project is on a levee immediately adjacent to the Green River, which turns into to Duwamish Waterway before it drains into Puget Sound. The Green River is within Water Resource Inventory Area 9. 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. No work will occur in or over water. Construction will occur on a levee within 200 feet of the ordinary high-water mark of the Green River. Revegetation with native trees and shrubs will occur within a bench between the levee and the ordinary high water mark of the Green River. 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. No. 5. Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. All planned construction on the levee is at an elevation above the 100-year floodplain. Supporting documentation for this conclusion is provided in the Hydraulic and Hydrologic Analysis Report: Green River Dykstra Levee Improvement Project (King County, 2020). The proposed revegetation to improve riparian habitat is within the 100-year floodplain. 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 Water. [help] 1. Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No. 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. n/a c. Water runoff (including stormwater). 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. No new runoff will be generated by this project. Except for a slight proposed 1-2 % slope to the river from the improved levee areas, pre-and-post-project site conditions will be generally the same. Stormwater that doesn’t infiltrate into the levee surface will sheet flow toward the Green River. The project does not propose to construct any permanent on- site stormwater management systems (i.e., conveyance system, water quality facility, or flow control facility). A detailed analysis of runoff/stormwater management and the Form Updated: March 2019 Page 7 of 8 project’s compliance with the 2017 City of Auburn Supplemental Manual to the Stormwater Management Manual for Western Washington is provided in the Stormwater Site Plan Report: Green River Dykstra Levee Improvement Project(King County, 2020). 2. Could waste materials enter ground or surface waters? If so, generally describe. No. Waste materials will be prevented from entering the ground or surface waters by maintaining a clean site, properly disposing of debris and use of best management practices to contain material within the project site. 3. Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. Minor changes will be made to the roof runoff conveyance from the residential buildings landward of the levee and the crest of the levee will be slightly sloped (1-2 %) toward the Green River in the improved areas. Pre-and-post-project site runoff conditions will be generally the same. A detailed analysis of pre-and post-project site conditions is provided in the Stormwater Site Plan Report: Green River Dykstra Levee Improvement Project(King County, 2020). Form Updated: March 2019 Page 8 of 8 4. Plants [help] a. Check the types of vegetation found on the site: X deciduous tree:  alder,  maple,  aspen,  other  evergreen tree:  fir,  cedar,  pine,  other X shrubs X grass  pasture  crop or grain  orchards, vineyards or other permanent crops X wet soil plants:  cattail,  buttercup,  bullrush,  skunk cabbage,  other  water plants:  water lily,  eelgrass,  milfoil,  other  other types of vegetation b. What kind and amount of vegetation will be removed or altered? Grass and potentially some ornamental shrubs. d. List threatened and endangered species known to be on or near the site. The Green River is habitat for Puget Sound Chinook salmon and steelhead trout. Both are listed as threatened under the federal endangered species act. e. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: All existing native vegetation will be protected. The areas of work on the Dykstra Levee are currently predominantly grass-covered and will be seeded with native grasses after construction. In conjunction with the work on the levee, an approximately 35,590- square foot area along the waterward side of the levee that is currently dominated by invasive reed canary grass will be revegetated with native trees and shrubs to improve the currently degraded riparian habitat conditions. f. List all noxious weeds and invasive species known to be on or near the site. Blackberry and reed canary grass. 5. Animals [help] a. Check any birds and other animals which have been observed on or near the site or are known to be on or near the site. X Birds: X hawk, X heron, X eagle, X songbirds,  geese, X ducks, X crows,  other X Mammals:  deer,  bear,  elk,  beaver, X other (small mammals) X Fish:  bass, X salmon, X trout,  herring,  shellfish,  other b. List any threatened and endangered species known to be on or near the site. c. Is the site part of a migration route? If so, explain. The site is along the Green River, which is a migration route for chum, coho, pink, sockeye, and chinook salmon, steelhead trout. The river also contains resident cutthroat trout, mountain whitefish, rainbow trout, as well as a variety of non- salmonid fish species. d. Proposed measures to preserve or enhance wildlife, if any: The proposal will preserve wildlife habitat by keeping within the constructed footprint of the existing levee. No native trees or shrubs will be removed. All construction on the levee will occur on the levee crest above the 100-year floodplain. Erosion control measures will be used during construction and construction will occur in the dry season to minimize the risk of erosion, which could impact water quality and harm aquatic wildlife in the Green River. An approximately 35,590-square foot area along the waterward side of the levee that is currently dominated by invasive reed canary grass will be revegetated with native trees and shrubs to enhance the currently degraded riparian habitat conditions. This area is identified as critical for shade on the Muckleshoot Indian Tribe’s sun analysis maps due Form Updated: March 2019 Page 9 of 8 to its southern exposure. Over time the planted trees will provide shade to the river to contribute toward moderation of water temperature, as recommended in the Washington Department of Ecology’s Green River Temperature Total Maximum Daily Load (TMDL) Water Quality Improvement Report (2011). As the trees mature and eventually fall into the river, they will provide a source of large wood, which is critical for the formation of habitat features favored by salmonids that inhabit the Green River. e. List any invasive animal species known to be on or near the site. None 6. Energy and Natural Resources [help] a.

Fuel, oil, and hydraulic fluid may be on the project site during construction. 4. Describe special emergency services that might be required. None. 5. Proposed measures to reduce or control environmental health hazards, if any: All machinery will be inspected for leaks prior to entering the site. An emergency spill kit will be kept on the site at all times to respond to the potential loss of diesel gas, oil, or hydraulic fluid from construction machinery. All construction equipment will be refueled at a designated fueling area on the site that is as far as possible from the Green River. All equipment will be inspected daily to determine if there are leaking seals or gaskets that require replacement. Best Management Practices (BMPs) such as fuel containment and a spill response plan will be used during construction to reduce and control environmental health hazards. b. Noise. 1. What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? Minimal noise exists at the site vicinity. There is light vehicle traffic on adjacent and nearby residential streets. 2. What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. The project will generate some noise due to the use of heavy equipment, such as excavators, backhoes, and dump trucks. Construction of the project will likely take five to ten days and construction activities will be limited to hours between 7:00am and 7:00pm, Monday through Friday, or more stringent limitations required by the City of Auburn. 3. Proposed measures to reduce or control noise impacts, if any: Construction activities will be limited to weekday hours between 7:00am and 7:00pm, Monday through Friday, or more stringent limitations required by the City of Auburn.
