WILLOW GLENN IV SEPA CHECKLIST1 | P a g e ENVIRONMENTAL CHECKLIST Purpose of checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. 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 for 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 different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The 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. Use of checklist for nonproject proposals: For nonproject proposals complete this checklist and the supplemental sheet for nonproject actions (Part D). The lead agency may exclude any question for the environmental elements (Part B) which they determine do not contribute meaningfully to the analysis of the proposal. For nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively. 2 | P a g e 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 proposed Willow Glenn IV project will redevelop an existing 12.53-acre homesite as a new 75-lot single-family residential plat. The site is located within the City of Yelm urban growth boundary at 9819 Grove Rd SE. Access to the project will be provided by two full-access driveways, one on Grove Road and one on Greenleaf Loop. 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 proposed project is located at 9819 Grove Rd SE in the City of Yelm UGA, parcel number 64303500100. The legal description of the subject parcel is as follows: “Lot 1 in Block 35 of McKenna Irrigated Tracts, as per plat recorded in Volume 9 of Plats, pages 43 & 44, records of Thurston County, Washington; together with that part of the south half of vacated Flume Land adjoining said lot on the north. Subject to covenants, conditions, and encumbrances of record, if any.” B. ENVIRONMENTAL ELEMENTS [Help] 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other...... The site is generally flat. The slope across the entire site is no greater than 2%. b. What is the steepest slope on the site (approximate percent slope)? The steepest slope on the site is 2%. 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. USDA’s Web Soil Survey (WSS) database1 indicates the main map unit present on the project site is Spanaway gravelly sandy loam, 0 to 3% slopes (110), comprising about 98% of the site. The remaining 2% of the site is comprised of Spanaway stony sandy loam, 0 to 3% slopes (112), found in the 1 https://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx 4 | P a g e southwest corner of the site. Both of these soil types are described as “somewhat excessively drained,” with a depth to water table of more than 80 inches. Additionally, there are several rock/dirt piles on the site from previous clearing activities, at heights of 5’ up to 18’ (see Sheets SV-01 and SV-02, Existing Conditions Survey, for additional detail). d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There are no surface indications or history of unstable soils in the immediate vicinity. 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. Approximately 8,600 CY of cut and 120 CY of fill are anticipated. On-site fill will be reused; select materials below hard surfaces such as asphalt paving and sidewalks will be imported to the site from a locally available source. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. During construction, erosion could occur as a result of denuded soil during or immediately following a storm event. To address this possibility, erosion and sediment control measures will be employed and maintained throughout the project as site conditions warrant. It is not anticipated that use of the site after construction will cause erosion. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? After project construction, approximately 26.5% of the site will be covered with impervious surfaces (roads and sidewalks). h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: An erosion control plan has been produced for the site as part of this preliminary subdivision submittal (see Sheet EC-01, Preliminary Erosion Control Plan, for additional detail). 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?

Emissions consistent with construction activities such as from trucks, heavy equipment, dust, etc. are expected during site construction. After construction, the principal source of minor emissions will be from automobile traffic and other uses typical of the surrounding area. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. There are no known off-site sources of emissions or odors that would affect this proposal. 5 | P a g e c. Proposed measures to reduce or control emissions or other impacts to air, if any: During construction, vehicles and equipment would be turned off when not in use. Appropriate dust control measures to prevent fugitive dust, including watering of exposed areas and dust covers for trucks, would be employed during construction. 3. Water [Help] 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. According to the Thurston County Geodata web mapping service, there are no surface water bodies on or in the immediate vicinity of the site. The closest surface water bodies are Yelm Creek, located approximately 1,800 feet southwest of the site, and the Nisqually River, located approximately 3,000 feet northeast of the site. 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, the project will not require any work over, in, or adjacent to any surface 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. No fill material would be placed in or removed from surface water or wetlands. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No, this proposal will not require surface water withdrawals or diversions. 5) Does the proposal lie within a 100-year flood plain? If so, note location on the site plan. According to FEMA’s Flood Map Service Center (MSC)2, flood map panel 53067C0354E, the project site is not located within a 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, this proposal would not involve any discharges of waste materials to surface waters. 2 https://msc.fema.gov/portal/home 6 | P a g e b. Ground 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 groundwater will be withdrawn, and no water will be discharged to groundwater. 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. There will not be any waste material discharged into the ground from septic tanks or other sources. c. Water runoff (including stormwater): 1) Describe the source of runoff (including stormwater) 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. Stormwater runoff will be generated by the site’s impervious surfaces, including the rooftops, streets, and driveways. Runoff produced within the proposed public right-of-way by the project will be collected and conveyed to two mechanical treatment devices (Oldcastle Perkfilter) then retained and infiltrated in a below-grade facility comprised of 48-inch perforated corrugated metal pipe surrounded by stone; see sheets SD-01 (Preliminary Stormwater Plan) and SD-02 and SD-03 (Preliminary Stormwater Details) for additional detail. Each parcel will manage its stormwater on that parcel, and a stormwater design for each parcel will be completed with each lot’s building permit application. 2) Could waste materials enter ground or surface waters? If so, generally describe. No, it is not anticipated that waste materials will enter ground or surface waters. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. Any stormwater produced by the project will be treated onsite. At a minimum, the site will meet the pre-project runoff rates and should not adversely affect drainage patterns in the vicinity. d. Proposed measures to reduce or control surface, ground, runoff water, and drainage pattern impacts, if any: Stormwater runoff from the site will be managed on-site. The proposed roadways are constructed with curbing and graded to contain the stormwater within the original parcel. Each house parcel will manage its stormwater on that parcel. Runoff flowrates will not exceed predeveloped conditions. 7 | P a g e 4. Plants [Help] a.
