Site Photo: Attached as Figure 1 <br /> Site Plan: Attached as Figure 2 <br /> B. Environmental Elements (HELP1 <br /> 1. Earth (help' <br /> a. General description of the site: <br /> (circle one): Flat, rolling, hilly, steep slopes, mountainous, other: <br /> Generally flat with gentle slope to southeast. Maximum elevation change about 7 feet. <br /> b. What is the steepest slope on the site (approximate percent slope)? <br /> Estimated 5% over ahoi it 10 feet in one local area. <br /> c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, <br /> muck)? If you know the classification of agricultural soils, specify them and note any <br /> agricultural land of long-term commercial significance and whether the proposal results in <br /> removing any of these soils. <br /> Site has had soil borings drilled to evaluate environmental conditions. Granular till with minor <br /> amounts of debris (wood, glass, ceramic, metal) extend from surface to between 1 and 3 feet <br /> deep, underlain by slightly gravelly fine sandy silt to slightly silty medium to fine sand to the <br /> maximum depth explored of 20 feet. Groundwater generally occurs between 5 and 8 feet <br /> below ground depending on location and season. <br /> d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, <br /> describe. <br /> e. Describe the purpose, type, total area, and approximate quantities and total affected area of <br /> any filling, excavation, and grading proposed. Indicate source of fill. <br /> I-ill will be nearby commercial borrow source - IUD <br /> f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. <br /> g. About what percent of the site will be covered with impervious surfaces after project <br /> construction (for example, asphalt or buildings)? <br /> Approximately 75% (estimate)- no change from existing <br /> h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: <br /> No erosion is anticipated. All excavation will occur on level ground and be entirely contained <br /> within the paved work area. Any backfill material will be used as it is delivered to Site. <br /> SEPA Environmental checklist(WAC 197-11-960) July 2018 Page 4 of 16 <br />
