B. Environmental Elements [HELP]. <br /> 1. Earth f helpf <br /> a. General description of the site: <br /> (circle one): Flat, rolling, hilly, steep slopes, mountainous, other <br /> Paved existing development,gradual sloping site. <br /> b. What is the steepest slope on the site (approximate percent slope)? <br /> Front inventory parking area—8% <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 /> Asphalt Pavement with Loose Medium dense sand with silt and variable gravel fill <br /> Galcial till below fill very dense sand with variable gravel. <br /> d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, <br /> describe. <br /> No surface indications or history of unstable soils <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 /> Grading of existing parking lot and excavation around the site to provide more usable <br /> parking area and landscape areas around the site. <br /> f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. <br /> Temporary Erosion Control Plans will be in place as part of the BMP's <br /> g. About what percent of the site will be covered with impervious surfaces after project <br /> construction (for example, asphalt or buildings)? <br /> 8% <br /> h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: <br /> Re-grading of main parking area, new retaiing wall proposed to improve topographical <br /> transition to adjacent site to the North. <br /> 2. Air fheipl <br /> a. What types of emissions to the air would result from the proposal during construction, <br /> operation, and maintenance when the project is completed? If any, generally describe and <br /> give approximate quantities if known. <br /> General construction emissions <br /> SEPA Environmental checklist(WAC 197-11-960) July 2016 Page 3 of 13 <br />
