SEPA ENVIRONMENTAL CHECKLIST FOR Project Name AGENCY CEMEX-Mountain View Business Centre Div 9 USE 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 available. The proposed project is located at 6300 Glenwood Ave,WA 98203 within Sections 1, Township 28, Range 4 East with a corresponding parcel number 28040100303700. It is bounded by Glenwood Avenue to the east, Sievers and Duecy Boulvard to the south, Hardeson Road to the west, and Shuksan Way to the north. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site(underline one): Flat, rolling, hilly, steep slopes, mountainous, minimum sloped site. b. What is the steepest slope on the site (approximate percent slope)? Currently, this portion of the CEMEX site is a sand and gravel pit undergoing a simultaneous process of gravel extraction and reclamation. Excavation slopes of 80 percent and spoil pile slopes around 50 percent. The reclaimed site will generally slope down from southwest to northeast at 5 percent. The north and east sides will consist of a 2H:1V reclaimed slope. 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. Native on-site soils within the Glenwood CEMEX property are comprised primarily of sand and gravel overlain by a till cap. Reclaimed soils consist of a variety of approved non-organic material. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. None known. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. No earthwork activity is required for the BSP. The site continues to operate as a sand and gravel pit, portions of which are currently undergoing phased reclamation. It is anticipated that the reclamation process will leave the proposed lots in a condition suitable to support future development activities, although it is likely that future development may require some ground improvement (e.g. preloading). f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Page_lef42' LLW/6)
