Seattle,Washington www.pacland.com T 206.522.9510 TURNING VISIONS INTO REALITY parking area and trees and bushes along the north and east property lines. There are also several raised planters at the front of the store and a 2,350 square foot landscaped area abutting the east side of the existing building. Additional perimeter landscaping is located along the Everett Mall Way Right-of-Way (ROW). See Figure 2 in Appendix A for the existing basin map. Drainage Stormwater from the project area is presently collected onsite by curbs, gutters, catch basins and a network of underground conveyance pipe. Runoff is directed to one of four underground detention pipes. From the detention pipes stormwater conveys to a flow control structure, located near the southern site entrance onto Everett Mall Way, which discharges to the City stormwater system in Everett Mall Way. Per information provided by the City of Everett, the system travels south down West Mall Boulevard and enters the Everett Mall stormwater facilities at the south end of West Mall Boulevard. The Everett Mall stormwater facilities discharge into Silver Lake Creek at approximately 1300 100`h Place S.E. which flows into Silver Lake. Soils Per the Geotechnical Report, prepared by Terracon Consultants and dated June 8, 2011, the site consists of very loose to medium dense silty gravelly sand and silty sand with gravel interpreted as fill material. The fill material was underlain by medium dense to very dense silty gravelly sand, which was interpreted as glacial till. The site is mapped as Alderwood-Urban land complex Urban Land (Ur) according to the USDA Natural Resource Conservation Service, Soil Survey for Snohomish County Area, Washington. The soil is assigned a Hydrologic Soil Group C rating. Ground Cover The existing project area is fully developed with a retail building, parking lot, drive-aisles, parking lot landscape and perimeter landscape. Critical Areas Based on a Critical Areas Reconnaissance Letter prepared by the Watershed Company and dated February 14, 2011, there are no critical areas on or adjacent to the site. Additionally, for the purposes of addressing Minimum Requirement #8 there are no known or observed wetlands onsite, and the downstream facilities and water bodies (City of Everett storm system, Everett Mall stormwater facility, Silver Lake Creek, and Silver Lake) are not classified as wetlands to the best of our knowledge. Therefore, no additional requirements apply to the project related to Minimum Requirement #8. Adjacent Areas Everett Mall Plaza Parcel Ill Retail Expansion Stormwater Site Plan — Page 8
