KA No. 092-12004 <br /> August 24,2012 <br /> Page No. 2 <br /> • Recommendations for foundation design including allowable bearing pressure, anticipated <br /> settlements (both total and differential), coefficient of horizontal friction for footing design, <br /> and frost penetration depth; <br /> • Recommendations for seismic design considerations including site coefficient and ground <br /> acceleration; <br /> • Parameters for the design of slab-on-grade floors including recommendations for placement <br /> of capillary break material and vapor barrier below the slabs,if required; <br /> • Recommendations for the use, placement, and compaction of on-site soils and imported fill <br /> materials in the building and pavement areas; <br /> • Construction and excavation considerations, topsoil/unsuitable soil stripping depth, <br /> identification of potentially problematic soils or groundwater conditions, depth of over- <br /> excavation if required; <br /> • Design criteria for temporary excavations; <br /> • Discussion of relevant pavement design parameters and recommended pavement design; <br /> • Recommendations for pavement subgrade preparation; <br /> • Recommendations for site drainage and erosion control. <br /> PROPOSED CONSTRUCTION <br /> Current plans include a new café, drive-through lane and parking areas. The existing structures and <br /> pavement will be removed. It is our understanding that the proposed structure will likely include <br /> generally light to moderate foundation loads and a slab-on-grade. <br /> SITE CONDITIONS <br /> The site is located at the southeast corner of SE Everett Mall Way and 3rd Avenue SE in Everett, <br /> Washington. The property is generally level, and the site is currently occupied by commercial <br /> structures,paved areas,and a small amount of landscaping. <br /> GEOLOGIC SETTING <br /> The Preliminary Surficial Geologic Map of the Mukilteo and Everett Quadrangles, Snohomish County, <br /> Washington, prepared by Mackay Smith (State of Washington Department of Natural Resources — <br /> Division of Geology and Earth Resources, in cooperation with the U.S.G.S., 1976) indicates that the <br /> property is underlain by Quaternary Vashon glacial till (Qvt). Glacial till generally consists of a <br /> compact,unsorted mixture of silt, sand, gravel,cobbles and some boulders. <br /> Krazan&Associates,Inc. <br /> Eleven Offices Serving The Western United States <br />
