Novaek Property 99-11-10 51" Place Everett, Wa. 4.6 Foundation Placement and Design Recommendations It is our opinion that shallow, isolated or continuous spread footings founded within the undisturbed native unweathered till soils will provide, a suitable foundation support for the proposed single family residence. All building foundations shall be placed so that the base of the foundation is a minimum of 10 feet from the slope. This is needed to provide for long term stability of the residential structure and to insure that the slopes are not impacted during construction or impacted on a long term basis by the presence of the residential structure. Preliminary site drawings provided by the Architect indicated that northwest portion of the house and the deck will be within 10 feet of the surface of the slope. The depth of the foundation shall be placed so that the base of the foundation is a minimum of 10 feet from the edge of the slope at that elevation. The deck can be supported by a minimum 12 inch diameter shafts with a minimum length of 5 feet or again the bottom of the shaft a minimum of 10 feet from the slope. An allowable soil bearing pressure of 3000 pounds per square foot (psf) may utilized for design of shallow footings founded in the gay, fine- to coarse -grained silty sand located between 1.5 to 3.0 feet below the ground surface at the location of our test pits. All footings should penetrate to a minimum depth of 0.5 feet into this strata to insure adequate bearing. No footings should be founded in or above any topsoil, undocumented fill, or loose native soils. 16 r GES, Inc.
