Nova.,.k Property 5 1 " Place Everett, Washington 99-11-10 5. Typical Wall Section A/6 calls out a maximum soil bearing pressure of 2000 psf. Note needs to be changed to reflect recommended allowable soil bearing pressure of 3000 psf for foundations placed upon undisturbed Glacial Till (Qvt) as called out for in the geotechnical report. Bearing soil should be confirmed by GES, Inc. at the time of excavation. 6. Deck Detail G16 shows deck footing at grade. Detail needs to be changed to reflect foundation placement recommendations in geotechnical report. Deck should be supported on minimum 12 inch diameter shafts with a minimum depth of 5 ft and a bottom of shaft a minimum 10 ft. from the top edge of slope at that same elevation where located adjacent to slop:•. The geotechnical report for this site prepared by GES, Inc. dated Nuts. 12, 1999 addresses site development and foundation placement and design considerations for a single family residence placed within 10 ft. from the top of slope at this specific site. The existing building design and foundation placement plan was available at the time that the geotechnical site investigation was completed and the report specifically addressed site development as proposed in the plans submitted to the City of Everett. The soils found below this lot are very dense and stable - there were no visual signs of recent or past instabilities noted along the adjacent slope at the time of our site reconnaissance. In addition, the conditions which are generally present that can lead to slope stability problems over time were not observed during our reconnaissance (ie: seepage's out of the slope, erosion problems along the slope, soil creep along the slope, etc.). This allowed us to look more favorably upon construction within the 25 ft. buffer zone required by the zoning codes. Cautions given in the geotechnical report need to be incorporated including following prudent and strict erosion control measures during and after construction and maintaining clearing and grubbing limits during site development. As always, GES, Inc. is available to provide construction inspection services upon request. By being involved during the initial stages of site development and foundation placement, we can address any problems that may arise and insure that the recommendations contained in the geotechnical report are followed by the contractor. 2 GES, Inc.
