The geotechtrlcal report.for the Amblcside Meadows - 1 st Addition Subdivision recommends immediate moisture stabilization of exposed expansive sub-grades, and that expansive soils be qver-excavated and replaced with at least 12 inches of fill compacted to at least 95% of ASTM D698 for foundation preparation. The report also recommends that measures be taken to prevent water ~.~&U collecting in or around the foUndation areas during and ~fter the construction process, and that positive site drainage be provided to reduce the infiltration of surface water into the .expansive soils. The geotechnical. report further emphasizes that the finish grade of landscape soil adjacent to the foundation should be at least 24" above the expansive bearing soils, fi~ comDacted to reduce the infiltration of water at the surface. The adequacy of fill soil material around the building must be verified to the satisfaction of the design professional. 4 May-28-2003 09:05am From-K & A Eniineerini, Inc. +541-684-9358 T-201 P.006/006 F-044' Community Services Div, Building Safety L11 i OF SPRINGFIELD, OREGON 2255'" Strec(, Springfield, OR 97477 Ph. 726.3759 Job Address ~299 37th St. City Job #.coM 2003-00228 Affidavit For Site Investigation Questionnaire Foundation Sub-Grade Approval for Residential Building Site in Ambleside Meadows - 1 st Addition Subdivision The undersigned hereby affirms that the excavation, structural fill and moisture stabilization methods for the building site at the address shown above was observed by me or an authorized employee of my fmn and that the following is tme: 1.
