The foundation sub-grade is capable of supporting a minimum of 1500 psf, and is adequate to support the building proposed for this site. 2. The moisture content of the excavation was adequately maintained during the site preparation process and was adequately covered to stabilized moisture content prior to any significant change in moisture content of the sub-grade. . 3. The site is adequately graded and drained to prevent the collection of water in the excavated area during constructicm. 4.

The report also recoxnmends that measures be taken to prevent water from collecting in or around the foundation areas during and afler the construction process, and that positive site drainage bC 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. frrmlv comoacted to reduce the inftltration 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 . .. 66/67/2662 66:49 5416849358 Communi.y Services Div, Bing Safe.y CITY OF SPRINGFIELD.
