I havc madc an inspection of the absvc referenced site to assess the need for fotrndation drains'
The soil type is mapped as oxley. gravelly silt loarn, but a site investigation revealed that the
charactcristics more closely rcscmbre srrui, gr*etly silt loam (which is mapped near this site)'
The so, is wcu drained and the pcr-meability iJrnodei"tu to rapid; the percolation,rate is estimated
to be ovcr 4 inehes per hor,. Fo,ndEtion drains are not n..*rury on this site to assue the
protection of the proposed stnrohrres'
Another consideration is the grotrnd water table elevation. oxley soil formations normally have
pcrched wat6r tables that are near ur. r;;i;;;.. salem soil formations have water tables that are
greater than six feet deep. In eithsf case, high grourd water should not be a problem because the
drainage channel to the'north would allow a purohed Water table to "dtrairl"'
