i <br />TO: Jeanne A. Mabusth, Zoning Administrator <br />FROM: Michael P. Gaffron, Septic System Inspector <br />DATE: June 14, 1982 <br />SUBJECT: #654 Dicon, 155 Willow Drive South - Additional On -Site <br />Testing <br />I have reviewed the submitted soil and site evaluation for the <br />two lots on the north side of t?a road in Phase 1. Testing <br />indicates average pert rates varying from 1 to 48 mpi, with <br />high water tables (saturateu zones) in all but the most northeasterly <br />site. Mound systems are apnlicai'e for all these sites, although <br />the northern site for Lot 1, could support a shallow <br />trench system. <br />I note that Lots 2, 3 _ d 4 in Block 2, have be -en realigned. <br />By superimposing the previous testing over the new lot lines, it <br />is apparent that 2 of the 6 perc tests originally done on Lot 4 <br />are now on Lot 3. Technically, additional testing should be done <br />within the boundaries of the revised Lot 4. --er, since the <br />soils appear to be fairly consistent througho :!,e division, and <br />since mounds will be used on all the lots, th- i:inor additional <br />testing is not critical and may be waived until a house is proposed <br />for the site. <br />I will reiterate that mounds should be placed on the most level <br />sites within the tested areas; and that prior to road construction, <br />all drainfiela sites shc..ld be staked off to eliminate traffic <br />or disturbance. <br />
