TO: Mark E. Bernhardson FROM: Michael P. Gaffron, Assistant Zoning Administrator DATE: 10-8-85 SOBJRCT: Review of Stebbins' foundation boring report I have read the above referenced report, which indicates that the location Stebbins proposes to place hiz house has a potential for seasonally high water tables. This is not a unique situation with new construction in Orono. It is not apparent from the building plans submitted a exactly what elevation the basement f loor is proposed in relation to the pond area. However, it has been my experience that with the use of a few precautionary waterproofing measures, septic tanks and pump tanks can be made- relatively infiltration -free by a conscientious contractor. Stebbins also has .he option of placing the tanks at a higher elevation, using a sewage ejector pump for the bar-em-nt and gravity flow from the main f loor, and if need be install a the drain around the 1-piece precast tanks, which would virtually eliminate all seepage of groundwater into the tanks. Note that the foundation report did not review soils at the actual drainfield site east of the driveway. The report by Mark Gronberg dated 6-20-64 indi Cate ; percolation rates and indicated water table dept..s which are within the ac ble parameters for a mound -type drainfield system. Many suc`, systems are cL 'y being successfully used in Orono under similar soil and site cor. I s . I am convinced based on the information at hand that it is technically feasiL using common practices to provide a relatively trouble -free on -site sewage treatment system to serve this property.
