/'� <br /> TO: Jeanne A. Mabusth, Zoning A ministrator <br /> FROM: Michael P . Gaffron, Sept!�c ystems Inspector <br /> DATE : April 17 , 1984 <br /> SUBJECT: #804 - Painters Creek (Ski- onka) Bayside Road - Subdivision - <br /> Soil Testing Review <br /> The additional testing required on Lot 9 as been completed and a report <br /> has been submitted for City review. The ots which required additional <br /> work have been reevaluated and this infor ation is now on file . I met <br /> with the site evaluator in early March an I am comfortable with his <br /> interpretations of the soil borings, whic I had earlier questioned. I <br /> would like to make the following comme�ts <br /> Lot 1 (Sites 9A & 9B) <br /> - Slope at tested sites averages 16-180 <br /> - Topographic location acceptable <br /> - Site drainage looks good <br /> - HOUSE SITING CAPABILITY - I RECOMME�D E ALLOW LESS THAN A 100 ' HOUSE <br /> SETBACK TO BAYSIDE ROAD, IN ORDER TO M NIMIZE POSSIBLE HOUSE ENCROACHMENT <br /> ON DRAINFIELD AREAS <br /> - Reported perc rates averagelo MPI in to foot of soil, both sites <br /> - Depth to seasonal saturation zone 4-5 ' <br /> - Soil survey indicates Kilkenny Loam <br /> - BECAUSE OF THE STEEP SLOPES, I WOULp R COMMEND THE TRENCHES BE NO <br /> WIDER THAN 2 ' <br /> - Based on depths to seasonal saturation indicated, the primary site should <br /> have a maximum trench depth of 1 ' , and the alternate site trenches no <br /> deeper than 2 ' <br /> - As for the site evaluator ' s notes, a c rtain drain might have some benefit <br /> here , although its effect might be t�in mal due to the fine soil textures <br /> present <br /> Lot 2 ( Sites l0A & lOB) <br /> - Slope at tested sites averages 12g <br /> - Topographic location - OK, but this is a slightly concave slope which <br /> will tend to hold water, so additional site drainage work may be beneficial <br /> during construction <br /> - House siting capability - I recommenld hat specific house site "envelopes" <br /> be established to protect drainfielc� s ' tes <br />
