Mf Lrr :-<v )j <br />October 30, 1980 <br />#582 H.R. Johnston <br />925 Willow Drive South <br />Page 2 <br />Lot 3, Block 1 (Cont.) <br />When this lot is developed, care must be taken to make sure the house <br />location does not encroach on the area to be preserved for drainfield. <br />I suggest that for this lot (and for all subdivisions in the City) that <br />the tested drainfield sites be somehow entered on the title or deed for <br />the property so that prospective buyers are made aware of the restrictions <br />on the lot. <br />Lot 4, Block 1 <br />This lot contains the existing H.R. Johnston home. Although the lot <br />as proposed contains only 1.64 acres, adequate area has been previously <br />tested and exists for use as future drainfield. A relocation of the lot <br />line between Lots 3 and 4 to give each property approximately 1.8 acres <br />would serve no purpose as far as drainfield sites are concerned. <br />Lot 1, Block 2 <br />The soils on this lot are considerably different than those of the <br />westerly lots. Loam and clay loam soils are indicated, and the percolation <br />rates were understandably slower. This lot contains 2.4 acres and has a <br />somewhat limited number of possible house locations which would allow a <br />gravity-flow drainfield system. The lot is acceptable for a standard <br />trench drainfield. Care must be taken during development of the lot <br />that drainfield trenches are kept away from the pothole in the center <br />of the lot. <br />Lot 1, Block 3 <br />m <br />This lot has loamy soils with a fairly good percolation rate. The tested <br />drainfield sites are to the immediate southwest of the existing paved <br />driveway and due to slope conditions appear to be the only likely sites <br />for use as drainfield. Again, care must be taken to preclude disruption <br />of these sites prior to development. It appears that the suggested location <br />of the house would be on the north end of the lot approximately on the <br />existing driveway. <br />Summary <br />Each of the five proposed new lots should be acceptable for standard trench <br />drainfield systems. Fortunately, this is one of the few areas of Orono <br />having sandier soils. Certain lots as indicated may have limiting sites <br />due to water table and slope constraints. As the engineer's report states, <br />it is imperative that the tested sites not be disturbed by further <br />excavation, grading or filling until permits are issued for specific <br />house locations. I recommend approval of the subdivision as per preliminary <br />plan with the above recommendations. <br />to
