This <br />fall under some type of open space easement with <br />p a ions that the site is unbuildable until such time as it can be <br />capable of supporting a suitable septic system, at which time a <br />^cpiat would likely be necessary. <br />Summary and Conclusions: <br />1.In most cases, percolation tests were taken deeper than the <br />allowable trench bottoms or deeper than the standard 12-18“ deoth <br />for mound systems. <br />2.Perc tests in many cases were not performed to completion (last 3 <br />readings vary by no more than 10%). <br />3.In some cases, borings were done after the perc testing; this is <br />backwards. Borings should indicate what depth to do perc testing <br />4. Many of the proposed mound sites are too steep for mounds based on <br />the slow perc rates. <br />5.primary and alternate drainfield sites are <br />within a power line easement which presumably subjects the sites <br />to vehicular traffic. <br />recommend that the site evaluator perform <br />additional testing in order to provide adequate drainfield sites, and <br />incorrectl^ or “do^oHlet^code! °Pini°n were done <br />PRIMARY ALTERNATE <br />Lot 1, Block 1 <br />Lot 2, Block 1. <br />Existing <br />Existing <br />Mound - ok <br />12.5 acres <br />to test <br />- no need <br />Lot 3, Block 1 B - retest B, C retest <br />Lot 4, Block 1 A - consider testing <br />shallower for shallow <br />trenches <br />Located outside of <br />lot - retest <br />Lot 5, Block 1 A - consider retesting A, B, C retest <br />shallower for shallow <br />trenches <br />Lot 1, Block 2 A, B retest outside <br />NSP easement A, B retest outside <br />NSP easement <br />V. <br />f' 1r <br />1 <br />ij <br />-■r <br />S'-- <br />4^: <br />I <br />r''' <br />Lot 2, £ <br />Lot 1, E <br />Lot 2, B <br />Outlot G <br />A - Perc <br />B - Perc <br />C - Slop
