TO: <br />FROM: <br />DATE: <br />Jeanne A. Manbusth, Building & Zoning Administrator <br />Michael P. Gaffron, Asst. Planning 6 Zoning Administrator <br />March 13, 1990 <br />Subject: #1503 Woodhill Country Club - <br />Subdivision - Septic Testing <br />1 have reviewed the site of the proposed building lot and <br />would make the following comments: <br />1. The testing for septic system // <br />bv s-P Testing indicates the use of a trench drainfieid <br />tystel on 2 terrace levels at the north east <br />steeply sloped lot. The tested sites provide the capability <br />for as much as 950 lineal feet of drainfieid, enough to <br />provide for a primary system and nearly 2 alternate systems <br />for a 5 bedroom home. <br />2 Since these sites are at the high end of the lot, one <br />would expect some under ground drainage <br />contours down the hill. With 80% of the lot <br />greater than 18%, it would be critical to <br />house directly downhill from the drainfieid sites. <br />Furthermore; it would be advisable to do no grade cuts <br />within 50' downhill from any of the <br />within 20’ laterally at a level equal to the sites. Because <br />these slopes near the drainfieid are so ®^®®P' ^ i <br />seem to be within the authority of the septic code to <br />require these special conditions on site grading. <br />^ To that end, I have sketched on the S P Testing design, <br />a* "proterted area" in which no structure and no grading or <br />cuts should occur. Based on the preservation of ®^®® <br />and the stipulation that no cuts occur, I would recommend <br />fUnr-oval Of^the building site, finding that the provisions <br />of'^the septic code for a buildable site are adequately met.
