Municipality of Ancl3orage < Dept.

The north half of the property has an existing well/septic on it. The septic system was upgrade in 1996 and has two drainfields and an alternator valve. Test holes were excavated on the south half of the lot and the percolation rates varied fi:om 9 to 19 minutes per inch. No groundwater was encountered in either hole. Per MOA subdivision guidelines we have identified a septic reserve area of 14,000 square feet on the south lot. The topography is gently sloping, fi:om west to east, at approximately 5-10%. Attached is a site plan which shows the reserve area and the nearby wells. The lot has no surface waters, or low lying swampy areas. In short, there no separation distance concerns to wells or surface waters. ;finYc~rUel;Te~ny ques~ '~ ;, please contact me at 337-6179.
