A two test hole was excavated and found silty gravels GM,for the entire depth with no bedrock or water observed.The perc rate was 12 minutes per for each of the four test holes. From the site plan the slopes are fairly flat (less than 5-10 percent) at the test hole locations. The lots are large (one acre plus) and the soils are good with no ground water or bedrock. This permit will not impact any of the neighboring properties due to the lot layout. Please call me if you have any questions. Sincerely Michael N.
