Development Services Department On-Site Water & Wastewater Program 4700 Elmore Road Anchorage, AK 99507 Subject: Forest View Heights, Lot 16 – NHN Lewis Place Septic System Design Dear On-Site Services Engineer: The owner of the above lot intends to build a 3 -bedroom home on the property. We are submitting this permit application for the construction of a new well and septic system. The attached site plan identifies the location of the home and the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system on this lot or adj acent lots. A test hole was placed on the lot on August 11, 2020 in close proximity to the test hole placed by First Water Consulting on May 21, 2019. Soils encountered in our test hole varied significantly from First Water Consulting in than silty gravel was found to 16’ below the surface. The percolation rate of this material was determined to be 3.3 minutes per inch. No sand was found the full depth of the test hole. Our design is based on the subsurface soils found in our test hole. The ground surface on the lot slopes to the northwest at grades approximating 15%. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Ground contours are shown on the site plan indicating the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. Wells on this and adj acent lots are shown. The new system will be a minimum of 100’ from all wells and surface water and more than 5’ from the septic tank. Please refer to the attached test hole log and plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adj acent properties.
