Since that time no work has been done on the house, driveway or any other features on the lot. The well has not been constructed and the outhouse on the property has not been abandoned. We are submitting the inspection report to document the work that has been done to date and to satisfy our commitment to this project. We are unsure if the property has been abandoned or sold. We have had no contact with the owner since October of 2015. If further work is accomplished on the property or if contacted by the owner we will submit further documentation of both the proposed well and the septic system. At this time however our involvement in the work is complete. The ditch fronting the property is currently dry even after the constant rains of the past months. Drainage in the area may have been improved over the past two years making the requirement for a waiver to surface water unnecessary. Sincerely, 20�'J E_ a'c'x� Michael E. Anderson, P.E.

Lot 27A. This ditch was known to be dry up until the second week of September. The lowest absorption trench designed for the lot is 36' from the ditch at the closest point. A waiver is therefore necessary from the 100' setback required by Municipal Ordinance. We are proposing to construct a berm to the north of the absorption trench to insure any overflow of septic effluent will travel a minimum of 100' prior to discharge into the ditch which apparently flows only during the heavy, runoff pedods of the year. It is unlikely the septic system will overflow, but tha berm will insure no contamination can occur to water flowing in the ditch. We therefore request a waiver be issued al!owing the septic system to remain in its proposed location at 36' from the ditch. Sincerely, Michael E. Anderson, P.E. August 5, 2015 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Su~e~: Lots 26A and 27A, Block 7H, Rabbit Creek View & Heights Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: Lots 26A and 27A, Block 7H, Rabbit Creek View and Heights Subdivision have the same owner. He is intending to upgrade the structure on Lot 26A to a two~ bedroom home and intends to construct a septic system on Lot 27A. The well will be placed on Lot 26A We are therefore requesting a permit be issued for the construction of a new well and septic system. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. The existing outhouse and septic system components on the lot will be decommissioned in accordance with Municipal Code. No conflicts exist between the proposed septic system and well or septic systems on adjacent lots. The majority of the lots surrounding these lots are vacant. Drainage arrows and surface contours are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. The test holes placed on the lot in the area of the absorption trench and alternate site indicated gravel with varying amounts of silt (GM/ML). The absorption rate of the soil was determined to be 30 minutes per inch. No groundwater was found during the placement of the test holes and none was found during the monitoring period. An application rate of .6 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,000-gallon septic tank and a 36' long x 3' wide x 7' effective deptth absorption trench. The elevation of the distribution line in the absorption trench will be 3' below the surface and the total depth will be 10'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. Lot s 26A & 27A, Block 7H, Rabbit Creek View & Heights August 5, 2015 Page Two The ground surface on the lot in the area of the septic system slopes to the northeast at a grade approaching 20%. The new trench will be constructed parallel with the contours of the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from all wells and any surface water and 10' the proposed and existing water services in the area. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.
