Box 196650 Anchorage, AK 99519-6650 Attention: . On Site Services Engineer Subject: Lot 15, Block 2, Sea Turn Subdivision Separation Distance Waiver Septic System to Excessive Slope Dear On Site Services Engineer:. Surface area available on the subject lot for placement of a septic system is severely limited by the presence of a stream at the southern border of the lot and the location of the wells and septic systems on the adjacent lots. The only available area is approximately 20' from the edge of a slope which exceeds a grade of 25% and drops to the creek. A waiver is therefore necessary to allow the new septic system to be constructed within 50' of this break in grade. The slope varies in grade from 26% to 35% and will be flattened dudng construction to allow a minimum of 50' from the edge of the pdmary and alternate sites to a break greater than 25%. A cross section of the finished slope will be furnished with the codified as built for the septic system verifying the separation distance. Sincerely, Michael E. Anderson, P.E. ANDERSON ENGINEERING P.O. BOX 240773' ANCHORAGE,,AK 99524 5'22-7773 677-7766,(FAX) August 20, 2007 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Su~ect: Lot 15, Block 2, Sea Turn Subdivision Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer:. The owner of Lot 2, Block 3, Sea Turn Subdivision intends to construct a new four- bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. No existing wells or septic systems are closer than 1,00' from the proposed well or septic system. Drainage arrows are shown on the site plan showing the grade and direction of flow on the lot. The property drops at a slope of between 25% and 40% at its midpoint toward Rabbit Creek. Some slope flattening will be required to insure the minimum separation distance from a slope greater than 25% is attained. The drainage pattern will not be changed as a result of this project. The test holes placed on the tract in the area of the absorption trench and alternate site indicated silty gravel with sand (GM) material. The percolation rate of the soil was determined to be between 1 and 5 minutes per inch. No groundwater was found during the placement of the test holes and none was noted 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 1,250-gallon septic tank and 2- 42' long by 3' wide by 6' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trenches will be 4' below the surface and the total depth will be 10'. A minimum of 3' of till or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. The alternate site will be an Advantex Treatment System with an absorption trench designed for an absorption rate of 3 gallons per day per square feet or 5' wide x 20' long with an effective depth of 4'. Lot 15, Block 2, Sea Turn Subdivision August 20, 2007 Page Two The ground surface on the lot in the area of the absorption trench is nearly fiat with a slight bias to the southwest. The new trench will be constructed parallel with 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 cons{ructed 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.

August 2.1, 2007 a~ It is my intent as the homeowner to construct a septic system on the property 6120 Azalea Dr Lot 15, block 2, Sea Turn sub. I have 20 years experience operating different types of equipment (backhoes, excavators, loaders, dozers, boom trucks, eot.). I excavated the foundation, the sewer and water lines for the house I built and currently live in. I have worked as a lineman for Norcon and Alaska Communications Systems building and maintaining underground plant during the past 15 years. I have built one new and rebuilt one other septic system, both of which are still working fine. I will be building the system and will be on the property the entire time it is being placed. I am planning to borrow an excavator from Jason Hodges for the project. If for some reason that becomes unavailable due to scheduling conflicts, I will rent one from Airport or United rentals. The project has been designed by; will be inspected and as-built by Anderson engineering.

We are therefore requesting a permit be issued for the construction of a new well and septic system to serve the home. The Site Plan and backup documentation identify the location and configuration of the proposed well, septic system and alternate site. No conflicts between the new septic system and other systems in the area have been noted. An existing well is located on the lot to the west which will impact placement of the septic system. Care must be taken to insure the 100' separation distance is met. Existing drainage arrows and the current drainage pattern are also identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. Test holes placed near the location of the absorption trench and alternate site indicated silty sand and gravel. The accepting soils were tested and found to have percolation rates of 30 to 60 minutes per inch. No groundwater was found during excavation and none was noted during the monitoring period. Our design includes the placement of a new 1,500-cjallon septic tank along with 2 - 54' long by 3' wide by 8' effective depth absorption trenches to collect and treat the sewage generated in the house. The bottom of the trench will be 11' below the surface. The distribution pipe will be 3' below the surface. The alternate site will be an Advantex treatment system to qualify for a reduction in trench length due to the limited surface area available. A minimum of 3' of cover will be placed atop the trenches and a minimum of 4' of cover will be placed atop the new septic tank. The ground surface on the lot slopes at grades from 2% to 5% from northeast to Lot 15, Block 2, Sea Turn Subdivision June 24, 2004 Page Two southwest in the area of the absorption trenches. The lot slopes more radically toward Rabbit Creek at the back of the house. The absorption trenches will be constructed parallel with the slope of the ground surface as much as possible in conformance with Municipal requirements. The new septic system will be constructed 100' from all wells and surface water, It will also be constructed a minimum of 10' from any water service 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.
