We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. A well was recently drilled on the lot to provide information for development of the subdivision. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. Also identified on the plans are the existing wells in the area and septic systems on surrounding lots. No conflicts exist between the proposed septic system and well or the proposed septic systems and wells on adjacent lots. Drainage arrows and ground 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 trenches and alternate site indicate silty gravel (GM). The percolation rate of the soil was determined to be 6 to 15 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 .8 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 57' long by 5' wide by 4' effective depth absorption trench to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 4.0' below the surface and the total depth will be 8.0'. 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. The ground surface on the lot in the area of the septic system is flat with only a very shallow grade to the northwest. The new trench will be constructed 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 Lot 7, Inlet View January 3, 2017 Page Two 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. 2. 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. 3. 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. 4. 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, W4,,j,L Z 04, , Michael E.

Work also includes the construction of a new 57' long X 5' wide X 4' effective depth absorption trench at the location also shown on the Site Plan. The distribution line in the trench will be placed at 4.0' below the existing ground surface. Total depth of the trench will be 8.0' below the existing ground surface. The new absorption trench and septic tank must be placed a minimum of 100' from all private wells and any surface water in the area and 10' from the water service line proposed for the lot. A minimum of 3' of cover is required over the absorption trench and 4' of cover over the septic tank. 2. Construction shall be in accordance with the approved site plan, design drawings, Municipal Permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. 3. The Contractor shall be responsible for obtaining all underground utility locates and for the layout of the septic system and verification of the location of all lot lines. The Contractor must also verify the location of wells in the area and assure that the separation distances are met. 4. Unless specifically agreed otherwise, the contractor shall be responsible for final grading areas subsequently depressed from soil settling. Property owner shall be responsible for revegetation of affected areas unless specifically agreed otherwise. 5. Contractors installing wastewater disposal systems must be certified by the Municipal Building Safety Division On -Site Water and Wastewater Program for system installations. Owners installing their own systems must receive prior approval from the On -Site Water and Wastewater Program. before beginning system installation. SEPTIC TANK INSTALLATION A new 1,000 -gallon septic tank must be procured from an approved source and installed at the location shown.

These inspections must be conducted under the supervision of a professional engineer registered in the State of Alaska. The first inspection must be conducted after the excavation of trenches, beds or pits and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled. The second inspection must be conducted after the placement of the geotextile fabric, gravel, distribution piping, standpipes, cleanouts and insulation. No backfill should be in place at the time of inspection. Contractor shall provide a copy of all field survey layout and construction notes for use in preparing the certified as -built of the completed system.

Test wells must be placed prior to the approval of the subdivision to verify sufficient water is available to serve the new subdivision. The owner of the parcel intends to construct a new well on proposed Lot 7 as part of the aquifer study. The well will remain in service after the subdivision is approved to serve a new single family home proposed for the lot. We are therefore requesting a permit be issued for the construction of a new well to accommodate the home and provide information for the aquifer study. The attached Site Plan and backup documentation identify the location and configuration of the well and the septic system reserve area on the lot. Also identified on the plans are the proposed wells and septic reserve areas on surrounding lots also proposed for the subdivision. No conflicts exist between the proposed septic system and well or the proposed septic systems and wells on adjacent lots. Drainage arrows and ground 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 ground surface on the lot in the area of the wells and septic systems is flat with only a very shallow grade to the northwest. The new well will be constructed in conformance with Municipal requirements. The new septic well will be constructed a minimum of 100' from all septic reserve areas proposed for the subdivision and all existing septic systems in the area. If the system is constructed in accordance with our design the following statements apply: The well, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. Lot 6, TI 6N R1 W Section 32 Proposed Lot 7, Inlet View Subdivision November 30, 2016 Page Two 2. The well, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. The well, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The well, 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.

Box 196650 Anchorage, AK 99519-6650 www.muni.org/onsite (907) 343-7904 Arsenic Advisory_ Certificate of On-Site Systems Approval # OSC 171273 A Certificate of On-Site Systems Approval inspection and test of potable water was recently conducted on the well water supply on Block , Lot 7 of Inlet Vue Estates Subdivision. This inspection revealed an arsenic concentration of 21.2 micrograms per liter (ug/L) for the property's well water sample. The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 ug/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells. Information on arsenic is available from the On-Site Water and Wastewater Program website (www.muni.org/onsite) or at 343-7904. This advisory must be attached to all copies of the subject Certificate of On- Site Systems Approval.
