H~,~,, ty ut ~ , ~ta~On e. . ~je The owner of Lot 10, Block 3, Sky Hills Subdivision has decided to construct a five bedroom home on the lot. Our previous application for tun onsite septic systmn construction pmrnit was for a four bedroom home. We have therefore modified the pertinent pages of the design to reflect the five bedroom home and have changed the permit application to reflect five bedrooms. Please switch the attached pages with their counterparts previously submitted and issue the permit for a five bedroom home. Thank you for your assistance with this matter. April 26, 1999 Municipality of Anchorage Department of Health and Human Services 825 "L" Street Anchorage, AK 99502-0650 Subject: Lot 11, Block 3, Sky Hills Subdivision Septic System Design Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 11, Block 3, Sky Hills Subdivision intends to construct a five bedroom home on the lot. We are therefore requesting a permit to construct a septic system on the lot to serve the house. The subdivision is served by the Municipal water system so a well permit is unnecessary. The attached site plan and backup documentation describe the proposed system and show the location of the new system. The testholes placed on the property revealed poorly graded silty sands which percolated at rates between 18 and 22 minutes per inch. Groundwater was not encountered during the excavation nor was any noted during the monitoring period. We have therefore designed a deep absorption trench with 9' of gravel beneath the distribution pipe. The trench will be 70' tong with a total depth of 12'. The ground surface on the lot slopes to the east from the proposed house location at a rate approximating 5%. This is the area of placement for the absorption trench. The trench will be constructed perpendicular to the slope. No conflicts exist with other lots in the area where septic systems have been or will be constructed. All segments of the new system will be constructed a minimum of 10' from the water service line and 10' from all lot lines. 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 fu[ure. The subdivision is currently served by a community water system. 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. Lot 11, Block 3, Sky Hills Subdivision April 26, 1999 Page Two The system, if constructed as designed, will have no adverse impact on reserved 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. ']'he current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

DATE: ~/~,*~ ON-SITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION AND MATERIAL SPECIFICATIONS SUBJECT: LOT 11, BLOCK 3, SKY HILLS GENERAL: The scope of this project includes the procurement and placement of a new 1,500 gallon septic tank. It also includes the construction of a new 70' long x 3' wide x 9' effective depth absorption trench at the location shown on the attached Site Plan. The total depth of the trench will be 12' below existing ground. Mounding over the trench may be required to provide a minimum of 3' of protective cover. Constructien 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. The Contractor shall be responsible for obtaining all underground utility locates and for the layeut of the septic system and verification of the location of all lot lines. 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. Contractors installing wastewater disposal systems must be certified by the Municipal Department of Health and Human Services for system installations. Owners installing their own systems must receive prior approval from D.H.H.S. before beginning system installation. SEPTIC TANK INSTALLATION 1. The 1,500 gallon septic tank must be procured from an approved source and installed at the location shown on the plans. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access, 3. The septic tank shall be sufficiently bedded to ~revent settling or shifting of the tank. 4. Ail standpipes on the septic tank shall extend a m~nimum of 12 inches above final grade. 5. Tanks installed without 4' of cover shall have a minimum of 2" of direct burial insulation. A foundation cleanout shall be installed one to four feet from the building foundation. Two cleanouts are required between the tank and the drainfield. Lot 11, Block 3, Sky Hills Subdivision April 26, 1999 Page 2 of 3 7. Final grading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: 1. The drainfield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. Distribution piping must be placed level with perforations down atop a level bed of drainfield rock. Rock should then be placed over the pipe to provide a minimum of 2" of cover. 3. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 4. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below ground must be perforated. Contractor shall verify the septic tank and drainfield are a minimum 100' away from any private water wells in the area, 150' from a Class "C" Well or 200' from any community well. Direct bury insulation must be placed over the distribution system if less than 3' of backfill depth is available. Finish grade over the trench must be mounded to prevent settlement or depressions. 7. Grade area surrounding the absorption trenches to drain away. A minimum 2' of accepting soil is required below the drainfield rock for a 5' wide trench. Contractor shall verify this condition prior to placement of the rock. All pockets of unacceptable materials must be removed and replaced. MATERIAL SPECIFICATIONS: 1. Septic tanks must be constructed by a Municipally approved septic tank manufacturer. 2. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Cast Iron (perforated and solid), ASTM D3034 or P.V.C. (perforated and solid), ASTM F810 or H.D.P.F!. (perforated, but not solid) and ASTM D2662 or A.B.S. (perforated and solid). 3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Co. Styrofoam HI or equal). 4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). Lot 11, Block 3, Sky Hills Subdivision April 26, 1999 Page 3 of 3 5. A permeable geotextile fabric (Typar, Mirafi or equal) must be installed between the final drain rock layer and the native soil layer. 6. All drain rock shall be .5" to 2.5" in diameter with less than 3% passing the #200 sieve. INSPECTIONS: A minimum of two inspections are required by Municipal Ordinance. 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.
