RECEIVED BY: I~ '~'~ DATE: PATE.' July 16, 1996 Municipality of Anchorage Department of Heath & Human Services 825 "L" Street Anchorage, AK 99502-0650 Subject: Lot 1, Vons Subdivision Septic System Design Impacts to Adjacent Properties Dear On Site Services Engineer: We hereby apply for a permit to construct a new well and septic system on the subject lot. Testholes placed on the lot indicate soils suitable for the placement of an absorption trench. The upper two feet of the effective area of the trench percolates at a rate of 2.4 minutes per inch. The remaining three feet of area percolates at a rate of 46 minutes per inch· The weighted average absorption rate for the effective area is .73 gallons per square foot per day. The trench has been designed using this average rate. No groundwater was encountered during the excavation of the testholes and none has been noted during the monitoring period. We do not anticipate the bottom of the trench will be within 4' of the groundwater table at any time of the year. The attached site plan indicates the area for the absorption trench and the alternate site. The ground surface of the lot slopes from south to north at a variable rate from 2% to 6%. If the new system is constructed as designed the following statements can be made: 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 subdivision is currently served by a community water system. 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 reserved space, either surface or subsurface, on any lots located in the area. Sincerely, Michael E. Anderson, P.E. Attachments The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The ourrent drainage pattern will be maintained.

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. 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. 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 A new 1,000 gallon septic tank must be procured from an approved source and installed at the location shown on the Site Plan. Lot 1, Vons Subdivision July 18, 1996 Page Two A septio 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 prevent settling or shifting of the tank. 4. All standpipes on the septic tank shall extend a minimum 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. 7. Final grading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: 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. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below ground must be perforated. Lot 1, Vons Subdivision July 18, 1996 Page Three 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 trench to drain away. A minimum 2' of accepting soil is required below the drainfield rock. 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.E. (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 watertight couplings (Caulder, Fernco, or equal). with A permeable geotextile fabric (Typar, Mirafi be installed between the final drain rock native soil layer. or equal) must layer and the Lot 1, Vons Subdivision July 18, 1996 Page Four 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. MEMORANDUM RECEIVED DATE: TO: FROM: October 12, 1996 Jim Williams, MOA- DHHS Mike Anderson, P.E. ~ ~ OCT '1 4 1996 Municipality of Anchorage Dept, Health & Human Services SUBJECT: Lot 1, Vons Subdivision Permit No. SW960222 Proposed Well Location The terrain on the subject lot is too difficult to traverse for the well drilling rig to place the proposed well at the location shown on the site plan originally submitted with the permit application. We are therefore requesting the location of the well be placed as shown on the attached revised site plan. Our investigation of the lot reveals no conflicts with septic systems in the area. The 100' protective radius from the well is easily maintained. Septic systems on adjacent lots do not conflict with the 100' radius. In addition, both the septic system and reserve system on this lot are more than 100' from the proposed well location. Please revise the original permit to show the new location of the well. Thank you for your time and consideration with this matter. SITE PLAN SCALE 1" = 40' ' OCT. 14 t99~ " Dept, HealU I.
