SUBJECT: Lot 25, Autumn Ridge Subdivision Permit No. SW03016 Revised Well Location We have revised the location of the well on the subject plan to prevent the removal of several trees. The new location is shown on the attached Site Plan. Placement of the well in this area will slightly impact the vacant lot to the south. The topography on that lot, however, dictates the house will be placed at the front of the lot with the septic system in the lower back area outside the well radius. "It appears the well can' be moved to the revised location without affecting the development of any lots in the area. ~ ,,6~,90.00 N Ill 71 L~ ~q2,,~' 9 )I¥~II4IIStZ \ \ \ February 3, 2003 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Lot 25, Autumn Ridge Subdivision Septic System Design and Permit Application Impacts to Adjacent Proj3erties Dear Onsite Services Engineer: The owner of Lot 25, Autumn Ridge Subdivision intends to construct a five-bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new well and septiC system to serve the new home on the property. The attached Site Plan and backup idocumentation identify the location and configuration of the new well and septic system and the parameters 'used in the design. Also identified on the plans are the alternate site, test hole locations and septic systems and wells on the surrounding lots. Drainage arrows are also shown and current drainage patterns will be maintained after construction. All components' of the septic system will be placed a minimum of 100' from wells in the area. The test holes placed near the location of the proposed and alternate absorption trenches indicated silty gravel and sand. The percolation rate on the material was measured at 34 minutes per inch. No ground water was found during placement of the test holes and none was noted during the monitoring period. We are therefore proposing to place a new 1,500-gallbn septic tank with two new 42' long by 3' wide absorption trench with 10' of gravel beneath the distribution pipe. The total depth of the trenches will be 12' below the surface with the distribution pipe at 2' below the surface. A flow splitter valve will be placed to assure even flow to each trench. Mounding over the trenches to provide 3' of cover will be required. The ground surface on the lot slopes at grades between 10% and 30% from west to east. The absorption trench will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 100' from the wells 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 L~3t 25, Autumn Ridge February 3, 2003 Page Two in the area or those to be constructed in the future. The system, if constructed as ~lesigned, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. e 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.

The total depth of the trench will be 12' below existing ground and the distribution pipe will be placed at .2' below the surface. A flow splitter valve 'must be placed to insure even effluent flow to each trench. All components 'of the new absorption trenches and septic tank must be constructed a minimum of 100' frOm the proposed well on the lot and on adjacent lots. A minimum of 4' of cover is required over,the septic tank and 3' over the absorption trench. In lieu of cover2' of direct bury insulation and 2' of cover may be placed. 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. e 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. A new 1,500-gallon septic tank must be procured from a certified septic tank manufacturer. e 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 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 budal insulation. Lot 25, Autumn Ridge Subdivision February 2, 2003 Page 2 of 3 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: 1. The draintield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. 2. 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. m 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. Se 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. e Grade area surrounding the absorption trench 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.E. (perforated, but not solid) and ASTM D2662 or A.B.S. (perforated and solid). Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Co. Styrofoam HI or equal).
