A permit was issued for the construction of a well and septic system for Lot 16, Block 5, Riverview Estates Subdivision in May of 1998. The permit subsequently expired and the property changed hands. The current owner of the property intends to construct a three-bedroom home on the lot. We are therefore requesting the permit be reissued for the construction of a new well and septic system to serve the home. The attached Site Plan and backup documentation identify the location and configuration of the new well and septic system and the parameters used in the original design. Also identified on the plans are the location of the well on the lot, test hole locations and the locations of existing wells and septic systems in the area. Since the original permit was issued both the lot to the south and to the northeast have been developed. The locations of the wells and septic systems on these lots have been added to the drawings. The test holes placed near the location of the proposed absorption trenches and alternate site indicate slightly silty gravel with a percolation rate of less than 3 minutes per inch. Groundwater was found during the placement of the test holes and was monitored during the high water period. We are therefore proposing to place 2 - 5' wide by 27' long by 2' effective depth absorption trenches on the property. The total depth of the trench will be 4'. The distribution pipe will be placed at 2' below the ground surface to provide sufficient separation from groundwater. The ground surface on the lot slopes as shown on the attached Site Plan with moderate slopes east to west. The new absorption trenches will be constructed In conformance with Municipal requirements and parallel to ground contou ,rs, where possible. All components of the new septic system will be constructed a m~n~mum of 100' from the well on the lot and those In the area and 10' from the service line from the well to the house. If the system is constructed in accordance with our design the following statements · Lot 16, Block 5, Riverview Estates May 29, 2002 Page Two apply: i. 2. 3. 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. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattem will be maintained. Sincerely, Michael E. Anderson, P.E.

Construction shall be in accordance with the approved site plan and 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 any necessary underground utility locates. Unless specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed fi'om soil settling. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mound area. Contractors installing wastewater disposal systems must be certiffed by the Municipal Health Department for system installations. Owners installing their own systems must also receive prior approval from the Municipal Health Department. SEPTIC TANK INSTALLATION: A septic tank is to be constructed by a certiffed septic tank manufacturer. Construction shall include two 4" cleanouts for pmnping access. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. All standpipes on the septic tank shall extend a miuimum of 12 inches above final grade. 4. Septic tanks installed with less than 4 ft. of cover shall be insulated. 17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASKA 99577 Page Two Lot 16, Block 5, Riverview Subdivision April 17, 1998 A foundation cleanout shall be installed one to four feet fi'om the building foundation. In the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10 ft. from the tank. The first cleanout, in line, shall be to clean toward the leachfield. The second cleanout shall be to clean towm'd the septic tank. Final grading over the septic tank shall be such that a positive slope exists axvay from the septic tank. ABSORPTION TRENCH/DRAINFIELD INSTALLATION: Excavate the proposed trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level. If the sidewalls of the excavation become smeared, they must be raked or scratched (ruffed-up) before gravel (sewer rock) placement. Once the gravel is installed, the distribution pipe is to be installed level with the perforations faced downward. Gravel is then to be placed over the distribution pipe to provide a minimum of 6 inches of cover over the pipe. A silt barrier must be installed between the final gravel layer and the native soil backfill. Ensure the silt bmTier covers the entire gravel surface before placing backfill. Monitor tubes shall be of four (4) inch diameter, installed approximately in the locations shown on the design, and extend a minimum of 12 inches above final grade. The portion of the monitoring tube extending through the gravel shall be perforated fi'om the bottom of the trench to the invert of the distribution pipe. This is equivalent to the effective depth of the gravel as noted on the design. Backfill over the final gravel layer must not be less than twenty-four (24) inches. Insulation must be installed when the backfill depth is less than thirty-six (36) inches. The finish grade over the trench must be mounded to prevent the formation of a depression after settling. MINIMUM MATERIAL SPECIFICATIONS: Any septic tank proposed for installation must be constructed by a Municipal approved septic tank manufacturer. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Page Three Lot 16, Block 5, Riverview Subdivision April 17, 1998 Type of Pipe Perforated Solid Cast Iron Yes ASTM D3034 (PVC)' Yes ASTM F810 (HDPE) Yes ASTM D2662 (ABS) Yes Yes Yes No Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). A pe~rneable nontoxic silt barrier (Typar 3401, Mirafi 140N, or eqnal) must be installed between the final leachfield gravel layer and the native soil backfill. All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the #200 sieve. When sand is being used as a filter material, its gradation specifications must conform to CUlrent M.O.A. or D.E.C. requirements, which ever requirement applies. INSPECTIONS: Typically there will be a minimum of thi'ee (3) inspections required during the installation of the wastewater disposal system. These inspections will occur as follows: The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled before this inspection. The second inspection must be conducted after the placement of the silt barrier, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other backfill. 3. The final inspection is to occur upon final grading of the property. Page Four Lot 16, Block 5, Riverview Subdivision April 17, 1998 Often there will be more than these 3 inspections required. Especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting engineer is to be contacted at least 24 hours prior to the start of construction. If necessary, a pre-construction meeting will take place on-site. The inspecting engineer will not coordinate, direct or control in any way the contractors activities. The owner shall contract with the contractor to perform the work outlined in these specifications and plans and in accordance with the attached M.O.A. pernfit. There will be no contractual arrangement existing between the contractor and S & S Engineering.
