We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the locations of the existing wells on adjacent lots in the subdivision. No conflicts exist between the proposed septic system and those on adjacent lots. Drainage arrows are shown indicating the surface slope of the property in the area of the new septic system. Test holes were placed on the lot in the area of the absorption trench and alternate site, which indicated a silty gravel with some sand (GM/SM) material.. The percolation rate of the materials was determined to be 5 to 49 minutes per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. An application rate of .45 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 2,000 -gallon septic tank and 2-63' long by 3' wide by 8' effective depth absorption trenches to treat and dispose the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 4' below the surface and the total depth will be 12'. A minimum of 3' of fill will be placed over the absorption trenches and 4' over the septic tank. A flow splitter valve will be installed to assure even flow to each trench. The ground surface on the lot in the area of the septic system slopes gently to the southeast. The new trenches will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from the proposed and existing wells and any surface Lot 6, Autumn Ridge October 23, 2005 Page Two water 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 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, -0� Ea L' Michael E. Anderson, P.E.

Work also includes the construction of 2 new 63' long X 3' wide X 8' effective depth absorption trenches at the location also shown on the Site Plan. The distribution line in the trenches will be placed at 4' below the existing ground surface. Total depth of the trenches will be 12' below the existing ground surface. The new absorption trenches and septic tank must be placed a minimum of 100' from the well on this lot and in the area and 10' from the water service line proposed for the lot. A minimum of 100' must separate any surface water in the area and the septic tank and absorption trench. A minimum of 3' of cover is required over the absorption trench and 4' of cover over the septic tank. A flow splitter valve must be placed to insure even flow to each trench. 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 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 2,000 -gallon septic tank must be procured from an approved source and installed at the location shown. Lot 6, Autumn Ridge October 23, 2005 Page 2 of 3 2. 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 burial insulation. 6. 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 drainfield 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. 5.

Box 196650 Anchorage, Alaska 99519-6650 Ref: Proposed Well and Septic System for Lot 6, Autumn Ridge Subdivision To whom it may concern: The proposed 5 bedroom house will be served by a private well and septic system. Three soils logs were excavated on the property and logged by Michael E. Anderson, P.E. We are proposing that a 1500 gallon septic tank be installed and also a deep trench type drainfield be installed within the 30 foot radii of TH-14 & TH-15. Comments regarding the design are summarized as follows: I. SOILS: Attached are the logs which shows the soil classifications, groundwater monitoring, and the percolation test results. It is our opinion that an application rate of 0.6 gallons/day/ft2 should be used. 2. TRENCH DESIGN: a. Percolation Rate: 49 & 5 minutes/inch b. Allowable Application Rate: 0.6 gallons/day/ft c. Number of Bedrooms: 5 d. Design Flow: 750 gallons per day e. Minimum Absorption Area: 1250 ft2 f. Total Depth: 12 feet (max.) g. Effective Depth: 8.5 feet h. Width: 2.5 feet i. Reduction Factor: N/A j. Minimum Length: 75 feet long k. Effective absorption area =1275 ft2 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed septic system. 6901 Debarr Road, Suite 2B * Anchorage, AK 99504 Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: akwwc.com 4. TOPOGRAPHY: As can be seen on the attached topography site plan and design drawing, the proposed trench is to be installed in an area where there are no slope concerns. The trench is to be installed parallel to slope contours. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact us at 337-6179. Thank you for your assistance. P.E., M.S. NOTE: Attached is a site plan drawing, a design drawing, a topography site plan, three soils logs, and a 7 page construction specification letter which are all part of the design package for this septic system. 6901 Debarr Road, Suite 2B * Anchorage, AK 99504 Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: akwwc.com OT 12 \ C HOE S/D \ 1 \ LOT 11 c t I I I ' COHOE S/DLOT I U WI COHOE S/D I?i LOT 1 O / COHOE S/D / Qi / LOT 2 COHOE S/D $ JJ LOT 9 3 i S/D i 4 S/D LOT 5 COHOE S/D LOT 11 AUTUMN RIDGE QR \ LOT 4 \ AUTUMN RIDGE 010 TH027 LOT 5 v AUTUMN RIDGE PROPOSED / tti-120 5 BEDROOM COHOE S/D PROPOSED SEPTIC SYSTEM 0TH -13 ��---^----�I LAT 8 (SEE DESIGN, 11 L-..
