SUBJECT: Lot 1A, Theresa Mae Subdivision No. 1 Septic System Permit Upgrade Permit No. SWO80039 We have changed the design for the absorption trenches for Lot 1A, Theresa Mae Subdivision to take advantage of better soils found on the lot. The new design includes 2-84' long by 5' wide by 4' effective depth absorption trenches at the location shown. The alignment of the trenches has also been changed to the northwest to southeast alignment to facilitate the additional length required. The surface slope on the lot is very shallow ranging from flat to 3% and the distribution line will be placed at 4' below the surface. The absorption area will remain in the percolation zones and not the organic layer. We verified during our first inspection the organic layer in Test Hole No. 1 does not exceed the 2' depth below the surface. No groundwater was found in either Test Holes No. 1 or 2. Additional percolation tests will be furnished verifying the soils encountered are as good or better than those utilized to design the absorption trench. ANDERSON ENGINEERING P.O.

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. Drainage arrows are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. The test holes placed on the lot in the area of the absorption trench and alternate site indicated silt with sand and gravel. The percolation rate of the soil was determined to be between 31 and 60 minutes per inch. Groundwater was found at a depth of 13' on May 20, 2006. 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 1,500 -gallon septic tank and 2-60' long by 3' wide by 7' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trenches will be 2.0' below the surface and the total depth will be 9.0'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank.' A flow splitter valve will be placed to insure even flow to each trench. The ground surface on the lot in the area of the absorption trench slopes to the northwest at constant grade approximating 3%. The new trench 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 all wells and any surface water and 10' the proposed and existing water services in the Lot 1A, Theresa Mae Subdivision April 9, 2008 Page Two 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. • s nc system, if constructed as designed, will nave no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.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. 5. Contractors installing wastewater disposal systems must be certified by the Municipal Division of Building Safety On -Site Water and Wastewater Program for system installations. Owners installing their own systems must receive prior approval from the On -Site Water and Wastewater Program before beginning system installation. SEPTIC TANK INSTALLATION 1. A new 1,500 gallon septic tank must be procured from an approved source and installed at the location shown. 2. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. Lot 1A, Theresa Mae Subdivision April 9, 2008 Page 2 of 3 3.

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 the distribution pipe must be perforated. 5.
