The attached site plan identifies the location of the home and septic location. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. We are proposing building the new trenches in the same place specified in the original permit for the alternate site. The ground surface on the lot slopes very mildly down from the road at about a 5% slope before dropping away sharply to between 35-45% slopes. There are slopes greater than 25% within 50’ of the site, but none greater than 46% within 100’. The trenches have been designed to meet the steep slope criteria of 15.65.210.B.4. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. The properties in this neighborhood are all on community water, so there are no conflicts with wells. Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

The owner of Lot 8, Block 4, Tablelands Subdivision intends to construct a new four- bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The subdivision is currently served by a community water system. No conflicts exist with adjacent septic systems or wells and the proposed septic system on this lot. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system and alternate site. The current drainage pattern is identified on the Site Plan. The drainage pattern will be maintained after development of this lot is complete. Test holes recently placed on the lot indicated silty gravel in the area of the absorption trenches. The accepting soils were tested and found to have a percolation rate of 31 to 60 minutes per inch. No groundwater was found in either test hole during placement but was noted at 14' below the surface during the monitoring period. Our design includes the placement of a new 1,250 -gallon septic tank along with 2 - 67' long by 5' wide by 4' effective depth absorption trenches to collect and treat the sewage generated in the house. The bottom of the trench will be 6' below the surface. The distribution pipe will be 2' below the surface. A flow splitter valve will be placed to assure even flow to each trench. A minimum of 3' of cover will be placed atop the trenches and a minimum of 4' of cover will be placed atop the new septic tank. The ground surface on the lot slopes at shallow grades from west to east as shown on the Site Plan. The absorption trenches will be constructed parallel with the slope of the ground surface as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 10' from the water service proposed Lot 8, Block 4, Tablelands Subdivision January 24, 2005 Page Two for the lot and on adjacent lots. It will also be constructed a minimum of 100' from any surface 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, /� J Michael E. Anderson, P.E.

ANDERSON CERTIFY THAT THIS WAS PERFORMED IN ACCORDANCE WITH ALL STATE AND MUNICIPLE GUIDELINES IN EFFECT ON THIS DATES __ _ _ 1/24/2005 ONSITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION AND MATERIAL SPECIFICATIONS SUBJECT: LOT 8, BLOCK 4, THE TABLELANDS SUBDIVISION GENERAL: The scope of this project includes the procurement and placement of a new 1,250 -gallon septic tank at the location shown on the site plan. Work also includes the construction of 2 new absorption trenches each 67' long by 5' wide with 4' of drainfield rock beneath the distribution piping also at the location shown on the Site Plan. The total depth of the trenches will be 6' below existing ground and the distribution pipe will be placed at 2' below the existing ground surface. A Bull Run Flow Splitter Valve must be installed to assure equal flow to each trench. All components of the new absorption trenches and septic tank must be constructed a minimum of 100' from any surface water and 10' from the water service lines on this and adjacent lots. A minimum of 4' of cover is required over the septic tank and 3' over the absorption trenches. In lieu of cover 2' of direct bury insulation and 2' of cover may be placed. 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 is also responsible to assure the separation distance from wells and surface water in the area is maintained. The engineer will accept no responsibility for Contractor errors. 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. Lot 8, Block 4, The Tablelands Subdivision January 24, 2005 Page 2 of 4 SEPTIC TANK INSTALLATION 1. A new 1,250 -gallon septic tank must be procured from a certified septic tank manufacturer. 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.
