We are requesting a permit be issued for the construction of a new well and septic system to accommodate the new 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. The subdivision was only recently platted and the lots on all sides of this lot are currently undeveloped. No existing or proposed wells or septic systems are within 100' of the proposed systems. Drainage contours 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 hole placed on the lot in the area of the absorption bed indicated the presence of silty sand (SM). The percolation rate of the material was determined to be 31 to 60 minutes per inch. Groundwater was found during the placement of that test holes and rose to 3' below the surface during the monitoring period which included May 15, 2013 and 2014. All test holes on the lot are currently dry. An application rate of 2 gallons per day per square foot was used in the design of the absorption system. An Advantex Treatment System designed for a four bedroom home will be placed on the lot including a 1,500 gallon tank with an AX20 Filter Pod along with a pump vault. Effluent will be discharged into a 20' long by 15' wide absorption bed. The distribution line in the bed will be placed at 1.5' above the surface. Existing organic material will be removed to 1' below the surface and replaced with MOA approved coarse sand to 1' above the existing ground surface where drainfield rock will be placed. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption bed and 4' over the septic tank. Lot 3, Woodhaven Subdivision No. 3 March 23, 2017 Page Two The Advantex Tank will be placed in groundwater which may be as high as 3' below the surface. An anti buoyancy collar will be required. The size of the collar and placement location are shown on the Orenco Tank Burial Details (attached). These details will be followed during the placement of the tank. In addition a footing drain will be placed around the house. This drain will be less than 50' from the new absorption bed. We hereby request a waiver allowing the use of the new code which requires a subsurface drain to be twice the effective depth or 10' from the edge of the absorption bed. The drain is much more than 10' from the edge of the proposed bed. The ground surface on the lot in the area of the absorption bed slopes at a shallow grade to the west. The new bed 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 area. If the system is constructed in accordance with our design the following statements apply: 1. 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, 274CA� Michael E. Anderson, P.E.

ANDERSON CERTIFY THAT THIS WAS PERFORMED IN ACCORDANCE WITH ALL STATE AND MUNICIPLE GUIDELINES IN EFFECT ON THIS DATE: 4/5/12 Step 8. Add Antibuoyancy Collar, (if Necessary) Follow the directions below to make a concrete -and -reinforcing mesh (remesh) antibuoyancy collar. The collar provides sufficient ballast for the tank even if there is groundwater to grade. • The collar is 18 inches (460 mm) wide x 6 inches (150 mm) thick with a 12 -inch (305 -mm) width of remesh in the center. • The collar requires about 2 cubic yards (1.5 cubic meters) of concrete with a minimum compressive strength of 2500 psi (17.23 MPa). • The collar's width — not its weight — provides the necessary antibuoyancy. Step 8a: Make a backfill dam around the tank to use as a form. The form should be 6 inches tall by 18 inches wide It 50 mm by 460 mm). • Width is measured from the outside tank wall above the midseam flange. Step 8b: Pour a 3 -inch (75 -mm) lift of concrete into the form around the tank. Step 8c: Place a continuous 12 -inch (305 -mm) width of remesh around the tank, on top of the concrete. • Remesh can be 6 x 6 -10/10 WWF or 6 x 6 - W1.4 x 1.4 (152 x 152 MW9.1 /9.1). Step 8d: Pour a second 3 -inch (75 -mm) lift of concrete on top of the remesh Step 8e: Allow the concrete to set for a minimum of two hours (or longer, if possible) so that it's hard enough for the final backfill. Note: An 18- x 12 -inch thick collar (460- x 305 -mm) can be used in place of the concrete and remesh collar. This requires about four cubic yards (3 0) of concrete. Step 9: Connections and Backfilling to Final Grade Step 9a: Before final backfill, be sure to make all tank plumbing connections. • Make sure Inlet and outlet pipes are supported by a compacted base. Step 9b: Backfill a 24 -inch (610 -mm) layer of fill material around the tank. • Don't backfill with sand. • Don't use native fill that is primarily sand; very soft or highly expansive clay; peat or muck; or if it contains debris, large rocks (> a/ -in. or 19 -mm) or sharp rocks. • If native fill material isn't usable, use s a/ inch (s 19 mm) rounded gravel, crushed stone, or pea gravel as fill material. It should be washed, free- flowing, and free of debris. • If you're using Plowable concrete, layering and compacting aren't necessary. Step 9c: Use a mechanical compactor to thoroughly compact the fill. • If a concrete antibuoyancy collar has been poured on the same day as you are backfilling, compact the backfill gently to avoid damaging the collar. Step 9d: Add and compact fill material in 24 -inch (610 -mm) lifts to final grade. • Make sure the tank access risers extend a minimum of 3 inches (75 mm) above final grade to ensure proper drainage away from the risers. �¢ Backfill dam 0.. °1U i.' o b9� •g 12 -inch (300 -mm) 'o 18 in. wide '• 3: ? .
