The percolation rate is rapid, but sufficient sand exists in the soil. This is a rural setting in the Eklutna Village. Some of the neighboring lots are developed. This site should not negatively impact any of the other area lots. The lot is relatively flat. Please review the wastewater system design for the single family home. I have included design plans & specs, design guidelines, & soil tests. If there is need for additional information or clarification please give me a call. Sincerely, `' t!5r v/ngEI Design Enclosures �2Th�IM ENGINEERING Munson S/D, Lot 2 SPECIFICATIONS & DESIGN GUIDELINES Wastewater System Sizing: The owner of lot 3 desires to develop lot 2. The plan is to build a 2 bedroom home on the property. The septic system will be sited near the lot 3 septic system. The owner is interested in converting the private well on lot 3 to a public well; this will require approval through DEC. The lot is about I acre in size. The lot to the south is vacant, as is the property to the east. The Eklutna cemetery is located to the west. No adverse impacts to neighbor lots are expected from this lot development. The lot slope is relatively flat throughout. One soil test was conducted. A sandy soil with a rapid percolation rate. An application rate of 1.2 GPD/FT2 with 0.5 reduction factor for utilizing a 5' wide trench was utilized. Specification Requirements: All components and work must comply with the Municipality of Anchorage Specifications (AMC) & State of Alaska Drinking Water Regulations and Wastewater Regulations. • Utilize the Existing Septic Tank.

Drain rock to be distributed uniformly throughout the trench. • Perforated pipe to be installed level with perforations down. • Silt barrier (filter fabric) to be installed above the drain rock. • Smeared trench sides must be raked or scarified before drain rock placement. • Backfill over drain rock must not be less than 36". • The finish grade must be mounded to promote drainage over the trench. • Insulation must be placed over any pipe installed under driveways or parking areas. • Approved pipe materials include cast iron, PVC ASTM D3034, PVC ASTM F789, ABS ASTM D2661, • Sewer Service Line is minimum 2% slope. • Septic Tank to be pumped every two years or when required. • Insulation board to be extruded direct burial polystyrene (Dow Styrofoam III or equal) Vll - ` Drly/Lte 3Y Proposed 2-Bdrn Hone rnate �^ Site 'nIQZ 04 3Q ESICN OTIIS: N , Tota D49 of Trench Is 5���' "est„Hole Elevation. 0 Q ,tiBf 0 i.,' rn flat. `w````.:t�7.to O pr 30.�QQ ,.\ `�'y Septic System Construction Q $lal Z.
