Box 196650 Anchorage, AK 99519-6650 Re: On-site Septic System Design Broadwater Heights Subdivision, Lot 3 Block 1 of Tract D To Whom It May Concern: A 3 -bedroom house is planned to be constructed on the 0.41 acre parcel described as Lot 3 Block 1 of Tract D in Broadwater Heights Subdivision. The property is located off Broadwater Drive in the Eagle River area. The property is not served by public water and sewer services. This document is to serve as a narrative for the on-site septic design we have prepared. Findings: Numerous test holes and borings were logged on this property. From our findings we established the southeast corner of the property as the only viable region to construct an on-site septic system. Steep slopes and less than 24 -inches of native unsaturated receiving soils limit other areas on the property from being developed. Soils in the southeast corner of the property were found to be 1 to 2 feet of topsoil, followed by 2 to 4 feet of poorly graded sands before reaching weathered bedrock. No groundwater was observed in any of the soil logs. A percolation test was performed in the immediate area of the proposed absorption areas and results show a percolation rate of 23 minutes per inch. Per Anchorage Municipal Code (AMC) 15.65.060.2.c at least 6 feet of vertical separation must be maintained from the bottom of the absorption area and bedrock. Imported fill will be required to reach this minimum separation. Combining with the additional fill being used for cover on the septic system the footprint of the import extends beyond the southern property line. A 50 -foot fill easement is proposed to legally facilitate this need. This pocket of developable land cannot be designed to meet the minimum standards for the Municipality of Anchorage (M.O.A.). Variances for slope setbacks and separation between the primary and reserve absorption areas will be required. 801 W. Firewecd Lane #1201 1 of 3 1365 E. Parks Highway #203 Anchorage, AK 99577 Wasilla, AK 99654 January 20, 2010 Variances: In reference to a memorandum issued by the MOA on April 7, 2004, absorption areas can be within 50 feet of slopes greater than 25%. This exception is only if the absorption areas maintain a 35 -Toot separation from the point of intersection for a 25% slope beginning 2.5 feet above the septic field's pipe invert and the finish grade. The proposed design meets this requirement to the south, but is within 15 feet of the >25% slope found to the west. From our field investigation we feel this reduced setback is viable because the bedrock was found to slope towards the southeast. Intuitively this means the natural subsurface drainage pattern would transport effluent in this southerly direction, eliminating concerns that the discharge would surface on the slope to the west. The area available for septic fields is not large enough to accommodate the primary and the reserve areas with the minimum 10 feet of separation. An additional variance is requested to reduce this separation to 5 feet. Factors for permitting this variance are based on the fact we are using a Category III Advanced Wastewater Treatment System which produces a cleaner effluent than more conventional septic systems. The need for imported fill for each septic field also ensures uniform soils are being used over the entire absorption area. We have also placed the reserve area up slope of the primary absorption area to limit infiltration. It is critical the contractor does not disturb the reserve area while they are installing the original septic field. Domestic Waste Water & Septic Design Calculations: Tank Size: 1,500 gal (Pre -fabricated fiberglass Advantex Tank w/ Orenco AX -20 Pod) • 1,000 gal. min. for 3 -bedroom house (AMC 15.65.50) Design: Daily Flow: 450 gpd (3 bedrooms x 150 gpd / bedroom) Percolation Rate: 23 min. per inch Application Rate: 4 gpd/s.f. (per AMC 15.65.350.F) Absorption Area: 450 gpd _ 4 gpd/s.f. =112.5 s.f. • Type of Septic Field: "5 -Wide" Shallow Trench • Width = 5 It • Depth =1 It • Reduction Factor = (W+2)/(W+1+2D) _ (5 ft+2)/(5ft+1+(2x1 ft)) = 7/8 = 0.88 • Length = (112.5 s.f. _ 511) x 0.88 = 20 ft Construction of New Septic System: As mentioned, this site does not constitute the design of a conventional on-site septic system. A category III system has been chosen and includes a 1,500 gallon fiberglass Advantex tank with an Orenco AX -20 pod which is prefabricated by Anchorage Take. The Advantex tank will be connected to a "5 -wide" shallow trench system with a center manifold. In order to meet the required 6 feet of vertical separation from bedrock over 3 feet of sand will need to be placed on the existing receivable soils before the absorption area is constructed. The trench will extend equal distances, 10 feet to the north and south of the manifold. The absorption area will consist of perforated distribution lines placed on top of 1 foot of filtering rock (3/4" to 1-1/2" washed rock). Monitoring pipes will be installed at the end of each trench, and cleanouts will be installed on the ends of each distribution line. Cleanouts shall be installed on the service lines going in and out of the septic tank. All pipes going in and out of the septic tank shall be installed on undisturbed native soils, or in trenches that have been adequately compacted. The bed will be filled with additional washed rock to ensure 2 inches of cover is maintained above the lines. Permeable geotextile fabric will then be installed over the washed rock to prevent fines in the backfill material from infiltrating and damaging the absorption system. Backfill shall be mounded a minimum of 6 inches above the surrounding grade to ensure positive drainage after settlement. Backfill over the absorption trench shall not be compacted. 901 W. Fireweed Lane #201 2 of 3 1365 E. Parks I lighwey #203 Anchorage, AK 99577 Wasilla, AK 99654 January 20, 2010 Maintenance of Septic System: Maintenance of this advanced wastewater treatment system will be the responsibility of the property owner. Regular servicing and appropriate use of the system should meet the manufacturer's recommendations and AMC 15.65.360. Using garbage disposals and flushing of non -degradable items (coffee grounds, cigarette butts, tampons, paper towels, etc.) should be avoided. The owner shall eliminate heavy surface loads in the area of the septic system to maintain the structural integrity of the system. Trees and other large plants should be removed and maintained at an adequate distance to prevent roots from growing into the system. Please contact me with any questions.
