CONSUL~'ANTS & GENERAL CONTRACTORS Nove~nber 5, 2012 Municipality of Anchorage Development Service Department On-Site Water & Wastewater Program 4700 Elmore Street P.O. Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Ref: Proposed Initial Septic System for Rabbit Creek Heights; Block 10H, Lot 3lA To whom it ma3, concern: The referenced property is currently vacant. The owner is proposing to build a 3 bedroom house that will be served by a private well and septic system. We are proposing to install a Quanics Aerocell treatment system on this property which includes the installation of a 1500 gallon S.T.E.P. tank and a dual 5-wide type drainfields. Two test holes were excavated on the property. The drainfield will be designed around the 30 foot radii of these test holes. Any area of the drainfield that is being installed within 5 feet of the testholes must be excavated out and backfilled with MOA approved sand and compacted. Comments regarding the design are summarized as follows: 1. SOILS: See the attached logs which show the soil classifications, groundwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. The primary drainfields have been designed around the 30 foot radius of testhole's 1 & 2. Testhole #1 has an application rate of 4 gal./day per sq. ft. Testhole #2 has an application rate of 0.5 gal./day per sq. ft. The minimum requirement if the entire drainfield was installed within this testhole would be 5 feet wide, 23 feet long, 0.5 feet of effective. Our proposed dual drainfields have approximately 34 feet of trench and 30 feet of trench in the 30 foot radius of teshole #1 and an additional 11 feet and 15 feet of trench within testhole #2. An average between the two application rates would be 2.25 gal./day/sq.k, which is still greater than our conservative approach on our design of lgal/./day/sq.ft. In short, the drainfield is adequately sized to serve the proposed 3 bedroom house as designed. 3. SURFACE WATERS: There are no surface water concerns. 4. TOPOGRAPHY & WAIVER REQUEST TO SLOPE GREATER THAN 25%: As can be seen on the attached topography drawing the topography runs southwest to northeast with an average slope of 20-25%. There is a slope greater than 25%, 43 feet from the proposed drainfield. We are requesting your department issue a waiver to the excessive slope. Per the owner/contractor, the proposed drive~vay will no~t create any additional cut banks (other than the one we are requesting a waiver too) with a slope greater than 25%. · We are installing a CAT III septic system which produces an effluent that is much higher quality than standard septic tank effluent. The system will be under a maintenance contract & inspected several 3701 E.

WAIVER TO NEIGHBORING FRENCH DRAIN: We request that your department issue a 35 foot waiver to the neighboring (Rabbit Creek View & Heights; Block 10H, Lot 32A) french drain. Justifications for the waiver are as follows; · We are installing a CAT III septic system which produces an effluent that is much higher quality than standard septic tank effluent. The system will be under a maintenance contract & inspected several times annually. · The soils in the area are tight increasing the level of treatment for all laterally migrating effluent. · Because of the natural topography (slopes running southwest to northeast) if effluent were to overflow its direct path to the drain would be greater than 50 feet. 6. WAIVER FROM 3:1 SLOPES TO 2:1 SLOPES: We request that your department waive the requirement for 3:1 slopes for a mounded system to 2:1 slopes. The mound and the slopes will be topsoiled and seeded in spring 2013. We are unaware of any adverse impacts this installation would have on adjacent wells or septic systems.
