The approved separation distance is 1.0 foot. This waiver approval applies to the existing on-sitewastewaterdisposal system to property line separation only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. If there are any further concerns or questions regarding this waiver, please call our office at 343-4744.

Box 196650 Anchomge, .Al~qka 99519-6650 Ref: Proposed Septic System Design for Lot 21, Block 4; Bruin Park S/D To whom it may concern: The existing 4 bedroom house is served by a private well and septic system. A test hole was excavated on the property where the proposed septic system upgrade will be located. The proposed septic system will be designed around the 30 foot radius of this test hole and a second test hole which will be excavated during construction. We are proposing that a 1250 gallon septic tank and a deep trench type dminfield be installed. Comments regarding the proposed design are summarized as follows: 1. SOILS: Attached is are 2 mil logs which show the soil pmfde, the groundwater monitoring, and the percolation test results. Test hole #1 was excavated just northwest of the house. Below the organics was a OM/GW layer to a depth of 11.5 feet which transitions to a SM layer to 16.75 feet (bottom of test hole). A percolation test was performed between 7.0 feet and 7.5 feet and found the rate to be 24 minute/ineE Another test hole was excavated on the lot to the south which confirmed that there are no bedrock concerns. Groundwater was not encountered during the excavation of the test holes. We are proposing that a confa'mation test hole be excavated during the installation of the septic system. 2. TRENCH DESIGN: a. Percolation Rate: 24 minutdineh b. Allowable Application Rate: 0.6 gallon/day/fl2 c. Number of Bedrooms: 4 d. D,e.s!gn Flow: 600 gallons per day _ e. Minimum Absorptinn Area: 1000 ft2 f. Maximum depth: 10.5 ft. g. Effective Depth: 6 ft. h. grdth: 2.5 ft. i. Length: 84 ft. k. Effective absorption area -- 1008 ft2 6901 Debarr Road, Suite 2B * Anchorage, AK 99504 Ph: (907)337-6179 * Fax: (907)338-3246 * Website: akwwc.com 3. SURFACE WATERS: Tberc are no surface waters within 100 feet of thc proposed upgrade. 4. TOPOGRAPItY: We are requesting a waiver for separation distances to slopes greater than 25 percent. We are proposing a trench to be greater than 35 feet from a slope greater than 25 percent. This slope is naturally vegetated and we foresee no chance of sewage daylighting. 5. LOT LINE WAIVER: We are requesting a I foot lot line waiver to the northem lot line. Lot 22, block 4 is undeveloped and will not be impacted by this encroachment. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systema. If you have any questions, please contact us at 337-6179. Thank you for your assistance.
