A site visit was conducted and other than the house being built, there have been no substantial changes to this lot or to the surrounding area since the permit was originally issued. The current design and permit conditions meet all code requirements. We therefore request the renewal of the permit for the well and septic system on this lot. Sincerely, Michael E. Anderson, PE 11.20.20 PO BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 (FAX) November 19, 2020 MOA Development Services Dept, On-Site Water & Wastewater Program 4700 Elmore Rd Anchorage, AK 99507 Subject: The Cascades, Tract A – NHN West River Drive Septic System Design Dear On-Site Services Engineer: The owner of the above lot intends to build a 4-bedroom home on the property. We are submitting this permit application for the construction of a new well and septic system to serve the home. The attached site plan identifies the location of the home and the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system on this lot or adj acent lots. The ground surface on the lot slopes to the northeast at grades approaching. There are no slopes greater than 25% within 35 feet downslope of either the primary or alternate site. Field measurements indicate the slopes exceed 25% at 44’ from the edge of the proposed absorption trench. Ground surface contours are shown on the site plan indicating the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. The absorption trench will be constructed utilizing engineered receiving soils in conformance with Section 15.65.210D3c and the attached design documents. The absorption trench will be utilized in association with an Advantex Treatment System with an AX-20 pod and pump vault. The system will be 50’ from the well on this and adj acent lots. Please refer to the attached test hole logs, soils lab analysis, plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adj acent properties.

BOX 6898 JBER, AK 99506-0898 November 3, 2020 Regulatory Division POA-2020-00469 Colony Builders, Incorporated Attention: Mr. William F. Taylor 9420 Vanguard Drive Anchorage, Alaska 99507 Dear Mr. Taylor, This letter responds to your September 28, 2020, request for a Department of the Army (DA) jurisdictional determination for Tract A of Cascade Subdivision in Eagle River. It has been assigned number POA-2020-00469, South Fork Eagle River, which should be referred to in all correspondence with us. The subject parcel is located on West River Drive in Eagle River, Alaska, at Latitude 61.2427º N., Longitude 149.4632º W. Based on our review of the information you provided and our October 2, 2020, site visit, we have determined that although the subject property may contain waters of the United States (U.S.), including wetlands, the proposed home construction project would take place within the parcel’s uplands, and would not involve a discharge of fill material into waters of the U.S. Therefore, a DA permit is not required. However, a permit may be required if you alter the method, scope, or location of your proposed work. You should contact us if you make changes to your project. Section 404 of the Clean Water Act requires that a DA permit be obtained for the placement or discharge of dredged and/or fill material into waters of the U.S., including jurisdictional wetlands (33 U.S.C. 1344). The Corps of Engineers (Corps) defines wetlands as those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Section 10 of the Rivers and Harbors Act of 1899 requires that a DA permit be obtained for structures or work in or affecting navigable waters of the U.S. (33 U.S.C. 403). Section 10 waters are those waters subject to the ebb and flow of the tide shoreward to the Mean High Water Mark, and/or other waters identified by the Alaska District. -2- Nothing in this letter excuses you from compliance with other Federal, State, or local statutes, ordinances, or regulations.
