Box 196650, Anchorage, AK 99519-6650 (907)343-7904 Ref: Response to Submittal Comment Sheet for Paradise Valley S1D; Block 9, Lot 30 Ms. Carroll, The following is a list of your comments followed by our response to those comments: 1. Confirm Block 9 Lot 7 is vacant and label accordingly on sire plan. — Based upon our records research, the property still appears to be vacant. 2. Confirm existing cabin on lot will be demolished or size septic for additional bedroom(s). — According to the owner, the cabin on the property does not have any existing water or sewer service and it will not be connected to the sewer system. It his intent to leave the cabin in place and demolishing the cabin should not required. 3. Proposed well location and separation requirements may prohibit future residential use of Lot 29. Please address. — The proposed well location was requested by the owner due to not wanting to run a long water line from the well to the new house. In order to minimize the impact on Lot 29, we have revised the site plan and design drawings to show a new well location. If during drilling of the well the owner has issues with this well location as shown, the well driller and owner will work directly with your department to revise the location. 4. Test hole is less than S feetfr-om bed. Please address. — Test hole #3 was excavated over 3 years ago. Any settling concerns with the excavation of this test hole is most likely not a concern and since we are installing 4.5 feet of sand filter, the 5 foot separation to the test holes should not be a concern. 5. Under "Drainfield Design "for both proposed and alternate site, clay fir 3' maximum depth is 3' maximum excavation depth. — We have revised this to show that the maximum excavation depth is 3 feet from the highest point. 6. Test hole TH#2 is within 30 feet of the alternate site. Use higher pert rate of TH#2 for design of alternate site. — Test hole #2 had percolation rates of 2.7 minutes/inch between 1.5 to 2.5 feet and 10.9 minuteslinch between 5 to 6 feet. We have revised our design to reflect this. According to the table under AMC 15.65.350, a Cat II advanced wastewater system with percolation rates 3701 East Tudor Road, Suite 101 *Anchorage, Alaska 99507-1259 Phone: (907) 337-6179' Fax: (907) 338-3246' Website: www.garnessengineering.com Page 2 of 2 between 6-15 minutes/inch only requires a 3.0 gpd/sq.ft. application rate. Based upon this, our design shows the correct application rate. There is less than 2 feet of native accepting soil between bottom of in-oposed field and seasonal high ground water level. If intent is to provide ERS, request waiver and address that new code requires AWWTS. — The 3 foot seasonal high groundwater on 10/10/2013 has only occurred once that we are aware of and was recorded during one of the highest recorded rainfalls in the month of October. Per our conversation between GEG employee, Jody Maus and Graham MacConald, the owner, he has stated to us that he has taken groundwater readings and has never seen the water at this level. However, we have designed the drainfield around this high groundwater level reading. It is our intent to provide an ERS and we are requesting a waiver to allow an ERS and not require an AWWTS. It is our opinion that a mound system using a sand filter is technically an ERS system and does not require an AWWTS system. We have revised the application to show the request for this waiver. 8. Address tank buovancv. — We have placed a note on the drawing that states there must be 4 feet of classified fill (unsaturated) placed over the septic tank to counteract buoyancy forces; however, we request that the record drawings include buoyancy calculationbased upon the actual conditions encountered during the installation. �D 9. Extent of mound does not appear correct on plan. Please address. —The neighboring septic system is mounded and the utility easement has had fill placed over it to the property line. The proposed extent of the mound has been modified on our design to show that the fill will extend to the property line and end at the property line up against the existing fill that has been previously placed there. 10. There is less than � feet ofcover at corners ofproposed field. Please address. — We have revised the detail drawing to show et of cover at corners of the proposed drainfield.

Box 196650, Anchorage, AK 99519-6650 (907)343-7904 Ref: Proposed Well and Septic System for Paradise Valley S/D; Block 9, Lot 30 To whom it may concern: The proposed 2 bedroom house is to be served by a private well and septic system. We are proposing that a 1500 gallon S.T.E.P. tank and a mounded bed type drainfield be installed. Three test holes were excavated on the property. The drainfield will be designed around the 30 foot radius of test hole #3. Comments regarding the design are summarized as follows: 1. SOILS: See the attached logs which shows the soil classifications, groundwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications 3. SURFACE WATERS AND WETLAND ISSUE: There are no surface waters within 100 feet of the proposed septic system. During our research on this property, we reviewed the MOA wetland mapping and found that a large portion of the property is located in a "potential wetland". We discussed this matter with Deb Wockenfuss and she recommended we contact Thede Tobish, MOA Senior Planner regarding this issue. Mr. Tobish reviewed this parcel and responded that this area may have some potential wetlands and that the Corp of Engineers (COE) should be contacted to have a Pre -Jurisdictional Determination performed for this property. We have attached a copy of the email correspondence for your review. We have contacted the owner regarding this issue and he is contacting the COE about this issue. Once he resolves this issue, we will provide you a copy of their report. 4. TOPOGRAPHY: As can be seen on the attached topography site plan and design, the average slope in the area is approximately 10-15% percent running east to west. There is a large enough bench where the proposed bed will be installed that has slope less than 10 percent (-7%). Attached are some pictures that were recently taken showing this benched area just below Test Hole #3. We have attached a profile drawing of the proposed drainfield which shows the proposed construction of the drainfield. The drainfield and reserve site will be located over 50 feet away from all slopes exceeding 25%.

BOX 6898 JBER, AK 99506-0898 September 14, 2016 This letter responds to your September 6, 2016, request for a Department of the Army (DA) jurisdictional determination for your parcel. It has been assigned number POA -2016-467; Potter Creek, which should be referred to in all correspondence with us. The project site is located within Section 11, T. 11 N., R. 3 W., Seward Meridian; USGS Quad Map Anchorage A-8; Latitude 61.05541 N., Longitude 149.77131 W.; Municipality of Anchorage, Paradise Valley Subdivision, Block 9, Lot 30; Parcel 020-414-21-000; in Anchorage, Alaska. Based on our review of the information you provided and our September 13, 2016 site visit, we have determined the subject property does not contain waters of the United States (U.S.) under Corps jurisdiction. Therefore, a DA permit is not required. A copy of the Approved Jurisdictional Determination form is available at: www.poa.usace.army.mil/Missions/Regulatory/JurisdictionalDeterminations.aspx under the above file number. Please contact us if you decide to alter the method, scope, or location of your proposed activity. This approved jurisdictional determination is valid for a period of five (5) years from the date of this letter, unless new information supporting a revision is provided to us before the expiration date. Enclosed is a Notification of Administrative Appeal Options and Process and Request for Appeal form regarding this approved jurisdictional determination (see section labeled "Approved Jurisdictional Determination"). 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 defines wetlands as those areas that are inundated or saturated by surface or groundwater at a frequency and duration -2 - 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.0 403). 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. Nothing in this letter excuses you from compliance with other Federal, State, or local statutes, ordinances, or regulations. Please contact me via email at Amanda.L.Whittier@usace.army.mil, by mail at the address above, by phone at (907) 753-5582, or toll free from within Alaska at (800) 478- 2712, if you have questions.
