CONSULTANTS & GENERAL CONTRACTORS - r February 6, 2013 S4 Group 124 E 7th Avenue Anchorage, Alaska 99501 Attention: Tom Dreyer office 907 306-8104 Ref: Septic Reserve Map and Test Hole Information for Proposed Sky Manor S/D), (A Subdivision of Tundra Jewel Ranch S/D; Lot 20) Mr. Dreyer: Per the request of our client, John Thomson with C&T Construction, we performed numerous test holes on the referenced property for the purpose of identifying suitable septic system sites, as require to subdivide the property. It is our understanding that our client would like to develop the property into 7 lots with a duplex to be built on each property. The duplexes shall be limited to 6 bedrooms total (3 bedroom per unit maximum). Per AMC 15.65.180, septic reserve areas or platted drainfield sites must be provided in order to subdivide the property. Attached is a septic reserve site plan which shows the test hole locations, the well drilled on the property, the proposed water main/service line locations, the proposed duplex locations, septic reserve areas, and platted drainfield sites. Based upon the soil percolation rates on lots 1, 2, 3, 4, and 5, septic reserve areas of 10,000 sq.ft are required for each lot. Test hole #13 (proposed Lot 1) and test hole #1 (proposed Lot 2) had percolation rates of 3.33 minutes/inch. Test holes #3, #4, #5, #6, #7, and #8 for proposed lots 3, 4, and 5 had percolation rates of <1 minutes/inch. Lots 3, 4, and 5 will require 2 foot sand filters with bed type or shallow trench type drainfields. Due to the limited available area on the proposed Lots 6 and 7, platted drainfield sites will be required for each lot. Test holes #9, #10, #11, and #12, for proposed Lots 6 and 7, had percolation rates of<1 minutes/inch. Lots 6 and 7 will require 2 foot sand filters with bed type drainfields. On the site plan drawing we have provided the design criteria for the platted drainfield sites for Lots 6 and 7. SURFACE WATERS: There are no surface waters within 100 feet of the septic reserve areas or proposed plated drainfield sites. TOPOGRAPHY: The average topography for the tract of land is a 5 percent slope running approximately south to north. Bed type drainfields with sand filters are anticipated for a majority of the proposed lots. There are no concerns in regards to topography with these type of installations. 3701 E.

Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Ref: Waiver Request for Proposed Lot 7, Skyview Manor Subdivision (S11977-1) Ms. Wockenfuss: Per your direction, we are requesting a waiver to the 40,000 sq.ft. minimum lot size for a septic system for the proposed Lot 7, Skyview Manor S/D. This subdivision of Lot 20; Tundra Jewel Ranch S/D will subdivide the property into seven (7) separate lots. Lots 1 through 6 meet the 40,000 sq.ft. requirement, but Lot 7 is just shy of the minimum square footage requirement (38,706 sq.ft.). The following is justification for this waiver: • The septic reserve area for Lot 7 will be required to be shown as platted drainfield sites on the plat as shown on our septic reserve map. The platted drainfield sites meet all MOA wastewater requirements and we have shown that there is adequate space for these three (3) drainfield sites. The well for the subdivision is already drilled and has been surveyed. The septic reserve map shows the accurate location of this well and the 200 foot well radius. In short, there is adequate area for the proposed septic system for proposed Lot 7. Based upon this justification, we request this waiver be granted. If you have any questions, please contact us at 337-6179. Thank you for your assistance. Sincerely, 'y L . - • ess, P.E., M.S.

Garness Engineering Group,Ltd. 3701 E.Tudor Road,Ste. 101 Anchorage,AK 99507 Re: Sky Manor Wellhouse,Tundra Jewell Ranch Subdivision,Lot 20 New Community Groundwater System- Construction Approval Dear Mr. Garness: On June 11,2013 this office received your request for Construction Approval for the above referenced project. The intent of this letter is to issue Construction Approval for the improvements detailed in your submittal and outlined below. Project Description This project proposes to develop an untreated groundwater drinking water system to serve seven future duplex housing units in the Tundra Jewell Ranch Subdivision in Chugiak,Alaska.The well to supply this system was completed on May 14, 2007.The 6" steel cased well was drilled to a depth of 272'and was grouted with bentonite chips to 20'below ground surface. The well provides a sustained yield of 20 GPM (gallons per minute) and accesses a presumed semi-confined aquifer,penetrating intermittent lenses of tight slits, sands,gravels,and mixes thereof. Sampling of the raw water showed it to be free of regulated primary contaminants. Water will be supplied to the system by a Grundfos well pump,model 25S20-11.Water storage for the system is provided by two 1,000 gallon tanks plumbed in parallel. From the storage tanks,distribution system pressure is provided by two Grundfos pumps,model CRE5-9. At the entry point to the distribution system a 2"Badger master meter,model M120 LL,will be installed.The distribution main for this new system will consist of approximately 750 linear feet of 3"HDPE (high density polyethylene)pipe and service connections will be through 1" type"K"copper lines. Also included in the project is the installation of valves, cathodic protection,and other related appurtenances. Capacity Development The owner of this system,John Thomson,provided financial and managerial information. From the information provided, this system will cost approximately$550 per month to operate;this includes utilities, engineering,and sampling costs.The total 30 year replacement cost of critical system components is estimated to be approximately$24,000.This cost will be shared across the 14 housing units. Amortizing this cost back to present value at a 2% discount rate shows that a fee of approximately$50.00/month/unit should adequately fund this water system.This fee is comparable with other utilities in the area;however this estimate does not include any wastewater treatment/disposal costs.Wastewater treatment/disposal systems will be owned, operated,and maintained by the individual homeowners. Construction Approval The submitted engineering plans and supporting information have been reviewed and are approved in accordance with Alaska Drinking Water Regulations (18 AAC 80). The enclosed Construction and Operation Certificates,with the Approval to Construct section completed, constitutes written approval.Deviations from approved plans which affect capacity, flow,pressure,operation,compliance, materials of major system 130906_Sky Manor_218807_CA.docx Page 1 of 3 Mr.Jeff Garness,P.E. September 6,2013 components (particularly any components which do not meet NSF Standard 61),must be approved by DEC prior to their construction or implementation. For information on this system's required future water quality monitoring please contact Leticia Tadina (269- 7517), the Drinking Water Environmental Program Specialist for your area. Interim Approval to Operate As part of your submittal requesting Interim Approval to Operate,please provide written verification of the following: 1. Construction of the water system has been completed under the direction of a professional engineer licensed to practice in the State of Alaska and in accordance with the engineering plans and specifications; 2.

Water distribution lines,wellhouse plumbing,and the well have been flushed,disinfected,and sampled for total coliform in accordance with current AWWA Standards C651,C653,and C654 respectively. Provide the location in the system where each sample was taken (plan or station numbers),the time and date of each sample,and the results for each sample. 4. Certification Form showing that a Priority Measures Plan has been completed. For more information,please contact Tyler Fanning,269-8924 and visit the Drinking Water Security webpage at http://dec.alaska.gov/eh/dw/security/security ret s.html Final Approval to Operate Final Approval to Operate should be requested within 180 days of receiving Interim Approval to Operate. As part of your submittal requesting Final Approval to Operate,please provide the following: 1. Record Drawings,stamped and signed by an engineer licensed in the state of Alaska,confirming that the system meets the requirements of 18 AAC 80. `Record Drawings"refers to the original plans prepared for construction and department approval,revised to reflect how the system was constructed or installed. 2. Verification that the water system is being operated by a person appropriately certified for this system in accordance with 18 AAC 74,Water&Wastewater Certification&Training. For further questions please contact Ken Smith with the Operator Certification and Training Program at 465- 5136. 3. A Water System Inventory Form completed by an engineer that was involved in the system design or construction oversight.This form will be used as a baseline for future sanitary surveys, and can be found on the Drinking Water Program website: http://dec.alask-t.goviehidwipublicationsi forms.html Construction Approval Expiration If the applicant fails to construct,install,renovate, or improve the public water system within two years after the department issues an Approval to Construct under Drinking Water Regulations 18 AAC 80.210(c), the approval is void and the plans and information required under 18 AAC 80.210(a) must be resubmitted for the department review and approval. If during the two-year period the site conditions,plans and information,and requirements in this chapter do not change,and if the applicant pays the fee required by 18 AAC 80.1910, the department will grant the applicant an extension. Construction Approval Limitations Any changes,constructed or natural,which affects the conditions to which these approval was granted will void these approval. Issuance of these approvals does not imply the granting of additional authorizations,nor obligate any federal, state,or local regulatory body to grant required authorizations.This is not an approval of omissions or oversights by this office or noncompliance with any applicable regulation.The Department's approval to operate does not guarantee correctness of the functional design or waiver the owner's responsibility for continued compliance with State regulations. 130906_Sky Manor_218807_CA.docx Page 2 of 3 Mr.Jeff Garness,P.E.
