Civil/Structural Engineering and Construction 4661 Natrona Ave. Anchorage, Alaska 99516 Phone 345-3377 Fax 345-1391 July 17, 2019 Municipality of Anchorage On -Site Water & Wastewater Program 4700 Elmore Road Anchorage, AK 99507 RE: NEW SEPTIC TANK PERMIT & CONDITIONAL COSA LEGAL: PARADISE VALLEY BLOCK 6, LOT 8 Per discussions with MOA On -Site staff, we are requesting a conditional COSA with the permitted septic tank upgrade and well head improvements. The property has been vacant for an extended period of time and the buyer is obtaining a construction loan to address these issues after this short -sale purchase is completed. Attached is the associated lender letter. A new as -built survey with the inspection report will be provided after septic tank installation. Work will be completed within 30 days of the closing and all anticipated engineering / MOA fees will be paid prior to closing. The existing crib is adequate for 4 bedrooms and was tested for such,:, based on the soil ratings and square footage of the crib. It is assumed that the extended vacancy, dormancy of the property has contributed to the higher nitrate levels and once Linder normal daily use, those levels may drop. It is also anticipated that the replacement of the aged tank and wellhead improvements (casing extension & new seal) will also improve nitrate levels. In the event that the nitrate levels do not improve, the buyer is aware that other mitigating steps may need to be made such as pressure grouting the annular seal and replacing the aged galvanized pipe. The proposed septic upgrade and other improvements with the issuance of a Conditional COSA will not impact any of the neighboring properties or pose a public health risk. Please contact Brent M. Western or me if you have' any questions. Sincerely, WW4&--_ Michael N. Anderson, P.E. Support Services Brent M.
