Civil&Environmental Engineering May 25, 2017 Onsite Reviewer Municipality of Anchorage On-site Water&Wastewater Program 4700 Elmore Road Anchorage,AK 99519-6650 Reference: Sand Lake#2, Block 6, Lot 5 Permit OSP171018 and Waiver OSV171009 Change Order 1: New Engineer and Septic Design The owner of the subject property (5-bedroom duplex) has decided to retain Crewdson Engineering LLC (CE)to complete the project. Change Order 1 is CE's proposed design. The existing septic system needs to be upgraded. The following is a list of the issues that need correcting and the proposed upgrades. 1. The septic tank and drainfield are undersized by one bedroom. a. Design proposes to i. Decommission the existing septic tank ii. Install a new 1500-gallon septic tank, and iii. Increase the size of the existing drainfield to accommodate five bedrooms. 2. The existing drainfield pipes need to be thoroughly cleaned and the drainrock needs to be remediated. a. Design proposes to i. Hydrojet clean the drainfield distribution pipes ii. Install a Bio-Microbics RetroFAST 0.375 treatment system to remediate the drainrock. Please revise waiver to be for the following separation distances only, which are slightly less than what's shown on the drawing to allow for small adjustments to the design during construction. 1. Subject property well to a. Proposed septic tank: 78 feet b. Proposed drainfield: 92 feet i. JUSTIFICATION: 1. A recent well water analysis for a coming COSA shows Nitrates (Non- Detect)and Coliform Bacteria (negative) are both good. 2. Surface Pollution:The property is relatively flat and is likely to cause any overflowing sewage to have substantial pooling on the ground surface PO Box 671389 • 18368 Amonson Road • Chugiak, Alaska 99567 Page 2 of 2 May 25, 2017 Sand Lake#2, Block 6, Lot 5 Permit O5P171018 and Waiver OSV171009 Change Order 1 before migrating to the well. The well is on the opposite side of the house from the septic tank and drainfield,which are both located near the main entrance to the house and the garage. As such, any overflowing sewage is likely to be seen and taken care of long before it has an opportunity to flow around the house to the well. 3. Sub-surface Pollution:The well depth is 407 feet with a static water level of 143 feet, which means it's pressurized to 113 psi [(407 ft. — 143 ft.) x 0.43 psi/ft.= 113 psi]. The aquifer's high pressure at this location clearly indicates it's very confined and as such would be near impossible to pollute from the subject property above. 2. Property line to proposed drainfield: 2.0 feet a. JUSTIFICATION: i. The undersized lot doesn't have any available room to locate the drainfield away from the property line. ii. The drainfield is not likely to have any adverse effects to the adjacent right-of- way to the south. The edge of street pavement is currently greater than 10 feet from the proposed drainfield. iii. The drainfield is not likely to have any adverse effects to the adjacent private property to the west. The septic tank for this lot is approximately 9 feet from the proposed drainfield. 3. Foundation to proposed drainfield: 6.0 feet a. JUSTIFICATION: i. The undersized lot doesn't have any available room to locate the drainfield away from the foundation. ii. The drainfield is in fast percolating soils that are not likely to allow effluent to migrate laterally to the foundation. A very small portion of the drainfield is located less than 10 feet from the foundation and as such is not likely to have any adverse effects on the foundation.

Name of Firm: Gamess Engineering Group. Ltd (GEG) Phone: 907-337-6179 Address: 3701 East Tudor Road, Suite 101- Anchorage, Alaska 99507 Engineer's Printed Name: Jeffrey A. Garness Date: --=1-1 3o 2 -Z In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the systems on the dates of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational fife of all wells and septic systems depend upon a variety of variables, including but not limited to, soil conditions, groundwater levels (that may fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the systems. These conditions can vary, andl' are outside the control of GEG. Satisfactory test results do not guarantee future performance of the system/s; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation. Reliance upon the information provided in this report by any other person or party (including subsequent property purchasers) is not authorized, nor will it confer any legal right whatsoever. 6. !TIGNATURE System #1 Approved for s� bedrooms System #2 Approved for Disapproved Conditional approval for bedrooms bedrooms, with the foil CES 0 i By- �/ Original Certificate Date: The Municipality of Anchorage Development Services Division (DSD) issues Certificates of Onsite Systems Approval (COSA) based only upon the representations given In paragraph 5 by an independent professional civil engineer registered In the State of Alaska.
