The approved separation distance is 0.0 feet. See the engineers waiver request for the approved design. This waiver approval applies to the proposed absorption field only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. ❑ The affected adjacent property owner(s) have been given a 7 day notice regarding this waiver. ❑ Notarized letter(s) of nonobjection have been received from the owner(s) of the affected adjacent property. ® Adjacent properties are not affected by this waiver. ...............................................................................

The absorption pit abandoned more than 20 years ago lies in the alignment of the new trench. We are confident this pit is now dry. All remnants of the old pit will be removed and replaced with coarse sand prior to placement of the new trench. In addition the new trench will be constructed 10' from the existing trench on the lot. The soil on the lot percolates at rates less than 5 minutes per inch. Little migration of the septic effluent is expected. We therefore recommend the new trench be placed atop the abandoned absorption pit on the lot and 10' from the existing trench on the lot. Sincerely, Michael E. Anderson, P.E. OF 49th •'. MICHAEL E.

We are therefore requesting a permit be issued for the upgrade of the septic system to accommodate the home on the lot. The attached Site Plan and backup documentation identify the location and configuration of the existing and proposed septic system. The existing 1,250 Gallon Septic Tank will be abandoned in accordance with Municipal Code and replaced with a new 1,250 Gallon Septic Tank. The existing absorption trench will be left intact and tied to the new system with a flow diverter valve. Also identified on the plans are the locations of the existing well on this and adjacent lots and adjacent septic systems. No conflicts exist between the proposed septic system and the wells on this or adjacent lots. Protective radii are shown to the adjacent wells. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. The test hole previously placed on the lot indicated silty sand and sand (SM/SW). The percolation rate was determined to be less than 15 minutes per inch. We have designed the new trench with an application rate of .8 gallons per date per square foot. We are proposing to place a 47' long trench by 3' wide with an 8' effective depth. The total depth of the system will be 12' with the distribution line at 4' below the existing surface. A new test hole will be placed and a percolation test completed to verify the absorption characteristics of the underlying soil and verify the absence of groundwater and bedrock. If conditions are found to be different than anticipated a change order will be submitted with a new design for the trench. The homeowner wishes to maintain as much of the vegetation in the area as possible and is requesting only one mobilization of heavy equipment to the area. Lot 4, Block D, Knik Heights October 22, 2011 Page Two The ground surface on the lot slopes slightly to the southwest in the area of the absorption trench. The trench will be placed parallel to the contours of the ground as much as possible and in conformance with design criteria. A minimum of 100' will be maintained between all components of the septic system and the proposed well and from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: 1. The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

The following discrepancies worn noted: 1) No standpipe on septic tank. ( A 4" cast iron standpipe is required and should extend above ground level.) 2) The ground has settled around the seepage pit allowinv rain water and runoff to enter the pit. (rill needs to be brought into this area.) 3) The well casing_ is at ground level and a bolt is missing from the well seal. (The well casing should extend a minimum of 12" above the ground surface and the grade: should be sloped away from the well casing. The well seal should he watertight.) R water sample was obtained from the 112' well and the bacteriological water analysis is satisfactory. Enclosed is a diagram of the water system and the proposed well location as approved by this Department on October 20, 1970.

CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines, indicates that the on-site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm FIRST WATER CONSULTING Phone 907-350-9566 Engineer’s Printed Name CURTIS HUFFMAN, PE Date 11/08/2024 Comments: This investigation was completed in compliance with MOA guidelines, regulations, and best industry practices / methods. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 11/08/24 MUNICIPALITY OF ANCHORAGE DEVELOPMENT SERVICES DEPARTMENT] On -Site water and Wastewater Section —� www.muni.org/onsite Well Water Advisory Certificate of On -Site Systems Approval # OSC241470 Subdivision: Knik Heights, Block: D, Lot: 4 907-343-7904 Fax: 343-7997 This well's productivity was determined to be 0.6 gallons per minute.
