The attached site plan identifies the location of the home as well as the existing well, septic location and alternate site. No conflicts exist between this proposed system and any wells, whether on this lot or adjacent lots. Drainage arrows are shown on the site plan showing the grade and direction of flow. The drainage pattern in general will not be changed by the construction. The test holes placed on the lot indicate silty sand with gravel.No bedrock was found down to 13', although seasonal high groundwater levels were measured at 5'. The percolation rate was determined to be under 1 min/in in one of the test holes. Test holes on the adjacent lots indicate typical percolation rates of between 6-15 min/in. We will perform additional perk tests to verify the perk rate in the area where we propose the septic system. An application rate of 0.8 gpd/sf was used in the design of the absorption system. We are proposing to place a new 1250-gallon STEP tank with two shallow absorption trenches 5' wide x 57' long x 0.5' effective depth. The elevation of the distribution line will be 0.5' below the surface for a total depth of 1'. Soil will be mounded 2' above the trench. A minimum of 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. The ground surface on the lot slopes moderately in the front, but then levels out into a wide field in the back of the lot. There are no slopes greater than 25%anywhere on the lot. It is in that flatter area that the new septic system is located. The new trench will be constructed parallel to the slope as much as possible. It will be a minimum of 100' from all wells and surface water,and more than 5' away from the septic tank. The alternate site is located more than 10' away. If the system is constructed as designed, it will have no adverse impact: • On the wells in the area or those to be constructed in the future. • On existing septic systems in the area or those to be constructed in the future. • On reserve space, either surface or subsurface, on any lots located in the area. • On drainage patterns in the area. The current drainage pattern will be maintained.

BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 (FAX) September 29, 2017 Municipality of Anchorage Building Safety Division On Site Water and Wastewater Program 4700 Elmore Street Anchorage, AK 99507 Attention: Debbie Wockenfuss Subject: Glacier Vue Subdivision, S-12357 Septic System Feasibility Dear Debbie: The owner of BLM Lot 21, Section 4, T15N, R1W S.M. intends to subdivide the tract into two lots. The two lots are fronted by Glacier Vista Road at its intersection with Oberg Road in the Chugiak area. The westerly half of the lot is currently under development and a well and septic system has recently been constructed. The permits were issued on the entire lot, but construction was limited to the confines of the westerly half. The new subdivision will be known as Glacier Vue Subdivision, Lots 21A and 21 B. The ground surface of the lots slopes from the north to the south at varying grades approximating 5%. Flatter areas were located on both of the proposed lots for home sites and septic systems. Lot sizes are in excess of 40,000 square feet in surface area and sufficient space is available for placement of wells and septic systems to meet the 100' setback requirement. Test holes were placed on the proposed lots on April 5 of this year. Soil assessment and percolation testing was completed on that day. Water monitoring has been ongoing with readings to be taken through October 15. 2017. The purpose of the test holes was to assess the underlying soil conditions and to determine whether septic systems could be placed on the lots to serve single-family homes. The test holes were placed to various depths ranging from 11' to 15' with no bedrock or impermeable lenses of material encountered. The locations of the test holes were determined in the field for use in the future for developing septic systems. Percolation benches were constructed at various depths in the holes, but primarily 3' to 6' below the original ground surface. A percolation cavity was prepared to determine the absorptive characteristics of the soils encountered. The cavity was presoaked in accordance with Municipal requirements and a percolation test performed. The results of the tests are included in the attached documentation. Well graded gravel sand (SM/SW) with varying degrees of gravel and silt was encountered to Glacier Vue Subdivision September 29, 2017 Page 2 the bottom of each test hole. The percolation rate in this material ranged from less than 1 minute per inch on Lot 21A to 30 minutes per inch on Lot 21B. Soils encountered on Lot 21A appeared to be more than 50% sand. A sand liner is not anticipated to be required on this lot. A 10.000 square foot septic system reserve area is shown on Lot 21A. Lot 21B has an approved septic system on the lot. All work was completed under the direction of technicians and engineers at Anderson Engineering. The results of the percolation tests and test hole logs are included. Groundwater was found in Test Hole 1 , but was initially absent in the remaining holes. The water level has been monitored through the high water period of May 15 through September and levels recorded. The water levels were noted at 3.5' below the surface in test holes 3 & 4 on June 2, 2017, and the system for Lot 21B was designed based on that information. Water levels were at 5.5' for test holes 1 & 2 on September 29, 2017. Test Hole Logs and a Location Map are included which illustrate soils encountered, percolation rates and their respective location on the individual lots.

BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 (FAX) October 3, 2017 Municipality of Anchorage Building Safety Division On Site Water and Wastewater Program 4700 Elmore Street Anchorage, AK 99507 Attention: Debbie Wockenfuss Subject: Proposed Glacier Vue Subdivision (S-12357) Water Availability Study Dear Debbie: We have collected information on several wells in the area of the proposed Glacier Vue Subdivision to estimate the possible depths and production rates of wells to be constructed in the future on Lots 21A and 21B. A well was recently constructed on Lot 21B which was the focal point of our study. In addition a well is currently in place on Lot 21A, but no information is available as to the depth or production of the well. It is assumed to be drilled to the same aquifer level as the well on Lot 21B as it is less than 85' from the well. The well on Lot 21B was constructed without the presence of bedrock below the surface. The well was cased to the bottom of the well. The depth of the well is 182' with a production rate of 7 gallons per minute. It is obvious from our study that the well currently on proposed Lot 21A is sufficient to support a four bedroom home and can be expected to produce between 3 and 4 gallons per minute. The well will not affect the operation or output of the existing wells in the area. vabiet.Vi 41 Sincerely,' ,,,�. G;.' x • : 49 s .� 0P=3: Benjamin Schiller, P.E. * .

ENGINEER’S COMMENTS G. 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 8/30/2024 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 & 8/30/24 I�t rl O en rn rn n n m m m m �X O ro rn - LLJ V z Q LL', J z 0 LU o U N Q ZmLu s i N � LU V � v w N � Q t— bjO LLJ O a) E > 0 o N JE bD E i aj aj — i Q N E bA c» 00 Lf) 4- X E m s � NfB N ate.+ N ai ca u ?� b,0 X v O_ a cn -0 vii Q N a� 3 O m " 4% D f6 : O N N v - N O 4- +� N U W + Z U 4 a 0 ateJ N C O O ate.+ U •ate— U U N N s •� ., ^C C� rM-I d r -4 � >O Q Q N O J O c O C 0 U v Q� w U Q u Q O O t1A o d W •N s ti() O N LJ 0 a� O 0 N m w 4 aw+ do 4- 4- O a� O co 0 NV � '+_� a� s 4- }' -'O s EO N 4�0>' v O N }' f° V U > m 0 O `� cn v a N E M.
