APPROVING THE VACATION OF THE NORTHERN 25 FEET OF A 50 -FOOT SCREENING EASEMENT LOCATED ALONG THE SOUTHERN PROPERTY BOUNDARY OF LOT 10, BLOCK 2, POTTER HEIGHTS SUBDIVISION, AS SHOWN ON PLAT 81-224. (CASE S12508) WHEREAS, a petition has been received from John DeCarlo (owner), to vacate the northern 25 feet of a 50 -foot screening easement located along the southern property boundary of Lot 10, Block 2, Potter Heights Subdivision, as shown on plat 81-224; and, WHEREAS, a public hearing was held on October 2, 2019. NOW, THEREFORE, BE IT RESOLVED by the Platting Board that: 1. The Platting Board makes the following findings of fact: a. The easement is surplus to current and future needs. b. The standards set back in 1981, when this easement was originally established, did not require screening of this nature because there are no conflicting uses in the area. C. The reduction to 25 feet will remove the slight encroachment of the existing house. d. It will reduce fire hazard by giving the ability to clear trees farther from the structure than is presently allowed. 2. The Platting Board APPROVES the vacation of the northern 25 feet of a 50 -foot screening easement located along the southern property boundary of Lot 10, Block 2, Potter Heights Subdivision. PASSED AND APPROVED by the Anchorage Platting Board this 9th day of October, 2019 subject to the following conditions: 1. The remaining 25 feet of the screening easement shall abut Potter Heights Drive. I II III�IIIIIIIIIIII 2of3 eRecorded Document 2019-037878-0 Platting Board Resolution No. 2019-010 Page 2 2.

Health '~Y~,f AnChora,~,, August 7, 1996 Department of Health and Human Services On-Site Services Division 825 "L" Street, Suite 502 Anchorage, Ak 99501 SUBJECT: Lot 10, Block 2 Potter Heights Subdivision Well and Septic System Permit Application Dear Dan: Thank you for your review comments on the above referenced system. We have redesigned the plans for your review. This is a new subdivision and this will be one of the first houses and there are no improvements within 200 feet to get measurements from. Proposed System Design The proposed system has been designed as a shallow trench system. This system was chosen due to the high ground water in the area. The initial soils investigation occurred on 9/13/96. Ground water was encountered at approximately 4.5 feet and 6 feet at the time of the investigation. A subsequent site visit on 7/08/96 revealed no ground water present. The material encountered in the test holes ranged from a poorly graded sand to a poorly graded gravel. Percolation rates exceeded the minimum of 1 inch per minute. Percolation test results are attached for your review. A two foot sand layer will be installed under the drain field where native sand is not present in order to provide the necessary filtration layer. The system was designed for three bedrooms, giving a design flow of 450 gallons per day. An application rate of 1.2 gpd/ft2 was used in the design. The area required was calculated to be 375 ft2. Yielding a two 5 foot wide by 37.5 long drainfield. The proposed septic tank is 1250 gallons and is to have two feet minimum cover with four inches of expanded or extruded polystyrene insulation above it. The connecting piping is also shallow and will require 4 inches of board insulation. The existing ground has a slope of 14% to 16%. Over 40 Years Serving Alaska 911 West Eighth Avenue · Anchorage, Alaska 99501-3497 o (907) 279-0543/FAX (907) 276-7679 TRYCK NYMAN HAYES, INC. On-Site Services August 7th, 1996 Page 2 Lot information: The subject lot is approximately 1 acre; the lot is constrained on the South by a Potter Heights Drive and a 50 foot screening easement and slopes away to the NoRhWest at approximately a 15 % slope. The proposed house is to be located in the middle of the lot on the side slope. The proposed septic system has been set parallel to the slope and inset slightly. In any event, the width of the proposed system and the relative fast percolation rates make it unlikely that there would be any effluent seeping out the toe of the slope. The designated replacement system is located 10' to the North-West and downhill of the primary system. Possible Points of Contamination: It is unlikely that there would be any contamination of the future wells on the surrounding lots. The lot immediately to the north is undeveloped at this time. Any lots to the east are separated by Potters circle and in any event are up-slope. The lots to the North-West, while down slope, are more then 100 feet from the proposed septic system and are also undeveloped. The proposed well for this lot is located along the slope and slightly above the proposed septic systems. I do not foresee any problems with contamination of the proposed well. If you have any questions or concerns, please do not hesitate to call. Sincerely,  INC: Project Engineer Permit, No. P.O.

ANDERSON, PE Date 6/19/2019 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 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 Mrs and Anderson Construction & Engineering. 6.
