The results of this test are attached for your review. The owner has requested we proceed forward to obtain a septic permit to upgrade the failed leachfield on the subject lot. Due to the fact that this is the only location for the absorption field, this upgrade design will constructed per the previously permitted design SW930424. The existing sewer rock, sand filter, and any contaminated soil will be excavated and disposed off-site per code. The general slope of this lot is from east to west at a grade of approximately 0-5 %. With the exception of one lot across the street, the property and adjacent lots are served by public water. There is no surface water within 100' of the proposed system and there are no known curtain drains within 50'. We do not expect there to be any adverse effect on adjacent lots by the development of this system. If you have any questions, please contact me at 868-3792/FAX 868-3793.

Box 196650 Anchorage, AK 99501 Reference: Lot 32 Block 2 Williamson #2, Job No. 93393 Ladies and/or Gentlemen: Ill June of this year, we were asked to evaluate the failed septic system on the referenced property. We deterndned that the existing seepage pit and draimqeld, which was added iii 1981, have ceased to perform their designed functions. We performed a soils analysis on all adjacent site on the west side of the property and north of the existing pit. We found soils able to receive septic tank effluent at a depth of 2.1 to 5.2 feet below die surface. These soils are a coarse sandy gravel (GP). We have designed a draiiffield adequate in size to accommodate a four bedroom resideRce. We also determined the septic taak has failed and is iii need of replacement. We are mcorporatiRg a new 1,250 gallon septic tank into tlfis design. As required by AO-90-48 (S-l), Section 15.65.030.D.4. we are submitting a narrative description of probable impacts to adjacent properties. In order to accommodate die draiiffield, we would be encroaching on the 100' radius required for the private well ou Lot 7, Block 3, Williamson #2. This well is the only private well iii the subdivision. The remaining lots m die subdivision are selwed by a community well. We have made arrangements to have this well abandoned and to connect the Leach family (owners iii residence) of Lot 7, Block 3, Williamson #2 to this community system and properly abandon the private well. Adjoining lots iii the subdivision are also served by on-site wastewater systems. The upgrade of the e.-dstmg system of the referenced lot should have little if any impact on adjoining systems. Designation of a reserved space is not required with au upgrade. The existing seepage pit and dmiidield, which have failed, will be left ill place and the septic tank effiuem diverted to the new drailffield. These systems should recover and be available as reserve fields if unused. Mmficipality of Anchorage October 6, 1993, Page 2 d. Drainage of the site is generally to the north and west at approximately 2% The overall drainage of the general ama is in the stone direction at higher slopes, approximately 5%.

Box 196650 Anchorage, AK 99519-6650 Subject: Separation Waiver, L32, B2, Willimnson #2, CAE Job No. 93393 Application is hereby made for the grmiting of a separation distance waiver according to Anchorage Municipal Code, Chapter 15.65.140. 1. Description of separation distances for which waiver is requested. A separation distance waiver of 84..0' from the proposed on-site draimqeld for L32, B2 Williamson #2 to a private well located in rile NE portion of LT, B3, Williamson #2. The waiver is requested as the only reasonable way to serve the existing unit and stay 10' away from the existing failed system. RECEIVED 2. Information on soils and topography. The ground around the proposed site gently slopes upward to the west at about 1% gradient toward the neighboring private well. To the east of the house it slopes upw,'u:d at a 5% slope. The ground to the nm'th proceeds level for about 50', then slopes dowuward at a 3% slope. No bedrock was found in either of the recent or previous test holes dug ou site. The soils data collected fi'om test hole information extending downward consists of about 1 ,l' layer of lomn underlain by a 3.5' clemz gravelly sand (GW) layer. Beneath tlds frmn 7.6' to 9.,6' lies a silty sandy gravel (GM/SM) layer. Beneath this lies 1.4 of sandy silt (SM) and the final 3' to the bottmn of the 14' T.H. was found to be gravelly silt (GM) material. (See enclosed soil log.) 3. Well by well log information. There is no fldly recorded well log for the well on Lot 7, Block 3, Williamson #2. There is record of its extension (included) from 200 to 240 feet, with a cased depfl~ of 238'. This will place thc bottom of rile proposed adsorption field 232' from rile cased depth of the well in question. In an atteznpt to provide geologic izfformation on the area, rile well logs from three surrounding wells have been provided. A map is presented identifying the locations of the wells.

Name of Firm Arcterra Consultin Engineer's Printed Name Kenneth Duffus Phone (907)-696-x6111 Date Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. 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 inland use, local soil characteristics, groundwater levels that may fluctuate during the year i s and the water usage of the family being served by the system. 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 Al of the well and septic system. Therefore, ArcTerra can not give any estimate of how long a system will function satisfactory for current or future occupants or can ArcTerra guarantee that no unseen ■� encroachments, deficiencies or discrepancies exist. i'n COSA Checklist June 2022 V_.
