EKES was contracted by Mr.& Mrs. Schommer to perform a soil investigation for the proposed subdivision to determine the feasibility and suitability of the proposed new lot to support on-site wastewater disposal systems and private wells. OVERVIEW The subdivision consists of splitting the existing 2.5 acre parcel into 2 halves. Two test holes were excavated on the undeveloped half of the lot by the homeowner with a rubber tired backhoe with extend -a -hoe. These test holes were logged by Chris Wood of ERES in early May, 2007. Soils percolation tests were performed adjacent to these test holes, with water table monitoring conducted through June, 2007 SUMMARY OF FINDINGS The following represents a summary of our findings. The proposed lot subdivision lies on the upland bench west of Peter's Creek off of Sunset Boulevard south of Jayhwk St. The proposed subdivision has a sparse cover birch trees, with occasional cranberry and alder patches. A majority of the proposed new lot has already been cleared of trees The underlying soil encountered can be characterized by being brown slightly silty sand & gravel with some cobbles, underlain by brown and/or blue clay. UCS classification would consider this soil to be SW or GW. Clay, and/or gravelly clay is present beneath this soil layer. However, saturated SW and GW soil on top of this clay layer prevented us from determining the depth and extent of this underlying soil layer. The limiting design factor is the water table, rather than the impermeable layer. Satisfactory percolation results were obtained in both test holes. Shallow groundwater was found in both of the test holes, perched above the underlying impermeable layers. This groundwater was monitored during our observation period of May, 2007. No surface water was noted within the confines this proposed lot subdivision, nor within 100' of the proposed wastewater disposal area. The proposed subdivision's topography only exceeds 25% slope along a slope break running north south, and along the proposed lot line, and is clearly identified on our site plan. No septic system is proposed to be within 50' of the uphill break in topography. With the exception of the slope break, the remainder of the topography is gently sloping west, or flat, not exceeding approximately 5% slope. We believe the two proposed lots can safely support a primary and two replacement on-site wastewater disposal fields. Due to the nature and apparent limited extent of the free -draining soil deposit, the reserve sites on the new lot will need to utilize category III treatment systems. Lot Size exceeds 40,000 square feet (minimum lot size required for installation of an on-site wastewater disposal system) on both lots. ON-SITE WASTEWATER DISPOSAL RECOMMENDATIONS ERES has confirmed that suitable soils and area exist on both lots conforming to Anchorage Municipal Code Chapter 15.65, and can provide safe wastewater disposal systems that are protective of human health and the environment. We recommend that the leachfield sites be recorded on the plat, rather than be included in a "general area" of 10,000 square feet, as the location of the free -draining soil appears to be limited to the area where the test holes were excavated. Leachfields for the new lot would need to be of abed or shallow drainfield type with at least 2' of MOA approved sand for a filter layer, and to provide adequate clearance to the observed water table based on historic data, and at the time of installation. WATER SUPPLY Several well logs obtained in the general area of this subdivision and have been included for your review. Well production rates appear to vary. A well has already been drilled on this property, and it produces approximately 0.48 gallons per minute. Nearby wells produce anywhere from 0.5 gpm to 8 gpm. We do not believe that this new well will adversely impact the water availability on adjacent lots due to the sparse spacing of wells in the general vicinity, and the nature of the recharge of this aquifer. NITRATES EKES has found some Nitrate concentration information on the lots surrounding this subdivision. ERES does not believe the construction and use of an on-site septic system on the proposed lot subdivision will adversely affect the surrounding lots' potable water supplies. Available samples include levels of 0. 19, 1.87, and 6.22 mg/L. LIMITATIONS Test hole findings reflect local conditions at the test hole locations only, and are subject to natural variations and changes. Conditions during leachfield installation may be different from those found in the test holes, and must be designed around accordingly. ERES appreciates the opportunity to provide you with continuing services on this project, and is looking forward to working with you on future projects. Please contact us if you have any questions.

However after further review by the city attorney, it was determined that for BLM lots without dedicated ROW's, set backs are determined from the property line (road center line) rather than from the BLM easement. The efore, the vacation request was withdrawn.'�plvai$��C� %1'% elzz-O . -k • iD bE C.li21 CQ b� mtul Zoning: The lot is zoned RSA. Streets: In accordance with the Official Streets and Highway Plan and Chugiak-Eagle River Transportation Plan, the property is bordered on the south by a planned local road (Tarika) with a 60 foot ROW width. A 30 foot dedication is proposed. The property is also bordered on the east by an existing Class M collector that with a 70 foot ROW width. A 35 foot dedication is proposed. Setback Requirements: The southern property line that borders the planned Tarika roadway is considered the front yard with a 25 foot setback requirement. The closest structure to the southern property line is 68 feet. With the proposed property line after the 30 foot dedication, the front yard setback will be 38 feet -still meeting the 25 foot setback requirement. The eastern property line that borders Sunset Boulevard is considered the secondary front yard with a 12.5 foot setback requirement. The closest structure to the eastern property line is 58.2 feet. With the proposed property line after the 35 foot dedication, the secondary front yard setback will be 23.2 feet -still meeting the 12.5 foot setback requirement. All existing structures are currently and will continue to meet setback requirements. See attached municipality email message for clarification of front yard and secondary front yard designations. Acreage Requirements: R5A lots require a minimum of 43,560 square feet. The current lot acreage is 108,900 square feet. After dedication and subdivision each lot is planned to contain 44,250 square feet each. Lot Coverage: R5A allows a maximum of 30% lot coverage. After subdivision, existing structures will cover only approximately 7% of Lot 2. Lot 1 will be unimproved. Legal Access: Legal access to Lot 2 is via a public Class IB collector. Legal access to Lot 1 is via an existing 20 foot wide by 300 foot long driveway along a portion of the planned Tarika roadway and extending along a 20 foot wide by 25 foot long portion of the ROW adjacent to Lot 155A. Driveway is constructed on the 50 foot BLM portion of Lot 156 rather than the 30 foot ROW that borders Lot 149B. An municipality Access Agreement exists between Lot 150 and 156. See attached Access Agreement and ROW Permit. Johnson, Mary K. To: Weaver, Jerry T. Subject: S•10316 Petitioner has asked for clarification of our comments concerning the primary and secondary front yards. It Is appropriate to call the Tarda frontage the primary front yard requiring a 25 foot front yard setback, and the Sunset frontage the secondary front yard requiring a 12.5 foot setback. This would allow a vacation of 15 feet of the BLM easement for Sunset Boulevard and stili meet the setback requirement.
