The tank has already been set the contractor is ready to start on the fields. A percolation test was performed revealing favorable soils conditions. The fields are located near steep a steep slope. We believe the steep slope provisions of the code apply to this system where the field is within 20 -feet of a steep slope greater than 25% including: ® Trenches shall not exceed sixty inches in width. ® The steep slope is protected from erosion/retained by large rock. The rock extends from the top of steep slope to the toe of the steep slope shown on the drawings. We believe this meets the intent of the code. • The distribution pipe invert shall be a minimum of thirty-six inches below the top of the natural organic surface, measured on the downhill side of the trench. • The slope ranges up to approximately 40% below the field which is below the maximum 46%. The rock slope protection has vertical faces due to the nature of large rocks, however it is assumed that the slope of the soil behind the rocks would approximate the average slope of the rock surface. ® 25% and 46% slope lines have been added to the profile drawing to show a possible path which effluent may daylight. In these relatively free draining soils, we believe the 46% slope line would be a conservative approximation of where effluent could daylight. The 46% slope line does not daylight. The repair must be performed by a moa certified installer in accordance with MOA requirements. Repair of the proposed system will not negatively impact adjacent lots. Upon completion of the installation, a record drawing will be submitted showing the location of the new tank, leach field, well, and other applicable features.

We are requesting an expedited review of this application. Our review of available documentation and field investigation show that this project will not adversely impact any nearby Wells, Wastewater disposal systems, replacement disposal sites, or drainage flowing onto and off of the subject property. As shown on the plan, the tank will be greater than 10' from the house foundation. The tank will be of MOA approved construction. The tank shall be covered with a minimum of 2" moa approved insulation and 3' of cover or a minimum of 4' of cover without insulation. The home is apparently a 5 -bedroom house. We are requesting that the septic system be approved for 5 bedrooms. The tank will be 1500 gallons minimum. The leachfield was designed based on a percolation rate of 5.6 gallons per minute. An application rate of 0.8 gpd/sgft was used in design. Based on the perc rate being less than 6 minutes per inch, we believe a 1 gpd/sqft application rate is justified when considering the size of the field. A 5 -bedroom reserve site is shown. Additional soils exploration and a slope waiver may be required. The repair must be performed by a moa certified installer in accordance with MOA requirements. Repair of the proposed system will not negatively impact adjacent lots. Upon completion of the installation, a record drawing will be submitted showing the location of the new tank, leach field, well, and other applicable features.

This is a 2.5 acre parcel which is bordered on all sides by developed lots. The lots to the north, west and south are immediately adjacent to the subject lot. The lots to the east are separated by 30' municipal right away for Trails End Road. The subject lot is undeveloped and the septic system is design for a 4 bedroom home. WELL: The lot immediately to the south has an approved well and septic system. The well has been drilled but the septic system has not been installed. The location of the proposed well on the subject property impacts the property to the south. The location of the proposed well has been established to provide a minimum impact to the adjacent lot by overlapping the protective well radius with the well on the lot to the south. No other properties are impacted by the proposed well location. SEPTIC SYSTEMS: The lots on all sides have existing septic systems. These systems does not effect the proposed well or septic systems on the subject lot, nor does the proposed septic system on this lot impact the replacement area of septic systems on any surrounding lots. DRAINAGE: The drainage in this area is generally from east'to west. This lot has a gentle slope from the Trails End right of way westward for about 80' where it begins to slope steeply downward to the west. There is also a steep bank on the north side of the property, see sheet 4~/6 of the attached drawings. The proposed septic system has been placed in this gently sloping area adjacent to Trails End right of way and is placed greater than 50' from the shoulder of the steep bank. There is a deep ravine near the north property line. This ravine starts at the Trails End right of way. No running water has been noted in the ravine. The septic system has been located greater than 100 feet from the bottom o the ravine. There are no streams or other drainage channels which would impact the location of the purposed septic system. All disturbed areas will receive top soil and seeding to prevent soil erosion. 274nar.rep Rermif No. ~ Municipality of Anchorage Depar[ment of Health and Human Services ENVIRONMENTAL SERVICES DIVISION P.O.
