SHAFER March 24, 1985 CIVIL ENGINEER 694-2979 Municipality of Anchorage Department of Health and Environmental Protection ATTENTION: Susan Oswalt 825 L Street Anchorage, Alaska 99501 Dear Susan, REFERENCE: Case S-8041: Chugach Hills Subdivision Concept Plan This letter confirms our earlier conversation reference your concern for a drainage plan to insure protection of sewer system from surface water and protection of the creek from potential degradation. It is our opinion that a surface drainage plan is not required in that the septic systems to be located on Lot lA: and Lot 3 will be protected from surface run off through the construction of drive ways and building sites. A septic system currently exists on Lot 2A and is not subjected to surface run off. Surface water from Block 1 of this proposed subdivision is collected in the ditch on the upper side of Highland Drive and is discharged through well established, existing drainage patterns which do not affect this subdivision. Surface drainage for the lower lots in Block 2 Viii'be discharged below the proposed on-site waste water disposal systems into soils which are highly saturated and are covered with a thick musReg vegetative growth. This area will act as a large sponge and it is not anticipated that any surface runoff from the housing development will ever reach the river. If we may be of further service, please contact us.

Per your request, an adequacy test was performed on the existing on-site waste water disposal system on the proposed Lot 2; Block 1; of the referenced Subdivision. The septic tank supporting the residence on this lot has a capacity of 1000 gallons. The absorption area consisting of a seepage pit was tested for percolation and found to have a total percolation of approximately 950 gallons of water in a 24 hour period. It can be concluded that this on-site waste water disposal system is currently functioning adequately to support a three bedroom residence. However, the system cannot be guaranteed against subsequent failure. Examination of the existing well on this lot revealed that-.~ii'~-w~:~i~approximately 28 feet deep and produces ~ery little wa~. Since this well does not meet the minimum'd~pt~-P~escribed by law for a ~rink~_~t~_~ce, f~-~-ther work-u~--~-h-'-~~ was not performed. There are no existing legal wells within the immediate vicinity of this subdivision, however, existing wells in this valley in other subdivisions are more than adequate to sustain consumptive needs of single family dwellings.

Pace, we support the proposed vacation of South Fork Road adjacent to Tract B, Cusato Subdivision. Mr. Pace is purchasing Tract C of CusatO Subdivision, across the river from Tract B, and will be developing it as a residential subdivision with access from the south, through Tract B, Southfork North Subdivision. We feel that no need exists for South Fork Road right-of-way, and that it should be vacated. Other access will be provided to Tract C, Cusato Subdivision, and an additional crossing of the South Fork of Eagle River 'is unnecessary. We intend to vacate that portion of South Fork Road adjacent to Tract C, Cusato Subdivision when we submit our preliminary plat next month. Please call me if you wish to discuss this further.
