Box 196650 Anchorage, Alaska 99519-6650 Subject: Upgrade Sewer Permit - Crestwood S/D, Lot 9 Gentlemen: On April 11, 1998, we excavated two testholes for the subject property. The results of these tests and water monitoring are attached. We propose to install a 5' wide shallow trench. There was no water observed during the testhole excavation or after monitoring. Due to the depth of the system additional fill will not be required. This lot slopes from south to north at approximately 5-10% which is away from the proposed house and any surrounding wells. There is sufficient area for the primary and reserve system within the radius of the testhole for the four bedroom single family residence. The existing field and tank will be abandoned in place. The proposed upgrade is in conjunction with a short plat being processed separately by the owner. There are no public or private wells within 100' of our proposed system location. There is neither surface water within 100' nor any known curtain drains within 50'. We do not expect that there will be any_ adverse effect on adjacent lots by the development of this system. : If you have any questions, please contact me at 696-6111/FAX 696-8111.

Due to the depth of the system additional fill will not be required. This lot slopes from south to north at approximately 5-10% which is away from the proposed house and any surrounding wells. There is sufficient area for the primary and reserve system within the radius of the testhole for the four bedroom single family residence. The existing field and tank will be abandoned in place. The proposed upgrade is in conjunction with a short plat being processed separately by the owner. There are no public or private wells within 100' of our proposed system location. There is neither surface water within 100' nor any known curtain drains within 50'. We do not expect that there will be any adverse effect on adjacent lots by the development of this system.
