Box 196650 Anchorage, AK 99519 Re: Benson Lot 4 Narrative & Permit Application Dear Mr. Cross: The proposed well and septic system will have very limited impact on adjacent properties for the following reasons: 1. The surrounding lots are large, allowing sufficient room for septic sites. 2. Immediate neighboring septic systems are all +30' distance. 3. Reserve space is adequate, due to absorption capacity. 4. Drainage will not be affected and is not a major consideration in our design. If you have any questions please call our office at 694-5195.
