Re:
Riverview Lot 12, Block 6
Narrative & Permit Revision Application
Dear Mr. Cross:
We are requesting a design revision to the septic permit issued on the above referenced
property. The owner wishes to utilize the lower portion of his lot, eliminating the need for a
lift station. Attached you will find additional test hole logs and perc tests to support the
revision. The well is now located above the house. The proposed revised septic system will
have very limited impact on adjacent properties for the following reasons:
The surrounding lots are large, allowing sufficient room for septic sites. The lot
is adjoined by the Chugach State Park.
Immediate neighboring septic systems are all +30' distance.
Reserve space is adequate, due to absorption capacity.
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.
Sincerely,
Louis Butera, P.E.

Re: Riverview Lot 12, Block 6
Narrative & Permit Application
Dear Mr. Cross:
The proposed well mid 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.
Sincerely,
Louis Butera, P.E.
