RE: Proposed Septic System modification for Lake Hill Acres Lot 5
Dear Reviewer,
The above referenced property is currently served by an older, undocumented septic system and
unknown water supply. The owner is performing a significant remodel on the property and would like to
install a new septic system and private well.
We are proposing to install a 1250 gallon STEP tank, and a new drain field. If an old tank is discovered. it
will be decommissioned per moa requirements. The undocumented leachfield will be abandoned in
place.
An existing well was not located on the property and the water supply was unknown. A new well is
proposed as shown on the site plan and will be installed by a certified well driller.
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 the subject property.
Included with this letter is a permit application and design package, including plans, specifications,
calculations, and soils logs.
Thank you for your time in reviewing this permit request. Please do not hesitate to contact me at 907-854-
5558 or by email cgbalzarinigmail.com with any questions or concerns.
Sincerely,
C•- les : : ini, P.
