RE: Proposed Septic System replacement for WYNTER PARK#1 B2 L20
Dear Reviewer,
The above referenced property is currently being developed. The owner would like to install a new septic
system to go with the new home. The subject parcel and adjacent parcels are served by a public well.
We are proposing to install a new septic tank, and a new drainfield. The drainfield will be sized for 3
bedrooms.
There is an existing septic system on the lot. The existing tank was located, but the absorption system
appears to reside on lot 21. The existing tank will be demolished per moa requirements.
Included with this letter is a permit application and design package, including plans, and calculations.
A test hole was excavated and revealed good soils with no groundwater encountered.
The Homeowner intends to install the septic system himself.
Thank you for your time in reviewing this permit request. Please do not hesitate to contact me at 907-854-
5558 or by email cgbalzarini@gmail.com with any questions or concerns.
No significant impacts to adjacent properties are likely due to lot sizes and the nearby public water
system.
Sincerely,
Charles Balzarini, PE
