RE: Proposed Septic System for RABBIT CREEK VIEW AND HEIGHTS BLOCK 7H LOT 29A
Dear Reviewer,
The above referenced property is currently vacant and the owner plans to develop the lot and construct a
new 2 bedroom home served by onsite water and wastewater utilities.
We are requesting approval to install a well, septic tank, and leachfield.
We are proposing to install a new 1000 gallon tank, and a new 2 bedroom shallow trench system.
Replacement leachfield sites are also shown.
The soils are silty sand material with some clay. A sand~'~g~l approximately 2' thick overlays the silty
soils. The organics have been stripped from the lot at the test hole and leachfield location. The silty soils
could be considered marginal for septic system installation, however the system will be installed high in
the soil column to maximize use of the good soils. The system is sized for 2 bedrooms and is oversized.
A sand liner will be installed to provide some filtration prior to effluent reaching and plugging the sitly soil.
Surveyed contours indicate a steep slope approximately 40' down slope from the lower leachfield trench.
We are requesting that the separation distance from the leachfield to the steep slope be waived from the
required 50' to 40' minimum. A cross section included with this submittal details the slopes, and how fill
will be placed.
Included with this letter is a permit application and design package, including plans, specifications,
calculations, and soils logs.
The installation of the proposed septic system will not adversely impact adjacent lots, which are currently
undeveloped. Changes to drainage patterns are not anticipated.
Thank you for your time in reviewing this permit request. Please do not hesitate to contact me at 907-854-
5558 or by email cqbalzariniC, qmail.com with any questions or concerns.
Sincerely,
Charles Balzarini, PE
