SUBJECT: Lot 11, Section.21, T12N, R3W
Septic System Construction Permit SW970098
The owner of the subject property is currently subdividing his lot into three separate lots.
Due to the location of the new lot line we are forced.to move the new absorption trench to a
location different from that shown on the original design and subsequent permit. We are
therefore requesting the new absorption trench be placed at the location shown on the
attached plan.
A testholeplaced at the end of the new trench revealed no bedrock nor water to a depth of
19'. We encountered a silty sand to a depth of 6.5' underlain by a clean poorly graded
sand with small amounts of silt and gravel. This material is ideal for an absorption trench.
A percolation test performed on the material indicated an absorption rate of 1.5 minutes per
inch. We are.proposing to place a 32' l°ng` absorption trench with 6' effective depth from
7' to 13' below the surface.. This area is much better for the absorption trench than the
area originally shown because of the sandy material encountered.
A new septic tank will be placed becaUse the existing tank was found unsuitable for reuse.
Please revise' the perrmt issued for this lot to allow placement of the new trench at the
location and configuration shown. Thank you for your assistance with this matter.
