Dear Mr. Cox:

On September 3 and 4, 1974 percolation tests were run
on your property as shown on the enclosed sketch map.
Tests consisted of one soils boring to eight feet in
depth and six test holes 24 to 36 inches in depth.
Soils encountered (at test hole 6) were topsoil, red
sand, gray sandy clay, gray clay and gray clay till.
No standing water was observed.
Percolation rates nearest the proposed drain field are
40 minutes per inch. At this rate the drain field area
required is 300 square feet for each proposed bedroom.
The proposed drain field shown allows for four bedrooms
assuming a trench bottom width of two feet. Percolation
rates at the other test holes were half of this or 20
minutes per inch. A dre:n field at the alternate site
shown would require a lift station but would need ap-
proximately one half the area of the first choice. Top-
ographic contours shown are approximate.
The stated percolation rate is an average of rates at the
locations shown and no guarantee is implied or expressed
that these conditions exist for the entire proposed drain
field area.
If we can be of further help, please advise.
Sincerely,
EUGENE A. HICKOK AND ASSOCIATES
