Anchorage, Alaska
Project: Percolation Test- Lot 58, Sec. 22, T13N, R3W, S.M.
Dear Mr. Kohniak:
A percolation test has been performed on the subject lot. Test holes
at the base of the hill east of the building location indicates that this area is
not suitable for on-site sewage disposal. The higher ground north of the
building site was investigated. The test data are shown on the attached sheet.
The percolation rate was determined to be 1" per less than 1 minute.
The nature of the soils are such that the test hole could not be advanced
to the desired 8 feet to determine the elevation of a water table. Should a water
table be encountered during installation, the seepage pit must be desi§ned lo
allow 2 feet of gravel between the water table and the bottom of the pit. If
this should occur, [:he Greater Anchorage Area Borough Health Department or
we will be available for advice.
Very truly yours,
A DAIVl S, CORTHELL, LEE, WINCE
