We received a telephone request from Mr. Bob Mason today relative to percolation
tests taken at the above address by Braun Engineering Testinr The percolation
testa taken approximately a week ago failed to meet minimum requirements for
soil absorption systems. It was indicated that freezing temperatures and frost
may have had an adverse affect on the test results. Mr. Mason requested some
kind of interims or contingency aprroval of the septic system until summer, so
he could get a building permit.
We checked with Mr. Ron Schaffer of Braun Engineering Testing (941-5600) who
reviewed the test procedures. Mr. Schaffer informed us that the soil boring in-
dicated sandy clay till material which he said was a marginally accepted soil.
Mr. Shaffer also stated that freezing temperatures and frost may possibly had an
adverse affect on the test results, but he further stated that "- - - - it is to
close to call." He can offer no other conclusive collaborating opinion of the
acceptability of the soils for septic system design.
We recommend that no building permit be granted to Mason Builders for the above
subject lot until satisfactory evidence of acceptable soils for a soil absorption
system has been submitted.
Yours very truly, !! _�
