Soils Investigation
Dear Mr. Ellis:
As per your request, a soils investigation was performed on the above
legally described lot for the pupose of determining the suitability for
on-site sewage disposal.
The subject lot 'as is' presently contains approximately 5 acres and is
planned to be subdivided into two lots, one of which will be approximately
3 acres and the other 2± acres. The two here lot will be on the east side
surrounding the existing home and the three acres will be on the west side.
The existing two acre parcel has a well and septic system installed, which
appears to be functioning adequately. Therefore, only one test hole was
felt necessary ~n the area of the proposed new home location on the west
end of the lot.
The property slopes gradually from west to east and has been developed for
present usage as barn and large horse arena. The top soil has been removed
on the majority of the area of the proposed 3 acre lot exposing a continuous
gravel underburden throughout the entire area...~
The test hole verified that the ~avel extends to at ,least classifiedl3 feet Wi~h~no,~.
ground water to tbat depth. The soil from 0 to 13 feet is
accordance with the Unified St)[~. Classificat~on 'as~nl] graded Sa~,~v
Grave] (GW). Therefore, the sept]C-.system for this subdivision sbon]d/15e
designed using an ai)sorption area of 85 sq~gre feet per bedroom. Whe~ the
system is installed, it woold be advisable to i~rovide at least 5:~feet of
cover over the absorption system or. provide some additional insulative cover
to deter frost. The system could be installed with the lower part of the
drainf~e]d belng below 9 feet Jf at the time of installation the lower level
from 13-16 feet denp is explored and no.ground water ~is enconntered.
In conclusion, it is my opinion that a septic system, if designed and installed
correctly and maintained adequately by pumping the septic tank regularly~ will
function adequately for the normal system life time.
Sincerely,
PENINSULA
