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.
