Pits are required to reach the sand <br /> layer,which appears to exist only on the easterly 125' of each parcel. <br /> i/ The Environmental Questionnaire signed by James Maier is included and shows no chemicals used <br /> since obtaining the parcel in 1999. The main use was pasture for grazing purposes. <br /> CONCLUSION <br /> IT IS IMPORTANT THE PITS ARE LOCATED IN THE SAND LAYER. THERE IS <br /> ADEQUATE SAND PRESENT TO SUPPORT A SINGLE FAMILY RESIDENCE. IF TWO <br /> SFR'S ARE CONSTRUCTED ON A PARCEL AND ONLY ONE SEPTIC SYSTEM IS <br /> CONSTRUCTED IT IS.RECOMMENDED THE ADVANTEX TREATMENT SYSTEM <br /> DESIGNED BY ORENCO SYSTEMS, INC.(OR EQUAL),BE CONSTRUCTED. <br /> ATTACHMENTS <br /> 3. <br /> i <br />
