DEPTH OF WATER TABLE : AVERAGE NATURAL GROUND ELEVATION = 30 AVERAGE WATER TABLE ELEVATION = 10 DEPTH TO WATER TABLE = 20 F HISTORY OF PAST USES IN PROJECT AREA: THE PAST AND CURRENT USE OF THE PROJECT SITE AND THE AREAS SURROUNDING IT IS AGRICULTURAL . INTENSITY AND EXTENT OF PROPOSED DEVELOPMENT : THE OWNER IS SUBDIVIDING APPROXIMATELY 254 . 4 ACRES INTO 6 PARCELS . EACH PARCEL IS APPROXIMATELY 40 ACRES OF ROW CROPS . PARCEL 1 ALREADY HAS A HOME AND SOME ACCESORY BUILDINGS . THE EXTENT OF THIS PROJECT IS TO BUILD A HOMESITE ON EACH OF THE REMAINING PARCELS . ENGINEER ' S OPINION OF SOIL SUITABILITY : A PERCOLATION TEST WAS PERFORMED ON ALL OF THE PARCELS . THE TESTS FOR PARCELS 1 , 2 AND 6 DID NOT PASS THE MINIMUM REQUIRED PERCOLATION RATE AND WERE RETESTED AT THE LOCATIONS SHOWN ON MAP ( SHEET 9 ) . A POSSIBLE EXPLANATION FOR THE ABOVE-MENTIONED TESTS FAILING IS THAT THE GROUND IN THE AREA IN WHICH THESE TESTS WERE PERFORMED COULD OF BEEN COMPACTED BY THE OPERATION OF HEAVEY EQUIPMENT AT THE TIME THE HIGHWAY WAS CONSTRUCTED. THE RETEST OF PARCEL 6 ONLY PERCOLATED 1 /4 INCH IN THE LAST HALF HOUR OR 120 MINUTES PER INCH . PRIOR TO THAT IT PERCOLATED 1-1 /2 INCHES, 1-1 /2 INCHES AND 1 INCH FOR THE THREE HALF HOUR PERIODS PRECEEDING THE LAST HALF HOUR . THE PERSON PERFORMING THE TEST SHOULD HAVE REFILLED THE WATER , SINCE 4 INCHES HAD PERCOLATED AND THERE WAS LITTLE WATER LEFT IN THE HOLE FOR THE LAST HALF HOUR . ON THIS BASIS WE ARE ACCEPTING THE RATE FROM THE HALF HOUR JUST PRIOR TO THE LAST HALF HOUR . FROM THE INFORMATION CONTAINED HEREIN , WE FIND THAT THE SOIL AT THIS PROJECT SITE IS SUITABLE FOR THE EXISTING AND PROPOSED DOMESTIC SEPTIC SYSTEMS AND THAT THE USE OF THESE SYSTEMS WILL NOT ADVERSELY AFFECT THE QUALITY OF THE GROUND WATER . k M.-'�_ QROFEss/ #0 NNCE r - 2 rrlZ b4' 7� ; ,3 NO. 14,269 � EXe,3-31-43 J,]glF C/V 1\' OF c SHEET 1
