77-S10A <br /> Centurion Company -3- Aaii}U3 t 11 , 1 Vis; <br /> • <br /> Through visual observations of the topography, three wetland <br /> areas are evident on the tract. Th: seasonal high water levels <br /> for those wetlands appear to range from 950± to 958±. The <br /> designated drain field areas in Lots 1 through 5 and 7, adjacent <br /> to those wetlands will be from 8 to 20 feet higher in elevation <br /> from that of those seasonal high water levels. <br /> Based on data available, as well as observations and analysis, <br /> it is our professional opinion that groundwater conditions in <br /> designated drain field areas are well within City of Orono <br /> ordinance requirements. <br /> Sanitary System Analsis <br /> The attached tabulation and sketches indicate areas where <br /> satisfactory percolation results were obtained in both primary <br /> and expansion areas on each of the lots. It is our professional <br /> opinion that those results indicate that a conventional drain- <br /> field system mestji .� na. ce c 11ha �A•ca'*p <br /> nrs- *f rn,.J.!?
