ADJACENT PROPERTIES: THE PROPOSED SEPTIC SYSTEM IS LOCATED OVER 123' FROM THE ADJACENT PROPERTY TO THE WEST (TRACT 1. BLUE SKY ESTATES, 13.8 ACRES) 450' FROM THE ADJACENT LOT TO THE NORTH (CHUGACH STATE PARK); 452' FROM THE ADJACENT PROPERTY TO THE EAST (A VERY LARGE UNDEVELOPED TRACT), AND 87' FROM THE ADJACENT UNDEVELOPED PROPERTY TO THE SOUTH (LOT 2, RAVINE FOREST ESTATES, 4 ACRES). 3.

EXISTING WELLS: PUBLIC RECORDS INDICATE THAT WELLS IN THE AREA ARE FINDING WATER BETWEEN 200' AND 390'. YIELD IN THESE WELLS VARY BETWEEN 1.6 AND 6 GALLONS PER MINUTE. DUE TO THE LOW DENSITY OF DEVELOPMENT IN THIS AREA, THE PROPOSED WELL SHOULD BE ABLE TO PROVIDE THE REQUIRED FLOW WITH OUT ADVERSE IMPACT TO ANY OF THE ADJACENT WELLS. THE 100' PROTECTIVE WELL RADIUS WILL NOT IMPACT ADJACENT PROPERTIES. 5. SOiL AND WATER TABLE CONDITIONS: A SINGLE TEST HOLE WAS DUG TO A DEPTH OF 16.2 FEET. THE SOILS WERE UNIFORM FOR THE FULL DEPTH OF THE TEST PIT; CONSISTING OF SITLY SANDY GRAVEL (ABOUT 12% SITLY). THE PERCOLATION RATE WAS MEASURED AT 8 MINUTES PER INCH. THE WATER TABLE WAS MON[TURED OVER A 13 MONTH PERIOD WHICH ENCOMPASSED THE MONTHS WITH THE HIGHEST PRECIPITATION. NO GROUND WATER WAS NOTED DURNG ANY OF THE INSPECTIONS. THIS SITE WiLL SUPPORT AN ON SITE WASTEWATER DISPOSAL SYSTEM FOR THE SPECIFIED HOUSE. CARE SHOULD BE TAKEN DURING CONSTRUCTION TO PROTECT THE SIDE WALLS OF THE TRENCHS FROM SMEARING WHICH CAN OCCUR WHEN THE SIL3Y CONTENT IS A HIGH AS NOTED. THE SIDEWALLS SHOULD BE SCARIFIED TO ENSURE THAT THE PERCOLATION RATES IS MAINTAINED. 6. SEPTIC SYSTEMS: THERE ARE NO EXISTING SEPTIC SYSTEMS WITHIN 200' OF THE PROPERTY LINE. THE PROPOSED SYSTEM WILL NOT ADVERSELY IMPACT ANY OF THE ADJACENT PROPERTIES, 7~ DRAINAGE CHANNEL, PONDS & STREAMS: THERE IS A STREAM WHICH RUNS SOUTH TO NORTH LOCATED ALONG THE EASTERLY SIDE OF THE SUBJECT LOT.
