THE PIEDMONT FOOTHILLS UNIT S CHARACTERIZED BY ROLLING UPLAND TO RELATVELY STEEP TOPOGRAPHY. SOILS WITHIN THIS AREA MODERATELY DEEP, TO DEEP, AND GENERALLY WELL DRAINED ON THE PIEDMONT UPLAND AND FOOTHILLS OF THE BLUE RIDGE MOUNTAINS WITH SLOPES RANGING FROM 2-45%. THE SOILS ARE FORMED FROM WEATHERED GRANITES AND META -GRANITES OF THE BLUE RIDGE BASEMENT COMPLEX. THE SOILS ARE TYPICALLY CLAYEY AND SILTY SANDS AND SANDY CLAYS. F STORMINATER MANAGEMENT AND RUNOFF CONSIDERATIONS STORMWATER MANAGEMENT FOR THIS PROJECT WILL BE ADDRESSED THROUGH THE IMPLEMENTATION OF EROSION AND SEDIMENT CONTROL MEASURES AS REQUIRED. THE CONSTRUCTION OF THE PROJECT'S IMPROVEMENTS WILL NOT RESULT IN ADDITIONAL RUNOFF VOLUMES THAT REQUIRE STORMWATER QUALITY OR QUANTITY CONTROLS. CONSEQUENTLY, NO STORMWATER TRAPS OR BASINS ARE REQUIRED, TEMPORARY SEEDING AND SURFACE RESTORATION WILL BE PERFORMED AS WATER MAIN INSTALLATION PROCEEDS. FINAL RESTORATION WILL FOLLOW TESTING, DISINFECTION, AND ACCEPTANCE OF THE NEW WATER MAINS BY THE ACSA. CONS TR UCTION OF A SILT PENCE ( TIIOUT WTIZE SUPPORT) 1. SET THE STAKES 2.
