EROSION & SEDIMENT CONTROL MEASURES ALL EROSION AND SEDIMENT (E&S) CONTROL PRACTICES AND DEVICES DESCRIBED HEREIN SHALL CONFORM TO THE CURRENT VIRGIINIA E&S CONTROL HANDBOOK AND THE ALBEMARLE COUNTY CODE AND DESIGN STANDARDS MANUAL, LATEST EDITIONI(S). STRUCTURAL PRACTICES PAVED CONSTRUCTION ENTRANCE 3.02: A PAVED CONSTRUCTION ENTRANCE SHALL BE INSTALLED AT THE ENTRANCE TO THE SITE. TEMPORARY PAVED WASH RACK: A MINIMUM WATER TAP OF 1" MUST BE INSTALLED WITH A MINIMUM 1" BALL -COCK SHUTOFF VALVE SUPPLYING A WASH HOSE WITH A DIAMETER OF 1.5" FOR ADEQUATE CONSTANT PRESSURE. WASH WATER MUST BE CARRIED AWAY FROM THE ENTRANCE TO AN APPROVED SETTLING AREA TO REMOVE SEDIMENT. ALL SEDIMENT SHALL BE PREVENTED FROM ENTERING STORM DRAINS, DITCHES, OR WATER COURSES. SHOULD THE TEMPORARY PAVED CONSTRUCTION ENTRANCE NOT BE MAINTAINED PROPERLY OR AN EXCESSIVE AMOUNT OF SOIL FOUND TRACKED ONTO THE PUBLIC ROADWAY, THEN A PAVED CONSTRUCTION ENTRANCE, WATER TANKER TRUCK WITH 2 PRESSURE WASHERS AND A SETTLING AREA MAY BE REQUIRED BY THE EROSION AND SEDIMENT CONTROL PROGRAM ADMINISTRATOR. SILT FENCE 3.05: SILT FENCE SEDIMENT BARRIERS WILL BE INSTALLED AS SHOWN TO FILTER SEDIMENT -LADEN RUNOFF FROM SHEET FLOW TO PREVENT SEDIMENT LEAVING THE SITE. SILT FENCE CULVERT INLET PROTECTION 3.08-1: A SILT FENCE SHALL BE PLACED PERPENDICULAR TO THE 18-INCH CULVERT AT APPROXIMATE STATION 5+48, TO PROTECT THE DOWNSTREAM SIDE FROM EROSION. SOIL STABILIZATION MATTING 3.36: SOIL STABILIZATION MATTING WILL BE INSTALLED IN AREAS OF STEEP SLOPES NEAR STATION 3+38 TO MINIMIZE DISTURBANCE BY CONSTRUCTION. TREE PROTECTION 3.38: A FENCE BARRIER IS TO BE PLACED AROUND THE TREES WHICH WILL NOT BE DISTURBED TO PROTECT THE TREES FROM CONSTRUCTION EQUIPMENT AND SOIL COMPACTION. MANAGEMENT STRATEGIES 1. CONSTRUCTION WILL BE SEQUENCED SO THAT GRADING OPERATIONS CAN BEGIN AND END AS QUICKLY AS POSSIBLE. 2. SEDIMENT TRAPPING MEASURES WILL BE INSTALLED AS A FIRST STEP IN GRADING AND WILL BE SEEDED AND MULCHED IMMEDIATELY FOLLOWING INSTALLATION. 3. TEMPORARY SEEDING OR OTHER STABILIZATION WILL FOLLOW IMMEDIATELY AFTER GRADING. 4. AREAS WHICH ARE NOT TO BE ._;DISTURBED WILL BE CLEARLY MARKED BY FLAGS, SIGNS, ETC. 5. THE VPDES PERMIT OPERATOR SHALL BE RESPONSIBLE FOR THE INSTALLATION AND MAINTENANCE OF ALL E&S CONTROL PRACTICES. 6. UPON ,AUTHORIZATION FROM DESIGNATED COUNTY INSPECTOR, REMOVE ALL SEDIMENT CONTROLS AND STABILIZE ALL DISTURBED AREAS. PERMANENT STABILIZATION ALL AREAS DISTURBED BY CONSTRUCTION SHALL BE STABILIZED WITH PERMANENT SEEDING (PRACTICE 3.32) OR MATTING (PRACTICE 3.36), AS REQUIRED, IMMEDIATELY FOLLOWING FINISH GRADING. MAINTENANCE IN GENERAL, ALL E&S CONTROL MEASURES WILL BE CHECKED DURING AND AFTER EACH SIGNIFICANT RAINFALL. IN PARTICULAR, THIS SILT FENCE WILL BE CHECKED REGULARLY FOR UNDERMINING OR DETERIORATION OF THE FABRIC. SEDIMENT SHALL BE REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHES HALF WAY TO THE TOP OF THE BARRIER. SEDIMENT CONTROL PROGRAM - PHASE I PHASE I E&S CONTROL PLAN IS INTENDED TO ESTABLISH PERIMETER CONTROL MEASURES, INCLUDING SILT FENCE. 1. INSTALL PAVED CONSTRUCTION ENTRANCE AND PERIMETER CONTROLS, INCLUDING SILT FENCE AS SHOWN ON CONSTRUCTION PLAN SHEETS. 2. CLEAR THE SITE TO NO MORE THAN THE LIMITS OF CONSTRUCTION SHOWN ON THE CONSTRUCTION PLANS. SEDIMENT CONTROL PROGRAM - PHASE II PHASE II EROSION AND SEDIMENT CONTROL PLAN IS INTENDED TO PROVIDE CONTROL MEASURES DURING THE FINAL STAGES OF IMPROVEMENTS. 1. BEGIN GROUND STORAGE TANK, WATER PUMP STATION AND PIPELINE CONSTRUCTION. 2. INSPECT CONTROL MEASURES AT LEAST ONCE DAILY. 3. STABILIZE WITH PERMANENT SEEDING AFTER TRENCH BACKFILL AND COMPACTION. USE SOIL STABILIZATION MATTING WHERE CALLED FOR BY THE DRAWINGS. 4. REMOVE CONTROL MEASURES ONLY AFTER ALL DISTURBED AREAS HAVE BEEN STABILIZED AND ONLY AS APPROVED AND DIRECTED BY THE COUNTY INSPECTOR. PRE AND POST DRAINAGE AREAS THE PRE AND POST DRAINAGE AREAS ARE SHOWN ON THE SITE PLAN ON SHEET 4. THE MAJOR DRAINAGE AREAS REMAIN UNCHANGED IN THE PRE AND POST CONDITIONS, WHICH FLOWS TO THE SOUTHEAST AND IS CONVEYED INTO THE ADJACENT PROPERTY AND AN EXISTING STREAM THROUGH SHEET FLOW OR THE EXISTING DITCH (TO BE MODIFIED AS PART OF THE PROJECT). CONSTRUCTION OF THE NEW GROUND STORAGE TANK AND THE PUMP STATION WILL CAUSE A PORTION OF DRAINAGE AREA TO BE CONVEYED INITIALLY TO THE NEW BIORETENTION FACILITY, BUT THE OUTFALL OF DRAINAGE AREA WILL REMAIN UNCHANGED. SILT FENCING DURING CONSTRUCTION WILL PROTECT PROPERTY FROM RUNOFF. _ GLENMORE GROUND STORAGE TANK, PUMP STATION, AND WATER MAIN PROJECT (PROJECT NO. 2013-04) I�H' OF � CHARLES FRANK VOTAVA Lic.
