THE PROJECT WILL INCLUDE THE CONSTRUCTION OF THE PUMP STATION AND A WATER PIPELINE FROM THE NEW PUMP STATION TO A POINT APPROXIMATELY 1,000 FEET DOWN WOODBURN ROAD, CONNECTING TO AN EXISTING RWSA WATER LINE. AN EXISTING TANK DISCHARGE STRUCTURE AND DITCH ON RWSA'S PARCEL WILL BE REPLACED WITH A BURIED STORM PIPE AND ADEQUATE DISCHARGE CHANNEL. AN EXISTING PUMP STATION ALONG BARRACKS ROAD WILL BE DEMOLISHED, AND REPLACED WITH TWO BURY HYDRANT ASSEMBLIES FOR EMERGENCY PUMP CONNECTION. 6. AFTER ACHIEVING ADEQUATE STABILIZATION, THE TEMPORARY E&S CONTROLS WILL BE CLEANED UP AND REMOVED. EXISTING SITE CONDITIONS THE NEW PUMP STATION PARCEL HAS PREVIOUSLY BEEN DISTURBED FOR INSTALLATION OF RWSA'S EXISTING SOUTH RIVANNA 1.0 MILLION GALLON ELEVATED WATER TANK. THE NEW STORM WATER PIPE AND DITCH WILL IMPROVE THE EXISTING DITCH TO ADDRESS EROSION. THE SITE DRAINS AWAY FROM THE TANK AND ULTIMATELY TOWARDS THE SOUTH FORK RIVANNA RIVER RESERVOIR TO THE NORTH. THE MAJORITY OF THE SITE IS FORESTED. THE WATER PIPELINE WILL PRIMARILY BE CONSTRUCTED ALONG THE VEGETATED SOUTH SHOULDER OF WOODBURN ROAD, PARTIALLY WITHIN THE WOODBURN ROAD RIGHT-OF-WAY AND ADJACENT TO OR WITHIN RESIDENTIAL PARCELS. THE EXISTING PUMP STATION/DEMO SITE IS LOCATED ON THE EDGE OF A RESIDENTIAL PARCEL, AND DRAINS PRIMARILY TOWARD BARRACKS ROAD. TOTAL DISTURBANCE FOR THE PUMP STATION AND PIPELINE INSTALLATION ALONG WOODBURN ROAD AND THE STORM WATER CONVEYANCE SYSTEM ON RWSA'S PARCEL WILL BE APPROXIMATELY 0.724 ACRES. TOTAL DISTURBANCE AT THE EXISTING PUMP STATION SITE AT BARRACKS ROAD WILL BE APPROXIMATELY 0.051 ACRES. ADJACENT PROPERTY WOODBURN ROAD BORDERS THE PUMP STATION SITE TO THE SOUTH. A RESIDENTIAL PROPERTY WITH A SINGLE FAMILY HOME BORDERS THE SITE TO THE WEST. VACANT RESIDENTIAL LAND ABUTTING THE SOUTH FORK RIVANNA RIVER RESERVOIR BORDERS THE SITE TO THE NORTH. A VACANT RWSA PARCEL BORDERS THE SITE TO THE EAST. VACANT RESIDENTIAL PROPERTY OWNED BY THE COMMONWEALTH OF VIRGINIA, VDOT RIGHT OF WAY DIVISION IS IMMEDIATELY ACROSS WOODBURN I ROAD FROM THE PUMP STATION SITE. THE PIPELINE ALIGNMENT IS WITHIN PROPERTY OWNED BY THE COMMONWEALTH OF VIRGINIA, VDOT RIGHT OF WAY DIVISION. THE EXISTING PUMP STATION/DEMO SITE IS LOCATED ON A SINGLE-FAMILY HOME RESIDENTIAL PARCEL IN A PROPOSED EASEMENT. OFF-SITE AREAS TOPSOIL MUST BE `.STRIPPED FROM GRADED AREAS AND STOCKPILED FOR USE IN FINAL GRADING AND PERMANENT STABILIZATION. THE STOCKPILE WILL BE STABILIZED WITH TEMPORARY VEGETATION TO PREVENT SOIL LOSS AND SEDIMENT TRANSPORT FROM THE STOCKPILE ITSELF UNTIL NEEDED. SOILS SEE SOILS MAP THIIS SHEET. THE PREDOMINANT 'SOILS ON THE SITE ARE PACOLET SANDY LOAMS, WITH 2 TO 7 PERCENT SLOPES AND 7 TO 15 PERCENT SLOPES. PACOLET 1S A VERY DEEP WELL DRAINED SOIL. TYPICALLY THE SURFACE LAYER IS SANDY LOAM ABOUT 6 INCHES THICK. THE SURFACE LAYER HAS A MODERATELY LOW CONTENT OF ORGANIC MATTER. THE SLOWEST PERMEABILITY IS MODERATE. IT HAS A MODERATE AVAILABLE WATER CAPACITY AND A LOW SHRINK SWELL POTENTIAL. THIS SOIL IS NOT FLOODED AND IS NOT PONDED. THE SEASONAL HIGH WATER TABLE IS AT A DEPTH OF MORE THAN 6 FEET. THE LAND CAPABILITY CLASSIFICATION IS 2e. THE VIRGINIA SOIL MANAGEMENT GROUP IS X. THIS SOIL IS NOT HYDRIC. CRITICAL EROSION /AREAS THE CRITICAL AREAS ON SITE ARE THE LOCATIONS NOTED AS STEEP SLOPES ON SHEET 3. EROSION & SEDIMENT CONTROL MEASURES ALL EROSION AND :SEDIMENT (E&S) CONTROL PRACTICES AND DEVICES DESCRIBED HEREIN SHALL CONFORM TO THE CURRENT VIRGINIA E&S CONTROL HANDBOOK AND THE ALBEMARLE COUNTY CODE AND DESIGN STANDARDS MANUAL, LATEST EDITION(S). STRUCTURAL PRACTICES 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 CONSTRUCTION ENTIRANCE 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 MAYS 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 12 -INCH CULVERT AT APPROXIMATE STATION 7+23, TO PROTECT THE DOWNSTREAM SIDE FROM EROSION. ROCK CHECK DAM :3.20: TWO ROCK CHECK DAMS WILL BE INSTALLED ON THE DOWNSTREAM END OF THE DITCH ALONG WOODBURN ROAD ON BOTH SIDES OF THE STREET TO REDUCE THE VELOCITY OF CONCENTRATED STORMWATER FLOWS AND TRAP SEDIMENT GENERATED, MAINLY BY PONDING OF THE STORMWATER RUNOFF. A ROCK CHECK DAM WILL ALSO BE USED TO PREVENT RUNOFF FROM THE SITE AT THE SOUTH END OF THE EXISTING DITCH. SOIL STABILIZATIOiA MATTING 3.36: SOIL STABILIZATION MATTING WILL BE INSTALLED IN AREAS OF STEEP SLOPES DISTURBED BY CONSTRUCTION AS SHOWN ON SHEET 13. 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 ENTfRANCE 3.02: A CONSTRUCTION ENTRANCE SHALL BE INSTALLED AT THE ENTRANCE TO THE SITE. OTEMPORARY 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 CONSTRUCTION ENTIRANCE 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 MAYS BE REQUIRED BY THE EROSION AND SEDIMENT CONTROL PROGRAM ADMINISTRATOR.

SOIL STABILIZATIOiA MATTING 3.36: SOIL STABILIZATION MATTING WILL BE INSTALLED IN AREAS OF STEEP SLOPES DISTURBED BY CONSTRUCTION AS SHOWN ON SHEET 13. 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 JOB SUPERINTENDENT SHALL BE RESPONSIBLE FOR THE INSTALLATION AND MAINTENANCE OF ALL E&S CONTROL PRACTICES. 6. AFTER ACHIEVING ADEQUATE STABILIZATION, THE TEMPORARY E&S CONTROLS WILL BE CLEANED UP AND REMOVED. 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, THE 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. (PROJECT NARRATIVE CONTINUED ON SHEET 10A) eeoww�,LT H of CHARLES FRANK VOTAVA z -p Lic.

PLANT MATERIALS • THE MULCH LAYER SHOULD BE INSPECTED FOR AREAS OF EROSION AND MATERIAL REPLACED AS NEEDED. • THE ENTIRE MULCH LAYER SHOULD BE REPLACED EVERY TWO TO THREE YEARS IN THE SPRING. WHEN THE MULCH LAYER IS REPLACED, THE PREVIOUS LAYER SHOULD BE REMOVED FIRST. • PLANT MATERIAL UPKEEP INCLUDES ADDRESSING PROBLEMS ASSOCIATED WITH DISEASE OR INSECT INFESTATIONS, REPLACING DEAD PLANT MATERIAL, AND ANY NECESSARY PRUNING.
