THIS PROJECT PROPOSES TO DISTURB 0.97 ac. OF LAND. THE PROJECT WILL BEGIN ITS CONSTRUCTION WITH THE PROPOSED ESC MEASURES IMMEDIATELY FOLLOWING PLAN APPROVAL, WHICH IS ANTICIPATED TO BE IN THE FALL OF 2020. THE WORK IS ANTICIPATED TO BE COMPLETED WITHIN 12 MONTHS AND TO CONCLUDE IN THE FALL OF 2021. EXISTING SITE CONDITIONS: THE AREA OF THE PROPOSED DEVELOPMENT IS VACANT LOT MOSTLY COVERED BY DENSE VEGETATION. THE SITE GENERALLY SLOPES FROM THE SOUTHEAST TO THE NORTHWEST TOWARDS STONEY RIDGE ROAD. ADJACENT AREAS: THIS SITE IS BORDERED TO THE NORTH, EAST AND WEST BY COMMERCIAL OFFICE BUILDINGS. TO THE SOUTH IS A DOG DAYCARE BUILDING AND A MEDICAL SERVICES BUILDINGS. SILT FENCE, DIVERSIONS, SEDIMENT TRAPS, INLET CONTROLS AND VARIOUS OTHER ESC MEASURES ARE PROPOSED TO LIMIT THE POTENTIAL FOR CONTAMINATION OF THESE ADJACENT PROPERTIES. OFFSITE LAND DISTURBANCE: OFFSITE LAND DISTURBANCE IS LIMITED TO PUBLIC RIGHT-OF-WAY. CRITICAL AREAS: THE MANAGED STEEP SLOPES ON THE EASTERN PORTION OF THE SITE ARE CONSIDERED TO BE CRITICAL. THE CONTRACTOR SHALL GIVE EXTRA ATTENTION AND CAUTION IN AND AROUND THESE AREAS TO ENSURE CONSTRUCTION ACTIVITY DOES NOT DISTURB THESE EXISTING FEATURES. TREE PROTECTION FENCING, SILT FENCING, DIVERSIONS AND SEDIMENT TRAPPING DEVICES SHALL ALSO BE INSTALLED AS A FIRST STEP IN LAND DISTURBANCE TO ENSURE THESE CRITICAL AREAS ARE I�L1f��_1I�Iq�a SEQUENCE OF CONSTRUCTION: 1. CONTRACTOR SHALL NOTIFY THE ALBEMARLE COUNTY COMMUNITY DEVELOPMENT ENGINEERING DEPARTMENT TO SCHEDULE A PRE -CONSTRUCTION MEETING. 2. PRIOR TO DISTURBANCES, THE LIMITS OF DISTURBANCE SHALL BE FLAGGED AND THE TREE PROTECTION FENCING SHALL BE INSTALLED. 3. NO EROSION CONTROL MEASURES MAY BE REMOVED DURING THE CONSTRUCTION PROCESS WITHOUT THE APPROVAL FROM THE INSPECTOR ON THE PROJECT. 4. INSTALLATION OF THE PROPOSED CONSTRUCTION ENTRANCE SHALL OCCUR NEXT. THE CONTRACTOR SHALL APPLY CONSTRUCTION ROAD STABILIZATION AS NEEDED. CONTRACTOR SHALL ENSURE THE CONSTRUCTION ENTRANCE DRAINS TO AN ADEQUATE E&S MEASURE. THE CONTRACTOR SHALL UTILIZE THE NEARBY SEDIMENTTRAP #1 FOR VEHICULAR WASH OFF. CONSTRUCTION ENTRANCE TO BE INSTALLED WHERE CONSTRUCTION VEHICLE ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTING TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. 5. THE INITIAL ESC CONSTRUCTION MEASURES, AS SHOWN ON THE PHASE I EROSION & SEDIMENT CONTROL PLAN, SHALL BE INSTALLED NEXT. THE CONTRACTOR SHALL BEGIN BY INSTALLING THE PERIMETER SILT FENCE AND TREE PROTECTION. PERIMETER MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 6. ONCE THE PERIMETER EROSION CONTROL MEASURES HAVE BEEN INSTALLED, AND THE COUNTY INSPECTOR HAS APPROVED THESE MEASURES, THE CONTRACTOR SHALL BEGIN LIGHT CLEARING. THE CONTRACTOR SHALL BEGIN BY CLEARING THE AREAS IN THE VICINITY OF SEDIMENT TRAP #1, AND THE AREAS REQUIRED TO ACCESS IT. FOLLOWING THIS MINOR CLEARING, THE CONTRACTOR SHALL INSTALL SEDIMENT TRAP #1 AND STRUCTURES 1-4, 9, 10 & A PORTION OF STR. 5 TO THE NEAREST PIPE (OUTSIDE OF SEDIMENT TRAP #'1's FOOTPRINT). THE TIMING OF THESE STRUCTURES' CONSTRUCTION WILL AVOID FUTURE DISTURBANCES TO THE TRAP IN SUBSEQUENT ESC PHASES. STRUCTURES 4 & 5 SHALL BE SEALED WATERTIGHT TEMPORARILY UNTIL THE TRAP IS CONVERTED TO A PERMANENT FACILITY. THIS WILL ALLOW STRUCTURE 10 TO CONTINUE TO DIVERT THE OFFSITE, UPLAND, CLEAN RUNOFF TO THE EXISTING STORM SEWER (TO REMAIN) WHEN THE ONSITE PORTION OF THE EXISTING CONCRETE DITCH IS REMOVED FOR THE INSTALLATION OF SEDIMENT TRAP #1. THIS SEQUENCING WILL HONOR THE EXISTING FLOW PATTERNS AND WILL PREVENT CLEAN WATER RUNOFF FROM BEING DISCHARGED DIRECTLY ONTO THE CONSTRUCTION SITE. THE CONTRACTOR SHALLTHEN INSTALLTHE DIVERSIONS. ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE I EROSION CONTROL PLAN SHALL ALSO BE CONSTRUCTED AT THIS TIME. ONCE ALL THE PHASE I EROSION CONTROL ITEMS HAVE BEEN INSTALLED & ARE OPERATIONAL, DRAINAGE IS PROPERLY CONVEYED TO THE APPROPRIATE MEASURES, AND THE ESC INSPECTOR HAS GRANTED APPROVAL, THE CONTRACTOR CAN BEGIN CLEARING THE REMAINDER OF THE SITE. TEMPORARY SEEDING, PERMANENT SEEDING AND DUST CONTROL SHALL BE IMPLEMENTED AS REQUIRED. 8. AFTER CLEARING THE PROPOSED AREAS, THE CONTRACTOR CAN PROCEED TO PHASE II OF THE EROSION & SEDIMENT CONTROL PLAN. THE CONTRACTOR SHALL BEGIN ROUGH GRADING THE SITE TO THE CONTOURS SHOWN ON THE PHASE II EROSION & SEDIMENT CONTROL PLAN. MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 9. THE CONTRACTOR SHALL INSTALL ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE II EROSION CONTROL PLAN. ONCE THE PARKING LOT HAS BEEN ROUGH GRADED, THE CONTRACTOR CAN INSTALL THE REMAINDER OF STRUCTURE 5 & STRUCTURE 6. AT THIS TIME, STRUCTURES 2,4 & 6 SHALL CONTINUE TO REMAIN TEMPORARILY WATERTIGHT TO ENSURE DIRTY WATER IS NOT MIXED WITH THE CLEAN WATER DISCHARGING FROM THE SITE. TEMPORARY SEEDING, PERMANENT SEEDING AND DUST CONTROL SHALL BE IMPLEMENTED AS REQUIRED. 10. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UNDISTURBED) FOR LONGER THAN 30 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. 11. ONCE THE SITE IS ROUGH GRADED, THE CONTRACTOR SHALL BEGIN PHASE III OF THE EROSION & SEDIMENT CONTROL PLAN. THE CONTRACTOR CAN BEGIN INSTALLATION OF THE UTILITIES, CURB AND GUTTER, AND ROADS. INLET PROTECTION SHALL ALSO INSTALLED AS THE STORM SEWER IS CONSTRUCTED. INLET PROTECTION SHALL BE INSPECTED AFTER EACH RAINFALL EVENT AND REPAIRS SHALL BE MADE AS NEEDED. IF THE STONE FILTER BECOMES CLOGGED WITH SEDIMENT SO THAT IT NO LONGER ADEQUATELY PERFORMS ITS FUNCTION, THE STONE MUST BE PULLED AWAY AND CLEANED AND/OR REPLACED. 12. ONCE PHASE III OF CONSTRUCTION IS COMPLETE, THE SITE IS STABILIZED AND THE INSPECTOR HAS GIVEN APPROVAL, THE CONTRACTOR CAN THEN CONVERTTHE SEDIMENTTRAPS INTO THE PROPOSED SWM FACILITIES. AT THIS TIME, THE CONTRACTOR CAN REMOVE THE REMAINDER OF THE EROSION & SEDIMENT CONTROL MEASURES. NO ITEM SHALL BE REMOVED, THROUGHOUT ALL PHASES OF CONSTRUCTION, UNLESS THE UPSTREAM AREAS ARE STABILIZED AND THE INSPECTOR GIVES PERMISSION. 13. THE CONTRACTOR SHALL MAINTAIN ALL EROSION CONTROL MEASURES AS SPECIFIED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, REMOVING ONLY WHEN APPROVED BY THE LOCAL PROGRAM ADMINISTRATOR IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. 14. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL PROGRAM ADMINISTRATOR. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND SEDIMENTATION.

THE PURPOSE OF THIS LAND DISTURBANCE ACTIVITY IS FOR THE CONSTRUCT70N OF A PARKING LOT AND A 2,000 COMMERCIAL OFFICE BUILDING. THIS PROJECT PROPOSES TO DISTURB 0.97 cc. OF LAND. THE PROJECT WILL BEGIN ITS CONSTRUCTION WITH THE PROPOSED ESC MEASURES IMMEDIATELY FOLLOWING PLAN APPROVAL, WHICH IS ANTICIPATED TO BE IN THE FALL OF 2020. THE WORK IS ANTICIPATED TO BE COMPLETED WITHIN 12 MONTHS AND TO CONCLUDE IN THE FALL OF 2021. EXIS77NG S17E CONDI AONS• THE AREA OF THE PROPOSED DEVELOPMENT IS VACANT LOT MOSTLY COVERED BY DENSE VEGETATION. THE SITE GENERALLY SLOPES FROM THE SOUTHEAST TO THE NORTHWEST TOWARDS STONEY RIDGE ROAD. ADJACENT AREAS: THIS SITE /S BORDERED TO THE NORTH, EAST AND WEST BY COMMERCIAL OFFICE BUILDINGS. TO THE SOUTH IS A DOG DAYCARE BUILDING AND A MEDICAL SERVICES BUILDINGS. SILT FENCE, DIVERSIONS, SEDIMENT TRAPS, INLET CONTROLS AND VARIOUS OTHER ESC MEASURES ARE PROPOSED TO LIMIT THE POTENTIAL FOR CONTAMINATION OF THESE ADJACENT PROPERTIES. OFFSITE LAND DISTURBANCE.• OFFSITE LAND DISTURBANCE IS LIMITED TO PUBLIC RIGHT-OF-WAY. SOILS: SEE SOIL DESCRIPTIONS ON THIS PAGE AND THE PHASE I EROSION & SEDIMENT CONTROL PLAN FOR SOIL BOUNDARIES. CRI77CAL AREAS.• THE MANAGED STEEP SLOPES ON THE EASTERN PORTION OF THE SITE ARE CONSIDERED TO BE CRITICAL. THE CONTRACTOR SHALL GIVE EXTRA ATTENTION AND CAUTION IN AND AROUND THESE AREAS TO ENSURE CONSTRUC77ON ACTIVITY DOES NOT DISTURB THESE EXIS77NG FEATURES. TREE PROTECT70N FENCING, SILT FENCING, DIVERSIONS AND SEDIMENT TRAPPING DEVICES SHALL ALSO BE INSTALLED AS A FIRST STEP IN LAND DISTURBANCE TO ENSURE THESE CRITICAL AREAS ARE MAINTAINED. SEQUENCE OF CONS77?UC770N: 1. CONTRACTOR SHALL NOTIFY THE ALBEMARLE COUNTY COMMUNITY DEVELOPMENT ENGINEERING DEPARTMENT TO SCHEDULE A PRE -CONSTRUCTION MEETING. 2. PRIOR TO DISTURBANCES, THE LIMITS OF DISTURBANCE SHALL BE FLAGGED AND THE TREE PROTECTION FENCING SHALL BE INSTALLED. J. NO EROSION CONTROL MEASURES MAY BE REMOVED DURING THE CONSTRUCTION PROCESS WITHOUT THE APPROVAL FROM THE INSPECTOR ON THE PROJECT. 4. INSTALLATION OF THE PROPOSED CONSTRUCT70N ENTRANCE SHALL OCCUR NEXT THE CONTRACTOR SHALL APPLY CONSTRUCTION ROAD STABILIZATION AS NEEDED. CONTRACTOR SHALL ENSURE THE CONSTRUCTION ENTRANCE DRAINS TO AN ADEQUATE E&S MEASURE. THE CONTRACTOR SHALL UTILIZE THE NEARBY SEDIMENT TRAP #1 FOR VEHICULAR WASH OFF. CONSTRUCTION ENTRANCE TO BE INSTALLED WHERE CONSTRUCTION VEHICLE ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTING TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. 5. THE INITIAL ESC CONSTRUCTION MEASURES, AS SHOWN ON THE PHASE I EROSION & SEDIMENT CONTROL PLAN, SHALL BE INSTALLED NEXT. THE CONTRACTOR SHALL BEGIN BY INSTALLING 7HE PERIMETER SILT FENCE AND TREE PROTECTION. PERIMETER MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 6. ONCE THE PERIMETER EROSION CONTROL MEASURES HAVE BEEN INSTALLED, AND THE COUNTY INSPECTOR HAS APPROVED THESE MEASURES, THE CONTRACTOR SHALL BEGIN LIGHT CLEARING. THE CONTRACTOR SHALL BEGIN BY CLEARING THE AREAS IN THE VICINITY OF SEDIMENT TRAP #1, AND THE AREAS REQUIRED TO ACCESS IT. FOLLOWING THIS MINOR CLEARING, THE CONTRACTOR SHALL INSTALL SEDIMENT TRAP #1 AND STRUCTURES 1-4, 9, 10 & A PORTION OF SIR. 5 TO THE NEAREST PIPE (OUTSIDE OF SEDIMENT TRAP #'1's FOOTPRINT). THE TIMING OF THESE STRUCTURES' CONSTRUCT70N WILL AVOID FUTURE DISTURBANCES TO THE TRAP IN SUBSEQUENT ESC PHASES. S7RUCTURES 4 & 5 SHALL BE SEALED WATERTIGHT TEMPORARILY UN77L THE TRAP IS CONVERTED TO A PERMANENT FACILITY. THIS WILL ALLOW STRUCTURE 10 TO CONTINUE TO DIVERT THE OFFSITE, UPLAND, CLEAN RUNOFF TO THE EXISTING STORM SEWER (TO REMAIN) WHEN THE ONSITE PORTION OF THE EXISTING CONCRETE DITCH IS REMOVED FOR THE INSTALLATION OF SEDIMENT TRAP #1. THIS SEQUENCING WILL HONOR THE EXISTING FLOW PATTERNS AND WILL PREVENT CLEAN WATER RUNOFF FROM BEING DISCHARGED DIRECTLY ONTO THE CONSTRUCTION SITE THE CONTRACTOR SHALL THEN INSTALL THE DIVERSIONS. ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE l EROSION CONTROL PLAN SHALL ALSO BE CONSTRUCTED AT THIS TIME. 7. ONCE ALL THE PHASE I EROSION CONTROL ITEMS HAVE BEEN INSTALLED & ARE OPERATIONAL DRAINAGE lS PROPERLY CONVEYED TO THE APPROPRIATE MEASURES, AND THE ESC INSPECTOR HAS GRANTED APPROVAL, THE CONTRACTOR CAN BEGIN CLEARING THE REMAINDER OF THE SITE. TEMPORARY SEEDING, PERMANENT SEEDING AND DUST CONTROL SHALL BE IMPLEMENTED AS REQUIRED. 8. AFTER CLEARING THE PROPOSED AREAS, THE CONTRACTOR CAN PROCEED TO PHASE III OF THE EROSION & SEDIMENT CONTROL PLAN. THE CONTRACTOR SHALL BEGIN ROUGH GRADING THE SITE TO THE CONTOURS SHOWN ON THE PHASE lI EROSION & SEDIMENT CONTROL PLAN. MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 9. THE CONTRACTOR SHALL INSTALL ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE ll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ll OF THE EROSION & SEDIMENT CONTROL PLAN. THE CONTRACTOR CAN BEGIN INSTALLATION OF THE UTILITIES CURB AND GUTTER AND ROADS. INLET PROTECTION SHALL ALSO INSTALLED AS THE STORM SEWER IS CONSTRUCTED. INLET PROTECTION SHALL BE INSPECTED AFTER EACH RAINFALL EVENT AND REPAIRS SHALL BE MADE AS NEEDED. IF THE STONE FILTER BECOMES CLOGGED WITH SEDIMENT SO THAT IT NO LONGER ADE UATELY PERFORMS ITS FUNCTION, , THE STONE MUST BE PULLED AWAY AND CLEANED AND/OR REPLACED. 12. ONCE PHASE III OF CONSTRUCT70N IS COMPLETE THE SITE IS STABILIZED AND THE INSPECTOR HAS GIVEN APPROVAL, THE CONTRACTOR CAN THEN CONVERT THE SEDIMENT TRAPS INTO THE PROPOSED SWM FACILITIES. AT THIS TIME, THE CONTRACTOR CAN REMOVE THE REMAINDER OF THE EROSION & SEDIMENT CONTROL MEASURES. NO ITEM SHALL BE REMOVED, THROUGHOUT ALL PHASES OF CONSTRUCTION, UNLESS THE UPSTREAM AREAS ARE STABILIZED AND THE INSPECTOR GIVES PERMISSION. 13. THE CONTRACTOR SHALL MAINTAIN ALL EROSION CONTROL MEASURES AS SPECIFIED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, REMOVING ONLY WHEN APPROVED BY THE LOCAL PROGRAM ADMINISTRATOR IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. 14. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL PROGRAM ADMINISTRATOR. TRAPPED SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND SEDIMENTATION.
