EROSION & SEDIMENT CONTROL NARRATIVE: EROSION AND SEDIMENT CONTROL MEASURES: MAINTENANCE:
PROJECT DESCRIPTION:
THIS PROJECT CONSISTS OF THE CONSTRUCTION OF A SINGLE FAMILY RESIDENCE AND ASSOCIATED ACCESS. THE DISTURBANCE AREA ASSOCIATED WITH
THIS PROJECT IS t3.23 AC (140,676 SF). IT IS ANTICIPATED THAT THE WORK WILL START IN FEBRUARY AND LAST 12 MONTHS.
EXISTING SITE CONDITIONS:
THE SITE CONSISTS OF VACANT WOODED LAND BORDERED TO THE REAR BY STOCKTON MILL CREEK. THE SLOPES WITHIN THE PROJECT AREA RANGE
FROM 3 TO 30 PERCENT.
ADJACENT AREAS:
THE PROPOSED PROJECT IS BORDERED BY SINGLE FAMILY RESIDENCES ON ALL SIDES, BY STOCKTON MILL CREEK TO THE NORTH, AND BY BATESVILLE
ROAD TO THE SOUTH.
OFF -SITE AREAS:
IT IS NOT ANTICIPATED THAT ANY OFF -SITE AREAS WILL BE DISTURBED DURING CONSTRUCTION. UNSUITABLE MATERIALS RESULTING FROM THE
PROPOSED WORK SHALL BE HAULED FROM THE SITE AND DISPOSED OF AT AN APPROVED DISPOSAL SITE PERMITTED SEPARATELY FROM THIS PROJECT.
SOILS:
SEE THE USDA SOILS DELINEATION MAP SHEET C1.0.
CRITICAL AREAS:
THIS SITE HAS NO CRITICAL AREAS IN THE IMMEDIATE VICINITY OF THE PROPOSED CONSTRUCTION. HOWEVER, PROPER EROSION CONTROL MEASURES AS
SHOWN ON THE PLANS SHALL BE PUT IN PLACE TO PREVENT SILT FROM LEAVING THE PROJECT AREA AND ENTERING THE STREAM BUFFER DOWNHILL.
EROSION & SEDIMENT CONTROL MEASURES:
REFER TO THIS SHEET FOR A LIST OF ALL PROPOSED EROSION AND SEDIMENT CONTROL MEASURES TO BE USED ON SITE.
PERMANENT STABILIZATION:
THE SITE WILL BE STABILIZED THROUGH THE USE OF PERMANENT SEEDING, STONE AND RIPRAP, LANDSCAPING, AND PAVEMENT. SEEDING INFORMATION,
DATES AND AMENDMENTS ARE INCLUDED ON THE PLANS. SOIL TESTING SHALL BE COMPLETED THE CONTRACTOR TO DETERMINE THE SUITABILITY OF
EXISTING SOILS AND THE NEED FOR ANY SOIL AMENDMENTS TO ENSURE THAT PERMANENT SEEDING WILL GROW EFFECTIVELY.
STORM WATER RUNOFF CONSIDERATIONS:
STORMWATER RUNOFF DURING CONSTRUCTION WILL BE DIRECTED THROUGH APPROPRIATE EROSION AND SEDIMENT CONTROLS TO CLEAN WATER
BEFORE DISCHARGING TO AN ADEQUATE OUTFALL PROTECTED FROM EROSION AND SEDIMENT AS SHOWN ON THE PLANS.
MAINTENANCE:
ALL E&S MEASURES SHALL BE INSPECTED REGULARLY AS REQUIRED BY STATE STANDARDS AND MAINTAINED IN GOOD WORKING ORDER. REQUIRED
REPAIRS SHALL BE MADE IMMEDIATELY. SEE THE MAINTENANCE NARRATIVE ON THIS SHEET FOR SPECIFIC MAINTENANCE ITEMS AND INSPECTION TIMES.
ALBEMARLE COUNTY EROSION & SEDIMENT CONTROL NOTES:
General construction notes for Erosion and Sediment Control plans

minimum standards and specifications of the Virginia Erosion and Sediment Control
Handbook and Virginia Regulations VR 625-02-00 Erosion and Sediment Control
Regulations.
3. All erosion and sediment control measures are to be placed prior to or as the fast step in

4. A copy of the approved erosion and sediment control plan shall be maintained on the site at
all times.
5. Prior to commencing land disturbing activities in areas other than indicated on these plans
(including, but not limited to, off -site borrow or waste areas), the contractor shall submit a
supplementary erosion control plan to the owner for review and approval by the plan
approving authority.
6. The contractor is responsible for installation of any additional erosion control measures
necessary to prevent erosion and sedimentation as determined by the plan approving
authority.

land disturbing activities and during site development until final stabilization is achieved.
8. During dewatering operations, water will be pumped into an approved filtering device.
9. The contractor shall inspect all erosion control measures periodically and after each runoff -
producing rainfall event. Any necessary repairs or cleanup to maintain the effectiveness of
the erosion control devices shall be made immediately.
10. All fill material to be taken from an approved, designated borrow area.

IN GENERAL, ALL EROSION AND SEDIMENTATION CONTROL MEASURES SHALL BE CHECKED DAILY AND AFTER EACH RAINFALL EVENT GREATER THAN 0.25
INCHES. MEASURES SHOULD BE CLEANED AND REPAIRED ACCORDING TO THE FOLLOWING SCHEDULE AND THE VIRGINIA EROSION AND SEDIMENT CONTROL
HANDBOOK. THE FOLLOWING WILL BE CHECKED IN PARTICULAR:
1. THE CONSTRUCTION ENTRANCES AND CONSTRUCTION ROAD STABILIZATION AREAS SHALL BE MAINTAINED IN A CONDITION WHICH WILL PREVENT
TRACKING OR FLOW OF MUD ONTO PUBLIC RIGHTS -OF -WAY THROUGH PERIODIC TOP DRESSING WITH ADDITIONAL STONE AND/OR WASHING AND
REWORKING OF EXISTING STONE.
2. SEDIMENT DEPOSITS SHALL BE REMOVED FROM SILT FENCE AFTER EACH RAINFALL. UNDER NO CIRCUMSTANCES SHALL DEPOSITS BE ALLOWED TO
ACCUMULATE ABOVE HALF THE HEIGHT OF THE FENCE. DAMAGED OR UNDERCUT SILT FENCE SHALL BE REPAIRED IMMEDIATELY. SHOULD SILT FENCE
BECOME INEFFECTIVE OR REACH THE END OF THE EXPECTED USEABLE LIFE, FABRIC SHALL BE REPLACED IMMEDIATELY. UPON SILT FENCE REMOVAL,
DRESS ANY SEDIMENT DEPOSITS TO CONFORM WITH EXISTING GRADE AND SEED.
3. INLET PROTECTION SHALL BE CHECKED REGULARLY FOR SEDIMENT. IF EXCESSIVE SEDIMENT IS PRESENT, OR IF EXCESSIVE PONDING OCCURS AFTER
RAINFALL, THE STONE SHALL BE PULLED AWAY AND CLEANED OR REPLACED.
4. STONE USED IN CULVERT INLET PROTECTION SHALL BE INSPECTED REGULARLY FOR CLOGGING AND REPLACED AS NEEDED TO MAINTAIN FULL
FUNCTIONALITY. UNDER NO CIRCUMSTANCES SHALL SEDIMENT BE ALLOWED TO ACCUMULATE ABOVE ONE-HALF OF THE HEIGHT OF THE INLET
PROTECTION. ACCUMULATED SEDIMENT SHALL BE REMOVED AND UPSTREAM AREAS PERMANENTLY STABILIZED BEFORE THIS CONTROL IS REMOVED.
5. CHECK DAMS SHALL BE INSPECTED REGULARLY TO ENSURE THE CENTER OF THE DAM IS LOWER THAN THE EDGES. SEDIMENT SHALL BE REMOVED
WHEN IT REACHES ONE HALF THE HEIGHT OF THE DAM.
6. ANY SOIL WITHIN TREE PROTECTION AREAS THAT IS INADVERTENTLY COMPACTED SHALL BE AERATED WITH AN IRON BAR EVERY 18 INCHES TO A DEPTH
OF 12 INCHES. PHYSICAL DAMAGE TO TREES SHALL BE REPAIRED AS OUTLINED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK SECTION
3.38. TREES THAT ARE STRESSED OR DAMAGED SHALL RECEIVE AN APPROPRIATE APPLICATION OF FERTILIZER TO AID RECOVERY.
7. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO SEE THAT A GOOD STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS
NEEDED.
8. ALL TEMPORARY EROSION AND SEDIMENT MEASURES SHALL BE DISPOSED OF WITHIN THIRTY (30) DAYS AFTER FINAL SITE STABILIZATION IS ACHIEVED
AND VEGETATION IS ESTABLISHED. FINAL SITE STABILIZATION SHALL BE APPROVED BY THE OWNER AFTER THE INSPECTOR HAS DETERMINED THAT THE
SITE IS STABILIZED.
MANAGEMENT STRATEGIES:
THE FOLLOWING SEQUENCE OF EVENTS AND EROSION CONTROL MEASURES SHALL BE INCORPORATED INTO THE CONSTRUCTION SCHEDULE FOR THIS
PROJECT AND SHALL APPLY TO ALL CONSTRUCTION ACTIVITIES WITHIN PROJECT LIMITS.
1. CONSTRUCTION WILL BE SEQUENCED SO THAT TRENCHING AND EXCAVATION OPERATIONS CAN BEGIN AND END AS QUICKLY AS POSSIBLE.

13. REPAIR ANY EROSION AND REMOVE ANY SEDIMENT.
15. DRESS AND OVER -SEED ALL DISTURBED AREAS AS NECESSARY TO AFFECT PERMANENT VEGETATIVE COVER. STABILIZE ALL REMAINING DISTURBED AREAS
WITH TOPSOIL, SEED, AND MULCH ONCE WORK IS COMPLETE.
16. REMOVE SEDIMENT TRAP AND ASSOCIATED DIVERSION DIKES ONCE PERMANENT VEGETATIVE COVER HAS BEEN ESTABLISHED ON SITE.
17. BEGIN INSTALLATION OF ANY PROPOSED BMPS ONCE ALL CONTRIBUTING AREAS ARE STABILIZED AND FREE OF DEBRIS. REFER TO INSTALLATION CHECKLIST
AND INSPECTION MILESTONES FOR CONSTRUCTION MILESTONES. INSTALL PERMANENT CONVEYANCE CHANNELS TO BMPS AT THIS TIME, STABILIZING
IMMEDIATELY WITH EC-2 TYPE 1 MATTING.
18. AFTER FINAL SITE STABILIZATION AND APPROVAL FROM THE APPROPRIATE EROSION AND SEDIMENT CONTROL AUTHORITY, THE SILT FENCE, INLET PROTECTION

EXISTING DRAINAGE PATTERNS ARE LARGELY PRESERVED, WITH ALL MAJOR DRAINAGE AREAS RELEASED AS SHEET FLOW FROM THE
SITE. IN POST -DEVELOPMENT CONDITIONS, LEVEL SPREADERS ARE LOCATED AT ALL CONCENTRATED OUTFALLS TO RETURN APPROVED DCH
CHANNELIZED WATER FROM THE SITE TO SHEET FLOW TO CONFORM WITH 9VAC25-870-66(D). SINCE NO ALTERNATIVE FLOWPATH
Ix SUBMSSInni ni 2
EXISTS FOR STORMS LARGER THAN THE WATER QUALITY DESIGN STORM, THE LEVEL SPREADERS HAVE BEEN DESIGNED USING PEAK
/ FLOWS FROM THE 10-YEAR DESIGN STORM. THIS ENSURES THAT 9VAC25-870-66(D) APPLIES FOR THE 10-YEAR DESIGN STORM. AT
PROJECT 2107007
INDIVIDUAL DOWNSPOUTS NOT DIRECTED TO AN ENGINEERED LEVEL SPREADER, FLOW WILL BE DISSAPATED WITH CUSTOM, LARGE

THIS ENSURES ALBEMARLE COUNTY'S STORMWATER MANAGEMENT T H E W 0 R h r
SINCE THE EXISTING GRADES DOWNHILL OF THE LEVEL SPREADERS RANGE FROM 15%25%, PARTICULAR CARE HAS BEEN TAKEN IN
THE DESIGN OF THE SPREADERS. DOWNHILL ALLOWABLE VELOCITIES HAVE BEEN DETERMINED, AND LEVEL SPREADERS HAVE BEEN
DESIGNED SUCH THAT THE VELOCITY OVER THE WEIR IS LESS THAN 33/o OF THE ALLOWABLE VELOCITY. THIS ENSURES THAT, AS
RUNOFF RECONCENTRATES DOWNHILL, ALLOWABLE VELOCITIES ARE NOT EXCEEDED. IN ADDITION, A CONSERVATIVE RAINFALL C5mO
