1. ALL CONSTRUCTION TRAFFIC SHALL UTILIZE THE CONSTRUCTION ENTRANCE AS DESIGNATED.
2. PRIOR TO COMMENCEMENT OF ANY LAND DISTURBING ACTIVITIES, ALL EROSION AND
SEDIMENTATION CONTROL MEASURES IDENTIFIED ON THIS PLAN SHALL BE INSTALLED IN
ACCORDANCE WITH THE EROSION CONTROL PLAN.
3. THE CONTRACTOR SHALL ENSURE THAT AREAS OUTSIDE OF THE LIMITS OF LAND
DISTURBANCE AS WELL AS TREES SPECIFICALLY NOTED FOR PROTECTION ARE NOT
ADVERSELY IMPACTED BY ANY CLEARING ACTIVITIES.
4. PRIOR TO FILLING THE SITE, THE CONTRACTOR SHALL STRIP AND STOCKPILE TOPSOIL IN
ACCORDANCE WITH GEOTECHNICAL REPORTS AT THE LOCATION INDICATED. AREAS WHICH ARE
TO BE FILLED SHALL BE RAISED IN COMPACTED SEQUENTIAL LIFTS NOT TO EXCEED 8
INCHES IN DEPTH. FILL MATERIAL SHALL BE CLEAN, WELL GRADED SAND. FILL LOCATED
BENEATH PAVEMENT SHALL BE COMPACTED PER GEOTECHNICAL REPORT. TOPSOIL
STOCKPILED CAN BE USED ON SITE FOR RESPREAD UPON COMPLETION OF FILL AND USED
WITHIN RAIN GARDEN AND LANDSCAPE BERM.
5. LIMITS OF SLOPES AND GRADING SHALL BE IN ACCORDANCE WITH THE LIMITS SHOWN
HEREON.
6. PROVIDE A GROUNDCOVER (TEMPORARY OR PERMANENT) ON EXPOSED SLOPES WITHING 21
CALENDAR DAYS FOLLOWING COMPLETION OF ANY PHASE OF GRADING; AND A PERMANENT
GROUNDCOVER FOR ALL DISTURBED AREAS WITHIN 15 WORKING DAYS OR 90 CALENDAR
DAYS (WHICHEVER IS SHORTER) FOLLOWING COMPLETION OF CONSTRUCTION OR
DEVELOPMENT.
7. IF ADDITIONAL MEASURES TO RESTRAIN EROSION BY WIND OR WATER ARE REQUIRED,
MEASURES SHALL BE INSTALLED AS DIRECTED BY THE ENGINEER OR DARE COUNTY.
8. SOIL EROSION AND SEDIMENTATION CONTROLS TO BE INSPECTED, MAINTAINED AND REPAIRED
AS NECESSARY.
9. EXISTING AND PROPOSED ELEVATIONS ARE BASED UPON NAVD 1988.

1. PRIOR TO CONSTRUCTION, THE CONTRACTOR SHALL CONTACT NC ONE CALL (800-632-4949) TO
LOCATE UNDERGROUND UTILITIES.
2. ALL STORM SEWERS SHALL BE PLACED IN ACCORDANCE WITH THE MANUFACTURER'S
RECOMMENDATIONS. STORM SEWERS SHALL BE SMOOTH INTERIOR, DOUBLE WALLED HDPE WITH
GASKETED CONNECTIONS UNLESS OTHERWISE NOTED.
3. CURB INLETS AND DRAINAGE STRUCTURES SHALL BE CONSTRUCTED PER NCDOT 840.
4. ALL OPEN PIPE ENDS SHALL BE FITTED WITH A FLARED END SECTION OF THE SAME MATERIAL
AND SIZE. END SECTIONS SHALL BE PROVIDED WITH RIP -RAP APRONS (SEE DETAILS).
5. INSTALLATION OF STORMWATER MANAGEMENT MEASURES SHALL BE IN ACCORDANCE WITH THIS PLAN
AND REQUIREMENTS STIPULATED BY THE DIVISION OF WATER QUALITY STORMWATER PERMIT.
6. IF RUNOFF FROM CONSTRUCTION ACTIVITIES IS DIRECTED TO THE STORMWATER BASIN, THE ENTIRE
BASIN BOTTOM SHALL BE TILLED/DISCED TO RESTORE INFILTRATION ABILITIES.
7. SEE SITE PLAN NOTES FOR AS -BUILT REQUIREMENTS. UPON COMPLETION OF THE WORK, THE
CONTRACTOR SHALL SUPPLY A CERTIFIED AS -BUILT SURVEY. THE SURVEY SHALL INCLUDE ALL
SITE IMPROVEMENTS AND STORMWATER MANAGEMENT FEATURES WITH ELEVATIONS.
1. UPON ACCEPTANCE BY THE OWNER, IT IS THE OWNER'S RESPONSIBILITY TO PROVIDE NECESSARY
MAINTENANCE SO THAT THE STORMWATER SYSTEM WILL FUNCTION AS INTENDED.
2. AFTER EVERY RUNOFF PRODUCING RAINFALL EVENT AND AT LEAST MONTHLY, INSPECT THE
INFILTRATION BASIN FOR EROSION, TRASH ACCUMULATION, VEGETATIVE COVER, AND GENERAL
CONDITION. ALSO INSPECT THE INFLOW STRUCTURES, OUTLET STRUCTURE, RIP -RAP AND BASIN
FOR OBSTRUCTION OR DETERIORATION. REMOVE ANY BLOCKAGE AND REPAIR THE STRUCTURE
TO APPROVED DESIGN SPECIFICATIONS
3. REPAIR ERODED AREAS IMMEDIATELY, RE -SEED AS NECESSARY TO MAINTAIN ADEQUATE
VEGETATIVE COVER, REMOVE TRASH AS NEEDED.
4. CHECK FOR SEDIMENTATION WITHIN THE BASIN ANNUALLY. IF DEPOSITION OF MATERIAL IS
OBSERVED WITHIN THE SYSTEM, REESTABLISH DESIGN GRADES AS INDICATED ON APPROVED SITE
PLAN.INSPECT BASIN WALLS AND STRUCTURES TO ENSURE THAT THEY ARE MAINTAINED AT THEIR
DESIGN ELEVATIONS. IF EROSION OCCURS, REESTABLISH DESIGN ELEVATIONS AS INDICATED ON
APPROVED SITE PLAN.
5. REFER TO STORMWATER MANAGEMENT INFILTRATION BASIN OPERATION AND MAINTENANCE
AGREEMENT FOR REQUIRED MAINTENANCE OF THE INFILTRATION BASIN.
