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 STORMWATER TREATMENT AREA.
5. LIMITS OF SLOPES AND GRADING SHALL BE IN ACCORDANCE WITH THE LIMITS SHOWN
HEREON.
6. CLEAN EXCESS MATERIAL MAY BE USED TO MOUND INTERIOR LANDSCAPE ISLANDS (12"
MAX., 4:1 SLOPE)
DRAMACiE W7M
1. PRIOR TO CONSTRUCTION, THE CONTRACTOR SHALL CONTACT INC ONE CALL (800-632-4949)
TO LOCATE UNDERGROUND UTILITIES.
2. ALL STORM SEWERS AND CULVERTS SHALL BE ADS N-12 (WT-1B OR HP) UNLESS NOTED
OTHERWISE.
3. DROP INLETS AND DRAINAGE STRUCTURES SHALL BE CONSTRUCTED PER NCDOT 840.
4. INSTALLATION OF STORMWATER MANAGEMENT MEASURES SHALL BE IN ACCORDANCE WITH THIS
PLAN AND REQUIREMENTS STIPULATED BY THE DIVISION OF WATER QUALITY STORMWATER PERMIT.
5. 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.
S7DWWA7M M4MGSWffC MAMHVANCE NOTES
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
STORMWATER MANAGEMENT POND 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.
