ADDITIONAL NOTES
1. ALL GENERAL NOTES, ABBREVIATIONS, SYMBOLS, AND OTHER INFORMATION INDICATED ON
COVER SHEET SHALL APPLY TO THIS PLAN
2. ALL ELEVATIONS SHOWN ARE IN REFERENCE TO THE BENCHMARK AND MUST BE VERIFIED BY
THE GENERAL CONTRACTOR WITH THE SURVEYOR OF RECORD PRIOR TO BEGINNING
CONSTRUCTION. TEMPORARY BENCHMARK IS AN EXISTING IRON ROD (EIR) LOCATED AT THE
NORTHWEST CORNER OF THE PROPERTY ON ELLIOT FARM ROAD (SR 1606) HAVING AN
ELEVATION OF 252.99'.
3. PURSUANT TO G.S.113A-57(2), THE ANGLE FOR GRADED SLOPES AND FILLS SHALL BE NO
GREATER THAN THE ANGLE THAT CAN BE RETAINED BY VEGETATIVE COVER OR OTHER
ADEQUATE EROSION CONTROL DEVICES OR STRUCTURES. IN ANY EVENT, SLOPES LEFT
EXPOSED WILL, WITHIN 14 CALENDAR DAYS OF COMPLETION OF ANY PHASE OF GRADING, BE
PLANTED OR OTHERWISE PROVIDED WITH TEMPORARY OR PERMANENT GROUND COVER,
DEVICES OR STRUCTURES SUFFICIENT TO RESTRAIN EROSION. PURSUANT TO G.S. 113A-57(3),
PROVISIONS FOR PERMANENT GROUND COVER SUFFICIENT TO RESTRAIN EROSION MUST BE
ACCOMPLISHED FOR ALL DISTURBED AREAS WITHIN 14 WORKING DAYS OR 90 CALENDAR
DAYS (WHICHEVER IS SHORTER) FOLLOWING COMPLETION OF CONSTRUCTION OR
DEVELOPMENT. ALL SEEDED AREAS WILL BE FERTILIZED, RE -SEEDED AS NECESSARY, AND
MULCHED ACCORDING TO SPECIFICATIONS IN THE VEGETATIVE PLAN TO MAINTAIN A
VIGOROUS, DENSE VEGETATION COVER. IF ANY SEEDING FAILURE OCCURS, THOSE AREAS
SHALL BE RE -SEEDED WITH RYE GRAIN FOR TEMPORARY STABILIZATION AND PREPARED FOR
PERMANENT SEEDING.
4. SEE DETAIL SHEETS FOR EROSION CONTROL MEASURES & MAINTENANCE.
5. CONTACT: DOHN BROADWELL, TEL. [phone]
6. CONTRACTOR SHALL REMOVE TEMPORARY EROSION CONTROL MEASURES ONLY AFTER
REMOVAL HAS BE APPROVED BY NCDENR.
7. CONTRACTOR SHALL BE RESPONSIBLE FOR PROVIDING EROSION AND SEDIMENTATION
CONTROL MONITORING ACCORDING TO NPDES PERMIT REQUIREMENTS.
8. SEE DETAIL SHEET FOR TEMPORARY & PERMANENT SEEDING REQUIREMENTS.
EROSION CONTROL CONSTRUCTION SEQUENCE
1. THIS SITE WAS PREVIOUSLY CLEARED AND GRUBBED UNDER NCDENR PROJECT NUMBER
CUMBE-2014-117, DATED 3-17-2014, AND LATER MODIFIED AND EXPANDED BY CUMBE 2020-020.
2. MAINTAIN ALL EXISTING EROSION CONTROL MEASURES INSTALLED UNDER NCDDEQ PROJECT
NUMBER CUMBE-2014-117 AND CUMBE 2020-020.
3. SEVERAL TEMPORARY SKIMMER BASINS WILL BE CONVERTED OR REMOVED AFTER A
STORMWATER DRYPOND HAS BEEN PARTIALLY CONSTRUCTED TO ACT AS A TEMPORARY
EROSION CONTROL DEVICE. DURING THE CONSTRUCTION PHASE, THESE DRYPONDS SHALL
BE ROUGH GRADED, STABILIZED AS PER THE TABLE BELOW, BAFFLES INSTALLED, WEIR WITH
MATTING INSTALLED, AND FAIRCLOTH SKIMMER INSTALLED. ONCE AUTHORIZED BY NCDEQ
AND THE ENGINEER, THESE PARTIALLY CONSTRUCTED WETLANDS SHALL BE COMPLETED BY
REMOVING BAFFLES, SKIMMER, AND SEDIMENT AND THEN COMPLETING FINE GRADING OF
SHALLOW WATER, SHALLOW LAND, DEEP POOLS, AND INSTALLING WETLAND PLANTS AND
OTHER REQUIREMENTS OF WETLAND PLANS AND DETAILS.
4. INSTALL ADDITION NEW EROSION CONTROL MEASURES SUCH AS INLET PROTECTION AND
DIVERSION BERMS.
5. APPLY TEMPORARY SEEDING TO ALL DISTURBED AREAS PER NPDES REQUIREMENTS. (SEE
TABLE THIS SHEET)
6. INSTALL INLET PROTECTION AS EACH STORM DRAIN INLET IS INSTALLED AND RIPRAP
DISSIPATORS AS THE FLARED END SECTIONS ARE INSTALLED.
7. CONSTRUCTION REQUIRING THE REMOVAL OF AN EXISTING CONTROL DEVICE SHALL ONLY BE
DONE WHEN THE UPSTREAM LAND AREA HAS BEEN STABILIZED.
8. CALL FOR INSPECTION BY ENGINEER AND NCDEQ.
9. TEMPORARY MEASURES SHALL REMAIN IN PLACE AND MAINTAINED UNTIL APPROVAL FOR
REMOVAL OF ALL TEMPORARY EROSION CONTROL MEASURES BY NCDEQ HAS BEEN
OBTAINED.
EXISTING PERMIT INFORMATION
SITE IS ACTIVELY PERMITTED FOR EROSION CONTROL UNDER PERMIT NUMBER CUMBE-2014-117.
PERMITTED DISTURBANCE OF 64.60 ACRES + CUMBE 2020-020 OF 4.06 ACRES = 67.66 TOTAL.
