CONSTRUCTING SILT FENCE, USE
LOCATION OF "LD/TP" LINE, AS "SF"
LINE IS OFFESET ONLY FOR
LEGIBILITY --ACTUAL LOCATION IS
AT "LD/TP" (TYP.)
CONSTRUCTION SEQUENCE:
1. OBTAIN LAND DISTURBANCE PERMIT FROM ORANGE COUNTY EROSION CONTROL
OFFICES AND APPROVED SET OF CONSTRUCTION DRAWINGS FROM THE
OWNER/ENGINEER. KEEP A COPY OF BOTH ITEMS ONSITE THROUGHOUT
CONSTRUCTION. CONTACT EROSION CONTROL OFFICER @ [phone] PRIOR
TO INITIATING LAND DISTURBING ACTIVITY.
2. SCHEDULE AND CONDUCT A PRE -CONSTRUCTION MEETING WITH ALL AGENCIES
AND NEIGHBORS AS REQUIRED BY PERMITS AND EROSION CONTROL OFFICER.
3. CLEAR ONLY AS NECESSARY TO INSTALL THE EROSION CONTROL DEVICES
SHOWN ON THIS PLAN.
4. THE STONE THAT WILL BE USED FOR THE DRIVEWAY WILL ALSO ACT AS THE
CONSTRUCTION ENTANCE/EXIT AND MAINTAIN PER THE NOTES ON THIS SHEET,
AND IN ACCORDANCE WITH ALL APPLICABLE LOCAL AND STATE GUIDELINES. ALL
CONSTRUCTION TRAFFIC IS TO ENTER AND EXIT THE PROPERTY FROM THIS
LOCATION.
5. EXERCISE EXTREME CAUTION NEAR ALL STREAM AND BUFFER AREAS TO ENSURE
DISTURBANCE RELATED TO CONSTRUCTION ACTIVITIES DOES NOT CONVEY
SEDIMENT LADEN RUNOFF INTO THE ADJACENT STREAM OR BUFFER. THE
CONTRACTOR SHALL MAKE EVERY EFFORT POSSIBLE TO PROMOTE AND
RE-ESTABLISH SHEET FLOW FROM THE DISTURBED AREAS FOR RUNOFF FLOWING
TO AND THROUGH THE ADJACENT BUFFERS.
6. TEMPORARILY SEED, MULCH, ANCHOR AND STABILIZE ALL DISTURBED AREAS AND
EROSION CONTROL DEVICES IMMEDIATELY AFTER CONSTRUCTION.
7. CONTINUE MAINTENANCE AND INSPECTION OF EROSION CONTROL DEVICES
AFTER RUNOFF PRODUCING STORM EVENTS. NO DISTURBED AREA IS TO BE LEFT
WITHOUT PROTECTIVE COVER (MULCH OR STRAW / TACK) FOR MORE THAN 15
WORKING DAYS OR 21 CALENDAR DAYS AFTER COMPLETION OF CONSTRUCTION
OR DEVELOPMENT ACTIVITIES.
8. COMPLETE FINAL SITE GRADING, THEN INSTALL PERMANENT SEEDING AND
PLANTINGS. ALL TEMPORARY AND PERMANENT STABILIZATION MEASURES SHALL
BE IN ACCORDANCE w/ THE MOST RECENT PLANTING AND SOIL PREPARATION
REQUIREMENTS ISSUED BY NCDENR.
9. ONCE SITE IS STABILIZE AND WITH THE APPROVAL OF THE EROSION CONTROL
OFFICER REMOVE ALL TEMPORARY EROSION CONTROL MEASURES, FINE GRADE,
PERMANENTLY SEED AND STABILIZE THESE AREAS AS NEEDED.

EROSION CONTROL & MAINTENANCE PLAN NOTES: MEASURES OR ADDITIONAL MEASURES WITHIN SEVEN DAYS. REPEATED FAILURE OF A CONTROL
MEASURE REQUIRES INSTALLATION OF A MORE SUITABLE DEVICE TO PREVENT DISCHARGED OF
POLLUTANTS FROM THE CONSTRUCTION SITE.
1. ALL EROSION CONTROL MEASURES SHALL BE CONSTRUCTED IN ACCORDANCE WITH THE
STANDARDS, SPECIFICATIONS AND DETAILS OF THE NC EROSION AND SEDIMENT CONTROL 5. INSTALLATION OF ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY THE
PLANNING AND DESIGN MANUAL AND BE APPROVED BY NORTH CAROLINA DEPARTMENT OF CITY/TOWN, COUNTY AND/OR STATE. CONTRACTOR TO VERIFY REQUIREMENTS PRIOR TO
ENVIRONMENTAL AND NATURAL RESOURCES AND/OR LOCAL AUTHORITIES PRIOR TO ANY AND BEGINNING ANY WORK ON PROJECT SITE.
ALL GRADING AND/OR CONSTRUCTION OF PROPOSED SITE. THE APPLICANT HAS THE
RESPONSIBILITY TO CONTACT, VERIFY AND ADHERE TO ALL NCDENR / LOCAL SPECIFICATIONS 6. CARE SHALL BE TAKEN TO MINIMIZE THE ENCROACHMENT OF SEDIMENT INTO ALL STORM DRAIN
AND CHECKLIST REQUIREMENTS, WHICH CAN BE REVIEWED AT THE NCDENR WEBSITE. APPURTENANCES, PUBLIC STREETS, AND ONTO PRIVATE PROPERTY UNTIL IMPERVIOUS
WWW.DLR.ENR.STATE.NC.US MATERIAL (ROAD/PARKING AREA SURFACE) IS APPLIED OR UNTIL PROPOSED LANDSCAPE HAS
BEEN ESTABLISHED.
2. RETAIN FLOATABLE WIND BLOWN MATERIALS ON SITE BY STORING ALL TRASH AND BUILDING
MATERIAL WASTE IN ENCLOSURES UNTIL DISPOSAL AT OFF -SITE FACILITIES. CHECK ADJACENT 7 REFER TO DETAILS ON THIS SHEET FOR SILT FENCE CONSTRUCTION.
AREAS DAILY AND PICK UP CONSTRUCTION WASTE MATERIALS AND DEBRIS THAT HAVE BLOWN
OR WASHED OFF SITE. 8. ALL AREAS NOT SHOWN AS PAVEMENT OR BUILDING UNDER FINAL CONSTRUCTION SHALL BE
TEMPORARILY AND PERMANENTLY SEEDED AS REQUIRED.
3. PERMANENTLY STABILIZE ALL SURFACE AREA WITHIN AND ADJACENT TO THIS SITE THAT IS
DISTURBED BY VEHICLES, GRADING AND OTHER CONSTRUCTION FOR THE PROPOSED FACILITY. 9 ALL GRASS SLOPES WHICH EXCEED 4:1 (H:V) SHALL UTILIZE NORTH AMERICAN GREEN (NAG)
STABILIZATION IS OBTAINED WHEN THE DISTURBED SURFACE IS COVERED WITH STRUCTURES, CONSTRUCTION PRODUCTS TURF REINFORCEMENT MATS SC150 OR APPROVED EQUAL UNLESS
PAVING AND OR PERENNIAL VEGETATION HAVING A UNIFORM COVERAGE DENSITY OF AT LEAST OTHERWISE SPECIFIED ON PLANS. MATS SHALL BE INSTALLED PER MANUFACTURER'S
70%. STABILIZATION OF ALL DISTURBED AREA IS REQUIRED BEFORE TERMINATION OF SPECIFICATIONS AND STANDARDS. CONTRACTOR SHALL COORDINATE INSTALLATION
MAINTENANCE AND REMOVAL OF EROSION CONTROL MEASURES. INSPECTION WITH MANUFACTURER.
4. CONTRACTORS SHALL INSPECT POLLUTION CONTROL MEASURES AT LEAST ONCE EVERY 15
DAYS AND WITHIN 24 HOURS AFTER A STORM EVENT OF 1/2 INCH OR GREATER. DAMAGED
MEASURES THAT PROVE TO BE INEFFECTIVE SHALL BE REPLACED WITH MORE EFFECTIVE

MAINTENANCE:
INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND

IMMEDIATELY. SHOULD THE FABRIC OF A FENCE COLLAPSE,
TEAR, DECOMPOSE OR BECOME INEFFECTIVE, REPLACE IT
PROMPTLY. REPLACE BURLAP EVERY 60 DAYS. REMOVE
SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE ADEQUATE
STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESSURE ON THE FENCE.TAKE CARE TO AVOID
UNDERMINING THE FENCE DURING CLEANOUT. REMOVE ALL
FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND
BRING THE ARE TO GRADE AND STABILIZE IT AFTER THE
