EROSION CONTROL NOTES:
1.
ALL EROSION CONTROL MEASURES SHALL BE IN ACCORDANCE WITH THE NC EROSION AND SEDIMENT CONTROL PLANNING AND
DESIGN MANUAL, US DEPT. OF AGRICULTURE, AND THE SCS. THE CONTRACTOR SHALL DILIGENTLY AND CONTINUOUSLY
MAINTAIN ALL EROSION CONTROL DEVICES AND STRUCTURES TO MINIMIZE EROSION.
2.
ALL LAND OWNERS MUST BE NOTIFIED PRIOR TO CONSTRUCTION, AND ALL EASEMENTS MUST BE CURRENT.
3.
CONTRACTOR IS RESPONSIBLE FOR STOPPING SEDIMENTATION DOWNGRADE OF ALL DISTURBED AREAS. SILT FENCE SHOWN
ON THIS PLAN IS THE MINIMUM THAT SHALL BE INSTALLED. CONTRACTOR SHALL INSTALL ADDITIONAL SILT FENCE WHEREVER
FIELD CONDITIONS WILL RESULT IN SEDIMENTATION OF NON -DISTURBED AREAS.
SOILS PRESENT ON -SITE ARE: Bb, CeB, GeB, McB, PaD, Wt.
4.
TOTAL DENUDED AREA = 28.0 AC.
5.
ANY GRADING BEYOND THE DENUDED LIMITS SHOWN ON THE PLAN IS A VIOLATION OF THE STATE/COUNTY EROSION CONTROL
ORDINANCE AND IS SUBJECT TO A FINE.
6.
ADDITIONAL MEASURES TO CONTROL EROSION AND SEDIMENT MAY BE REQUIRED BY A REPRESENTATIVE OF THE
INSPECTORS/COUNTY/STATE.
7.
ALL DISTURBED AREAS MUST BE STABILIZED WITHIN 14 CALENDAR DAYS AND ALL DISTURBED PERIMETER AREAS WITHIN 7
CALENDAR DAYS AFTER LAND DISTURBING ACTIVITY IS COMPLETED OR HAS TEMPORARILY CEASED.
8.
ALL GRADED SLOPES AND FILLS MUST BE STABILIZED WITHIN 14 CALENDAR DAYS AND GRADED SLOPES AND FILLS WITH A
SLOPE GREATER THAN 3:1 WITHIN 7 CALENDAR DAYS AFTER A PHASE OF GRADING IS COMPLETED OR HAS TEMPORARILY
CEASED.
9.
GRADING MORE THAN ONE ACRE WITHOUT AN APPROVED EROSION CONTROL PLAN IS A VIOLATION OF THE COUNTY/STATE
EROSION CONTROL ORDINANCE AND IS SUBJECT TO A FINE.
10.
CONTRACTOR SHALL MAINTAIN ALL EROSION CONTROL DEVICES AND STRUCTURES REQUIRED PER THE APPROVED EROSION
CONTROL PLANS THROUGHOUT THE LIFE CYCLE OF THE PROJECT. THIS MAY INCLUDE: CONSTRUCTION ENTRANCE, SILT FENCE,
DIVERSION DITCHES, SEDIMENT BASIN AND TRAPS, SILT FENCE BAFFLES, AND TREE PROTECTION FENCE.
11.
INSPECTIONS SHALL BE CONDUCTED AS PRESCRIBED BYJOHNSTON COUNTY. ADDITIONAL INSPECTIONS MAY BE CONDUCTED
ON ANY REASONABLE BASIS, INCLUDING BUT NOT LIMITED TO: RANDOM INSPECTIONS; INSPECTIONS BASED UPON
COMPLAINTS OR OTHER NOTICE OF POSSIBLE VIOLATIONS; INSPECTIONS OF DRAINAGE BASINS OR AREAS IDENTIFIED AS
HIGHER THAN TYPICAL SOURCES OF SEDIMENT OR OTHER CONTAMINANTS OR POLLUTANTS; INSPECTIONS OF BUSINESSES OR
INDUSTRIES OF A TYPE ASSOCIATED WITH HIGHER THAN USUAL DISCHARGERS OF CONTAMINANTS OR POLLUTANTS OR WITH
DISCHARGES OF A TYPE WHICH ARE MORE LIKELY THAN THE TYPICAL DISCHARGE TO CAUSE VIOLATIONS OF STATE OR
FEDERAL WATER QUALITY STANDARDS OR THE NPDES STORMWATER PERMIT; AND JOINT INSPECTIONS WITH OTHER AGENCIES
INSPECTING UNDER ENVIRONMENTAL AND SAFETY LAWS. INSPECTIONS MAY INCLUDE BUT ARE NOT LIMITED TO: REVIEWING
MAINTENANCE AND REPAIR RECORDS; SAMPLING DISCHARGES, SURFACE WATER, GROUNDWATER, AND MATERIAL OR WATER IN
BMPS; EVALUATING THE CONDITION OF BMPS AND STORMWATER MANAGEMENT PRACTICES.
12.
RIGHT -OF -ENTRY FOR INSPECTION. THE PROPERTY OWNER SHALL GRANT TO JOHNSTON COUNTY ENVIRONMENTAL
MANAGEMENT OR ANY OTHER GOVERNING AGENCY, THE RIGHT TO ENTER THE PROPERTY AT REASONABLE TIMES AND IN A
REASONABLE MANNER FOR THE PURPOSE OF INSPECTION.
13.
IF NECESSARY, SLOPES, WHICH EXCEED EIGHT (8) VERTICAL FEET SHOULD BE STABILIZED WITH SYNTHETIC OR VEGETATIVE
MATS, IN ADDITION TO HYDROSEEDING. IT MAY BE NECESSARY TO INSTALL TEMPORARY SLOPE DRAINS DURING
CONSTRUCTION. TEMPORARY BERMS MAY BE NEEDED UNTIL THE SLOPE IS BROUGHT TO GRADE.
14.
THE CONTRACTOR MUST TAKE NECESSARY ACTION TO MINIMIZE THE TRACKING OF MUD ONTO PAVED ROADWAY(S) FROM
CONSTRUCTION AREAS AND THE GENERATION OF DUST. THE CONTRACTOR SHALL DAILY REMOVE MUD/SOIL FROM PAVEMENT,
AS MAY BE REQUIRED.
15.
ALL WATERS OF THE STATE (WOS), INCLUDING WETLANDS, ARE TO BE FLAGGED OR OTHERWISE CLEARLY MARKED IN THE
FIELD. A DOUBLE ROW OF SILT FENCE IS TO BE INSTALLED IN ALL AREAS WHERE A 50-FOOT BUFFER CAN'T BE MAINTAINED
BETWEEN THE DISTURBED AREA AND ALL WOS. A 10-FOOT BUFFER SHOULD BE MAINTAINED BETWEEN THE LAST ROW OF SILT
FENCE AND ALL WATERS OF THE STATE.
SOIL STOCKPILE NOTES:
1.
A 25-FOOT TEMPORARY MAINTENANCE AND ACCESS EASEMENT SHALL BE SHOWN AROUND ALL PROPOSED STOCKPILES
(EROSION CONTROL MEASURES SURROUNDING THE STOCKPILE SHALL BE SHOWN AT THE OUTER LIMIT OF THIS EASEMENT).
2.
STOCKPILE FOOTPRINTS SHALL BE SETBACK A MINIMUM OF 25' FROM ADJACENT PROPERTY LINES.
3.
STOCKPILE HEIGHT SHALL NOT EXCEED 35 FEET.
4.
STOCKPILE SLOPES SHALL BE 2:1 OR FLATTER.
5.
APPROVED BMPS SHALL BE SHOWN ON A PLAN TO CONTROL ANY POTENTIAL SEDIMENT LOSS FROM A STOCKPILE.
6.
STOCKPILING MATERIALS ADJACENT TO A DITCH, DRAINAGEWAY, WATERCOURSE, WETLAND, STREAM BUFFER, OR OTHER
BODY OF WATER SHALL BE AVOIDED UNLESS ALTERNATIVE LOCATION IS DEMONSTRATED TO BE UNAVAILABLE.
7.
ANY CONCENTRATED FLOW LIKELY TO AFFECT THE STOCKPILE SHALL BE DIVERTED TO AN APPROVED EROSION CONTROL
FACILITY.
8.
OFF -SITE SPOIL OR BORROW AREAS MUST BE IN COMPLIANCE WITH JOHNSTON COUNTY LIDO AND STATE REGULATIONS. ALL
SPOIL AREAS OVER AN ACRE ARE REQUIRED TO HAVE AN APPROVED SEDIMENT CONTROL PLAN. DEVELOPER/ CONTRACTOR
SHALL NOTIFY JOHNSTON COUNTY OF ANY OFFSITE DISPOSAL OF SOIL, PRIOR TO DISPOSAL. FILL OF FEMA FLOODWAYS
AND NON -ENCROACHMENT AREAS ARE PROHIBITED.
STOCKPILE MAINTENANCE REQUIREMENTS:
1.
SEEDING OR COVERING STOCKPILES WITH TARPS OR MULCH IS REQUIRED AND WILL REDUCE EROSION PROBLEMS. TARPS
SHOULD BE KEYED IN AT THE TIP OF THE SLOPE TO KEEP WATER FROM RUNNING UNDERNEATH THE PLASTIC.
2.
IF A STOCKPILE IS TO REMAIN FOR FUTURE USE AFTER THE PROJECT IS COMPLETE (BUILDERS, ETC.), THE FINANCIAL
RESPONSIBLE PARTY MUST NOTIFY JOHNSTON COUNTY OF A NEW RESPONSIBLE PARTY FOR THAT STOCKPILE.
3.
THE APPROVED PLAN SHALL PROVIDE FOR THE USE OF STAGED SEEDING AND MULCHING ON A CONTINUAL BASIS WHILE THE
STOCKPILE IS IN USE.
4.
ESTABLISH AND MAINTAIN A VEGETATIVE BUFFER AT THE TOE OF THE SLOPE (WHERE PRACTICAL).
5.
SEE SHEET EC3.1 FOR SEEDBED PREPARATION, TIMETRAMES, MIXTURE AND SCHEDULING.
STREAM CROSSING SEQUENCE:
1.
OBTAIN NECESSARY PERMITS FOR STREAM AND BUFFER DISTURBANCE. LIMITS OF DISTURBANCE SHALL NOT EXCEED
THOSE SHOWN ON APPROVED PERMITS PLANS.
2.
INSTALLATION OF STREAM CROSSING SHOULD BE SCHEDULED DURING A TIME WHEN HEAVY RAINS AREN'T ANTICIPATED.
CONSTRUCTION MUST OCCUR "IN THE DRY".
3.
SET UP BYPASS PUMP AND TEMPORARY PIPING. PLACE OUTLET OF TEMPORARY PIPE TO MINIMIZE EROSION AT DISCHARGE
SITE OR PROVIDE TEMPORARY ENERGY DISSIPATION MEASURES. FIRMLY ANCHOR PUMP AND PIPING.
4.
CONSTRUCT IMPERVIOUS DIKE UPSTREAM OF WORK AREA TO IMPOUND WATER FOR BYPASS PUMP INTAKE. USE A
FLOATING INTAKE FOR PUMPS WHERE POSSIBLE.
5.
CONSTRUCT AN IMPERVIOUS DIKE DOWNSTREAM OF WORK AREA, IF POSSIBLE, TO ISOLATE WORK AREA.
6.
CHECK OPERATION OF PUMP AND PIPING SYSTEM.
7.
INSTALL TEMPORARY 24" SLOPE DRAIN PIPE IN ACCORDANCE WITH THE APPROVED PLAN
8.
UPON COMPLETION OF CONSTRUCTION, REMOVE IMPERVIOUS DIKE(S), BYPASS PUMP AND TEMPORARY PIPE.
*ROUTINELY
INSPECT BYPASS PUMP AND TEMPORARY PIPING TO ENSURE PROPER OPERATION.
*INSPECT IMPERVIOUS DIKE(S) FOR LEAKS AND REPAIR ANY DAMAGE.
*INSPECT DISCHARGE POINT FOR EROSION.
*ENSURE FLOW IS ADEQUATELY DIVERTED THROUGH PIPE.
