PROCEDURES AND REQUIREMENTS
THE STORMWATER CONTROL MEASURE IS INTENDED TO MAINTAIN THE WATER ELEVATION AT THE NORMAL POOL ELEVATION INDEFINITELY ASSUMING NO EVAPORATION. BASED ON THE EXISTING SOILS, AND
THE LEVEL OF THE SEASONALLY HIGH WATER TABLE, A LINER MAY BE REQUIRED TO ENSURE THE ACTUAL RATE OF DROP OF THE WATER SURFACE IS LESS THAN 0.24 INCHES PER DAY, NOT INCLUDING
EVAPOTRANSPIRATION.
IT IS THE CONTRACTOR'S RESPONSIBILITY, IN CONSULTATION WITH THE PROJECT GEOTECHNICAL ENGINEER OR THE CONTRACTOR'S GEOTECHNICAL ENGINEER, TO DETERMINE IF A LINER IS NEEDED PRIOR TO
CONVERTING THE STORMWATER CONTROL MEASURE FROM A TEMPORARY EROSION CONTROL MEASURE TO A PERMANENT STORMWATER CONTROL MEASURE.
IF A CLAY LINER IS USED, PRIOR TO PLACEMENT, THE CONTRACTOR IS RESPONSIBLE FOR HAVING THE PROJECT GEOTECHNICAL ENGINEER TEST THE LINER MATERIAL PERMEABILITY, DEVELOP ANY SPECIAL
CONDITIONS OF THE INSTALLATION SUCH AS PLACING THE LINER MATERIAL ON THE WET SIDE OF OPTIMUM MOISTURE CONTENT, AND CONFIRMING THAT THE EXPECTED POND INFILTRATION RATE WITH THE
PROPOSED CLAY LINER WILL REDUCE SEEPAGE LOSS RATES TO THE PROJECT REQUIREMENTS. FOLLOWING INSTALLATION THE CLAY LINER THICKNESS IS TO BE CHECKED AT RANDOM LOCATION BY THE PROJECT
GEOTECHNICAL ENGINEER TO VERIFY COMPLIANCE. IF A SYNTHETIC LINER IS USED, A QUALIFIED LINER DESIGNER SHALL BE CONSULTED. THE MANUFACTURER'S INSTALLATION INSTRUCTIONS SHALL BE REVIEWED
BY THE CONTRACTOR, THE LINER DESIGNER, AND THE PROJECT GEOTECHNICAL ENGINEER PRIOR TO INSTALLATION TO DETERMINE IF ADDITIONAL MEASURES ARE NECESSARY BASED ON LOCAL SITE CONDITIONS.
IN NO CASE SHALL THE DEPTH OF SOIL OVER THE LINER BE LESS THAN 12 INCHES IN ORDER TO PROTECT THE LINER FROM DAMAGE. THE DEPTH OF SOIL COVER OVER THE LINER SHALL BE CHECKED AT RANDOM
LOCATIONS BY THE PROJECT GEOTECHNICAL ENGINEER TO VERIFY COMPLIANCE. THE CONTRACTOR SHALL WARN THE LANDSCAPING SUBCONTRACTOR ABOUT THE PRESENCE OF THE LINER. THE LANDSCAPING
SUBCONTRACTOR SHALL TAKE CARE IN THE INSTALLATION OF THE PLANTING NOT TO DAMAGE THE LINER. PRIOR TO INSTALLATION OF THE REQUIRED PLANT MATERIAL, THE VALVE FROM THE WETLAND BASIN
SHALL BE CLOSED, THE POND FILLED, AND THE ABILITY TO HOLD WATER PER THE PROJECT REQUIREMENTS CONFIRMED. THIS TEST SHALL BE REPEATED AFTER THE INSTALLATION OF THE PLANT MATERIAL.
REGARDLESS OF THE CARE TAKEN DURING INSTALLATION AND THE TESTING AND SUPPORTING DOCUMENTATION OF THE PROJECT GEOTECHNICAL ENGINEER, IF THE LOSS RATE FROM THE POND EXCEEDS THE
PROJECT REQUIREMENTS, THE CONTRACTOR IS RESPONSIBLE FOR REDUCING THAT RATE TO THE PROJECT REQUIREMENTS BY MEANS THAT STILL PROVIDE ACCEPTABLE WATER QUALITY AND CONDITIONS
APPROPRIATE FOR PLANT GROWTH, AT HIS COST. THE CONTRACTOR IS RESPONSIBLE FOR QUALITY CONTROL TESTING DURING CONSTRUCTION TO VERIFY THE LINER, CLAY OR SYNTHETIC, IS INSTALLED IN
ACCORDANCE WITH THE PLANS, RECOMMENDATIONS OF THE GEOTECHNICAL ENGINEER, AND MANUFACTURER'S INSTRUCTIONS. A REPORT OF THE INSTALLATION AND AS BUILT CONDITIONS SHALL BE PROVIDED
TO THE OWNER BY THE CONTRACTOR'S PROJECT GEOTECHNICAL ENGINEER AFTER CONSTRUCTION. IF FOR ANY REASON THE LOSS RATE EXCEEDS THE PROJECT STANDARD, THE CONTRACTOR SHALL BE
RESPONSIBLE FOR PROVIDING REMEDIAL MEASURES, UNDER THE SUPERVISION OF A QUALIFIED GEOTECHNICAL ENGINEER, TO BRING THE LOSS RATE INTO COMPLIANCE WITH THE ABOVE STANDARD.

INSTALLATION ACCORDINGLY.
7. ONCE THE PLANTINGS HAVE BEEN DELIVERED TO THE SITE FROM THE NURSERY THEY SHOULD BE FREQUENTLY WATERED,
FERTILIZED AND SHADED UNTIL THEY ARE INSTALLED.
5. ALL DISTURBED AREAS AROUND THE OUTSIDE OF THE WET POND SHALL BE SEEDED WITH A LAWN AREA SEED MIX (PER
SEEDING SPECIFICATIONS) NATIVE GRASSES, LEGUMES, CLOVERS AND WILDFLOWERS.
q. PLANTING AREAS SHOWN IN THE VEGETATED SHELF SHALL BE PLANTED IN A "NATURALIZED" MANNER WITH PLANTS GROUPED
WITHIN THE VEGETATED SHELF AND SPACED ON -CENTER AS OUTLINED IN THE CHART.
10. IF THE WET POND WAS USED DURING CONSTRUCTION AS FOR EROSION CONTROL, THE BASIN MUST BE GLEANED OUT,
GRADED, APPROPRIATE AREAS COVERED WITH 4" OF TOPSOIL AS SPECIFIED IN NOTE #2 ABOVE, AND VEGETATED WITHIN 14
DAYS OF CONSTRUCTION COMPLETION, THE CONVERSION OF THE DEVICE TO A PERMANENT DEVICE SHOULD NOT OCCUR
UNTIL ALL CONSTRUCTION IS COMPLETE AND THE DRAINAGE AREA TO THE SCM IS COMPLETELY STABILIZED WITH PAVEMENT,
STRUCTURES, AND VEGETATION OR BASED ON ALTERNATIVE DIRECTION BY THE REVIEWING AGENCY. PLANTINGS ON THE
VEGETATED SHELF SHOULD BE INSTALLED PER NOTES ABOVE.
11. THE SCM DRAIN SHOULD BE FULLY OPENED FOR NO MORE THAN 3 DAYS PRIOR TO THE PLANTING DATE TO PRESERVE SOIL
MOISTURE AND WORKABILITY.
12. ALL NEW PLANTINGS ON THE VEGETATED SHELF ARE TO BE WATERED AS REQUIRED DURING INITIAL GROWING SEASON TO
KEEP PLANTS HEALTHY AND PROMOTE GROWTH.
13. A MINIMUM TWO-YEAR WARRANTY PERIOD SHALL BE PROVIDED BY THE CONTRACTOR FOR PLANT SURVIVAL/REPLACEMENT.
14. AT THE END OF THE FIRST YEAR AND AGAIN AT THE END OF THE TWO-YEAR WARRANTY PERIOD, ALL PLANTS THAT DO NOT
SURVIVE MUST BE REPLACED. ESTABLISHMENT PROCEDURES, SUCH AS CONTROL OF INVASIVE WEEDS, ANIMAL AND VANDAL
DAMAGE, MULCHING, RE -STAKING, WATERING, AND MESH OR TUBE PROTECTION REPLACEMENT, SHALL BE IMPLEMENTED TO
THE EXTENT NEEDED TO ENSURE PLANT SURVIVAL. STAKING MUST BE REMOVED AFTER ESTABLISHMENT (APPROXIMATELY 12
MONTHS), TO PREVENT GIRDLING (STRANGLING) OF ALL WOODY PLANTS.

A sediment basin with a permanent riser and an attached skimmer at the
location of the permanent stormwater control measure to remove
72as!nID PRB 1
sediment from construction site runoff during the sites construction.
Components of this basin include a skimmer, coir fiber baffles, the
permanent pond riser and an emergency overflow spillway designed to
release runoff if the riser capacity is exceeded.

Sanford, NC
Date: 6/7/2024
Construction Sequence
1. Stabilize the embankment, interior slopes and surrounding areas with permanent vegetation following installation.
2. Install a minimum of 3 coir fiber baffles in the basin.
3. Restrict the maximum dam height to 25 feet. Dams exceeding 25 feet in height and impounding 50 acre-feet or more
become subject to the NC Dam Safety Act. (Height is measured from the top of the dam to the lowest point on the
downstream toe. Volume is measured at the top of the dam.)
4. Attach the skimmer to the riser 1 foot above the bottom of the basin.
5. Provide Schedule 40 PVC arm pipe with a length of 6 feet to attach the skimmer to the coupling at the barrel pipe. For
skimmer sizes 2.5 inches and smaller, the arm pipe diameter shall be 1.5 inches. For skimmer sizes of 3 inches and larger,
refer to the manufacturer recommendation for arm pipe diameter. Provide a 4-inch diameter Schedule 40 PVC pipe to
attach to the rigid coupling connection of the skimmer and serve as the barrel pipe through the earthen dam or tie into the
riser.
6. Restrict the minimum barrel size to 15 inches for corrugated metal pipe to reduce the potential for failure due to debris
or blockages.
If installing permenant riser and outlet pipe, see stormwater control measure for final design.
7. Construct the diameter of the riser to be 1.2 times that of the barrel pipe diameter. If installing permenant riser and
outlet pipe, see stormwater control measure for final design.
B. Armor the overflow spillway with Class B stone unless otherwise specified.
9. Use Class B stone for anti -flotation for the riser and barrel pipes unless permanent riser and anti -flotation calculations
have been provided with final stormwater control measure calculations.
10. Install a Class B stone pad (4 feet by 4 feet by 12 inches high) directly underneath the skimmer device.
11. Construct the earth dike alongone or more sides if needed. Excavation may be required to provide a minimum surface
, Y q
area and/or a minimum storage volume.
12. Construct the dike of material suitable for and meeting roadway embankment specifications.
13. To facilitate the determination of the maintenance cleanout requirement, place a marker in the basin indicating the
50% volume level.
14. Provide a stone energy dissipator pad at the outlet of the riser barrel.
15. Seed and place matting for erosion control on all interior and exterior slopes of the basin.
Maintenance P
Inspect the basin and riser on a regular basis and after every significant rainfall event (1/2 inch or greater). Inspect the
riser for proper operation. Remove debris from around the riser or the trash rack. Check the skimmer for proper
functioning and to verify that it is not clogged with sediment. Make sure the vent pipe on the skimmer is turned upright.
Inspect the barrel for seepage around the pipe at the outlet. Inspect the embankment, baffles, overflow spillway and outlet
for erosion damage. At a minimum, remove sediment when the basin volume reaches 50% of the total storage volume and
as needed.

particularly important to check the channel
outlet and all road crossings for bank stability
and evidence of piping or scour holes.
Remove all significant sediment
accumulations to maintain the designed
carrying capacity. Keep the grass in a
healthy, vigorous condition at all times, since
it is the primary erosion protection for the

channel (Practice 6.11, Permanent Seeding).
Construction Specifications
1. Remove all trees, brush, stumps, and other objectionable material from the foundation area, and dispose of properly.
2. Excavate the channel, and shape it to neat lines and dimensions shown on the plans plus a 0.2-foot overcut around the
channel perimeter to allow for bulking during seedbed preparations and sod buildup.
3. Remove and properly dispose of all excess soil so that surface water may enter the channel freely.
4. The procedure used to establish grass in the channel will depend upon the severity of the conditions and selection of
species. Protect the channel with severity of the conditions and selection of species. Protect the channel with mulch or a
temporary liner sufficient to withstand anticipated velocities during the establishment period (Appendix 8.05).
