THE MALLARD SITE RESTORATION AND CHANNEL RELOCATION PROJECT IS LOCATED OUTSIDE OF
CONTRACTING
A.
PROJECT DESCRIPTION: THE MALLARD STREAM RESTORATION PROJECT IS LOCATED NEAR GROVER, NORTH CAROLINA, NORTH OF MALLARD DRIVE. THE PROJECT REACH IS LOCATED WITHIN A AGRICULTURAL AREA WITH FLOODPLAIN WETLANDS. THE WATERSHED FOR THE PROJECT REACH IS APPROXIMATELY 0.8 SQUARE MILES IN
GROVER, NC, IN CLEVELAND COUNTY. AND FLOWS FROM THE CULVERT UNDER MALLARD DRIVE. THE
AREA AND IS PREDOMINATELY RURAL IN NATURE. LAND USE INCLUDES PASTURE, AGRICULTURE, ROADS, RESIDENTIAL STRUCTURES, AND FORESTED AREAS. THERE ARE NO SIGNIFICANT TRIBUTARIES FLOWING INTO THE STREAM WITHIN THE PROJECT AREA.
PROJECT REACHES INCLUDE APPROXIMATELY 3615 LINEAR FEET OF TWO UNNAMED TRIBUTARIES TO
B.
EXISTING SITE CONDITIONS: THE PROJECT REACH CONSISTS OF A SINGLE THREAD CHANNEL THAT IS IMPACTED BY ONGOING DREDGING, LIVESTOCK ACCESS, MINIMAL RIPARIAN BUFFER, AND BEAVER ACTIVITY. THE IMPACTS OF THESE ACTIVITIES INCLUDE: CHANNEL AGGRADATION, BANK EROSION, LOSS OF RIPARIAN VEGETATION,
BUFFALO CREEK. THE GOAL OF THE PROJECT IS TO RELOCATE A STREAM (REACH 1) TO A NATURALLY
AND ULTIMATELY UNSTABLE CHANNEL DIMENSION, PATTERN, AND PROFILE.
LOW AREA OF THE ADJACENT PASTURE, AND POSSIBLY THE HISTORICAL LOCATION OF THE CHANNEL.
C.
ADJACENT AREAS: THE PROPERTIES ADJACENT TO THE PROJECT SITE CONSIST OF THE AGRICULTURAL FIELDS AND WETLANDS.
THE CURRENT CONDITION OF THE STREAM IS SIGNIFICANTLY DEGRADED AND CURRENTLY

OFF-SITE AREAS: NO OFF-SITE AREAS WILL BE INCLUDED IN THIS PROJECT AS ALL CUT MATERIALS WILL BE USED AS FILL ON SITE.
EXPERIENCING IMPACTS FROM CATTLE ACCESS, DREDGING, MINIMAL BUFFER, AND BEAVER ACTIVITY.

ADDITION TO OTHER APPLICABLE CRITERIA:
• NO MORE THAN 500 LINEAR FEET OF TRENCH MAY BE OPENED AT ONE TIME
• EXCAVATED MATERIAL SHALL BE PLACED ON THE UPHILL SIDE OF TRENCHES
• EFFLUENT FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PASSED THROUGH AN APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH, AND DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS OR OFF-SITE PROPERTY
• MATERIAL USED FOR BACKFILLING TRENCHES SHALL BE PROPERLY COMPACTED IN ORDER TO MINIMIZE EROSION AND PROMOTE STABILIZATION

SURFACE, THE ROAD SURFACE SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER.
(18) REMOVAL OF TEMPORARY MEASURES. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE PROGRAM AUTHORITY. TRAPPED SEDIMENT
AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER EROSION AND SEDIMENTATION.
(19) STORMWATER MANAGEMENT. PROPERTIES AND WATERWAYS DOWNSTREAM FROM DEVELOPMENT SITES SHALL BE PROTECTED FROM SEDIMENT DEPOSITION, EROSION, AND DAMAGE DUE TO INCREASES IN VOLUME, VELOCITY, AND PEAK FLOW RATE OF STORMWATER RUNOFF FOR THE STATED FREQUENCY STORM OF 24-HOUR
DURATION
EROSION CONTROL SEQUENCE:
1. PRIOR TO COMMENCEMENT OF ANY ON-SITE LAND DISTURBING ACTIVITIES, AN ON-SITE PRE CONSTRUCTION MEETING WILL BE HELD SO THAT ALL AFFECTED PARTIES ARE AWARE OF THE CONSTRUCTION SEQUENCE.
2. PRIOR TO ANY CONSTRUCTION ACTIVITIES ON THE PROJECT REACH, THE CONSTRUCTION ENTRANCE, ACCESS ROADS, INITIAL STAGING AREAS AND ANY ASSOCIATED E&S CONTROL MEASURES WILL BE INSTALLED.
3. AFTER E&S CONTROL MEASURES ARE APPROVED BY THE INSPECTOR, PROPOSED GRADING AREAS MAY BEGIN CLEARING AND GRUBBING.
4. CHANNEL GRADING SHALL BE COMPLETED IN SEGMENTS WHICH WILL HAVE PUMP AROUND WHERE APPLICABLE AND BE STABILIZED PRIOR TO BEGINNING WORK ON DOWNSTREAM SEGMENTS.
5. EACH SEGMENT WILL BE BROUGHT TO FINAL GRADE AND STABILIZED PRIOR TO CONTINUING WORK IN THE DOWNSTREAM DIRECTION. WORK AREAS WILL BE STABILIZED DAILY TO ENSURE STABLE FLOW THROUGH THE CHANNEL IN THE EVENINGS.
6. AS FINAL GRADE IS ACHIEVED, STREAM BANKS AND OTHER DISTURBED AREAS WILL BE SEEDED AND MATTED IN ACCORDANCE WITH DETAILS.
7. UPON COMPLETION OF CONSTRUCTION AND APPROVAL FROM COUNTY INSPECTOR, ALL TEMPORARY E&S CONTROL MEASURES WILL BE CLEANED UP AND RECLAIMED.
