D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The existing stream channels are so incised and degraded that a new channel is being designed in order to stabilize and
restore stream function to this section of channel while reducing sediment from entering Falls Lake. The new channel will
have an opportunity to function with a floodplain again and help with nutrient removal.
Sediment and Erosion control measures will be designed in order to keep sediment onsite and to temporarily stabilize the site.
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Sediment and Erosion control measures will be used in order to minimize the impact on the stream ecosystem. Such
measures will be rock dams, coir fiber matting, silt fence, wood mat crossings, pump -around, geolifts, and working offline.

CONSTRUCTION SEQUENCE
A CEC PROJECT MANAGER WILL PROVIDE CONSTRUCTION QUALITY ASSURANCE DURING THE
CONSTRUCTION PHASE OF THIS PROJECT. THE FOLLOWING CONSTRUCTION SEQUENCE
SHALL BE USED DURING IMPLEMENTATION OF THE PLAN.
1. PRIOR TO BEGINNING ANY LAND DISTURBING ACTIVITIES, NOTIFICATION AND APPROVAL
MUST BE GRANTED FROM US ARMY CORP OF ENGINEERS AND NCDWR DIVISION OF
WATER QUALITY.
2. THE CONTRACTOR SHALL CONTACT NORTH CAROLINA 811 CENTER (1.800.632.4949)
AND LAND QUALITY (919.791.4200) BEFORE ANY EXCAVATION.
3. THE CONTRACTOR WILL MOBILIZE EQUIPMENT AND MATERIALS TO THE SITE BY
UTILIZING THE ACCESS ROAD OFF REDWOOD ROAD (SHOWN ON THE PLANS).
4. THE CONTRACTOR WILL UTILIZE THE ACCESS ROAD AND STREAM CROSSINGS AS
SHOWN ON THE PLANS. CONSTRUCTION TRAFFIC SHALL BE RESTRICTED TO THE AREA
DENOTED AS "LIMITS OF DISTURBANCE"ON THE CONSTRUCTION PLANS.
S. THE CONTRACTOR SHALL INSTALL TEMPORARY SILT FENCE AROUND THE STAGING
AREAS. THE CONTRACTOR WILL NOT PLACE EXCAVATED FILL INTO THE OLD CHANNEL
UNTIL THE NEW CHANNEL IS COMPLETE AND WATER HAS BEEN DIVERTED INTO THE
NEW CHANNEL
6. THE CONTRACTOR SHALL INSTALL ALL TEMPORARY STREAM CROSSINGS AS SHOWN ON
PLANS IN ACCORDANCE WITH THE NC EROSION AND SEDIMENT CONTROL PLANNING
AND DESIGN MANUAL DITCHES AND STREAM REACHES ON SITE WILL BE LEFT OPEN
DURING THE INITIAL_ STAGES OF CONSTRUCTION TO ALLOW FOR DRAINAGE AND TO
KEEP SITE ACCESSIBLE.
7. CONTRACTOR SHALL BEGIN CONSTRUCTION ON EACH STREAM REACH AND COMPLETE
THAT SPECIFIC STREAM REACH BEFORE MOVING TO THE NEXT REACH. THE NEW
CHANNEL SECTIONS SHALL BE LEFT OPEN ON THE DOWNSTREAM END TO ALLOW FOR
DRAINAGE DURING RAIN EVENTS. AT NO TIME WILL CLEARING AND GRUBBING
PROGRESS BEYOND THE SECTION OF CHANNEL THAT IS BEING CUT UNLESS WORKING
WITH MORE THAN ONE CREW (I.E. CANNOT REMOVE TREES ON BETWEEN STATIONS
14+22 TO 16+00 WHEN YOU ARE WORKING BETWEEN STATIONS 10+00 TO 14+00
ALONG THE MAIN STEM).
8. MAJORITY OF THE PROJECT IS OFFLINE CONSTRUCTION, CONTRACTOR WILL INSTALL
TYPICAL PUMP AROUND OPERATION WHEN SUFFICIENT FLOW IS PRESENT.
MAINSTEM OF PANTHER CREEK (Mi.M2) & TRIS (UT1) CONSTRUCTION
9. ONCE STAGING AND TEMPORARY CROSSINGS ARE COMPLETE, THE CONTRACTOR WILL
START WITH M1. MI IS A PERENNIAL CHANNEL AND TYPICALLY MAINTAINS FLOW. IF
SUFFICIENT FLOW IS PRESENT, THEN A PUMP -AROUND IS NEEDED (SEE X22 AND
#23 FOR PUMP -AROUND INSTRUCTIONS).
10. ONCE THE SECTIONS OF M1 HAVE BEEN EXCAVATED TO DESIGN GRADES, INSTALL
IN -STREAM STRUCTURES, SEED AND MAT, AND READY THE CHANNEL TO ACCEPT
FLOW. ONE REACH SHOULD BE COMPLETE WITH ALL STRUCTURES, SEED, AND
MATTING BEFORE MOVING ONTO THE NEXT REACH.
11. THE CONTRACTOR WILL MOVE TO M2 WHEN MI IS COMPLETE. M2 IS A PERENNIAL
CHANNEL AND TYPICALLY MAINTAINS FLOW. IF SUFFICIENT FLOW IS PRESENT, THEN A
PUMP -AROUND IS NEEDED (SEE #22 AND 123 FOR PUMP -AROUND INSTRUCTIONS).
12. ONCE THE SECTIONS OF M2 HAVE BEEN EXCAVATED TO DESIGN GRADES, INSTALL
IN -STREAM STRUCTURES, SEED AND MAT, AND READY THE CHANNEL TO ACCEPT
FLOW. ONE REACH SHOULD BE COMPLETE WITH ALL STRUCTURES, SEED, AND
MATTING BEFORE MOVING ONTO THE NEXT REACH.
13. THE CONTRACTOR WILL MOVE TO UTI WHEN M2 IS COMPLETE UT1 IS AN
INTERMITTENT CHANNEL AND ONLY MAINTAINS FLOW SEASONALLY. IF SUFFICIENT FLOW
IS PRESENT, THEN A PUMP -AROUND IS NEEDED (SEE #22 AND /23 FOR
PUMP -AROUND INSTRUCTIONS).
14. ONCE THE SECTIONS OF UT1 HAVE BEEN EXCAVATED TO DESIGN GRADES, INSTALL
IN -STREAM STRUCTURES, SEED AND MAT, AND READY THE CHANNEL TO ACCEPT
FLOW. ONE REACH SHOULD BE COMPLETE WITH ALL STRUCTURES, SEED, AND
MATTING BEFORE MOVING ONTO THE NEXT REACH.
15. IMMEDIATELY UPON COMPLETION OF BANK GRADING, THE SLOPE WILL BE RESEEDED,
MULCHED, AND MATTED WITH EROSION CONTROL FABRIC. THE CONTRACTOR SHALL
ONLY WORK IN AREAS THAT CAN BE SEEDED, MULCHED, AND MATTED WITHIN THE
SAME DAY.
16. THE SECTIONS ALONG M1 (10+00 TO 14+86), M2 (14+86 TO 36+85), AND UT1
(10+00 TO 19+19), ARE AREAS OF STRUCTURE INSTALLATION AND REQUIRE THE USE
OF A TEMPORARY PUMP -AROUND OPERATION WHEN SUFFICIENT FLOW IS PRESENT.
PUMP -AROUND OPERATIONS ARE TO BE USED IN ORDER TO DIVERT FLOW AROUND
THE STREAM SECTION BEING CONSTRUCTED TO THE EXISTING CHANNEL DOWNSTREAM.
THE CONTRACTOR SHALL INSTALL TEMPORARY ROCK DAMS AND PUMP -AROUND
OPERATIONS WHENEVER FLOW IS SUFFICIENT. THE PORTION OF THE CHANNEL
ISOLATED SHALL BE DEWATERED AND THE REMOVED WATER SHALL FLOW THROUGH A
SPECIAL STILLING BASIN. THE CONTRACTOR WILL NOT PLACE EXCAVATED FILL INTO
THE OLA CHANNEL UNTIL THE NEW CHANNEL IS COMPLETE AND WATER HAS BEEN
DIVERTED INTO THE NEW CHANNEL
23. ONCE CONSTRUCTION IN A PUMP -AROUND AREA HAS BEEN COMPLETED, REMOVE ALL
PUMP -AROUND MATERIALS AND TURN THE WATER INTO THE NEW CHANNEL
24. UPON COMPLETION OF THE NEW CHANNEL, ALL DISTURBED FLOODPLAIN AREAS
INCLUDING STAGING AREAS AND HAUL ROADS, SHALL BE SEEDED AND COVERED WITH
MULCH. TREES SHALL BE PLANTED IN ACCORDANCE WITH THE PLANTING PLAN.
PERMANENT SEEDING MIXTURES SHALL BE APPLIED AS SHOWN ON THE VEGETATION
PLAN. TEMPORARY SEEDING SHALL BE APPLIED IN ALL AREAS SUSCEPTIBLE TO
EROSION (I.E. DISTURBED DITCH BANKS, STEEP SLOPES, AND SPOIL AREAS) SUCH
THAT GROUND COVER IS ESTABLISHED WITHIN 21 WORKING DAYS FOLLOWING
COMPLETION OF ANY PHASE OF GRADING. PERMANENT GROUND COVER SHALL BE
ESTABLISHED FOR ALL DISTURBED AREAS WITHIN 15 WORKING DAYS OR 90 CALENDAR
DAYS (WHICHEVER IS SHORTER) FOLLOWING COMPLETION OF CONSTRUCTION.
25. ALL AREAS SHOULD BE SEEDED AND MULCHED BEFORE LEAVING THE PROJECT REACH.
REMOVE TEMPORARY STREAM CROSSINGS. ALL WASTE MATERIAL MUST BE REMOVED
FROM THE PROJECT REACH.
26. THE CONTRACTOR SHALL ENSURE THAT THE REACH IS FREE OF TRASH AND LEFTOVER
MATERIALS PRIOR TO MOBILIZATION OF EQUIPMENT FROM THE REACH.

SPECIAL NOTES FOR NATURAL STREAM DESIGN
A.AS-BUILT DRAWINGS - DURING CONSTRUCTION, THE CONTRACTOR AND THE
ENGINEER SHALL WORK TOGETHER TO MAINTAIN A SET OF PRINTS SHOWING ANY CHANGES
OR CORRECTIONS IN RED. THESE PRINTS SHALL BE SUBMITTED TO THE ENGINEER AT THE
COMPLETION OF THE WORK.
B. STREAM RESTORATION DEFINITIONS
1. BANKFULL ELEVATION - BANKFULL ELEVATION IS THE POINT OF INCIPIENT FLOODING
IN AN ALLUVIAL CHANNEL.
2. FLOOOPLAIN SILL, - A FLOODPLAIN SILL IS THE BURIED EXTENSION OF THE
STRUCTURE AND IS PERPENDICULAR TO THE FLOW DIRECTION OF THE BANKFULL
CHANNEL ACROSS THE BANKFULL BENCH OR FLOODPLAIN
3. FOOTER anUR PERS - FOOTER BOULDERS ARE PLACED TO PROVIDE A FOUNDATION
FOR THE SURFACE BOULDERS IN EACH HYDRAULIC STRUCTURE. THE LOWEST COURSE
OF FOOTER BOULDERS ARE BURIED IN THE CHANNEL TO A DEPTH BELOW THE
CALCULATED OR MEASURED SCOUR DEPTH. FOOTER BOULDERS SHALL BE DURABLE
LIMESTONE WITH DIMENSIONS SHOWN IN THE DETAILS. TYPICALLY, FOOTER BOULDERS
ARE BURIED IN THE CHANNEL BOTTOM AND NOT SEEN WHEN THE STRUCTURE IS
COMPLETED. ALL SURFACE BOULDERS FOR ALL STRUCTURES REQUIRE FOOTER
BOULDERS UNLESS BEDROCK IS ENCOUNTERED AT THE PROPOSED ELEVATION OF
FOOTER BOULDERS.
4. SURFACE BOULDERS - SURFACE BOULDERS ARE THE TOP -MOST COURSE OF
BOULDERS USED IN EACH CROSS -VANE OR OTHER ROCK STRUCTURE. ALL SURFACE
BOULDERS CAN BE SEEN PROTRUDING FROM THE WATER SURFACE DURING
EXTREMELY LOW FLOWS. SURFACE BOULDERS SHALL BE DURABLE LIMESTONE WITH
DIMENSIONS SHOWN IN THE DETAILS.
5. THALWEG - THE THALWEG IS THE LOWEST POINT OF THE BANKFULL CHANNEL
DESCRIBED BY THE STREAM PROFILE, THIS ELEVATION IS THE REFERENCE FOR ALL
ELEVATIONS ON OR ALONG THE CHANNEL AND HYDRAULIC STRUCTURES DESCRIBED IN
THIS SECTION AND IN THE PROJECT DRAWINGS.
6. VANE ANGLE - THE VANE ANGLE IS THE SMALLEST ANGLE MEASURED BETWEEN A

VANE INTERSECTS THE BANK. THE VANE ANGLE SHALL BE BETWEEN TWENTY PERCENT
(207) AND THIRTY PERCENT (309.), OR AS SPECIFIED IN THE STREAM RESTORATION
DATA TABLE.
7. VANE LENGTH - THE VANE LENGTH IS THE DISTANCE BETWEEN THE UPSTREAM LIMIT
OF THE VANE ARM AT THE CHANNEL BED TO THE DOWNSTREAM INSERTION POINT OF
THE VANE ARM INTO THE STREAM BANK.
8, VANE SLOPE - THE VANE SLOPE IS THE SLOPE OF THE VANE ARM FROM THE
UPSTREAM LIMIT AT THE CHANNEL BED TO THE DOWNSTREAM INSERTION POINT OF
THE VANE ARM INTO THE STREAM BANK. THE VANE SLOPE SHALL BE BETWEEN
TWO PERCENT (27) AND SEVEN PERCENT (77) OR AS SPECIFIED IN THE STREAM
RESTORATION DATA TABLE AND THE VANE ARMS SHALL TIE INTO THE BANKS AT HALF
TO THREE QUARTERS OF THE BANKFULL ELEVATION.
9. SUBSTRATE RESTORATION - SUBSTRATE RESTORATION IS DESIGNED TO REPLACE AND
RESTORE COARSE SUBSTRATE (GRAVEL, COBBLE, AND BOULDER) TO THE STREAM
CHANNEL IN CASES WHERE COARSE SUBSTRATES OR BEDROCK ARE ABSENT
FOLLOWING CHANNEL EXCAVATION. THE PURPOSE OF SUBSTRATE RESTORATION IS TO
PROVIDE NATURAL SUBSTRATE AND EROSION AND SCOUR PROTECTION IN THE
CHANNEL
10. BASE FLOW - FOR THE PURPOSE OF THESE STREAM DESIGN SPECIFICATIONS, A
FLOW EQUAL TO ONE CUBIC FOOT PER SECOND PER SQUARE MILE OF DRAINAGE
AREA.
C. FLOODPLAIN AND CHANNEL CONSTRUCTION
1. THE CONTRACTOR SHALL STAKE OUT THE PROPOSED STREAM CENTERLINE AND
STRUCTURE LOCATIONS FOR APPROVAL BY THE ENGINEER BEFORE INITIATING
EXCAVATION. DEPENDING ON THE SITE CONDITIONS, SOME SHIFTING OF THE STREAM
CHANNEL AND VANE STRUCTURES MAY BE NECESSARY. ANY COST ASSOCIATED WITH
CHANGING CHANNEL ALIGNMENT AND STRUCTURE LOCATIONS SHALL BE CONSIDERED
INCIDENTAL TO CONSTRUCTION.
2. THE PROPOSED STREAM CHANNEL SHALL BE CONSTRUCTED BY FIRST EXCAVATING THE
FLOODPLAIN TO THE ELEVATIONS AND DIMENSIONS SPECIFIED ON THE STREAM
MITIGATION GRADING PLAN. THE PROPOSED STREAM CHANNEL SHALL THEN BE
EXCAVATED TO THE PROPER DEPTHS INDICATED ON THE PROFILE AND
CROSS-SECTIONS. THIS SHALL BE DONE AS UNCLASSIFIED EXCAVATION AND IS
TYPICALLY ACCOMPLISHED WITH A TRACK EXCAVATOR WITH HYDRAULIC THUMB. ANY
STOCKPILING OR DOUBLE -HANDLING OF MATERIALS NECESSARY TO BUILD THE
CHANNEL SHALL BE CONSIDERED INCIDENTAL TO CONSTRUCTION.
D. FILTER FABRIC
1. NON -WOVEN FILTER FABRIC SHALL ONLY BE USED WHEN COVERING THE ROCK
SECTION OF A STRUCTURE. CONTRACTOR SHALL USE US FABRICS US205NW FABRIC
OR EQUIVALENT.
2. WOVEN FILTER FABRIC SHALL ONLY BE USED WHEN COVERING THE WOODY SECTION
OF A STRUCTURE. CONTRACTOR SHALL USE US FABRICS US315 FABRIC OR
EQUIVALENT.
