Hello Mr. Bailey,
Please find the attached edited Notes sheet for the Madison Fish Habitat Restoration Project Phase 1.
Per your request,
1. We have added a line to the narrative specifying that disturbed wetland areas will be restored upon
project completion, and
2. Included a note set " Wetland Restoration Plan" specifying the methods of soil decompaction, vegetation
reestablishment, and soil stabilization.
Please let me know if additional edits or information are needed.
Thank you,
Simon Gregg, EIT, LEED Green Associate
Ecological Engineer

PROJECT NARRATIVE MATERIALS ESTIMATES
m m m
THIS PROJECT INVOLVES THE CONSTRUCTION OF 3 RIFFLES 30'x175' or 2,250-SF IN SIZE ON THE DAN RIVER IN MADISON,
NORTH CAROLINA. THIS PROJECT IS LOCATED ADJACENT TO PROPERTY OWNED BY PINE HALL BRICK. THIS PROJECT
INVOLVES ACCESSING THE RIVER BANK AND BUILDING OF IN STREAM STRUCTURES. ALL WORK SHALL BE SUBJECT TO THE
DIRECTION AND INSPECTION OF THE PROJECT ENGINEER. DISTURBED WETLAND AREAS SHALL BE RESTORED UPON
PROJECT COMPLETION.
THIS PROJECT IS LOCATED IN THE ROANOKE WATERSHED AND THERE IS A FEMA REGULATED FLOODPLAIN IN THE PROJECT
AREA. THE DAN RIVER HAS A REGULATED FEMA FLOODPLAIN ASSOCIATED WITH IT. THIS PROJECT WILL TAKE PLACE WITHIN
THE OPEN WATER IMPOUNDMENT CREATED BY THE LINDSAY BRIDGE DAM ON THE DAN RIVER. CONSTRUCTION FOR THIS
PROJECT SHOULD LAST FROM 14 TO 28 DAYS.
PROJECT NOTES:
THE LOCATION AND ALIGNMENT OF ALL IMPROVEMENTS SHOWN ARE APPROXIMATE. THE FINAL LOCATION AND ALIGNMENT
SHALL BE DETERMINED DURING CONSTRUCTION USING BEST PROFESSIONAL JUDGMENT AND APPROVED BY THE PROJECT
ENGINEER.
MATERIALS LISTS ARE PROVIDED AS AN APPROXIMATION ONLY. CONTRACTOR SHALL INDEPENDENTLY VERIFY THE NUMBER
AND AMOUNT OF STONE, OR OTHER ITEMS NECESSARY TO PROPERLY COMPLETE THE JOB.
THE LATEST VERSION OF THE FOLLOWING STANDARDS APPLIES TO THESE SPECIFICATIONS:
A.NCDOT "STANDARD SPECIFICATIONS FOR ROADS AND STRUCTURES", DATED JULY 2006
B. NCDOT "EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL" 2006
THE CONTRACTOR SHALL CALL THE "CALL BEFORE YOU DIG" TOLL FREE NUMBER TO MAKE SURE THAT ALL UTILITIES ARE
LOCATED AND MARKED. ANY DAMAGE TO EXISTING UTILITIES IS THE RESPONSIBILITY OF THE CONTRACTOR.
ANY DAMAGE RESULTING FROM ACTIONS OF THE CONTRACTOR TO STRUCTURES OR GROUNDS ON SITE WILL BE REPAIRED
OR REPLACED AT THE EXPENSE OF THE CONTRACTOR, TO A QUALITY MEETING OR EXCEEDING THEIR PREVIOUS
STANDARDS.
Disturbed Area = 1.0 AC
Class A, B & 1 Stone (Equal Parts) = 930 TN
Coir Mating = 27 10'x130' rolls
Wooden Stakes, 2' = 3,000
Riparian Seed Mix = 12 LBS
WETLAND RESTORATION PLAN NOTES:
IMPACTS TO AREAS OF KNOWN WETLANDS OR OTHER AREAS DEEMED WETLANDS BY A FIELD ASSESSMENT PERFORMED BY THE PROJECT ENGINEER
SHALL BE RESTORED BY THE FOLLOW PROCEDURE:
1. DECOMPACTION OF SOIL TO A DEPTH OF APPROXIMATELY 0.7 FEET (8 INCHES) VIA TOOTH ROUGHENING AND LOOSE MOUNDING.
A. AS THE EXCAVATOR IS LEAVING AN IMPACTED AREA, THE BUCKET AND BUCKET TEETH SHALL BE USED TO RAKE, SCOOP AND BREAK-UP THE
SOIL TO THE SPECIFIED DEPTH,
B. SOIL MAY BE PARTIAL MOUNDED WITHIN THE NEWLY CREATED DEPRESSION,
C. THIS WILL CREATE A HETEROGENOUS SOIL SURFACE WITH RAISED AND LOWER MICROSITES FOR VEGETATION ESTABLISHMENT,
D. CARE SHALL BE TAKEN TO PREVENT THE CREATION OF STRUCTURES WHICH ARTIFICIALLY MANIPULATE EXISTING SURFACE FLOW PATHS OR
CREATE NEW CONCENTRATE SURFACE FLOW PATHS,
E. THIS SHALL CONTINUE UNTIL THE EXCAVATOR REACHES AN AREA DEEMED UNDISTURBED OR DEEMED NOT WETLANDS BY THE PROJECT
ENGINEER,
2. FOLLOWING DECOMPACTION, DISTURBED AREAS SHALL BE SEEDED WITH THE SPECIFIED RIPARIAN SEED MIX AT A RATE OF 20 LBS/AC.

EROSION CONTROL NOTES:
1. PROVIDE TEMPORARY OR PERMANENT GROUNDCOVER WITH RIPARIAN SEED MIX ON ALL EXPOSED AREAS WITHIN 7
CALENDAR DAYS FOLLOWING COMPLETION OF ANY PHASE OF GRADING. PROVIDE A PERMANENT GROUNDCOVER FOR ALL
DISTURBED AREAS WITHIN 14 WORKING DAYS OR WITHIN 90 CALENDAR DAYS (WHICHEVER IS SHORTER) FOLLOWING
COMPLETION OF CONSTRUCTION OR DEVELOPMENT.
2. THE CONTRACTOR MUST TAKE NECESSARY ACTION TO MINIMIZE THE TRACKING OF MUD OFF SITE AREAS. THE
CONTRACTOR SHALL DAILY REMOVE MUD/SOIL FROM PAVEMENT, AS MAY BE REQUIRED.
3. THE CONTRACTOR SHALL ACCOMPLISH ALL STREAMBANK EXCAVATION FROM OUTSIDE THE ACTIVE CHANNEL WHENEVER
POSSIBLE. ALL DISTURBED STREAMBANK MUST BE STABILIZED WITH SEEDING, MULCH AND EROSION CONTROL MATTING BY
THE END OF EACH WORKDAY.
