MARCH 2022.
14.THE DESIGN ELEVATIONS AND GRADES SHOWN IN THE DRAWINGS ARE BASED ON THE EXISTING GROUND
SURFACE FROM THE MARCH 2022 SURVEY FROM WHICH ALL COMPUTATIONS OF CUT AND FILL ARE BASED.
DISCREPANCIES BETWEEN THE SURVEYED EXITING GROUND SURFACE AND FIELD CONDITIONS AT THE TIME OF
CONSTRUCTION CAN RESULT IN VARIATIONS OF TOTAL EXCAVATED QUANTITIES. THESE VARIATIONS SHALL BE
CONSIDERED INCIDENTAL TO CONSTRUCTION.
STREAM RESTORATION NOTES AND SPECIFICATIONS
15.FIELD CONDITIONS MAY REQUIRE ADAPTATION OF THE DESIGN AND/OR DETAILS PROVIDED IN THE
DRAWINGS. MINOR VARIATION(S) OR ADAPTATION(S) OF THE PROPOSED WORK SHOWN IN THE DRAWINGS
AND DETAILS ARE CONSIDERED INCIDENTAL TO THE WORK. THE ENGINEER WILL WORK WITH THE
CONTRACTOR TO ADDRESS ANY FIELD CHANGES.

FROM THE ENGINEER.
17.THE CONTRACTOR SHALL MARK THE LOCATIONS OF BANK STABILIZATION STRUCTURES USING SURVEY GRADE
GPS EQUIPMENT FOR REVIEW BY THE ENGINEER BEFORE BEGINNING EXCAVATION AND GRADING.
18.CONTRACTOR SHALL MINIMIZE, TO THE MAXIMUM EXTENT POSSIBLE, IMPACTS TO ADJACENT SIGNIFICANT
TREES.
19.CONTRACTOR SHALL USE AN EXCAVATOR WITH A HYDRAULIC THUMB TO INSTALL BANK STABILIZATION
STRUCTURES.
20.DESIGN ELEVATIONS SHALL BE CONSTRUCTED WITHIN 0.1' (VERTICAL). WIDTHS AND DEPTHS MUST FALL
WITHIN RANGES SHOWN IN THE DRAWINGS AND DETAILS.
21.IF THE EXISTING GROUND IS LESS THAN 0.2' HIGHER THAN THE PROPOSED BANKFULL ELEVATION, IT IS NOT
NECESSARY TO EXCAVATE TO THE PROPOSED ELEVATIONS AND GRADES IN THE CONSTRUCTION DOCUMENTS.
22.BANK STABILIZATION STRUCTURES SHALL BE INSTALLED AS SHOWN IN THE DRAWINGS AND DETAILS. ALL
STRUCTURES SHALL BE FINISHED TO A SMOOTH SURFACE IN ACCORDANCE WITH THE LINES, GRADES AND
ELEVATIONS SHOWN IN THE DRAWINGS AND DETAILS. THE FINISHED STRUCTURE SLOPES AND GRADES SHALL

23.AFTER THE STRUCTURE IS COMPLETE AND NORMAL FLOW IS RESTORED TO THE CHANNEL, SOME
ADJUSTMENT TO THE STRUCTURE OR ADDITIONAL STABILIZATION MEASURE MAY BE NECESSARY TO ACHIEVE
THE DESIRED FUNCTION.
24.THE GRADED RIVER BANKS SHALL BE STABILIZED AS SOON AS POSSIBLE BY TEMPORARY AND PERMANENT
SEEDING, ADDING STRAW MULCH TO BARE SOIL AND INSTALLING EROSION CONTROL MATTING AS SHOWN IN
THE DRAWINGS AND DETAILS. PRIOR TO INSTALLING THE EROSION CONTROL MATTING, PREPARE THE SOIL
SURFACE BY LOOSENING 3 - 6” OF SOIL OR APPLYING 3 - 6” OF TOPSOIL TO THE DESIGN ELEVATIONS AND
APPLY TEMPORARY AND PERMANENT SEED AND THEN STRAW MULCH. SEED SHALL BE BROADCAST EVENLY
OVER THE AREA USING A BROADCAST SPREADER PRIOR TO COVERING WITH THE EROSION CONTROL
MATTING. THE MATTING SHALL BE ROLLED OUT IN THE DIRECTION OF ANTICIPATED RUNOFF. INSTALL
MATTING IN ACCORDANCE WITH THE DETAIL INCLUDED IN THE DRAWINGS. MATTING USED FOR
STREAMBANK STABILIZATION MUST BE CERTIFIED WEED-FREE STRAW OR OTHER NATURAL WEED-FREE /
NON-PROPAGATING VEGETATIVE MATERIALS. REWORKING OF AREAS THAT DO NOT ESTABLISH VEGETATION
OR BECOME UNSTABLE SHALL BE NECESSARY IN THE MATTING SEPARATES FROM THE SOIL.
25.TOPSOIL SHALL BE REMOVED FROM EXCAVATION AND FILL AREAS PRIOR TO EXCAVATION AND GRADING AND
RE-APPLIED TO AREAS AFTER ROUGH GRADING IS COMPLETE. 2 - 4” OF TOPSOIL SHALL BE PLACED ON
DISTURBED AREAS TO THE ELEVATIONS AND GRADES INCLUDED IN THE DRAWINGS. EROSION AND
SEDIMENTATION CONTROL NOTES AND SPECIFICATIONS.

AREAS AND TEMPORARY STOCK PILE AREAS.
31.THE TURBIDITY STANDARD OF 50 NTUS (NEPHELOMETRIC TURBIDITY UNITS) SHALL NOT BE EXCEEDED AS
DESCRIBED IN 15A NCAC 02B .0200. APPROPRIATE SEDIMENT AND EROSION CONTROL PRACTICES MUST BE
USED TO MEET THIS STANDARD. [15A NCAC 02B .0211 (21)].
32.EQUIPMENT SHALL BE WELL-MAINTAINED, CLEANED PRIOR TO MOBILIZATION, AND CHECKED DAILY FOR
LEAKS OF PETROLEUM PRODUCTS. FUELING, LUBRICATION AND GENERAL EQUIPMENT MAINTENANCE

PROJECT SITES WHERE THE WATERSHED SIZE IS LESS THAN 5 SQUARE MILES.
36.A TEMPORARY DIVERSION SHALL BE USED TO DURING ALL STREAM RESTORATION AND STABILIZATION WORK
AS SHOWN IN THE DETAILS.
37.THE STREAM BANKS, IN-STREAM STRUCTURES AND WORK AREA MUST BE STABILIZED AT THE END OF EACH
DAY BEFORE THE TEMPORARY IN-STREAM DIVERSIONS AND PUMP AROUNDS ARE REMOVED AND FLOW IS
RETURNED THE FULL CHANNEL.
38.EROSION CONTROL MATTING THAT INCORPORATES PLASTIC MESH AND/OR PLASTIC TWINE SHALL NOT BE
USED ALONG STREAMBANKS OR WITHIN WETLANDS. DISTURBED AREAS SHOULD BE SEEDED, MULCHED,
AND/OR MATTED AS SOON AS POSSIBLE, PREFERABLY AT THE END OF EACH WORKDAY. [15A NCAC 02B .0201]
39.IF BORROW OR WASTE MATERIAL IS REQUIRED OR GENERATED DURING GRADING OPERATIONS, AN
APPROVED EROSION AND SEDIMENT CONTROL PERMIT MUST BE SECURED FOR THE BORROW OR WASTE
MATERIAL SITE PRIOR TO INITIATION OF ANY LAND DISTURBING ACTIVITY. [15A NCAC 04B .0110].
QUANTITIES AND MATERIALS NOTES AND SPECIFICATIONS
