I. NARRATIVE:
DARE COUNTY INTENDS TO CONSTRUCT A PEDESTRIAN WALKWAY SYSTEM ALONG THE WEST SIDE
OF NC 12 ON HATTERAS ISLAND. THE NORTHERN PORTION OF THE SYSTEM EXTENDS
THROUGHOUT THE VILLAGES OF RODANTHE, WAVES AND SALVO. THE SOUTHERN PORTION
EXTENDS THROUGHOUT THE VILLAGE OF AVON. THE CONSTRUCTION CONSISTS OF CONCRETE
SIDEWALKS 5' IN WIDTH AND ELEVATED WOOD WALKWAYS/BRIDGES 8' IN WIDTH WITH SOME
BENCHES AND ADA ACCESS FEATURES EXTENDING BEYOND 8'. CONSTRUCTION IS SCHEDULED TO
BEGIN IN THE WINTER/SPRING OF 2013.
THE NORTHERN PORTION OF THE PROJECT IS APPROXIMATELY 4.34 MILES AND THE SOUTHERN
PORTION IS APPROXIMATELY 3.70 MILES. FOR A TOTAL OF 8.04 MILES. DISTURBANCE SHALL BE
MAINTAINED WITHIN 5' ON EITHER SIDE OF THE SIDEWALK (15' TOTAL) EXCEPT IN ISOLATED
AREAS WHERE SWALE RE -GRADING IS REQUIRED (AS SHOWN ON PLANS). DISTURBANCE FOR
THE CONSTRUCTION OF THE ELEVATED WALKWAYS IN WETLAND AREAS SHALL BE LIMITED TO THE
INSTALLATION OF PILINGS AND FRAMING. APPROXIMATELY 14.6 ACRES ARE TO BE DISTURBED.
THE SIDEWALK ALIGNMENT HAS BEEN SELECTED TO MINIMIZE CONFLICTS WITH EXISTING UTILITIES
AND VEGETATION.
THE SITE IS PRIMARILY WITHIN THE NCDOT RIGHT-OF-WAY, WITH THE EXCEPTION OF
ENCROACHMENTS INTO THE NATIONAL PARK SERVICE AND DARE COUNTY PROPERTY. THESE
ENCROACHMENTS OCCUR AT THE NORTH END OF SALVO AND THE NORTH AND SOUTH ENDS OF
AVON, WHERE NCDOT R/W ENDS AND ALL LANDS ARE OWNED BY THE NATIONAL PARK SERVICE.
THE NPS HAS BEEN INVOLVED IN THE DESIGN PROCESS AND IS GRANTING PERMISSION FOR
THE SIDEWALK. THE SIDEWALK ALSO ENCROACHES INTO THE DARE COUNTY WATER TOWER SITE
IN RODANTHE. TOPOGRAPHY IS LEVEL AND THE SOILS ARE SANDY.
DISTURBED AREAS ARE TO BE STABILIZED WITH TEMPORARY/PERMANENT VEGETATION ACCORDING
TO THE SEQUENCE OF CONSTRUCTION.

IV. SEDIMENTATION EROSION CONTROL NOTES
1. PRIOR TO ANY LAND DISTURBING ACTIVITIES AND AFTER DELINEATION OF THE SIDEWALK
LOCATION AND JURISDICTIONAL AREAS, THE CONTRACTOR SHALL SCHEDULE A
PRE -CLEARING MEETING ON THE SITE WITH THE CONSTRUCTION MANAGER.
2. PRIOR TO THE COMMENCEMENT OF ANY EXCAVATION, THE CONTRACTOR SHALL HAVE
THE APPROPRIATE UNDERGROUND UTILITIES LOCATED.
3. PRIOR TO COMMENCEMENT OF ANY LAND DISTURBING ACTIVITIES, EROSION AND
SEDIMENTATION CONTROL MEASURES IDENTIFIED ON THE EROSION AND SEDIMENT
CONTROL AND THIS PLAN SHALL BE INSTALLED IN ACCORDANCE WITH THE PROJECT
PLANS SPECIFICATIONS.
4. THE CONTRACTOR SHALL ENSURE THAT AREAS OUTSIDE OF THE LIMITS OF LAND
DISTURBANCE AS WELL AS EXISTING IMPROVEMENTS SPECIFICALLY NOTED FOR
PROTECTION ARE NOT ADVERSELY IMPACTED BY ANY CLEARING ACTIVITIES.
5. THE LIMITS OF LAND DISTURBANCE SHALL BE MAINTAINED AS NOTED UNLESS
