I. NARRATNE
THIS PROJECT CONSISTS OF THE DEVELOPMENT OF 5.34 ACRES OF LAND IN KILL DEVIL HILLS, NORTH
CAROLINA. THE DEVELOPER INTENDS TO CONSTRUCT 3 8-UNIT MULTI FAMILY BUILDINGS.
APPROXIMATELY 197,136 SF (4.52 ACRES) ARE TO BE DISTURBED. ALL INFRASTRUCTURE CONSTRUCTION
IS SCHEDULED TO BEGIN IN THE SPRING OF 2008 AND BE COMPLETED WITHIN THREE MONTHS. THE
CONSTRUCTION ENTRANCE IS TO BE PLACED AS DESIGNATED ON THE PLAN. SILT FENCES ARE PROPOSED
TO CONTAIN ANY MOVEMENT OF SOIL DURING CONSTRUCTION. THIS PLAN ILLUSTRATES SILT FENCES
I LOCATION. SHOULD THE NEED FOR ADDITIONAL FENCING BE DETERMINED DURING CONSTRUCTION, IT
WILL BE INSTALLED AS DIRECTED BY THE ENGINEER OR NC DEHNR AGENT.
