NOTES
1.) ALL BOUNDARIES ARE APPROXIMATE.
2.) SAMPLE LOCATIONS WERE DERIVED FROM VARIOUS SOURCES AND ARE A MIX OF SURVEYED AND APPROXIMATE LOCATIONS. THEREFORE LOCATIONS ARE DEEMED TO BE APPROXIMATE.
3.) DUKE ENERGY PROPERTY LINES ARE REPRESENTED BASED ON DUKE ENERGY'S INTERPRETATION OF HISTORICAL DOCUMENTED PROPERTY BOUNDARIES AND CURRENT PERSON
COUNTY GIS.
4.) THE WATERS OF THE US DELINEATION HAS NOT BEEN APPROVED BY THE U.S. ARMY CORPS OF ENGINEERS AT THE TIME OF THE MAP CREATION. THIS MAP IS A PRELIMINARY
JURISDICTIONAL DETERMINATION ONLY. THE PRELIMINARY WETLANDS AND STREAM BOUNDARIES WERE OBTAINED FROM AMEC FOSTER WHEELER ENVIRONMENTAL AND
INFRASTRUCTURE INC. NATURAL RESOURCE TECHNICAL REPORT (NRTR) FOR ROXBORO STEAM ELECTRIC PLANT, DATED JUNE 2015.
5.) THE TOPOGRAPHY IS SHOWN FOR REFERENCE PURPOSES ONLY AND SHOULD NOT BE USED FOR DESIGN OR ENGINEERING PURPOSES. THE TOPOGRAPHY BASED ON A COMBINATION OF
SOURCES.
