NOTE: ANY FUTURE DEVELOPMENTS ON INDIVIDUAL LOTS
RESULTING FROM THIS DEVELOPMENT PROJECT SHALL
OBTAIN A HENDERSON COUNTY STORMWATER PERMIT FOR
ADDITIONAL PROPOSED IMPERVIOUS SURFACES.
NOTE: SEE DETAILS FOR EROSION AND SEDIMENTATION
CONTROL AND STORMWATER DISCHARGES SELF-INSECTION
AND REPORTING REQUIREMENTS.
NOTE: HARPER CREEK AND THE UNNAMED TRIBUTARY
ADJACENT TO N. CLEAR CREEK ROAD ARE DEPICTED PER
SURVEY. THE WETLANDS AND ASSOCIATED AQUATIC BUFFER
AS SHOWN ARE ESTIMATED. A FINAL JURISDICTIONAL
DETERMINATION BY THE US ARMY CORPS OF ENGINEERS IS
IN PROGRESS TO DEFINE THE WETLAND BOUNDARIES. A FINAL
WETLAND SURVEY WILL BE CONDUCTED AND INCORPORATED
INTO THE PROJECT DESIGN. ALL PROJECT CONSTRUCTION
ACTIVITIES RELATED TO REGULATED WATERS AND ASSOCIATED
AQUATIC BUFFERS SHALL BE BASED ON ACTUAL LOCATIONS
AND RELATED SURVEY DATA.

NOTE: A TROUT BUFFER WAIVER IS REQUIRED FROM
THE NORTH CAROLINA DEPARTMENT OF ENVIRONMENTAL
QUALITY, LAND QUALITY SECTION, PRIOR TO ANY LAND
DISTURBANCE WITHIN THE AQUATIC BUFFER.
