EROSION CONTROL OPTIONS FOR LOT CONSTRUCTION
The Soil Erosion and Sedimentation Control Ordinance requires that anyone conducting a land-disturbing activity
prevent sediment from leaving the disturbed site. Furthermore, conducting any land-disturbing activity
consisting of
one
acre or more requires a permit before beginning the disturbance. This includes disturbance of multiple lots totaling one
acre or more, regardless of proximity to each other within a subdivision; in cases where fill material is stockpiled, needed,
or wasted, the area where this material is stored, coming from, or going to, must be
included in
the total area of
disturbance. Erosion Control measures must be installed prior to any grading or construction on site and maintained
correctly to function properly. Please refer to the NC Erosion and Sediment Control Planning and Design Manual for
specific guidance as it relates to installation and maintenance. The site shall be inspected for maintenance needs weekly
and after each storm event, whichever is sooner.
