Construction BMP Guide: C103 High-Visibility Fence
High visibility fences can be plastic, metal, or fabric- depending on site conditions. These fences should be used to:
-
Restrict clearing to approved limits.
-
Prevent disturbance of sensitive areas, their buffers and other areas required to be left undisturbed.
-
Limit construction traffic to designated construction entrances, exits, or internal roads.
-
Protect areas where marking with survey tape may not provide adequate protection.
*The contents of this guide are to provide a general overview only. It is users responsibility to ensure all BMPs utilized on their project meet the requirements of their state and local jurisdictions.
