COASTAL GENERAL PERMIT 21 – Stabilization of eroded shorelines
The Coastal General Permit 21 authorizes stabilization of erode shorelines along tidal waterways, excluding the Atlantic Ocean. The particulars of this general permit include:
- The materials permitted by this general permit are vegetative materials which are specifically called out at N.J.A.C. 7:7-7.21(a)1. They include live branch cuttings, live facines, live stakes, vegetative cuttings, vegetated earth buttresses, coir fiber products, fiber plugs, plants and clusters, selected plant materials, fiber pallets, fiber carpet, and wood stake anchor systems.
- The plant materials must be chosen and installed in accordance with Chapter 16 of “Streambank and Shoreline Stabilization Protection” of the National Engineering Handbook (NEH), Part 650, 1996, published by the United States Department of Agriculture.
- The stabilization must not have an adverse impact on Special Areas defined at N.J.A.C. 7:7E-3.
- No disturbance to wetlands is allowed.
- If shoreline stabilization will occur outshore of wetlands, it must be designed to minimize changes to tidal circulation, natural contour and/or the natural vegetation of the wetlands.
- No grading is allowed below the spring high water line.
- Bioengineering materials (non-vegetative materials) must be limited to that necessary to protect the shoreline.
- For projects on public lands, public access to the waterfront must be provided and maintained during construction and thereafter.
You can read the full details in the rule at N.J.A.C.7:7-7.21.
If your project does not meet the requirements or limitations of Coastal General Permit 21, it may qualify for a permit-by-rule, other general permit, or a CAFRA or Waterfront Development Individual Permit. Please review those tabs under Coastal Permitting for additional information.
