GENERAL PERMIT 7 – Construction of a Revetment at a Single Family Home or Duplex Lot  

General Permit 7 authorizes construction of a revetment of a single family home or duplex lot, provided:

  • The revetment meets the definition at N.J.A.C. 7:7-1.5;
  • The single-family home or duplex is not part of a larger development owner or controlled by the same property owner;
  • The eroding shoreline is not located along the Atlantic Ocean, Delaware Bay, Raritan Bay or Sandy Hook Bay;
  • The revetment slope is not steeper than one vertical to two horizontal;
  • Riprap placed in the waterway is limited to that necessary to protect the shoreline;
  • Fill material placed to achieve the required slope is added only to the upland free of large stones and firmly compacted before revetment construction begins;
  • Filter fabric or graded stone filter is installed to prevent loss of slope materials;
  • Revetment stones are angular and blocky, not rounded;
  • An engineer determines the weight of the individual stones based on wave height range for the site;
  • The revetment is placed in such a way as to not result in instability of a coastal bluff or cause erosion of adjacent properties or offshore areas; and
  • Public access is provided in accordance with the public trust rights rule, N.J.A.C. 7:7-9.48, and the public access rule, N.J.A.C. 7:7-16.9.

Please be advised:

  • Placing a revetment in dunes or wetlands is prohibited.
  • Any wetlands disturbed during construction must be restored to pre-construction conditions.

Full details are provided at N.J.A.C.7:7-6.7.

If your project does not meet the requirements of the General Permit 7, it may qualify for another General Permit, Permit-by-rule, or an Individual Permit.  Additional information on these permit types can be found on the Coastal Permitting page.
