COASTAL GENERAL PERMIT 19 – Construction of piers, docks including jetski ramps, pilings and boatlifts in manmade lagoons

The Coastal General Permit 19 authorizes construction of piers, docks, jetski ramps, pilings and boatlifts in man-made lagoons.   Particulars for this general permit include the following:

  • The waterway where the structure will be located must meet the definition of man-made lagoon found at N.J.A.C. 7:7-1.3.
  • The structures are for non-commercial, recreational use at an individual single family or duplex lot.
  • The structures do not extend more than 20 percent of the width of the man-made lagoon.
  • Except for floating docks, the dock must clear the ground or water surface at mean high water by at least half the width of the dock – for instance a 6 foot wide dock has 3 feet of air between the bottom of the dock and the water at mean high water, except for piers built across wetlands the height must be 4 feet.
  • The maximum width of the dock is 8 feet.  If the dock crosses wetlands the width is 6 feet.
  • The proposed structures do not hinder navigation or access to adjacent structures.
  • Docks must be spaced such that there is not more than 8 feet of continuous width over water.
  • Any wetlands disturbed during construction must be restored to pre-project conditions.
  • Docks, ramps and floats must be located no less than 4 feet from adjacent property.
  • Jetski ramps or floats may not be wider than 8 feet.
  • If you have docks greater than eight feet in width that were constructed prior to September 1978 and you want to increase your coverage over water, you must reduce the oversized docks to 8 feet in width.

You can read the full details on pages 136-137 in the rule at N.J.A.C.7:7.

If your project does not meet the requirements or limitations of Coastal General Permit 19, it may qualify for a permit-by-rule, other general permit, or a Waterfront Development Individual Permit.  Please review those tabs under Coastal Permitting for additional information.
