Current through Register Vol. 56, No. 14, July 15, 2024
(a) Coastal
				engineering measures include a variety of non-structural, hybrid, and
				structural shore protection and storm damage reduction measures to manage water
				areas and protect the shoreline from the effects of erosion, storms, and
				sediment and sand movement. Beach nourishment, sand fences, pedestrian crossing
				of dunes, stabilization of dunes, dune restoration projects, dredged material
				management, living shorelines, and the construction of retaining structures
				such as bulkheads, gabions, revetments, and seawalls are all examples of
				coastal engineering measures.
(b)
				Nonstructural, hybrid, and structural shore protection and/or storm damage
				reduction measures shall be used according to the following hierarchy:
1. Non-structural shore protection and/or
				storm damage reduction measures that allow for the growth of vegetation shall
				be used unless it is demonstrated that use of non-structural measures is not
				feasible or practicable. Factors considered in determining whether use of a
				non-structural measure is feasible include the type of waterway on which the
				site is located, the distance to the navigation channel, the width of waterway,
				water depth at the toe of bank, the bank orientation, shoreline slope, fetch,
				erosion rate, the amount of sunlight the site receives, substrate composition,
				and presence of shellfish habitat, submerged vegetation, and wetlands at the
				site. For guidance on measures that may be appropriate depending upon factors
				impacting a site, see Guidance for Appropriate Shoreline Protection and/or
				Storm Damage Reduction Measures for a Site available from the Division of Land
				Use Regulation's website at
http://www.nj.gov/dep/landuse/guidance.html
.
				This guidance follows N.J.S.A 52:14B-3a and does not impose any new or added
				requirements nor can it be used for enforcement purposes.
2. Where the use of non-structural shore
				protection and/or storm damage reduction measures under (b)1 above is
				demonstrated to be not feasible or practicable, then hybrid shore protection
				and/or storm damage reduction measures that allow for the growth of vegetation,
				such as stone, rip-rap, sloped concrete articulated blocks or similar
				structures, or gabion revetments, shall be used. Factors considered in
				determining whether use of a non-structural measure is feasible include the
				type of waterway on which the site is located, the distance to the navigation
				channel, the width of waterway, water depth at the toe of bank, the bank
				orientation, shoreline slope, fetch, erosion rate, the amount of sunlight the
				site receives, substrate composition, and presence of shellfish
				habitat.
3. Where the use of hybrid
				shore protection and/or storm damage reduction measures under (b)2 above is
				demonstrated to be not feasible or practicable, then structural shore
				protection and/or storm damage reduction measures such as bulkheads,
				revetments, sea walls, or other retaining structures shall be used. Factors
				considered in determining whether use of a hybrid shore protection measure is
				feasible include the type of waterway on which the site is located, the
				distance to the navigation channel, the width of waterway, water depth at the
				toe of bank, the bank orientation, shoreline slope, fetch, erosion rate, the
				amount of sunlight the site receives, substrate composition, and presence of
				shellfish habitat.
