When retaining walls, terraces, embankment slopes or similar types of earthen retaining devices are necessitated, they shall be kept in good repair or otherwise maintained so as to keep the site and surrounding areas free of debris and dirt.

Where a parking area is proposed on a site having a slope greater than ten (10%) percent, regardless of size, it shall be terraced, utilizing retaining walls or properly reinforced embankment slopes and providing for adequate safety, stability and drainage.

To preserve the integrity of pavements, embankments and excavations for paved areas, slope returns shall be provided with slopes no steeper than one (1) foot vertical rise for every three (3) feet of horizontal distance. At no time shall an embankment slope that is not reinforced, or any other earthen material having a greater elevation than the adjacent pavement area, have a slope exceeding a ratio of three to one (3:1).

All development on tidal lagoons, navigable waterways or other bodies of water, either existing or proposed, shall provide for bulkheading. All development on non-tidal bodies of water, either existing or proposed, shall provide for bulkheading or other appropriate permanent bank stabilization, acceptable to the Board. In no case shall bank slopes, bulkhead, rip-rap, revetments, or other elements of bank stabilization be located within required minimum yard areas.

Bulkheads may be constructed of treated timber, reinforced concrete, marine alloy steel or other materials in accordance with approved details (if adopted) and a detailed design to be submitted by the developer in each case for approval by the Township Engineer, and such other approval authorities, including, but not limited to, the United States Army Corps of Engineers, as may be necessary.

New or reconstructed lagoons shall have a minimum width of one hundred (100) feet and be provided with suitable turning basins.

The Board may consider waiver and/or modification of this requirement when necessary to preserve wetlands or other natural features, provided that minimum lot sizes are maintained and that all development may be made reasonably secure from erosion.
