Issue 4: Impact of existing and potential shoreline debris during a storm event

Marine and shoreline debris can be hazardous to coastal infrastructure during high wind and storm surge events. Large debris, such as old docks, pilings, and Navy boat bumpers (known as camels), can become lodged in sensitive estuarine habitat and along urban shorelines, and may remain there for years, as happened with Hurricane Bob. Increased development in the floodplain will create additional debris. In the 1938 and 1954 hurricanes, a tremendous amount of debris flowed into the upper Bay region and acted as battering rams, greatly increasing the level of destruction. Reducing development or increasing building standards will lessen the potential for infrastructure to turn into harmful debris during storms.

Recently RIEMA and DEM developed a draft post-disaster debris management plan. Current CRMC policy states that upon transfer of property ownership, the new owner is required to remove derelict marine materials and to clean up the site (RICRMP Section 300.4). Coordination among RIEMA, DEM, and CRMC on this issue is crucial.
