Development along the coast is regulated by the Central Planning Authority when activities occur landward of the Mean High Water Mark (MHWM). However, when activities extend from the MHWM seaward over seabed that is Crown property, including Crown-owned canals in Governor’s Harbour and Lime Tree Bay, SafeHaven and Snug Harbour (Hyatt canal), such development falls under the jurisdiction of Cabinet. Projects such as docks, launching ramps, groynes and bulkheads built at or originating from mean high water, or dredging and filling works, require approval from Cabinet in the form of a Coastal Works Permit (formerly referred to as a Coastal Works Licence). The purpose of the permit is two-fold: it grants permission by Cabinet to utilise Crown property and thereby avoid trespass issues; and it satisfies section 21 of the National Conservation Law (2013). Furthermore, in accordance with section 34 of the Law, a person who, not being authorised or permitted under the NCL or any other Law commits an offence if they:

“34 (g) directly or indirectly cause or permit any pathogens, dissolved or suspended materials or solids, waste materials or other substances to flow or to be discharged or put into Cayman water;

34 (h) directly or indirectly cut, carves injure, mutilate, remove, displace or break any underwater coral or plant growth or formation in Cayman waters;

34 (i) in Cayman waters, extracts sand, gravel, pebbles, stone, coral or such other material from the seabed by mechanical means or otherwise disturbs the seabed by mechanical means”
