For any level of development on any part of the land you will need to seek a permit application from the National Environment Service which will be decided upon by the Island Environment Authority. This is not a process intended to restrict your development but more to ensure that any intended development is carefully assessed to ensure that no problems will occur to the developer or the environment.
Examples for the scope of development include:
Earthworks of any type or magnitude
Construction of any type
Filling of wetlands
Some levels of development are quickly decided upon and others especially those that interfere with Specific Areas of Concern may take some time to gather the correct information and determine the least detrimental method of continuing with the proposed development.
