d- Use permit (Permiso de uso): A substantiated administrative resolution by which the Municipality, through an agreement of the Municipal Council, grants unilaterally to an administered party, the use of a specific parcel of the restricted zone (zona restringida) of the ZMT under its jurisdiction where no coastal regulatory plan (plan regulador costero) exists. This administrative act is revocable at any time for reasons of opportunity, convenience, or merit for the public interest. It authorizes a precarious use and not a subjective right in the strict sense, so the permit holder (permisionario) will be unable: to carry out constructions on the site or any other activity that affects the natural conditions of the zone or that hinders the free use of the public zone.
e- Civil fruits (Usufructo): The usufruct corresponds to the use of the civil fruits, understood as the right that the municipality has, by legal provision, to receive special contributions for use permits or improvements (mejoras) when they exist.
f- ZMT: Zona Marítimo Terrestre.
g- Restricted Zone (Zona Restringida): Public domain area encompassing one hundred fifty meters along the coastline, measured from the boundary of the public zone.
