Any activity in violation of this part or of any ordinance or regulation adopted pursuant to this part shall be a public nuisance; and such activity may be enjoined or abated by an action filed in the appropriate superior court by the Attorney General on behalf of the department, by any local unit of government affected, or by any person. Upon showing of any activity in violation of this part or of any ordinance or regulation adopted pursuant to this part, a temporary restraining order, a permanent or temporary injunction, or other order shall be granted without the necessity of showing lack of an adequate remedy at law and irreparable injury. The relief granted by the court in an action filed pursuant to this Code section may include, but shall not be limited to, an order requiring the sand dunes, beaches, and submerged lands to be returned to their condition prior to such violation.
