N.J. Stat. § App.A:9-51.5
When the governing body of any municipality bordering on the Atlantic ocean or Delaware bay shall find that there exists a threat or danger to life and property by reason of the damage to or the destruction of sand barriers and other natural or manmade barriers which protect the municipalities, and that it is necessary to the health, safety and welfare of the municipality to repair, restore, replace or construct such protective barriers, such governing body may, by resolution, as an exercise of the police power of the State designate the properties required for the purpose of providing such protective barriers and authorize the appropriate municipal or governmental officials or agencies or the representatives thereof to enter immediately upon such property to take control and possession thereof, and to do such acts as may be required, including removing, destroying or otherwise disposing of any property located thereon without first paying any compensation therefor.
Such resolution shall provide that no entry shall be made upon such property for a period of at least 10 days following the passage of such resolution, unless the governing body shall find that the public safety and interest requires that entry be made within a shorter period of time. In such case, entry may be made after the expiration of such time period as shall be fixed by the resolution.
