New Jersey Statutes Title 27. Highways 27 § 7-80

a. If a project cannot proceed on a timely basis because comparable replacement dwellings are not available, and the agency determines that such dwellings cannot otherwise be made available, the agency may take such action as is necessary or appropriate to provide such housing by use of funds authorized for such project. This shall be done on a case-by-case basis for good cause as determined in accordance with such regulations as the commissioner may issue. The regulations shall be consistent with applicable federal program requirements.

b. No person shall be required to move from his dwelling on account of any program or project undertaken by any agency, unless the agency is satisfied that a comparable replacement dwelling is available to such person.
