I. If a program or project undertaken by a displacing agency cannot proceed on a timely basis because comparable replacement dwellings are not available and the head of the displacing agency determines that such dwellings cannot otherwise be made available, then the head of the displacing agency may take such action as is necessary or appropriate to provide such dwellings by use of funds authorized for such project. The displacing agency may use this section to exceed the maximum amounts which may be paid under N.H. Rev. Stat. § 124-A:4 and 124-A:5 on a case-by-case basis for good cause as determined in accordance with rules adopted by the lead agency.
II. No person shall be required to move from a dwelling because of any program or project undertaken by a displacing agency, unless the displacing agency is satisfied that comparable replacement housing is available to such person.
III. The displacing agency shall assure that a person shall not be required to move from a dwelling unless the person has had a reasonable opportunity to relocate to a comparable replacement dwelling, except in the event of:
(a) A major disaster as defined in section 102(2) of the Federal Disaster Relief Act of 1974;
(b) A national emergency declared by the President; or
(c) Any other emergency which requires the person to move immediately from the dwelling because continued occupancy constitutes a substantial danger to the health or safety of such person.
