A. If a project cannot proceed to actual construction because comparable replacement sale or rental housing is not available and the displacing agency determines that the housing cannot otherwise be made available, the displacing agency may take action necessary or appropriate to provide the housing by use of funds authorized for the project.

The displacing agency may use this section to exceed the maximum amounts which may be paid under the Relocation Assistance Act on a case-by-case basis for good cause as determined in accordance with such regulations as the agency or department shall issue.

B. No person shall be required to move from his dwelling on account of any project unless the displacing agency is satisfied that a comparable replacement housing is available to the person.
