In the event that, in the vicinity of any state or local project, comparable, decent, safe and sanitary housing is not available to enable replacement of housing as contemplated by R.S. 38:3105, for whatever reason, then the agency constructing the project may use any method practicable to provide adequate housing, including, but not limited to, payment for the benefit of the displaced person in excess of the sums specified by R.S. 38:3105, acquisition of land and construction of housing, or other methods permitted under federal laws and regulations. This Section shall have both retroactive and prospective effect and shall be interpreted liberally to accomplish the desired result of providing the needed housing.
