Prior to its approval of an urban renewal project, the local governing body shall submit such plan to the planning commission of the municipality, if any, for review and recommendations as to its conformity with the general plan for the development of the municipality as a whole. The planning commission shall submit its written recommendations with respect to the proposed urban renewal plan to the local governing body within 30 days after receipt of the plan for review.
