(b) Where any community development activity proposed to be undertaken is to be undertaken in a development project area, harbor improvement project area, housing site development project area, redevelopment project area or urban renewal project area, the community development plan shall state whether the proposed activity is subject to the controls of an adopted plan for such project area and, if so, whether the activity conforms to the plan for such project area. If any such activity is not in conformance with the provisions of the plan for such project area, then the community development plan shall state in what respects the plan for such project area must be modified or amended.
(c) A community development plan may be based to the extent it is consistent with the provisions of this section upon a plan of conservation and development adopted under section 8-23 or a community development action plan. Any nonentitlement municipality may also use its adopted plan of conservation and development or community development action plan, to the extent such plans have been kept current, as determined by the commissioner, or the Secretary of Housing and Urban Development in lieu of preparing a community development plan under this section for the purpose of receiving state financial assistance under section 8-169l.
(d) In the event the United States government, acting by and through the Secretary of Housing and Urban Development, waives any requirement under the provisions of Section 104 of the Housing and Community Development Act of 1974, as from time to time amended, the provisions of subdivisions (1) to (5), inclusive, of subsection (a) of this section affected by such waiver shall not be applicable to any municipality.
