(a) Before voting on the enactment of a proposed subdivision and land development ordinance, the governing body shall hold a public hearing thereon pursuant to public notice. A brief summary setting forth the principal provisions of the proposed ordinance and a reference to the place within the municipality where copies of the proposed ordinance may be secured or examined shall be incorporated in the public notice. Unless the proposed subdivision and land development ordinance shall have been prepared by the planning agency, the governing body shall submit the ordinance to the planning agency at least 45 days prior to the hearing on such ordinance to provide the planning agency an opportunity to submit recommendations. If a county planning agency shall have been created for the county in which the municipality adopting the ordinance is located, then, at least 45 days prior to the public hearing on the ordinance, the municipality shall submit the proposed ordinance to said county planning agency for recommendations.

(b) Within 30 days after adoption, the governing body of a municipality, other than a county, shall forward a certified copy of the subdivision and land development ordinance to the county planning agency or, in counties where no planning agency exists, to the governing body of the county in which the municipality is located.
