Deletes all proposed provisions and replaces them with the following.

Amends GS 160A-385, concerning changes in city zoning and development regulation, by adding a new subsection to require the written consent of the owner regarding a multi-phased development, as defined in GS 160A-385.1(b)(7), for amendments in zoning ordinances, subdivision ordinances, and unified development ordinances to be applicable or enforceable.

Adds a new subdivision to GS 160A-385.1(b) to define multi-phase development to mean a development containing 100 acres or more that (1) is submitted for site plan approval for construction to occur in more than one phase and (2) is subject to a master development plan with committed elements, including a requirement to offer land for public use as a condition of its master development plan approval.
