§ 3. JURISDICTION
The provisions of this Unified Development Code apply generally to all property within the corporate limits of the City of Rockwall and to the lands subject to its zoning jurisdiction as conferred by state law. Those provisions pertaining to the subdivision of land, and those regulations adopted for the primary purpose of protecting water quality or to afford flood protection, apply to all property within the [city's] corporate boundaries and to all property within its extraterritorial jurisdiction (ETJ), as established by Texas Local Government Code chapter 42 and chapter 212. References to jurisdictions or the applicability of specific development regulations appearing elsewhere in this Unified Development Code take precedence over this jurisdictional statement in the event of a conflicting interpretation.
