The Unified Development Code (UDC), which became effective July 1, 2011, is a comprehensive document designed to consolidate the City's former Zoning Ordinance, Platting Ordinance, and other developmental regulations.

The purpose of the UDC is based on three principles:

  1. A one-book resource for all regulations pertaining to development.
  2. The UDC is written in easy to understand, everyday language.
  3. The UDC is organized to promote flow, consistency, and the ability to find information easily.
