Environmental Enhancements to the Unified Development Ordinance

The goal of the Environmental Enhancements to the Unified Development Ordinance (EEUDO) project is to look closely at the environmental protections codified in the Unified Development Ordinance (UDO) and recommend improvements.

In October 2008 the Joint City-County Planning Committee (JCCPC) formed a steering committee made up of citizens, developers, and field professionals to provide input and policy recommendations in four areas of environmental concern: sedimentation and erosion control, water quality and stream buffers, tree protection, and site preparation. The steering committee met monthly from November 2008 until May 2009, and presented its policy recommendations to the JCCPC in June 2009. The steering committee continues to meet on an ad hoc basis to review draft text amendments within the scope of the EEUDO project.
