Unified Development Code (UDC)

View the UDC text, including the 1989 Shoreline Master Program (SMP) currently in effect. Effective January 16, 2002, the UDC is the set of development regulations that implement the 1998 Comprehensive Plan, as amended. The UDC provides the performance, use, and development standards by which DRD planners review land use applications.


Critical Areas


The UDC also contains Jefferson County's regulatory protections for "critical areas," such as critical aquifer recharge areas, geologically hazardous areas, wetlands and fish and wildlife habitat conservation areas.

Shoreline Management Act


The SMP implements the Shoreline Management Act in conjunction with the State Department of Ecology. For more information on shoreline management, visit the Shoreline Management and Planning page.
