The November 2024 Unified Development Chapter can be downloaded in one large Adobe Acrobat (.pdf) file, including all zoning maps, or individual sections of the text and maps can be downloaded as individual .pdfs below. 

Article 1: General Provisions 

(Sections 50-1 to 50-12)   

Article 2: Zone Districts  

(Sections 50-13 to 50-18) Includes information on zone district minimum requirements (such as lot area and frontage), flood plains and flood hazard management, shoreland, stormwater, and overlay districts (natural resources, historic, airport, skyline, and higher education).

Article 3: Permitted Uses 

(Sections 50-19 to 50-20) Includes a table of uses to determine where certain land uses are allowed, whether the use is allowed without special approvals (permitted use), after having obtained a Special Use Permit (special use), after having obtained an Interim Use Permit (interim use), or if the use is a use only allowed as an accessory to a principal use (accessory use) or temporary use.  Use specific standards are given after the use table to describe special conditions apply to certain uses.

UDC Interpretations

In accordance with Section 50-10, the Land Use Supervisor is authorized to interpret provisions of the UDC, including uses not already classified as well as any provisions that may be ambiguous. These interpretations are an interim step until the City Council can officially amend the UDC.  Below are the interpretations made since the last UDC update:

• 20-004 Replacement of Non-Conforming Structures

Regulating and Concept Plans

Sites zoned Residential-Planned (R-P) and Mixed Use-Planned (MU-P) are required to have a regulating plan to govern land uses and development of their specific area.  Below are recent regulating plans.
