Implementing Zoning Ordinance (IZO)
On May 19, 2008, the City Council adopted the Implementing Zoning Ordinance (IZO) to replace the zoning ordinance that was originally adopted in 1973. The intent of the IZO is to provide immediate consistency between the General Plan 2025 that also was adopted on May 19, 2008 and the City's zoning regulations. The IZO includes zoning districts, development standards, and uses consistent with the General Plan 2025 and regulations from the previous zoning ordinance that remain applicable, such as signs, performance standards, and parking. In order to implement General Plan 2025 goals and policies related to hillside development and trees, the IZO also includes Hillside Protection and Tree Preservation chapters.
The IZO implements the goal and polices of the General Plan 2025 by classifying and regulating the uses of land and structures within the City. The IZO includes regulations for the following:
- permitted, conditional, accessory and prohibited uses of land and structures
- building location and height
- parking requirements
The IZO establishes zoning districts that are consistent with the land use designations created by the General Plan 2025. The IZO includes residential, mixed use, commercial, business park, and industrial zoning districts. The zoning district for a specific site is shown on the City's Zoning Map which is located online through the online GIS portal. The IZO includes a use table and development standards table for each zoning district within the city. The use table identifies the permitted, conditionally permitted, and prohibited uses for a building or property within a specific zoning district. The development standards table identifies the location and height requirements for a structure, as well as the minimum lot size requirements for a parcel within a specific zoning district.
