Overlay zones have the ability to apply additional standards and criteria for specific properties or districts beyond traditional zoning. Overlay zones may be used to protect or used to promote specific community features or types of development projects, such as affordable housing, mixed use or transit-oriented communities. Overlay zones may be used to help agencies meet specific community goals and address social equity. A major applicable overlay zone is the 2022 MTC Transit-Oriented Communities Policy.
- Apply overlay zones to protect historic, cultural, or environmental features, or to promote specific types of development.
- Update underlying zoning as needed to ensure compatibility between zoning and overlay zones requirements.
