Access Management Principles
Model Overlay Ordinance
The model overlay ordinance (PDF) is a tool that local units of government may use to regulate access in a manner that supports local growth and economic development while conforming with MnDOT's access management guidelines.
Key components of the model overlay ordinance:
- Provides legal basis for implementation of access management plans
- Does not change existing underlying zoning
- Establishes access standards for subdivisions and site plans consistent with MnDOT guidelines
- Provides a modification procedure that parallel MnDOT's exception/deviation process to ensure the provision of reasonably convenient and suitable access
- Applies to new and changed land use and access
