What is the difference between local zoning ordinances and the state’s critical area law and regulations?
Maryland’s Critical Area Program is based on State law included in the Natural Resources Article of the Annotated Code of Maryland. Implementation provisions are found in the critical area regulations in Title 27 of the Code of Maryland Regulations. However, because local
governments are required to implement these provisions locally, local zoning ordinances, subdivision regulations, codes, policies, plans, and guidance documents are used to facilitate effective implementation at the local level.

The commission is constantly working to streamline the critical area program and improve its effectiveness, so there may be regulations in effect that have not yet been incorporated into a county’s or town’s code or ordinance. There are also occasions where there may be conflicts between local provisions and state regulations. In these instances, the more restrictive provisions usually apply.
