Overlay zones and other site criteria are used to determine if additional regulations, approvals or permits are required. For example, a site that is located in a Specific Plan or Community Plan Implementation Overlay zone may have different or additional requirements than the base zone.

A site within any environmentally sensitive lands layers would require additional information be submitted with any permit application in order staff to confirm the presence of environmentally sensitive lands that could require a Site Development Permit or Neighborhood Development Permit.
