The following publicly available resources can help you get started, but keep in mind: determining exact critical area boundaries is typically a job for an environmental professional skilled at interpreting legal definitions and identifying the many critical area types and variations. If your proposed project will have impacts on critical areas, requires that your documentation is prepared by a qualified professional.
The earlier you identify your site’s existing conditions and the more accurately you document them in your application materials, the faster and potentially cheaper your permitting process will be.
