WATERSHED RESOURCES REGISTRY

The Maryland Department of Transportation State Highway Administration (MDOT SHA) is part of a Technical Advisory Committee that developed the Watershed Resources Registry, an online GIS tool that identifies opportunities to protect, restore and conserve high quality resources and improve stormwater management.  The tool scores locations on a scale of one to five stars based on features that benefit restoration and preservation. Local, State and federal agencies, as well as other stakeholders, including the public, can use the interactive features to produce site maps that characterize and prioritize sites by project need. Potential uses include regulatory mitigation, restoration, enhancement, incorporation/consideration, avoidance and preservation.

The Technical Advisory Committee brings together 12 agencies whose contributions promote collaboration between environmental resource and regulatory programs through the Registry. All sites are scored by this committee, whose members represent the same agencies that review projects, and provide permits and environmental approvals. Using this application puts us "all on the same page" before coordinating at the project level.

The map below is an example of the Registry's output. It shows the output from the riparian preservation analysis model.  The deep red color represents the opportunity that would provide the most multi-resource benefits, “the most bang for your buck.”

In addition to showing analysis model outputs, the tool provides other data and site comparisons. You can find the best way to meet your needs while taking advantage of other watershed benefits at any given location.  The Registry illustrates mitigation sites for MDOT SHA planning studies and projects. MDOT SHA also uses the Registry to identify sites that support the Chesapeake Bay Total Maximum Daily Load.
