The interactive maps below provide information on Maryland's environment, including land, air, water, and how the public can use Maryland's unique resources.
Coast Smart Climate Ready Action Boundary (CS-CRAB) MapThe Coast Smart Climate Ready Action Boundary (CS-CRAB) was developed in a multi-agency effort by the Maryland Coast Smart Council to identify and mitigate future flood risk to the state's existing infrastructure. The data product was created leveraging existing FEMA regulatory boundaries and infusing an additional three feet of water elevation to determine the new water surface elevations and potential flooding extents (up and out).
Floodplain managers will note that this is very similar to the Federal Flood Risk Management Standard (FFRMS) for Federal projects established by President Obama in 2015, rescinded by President Trump in 2017, and recently reestablished by President Biden in January 21, 2020.

Stormwater StoryState and federal law requires large urban jurisdictions to control stormwater pollution to the maximum extent practicable (MEP). Stormwater best management practices (BMPs) temporarily store and treat stormwater runoff to stop flooding and reduce pollution entering waterways. This story map is an educational tool to educate and promote an understanding of stormwater management efforts across the State of Maryland. It highlights how BMPs can improve the health of the waters and the health of a community. Examples include BMPs that are successfully implemented and those that do not meet project goals to show how future applications can be improved to be more functional.

Water Quality Assessments Integrated Report and TMDLsThis map displays surface water quality assessment information found in Maryland's 2016 Integrated Report of Surface Water Quality (IR) and is underlain by the watershed for which Total Maximum Daily Load (TMDL) analyses have been approved by EPA (for each respective pollutant). Surface water quality assessments and TMDL analyses have been completed for a variety of water body types including: impoundments, rivers, and estuarine waters.
Total Maximum Daily Load (TMDL) Watershed MapsThis map displays additional information resources related to the TMDL implementation process and Maryland's watershed delination. Additional data downloads and information regarding TMDL can be found at the TMDL Data Center.
Maryland Land Restoration ProgramThe Land Restoration Program (LRP) of the Maryland Department of the Environment provides financial incentive for the redevelopment of brownfields, which are sites that either qualify for the Voluntary Cleanup Program or are contaminated by oil. Redevelopment of these sites will help revitalize industrial and commercial areas. LRP also administers the 'Superfund' program for the State of Maryland that assesses suspected hazardous water sites, including federal facilities, to control and remove environmental and public health threats through site cleanups and remedial actions.
