Environmental Coordination Mapping

Environmental mapping supports the environmental coordination process during the development of the long-range transportation plan. The maps in this gallery offer a way to compare the region’s long range transportation plan with state conservation plans as well as natural and historic resource inventories and plans.

Green Infrastructure

The Green Infrastructure data is based on the GreenPrint program established in 2001 by the State of Maryland with the purpose of protecting the remaining ecologically-valuable land in the state. Green infrastructure consists of hubs and corridors. Hubs contain ecologically-valuable lands, corridors connect the hubs and provide important wildlife passages, help with seed and pollen transport, and protect stream valleys and wetlands.

Chesapeake Bay and Atlantic Coastal Bays Critical Area

Chesapeake Bay Critical Area, established by the 1984 Critical Area Act, includes all lands within 1,000 feet of the Bay for protection. The Critical Area within the Baltimore region is contained within five of the seven jurisdictions: Anne Arundel, Baltimore, Harford and Queen Anne’s Counties as well as Baltimore City.

Impaired Watersheds

Map displays watersheds with information on whether or not they are impaired for nutrients and/or sediment pollution. This information is based on assessment data in Maryland’s 2016 Final Draft Integrated Report of Surface Water Quality. For more information on water quality impairments in the watersheds, visit the Maryland Department of Environment's website.

Historic Resources

Map shows where important historic places in Maryland are located. It references both the Maryland Inventory of Historic Properties and the National Register of Historic Places.

Locations of archaeological resources are protected under the Freedom of Information Act and are, therefore, not included.

Land Use/Land Cover

Land/use land cover data developed by the Maryland Department of Planning using aerial photography, satellite imagery, and parcel data.

Protected Lands

Map shows Maryland Department of Planning and Maryland Department of Natural Resources Protected Lands. They include:

  • Maryland Agricultural Land Preservation Foundation Easements
  • Rural Legacy Areas and Properties
  • Maryland Environmental Trust Easements
  • MDP Protected Lands
  • DNR Lands
  • County Owned Properties
  • Federal Lands, and
  • Private Conservation Properties

Sea Level Rise

Maps display Mean High High Water (MHHW) in 2050 and 2100. Data developed for Maryland State Highway Administration and planners as they endeavor to mitigate or prevent the impacts of sea level change. Rates of sea level change calculated using the US Army Corps of Engineers Intermediate Curve.

Sensitive Species Project Review Areas

These areas primarily contain rare, threatened, or endangered species. Included are Habitat Protection Areas, Nontidal Wetlands of Special State Concern, Natural Heritage Areas, and Colonial Waterbird Sites.

Wetlands of Special State Concern

Wetlands identified as WSSC (those with rare, threatened or endangered species and those with unique habitat values) receive certain protections under State regulations. One of the protections is a 100 foot buffer from development.
