Environmental Coordination Mapping

Environmental Coordination Mapping for Long Range Transportation Planning

The maps provided in the map gallery below offer a way to compare the region’s long range transportation plan with state conservation plans and maps as well as natural and historic resource inventories and plans. These maps were originally created for use in development of Plan It 2035, approved by the BRTB on November 14, 2011. In some cases, mapping data will be modified as updates are available through the resource agencies. Numbered lines on some of the maps denote specific projects in Plan It 2035, as indicated on the Plan It 2035 Highway and Transit Project List. Please note that the lines indicating a plan project do not represent actual planned alignment, as this is determined through project-specific planning.

Green Infrastructure

Green Infrastructure (2001)

The Green Infrastructure data layer was created 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, while corridors connect the hubs and provide important wildlife passages, help with seed and pollen transport, and protect stream valleys and wetlands. Relatively large percentages of green infrastructure exist in Anne Arundel, Baltimore, and Harford Counties.

Chesapeake Bay and Atlantic Coastal Bays Critical Area (2001)

Chesapeake Bay Critical Area was established by the 1984 Critical Area Act and includes all lands within 1,000 feet of the Bay. To protect the natural habitats within the Critical Area, as well as to protect the quality of the Bay, the Chesapeake Critical Area Commission supervises the creation and implementation of local Critical Area Plans. The Critical Area within the Baltimore region is contained within four of the six jurisdictions: Anne Arundel, Baltimore, and Harford Counties as well as Baltimore City.

 Impaired Watershed Thumbnail

Impaired Watersheds (2014)

This map displays watersheds within the Baltimore region, along with information on whether or not they are impaired for nutrients and/or sediment pollution. This information is based upon assessment data in Maryland’s 2012 Final Draft Integrated Report of Surface Water Quality. For further information on water quality impairments in each of these watersheds, visit  http://www.mde.state.md.us/programs/Water/TMDL/Integrated303dReports/Pages/ImpairmentMaps.aspx

Section 303(d) of the federal Clean Water Act requires states to identify water bodies that do not meet water quality standards. If they do not meet water quality standards, a Total Maximum Daily Load (TMDL) may be required.

 

Historic Resources (2014)

This map shows were important historic places in Maryland are located. It references both the Maryland Inventory of Historic Properties (2010) and the National Register of Historic Places (2011)

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

 

Land Use / Land Cover (2010)

This set of 2010 land/use land cover data was developed by the Maryland Department of Planning using aerial photography, satellite imagery, and parcel data.

 

Protected Lands and Greenways (2014)

This map shows Maryland Department of Natural Resources (DNR) Protected Lands and Greenways. They include:

Maryland Agricultural Land Preservation Foundation Districts (2013)
Rural Legacy Areas (2014)
Maryland Environmental Trust Easements (2013)
Forest Legacy Easements (2013)
DNR Lands (2013)
County Parks (2013)
Federal Lands (2014), and
Private Conservation Properties (2014)

Greenways (2002) are natural corridors of land that connect open spaces. Maryland’s Greenways consist of ecological as well as recreational greenways which are protected and managed to provide for certain functions such as natural resource conservation, recreation, alternative transportation, and habitat protection.

 

Sea Level Rise Maps (2014)

These maps display the maximum daily high tide in 2050 and 2100 in the Baltimore region. Maps were developed for the jurisdictions in the region that border the Chesapeake Bay. The mapping data used in these maps was developed to support the planners and leadership of the Maryland State Highway Administration (MDSHA) as they endeavor to mitigate or prevent the infrastructure impacts of sea-level change resulting from land surface subsidence and rising sea levels. Sea level change was determined for each county, using tidal reference station data (from 1992 to current), calibrating water elevations observed at tidal stations with land elevations, and correcting for glacial isostatic adjustment and land subsidence. The rates of predicted sea level change in the MDSHA study were deemed by experts to be neither conservative nor alarmist, and represent scientific best practices.

Sea Level Rise in Annapolis
Sea Level Rise in Anne Arundel County
Sea Level Rise in Southern Anne Arundel County
Sea Level Rise in the City of Baltimore and Northern Anne Arundel County
Sea Level Rise in Baltimore City
Sea Level Rise in Baltimore County
Sea Level Rise in Harford County

Sensitive Species map

Sensitive Species Project Review Areas (2010)

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

Wetlands of Special State Concern map

Wetlands of Special State Concern (WSSC) (1999)

Wetlands identified as WSSC in Maryland (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.
