    Description

    Polygon features that represent the political boundaries of Metropolitan Planning Organizations (MPO) that exist in Maryland and for which the Maryland Department of Transportation (MDOT) is a member. In several instances, these MPO boundaries extend beyond Maryland’s borders into neighboring states as well as the District of Columbia. MPO Boundaries’ data includes information on each boundary's name, geographic location, and the total size / extent of each area. MPO Boundaries data was intended to be used for planning purposes within governments at the National and State level. Maryland's MPO Boundaries data is a sub-set of the U.S. Department of Transportation (USDOT) Office of the Assistant Secretary for Research and Technology's Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). A metropolitan planning organization (MPO) is a federally-mandated and federally-funded transportation policy-making organization that is made up of representatives from local governments and governmental transportation authorities. Federal law requires the formation of an MPO for any urbanized area (UZA) with a population greater than 50,000. Federal funding for transportation projects and programs are channeled through this planning process. Congress created MPOs to ensure that existing and future expenditures of federal funds for transportation projects and programs are based on a continuing, cooperative, and comprehensive (“3‑C”) planning process. MPOs are charged with developing a 20-year long-range transportation plan (LRTP) and a short-term (usually 2-6 years) program called the transportation improvement program (TIP) for each of their respective regions. The seven MPOs of which Maryland jurisdictions and agencies are members are listed below. The Maryland member jurisdictions are listed under each MPO (note that some MPOs cover multi-State regions). The Maryland Department of Transportation is a member of each of the MPOs listed. Each of the listed member jurisdictions has a different level of involvement with its MPO.Maryland's MPOs are as follows: National Capital Region Transportation Planning Board (TPB)https://www.mwcog.org/tpb/- Charles County, Maryland- Frederick County, Maryland- Montgomery County, Maryland- Prince George's County, Maryland- City of Bowie, Maryland- City of College Park, Maryland- City of Frederick, Maryland- City of Gaithersburg, Maryland- City of Greenbelt, Maryland- City of Laurel, Maryland- City of Rockville, Maryland- City of Takoma Park, Maryland- Maryland Department of Transportation (MDOT)Baltimore Regional Transportation Board (BRTB)https://baltometro.org/- Anne Arundel County, Maryland- Baltimore County, Maryland- Carroll County, Maryland- Harford County, Maryland- Howard County, Maryland- Queen Anne's County, Maryland- City of Annapolis, Maryland- City of Baltimore, Maryland- Maryland Department of Transportation (MDOT)Cumberland Area Metropolitan Planning Organization (CAMPO)https://alleganygov.org/473/Metropolitan-Planning-Organization- Allegany County, Maryland- City of Cumberland, Maryland- City of Frostburg, Maryland- Maryland Department of Transportation (MDOT)Hagerstown / Eastern Panhandle Metropolitan Planning Organization (HEPMPO)https://www.hepmpo.net/- Washington County, Maryland- City of Hagerstown, Maryland- Maryland Department of Transportation (MDOT)Wilmington Area Planning Council (WILMAPCO)https://www.wilmapco.org/- Cecil County, Maryland- Maryland Department of Transportation (MDOT)Salisbury / Wicomico Metropolitan Planning Organization (S / WMPO)https://www.swmpo.org/- Wicomico County, Maryland- City of Fruitland, Maryland- City of Salisbury, Maryland- Town of Delmar, Maryland- Maryland Department of Transportation (MDOT)Calvert-St. Mary’s Metropolitan Planning Organization (C - SMMPO)https://www.calvert-stmarysmpo.com/- Calvert County, Maryland- St. Mary's County, Maryland- Maryland Department of Transportation (MDOT)Maryland's MPO Boundaries data is owned and maintained by the Transportation Secretary's Office (TSO) of the Maryland Department of Transportation (MDOT). Being a subset of the USDOT's NTAD, an annual update of Maryland's MPO Boundaries data is performed by TSO in close coordination with each MPO, the Maryland Department of Transportation State Highway Administration (MDOT SHA) and the Federal Highway Administration (FHWA). MPO Boundaries data is a strategic resource for the USDOT, FHWA, MDOT, as well as many other Federal, State, and local government agencies. Maryland's MPO Boundaries data is updated on an annual basis.

    Description

    State of Maryland municipality boundary dataset.Maryland Department of Planning (MDP) maps annexations from municipalities. This dataset is created and maintained by the Maryland Department of Planning. These boundaries are not intended to serve as a legal description. Fields:MUN_NAME (Municipality Name): Name of Municipality located in Maryland.RESOLUTION_NUMBER (Resolution Number): Local Municipality Annexation Resolution Number.ANNEXATION_DATE (Annexation Date) (DD/MM/YYYY): The Annexation Date field shows when there's been a change in the boundary. This date is known as the “Effective Date” from the municipality. The date 1/1/1997 is used as a default date of when annexation changes were first indicated in the GIS layer and not necessarily of when it was actually annexed. If there's a date of 1/1/1997, it can be assumed that the annexation occurred on this date or before. For example, for Baltimore City, the city boundary was determined hundreds of years ago. Other than that default date, the date will show when the property was annexed. ACRES (GIS Acres): GIS calculated acresJURSCODE (Jurisdiction Code) – Four letter county code: ALLE (Allegany), ANNE (Anne Arundel), BACI (Baltimore City), BACO (Baltimore County), CALV (Calvert), CARO (Caroline), CARR (Carroll), CECI (Cecil), CHAR (Charles), DORC (Dorchester), FRED (Frederick), GARR (Garrett), HARF (Harford), HOWA (Howard), KENT (Kent), MONT (Montgomery), PRIN (Prince George’s) QUEE (Queen Anne’s), SOME (Somerset), STMA (St. Mary’s), TALB (Talbot), WASH (Washington), WICO (Wicomico), WORC (Worcester).

    Description

    Esri ArcGIS Online (AGOL) Map Image Layer for accessing the Maryland Coast Smart - Climate Ready Action Boundary (CRAB) Inundated Zones data product.Maryland Coast Smart - Climate Ready Action Boundary (CRAB) Inundated Zones consists of polygon geometric features which represent the geographic areas throughout the State of Maryland that are impacted by CRAB inundation (0 to 1ft, 1 to 2ft, and 2ft or more).The Maryland Coast Smart - Climate Ready Action Boundary (CRAB) Inundated Zones data product was created using a GIS spatial analysis model, unique for each county in the State of Maryland. Coastal counties follow an analysis methodology that incorporates FEMA Stillwater wave action as it is understood from the FEMA identified VE zones. A Water Surface Elevation (WSE) and Still Water Elevation (SWEL) rasters are used as the baseline to identify existing water depths within each county. For all flood zones that are not classified as VE the WSE three feet was added to reflect a three-foot rise in the base flood elevations. For those WSEs falling within a FEMA floodplain identified V Zone, six feet was added (three feet for the increase in flood elevations for the CS-CRAB, and 3 feet to compensate for the minimum of 3 foot wave action typically mapped by FEMA) / wave heights greater than 3 feet were reduced to the 3 foot minimum for consistency across the shoreline. The newly calculated WSE plus three datasets were then converted to points and merged. Next, an Inverse Distance Weighted (IDW) Interpolation was used to compute the proportional weighted values between the WSE point locations based on proximity. The DEM for each county is then subtracted from the new IDW raster in order to show precise water locations as they relate to the land elevation, producing a freeboard depth grid representing the depth of flood waters above the existing ground elevation given a 3 foot increase in water level. A course resolution QAQC was applied to remove “islands” of data associated with DEM inaccuracies and other elevation anomalies. The analysis was run at a1 ft x 1 ft raster resolution. The DEM accuracy for each county varies based what is currently available. Here the breakdown of DEM accuracy for each county used in this project: Anne Arundel County DEM year is 2017 and horizontal resolution is 1ft. Baltimore County DEM year is 2015 and horizontal resolution is 2.5ft. Baltimore City DEM year is 2015 and horizontal resolution is 0.7m. Calvert County DEM year is 2017 and horizontal resolution is 1ft. Caroline County DEM year is 2013 and horizontal resolution is 3.125ft. Cecil county DEM year is 2013 and horizontal resolution is 0.6m. Charles County DEM year is 2014 and horizontal resolution is 0.9m. Dorchester County DEM year is 2013 and horizontal resolution is 0.9m. Harford County DEM is 2013 and horizontal accuracy is 1.5m. Kent County DEM year is 2015 and horizontal resolution is 0.7m. Prince George’s County DEM year is 2014 and horizontal resolution is 0.7m. Queen Anne’s County DEM year is 2013 and horizontal resolution is 0.6m. Somerset County DEM year is 2012 and horizontal accuracy is 1m. St Mary’s County DEM year is 2014 and Horizontal accuracy is 0.9m. Talbot County DEM year is 2015 and Horizontal accuracy is 0.7m. Wicomico County DEM year is 2012 and horizontal accuracy is 1m. Worchester County DEM year is 2011 and horizontal accuracy is 1m.The Maryland Coast Smart - Climate Ready Action Boundary (CRAB) Inundated Zones data product was created by the Maryland Environmental Service (MES) in partnership with the Maryland Department of Environment (MDE) and the Coast Smart Council, under the guidance of the Maryland Department of Natural Resource (DNR).For additional information, contact MDOT SHA OIT Enterprise Information Services:Email: GIS@mdot.maryland.gov
