The dataset displays the presence and absence of forested areas within a 100 foot-buffer of a stream or waterbody. The National Hydrography Dataset (NHD) stream layer developed by the United States Geological Survey was buffered 100-feet on each side of the stream centerline to determine stream buffers in Maryland. A shoreline file developed by the Maryland State Highway Administration was buffered 100-feet to determine the shoreline buffer in Maryland. The resulting buffer layers were clipped with a forest cover layer to determine the presence and absence of forest in those buffers. The forest cover layer was derived from a tree canopy layer developed by the Community College of Baltimore County, Catonsville, Geography Department. The tree canopy was developed using 2007 National Agriculture Imagery Program (NAIP) color infra-red 1-meter imagery. To determine areas forested, contiguous areas of tree cover less than 1 acre were removed from the dataset and then used for clipping the stream and shoreline buffers.This is a MD iMAP hosted service.

The Comprehensive Zoning Map Process (CZMP) takes place every four years where any citizen may request a zoning change on any property in the County. The request for change is mapped as an issue. The County Council enacting legislation for each issue whether to retain the existing zoning or to enact a different zone(s) or district(s).

This feature class represents the petitioned sewer master plan areas that have been introduced in previous years through cycle amendments within Baltimore County. Unlike the SHisMasterPlan feature class, this feature class does not distinguish between different cycle amendment petitions and only reflects the most current sewer master plan designation.The sewer master plan geodatabase includes a feature data set (sewerMasterPlan) containing three feature classes: SCurMasterPlan, sewerCombined and SHisMasterPlan. The feature classes participate in a topology (tsewerMasterPlan). The SCurMasterPlan feature class represents the petitions for the current cycle. The sewerCombined represents the current master plan designation within the county. The SHisMasterPlan contains all of the petitions areas from all cycles. The geodatabase includes relationship classes that associate related table containing information on assessments, councilmanic districts, election districts, lineage (feature level metadata), plan map, recommendations and zoning designations.

Baltimore County's Urban Rural Demarcation Line (URDL) has divided the county into "urban" and "rural" areas since established by the Planning Board in 1967. Developed primarily as a growth management tool, it has influenced zoning, land-use, and infrustructure decisions, and was the baseline for the Baltimore County part of Maryland's Priority Funding Area. However, this boundary (digitized at a scale of 1:24,000 where 1" represents 2,000') was became obsolete as the county's GIS data increased in resolution (to 1:2,400 where 1" represents 200'). Until recently, determining a property's status as either urban or rural was of a highly interpretative nature. A new URDL was developed to more accurately match the 1:2,400 data (parcel, street centerline, zoning, etc). This version was reviewed and modified in a series of meetings with several interested county agencies. The new URDL removes much of the old one's ambiguity while keeping its original intent. The new URDL was reviewed, modified, and subsequently approved by the Planning Board on June 19, 2003. Minor revisions were effected 9/2/04, 10/21/04, 9/4/07, 5/21/09, 10/1/09 and 11/15/12. The URDL_poly feature class is one part of the URDL feature dataset.

This layer shows population, household, and employment forecasts at the TAZ level. Anne Arundel County data includes the City of Annapolis. Forecasts endorsed by the Baltimore Regional Transportation Board on July 28, 2020.The mission of the Cooperative Forecasting Group (CFG) is to develop a set of population, household, and employment control totals and small area forecasts to be used for transportation planning. The data set is utilized at BMC as an input to the travel demand model and for air quality conformity testing, and is available to federal, state, and local government agencies, as well as the general public. The local planning agencies that comprise the CFG are responsible for the development of the estimates and forecasts for their own jurisdictions. While methodologies vary between jurisdictions, the forecasts are generally based on local comprehensive plans, adopted zoning maps and regulations, and an inventory of residential holding capacity. The allocation of employment to the small area and its distribution across industry sectors is based largely upon an inventory of employers across the region.

New forecast rounds are developed on an as needed basis, but are generally triggered by the update of major planning documents by the local jurisdictions, significant unforeseen demographic shifts, and the availability of small area data. The members of the CFG have the opportunity to make annual updates to the cooperative forecasts to account for unexpected changes when a complete new “round” of forecasts is not warranted. For more information, see https://www.baltometro.org.

In 1984, the General Assembly enacted the Chesapeake Bay Critical Area Act to regulate development, manage land use and conserve natural resources on land in those areas designated as Critical Area. For this document, the Critical Area is all land and water areas within 1000 feet of the tidal waters' edge or from the landward edge of adjacent tidal wetlands and the lands under them. Georeferenced digital data files of the critical Area have been produced for Baltimore City and the 16 Maryland counties with land located within the Critical Area. The digital maps produced for each jurisdiction are polygons depicting the Critical Area and the land use classifications recognized by the Chesapeake Bay Critical Area Commission (CBCAC). Each jurisdiction is a separate file. The data were produced from hard copy parcel maps originally submitted by the counties as part of the requirements for developing their Critical Area Program. For the purpose of the MD iMap web service the Critical Area Data is displayed by two data layers, one general layer and one layer showing the available critical area data for local towns.This is a MD iMAP hosted service.
