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 1,000 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 Mdimap 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 data set represents the Department of Natural Resources interpretation of the location and extent of the Critical Area; however, the digital maps are not recognized as the "official" maps. In accordance with Subsection 8-1807(a) of the Critical Area Act, the Critical Area consists of (1) All waters and lands under the Chesapeake Bay and its tributaries to the head of tide as indicated on the State wetland maps, and all State and private wetlands designated under Environment Article, Title 16, annotated Code of Maryland; (2) All land and water areas within 1,000 feet beyond the landward boundaries of State or private wetlands and the of tides designated under Environment Article, Article 16, Annotated Code of Maryland; and (3) Modification to these areas through inclusions or exclusions proposed by local jurisdictions and approved by Commission as specified in Natural Resources Article, Subsection 8-1807, annotated Code of Maryland. These maps are hard copy maps that cannot be exactly replicated in a digital format; therefore, some interpretation was necessary to create the digital line. Hard copy maps depicting the official Critical Area boundary line are available for review at the Chesapeake Bay Critical Area Commission, and at most local planning and zoning departments.

Enterprise Zones Focus Areas

The Maryland coastal zone is comprised of the land, water and subaqueous land between the territorial limits of Maryland in the Chesapeake Bay, Atlantic Coastal Bays and the Atlantic Ocean, as well as the towns, cities and counties that contain and help govern the thousands of miles of Maryland shoreline. The Maryland coastal zone extends from three miles out in the Atlantic Ocean to the inland boundaries of the 16 counties and Baltimore City that border the Atlantic Ocean, Chesapeake Bay and the Potomac River up to the District of Columbia. This area encompasses two-thirds of the State's land area and is home to almost 70% of Maryland's residents.The Department of Natural Resources makes no warranty, expressed or implied, as to the use or appropriateness of Spatial Data, and there are no warranties of merchantability or fitness for a particular purpose or use.

Abstract:

One-meter soil cores were taken to evaluate soil texture, bulk
density, carbon and nitrogen pools, microbial biomass carbon and
nitrogen content, microbial respiration, potential net nitrogen
mineralization, potential net nitrification and inorganic nitrogen
pools in 32 residential home lawns that differed by previous land
use and age, but had similar soil types. These were compared to
soils from 8 forested reference sites.


Purpose:


Soil cores were obtained from residential and forest sites in the
Baltimore, MD USA metropolitan area. The residential sites were
mostly within the Gwynns Falls Watershed (-76.012008W, -77.314183E,
39.724847N, 38.708367S and approximately 17 km2) Lawns on
residential sites were dominated by a variety of cool season
turfgrasses. Forest soil cores were taken from permanent forest
plots of the Baltimore Ecosystem Study (BES) LTER (Groffman et al.
2006). These remnant forests are over 100 years old with soils that
were comparable in type and texture to those underlying the
residential study sites. Soils from all sites were from the Manor
series (coarse-loamy, micaceous, mesic Typic Dystrudepts), which are
well-drained upland soils with loamy textures and bedrock at 5 to 10
feet below the soil surface.


To aid the site selection process we used neighborhoods in the
Baltimore City metropolitan area that have been mapped using
HERCULES, a high resolution land cover classification system
designed to assist in the study of human-ecological systems
(Cadenasso et al. 2007). Using HERCULES and additional data sources,
we identified residential sites that were similar except for single
factors that we hypothesized to be important predictors of ecosystem
dynamics. These factors included land use history (agriculture and
forest, n = 10 and n = 22), housing density (low and medium/high, n
= 9 and n = 23), and housing age (4 to 58 yrs old, n = 32). Housing
age was acquired from the Maryland Property View database. Prior
land use was determined based on land use change maps developed by
integrating aerial photos from 1938, 1957, 1971, and 1999 into a
geographic information system. Once a list of residential parcels
meeting the predefined criteria were identified, we sent mailings to
property owners chosen at random from each of the factor groups with
the goal of recruiting 40 property owners for a 3 year study (of
which this work is a part). We had recruited 32 property owners at
the time that soil cores were obtained.
