In addition to the Maryland Southern Railroad, various natural features
such as Glade Creek, border the property. The site contains non-tidal
wetlands, which have been delineated and surveyed. Hydric soils,
hydrology, and hydrophytic vegetation are all found indicating the
presence of wetlands.
The jurisdictional wetland definition is based upon the Federal Manual
January 10, 1989. Definition summary includes the Corps of Engineers
(CE), Environmental Protection Agency (EPA), and Soils Conservation
Service (SCS). Wetland definitions include only areas that are vegetated
under normal circumstances, while the Fish and Wildlife (FWS)
definition encompasses both vegetated and non-vegetated areas. Except
for the FWS inclusion of non-vegetated areas as wetlands, all 4
wetland definitions are conceptually the same. They all include 3
basic elements – hydrology, vegetation, and soils - for identifying
Areas included are inundated or saturated by surface or ground water at a
frequency and duration sufficient to support a prevalence of vegetation
typically adapted for life in saturated soil conditions. Wetlands
generally include swamps, marshes, bogs, and similar areas.
Although the bulk of this area is generally closed to the public,
