Wetland Hydrology. Wetland hydrology is defined as inundation or saturation in the upper 12 inches of the soil for at least five percent of the growing season in most years (Environmental Laboratory 1987). The growing season in the project area is approximately 260 days based on “frost-free days (NRCS 2012a, Soil Conservation Service 1977). Five percent of the growing season is approximately 13 days. Factors that influence hydrology include precipitation, topography, soil permeability, and plant cover. Primary indicators of wetland hydrology include inundation or saturation in the upper 12 inches, drift lines, sediment deposits, and drainage patterns. Secondary indicators include oxidized rhizospheres, water-stained leaves, local soil survey data, and the FAC-neutral test of the vegetation.  Hydrophytic Vegetation: Jurisdictional wetlands are typically dominated by hydrophytic plant species (e.g. more than 50 percent of the dominant plant species have an indicator status of facultative [FAC], facultative wetland [FACW], or obligate wetland [OBL]) (Xxxx 1988). Hydrophytic vegetation is “the sum total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present,” as defined by the Corps (Environmental Laboratory 1987). Pairs of wetland and upland data points were recorded at representative locations in each of the wetland types in the Project Study Area, and the wetland boundaries were extrapolated based upon similar variations in vegetation, hydrology, and topography. The boundaries of all waters, including wetlands, were mapped in the field onto 1:2,400 scale aerial photographs of the Project Study Area provided by Microsoft Corporation’s Bing maps. All potential boundaries within the Project Study Area were mapped. The locations of all data points and the wetland boundaries were mapped using a Xxxxxxx Xxx-XT Global Positioning System (GPS) receiver. All GPS data were differentially corrected to achieve a horizontal accuracy of 1 to 3 meters. Mapped boundaries were digitized and projected onto current 1:2,400 (1 inch equals 200 feet) aerial photograph maps. Copies of the delineation data forms and photographs of representative locations are provided in Appendices A and B. The delineation map is provided as Figure 5.

Related to Wetland Hydrology

  • Wetlands or “wetland” means an area that is inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances does support, a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as hydrophytic vegetation.

  • Wetland or "wetlands" means areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands do not include those artificial wetlands intentionally created from nonwetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. Wetlands may include those artificial wetlands intentionally created from nonwetland areas created to mitigate conversion of wetlands.

  • Wildlife habitat means a surface water of the state used by plants and animals not considered as pathogens, vectors for pathogens or intermediate hosts for pathogens for humans or domesticated livestock and plants.

  • Sediment means solid material, mineral or organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water or gravity as a product of erosion.
