Fort Necessity National Battlefield 2013 Wetland Study

Current geospatial features are based on previous 2013 field and post-field work. The following describes the original work and, therefore, applies to these re-created data: The Great Meadows wetlands data were the product of a delineation of wetlands and associated waterways subject to jurisdiction under Section 404 of the Clean Water Act and all wetlands subject to National Park Service (NPS) procedures for implementing Director’s Order #77–1: Wetland Protection within the Great Meadows Study Area was performed from June 10-14, 2013. This work utilized the U.S Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region as the primary methodology for making wetland determinations in the field. One palustrine emergent wetland separated into three cells encompassing (7.56 acres), and two riverine lower perennial/intermittent systems (e.g. Great Meadow Run and Indian Run) encompassing 0.65 acres of land were identified and delineated within the study area (Figure 2). The palustrine, emergent, persistent, habitat (PEM1) exhibited varying degrees of groundwater, floodflows, and past land use influences as evidenced by soil test pits and observations of the plant community throughout the site over the course of the investigation. Wetland-1 consisted of three cells separated by Great Meadows Run: W1 (5.29 acres), W1A (0.88 acres), and W1B (1.39 acres). None of the observed wetland ecosystems meet the PA Title 25, Chapter 105 Exceptional Value (EV) wetland designation standard. However, all of the identified and mapped palustrine wetland systems meet both the U.S. Army Corps of Engineers criteria and the Cowardin et al. (1979) definitions of wetland habitat and would fall under U.S. Army Corps, as well as, National Park Service jurisdiction.
