Mason Run Stormwater Improvements NEPA
EMH&T provided a study of the Mason Run watershed to identify alternative improvements to address stormwater problems and water quality impairments attributed to flooding. The study was conducted in conjunction with the U.S. Army Corps of Engineers, Huntington District and encompassed 6 square miles of the Mason Run watershed, including the Columbus International Airport, the Defense Supply Center Columbus (DSCC) and significant urbanized areas within the City of Whitehall. Alternatives for improvements were presented to reduce the potential for stormwater inundation attributed to Mason Run that impacts public infrastructure and utilities, and the residential and commercial properties within the watershed. In conjunction with the analysis of stormwater improvements, the study provided a thorough review and documentation of environmental impacts associated with those improvements, in accordance with the provisions of the National Environmental Policy Act (NEPA). In fulfillment of the NEPA process, all facets of data gathering and field reconnaissance were provided by EMH&T staff, including cultural resources and the public involvement process.
