The applicant seeks authorization to conduct grading and piping operations within waters of the United States to enclose an unnamed intermittent and ephemeral tributary of the Meramec River, for the purpose of a residential development. The project site is on an 8.6-acre tract comprised of woodlands within an upland topography. The site contains two drainages which bisect the site, flowing from northeast to southwest, located in between Hawkins Fuchs Road and Interstate 55, in the City of St. Louis, Missouri. Project impacts include the piping enclosure of an unnamed intermittent and ephemeral tributary, consisting of 910 lineal feet of channel. This will facilitate residential lots, road crossings, and storm water discharge points.
