Slope Stabilization Project - Georgetown University


The National Park Service (NPS) has prepared this Environmental Assessment (EA) in order to evaluate Georgetown University's (University) proposal to improve the integrity and scenic character of the slope supporting the University's West Perimeter Road. As proposed, all project improvements will occur on the University's property. However, by virtue of a Deed of
Easement dated September 15, 2003, the University conveyed to the United States certain scenic easement interests in a 2.5-acre wooded parcel within which the project is planned. The proposed project involves the following actions: demolition of a segment of the existing roadway, clearing the existing vegetation along an approximate 300-foot section of the supporting slope, removal of previously deposited unsuitable fill material along the disturbed portion of the slope, placement of new fill and engineered geo-textile fabric, installation of new storm water rainage system designed to channel run-off from the roadway to a new water quality dissipation device to be constructed at the base of the slope, re-contour the slope to better control storm water run-off, construction of new stone-faced retaining wall at the base of the slope, construction of a new segment of the roadway to include new curbing and catch basin, and implementation of a new landscape plan. This EA addresses the potential impacts associated with the Preferred Alternative (re-construction of a segment of the existing roadway and appurtenances), as well as, the impacts of the No-Action Alternative, in accordance with the National Environmental Policy Act of 1969, as amended (NEPA).
