Waterside Drive - Road safety Improvements
The document officially adopts the National Park Service's Preferred Alternative -- Alternative 4: Add Merge Lane by Widening the Road Toward the Median -- for implementation. The selected alternative will allow for improvements to traffic flow and will minimize the number of vehicle accidents along the Parkway in the vicinity of Waterside Drive, NW using a combination of roadway improvements, including a new acceleration lane along the Parkway and traffic calming measures. The selected alternative will also permanently stabilize both banks of Rock Creek to address the severe erosion that has occurred and will mitigate for impacts to the riparian areas along the stream bank of Rock Creek near Waterside Drive, NW that resulted from previous construction.
The EA for this project was prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, as amended, and implementing regulations, 40 CFR 1500-1508, and NPS Director's Order #12 and Handbook, Conservation Planning, Environmental Impact Analysis, and Decision-making (DO-12). Compliance with Section 106 of the National Historic Preservation Act of 1966 is being completed with this NEPA process, and the associated Assessment of Effect is detailed in the EA.
The National Park Service has released a Finding of No Significant Impact for the Reconstruction and Rehabilitation of Rock Creek and Potomac Parkway Southbound at Waterside Drive, NW.
