PEPC and Parkplanning may experience intermittent outages from 8 PM MT to 12 AM MT between 5/29 - 5/31 due to database maintenance.


The District Department of Transportation (DDOT), along with the Federal Highway Administration (FHWA), and in cooperation with the National Park Service (NPS), prepared an Environmental Assessment (EA) to examine alternative actions and environmental impacts associated with the proposed project to provide transportation improvements at the intersection of Pennsylvania Avenue SE and Potomac Avenue SE, in Washington, DC. The Pennsylvania Avenue SE and Potomac Avenue SE intersection includes NPS property, which consists of the adjacent roadway medians and triangle parcels.

The proposed project includes transfers of NPS property to DDOT and DDOT right-of-way to the NPS. The net transfer will be approximately 11,920 square feet of property from the DDOT to NPS and approximately 11,541 square feet from the NPS to DDOT. The purpose of the Pennsylvania and Potomac Avenues SE Intersection Improvement Project is to improve safety for pedestrians, pedestrian connections to transit, and traffic circulation.

The EA was prepared in accordance with the National Environmental Policy Act of 1969 (NEPA), the regulations of the Council on Environmental Quality (CEQ) for implementing NEPA (40 Code of Federal Regulations [CFR] 1500-1508), FHWA Technical Advisory (T6640.8a), Section 106 of the National Historic Preservation Act (NHPA), and NPS Director's Order (DO) 12, Conservation Planning, Environmental Impact Analysis, and Decision-making. The statements and conclusions reached in this finding of no significant impact (FONSI) are based on documentation and analysis provided in the EA and associated decision file.
