Project Overview

The District of Columbia Department of Transportation (DDOT) and the Federal Highway Administration (FHWA) are proposing rehabilitation of 1.5 miles Broad Branch Road, NW between Linnean Avenue and Beach Drive. Prior to moving the project through final design and construction, Draft and Final Environmental Assessments of the proposed action and its potential impacts have been prepared in accordance with the National Environmental Policy Act of 1969 (NEPA), the Council of Environmental Quality (CEQ) regulations (40 CFR 1500-1508), and the FHWA's Environmental Impact and Related Procedures (23 CFR 771). FHWA is the lead federal agency for the project with the National Park Service (NPS) as a cooperating agency. DDOT in conjunction with the FHWA, and in cooperation with the NPS, has released the Final Environmental Assessment (EA) and the Finding of No Significant Impact (FONSI) for the proposed action.

The purpose of the proposed action is to rehabilitate Broad Branch Road to satisfy operational and safety needs and done so in a manner keeping with the setting of the project area. Context sensitive solutions took into account the adjoining land uses - residential developments and wooded areas to the west and Rock Creek Park to the east. The proposed action will improve roadway and drainage infrastructure conditions, enhance safety operations for vehicles, bicyclists and pedestrians, improve intersections and provide ADA-compliant sidewalks for the entire length of the corridor.

DDOT and FHWA published an Environmental Assessment (EA) on October 21, 2013. The EA presented the operational benefits and environmental effects of three Candidate Build Alternatives. A public hearing on the findings of the EA was held on November 5, 2013.

Following publication of the initial EA, DDOT worked closely with the National Park Service and the U.S. State Department to minimize potential encroachments by the project on Rock Creek Park and Embassy lands owned and occupied by Sovereign Nations. As a result of these extended coordination efforts, DDOT developed a modified version of Candidate Alternative 3 (as presented in the initial EA) which avoided all encroachments to Embassy properties and further minimized encroachments on Rock Creek Park.

Recognizing the extended period of time since the initial EA was published, DDOT and FHWA prepared a Revised Draft Environmental Assessment. The revised draft expanded upon discussions presented in the initial EA published in October 2013 and included the new Alternative 3 Modified. The revised draft was issued for public review on October 15, 2020 by the FHWA and comments were accepted for 30 days. In order to reduce the risk for COVID-19, a complete digital copy of the Revised Draft EA as well as a narrated video presentation were placed on the project website in lieu of public meetings. Comments were accepted on the project website.

After review and consideration of comments received on the Revised Draft EA, Build Alternative 3 Modified was identified as the Preferred Alternative (PA) in the Final EA. The selection of the PA was based on the improved roadway, stormwater and drainage infrastructure while minimizing impacts to the natural environments and adjoining properties owned by the Federal government and several Sovereign Nations. In doing so, the PA best meets the purpose and need of the project. The PA would provide two 10-foot wide travel lanes, standard curb and gutter, ADA-compliant sidewalks, new drainage infrastructure, and replacement of the Soapstone Creek culvert.

The release of the Final EA and FONSI completes the NEPA process for this project.
