Supplemental Draft Environmental Impact Statement for D2 Subway

d2subwaysdeiscover image


The Federal Transit Administration (FTA), with Dallas Area Rapid Transit (DART) as the local project sponsor, has prepared the Supplemental Draft Environmental Impact Statement (SDEIS) for the Dallas CBD Second Light Rail Alignment (D2 Subway). You can view the SDEIS below. The SDEIS includes several appendices, such as the 20% Preliminary Engineering design plans.

Copies of the SDEIS are also available for public viewing at the Dallas Public Library, 1515 Young St, Dallas, TX 75201. Library hours may be affected by COVID-19 restrictions. Please contact DART Community Engagement at 214-749-2543 to make arrangements for viewing a hard copy if needed.

Comments


The 45-day public comment period for the SDEIS was from May 15, 2020, through June 29, 2020. Comments received during the 45-day review period are being classified and recorded into appropriate subject areas. All comments will be reviewed and documented. However, only substantive comments will receive responses and be documented in the Final EIS/Record of Decision.

While the official SDEIS comment period has closed, you are still welcome to submit comments to [email protected]; however, they will not be documented in the Final EIS/Record of Decision.

Public Hearing Audio and Transcripts


In order to ensure the safety and well-being of our customers and employees, DART conducted virtual call-in public hearings on Thursday, June 11 from 12:00-1:00 p.m. and 6:30-7:30 p.m. The purpose of the hearings was to collect verbal public comments on the D2 Subway SDEIS.

DART also conducted an in-person Public Hearing following COVID-19 safety protocols and practices on June 25, 2020, 12:00 to 1:00 p.m. at DART Headquarters. The written transcript is included below:
