CSX is taking significant precautions to maintain a safe, secure project environment throughout reconstruction of the Virginia Avenue Tunnel. As part of these precautions, experts applied Federal and District standards to conduct rigorous modeling and testing to identify potential construction impacts and then develop plans to offset disruptions, such as noise, vibration and air quality. Throughout construction, we will use a comprehensive monitoring program to make sure those plans are effective and, if needed, we will adjust our approach to ensure the necessary mitigation measures are in place to address unforeseen conditions.
Prior to the start of construction the project team performed air, noise and vibration monitoring to establish a baseline and used the data to develop construction plans. Pre-construction monitoring reports are available here.
Monitoring devices are installed in the community to record vibration, noise and air-quality conditions. Environmental experts will analyze the data collected and issue monthly reports that summarize the monitoring data. The reports will contain the monitoring data and explain exceedances of project standards as well as the actions taken to address those exceedances.
The District Department of Transportation (DDOT) is overseeing the construction process to ensure that the appropriate noise, vibration and air-quality mitigations are carried out. The public can report noise, vibration and air-quality concerns here or call our office at (800) 494-1049.
