Background
Noise Barrier C was originally planned to be located along the east side of Live Oak Drive from about 150 feet south of Green Oak Drive to about 50 feet south of Rivercrest Drive. This noise barrier was determined to be the best solution available to reduce roadway noise at nearby properties and the Potomac Heritage Trail.
In late May 2023 and June 2023, VDOT solicited the required votes and input from property owners most acoustically and visually benefitted by the barrier on whether to proceed with building Noise Barrier C. Eligible voters supported building Noise Barrier C. Input received from the supplemental surveys mailed to eligible properties, as well as feedback from a community meeting on June 21, 2023, also confirmed support for building Noise Barrier C.
Based on community engagement and input, modifications to Noise Barrier C were evaluated. VDOT and its project partners determined that Noise Barrier C from 7001 Green Oak Drive to 644 Live Oak Drive could be shifted from the original location farther away from Live Oak Drive toward I-495 and shortened at the northern terminus by approximately 300 feet. Noise Barrier C would still provide an adequate level of noise reduction at residential homes with these design changes in compliance with federal and state regulations. This shift would result in approximately 4 to 22 feet of space for future revegetation between Live Oak Drive and the noise barrier in this area. Additional analysis involving these changes can be found in detail in VDOT’s Final Noise Abatement Design Report Technical Memorandum for Noise Barrier C.
Latest Updates
In November 2023, VDOT reached out to the benefited receptors (property owners), as well as property owners most acoustically and visually affected by the barrier, to obtain input on the proposed modifications. The results indicate overall support for the changes, including 50 percent or more of the received surveys from the identified benefitted property owners voting in favor of the changes. Specific results are:
