No Major Flood Damage Reported at Reston North Park & Ride

Floodwaters at the Reston North Park and Ride have receded, leaving little damage at the site where water pooled up to the windshields’ of cars yesterday (July 8).

A spokesperson for the Virginia Department of Transportation told Reston Now that there appears to be no damage to the pavement or drains, which were simply overwhelmed with the “massive amount of water.”

“We’re focusing on other areas,” Ellen Kamilakis said. “There are other heavily devastated areas in the county.”

Crews are currently on-site throughout the county to assess damages.

In early September 2011, floodwaters caused major damage at the Reston Park and Ride. Several vehicles were damaged during that storm.

The lot is located at the corner of Sunset Hills Road and Wiehle Avenue.
