WASHINGTON DC – New developments are expected Friday in the ongoing fight between DC leaders and food truck vendors.

A public hearing will look into the Mayor’s proposal to limit the amount of mobile food vendors serving the city.

The hearing is scheduled for later Friday morning. According to the online witness list, more than 50 people are expected to testify. Among the proposed regulation changes are limitations on where trucks can park—one of those places could be Union Station.

The proposal would limit the number of food trucks in many popular locations. Operators would have to take part in a monthly lottery to determine where they could park in 23 of the newly designated “mobile roadway vending zones.”

The problem? There are nearly 200 D.C. food trucks that offer fantastic food choices every day of every week.

Supporters of Mayor Vincent Gray’s plan say it will help alleviate parking problems—and protects brick-and-mortar restaurants.

Opponents say the plan would put several food truck operators out of business.
