The Post’s Mike DeBonis reports that the District plans to declare a snow emergency at 6:30 p.m. Wednesday.

The declaration, which restricts street parking on major city thoroughfares, will allow crews to more thoroughly plow streets, said William O. Howland, D.C. director of public works.

A snow emergency violation involves a $250 ticket plus towing and storage fees. This will be the first snow emergency declared in the city since 2010, Howland said.

See a Post map of the D.C. snow emergency routes. The District also posts signs along snow emergency routes. Use this link to see a listing of the snow emergency routes.

The Department of Public Works policy is to move towed vehicles to lots, rather than move them onto other streets in the neighborhood. The towing fee is $100 and the storage fee is $25, which will double after 48 hours and then increase by $25 every 24 hours after that.
