What is mandatory, is the city's snow-shoveling law:
Snow must be removed from sidewalks, steps, driveways, parking spaces and similar paved areas for public use (including access ramps and curbs) within 48 hours after a snowfall of three to 10 inches and within 72 hours after a snowfall of more than 10 inches. When clearing paved areas, provide a safe, unobstructed, passable path 36 inches wide.
Residents are asked to avoid driving during the storm, if possible. If you have a non-emergency weather-related issue to report to city police, call 240-314-8900. For emergencies, obviously, call 911.
Maryland Gov. Martin O'Malley has declared a snow emergency for the state, as well.
