The City of Falls Church declared a snow emergency effective 11 a.m. Tuesday, pursuant to the city's emergency operations plan. The snow emergency is effective until further notice is issued, so residents must remove parked cars from snow emergency routes. The no parking requirement will be enforced by the City of Falls Church Police Department on designated snow emergency routes. Officials say these routes are essential transportation corridors and must remain clear in order to allow snow removal crews to clear the roads. Residents are also encouraged wherever possible to not park cars on any streets so snow plows have unheeded passage.Traffic signs identify which city streets are snow emergency routes. Vehicles abandoned or parked on snow emergency routes may be towed and fined. The traffic emergency routes are available on the city's website at www.fallschurchva.gov/SnowRoutes.
