The city’s offices will reopen Friday and a snow emergency parking ban will end after a Thursday nor’easter dumped an estimated 14.6 inches, exceeding National Weather Service predictions and giving Cambridge and surrounding communities a total of 31.4 inches so far this winter.

Update on Feb. 12, 2017: The official snowfall estimate for the day from National Weather Service was only 14.1 inches.

That beats last year’s total of 25.4 inches, but comes nowhere near – so far – the “snowpocalypse” of 2014 and its 110.6 inches.

City offices and services, schools and libraries will be open at their normal hours, and the street parking ban ends at 7 a.m. Friday, with city officials warning that towing will go on until then. Residents parked in a snow emergency garage should leave by 9 a.m. to avoid being charged. Residents parked at the 52 Oxford Garage must exit within 2 hours of the ban being lifted.

Property owners are reminded that ice needs to be removed within six hours from the time it forms, by city law. Snow needs to be removed within 12 hours after it stops falling during the day, and before 1 p.m. if it snowed during the night.

Eighth-graders at the Cambridge Street Upper School are shoveling snow to raise money for their June class trip to New York City and for community service credi, parents reminded the community. Shoveling can be requested by email here or here.

The city offered some reminders to property owners about shoveling:

Please maintain a minimum of 36 inches clear width, so that people who use wheelchairs and other mobility devices (also parents using strollers, etc.) can navigate the sidewalk. The Cambridge Commission for Persons with Disabilities requests that a 48-inch clear width be created when possible – this gives an extra measure of safety. Additionally, CCPD urges residents and businesses to pay particular attention to the corners, where one sidewalk meets another – shovel the full length and width of curb ramps, so that pedestrians with disabilities can get to the crosswalks. Business owners are requested, if there is a disability parking space on the street near your storefront, to please take the extra time to shovel a clear path to that space, so that your customers with disabilities can visit your establishment. In particular, shovel a space wide enough so that vans with lifts can deploy the lift onto the sidewalk.

The city recognizes the effort that goes into shoveling out any vehicle parked on a city street during a snow event. However, residents may not use objects such as trash/recycling barrels, furniture items or any other item to save parking spots on public streets. These items will be treated as trash and disposed of by DPW.
