LYNN – Mayor Judith Flanagan Kennedy ordered on-street local parking limited to one side, beginning Tuesday, in an effort to keep traffic flowing on streets gradually shrinking under a steady onslaught of snow.The order – punishable by ticketing and towing – restricts parking to the even-numbered side on streets where parking is normally allowed on both sides of the street. Even-side parking will not apply to streets across the city where signs already limit parking to one side of the street.The order’s objective, said Kennedy and city Public Works Commissioner Andrew Hall, is to keep streets cleared for plows and emergency vehicles as well as daily traffic flow.”We know that by ordering this we eliminate 50 percent of the parking in the city, but we can’t compare the snowfall of recent days to anything, really, in history,” Kennedy said, adding, “People have to be mindful that if they are impeding traffic, they will be ticketed and towed,” she said.Three major snowfalls since Jan. 26 have already resulted in nearly 1,500 tickets issued during declared snow emergencies and more than 600 cars towed. In ordering one-side parking, Kennedy stressed the city faces a public safety challenge in keeping streets open to traffic.She said help is on the way or already in force to aid the city in burrowing out from under the snow mounds. City officials received state permission Monday to dump snow in ocean water off the Lynnway and Kennedy is confident state officials will send heavy snow removal equipment to Lynn.”Governor Baker understands coastal communities have been hard hit,” she said.Ward 3 City Councilor Darren Cyr and fellow councilors, including Councilor at large Gordon “Buzzy” Barton, praised city Public Works crews for snow clearing efforts. But Cyr said dozens of dead-end terraces, courts and other small local streets are snow-clogged and need to be plowed out.He gave Noyes Terrace and Summit Avenue residents credit for looking after older neighbors like Summit Avenue resident Joan Garfield, who lives in a home at the end of a steep, winding, one-lane street.”It’s a lot of snow but I love it here in the summer with the breeze and the ocean view,” Garfield said.Hall helped plow out Summit Avenue on Tuesday, with applause from Cyr.”He’s a general who gets involved right on the front lines,” Cyr said.Hall stressed during a Tuesday night meeting with councilors that the even-side parking restriction has one goal: “We want to ensure parked vehicles are not obstacles to plows and public safety vehicles.”With Kennedy warning another foot of snow could fall locally over the next several days, councilors and city officials urged residents to continue shoveling sidewalks and digging out fire hydrants.
