13Keeping streets clean and open

The short version: A street sweeper or a snowplow can only clear what it can reach, so most of street cleaning is really the work of getting parked cars out of the way: posted sweeping days, snow emergency parking bans, tow trucks and alerts. In Boston, residential streets are swept by day from April through November and main roads are swept at night all year. When the city declares a snow emergency, cars must come off main roads or be towed. The famous Boston space saver is tolerated only during a declared snow emergency and for 48 hours after it ends, and never in the South End or Bay Village.

How it changed: from rivers of manure to uniformed sweepers

In the 1890s, New York's streets were covered in an estimated 2.5 million pounds (about 1,100 tonnes) of horse manure a day, plus 60,000 gallons (227,000 liters) of urine; dead horses were left in place and garbage lay a foot or two deep.²⁶⁵ (The widely repeated tale of an 1894 "Great Horse Manure Crisis" is a different matter: its famous quote has never been found and traces to a 2004 article, as Where your trash actually goes explains.²⁶⁶)

When sanitary engineer George E. Waring Jr. took over New York street cleaning in 1895, his first step was about the curb, not the broom: a law requiring horses and carts to be stabled overnight instead of left standing in the street.²⁶⁵ That is the same logic as a modern sweeping-day tow zone: the street has to be empty before it can be cleaned.

Waring's sweepers wore white uniforms and pith helmets and pushed wheeled carts, and the city held a parade honoring the department in 1896.²⁶⁵ Snow was handled the simple way: it was dumped in the rivers.²⁶⁵

The white uniforms earned the sweepers the nickname "White Wings."²⁶⁷

Why do cities tow cars for street sweeping?

A mechanical sweeper runs along the gutter, where litter, leaves, grit and sediment collect against the curb. A parked car blocks that strip completely, and the sweeper has to swing around it, leaving the dirt behind. That makes sweeping programs mostly parking programs: signs that name a day and time window, tickets for cars left in place, and tows for the worst cases.

Sweeping also matters below the street. What the sweeper does not pick up can wash into storm drains in the next rain, so a clean gutter is partly a stormwater measure. (More on stormwater in Where it goes after you flush (or it rains).)

In Boston: street sweeping rules

Boston runs two programs, according to the city's Public Works Department:²⁹³

Residents can sign up for No-Tow alerts through the city's Notify Boston system.²⁹³

If your car is towed, the city lists the costs as a $132 tow fee plus $35 a day in storage and a fuel surcharge, before any parking ticket.²⁹³

As of September 2026, Boston's parking clerk lists a $40 fine for a street cleaning violation and $90 for overnight street cleaning (no tow), with late penalties of $13 and $30.²⁹⁴

What is a snow emergency?

A snow emergency is a formal declaration by a city that changes the parking rules so plows can clear the main roads curb to curb. The details vary by city; what follows is Boston.

When Boston declares a snow emergency, cars parked on main roads are ticketed and towed.⁸² To give people somewhere to put their cars, the city arranges discounted garage parking from two hours before the declaration until two hours after it is lifted.⁸²

How does Boston plow and salt?

The Public Works Department runs plowing and salting. Under Mayor Marty Walsh, the city launched Boston Snow Stats, a public page showing the number of plows on duty, miles plowed, salt used and the percent of streets plowed, searchable by address.²⁹⁵

The scale is large: in one season, a Public Works update (undated on the city's site) reported more than 74,862 tons of salt applied and nearly 19,000 truckloads of snow removed.⁸³ Going into the 2024-25 winter, the city said it had 175 pieces of equipment ready to clear roads, could put 800 on the streets with contractors during a snow emergency, and had 34,000 tons of salt on hand.²⁹⁶ Removal is a separate job from plowing: plows push snow to the side, and in a big storm the banks themselves have to be scooped up and trucked away to keep lanes, crosswalks and hydrants open.

Many cities also spray roads with brine, a salt-water solution, before a storm so snow does not bond to the pavement.

Are space savers legal in Boston?

A space saver is an object, often a lawn chair, a traffic cone or a trash barrel, that a Boston resident puts in a parking spot they shoveled out, to claim it while the car is away. It is a neighborhood custom, not a property right. The city's rules, as of October 2026, are narrow:⁸²

• Only during a declared snow emergency. Space savers are allowed only while a snow emergency is in effect. A regular snowfall without a declaration does not count.
• 48 hours after it ends, they must go. Once the snow emergency is lifted, space savers must be removed within 48 hours.
• Never in the South End or Bay Village. Space savers are banned in both neighborhoods.

The rules have firmed up over time. An earlier city notice from the Walsh administration in 2015 described the 48-hour limit as "a guideline," and the South End ban at that time was a winter pilot.²⁹⁷ The same notice said Public Works crews remove space savers on trash day.²⁹⁷ The current city page states the 48-hour removal as a requirement and lists the South End and Bay Village bans.⁸²

In our reading, the gap between custom and rule is where neighbors clash. A chair still out a week after the emergency ends is outside what the city tolerates, whatever the block's custom says. The space saver is a short window the city allows, not a claim on public curb space.

Who clears the sidewalk?

Sidewalks and bins sit in the same strip of street as the gutter. Trash bags on the curb are both litter and rat food, which is why several cities are moving trash off the sidewalk and into sealed containers. In New York, more than 70% of trash had to be containerized as of late 2025, and Manhattan Community Board 9 in West Harlem became the first fully containerized district in June 2025.²⁹² In Boston, the July 2024 Rodent Action Plan piloted rodent-resistant cans on Boston Common, in parks and on North End streets.⁹⁵

Public litter bins matter too. Solar compacting bins from Bigbelly, a Needham, Massachusetts company, hold about five times a standard can and send a signal when full; Philadelphia used them to cut Center City collections from more than 30 a week to about six.²⁸⁹ Boston maintains its bins in-house, but the company's CEO said in 2023 that the city was not using the bins' fullness data.²⁸⁹

Boston requires property owners to clear sidewalks and curb ramps within three hours after snow stops falling, or within three hours after sunrise if it snowed overnight, leaving a path at least 42 inches wide.²⁹⁸ Fines for an uncleared sidewalk are $200 a day for commercial properties, $100 for residential buildings with more than 16 units and $50 for smaller ones; shoveling snow into the street is also prohibited and fined.²⁹⁸

What's changing now (2026)

• Bags off the curb. New York's containerization rollout continues, with Brooklyn Community Board 2 next to go fully containerized in 2026.²⁹² For street cleaning, the likely effect is fewer torn bags and less loose litter in the gutter.
• Data in public. Boston publishes live plowing statistics through Snow Stats and sends No-Tow alerts for sweeping through Notify Boston.²⁹⁵²⁹³
• Space saver rules are now stated as rules. The city's current snow page presents the 48-hour removal and the South End and Bay Village bans as requirements, not guidelines.⁸²
