Cambridge runs from the river flats of Cambridgeport, filled and built up with two-families and triple-deckers between 1880 and 1920, to the low ground around Alewife Brook and Fresh Pond, where the streets flood when the brook backs up. In between are the brick rowhouses of Mid-Cambridge and the wood-frame houses on the higher ground near Harvard, most of them over fieldstone cellars with plaster walls and cast-iron plumbing.
Water finds these houses two ways. A hard rain fills the combined sewers under the older streets and pushes water up through basement drains in Cambridgeport and East Cambridge. Groundwater on the filled land rises with the river and comes through the cellar walls. And the same February cold snaps that split pipes in Boston do it here: the 2023 arctic blast and the long freeze of 2015 both left Cambridge basements and top-floor ceilings wet.
A cellar that floods every spring near Alewife is a sump pump failure cleanup job when the pump gives out. Water pumped out of a Cambridgeport basement still leaves wet paneling, joists, and a stone wall that need structural drying. A triple-decker with a burst supply line on the third floor is burst pipe water damage on every floor below it.
Cambridge is a city of renters and condo owners, and that shapes the loss. A unit that sat empty over winter break with the heat turned down is where a frozen pipe runs longest before anyone sees it. In a converted triple-decker, the water crosses three ownership lines on its way to the cellar, and the condo documents decide who pays for which floor. Photograph every unit that got wet, notify the association or the landlord in writing the same day, and keep the plumber's note about what failed.
Cambridge is one of the few cities in the region that runs its own water supply. The Cambridge Water Department draws from the Hobbs Brook and Stony Brook reservoirs and treats it at Fresh Pond, and it handles main breaks and meter problems on the street side. Rebuild permits for plaster, plumbing, and wiring go through the city's Inspectional Services Department.
