When the Jan. 4 blizzard hit Chelsea and Greater Boston, it was a lot of snow – which was par for the course in January – but the eye-opener was the 14.99 foot high tide that accompanied a storm surge.
Suddenly, blizzard conditions were matched with heavy flooding on Marginal Street, Congress Avenue and Beacham Street – where the Island End River actually went over its banks and threatened the New England Produce Center, which is a key cog in the region’s food supply.
To top it all off, the Chelsea Street Bridge was actually closed because the Creek was too high to keep it open.
“It really puts a lot of things into perspective,” said Roseann Bongiovanni of GreenRoots. “It’s predicted that all the way up to the Market Basket will be under water by 2030 and beyond, but you see something like the storm on Jan. 4 and it seems like it could be 2025 or 2020, maybe sooner…There are a lot of people who think they don’t have to worry about this now because the predictions are way off in the future. Well, the Chelsea Street Bridge closed down because the Creek overflowed. Nobody would believe that would happen in 2018, but it did. It’s real. That’s what I think we should take from this.”
City Manager Tom Ambrosino said there was some significant flooding in the Island End River area, coming up by Signature Breads, the marina and to the DPW Yard. However, the Produce Center didn’t have significant flooding. At the same time, it put into perspective that such a critical facility for the food supply in New England, some mid-Atlantic states and southern Canada could be in a very risky location.
“That was a scary situation,” he said. “I know it came up very close to our DPW yard.”
There are already several grants in hand to do some infrastructure work to shore up the Island End River (about $1.5 million in one grant), but Ambrosino and Bongiovanni said the storm on Jan. 4 puts an exclamation point on getting it done faster.
“That’s been one of our focuses at GreenRoots for quite some time because it is a very key facility for the region,” said Bongiovanni. “We have been working with the Produce Center and they say the bays are high enough that the produce won’t be compromised. We know they keep about three day worth of produce on hand, but what if the trucks can’t get there for three days or more. That Center provides all the produce for a large area, and that food supply would be cut off for as long as the flooding there persists.”
Bongiovanni said they have been working with the City on some ideas.
City Planners have suggested salt marsh restoration that could naturally prevent flooding, as well as new sea walls and green infrastructure.
A more ambitious project, Bongiovanni said, is a study to create a Micro-Grid in Chelsea that would be able to power places like the Produce Center and Beth Israel Medical on Broadway if the electrical supply were cut off.
“Besides sea level rise and flooding, we want to think about what would happen if the electrical grid were down and they couldn’t power their refrigeration units to keep the produce cold,” she said.
Partners in that upcoming study include the Produce Center, the City, Chelsea Public Schools, Chelsea Housing Authority and Beth Israel. They would all host renewable energy generators that could be used just for Chelsea in an emergency.
“It’s the first stages of making the City completely energy independent,” said Bongiovanni. “That’s the kind of thing we really need to start thinking about when we see water coming up as high as it did.”
