SAVE THE ALEWIFE BROOK

Save the Alewife Brook is a growing grassroots environmental group with supporters in Cambridge, Arlington, Somerville, Belmont, and Medford. We are working to address flooding and water quality problems in the Alewife Brook.

We are especially concerned with the Combined Sewer Outfalls, which discharge sewage water into the Alewife Brook during many storm events. During major flood events, sewage contaminated water from the Alewife Brook flows into the homes, yards, and parks of the area’s most diverse and vulnerable neighborhoods, which are considered Environmental Justice Populations. To make matters worse, the Alewife reverses direction during some flood events, sending that contaminated floodwater back to North Cambridge and Belmont, towards their most diverse and vulnerable neighborhoods.

A review of FEMA flood maps reveals there are an estimated 1200 East Arlington residents, 3500 Cantabrigians, and 300 Belmont residents living in the Little River – Alewife Reservation’s 100-year flood plain. This does not count the 643 residents living in the Belmont Uplands/Silver Maple Forest housing complex, who would be surrounded by hazardous sewage-contaminated flood water in the event of a 100-year flood. Climate Change threatens to exacerbate the problem, with wetter rain seasons, more frequent and more severe storms, and sea level rise.

Climate Change makes the sewage discharge problem exponentially worse.

The hope for the communities around the Alewife is improvement of brook water quality and adaptation to the effects of climate change through regional resiliency strategies.
