Restore Habitat at Magazine Beach in Cambridge

Magazine Beach Volunteers

CRWA is working with state and local government, community groups, and volunteers to restore wildlife habitat at Magazine Beach and improve water quality in the Charles River. Join us at one of our upcoming volunteer events to remove invasive plants along the bank of the Charles River. 

Wednesday, September 13th | 1:30 pm - 4:30 pm 

Friday, September 15th | 2:00 pm - 5:30 pm 

Sign up

At these events, we will be digging invasive common reed and purple loosestrife out of the basins near the ball fields so that these areas can be planted with attractive grasses, flowers, and shrubs that will clean rainwater before it enters the Charles and provide bird habitat. Volunteers should wear rain or work boots as the ground can get wet. We will provide tools and gloves, but feel free to bring your own if you have them. We will meet at Magazine Beach at the baseball diamond. Feel free to join us for as much of the afternoon as you can.

Green Streets in Watertown and Allston 


A green street uses porous surfaces, plantings, trees and other nature-based elements to reduce polluted stormwater while beautifying the neighborhood and improving walking, cycling, and driving experiences. CRWA is currently collaborating on green streets in Watertown, Boston, and Cambridge. 

In Boston, CRWA is working with the Boston Planning & Development Agency and other partners to make Coolidge Road in North Allston a green street. As the design phase begins, we want to hear from you! Please join us at an open house on Monday, September 11, 5:00pm-7:00pm at the Honan-Allston Library. Feel free to drop in for as much or as little time as you would like.

CRWA is working with the Town of Watertown to make Edenfield Avenue the first green street in Watertown. Learn more about this and other Watertown green infrastructure projects on September 14th at 6pm at the Watertown Town Hall.
