Redesigned East Boston park uses porous pavement to prevent pollution and flooding 

East Boston Central Park

Earlier this month, CRWA joined Mayor Martin Walsh and East Boston elected officials and community members to celebrate the grand reopening of Central Square and Bertulli Park in East Boston.

During the design process, CRWA worked with the Boston Transportation Department and a Neighborhood of Affordable Housing youth team to recommend green infrastructure that would prevent pollution and improve resiliency to climate change. The youth were tremendous advocates for the project and helped make it a reality. 

The redesigned park includes permeable pavement and pavers which filter stormwater runoff into the ground while preventing pollution from entering the Boston Harbor. Other improvements include 97 trees, fully accessible sidewalks and new benches. Projects like this one not only reduce pollution, but also help prevent flooding, increasingly important in a changing climate.

Watershed groups stand up for stormwater permit

Cyanobacteria in Charles River

When the the U.S. EPA finally issued the long overdue Massachusetts Municipal Stormwater General Permit (MS4 permit) in April 2016, CRWA concluded that it did not sufficiently protect rivers and streams. CRWA and Conservation Law Foundation appealed the permit and industry interest groups also appealed asserting that the permit was unlawful. These consolidated appeals are currently pending in the D.C. Circuit Court of Appeals. 

Meanwhile, just days before the permit was scheduled to take effect in July 2017, U.S. EPA, under Administrator Scott Pruitt, announced that it was delaying the permit for one year. In response, Massachusetts Rivers Alliance and nine watershed groups filed suit in federal district court last week, asking the court to vacate the EPA's one-year postponement of the permit and implement the permit immediately.  

The Massachusetts Municipal Stormwater Permit (MS4 permit), issued jointly by U.S. EPA and MassDEP under the Clean Water Act, is intended to reduce polluted stormwater runoff entering rivers and streams and requires municipalities to better manage this pollution. .
