In accordance with the City’s Municipal Separate Storm Sewer System (MS4) Permit, Cambridge is developing a Phosphorus Control Plan to address stormwater runoff to the Charles River. As part of the City’s stormwater program, Cambridge is working to reduce its current phosphorus loads to the Charles River through a combination of non-structural controls, like street cleaning, and structural controls, like tree box filters and rain gardens. Phase 1 of this plan must achieve the first 25% of the City’s phosphorus load reduction requirement by June 30, 2028.
The draft Phosphorus Control Plan is available for public review and comment. A factsheet is also available, which summarizes the impact of excess phosphorus in water bodies and key elements of the City’s plan. Comments on the draft Phosphorus Control Plan may be emailed to stormwater@cambridgema.gov by September 22.
