Citywide Drainage and Water Quality Master Plan

Support residents in replacing impermeable paving with permeable pavers wherever possible (sidewalks, parking, walkways, etc.)

Inclusion of rain bioretention and phytoremediation zones with new street updates.

With wonderful capital projects, such as the updating of Beacon St. to include bike lanes and wider sidewalks, we should ensure that green zones, as pictured here, serve efficiently as bioretention and phytoremediation zones. This is a perfect opportunity to collect stormwater runoff on a highly trafficked street. With a proper infiltration media, a shallow depression below street level, and a grate or cut-out in the curb would allow excess polluted stormwater to infiltrate into the water table rather than enter the drain-to-the-ocean pipeline. Additionally, when sidewalks are expanded (the brick zone, here) these areas could instead be planted with native grasses (grassed swales) to help mitigate nitrogen and other pollutant concentrations in the cities soils (in addition to serving as a bioretention zone). Moreover, incorporating these types of solutions also assist in preventing bike lanes from flooding during heavy rain events, increase community connection to nature, can help serve as "green corridors" for pollinating insects to traverse the city, and can help develop local smart growth initiatives (https://www.mass.gov/service-details/smart-growthsmart-energy-background-information)

Rain barrels and groundwater discharge

Incentivizing or requiring buildings to buffer their own roof-collected stormwater would reduce the amount of runoff going to city streets, and also conserve reservoir water for use during droughts. We recently installed two rain barrels to catch our garage runoff for use when watering plants. Rainwater from our house goes into a French drain instead of the street, so it waters our trees and bushes. The city should require this for new construction and subsidize re-routing to on-site buffer for existing properties, starting with those where it would help the most.

Eliminate CSO's don't just mitigate them.

Well past time to ensure we aren't dumping sewage in the river.

With flooding issue in our area (near the bike path at Clifton and Winslow), the city could establish rain gardens as green infrastructure
