Citywide Drainage and Water Quality Master Plan

The City developed a Citywide Drainage and Water Quality Master Plan, a collection of infrastructure projects that will reduce flooding, improve water quality, and mitigate combined sewer overflows. After years of modeling and evaluation, the Engineering Division and its consultants, with input from the pubic, have identified 22 projects that would address the root causes of flooding and prepare Somerville for climate change.

Christopher Gillover 1 year agoWith flooding issue in our area (near the bike path at Clifton and Winslow), the city could establish rain gardens as green infrastructure

Well past time to ensure we aren't dumping sewage in the river.
0 comment0Charlotte Tolonenover 1 year agoWould the city consider partnering with private property for mitigation?
We frequently have standing water at the end of Clifton Street, technically on private property and not included in existing green infrastructure projects, yet a great location for a subsurface trench given the topology. How can we partner to get infrastructure where it's needed, despite property lines?
2 comments3Charlotte Tolonenover 1 year agoBring back the rain barrel program? And community education?
We have been trying to wait patiently for a holistic stormwater solution and we still have years until that's likely to be completed. In the meantime can we educate the community about resources provided by the city (and bring back the defunct rain barrel program?) We must address the infrastructure, but should be layering the solution(s) at individual, neighborhood, and municipal levels.
0 comment1belandabout 1 year agoRain 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.
