Stormwater (Drainage)

Did you know that it is illegal to drain chlorinated pool water into the road and the public drainage system?  That water will eventually makes its way to our streams, rivers, and ponds.  Pool water should be dechlorinated before it enters the natural environment, and the pH should also be within an acceptable range.  Ideally, pool water should be slowly discharged into your yard where it can be absorbed into the ground.

Building Resilient Infrastructure and Communities (BRIC) Grant
Stream Crossings and Culvert Assessment

The Town of Hopkinton is working with a team of consultants to assess areas of concern in the Town’s stormwater collection and distribution system. As part of the FEMA Building Resilient Infrastructure and Communities (BRIC) grant, the Town is tasked with identifying different areas of localized flooding in order to enhance the Town’s existing stormwater collection infrastructure and reduce flooding-related impacts to the community. The primary focus of this work will be on stream crossings and culverts.   

The Town applied for this grant in 2020 following the completion of the 2020 Hazard Mitigation- Municipal Vulnerability Preparedness Plan (HMP-MVP Plan). The HMP-MVP Plan identified that stormwater flooding is a component of two of the four main hazards affecting the Town. The full HMP-MVP Plan is linked below.  

The Department of Public Works is now seeking input from Town residents and business/property owners about their experiences with flooding in order to better inform the FEMA BRIC Grant effort.     

Public Survey - Stormwater Flooding 
Residents and business/property owners are encouraged to complete this survey to share details about flooding in their neighborhood, and to encourage their neighbors to complete the survey as well.   

SURVEY CLOSED
