Boston Green Infrastructure Resident Survey đł
Thank you for your interest in climate resilience in Boston. The Boston Community-Based Flood Resilience and Green Infrastructure Planning Project is a collaborative initiative between the City of Boston's Office of Green Infrastructure, the city's 3 watershed associations - the Charles, Mystic, and Neponset River Watershed Associations - and many Boston community groups. The project aims to engage the public in collecting much-needed information about where they see flooding in Boston and how it is impacting them. This survey will be used to better understand how flooding is impacting residents and visitors and help plan future Green Stormwater Infrastructure (GSI) projects in Boston. This brief survey is designed to gather resident input on Green Stormwater Infrastructure across the City. We estimate this survey will take 5 mins to complete.
