Synthesizing Climate Vulnerability Assessments

Chelsea, Massachusetts

Featured image for the project, Synthesizing Climate Vulnerability Assessments


The City of Chelsea, MA, a northeast suburb of Boston, is at-risk to a variety of natural hazards – from flooding to the effects of rising heat. Most preeminent among them is vulnerability of many underserved areas of the city prone to flooding from the Mystic River, Chelsea Creek, and from marshy and riverine areas that have now been filled in, with expanses of the City’s sedimentation made up of poorly draining clay, peat, and fibrous soils. The city is now looking for a scientific partner to piece together the myriad studies on climate vulnerabilities in the city and develop a comprehensive strategy to analyze all the impacts holistically.


In recent years, Chelsea has been working with the Federal Emergency Management Agency (FEMA) to update flood protection maps of the area. Prior to the update, inundation was projected at only 50-100ft from the coast but now it extends to close to half of the community. This situation has been shocking but also helpful in pushing for greater climate change planning in the city. Thus far, climate change planning has been ad hoc.


Chelsea is very much an urban community with an official population of about 35,000 (unofficially 45k). It is a community that has always been a gateway city – one in which successive waves of immigrants have located, become Americanized, and moved on.  The City is still mainly comprised of immigrants: approximately 63% of the population is of Hispanic origin, and there is a growing East African population.  There are over 100 languages spoken in the Chelsea school system.


Chelsea team meets local Environmental Justice organization and gears up for summer public meeting

In the Chelsea-TEX team has made strong strides towards completing a overall climate vulnerability assessment. They have been able to meet with most stakeholders in the community and have only two remaining meetings. The highlight of their stakeholder meetings was meeting with Chelsea GreenRoots, a local environmental justice group. Chelsea GreenRoots does a lot of environmental work in Chelsea around environmental justice and air quality. In the past, the city has worked with them to do local climate preparedness planning. Through this meeting, the team learned that there is more climate awareness in community, therefore, it’s a good time to engage them.


By next month, the team will have met with the remaining stakeholder groups and be ready to schedule their first public meeting (TBD in late June/early July) to discuss preliminary work with the community.


Since Asha Sharma has recently obtained a summer data science fellowship, the team has pushed their revised final project completion date to late August 2017.
