Municipal Vulnerability Preparedness Plan
In 2019, the City put together a Municipal Vulnerability Preparedness Plan, identifying 3 critical hazards that will be exacerbated by climate change: Extreme Heat, Urban Flooding, and Winter/Ice Storms.
This plan guides the City as it takes strategic action to build equitable climate resilience in these vulnerable areas.
Municipal Vulnerability Preparedness Plan
What is Resilience?
“Resilience” is a term often used in discussing climate change actions. Climate change resilience is the ability of a community to adapt and thrive in the face of extreme shocks and stresses. Resilient communities anticipate risks, plan to limit their impacts and adopt strategies that integrate all community systems – civic, environmental, social and economic – to mitigate and support recovery from extreme events while providing a good quality of life.
Environmental Justice in Worcester
The State of Massachusetts identifies an area as an Environmental Justice community if it has any of the following characteristics:
- The annual median household income is not more than 65% of the statewide annual median household income;
- Minorities comprise 40% or more of the population;
- 25% or more of households lack English language proficiency; or
- Minorities comprise 25% or more of the population and the annual median household income of the municipality in which the neighborhood is located does not exceed 150% of the statewide annual median household income.
Using these characteristics, the state government has designated approximately 92% of Worcester as an “environmental justice” community.
Urban heat can be dangerous. As temperatures climb, the most vulnerable members of our City can face serious health risks. In 2022, the City completed a Heat Risk Assessment which identified the most heat-vulnerable parts of Worcester.
Cooling the City
The 2022 Heat Risk Assessment resulted in recommendations to develop more reflective surfaces and to increase the total tree canopy across Worcester by 30,000 – 35,000 trees. Tree investments will be prioritized in areas with a higher vulnerability and all trees added by the City will be positioned to shade impervious surfaces like pavement.
Climate change impacts, such as extreme storm events with high precipitation, can result in increased stormwater runoff and flooding.
The City is working on a Drainage and Green Infrastructure Master Plan and undergoing stormwater system assessment and modeling, in order to identify opportunities for green infrastructure, as well as develop improvements to the stormwater system. Master Plan goals are:
- To develop a comprehensive understanding of the municipal drainage system and its constraints in conveying stormwater runoff during peak events.
- Identify the most vulnerable areas using infrastructure and social resilience framework.
- Prioritize actions to move toward a pipeline of near-ready projects that advance flooding resiliency, when funding allows, with a focus on a hybrid approach of nature-based solutions and grey infrastructure enhancements.
One of the best tools to combat flooding is Green Infrastructure: natural, sustainable projects that absorb stormwater and runoff, deflect heat, and even filter pollutants. Green Infrastructure is a new approach to development, contrasting traditional Gray Infrastructure, like underground pipes or concrete installments.
The Green Worcester Plan prioritizes Green Infrastructure development, and the City has already completed many installments. In 2018, the City redesigned the Senior Center parking lot and built a large rain garden and bioswale where heat-absorbing pavement once stood.
Growing Worcester's Tree Coverage
Planting more trees (and protecting existing ones) is one of the most effective actions we can take to help reduce climate change impacts.
The City of Worcester has established an Urban Forestry Tree Commission and also kicked off the development of the first Urban Forest Master Plan. The Plan will serve as a roadmap to proactively manage and grow the City's tree canopy and provide a shared vision for the future of the urban forest to inspire us to plant, care for, and protect our trees.
