Manchester-by-the-Sea is a small community on Manchester Harbor north of Boston. As the community is only 10 feet above sea-level, the town recognizes its wastewater treatment facility is at risk from sea level rise. To move beyond risk identification, the facility’s operators needed to determine the magnitude of its vulnerability to the changing climate. A vulnerability assessment can be an in-depth and daunting task for any size community. However, USEPA’s Climate Resilience Evaluation and Awareness Tool (CREAT) enabled Manchester-by-the-Sea to assess its region’s projected climate risks and its facility’s vulnerability to inundation from sea level rise. Using CREAT, the facility was able to evaluate potential climate-related impacts such as projected impacts to source water, receiving waters and other environmental concerns of its stakeholders. CREAT also facilitated the utility’s consideration of potential adaptation strategies for reinforcing the facility in anticipation of projected sea level rise. Recognizing sea level rise and increased precipitation threatens more than just the facility itself, the town applied for and was awarded a Coastal Zone Management Grant. This grant, awarded in December 2014, is helping the town assess climate risk and vulnerability to stormwater management in the city. Together, these vulnerability assessments will help the city select and implement adaptation actions to where they are most needed.
Description of the video:
We're in Manchester-by-the-Sea, Massachusetts. We're about 20 miles northeast of Boston on the coast and we're a community of about just under 6,000 people. Manchester's location of its sewer plant is kind of unique. It's right on the ocean, that also means it's only about 10 feet above sea level. It's 18 years old. It's approaching its 20-year design life. We're just beginning to see the true effects of climate change. This parking lot that is adjacent to the sewer plant currently will flood during storms. Four to six inches of water is not uncommon. I think one of our biggest motivations to try to get ahead of impacts from climate change is really a financial concern. So, to anticipate that is going to be less costly than to try to repair in a crisis situation. Well, we had a wonderful opportunity to participate in the EPA effort with the CREAT model. And then as we started working with the model, making decisions, plugging in the factors, and we saw the impacts on the community, that for me was a real wakeup call. So we've got to start making those decisions with an eye toward the future. And so it really drew us to conclude that we need to better fortify the area around the plant in order to keep it functioning. That means a higher revetment for seawalls, and looking at ways to divert water and disperse the water before it becomes concentrated and a problem in our critical areas. So I think that's you know sort of the beauty of CREAT It makes you assess what you're doing now, but then stretches you to think about the future. We approached this project thinking 'oh, well we've got a lot of years to plan for changes.' It turns out we don't. It's good that Manchester's thinking that way, thinking proactively. I think we're more than one step ahead with the data and the information that came out of CREAT. We have an opportunity to glimpse what the future may hold, but we are also given an opportunity to change that.
