Public hears plans to assess sea level rise

It may not be a matter of if but when, and how to plan for it, when it comes to coastal Maine and sea level rise over the coming decades. And Stonington is one waterfront town that is not chancing a wait-and-see approach.

A recent $60,000 Maine Coastal Program Grant from the Maine Department of Agriculture, Conservation and Forestry has funded a study by GEI Consultants to assess where and how badly a rise of one, two, four or as much as nine or 10 feet could affect the town’s infrastructure.

“It’s a way to hone in on the particular things that are critical for Stonington and come up with a solution,” said GEI engineer Leila Pike to about 20 concerned citizens and town officials at a March 5 public meeting at town hall.

According to a 2017 National Oceanic and Atmospheric Administration study, the mean sea level will rise from a low projection of 1.5 feet to an extreme of 11 feet by the year 2100.

Pike’s presentation showed how the study will assess flood risks to critical town infrastructure and ways to adapt in the short-, medium- and long-term, based on 30-year, 50-year and 80-year projections. Areas deemed sensitive to flooding include Main Street, with its pumping stations, Hagen Dock and fire department, Moose Island, Burnt Cove, Oceanville Road and Airport Road. The fish pier is the subject of a separate, grant-funded study and will “probably” be raised two or three feet, Pike said.

“2100 is 80 years from now. How can we plan for that?” asked resident Hilton Turner.

“We can plan for more storms and worse storms, and see what we can do,” Stonington Economic Development Director Henry Teverow said. “There’s so much uncertainty with sea level rise, so [we should] monitor it and have different adaptive procedures in place.”

Pike said GEI will consult with the public works department on determining what elevation of flooding might damage a structure, and the study will highlight incremental adaptations, rather than plan for extremes. For example, short-term adaptation for a road covered with water during a storm could be placing signs or flashing lights, while a long-term adaptation could be raising the road itself.

“It’s not going to help us to stick our head in the sand and pretend nothing is going to happen,” Town Manager Kathleen Billings said. “[We need to be] vigilant and proactive rather than let the next ones after us deal with it.”

Towards that end, voters approved $25,000 for a Sea Level Rise Reserve Fund at town meeting March 9, that can serve as the town match for future grants.

Once the vulnerabilities assessment is completed, GEI will hold a second public meeting to go over the results before designing adaptive measures, to be presented at a subsequent meeting.

“There are a lot of places in the world where the towns just disappeared,” she said.
