One response is the design of a bridge over the Yantic River in Norwich.
Barry Ellison, public works director, says the $7 million project would replace two spans built more than 50 years ago.
The increased frequency of flooding is being considered in the six or seven designs being considered, he said.
The water has been up against the bottom of the bridge three times in the last 10 years, Ellison said.
Communities such as East Lyme, Old Lyme, Stonington borough and Waterford are starting to consider climate change in their decisions about future investments in projects such as culverts, pump stations and dune restoration, said Adam Whelchel, director of science at the Connecticut chapter of The Nature Conservancy
“But as far as hard-core projects, on-the-ground stuff, we’re still light on action,” he said. “We’re still in the planning phase.”
Most of the attention has so far focused on the hazards of intense storms, sea level rise and flooding, Whelchel said. Towns also need to focus on the threat of more frequent and prolonged heat waves and public health implications of climate change, such as higher pollen counts that exacerbate asthma and infestations of Asian tiger mosquitoes that carry West Nile virus, he said.
