“This is something we foresaw because there are several low spots along these berms and levees,” said [Fraser] Shilling, whose report, Rising Above the Tide, says sea levels have already risen 8 inches along the California coast.
Persistently swamped Highway 37 — historically a sore spot for motorists — is rapidly becoming one of the Bay Area’s most pressing issues as heavy storms keep rolling through this winter, forcing repeated closures of a crucial transportation link.
The peculiar highway, which looks more like a rural farm road in places, connects the North Bay to the East Bay by cutting through wetlands and hay fields along the northern shore of San Pablo Bay. Wine Country day-trippers use it, as do drivers headed to Sonoma Raceway and Six Flags Discovery Kingdom in Vallejo.
The increasingly popular artery, which was shut down for much of last week, has been closed for about three weeks this winter because of flooding.
The soggy blockages have raised aggravation levels among tens of thousands of commuters who use Highway 37 each day, and are providing a disturbing glimpse into what ecologists say is a wetter future, in which floodwaters powered by climate change could permanently drown the roadway.
“It is definitely the most problematic area in the Bay Area from the point of view of shoreline flooding and threats to communities and infrastructure,” said Fraser Shilling, co-director of the Road Ecology Center at UC Davis and author of a 2016 report analyzing the future of the highway.
