Public forum on protecting Hwy. 37 from flooding

The public is invited to an informational meeting about options for improving Highway 37, which is threatened with sea-level rise, flooding and increased traffic between Vallejo and Novato.

There will be four sessions in surrounding counties, including a meeting Wednesday, Sept. 27, from 6 to 8 p.m. at the American Canyon Council Chambers, 4381 Broadway St.

The public will learn about planning options, including a toll for motorists, and will be able to voice opinions.

Highway 37 runs for 21 miles through the Napa-Sonoma marshes. The estimated costs to elevate the road on a levee or causeway range from $1 billion to $3.4 billion in 2022 dollars.

In July, the Napa Valley Transportation Authority heard from a planner who said a $6 toll could pay for a $1 billion project, a $7 toll could pay for a $2.6 billion project.

Caltrans is working with the counties of Napa, Solano, Sonoma and Marin on plans.

Additional meetings include one on Oct. 2 at the Vallejo Naval and Historical Museum, 734 Marin St., Vallejo and one Sept. 28 at the Sonoma Veterans Memorial Building, 126 First St. West, Sonoma. Both meetings are from 6 to 8 p.m.
