Caltrans and the Metropolitan Transportation Commission will host a public meeting on Tuesday, from 6 to 7:30 p.m. in Vallejo to discuss the Draft Supplemental Environment Impact Report for the project concerning Highway 37.
The public meeting will focus on proposed changes to the project since the original environmental document was approved in 2023, including additional highway improvements and the enhancement of degraded marsh habitat at Strip Marsh East, which is adjacent to SR 37 near Mare Island.
The Draft SEIR and Preliminary 4(f) De Minimis Determination can be found online at: https://dot.ca.gov/caltrans-near-me/district-4/d4-popular-links/d4-environmental-docs
The public review and comment period for the Draft SEIR ends February 3.
Many projects are going into improving Highway 37 in the future, although the Interim Project, which would add an extra lane, including a toll lane, won’t begin for at least a year or two. Another project, the Ultimate Project, not only concerns adding a lane, but also elevating lanes to deal with sea level rising.
Highway 37 improvements have been in the works for the last few years, as it was announced in 2023 that the Metropolitan Transportation Commission will receive $20 million from the Department of Transportation’s Federal Highway Administration for a 10.4 mile section of the highway, which spans Solano, Napa, Sonoma and Marin counties. The money will go to improve corridor resilience and prevent flooding impacts.
