State Route 37 Sears Point to Mare Island Improvement Project
Document Type
SIR - Supplemental EIR
Received
Present Land Use
State Right-of-way, Wildlife Refuge
Document Description
The purpose of the Project is to address reoccurring congestion on SR 37 in Sonoma, Napa, and Solano counties where the highway narrows to one lane in each direction between SR 121 and Mare Island (04-SON-SR 37 [PM 2.4/6.2]; 04-SOL-SR 37 [PM 0.0/8.5]; 04-SON-121 [PM 0.0/0.2]. This Draft Supplemental Environmental Impact Report is intended to supplement the 2023 EIR/EA/FONSI by providing information to address Project changes. These proposed changes include additional highway improvements and the enhancement of degraded marsh habitat at Strip Marsh East, which will be performed as a nature-based solution to minimize SR 37’s vulnerability to flooding in the near-term and to minimize project impacts on wetlands, waters, and special-status species habitats.
