Document Description
The California Department of Transportation (Caltrans) has prepared this Initial Study (IS) with Proposed Mitigated Negative Declaration (MND) for the State Route (SR) 12 Capital Preventive Maintenance (CAPM) Project in Sonoma County, California (the
Project). The Project proposes resurface the existing pavement on SR 12, including the shoulders, between Llano Road (Post Mile [PM] 11.0) and Farmers Lane (PM 17.4) from the outskirts of the City of Sebastopol to the City of Santa Rosa in Sonoma County. Additional work includes upgrading 4 curb ramps to meet American with Disabilities Act (ADA) standards, replacing up to 38 existing concrete approach slabs with 1.25 foot-thick new slabs, reconstructing drainage infrastructure, and upgrading up to 10,000 linear feet of the existing metal beam guardrail (MBGR) to Midwest Guardrail System (MGS), The shoulder of the connector between southbound U.S. Highway 101 (U.S. 101) and westbound SR 12 would be widened to approximately 10 feet and require the removal of approximately 7 to 10 landscaped trees. Along the eastbound SR 12 to southbound U.S. 101 connector, a 300-linear-foot drainage
system would be reconstructed on the outside shoulder from the end of the existing retaining wall to the existing sound wall. All work proposed would be within the Caltrans right of way (ROW).
