    Sonoma County Transportation Authority 2009 Comprehensive Transportation Plan EIR

    Sonoma County Transportation Authority

    The 2009 Comprehensive Transportation Plan (CTP) updates past transportation planning priorities and provides a guide to multi-modal transportation investments over the next 25 years.  PMC prepared the EIR (which included a detailed analysis of greenhouse gas emissions and energy use) as well as required noticing and CEQA Findings.  PMC environmental staff also provided key testimony for public hearings on environmental issues.   

    The 2009 CTP updates past transportation planning priorities and provides a guide to multi-modal transportation investments over the next 25 years.  The goals of the CTP are to (1) maintain the system, (2) relieve congestion, (3) reduce emissions, and (4) plan for safety and health.  The CTP is a financially constrained plan that looks at the growth projections for the region and prioritizes projects and programs that can reduce existing and future congestion.  As such, the 2009 CTP includes: 

    • Highway Capital Improvements.  Seven capital improvements listed in the Measure M Strategic Plan and projects funded from other sources, mostly focused on carpool lane improvements on the U.S. 101 freeway corridor.
    • Local Road Improvements.  Dozens of local road improvements listed in the Measure M Strategic Plan and also funded from other sources are included.  These often focus on road widening or signalizing of intersections.
    • Transit Improvements.  These include investments in the Measure M Strategic Plan and the Sonoma-Marin Area Rail Transit (SMART) passenger rail project. 
    • Non-Motorized Transportation Improvements.  Projects in the 2008 Countywide Bicycle and Pedestrian Master Plan are included.  This includes independent bike trails (Class I), striped bike lanes (Class II), and bike routes (Class III).
    • Additional Improvements.  This includes funding for maintenance of local streets, traffic safety and safe routes for schools, local projects funded through developer-related Transit Impact Fees, right-of-way and dedication improvements by developers.
    • Regional Operations Programs.  The CTP includes ongoing, financially constrained regional operations programs administered by the Metropolitan Transportation Commission (MTC).  Funding for these programs is included in MTC’s Draft Transportation 2035 Plan.
    • Land Use and Pricing Assumptions.  The CTP is designed to provide transportation infrastructure that accommodates the projected growth of Sonoma County and the larger region.  The socioeconomic forecasts used in the CTP are based on the Association of Bay Area Governments’ (ABAG) Projections 2005 with adjustments based on local forecasts and the release of its Projections 2007.  ABAG population and employment forecasts were used as control totals for jurisdictions and county planning areas.  Sub-allocation of control totals to traffic analysis zones within jurisdiction boundaries or county planning areas was based on local planning agencies and SCTA staff.
