The Business of Mobility: Transportation & Infrastructure in Sonoma County

Transportation and infrastructure decisions made today will shape Sonoma County’s economy, workforce mobility, and quality of life for decades to come. This program brings together senior regional leaders to provide a timely briefing on the transportation and public infrastructure projects currently underway—and those on the horizon.

Attendees will hear directly from

Dan Hennessey, Director of the Sonoma County Transportation & Public Works Department

James Cameron, Executive Director of the Sonoma County Transportation and Climate Authorities

Johannes Hoevertsz, Director of the Sonoma County Public Infrastructure Department.

Together, these leaders will share insights into project priorities, funding strategies, and long-range planning efforts, with a focus on how transportation and infrastructure investments support economic vitality, climate goals, and regional growth. Business leaders will gain a clearer understanding of what’s coming, what it means for employers and communities, and where opportunities exist for collaboration between the public and private sectors.
