Rosanne Foust, as the president and CEO of the San Mateo County Economic Development Association, promotes improvements in education, transportation, and housing, with involvement in the Grand Boulevard Initiative. This project aims to enhance transportation options along El Camino Real and create housing opportunities within a half-mile of the highway to reduce automobile dependency. The initiative encourages collaboration among local governments and stakeholders while maintaining community identities, serving as a model for integrating diverse needs into a consensus-driven approach.
