David has spearheaded efforts to reach functional-zero homelessness in San Mateo County by investing $55 million to build a first-of-its-kind Navigation Center to provide housing, job training and counseling for 240 individuals who are unhoused. The county has also purchased several hotels with state Homekey funding to shelter hundreds of more individuals and families facing homelessness including coastal farmworkers under David’s leadership.

David has championed the creation of more affordable housing as the county has invested nearly $350 million over the past decade to leverage nearly $2 billion in federal and state funding to produce 4,500 additional units of housing for older adults, veterans, foster youth, low-income families and single mothers from Daly City to East Palo Alto.

David, in his role on the Metropolitan Transportation Commission, helped secure federal funding under the Biden Administration’s Infrastructure Investment and Jobs Act to fund the full electrification of Caltrain, the South San Francisco/San Bruno Grade Separation and Burlingame Grade Separation projects. David also helped to secure an additional $112 million in federal American Rescue Plan Act funding to maintain operations at both Caltrain and SamTrans as ridership dipped dramatically during the pandemic.
