CITYBUS ZERO-
EMISSION BUS
ROLLOUT PLAN
as mandated by the
California Air Resources
Board
Zero-Emission Bus Rollout Plan Overview
• Required by California Air Resources Board for all
public transit operators
• Mandate for transition to zero emissions bus (ZEB)
fleets established in the Innovative Clean Transit (ICT) regulation
• Includes fixed-route buses and paratransit
cutaway vehicles
• Separately, FTA also requires grantees to adopt a
Zero-Emission Transition Plan
• Proposal: CityBus to transition its 29-bus fixed-
route fleet to battery-electric buses (BEB) by 2035

Summary
• Fixed-route fleet electrification required by 2040
• ZEB Rollout Plan must be approved by transit
agency governing body
• CityBus estimating full electrification of fixed-
route fleet by 2037, 3-years prior to ICT deadline
• $55M projected cost of initial full electrification
of fleet
• $22M in current grant awards
• Next steps:
• Seek Council approval of ZEB Rollout Plan
• Submit to CARB by June 30, 2023
• Update ZEB Rollout Plan as needed
• Continue to investigate electrification of
paratransit fleet
