PURCHASE SCHEDULE ASSUMPTIONS
• Vehicles are replaced at the end of their
planned service life
• Overdue replacements are spread over the
first 4 years of the transition
• EVs are purchased if a feasible AND suitable
model is available
• Cap of $10M annually, not adjusted for
inflation
Replacements Costs
• EV cost reference current market prices
• EVs that are not commercially available are assumed to be 2.5x the price of their fossil fuel counterparts in 2025 • Costs projected to the future based on International
Council on Clean Transportation studies (graph below)

ACF COMPLIANCE REALIZATION CHALLENGES
Mismatch between vehicles that CARB
considers available as an EV and those that
Santa Rosa may consider suitable as an EV.
1 CARB Exempt Vehicles List
5 Santa Rosa considers ¾, 1,
1.5-ton EV pickups not
available in 2025 since they
aren’t commercially sold
CARB granted categorical exemption
to very few vehicle types
Class 1, Off-Road, Construction Vehicles
Class 2B-8 Vehicles
CARB considers those EVs
available because EV van
chassis can be upfit with
pickup truck body styles.

POLICY STUDY OVERVIEW
• Planning and Economic Development (PED) seeks recommendations on encouraging private-led EV charger deployment in the public right of way. • Santa Rosa’sGeneral Plan 2050 and GHG Reduction Strategy include objectives and measures for increased public EV charging.
• NV5 and Santa Rosa interviewed:
- EV charger companies (It’s Electric, Voltpost)
- City of Santa Rosa (Planning, Parking)
- City of San Francisco (SF DPW, SF Environment, SFMTA) - City of Alameda
It’s Electric EV Charging Station
NV5.COM | Delivering Solutions — Improving Lives
POLICY STUDY OVERVIEW - RECOMMENDATIONS
1. Impact/Development Fees
- Develop Capital Investment Plan for a city-wide
deployment of EV chargers
- Collect development fees to fund the program
- Determine priority locations (charging deserts)
2. Facilitate Private Agreements for EV
Charger Providers
- Establish permitting pathways for private
companies to partner with property owners to
install EV chargers on curbside
- Update regulations to allow installations
3. Develop a Public EV Charging Task Force

MAIN FINDINGS OF FLEET ELECTRIFICATION STUDY
1. Fleet Electrification costs $38 million from 2025 to 2040 over business as usual.
2. Near-term compliance with ACF is difficult due to vehicle availability and cost.
3. City should pursue all exemptions allowable under ACF, and update fleet electrification plan to match future ACF amendments.
4. City should standardize a charge management platform and EV charger.
5. City fleet should leverage CityBus EV chargers for near-term charging flexibility.
6. Conventionally fueled internal combustion generators are currently the most cost- effective option to provide EV charging resiliency to the City.
7. City should explore detailed feasibility, regulatory requirements, and costs of installing generators at EV charging depots.

RECOMMENDATION
It is recommended by the Board of Public
Utilities, Santa Rosa Water, and the
Transportation and Public Works
Department that the Council, by motion,
review and accept the Fleet Electrification
Master Plan
