12 <br /> Electric Vehicle Transition Plan&Charging Infrastructure Evaluation for County Fleet RFQ 367-005463 <br /> Price Proposal December 23,2025 <br /> • Estimated GHG emissions reductions from EV replacements <br /> • Recommended charger types (e.g., Level 2, DCFC) <br /> When determining the recommended vehicle replacement schedule, we typically start with simple cost- <br /> effective replacements while also staying mindful of the complexity and difficulty associated with replacing <br /> certain use cases due to insufficient alternatives, operational challenges, unreliable technology, safety, <br /> excessive costs, or other identified reasons. For vehicles without currently available EV replacements, the <br /> ICF team will provide insights on the potential future availability as well as detailed descriptions of why no <br /> recommendation is provided in this project. Additionally, for vehicles where an EV replacement is not <br /> recommended due to either excessive cost or lack of technology availability, the ICF team will provide <br /> recommendations for other alternative vehicles and fuels as a replacement phase. This recommendation <br /> will take into account the availability of alternative vehicles and fuels in the Hillsborough area, considering <br /> the operational needs and siting of that vehicle. <br /> Suitability and Operations: In working with the County to find ZEV options which can replace all of the <br /> vehicles in the fleet, ICF employs a collaborative suitability assessment process to identify appropriate <br /> vehicle models which can meet the existing County operations. Using the proprietary EV Model Library in <br /> PowerGuide Analytics, ICF first filters by vehicle options which meet the existing vehicle specifications <br /> collected from the County. This is typically a trivial process for light-duty vehicles but incorporates many <br /> criteria for medium and heavy-duty vehicles such as: <br /> • Vehicle body type <br /> • Daily mileage <br /> • Maximum operating range <br /> • Auxiliary power loads <br /> • Towing/hauling capacity <br /> • Use case <br /> ICF will evaluate manufacturer warranties and support for long-term service when recommending vehicle <br /> options. Additionally, ICF will suggest plans for on-site vehicle repair, maintenance, and replacement, <br /> detailing required resources (e.g., tools and equipment) and staffing (e.g., training and certificates) for the <br /> Operations Center Fleet Maintenance Facility. We will identify and recommend the necessary modifications <br /> of current procedures to meet the needs of EVs. This evaluation will cover a range of considerations, <br /> including updates to equipment, adjustments to the layout, enhancements to safety measures, and other <br /> relevant factors, ensuring that the facilities are fully prepared to accommodate the unique requirements of <br /> EVs. Based on barriers and priorities identified through conversation with County staff, ICF will offer further <br /> recommendations to the County, including best practices for risk mitigation during EV adoption. <br /> Use or disclosure of data contained on this sheet is subject to the restrictions on the title page of this proposal 5 <br />
