<br />Electric Vehicle Transition Plan & Charging Infrastructure Evaluation for County Fleet <br />Price Proposal <br />RFQ 367-OC5463 <br />December 23, 2025 <br /> <br />Use or disclosure of data contained on this sheet is subject to the restrictions on the title page of this proposal 5 <br /> <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 d escriptions 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 con siderations, <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 />Docusign Envelope ID: 2559C90D-4549-45D0-8554-7958990EE7B9
