COUNTY OF COLUSA, CA 4.1 Request For Transportation Commission and Transit Agency Updated: 11/13/2025 11:20 AM B Page 1 MEETING DATE: November 18, 2025 DEPARTMENT: Transportation Commission FROM: Scott Lanphier SUBJECT: Public Hearing and Adoption of Final 2025 Colusa County Regional Transportation Plan Public Hearing and Adoption of the Final 2025 Colusa County Regional Transportation Plan Detailed Description/Background of request The Colusa County Transportation Commission (CCTC), as the designated Regional Transportation Planning Agency (RTPA) for Colusa County, is responsible for maintaining and updating the County’s Regional Transportation Plan (RTP). The RTP serves as the long-range planning and policy document guiding the development, management, and investment in Colusa County’s multimodal transportation system over a 20-year horizon. It establishes regional goals and objectives, identifies existing and future transportation needs, and prioritizes projects that improve mobility, safety, sustainability, and connectivity for all users. The 2025 Colusa County RTP was developed in coordination with the member agencies-the County of Colusa, the City of Colusa, and the City of Williams-and reflects the region’s collective transportation priorities. Green DOT Transportation Solutions was selected as the consultant to prepare the RTP. The planning process was carried out in accordance with the 2024 Caltrans Regional Transportation Plan Guidelines, ensuring consistency with statewide policies, including the California Transportation Plan, Climate Action Plan for Transportation Infrastructure (CAPTI), and Caltrans System Investment Strategy (CSIS). Green DOT’s work included a comprehensive review of existing transportation conditions and needs, demographic and economic trends, and safety and system performance data. Extensive public and stakeholder engagement was conducted through community workshops, surveys, and outreach to local and tribal governments, consistent with the Caltrans RTP guidelines. The Draft 2025 RTP was distributed for a 30-day public review and comment period, and all comments received were reviewed and incorporated into the Final RTP as appropriate. At today’s meeting, the Colusa County Transportation Commission is conducting a Public Hearing to receive any additional comments or concerns from the public or interested agencies regarding the Final 2025 Colusa County Regional Transportation 4.1 Packet Pg. 8

Action Item (ID # 10906) Meeting of November 18, 2025 Updated: 11/13/2025 11:20 AM B Page 2 Plan. Following the public hearing, the Commission may take action to adopt the Final RTP. The Final RTP includes the required Policy Element, Action Element, and Financial Element, identifying both constrained and unconstrained projects based on realistic funding assumptions and anticipated transportation revenues. The RTP also includes an environmental document prepared in compliance with the California Environmental Quality Act (CEQA). With the incorporation of all public and agency feedback, the Final 2025 Colusa County Regional Transportation Plan is now ready for adoption by the Colusa County Transportation Commission. Adoption of the RTP will allow the County and its partner agencies to maintain eligibility for state and federal transportation funding and will guide future programming efforts, including the development of the Regional Transportation Improvement Program (RTIP) and other transportation planning documents. Prior Board Action Adoption of 2018 Final RTP Adoption of 2013 Final RTP Adoption of 2008 Final RTP Adoption of 2004 Final RTP Fiscal Impact/Funding Source The adoption of the Final 2025 RTP does not itself result in the expenditure of funds or generation of any revenues. However, adoption of the RTP allows the CCTC to continue to receive federal, state, and potentially regional funds for a variety of transportation projects. Action for the Clerk Please provide the Executive Director with a Certified Minute Order of the Adoption of the Final RTP.

Colusa County 2025 Regional Transportation Plan – Final Draft 10 0 EXECUTIVE SUMMARY 0.1. INTRODUCTION The Colusa County Transportation Commission (CCTC) is the Regional Transportation Planning Agency (RTPA) for Colusa County. The CCTC’s overall mission is to provide transportation planning for the region. To do so, the CCTC plans, communicates, and coordinates with the residents, stakeholders, and partners of Colusa County, City of Colusa, City of Williams, the California Department of Transportation (Caltrans), and other State and federal entities to create a balanced regional transportation system. Each RTPA is required by federal law (Title CFR 450.300, Subpart B) and State law (CA Government Code Section 65080) to conduct long-range planning to establish their region’s vision and goals and to clearly identify the region’s unique transportation needs. Creation of the Regional Transportation Plan (RTP) is a principal responsibility of the CCTC. The RTP is a long-range planning document that acts as the basis for transportation planning in the region over a 20-year planning horizon. The RTP is required to be updated every four to five years so that Colusa County maintains its eligibility for many of the State’s funding programs. Each RTP update calibrates the region’s needs based on changing demographics, and political, economic, and environmental conditions. The RTP focuses on all modes of transportation including vehicular, bicycle, pedestrian, transit, freight, aviation, and rail. The RTP is developed through a cooperative process between CCTC, Caltrans, Tribal governments, stakeholders, and community members. The primary guidance for RTP development comes from the California Transportation Commission (CTC). The CTC adopted the most recent RTP Guidelines on January 26, 2024, which established the elements and development process required for the RTP. Three elements are required by statute and encompass the framework of the Plan: • The Policy Element (Section 3) identifies legislative, planning, financial, and institutional issues and requirements, as well as providing the regional vision supported by a series of goals that are upheld by specific objectives and policies. • The Action Element (Section 4) describes the programs and actions necessary to support the County’s vision for the identified transportation needs projected for Colusa County over the next 20 years, by each mode. • The Financial Element (Section 5) identifies the current and anticipated available revenue sources to fund transportation projects and programs identified in the Action Element. 4.1.a Packet Pg. 19 Attachment: 2025 Colusa County RTP Final Draft (10906 : Public Hearing and Adoption of Final 2025

Colusa County 2025 Regional Transportation Plan – Final Draft 11 0.2. OVERVIEW OF REGIONAL VISION The overarching regional vision for the CCTC is to maintain a safe, efficient, and convenient countywide transportation system, including roadways, non-motorized systems, transit, freight, air travel, and any other applicable modes that enhance the lifestyle of the residents and meet the travel needs of people and goods moving through and within Colusa County. Historically, the primary local and regional issues are centered around a lack of funding earmarked to maintain the integrity of existing facilities. Legislative efforts including California’s Senate Bill 1 (SB 1) (2017) and the Federal Infrastructure Investment and Jobs Act (IIJA) (2021) have brought some increased funding to the region for maintenance and development of the regional transportation network. Through a state gasoline tax and increased vehicle registration fees, SB 1 is a $52 billion transportation fund that is used exclusively for transportation purposes, including maintenance, repair and rehabilitation of roads and bridges, new bicycle and pedestrian facilities, public transportation, and planning grants. California was allocated $20.4 billion through the IIJA, of which $15.57 billion will be utilized for transportation. Although State and federal funding has increased slightly in the last decade, a significant gap between funding needs and current allocations still persist. The RTP aims to identify needed transportation maintenance and improvements while balancing limited revenues available to fund projects. The following goals have been identified for the RTP: • Goal 1 – Provide and maintain a safe, efficient, and convenient roadway system • Goal 2 – Support regional travel by making it safe, easy, and inviting • Goal 3 – Upgrade and improve roadways in order to preserve the existing regional roadway system • Goal 4 – Provide a safe, convenient and efficient multi-modal transportation system that is part of a balanced overall transportation system • Go
