CA SB1228

Continues the Trade Corridors Improvement Fund to receive and expend revenues from sources other than the 2006 bond act, governed by new Chapter 4.8 of the Streets and Highways Code.

Authorizes the California Transportation Commission to allocate funds for infrastructure improvements on federally designated Trade Corridors of National and Regional Significance, the Primary Freight Network, and high-volume freight corridors, benefiting land ports of entry, seaports, and airports.

Eligible projects include highway and freight rail improvements, port capacity enhancements, truck corridor improvements, border access improvements, and surface transportation connectors that facilitate goods movement and reduce emissions.

Requires allocation to balance urgent state needs, geographic regions, and various ports while prioritizing projects that improve trade corridor mobility and reduce diesel particulate and pollutant emissions using velocity, throughput, reliability, and congestion reduction metrics.

Mandates that projects funded with Greenhouse Gas Reduction Fund revenues must further California's Global Warming Solutions Act purposes and require supplemental funding from local, federal, or private sources equal to or exceeding the state contribution (except border access improvements).
