San Joaquin County Measure K: What It Is, How It Works, and What It Means for Lodi

Measure K is San Joaquin County's dedicated half-cent (0.5%) transportation sales tax, first approved by voters in November 1990 and renewed for a 30-year extension through March 2041 when nearly 78% of county voters approved the renewal in November 2006. Every taxable retail purchase made in Lodi contributes a half-penny per dollar to this fund, which is distributed to local street repair, highway improvements, public transit (including GrapeLine), bicycle and pedestrian infrastructure, and railroad crossing safety. Over the 30-year renewal period, Measure K is projected to generate approximately $2.64 billion in transportation investment for San Joaquin County.

For Lodi specifically, Measure K is the single most important non-federal source of transportation funding. It directly pays for GrapeLine bus service, annual street repaving, the SR 99/Turner Road interchange reconstruction, active transportation trails, and a pipeline of planned highway, arterial, and bike/pedestrian projects. This report explains the program's origins, funding mechanics, expenditure categories, administration, oversight, and Lodi-specific project history and pipeline.
