District 10 Stockton

District 10 is a geographically diverse district lying in the northern San Joaquin Valley and encompassing eight counties; three urban counties on the valley floor and five rural counties located in the foothill and mountain region of the Central Sierra. The counties include Alpine, Amador, Calaveras, Mariposa, Merced, San Joaquin, Stanislaus, and Tuolumne. There are 3,547 lane miles in District 10, which includes four Sierra passes, three rest areas, 29 cities, the Port of Stockton and numerous transit authorities.

Maintenance operations are divided into five geographic areas with 24 maintenance stations all under one-maintenance region. The District has an annual payroll of $38.9 million for approximately 524 permanent and 100 temporary help employees. The annual operating expense is an additional $35.7 million, for a total annual budget of over $74.6 million. The Capital Program consists of approximately 160 active projects ultimately worth approximately $4.5 billion. The Capital Program includes State Transportation Improvement Program & Local projects worth approximately $3.9 billion and State Highway Operation and Protection Program projects that are worth approximately $593 million.

The major urban areas in the district are the cities of Stockton, Modesto and Merced, with a combined population of approximately 1.5 million. The district borders the East Bay Area and continues to experience increased levels of congestion due to heavy commuter traffic through the Altamont Pass and other routes connecting to the East Bay.

The five mountain counties continue to experience growth. This development is primarily focused next to existing foothill communities. Two of the district’s mountain counties border on Yosemite National Park. The district has been very active in interregional issues concerning access to the Park and the development of the Yosemite Area Regional Transportation System (YARTS).
