San Joaquin County, California
San Joaquin County joins Stockton, Tracy, Lodi and Manteca at the point where the Central Valley meets the Delta and the Altamont Pass commute to the Bay Area. Distribution centers along Interstates 5 and 205 and affordability-driven housing demand carry the market, constrained by Delta levee and flood-protection standards, the Delta Plan, and prime-farmland conversion rules.
