Board narrows warehouse‑industrial rules, approves a sub‑two‑acre warehouse conversion and defers a truck‑parking rezoning

San Joaquin County supervisors on June 30 approved changes to the county General Plan and Development Title governing the "Warehouse Industrial" land‑use designation, authorized one parcel reclassification to that designation and continued another contested truck‑parking rezoning for further review.

Planning staff said the text amendment refines the Warehouse Industrial designation by requiring pre‑application review for general plan or zone map amendments, strengthening early notification to neighboring cities and agencies, and allowing limited exceptions to the existing two‑acre minimum where a parcel is already developed for commercial or industrial use.

The board approved the text change after city staff from Tracy and other jurisdictions asked for enhanced coordination. Danielle Green, assistant city attorney for Tracy, said the city is not opposed to the specific Harney Lane project but requested earlier notice and partnership — especially because Mountain House and other nearby cities are updating their general plans and spheres of influence.

Following the policy change, the board approved the reclassification and administrative use permit for a 1.01‑acre parcel on Harney Lane (previously used as a nursery office) to allow a traffic‑control business to convert an existing structure and add equipment storage. Planning staff included conditions to address security, site layout and county standards.

Separately, a proposed truck‑parking facility and rezoning for a 14‑acre parcel on North Cherokee Lane drew questions about safe access to State Route 99 and potential expansion of truck counts. The board continued that item to Aug. 4 to allow the district supervisor input and further traffic engineering analysis from Public Works.

Board members emphasized that pre‑application coordination and interjurisdictional notification will be required to reduce surprises for cities and better vet infrastructure and traffic impacts before developers invest heavily in proposals.
