Chula Vista stretches across southwestern San Diego County between San Diego Bay and the Otay Mountains, extending from National City south to the international border with Tijuana. The city encompasses distinct areas including the older western neighborhoods near the bayfront, Eastlake and its master-planned communities in the eastern hills, and Otay Ranch developments that continue pushing toward the border. As the second-largest city in San Diego County, Chula Vista's economy centers on cross-border commerce, logistics operations near the port, and a substantial commuter workforce, with significant employment in healthcare, retail, and public sector jobs serving both the local population and the broader binational region.
