Hesperia Big Box Retail Project

Solicitation # 2024110259

The Hesperia Big Box Retail Project involves the development of a commercial site in San Bernardino County, California, specifically east of the intersection of Amargosa Road and Key Pointe Drive. The project scope includes the construction of a 167,664-square-foot wholesale retail center with 683 parking spaces, a 14-pump fuel station with 28 fueling positions, a 2,623-square-foot automated carwash facility, and a 205-square-foot office building, along with off-site right-of-way improvements. The project is scheduled for opening in 2026 and requires discretionary actions including a Conditional Use Permit and a Lot Merger. Environmental compliance is a critical component of the project, as it involves the permanent removal of 24.21 acres of Western burrowing owl habitat and impacts to western Joshua trees. Consequently, the California Department of Fish and Wildlife has issued Incidental Take Permits to authorize these impacts. The project has undergone extensive environmental review under the California Environmental Quality Act, identifying significant but mitigable impacts regarding biological, cultural, geological, and noise resources, while noting that transportation impacts related to vehicle miles traveled are significant and unavoidable. Technical requirements include adherence to the Mojave River Watershed Water Quality Management Plan, OSHA excavation safety standards, and specific ADA parking and access requirements. Construction quality is governed by strict soil compaction standards and the requirement for geotechnical approval of all import materials.
