PATTERSON — The Del Puerto Health Care District has taken another major step toward building a longplanned health care campus in Patterson, selecting global architecture firm HDR to design the 27.5acre project and submitting its master plan to the city for formal review.

The DPHCD Board approved HDR’s hiring in May, calling it a milestone in efforts to expand medical, behavioral health and seniorcare services for residents across the West Side. The campus — one of the district’s largest infrastructure investments — is slated to include an ambulance and administration center, a community mental health clinic, a relocated Del Puerto Health Clinic, and a full range of senior living options. Longterm plans also reserve space for a future hospital.

“This is a huge step forward for our community,” Board President Becky Campo said, noting HDR’s experience designing facilities for rural regions. CEO Karin Freese said the project is aimed at reducing the long travel times many West Side residents face for emergency care, specialty providers and behavioral health services.

HDR will begin design work this summer, with priority facilities targeted for completion in 2028. Full buildout is expected to occur in phases through 2040. Updated renderings shared at a September town hall show a campus designed around green space, walking paths and treelined streets, with buildings arranged to make it easier for patients to move between services. The architecture blends Patterson’s Spanish Colonial style with modern elements.

At its Dec. 8 meeting, the DPHCD Board voted to submit the campus master plan to the City of Patterson, beginning a review process that will include city staff, the Planning Commission and the City Council. District leaders say community feedback will continue to shape the project as it moves forward.
