The project calls for adding 85,000 square feet of space, a new surgery department and three-story parking garage. The hospital also plans to make all of its semiprivate patient rooms fully private.
Dignity Health officials will present the proposal before the Santa Cruz County Board of Supervisors this week.
If approved, the first phase of the project will break ground next summer. The project will take about 10 years to complete, according to the report.
