This new 278-bed patient tower of 425,000 sq. ft. was designed to meet the seismic standards required by California State Senate Bill 1953 (SB1953). The hospital will provide acute care pediatric facilities, diagnostics and ancillary services, as well as a Level I emergency department / trauma center. The majority of the structure will be seven stories, with an emergency heliport located on top of the tower.

The new Patient Family Pavilion is an eight-story building which includes 222 patient beds for pediatric and neonatal intensive care, surgery, pediatric ICU, laboratory, material management and administration services. The building includes one level below grade and seven levels above grade.
