IRVINE, Calif.—The Irvine Company Oct. 18 donated $4 million in honor of the Irvine Unified School District’s 50th anniversary.

The donation represents a $2 million annual increase in the development company’s 20-year, nearly $50 million support of the district’s arts, music, and science education programs, Irvine Co. officials said.

“Education has always been at the core of our planning principles in Irvine, and today’s contribution deepens our company’s decades-long partnership with IUSD, students and families to support enrichment programs in science, art, and music,” Irvine Company Senior Vice President Jeff Davis said.
