Dahlberg presided over the Tustin Union High School District from 1963 to 1968, when it stretched from Tustin to San Juan Capistrano. It was a period of tremendous growth in the county, and Dahlberg oversaw the construction of several elementary schools, University High School in Irvine and Mission Viejo High School and was among the planners of UC Irvine and Saddleback College.

It was his school building expertise that helped win him the right to build the Dana Point Marina, the first of the two marinas now in Dana Point Harbor. Dahlberg opened the 1,250-slip marina in 1972 and owned the Dana Point Marina Co. at the time of his death.

"Bob contributed a lot to the harbor and helped make it a success," said R.F. Wingard, the county's director of regulations and former director of the county's division of Harbors, Beaches and Parks.

Dahlberg was a native of Tomboy Mines, Colo., a gold mining area near Telluride. His father, who was a gold miner, emigrated from Sweden.

Dahlberg, a graduate of Woodrow Wilson High School in Long Beach and the University of Redlands, was a football coach at South Pasadena High School and Santa Paula High School where his teams won three CIF football championships.

After moving to Tustin, Dahlberg served in a dual capacity as principal of Tustin Union High School and district superintendent for one year before assuming the role of full-time superintendent.

He is survived by his wife, Ann, of Mission Viejo, and four children.
