"Menlo's been a great spot in my heart because I played (basketball) at the Burgess gym starting in 1960," Mr. Arrillaga told an assembled audience at the Stanford Park Hotel. "I probably scored more points in that gym than any player in its history because I retired at almost age 60."
Mr. Arrillaga is the major private donor to the city's new Arrillaga Family Gymnasium, which will hold its grand opening Oct. 16, as well as to the planned Menlo Park Gymnastics Center.
A basketball player at Stanford University in the 1950s, Mr. Arrillaga has been an active player and coach in Burgess Gym basketball programs for 30 years.
He is a major donor to Stanford University and was listed by Forbes in March as among the "World's Billionaires 2010."
He and his partner Richard Peery are major landowners and landlords in Silicon Valley.
Mr. Arrillaga headlined the awards list in the Chamber's 38th annual awards banquet.
