Mr. Boesch, who also served as city manager in Menlo Park for seven years, resigned from San Mateo County in November after three years due to what he called "different philosophies" with the Board of Supervisors.
As the local county manager, he earned $270,233 annually plus a $13,338 transportation allowance on top of other benefits. His severance package included three-and-a-half months' salary plus health insurance through April 2012.
The $1.16 million home loan Mr. Boesch received from Menlo Park in 2002 was transferred to San Mateo County. According to a county spokesman, the loan was repaid in full upon the sale of the house on March 22.
