This report is fascinating reading.
I've copied several paragraphs that I found interesting and will copy them here, one or two at a time, with comments. I have not found any complete breakdown of the original budget, but there is some accounting of the overruns and some items about the shortfall that are worth pointing out ...
The first excerpt:
1. The renovation of Harding and Fleming Golf Courses would be funded by borrowing $13,127,627 in State Proposition 12 funding to be reimbursed by greens fees through a new "San Francisco Recreation and Park Golf Fund." The total estimated renovation projects cost was $16,027,610, including a new clubhouse. At that time, the Department estimated that only $26,400 (for championship golf tees) of the total $12,791,110 in estimated construction costs for the Harding and Fleming Golf Courses' renovation projects were attributable to PGA Tour Championship requirements. The Department contended that all other renovation costs would have been incurred anyway. By the time the Harding and Fleming Golf Course renovations were complete, the total cost had increased from $16,027,610 to the $23,611,457 shown in Table 6.1 below. This represents a total increase of $7,583,847 million or 47.3 percent. According to a March 4, 2004 memorandum from the Department to the Budget Analyst, the additional expenditures were required due to "unforeseen project costs" related to (a) mandatory destruction of old wells discovered on the site, (b) demolition of buildings previously intended for re-use, (c) golf course drainage and erosion problems, (d) additional maintenance building and clubhouse facilities, and (e) new utilities.
So that's where the extra money went.
