Tom,
Interesting question and interesting story. The Olympic Club, which was an amateur athletic club at the time with no golf facility, decided in 1918 to lease and operate the financially troubled Lakeside Golf Club in the southwestern corner of the City. This course designed by Scottish architect Wilfrid Reid, had just opened in 1917.
Seth Raynor was brought in immediately to provide a re-design of this difficult course but for some reason his plan was never implemented.
Due to the growing popularity of golf, the club decided to build two new courses and a 9- hole “Northcliffe” course. Construction of the courses began in 1921 with the entire layout being designed by Willie Watson, another famous Scottish architect of the day. Construction was done by Olympic’s Golf Course Superintendant, Sam Whiting.
Heavy rains caused severe mudslides west of Skyline Blvd in 1925-1926 destroying a large portion of the Ocean Links. Sam Whiting then laid out plans for re-routing both courses and additional land was leased from the City of San Francisco to complete the project in 1927.
In 1955, Robert Trent Jones completed some remodeling of the Lake course pior to the US Open. This included lengthening the course by some 300 yards and the addition of the lone fairway bunker on hole #6.
The Ocean Course had several “in-house” re-routings during the 1950’s and 1960’s and following winter storms of 1983 and severe storms from El Nino in 1996, the Ocean was essentially completely redesigned by Tom Weiskopf and opened in 2000.
The 9 hole Cliffs Course, designed by Weiskopf and Moorish, was rebuilt and opened in 1995.
