This property was once an old farm, acquired by the city in order to create an 18-hole golf course to replace the 9-hole West Hills Golf Course which was closed to make room for the zoo's relocation. The course was designed Erv Thoreson, a landscape architect with the Park Bureau. Construction of the course, named Progress Downs by Commissioner Bean, began in 1966 and opened for play in 1968. In 1999, the course was completely redesigned by PP&R Golf Manager John Zoller into a 7,100 yard, championship 18-hole course with a covered, lighted driving range. It was renamed RedTail Golf Course after the red-tailed hawks that nest in the surrounding trees.
