In 1994, citizens passed Measure K, cutting allowed density on the hill by half and allowing the city to pursue further lowering, and in 1996 voters passed Measure R, a special levy including $3 million to buy land on the hill. In 2008, the remaining open space hill was declared a Priority Conservation Area by Bay Area and state agencies. By 2019, when the bonds matured, the city had bought small parcels totaling six acres. The remaining bond funds in 2019 were being spent for access and other improvements called for in the city's plans for the park, adopted first in 1991 and repeated in a new plan adopted in 2012.
