Oso Creek Golf Course Creek Channel repairs
Public Service Staff began creek repairs this week focusing on the out fall area near Casta Del Sol Road behind Atria de Sol. Heavy winter storms had eroded the concrete spillway area creating a large cavity in need of repairs. Crews prepared the area and placed the first 150 tons of an estimated 620 tons of rock boulders. Work will continue through mid-September.
