Located on Watt Avenue by Davidson Drive (near Elverta Rd), this 7.5 acre park is mixed developed and undeveloped. One acre is improved with turf, irrigation and trees; the remaining 6.5 acres is a treasure of open space and nature area through which the Sierra Creek gently meanders. Sierra Creek is free flowing 9 months of the year, and is part of an ecosystem rich in wetland-type plants such as cattails, and an intriguing aquatic and amphibian community in the creek bed. This natural habitat is considered a wonderful and rare natural resource, and has been left undisturbed by the District.

The District received a grant for partial development of the front part of this park. Funding sources for improving the balance of the park have not been available for park completion. This park site is immediately adjacent to Spinelli Elementary School.
