City of Santee Recreation Services administers fourteen community parks, sports fields, and multi-use trails from Building 6 at 10601 Magnolia Avenue. The department co-operates the Santee Aquatics Center alongside Cameron Family YMCA on Riverwalk Drive, providing a 25-meter-by-25-yard competition pool and a separate activity pool with water slide to the general public without requiring gym membership. Programming spans youth league athletics, senior day trips, adaptive recreation, and seasonal community events including the Santee Street Fair on Mission Gorge Road. Youth baseball, softball, soccer, and lacrosse scheduling routes through the 15-acre Sportsplex USA Santee complex at Town Center Community Park on Riverwalk Drive, which the department coordinates for league play and tournament hosting. The aquatics infrastructure centers on a dual-basin configuration where the 25-meter-by-25-yard lap pool maintains eight lanes alongside an adjacent activity basin with integrated play structure, water slide, and dedicated water-exercise zone.
