Sunset Park occupies 6.69 acres at 5540 Lake Park Way near Lake Murray in La Mesa, on land that served as the San Diego Chargers' in-season practice facility for roughly four seasons beginning in 1964. Hall of Fame wide receiver Lance Alworth ran routes on the same grass now used by Lake Murray Little League, whose David Madrid Field was dedicated in 2001 within the park's baseball complex—a youth-sports hub that connects to the broader family programming at FIT4MOM La Mesa + Lake Murray nearby. The park accommodates up to 400 guests and includes a full-court basketball court, a children's playground with slides and swings, restrooms, picnic tables, and open turf fields for softball and soccer. The Lake Park Way access road technically passes through San Diego city limits before reaching the La Mesa park boundary, placing Sunset Park at the geographic seam between the two jurisdictions. Post-game families from the ball fields walk to Lake Murray Boulevard dining and coffee options including Come Back Coffee Co. in the Lake Murray corridor. Field scheduling coordinates concurrent Little League, adult softball, and recreational soccer leagues across overlapping seasons, requiring turf-rotation management, portable mound placement, and outfield-line restriping between baseball and soccer configurations.
