The Baldwin Hills are a low mountain range surrounded by and rising above the Los Angeles Basin plain in central Los Angeles County, California. The Pacific Ocean is to the west, the Santa Monica Mountains to the north, Downtown Los Angeles to the northeast, and the Palos Verdes Hills to the south—with all easily viewed from the Baldwin Hills.

Ballona Creek is an 8.5-mile (13.7 km) channelized stream in southwestern Los Angeles County, California, United States, that was once a "year-round river lined with sycamores and willows". The urban watercourse begins in the Mid-City neighborhood of Los Angeles, flows through Culver City and Del Rey, and passes the Ballona Wetlands Ecological Preserve, the sailboat harbor Marina del Rey, and the small beachside community of Playa del Rey before draining into Santa Monica Bay. The Ballona Creek drainage basin carries water from the Santa Monica Mountains on the north, from the Baldwin Hills to the south, and as far as the Harbor Freeway (I-110) to the east.
