The greenway is built on the grounds of the former Robert Mueller Municipal Airport, which operated as Austin's primary commercial airport from 1930 until 1999.
The park functions as a major low-impact development stormwater system, using natural vegetation and bioswales to clean runoff instead of conventional concrete pipes.
The landscaping exclusively utilizes native Texas plant species to minimize water usage and eliminate the need for synthetic fertilizers or pesticides.
It connects directly to the larger Mueller greenway system, which totals over 140 acres of public parks and open space.
The soil and grading were specifically engineered to slow down floodwaters during heavy Central Texas rainstorms, protecting downstream areas.
The Southwest Greenway is a 32-acre urban park and ecological corridor located within the Mueller master-planned community in Austin, Texas. Designed as a key component of Mueller's sustainable redevelopment on the former Robert Mueller Municipal Airport site, it features native Texas landscaping and restored grassland habitats. The park serves as a vital stormwater management feature, incorporating engineered bioswales and detention ponds that filter urban runoff before it reaches the Colorado River basin. A network of paved multi-use trails winds through the acreage, connecting residential areas directly to commercial hubs and other neighborhood green spaces. Visitors frequently encounter local wildlife, including migratory birds, turtles, and pollinators attracted to the restored prairie flora. Public art installations and educational signage are integrated along the pathways to inform visitors about local watershed ecology and urban conservation. The greenway is a popular recreational destination for running, cycling, and casual walking among local residents.
