Updated June 22, 2026 · 209 residents
Onion Creek is a quiet, semi-rural residential community in Southeast Austin known for its spacious properties and scenic, golf-course-adjacent landscape. While the neighborhood offers a peaceful atmosphere with ample green space, residents should expect frequent aircraft noise due to proximity to the airport and a high reliance on personal vehicles for daily errands.
Key Highlights
About Onion Creek
The Onion Creek neighborhood in Southeast Austin was established in the early 1970s as a master-planned residential community centered around the Onion Creek Club. Founded in 1974 by legendary golfer Jimmy Demaret and developer Jimmie Connolly, the club gained national prominence as the birthplace of the Senior PGA Tour, hosting the prestigious Legends of Golf tournament. While the neighborhood is defined by its golf-centric identity and scenic creek-side landscape, it has also been shaped by a history of severe flooding. Following catastrophic events, particularly the 2013 Halloween flood, the City of Austin engaged in extensive property buyouts, leading to the demolition of numerous homes and the creation of the Onion Creek Metropolitan Park. Today, the area remains a blend of established residential development and preserved natural floodplains.
Onion Creek provides a spacious, semi-rural environment characterized by large residential lots and well-maintained landscapes. The area lacks industrial activity, ensuring a strictly residential atmosphere that appeals to those seeking a break from the density of central Austin. Its layout promotes walkability through accessible sidewalks, though the lack of a concentrated commercial core necessitates driving for most daily tasks. Prospective residents should consider the trade-offs of living in this area, particularly regarding acoustic comfort and infrastructure. Frequent aircraft noise is a notable feature of the local environment, and the neighborhood experiences a wide range of age demographics. Families should be aware that local school options, split between Austin and Hays school districts, are currently navigating significant financial and operational transitions. The area is well-suited for dog owners who appreciate the connectivity of local parks and the open, spacious feel of the surrounding landscape.

Onion Creek Rankings
School Districts Serving Onion Creek
Austin ISD is a district in transition, characterized by a sharp divide between its elite, high-performing magnet schools and a significant number of underperforming neighborhood campuses. While academic highlights like LASA and successful bond-funded modernizations demonstrate the district's potential, these are overshadowed by a $60 million budget deficit, declining enrollment, and ongoing state monitoring of its special education department. The district remains a prestigious destination for specific programs, but systemic financial instability and teacher retention challenges in a high-cost environment place it in a mixed category of operational health.

Hays CISD is a district in a state of transition, currently categorized as Mixed/Transition due to a severe financial crisis and inconsistent academic performance across its portfolio.

Sharp disparities exist between its top-tier facilities and struggling campuses like Lehman High School, which has recently faced significant bullying and safety scandals.
