Austin's Barton Springs and Zilker Park air quality benefits from the Barton Creek greenbelt's extensive woodland and the Zilker Park's 351 acres providing exceptional natural filtration along the Colorado River. Vehicle traffic on Barton Springs Road and the surrounding South Austin residential character contribute modest local sources, while the greenbelt's natural ventilation corridor and the Texas Hill Country winds generally maintain good to moderate conditions throughout most of the year.
