Project 3. Onion Creek Trail Suitability Analysis
Project 3. Onion Creek Trail Suitability Analysis
Students will use these criteria to analyze and select a preferred route for the Onion Creek Greenway trail running through Travis County Southeast Metro Park.
Travis County is developing an Onion Creek Greenway that will stretch 21 miles from the confluence of Onion Creek and the Colorado River to the confluence of Onion and Slaughter Creeks. The trail will provide a Barton Creek Greenbelt-like amenity for eastern Travis County. The first phase of the Greenway Master Plan includes an approximately mile long trail segment that begins near the confluence of Onion Creek and the Colorado River and runs through Travis County Southeast Metro Park. Travis County park planners have identified distance from the creek, slope, and soil properties as the most important criteria to consider when selecting the trail route.
