Austin City Code Title 25 and the Environmental Criteria Manual Section 1.6 require erosion and sedimentation controls for all land-disturbing activities. In March 2025 the City Council approved strengthened erosion protections along the Colorado River downstream of Longhorn Dam. Developers must submit Erosion and Sedimentation Control Plans and install Best Management Practices (BMPs) before grading begins. Inspections are required during active construction.
