The City of Austin is seeking to reduce the risk of Riverine Flooding and Storms to the health and safety of the 557,807 residents in the project service area. Of that total population, 287,579, or 51.56% meet the criteria for Low- and Moderate-Income benefit.
This project would protect two of Austin’s critical infrastructure facilities from future flood damage through roadway improvements and streambank stabilization activities. Fallwell Lane is the primary access route to the existing South Austin Regional (SAR) Wastewater Treatment Plant (WWTP) as well as the Austin Energy Sand Hill Energy Center (SHEC) electric generating and distributing facilities. Together, they represent over $700 million dollars of infrastructure investment. Based on their experience in previous flood events, the facilities are at risk of losing access, flood damage, and bank erosion that could cause catastrophic interruptions of service. These interruptions, including loss of electric power would likely result in uncontrolled raw sewage discharge from the WWTP, sewer collection system backups, loss of climate control in residents’ homes and under a worst-case scenario, sewage flooding into residents’ homes.
