Additional Backup Information:
On October 31, 2013, and again on October 30, 2015, flood waters severely damaged Fallwell Lane and threatened the raw water intake structure at the Sand Hill Energy Center. Austin Water’s South Austin Regional Wastewater Treatment Plant also suffered serious damage. Onion Creek flood waters inundated low areas as they flowed into the Colorado River and bank erosion was severe and extensive restoration and stabilization are required.
After the flooding events, temporary measures were put put in place to manage local traffic on Fallwell Lane, however it was determined that a permanent solution was needed to reconstruct and realign key access roads, retrofit water intake structures, and stabilize berms and channels to guard against flood overflows from Onion Creek.
Based on the Preliminary Engineering Report, a decision was made to separate the project into two phases. Phase A would realign Fallwell Lane, relocate and extend water lines, and protect the Colorado Riverbank from damage to the adjacent Fallwell Lane. The Phase B project, known as the South Austin Regional WWTP/Sand Hill Energy Center Flood Mitigation project will create berms, levees, and floodwalls to protect critical City infrastructure. The purpose of this $5,500,000 Phase B amendment is to authorize the design firm to proceed with Phase B design to advance the project to 100% design.
Delay in approving this amendment could impact the completion of the design phase leaving the area at risk of continued flooding.
