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 Austin Energy’s substation, Sand Hill Energy Center. Austin Water’s South Austin Regional Wastewater Treatment Plant in the area east of SH130 also suffered serious damage. Onion Creek flood waters inundated low areas as they flowed into the Colorado River. Bank erosion was severe and extensive restoration and stabilization are required.  Item 13 # 24-4433 Water & Wastewater Commission: April 17, 2024 Council: May 2, 2024 Temporary measures have been put in place to allow local traffic to utilize Fallwell Lane. A permanent solution to reconstruct or realign key access roads, retrofit water intake structures, and stabilize berms and channels to guard against flood overflows from Onion Creek is needed to protect critical City infrastructure from future flood events. Based on the Preliminary Engineering Report, a decision was made to separate the project into two phases. Phase A will realign Fallwell Lane, relocate and extend water lines, and protect the Colorado Riverbank from damage to the adjacent Fallwell Lane caused by Onion Creek overflows. Phase B will provide berms, levees, and floodwalls to protect critical City infrastructure against Onion Creek overflows. The Phase B project is now separated as the South Austin Regional WWTP / Sand Hill Energy Center Flood Mitigation project. This project has been selected for the pending award of a $50,000,000 grant under the Federal Emergency Management Agency. 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. If this RCA is not approved, the City would not be able to begin design on raising and extending the levees around two critical infrastructure plants, significantly increasing the risk of flooding. This amendment is pending review by City’s Change Control Committee. The Change Control Committee was established to comply with Council Resolution No. 20120126-048, which required the establishment of consistent criteria and process to evaluate contractual changes for all contracts administered by the Financial Services Department, Capital Procurement. The Change Control Committee is comprised of management-level subject matter experts.  Disadvantaged Business Enterprise Summary Participation goals stated in the solicitation was 11.72% DBE.
