Purchasing Language: Original contract was awarded through a qualifications-based selection process. Prior Council Action: August 3, 2017 – Council approved a professional services agreement with Halff Associates, Inc. for the Fallwell Lane Capital Renewal Project for a total contract amount of $3,000,000. Council Committee, Boards and Commission Action: November 9, 2022 - To be reviewed by the Water & Wastewater Commission. 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 Electrical 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. 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 are 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 damaging the adjacent Fallwell Lane caused by Onion Creek overflows. Phase B will  Item 12 # 22-3409 Water &Wastewater Commission: November 9, 2022 Council: December 1, 2022 provide berms, levees, and floodwalls to protect critical City infrastructure against Onion Creek overflows. Phase A of the project is at 90% design phase, but Phase B of the project is not yet funded. There are available grant programs that could provide up to 90% of the design cost for Phase B. The purpose of this amendment is to authorize the design firm to proceed with Phase B design, which will provide a “shovel ready” project that will benefit from additional grant programs. Halff Associates, Inc. is located in Austin, Texas.
