Title
Consider a resolution authorizing the Mayor to execute an Interlocal Agreement with Williamson County regarding improvements to sewer line along Hairy Man Road.
Body
The Brushy Creek Regional Wastewater System (BCRWWS) was formed in 1988 to convey wastewater from the Brushy Creek basin to the BCRWWS East Wastewater Treatment Plant located on State Highway 79. Wastewater flows originate from the cities of Cedar Park, Leander, Round Rock, and Austin, and from Fern Bluff and Brushy Creek Municipal Utility Districts. The City of Round Rock administers all the contracts associated with the BCRWWS.
Williamson County hired Cobb Fendley, Inc. to perform engineering design for Great Oaks Boulevard at the intersection of Hairy Man Road and Great Oaks Blvd. Their design work includes the widening of Great Oaks Boulevard, and the placement of a bridge that crosses both Brushy Creek and Hairy Man Road. This project includes work associated with the 54-inch portion of the regional wastewater line that was constructed in 1999, because the line is located in County right-of-way and not in a designated wastewater easement.
The new bridge that will be constructed with this project impact an existing regional wastewater line manhole located in the existing intersection. A new manhole will need to be placed outside the confines of the bridge structure to allow access to the wastewater line for future maintenance. Additionally, this project includes 18 minor and five major manhole grade adjustments along the regional wastewater line.
An Interlocal Agreement (ILA) is needed for this project between Williamson County and Round Rock, the authorized agent for the BCRWWS. The City of Round Rock will be reimbursed by the BCRWWS partners based on their capacity ownership in the regional line.
