Consider executing Supplemental Contract No. 1 with AECOM Technical Services for the
Dam 101 - 30% Design Project.
This Engineering Services Contract with AECOM Technical Services, Inc. to continue
design and analysis work for Dam 101 resulting in 30% design plans. The preliminary
design phase includes the remaining geotechnical investigation, additional environmental
investigations, preliminary easement delineations, and 30% plans and construction
estimates.
This contract has finished major milestones; however, a date extension is necessary to
continue design progress until the final design contract is negotiated. This Supplemental

Dam 101 is a joint project between the Upper Brushy Creek Water Control Improvement
District (UBCWCID) and the City to substantially lessen the frequency and depth of
flooding along Lake Creek, particularly in the Greater Round Rock West area. The
UBCWCID and City signed an ILA that assigned responsibility for coordinating design,
construction, and funding of Dam 101 to the City. The UBCWCID is contributing $6 Million
to the project and will operate and maintain the dam when complete. Per the ILA, the City
already received the initial payment of $2 Million.
