Action
Requested: Approve an Engineering Services Agreement with Kimley Horn to
provide design, construction documents and opinion of probable
construction cost for E. Highland Realignment in an amount not to
exceed $175,000.
Background
Information: The Texas Department of Transportation (TxDOT) is progressing
with the State Highway (SH) 114 ramp reversal and main lane
expansion design in Southlake. This project necessitated
modifications to the Methodist Southlake Medical Center driveways,
sparking discussions with TxDOT regarding the intersection of E.
Highland Street and the eastbound SH 114 frontage road. These
discussions revealed that the current configuration of E. Highland
Street needs to be realigned.
TxDOT has agreed to include the construction of the E. Highland
Street realignment in the larger SH 114 project, contingent upon the
City funding the design package for the realignment. This design
must be finalized in time for inclusion in TxDOT's solicitation for the
SH 114 improvements.
Kimley Horn, the City's engineering consultant, has prepared
conceptual plans and submitted a proposal to perform the required
design services. The scope of work includes:
• Design of approximately 500 linear feet of three -lane
undivided concrete pavement and 100 linear feet of
commercial driveway pavement.
• Improvements to the internal drainage system with outfalls to
Dove Creek, including hydrologic and hydraulic modeling.
• Geotechnical investigations and conveyance instruments for
required right-of-way adjustments.
• Environmental analysis ensuring no significant impacts, as
the realignment will occur on previously developed land.
Approving this agreement fulfills the City's commitment to fund the
design phase of this critical infrastructure improvement.
Financial
Considerations: The proposal outlines a preliminary and final design scope at
$89,700, with additional services for floodplain analysis,
geotechnical investigation, environmental services, and
conveyance instruments, estimated at $85,200. These services
align with TxDOT standards and City requirements, ensuring the
realignment supports current and future traffic needs while
integrating seamlessly with the SH 114 project.
Funding for this agreement is available from the Community
Enhancement Development Corporation as part of the State
Highway 114 Ramp Reversal project.
Strategic Link: The project links to the City's strategy map relative to the focus
areas of Infrastructure & Development and Partnerships &
Volunteerism. It provides this by focusing on Financial Objective
F2: Investing to provide & maintain high quality public assets and
Business Objective B2: Collaborating with select partners to
implement service solutions.
