STRATEGIC ALIGNMENT
This action supports Key Focus Area: Enhance Infrastructure and Mobility.
INFORMATION/BACKGROUND
After the completion of the new Denton Independent School District (DISD) High School located west of
the street intersection of Bronco Way and North Bonnie Brae Street, City staff conducted preliminary
research on the potential construction of the undeveloped portion of East/West Westgate Drive, the
reconstruction of existing North/South Westgate Drive, and the reconstruction of Windsor Drive to help
alleviate the traffic impact from the completed development.
The Westgate Drive Reconstruction Project is a street construction project to bring the existing streets up
to City of Denton street standards. The project limits of the longest street section are from Windsor Drive
to Bronco Way. The project will also provide for permanent connectivity from Bronco Way to the existing
portion of West Westgate Drive which connects to the I-35 access road. The project will also consist of
improvements from the Windsor Drive/Westgate Drive Street intersection to the I-35 access road. The
project scope will also include water, sanitary sewer, and drainage improvements within the project site.
Pedestrian mobility on North/South Westgate Drive will be addressed by constructing a single eight-foot-
wide sidewalk on the east side of the street along the full length of the roadway.
During the City’s plan review of the 60% Plan Set, it was determined that additional services for engineering
and design would be required in order to remediate comments provided by the City’s Engineering Storm
Drainage Division. Amendment No. 1 is to provide services to complete a Conditional Letter of Map
Revision (CLOMR) and a Letter of Map Revision (LOMR) to the Federal Emergency Management Agency
City Hall
215 E. McKinney Street
Denton, Texas

(FEMA). The CLOMR is prepared and submitted prior to the beginning of the project and the LOMR is
prepared and submitted after the completion of the project.
Request for Qualifications for professional engineering services was solicited using the City’s formal
solicitation process. City Council approved a pre-qualified list of engineering firms on May 18, 2021
(Ordinance 21-894).
