Action
Requested: Award the contract for the construction of Continental Boulevard &
Union Church Road at Davis Boulevard (FM 1938) Intersection
Improvements and West Continental Boulevard & South Peytonville
Roundabout, to McMahon Contracting, LP in an amount not to
exceed $9,750,000.
Background
Information: The purpose of this project is to improve traffic congestion and
increase drainage capacity at the intersections of Continental
Boulevard & Union Church Road at Davis Boulevard, and West
Continental Boulevard & South Peytonville. The City worked with
Kimley-Horn in 2017 to conduct a Citywide Intersection Analysis with
the goal of improving mobility throughout the community. This
analysis showed these two intersections to have a poor level of
service throughout peak traffic hours.
Continental Boulevard & Union Church Road at Davis Boulevard was
determined to have a Level of Service (LOS) E and West Continental
Boulevard & South Peytonville was determined to have a LOS F
during morning peak hour traffic. LOS ranges from LOS A, free flow,
to LOS F, congested forced flow. The recommended improvements
at Continental Boulevard & Union Church Road at Davis Boulevard
will improve the congestion to a LOS C, and recommended
improvements at West Continental Boulevard & South Peytonville
would improve the congestion to LOS B. These recommendations
were included in the 2017 update to the Mobility Master Plan, and
detailed design began in 2019.

In 2022, staff began working on the necessary coordination with
regulatory agencies such as Texas Department of Transportation
(TXDOT), Tarrant County, Franchise Utilities, and the Federal
Emergency Management Agency (FEMA) to mitigate conflicts and
ensure all regulations are met. Staff began coordination with
Franchise Utilities Winter 2023 and utility relocation projects are
expected to be completed in Summer 2025. Final design was
completed Winter 2025.
Continental Boulevard & Union Church Road at Davis
Boulevard (FM 1938)
Mobility Improvements
The planned construction work at the intersection of Continental
Boulevard & Union Church Road at Davis Boulevard (FM 1938)
proposes improvements in agreement with project MT25 in the
Mobility Master Plan and as provided in the 2017 Citywide
Intersection Analysis. These improvements also include proposed
priority sidewalk segments as identified on the Official Pathways
Map. Mobility improvements at this intersection include:
• Northbound right turn lane from Davis Boulevard to
Continental Boulevard
• Eastbound right and left turn lanes from Union Church Road
to Davis Boulevard
• Additional westbound left turn lane from Continental
Boulevard to David Boulevard
• Extend westbound turn lane from Continental Boulevard to
David Boulevard
• Realignment with the eastbound approach crossing Davis
Boulevard from Union Church Road to Continental Boulevard
• Traffic signal additions and reconfiguration with the goal of
accommodating proposed intersection alignment
• Traffic signal timing improvements
• Pedestrian access improvements
This intersection is located within the City of Southlake and is owned
and operated by TXDOT. This work requires coordination with
TXDOT but will be a direct improvement to the citizens of Southlake.
TXDOT will continue to maintain the improvements as well as
monitor and adjust the signal timing within the FM 1938 corridor as
needed after the improvements at this intersection are complete.
Drainage Improvements
The Stormwater Master Plan identifies critical drainage structure #18
near this intersection and a flood analysis was conducted during the
design phase. This flood analysis determined that the existing
culverts were undersized and recommended upsizing the existing
Item 4D
Page 3 of 6
crossing. The proposed drainage improvements to alleviate localized
flooding include:
• Replacing existing culverts with recommended culvert sizes
at the Union Church crossing
• Wire and rock (Gabion) walls and mattresses
• Rock riprap
• Additional inlets and storm line
Street Closure
With the goal of safe and expedient construction in mind, a street
closure on Union Church from Siena Drive to Davis Boulevard is
required for the proposed improvements to critical drainage structure
#18. The street closure will occur during phase one of construction
and the public should utilize posted detours. Carroll Independent
School District (CISD) and the City of Keller have both been notified
of this closure, and staff will coordinate with them as needed
throughout the project.
During the design phase of this project, this closure was discussed
and approved by the City’s internal Office of Traffic Management
(OTM). This internal committee includes all departments responsible
for safety, management, and communication of traffic control, with
the goal of reviewing and communicating any major traffic concerns.
This committee includes members from City Manager’s Office,
Police and Fire Departments, Office of Communication & Customer
Experience, Public Works, Planning & Development Services, and
Economic Development & Tourism.
West Continental Boulevard & South Peytonville
Mobility Improvements
The planned construction work at the intersection of West
Continental Boulevard & South Peytonville Avenue proposes
improvements in agreement with project MT3 in the Mobility Master
Plan and as provided in the 2017 Citywide Intersection Analysis:
• Complete the recommended intersection improvements at
Continental Blvd and Davis Boulevard
• Construction of roundabout at West Continental Boulevard &
South Peytonville Avenue
• Pedestrian access improvements
• Resurfacing of Continental Boulevard between Davis
Boulevard and South Peytonville Avenue
Drainage Improvements
The Storm Water Master Plan identifies critical drainage structure
#19 near this intersection and a flood analysis was conducted during
the design phase of this project. This flood analysis determined that
Item 4D
Page 4 of 6
the existing crossing was undersized and presented options to staff
of how to modify the crossing. Staff chose the option with the lowest
water surface elevation for the 100-year flood event. The proposed
drainage improvements include:
• Addition of two culverts at the Peytonville crossing
• Upstream wire and rock (Gabion) walls and mattresses
• Upstream rock riprap
• Matching existing crossing outlet with the goal of preserving
existing velocities
• Additional inlets and storm line
Utility Relocations
The proposed improvements at this intersection require relocation of
existing City-owned utilities, including:
• 700 Linear Feet of 12-inch water line
• 170 Linear Feet of 8-inch water line
• 580 Linear Feet of 8-inch Sanitary Sewer line

Communication
City staff began coordinating with the public in Fall 2020, when the
efforts began to obtain necessary right-of-way (ROW) for this project
with adjacent property owners. All ROW acquisition was complete by

Summer 2024. Residents within the area were notified via post card
of the project advertisement Spring 2025. The post card sent to
residents displays a QR Code that when utilized would show a
