BACKGROUND:
Glade Road is the only remaining major street reconstruction project approved by the
voters in the 1998 GO Bond Election. The existing roadway is a two lane asphalt rural
roadway section with narrow shoulders and roadside ditches. The Grapevine / Euless
City Limits Line runs down the center of the roadway.
April 8, 2003 (2:47PM)
The new roadway section will be a four lane divided section with landscaped median,
underground storm drainage, relocated water and wastewater systems, sidewalks on
both sides of the roadway, and the possibility of traffic signals at the intersections with
Baze Road and Euless Grapevine Road.
The proposed pavement section will mirror those of Hall Johnson Road and Pool Road.
The engineering services include the preparation of water and wastewater relocation
plans for both the City of Grapevine utilities as well as the City of Euless utilities.
The City of Euless has committed to fund 50% of the construction costs for the project,
all of the construction costs for relocating their utilities, and the acquisition of all of the
right-of-way on their side of the roadway. Likewise, the City of Grapevine will fund 50%
of the construction costs, all of the construction costs for relocating our utilities, the
acquisition of all of the right-of-way on our side of the roadway, the design for the
complete project, construction management and construction inspection. Turner, Collie
& Braden has successfully completed several projects in Grapevine.
The contract incorporates a design schedule of approximately 11 months which matches
the schedule for the last sale of G. O. Bonds in the Spring of 2004 relative to
construction funds for Glade Road.
Staff recommends approval.

systems and proposed internal storm drains to serve the proposed roadway.
Conduct outfall system hydraulic studies to establish starting conditions for hydraulic
design of the proposed internal storm drain system. Also evaluate the potential impact of
the proposed roadway and its drainage systems on downstream drainage and flooding
conditions. Specifically regarding these outfall systems:

■ Conduct a backwater analysis of the channel discharging south into Euless near the
Mulberry Blvd. intersection to establish drainage outfall conditions. Identify any
improvements or mitigation measures necessary to provide adequate drainage of the
Glade Road widening project or mitigate drainage impacts of this project.
• Conduct a hydraulic analysis of the existing storm drain system discharging south into
Euless near the Cambridge Court intersection to establish drainage outfall conditions.
Identify any improvements or mitigation measures necessary to provide adequate
outfall drainage of the Glade Road Widening project or to mitigate drainage impacts of
this project.
• Conduct a backwater and storm drain analysis of the outfall drainage system
discharging northeasterly near the Euless -Grapevine Road intersection to establish
drainage outfall conditions. Identify any improvements or mitigation measures
necessary to provide adequate drainage to the Glade Road Widening Project.
Prepare a technical memorandum summarizing the outfall drainage studies including
recommendations for improvements to be designed and constructed under separate
authorizations.
Determine erosion control requirements for storm sewer or culvert outfalls.
Prepare Drainage Area Map and Hydraulic Data sheets for construction plans.
3.5 Traffic Signal Warrant Study and Signal Plans
Perform warrant studies and prepare a technical memorandum for the intersections at Baze
Road, Euless -Grapevine Road, the southbound SH 360 frontage road, and the northbound
SH 360 frontage road, in accordance with TxDOT standards.
If warrant studies show that signals are warranted, plans and details will be prepared for
permanent traffic signals at the Baze Road and Euless -Grapevine Road intersections. Plans
will include location of all existing and proposed facilities including signal poles,
underground conduit, detectors, pull boxes, controllers, circuit wiring, signal heads, and
electrical sources.
3.6 Landscaping Design
Based on 30% roadway plans, develop a schematic landscape plan, including
recommendations for potential tree preservation or relocation; development of typical
landscape planting schemes for the right of way, medians and intersections; and
development of recommendations for typical hardscape improvements at the two
intersections. Recommendations for portal development or private subdivision walls are
not included.
Based on City comments on the schematic landscape plan, develop construction
documents, specifications, and estimates for median planting, limited right of way planting,
and intersection corner planting. Limited irrigation design will also be included. Prepare

any special specifications required for the work, and prepare construction cost estimates at
each submittal.
4.0 Information To Be Provided By The City
1. Provide City's plat, easement and plan files.
2. Provide available previous studies for the project.
3. Notify residents, establish time and location, and make arrangements for public meetings.
4. Provide right -of -entry and access along the right-of-way and existing easements. Notify
residents in the area of the pending survey work. Provide access to private properties
adjacent to the proposed alignment as required to obtain the required topographic survey,
geotechnical investigations, and environmental assessment.

Dear Roger:
Well, the new fiscal year is under way, and that nieans our Glade Road project si1ouidn't be fay
behind. We look forward to working with the City of Grapevine on this joint project. I am
including my thoughts as to how we will progress, however, we will definitely need to formalize
these suggestions with a City Council approved inter -local agreement.
We have budgeted funds for ROW acquisition during 2003. If the ROW maps are not available,
we will wait, however, we have a window of time available for ROW acquisition during 2003.
We plan to budget for utility relocation in the 2004 budget, and will commit to our half of the
construction cost, not to exceed your estimate of $1,799,000.00. We are still not certain of the
most favorable mechanism for paying our half of the construction costs, but \r ill determine that in
the near future as we begin our inter -local agreement preparation. We appreciate your offers of
assistance and will keep those under consideration as we formalize our agreement.
Roger, it is our hope that construction would begin by spring of 2004, with completion 12-1
months later. Since it sounds as though your schedule may not accomplish that desired time line,
would you respond with your estimated time line for completion?
We took forward to moving forward with this project. Thanks for your assistance on the design
costs and project management. Please call when we need to formalize our agreement.
Sincerely,
Jo . Hennig
