RE: Proposal for Traffic Signal Design and Inspection Services
Dear Ms. Daneshmand:
Barton-Aschman Associates, Inc. is pleased to submit this proposal to provide professional
transportation engineering services in connection with the design and inspection of two (2)
traffic signal installations in the City of Coppell. We have prepared a scope of services and
fee estimate based on our recent discussions.
If accepted, this letter will become an agreement between the City of Coppell (City) and
Barton-Aschman Associates, Inc. (BA) to provide the services outlined in the Scope of
Services presented below:
SCOPE OF SERVICES
Our Scope of Services includes the work described in the following tasks and encompasses
the work effort involved in the traffic signal design and inspection of the two (2) intersections
listed below:
MacArthur Blvd. and Samuel Blvd.
Bethel Rd. and Coppell Rd.
Task I - Data Collection
1.1
Obtain base plans (e.g., paving plans) from the City and verify plans in the field.
If existing base plans are not available, the intersection will be drawn based on
field measurements which include roadway widths, lane widths, and curb radii.
This assumes that BA will not have to survey the intersection.
1.2
Contact local utility companies to verify the location of utilities at the
intersection.
1.3
Review 24-hour directional machine traffic counts on each intersection street
from current signal warrant studies conducted by Barton-Aschman.

RESPONSIBILITY OF THE CITY
The City will provide the following to BA:
Existing paving plans for each project intersection.

Review comments.
FEE FOR SERVICES AND METHOD OF PAYMENT
The fee for completing the project will be based on our hourly rates for staff personnel,
current at the time of performance, for staff services rendered. The maximum fee and
expenses for completion of Tasks I through 5 will not exceed 814,572.00 without prior

proposed Scope of Services. Reimbursable expenses are also given.
The fee for extra services, meetings, work sessions, and presentations (and work in addition
to the tasks indicated in the Scope of Services) will be billed separately based on our hourly
rates for staff time and expense.
Direct reimbursement for out-of-pocket expenses such as mileage, reproduction, etc., will be
billed at cost and will be added to the staff time costs incurred on the project.

signal installations at (1) Bethel Road and Coppell Road,
and (2) MacArthur Blvd. and Samuel Blvd. for a total
amount not to exceed $14,572.00.
City Engineer, Kenneth Griffin, made the presentation to the
Council. Following discussion, Councilman Morton moved to approve
the contract with Barton-Aschman, Associates, Inc. to provide
professional engineering services for design and inspection of
traffic signal installations at (1) Bethel Road and Coppell Road,

Tree and Winding Hollow.
Ken Griffin, City Engineer, made a slide presentation and reviewed
the current City of Dallas Road Hump Policy. In response to a
request for a stop sign at the intersection of Burning Tree and
Winding Hollow, engineering studies demonstrate that a stop sign at
that intersection is not currently warranted. Councilman Weaver
requested that the staff look at alternative solutions, other than
speed humps, to control speeding on residential streets.
Councilmen Morton and Thomas suggested we identify a test area and
formulate a policy to provide this type of speed control, including
the possible use of big screen radar. It was the consensus of
Council that a policy should be formulated for presentation at the
August City Council work session. No formal action was required on
this Item.

held May 27, 1992, at 6:00 p.m.

Appreciation Banquet will be held on July 11, 1992.
Do
In reference to a memo from Councilman Weaver to Alan D.
Ratliff, City Manager, regarding the sidewalk issue: the

Elementary School opens, the sidewalk for the park on
MacArthur and on Coppell Road will be included as a
supplement. Staff was also requested to check into the
school district sharing the cost of the installation of
the sidewalk on Coppell Road.
A discussion for the banquet to be held for former
Councilmen Nelson and Cowman determined a favorable time-
frame would be for July. Councilmen Garrison and
Robertson are to work on developing this project.
Mayor Wolfe announced that Alan D. Ratliff, City Manager,
had been voted "Administrator of the Year" by ASPA, and
