RE: Consideration of approval of an ordinance revising the City of Coppell
Thoroughfare Plan to designate Sandy Lake Road as a four-lane divided
boulevard (C4D) from Denton Tap to MacArthur Blvd. and authorizing the
Mayor to sign.
Date: January 10, 1995
The City of Coppell has recently evaluated the roadway system in conjunction with the technical
report for the Roadway Impact Fee Study. As part of the study, I requested the consultant to
evaluate Sandy Lake Road to determine if the section through the heart of Coppell should be a
four or six lane roadway in the future. Council may recall that this road is currently on our
Thoroughfare Plan as a C4D/6. This indicates that it is a four-lane divided boulevard in six-
lanes of right-of-way. During the public meetings for Sandy Lake, there was substantial
discussion as to whether or not this would ever be a six-lane roadway. Because of that
discussion, I had the consultant evaluate the roadway from two perspectives: 1) Sandy Lake as
a four-lane from MacArthur to the west City Limits and six lanes from MacArthur to the east
City Limits; 2) Sandy Lake as a six-lane from the east City Limits to the west City Limits. Both
analysis were performed for the year 2010. In an analysis of this nature, you try to evaluate the
other roadway systems that will be in place for the year in which you are studying. In this case,
the following improvements were included: the S.H. 121 bypass; the improved section of
Beltline Road; and the 161 connector from Trinity Mills to I.H. 635. These roadways all have
the effect of taking traffic off of the heart of Coppell and moving it to the major highways
surrounding Coppell. I also asked the consultant to evaluate Parkway Blvd. as a two-lane
undivided collector as opposed to the current four-lane divided. Council may be aware that
because of the parking on Parkway Blvd. the road basically functions as a two-lane.
Considering all these adjustments to the roadway system, the analysis clearly shows that Sandy
Lake Road between Denton Tap and MacArthur Blvd. should be a four-lane divided roadway
in the future. However, depending on the final interchange design for S.H. 121, that there may
need to be a six-lane roadway between S.H. 121 and Freeport.
Because the City is currently only reviewing the section of Sandy Lake Road between Denton
Tap and MacArthur my recommendation is to revise the Thoroughfare Plan to designate Sandy
Lake Road as a C4D from MacArthur to Denton Tap Roadway. I further recommend that prior
to entering into any type of design contract on Sandy Lake Road from Denton Tap west to S.H.
121 that the City reevaluate the roadway configuration at that time to further calibrate traffic
volumes and determine the proper street designation.
Staff will be available to answer any questions at the Council meeting.

Dear Ken:
The attached figures show the TranPlan number generated under both scenarios. I apologize for not
having the plots ready - TranPlan has not kept up with the new type of plotters. I will furnish you with
plots and a summary.
General observation shows that when Sandy Lake is a 6-lane divided throughout the city traffic
increases along Sandy Lake, decreases along all parallel facilities. Denton Tap Road increased only
between Sandy Lake and S.H. 121 and showed a decrease to the south of Sandy Lake. It is assumed
that the more capacity provided along Sandy Lake attracts residential traffic accessing the freeways.
You will note that freeways themselves decreased when Sandy Lake was only a 6 LD.
Both runs have volumes that do not justify Sandy Lake as a 64ane divided throughout the city.
Sincerely,
Barbra L. Leftwich
