Re: Corners of Coppell
Dear Ed:
Pursuant to our discussion on Monday of this week relative to the three
questions raised by members of the Planning and Zoning Commission in their
approval of the Final Plat for the Corners of Coppell on Thursday, May
15th, may we offer information to assist you in preparation for the City
Council meeting on May 27th.
First of all, regarding the location of proposed driveway access relative
to existing Kimbel Kourt across Sandy Lake Road, we have verified the dis-
tance from the centerline of the most westerly driveway to the centerline
of Kimbel Kourt to be approximately 140 feet. We feel that this determina-
tion should resolve any concern that the P & Z or Council might have for
the traffic movement across Sandy Lake.
Regarding cost participation in future signalization of the intersection of
Sandy Lake Road and MacArthur Boulevard, we can confirm that such a re-
quirement imposed at this point in time would have substantial negative im-
pact on the project feasibility. Throughout the process of zoning, plat-
ting, site plan review, and engineering plan review, no comment concerning
participation in the cost of signalization had been previously made. No
funds, therefore, have been budgeted for such participation as may be re-
quired by the City at this time. Further, the imposition of such a re-
quirement with the development of this project seems inconsistent with
treatment of earlier developments having impact on traffic in this area and
contributing to warrants for future signalization of the MacArthur/Sandy
Lake Road intersection. We respectfully ask reconsideration of the circum-
stances related to development of the Corners of Coppell.
Since our discussion on Monday, we have more thoroughly considered the
question of driveway width and traffic control. We have discussed this
matter with Wayne Ginn and confirmed his opinion that a 24-foot drive width
would be adequate for two-way traffic, with sidewalks on either side to
gain some distance between the traffic lanes and the bridge railing. We

are of the same opinion that a wider drive than 30 feet would prove to be
detrimental to traffic control.
Finally, we have contracted with an independent traffic engineer to evalu-
ate the proposed access driveways and to offer his findings at the Council
meeting Tuesday evening. We have discussed the question of driveway width
and traffic control with him, but without adequate time to develop basis
for an opinion, he was reluctant to offer comment before next Tuesday.
We appreciate your assistance in resolving these questions and trust that
this information will be of some assistance to you in communicating with
the Council prior to Tuesday evening's meeting.
Very truly yours,
Billy J. Thompson, P.E.
