Re: Sandy Lake Project 91-838
(Coppell E. City Limits to Dallas city Limit)
Letter dated October 10, 1995
Memo to Coppell City Manager dated October 5, 1995 &
Conference of October 10, 1995
Dear Mr. Griffin:
The purpose of this letter is threefold, first to respond to the
concerns listed in your letter to Dallas County dated October 10,
1995 concerning the bridge plans, second to provide you comments
relative to the issues presented in a memo to your City Manager
dated October 5, 1995 and third to provide you minutes of the
Agency/Consultant Co-ordination Conference of October 10, 1995.
Letter dated October 10, 1995
County staff members met on October 13, 1995 to evaluate your
comments. In addition, Irv Griffin of my staff met with our
consultant, Charles Gojer and Associates, on the same day to
evaluate the design impacts of your comments. For ease of reference
we will reply to the seven (7) comments indicated in your letter as
follows:
1. We had previously instructed our consultant for the project to
utilize 4:1 slopes instead of the 3:1 slopes that was shown on
the preliminary plans you reviewed.
2. As in Item $1, we had previously instructed the consultant to
utilize 27 feet face to face paving lanes in the City of
Coppell.

3. Concerning your request to modify the pavement transitions at
each end of the bridge, our consultant has been instructed to
begin evaluation of your request. At first glance compliance
with your request seems possible. Remaining issues (relative
to bike lanes) with this request are mentioned in our comments
to your memo to Coppell's City Manager dated October 5, 1995
relating to the handling of bicycle traffic on the bridge.
4. At first glance, we believe your request can be accommodated.
However, our consultant has several questions prior to making
plan changes. Irv Griffin will be contacting you for
clarifications or questions relating to vertical clearance,
width of flat area desired, guard fence, and what type of
traffic, i.e., pedestrians, bicycles, maintenance vehicles,
etc., you anticipate needing such access.
5. At the Carrollton end of the bridge, currently no provisions
for either bike lanes or sidewalks are provided at the east
end of the bridge. By letter to Tim Tumulty dated May 31, 1995
the County requested the City of Carrollton's specific desires
with respect to sidewalk and bike lanes at the east end of the
bridge. By letter to the County dated June 8, 1995 Tim Tumulty
indicated that Carrollton did not desire that either bike
lanes or sidewalk be incorporated into the County's project.
6. You are correct in stating that conversations have occurred
with Mr. Harrington concerning access to his property. We are
aware that Bill E. Jessup, P.E., formerly Project Engineer for
Dallas County on this project, met with the property owner to
discuss and work out access details.
Several of the issues, such as location of retaining wall and
the sidewalk that had initially been shown on the plans,
mentioned in your October 10, 1995 letter had previously been
addressed as you suggested and apparently without your
knowledge. I have, additionally, instructed Dallas County's
Project Engineers to copy you with all future documents
relating to Coppell's portion of this project.
Also, you mentioned the plans showing parking on the right of
way. This will be revised. This is to inform you that no
parking spaces on City Right of Way will be shown on the
County plans without first obtaining specific written
concurrence of the City of Coppell.

Before leaving this topic several other items come to mind.
Have you personally talked to Mr. Harrington about the access
plan? If you have not, do you feel that a meeting, in the near
future with Mr. Harrington would be appropriate? If so, we
will make Dallas County Project Engineers and representatives
from the appropriate consulting engineering firms available
for the meeting. Also, if you like, a representative from
Dallas County's Property Division could participate. You may
call Irv Griffin at 653-6423 if you wish to arrange such a
meeting.
7. This item relates to Item #3; specifically regarding striping.
Again, at first glance, this seems possible. This is to advise
you that we have instructed our consultant to evaluate your
request for likely compliance.
Memo to your City Manager dated October 5, 1995
We appreciate you providing a copy of your memo to Coppell's City
Manager dated October 5, 1995 relating to the handling of bicycle
traffic on the bridge. Although you did not ask for comments, we
are providing the following:
1. You have indicated a desire for bicycle access all the way
east to McInnish Park. This desire is somewhat different than
that of the city of Carrollton. By letter to the County dated
June 8, 1995 Tim Tumulty indicated that Carrollton did not
desire an extension of the bicycle lane beyond the limits of
the proposed bridge structure. Also, we have verbally
discussed this with representatives of the City of Dallas who
also did not desire bicycle lanes at this time.
2. In accordance with Dallas County policy all costs associated
with the extra pavement width must be funded by the City. To
date neither City, i.e., Carrollton or Dallas, has indicated
a willingness to fund this extra cost. In your letter to Jim
Jackson of March 30, 1995, you indicated a commitment to fund
on-street-bike paths. Is the City of Coppell willing to commit
to funding on-street-bike paths in another City such as
Dallas, in order to accommodate access to McInnish Park?

3. The preliminary park improvement plans provided to Dallas
County do not indicate that provisions have been made for
bicycles either by widening the Park Access Road 3 feet or by
a constructing a separate paved facility for a bicycle path.
Conference of October
Please make reference to the minutes of the October 10, 1995
Coordination Conference (copy attached) held at this office. This
is to request that you review the entire minutes carefully and
advise Dallas County, in writing, of any topic that does not meet
with your understanding of the discussions.
You may call Irv Griffin or Alberta Blair-Robinson at this office
if you have questions concerning the above, wish to review copies
of any or all of the letters mentioned in this letter, or have
questions concerning any other feature of the bridge project.
Sincerely,
