Re: Proposed Royal Lane Extension
I.H. 635 to Bethel School Road
Dear Mr. Dean:
As you requested, we have prepared a comparison roadway pavement
and subgrade standards for various entities in the project vici-
nity. This letter summarizes the results of the comparison.
Attached are two exhibits:
Exhibit A - Vicinity Map
Road Section Locator
Exhibit B - Typical Roadway Sections
As noted, City of Dallas and Coppell (Royal Lane) thoroughfare
standards are very similar using 8" reinforced concrete pavement
with a 6" lime treated subgrade.
It is our opinion that such a section with a properly designed
lime treated subgrade will provide satisfactory service for the
proposed roadway. We propose to obtain the services of a
Geotechnical Engineer to analyze the soil conditions at the site
and prepare the design of the subgrade specifically for the con-
ditions encountered.
We are available at your convenience to discuss this analysis in
further detail. Please do not hesitate to contact us.
Sincerely,
Paul A. Lipscomb, P.E.

RE: Railroad Crossing at Royal Lane in Coppell, Texas
Dear Bob:
As promised in my letter of October 10, 1986, (a copy of which is
attached), I am forwarding detailed construction plans for a
railroad crossing at Royal Lane in Coppell, Texas. Also enclosed
are plans for the stacking lane, switch relocations , and
signalization for this crossing.
As I mentioned in my prior correspondence, we are seeking
expeditious approval for an at-grade crossing at this location. The
City of Coppell is committed to completing the extension at Royal
Lane, which will cross your tracks. The landowner's commitment to
fund the construction of the roadway plus the at-grade crossing is
available only for a brief period of time. Again, time is of the
essence. Your cooperation in this matter would be appreciated.
Our Council has begun to renew a positive rapport with Mr. Ted
Searcy of your company's realty division. I had hoped we could work
together in addressing some of the growing pains we are experiencing.
However, the City of Coppell is prepared to initiate condemnation
pr. oceedings if you are not responsive to our offer. We would prefer
not resorting to this action; however, we stand committed to do so,
l-~-necessary.
I had also hoped to hear from you regarding my October 10 letter.
would appreciate hearing from you by this Friday, October 31, 1986.
Sincerely,
Lou Dugg an
Mayor
