Re:
Denton Tap Road Improvements from Sandy Lake Road to Denton
Creek - Glen Hinckley's Driveway Request.
Dear Mr. Doyle:
We have reviewed the attached Handwritten Memorandum dated April
16, 1989 as well as the Subdivision Ordinance and our files for
the project. We have the following comments:
1. gBoth the driveway and the slopes along the front of Mr.
Hinckley's property are addressed in item No. 8 of our
August 25, 1988 letter to Mr. Hinckley, copy attached.
2. ~'Research of our project survey notes along the Hinckley
property failed to produce any evidence of any existing
drives connecting to Denton Tap Road prior to the
beginning of the Denton Tap Road Improvements project.
3. ~ The 30 foot wide driveway shown on Mr. Hinckley's sketch
meets the maximum width requirements for a tract with
Commercial zoning; is within the allowable limits for
Industrial zoning; and exceeds the maximum width for
Residential zoning.
4. 7 The 30 foot wide driveway shown on Mr. Hinckley's sketch
' would be allowable in the location indicated under the
terms of the Subdivision Ordinance if, and only if, the
road referred to as Mills Road were actually a dedicated
road right-of-way. (See attached Figure 2)
Se
As it currently exists Mills Road is not currently
dedicated to the City of Coppell as a road right-of-way
and therefore must be considered as a driveway onto
Denton Tap Road. The location of the driveway shown on
the subject sketch would appear to allow a sufficient
spacing between itself and the "Mills Road" drive to
accommodate a speed limit of ~5~mph as shown in the
table on page 12 of Appendi~'-A of the Subdivision
Ordinance. It is more likely that a speed limit of 45
mph will be established when the project is complete
which will require that the proposed driveway be moved
approximately 52 feet further to the south.

Using the dimensions provided on Mr. Hinckley's sketch
and the current Unit Prices in the Denton Tap Road
Improvements from Sandy Lake Road to Denton Creek
Contract we estimate the cost of the proposed drive to
be as follows:

SUB TOTAL H]#CKLEY ORIVEWAY $1,831.13
7.7 Unless Mr. Hinckley can prove to your satisfaction the
. existence of a driveway from his property to Denton Tap
Road prior to the beginning of construction of the
project, you may wish to require him to bear the cost of
the subject driveway.
In summary: the grading along the front, of Mr. Hinckley's
property can be handled under the current project to eliminate a
steep slope adjacent to the road along the property and to allow
for proper drainage; and the subject driveway will be acceptable
in its proposed location as long as there is a certainty that the
dedication of R.O.W. for and construction of Mills Road will be
accomplished by the adjacent property owners.
F'Both Kevin Peiffer and myself have reviewed this request, as
asked, and you may consider this our joint response.
Sincerely, ~ / ~
