Dear Mr. Goram:
We have pursued this issue on behalf of the City to the full
extent of our responsibility as project engineer. Attached is a
copy of the contractor's final response to our requests that they
repair the damaged driveway. As you can see, they attribute the
failure to traffic loadings which were not anticipated for a
driveway of this tYpe. Additionally, the damaged area, to the
best of our knowledge, is beyond the ROW on private property and
is not the responsibility of the City.
Please let us know if we can be of further assistance in this
matter.
Sincerely,
John C. Karlsruher,
Project Engineer

Re: Denton Tap Improvements
Dear Mr. Karlsrusher:
Your recent letter to Mr. Mike Lacy, regarding a driveway problem at
Northlake Nursery was referred to me for handling.
We learned at a meeting and on-site inspection with Mr. Fikes that
this driveway in question is used for truck deliveries grossing
80,000 lbs. and tandem truck loads of fill materials, both of which
have a wheel loading greater than that of normal vehicular traffic.
We are not at all surprised ~hat a failure occured under these condi-
tions as it would most certainly do again and again until replaced
with pavement of adequate design. It is not apparent to us that this
failure was, in fact, caused by unsatisfactory workmanship and mater-
ials as your letter states.
It should be noted that this driveway has an abrupt change in grade and
a limited area of entry for large vehicles which necessitates a turn
before the driveway is cleared. This condition should be addressed in
consideration of design changes to handle heavy truck loading.
Our conclusion is that replacement of a similar design driveway would
not have economic support nor would it resolve the problem for the
owner.
We are available to meet with you or your representatives at your
convenience in an effort to work out a satisfactory solution.
Respectfully,
Manager
