RE: Retaining Wall on Don Jones' Property/NLWD East
(Tickler 10/16/90)
Don Jones' Retaining Wall:
After receiving comments and evaluations from Walter Skipwith of
Albert H. Halff & Associates, Steve and I met with Bruce Stockard,
City Attorney, and Dale Jackson, Building Official, on October 10,
1990.
Basically, per Halff's evaluation, the subject timber retaining
wall can not be considered as part of drainage improvement on
Stream G6. This retaining wall appears to be constructed within
the City's 40 feet drainage easement. According to Walter, the use
of timber retaining walls should be avoided in areas subject to
inundation because of their history of failure. We provided the
available information to Bruce Stockard, City Attorney, and he will
review and comment as related to the Don Jones' litigation with the
City of Coppell.
Northlake Woodlands East/Weed Complaint and Drainage/Stream G6:
- Walter Skipwith of A.H. Halff & Associates and I met with Mrs.
Morek and Mrs. Shafer along with a few of their neighbors, on
Thursday, October 11, 1990 at Mrs. Morek's residency on 642
Meadowview. The following residents attended the meeting:

Generally, they indicated that their back yards are wet throughout
the year regardless of rainy seasons, and that it is difficult to
mow the grass in the channel area. The following specific comments
were made:
- Mrs. Morek indicated that when she bought her house several
years ago, nobody was allowed to do anything in the open area
behind said houses, namely Stream G6. But there has been some
types of encroachments in the recent years, referring to houses
along Hawk Lane and Court, etc.
- Mrs. Morek indicated that the existing channel swell in her back
yard has been altered because of different activities upstream
and downstream of this reach, and also some of existing trees
are dying.
- Mr. David Greer indicated that some areas, west and east of
Moore Road, are draining to their back yards and City shouldn't
have allowed this. He is suggesting that this natural earthen
channel be concrete lined or pilot channel and the path of
drainage be well identified and fixed by the City of Coppell;
then affected home owners will maintain such %mprovement.
- Other residents basically expressed their concerns indicating
that this area needs more attention since lots of trees and
grass are dying, and standing water, marsh-like conditions and
high water flooding are getting worst year after year. Their
property lines are somewhat being altered. They also indicated
that throughout the year their back yards are wet and cannot be
maintained properly; and that they are getting warning citations
from Fire Department and on the other hand, they are told by the
City not to disturb the earthen channel.
- Walter and I indicated to the affected residents that we will
look at every alternative, and added that a concrete channel may
not be the best solution, and that no matter what improvement
takes place, maintenance is extremely important to keep the
system functioning properly.
It is important to note that there may be no guaranteed solutions
if high water table is migrating thru this area. The evaluation of
the problem is as important as the solution, and Walter Skipwith
will be investigating this problem in the field and will be
reviewing all possible alternative solutions. The result of his
findings will be included in the final report.
Please let us know if you have any questions.
