Coppell Greens-CS120906Mr. LaBerge,
I did not see erosion from the north property to justify me calling the
City of Lewisville for resolution on this situation. You are more than
welcome to contact the City of Lewisville or the property owner to
discuss this issue further.
Thank You, George

Subject: RE: Coppell Greens Erosion to the north
Mr. Marshall,
A large portion of the rain water hitting the property north of us
feeds into the v-ditch (or swale) and then into our spillway and
detention pond. That, and water from our nearby storm drains, are the
only source of water for the pond. The pond has now been dredged twice.
As I understand it, the City paid for it the first time. We paid for it
a couple of years ago now and it wasn't cheap ( approx $30K). Even
though the property north of us is mostly vegetated, one would have to
assume that the silt it filling our pond is coming down stream from
their property. If you looked closely you might have noticed the old
silt fence that is there which is no longer of any value.
Once they develop their property, however, I would anticipate this
problem will go away if they cover most of area and install a storm
drainage system.
It would be appreciated if they put in some silt fences along their
swale and at least attempted to mitigate the problem. In addition,
Coppell Greens could also put in some silt fence in the locations where
we planted the decorative grasses.
I have attached the aerial. I also noticed that they are no longer
aerating their pond with a fountain like they used to, which may be
contributing to our mosquito problem.
Please let me know if you take any action.
Thanks,
Phil LaBerge

Mr. LaBerge,
I took a look at the area to the north of Coppell Greens where you
mentioned there was some erosion issues. I took a few photos of the
area and did not see the erosion you were talking about. In fact, I saw
an area that looked real good in terms of slope stabilization.
In a channelized area such as the segment through Coppell Greens it is
not uncommon to see sediment from underneath the grassed area to deposit
downstream. This is the natural progression of a streambed.
The photos are attached. Please let me know if I was looking in the
wrong area.
Thank You, George
