RE: Denton Creek/ Coppell Community Park
Don Andrews with the Flood Management Unit of the Texas Water
Commission visited the Vista Ridge channel with me on July 27.
During the visit he suggested the City take the actions listed
below in our i quiries of the workings of the channel as the local
floodplain admi istrator supersedes the Water Commission's authority
where they exis .
A dialogue between the channel's engineers, our City Engineer,
and Consulting Engineer should take place to correct any
discrepancies.
At regular intervals the silt in the man -made channel's
interesections With the natural, channel be removed.
The trees that ave fallen into the natural creek need to be removed
as they will i pede river flow and at high flows cause debris to
form log jams.
The project has not been finalod and an extension of the construction
period granted, according to Mt. Andrews.
Any further co cerns or questions should be directed to the Denton
County Levee Im rovement District #1.

Denton Creek/ Coppell'Community Park
I recommend the City of Coppelll take action to further insure
adequate flows remain in the main Denton Creek channel by
encouraging remedial action take place under the Texas Water
Commission's order of October 28, 1985 by the Denton County Levee
Improvement District, owner of the channel.
I base this reconmendation on personal observations (as indicated
by the enclosed photographs) of flows from Denton Creek flowing
into the channel, reducing the velocity of the creek flow allowing
for growth of aquatic vegetation.
In the original order, a report to be sent the City by the DCLID
would indicate the necessity of taking remedial action to insure
this, correcting observed problems. I will contact the Levee
Improvement District to obtain a copy of the report to the
Commission outli ed. Based on the findings of that report, a
more accurate by othesis could be developed to determine further
action.

RE: Denton Creel /Coppell Community Park
Dear Larry:
P. O. Box 478
Coppell, Texas 75019
214 -462-9010
I have been developing a file concerning the diversion channel
north of the Denton Creek main channel within the Vista Ridge
development. Mike Allen of Unvest had asked staff, through Alan
Ratliff to look into this because the current flows in the main
creek at this t Ime appear to be of less velocity than experienced
in past years an5 of a lower wager level.
I visited this area and took some photographs which show water
flowing into b h channels at' each intersection with the other,
but more promine tly from the creek into the diversion.
The channel was built as a reclamation project under a ruling
by the Texas Water Commission dated October 28, 1985. The
commission in its ruling had stated construction be completed
within two years of the date of ruling and that a study at the
expense of the Denton County, Levee Improvement District #1 be
compiled, deter ining any remedial action necessary due to the
diversion of water. Have you any knowledge or information relating
to this which may be helpful as the two requirements of the order
remain unfulfil ed as of this date, according to James Mirabol
of the Texas Watler Commission staff.
Should you have further information on the creation, Board of
Directors, or operations of the DCLID #1, I would very much like
to review these, too. Some of this may be included in the
Lewisville information obtained) with the agreement.
i
Any other legal facts you can �rovide, or if you wish to establish
a file, any materials we have could assist you in becoming
more aware of the district, fell free to contact me or Steve Goram
at 462 -8495.

RE: Denton Creek /Coppell Community Park
`dF�c
I have received the plans requested from Phil Deaton of Dannebaum
Engineering, project manager folr Vista Ridge. These plans indicate
several intersections of the man made channel with the natural
channel with no provision for diversion of water due to low flow.
The photographs of these intersections taken by me further confirm
this is occuring and the ecology of the main channel is changing
from a fast moving, constant flow to a more passive flow, allowing
for growth of al ae and other aquatic plants.
I made several attempts to contact the Denton County Levee
Improvement Dis rict #1 and did get someone who was delivering
materials, answering the number as, "Vista Ridge pumping station ".
Upon receiving this, I contacted the Texas Water Commission to
speak with someone in their reclamation project division. I reached
a James Mirabol who had some knowledge of the project and discussed
the concerns I had and to obtain further information.
Mr. Mirabol, du ing the discussions, looked over the commissions
order and indica ed several discrepancies occuring:
The first is that the project', was to have been completed within
two years of the issuance of the order dated 28 October 1985.
Mr. Mirabol and Mr. Don Andrews confirmed no final inspection
has taken place or receipt of any documents stating completion
on file at their office.
The report ev ulating the performance (including flows) of
structures during low flows prepared by the Denton County Levee
Improvement District #1 has not been filed. The report was to
analyze the effect, if any, of the diversion of water between
the two channel;, propose any remedial action, if any, necessary
to correct obs rued problems. Mr. Andrews is the hydrologist
for our area and will be makin a visit to our area in late July.
I have given him our number and address for the purpose of visiting
with him to bec me more famil'ar with this issue. He will also
be inspecting the channel at which I asked to be included to show
him those areas of concern discussed over the phone.
No new information, specifications or drawings have been sent
to the Commission since this project started. This would indicate
no changes have been made from the original plans approved by
the Water Commission.
The only action taking place that the Commission staff is aware
of since the Commission ruled pctober 28, 1985 was a request from
the Attorney General's office for a certificate of compliance,
assuring the use of bonds for the program of reclamation proposed.
To date, this i
regarding this
