RE:
Park West Commerce Center / Final Plat
(Subject: Floodplain Management Meeting on March 2, 1990)
Dear Mr. Davis:
As per your request, we held a meeting on March 2, 1990, at 10:00
a.m. with you, Pat Acker from Albert Halff Associates, Shohre
Daneshmand from our office and myself in.attendance. You made the
following comments:
As of this date, there has not been any type of floodplain
study report submitted the City of Coppell for subject
development.
Your client may retain Albert Halff Associate to conduct a
hydraulic study on Grapevine Creek.
Your client is requesting that the final platting and plan
review continue, since the hydraulic study will be a ongoing
effort.
You indicated that the conditional letter of map revision
which had been issued back in August of 1987, should still be
in effect. The only changes are the future bridge widening on
Southwestern Blvd., the removal of proposed bridge crossing
formerly known as Gateway Blvd. and the relocation of the
railroad bridge.
In addition, Mr. Acker made the following comments:
The conditional letter of map revision has been issued and is
still in effect (see attached copy).
This project has been grandfathered per the new Floodplain
Ordinance.
The actual channelization had started back in the 1970's and
later Albert Halff got involved to finalize the hydraulic
study and received the letter of belief (the conditional
letter) in 1987.
As part of the said hydraulic study, FEMA expressed concerns
over high velocities, indicating this is an unstable
condition.
The proposed drop structure in the vicinity of 1-635 has not
been built as proposed. FEMA does not recognize the
channelization through this property.
Albert Halff Associate will be looking at some other
alternatives to replace the proposed drop structure, in order
to satisfy what FEMA had requested and to satisfy our local
Floodplain Management Ordinance.
Based on our discussion during this meeting and our further review
of your request, we have the following comments that need to be
addressed.
Due to the changes made on the plat since this project changed
ownership and name, the above referenced conditional letter
of map revision does not appear to be still valid.
Furthermore, this conditional letter was issued by FEMA with
the consideration that proposed drop structures would be
built, which is not the case. Furthermore, Pat Acker did
receive a response from FEMA on what would have to be
submitted to have channel accepted.
Please submit a hydraulic study report on the above referenced
project for City's review and comment, which is obtained by
the City through engineering services of Mr. Ron Morrison with
Kimley-Horn. There will be a direct charge review fee not to
exceed $1000.
Provide a schedule on scope of work indicating when the
anticipated completion date on the floodplain study.
In response to your request for continuing with the final
platting of this property, I would like to state that it has
been and will be our intent to work with you as diligently as
we have. However, it is important that, as noted above, a
hydraulic study be submitted immediately for staff's review
and comment in preparing for the related City Council meeting.
Attached for your use and application is a floodplain
development permit. This is required for all new development
in the City of Coppell. This permit is required before the
approval of the final plat and a FEMA conditional letter is
required to receive a floodplain development permit. Of
course, you must be in compliance with the City of Coppell
Floodplain Management Ordinance before a final plat can be
recommended to be approved, unless other arrangements are made
with the City Council.
The City of Coppell staff is totally receptive to modifications and
changes in development, but we need to be cautious to continue to
assure the integrity of the National Flood Insurance Program
(FEMA's requirements) for the entire City of Coppell and that our
current more conservative floodplain management requirements are
adhered to providing that level of protection also.
We appreciate your continued cooperation in developing this
premiere and complex development.
If you have any questions, please call Shohre Daneshmand or myself
at 462-8495.
