RE: Floodplain Study for Alexander Tract
Thank you Ken,
I will put the 91 flows from the Halff City Wide Master Drainage study to
establish the ultimate 1 DO-year profile. Mike Boyd

Mike
I have signed the forms for the study that needs to be submitted to FEMA.
It can be picked up in the Engineering Department 255 Parkway Blvd. Coppell
anytime between the hours of 8 am to 5 pm.
For the ultimate study, I am looking for the elevation on the 100 year
ultimate flow so I can correctly set finish floors. Without the ultimate
study, I will need to rely on the 1991 Halff Study which would require
finish floors to be in the range of 491 to 496+. This would negate the
advantage of the floodplain study to relocate the floodplain.

Ken, .
I received the attached documents from Nathan D. Maier Consulting
Engineers, Inc. today. After I have had a chance to review the model to
see that it matches the approved LOMR submittal, I will forward a table
of ultimate water surface elevations to you.
Thanks,
