Jessica,
I’m preparing a CLOMR for the City based on the effective models from FEMA. The City indicated that you
suggested they use DFIRM data for map revision efforts – which I agree with. The City was also under the
impression that no new modeling was done for MapMod, and that the latest models are from the Master Plan
(Halff) efforts in the 90’s and a subsequent LOMR for Parkway Blvd. Do you have any information as to what
hydraulic model the DFIRM data is based on? Most notably, Parkway Blvd. and Denton Tap Rd. are not in the
FEMA model, and the floodway encroachments don’t match the preliminary maps. Any information you can
provide would be much appreciated. Thanks
