Re:
Mansions on the Lake
Floodplain Reclamation Study
Mr. Griffin:
I am sending with this letter two copies of the Mansions on the Lake floodplain study for
your review. The study is in two volumes: one is the application package and report for a
Conditional Letter of Map Revision, the other contains the portions of the study oriented
toward the City's design criteria.
The CLOMR application contains the MT-2 forms, HEC2 multiple profile and floodway
runs, and other items required by FEMA. We are requesting a change to the FIRM panel
and a revision to the floodway. Once you have approved the report and are ready to
submit the CLOMR request, I would like to pick it up from you so that I can send it via
overnight service to FEMA. Please let me know if this presents a problem.
The second volume uses the base model from the City-wide Drainage Study and the
Denton Creek ultimate discharges. Attention is given to valley storage, equal
conveyance, and zero increase of stormwater elevations.
I believe this report will confirm that the proposed floodplain reclamation can be
accomplished in accordance with the City's criteria. If you have any questions or need
more information to expedite your review, please do not hesitate to call.
Cordially yours,
Rus rs, P.E.
