Tract Map 31689 – Floodplain Analysis & CLOMR

City of Indio, CA

JBA utilized the FLO-2D floodplain analysis software application to prepare the
FEMA Conditional Letter of Map Revision (CLOMR) for the Tract 31689
residential subdivision in the City of Indio, CA. The floodplain analysis was
performed for both existing and proposed conditions, and was used to aid in the
design of two flood control channels to the north and south of the proposed development.

The U.S. Army Corps of Engineers HEC-6 and HEC-RAS software and JBA’s in-house hydraulics software were also used in the channel design. The CLOMR was approved in November 2007.
