The TxDOT office where the plans are being developed shall forward a copy of the plan sheets along with all hydrologic and hydraulic analyses, reports, and electronic copies of the models to the local FPA, or FPAs if more than one community is involved. The submitted FPA Notification must be complete enough for the community to apply for a Conditional Letter of Map Revision (CLOMR)/Letter of Map Revision (LOMR) if the local FPA deems it necessary; it is not intended to be the CLOMR/LOMR submittal itself. The purpose of the FPA Notification is to document to the FPA any changes or non-changes to the BFE. FPA Notification is required no later than when the project is submitted for letting but should be accomplished as soon as the hydraulic design is complete.

The transmittal letter to the FPA should state that the attached information is being sent for the FPA's floodplain records. It must not ask for the FPA's concurrence, approval, or consent. The FPA has no authority to approve, disapprove, or change the modeling or design but may offer valuable guidance to the designer.

The designer should be aware that, while the designer's office is coordinating with a community, it does not mean that the office is automatically coordinating with the FPA. The FPA may be in a completely different department such as Health, and not Engineering. This is a source of confusion, and may result in a project having problems if the FPA is not involved until late in the design. The designer should verify that the FPA is involved and recommend to the community engineer that the local FPA be involved early in the design process.
