Public Works Big Fossil Creek Flood Study - BFC7 DR2004
Project Description
This project consists of performing a flood study on the existing BFC-7 Tributary to Big Fossil Creek. BFC-7 begins just south of
Loop 820 with a TxDOT outfall channel south of the highway, then south into the Meadow Lakes subdivision, including portions of
Meadow Lakes Drive, Lake Side Circle, Pebble Court, and the two lakes between Riviera Drive and Meadow Lakes Drive. The flood
study would update FEMA's model to reflect the current hydrology and hydraulics, and upgrade this area to a Zone AE from its
current Zone A status. The engineering budget for this project includes FEMA review fees for the Letter of Map Revision (LOMR)
that will be required to update the maps.

Project Justification
Of the City's 950 acres of 1% Chance Floodplain (formerly known as 100-Year Floodplain), only 85 acres remain classified as Zone
A. These areas are defined using approximate methodologies. Because detailed hydraulic analyses have not been performed, no
Base Flood Elevations (BFEs) or flood depths are shown. The lack of current detailed information poses a problem for the 47
property owners whose homes/lots are impacted by this Zone A floodplain. Since FEMA updated the maps in Tarrant County in
2009, Staff has met with numerous property owners in the Meadow Lakes area, some of whose homes are now located wholly
within the Floodplain, potentially due missing data in the current model. Updating this model not only improves the accuracy of the
City's Floodplain maps, but will potentially illustrate a lower risk of flooding, thereby reducing the necessity of flood insurance from
more than a dozen properties. Performing this flood study also supports the City's commitment to Floodplain Management and the
National Flood Insurance Program. Points will be awarded for this study under the Community Rating System, allowing NRH to
maintain its high standing in that program.

Funding Source: Drainage Utility Fund (120).
