The Buffalo Bayou Fluvial Geomorphic Assessment (BBFGA) is a project to investigate the environmental conditions responsible for bank erosion and sedimentation issues along Buffalo Bayou from Shepherd Dr. to Jensen Dr., including intense rainfall events and a variety of other external forces. Several extreme flood events have occurred since the completion of Buffalo Bayou Park in 2015, most notably, Hurricane Harvey in August 2017.
The BBFGA aims to improve the stability and resiliency of Buffalo Bayou’s banks and create a plan for bio-stabilization of key areas that were either damaged and repaired following Hurricane Harvey or are identified in this BBFGA as needing attention. The BBFGA was conducted from November 2019 to December 2020.
The primary objectives include:
- Quantify and map spatial extents (boundaries of the locations) and types of channel stability issues
- Understand the causes of erosion
- Develop conceptual, practical and executable solutions to erosion issues with appropriate regard to stormwater conveyance, site stability and public accessibility
- Develop a prioritized project list and high-level cost estimates to address the erosion and sedimentation issues
The prioritized project list from the BBFGA is awaiting the completion of the U.S. Army Corps of Engineers’ Buffalo Bayou Tributaries and Resilience Study (BBTRS). Draft alternatives within the U.S. Army Corps of Engineers’ study may have a direct impact on the BBFGA prioritized project list.
Multiple sites within Buffalo Bayou Park were recently repaired from storm damage caused by Hurricane Harvey and slopes were stabilized with turfgrass following construction. Additional revegetation of the Hurricane Harvey repairs is currently being implemented using recommendations from the BBFGA.
