Background and Discussion:
Taylor Gully Channel is located in the north-eastern part of Harris County, Texas. The project limits of the proposed Taylor Gully Channel Improvements stretch from the Montgomery County boundary on the west to approximately 700 feet upstream of the confluence with White Oak Creek (G103-80-03.1) for a total length of approximately 12,630 linear feet. The entire project is within the City of Houston limits.
Additionally, there is an adjacent Flood Control and City of Houston owned property (Woodridge site G503-06-00) in Montgomery County that is designated for stormwater detention to mitigate for impacts from channel improvements.
The project consists of approximately 12,630 linear feet channel conveyance improvements of Taylor Gully Channel, construction of a detention basin to mitigate the channel improvements and design of a new simple span vehicular bridge over the channel.
Expected Impact:
The overall benefit of this would be a substantial reduction in WSE along Taylor Gully Channel. There would be a maximum reduction in WSE of 6.9 feet and an average reduction of 4 to 5 feet for the 100-year storm event. Also, this project will remove a 100-year flood plain from approximately 276 structures.
Alternative Options:
The alternative would be to select another firm for this assignment which would result in delay in starting this project.
