Z100-00-00-X291 - White Oak Bayou and Greens Bayou Watersheds

Z100-00-00-X291 is a collection of major maintenance projects that will repair various types of channel failures along 34 sites within the White Oak Bayou and Greens Bayou watersheds. Portions of the identified channels are considered to be in serious failure and these repairs are necessary to prevent further impact to the channels.

Projects included as part of Z100-00-00-X291 are NOT classified as flood damage reduction projects; however, the channel may be widened in some locations in order to restore the channel conveyance capacity back to how the channel was originally designed.

Projects that fall under Z100-00-00-X291 include:

The total cost for these channel repairs is expected to be approximately $2.9M and will be funded using grants from the Natural Resources Conservation Service and Federal Emergency Management Agency. 

There will be heavy machinery near project sites and substantial vegetation removal operations may be needed in order to properly prepare the site for construction. For public safety reasons, trail users can expect intermittent closures as the projects progress. Please pay attention to posted signage in the project areas.

Construction has already begun at some of the project sites, but anticipated completion for all sites is Spring 2020 depending on weather.
