Z100-00-00-X295

Z100-00-00-X295 is a collection of major maintenance projects that will repair various types of channel failures along 56 sites within the San Jacinto River, Hunting Bayou, Carpenters Bayou, Greens Bayou, and Cedar Bayou watersheds. Portions of the identified channels are considered to be in serious failure and these repairs are necessary to prevent further impact on the channels. 

In order to restore channel conveyance capacity to its original design, excavation may widen some channel sections beyond their current condition.

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, if there are trails in the project area, 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 Summer 2020 depending on the weather.
