Flood Control District updates work on Warwana Drainage Improvement Project
The Harris County Flood Control District is continuing to collaborate on a drainage improvement project with city of Houston Public Works to improve the channel from Witte Road (Western boundary) and Shadow Wood Drive (Northern boundary) to Warwana Road (Southern boundary).
This effort to optimize the channel’s level of service will include repairing culverts, clearing blockages, removing vegetation, and planting new trees to help stabilize and protect the channel from future erosion. This effort will also require the removal of some encroachments (fences, decks, sheds, etc.) extending into the right-of-way.
HPW started the cleanup and vegetation removal work for the project in February. Based upon recent community feedback on the initial work, HPW and the Flood Control District agreed to modify the project approach. Following the modified approach, the HPW contractor will turn over the channel improvements portion of the project to the Flood Control District crews for completion.
The Flood Control District will utilize smaller equipment and manual methods to clear and desilt the current channel in a context sensitive manner. The desilting effort will include surveying the topography of the channel, determining if any additional trees need to be removed or pruned to allow access to the area, and the installation of gates to restrict access after the completion of the project. The project is expected to be complete by the summer.
The Flood Control District’s Urban Forester will make every effort to minimize impacts to trees along the channel. HPW will serve as the point of contact for residents in the area to select the new trees that will be planted based on the Flood Control District’s list of tree species desirable for replanting. The Flood Control District’s Urban Forester will also be involved in the location of the new tree plantings to avoid future conflict with the restored channel. The next optimal time for planting trees is this fall.
