City of Houston Councilmember Dave Martin recently made Kingwood and Lake Houston-area residents aware the that FEMA has authorized the United States Army Corps of Engineers to remove sand and siltation from the Lake Houston mouth bar.
In October 2018, the Corps began removing debris from the San Jacinto River that was deposited during Hurricane Harvey. This project was designated as a FEMA Mission Assignment (DR 4332) and directed the Corps to restore the river to pre-Harvey conditions. DR 4332 has removed debris from three out of four identified sections of the San Jacinto River and this project is due to be completed in this month. The mouth bar, which was identified as the fourth section, was not included in the scope of work for DR 4332.
Last month, the application for an additional dredge material disposal site, as well as one for mouth bar removal, were submitted by the City of Houston for review by the Corps and FEMA. The State of Texas and the City of Houston, as well as multiple stakeholders from the Lake Houston area, requested expedited consideration for FEMA to authorize a mission assignment for the debris removal and dredging of the mouth bar while the equipment is still in the river.
At a meeting two weeks ago in Austin, FEMA issued a directive of mission assignment to the Corps for dredging of the mouth bar at the confluence of the San Jacinto River and Lake Houston. FEMA has been working with Texas Department of Emergency Management, the City of Houston and the Corps to determine the amount of silt deposited at the confluence of the San Jacinto River and Lake Houston attributable to Hurricane Harvey. The calculation is expected to be finalized next week and dredging is expected to begin within 30 days.
