The U.S. Army Corps of Engineers, Galveston District, began surveying levels of sediment deposits last weekend within the West Fork of the San Jacinto River in response to a State of Texas and FEMA request.
To determine the level of shoaling and silt accumulation within the West Fork of the San Jacinto River, a New Orleans District Corps survey crew and vessel collected GPS and sonar data near Humble and Atascocita from April 6-9 along a five-mile area between Hwy 69/59 and West Lake Houston Parkway
“Corps Surveyors operated a 20 foot Xpress Boat with survey grade GPS and a sonar transducer to determine sediment deposition,” said Alicia Rea, an emergency management response official with the Galveston District.
“County and City officials conducted a site visit to the locations on April 10, 2018. We believe this is the most prudent action to take to better define the scope of work. The USACE and FEMA are working diligently to expedite the process.”
FEMA responded to a request from the State of Texas and under Stafford Disaster Relief and Emergency Act of 1988, FEMA directed the Corps to begin the initial assessment of the conditions.
Corps Hydrologists will utilize the survey data and use hydrologic modeling to determine the best course of action.
