Engineering Services Division

The Engineering Department provides oversight, direction, and management of the engineering design program for the entire U.S. Section. The Engineering Department designs and develops plans and specifications for construction and renovation of buildings, hydraulic structures, and wastewater treatment plant infrastructure and conducts hydraulic studies, including developing HEC-RAS and HEC-HMS computer models for IBWC projects such as the Canalization, Rectification and Lower Rio Grande Valley Flood Control Projects.  The Engineering Services Division (ESD) provides license and permit review for projects that may invoke the 1970 Boundary Treaty; and acts as point of contact on these projects with the Mexican Section. ESD is responsible for graphic support services and maintains the official record drawings for IBWC projects.

  1. Rio Grande Levee Integrity Study.  ESD has been an active participant in planning condition surveys for USIBWC levees, pursuant to flood control project upgrades. This work is being performed by the U.S. Army Corps of Engineers, Engineer Research and Development Center in Vicksburg, MS and employs the use of LiDAR.  The initial condition assessment studies were completed in June of 2004. With the results of these assessments and with the new LRGFCP hydraulic model information completed in 2003, the U.S. Section has developed a work plan for levee improvements in the LRGFCP. The US Section, in cooperation with the City of Hidalgo, TX has raised the USIBWC levee along the City’s new Hike and Bike Trail, completed in 2006.  Construction of Phase I of the Hidalgo Levee Rehab Project is tentatively scheduled for FY 08.  Design of Phase 2 of the Hidalgo Levee Project is ongoing.
  2. Hydraulic Studies. ESD has completed hydraulic studies for the Rio Grande at Presidio - Ojinaga, Del Rio-Ciudad Acuna, Laredo-Nuevo Laredo, Eagle Pass-Piedras Negras, and the Lower Rio Grande Valley, and is currently contracting for updating and validating the LRGFCP hydraulic model, scheduled for completion in 2007.  The Corps of Engineers has extended the Upper Rio Grande Water Operations Model from Caballo Dam to American Dam in El Paso using a two dimensional hydraulic model(FLO2D) and current LiDAR data,  completed in 2006,  and is working on a further extension of the model to Fort Quitman, TX, scheduled for completion in 2007.
  3. Rectification Levee Raising Project - FEMA decertification of USIBWC levees in El Paso County, TX, in February 2006 has resulted in public and local government pressure to upgrade the levees to FEMA criteria.  The USIBWC plans on raising approximately 8 miles of USIBWC levees, within a 15 mile reach between International Dam and Riverside Dam in the Rectification Project within El Paso County to meet the minimum 3 feet of freeboard criteria.  This will enable USIBWC to partially certify this reach before the end of calendar year 2007.  ESD has prepared an updated hydraulic model and is working on developing the design drawings for this critical and essential project.
