News From Harlingen, Texas
U.S. International Boundary & Water Commission Clearing Areas under Harlingen Bridges
10/02/2019

Harlingen, Texas–The United States International Boundary & Water Commission has begun to remove sediment at three Harlingen locations this week.  The USIBWC received a permit under the US Army Corp of Engineers that allows for removing 25 cubic yards of sediment at three bridge locations along the Arroyo Colorado in Harlingen.

 

The three locations are downstream of the bridge crossings at Business 77, Ed Carey Drive, and FM 509.

 

The work includes mowing the floodplain area to minimize the areas being disturbed to no more than a five foot area along the riverbank.

 

City Manager Dan Serna says the City has been working with the USIBWC for several years to remove the sediment and vegetated growth.  “We’re very grateful that the IBWC is moving forward with this dredging.  This will clear areas within the Arroyo Colorado that will ultimately increase the flow of water and help with flooding.”

 

USIBWC employees will use a long reach excavator to remove the sediment and place it along the flood plain to dry.  Once it dries it will be transported off-site for disposal.  Flood plain areas disturbed less than one acre will be restored to the original contour and allowed to revegetate.

 

No road closures or detours are expected.

 

City Manager Serna says this is only the first step and much work still needs to be done.  “We look forward to continuing to make improvements to the Arroyo Colorado with the help of the USIBWC.”
