4. BRAZOS RIVER WHERE : YOU ARE HERE Grand Parkway LID 7 Levee River Bank Segment to be Protected

4. BRAZOS RIVER WHY : Prevent future erosion and loss of river bank that could lead to LID 7 Levee Erosion of the Brazos River north bank levee failure and the potential for Minimum distance from downstream of the SH 99 bridge flooding throughout New the bank to the levee is Territory during a future extreme approximately 200 feet. flood event on Brazos River. 2017 Bank Line Erosion of the Brazos River north bank upstream of the SH 99 bridge 2014 Bank Line Maximum observed bank erosion is in excess of 180 feet in the past 3 years, including over 120 feet after Hurricane Harvey.

4. BRAZOS RIVER HOW : Utilize river training structures, engineered scour protection, and armored slopes to divert energy away from the outer bank, reduce scour potential, and prevent continued bank erosion.
