BRAZOS RIVER

Brazos 100-Year Overflow

a a a a a WHY:

Improve level of protection from Brazos River Flooding. Brazos River floodwaters can enter New Territory through the US 90A - Grand Parkway Underpass during high stage river events Current operational plan is to place orange tubes to block the floodwaters Evacuation is required once Brazos River flood levels are projected to exceed ground elevations north of US 90A
