Improved drainage
The area along I-45 from Patton to Crosstimbers will see a significant reduction in flooding. Many other areas along Little White Oak, White Oak and Buffalo Bayous will no longer experience 500-year flood events due to the NHHIP drainage improvements.
Addressing Flooding
With recent serious flooding events, especially 2017’s Hurricane Harvey, drainage improvements are urgent priorities to Houstonians. This document outlines how the I-45 NHHIP plans to mitigate chronic flooding along this roadway.
Air quality is improving
