As a component of the Airside Improvements Program at George Bush Houston Intercontinental Airport, Kenall designed drainage improvements associated with the paving of six islands between several taxiways at Terminals B and, covering approximately 16 acres for taxiing, parking and shoulder protection.

Our drainage and storm system improvements were designed to FAA and City of Houston standards. We also performed Hydraulic Analysis for storm sewer capacity and pipe system analysis. We performed simulations with HEC-1 and HEC-2 models for 10, 50 and 100-year flow rates, and designed a 685-feet 2-compartment 8.5′ x 5′ box culvert to connect the existing 3- 8.5 ft. x 5 ft. and 8 ft. x 4 ft. boxes. Our design included more than 6,000 linear feet of 36-inch, 24-inch and 18-inch storm sewers for jack & bore under existing taxiways and open cut construction methods, as well as 2,000 linear feet of slotted drains.
