This project involved paving 6 islands between
several taxiways covering approximately 16 acres for the purposes of taxiing,
parking or shoulder protection. RBI was responsible for the drainage design
for these islands.
system improvements to FAA and City of Houston Standards. Performed Hydraulic
Analysis for storm sewer capacity analysis and pipe system analysis.
Performed Hydrologic analysis utilizing HEC-1 and HEC-2 models for 10, 50 and
100-year flow rates. Due to environmental considerations, slotted drains with
aircraft rated manholes and inlet structures with fuel traps, were designed to
capture first flush flow (accumulated jet fuel and other petroleum products)
during periods of rainfall.
A 685-ft. 2-compartment 8.5'
x 5' box culvert was designed to connect the existing 3- 8.5' x 5' and 8' x 4'
boxes. This box culvert is the major conduit for drainage from the north
apron, terminal and apron ramp. Use of this aircraft rated box will
facilitate extension of taxiways in the future. More than 6,000 linear feet
of 36", 24" and 18" storm sewer was designed for jack & bore under existing
taxiways and open cut construction methods. Also designed were 2,000 linear
feet of slotted drains.
