KSA Engineers, Inc. was hired by the City of Sugar Land to complete paving and drainage improvements at the airport.
The development of the East General Aviation Complex required crossing of an oxbow lake that is designated by the Corps of
Engineers as a wetlands. The taxiway crossings using a traditional embankment approach would disturb more than 10 acres of
wetlands and require off-site mitigation of about 70 acres. Additionally, the existing subgrade materials were a mix of fat clays, silts and
sands. The settlement and consolidation associated with the material would produce 1 to 2 feet of settlement of the taxiways.
To resolve both problems, KSA designed two (2) bridge taxiways over the oxbow lake eliminating the issue associated with settlement
and reducing wetlands disturbance to less than 3 acres. The wetlands mitigation project was runner-up in TxDOT’s Environmental
Achievement Awards. Additionally, to meet local drainage requirements, KSA prepared an Airport Drainage Master Plan and designed
a regional detention pond to address all future airport detention requirements.
