Summary:

The Airport, in conjunction with TxDOT Aviation and City of Arlington Public Works, completed a drainage study in FY
2022. The existing storm drain infrastructure has deficiencies in capacity on the south end of the airport. Model results
indicate ponding to the south of the airfield during all storm events, with runoff overtopping Green Oaks Boulevard
during the 25-year and 100-year storm events. Flooding in this region can be attributed to undersized pipes that convey
runoff below the vehicle service roads, as well as the volume of the runoff directed to this outfall location. New,
increased drainage infrastructure is needed to control stormwater and prevent future flooding from continuing to cause
issues.
