Drainage study prepared by a Texas PE required for grading permits. Irving includes the Las Colinas urban center with an extensive canal network — construction near the canals requires additional erosion and sediment control. DFW International Airport straddles the Irving/Grapevine/Euless border; projects near airport-controlled drainage must coordinate with DFW Airport Operations.
Local Inspection Requirements
- Requirements
- City of Irving Development Services inspects grading permits at rough grading and final stabilization. Las Colinas canal system requires heightened protection during construction phases.
- Inspector Qualification
- No city-specific certification required beyond TCEQ SWPPP requirements
Special Overlay Zones
Las Colinas Canal Network
Trigger: Construction activity adjacent to or draining into the Las Colinas urban canal system (Lake Carolyn and associated waterways)
Restriction: Erosion and sediment control BMPs must prevent turbid discharge into the canal system; canal is a heavily used amenity; coordinate with Las Colinas Association for projects adjacent to canals
West Fork Trinity River Floodplain
Trigger: Development within FEMA-mapped 100-year floodplain along the West Fork Trinity River
Restriction: Floodplain development permit required from City of Irving Floodplain Administrator; USACE coordination required for work in or near the Trinity River channel
DFW Airport Drainage Zone
Trigger: Construction on or adjacent to Dallas/Fort Worth International Airport property boundaries
Restriction: Coordinate with DFW Airport Operations for drainage connections; airport has its own TPDES MS4 permit and independent drainage infrastructure; runoff quality concerns for deicing fluid management

Jurisdiction Notes
Irving is a built-out inner-ring suburb of Dallas with significant corporate office, industrial, and logistics activity centered around the Las Colinas urban center and DFW Airport corridor. The city is experiencing redevelopment of older commercial and industrial properties. The Las Colinas canal system requires special attention during construction. Irving is a Phase I MS4 permittee (larger urban area) with correspondingly more robust stormwater program requirements. The Trinity River floodplain bisects the city and has extensive FEMA mapping.
Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
