Some RestrictionsCoastal Development
Irving is a landlocked city in the Dallas-Fort Worth metroplex with no coastline, so coastal development regulations do not apply. The city has no coastal zone management program, tidal regulations, or beach setback requirements. Development near waterways including the Elm Fork of the Trinity River and various creeks is governed by floodplain regulations.

Heavy RestrictionsGrading & Drainage
Irving requires grading permits for land disturbance activities under the Land Development Code. All development must manage drainage to prevent adverse impacts on adjacent properties. Post-development stormwater runoff must be detained to match or reduce pre-development flow rates.
