Grand Prairie, TX
Dallas County
Dallas County is inland — no Gulf coast, no Texas Open Beaches Act jurisdiction, and no GLO coastal-construction rules apply. The relevant inland program is the Dallas County Floodplain Development Permit, required for any work in a FEMA Special Flood Hazard Area in unincorporated areas. Most unincorporated land is in the Trinity River floodplain; floodway encroachment is prohibited absent a FEMA CLOMR.

Grand Prairie FAQ
Does Dallas County have coastal development rules?
No. Dallas County is inland — no Gulf coast, no Open Beaches Act jurisdiction, and no Texas General Land Office coastal-construction rules. The inland equivalent is FEMA-administered floodplain regulation. Any work in a Special Flood Hazard Area in unincorporated Dallas County requires a Floodplain Development Permit from the Department of Unincorporated Area Services (214-653-6565).
Do I need a permit to grade or build near the Trinity River in unincorporated Dallas County?
Almost certainly yes. Dallas County DUAS reports that most unincorporated land lies in the Trinity River floodplain, so a Floodplain Development Permit (or a verification letter that the site is outside the SFHA) is required before any grading, fill, fence, or structure. Floodway encroachment is prohibited unless FEMA issues a CLOMR. Inside city limits, the city's floodplain administrator handles permits.
Irving FAQ
Does Irving have any coastal development rules?
No. Irving is a landlocked city in the DFW metroplex, approximately 275 miles from the Gulf Coast. Coastal development regulations do not apply.
