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.
