Flower Mound FAQ
Is my Flower Mound property in a wildfire zone?
Flower Mound does not have formally designated wildfire zones. Properties near Grapevine Lake and within the Cross Timbers Conservation Development District face higher seasonal risk due to native cedar and post oak vegetation. Texas A&M Forest Service provides wildfire risk maps at texasforestservice.tamu.edu.
What happens during a Denton County burn ban?
During a county burn ban, all outdoor burning is prohibited in unincorporated areas of Denton County. Within Flower Mound town limits, outdoor burning is already prohibited year-round under Ch. 38, so the burn ban primarily affects the extraterritorial jurisdiction.
