Flower Mound, TX Environmental Rules: Erosion Control (2026)

Erosion control in Flower Mound is regulated under Chapter 54 of the Code of Ordinances and the TPDES Construction General Permit (TXR150000) issued by the Texas Commission on Environmental Quality. All construction sites disturbing one acre or more of land must file a Notice of Intent (NOI) with TCEQ and develop a Stormwater Pollution Prevention Plan (SWPPP) before land disturbance begins. Required best management practices (BMPs) include silt fencing along downslope perimeters, storm drain inlet protection, stabilized construction entrances to prevent sediment tracking onto public roads, temporary seeding or mulching of exposed soil within 14 days of final grading, and sediment basins or traps for drainage areas over 10 acres. The SWPPP must be kept on site and available for inspection. Flower Mound inspectors conduct regular compliance checks during construction. The Cross Timbers Conservation Development District overlay requires enhanced erosion controls including additional vegetative buffers and reduced clearing limits to protect the natural terrain and tree canopy. Upon completion, a Notice of Termination (NOT) must be filed with TCEQ after final stabilization is achieved with 70 percent vegetative cover. Residential lot grading must direct stormwater away from foundations and not increase runoff to neighboring properties.
