La Porte, TX Environmental Rules: Erosion Control (2026)

Erosion control in La Porte is regulated through the city's stormwater management ordinances and state TCEQ requirements. All construction activities that disturb the ground surface must implement best management practices to prevent sediment from leaving the site and entering streets, drainage ditches, and storm sewers. Common required measures include silt fencing around the site perimeter, inlet protection on nearby storm drains, construction entrance stabilization with gravel pads, and temporary seeding or mulching of exposed soil. Construction sites disturbing one acre or more of land must obtain a Construction General Permit from TCEQ and develop a Storm Water Pollution Prevention Plan (SWP3) that describes all erosion and sediment controls. The SWP3 must be kept on site and available for inspection. Even residential construction on lots under one acre must use appropriate erosion controls as a condition of the building permit. The city may require a grading permit for earthwork activities that are not part of a building permit project. Soil stockpiles must be stabilized with silt fence or other barriers. Tracking of mud onto public streets must be cleaned up the same day. Construction activities near drainage channels, bayous, or wetlands may face additional setback and protection requirements enforced by Harris County Flood Control District or the U.S. Army Corps of Engineers.
