Summary
Mansfield requires erosion and sediment controls on all construction sites. BMPs include silt fence, inlet protection, and stabilized entrances verified during inspections.
The CGP requires construction site operators to develop and implement a Stormwater Pollution Prevention Plan (SWP3) prior to commencing construction. A SWP3 is a document that outlines construction plans and best management practices (BMPs) to control pollutants that may be discharged in stormwater runoff. Small Business and Local Government Assistance (SBLGA) has developed templates to help you develop your SWP3.

Full Breakdown
Mansfield requires that all construction sites prevent sediment from leaving the property and entering streets, drainage ways, or neighbor lots. Best Management Practices include perimeter silt fences, stabilized construction entrances with crushed rock pads, storm drain inlet protection, and timely stabilization of disturbed areas. Sites disturbing 1 acre or more must file a Notice of Intent for TCEQ general permit TXR150000 and implement a SWPPP. Builders must keep the SWPPP on site and update it with inspections after each rainfall of 0.5 inches or more. Mud and sediment tracked onto public streets must be removed daily. Concrete washout must be contained in a lined pit or dumpster and disposed of off-site. Mansfield inspectors verify BMPs at pre-construction and during ongoing inspections. Penalties for sediment violations can include stop-work orders and TCEQ enforcement actions with escalating fines. Contact Public Works at (817) 276-4200 for guidance before clearing begins.
