NWA Pre-Construction Stormwater Education
This pre-construction stormwater education program is designed specifically for contractors, developers, and persons responsible for inspecting and maintaining stormwater controls on a construction site to be shared during pre-construction meetings.
All LSD/PP sites are required to have a SWPPP On-Site Contact. This person must obtain a "PARTICIPATED IN TRAINING" card. The link below will take you to the training materials and quiz.
The objectives of the Stormwater Management Program are to improve the quality of stormwater in local receiving waters, to provide and promote education about stormwater issues and concerns, to evaluate design, repair, replace, and improve stormwater facilities and conveyances, and to inspect drainage systems throughout the city. In addition, the Engineering Department and the Stormwater Management Program supports Community Development by providing technical specifications, advice, and expertise to developers and citizens regarding stormwater management and drainage design criteria.
Stormwater and Land Disturbance
The City inspects land disturbing activities that have the potential to release pollutants; particularly onto adjacent properties or into surface waters. Developers must follow Federal, state, and local required stormwater regulations. Best Management Practices must be installed and maintained by qualified personnel. As applicable, the Operator/Owner must follow the Stormwater Pollution Prevention Plan (SWPPP) for sites over one acre in size. Self-inspections must take place according to regulatory requirements.
If planning to disturb more than one acre of land, then a Stormwater Pollution Prevention Plan is required. Please refer to the Arkansas Department of Environmental Quality Website for state permitting procedures. Grading only permits require a complete erosion control plan. Implementing Best Management Practices are required. Self-inspections are to take place once a week or every two weeks and after every .25” precipitation event. Tracking onto city streets is unacceptable. Upon completion of the project, the drainage system must be maintained.
