What is the purpose of a site map/narrative in a SWPPP?

• A. Describe BMPs, sequence of construction, stabilization, inspections, and maintenance procedures.
• B. Show only site boundaries.
• C. List permits.
• D. Document rainfall.

Answer: (A)

The site map and narrative in a SWPPP exist to lay out how erosion and sediment controls will be implemented throughout the project. It shows where the best management practices (BMPs) will be placed, the order of construction activities, when stabilization should occur, and how inspections and maintenance will be carried out. This integrated plan helps everyone on site—from contractors to inspectors—understand exactly what controls are in place, where they are located, and how they will be managed to prevent sediment and pollutants from leaving the site and to meet permit requirements. Other options only address limited aspects (boundaries, permits, rainfall) and don’t communicate the full set of controls and ongoing procedures that the SWPPP requires.
