Grading, erosion control practices, sediment control practices, and waterway crossings shall be adequate to prevent transportation of sediment and other pollutants from the site.
B. 
For sites that disturb less than one (1) acre unless otherwise exempted under Section 407.030, the owner/developer/contractor must provide a sketch plot plan indicating the overall layout of buildings and other impervious areas, indicate flow direction with arrows and show the location of construction site best management practices. This plan does not necessarily need to be prepared by a registered professional engineer.

For sites that disturb greater than one (1) acre, the owner/developer shall provide a Stormwater Pollution Prevention Plan (SWPPP) and associated drawings prepared by a registered professional engineer. The design and construction guidance in KC-APWA 5100 shall be followed insofar as it is applicable. Additional guidance for construction site runoff control can be found in MDNR's "Protecting Water Quality Field Guide". Stormwater Pollution Prevention Plans must meet MDNR's requirements set forth in the General Operating Permit for Construction or Land Disturbance Activity.
D. 
All construction shall meet the criteria set forth below insofar as they are applicable as determined by the Director.
