Indiana Stormwater Quality Manual

Guidelines for Storm Water Quality Measures
In addition to the Hamilton County Stormwater Design Manual the Indiana Storm Quality Manual provides general guidelines and specific storm water quality measures for:
  • Controlling soil erosion
  • Controlling and treating the non-point source pollution associated with the sediment-laden runoff
  • Managing and treating of pollutants associated with post-construction land uses
These guidelines will provide guidance to help minimize the adverse impacts that land disturbance, construction activity, and development can have on soil and water resources. This manual also discusses the philosophy and planning procedures critical to developing an effective storm water pollution prevention plan.

If there are any conflicts with the Hamilton County Stormwater Design Manual contained in the IDEM Manual, the Hamilton County Manual will supersede the Indiana Storm Water Quality Manual.
