Storm Water Management
The early focus of the Rouge Project
was on the control of CSOs in the older urban core portion of the
downstream areas of the Rouge Watershed. As a finite number of point
source CSO discharges could be identified and responsibility for
each defined, the traditional regulatory approach of issuing NPDES
permits mandating corrective action worked relatively well.
Within two years of the first sampling conducted under the Rouge
River National Wet Weather Demonstration Project in 1993, it became
evident that sources of pollution upstream of the combined sewer
overflows were a major contributor to the impaired uses observed
in the river. Storm water runoff and illicit connections to separate
storm water systems were identified as a major source of pollutants
entering the river. Without efforts to address storm water runoff
in upstream areas, the major capital investments to control CSOs
in downstream areas would not result in significant improvements
in the water quality of the river. Later studies emphasized the
need to control storm water runoff that was responsible for the
increasing frequency, volume and velocity of flood flows in the
river. These excessive flows following wet weather events in the
Rouge River watershed were shown to be responsible for significant
impairments to aquatic habitat and riparian properties.
Based upon what was learned, the focus of the Rouge Project became
more holistic to consider the impacts from all sources of pollution
and use impairments in receiving waters by using the watershed management
approach. There is a clear inter-relationship of the pollution sources
within a watershed that demands an inter-related approach to a solution
in order to achieve water quality standards and associated designated
uses within a watershed. A piecemeal approach of focusing only on
sources of pollution or a group of sources will not achieve the
desired results nor will it achieve the acceptance of the residents
of the watershed. The use of the watershed approach therefore has
emerged as the most cost-effective and logical approach to water
resource management in the Rouge Watershed and elsewhere. For a

As discussed in greater detail in the Overview
Description of Storm Water Management in the Rouge Watershed,
the control of storm water emerged as a major component in the restoration
of the Rouge River. An ad hoc Rouge River Storm Water Advisory group
developed a storm water control strategy. After review and endorsement
of that Strategy by local communities and the Rouge River Steering
Committee, the Strategy was implemented.
At the heart of the storm water management approach being used
in the Rouge Watershed is the Michigan General
Storm Water Permit. This voluntary permit establishes the process
for developing watershed management plans to address the control
of storm water and other sources of pollution.
The Rouge Project has provided a unique opportunity for addressing
storm water in order to restore and protect an urban river system
by using a cooperative, locally based approach to pollution control.
