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. The use of the watershed approach therefore
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 was identified as a major component in
the restoration of the Rouge River. At the heart of the storm water
management approach being used in the Rouge Watershed is the watershed
based Michigan's Watershed Based Storm Water Permit.
This voluntary permit established the process for developing watershed
management plans to address the control of storm water and other
sources of pollution. The Rouge Project has developed extensive
guidance material for Applying
for a Watershed Based Storm Water Permit.
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.
