STORM WATER MANAGEMENT
FOR THE ROUGE RIVER WATERSHED
A COOPERATIVE STRATEGY TO RESTORE THE RIVER
INTRODUCTION
This document is the third written progress report on the status
of the cooperative storm water management strategy adopted in January
of 1995 by the Rouge Project Steering Committee and others and subsequently
presented to the elected leaders of the Rouge River communities
by Wayne County's Rouge Program Office. The previous progress reports
(September 1995, January 1996) identified the accomplishments in
four of the five areas identified in the original strategy and made
a number of recommended changes based upon the discussions held
with the affected communities and other stakeholders during the
first year of the effort. This report summarizes the accomplishments
in the past year of the effort and outlines the actions scheduled
to continue implementation of the strategy.
The Rouge River Storm Water Advisory Group, formed
in November 1994 under the strategy to guide implementation of the
strategy and composed of state and local agencies with regulatory
or management responsibility, identified the following key elements
of the strategy:
-
Implement integrated, monitoring, mapping and
modeling efforts by the Rouge Project to address storm water
issues;
-
Fund demonstration and pilot projects in cooperation
with local communities and other public agencies with storm
water responsibilities;
-
Analyze current options and propose needed
changes in legal framework for managing storm water based upon
hydrologic boundaries;
-
Establish a system to classify subwatersheds
within the Rouge River that will allow projection of information
developed from pilot and demonstration projects to the entire
watershed; and
-
Prepare a long term plan and implementation
process for storm water management throughout the watershed.
This Progress Report summarizes the products and
results of the first four key elements and outlines actions scheduled
to complete the fifth element.
INTEGRATION EFFORTS
The Rouge Project monitoring programs have been expanded to focus
attention on water quality information required to identify and
remediate pollution coming from sources within the separated sewer
areas of the Rouge River watershed. Sampling data from the Rouge
and information from other studies has been used to develop predictive
models that forecast the flow and water quality impacts associated
with planned changes in land use, combined sewer overflow (CSO)
controls and alternative storm water management measures in three
demonstration subwatersheds. Rouge Project staff also developed
a series of water quality indicators that serve as a means of communicating
information on water quality and projected benefits of alternate
storm water management strategies to watershed decision-makers and
the general public. The indicator system has proved useful in building
consensus for the need for storm water management in the watershed.
The expansion of the Rouge Project geographic information
system (GIS) and integration of that system with local GIS efforts
has been the subject of intensive analyses and review by an advisory
group which included SEMCOG and local communities and agencies.
A GIS needs assessment and recommendations for assuring integration
of local GIS efforts with county and watershed-wide efforts has
been completed. Pilot projects consistent with the recommendations
are currently being identified for funding under the Rouge Project.
DEMONSTRATION AND PILOT PROJECTS
Three representative storm water management demonstration subwatersheds
were selected and representatives of local communities along with
other state and local agencies with storm water management responsibilities
have been working for the past year to complete draft storm water
management plans. Two plans have been completed and are now undergoing
review. The third plan will be completed by the end of the year.
A total of 46 pilot storm water management projects
by 25 different communities and agencies have been funded throughout
the watershed and many have been completed. These pilot projects
focus on the application of a best management practice (BMP) to
a specific storm water management problem. Categories of pilot storm
water management projects currently underway include wetlands creation
and restoration, structural practices such as grassed swales and
detention ponds, pollution prevention programs such as the Rouge
Friendly Business Program and other public education and involvement
efforts, erosion control, streambank stabilization and habitat restoration,
and sewage management such as a program to detect and eliminate
failing septic systems. Results from these projects, available 1997-1998,
will be used to provide documentation on the cost effectiveness
of alternative approaches to manage various sources of nonpoint
and storm water pollution and will provide models for other communities
and agencies to consider as part of their storm water management
plans.
REVIEW OF INSTITUTIONAL AND REGULATORY OPTIONS
AND RECOMMENDED CHANGES
An analysis of options for the regulation and financing of storm
water management under state law has been prepared and distributed
to the communities as part of the Rouge Project. Various institutional
options currently available to allow interjurisdictional cooperation
between local governments and state agencies were evaluated and
recommendations made to develop a new regulatory framework that
would allow communities to use an array of existing institutional
and financial options to cooperatively manage storm water.
The communities formed a Core Advisory Group to
develop a set of guiding principles for the development of a watershed-based,
general storm water permit. The guiding principles were ranked in
priority by the communities and used to develop a draft general
permit for consideration by the Michigan Department of Environmental
Quality (MDEQ). The MDEQ subsequently proposed a statewide general
storm water permit incorporating most of the principles outlined
by the Rouge communities. The MDEQ formally adopted the voluntary
watershed-based, storm water permit in July of 1997. The consensual
development of this permit program by MDEQ and local communities
has been instrumental to developing consensus and encourage participation
by Counties, Cities, and Townships, regulators, and the public in
the watershed approach to wet weather management.
ESTABLISH CLASSIFICATION OF ROUGE SUBWATERSHEDS
A detailed inventory comparing land use and cover, sewer infrastructure,
potential pollution sources, population, and other critical factors
affecting the Rouge River has been compiled for each subwatershed.
From this inventory, a matrix has been developed that allows subwatersheds
to be grouped into classifications to evaluate the relative cost
and effectiveness of various storm water management options that
are being implemented as part of the pilot or demonstration projects.
In addition, a guidebook for various BMPs has been
completed. This BMP guideline outlines the appropriate application
of each best management practice, its estimated unit cost and provide
specific reference material for construction or application details.
IMPLEMENTATION OF STORM WATER MANAGEMENT
Many efforts to date, such as the expanded monitoring and modeling
activities, have demonstrated that storm water management is an
integral part of the Rouge River restoration efforts. The storm
water pilot project program and the development of the three representative
storm water management plans have resulted in many new storm water
management activities being initiated in the Rouge watershed. For
example, a team composed on representatives from the three county
health departments has formed to address pollution from failing
onsite sewage disposal systems found throughout the watershed. An
intensive focus on illicit connection removal in one area has increased
recreational use in the watershed by opening up a stretch of the
river to canoeing. Some communities are reviewing their requirements
for storm water management facilities, including design standards
and performance requirements, based on the work conducted under
this strategy to date.
As a next step, an orientation workshop is scheduled
for October to share information on the advantages of watershed
approach, outline the benefits and requirements of the General Permit,
and to solicit ideas on how best to meet application and permit
requirements and how the Rouge Project can best assist with the
General Permit implementation process. The workshop is expected
to generate recommendations on principles and guidelines for meeting
permit requirements. It is anticipated that specific technical advisory
groups, chaired by community representatives, will be established
to develop specific guidance documents to assist with the implementation
of the General Permit.
By December, the Rouge Project will be offering
subgrants, from new funding available from Rouge Grant 4, to communities
and agencies interested in implementing innovative storm water management
projects. It is anticipated that additional subgrants will be available
by January for communities and agencies who have decided to work
together in applying for coverage under the new General Permit
Project staff will continue to support efforts
underway in the three focused subwatersheds, and perhaps in additional
subwatersheds if the interest exists, to complete models for storm
water management programs that demonstrate institutional and financial
cooperation between public agencies in the management of storm water
within a common hydrologic area.
The Rouge Project will continue to explore mechanisms
that will allow the integration of subwatershed management efforts
into a comprehensive watershed approach for the entire Rouge River.
Through participation on the Wet Weather Federal Advisory Committee
we are providing up-to-date information on what is working in the
Rouge Project and finding new ideas to try out.
