    • Madison County, Illinois Stormwater Management Madison County Planning & Development Department Alan Dunstan Madison County Board Chairman
    • Metro-East Stormwater Timeline 1991 1992 1995 1994 1993 1996 Stormwater Management and Coordinator Hired Informal meetings compromised of County Engineers and District Conservationists Madison & St. Clair Counties create Metro-East Stormwater Runoff Committee Monroe County added to shared costs Flood of 93’ accelerates interest Counties formalize financial support via NRCS offices
    • Current Efforts of Metro-East Stormwater Management
      • Under the direction of Madison County, the Stormwater Management:
      • Spearheads stormwater management projects
      • Works in close coordination with IDNR and the Corps of Engineers, applying for and receiving various grants for program progression
      • Conducts stream cleanups and workshops that exemplify and conform to US and IEPA Phase II Stormwater standards
      • Passes comprehensive Erosion Control and Storm Water Management ordinances to regulate new development in the County
    • EPA Phase II Storm Water Rules
      • Involves 29 units of government in Madison County
      • Requires urbanized areas to implement programs and develop best practices to control runoff and establish:
        • Public education – outreach and involvement
        • Illicit discharge and outfall detection and elimination
        • Construction site runoff controls
        • Pollution prevention – good housekeeping programs
    • Why Stormwater Management…..
      • Increased development in both the uplands and bottomland areas with a lack of coordinated stormwater management
      • Age and condition of local levee systems
      • Impact of 93-95 floods
      • 2007 Scenario same as 1993 situation
    • Storm Water Legislation
      • Senate Bill 1910 – Sponsored locally by Sen. Haine, Bowles and Reps. Hoffman, Holbrook, Reitz and initiated locally by the Madison County Storm Water Board and SWIMPAC
      • Passed both the House and Senate and signed by the Governor – provides the same authority as upstate counties to our area
    • Storm Water Legislation
      • Allows for the creation of a Storm Water Management Commission
      • The Commission shall consist of equal members of both County Board and municipal representatives from the county’s watersheds
      • Allows the Commission/County to put a front door referendum on the ballot for a property tax or a 1/10 th sales tax (similar to the MEPRD)
      • Funds would be used for storm water improvements and to match funds for state and federal projects
    • Starting Points
      • The principal initiative for the long term planning for storm water management has been the existing 1965 Corps of Engineers Project called the “ESL and Vicinity Interior Flood Control Project” – this project allows for review planning, engineering and now includes ecological restoration as a project purpose – added by Congressman Costello
    • Project Goals
      • The US Army Corps of Engineers ESL and Vicinity Flood Restoration Project is intended to:
        • Restore the Historic Floodplain
        • Restore the bio-diversity of flood plain plant and animal communities
        • Minimize upland erosion and manage sedimentation in the floodplain watershed
        • Reduce flood damage in the bottoms
    • Project Details
      • In general, the recommended plan consists of several project areas involving over 55,000 acres of land
        • Restore bottomland forest habitat 1705 acres
        • Restore prairie habitats 1111 acres
        • Restore marsh and scrub habitat 843 acres
        • Restore lake habitats 460 acres
        • Restore floodplain streams 10.4 miles
        • Construct 131 tributary stream and detention basins
        • Construct embankments, control devices. Culverts, flap gates and new channels in 178 miles of streams
    • Selected Project Areas
      • Dobrey Slough Area
        • Add new forested wetlands and corridors
        • Add new marsh and prairie areas
        • Coordinate with existing plans to widen channels and cleanout stream and ditch areas
    • Selected Project Areas
      • Elm Slough Area
        • Drains much of the bottoms area – including the Gateway Commerce Center
        • Intended to restore capacities to diversion channels
        • Create new wetland – marsh areas
        • Install new pump and channel management systems
        • Coordinate with drainage concerns in Horseshoe Lake
    • Selected Project Areas
      • Spring Lake Action Area
        • Provide flood and sediment storage for Canteen Creek
        • Remove and replace levees, construct new reservoirs
        • Add trails and bikeway to wet areas for recreation
    • Selected Project Areas
      • Judy’s Burdick Sediment Basin
        • Provide for the reduction of sediment in the County ditch
        • Reroute Cahokia Canal and create new holding basins
        • Install “riffle” pools in rerouted creek to limit erosion
        • “ Riffle Pool Pilot Project” now underway –Co-op with Glen Carbon-County-IDNR-Corps of Engineers
    • Next Steps
      • The ESL and Vicinity Restoration Project has been approved by the Corps and has been supported via subsequent E and W appropriations and several WRDA bills. Expected inclusion in next WRDA 07
      • Once fully authorized – appropriations will be required
      • $195,000,000 project – will require local match funds
      • We are requesting “credit” for work already completed to provide match funds – Madison County has already bought properties for this effort in the bottoms area
      • Federal cost = $126,807,000
      • Non-Federal =$68,351,000
      • Requests made to Congressional delegation to support the project
    • Next Steps
      • Chairman Dunstan pledges continued support for the Storm Water management effort
      • Summer 07 Madison County will enter into a partnership with the National Great Rivers Research and Education Center for interns and planning assistance in Planning and Development office
      • Madison County continues to support the efforts of the Phase II Program and coordinates municipal members efforts
      • Storm Water Office is relocating to the Madison County Administration bldg for closer consultation and system resources
      • Madison County has engaged in engineering analysis for Elm Slough and for various Chouteau and Nameoki Township drainage control projects
      • Initiated a Rodent Remediation program to trap Beavers with great success
      • Madison County will continue to apply for C2000 IDNR grants to aid in purchase of Corps designated properties for the restoration project
      • Madison County will continue the partnership with St. Clair, Monroe and other counties in storm water management efforts
      • Need to appoint members of the Storm Water Commission to provide overall policy direction and formulation of the storm water management plan(s)

      • The Commission…
        • 6 County Board members from upland and bottomland communities by watershed and population densities
        • 6 Municipally appointed members from upland and bottomland communities by watershed and population densities
    • Metro Storm Water Commission
      • Form the Commission membership
      • Develop the Commission’s operational rules – bylaws and membership, sub-committees
      • Take steps to develop a comprehensive storm water management plan to identify needs and problems – coordinate with Corps and IDNR
      • Seek funding sources locally and from the state and federal governments
    • The Commission…Moving Forward
      • Develop a commitment for storm water management from communities, business and other interests
      • Use the watershed approach to manage storm water
      • Develop a comprehensive Storm Water Management plan
      • Facilitate with the Corps on the ESL and Vicinity Restoration project
