Restoration Successes: Healthy Beaches, Healthy Perceptions


Published on

Great Lakes beaches are vital to our economy, ecology and way of life. Keeping beaches healthy is our responsibility. Great Lakes Restoration funding is critical for improving our beaches by providing dollars for public education, monitoring to pinpoint pollution sources, projects to eliminate pollution sources, and monitoring to ensure restoration success.

    2. 2. City of Kenosha <ul><ul><ul><li>Population: 99,218 </li></ul></ul></ul><ul><ul><ul><li>Square Miles: 26.6 </li></ul></ul></ul><ul><ul><ul><li>Watersheds: </li></ul></ul></ul><ul><ul><ul><ul><li>Pike River -> Lake Michigan </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Lake Michigan Direct Tributaries </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Des Plaines River -> Mississippi River </li></ul></ul></ul></ul><ul><ul><ul><li>Located: </li></ul></ul></ul><ul><ul><ul><li>Approx. 32 miles from Milwaukee </li></ul></ul></ul><ul><ul><ul><li>Approx. 52 miles from Chicago </li></ul></ul></ul><ul><ul><ul><li>City Owns approx. 4.5 miles of the 6 miles of Lake Michigan Shoreline within the City of Kenosha. </li></ul></ul></ul>Kenosha, Wisconsin Lake Michigan
    3. 3. Beaches <ul><ul><ul><li>5 Beaches within the City of Kenosha - this will be the first project to enhance water quality at an outfall within the City limits </li></ul></ul></ul>City of Kenosha - Shoreline of Lake Michigan ALFORD PENNOYER SIMMON’S EICHELMAN SOUTHPORT
    4. 4. Major Outfalls <ul><ul><ul><li>There are 9 major outfalls within the City of Kenosha that discharge directly into Lake Michigan. </li></ul></ul></ul>City of Kenosha – Major Outfalls to Lake Michigan
    5. 5. GLRI Grant for Pennoyer Beach Outfall Infiltration Basin Nearshore Health and Nonpoint Source Pollution
    6. 6. Project Purpose <ul><ul><ul><li>Kenosha Stormwater Utility is committed to: </li></ul></ul></ul><ul><ul><ul><li>Protecting the water resources within the City of Kenosha for the use and benefit of the public. </li></ul></ul></ul><ul><ul><ul><li>Providing educational opportunities for the residents, visitors and school age children to identify the issues surrounding the health of our natural resources including the impacts stormwater has on our environment. </li></ul></ul></ul><ul><ul><ul><li>The Pennoyer Outfall provided an opportunity to combine these two goals into an educational opportunity to have a project on the ground that helps identify these issues while providing a method to enhance water quality. </li></ul></ul></ul>
    7. 7. Pennoyer Beach Health <ul><ul><ul><li>Impaired beach by the Wisconsin DNR due to high levels of bacteria encountered during monitoring. Beach often closed due to high levels of bacteria </li></ul></ul></ul><ul><ul><ul><li>- Testing of the outfall resulted in an average reading of 2,500 MPN / 100 mL which is approximately an order of magnitude higher then acceptable levels for bathing/human contact.

    8. 8. Pennoyer Beach Health <ul><ul><ul><li>Heavy storms often create turbulent flows that impact the beach causing sedimentation to be discharge to the Lake. </li></ul></ul></ul><ul><ul><ul><li>- Seagulls concentrate on the beach which may also be the cause of poor water quality. </li></ul></ul></ul>Photos Courtesy of Julie Kinzelman
    9. 9. Characteristics of Pennoyer Outfall <ul><ul><ul><li>Drainage Area – 29 Acres </li></ul></ul></ul><ul><ul><ul><li>98% Residential Land Use </li></ul></ul></ul><ul><ul><ul><li>A 36-inch stormwater outfall discharges to a public beach in Pennoyer Park. </li></ul></ul></ul>Outfall
    10. 10. Project Purpose <ul><ul><ul><li>Design and Construction of: </li></ul></ul></ul><ul><ul><ul><li>Stormwater Treatment and Infiltration Basin at the storm sewer outfall on Pennoyer Beach </li></ul></ul></ul><ul><ul><ul><li>System of Upstream Best Management Practices (BMPs) to aid in the performance of the basin as well as reduce operation and maintenance costs. </li></ul></ul></ul><ul><ul><ul><ul><li>Sub-Surface Sedimentation Vaults </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Parkway Bioswale Installation </li></ul></ul></ul></ul>Taken By: Aerial Photos of America 2004 Discharge from Pennoyer Outfall on Pennoyer Beach <ul><ul><ul><li>Nearshore Health and Nonpoint Source Pollution </li></ul></ul></ul>
    11. 11. Project Details Preliminary Plan designed by the SWU’s Consulting Firm - AECOM
    12. 12. Infiltration Basin <ul><li>Stormwater Treatment Infiltration Basin will: </li></ul><ul><li>Collect, Detain, Store, Filter and Infiltrate Stormwater from the Drainage Area </li></ul><ul><li>Reduce Bacterial Loading onto the Beach </li></ul><ul><li>Reduce nonpoint source pollutants (sediments) by reducing some of the turbulent flows </li></ul><ul><li>will modify the outfall location to allow for more acceptable grade transition from top of the hillside to the beach </li></ul>Preliminary Plan designed - AECOM
    13. 13. Infiltration Basin <ul><li>Stormwater Treatment Infiltration Basin will: </li></ul><ul><li>Be planted with Native Plants and Beach Grasses creating a berm/dune around the outer limits and reduce erosion issues. </li></ul><ul><li>Provide a change to the ecosystem to potentially make this area less attractive to sea gulls who prefer open areas. Julie Kinzelman’s research has found approximately 8,080 gulls during 43 monitoring events which likely play a factor in the health of Pennoyer Beach. </li></ul><ul><li>Will take approximately 2-3 years for plants to mature </li></ul>Photo Courtesy of AECOM Bradford Beach – Milwaukee, WI
    14. 14. Subsurface Sedimentation Vaults <ul><li>Subsurface Sedimentation Vaults will: </li></ul><ul><li>Act as a pretreatment device for the infiltration basin </li></ul><ul><li>Collect Debris and some sediment before discharging into the Treatment/Infiltration Basin </li></ul><ul><ul><li>extend the life of the facility </li></ul></ul><ul><ul><li>reduce the operational and maintenance costs associated with the basin. </li></ul></ul>Photo Courtesy of AECOM (Not Pennoyer Beach)
    15. 15. Parkway Bioswales <ul><li>Parkway Bioswales will: </li></ul><ul><li>Act as a pretreatment device for the infiltration basin </li></ul><ul><li>Provide an Educational Component to the neighborhood, residents, visitors and children </li></ul><ul><li>Allow the residents to take ownership of the project </li></ul><ul><li>Provide a reminder that what we do on our properties and within our communities impacts our Lake </li></ul>Source:
