1. Village of Mount Pleasant Storm Water Utility Pike River Improvements Project

2. Pike River Improvements Project Project is divided into 9 phases Each Phase is approximately mile inlength, stretching over 5 miles through theVillage of Mt. Pleasant Construction began in 2001 Phases 1-5 are complete Phase 6 is currently being constructed 3. Pike River Improvements Phasing Municipal Boundary Phase Limits Watershed Boundary Major Roadways 4. Pike River: Pre-project Conditions Phase 8 5. Primary Goals Flood Control with Expansion of FloodChannel to Keep Flooding within Corridor. Restoration of Riverine Corridor withBuffer Strips. Restoration of Aquatic Habitat with In-Steam Habitat Structures and ImprovedSubstrate. Recreational Corridor Development withTrails Water Quality/TSS Removal 6. Flood Control Each Phase involves expansion of theflood channel to control floodwaters. Three Phases (Phase 1, 4 & 9) alsoinclude large flood storage areas. Construction of Phases 1-3 resulted incomplete or partial release of floodplainrestriction on over 120 properties. 7. Phase 1 Before & After 8. Flooding on Willow RoadAugust 2007 9. Residential Flooding August 2007 10. Phase 4a Construction Aug. 2007 Flood Storage Area 11. Phase 4a Construction Aug 2007Flood Storage Area - Flooded 12. Habitat Restoration Village works closely with various biologists andDNR staff to restore habitat within the Pike Rivercorridor. Native prairie and wetland plantings are typicalthroughout the corridor with annual monitoringand invasive species control. Reconstructed stream provides more naturalhabitat (meanders, fish habitat structures, etc.). Annual monitoring of stream conditions (UWM)conducted to monitor impact of to-dateconstruction and plan for future Phases. 13. Prairie Restoration 14. Pike River Pathway 15. Recreational Corridor Development Over 4 miles of multi-use, off-road bike trailconstructed to-datethroughout the corridor. Trails are open to thepublic year-round. River corridor provideswealth of additionalpassive and activerecreation opportunities. Unlimited access to theriver. 16. Water Quality/TSS Removal Water quality ponds constructed throughoutthe corridor at points of in-flow of runoff. Newly constructed flood channel banks withgentle (4:1) slopes and upland vegetatedbuffers. New development and re-developmentmust meet NR 151 requirements. 17. Phase 4 Water Quality Ponds 18.
