Watershed Plan BMP Title BMP Description BMP Outcome Huron Chain of Lakes Promote collaboration in watershed management Find partnership opportunities - Schools, Business, Creates a community responsibility and stake in water resource Institutions Recognize need to expand funding for staff, programs, protection and commitments; and act Ensures the communities ability to fund desired improvements Huron Chain of Lakes Seek alternative funding sources Secure funding to establish Huron Chain of Lakes monitoring program Possible grant programs, or storm water fee assessments Monitoring will help to direct water resource conservation efforts Create a funding source for land Directed land/rights acquisition will preserves identified priority Huron Chain of Lakes acquisition Possible transfer or purchase of development rights Fines for violations can fund both illicit discharge and areas Create legal penalties to illicit related water quality programs, fees can be assessed Huron Chain of Lakes discharges for revenue generation based on mitigation costs and/or punitive assessments Provides opportunity to create and direct new revenue stream Structural practices similar to wet ponds that incorporate Treatment, settling and storage of storm water. Aesthetic Huron Chain of Lakes Construct storm water wetlands wetland plants into the design value/habitat Create and maintain grassed Natural or constructed channels on farm lands established Huron Chain of Lakes waterways with suitable vegetation Treatment of sheet flow, improved infiltration, reduced erosion Install and maintain vegetated filter Strips of grass or other permanent vegetation designed to Slower runoff velocities, better infiltration, sediment and nutrient Huron Chain of Lakes strips treat sheet flow Streamside ecosystems managed for the enhancement of filtration Huron Chain of Lakes Install and maintain riparian buffers water quality Slower runoff velocities, infiltration, sediment and nutrient filtration Install and maintain bioretention Landscaping features in developed areas adapted to Huron Chain of Lakes systems provide onsite treatment Open channel management practices designed to treat Sediment and nutrient filtration, slower runoff velocities Huron Chain of Lakes Install grassed swales and attenuate storm water runoff Slower runoff, sediment and nutrient filtration, improved infiltration Replacement of turf grass with native tall grasses and Discourage geese- reduce E. coli, slower runoff, sediment & nutrient Huron Chain of Lakes Install pond buffer native plantings flowering plants filtration Practice agricultural conservation Establish and maintain vegetative cover, used primarily Huron Chain of Lakes cover on agricultural lands Slower runoff velocities, improved infiltration, reduced erosion Practice crop rotation w/ cover and Employ agricultural techniques that limit impacts on Huron Chain of Lakes mulch water quality Reduced sedimentation, and nutrient loadings Treatment, settling and storage of storm water. Aesthetic Huron Chain of Lakes Restore wetlands Rehabilitation of drained or degraded wetlands Vegetated depression typically near an impervious value/habitat Huron Chain of Lakes Install rain gardens surface to intercept storm water runoff Slower runoff velocities, infiltration, nutrient filtration Replace turf grass with shrubs and Use native grasses, shrubs and trees to create attractive Huron Chain of Lakes trees boarders Improved infiltration, slower runoff, nutrient filtration Evaluate areas for in-stream Installation and maintenance of in-stream structures to Huron Chain of Lakes restoration improve fish and wildlife habitat Physical or vegetative control measures to prevent or Improved habitat Huron Chain of Lakes Stabilization of soils and slopes reduce soil erosion Reduced soil erosion, improved surface drainage Promote storm water infiltration and A storm water device or system collecting runoff and Huron Chain of Lakes detention discharging it into the ground Improved infiltration, sediment collection and nutrient filtration Install and maintain infiltration A rock filled trench with no outlet that receives storm Huron Chain of Lakes trenches water runoff Reduced soil erosion, improved infiltration Huron Chain of Lakes Install and maintain vegetated roofs Structural addition of plants/soil over a traditional roof system Improved energy efficiency, reduction of storm water runoff Huron Chain of Lakes Reduce nutrients at permitted point sources Use best available technology (BAT) to remove pollutants from point source effluent Prevention of pollutants from entering the watershed 144
Watershed Plan BMP Title BMP Description BMP Outcome Huron Chain of Lakes Install grade stabilization culverts Install structures to control the grade and head cutting in channels (mostly agricultural) Reduces erosion and sedimentation Install and maintain catch basin Installation of additional sump chambers to enhance Huron Chain of Lakes inserts collection of solids Reduction of sediment in storm water Install and maintain porous Modular paving blocks with openings filled with sand or Huron Chain of Lakes pavement soil Two-chambered collection device consisting of a settling Reduction of surface runoff, improved nutrient filtration Huron Chain of Lakes Install and maintain media filters chamber and filter bed Reduction of sediment in storm water Install and maintain sediment Barriers, basins and other devise designed to remove Huron Chain of Lakes trapping devices sediment from runoff Reduction of sediment in storm water Repair misaligned/obstructed Coordinate townships and County efforts to address Huron Chain of Lakes culverts drainage problems Alter grading practices and examine surface options on Addresses changes in hydrology and maintenance Huron Chain of Lakes Stabilize road/bridge surfaces unpaved roads and bridges Reduce sediment pollution Mill Creek Restore wetlands Rehabilitation of drained or degraded wetlands Ordinance for wetlands not currently regulated by state Treatment, settling and storage of storm water. Aesthetic value/habitat Mill Creek Implement local wetland ordinances or federal authorities Protection of small and isolated wetlands Initiate hydrologic study and Comprehensive hydrology and hydraulic study in the Understanding precipitation, infiltration, surface runoff, flow rates and storage & better understanding of velocity, flow depth, flood Mill Creek hydraulic study watershed elevation, channel erosion Remove in stream structures and Removal of Dams and other obstructions like sediment Mill Creek obstruction islands, log jams, branches/trees Can solve soil erosion and flooding problems Implement natural features Protect local natural resources and direct development to Can be more protective than federal & state law to reflect local Mill Creek ordinances suitable areas priority Implement storm water & water Protects watershed regarding water quality, quantity and biological Mill Creek resource protection ordinances Regulations to guide property development integrity Construct and maintain storm water Manage storm water treatment onsite or per regional Reduce sediment, nutrient and flow issues associated with Mill Creek detention/ retention tributary area unmanaged storm water Construct/maintain wet detention Manage storm water treatment onsite or per regional Reduce sediment, nutrient and flow issues associated with Mill Creek ponds tributary area & create wetland unmanaged storm water Install and maintain bioretention Landscaping features in developed areas adapted to Mill Creek systems Construct and maintain infiltration provide onsite treatment Sediment and nutrient filtration, slower run-off velocities Mill Creek trenches Diverts storm water into a trench with no outlet Stores storm water runoff and allows for soil infiltration Install storm water Diverts storm water into a trench, basin, permeable Mill Creek retention/infiltration devices pavement for absorption into soil Open channel management practices designed to treat Stores storm water runoff and allows for soil infiltration Mill Creek Install grassed swales and attenuate storm water runoff Slower runoff, sediment and nutrient filtration, improved infiltration Reduce directly connected Directing flows from roof drains and paved areas to Mill Creek impervious surface area stabilized vegetated areas Reduction in storm water peak discharges, runoff volume and erosion Install and maintain extended wet Manage storm water treatment onsite or per regional Reduce sediment, nutrient and flow issues associated with Mill Creek detention ponds tributary area & create wetland unmanaged storm water Mill Creek Install and maintain rain gardens Vegetated depression typically near an impervious surface to intercept storm water runoff Slower runoff velocities, infiltration, nutrient filtration 145
