Watershed Plan BMP Title BMP Description BMP Outcome Mill Creek Install and maintain vegetated roofs Structural addition of plants/soil over a traditional roof system Improved energy efficiency, reduction of storm water runoff Mill Creek Implement private roads ordinance Allows for roads to be narrower than county standards Reduction of impervious surface area minimizing runoff to watershed Establish flow limits in storm water NPDES could/should limit flow for permit holders no Mill Creek permits limit is currently established Limits will reduce hydrology damage associated with excess flow Implement alternative drain Look for opportunities to correct old drainage practices Mill Creek practices and rehab like tiled agricultures Restores hydrologic function Implement stream bank stabilization Improve stream bank structurally through engineers, Improves stream health if flow and erosion issues are addressed prior Mill Creek measures bioengineered, or biotechnical stabilization Streamside ecosystems managed for the enhancement of to implementation Mill Creek Install and maintain riparian buffers water quality Slower runoff velocities, infiltration, sediment and nutrient filtration Create and maintain grassed Natural or constructed channels on farm lands established Mill Creek waterways with suitable vegetation Install structures to control the grade and head cutting in Treatment of sheet flow, improved infiltration, reduced erosion Mill Creek Install grade stabilization culverts channels (mostly agricultural) Plant permanent vegetation cover on properties with Reduces erosion and sedimentation Mill Creek Utilize conservation cover exposed soil (primarily agricultural) Reduces soil/sediment run off and nutrient/nitrate issues/loadings Practice crop rotation w/ cover and Employ agricultural techniques that limit impacts on Mill Creek mulch water quality Reduced sedimentation, and nutrient loadings Install and maintain sediment Barriers, basins and other devise designed to remove Mill Creek trapping devices sediment from runoff Reduction of sediment in storm water Install and maintain catch basin Installation of additional sump chambers to enhance Mill Creek inserts collection of solids Reduction of sediment in storm water Mill Creek Control soil erosion Stabilize slopes and soils Prevents or reduces erosion due to storm water run off. Mill Creek Mill Creek Mill Creek Construct and maintain media/sand and organic filters High powered street and paved area sweeping Repair misaligned/obstructed culverts Mill Creek Stabilize road/bridge surfaces Mill Creek Practice nutrient management Construct and maintain waste Mill Creek storage facilities Mill Creek Mill Creek Install and maintain livestock use exclusion Install and maintain vegetated filter strips Construct variety of filters - usually two chambered sand or sand/peat mix Removes pollutants and particulates from storm water A management measure that involves pavement cleaning on a regular basis Reduction of sediment debris and pollutant export to receiving waters Coordinate townships and County efforts to address drainage problems Addresses changes in hydrology and maintenance Alter grading practices and examine surface options on unpaved roads and bridges Reduce sediment pollution Employ Generally Accepted Agricultural Management Practices (GAAMPs) on agricultural land Construct barriers, embankments, and temporary waste storage facilities for agricultural uses Construct barriers like fences to keep livestock 25 feet from banks Strips of grass or other permanent vegetation designed to treat sheet flow 146 Controls or limits potential pollutant/nutrient exposures from agricultural land use Reduces exposure pathways prior to land application of nutrients/fertilizers Protects riparian vegetation and banks from animals, limits waste exposure pathways Slower runoff velocities, better infiltration, sediment and nutrient filtration
Watershed Plan BMP Title BMP Description BMP Outcome Mill Creek Mill Creek Mill Creek Mill Creek Implement native landscaping ordinance Encourage use of plants adapted to this geographic area Improved storm water infiltration , soil stabilization and habitat Native vegetation restoration program Identify and eliminate illicit discharges Implement golf course nutrient management Mill Creek Implement phosphorus fertilizer reduction ordinances Regulate selection, use, storage and disposal of fertilizers Require regular inspection, maintenance, and repair of Mill Creek Implement septic system ordinances septic systems by ordinance. Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Mill Creek Implement natural features ordinances Utilize in stream habitat restoration techniques Construct and maintain media/sand and organic filters Install and maintain oil and grease traps Reduce directly connected impervious surface area Provide technical consultation and study, locate, coordinate, and implement native landscaping projects Reestablishes native species and restores riparian habitat Conduct storm water sampling program and inspections to trace illicit connections Identification of illicit discharge sources Practice turf management, wetland restoration, watercourse buffers and environmentally sensitive purchasing and nutrient management - Certification is available through MSU Extensions Reduces negative effects of golf courses on local watersheds Protect local natural resources and direct development to suitable areas 147 Reduction of nutrients entering watershed reducing algal blooms and fish kills Prevents, detects, and controls spills, leaks, overflows, and seepage of septic systems Can be more protective than federal & state law to reflect local priority Create channel blocks, boulder clusters, covered logs, tree cover, bank cribs, and other restoration techniques Corrects and improves fish and wildlife deficiencies Construct variety of filters - usually two chambered sand or sand/peat mix Removes pollutants and particulates from storm water Install oil and grease traps for industrial, maintenance, vehicle washing, and restaurants Directing flows from roof drains and paved areas to stabilized vegetated areas Removes high concentration of petroleum products, grease, and grit, by gravity and coalescing plates Reduction in storm water peak discharges, run-off volume and erosion Construct and maintain infiltration trenches Diverts storm water into a trench with no outlet Stores storm water run-off and allows for soil infiltration Install and maintain bioretention systems Landscaping features in developed areas adapted to provide onsite treatment Sediment and nutrient filtration, slower runoff velocities Implement municipal well field protection Complete implementation of wellhead protections plans Protects drinking water resources Monitor for water quality, quantity, biota Survey species of concern distribution and management Increase watershed education and ethic Implement a coordinated information campaign Mill Creek Enhance site plan requirements Collect a consistent dataset of water quality parameters, biotic indicators, and stream flow Establishes a baseline for implementing recommended BMPs Conduct study to examine condition of plant and animal species of concern like freshwater mussels Many activities include: Adopt-a-stream, school education, stewardship network Target nonpoint source pollution prevention through traditional marketing methods Species can serve as bellwether for progress on watershed management Identifies responsible parties, promotes community ownership, identifies problems/solutions, integrates public feedback Prevents pollution from entering system by motivating behavioral modifications Review floodplain, soil types, landmark trees, groundwater recharge areas, etc. Assures environmental responsible development
