Priority Actions for Shingle Creek Subwatershed (Table 66).
Link to this table.

Priority Timeframe1 Action Estimated Effectiveness of Practice2 (up to) Estimated Magnitude in Watershed Implementation Cost3
High Identify and map potential bacteria hotspots Staff time
High Update and enforce pet waste ordinances ~23,000 acres developed land but target near stream first Staff time
High Conduct public outreach to ensure that pet owners pick up pet waste and comply with pet waste ordinances Staff time
High Direct flow pathways between contributing areas to infiltration/treatment basins or away from impervious areas to prevent direct pathway to receiving waters
High Develop, implement, and enforce a program to detect and eliminate illicit discharges
High Inspect/monitor stormwater outfalls to reduce dry weather flow Staff time
Medium Install Filtration/Biofiltration BMPs where feasible 35% $8,000-20,000/ac
Low Install filter strips/buffers near waterbodies to deter waterfowl from congregating and conduct public outreach on wildlife feeding 91% ~53 acres (assume 11 miles of stream; 20ft buffer) $600-1,000/acre of buffer
Low Conduct septic system inspections as warranted and bring all imminent threat to public health septic systems into compliance with ordinances 100% ~22 systems $200-300 (inspection) $7,500 per system (if replacement required)
