11. Project Identification  Flood control projects  Project list provided by Town Staff  Feedback from residents (surveys and public meetings)  Hydrologic and hydraulic modeling results  Water quality projects  GIS layers (aerial photography, land use, stormwater inventory, topography)  Field reconnaissance  Flood control project locations  Flood control projects  Project list provided by Town Staff  Feedback from residents (surveys and public meetings)  Hydrologic and hydraulic modeling results  Water quality projects  GIS layers (aerial photography, land use, stormwater inventory, topography)  Field reconnaissance  Flood control project locations

12.  26 total projects proposed  19 projects proposed to reduce roadway, structural, and property flooding and provide water quality treatment, if feasible  7 projects proposed as water quality retrofits to predominantly treat areas draining to Town maintained outfalls  Projects will reduce the amount of pollutants reaching critical waterbodies  26 total projects proposed  19 projects proposed to reduce roadway, structural, and property flooding and provide water quality treatment, if feasible  7 projects proposed as water quality retrofits to predominantly treat areas draining to Town maintained outfalls  Projects will reduce the amount of pollutants reaching critical waterbodies Capital Improvement Plan

14.  Flood control projects reduce flooding by:  Providing drainage where no drainage system currently exists  Increasing capacity of drainage systems that are currently under capacity  Reestablishing compromised drainage systems  Providing water quality treatment where feasible using vegetative conveyance, BMPs, or other treatment devices  Flood control projects reduce flooding by:  Providing drainage where no drainage system currently exists  Increasing capacity of drainage systems that are currently under capacity  Reestablishing compromised drainage systems  Providing water quality treatment where feasible using vegetative conveyance, BMPs, or other treatment devices Capital Improvement Plan
