Stormwater Management Master PlanThe term for the current permit has elapsed, but has been administratively extended by KDOW.MSD submitted a proposed Stormwater Quality Management Plan (SWQMP) in 2008 to KDOWfor the permit and is awaiting final approval.The SWQMP, which is planned to be updated once the MS4 permit is finalized, is a detailedbusiness plan MSD and its co-permittees intend to use as a tool to implement the MS4 permit.The intended purposed of the SWQMP is to improve water quality in local streams, creeks, andwaterways within Jefferson County. The expected water quality benefits include reductions inpollutants of concern and more closely meeting the Clean Water Act goals for water quality.1.4.3 Integrated Overflow Abatement Plan (IOAP)/Green InfrastructureThe IOAP is a long-term plan to improve water quality, control combined sewer overflows(CSOs), and eliminate sanitary sewer overflows (SSOs) throughout the county. The IOAP wasprepared in response to a consent decree with the EPA and the Kentucky Environmental andPublic Protection Cabinet. The IOAP is intended to improve water quality in both the localstreams in Jefferson County and the Ohio River. The expected water quality benefits includereductions in the peak levels of bacteria and a reduction in the amount of time that averagebacteria levels exceed water quality standards. For further information, copies of the IOAP canbe found on MSD’s website.As part of the IOAP, 115 potential green infrastructure projects have been identified throughoutthe county as of July 2010. Many types of green projects are being considered, such as bioswales,permeable alleys, pervious parking, and rain gardens. Currently, 20 projects have beenselected for construction and 95 other projects are being considered. A map showing thelocations of these projects is included as Figure 1.4.1.5 Watershed Master Plans1.5.1 GeneralThe management of stormwater drainage is recommended to be on a watershed-by-watershedbasis. Accomplishment of this approach shall be through the development of StormwaterManagement Master Plans. These plans document the hydrologic, physiographic, drainagecharacteristics, and planning tools pertinent to managing stormwater drainage in the watershed.Utilizing this information within the context of various policies, goals and objectives establishedfor the SMMP, specific “Action Plans” set forth recommended regional projects, specialregulations for development, and requirements for further updating and upgrading the planningdata and models.Further information specifically regarding the floodplain of each watershed, including number offloodprone buildings, development trends, critical facilities located in the floodplain, natural andbeneficial functions of the floodplain, and general flooding information can be found in theLouisville Metro Multi-Hazards Mitigation Plan.August 2010 Planning Methodology Page 18
