Some shorelineareas have flood line mapping to the 1 in 100 year storm event. The Town shallcontrol stormwater runoff from new development sites in order to attenuate topredevelopment levels for the 1 in 2 through 1 in 100 year storm event, and shallregulate land uses within the limit of the Regional Storm as set out in Section 3.7 andbased on mapping provided by the Conservation Authorities.7.2.2 Runoff quality and quantity shall be addressed for all storm events.7.2.3 Due to historic development in the floodplain in the existing shoreline and settlementareas along Lake Simcoe and Cooks Bay, releasing of water from upstreamstormwater management ponds can lead to flooding downstream through the existingcommunities. In such areas, the municipality will explore means of addressing thismatter through such efforts as increased stormwater detention, diversion ofstormwaters or establishment of municipal drainage easements. Master DrainagePlans for new growth areas shall also address this matter and identify means tomitigate flooding caused by stormwater management pond releases.7.2.4 All new developments shall incorporate generally accepted Best ManagementPractices, which shall be the highest level determined to be technically andeconomically feasible, and shall meet the following criteria:i) no net reduction in surficial aquifer recharge or discharge;ii) minimize potential for contamination of groundwater and surface water;iii) minimize alterations to the natural drainage boundaries;iv) no creation of new flood or erosion problems or aggravation of existing flood orerosion problems;109Adopted July 26, 2006 Approved by OMB May 2009, March 2010 & April 8, 2011
