i) demonstrates general conformity with the recommendations of the Alcona North MasterDrainage Plan;ii) identifies where deviations are warranted, if any;iii) provides supporting technical analyses for appropriate location, sizing and design ofproposed storm water management facilities;iv) provides further detail on water quality objectives set out under the Lake SimcoeProtection Plan;v) assesses downstream erosion criteria;vi) provides further detail on the recommended means to reduce downstream as set out inthe Master Drainage Plan and means of implementation by the developmentcommunity;viii) demonstrates how an integrated treatment train approach will be used to minimizestormwater management flows and reliance on end-of-pipe controls;ix) demonstrates how anticipated changes in the water balance between predevelopmentand post-development will be minimized, andiix) demonstrates how anticipated changes in phosphorous loadings between predevelopmentand post-development will be minimized.15.9.3 Master Hydrogeological Studya) A Master Hydrogeological Study shall be prepared, to the satisfaction of the Town inconsultation with the LSRCA, for the entirety of the Secondary Plan Area. It shall besubmitted for approval prior to submission of draft plan of subdivision applications and shallbe based on terms of reference approved by the Town in consultation with the LSRCA,which addresses, but is not limited to, the following matters:i) a pre and post development water budget based on the land use plan;ii) analysis of the impacts of soil compaction on groundwater recharge;iii) identification of infiltration areas and areas contributing to infiltration areas;iv) identification of mitigation measures to maintain pre-development infiltration anddischarge including an assessment of how the use of infiltration areas can bemaximized in the design of the draft plans of subdivision;v) assessment of potential dewatering requirements;vi) identification and evaluation of methods and mechanisms that work towardsmaintaining the hydrologic function to ensure the sustenance of and no negative impactto the adjacent provincially significant wetland;vii) assessment of the impact on the water table of other natural heritage features, as wellas base flow to watercourses and means to mitigate the impacts;viii) further assessment of the aquifer vulnerability in the secondary plan area in the contextof the observed elevated nitrate level in the deep monitor BH6-1 and recommendationsfor reducing or eliminating the potential for groundwater contamination;ix) recommendations for a monitoring programme to address monitoring during and afterconstruction; andx) assessment of risk to the Stroud Municipal Wells for the northwestern edge of thesubject lands based on the land uses proposed for that area.January 2012 19
