==Design Information==
* Consistent hydrology modelling to be utilized for each development application and/or consistent with MESP/MSP/Studies.
* Supporting information has been included for all modelling parameters and calculations.
*Stage-Storage-Discharge calculations provided for each SWM facility including design information on control and emergency overflow weirs.
*Flow and storage summary tables provided which reference the associated drainage area, catchment ID, outlet(s) and differentiate between controlled and uncontrolled areas.
*Identify and show seasonal high groundwater levels in report and on drawings;
*Per MOECC SWM manual, 2003 (i.e. Drainage area, required volume, slopes, forebay, etc.);
*The SWM report and drawings are to include a table summarizing required storage, provided storage and associated elevation and flow for the permanent pool, 25mm (extended detention), and 2 through 100 year return period storm events where applicable for each facility;
*An operations and maintenance manual should be included in the SWM Report for all LID facilities in accordance with municipal requirements;
*Complete information on proposed manufactured treatment devices is to be provided including current status under ETV protocols;
*An operations and maintenance manual is to be provided that includes a maintenance schedule;

2.2. Quality Control Section
• Level of Protection.
• Drainage Area to Facility in hectares.
• Percentage Impervious – total and directly connected areas.
• SWM Facility Monitoring and Maintenance Requirements.
3. Hazard Land Management
• Regional event and 1:100 year flood lines under existing and proposed conditions shown on appropriate plan drawings.
• Valley top of bank, stream erosion, steep slope allowances and meanderbelt assessed (confined stream systems only).
• Wetlands and required setbacks determined and identified on plans.
• Meanderbelt assessment and/or setback determined and identified on plans.
• Wave uprush and/or wind setup elevations calculated (Lake Simcoe Shoreline).
• “Limit of development” shown on plans.
• Survey and floodplain mapping submitted (As per minimum requirement in Appendix K).
• Hydraulic modelling and analysis including digital files (As per minimum requirements identified in Appendices C, I and K).
4. Other
Upon approval of the SWM design, a digital copy of the stormwater drainage plan is to be submitted including the location and size of the SWM facility in GIS format.
