A1.01 FAMILIARIZATION Prior to the commencement of the Engineering Design, the Consultant shall obtain copies of the municipality s Design Criteria Manual and Standard Detailed Drawings to familiarize himself/herself with the requirements of subdivision design in the municipality. Meetings shall be held with the Township Engineer and Director of Public Works and the Township Planning Department to discuss areas of preliminary concern and other data prior to commencement of the engineering design. A1.02 ENGINEERING REQUIREMENTS FOR DRAFT PLAN APPROVAL A preliminary Functional Servicing Report must be submitted to the Township Engineer for review and acceptance. This report must be presented in a readable, comprehensive and professional manner. The Report must be signed and sealed by a Professional Engineer. This Functional Servicing Report (FSR) shall contain the following information as a minimum and be submitted in duplicate. (a) The Draft Plan The Draft Plan must be in a form acceptable to the Planning Department of the Township of Adjala-Tosorontio and the County of Simcoe. A reduced size (8½x11) copy of the draft plan shall be included in the FSR. (b) Contour/Drainage Plan This plan must be at a scale of no larger than 1:1250 giving contour lines at sufficient intervals to permit assessment of existing surface drainage patterns. This plan is to extend to the limits of the drainage area to be served by proposed sanitary and storm sewer systems, including lands beyond the boundaries of the subdivision. For large external areas Contour plans at a larger scale may be provided. All elevations are to refer to Geodetic Datum. Contours established from air photo interpretation will not be permitted. A-1

7 A1.02 ENGINEERING REQUIREMENTS FOR DRAFT PLAN APPROVAL (cont d) (c) General Plan of Services This will be a plan based on the Draft Plan and must schematically show the proposed storm and sanitary sewer systems and their connection to existing systems. This plan is to be accompanied by preliminary engineering calculations indicating the quantity of flows at the connection to existing systems and/or at proposed outfalls. Consideration must be given to the whole catchment area to ultimately be developed. Blocks and easements for drainage systems shall also be shown. Preliminary road profiles must also be identified in the FSR. The method of treatment and disposal of sewage shall be provided and an outline of the actual design shall be presented, including calculations and relative size of the treatment facilities. (d) Drainage/Stormwater Plan When a natural drainage channel passes through and is affected by the subdivision, drawings must be submitted to indicate the location and typical cross-sections of the existing channel of any proposed changes. A preliminary stormwater management plan and report will be required by the Township of Adjala-Tosorontio in accordance with Section C 2.05 of the document. An erosion-sediment control plan will be required. The Consulting Engineer must submit an outline of the erosion-sediment control plan in accordance with Section C All proposed stormwater controls shall be in accordance with the Nottawasaga Valley Conservation Authority requirements and their preliminary assessment and approval of the design is required. (e) Water Systems The FSR shall outline the proposed source of water and the method of distribution.

36 SECTION C - STORM DRAINAGE AND STORMWATER MANAGEMENT C1.00 DRAINAGE POLICIES C1.01 DRAINAGE OBJECTIVES The Township of Adjala-Tosorontio has set the following objectives for drainage management within its boundaries: That post-development runoff not exceed the pre-development runoff. Reduce to acceptable levels, the potential risk of health hazards, loss of life and property damage from flooding. Reduce to acceptable levels, the incidence of inconvenience caused by surface ponding and flooding. Ensure that any development or redevelopment minimizes the impact of change to the groundwater regime, increased pollution, increased erosion or increased transport, especially during construction. Maintain the natural stream channel geometry, insofar as it is feasible with achieving the above objectives. Encourage groundwater replenishment by infiltration where possible and practical. C-1

37 C2.00 ATTAINMENT OF DRAINAGE OBJECTIVES C2.01 GENERAL The Township of Adjala-Tosorontio standards are to be part of an overall storm water plan involving MOE requirements - Appendix A and the N.V.C.A. Storm Water Management Guidelines - Appendix B. C2.02 MAJOR AND MINOR SYSTEMS In general, the Township of Adjala-Tosorontio supports the concept of drainage having two separate and distinct components - the minor drainage system and the major drainage system. The minor system comprises swales, street gutters, ditches, catchbasins and storm sewers. The major system comprises the natural streams and valleys and the manmade channels and ponds. C2.03 RUN-OFF QUALITY CONTROL The Township requires developers, contractors and builders to plan and execute their operations so as to minimize sediment and debris pickup and transport to water bodies. The degree of control and methods used must meet the regulations and guidelines of the MOE, MNR, MTO and local Conservation Authorities. On site inspection of the facilities and will expect all erosion control works are to be properly maintained throughout the duration of the project to the satisfaction of regulatory agencies. C2.04 MASTER DRAINAGE PLANS The Township requires a Master Drainage Plan for all proposed urban developments. The primary purpose of the Master Drainage Plan is to define the effects of urban development and to determine the solution that is compatible with the objectives for the watershed. C-2

38 C3.00 MAJOR SYSTEM C3.01 HAZARD LANDS AND FLOODLINES The Township of Adjala-Tosorontio requires that Hazard Lands be clearly defined on all watersheds and that no development, other than necessary access or services, be located therein. The Township also requires that the floodplains that would result from the 1:100 and Regional storms be defined for predevelopment and post development conditions. C3.02 DETENTION PONDS Detention Ponds shall be designed so as to minimize any adverse effects to the environment as well as ensuring the safety of local residents. Ponds that exceed 3.0 metres in depth shall have terraced slopes to facilitate maintenance of the facility. The minimum slope of the bottom of the pond shall not be less than 1.0 percent. Under no circumstances should the contours of the land in such detention ponds be altered after construction without notifying the Township of Adjala- Tosorontio and the appropriate Conservation Authority. It must be agreed by all concerned that such modification will have no detrimental effect on the stormwater management. C3.03 OUTLET STRUCTURES FROM PONDS Where a detention pond is proposed for quality control on a watercourse, the outlet structures must be designed as much for ease of operation as for hydraulic efficiency. The designer should always consider the possibility of a plugged outlet and should design a maintenance feature for drainage. The inlets and outlets must be protected to prevent child and major debris access. The area at the downstream end must be protected against erosion by channel lining and/or energy dissipater. The Township of Adjala-Tosorontio requires that the Consulting Engineer submit an outline of his proposed erosion sediment control plan with the first submission of Engineering Drawings. This may contain any or all of the following measures: sediment traps or temporary detention ponds seeding of topsoil stockpiles isolated stripping of development lands vegetation screens erosion control (silt) fence. C-3

39 C4.00 MINOR SYSTEM C4.01 WATERSHED AREA The contributing watershed area shall be determined from the contour plans and shall include all areas that naturally drain into the system and any fringe areas not accommodated in adjacent drainage systems, as well as other areas which may become tributary by reason of regrading. C4.02 STORM DRAINAGE PLANS EXTERNAL AREAS A plan shall be prepared to a scale dependent on the size of the watershed area, to show the nature and extent of the drainage of the lands surrounding the development site. The area to be developed and all existing contours used to justify the design shall be clearly shown. This plan shall be prepared and submitted to the Township Engineer at the functional report stage. INTERNAL DRAINAGE PLAN All internal storm drainage plans shall be prepared to a scale of 1:1000 and shall include all streets, blocks, lots and easements. The proposed storm sewer system shall be shown on this plan with all manholes numbered consecutively from the outlet. The manholes shall be the tributary points in the design and the area contributing to each manhole shall be clearly outlined on the plan. The area in hectares and the runoff coefficient shall be shown in a circle within the contributing area. In determining the contributing area to each manhole, the proposed lot grading must be considered to maintain consistency in the design. The length, size and grade of each section of storm sewer shall also be shown on the storm drainage plan. Large arrows should depict the overland flow route. C4.03 RAINWATER LEADERS Rainwater leaders on all single family and semi-detached residential units shall be discharged onto splash pads and shall be constructed in a manner so as to not interfere with adjacent properties. The only exception shall be where discharge to soak-away pits or trenches forms part of an overall stormwater management scheme. C-4
