POLICY PURPOSE: Concise, easy-to-understand statement, which explains the objective or philosophy underpinning the policy . This policy serves as a decision support tool as well as a methodology for the prioritization of works outlined in the Integrated Stormwater Management Master Plan (ISWM-MP). 2. DEFINITIONS: Unusual or specialized language, acronym, jargon or unique application of words. Stormwater “” - refers to rainwater and melted snow that flows over roads, parking lots, lawn and other sites in rural and urban areas. Stormwater Management “” - refers to practices which help to minimize the impact of polluted runoff flowing into watercourses, control the rate at which, or prevent, flooding from occurring and reduces the strain that stormwater places on municipal infrastructure. Low Impact Development “” - is an innovative stormwater management approach with a basic principle that is modeled after nature: manage rainfall at the source using uniformly distributed decentralized micro-scale controls. 3. SCOPE: Statement as to whom the policy applies, as well as exceptions and the ramifications of non-compliance, if any and deemed appropriate to include. 15 of 18 6 - 15 POLICY APPLIES TO THE FOLLOWING: All Employees This policy applies to all staff involved in any form of decision making related to any form of construction on municipal and private land. This includes but is not limited to: Engineering Facilities Management Operations – Roads and Traffic Operations – Environmental Services Transportation Services Building Planning Economic Development 4. POLICY CONTENT: Policy details, including specific roles and responsibilities relating to the policy. A.Stormwater Infiltration in the Context of Source Protection Planning This component defines where and how infiltration based stormwater management controls, commonly referred to as Low Impact Development (LID) controls, can safely be planned and constructed in the context of the approved source protection planning policy under the Clean Water Act. Developed in consultation with the Region of Waterloo staff and the Ministry Of Environment and Climate Change, this component of the policy acknowledges that the use of infiltration practices to reduce runoff and restore natural hydrologic processes is crucial to maintaining and improving the City of Kitchener’s natural water systems, maintaining the viability of local stormwater infrastructure, and contributing to climate change adaptation & mitigation strategies. As the implementation of infiltration practices becomes more prevalent, the City of Kitchener has a duty to protect local groundwater resources by implementing a land use-based stormwater infiltration framework which is developed based on a sound understanding of identified and future risks. Sites with high risk activities are generally discouraged from incorporating LID techniques that utilize infiltration as its primary function for sensitive drainage areas and require the proponent to prepare a Pollution Prevention Plan and/or Risk Management Plans as part of SWM Reporting requirements. Spill prevention and management are a central focus of such plans. Also identified within the Implementation Plan are the infiltration opportunities and constraints and lists of acceptable practices within various land-uses ranging from Residential, Mixed Use, Commercial, Industrial Employment, Institutional and Open Space and Natural Heritage Conservation as well as local, minor and major roadways within the City of Kitchener. B.Stormwater Volume Criteria and Targets This component outlines the minimum stormwater volume criteria as well as outlines the application of general stormwater management targets as part of: 16 of 18 6 - 16 New development, Redevelopment, reurbanization and residential intensification, and Linear projects (roadways, trails and transit infrastructure etc.). As part of this component, all sites within the City of Kitchener are required to: flood control and erosion Continue to control off-site runoff for per the approved watershed, subwatershed, master drainage plans, Environmental Impact Statement (EIS), Provincial Policy and Guidelines or other area specific studies. Special Policy Areas which address known or flood prone areas would remain in effect. infiltration targets Continue to achieve to maintain the existing water balance per current approved and future subwatershed plans. The Development Engineering section will identify relevant subwatershed plans and policies. water quality Control for (pollutant loadings) in accordance with current MOECC guidelines to ‘Enhanced-Level 1’ protection as defined in the 2003 Stormwater Management Planning & Design Manual. Retain a minimum of 12.5mm of runoff from the all surfaces on the entire site and to enroll in the City of Kitchener Stormwater Utility Credit program. Retention can be a combination of infiltration, evapotranspiration or rain water re-use (also known as rainwater harvesting). All volume retained on-site will be counted towards achieving flood and erosion control, water quality control as well as credits toward existing infiltration targets. In all cases, the targets as specified in this component shall be superseded by more stringent targets as developed by the MOECC or through future Watershed Studies, Subwatershed Studies, Master Drainage Plans, Environmental Impact Statement (EIS) and/or other area specific studies such as GRCA Wetland Policy. C.Stormwater Management Fee A Stormwater Management Fee (formerly Cash-in-lieu) has been established such that a development proponent shall provide a designated financial contribution at the current per hectare rate as defined by the City of Kitchener, as amended from time to time where the Stormwater Infiltration in the Context of Source Protection Planning requirements of the and the Stormwater Targets and Volume Criteria are not be fully achieved. This fee will be applied towards off-site stormwater management elsewhere in the city, in conformance with the recommended approaches of the Integrated Stormwater Management Master Plan (ISWM-MP). Funds will be collected by the City of Kitchener SWM Utility until such time as a suitable project or program is identified for partial or full funding. Sites with Restrictions For all sites regardless of perceived constraints, the proponent shall be required to fully comply with the appropriate volume control targets described above. Should pre-consultation with City of Kitchener engineering staff and/or pre-design investigation by the proponent and reviewed by the City Engineer identify that volume targets are not achievable; the proponent must consider and present the merits of relocating project elements to address varying soil conditions and other 17 of 18 6 - 17 constraints. Site constraints which may result in the City permitting alternatives to the above prescribed volume targets are based on: i.Shallow bedrock, ii.High groundwater, iii.Contaminated soils (i.e. Brownfields) iv.High Risk Site Activities v.Prohibitions: Issue Contributing Areas (ICA) and or WHPAs with a vulnerability score equal to or greater than 8 vi.Restrictions: including WHPAs with a vulnerability score of 2 to 6 inclusive On sites where the proponent cannot implement the required volume control to the Maximum Extent Possible or MEP as confirmed by the City of Kitchener Development Engineering, the site is required to contribute to the Stormwater Management Fee at the current per hectare rate as amended from time to time. 5. HISTORY OF POLICY CHANGES There are two types of policy updates. 1) “Administrative Updates” are done to reflect the current corporate structure and job titling and do not need Council or CLT approval. 2) “Formal Amendments” are major changes to the intent and purpose of the policy and require Council or Corporate Leadership Team (CLT) approval. Administrative Updates The date (yyyy-mm-dd) and a short annotation on the nature of the change to reflect the current corporate structure i.e. Departmental re-organization / Titling changes / Standing Committee restructuring. Formal Amendments The date of the resolution passed by Council or CLT, for example, “2020-01-20 - As per Council/CLT resolution” Click here to enter text. 18 of 18 6 - 18
