This has required a fundamental shift from a focus on protecting individual natural features to protecting the entire natural heritage system and its vital ecological functions. In turn, this has resulted in an increased emphasis on incorporating consideration of the natural heritage system into all aspects of land use planning, from official plan policies through to zoning and site plan and subdivision approvals. 1.2 Watershed planning is currently recognized as one of the most effective mechanisms for the protection, management and enhancement of the natural environment. It uses a holistic approach to managing all aspects of a watershed's natural heritage system, including hydrological resources (groundwater and surface water), terrestrial resources (wildlife habitat and habitat connectivity), aquatic resources and habitat (e.g. fish, streams, wetlands), and the inter-relationships that exist between these resources. Watershed plans are also locally based and therefore reflect, and are responsive to, the unique conditions including human land use,that exist within each watershed. 1.3 Both the Durham Region and the Clarington Official Plans include policies that recognize the importance of watershed planning to the protection and wise management of natural heritage resources, and support the preparation of multi- stakeholderwatershed planning studies. The Regional Official Plan, as well as area municipal official plans, require the inclusion of appropriate policies to implement individual watershed plans. 1.4 In 2002, the provincial government, through the Oak Ridges Moraine Conservation Plan, directed every upper-tier and single-tier municipality to prepare watershed plans for every watershed whose streams originate on the Moraine. In response to this legislative requirement, the Ganaraska Region Conservation Authority (GRCA), in partnership with the Region of Durham, the Municipality of Clarington and other watershed municipalities, has coordinated the preparation of watershed plans for Wilmot Creek, Graham Creek, and the Ganaraska River. In order to provide complete watershed coverage in Clarington, GRCA also prepared a joint watershed plan for three smaller watersheds (Lovekin Creek, Bouchette Point Creek, and Port Granby Creek) that arise south of the Oak Ridges Moraine on the Lake Iroquois Plain (see Attachment 1). 2.0 WATERSHED PLANNING PROCESS 2.1 The process for preparing a watershed plan involves eight steps, as follows: Step 1: Scoping Step 2: Characterization of the watershed system Step 3: Setting goals, objectives and working targets Step 4: Developing management alternatives Step 5: Evaluating management alternatives REPORT NO.: PSD-043-10 PAGE 3 Step 6: Selecting preferred management alternatives Step 7: .Finalizing targets Step 8: Developing implementation and monitoring plans. 2.2 Step 1 (Scoping) involves choosing a study area, identifying issues of concern and information gaps, and creating a Terms of Reference for the study. Step 2 (Characterization of the Watershed) entails defining the historical and current conditions of the study area (i.e. the watershed). GRCA completed the Scoping exercise and the ABC (Abiotic, Biotic and Cultural) Background Reports for each of the four subject watersheds in 2009. These background reports contain the scientific information and local knowledge necessary for the preparation of the actual Watershed Plans (Steps 3 to 8 of the process). 2.3 A successful watershed planning process is, by necessity, a cooperative process that involves a variety of governmental and non-governmental stakeholders. A Technical Review Committee was created to provide technical assistance to Conservation Authority staff in the preparation of the various watershed plans. Members on this Committee included Clarington Planning staff, Durham Region Planning staff, the federal Department of Fisheries and Oceans, and the provincial Ministries of the Environment and Agriculture, and Food and Rural Affairs among others. 2.4 Community Advisory Committees were also formed, with membership drawn from interested members of the local community. The role of these committees was to promote awareness of the watershed planning process, to solicit broader public input on issues within each watershed, and to comment on the recommended goals, objectives and management actions in the watershed plans. Opportunities for public and stakeholder input on the watershed studies occurred during 2009, including public open houses in Orono, Newcastle Village and Port Hope. 3.0 OVERVIEW OF THE WATERSHED PLANS 3.1 The Watershed Plans divide the watersheds into eight separate components to facilitate the presentation of information and the discussion of issues, as follows: • Groundwater quantity • Surface water quantity • Groundwater quality • Surface water quality • Aquatic habitat and species • Terrestrial natural heritage • Public health and well-being • Community heritage. REPORT NO.: PSD-043-10 PAGE 4 3.2 Issues/Opportunities. Goals. Obiectives and Management Actions 3.2.1 The discussion of each watershed component was, in turn, divided into a number of sub-categories, as discussed below. 3.2.2 Issues and Opportunities -These are current or future activities and conditions that currently or could negatively impact the watershed. For example, an issue identified with respect to Surface Water Quantity relates to the need to better understand natural flow variations in the various watercourses in the watersheds. 3.2.3 Goal.- A goal statement was created for each watershed component to identify a desired outcome to be achieved through the implementation of the watershed plan. For example, the goal for Surtace Water is "Maintain and improve the hydrologic function of the watershed". 3.2.4 Objectives -Objectives were created for each goal statement in order to facilitate and achieve the desired goal for the watershed component. All issues and opportunities identified in the Watershed Plan are addressed by the Objective statements. For example, one of the objectives for Surface Water Quantity is "Maintain and enhance the water balance and baseflow'". 3.2.5 Management Actions -Activities that need to occur were identified under each Objective in order to achieve the goal of each watershed component. Management actions are defined in four categories: Regulations and Planning, Stewardship, Education and Awareness, and Land Acquisition. Monitoring and Reporting are also listed as proposed management actions to assist in understanding how the implementation of the recommendations in the Watershed Plans is influencing the watersheds. The management actions most relevant to the Municipality are those listed under Regulations and Planning, which are primarily policies intended to be incorporated into municipal, Conservation Authority and .other agency planning and regulations documentation. To a lesser extent, some of the management actions listed under Stewardship are also applicable to the Municipality -for example, encouraging the adoption of urban land uses that increase groundwater recharge. As well, the Municipality is involved with and supports the Clean Water Healthy Land Financial Assistance Program, and GRCA's stewardship program. 3.2.6 For the most part, the same Goals, Objectives and Management Actions have been identified in each Watershed Plan. These are summarized on Attachment 2 to this report. REPORT NO.: PSD-043-10 4.0 CONCLUSION PAGE 5 4.1 The preparation of a Watershed Plan is only the first step in the ongoing process of managing and protecting the resources and ecological functions of a watershed. In order to be effective in achieving its stated goals and objectives, the management actions recommended by the Watershed Plans need to be implemented by the various stakeholders to the watershed planning process, including the Municipality of Clarington. As well as provincial legislation, the policies in the Durham Region Official Plan require the Municipality to incorporate appropriate policies into our Official Plan in order to implement watershed plans. 4.2 It is therefore appropriate that the Watershed Plans for Wilmot Creek, Graham Creek, Ganaraska River, and Lovekin, Bouchette Point and Port Granby Creeks be referred to Staff for detailed consideration through the ongoing Clarington Official Plan review process.
