Five-Year Implementation Plan November 2002 Executive Summary In May 2002, the GVWD Board adopted the Watershed Management Plan that applies to Crown and private lands held by the GVRD within the Capilano, Seymour and Coquitlam watersheds. The overall Goal in this Plan is “Watersheds that provide clean, safe water and are managed and protected as natural assets of the highest importance to the Greater Vancouver region.” To achieve this overall Goal, the Board adopted the following five Principles to guide the development of the Plan. 1. The primary purpose of Greater Vancouver’s watershed is to provide clean, safe water. 2. The watersheds will be managed to reflect and advance the region’s commitment to the environmental stewardship and protection of those lands and their biological diversity. 3. The region’s Management Plan will be based upon the minimum intervention absolutely necessary to achieve the Board’s objectives. 4. The Management Plan will contain policies to return areas disturbed by human activities as close as possible to the pre-disturbance state consistent with the primary goal of protecting water quality. 5. The decision making process will be transparent and open to the public. The Plan describes nine implementation programs that are consistent with the five Principles in the area of water monitoring and forecasting, forest ecosystem management, fire management, erosion control, road network, water system infrastructure, communication and education, watershed security and emergency preparedness. The purpose of the Five-Year Implementation Plan is to provide the necessary guidance to ensure that management activities are implemented to reflect the management strategies as described in the Plan. The Five-Year Implementation Plan describes the proposed management activities over the 5-year course of the Plan. The Five-Year Implementation Plan will be updated in each successive year of the Plan. 1. Water Monitoring & Forecasting Implementation Program Objective: Verify that the watersheds will continue to provide an adequate supply of clean safe water for the water system. Activities: a) Maintain and operate water monitoring sites for water quantity and water quality purposes, including: four snowpack stations, three alpine reservoirs, seven hydrometric river stations, four reservoir turbidity stations, and two road surface erosion monitoring stations. b) Compile and analyze data from the stations listed above for operational and planning functions. c) Install reservoir water quality stations in the Coquitlam reservoir during 2002 and 2003. i Five-Year Implementation Plan November 2002 d) Upgrade the existing reservoir turbidity stations to include additional water quality parameters during 2003 and 2004. e) Upgrade the existing hydrometric river stations to include additional water quality monitoring starting with the Seymour stations in 2003. f) Monitor and assess the hydrometric river stations to review the effectiveness of the stations, and the analysis of data collected during storms. 2. Forest Ecosystem Management Implementation Program Objective: Minimize the amount of human induced disturbances to the forest ecosystem. Activities: a) Update the watershed inventory database from recent watershed activities. b) Develop and implement a biological diversity index during 2003. c) Produce habitat maps to stratify the wildlife scat sampling for the analysis of protozoan parasites during 2003-2004. d) Continue to review land use plans associated with lands adjacent to the watersheds and the potential implications of any proposed developments. e) Review the ecosystem restoration and the best management practices utilized at the sites developed for the Cleveland Dam East Abutment Seepage Control Project. f) Monitor and document trends of ecosystem health including terrestrial and aquatic communities. 3. Fire Management Implementation Program Objective: Suppress wildfires only when necessary to ensure water quality, protect public safety and property, and maintain air quality. Activities: a) Utilize models to assess the effects of wildfire on water quality parameters. b) Implement the wildfire management zones. c) Continue to develop and implement wildfire prevention strategies. d) Collect fire weather data and install five additional fire weather stations in the designated biogeoclimatic units. e) Calculate daily fire danger ratings for the biogeoclimatic units and the fire management zones. f) Respond to wildfires in a safe, timely and effective manner as required. ii Five-Year Implementation Plan November 2002 4. Erosion Control Implementation Program Objective: Minimize the impact of soil erosion on the quality of the water entering the water distribution system. Activities: a) Develop a decision tool system to assist staff in determining appropriate erosion control responses in order to be proactive in preventing sources of sediment entering the water intake, the beginning of the water distribution system. b) Develop preparedness and inspection programs so that mitigation measures can be applied quickly. c) Review and monitor the effectiveness of erosion control projects completed in 2001-2002. 5. Road Network Implementation Program Objective: Reduce the amount of roads in the watersheds to a level consistent with the Goal and Principles of the Watershed Management Plan. Activities: a) Undertake road maintenance activities such as roadside brushing, grading and drainage structure maintenance as required. b) Conduct annual assessments of roads to identify problems that may have developed during storms. c) Utilize a risk management approach to complete the road deactivation schedule. d) Implement and further develop best management practices for the road network. e) Monitor and evaluate the road maintenance and deactivation activities. 6. Water System Infrastructure Implementation Program Objective: Provide infrastructure for the storage, transmission, and treatment of the water supply while conserving watershed resources to the greatest extent possible. Activities: a) Prepare the soil disposal sites in Capilano watershed for the water treatment construction projects from 2003 to 2006. b) Upgrade the log booms and related infrastructure for managing wood debris in the Capilano and the Seymour reservoirs over the next few years. c) Undertake the seismic upgrade of the Seymour Falls Dam scheduled for 2004 to 2008. d) Determine suitable soil disposal sites, aggregate sources and rock quarries for the potential seismic upgrade of the Coquitlam Dam by BC Hydro. e) Improve the access to and from the alpine reservoirs with trails and helipads. f) Monitor and evaluate the use of best management practices to protect watershed resources. iii Five-Year Implementation Plan November 2002 7. Communication and Education Implementation Program Objective: Develop and maintain confidence and trust that the GVRD is managing the watershed resources in an environmentally responsible and cost-efficient manner. Activities: a) Implement communication and education initiatives that will foster public trust that the watersheds are being managed in accordance with the Watershed Management Plan. b) Inform consultation participants of upcoming public meetings, tours and information on the watersheds. c) Facilitate watershed stewardship groups to record biological and physical parameters within the watersheds. d) Further develop public education programs regarding the water system for the public and educators. e) Increase the content of the watershed information on the GVRD website. f) Develop a watershed research protocol to facilitate and encourage appropriate research activities in the watersheds. 8.
