EXECUTIVE SUMMARY: The system-wide monitoring programs recommended within the Blair, Bechtel, Bauman Creeks (BBB) Study and the Upper Blair Creek Functional Drainage Study (FDS) has been underway in Blair Creek since 2006, undertaken by GRCA on behalf of the City of Kitchener, in addition to ongoing monitoring undertaken by three (3) of the four (4) main development proponents (Hallman, Monarch, Activa) since approximately 2007 relating to each individual development. The primary goal is to monitor and evaluate the overall health of the Blair Creek ecosystem. The secondary goal is to demonstrate that it is possible for environmentally responsible development to occur. The purpose of this first Upper Blair State of the Watershed (SOW) report is to document baseline environmental conditions, determine the nature of any observed impact on Blair Creek due to ongoing urban development in the East Study Area, assess the operational effectiveness of the monitoring program, and prioritize which monitoring parameters will assist in future monitoring efforts to develop an enhanced understanding of the state of the watershed. Based on pre-construction monitoring, Upper Blair Creek can be characterized as a very healthy creek. It has very low Total Suspended Solids (TSS) levels at all stations along Blair Creek with little variation throughout the year. At a minimum, targets for future monitoring have generally been proposed to reflect Maintenance of the status quo (existing conditions). Further, increased importance on erosion and sediment control during construction will ensure the creek and surrounding environment doesn’t suffer from the impacts of development. BACKGROUND: 2 The Blair Creek is a 18.4 km(1840 ha) watershed which spans the City of Kitchener, Cambridge and the 2 Township of North Dumfries. Agricultural land uses dominate the upland, headwater areas *** This information is available in accessible formats upon request. *** Please call 519-741-2345 or TTY 1-866-969-9994 for assistance. 3 - 1 of the Blair Creek Subwatershed. Blair Creek is a well-defined, perennial water course which is groundwater fed and sustains brook trout populations and other aquatic species. Many of the streams within the Blair Creek watershed are bounded by provincially significant wetlands and areas of natural and scientific interest. Blair Creek outlets to the Grand River at the Village of Blair, approximately 9 km downstream of the City of Kitchener Municipal boundary (at Hwy 401). The Upper Blair Creek subwatershed is located near the southwest boundary of the City of Kitchener and represents the headwaters of the Blair Creek system. The Upper Blair Creek subwatershed is further delineated into two (2) study areas: The East Study Area 1.- represents the lands located to the east of Reidel Drive and generally reflects the Doon South Community Plan – Phase 2 Area (current Study Area). The West Study Area 2.- represents the lands located to the west of Reidel Drive which are generally undeveloped. REPORT: Future State of the Watershed reports are scheduled to be completed every five (5) years. Of particular interest to the Region of Waterloo, City of Kitchener and the GRCA are: 1) Changes to flow regime impacting stream stability; 2) Thermal impacts to Blair Creek and associated habitats; 3) Sediment release, loadings and construction erosion and sediment control issues; and 4) Groundwater recharge. Evaluating the state of environmental and urban (East Study Area) features and functions within the Upper Blair Creek subwatershed area provides the Region of Waterloo, City of Kitchener and the GRCA with a benchmark tool for assessing watershed health. This vital information about the entire Upper Blair watershed area will not only provide decision makers, planners, and practitioners with defensible information needed to manage watershed resources in an effective and integrated manner, but also demonstrate that environmentally-responsible development can occur. Development in the West Study Area is contingent upon demonstrating that there have been no negative impacts on the Blair Creek as a result of the development in the East Study Area (Stantec Consulting Ltd., 2009). The objective of this first Upper Blair SOW report is to document and assess pre-construction conditions (baseline conditions) based on the monitoring data collected since 2006 against which future conditions can be evaluated (during and post-construction/development). Accordingly, to meet project objectives, the SOW report completed the following tasks: Reviewed all relevant background reports, monitoring programs and data. Defined existing conditions and assessed the approach and methodology used in the current monitoring program for the collection of existing conditions data. Developed a framework for project goals, objectives, indicators and targets. Evaluated the existing conditions in relation to the specific targets. Recommended an integrated monitoring program which refines the current program and integrates the proposed monitoring with the developed targets. Recommendations include specific areas within the current monitoring program that should be modified, remain the same or have flexibility going forward; and Provided recommendations in regards to sediment management during construction activities. ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN: The recommendation of this report supports the achievement of the City’s strategic vision through delivery of core service. 3 - 2 FINANCIAL IMPLICATIONS: The total cost of preparing the SOW report was $126,853.80 (inclusive of HST) and was paid for from funds in the annual Upper Blair Creek Monitoring account. Although increased system-wide City/GRCA monitoring is recommended in the SOW report, the current annual DC funding adequately covers the increased cost. No changes to annual budget requirements are anticipated for Upper Blair Creek Monitoring. COMMUNITY ENGAGEMENT: INFORM – This report has been posted to the City’s website with the agenda in advance of the council / committee meeting. COLLABORATE – A stakeholder committee was formed to assess the report findings including staff from Engineering, Environmental Planning, Region of Waterloo, and the GRCA. CONCLUSION: In conclusion, staff recommends that the Upper Blair Creek State of the Watershed Report dated February 10, 2016, prepared by Aquafor Beech Ltd, be received.
