  • Fraser Valley Geotour: Bedrock, Glacial Deposits, Recent Sediments, Geological Hazards and Applied Geology: Sumas Mountain and Abbotsford Area
    Fraser Valley Geotour: Bedrock, Glacial Deposits, Recent Sediments, Geological Hazards and Applied Geology: Sumas Mountain and Abbotsford Area A collaboration in support of teachers in and around Abbotsford, B.C. in celebration of National Science and Technology Week October 25, 2013 MineralsEd and Natural Resources Canada, Geological Survey of Canada Led by David Huntley, PhD, GSC and David Thompson, P Geo 1 2 Fraser Valley Geotour Introduction Welcome to the Fraser Valley Geotour! Learning about our Earth, geological processes and features, and the relevance of it all to our lives is really best addressed outside of a classroom. Our entire province is the laboratory for geological studies. The landscape and rocks in the Fraser Valley record many natural Earth processes and reveal a large part of the geologic history of this part of BC – a unique part of the Canadian Cordillera. This professional development field trip for teachers looks at a selection of the bedrock and overlying surficial sediments in the Abbotsford area that evidence these geologic processes over time. The stops highlight key features that are part of the geological story - demonstrating surface processes, recording rock – forming processes, revealing the tectonic history, and evidence of glaciation. The important interplay of these phenomena and later human activity is highlighted along the way. It is designed to build your understanding of Earth Science and its relevance to our lives to support your teaching related topics in your classroom. Acknowledgments We would like to thank our partners, the individuals who led the tour to share their expertise, build interest in the natural history of the area, and inspire your teaching.

  • Final Report for Miracle Valley GW Study
    PITEAU ASSOCIATES GEOTECHNICAL AND HYDROGEOLOGICAL CONSULTANTS 215 - 260 WEST ESPLANADE NORTH VANCOUVER, B.C. CANADA - V7M 3G7 TEL: (604) 986-8551 / FAX: (604) 985-7286 www.piteau.com DISTRICT OF MISSION HYDROGEOLOGICAL INVESTIGATION FOR GROUNDWATER SUPPLY MIRACLE VALLEY, B.C. Prepared by PITEAU ASSOCIATES ENGINEERING LTD. PROJECT 3131 APRIL 2012 PITEAU ASSOCIATES ENGINEERING LTD. i. EXECUTIVE SUMMARY Piteau Associates Engineering Ltd. has been retained by the District of Mission to conduct hydrogeologic investigations at the Miracle Valley to explore the feasibility of supplying up to 210 L/s of quality groundwater for municipal water supply. Our investigations have included the construction and testing of two 200mm (8”) diameter test wells – TW11-1 at the south end of Burns Road, and TW12-1 at the north end of Stave Lake Road. The Miracle Valley Aquifer is a 10 km2 sand and gravel aquifer that is confined by a thick sequence of clay and sandy till. Primary sources of recharge include exfiltration from watercourses along the east side of the valley and downward infiltration of incident precipitation. Groundwater flow is interpreted to be northward above Hartley Road towards Stave Lake. South of Hartley Road, groundwater flows to the south/southwest and discharges to a number of spring-fed creeks. The results of aquifer pumping tests conducted with TW11-1 and TW12-1 indicate that aquifer sediments are highly permeable, and theoretical short-term yields for larger diameter (12” to 16”) pumping wells constructed in these areas are 124 and 360 L/s, respectively. It therefore appears possible to extract groundwater at 210 L/s from two or more wells at either location.

  • Hatzic Island
    HATZIC ISLAND Discussion Paper March 2018 Johannes Bendle, Planner I Fraser Valley Regional District Summary of Situation Development on Hatzic Island has occurred over time without a comprehensive planning framework. Much of the development on the Island pre-dates land use planning zoning regulations. Many older developments are at an urban density with simple on-site individual water and sewage systems. There are indications of variable contamination of the environment and drinking water. Furthermore, Hatzic Island is within the Fraser River floodplain and is also susceptible to localized flood hazards. Since the adoption of land use controls, policies and regulations have constrained subdivision, but has failed to address the environmental and health hazards or provide for effective management of construction and land use. The situation is compounded by the lawful non-conforming status and complex land tenure arrangements found on the Island. There is increasing pressure for recreational residential use and low cost residential accommodations. New approaches are needed to address environmental and health risks, and manage land use and development on Hatzic Island. Description Hatzic Island is located within Electoral Area “G” of the Fraser Valley Regional District (FVRD) on Hatzic Lake. Hatzic Island’s popularity as a recreational area and its evolution in use to a residential area, in conjunction with environmental constraints and concerns regarding water and sewage, has created challenges for the Island. This evolution from seasonal recreational use to permanent residential use has only exasperated existing challenges. The rising real estate costs in the Fraser Valley have arguably contributed to increasing permanent residential use on Hatzic Island as people seek out affordable housing options.

  • Report Prepared at the Request of Hatzic Prairie, Durieu, Mcconnell Creek Ratepayers
    Report prepared at the request of Hatzic Prairie, Durieu, McConnell Creek Ratepayers Association, in partial fulfillment of UBC Geography 419: Research in Environmental Geography, for Professor David Brownstein Thomas D'Hoore April 18, 2011 For too long, hard-working rural communities have bared the brunt of development. The interests of a few large companies have been protected over the rights of many. Disregard for rural residents has led to the degradation of their homes and resources across British Columbia. Given the small size, and limited access to information of many of these communities, formal action against industry is nearly impossible. The political clout of rural communities is waning, and the geographic dispersal of these communities makes organizing coherent political action that much more difficult. One such community is the Hatzic Valley. This research focuses on protecting drinking water in the Hatzic Valley. My goal is to assess whether or not Community Watershed Management Status is a viable means of protecting the groundwater resource in the region. This report highlights key issues in the history of the community; profiles the Hatzic Prairie, Durieu, McConnell Creek Ratepayers Association; describes the current state of water quality; and addresses the role of the Fraser Valley Regional District in order to establish the foundation for policy recommendations. Hatzic Valley is a rural community that lies just North of the Fraser River, about 80km east of Vancouver, BC. There are 1,339 residents, living in an area of 2,030 square kilometers.1 The upper slopes bordering the valley are generally used for forestry activities, while the lower slopes are mainly used for residential purposes.
