As shown in Figure 1, the Town is bounded by the District of North Saanich on the north, west and south, and by Haro Strait on the east. Town of Sidney Page 1 2014 Community Risk Assessment History – Sidney began as a milling town more than 100 years ago. The town’s economic base has since evolved from logging, fishing and farming to light manufacturing, retail sales, and tourism. The Town of Sidney was incorporated as North a village on September 30, 1952. It 1 Saanich Town of covers an area of 714 hectares. Sidney Sidney’s role on Vancouver Island strongly reflects its access to transportation. Sidney lies along the major vehicle route connecting the Capital Region with the BC Lower Mainland, through the BC Ferry terminal at Swartz Bay. The Town also serves as the terminus for the Washington State Ferries’ route between Vancouver Island and Anacortes in Washington State. With Central several boat marinas, Sidney is both Saanich home to and a destination for pleasure boat owners and travelers. The Town also lies immediately adjacent to the Victoria International Airport, which supports a number of aviation and Figure 1. Location of Sidney on the Saanich Peninsula industrial businesses.

The eastern seashore provides access to the beaches on Haro Straight, with views of the Southern Gulf Islands, San Juan Islands, and Washington State. Sidney occupies 3.6 km of waterfront, of which 2.4 km has been developed as a linear park. The Town of Sidney, like the rest of the Capital Region, resides in one of the most active seismic zones in North America. Earthquake threats include the Cascadia Subduction Zone off the west coast of Vancouver Island, and shallower earthquakes near Georgia Strait and Puget Sound. Steep slopes are not a problem in Sidney; the Ministry of Environment notes low risks from slope failure for Armstrong Point and Thumb Point at Tsehum Harbour. Although Sidney has no formally designated floodplains, some areas are subject to Figure 2. Geographic Landscape of Sidney localized water intrusion during (source: CRD Maps) heavy rainfall events. The coast is subject to tidal ranges that, when combined with storm conditions, can lead to localized shoreline flooding. The principal tsunami threat in the Sidney area represents the potential effects of subduction earthquake. A tsunami created elsewhere in the Pacific Basin would, at most, affect low- lying coastal areas in Sidney similar to a large winter storm. Implications of Physical Setting: Earthquake ranks among the hazards of greatest concern.
