Richmond, British Columbia is on Lulu Island, the larger of the two red islands

Lulu Island is the name of the largest island in the estuary of the Fraser River, located south of Vancouver, British Columbia. The island is made up of the city of City of Richmond, while a small section at the eastern tip, known as Queensborough, is part of the City of New Westminster.
Lulu Island is situated between the two principal arms of the Fraser River estuary across and downstream from the City of New Westminster. The Middle Arm of the Fraser River separates it on the northwest from Sea Island, the site of Vancouver International Airport, which, despite its name, is also part of the City of Richmond. At the western edge of the island lies Sturgeon Bank, a large sandbank which falls off into the Strait of Georgia on its western edge.
The island enjoyed good connections to the new port city of Vancouver thanks to the Lulu Island & Steveston Railway line of the British Columbia Electric Railway, which began at what is today the north end of the Granville Street Bridge. The route of the Lulu Island Railway is today the so-called Arbutus Corridor, which runs west through Kitsilano before turning south to Kerrisdale and Marpole before crossing the North Arm of the Fraser to reach Lulu Island and the City of Richmond.
The southwestern corner of Lulu Island is home to Steveston, a fishing port and former cannery town, now a busy tourist centre that has a history interconnected with that of the Japanese-Canadians prior to their internment to the Interior during World War II.
The Eburne Swing Bridge has been removed (2015) and this leaves remaining trackage on the Richmond side of the river orphaned.
The Arbutus Corridor trackage has been removed (2016) and is now a Greenway for cyclists and pedestrians.
Because the island is composed partly of glacial silt brought down by the Fraser River, there is a fear of liquefaction of its sands if a tremor with sufficient intensity were to shake it. In such an eventuality, it is anticipated that localized areas, specifically in the vicinity of the present-day mouth of the Fraser River, could experience seismic liquefaction failure and collapse westward into the Strait of Georgia, potentially impacting the adjacent river entrainment works and possibly some navigational aids. Additionally, statically-triggered liquefaction failures have been documented in this area, highlighting the extremely loose localized soil conditions, as well as the high potential for associated slope instability and mass wasting.
The island is also fully diked to protect it from potential flooding during the annual spring freshet on the Fraser. Some of the island is below sea level, and river level, and there is an extensive drainage and pumping system to prevent flooding during heavy rain.
