B.C. cities are bracing for the rising waters of a king tide that could put homes in low-lying areas at risk for flooding.

The City of Delta has built a concrete and sand berm to protect homes and streets along Boundary Bay, while Vancouver has laid sandbags along Locarno Beach to stop waters from flooding past Marine Drive when the next king tide hits around December 5.

“It’s hard to say what these storms will bring,” said Steven Lan, Delta’s acting city manager. “But we’re prepared, as you can see. We’ve had lots of experience with it.”

The king tide, also known as a perigean spring tide, happens when the moon and the sun line up, and their gravity pulls water levels higher.

Storms and waves on top of those higher waters can overwhelm coastal defenses and cause property damage.

In 2014, a storm that hit during a king tide washed out a 20-metre section of the seawall along Boundary Bay. One home was evacuated.

Two years before that, a West Vancouver arts centre was flooded, and Vancouver’s Kitsilano Pool was itself under water.This year, the king tide is predicted to last from Dec. 5 to 9, January 2 to Jan. 7, and January 31 to Feb. 4, according to the B.C. Storm Surge Almanac.
