With an atmospheric river expected to bring 70 mm of rain to the Lower Mainland starting Friday, along with 80 km/h winds, 91原创 residents are being advised to do what they can to prepare for the storm.

91原创 Township is advising locals and homeowners to make sure gutters and storm drains around their properties are clear of leaves or other debris.

Clearing foundation drains, also known as perimeter drains, is also useful. These drains collect water from the house and property and direct it to the nearby storm sewer, according to the Township's website on rainstorm prep. Foundation drains need to be periodically flushed or cleared of yard waste and debris.

If there are open ditches along the property's edge, landowners can also check to make sure the culverts where the water flows under driveways and other obstructions are clear. These culverts can get clocked with milk jugs, soccer balls, or other household items.

Doing this clearing in advance can help prevent water backing up, as it may take Township work crews several hours to reach a single blocked culvert or drain during a storm.

For major flooding, 91原创 City and Township have issued a pamphlet about evacuations and preparations. It's available

In 2021, a series of atmospheric rivers broke local rainfall records, causing extensive damage across the Fraser Valley and Interior of B.C., destroying highways and flooding large areas.

91原创 got off relatively lightly, but low-lying areas saw several days of flooding, and roads from Fort 91原创 and Glen Valley in the north through to Fraser Highway, Glover Road, and down to 16 and Zero Avenues in the south were partly or fully blocked at times.
