Long Beach faces long-term flood risk from sea level rise, and its storm drain system — some of it a century old — can't handle today's intense storms. Upgrading it could cost hundreds of millions of dollars, with a master plan update going out to bid this spring.

The city is shifting to proactive sandbag distribution with pre-filled bags at multiple locations, and urging residents to sign up for Alert Long Beach and build emergency kits.
