Local preparation context for San Francisco, CA
San Francisco homeowners often face heavy rainfall events and stormwater drainage challenges. Preparing the exterior and lower floors before a storm can reduce how much water gets inside.
Walk the exterior and look for clogged gutters, full downspouts, ponding near the foundation, and yard debris that could block storm drains.
Inside-the-home checklist
Test your sump pump by pouring water into the pit. Confirm any battery backup holds a charge. Move stored items off basement and garage floors.
Photograph rooms, electronics, and any valuables. Gather a small flashlight, charged phone bank, copies of insurance information, and important medications in a portable bag.

Frequently asked questions
Is it worth sandbagging a residential home?
It depends on local risk and the type of flooding expected. Where appropriate, sandbags can slow shallow water; they are not a complete solution for significant flooding.
Should I shut off utilities before evacuating?
Follow local guidance. Many sources recommend turning off electricity to flood-prone areas if you can safely do so.
What if water enters anyway?
Move to safety, document the damage when it is safe, and contact a restoration contractor and your insurer.
