Flood insurance takes 30 days to start; San Jose urges residents to check flood zones before El Niño storms

SAN JOSE — Most homeowners and renters insurance does not cover flood damage, and a new federal flood policy usually takes 30 days to start, according to FEMA’s National Flood Insurance Program.  San Jose staff are urging residents to check their flood zone and consider coverage before El Niño storms, an Oct. 29 memo to the City Council says.

Homes need not be next to a creek to flood, the memo says; it lists flood-prone areas along Coyote Creek, the Guadalupe River and Upper Penitencia Creek.  The council votes Tuesday on declaring a local emergency, and forecasters expect light rain Friday.

Look up your address: Type your street address into the city’s Flood Hazard Zones map, at https://experience.arcgis.com/experience/eeaf9ca34be34769b552282ef83d6bd3, to see which FEMA flood zone your home is in. FEMA’s Flood Map Service Center, at https://msc.fema.gov/portal/search, does the same for any U.S. address and shows the official federal flood map. The city’s flood line, (408) 535-7803, or floodzoneinfo@sanjoseca.gov, answers questions and provides copies of elevation certificates, which can lower premiums.

Federal policies cover up to $250,000 for a house and $100,000 for belongings; renters can buy belongings coverage alone.  Rates are the same from any participating insurer.  Policies do not cover temporary housing, landscaping, fences or items kept in basements.

San Jose’s floodplain rules earn policyholders a 15% discount in high-risk zones and 5% elsewhere, FEMA data show.

The state Insurance Department says standard policies may cover some wind-driven rain and fallen-tree damage.
