SAN ANTONIO -

First it was the water, now it's the deluge of expenses for people who's homes were ravaged by the weekend rains. 

Many had no flood insurance.

"The damage can be thousands of dollars, thousands of dollars," said Donna Pundt, account executive with Grona Boles Martin Bloxsom Insurance.

Her office is now fielding phone calls and questions about flood insurance and what it covers.

"It covers rising waters, which the average homeowner's (policy) does not," she said.

Although 80  percent of people know a standards homeowners policy does not cover flood damage, only 13 percent of homeowners have a flood policy, according to a Bankrate survey.

For flood coverage, homeowners must buy a separate policy from FEMA's National Flood Insurance Program (NFIP), through their insurance agent or company. A mortgage company may even require it, depending on the property's flood risk.

Many people are unaware of their flood risk, whether it's high, moderate or low, according to the Bankrate survey.

One website to check local flood maps is www.BexarFloodFacts.org.   

The cost of flood insurance depends on location and elevation. Generally, the higher the flood risk, the higher the premium.

The average flood policy is $400 a year, according to Pundt.

Premium for a very low risk area could be as low as $129, according to FEMA.  High risk areas in flood plains can see premiums of a few thousand dollars.

Regardless of the premium, NFIP policies covered building damage up to $250,000 and contents up to $100,000. If a homeowner needs more coverage, excess can be purchased through their insurance company.

There is a 30-day waiting period for flood policies to kick in.
