OLYMPIA, Wash. -

More than 13,000 federally subsidized flood insurance policies in Washington state are facing hefty premium increases, despite a rate relief law signed by President Barack Obama.

In 2012, Congress passed a law requiring policyholders receiving subsidies to start paying rates based on the true risk of flooding at their properties. After public outcry over the premium hikes, Congress passed legislation earlier this month pulling back some of the immediate rate hikes.

However, approximately 1.1 million policyholders still will be hit with annual premium increases year after year, until the government is collecting what it needs to pay out claims.

In Washington, more than 9,100 homeowners face an annual increase of 18 percent. Nearly 4,000 businesses or second homes will see 25 percent hikes each year.
