Especially from Florida peninsula.

Do you mean new-new or since Hurricane Charlie new?

     Have you checked other companies? Some companies are looking to get out of Florida so they're jacking up their rates to get rid of customers. Or I should say that they're threatening the state with leaving, unless the state gives in and let's them drop coverage and so many deductibles and exemptions that anything and everything will be excluded from their coverage.

Been going on since hurricane Andrew .

what are some alternative to florida peninsula?

Was it because of the new 'adjustments' to the Flood Zones which now required thousands to pay for flood insurance even when they aren't in areas that flood.

  If the problem is that they're now tell you that you're now in a flood prone area then you should be able to contest it.  When my BIL built his home they told him that he was in a low-lying prone area area. He's has a canal behind his house and the water level in it is 12 feet below his property and the canal empties into a VERY large lake (LK Harris) less than a 1/4 mile away. Short of another ice age, there's no way in hell that that lake is going to rise 12 feet! And even that would only bring the water up to his property. It would take another 3 or 4 feet to flood it. By that time a GOOD bit of Florida would be under water!  He contested their claim and they dropped it so quickly that it was like it never happened!  Among other things several city and county officials live in his neighborhood and no one had ever told them that they were in a flood zone and they would not have taken it sitting down if they had!

  Sounds like it's time for you to go do your home work and then take the proof of your claim and go fight who ever is telling you that you're in a flood zone.   Or move.  Or pay off your house and tell the insurance company to shove it!
