Just as an update:
We are dealing with a PRP Eligibility Extension Policy on this. I have seen where buildings are eligible for an extension of the policy with the lower risk for two years after date of map revision. Per the insurance company, map revision was in 2012 (I'm trying to verify that with our flood vendor), but they are saying the program states that "This procedure also applies to policies previously issued under the Preferred Risk Policy Eligibility Extension that are renewing on or after April 1, 2015". Does anyone recognize the April 1 date for flood? I'm just trying to get a handle on this so I can understand it better.
