Building in Flood Zone Questions

[Jim Goebel]

Questions below

1. Approx how much extra does flood insurance run?
2. In terms of building on the land (I'm an engineer) I'm wondering if there are major hurdles I should be aware of OTHER Than the increased costs of building - more related to regulatory, financing, and other risks.  I'm confident I can design what we need to withstand a flood (even large flood) from a construction perspective.  I'll need to run the numbers on that but I'm confident I can handle the design and engineering, and construct-ability.
3. Is bringing in tons and tons of dirt from another location really an option for us?  I know most jurisdictions have regulations about removing dirt (have to submit a site runoff / remediation plan) , but I'd bet we could relocate dirt from way out in the country without any issues. 
4. Does the FEMA map get redrawn every so often, if say we were able to do substantial site work to get our elevation to a point where we are no longer in the flood plain, to build?

For now, that's a good starting point for a discussion, I think.
