Mary inherited a parcel of land on the outskirts of an lowa town that has been in her family for generations. Even though her family has never utilized the land, she now wishes to build, along with her brothers, a small family restaurant on the inherited land. Mary applies for a building permit, and finds out that the lowa legislature recently passed a law preventing further construction on land designated as "protected wetlands." Her land, it turns out, is now designated as "protected wetlands," and she is denied a building permit for any future building on the property.

What protection(s) and amendments) are involved?

Should the State of lowa pay Mary for the inability to use her land?
