Escambia County Land Conveyance Act This bill authorizes Escambia County, Florida, to convey its interest in any part of the former Santa Rosa Island National Monument land that was conveyed to it by the federal government in 1947 to any person or entity, without restriction. The bill prohibits any person or entity holding a leasehold interest in such land from being required to involuntarily accept a fee interest to such land in place of the leasehold interest. The bill conditions such conveyance on requirements that: (1) all interest of Escambia County in any part of such land that is within the jurisdictional boundaries of Santa Rosa County, Florida, must be conveyed to Santa Rosa County within two years of the enactment of this bill; and (2) Escambia County must preserve in perpetuity the areas of the conveyed monument land that, as of this bill's enactment, are dedicated for conservation, preservation, public recreation access, and public parking. Santa Rosa County shall assume ownership of the non-federal land conveyed to it free of such restrictions. Santa Rosa County or any other person to whom such county reconveys such land may reconvey any part of it. Any proceeds from the conveyance of such land by either county shall be considered to be windfall profits that shall revert to the United States.
