Congressional Budget Office Cost Estimate: H.R. 585, Anchorage Land Conveyance Act of 2013 [open pdf - 23KB]
From the CBO (Congressional Budget Office) estimate: "H.R. 585 would require the Secretary of the Interior to convey the reversionary interest of the United States in three acres of land to the city of Anchorage, Alaska. Under current law, the city holds title to those lands and will retain title as long as the lands are used for public purposes. If the city stops using the lands for such purposes, title would revert back to the federal government. Based on information provided by the city of Anchorage, CBO expects that, under current law, the city would continue to use the affected lands for public purposes and hold title to those lands over the next 10 years. Furthermore, under the bill, any administrative costs associated with conveying the reversionary interest in those lands would be paid by the city; therefore, CBO estimates that implementing the bill would have no effect on the federal budget."
