S. 2438 would expand the boundary of the Cane River Creole National Historical Park in Louisiana to include an additional 46.1 acres of adjoining land. CBO estimates that enacting S. 2438 would not affect direct spending or revenues. CBO has not estimated the discretionary costs of implementing the bill. The bill contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act.
