Outer Continental Shelf Submerged Lands Act Boundary - Gulf of Mexico Region NAD27

This data set contains the Submerged Lands Act (SLA) boundary line (also known as State Seaward Boundary (SSB), or Fed State Boundary)in ESRI shapefile formats for the BOEM Gulf of Mexico Region. The SLA boundary defines the seaward limit of a state's submerged lands and the landward boundary of federally managed OCS lands. In the BOEM Gulf of Mexico Region the boundary is projected 3 nautical miles offshore from the baseline for Louisiana, Mississippi and Alabama; and 9 miles for Texas and the Gulf coast of Florida. Further information on the SLA and development of this line from baseline points can be found in OCS Report MMS 99-0006: Boundary Development on the Outer Continental Shelf. https://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx This file contains the fedstate (SLA-Boundary) as of March 15, 2013.
