Coastal barrier resources system mapping process
The Coastal Barrier Resources Act of 1982 (P.L. 97-348) established the Coastal Barrier Resources System (system), a 452,834 acre system of undeveloped, unprotected coastal barriers along 666 shoreline miles of the Atlantic Ocean and Gulf of Mexico coasts. Within the 186 unites of the Coastal Barrier Resources System, most Federal expenditures that encourage development are prohibited. Section 10 of the act directed the Department of the Interior (DOI) to conduct a study and prepare a report to Congress on the Coastal Barrier Resources System. The report, delivered to Congress in December 1988, recommended additions to, or deletions from, the Coastal Barrier Resources System, and listed modifications to the boundaries of system units. The DOI's recommendations, if passed by Congress, would add about 790,884 acres and 423 miles of shoreline to the Coastal Barrier Resources System. The coastal barriers included in the Coastal Barrier Resources System by Congress in 1982 were designated based on definitions and delineation criteria development by the DOI in 1981-82. The criteria used by the DOI to delineate barriers included in the 1988 recommendations to Congress differed from those used in 1981 in several respects, reflecting advances in the scientific understanding of coastal barriers, and the functional requirements of a good definition. I outline the mapping criteria used in 1981-82 and in 1984-87 during the Section 10 study. I also discuss some of the problems encountered in consistently identifying and delineating features across a heterogeneous national coastline, and I comment on future reinventories of coastal barriers.
