Layer: Sand Resources (ID: 5)

Name: Sand Resources

Display Field: State

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: *Proven - Resource areas whose thickness and lateral extent have been fully determined through design-level geotechnical and seismic coverage. Generally reserved for (but not limited to) areas that have already been authorized as part of a lease. *Potential - Resource areas whose existence has been verified through sufficient geotechnical and geophysical data. Thickness and/or lateral extent has not been fully determined. All areas have some combination of geotechnical and geophysical datasets (vibracore, bathymetry, sidescan, and seismic). *Unverified - Resource areas hypothesized to exist on the basis of indirect evidence (seismic profiles, bathymetry, or sidescan sonar). Inferred sediment types, unit thicknesses and lateral extents have not been confirmed through direct sampling methods. *Unusable - Resource areas that as a result of additional surveys, prior dredging activity, or infrastructure development are not (or no longer) suitable for future dredging; this designation should not be considered terminal and is subject to change. The Sand Resource Areas layer contains delineations of areas in the Outer Continental Shelf (OCS) where there is some likelihood that a usable sand resource exists. The sand resource areas were identified and characterized during governmental reconnaissance- and design-level studies where various geological (e.g. sediment cores, sediment profile images, etc.) and geophysical (e.g. high-resolution swath bathymetry, side-scan sonar, seismic reflection profiles, magnetometer surveys) data were collected in OCS focus areas. The intent is to build on the dataset as updates from new reconnaissance- and design-level studies become available; pre-existing reports will be added to the dataset as time permits. Attribution of each resource generally consists of study location, approximate areal extent, approximate volume, sediment properties, and confidence level (see attribute definition for detailed explanation) of the delineation. Delineations are not guaranteed to be exact and may contain estimate boundaries delineated based on visual interpretation of drawings and descriptions found in study documents and reports. Likewise, the character of sediment deposits qualifying as sand resource areas varies with region and prospective applications for use. If a sand resource area is eventually deemed suitable to serve as a restoration resource for a given site, then entities may enter into a Negotiated Non-Competitive Lease or Memoranda of Agreement with the Bureau of Ocean Energy Management (BOEM), in order to dredge sand, gravel or shell resources from the sand resource area. Section 8 (k) of the OCS Lands Act (OCSLA) as amended by Public Law 103-426 (enacted in 1994) gives BOEM the authority to negotiate an agreement for the use of OCS sand, gravel and shell resources for use in: (1) a project for shore protection, beach restoration, or coastal wetlands restoration undertaken by a Federal, State, or local government agency; or (2) for use in a construction project funded in whole or part by or authorized by the Federal government.
