The Shore Placement Areas feature class was created to represent the locations where sand or sediment placement is planned or has occurred as part of a coastal nourishment project and at least in part utilizing BOEM-authorized Outer Continental Shelf (OCS) sand / sediment sources for project construction. Each polygon feature illustrates the approximate lateral extent of placement associated with each project and contains attributes with supplemental information associated with project construction (e.g., BOEM OCS lease number, placement time range, placement volume, location/beach name (shore ID), planned vs actual mileage of placement, comments on ). In certain instances, project construction was completed utilizing sediment from the OCS and from state waters (landward of 3-nautical mile Submerged Lands Act Boundary). Thus, all shore placement polygon features do not represent areas exclusive to the placement of Outer Continental Shelf (OCS) sediment but rather represent an approximation of the entire placement area for the specified time range/construction event. Similarly, some placement features represent projects for which OCS sand was authorized for use but were not constructed prior to the expiration of the BOEM lease agreement. These features have a value of '0' in the 'placement volume' and 'actual miles restored' attribute fields and are also noted in the 'comments' field. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Shore Placement Areas feature class contains polygons representing approximate locations along the U.S. coastline where dredged material from the Outer Continental Shelf (OCS) has been placed as part of a project for shore protection, beach restoration, coastal restoration, or construction project undertaken by a Federal, State, or local government agency. These locations mainly include (but are not limited to) beaches that require shoreline stabilization and beach nourishment in order to reduce future coastal storm flooding and erosion, and to provide cultural, economic, recreational, and environmental habitat benefits. Placement areas for dredged OCS material are specifically defined in every Negotiated Non-Competitive Lease or Memorandum of Agreement with Bureau of Ocean Energy Management (BOEM) which authorizes contracted entities to dredge sand, gravel, or shell resources from the OCS. 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 restoration undertaken by a Federal, State, or local government agency; or (2) for use in a construction project funded in whole or in part by, or authorized by, the Federal government. Planned and/or as-built project placement locations are typically provided to the BOEM within or as an attachment (e.g. as-built survey drawing) to the lease agreement and post-construction/project completion reports. The polygon extents are not guaranteed to be exact and may contain estimate boundaries or generalized locations where as-built survey data were not available. Attribution consists of OCS lease number, project ID, Shore ID (placement area location or beach name), placement (construction) start and end dates, placement volume, the number of linear miles of coastline restored, and supplemental comments that provide additional context regarding the placement/construction event. This dataset will receive regular updates as new OCS leases are added or renewed and OCS sediment is allocated to planned placement sites along the U.S. coastline.</SPAN></P></DIV></DIV></DIV> |
