Summaries of CSA International's Representative New Projects

Mining Federal OCS Sand Sources Off Florida

CSA International was awarded a 32-month contract in April 2000 by the U.S. Department of the Interior, Minerals Management Service (MMS), International Activities and Marine Minerals Division (INTERMAR). CSA is serving as prime contractor for the study titled "Environmental Surveys of Potential Borrow Areas on the East Florida Shelf and the Environmental Implications of Sand Removal for Coastal and Beach Restoration." The purpose of the project is to provide information that can be used in a National Environmental Policy Act (NEPA) document (Environmental Assessment or Environmental Impact Statement) for decision making concerning potential impacts associated with dredging sand from the Federal Outer Continental Shelf (OCS) for beach nourishment. Federal OCS sand resource areas of interest are offshore Martin, St. Lucie, Indian River, and Brevard Counties. CSA is responsible for overall project management and the biological component of the study. Biological field surveys will be conducted in September 2000 and May 2001 to collect data concerning infauna, epifauna and demersal fishes, hard/live bottom, sediment grain size, and water quality. Benthic literature and data will be summarized, and assessments will be made of the potential impacts relative to benthic organisms and recolonization. CSA will synthesize information concerning the spatial and temporal occurrence of pelagic, endangered, and threatened species and assess potential impacts and dredging windows. The physical processes component of the study includes modeling of wave modifications and assessments of sediment transport processes and patterns to evaluate potential impacts. Coordination will occur with the Florida Geological Survey (FGS). A Technical Report, Executive Summary, Technical Summary, Non-Technical Summary, refereed scientific publication, and slide set will be produced. Results of the study will be presented at an MMS Information Transfer Meeting and a technical conference.

Biological Report for a Borrow Area Off Gulf Shores, Alabama

CSA International prepared the "Biological Report for the Offshore Borrow Region Associated with a Beach Restoration Project at the City of Gulf Shores, Alabama." The report provided sections concerning the project purpose and need, description of the proposed action, existing benthic (infauna, epifauna, and demersal fishes) and pelagic (zooplankton, squids, sea turtles, and marine mammals) environments, benthic and water column field surveys, potential impacts, conclusions, literature cited, and survey data appendices.
