Approximately 3,772 acres within the RBNERR boundaries are leased to the Department of Environmental Protection (DEP) by NAS, The Nature Conservancy, and CSF. State-owned lands, including 70,000 acres of submerged lands and approximately 22,928 acres of acquired lands, are held in fee simple title by the Board of Trustees. Approximately 13,300 additional acres within the boundaries were acquired by the state as part of a settlement agreement with the Deltona Corporation. Parcels totaling approximately 500 acres represent privately-owned inholdings within RBNERR. DEP has proposed for NOAA consideration that the boundaries of the RBNERR be expanded to incorporate adjacent state-owned coastal and submerged lands. DEP has designated all tidally connected waters within the boundaries of RBNERR and Cape Romano/Ten Thousand Islands Aquatic Preserves as Class II and Outstanding Florida Waters (OFW). OFW designation implements the state's highest standards for proposed developments, and does not allow for direct discharges that would lower ambient water quality, or indirect discharges that would significantly degrade water quality.
