Exhibit "D" <br />A Brazilian pepper stand on the southwest corner of the original property near Oslo Road and South <br />Vero Square Plaza was removed shortly after acquisition with the use of County mitigation funds. The <br />trailhead parking area was located in this area. Elsewhere on the original property, Brazilian pepper is <br />largely confined to areas along the mosquito impoundment dike. Brazilian peppers interspersed within <br />native plant community areas are treated with herbicide and left to deteriorate in place. Other areas <br />with Brazilian peppers, along impoundment dikes and canals, have periodically been mechanically <br />removed by IRCMD staff and/or County work crews. Periodically, County staff and ORCA volunteers <br />conduct exotic removal projects throughout the property, focusing on infestations of Brazilian pepper, <br />air potato and other Category I and II exotic plant species, listed by the Florida Exotic Pest Plant <br />Council (FL EPPC). <br />An exotic plant removal project was implemented on the Flinn Tract in 2006 and 2007, clearing <br />approximately eight acres of Brazilian pepper from transitional wetlands and maritime hammock <br />communities. The project was a wetland impact mitigation permitted by the SJRWMD, and is now <br />under regular monitoring by Bio -Tech Consulting, Inc. Monitoring will extend until 2010 or until the <br />mitigation success criteria have been met. Specific activities included hand clearing and herbicide <br />application of the exotic plants. The project was originally designed to remove only Brazilian pepper, <br />but other invasives have been treated as well. <br />IMPLEMENTATION <br />RESOURCE PROTECTION AND MANAGEMENT <br />Security <br />ORCA is open to the public from sunrise to sunset. The property boundary is partially fenced at this <br />time. Where security problems and encroachment from adjacent land is a problem, fencing will be <br />installed. Approximately 3,400 feet of fencing to address the encroachment issue is needed along the <br />boundary between the original property and the adjacent residential community to the west (see <br />Conceptual Development Plan). Security for the property is provided by the Indian River County <br />Sheriff's Office. <br />Water Resource Protection and Wetland Restoration <br />The Indian River Mosquito Control District is responsible for ongoing maintenance and management <br />of the mosquito impoundments on the ORCA property. The management plans for the impoundments <br />are included in the Appendix of this plan. County staff will continue to work with the Mosquito <br />Control District to manage mosquito control and wetland function in the impoundments. <br />County staff will continue to work with adjacent land owners and the Florida Department of <br />Transportation to protect and improve water quality entering the ORCA property. Stormwater <br />management improvements by FDOT will be considered during future reconstruction projects on US <br />1, since drainage from the state road is currently channeled through the ORCA property to the Indian <br />River Lagoon. <br />Additional wetland mitigation projects will be considered on a case-by-case basis by County staff , <br />subject to written approval by District land management staff, and with FIND staff when project areas <br />13 <br />
