BOOK 9 Hu 121 <br />their management alternatives, that is, can the beach be used for <br />disposal or does one of the centralized sites have to be used; and <br />establish a site bank. <br />Mr. Roach estimated four sites will be needed in Indian River <br />County for 24 miles of waterway. They will be looking at about 24 <br />different properties. Each site will be analyzed using 21 <br />different criteria, restrictions or concerns, which basically break <br />into engineering and operational criteria, environmental criteria, <br />and socio-economic or cultural concerns. It is then narrowed down <br />to a primary and secondary site in each dredging area. He <br />indicated he would know the volume of dredge material by the end of <br />the month. - <br />After completion of the first phase of identifying sites, Mr. <br />Roach detailed the phase two process when a full -range of analysis <br />is done for the sites before they are purchased or put into the <br />long-range system. He advised that 45 sites have already been <br />acquired by the State. <br />Mr. Roach then explained the commercial, private, and national <br />defense reasons for keeping the ICW navigable for the ever- <br />increasing numbers, sizes, and drafts of the vessels traversing it. <br />Chairman Macht asked if Fritz Island was big enough to make an <br />impact on the disposal, and Mr. Roach advised they had some <br />previous discussions with representatives of Johns Island about <br />doing some land exchanges, so it has been looked at and he thought <br />it was somewhere in the vicinity of 70,000-80,000 cubic yard range. <br />Their minimum size site is typically 30 acres, because the buffer <br />area takes half of the acreage. <br />Chairman Macht believed the whole system was over 300 acres <br />and that it had been totally invaded by exotics. He inquired if it <br />would be practical to remove all that vegetation and re -plant with <br />native species if they acquired Fritz Island. <br />Mr. Roach indicated it would and they had already done a lot <br />of re -planting work in that regard citing projects in Dade and Palm <br />Beach Counties. He wanted to emphasize that the installations <br />would be permanent facilities, so if Fritz Island were selected as <br />one of the sites, they would remove the exotics and bring in native <br />plant species. Having recently funded a native species program at <br />the Environmental Learning Center, the source for new plants would <br />be quite near. He felt it could work very well for everyone in the <br />community. <br />26 - <br />September 19, 1995 <br />
