In the unincorporated area, those <br />lands, located along both sides of the IRL, are designated "C-2" on the future land use <br />map. `C-2" designated lands may be developed at one (1) unit per 40 acres or used for a <br />density transfer of one (1) unit per acre to an upland site. <br />Most of the land in the unincorporated County within the CI IHA consists of residential <br />land with dcveloprnent potential and permitted densitics ranging from three (3) to ten <br />(10) units per acre. A substantial portion of this land is currently developed. Much of that <br />development took place at a time when the CIII-IA was more nar-owly defined as land on <br />the barrier island, east of the Coastal Construction Control Line (CCCL). <br />In the unincorporated area, the CHHA also contains a shall portion of the commercially <br />designated knid in three (3) areas. Those areas within the CHHA are: the Medical Node <br />Appendix A <br />
