The purpose of the proposed rule making action is to improve protection of manatees and manatee habitat in Broward County by amending the existing regulations that establish safe havens and limit allowable motorboat speed in portions of the county. These actions are being proposed after considering: [1] new information, analyses, and reports that have been collected, performed, or prepared since the existing zones were established; and [2] recommendations made by the Broward County Local Rule Review Committee that was formed pursuant to Section 379.2431(2)(f), F.S. The effect of the action would be to amend the zones that establish safe havens and limit allowable motorboat speed in portions of the county and to revise other provisions of the rule. Adoption of the proposed changes would add 22 minutes to the roughly four hours it currently requires to transit the county in the Intracoastal Waterway (ICW) during cold season weekdays, with nominal or no change during other times. The changes would have minor or no impact on the water in many locations because of existing boating safety zones that are more restrictive.
