The proposed action would: [1] remove the existing zones in the extreme southern end of Flagler County that are a part of the rule for Volusia County; and [2] establish new zones in this area and other portions of Flagler County that would be in effect only from May 1 through September 7. The proposed zones would include 2.7 linear miles of Slow Speed zones on the ICW. Zones would be established in the vicinity of the Hammock Dunes Parkway Bridge, in the general area between Silver Lake and the State Road 100 (Moody Blvd) Bridge (including Lehigh Canal), and in the southernmost roughly 2.1 miles of Flagler County.
