This rule amendment extends one (1) zone and widens five (5) zones in the Florida Intracoastal Waterway in Pinellas County. It changes rule language to reflect historical marking of two (2) additional zones, removes the 30 MPH channel only restriction, adds exclusionary language for shoreline to shoreline zones and splits zone descriptions into multiple paragraphs for clarity. The amendment also updates the rule maps and removes the responsibility of Pinellas County and the City of Clearwater to mark the zones.
