DUNEDIN — City commissioners have directed staff to draft an ordinance banning the launch of jet skis and other motorized watercraft from the Dunedin Causeway, where an ongoing closure for storm repairs has spurred a resurgence of seagrass and native wildlife. Commissioners reached consensus at a June 2 work session, asking staff to work with the city attorney on the ordinance. Adopting it would still require two public hearings, City Manager Jennifer Bramley said.
