The City of Sunny Isles Beach commission on Nov. 20 received an update on efforts to maintain a 20 mph speed limit on internal streets and on accompanying traffic-calming measures.

Commissioner Joseph asked for a status report on the proposal to keep internal streets at 20 mph and on county-proposed traffic-calming options. A city staff member told the commission that the Miami-Dade County Commission will place a resolution on its agenda "to pave the way" for Sunny Isles Beach to pursue the 20 mph reduction; staff said any county approval would include criteria and that the city would still need to complete and submit a traffic study for final sign-off.

Staff also said the city contracted a consultant (referred to in the meeting as Caltrans) to prepare civil design work and traffic studies, including designs tied to a separate agenda item for the 100th and 83rd Street left-turn. The consultant’s preliminary plans include a two-way bike lane; staff warned the lane would require substantial curb relocation and the loss of many trees, and suggested presenting trade-offs to the commission in January.

On paint and visibility, a commissioner noted that the bike lane markings on Collins Avenue can be hard to see in bright sun and asked whether the city could request green paint for bike lanes. Staff cautioned that the state has strict regulations on lane striping for shared lanes and said the city would ask the state but did not expect approval for green paint in a shared-lane context.

Staff described other traffic-calming options under consideration, such as speed humps and narrowed intersections, and said enforcement and further design work will continue before the commission considers formal code changes or striping plans.

The commission did not take any formal action at the workshop; staff said it will return with design presentations and recommended trade-offs in January.
