Traffic study, bridge and dredging central to Marina Island plan; residents press for bayou restoration and marine protections

City planners and Marina Island representatives told a Lynn Haven workshop that an in-depth traffic study has been completed and recommended infrastructure changes to support the project, while residents urged environmental restoration of the bayou.

Amanda, a city planner, said an “in-depth traffic study was completed” and will be available at the public hearing, and that staff had directed the consultant to analyze specific roads and intersections. The study, as described at the workshop, examined both Phase 1 and full build-out. It found Phase 1 roadways would operate adequately but projected adverse impacts on several segments at full build-out, including North Shore Road (State Road 390 to Goose Bayou Road) and West Ninth, Tenth and Twelfth streets.

The study recommendations described at the workshop included building Marina Island Boulevard as a divided two-lane facility with right-turn lanes, a roundabout or alternative traffic control at Marina Island Boulevard and Tennessee Avenue, and signalization or alternative control at Marina Island Boulevard and State Road 390. The developer representative said Marina Island Boulevard is intended to be constructed early in the project and that the team plans to bring the road and rails-to-trails connections into the city network.

Residents used the public comment period to press for environmental work. Multiple speakers described accumulated sediment and damaged seagrass in the bayou and asked who will dredge and maintain the channel in the future. A Marina Island representative said the team will dredge the channel to the bridge at Arthur Drive as part of the marina application and that the developer has committed roughly $6,000,000 for the bridge and dredging work. The developer also said dredging and a larger cut will improve flushing and that the Corps and state environmental regulations will govern marine work.

The nut graf: Traffic and marine engineering are tied to permitting — the traffic study will inform intersection designs and phasing decisions, while the dredging/canal cut and marina permits will require Corps and state approval and environmental mitigation. Developers said the marina and bridge work will be submitted early in the development-order sequence; staff said subsequent development orders will require separate traffic analyses for later phases.

Ending: Commissioners and staff said city review at the development-order stage will provide additional opportunities for technical comment and community feedback on traffic, stormwater and marine environmental protections.
