Coastal Buffer Section

Sectional strategy for the coastal buffer showing retreat, coastal park interventions, dune formation, and public promenade access tied to heritage nodes along the shoreline.

Key moves

• Managed retreat: Adapt or relocate residences behind the coastal promenade class B line; move commercial uses inland.
• Coastal park: New public green space replaces vulnerable frontage, absorbing storm surge with cut-and-fill grading.
• Dune and vegetated buffer: A restored dune system and native coastal planting protect the inland edge.
• Promenade: Front Street reprogrammed as a pedestrian-priority coastal walkway connecting heritage sites.

The section also shows the mauka-to-makai relationship and the ahupua’a system logic at the regional scale.
