HI HB1465

Extends minimum shoreline setback from 20 feet to 40 feet inland from the shoreline, with counties required to add additional distance based on average annual erosion rates over a 100-year projection period.

Requires affected agencies and counties to account for sea-level rise and minimize risks from coastal hazards including tsunamis, hurricanes, wind, storm waves, flooding, erosion, and subsidence in development planning and review.

Mandates that development in special management areas not impede public access to shorelines and beaches, and requires adequate public access provisions by dedication or other means.

Expands the definition of coastal hazards in the coastal zone management law to explicitly include hurricanes, wind, sea-level rise, and wave damage alongside existing hazards like tsunami and erosion.

Increases variance approval threshold for erosion protection structures from $20,000 to $50,000 and adds new variance category for temporary emergency protection of legally inhabited dwellings at risk from shoreline erosion or coastal hazards.
