HI SB830

Amends the definition of "development" under Hawaii's coastal zone management law (Section 205A-22) to exclude reconstruction of lawfully constructed structures that are substantively similar to their original footprint or dimensions.

Applies the reconstruction exemption only when structures were damaged or destroyed in a governor- or mayor-proclaimed state of emergency and federal disaster declaration, excluding disasters related to waves, storm surge, high tides, flooding, erosion, sea level rise, or subsidence.

Adds new exclusions from the definition of "development" including Hawaiian traditional and customary practices near traditional Hawaiian fishponds (loko i'a).

Maintains existing provision that excluded uses may still be classified as "development" if the authority finds they have cumulative impacts or significant environmental or ecological effects on special management areas.

Takes effect July 1, 2025.
