Research notes
Hawaii's federally-approved CZM program. SMA boundaries are mapped by each county and typically extend inland from the shoreline; encompass large portions of habitable coastal Oahu, Maui, Kauai, Hawaii. Counties administer permitting under state CZM consistency standards. Federal conflict check enabled — interplay with NOAA CZMA, USACE §404, ESA marine species, and federal flood insurance program (NFIP).
