Key point here is that the State is responsible for the upkeep.  That means any injuries resulting from the sea walls condition is the State's kukeana.  Big liability issue here and any litigation would dwarf the amount needed for repair!  Hope Doug Chin is "penny wise and pound foolish".

Served on a jury where someone sued the City over a severely uneven sidewalk.  Ruled in favor of the City as, we the jury deemed that the City could not know about the defect due to the vastness of City sidewalks.  This was explained to us by the judge as a legal consideration during the hearing.  In the case of the sea wall, the State knows it is in disrepair and there are areas of damage and concern.  Don't see how the State escapes liability if someone is injured due to the condition of the sea wall.
