I wonder why a business would want to rent flooded land, in a floodplain, and possibly a wetland as well. Perhaps Mapunapuna could be the poster-person, for innovation, which is an early response to sea level rise. Surely innovation is not mere reductions in rents or leases? Would not innovation be a physical project to actually prevent this flooding? Holland has done it, we will need to be doing it. Mapunapuna is a great place to start because the area is confined, not impacted by irregular ocean wave patterns, and is not nearly as valuable as, say, Waikiki. Why not  build walls around Mapunpuna to keep water out, add some solar powered pumps to pump out any water which creeps in, and construct modest bridges from Nimitz and possibly other streets to cross the flood walls? Rents might actually be increased in such a scenario. Downing is right on the money, by a mere lowering of rents, the risks to public health and safety will increase and not abide. Please, think big and long term.
