If you live on an island, and your groundwater table is tidal, what should your datum be for storm water planning purposes? Average tide? High tide? Seasonal high tide? If you are the local official with this problem, what do you do, realizing that the difference from mean tide and seasonal high tide (when most flooding occurs) is 1.5 feet? Realizing that property and infrastructure is at much higher risk for periodic inundation, does the failure to address the problem indicate a lack of willingness, understanding, hope or leadership? We see all four responses among local officials, but the “head in the sand” mode is the most curious. It’s tough challenges that often define leaders. With sea level rise, there is time to plan, construct infrastructure in stages, arrange funding, and lengthen the life of infrastructure and property. Meanwhile, those insurers, banks and the public we talked about in a prior blog wait and watch.
