Table 4. Cost/ benefit of IPCC sea level rise scenarios at the study area, considering ecosystem services provided by publicly owned (low marsh and open water) vs. privately owned properties (salt flat, high marsh, uplands). The upper portion vs. lower portions of the table compare two different rates of return on private property investment during the modeled period, 3% vs. 6%. Gains are in bold. Units are in US Dollars (2006) per year, i.e., $/yr.
