1. TO Dp COAST DAMAGE ASSESSMENT EXTENSION As more cities and regions are hit hard by storms public pressure for better infrastructure planning is growing A consensus is emerging that in many cases putting it back the way it was is not the right answer Community leaders may be ready to take new actions to adapt to changing conditions but may also be unsure whether such new ideas are good investments They may well ask How much should we pay to lower risks and where is the line between a wise choice and a foolish one Coastal Adaptation to Sea Level Rise COAST is a tool that helps communities answer these questions It predicts damages from varying numbers of storms of different intensities and evaluates relative benefits and costs of response strategies that stakeholders select The COAST process uses two types of information to help communities evaluate their options when planning their response to these changing conditions The first is a map that contains a graphical representation of the damages caused by a specific storm scenario This map is useful to help people visualize the areas that will be flooded and the monetary effects of that flooding Each group of stakeholders can use different criteria to define damages in the context of their local population For example they might want to look at lost tax revenue or the costs for businesses that may have to close or relocate The
