ALTERNATIVE 1 – MAXIMIZE REDEVELOPMENT RISK REDUCTION

 The following set of slides depicts the potential flood risk reduction along a profile of Merchant’s Way and Main Street for Alternative 1.

 The colored bands correspond to the annual risk of inundation during coastal storm events. For example, as early as 2030, there is an estimated 50% chance that water will rise to the low point on Merchant’s during a coastal storm at least in any given year.

 The following three images show that the colored bands rise vertically on the profile, indicating that flood risk on Merchant’s Way and Main Street increases over time. The proposed alternative provides moderate risk reduction in the short term and becomes less effective over time.

 This table indicates the risk reduction in any given year provided by elevating and/or dry floodproofing redeveloped buildings and a vegetated berm compared to the existing conditions at the highest and lowest points on Merchant’s Way.
