Service Description: This vector (polygon) database contains predicted sea level rise extent layers and baseline layers for the coastal New Hampshire, including the open coast, the Piscataqua River, and Great Bay. Data are based on 2019/2020 LiDAR data and comprise eleven scenarios. The scenarios combine Mean Higher High Water, 100-year flood predictions, and 2ft increments of sea level rise.
