The Nature Conservancy and Environmental Law Institute Duck-Pensaukee Watershed Approach Pilot Project (TNC-ELI DPWAP) Wetland Preservation Tool:1 The planning team considered opportunities for wetland preservation to consist of both existing wetlands in the Duck-Pensaukee watershed as well as areas along the Lake Michigan coast that alternate between upland and wetland conditions. Opportunities for wetland preservation, which were indicated by the extent of existing wetlands in addition to unmapped potential wetlands along the coast (see table below), were integrated into the Wildlife Tool, Flood Abatement Tool, Surface Water Supply Tool, Water Quality Protection Tool, Carbon Storage Tool, Shoreline Protection Tool, and Fish Habitat Tool.

Factor used in analysis

Data source(s)

Current wetlands

Kramer et al. (2012) Jurisdiction Tool:2 Prioritizes potential sites that are less vulnerable to development because they are within the Savannah Corps District's definition of jurisdiction for wetlands ("within 100 feet of navigable waters or within the 100 year floodplain") under §404 of the Clean Water Act. Kramer et al. (2012) used the output from this tool as input for the Potential Wetland Banking Site Index. Factors and associated data sources underlying this tool are provided below:
