Floodplain Ecosystem Service mapper

This web mapping application helps users assess, quantify, and value the ecosystem services provided by floodplains in the Delaware River and Chesapeake Bay watersheds. It displays field site data, LIDAR mapping, and geomorphic modeling used to demonstrate sediment and nutrient soil retention in the watersheds, including the following datasets:

• Field site data for 68 sites in the Chesapeake and Delaware Floodplain Network, including site photos;
• Stream reach estimates of channel geometry derived using the Floodplain and Channel Evaluation Tool (FACET) and LIDAR-derived digital elevation models; and
• The active (field verified two-year) floodplain extent derived from FACET.

Users can toggle between various basemaps, map layers, and geographic features within a floodplain, or download both the underlying data and the FACET software.
