Abstract
Using the model of biological potential along urban1 land cover gradients in North Carolina constructed
using EPT and biotic index metrics, a web application (ArcGIS StoryMap) was constructed to visualize the
results for every urban (>1% impervious cover) watershed in North Carolina. The web application allows
any user to identify the potential EPT richness and NCBI score for any watershed constrained by
urbanization. This constrained biological potential is provided as both a scaled value (comparable across
the state) and ecoregion specific actual predicted score. Watershed managers should be able to use this
information to help guide urban stream prioritization, planning, restoration and monitoring and the
concept would support construction of a tiered aquatic life use framework. NCDEQ agreed to host the
web application as part of the ArcGIS StoryMap service and the plan is to migrate the web application to
the state for this purpose.
