Funding Culvert Replacement: Leveraging FEMA to Support Salmon, Property, and Public Safety| 2020

The built environment can significantly impact ecosystem services, especially where infrastructure is designed without full consideration of stream ecology and aquatic migratory species. By expanding our understanding of the value of improved stream crossings to include not only ecological costs, but also conventional risks (e.g., localized flooding, transportation disruptions), we can build a modernized transportation infrastructure that supports both human needs and larger ecological and hydrological processes. Our team has developed innovative, scalable geospatial techniques for identifying conventional risks associated with blocked and degraded stream crossings that can be applied to watersheds and regional basins where recent, high-quality geospatial data are available.
