Active and Recently Completed Projects
- Primary contact for DOGAMI’s flood mapping and base flood elevation determination services.
- Vulnerability and risk assessments to produce loss estimations and population exposure to various natural hazards, including flood, earthquake, landslide, tsunami, coastal erosion, and wildfire. Work is ongoing in Tillamook, Lincoln, and Curry counties. Role: Project lead. Period: 2014 to present.
- Assessment of channel migration susceptibility for large streams in Oregon to establish a statewide screening resource to be used for prioritizing future channel migration mapping efforts. Role: Project lead. Period: 2014 to 2015.
- Compilation of the Oregon Statewide Flood Hazard Database, which includes flood study data, high water marks, and observed flood inundation zones. Role: Project lead. Period: 2013 to 2015.
- Revision of Flood Insurance Rate Maps (FIRMs) and development of maps and web tools for understanding exposure to flood hazard in Curry, Harney, Coos, Multnomah, Clackamas, Clatsop, Tillamook, and Lincoln counties. Funded through FEMA's Map Modernization and RiskMAP programs. Role: Technical lead. Period: 2008 to 2015.
- Modeling and mapping of tsunami inundation for Oregon's coastline. Funded through NOAA's National Tsunami Hazards Mitigation Program. Role: GIS support and cartography. Period: 2009 to 2013.
- Mapping exposure of buildings and infrastructure to Mount Hood's volcanic hazards. Funded through the USGS's Cascades Volcanic Observatory. Role: Hazard modeling, GIS support, and cartography. Period: 2009 to 2011.
- Miscellaneous lidar-based mapping projects, including the Lidar Imagery Series. Role: Cartographic design.
