Portland District People - Natalie Ehrlich
Natalie Ehrlich, District geotechnical engineer, enjoys sleuthing when doing dam risk assessments. "It gives me a chance to really get to know our dams, digging through old construction photos, design documents, and exploration logs," she said. "(This) involves evaluating the seismic risk to our existing rockfill embankment dams. The original dam designers did not know about the high seismic risk we live under in the Pacific Northwest, and I help to evaluate and mitigate that risk."
