How to report a landslide
Some parts of Portland are prone to landslides, especially in the West Hills and higher elevations on the east side. Rain, loose fill, groundwater under streets, and other factors can push water, mud, and debris onto city streets and damage private property.
If you live in an area known to experience landslides, be alert – particularly during periods of heavy rain or snowmelt – and keep ditches, culverts, and trash racks clear of debris that could impact stormwater runoff.

What to Expect for Property Owners
Once notified, a City inspector will assess the landslide and its impact to structures in the area. Due to safety considerations, inspections will be limited to daylight hours. In most cases, property owners will need to hire a geotechnical and/or structural engineer to provide a report to BDS on the landslide and any repairs needed.
