A new map shows 1,800 buildings in Portland that could be in trouble if an earthquake hits.

The City of Portland released a map and database of unreinforced masonry buildings that could be vulnerable from shaking during an earthquake if they aren't structurally retrofitted.

The map shows locations throughout the city, with large clusters in the downtown and inner southeast areas.

The city reports that unreinforced masonry buildings – also known as URMs – were generally constructed before the 1960s using brick and little to no steel reinforcement in the walls.

Since the last time Portland collected similar data in the 1990s, only 13 percent of the approximately 1,800 URM buildings have been fully or partially upgraded. Another 8 percent were demolished.

The new building data was collected as part of the Portland URM Seismic Retrofit Project, which is working on a mandatory URM retrofit policy, along with incentives for building owners. The Portland City Council will consider those proposals later this year and the public will be given an opportunity to comment on the proposed policies.

City leaders report that other cities on the West Coast, including San Francisco and Los Angeles, already have similar policies in place.

The Portland Bureau of Development Services, Portland Bureau of Emergency Management, Portland Development Commission and community members have been involved in the project.
