We cannot predict earthquakes, but we can predict how a building performs in an earthquake. Seattle has 1,100 unreinforced masonry (URM) buildings that are vulnerable to collapse in an earthquake because they lack structural reinforcements. SDCI is supporting efforts to seismically retrofit these buildings. SDCI is coordinating with first responders… [ Keep reading ]
For the fourth year in a row, the White House declared May to be Building Safety Month. Building Safety Month highlights the importance of building codes to protect our homes, businesses, and roads against earthquakes, floods, and extreme weather. Seattle’s Building Safety Month proclamation commits to retrofitting Unreinforced Masonry (URM)… [ Keep reading ]
The City of Seattle is holding a listening session for developers and owners of URM buildings for a proposed new Transfer of Development Rights (TDR) program to support seismic retrofits of URM buildings. The Seattle Department of Construction and Inspections (SDCI) and Office of Planning and Community Development (OPCD) are hosting this meeting on Tuesday, February 27 from 1:30 – 3:30 p.m. in the Bertha Knight Landes Room in Seattle City Hall. You can register and view the meeting agenda for this in-person event on the Unreinforced Masonry Buildings website.
Reflecting on seismic activity in 2023, nine deadly and damaging earthquakes occurred globally. In February, Turkey and Syria experienced two earthquakes over magnitude 7.5 that killed over 59 thousand people. In September, Morocco experienced a magnitude 6.8 earthquake that killed almost three thousand people. In October, Afghanistan experienced a magnitude 6.3 earthquake that killed over one thousand people. In November, Nepal experienced a magnitude 5.7 earthquake that killed over 150 people. In December, China experienced a magnitude 5.9 earthquake that killed 149 people. Four additional earthquakes in Afghanistan, Ecuador, Turkey, and the Philippines each resulted in deaths of ten or more people. While earthquakes cannot be predicted, we know Seattle will experience a damaging earthquake in the future and we can predict how buildings will perform in an earthquake. 2023 was a year of progress and milestones in advancing the seismic resilience of Seattle’s unreinforced masonry (URM) buildings, buildings that are prone to collapse in an earthquake.
SDCI is celebrating a major milestone on the pathway to improving Seattle’s earthquake safety. On September 26, 2023, the Public Safety and Human Services Committee voted 5-0 to refer Resolution 32111 to a Council vote. This resolution supports the development of a voluntary seismic retrofit ordinance that will establish a minimum seismic safety standard for the retrofit of unreinforced masonry (URM) buildings. URM buildings are classic red brick buildings, generally constructed before 1945, and are prone to collapse in an earthquake. Seattle has 1,100 URM buildings and an 86% chance of experiencing a damaging earthquake in the next 50 years. Adopting a mandatory URM retrofit ordinance continues to be the City’s long-term goal. However, adding a short-term goal to adopt a voluntary URM retrofit ordinance provides assurance to URM building owners that by retrofitting to the established standard, they will be compliant with future mandatory requirements. Resolution 32111 is scheduled for a vote by full Council on October 10.
