This report is a preliminary assessment of potentially unreinforced masonry buildings (URMs) in Nevada. URMs are highly susceptible to collapse or partial collapse during earthquakes and are therefore of concern for life safety and economic recovery. Data are compiled from information provided by county assessors’ offices and the Public Works Division of the State of Nevada with assumptions that potential URMs are those brick, stone, or cement-block masonry buildings that were constructed before 1974. There are tens of thousands of potential URMs in Nevada. They are located in every county and nearly every community. Many URMs are historically significant, and many are concentrated in downtown business districts and along thoroughfares. It is important to note that not all Nevada URMs have been identified in this study, and some structures identified as potential URMs may not be. Risks from URMs can be reduced by removing the buildings, seismic rehabilitating them, and minimizing human occupancy.
Major recommendations include the following:
(1) Jurisdictions (cities, counties, the State of Nevada, tribes, and the federal government) should follow up with on-the-ground inspections and checks of building plans. Individuals should determine if their buildings are URMs.
(2) Jurisdictions should work toward seismically rehabilitating URMs or removing them from human occupancy.
