Preliminary Virtual Reconnaissance Report (PVRR)

The first product of StEER’s effort to learn from the Nashville Tornadoes of 3 March 2020 is this Preliminary Virtual Reconnaissance Report (PVRR), which is intended to: (1) provide an overview of the tornado sequence, particularly relating to the impact of strong winds and wind-borne debris on the built environment, (2) overview the regulatory environment and construction practices in the affected area, (3) summarize the preliminary reports of damage to residential and commercial construction, as well as critical facilities such as schools, airports and power infrastructure, (4) establish current conditions in the affected area with respect to access and services, (5) outline recommendations to inform the continued study of this event by the engineering reconnaissance community, including interdisciplinary teams focusing on sheltering choices and decision making. As the product of entirely virtual reconnaissance, the PVRR is not based upon detailed field investigations by StEER.
