The built environment consists of elements humans have constructed: the buildings in which we live and work, the roads upon which we drive, the utility infrastructure that delivers power and water, and even the policies which govern where and how we build can all be considered part of the built environment. When wildfire impacts the built environment, the consequences can be significant. Many of the most destructive and deadly fires in the U.S. far exceed what even the best suppression or mitigation in the natural environment can achieve. It is only through preparation in the built environment that communities can withstand those fire events. The Commission made a number of related recommendations focused on community mitigation and structure hardening (R1-R6), utility infrastructure (R7-R9), water supplies (R34-R39) as well as recommendations related to public health protections in the built environment (R43-R44).
