According to NOAA (2018), the U.S. spent a record $306 billion on weather and climate disasters in 2017, up nearly $100 billion from the previous record in 2005 following Hurricane Katrina. From unprecedented rainfall and flooding from Hurricane Harvey in Houston, Texas, to ravaging wildfires and devastating mudslides near Santa Barbara, California, cities across the U.S. are grappling with how to better prepare for and recover from catastrophic natural disasters. These events bring into focus the need to prepare for similarly unprecedented events in Portland.

The Resilient Infrastructure Planning Exercise (RIPE) began in early 2017 as an effort to better understand the risks posed by major natural disasters to the City of Portland’s (City) infrastructure, and to identify near- and long-term steps to build the resilience of those systems.

RIPE was specifically focused on the intermediate and long-term recovery phase of a disaster, rather than emergency response (see Figure 1). The Federal Emergency Management Agency (FEMA) describes the recovery process as a sequence of interdependent and often concurrent activities that progressively advance a community toward a successful recovery. Steps taken by Portland to build resilience (e.g., mitigation and preparation), and to have clearly established recovery priorities in place prior to a disaster, will have positive cascading effects resulting in a faster and more successful recovery.


Resilient Infrastructure Planning Exercise (RIPE) was funded by the Global Consortium for Sustainable Outcomes (GCSO) through its CapaCities Project, a collaboration between five international cityuniversity pairs exploring the role of universities in supporting implementation capacity of city-led sustainability efforts.
