Eugene -Springfield Area Natural Hazards Mitigation Plan 1. Mitigation Planning around the cities and levies has contributed to flood mitigation as demonstrated in the 2019 Spring flooding. Formal planning between the two cities, working as partners, to address natural hazard planning began in 2009. The following sections (Section 1.1 — 1.5.2) provide a high-level overview of historical planning efforts, who was involved in the completion of the 2020 NHMP, the conclusions reached through the plan development, and the cities vital steps forward. 1.4.1 How was the 2020 NHMP Developed? Previous planning and new information guided the 2020 NHMP mitigation actions items. hi 2009, Eugene and Springfield and partner agencies developed the 2009 NHMP for the most significant natural hazards for our area. In 2013, Eugene and Springfield, with support from the Oregon Partnership for Disaster Resilience, conducted a 2014 Regional Climate and Hazards Vulnerability Assessment,3 or the 2014 Vulnerability Assessment for short. In 2014, Eugene and Springfield and partner agencies developed the 2014 NHMP for the most significant natural hazards for our area. This plan was based on many of the findings from the previous 2009 NHMP and the 2014 Vulnerability Assessment. In 2016 and 2017, the Cities of Eugene and Springfield conducted seismic evaluations of their critical infrastructure. The Oregon Department of Transportation (ODOT) also completed seismic evaluations of priority bridges,¢ and the Oregon Department of Geology and Mineral Industries (DOGAMI) completed an extensive landslide hazard and risk study in central Lane County. The Eugene Water and Electric Board (EWEB) and Springfield Utility Board (SUB) are both long time participants in the Eugene -Springfield Area Multi - Jurisdictional NHMP.
