Eugene -Springfield Area Natural Hazards Mitigation Plan 4. Risk and Vulnerability The highest risk areas identified were the south hills of Eugene and southeast hills of Springfield. The report identified existing structures located on deep landslides as the primary landslide hazard in the study area. Report recommendations included: Increased public outreach for property owners to heighten awareness of the hazard and precautions needed, through mitigation, to reduce the risk posed by landslides; • Incorporate landslide hazard maps and risk reduction strategies into community planning efforts; and Create a landslide emergency response plan to better prepare and react to a landslide occurrence. Over the course of the next five years Emergency Management and Planning staff will analyze the study to determine areas and buildings at risk from landslides and propose comprehensive land use policies and construction standards accordingly. 4.7.4 Lifelines and Critical Bridge Evaluations In 2017 the Oregon Department of Transportation (ODOT) has asked Lane County to complete these two tasks: 1. Review locations of seismically vulnerable bridges along the ODOT lifelines and identify alternate routes that can be used if an earthquake occurs before the necessary bridge work is completed. Assess the feasibility, seismic vulnerability and corrective cost of these alternate routes. 2. Identify local lifelines and assess corrective costs of any vulnerable bridges. Prioritize the replacement/rehab work to remove seismic vulnerabilities in a reasonable timeline. There will be priorities placed on bridges along these routes needing retrofitting or replacement. Some of these bridges can be avoided using alternate routes, saving money for other bridges that cannot be avoided. (See the Lane County Bridge Resiliency in the Event of an Earthquake Study, by the Engineering and Construction Services Division 41112017) The Cities of Eugene and Springfield understand the main ODOT routes in our area are Hwy 58 to I-5; which will be critical lifelines during a Cascadia event. However, just as critical will be the need to get equipment, personnel, and supplies from these routes to the City's internal transportation routes, supplying our Points of Distribution and Staging Areas. To this end we selected the bridges for upgrades to the ODOT routes. The Cities of Eugene and Springfield can support each other in many ways, but without these critical lifeline bridges we are virtually cut off from one another. The most glaring example is the only two major hospitals that support the area reside in the City of Springfield. This alone will put more than 165,000 people without access to a major medical facility. 4-21 January 2020
