Eugene -Springfield Area Natural Hazards Mitigation Plan 4. Risk and Vulnerability The following is the recommendation submitted to the State on April 1, 2017: The conclusions of this report identify the Eugene and Springfield's minimum number of bridges needed to be operational after the Cascadia Seismic Event. Methodology Eugene and Springfield have identified detour routes around most bridge structures on their critical response routes. Detour routes are not presented in this report. This report addresses only the critical route bridges lacking realistic detour routes. Several assumptions set the context of this memo: 1) ODOT has determined that HELP will come from Eastern Oregon via HWY 58; 2) Overcrossings over I-5 that may collapse onto I-5 will be driven around or pushed out of the way; 3) Beltline Interchange at I-5 is anticipated to be operational directly after the seismic event; 4) Riverbend Peace Health and McKenzie- Willamette Hospital will be operational and the triage point for mass casualties; 5) The Eugene Airport will be a critical lifeline for transportation, response personnel and equipment, medical personnel, pharmaceuticals, and water purification needed almost immediately (and long into the recovery effort) after the event; 6) There will be no help from Salem or Portland because they will be caught in the same event; yet Eugene -Springfield will be the gathering point for refugees from the coast and the south. 7) Eugene Springfield have a combined Fire and EMS department needing access across the Eugene, Springfield, and surrounding area. Conclusion Bridges that must be Operational after the Event 1) 08638: Beltline over Willamette River— Sufficiency rating— 74. Cost to upgrade = $2, 000, 000. 2) 08705: Debrick Slough WB On Ramp to Beltline— Suff[Sufficiency] rating = 64. Cost to upgrade = $450, 000. The following three bridges are critically needed to bring HELP from I-51HWY 58 to the southern end of Springfield and Eugene. The Glenwood area is planned to be a freight off-load and redistribution point. 1) 016329: Glenwood Blvd over UPRR [Union Pacific Railroad] — Suff[Sufficiency] rating = 93. Cost to upgrade = $300, 000. 2) W6099C: Franklin Blvd over HWY 1 W and UPRR [Union Pacific Railroad] — Suff [Sufficiency] rating = 55. Cost to upgrade =$2, 000, 000. 3) 08051: Main Street over Willamette River (Springfield) - Suff[Sufficiency] rating = 4-22 January 2020
