A RESOLUTION AMENDING THE CITY OF EUGENE ANNEX TO THE
LANE COUNTY MULTI-JURISDICTIONAL NATURAL HAZARDS
MITIGATION PLAN ADOPTED BY RESOLUTION NO. 5446.
The City Council of the City of Eugene finds that:
A. On May 12, 2025, the Eugene City Council adopted the City of Eugene Annex to
the Lane County Multi-Jurisdictional Natural Hazards Mitigation Plan ("Eugene NHMP") which,
in its Section 4.05, includes 24 mitigation action items identified as Mitigation Action Items (A)
through (X).
B. The Federal Emergency Management Agency ("FEMA") provides guidance for the
adoption of local natural hazards mitigation plans and Appendix D of the FEMA Local Mitigation
Planning Policy Guide supports the City's addition of mitigation action items to the Eugene NHMP
between regular plan updates.
C. The 5-year Capital Program adopted by the Eugene-Springfield Metropolitan
Wastewater Management Commission ("MWMC") includes a seismic retrofit of the Owosso
Bridge, a bicycle/pedestrian bridge that carries an MWMC wastewater forcemain across the
Willamette River in Eugene.
D. The Eugene NHMP identifies the need for seismic upgrades to facilities and
infrastructure and should be amended to include the Owosso Bridge seismic retrofit as a mitigation
action item to facilitate MWMC's application for grant funding for the project.
NOW, THEREFORE,
BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF EUGENE, a
Municipal Corporation of the State of Oregon, as follows:
Section 1. The City of Eugene Annex to the Lane County Multi-Jurisdictional Natural
Hazards Mitigation Plan is amended by revising the paragraph under Section 4.05 that follows the
heading "2024-2028 Mitigation Action Item Summary" and that precedes Table 4.7.12 so that the
paragraph now provides:
The following provides a summary of the selected 2024 -2028 mitigation action items. The
COE MJNHMP supporting departments -Emergency Management, Facilities, Public Works
(6 divisions), Eugene Springfield Fire and Planning -worked individually and as a group to
select and make final edits to the Mitigation Action Items identified as (A) through (X), below
with initial review initiated on 05/09/24 and final review on 06/21/24. Mitigation action items
added to the COE MJNHMP after its May 2025 adoption are not included in the data captured
in Table 4.7.12.

Section 2. Section 4.05 of the City of Eugene Annex to the Lane County Multi-
Jurisdictional Natural Hazards Mitigation Plan is amended by adding, after Mitigation Action Item
(X), the Owosso Bridge seismic retrofit project as "Mitigation Action Item (Y)" as shown in
Attachment A to this Resolution .
Section 3. The City Recorder, at the request of or with the consent of the City Attorney ,
is authorized to administratively correct any reference errors contained in this Resolution.
Section 4 . Thi s Resolution is effect iv e immediate ly upon its p assage by the City Council.

Attachment A
• Seismically retrofit the Owosso Bridge , a 490-foot-long off-
street path bridge which carries MWMC's 54-inch wastewater
forcemain across the Willamette River. The bridge is owned by
MWMC and was constructed in 1982. Engineering and
seismic evaluations identified multiple critical seismic
deficiencies, including inadequate girder-to-pier connections,
understrength shear keys, deficient abutment and pier H-
piles, unconfined pier walls, and insufficient bracing of the
54-inch pipeline. Girder separation during a major earthquake
would likely damage the forcemain, causing a major
wastewater release and long-duration service disruption.
• The retrofit includes both Phase I and Phase II measures
which are recommended to achieve the desired performance
level: girder closure strengthening, shear key extensions ,
lateral pipeline bracing, abutment vault bracing, concrete
footing overlays, addition of steel pipe piles at abutments and
piers, pier wall steel jackets, and foundation extensions.
These improvements create reliable earthquake-resisting
systems (ERS) and earthquake-resisting elements (ERE) to
ensure that the bridge and pipeline maintain serviceability
during a Cascadia Subduction Zone earthquake.
• This action was identified in the MWMC Disaster Mitigation
and Recovery Plan (March 2020) and is required to protect
regional wastewater lifeline functionality serving Eugene and
Springfield.
