MEMORANDUM
FROM: Mark Metzger, Planner
SUBJECT: WILLAMETTE GREENWAY OVERLAY DISTRICT DEVELOPMENT (WG) &
DISCRETIONARY USE (DU) APPLICATION; SITE PLAN REVIEW—I‐5
WILLAMETTE RIVER BRIDGE PROJECT PHASE II
ISSUE: A public hearing before the Planning Commission is scheduled for December 1st to consider a
Willamette Greenway Overlay District Discretionary Use application and a related Site Plan Review
application for Phase II of the Willamette River I‐5 Bridge project.
Phase II involves the following activities within Springfield’s planning jurisdiction:
Bicycle/pedestrian path improvements within the Eastgate Woodlands area owned by
Willamalane Park and Recreation District.
Landscaping, re‐vegetation, restoration, and mitigation
Stormwater treatment facilities receiving runoff from bridge related facilities.
DISCUSSION: The focus of the Willamette Greenway Discretionary Use permit is on the impacts of the
activity on the riparian area along the Willamette River. These impacts include both environmental and
aesthetic impacts. At the December 1st hearing, the Commission will be asked to review staff findings
with respect to anticipated impacts that will occur during Phase II.
The application packet is quite voluminous. Staff has included key excerpts and drawings that address
the decision criteria for the proposed land use actions in the attached staff report. A copy of the full
text of the application and drawings are available for Planning Commission review upon request.
RECOMMENDATION: The proposed development within Springfield’s jurisdiction is minimal and few
comments were received from Public Works, Transportation and Fire and Life Safety. It is the opinion of
staff that sufficient findings have been presented to support a recommendation that the Planning
Commission approve the proposed Willamette Greenway Discretionary Use application (SHR2009‐
00003) and Site Plan Review Application (DRC2009‐00040), as conditioned by the recommendations of
staff.
ACTION REQUESTED: The Planning Commission is requested to approve, approve with conditions or to
deny the proposed Willamette Greenway Discretionary Use application (SHR2009‐00003) and Site Plan
Review Application (DRC2009‐00040) for the Willamette I‐5 Bridge Replacement project.

I. Executive Summary
On February 18, 2009, the Planning Commission granted approvals for Willamette Greenway Overlay
District Development and Discretionary Use permits for Phase I of ODOT’s Willamette River I‐5 Bridge
Replacement project in Glenwood. Phase I involved: development of temporary construction staging
areas and access routes; construction of temporary work bridges; demolition of the existing Willamette
River Bridge; construction of new bridge sub‐structure; and temporary and permanent bicycle and
pedestrian path improvements. Phase I is under way.
This proposal is for Phase II of the project which includes construction of the replacement bridges within
ODOT right‐of‐way, and related work outside the right‐of‐way. The focus of the Planning Commission’s
evaluation will be on those activities and development that will occur outside of the ODOT right‐of‐way
where the city has planning and regulatory jurisdiction. These activities include landscaping, re‐
vegetation, restoration and mitigation; permanent bicycle/pedestrian path improvements; and
stormwater management facilities serving the bridge facility.
The Phase II work described in this application is planned commence in 2010 will continue through
December 2012. Construction of the new facilities will require three more summers of in‐water work,
which is only allowed from June 1 to October 31.
The focus of the Willamette Greenway Discretionary Use permit is on the impacts of the Phase II
activities on the riparian area along the Willamette River. These impacts include both environmental
Attachment 1-1
and aesthetic impacts. At the December 1st hearing, the Commission will be asked to review staff
findings with respect to anticipated impacts that will occur during Phase II.
Based on a review of the Applicant’s proposal, staff has made many findings which support a
conclusion that the Applicant has generally satisfied the review criteria for a Willamette Greenway
Discretionary Use Permit found in SDC Section 3.3‐325 and 5.9‐120.
SDC Section 5.9‐115 states that “typically a Discretionary Use application is reviewed concurrently with a
Site Plan Review application. As such, this staff report includes findings which support a conclusion that
the Applicant’s proposal has generally satisfied the review criteria for Site Plan Review found in Section
5.17‐125.
The impact of Phase I and Phase II construction activities are largely the same. Much of the
environmental review that was prepared by ODOT for Phase I included the impacts of Phase II. For this
reason, many of the findings included in this report repeat those included in the staff report provided to
you for Phase I.

Attachment 1-2
The Oregon Department of Transportation (ODOT) (“the Applicant”) requests approval to commence
Phase II construction of two new bridges that will carry traffic in one direction each, northbound (NB)
and southbound (SB).
The new bridges will be constructed in essentially the same location as the existing bridges; including
relatively minor shifts of alignment, as well as minor changes to the Franklin Boulevard ramps. The new
bridges will be designed with enough width to eventually carry up to six lanes of traffic (three in each
direction) to meet the projected traffic needs for the next 20 years. However, upon project completion,
the new bridges will be striped to carry two lanes in each direction, matching the current I‐5
configuration in this area.
Since the project overlaps both Eugene and Springfield jurisdictions, both cities will hold similar reviews
of the project. Demonstration of compliance with applicable land use regulations of both jurisdictions is
required.
Conceptual Rendering of I‐5 Bridges
This proposal is for Phase II of the Willamette River I‐5 Replacement Bridge project which includes
construction of the replacement bridges within ODOT right‐of‐way, and related work outside the right‐
of‐way. The focus of the Planning Commission’s evaluation will be on those activities and development
that will occur outside of the ODOT right‐of‐way where the city has planning and regulatory jurisdiction.
These activities include landscaping, re‐vegetation, restoration and mitigation; permanent
bicycle/pedestrian path improvements; and stormwater management facilities serving the bridge
facility.
The outline below provides a list of major activities that will occur in Phase II. Phase I activities are also
shown for context. Proposed work occurring within ODOT (state‐owned) ROW is provided for
informational purposes to allow the reader a comprehensive understanding of the proposal and work
planned. City jurisdiction covers those activities outside of ODOT right‐of‐way.
Attachment 1-3
Overview of Project Phases I and II
Phase II activities will involve the following components:
Outside of ODOT ROW and Within Springfield Jurisdiction
Bicycle/pedestrian path improvements within the Eastgate Woodlands area owned by
Willamalane Park and Recreation District.
Landscaping, re‐vegetation, restoration, and mitigation
Stormwater treatment facilities receiving runoff from bridge related facilities.
Within ODOT ROW
Demolition of detour bridges
Construction of roadway approaches and reconstruction of north bound off‐ramp
Construction of new bridges and miscellaneous structures
Removal of temporary work bridges
Aesthetic improvements
Permanent park, bicycle/pedestrian path, and pedestrian bridge improvements (Eastgate
Woodlands)
Landscaping, re‐vegetation, restoration, and mitigation
Stormwater treatment facilities
Phase I activities involve the following components:
Outside of ODOT ROW and Within Springfield Jurisdiction
Development of temporary construction staging areas and access routes
Construction of temporary bicycle/pedestrian paths in the Whilamut Natural Area (Eugene) and
Eastgate Woodlands
Temporary reconfiguration of bicycle/pedestrian paths in the Eastgate Woodlands
Permanent reconfiguration of a bicycle/pedestrian path along the south side of the Willamette
River
Associated site utilities and stormwater treatment facilities
Temporary landscaping and re‐vegetation
Within ODOT ROW
Construction of temporary work bridges
Installation of cofferdams to enclose the new bridge sub‐structure
Demolition of the decommissioned Willamette River Bridge
Construction of new bridge sub‐structures
Construction of temporary and permanent bicycle/pedestrian paths
Project Timing
The Phase II work described in this application is planned to take up to three years. Construction will
begin in 2010 and continue through 2012. Demolition of the existing bridges and construction of the
new facilities will require four summers of in‐water work, which is only allowed from June 1 to October
31.
Attachment 1-4
Location and Ownership
The Phase II project site is comprised of state‐owned right‐of‐way (ROW), state‐owned property, and
park land owned by Willamalane Park and Recreation District. The majority of the project site is within
state‐owned ROW associated with I‐5, the Willamette River corridor, and Franklin Boulevard. Within
Springfield jurisdiction, Phase II work is proposed on three parcels; Tax Lot No. 101 (Map No. 17‐03‐33‐
41) and Tax Lot No. 100 and 2600 (Map No. 17‐03‐33‐44). Phase II improvements are not proposed on
any of the remaining parcels within Springfield’s jurisdiction.
Proposed Bike/Pedestrian Path Improvements in Eastgate Woodlands Park
Attachment 1-5
Anticipated Impacts of Phase II Activities
During Phase II construction of the replacement bridges, removal of the temporary bridge and
restoration of the impacted riparian areas will be the primary activities. These activities will have both
environmental and aesthetic impacts. These impacts will be evaluated as part of the Willamette
Greenway DU permitting process. The anticipated impacts and changes include: parks and open space;
and traffic and roadway impacts (interstate and local); floodway/floodplain; water quality; stormwater
management; vegetation removal and habitat impacts; and impacts on fish and wildlife. Many of these
impacts are a continuation of those identified as part of Phase I. As such, many of the findings will be
similar
III. Procedural Requirements
Section 3.3‐315 of the Springfield Development Code (SDC) states that development proposals within
the Willamette Greenway Boundary shall be reviewed under Discretionary Use procedure as specified in
Section 5.9‐100, and the Site Plan Review process as specified in Section 5.17‐100.
While this application is for a Willamette Greenway Discretionary Use Permit (Type III procedure),
additional permits that are processed administratively under Type II procedures are paralleling this
proposal. A Site Plan Review Application, Tree‐felling permit and a Floodplain Overlay District permit
will each be reviewed and approved by staff. Staff review of these additional permits will go into
greater technical detail than that called for by the Discretionary Use action.
SDC Section 5.9‐115 states that Discretionary Uses are to be processed as a Type III review procedure
that comes before the Planning Commission. Typically, a Discretionary Use application is processed
concurrently with a Site Plan application. At the Director’s discretion, the Discretionary Use application
may be processed first.
Type III processing steps are described in 5.1‐135 and 5.9‐115. The following processing steps are
required:
1. The Director must determine that the application is complete.
2. Newspaper notice must be provided and mailed notice to property owners and occupants
within 300 feet of the project area.
3. The Director shall distribute the application to the Development Review Committee or the
Historical Commission for comments, where applicable.
4. Notice shall be given to the Oregon Department of Transportation by forwarding a copy of the
application by certified mail, return receipt requested. Notice of final City action shall also be
provided to the Oregon Department of Transportation.
Procedural Findings and Conclusion
Finding #1. A pre‐submittal meeting was held on September 11, 2009. The Applicant’s submittal
was reviewed by members of the Development Review Committee and comments were received to
address completeness issues. The nature of Phase II project activities presents few issues compared to a
Attachment 1-6
project outside of a right‐of‐way that involves a significant structure with connections to water and
sewer services. As such staff completeness comments were limited. The submittal was essentially
complete.
Finding #2. Mailed notice to affected property owners and occupants within 300‐feet of the project
on November 3, 2009 as attested by affidavit. The mailing provided the required notice for both the Site
Plan Review application and the Willamette Greenway Discretionary Use hearing. The mailing allowed
more than the required 20 days notice and complied with the content requirements for Type II public
hearings listed in SDC Section 5.2‐115 (A).
Finding #3. Notice was sent to participants in the Development Review Committee and a meeting
was held on November 17, 2009 to review issues of compliance of the proposal with applicable
development policies and standards.
Finding #4. Comments from Development Review Committee participants are included in the
findings and conditions of approval that are contained in the remainder of this report.
Finding #5. Staff issued a letter affirming the completeness of the submission for processing the
Discretionary Use application on November 19, 2009.
Finding #6. Published notice of the hearing appeared in the Register Guard on November 7, 2009.
The published notice complied with the content requirements for Type II public hearings listed in SDC
Section 5.2‐115 (B).
Finding #7. No written or mailed comments were received. One request for information was
received and provided to a resident with property within the City of Eugene’s planning jurisdiction.
Finding #8. The project area does not fall within the Springfield Historical District and the nature of
the demolition and paving work during Phase I does not warrant Design Review Committee review.
Finding #9. The Applicant is the Oregon Department of Transportation (ODOT). Notice of the
proposed project was forwarded to ODOT on November 19, 2009 as required by SDC 5.1‐135.
Conclusion
The procedural requirements detailed in SDC Section 5.9‐115, SDC Section 5.2‐115 (A) and (B), and SDC
5.1‐135.
IV. Review Criteria
The Willamette Greenway Setback boundary for this project was set when the detour bridge was
constructed in 2004. A significant portion of the SDC Section 3.3‐325 is devoted to the criteria for
establishing the Greenway Setback. Since the setback has been established, the review shall focus on
the impacts of the proposed Phase II activities using the discretionary use provisions of the Springfield
Development Code as required by SDC Section 3.3‐315.
Attachment 1-7
This report shall address portions of the Greenway Setback criteria described in SDC Section 3.3‐325 for
the purpose of providing the Planning Commission more detailed information about the environmental
and aesthetic impacts of Phase II activities as required by SDC 3.3‐330.
DISCRETIONARY USE
As mentioned above, SDC Section 3.3‐315 requires Willamette Greenway Overlay District applications to
be processed using a Discretionary Use process. SDC Section 5.9‐120 lists the review criteria for
approving discretionary uses. Staff has inserted findings addressing these review criteria in the body of
the quoted criteria. The section states ” A Discretionary Use may be approved only if the Planning
Commission or Hearings Official finds that the proposal conforms with the Site Plan Review approval
criteria specified in Section 5.17‐125, where applicable, and the following approval criteria:”
“A. The proposed use conforms with applicable:
1. Provisions of the Metro Plan;
Finding #10. Metro Plan policy D.5 states: “New development that locates along river corridors and
waterways shall be limited to uses that are compatible with the natural, scenic, and environmental
qualities of those water features.” The policy most often applies to new structures (commercial,
industrial, residential, etc.)built along the river. As it applies to replacing the Willamette River I‐5
bridges, this report examines the potential impacts of Phase I of the project on the river, focusing
primarily on the environmental impacts, and evaluating the mitigation of those impacts.
Finding #11. Metro Plan policy D.11 states: “The taking of an exception shall be required if a non‐
water‐dependent transportation facility requires placing of fill within the Willamette River Greenway
setback.”
On July 21, 2008, the Springfield City Council, together with the City of Eugene and Lane County,
adopted an ordinance (No. 6227) amending the Metro Plan text including an exception to Statewide
Planning Goal 15 that “authorizes construction and later removal of one or more temporary work
bridges; demolition of the decommissioned I‐5 Willamette River Bridge, Canoe Canal Bridge, and detour
bridges; construction of two replacement bridges; reconstruction of the roadway approaches to the
bridges (I‐5 and ramps); rehabilitation of the project area and completion of any required mitigation of
project impacts. In association with these tasks, the exception further authorizes within the Willamette
River Greenway Setback line the addition and removal of fill within ODOT right‐of‐way and removal of fill
within a temporary slope easement east of I‐5. This exception satisfies the criteria of Oregon
Administrative Rule (OAR) 660‐004‐0022(6), Willamette Greenway, and the exception requirements of
OAR 660‐004‐0020 Goal 2 Part II(c) for a ‘reasons’ exception and pursuant to OAR 660‐004‐0015, is
hereby adopted as an amendment to the Metro Plan text, Policy D.11, Chapter III, Section D. (Metro Plan
pg. III‐D‐5).”
Finding #12. The amendment to the Metro Plan policy D.11 on July 21, 2008 provides a specific basis
for establishing that the proposed bridge replacement project and its component phases and activities
are consistent with the Metro Plan. Specifically, it allows:
1. The intensification of use and development proposed by the bridge replacement project and
associated multi‐use path and park facility improvements;
Attachment 1-8
2. The siting of non water‐dependent or water‐related uses within the Greenway setback line;
and
3. The placing of fill for a non water‐dependent transportation facility within the Greenway
setback line.
2. Refinement plans;
Finding #13. The Glenwood Refinement Plan applies to the south end of the replacement bridge.
The Glenwood Refinement Plan was first adopted in 1986 when Glenwood was within Eugene’s planning
jurisdiction. The Plan was revised to comport with Springfield planning policies and adopted in
November 1999, after planning jurisdiction for the Glenwood area was transferred to Springfield.
Finding #14. The Glenwood Refinement Plan assumes the existence of the I‐5 Bridge and its policies
do not comment on the bridge per se. The land use designations specified for the project area within
Glenwood are “Public Land,” reflecting state ownership of not only the I‐5 right‐of‐way, but also the
state motor pool site which is adjacent to the staging area for work on the south end of the bridge
within Springfield’s jurisdiction. The City of Springfield owns a residential property near the corner of
Jenkins Rd. and Franklin that will be impacted by construction traffic for the staging and demolition
activities. The residence itself will not be affected. The Lane County Waste Transfer Facility is also
located nearby the staging area, but is not affected by the planned work. Other nearby land is
designated “Light‐Medium Industrial.” These properties include industrial users on Judkins Rd. These
businesses will not be directly impacted by Phase II activities.
3. Plan District standards;
4. Conceptual Development Plans or
5. Specific Development Standards in this Code;”
Finding #15. No “Plan District Standards”, “Conceptual Development Plans” or “Specific
Development Standards” apply to this project. As with other elements of the Discretionary Use review
criteria found in SDC Section 5.9‐120, Section B. (“The site under consideration is suitable for the
proposed use…”) is not easily applied to the bridge replacement project. However, the following
findings are made as they do apply to the proposed Phase II project activities.
“B. The site under consideration is suitable for the proposed use, considering:
1. The location, size, design and operating characteristics of the use (operating
characteristics include but are not limited to parking, traffic, noise, vibration, emissions, light,
glare, odor, dust, visibility, safety, and aesthetic considerations, where applicable);”
Finding #16. The location of the replacement bridge project has been long established by the existing
alignment of I‐5. Joint action by Eugene, Springfield and Lane County in July 2008 has established the
project as a legitimate activity within the Willamette Greenway at the proposed location.
Attachment 1-9
“2. Adequate and safe circulation exists for vehicular access to and from the proposed
site, and on‐site circulation and emergency response as well as pedestrian, bicycle and transit
circulation;”
Finding #17. Construction access to the project site is provided from state‐owned property adjacent
to Jenkins Drive, extending south from Franklin Boulevard. In Phase I, the Applicant constructed a
temporary access route extending from this property to the access the south side of the project site.
Besides Franklin Boulevard, no other streets or roads within Springfield will be directly impacted by the
Phase II work and the proposal will not impact on‐site vehicular circulation or emergency response.
Finding #18. Staging activities and occasional closures will be required on I‐5 and local roadways
during construction. It is anticipated that Franklin Blvd. will be closed for brief periods and traffic will be
detoured as a result. These closures and traffic control will be required to provide movement of
construction equipment and traffic in/out construction sites, as well as during demolition of several
existing bridge spans. Pedestrian and bike traffic will be detoured around the construction site work
areas immediately adjacent I‐5 and along the Willamette River and rerouted on new temporary and
permanent alignments.
Finding #19. ODOT representatives have met with City staff to discuss how to coordinate on a Traffic
Management Plan (TMP). The Plan will provide the details behind the development of Traffic Control
Plan (TCP) and other measures that will be put in place for the construction of the project, as well as to
minimize disruptions to motorists, the freight industry and communities, without compromising public
or worker safety, or the quality of work being performed. The Applicant has submitted a diagram
depicting how temporary closure of the I‐5 off‐ramps may be handled.
“3. The natural and physical features of the site, including but not limited to, riparian
areas, regulated wetlands, natural stormwater management/drainage areas and wooded
areas shall be adequately considered in the project design; and”
Finding #20. The Glenwood Slough is located nearby the project area and will be a receiving stream
for runoff from the bridges when they are completed. The Glenwood Slough an inventoried wetland on
the Springfield Local Wetland Inventory (Site W20) and on the Springfield Natural Resources Inventory
(Site E39).
Finding #21. City staff has met with ODOT representatives to discuss potential stormwater impacts of
the project on the Glenwood Slough at the time Phase I activities were being considered. In Phase II, as
with Phase I the proposed activities will have few permanent impacts. Land Alteration and Drainage
permits (LDAP), as required will be secured after site plan review. LDAPs provide assurance that
temporary runoff related to construction during Phase II construction will be pre‐treated prior to release
into the Glenwood Slough or other drainageways and the Willamette River.
Finding #22. Public Works Staff made the following finding regarding the Phase II stormwater
management: “The storm water analysis and design submitted appears to meet the minimum
requirements of the City of Springfield Engineering Design Standards and Procedures Manual for water
quantity and water quality requirements.”
Attachment 1-10
Figure 1. Natural Features Protection—Glenwood Slough Vicinity
Figure 2. Natural Features Protection—Eastgate Woodlands
Attachment 1-11
Finding #23. Figure 1. depicts the potential impacts of Phase II work on the Glenwood Slough and
vicinity. As can be seen from the diagram, wetland and streams have been identified and efforts will be
made to avoid unnecessary impacts.
Finding #24. Figure 2. shows the potential impacts to the Eastgate Woodlands (a portion of which
includes the Whilamut Natural Area). Wetland impacts are largely avoided in the Eastgate Woodland.
Wetland features are present in the Eastgate Woodlands (Sites W11, W13) but impact to these wetland
sites has been largely avoided. The Applicants Exhibit F—Wetland Delineation Reports, details the
location of wetlands and streams in or near the project area.
Finding #25. For Phase I, the Applicant provided a floodplain analysis showing that the floodplain
would be expanded to a minimal degree in the event of a 100‐year flood event when the work bridge
structures are in place to facilitate bridge demolition and replacement bridge construction. Exhibit 3 is a
diagram showing the existing FEMA floodplain boundary in the vicinity of the project. The map also
shows the small area of floodplain expansion that would occur in the Eastgate Woodlands area.
Finding #26. Phase II construction and completion of the replacement bridges will reduce the
structural presence in the river and reduce the contribution of the bridges to any future flood event.
Finding #27. Subsequent to the Planning Commission approval of the Phase I Discretionary Use
application, the Applicant submitted a Floodplain Overlay Development application. That application
included analysis of the flood hazard impacts of both Phase I and Phase II activities. Staff approved the
Floodplain development permit based in part on FEMA’s issuance of a “Certification of No‐Rise
Determination, dated January 21, 2009 for Phases I and II of the project.
“4. Adequate public facilities and services are available, including but not limited to,
utilities, streets, storm drainage facilities, sanitary sewer and other public infrastructure.”
Finding #28. The project does not involve the extension of public utilities or expansion of existing
storm drainage facilities. Streets in the vicinity of the project site are adequate to serve construction
access requirements.
“C. Any adverse effects of the proposed use on adjacent properties and on the public can be
mitigated through the:
“1. Application of other Code standards (including, but not limited to: buffering from less
intensive uses and increased setbacks);”
Finding #29. Typical mitigation measures do not apply to this proposal. Careful, coordinated
planning between ODOT, ODOT representatives, City staff, and Willamalane staff will help minimize
disruption to citizens and impacts to natural resource assets during Phase II construction activities.
“2. Site Plan Review approval conditions, where applicable;”
Finding #30. Site Plan Review has been completed and the findings of that review are included in the
findings of this report.
Attachment 1-12
Finding #31. The following “Conditions of Approval” are recommended to the Planning Commission
for their consideration:
Condition of Approval #1: Lane closures should not be performed along Franklin Boulevard during the
northbound or southbound I‐5/Franklin Boulevard ramp closures, nor during a special events listed in
the project’s Traffic Management Plan (TMP), such as the Eugene Marathon, major University of Oregon
sporting events, major holidays, etc. without specific permission from the City of Springfield Traffic
Engineer.
Condition of Approval #2: Apply for and obtain an encroachment permit from the city for use the use of
our right of way in placing detour signs.
Condition of Approval #3: Coordinate with the City of Springfield Transportation Staff, and on the Final
Site Plan show a modified design of the curve on the south side of the Canoe Canal, east of the bridge’s
centerline, that will meet AASHTO’s (American Association of State Highway and Transportation
Officials) guidelines by modifying the curve, striping and/or signing it in accordance with the MUTCD
(Manual of Uniform Traffic Control Devices).
Condition of Approval #4: All construction related activities for the proposed bridge replacement shall
protect in place the existing 30” sanitary sewer pipe crossing at the south end of the existing bridge.
“3. “Other approval conditions that may be required by the Approval Authority; and/or”
Finding #32. A Joint Application Form was filed by the Applicant seeking permission from the U.S.
Army Corps of Engineers and the Oregon Department of State Lands to conduct construction activities
that may impact wetland and riparian resources in the project area. On May 22, 2009, the US Army
Corps of Engineers issued a “Notice to Proceed” letter authorizing the construction activities proposed
by Phase II.
Finding #33. ODOT has already secured other state and federal permits related to water quality, fish
and wild life protection as part of the federal National Environmental Protection Act (NEPA) review
which is required for all protects using federal funds.
“4. A proposal by the applicant that meets or exceeds the cited Code standards and/or
approval conditions.”
Finding #34. The application documents protections and mitigation initiatives which are intended to
avoid or minimize impacts to the community and to its natural resource assets. Additional actions or
conditions of may be required by the Planning Commission for approving this proposal.
Conclusion: The Applicant has submitted a detailed description of the proposed activities and the likely
impacts that will stem from those activities. Based on the discretionary use review criteria found in SDC
Section 5.9‐120, staff finds that these review criteria have been substantially met.
Attachment 1-13
Willamette Greenway Setback Standards (SDC 3.3‐325)
“A. Local, regional and State recreational needs shall be provided for consistent with the
carrying capacity of the land. The possibility that public recreation use might disturb adjacent
property shall be considered and minimized to the greatest extent possible.”
Finding #35. The Eastgate Woodlands and eastern portion of the Whilamut Natural Area of Alton
Baker Park are within the project area. These park lands include walking trails and bike paths including
the North Bank Trail which extends along the Willamette River though the Whilamut Natural Area and
the Eastgate Woodlands. The southeast loop of Pre’s Trail is located within the Whilamut Natural Area
with an extension to the Eastgate Woodlands. There are additional connecting paths throughout the
Whilamut Natural Area, on the Knickerbocker Bridge, and along Franklin Boulevard.
Finding #36. The Applicant proposes to conduct minor reconstruction and improvement of the trail
system in the Eastgate Woodlands. The improvements are proposed to facilitate bicycle and pedestrian
movements through the project area during and following construction. The improvements have been
developed in coordination with the Willamalane Park and Recreation District (WPRD) and the Whilamut
Natural Area Citizen’s Planning Committee (CPC).
Finding #37. Paths and trails will, to the maximum extent practicable, be kept open, safe, and
useable during construction. A continuous route across state‐owned right‐of‐way for the
bicycle/pedestrian pathways will be kept open and accessible at all times on both the north side, and to
the extent practicable, the south side of the river during construction.
Finding #38. The Applicant has provided evidence of extensive coordination with Willamalane Park
and Recreation District regarding potential impacts and mitigation measures within and the Eastgate
Woodlands. Based on this coordination, a comprehensive program of mitigation measures has been
proposed by the Applicant. These mitigation measures are discussed in Section 5.1 and incorporated by
reference herein.
“B. Adequate public access to the river shall be provided.”
Finding #39. The proposed Phase II activities include improvements to some trails and bike paths,
particularly in the Eastgate Woodlands area, a park owned by Willamalane Park and Recreation District.
No new barriers to appropriate river access are proposed.
“C. Significant fish and wildlife habitats shall be protected.”
Finding #40. According to ODFW, two salmonid populations listed under the Endangered Species Act
(ESA) are documented as occurring within the reach of the Willamette River that flows through the
project area:
▪ Upper Willamette River spring Chinook (Oncorhynchus tshawytscha) and critical habitat –
federally threatened (FT)
▪ Columbia River bull trout (Salvelinus confluentus) Distinct Population Segment (DPS) and critical
habitat – FT
Attachment 1-14
Finding #41. The Applicant indicates that construction activities will require in‐water work and are
anticipated to require four in‐water work periods. Temporary effects from in‐water work will include
construction or removal of piling/piers, which involves site preparation, pile driving, dewatering and
isolation, and re‐watering once work is complete. Work area isolation will require fish capture and
release operations in the Willamette River, which would affect both listed and non‐listed fish species.
All fish capture and release operations will be conducted by experienced biologists following guidelines
established by ODFW and NMFS.
Finding #42. A species list provided to the Applicant by Oregon Natural Heritage Information Center
(ONHIC) indicated that there are no federal‐ or state‐listed ESA terrestrial wildlife species known to
reside within the project area. This finding is supported by findings made by the Springfield natural
Resources Study in 2005. There are reports of sensitive or species of concern terrestrial wildlife within
two miles of the project area; however there is habitat that would support only one of these sensitive
species in the project area (i.e., the northwestern pond turtle).
Finding #43. There is a great blue heron rookery (which may have become inactive) along the Canoe
Canal located about 800 feet east of the project area. Eugene Parks and Willamalane staffs have noted
the ephemeral ponds located throughout the Whilamut Natural Area of Alton Baker Park provide
habitat for amphibian species. Western meadowlark nesting habitat has been documented in the
vicinity of the meadow immediately northwest of the project area.
Finding #44. To avoid fish and wildlife species and minimize temporary impacts from construction
activities, all applicable OTIA III State Bridge Delivery Program EPS will be implemented to reduce the
extent of direct and indirect impacts to fish and wildlife species. The Applicant has detailed these
actions to minimize impacts to fish and wildlife in Section 6.0 of their application narrative. Section 6.0
of their narrative is included with this report as Exhibit 2.
“D. Identified scenic qualities and view‐points shall be preserved.”
Finding #45. This standard is not directly applicable to Phase II activities. The Applicant has described
measures that are being taken to protect natural resource assets in the project area for both
environmental and aesthetic reasons.
“E. The maintenance of public safety and protection of public and private property,
especially from vandalism and trespass shall be provided for, to the maximum extent
practicable.”
Finding #46. Illegal camping and occasional is a current problem that occurs on both the south bank
(Glenwood) and within the Eastgate Woodlands on the north bank. Phase II activities will not increase
these illegal activities. Improvements to the bike path and trail system once Phases II of the bridge
replacement project is complete may reduce some of this activity by encouraging more community use
of the areas for positive purposes.
“F. The natural vegetative fringe along the river shall be enhanced and protected to the
maximum extent practicable.”
Impacts to riparian areas during project construction are unavoidable. The Applicant indicates that
design elements of the project are intended to avoid and minimize impacts as much as feasible.
Attachment 1-15
With the completion of Phase II (the construction of the replacement bridges), landscape and open
spaces areas will be replanted and/or restored to pre‐construction conditions or better. The Applicant
states that the project will not result in a net loss of landscape areas, open space, or vegetation and will
provide the maximum possible amount of landscape area and open space following completion.
Finding #47. The Applicant’s submittal includes a 12‐page Tree Preservation and Removal Plan
(Sheets L0.3 through L3.6) and a 19‐page Landscape Plan (Sheets L0.1 through L2.6). In addition, the
submittal includes a Riparian Area Protection Report prepared by Mason, Bruce and Girard, an
environmental consulting firm. These documents, together describe a riparian protection and
restoration and replanting plan for the project. The proposed measures are deemed adequate by staff
to minimize disturbance to existing riparian vegetation and to restore areas disturbed by construction
activities.
Typical Riparian Planting and Filter Strip Near Bike Path
Finding #48. In addition to local permitting, the Applicant states that continued coordination state
and federal permitting agencies will be maintained to minimize the impacts to riparian vegetation during
construction and operational activities. The Applicant will continue coordination with resource
agencies (federal, state, and local) and implement OTIA III EPS, obtain regulatory permits (DSL Removal‐
Attachment 1-16
Fill, USACE Section 404), provide site restoration and compensatory mitigation, and identify additional
opportunities to minimize disturbances and enhance restoration. To avoid and minimize impacts
additional mitigation measures will be implemented to reduce the extent of direct and indirect impacts
to riparian vegetation.
Finding #49. Section 6.0 of the application narrative describes the mitigation measures proposed to
protect natural vegetation in the project area. Section 6.0 of the Applicant’s narrative is included in this
report as Exhibit 2.
“G. The location of known aggregate deposits shall be considered. Aggregate extraction
may be permitted outside the Greenway Setback Area subject to compliance with State law,
the underlying zoning district and conditions of approval designed to minimize adverse effects
on water quality, fish and wildlife, vegetation, bank stabilization, stream flow, visual quality,
quiet and safety and to guarantee reclamation.”
Finding #50. No inventoried aggregate resources will be affected by this project.
“H. Developments shall be directed away from the river to the greatest possible degree;
provided, however, lands committed to urban uses shall be permitted to continue as urban
uses, including port, public, industrial, commercial and residential uses, uses pertaining to
navigational requirements, water and land access needs and related facilities.”
Finding #51. The location of the replacement bridges are dictated by the alignment of I‐5. The
substance of this standard does not apply to this project.
Conclusion: The Applicant has submitted a detailed description of the proposed activities and the likely
impacts that will stem from those activities. Based on the discretionary use review criteria found in SDC
Section SDC 3.3‐325, staff finds that these review criteria have been substantially met.
Based on a review of the Applicant’s proposal, staff has made many findings which support a conclusion
that the Applicant has generally satisfied the review criteria for a Willamette Greenway Discretionary
Use Permit found in Section 3.3‐325 and 5.9‐120.
SDC Section 5.9‐115 states that “typically a Discretionary Use application is reviewed concurrently with a
Site Plan application. The following section of this report includes the approval criteria, findings and
conclusions of the Site Plan Review analysis that was completed by staff concurrent with the Willamette
Greenway Discretionary Use review.
IV. SITE PLAN REVIEW CRITERIA OF APPROVAL
The approval criteria for Site Plan Review are found in SDC Section 5.17‐125.
SDC 5.17‐125 Criteria for Site Plan Approval:
A. The zoning is consistent with the Metro Plan diagram, and/or the applicable Refinement Plan
diagram, Plan District map, and Conceptual Development Plan.
Attachment 1-17
B. Capacity requirements of public and private facilities, including but not limited to, water and
electricity; sanitary sewer and stormwater management facilities; and streets and traffic safety
controls shall not be exceeded and the public improvements shall be available to serve the site
at the time of development, unless otherwise provided for by this Code and other applicable
regulations. The Public Works Director or a utility provider shall determine capacity issues.
C. The proposed development shall comply with all applicable public and private design and
construction standards contained in this Code and other applicable regulations.
D. Parking areas and ingress‐egress points have been designed to: facilitate vehicular traffic, bicycle
and pedestrian safety to avoid congestion; provide connectivity within the development area
and to adjacent residential areas, transit stops, neighborhood activity centers, and commercial,
industrial and public areas; minimize driveways on arterial and collector streets as specified in
this Code or other applicable regulations and comply with the ODOT access management
standards for State highways.
E. Physical features, including, but not limited to: steep slopes with unstable soil or geologic
conditions; areas with susceptibility of flooding; significant clusters of trees and shrubs;
watercourses shown on the WQLW Map and their associated riparian areas; other riparian areas
and wetlands specified in Section 4.3‐117; rock outcroppings; open spaces; and areas of historic
and/or archaeological significance, as may be specified in Section 3.3‐900 or ORS 97.740‐760,
358.905‐955 and 390.235‐240, shall be protected as specified in this Code or in State or Federal
law.
The applicable standards and policies found in the Springfield Development Code (SDC) and the current
Springfield Engineering Design Standards and Procedures Manual provide the basis for the findings
conditions and conclusions shown below. Other authoritative local state and federal standards may also
be applied as applicable to this proposal.
As mentioned above, the Development Review Committee reviewed the proposed plans and supporting
information on November 17, 2009. The staff’s review comments have been incorporated as “Findings”
and “Conditions” in this report. The focus of this report is on those elements of the site plan that are
not in compliance with Springfield’s development policies and standards. The report will not account
for all of the site plan details that are in compliance with the policies and standards.
Site Plan Review Criteria
“A. The zoning is consistent with the Metro Plan Diagram, and/or the applicable Refinement Plan
diagram, Plan District map, and Conceptual Development Plan.”
Zoning is Consistent with the Metro Plan/Refinement Plans—Permitted Uses – SDC 3.2‐710 and SDC
3.2‐410
Finding #52. The Metro Plan is a framework plan which incorporates more detailed planning
documents which include neighborhood plans or special area studies that address issues that are unique
to a specific geographical area. These neighborhood plans provide more detailed analysis and planning
direction than the Metro Plan. These planning documents are adopted as subsets of the Metro Plan and
are assumed to more specifically represent the intention of the Metro Plan for these specific areas.
Attachment 1-18
Finding #53. The Glenwood Refinement Plan is a neighborhood plan that was first adopted in 1986
when Glenwood was within Eugene’s planning jurisdiction. The Plan was revised to comport with
Springfield planning policies and adopted in November 1999, after planning jurisdiction for the
Glenwood area was transferred to Springfield.
Finding #54. Much of the proposed activity will occur within ODOT right‐of‐way which has no zoning.
Work within the Glenwood area (south bridgehead) will affect lots zoned Light Medium Industrial. Work
within the Eastgate Woodlands will occur within an area zoned Public Land and Open Space. The
proposed Phase I staging, bridge demolition, and bike path improvements within these areas are
consistent with these zoning districts.
Finding #55. The Glenwood Refinement Plan (Subarea 4) applies to the south bridgehead of the
replacement bridge. The Glenwood Refinement Plan assumes the existence of the I‐5 Bridge and its
policies do not comment on the bridge per se. The land use designations specified for the project area
within Glenwood are “Public Land,” reflecting state ownership of not only the I‐5 right‐of‐way, but also
the state motor pool site which is adjacent to the staging area for work on the south end of the bridge
within Springfield’s jurisdiction. The City of Springfield owns a residential property near the corner of
Jenkins Rd. and Franklin that will be impacted by construction traffic for the staging and demolition
activities. The residence itself will not be affected.
The Lane County Waste Transfer Facility is also located nearby the staging area, but is not affected by
the planned work. Other nearby land is designated “Light‐Medium Industrial.” These properties include
industrial users on Judkins Rd. These businesses will not be directly impacted by Phase I activities.
Finding #56. Policy 1. of the Plan Diagram section of the Glenwood Refinement Plan (Subarea 4)
states: “This subarea is appropriate for light‐medium industrial use. “ The zoning for the Glenwood
(south bridgehead) is Light‐Medium Industrial (see page 25 of the Glenwood Refinement Plan).
Finding #57. No refinement plan exists for the Eastgate Woodlands area (north bridgehead area).
Willamalane Park and Recreation District owns the land within which ODOT has agreed to make
improvements to the existing bike path. The area is zoned Public Land and Open Space. Willamalane
Finding #58. Much of the proposed activity will occur within ODOT right‐of‐way which has no zoning.
The proposed Phase II bridge construction and bike path improvements within the Glenwood and
Eastgate Woodlands areas are consistent with the Light Medium Industrial and Public Land and Open
Space zoning for these areas.
Finding #59. The Willamalane Park and Recreation Comprehensive Plan was adopted by the City of
Springfield on November 15, 2004 as a refinement plan of the Metro Plan. Lane County also adopted
the Plan on October 10, 2004. The Plan identifies the Eastgate Woodlands as a Natural Area Park.
Base Zone and Special Use Development Standards—SDC 3.2‐715 and SDC 3.2‐420
The base zone and special use development standards do not apply to the proposed Phase I activities.
The planned construction staging, bridge demolition, and bike path improvements are public
improvements like streets and sidewalks that are infrastructure facilities not covered by the table of
base zone development standards found in SDC Sections 3.2‐715 and SDC 3.2‐420.
Attachment 1-19
Applicable Overlay District Requirements—SDC5.17‐125 A
DRINKING WATER PROTECTION OVERLAY DISTRICT
SDC Section 3.2‐425 G.4. states: Proposed development utilizing hazardous materials that may impact
groundwater quality shall be as specified in section 3.3‐200.
Finding #60. The site location falls outside of the 99‐year time of travel zone for any wellhead shown
on the Springfield Drinking Water Protection Area Map. The project is therefore not subject to the
Drinking Water Protection Area Overlay District standards.
FLOODPLAIN OVERLAY DISTRICT
Finding #61. FIRM Panel Number 41039C166F shows the project area is affected by the floodplain
(Willamette River, Glenwood Slough).
Finding #62. The Applicant has provided preliminary information showing that the floodplain would
be expanded to a minimal degree in the event of a 100‐year flood event when the work bridge
structures are in place to facilitate bridge demolition and replacement bridge construction. Exhibit 3 is a
diagram showing the existing FEMA floodplain boundary in the vicinity of the project. The map also
shows the small area of floodplain expansion that would occur in the Eastgate Woodlands area.
Conclusion: The proposal satisfies Site Plan Criterion A.
“B. Capacity requirements of public and private facilities, including but not limited to, water and
electricity; sanitary sewer and stormwater management facilities; and streets and traffic
safety controls shall not be exceeded and the public improvements shall be available to serve
the site at the time of development, unless otherwise provided for by this Code and other
applicable regulations. The Public Works Director or a utility provider shall determine capacity
issues.”
C. The proposed development shall comply with all applicable public and private design and
construction standards contained in this Code and other applicable regulations.
The staff analysis required to determine findings for Criterion B and C include significant overlap. For
the purposes of this review, Criteria B and C are considered together in this section of the staff report.
The elements of the Springfield Development Code which apply to Criterion B and Criterion C include
but are not limited to:
• Infrastructure Standards for Transportation—SDC 4.2‐100
• Infrastructure Standards for Utilities—SDC 4.3‐100
• Landscaping, Screening and Fence Standards—SDC 4.4‐100
• On Site Lighting Standards—SDC 4.5‐100
• Fence Standards – SDC 4.4‐115
• Specific Development Standards—SDC 4.7‐100
Attachment 1-20
Infrastructure Standards for Transportation—SDC 4.2‐100
TRANSPORTATION SYSTEM IMPACTS
SDC Section 4.2‐100 through 4.2‐160 details infrastructure standards for streets, sidewalks, driveways,
accessways, pedestrian trails and related transportation facilities. Additional design standards for
transportation facilities are found in the Engineering and Design Standards and Procedures Manual and
the City of Springfield Construction Standard Specifications Section(s) 317, 501, and 502, and Standard
Drawings 5‐1 to 5‐25. These documents provide specific design standards for streets and accessways.
Parking standards are found in SDC Section 4.6‐100. SDC Section 5.17‐125 requires site plans to address
transportation design issues in conjunction with SDC 4.2‐100 and with the Engineering and Design
Standards and Procedures Manual.
Finding #63. SDC 5.17‐130 (F) states that conditions may include “Limiting the hours of operation
whenever a land use conflict is identified by the Director or a party of record, including, but not limited
to: noise and traffic generation.”
Finding #64. SDC 5.19 establishes criteria for discretionary uses. SDC 5.9‐120(B)(2) states that to
determine suitability of the site for the proposed use one must consider the following: “Adequate and
safe circulation exists for vehicular access to and from the proposed site, and on‐site circulation and
emergency response as well as pedestrian, bicycle and transit circulation.”
Finding #65. During construction and demotion of the bridges the number traffic lanes along Franklin
Boulevard may be reduced and, for a time, completely shut down. This will cause motorists not only to
take the planned detour route, which is owned in part by the City of Springfield (the southern section of
Glenwood Boulevard), but also to impact Springfield streets as people try to avoid the imposed
congestion. The pedestrian and bicyclists may also be impacted by the project.
Finding #66. The Project‐Level Traffic Management Plan (TMP) was submitted with this application in
Exhibit G. On Page 6, Table 3 incorrectly includes the City of Eugene as having jurisdiction over parts of
Glenwood Drive. The correct agencies are Springfield and Lane County. Springfield has jurisdiction over
the southern half of Glenwood Drive, while Lane County residing over the northern portion.
Finding #67. In the TMP’s Exhibit G on Page 19, Table 6 lists Holidays and Events in the Project Area.
The following event should be added to that list: Eugene Marathon (May 2, 2010 (See
http://www.eugenemarathon.com —and annually near the first week of May)
Condition of Approval #1: Lane closures should not be performed along Franklin Boulevard during the
northbound or southbound I‐5/Franklin Boulevard ramp closures, nor during a special events listed in
the project’s Traffic Management Plan (TMP), such as the Eugene Marathon, major University of Oregon
sporting events, major holidays, etc. without specific permission from the City of Springfield Traffic
Engineer.
Condition of Approval #2: Apply for and obtain an encroachment permit from the city for use the use of
our right of way in placing detour signs.
Finding #68. On Sheets L2.3 and C1.3, the asphalt path on the south side of the Canoe Canal shows
the asphalt path within three feet of the retaining wall. That retaining wall and the slope ascending
Attachment 1-21
south of it limit the line of site for bicyclists rounding the corner of that path which lies just east of the
overhead I‐5 bridge. According AASHTO’s 1999 Guide for the Development of Bicycle Facilities, the
stopping site distance provided at this corner is inadequate. See Figure 3.
Condition of Approval #3: Coordinate with the City of Springfield Transportation Staff, and on the Final
Site Plan show a modified design of the curve on the south side of the Canoe Canal, east of the bridge’s
centerline, that will meet AASHTO’s (American Association of State Highway and Transportation
Officials) guidelines by modifying the curve, striping and/or signing it in accordance with the MUTCD
(Manual of Uniform Traffic Control Devices).
Finding #69. Franklin Blvd. is the street facility that will be most impacted by lane closures. Franklin
is a state highway facility managed by ODOT. The TMP shows plans for diverting traffic onto Glenwood
Blvd. to handle traffic while the I‐5 on‐ramps and off ramps from Franklin Blvd. are closed for
reconstruction.
Figure 3. Bike Path and Retaining Wall near the Canoe Canal
Attachment 1-22
The proposed retaining wall may cause insufficient sight distance for cyclists traveling on the paved
bike (orange). The yellow path is a bark covered jogging path (See Finding #69).
Finding #70. According to the TMP, a weekday closure of Franklin Boulevard would cause the
Franklin/Glenwood and others intersection to fail to meet ODOT’s mobility standards, and the queues at
these intersections would exceed the available storage. Also, concurrent closures of Franklin Boulevard
and either of the I‐5 ramp closures (south bound or north bound I‐5/Franklin Blvd.) would cause
undesirable traffic congestion.
Proposed Detour Routes
Attachment 1-23
SITE ACCESS AND CIRCULATION
Finding #71. Construction access to the project site will be provided from state‐owned property
adjacent to Jenkins Drive, extending south from Franklin Boulevard. The Applicant proposes to
construct a temporary access route extending from this property to the access the south side of the
project site. Besides Franklin Boulevard, no other streets or roads within Springfield will be directly
impacted by the Phase II work and the proposal will not impact on‐site vehicular circulation or
emergency response.
Finding #72. Staging activities and occasional closures will be required on I‐5 and local roadways
during construction. It is anticipated that Franklin Blvd. will be closed for brief periods and traffic will be
detoured as a result. These closures and traffic control will be required to provide movement of
construction equipment and traffic in/out construction sites, as well as during demolition of several
existing bridge spans. Pedestrian and bike traffic will be detoured around the construction site work
areas immediately adjacent I‐5 and along the Willamette River and rerouted on new temporary and
permanent alignments.
Finding #73. ODOT has included a proposed Traffic Management Plan (TMP) with this application.
The Plan details a Traffic Control Plan (TCP) and other measures that will be put in place for the
construction of the project, as well as to minimize disruptions to motorists, the freight industry and
communities, without compromising public or worker safety, or the quality of work being performed
PUBLIC STREETS, SIDEWALKS & IMPROVEMENT AGREEMENTS
Finding #74. Phase II bridge construction will not impact or require public street improvements
outside of ODOT right‐of‐way.
Infrastructure Standards for Utilities—SDC 4.3‐100
SDC Section 4.3‐100 through 4.3‐145 details infrastructure standards for sanitary sewers, stormwater
systems, water quality protection, natural resource protection, water and electric utilities, and public
easements. Additional design standards for these facilities are found in the Springfield Engineering and
Design Standards and Procedures.
Sanitary Sewer Improvements – SDC 4.3‐105
SDC Section 4.3‐105.A requires that sanitary sewers shall be installed to serve each new development
and to connect developments to existing mains. Additionally, installation of sanitary sewers shall provide
sufficient access for maintenance activities.
SDC Section 4.3‐105.C requires that proposed sewer systems shall include design consideration of
additional development within the area as projected by the Metro Plan. Section 2.02.1 of the City’s
Engineering Design Standards and Procedures Manual (EDSPM) states that when land outside a new
development will logically direct flow to sanitary sewers in the new development, the sewers shall be
public sewers and shall normally extend to one or more of the property boundaries.
Attachment 1-24
Section 4.3‐105.A of the SDC requires that sanitary sewers shall be installed to serve each new
development and to connect developments to existing mains. Additionally, installation of sanitary
sewers shall provide sufficient access for maintenance activities.
Finding #75. The Phase II bridge project will not require new sewer service or modifications to the
existing sanitary sewer. With the exception of one sanitary sewer (30” pipe) crossing at the south end of
bridge, there appears to be no other sanitary sewer systems in the vicinity that will impact the proposed
bridge construction.
Condition of Approval #4: All construction related activities for the proposed bridge replacement shall
protect in place the existing 30” sanitary sewer pipe crossing at the south end of the existing bridge.
Storm Water Management – SDC 4.3‐110
SDC Section 4.3‐110.B states: The Approval Authority shall grant development approval only where
adequate public and/or private stormwater management systems provisions have been made as
determined by the Public Works Director, consistent with the Engineering Design Standards and
Procedures Manual (EDSPM).
Section 4.3‐110.C of the SDC states that a stormwater management system shall accommodate
potential run‐off from its entire upstream drainage area, whether inside or outside of the development.
SDC Section 4.3‐110.D requires run‐off from a development to be directed to an approved stormwater
management system with sufficient capacity to accept the discharge.
SDC Section 4.3‐110.E requires new developments to employ drainage management practices which
minimize the amount and rate of surface water run‐off into receiving streams and promote water
quality.
Finding #76. Phase II storm water impacts will be minimal due to the nature and location of the
proposed improvements. All permanent and temporary impervious multi‐use pathways will be designed
to sheet flow across filtration strips and infiltrate directly into the surrounding landscape in accordance
with local design standards. The temporary work bridge will be constructed beneath the existing I‐5
bridges and will have little impact on storm water collection and runoff.
Finding #77. To comply with Sections 4.3‐110.D & E, existing storm water runoff from the site will be
maintained and storm water from all new bike path impervious areas will directed into water quality
filter strips prior to discharge into the public system. The proposed vegetative filter strips complies with
storm water quality requirements.
Finding #78. The Applicant has indicated that Phase II will address the storm water management
requirements for the bridge replacement and new impervious areas to include bio‐slopes, grassy swales,
bio‐infiltration swales, and dry detention ponds.
Finding #79. The plans submitted indicates that storm water runoff from the bridge roadway will be
collected and discharged to three storm water facilities. The southbound swale outfalls to a culvert
which empties into an existing ditch that connects with the Canoe Canal. The southbound bio‐retention
pond empties into the Canoe Canal. The northbound swale outfalls to an existing culvert that passes
beneath I‐5 and joins the runoff from the southbound swale. South of the river, the bridges, I‐5
Attachment 1-25
roadway and ramps will drain to four storm water facilities. All of the facilities empty into the unnamed
tributary through the site that lows to the Willamette River. The swale beneath the northbound span of
the Willamette River Bridge collects runoff from the northbound bridge, treats the water, and then
conveys it to the unnamed tributary.
The swale at the corner of the northbound off ramp and Riverview Avenue treats contributing areas
from Franklin Blvd and sections of the off ramp outside the project limits. The bio‐retention pond
between the southbound on ramp and the northbound off ramp collects and treats the majority of the
site runoff south of the Willamette River Bridge high point where pond outfalls beneath the northbound
off ramp into the unnamed tributary. The swale in the northbound side ditch near the southern project
limits collects and treats runoff from the contributing area on I‐5 up to the Glenwood interchange.
Runoff in the northbound side ditch empties into the unnamed tributary after passing through the
swale.
Typical Swale Planting
Finding #80. The storm water analysis and design submitted appears to meet the minimum
requirements of the City of Springfield Engineering Design Standards and Procedures Manual for water
quantity and water quality requirements.
Finding #81. The Glenwood Slough is located nearby the project area and will be a receiving stream
for runoff from the bridges when they are completed. The Glenwood Slough an inventoried wetland on
the Springfield Local Wetland Inventory (Site W20) and on the Springfield Natural Resources Inventory
(Site E39).
Attachment 1-26
Finding #82. City staff has met with ODOT representatives to discuss potential stormwater impacts of
the project on the Glenwood Slough. Phase II activities will have few permanent impacts. Land
Alteration and Drainage permits (LDAP), as required will be secured after site plan review. LDAPs
provide assurance that Phase II construction will be pre‐treated prior to release into the Glenwood
Slough or other drainageways and the Willamette River.
Water Quality Protection – SDC 4.3‐115
Under Federal regulation of the Clean Water Act (CWA), Endangered Species Act (ESA), and National
Pollutant Discharge Elimination System (NPDES), the City of Springfield has obtained a Municipal
Separate Storm Sewer System (MS4) permit. A provision of this permit requires the City demonstrate
efforts to reduce the pollution in urban stormwater to the Maximum Extent Practicable (MEP).
Federal and Oregon Department of Environmental Quality (ODEQ) rules require the City’s MS4 plan
address six “Minimum Control Measures.” Minimum Control Measure 5, “Post‐Construction
Stormwater Management for New Development and Redevelopment,” applies to the proposed
development.
Minimum Control Measure 5 requires the City of Springfield to develop, implement and enforce a
program to ensure the reduction of pollutants in stormwater runoff to the MEP. The City must also
develop and implement strategies that include a combination of structural or non‐structural Best
Management Practices (BMPs) appropriated for the community.
Minimum Control Measure 5 requires the City of Springfield use an ordinance or other regulatory
mechanism to address post construction runoff from new and re‐development projects to the extent
allowable under State law. Regulatory mechanisms used by the City include the Springfield
Development Code (SDC), the City’s Engineering Design Standards and Procedures Manual (EDSPM) and
the future Stormwater Facilities Master Plan (SFMP).
As required in Section 4.3‐110.E of the SDC, “a development shall be required to employ drainage
management practices approved by the Public Works Director and consistent with Metro Plan policies
and the Engineering Design Standards and Procedures Manual.”
Section 3.02 of the City’s EDSPM states the Public Works Department will accept, as interim design
standards for stormwater quality, water quality facilities designed pursuant to the policies and
procedures of either the City of Portland (BES), or the Clean Water Services (CWS).
Finding #83. Section 3.03.3.B of the City’s EDSPM states all public and private development and
redevelopment projects shall employ a system of one or more post‐developed BMPs that in
combination are designed to achieve at least a 70 percent reduction in the total suspended solids in the
runoff generated by that development. Section 3.03.4.E of the manual requires a minimum of 50
percent of the non‐building rooftop impervious area on a site shall be treated for stormwater quality
improvement using vegetative methods. The Applicant has demonstrated that this requirement will be
met where all new impervious areas will discharge to the mentioned existing water quality swale.
Finding #84. To meet the requirements of the City’s MS4 permit, the Springfield Development Code,
and the City’s EDSPM, the Applicant has proposed discharging to the existing private vegetative water
quality swale. The existing private vegetative swale is located at the north /east end of property. The
Attachment 1-27
Applicant has submitted a storm water management plan that includes a review of the existing water
quality swale for receiving the additional impervious areas and demonstrating compliance.
Finding #85. The Applicant has included a plan and seed mix for enhancing the existing swale
functionality by tilling and seeding the bottom of the water quality swale. The proposed improvements
to the existing bioswale will meet the City’s storm water quality requirements.
Finding #86. The Applicant submitted an operations and maintenance plan to the City for the long‐
term maintenance and operation of the existing water quality swale and is found to be acceptable by
Public Works.
Drinking Water Protection Standards—SDC 3.3‐235
The Drinking Water Protection (DWP) Overlay District is established to protect aquifers used as potable
water supply sources by the City from contamination. This Section establishes procedures and standards
for the physical use of hazardous materials harmful to groundwater within TOTZ by new and existing
land uses requiring development approval.
Finding #87. The site location falls outside of the 99‐year time of travel zone for any wellhead shown
on the Springfield Drinking Water Protection Area Map. The project is therefore not subject to the
Drinking Water Protection Area Overlay District standards.
Natural Resources Protection– SDC 4.3‐117
The proposed development embraces the Willamette River and has impacts on the Glenwood Slough,
the Augusta Channel, and on small wetland areas within the Eastgate Woodlands Area. These features
are inventoried resource sites identified on the Springfield Local Wetlands Inventory, Springfield
Inventory of Natural Resource Sites and on the Springfield Water Quality Limited Watercourse Map.
SDC Section 4.3‐117 (D) states, “Site Plan Review as specified in Section 5.17‐100 shall be required for
commercial, industrial and multi‐unit residential developments which are proposed within 150‐feet of a
locally significant wetland or riparian area.”
SDC Sections 4.3‐115 and 4.3‐117 describe protection standards for “Water Quality Limited
Watercourses” and for riparian resource areas. These protections include a combination of
development setbacks and in some cases, restoration requirements.
Finding #88. The Glenwood Slough is located nearby the staging area for the project and portions of
the resource could be impacted by Phase II activities. The Glenwood Slough is an inventoried wetland
on the Springfield Local Wetland Inventory (Site W20) and on the Springfield Natural Resources
Inventory (Site E39).
Finding #89. Figure 1 below, depicts the potential impacts of Phase II work on the Glenwood Slough
and vicinity. As can be seen from the diagram, wetland and streams have been identified and efforts
will be made to avoid unnecessary impacts.
Finding #90. A Joint Application Form was filed by the Applicant seeking permission from the U.S.
Army Corps of Engineers and the Oregon Department of State Lands to conduct construction activities
Attachment 1-28
that may impact wetland and riparian resources in the project area. On May 22, 2009, the US Army
Corps of Engineers issued a “Notice to Proceed” letter authorizing the construction activities proposed
by Phase II.
Finding #91. Figure 2 below, shows the potential impacts to the Eastgate Woodlands (a portion of
which includes the Whilamut Natural Area). Wetland impacts are largely avoided in the Eastgate
Woodland. Wetland features are present in the Eastgate Woodlands (Sites W11, W13) but impact to
these wetland sites has been largely avoided. The Applicants Exhibit F—Wetland Delineation Reports,
details the location of wetlands and streams in or near the project area.
Finding #92. The Eastgate Woodlands and eastern portion of the Whilamut Natural Area of Alton
Baker Park include walking trails and bike paths including the North Bank Trail which extends along the
Willamette River though the Whilamut Natural Area and the Eastgate Woodlands. The southeast loop
of Pre’s Trail is located within the Whilamut Natural Area with an extension to the Eastgate Woodlands.
There are additional connecting paths throughout the Whilamut Natural Area, on the Knickerbocker
Bridge, and along Franklin Boulevard.
Finding #93. The Applicant proposes to conduct minor reconstruction and improvement of the trail
system in the Eastgate Woodlands. The improvements are proposed to facilitate bicycle and pedestrian
movements through the project area during and following construction. The improvements have been
developed in coordination with the Willamalane Park and Recreation District (WPRD) and the Whilamut
Natural Area Citizen’s Planning Committee (CPC).
Finding #94. Paths and trails will, to the maximum extent practicable, be kept open, safe, and
useable during construction. A continuous route across state‐owned right‐of‐way for the
bicycle/pedestrian pathways will be kept open and accessible at all times on both the north side, and to
the extent practicable, the south side of the river during construction.
Finding #95. The Applicant has provided evidence of extensive coordination with Willamalane Park
and Recreation District regarding potential impacts and mitigation measures within and the Eastgate
Woodlands. Based on this coordination, a comprehensive program of mitigation measures has been
proposed by the Applicant.
Finding #96. A Joint Application Form was filed by the Applicant seeking permission from the U.S.
Army Corps of Engineers and the Oregon Department of State Lands to conduct construction activities
that may impact wetland and riparian resources in the project area. On May 22, 2009, the US Army
Corps of Engineers issued a “Notice to Proceed” letter authorizing the construction activities proposed
by Phase II.
Finding #97. ODOT has already secured other state and federal permits related to water quality, fish
and wild life protection as part of the federal National Environmental Protection Act (NEPA) review
which is required for all protects using federal funds.

Attachment 1-30
Finding #98. According to ODFW, two salmonid populations listed under the Endangered Species Act
(ESA) are documented as occurring within the reach of the Willamette River that flows through the
project area:
▪ Upper Willamette River spring Chinook (Oncorhynchus tshawytscha) and critical habitat –
federally threatened (FT)
▪ Columbia River bull trout (Salvelinus confluentus) Distinct Population Segment (DPS) and critical
habitat – FT
Finding #99. The Applicant indicates that construction activities will require in‐water work and are
anticipated to require four in‐water work periods. Temporary effects from in‐water work will include
construction or removal of piling/piers, which involves site preparation, pile driving, dewatering and
isolation, and re‐watering once work is complete. Work area isolation will require fish capture and
release operations in the Willamette River, which would affect both listed and non‐listed fish species.
All fish capture and release operations will be conducted by experienced biologists following guidelines
established by ODFW and NMFS.
Finding #100. A species list provided to the Applicant by Oregon Natural Heritage Information Center
(ONHIC) indicated that there are no federal‐ or state‐listed ESA terrestrial wildlife species known to
reside within the project area. This finding is supported by findings made by the Springfield natural
Resources Study in 2005. There are reports of sensitive or species of concern terrestrial wildlife within
two miles of the project area; however there is habitat that would support only one of these sensitive
species in the project area (i.e., the northwestern pond turtle).
Finding #101. There is a great blue heron rookery (which may have become inactive) along the Canoe
Canal located about 800 feet east of the project area. Eugene Parks and Willamalane staffs have noted
the ephemeral ponds located throughout the Whilamut Natural Area of Alton Baker Park provide
habitat for amphibian species. Western meadowlark nesting habitat has been documented in the
vicinity of the meadow immediately northwest of the project area.
Finding #102. To avoid fish and wildlife species and minimize temporary impacts from construction
activities, all applicable OTIA III State Bridge Delivery Program EPS will be implemented to reduce the
extent of direct and indirect impacts to fish and wildlife species. The Applicant has detailed these
actions to minimize impacts to fish and wildlife in Section 5.7 and 5.8 of their approved Willamette
Greenway Discretionary Use (SH2008‐00009) application narrative (See Exhibit 2).
Finding #103. Impacts to riparian areas during project construction are unavoidable. The Applicant
indicates that design elements of the project are intended to avoid and minimize impacts as much as
feasible. Prior to completion of the Phase II (the construction of the replacement bridges) , landscape
and open spaces areas will be replanted and/or restored to pre‐construction conditions or better. The
Applicant states that the project will not result in a net loss of landscape areas, open space, or
vegetation and will provide the maximum possible amount of landscape area and open space following
completion.
Finding #104. The site plan shows that less than 5 trees outside of the ODOT right‐of‐way shall be
removed during Phase II activities. The Applicant shall not be required to submit a Tree‐Felling Permit
for vegetation removal associated with Phase II activities.
Attachment 1-31
Finding #105. In addition to local permitting, the Applicant states that continued coordination state
and federal permitting agencies will be maintained to minimize the impacts to riparian vegetation during
construction and operational activities. The Applicant will continue coordination with resource
agencies (federal, state, and local) and implement OTIA III EPS, obtain regulatory permits (DSL Removal‐
Fill, USACE Section 404), provide site restoration and compensatory mitigation, and identify additional
opportunities to minimize disturbances and enhance restoration. To avoid and minimize impacts
additional mitigation measures will be implemented to reduce the extent of direct and indirect impacts
to riparian vegetation.
Finding #106. Section 5.6 of the approved Willamette Greenway Discretionary Use Permit describes
the mitigation measures proposed to protect natural vegetation in the project area. Exhibit 2 is a
diagram outlining the natural features protection measures.
Utilities, Fire Protection and Public Easements – SDC 4.3‐120 through 4.3‐140
SDC Section 4.3‐130 (A) states that each development area shall be provided with a water system having
sufficiently sized mains and lesser lines to furnish an adequate water supply to the development with
sufficient access for maintenance.
SDC Section 4.3‐130 (B) states that fire hydrants and mains shall be installed by the developer as
required by the Fire Marshal and the utility provider.
Finding #107. The Applicant has indicated there are utilities that will require relocation that includes
water and telephone lines and is coordinating with Springfield Utility Board (SUB) and Eugene Water,
Electric Board (EWEB), and Qwest regarding these utilities.
Finding #108. The proposed development sites have adequate fire and emergency access. During
Phase I, the Applicant installed a fire hydrant in the construction staging area to comply with SDC
Section 4.3‐130 (B).
Finding #109. The site plan application for the Phase II bridge construction does not appear to require
or indicate new utilities or new easements and appears to have no impact to existing utilities,
easements, or right‐of‐way.
Landscaping, Screening and Fence Standards—SDC 4.4‐100 through 4.4‐115
SDC Section 4.4‐100 through 4.4‐115 details standards and requirements for landscaping, screening and
fencing for new developments. Section 4.110 (A) lists those instances where screening is required.
The typical landscape and screening standards do not apply to this proposal. Impacts to riparian areas
during project construction are unavoidable. The Applicant indicates that design elements of the project
are intended to avoid and minimize impacts as much as feasible.
With the completion of Phase II (the construction of the replacement bridges), landscape and open
spaces areas will be replanted and/or restored to pre‐construction conditions or better. The Applicant
states that the project will not result in a net loss of landscape areas, open space, or vegetation and will
provide the maximum possible amount of landscape area and open space following completion.
Attachment 1-32
Finding #110. The Applicant’s submittal includes a 12‐page Tree Preservation and Removal Plan
(Sheets L0.3 through L3.6) and a 19‐page Landscape Plan (Sheets L0.1 through L2.6). In addition, the
submittal includes a Riparian Area Protection Report prepared by Mason, Bruce and Girard, an
environmental consulting firm. These documents, together describe a riparian protection and
restoration and replanting plan for the project. The proposed measures are deemed adequate by staff
to minimize disturbance to existing riparian vegetation and to restore areas disturbed by construction
activities.
Lighting and Glare‐ SDC 3.2‐425g.3., SDC4.3‐110 G., SDC 4.5‐110
SDC Section 4.5‐110 A. states: All exterior light fixtures shall be shielded or recessed so that direct glare
and reflection are contained within the boundaries of the property, and directed downward and away
from abutting properties; public rights of way; and riparian, wetlands and other protected areas
identified in this Code on the same property.
SDC Section 4.5‐110B.2.b. states that the height of a free standing exterior light fixture within 50 feet of
riparian area shall not exceed 12 feet. SDC Section 4.3‐110 G requires a developer to employ site design,
landscaping and drainage management practices to protect and restore riparian area functions.
Finding #111. The cut sheet details on the lighting plan (Sheet E 1.2) call for cut‐off lighting fixtures to
be used for exterior lighting, consistent with Code requirements.
Vehicle Parking, Loading And Bicycling Parking Standards—SDC 4.6‐100
SDC Section 4.6 details development standards for vehicle parking, loading and bicycle parking.
Section 4.6‐125, (Table 4.6‐3) identifies the minimum required off street parking for various land uses.
Finding #112. Vehicle parking and bicycle access for the Eastgate Woodlands Natural Park already
exists. The proposed improvements outside of the ODOT right‐of‐way do not require additional vehicle
parking or bicycle parking. This standard does not apply to the proposal.
Conclusion: As conditioned, the public and private improvements are sufficient to serve the
proposed development. The proposed site plan satisfies this sub‐element of the Criteria B
and C.
“D. Parking areas and ingress‐egress points have been designed to: facilitate vehicular traffic,
bicycle and pedestrian safety to avoid congestion; provide connectivity within the
development area and to adjacent residential areas, transit stops, neighborhood activity
centers, and commercial, industrial and public areas; minimize driveways on arterial and
collector streets as specified in this Code or other applicable regulations and comply with the
ODOT access management standards for State highways.”
Traffic Standards
The Engineering and Design Standards and Procedures Manual and the City of Springfield Construction
Standard Specifications Section(s) 317, 501, and 502, and Standard Drawings 5‐1 to 5‐25 provide design
Attachment 1-33
standards for streets and accessways. These standards are supplemented by the parking standards
found in SDC Section 4.6‐100.
Section 4.2‐105.G.2 of the Springfield Development Code requires that whenever a proposed land
division or development will increase traffic on the City street system and that development has any
unimproved street frontage abutting a fully improved street, that street frontage shall be fully improved
to City specifications. Exception (i) notes that in cases of unimproved streets, an Improvement
Agreement shall be required as a condition of Development Approval postponing improvements until
such time that a City Street improvement project is initiated.
Finding #113. The proposed development does not include new parking or ingress and egress points
on to public streets. This standard does not apply.
Conclusion: The proposed site plan satisfies Criterion D.
“E. Physical features, including, but not limited to: steep slopes with unstable soil or geologic
conditions; areas with susceptibility of flooding; significant clusters of trees and shrubs;
watercourses shown on the WQLW Map and their associated riparian areas; other riparian
areas and wetlands specified in Section 4.3‐117; rock outcroppings; open spaces; and areas of
historic and/or archaeological significance, as may be specified in Section 3.3‐900 or ORS
97.740‐760, 358.905‐955 and 390.235‐240, shall be protected as specified in this Code or in
State or Federal law.”
The City of Springfield maintains various inventories of locally significant physical features which may
require protection or which may have an impact on the safety of the proposed development. Among
these inventories are the Springfield Inventory of Natural Resource Sites, the Springfield Map of Water
Quality‐Limited Watercourses, Springfield Inventory of Historic Places, Springfield Local Wetland
Inventory and others.
Finding #114. The proposed development embraces the Willamette River and has impacts on the
Glenwood Slough, the Augusta Channel, and on small wetland areas within the Eastgate Woodlands
Area. These features are inventoried resource sites identified on the Springfield Local Wetlands
Inventory, Springfield Inventory of Natural Resource Sites and on the Springfield Water Quality Limited
Watercourse Map.
Finding #115. The submitted site plan and approved Willamette Greenway Discretionary Use Plan has
included details describing the protection measures that will be afforded to affected resource sites.
These protection details are described in earlier contained in this report (Finding #86 through Finding
#106). Those findings support the conclusion that identified natural resource features will be
adequately protected during the course of this project.
Conclusion: The proposed site plan satisfies Criterion E.
Conclusion: The proposed site plan as conditioned, can be made to conform to the Type II
Site Plan Review criteria found in SDC 5.17‐125 (A)‐(E).

Exhibit 1-1
Summary of Phase II Work and Restoration/Mitigation Efforts
The following material is an excerpt from Section 4 of the applicant’s submittal describing the proposed
work and restoration and mitigation efforts.
I. Phase II Work Summary
The Proposal involves Phase II construction activities, as described below, and identified by applicable
jurisdiction (Eugene or Springfield). Phase I of the Project, the subject of a prior approved WG and SDR
application (WG 08‐4, SDR, 08‐7), involves only: development of construction access routes and staging
areas; removal of the decommissioned Willamette River Bridge, including construction of a temporary
work bridge; construction of new bridge sub‐structures; installation of cofferdams to enclose the new
bridge sub‐structure; reconstruction of I‐5 SB on‐ramp; and reconfiguration and construction of bicycle
and pedestrian path improvements to maintain public access along the river.
Following is a detailed summary of Phase II activities:
Willamette River Bridge
The Proposal involves construction of a new crossing over the Willamette River. The new crossing will
be composed of two bridges; one dedicated to carrying NB traffic and the other carrying SB traffic. The
new bridges will be constructed in the same general location as the existing bridges. The new bridges
will be slightly higher (approximately 5‐feet) than the decommissioned bridge to provide more clearance
over Franklin Boulevard as well as meet current vertical clearance requirements for state highways and
railroads.
The configuration of each proposed structure is nearly identical. The proposed bridge structures are
1,760 feet long (SB) and 1,985 feet long (NB). The proposed bridges will each be approximately 67.5
feet wide. The bridges are composed of three structure types from north to south: a cast‐in‐place
concrete girder span (approach span); two concrete deck arch spans over the Willamette River
(Willamette River Bridge); and several spans of cast‐in‐place concrete box girders over Franklin
Boulevard, UPRR, and the NB exit ramp from I‐5 to Franklin Boulevard (approach spans). As noted
above, the arches are configured in two spans, with 390 feet for the north span and 416 feet for the
south span. The bridges will be supported by three bents founded on drilled shafts. Bent locations were
established through the prior approved Phase I application (WG 08‐4, SDR 08‐7).
The concrete deck arch bridge type proposed is aesthetically classic. Modern engineering and
construction techniques enable concrete deck arches to be built with slender arch ribs and without
bracing, making them more sleek and uncluttered in appearance. Slenderness provides added aesthetic
appeal due in part to an implicit understanding by the public that such structures, although light and
graceful, are also strong and durable. This understanding has evolved by the incremental increases of
noteworthy structures in the built environment that have trended toward slenderness. The deck arch
design employs a relatively lightweight floor system for concrete. The proposed arch ribs are slender in
Attachment 1-38
Exhibit 1-2
profile view, but deeper perpendicular to their axis. This appearance reinforces their role aesthetically
as the supporting elements of the spans.1
The new NB and SB bridges will be constructed in two stages over a four‐year period. Stage 1 (2009‐
2011) involves demolition of the decommissioned bridge (Phase I), construction of the SB bridge, and
demolition of the detour bridge. Stage 2 (2011‐2012) involves construction of the NB bridge, removal of
temporary work bridges, falsework, and cofferdams, and associated site restoration and mitigation.
Approach Spans
The Proposal involves construction of several approach spans to connect the proposed concrete deck
arch bridge to the I‐5 roadway. On the north side of the Willamette River, a single concrete girder span
will connect the I‐5 roadway to the concrete deck arch bridge. On the south side of the Willamette
River, seven concrete girder spans will be elevated over Franklin Boulevard, UPRR, and the NB exit ramp
from I‐5 to Franklin Boulevard, to connect the concrete deck arch bridge to the I‐5 roadway. The
approach spans use a deck and girder system that appears visually similar to the arch spans. This
thematic consistency leads to a clear appearance of the whole structure.
Canoe Canal Bridge
The Proposal involves replacement of the Canoe Canal crossing. The proposed bridge is a single
structure, 180 feet long by 140.5 feet wide at the northern end and 146.5 feet wide at the southern end.
The structure will be supported on driven steel pile end bents. The new alignment will shift slightly west
of the existing alignment and will fully span the Canoe Canal. The proposed project will not affect
hydraulics through the bridge opening.
Demolition of Detour Bridge
The Proposal involves demolition of the Detour Bridge. Demolition of the decommissioned bridge is a
component of the Phase I approval. The Applicant’s contractor will remove the detour bridge in 2011
following the completion of the SB bridge. Once completed, the SB bridge will maintain both directions
of traffic until the NB bridge is completed. The removal of in‐water components of the detour bridge
will occur during the ODFW established in‐water work period (IWWP). 2 The detour bridge has six bents
within the Willamette River. Prior to removal of the bents in the Willamette River, the Applicant’s
contractor will install precast concrete barriers upstream and downstream and a U‐shaped floating
turbidity curtain downstream of the work area to deflect flows and trap sediment.
I‐5 NB Off‐Ramp (NB Exit Ramp to Franklin Boulevard)
The Proposal involves reconstruction of the NB Exit Ramp (off‐ramp) to Franklin Boulevard.
Reconstruction of the SB On‐Ramp to I‐5 is a component of the Phase I approval. The NB off‐ramp will
be reconstructed horizontally and vertically in generally the same location, with minor shifts in
alignment, from the Riverview Street intersection to its departure from I‐5 (approximately 1,900 feet).
The reconstruction will consist of a single‐lane ramp with a 16‐foot travel lane.

Attachment 1-39
Exhibit 1-3
Several miscellaneous structures, including soundwalls and retaining walls, are required in support of
the replacement of the Willamette River Bridge. Following is a brief description of each structure,
including location and applicable jurisdictional boundaries.
Northbound Soundwall #21124 (Anderson Lane Subdivision)
The Proposal includes a soundwall along I‐5 NB, west of the Anderson Lane Subdivision in Springfield. As
illustrated on Sheet A4.0A Retaining Wall Elevations and Sections (Exhibit C), the soundwall is 720 feet
long and nominally 16 to 17 feet in height. The soundwall is located entirely within state‐owned ROW
and within Springfield. A small segment of the soundwall, roughly 34 feet, extends into the Willamette
Greenway.
Southbound Soundwall #21130 (Laurel Hill Subdivision)
The Proposal includes a soundwall along I‐5 SB, east of the Laurel Hill subdivision in Eugene. The
soundwall is 1800 feet long and nominally 12 to 16 feet high. The soundwall height varies in along its
length, in‐line with I‐5. The soundwall is located in Eugene, outside WG and /WR boundaries, and
entirely within state‐owned ROW. The soundwall is detailed in the Phase I submittal.
Retaining Wall #21125 (Canoe Canal)
The Proposal includes a retaining wall along the south embankment of the Canoe Canal Bridge and the
east embankment of the I‐5 mainline. As illustrated on Sheet A4.0A Retaining Wall Elevations and
Sections (Exhibit C), the wall is 536 feet long and 3 to 6 feet high. The retaining wall is located in Eugene
and Springfield, within the WG boundary, outside /WR boundaries, and entirely within state‐owned
ROW.
Retaining Wall #21127 (Between NB Off‐ramp and the I‐5 Mainline)
The Proposal includes a retaining wall along the south abutment of the Willamette River Bridge to
provide grade separation between the finish grade for NB I‐5 and the NB off‐ramp, as the ramp drops
below the bridge south abutment. As illustrated on Sheet A4.0A Retaining Wall Elevations and Sections
(Exhibit C), the wall is 645 feet long and a maximum height at the south abutment of 24 feet, reducing to
approximately 15 feet at the south end. The wall is located in Eugene and Springfield, outside the WG
boundary, and entirely within state‐owned ROW.
Retaining Wall #21128 (Along the Temporary Fill Slope)
The Proposal includes a retaining wall located roughly five feet from the east ROW boundary of I‐5,
adjacent to the NB off‐ramp. As illustrated on Sheet A4.0 Retaining Wall Elevations and Sections (Exhibit
C), the proposed wall is 350 feet long and nominally 6 to 12 feet high. The purpose of the retaining wall
is to contain the proposed finished grade and restore/remove an existing embankment. The wall is
located in Springfield, outside the WG boundary, and entirely within state‐owned ROW.
Retaining Wall #21129 (Along Side of NB Off‐ramp)
The Proposal includes a retaining wall to protect the unnamed tributary associated with Glenwood
Slough drainage that parallels the NB ramp alignment and continues through an existing pipe culvert
flowing northward. As illustrated on Sheet A4.0 Retaining Wall Elevations and Sections (Exhibit C), the
proposed wall is 415 feet long and 6 to 12 feet high. The wall is located in Springfield, outside the WG
boundary, and entirely within state‐owned ROW. Retaining wall studied as part of the Hydraulics
Report. The conclusion was that the wall will not cause any impacts or increased flooding.
Attachment 1-40
Exhibit 1-4
Stairway and Stepping Stones (Eastgate Woodlands)
The Proposal includes a stairway, composed of gravel and concrete, and an enhancement area,
consisting of basalt boulders and concrete stepping stones organized in a grid pattern, located in the
Eastgate Woodlands. The stairway is proposed to provide an access route from the bark path
underneath North Walnut Bridge to the surface of the bridge. The stepping stones are proposed as an
aesthetic enhancement. The stairway and stepping stones are located in Springfield, within the WG
boundary.
Pedestrian Bridge at Restored Stream Channel
The Proposal includes two pedestrian bridges crossing the restored stream channel on the south side of
the Willamette River. The northern bridge includes two spans and forms the beginning of the proposed
Millrace Ruins Path. The southern bridge is a single span and will serve the reconstructed South Bank
Path, located on the south side of Franklin Boulevard. As illustrated on Sheet A7.0 Elevations (Exhibit C),
the pedestrian bridges are approximately 116 feet long and 16 feet wide. The bridges are located in
Eugene, within the WG boundary, partly within /WG boundaries, and entirely within state‐owned ROW.
Bicycle/Pedestrian Path and Trail Improvements
As part of the project, permanent improvements to the overall path and trail system in the Project area
are proposed. Following is a brief description of each improvement, including location and applicable
jurisdictional boundaries.
North Walnut Path
The existing North Walnut Path will be slightly realigned and reconstructed within the Project area. This
improvement includes reconstruction of the connecting segment between North Walnut Path and
Knickerbocker Pedestrian Bridge. The proposed asphalt path is 12 feet wide. The path is within Eugene
and Springfield, within WG and /WR boundaries, and within both parkland and state‐owned ROW.
North Walnut Path to Canoe Canal Path
The improvement includes reconstruction of the north‐south connector between North Walnut Path
and Canoe Canal Path, located west of the I‐5 Bridge. The reconstruction will follow generally the same
alignment as the existing path. The proposed concrete path is 12 feet wide. The path is within Eugene,
within the WG boundary, partly within /WR boundaries, and entirely within state‐owned ROW.
Canoe Canal Path
The existing path beneath the Canoe Canal Bridge will be realigned to straighten it out and improve sight
distance and safety for path users. The proposed path realignment moves the path from its present
location between the south edge of the Canoe Canal and the existing south intermediate bent to a
location between the the new bridge end bents. The proposed concrete path is 12 feet wide. The path
is within Eugene and Springfield, within WG and /WR boundaries, and entirely within state‐owned ROW.
North Bank Trail
The existing path along the North Bank will be realigned and reconstructed at its eastern terminus with
North Walnut Path. The proposed concrete path is 12 feet wide. The path is within Eugene, within the
WG boundary, partly within /WR boundaries, and within the Whilamut Natural Area.
Millrace Ruins Path
Attachment 1-41
Exhibit 1-5
The Proposal involves a proposed path along the north side of Franklin Boulevard, extending east from
Knickerbocker Pedestrian Bridge. The proposed path will involve both pier‐based and fill‐based
segments within the Project area and will be 16 feet wide. The path will include a span crossing the
restored stream channel. The path is within Eugene, within WG and /WR boundaries, and entirely
within state‐owned ROW.
South Bank Path
The existing south bank path will be realigned and reconstructed. The path extends east from
Knickerbocker Pedestrian Bridge and accesses the south side of Franklin Boulevard. The proposed
asphalt path is 12 feet wide. The path is within Eugene and Springfield, within the WG boundary, partly
within /WR boundaries, and entirely within state‐owned ROW.
Pre’s Trail (Whilamut Natural Area)
The Proposal involves extensive improvements to Pre’s Trail within the Project area. An existing
segment along the north bank of the Willamette River and the segment extending under Canoe Canal
Bridge will be realigned and reconstructed. The proposed bark trail is 10 feet wide. The trail is within
Eugene and Springfield, within WG boundaries, partly within /WR boundaries, and both within parkland
and state‐owned ROW.
II. Site Restoration
The Project will result in a maximum of approximately 27.9 acres of temporary ground disturbance and
vegetation removal due to grading, staging, and construction access. All temporary disturbed areas
within the Project area will be returned to pre‐construction conditions and planted per Sheets L0.3‐
L0.3D, L3.0‐L3.6 Landscape Plan (Exhibit C).
Within ODOT ROW, site restoration consists of slope stabilization and erosion control through planting,
seeding, and bioengineered streambank structures. Areas disturbed by the Project within the Whilamut
Natural Area (Eugene) will be converted from disturbed grassland into native upland prairie. Site
restoration within the Whilamut Natural Area will also include converting disturbed grassland into
native riparian forest. Disturbed riparian forest within the Eastgate Woodlands (Springfield) will be
returned to pre‐existing conditions.
Native species will be used throughout the Project with the exception of small areas adjacent to
soundwalls and within medians where native‐analog plantings with particular aesthetic and functional
qualities will be incorporated. Native plantings will be installed in areas of less than 2:1 slopes and in
areas throughout ODOT ROW where visual buffers are deemed necessary.
Native grass and forb mixes are proposed to restore environmental functions, such as noxious weed
control, water quality, habitat preservation, and erosion control. All temporarily disturbed wetlands will
be seeded with Wetland seeding mix. All disturbed areas on the north and south banks of the
Willamette River will be restored with the Riparian Plant mix. Several seed mixes will be used
exclusively within the Whilamut Natural Area and Eastgate Woodlands per City of Eugene and City of
Springfield requirements. Native species will be used exclusively within the park and all riparian areas.
Compensatory Mitigation
Attachment 1-42
Exhibit 1-6
The Applicant has purchased 0.05 credits at the West Eugene Wetland Mitigation Bank to compensate
for the permanent loss of a small amount of wetland area and function. Compensatory mitigation for
temporary and permanent waters impacts includes planting and establishment of a 1.9‐acre riparian
forest with the Whilamut Natural Area and 1‐acre of stream and associated riparian area restoration in
the concrete‐lined unnamed tributary of the Willamette River, located south of the river.
The Project will improve fish passage by conducting mitigation to restore the unnamed tributary. The
restoration of the creek’s lower reach involves replacing the overflow channel’s concrete lined banks
with natural stream material (gravel, cobbles and boulders), planting native riparian vegetation along
the fringe of the creek's lower reach, replacing two failed culverts under the pedestrian path with a new
full‐spanning bridge structure, and plugging the culvert under Franklin Boulevard so that the water is
directed down the restored channel. The upland area along the southern tributary will be widened and
flattened to create a wider floodplain and facilitate development of a forested/scrub‐shrub riparian
fringe. Pool and riffle areas will be interspersed at appropriate locations along the channel.
Additional water mitigation will be accomplished by reducing the number of footings currently
associated with the detour and decommissioned bridges within the Willamette River, which equals a
0.03‐acre net reduction of artificial structures.
Aesthetic Enhancements
The Proposal involves a number of proposed aesthetic enhancements within the Project area. Since
Project inception, the CAG and PDT have provided significant input to ODOT on aesthetic enhancement
opportunities. A subset of these members developed an overall theme for the Project ‐ "Whilamut
Passage" ‐ incorporating elements of different places, users, images and languages to guide design and
establish an enduring identity for the area surrounding the bridge. The development of the Whilamut
Passage theme was followed by a sequence of design workshops with local professionals aimed at
creating a palette of aesthetic enhancement opportunities.
The potential opportunities are planned to be designed and detailed by local design/artist teams during
construction of the Project and are therefore included as concepts in the Proposal. Following is a
summary of aesthetic enhancement concepts.
I‐5 Median Sculpture(s)
This item consists of sculptural art piece(s) located within the I‐5 median on the north side of the
Willamette River, between the Canoe Canal Bridge and the Willamette River Bridge. The proposed
median sculpture(s) are located within ODOT ROW and mostly within Springfield; maximum length 420‐
feet, maximum height 30‐feet, and maximum width, 20‐feet.
Willamette River and Canoe Canal Bridge Railings
The proposed Willamette River Bridges will include one of two railing types; a three‐tube open railing or
solid concrete barrier with tubular top railing. The proposed Canoe Canal Bridge will include a solid
concrete railing. Enhancements to the railing may include color choices, railing insets, and/or textures.
Northbound Soundwall Materials
Material choices for the proposed NB soundwall may include use of surface‐mounted or applied durable
materials.
Attachment 1-43
Exhibit 1-7
Canoe Canal Underpass Improvements
Improvements proposed at Canoe Canal consist of a multi‐use path, railing adjacent to Canoe Canal, and
retaining wall. Path railing types under consideration consist of metal, wood, stone, or concrete
material choices. Path surfaces under consideration consist of ADA‐accessible textural pavers, tiles,
painted accents, and/or decorative features embedded within pavement. The retaining wall may
include texture, surface‐mounted, or applied durable materials.
Slope Pavements at Canoe Canal and Willamette River Bridge
The slope embankments underneath the Canoe Canal Bridge and Willamette River Bridges will be paved.
Aesthetic enhancements include alternative pavement materials, decorative features embedded within
pavement, textural enhancement to paving, and color selection.
North Bank Path Enhancements
Aesthetic enhancements to the reconstructed North Bank Path include ADA‐accessible textural pavers,
tiles, painted accents, and/or decorative features embedded within the pavement.
North Bank Interpretive Area
Aesthetic enhancements along the reconstructed North Bank Path include an interpretive kiosk
dedicated to the Confederated Tribes of Grande Ronde, enhanced native upland prairie plantings, and
additional native plantings including native bulbs. The enhancements proposed are within the
Whilamut Natural Area and state‐owned ROW.
North Bank Forest‐Meadow Transition Zone
This aesthetic enhancement involves a forest‐meadow transition zone, consisting of native planting, in
the Whilamut Natural Area.
Union Pacific Railroad Protection Fence
Proposed along the Union Pacific Railroad tracks, this protection fence includes material choices
consisting of chainlink, ornamental iron, or artistic‐design panels. The proposed fence may be extended
along the entire length of the approach spans for continuity. The proposed fence is located entirely
within state‐owned ROW.
Willamette River Bridge Arch Lighting
Aesthetic enhancements to the Willamette River Bridge involve low‐level fiber optic rope lighting along
arch ribs. The single color lighting output will be no more than an average maintained luminance of 0.9
foot‐candle at grade. Proposed lighting design will comply with “dark sky” requirements.
Glenwood Trailhead
This enhancement involves a proposed asphalt parking area with several parking spaces and an
interpretive kiosk. The trailhead is located within state‐owned ROW, in Springfield, and within the WG
boundary. The Kiosk shall be no more than 8‐feet tall and 16‐square feet per face in surface area.
South Bank Millrace and Stream Restoration Interpretive Area
This enhancement involves an interpretive area adjacent to the historic millrace ruins and the proposed
stream restoration of the unnamed tributary on the south side of the Willamette River. The area is
located within state‐owned ROW, in Eugene jurisdiction, and within the WG boundary.
Attachment 1-44
Attachment 1-45
Exhibit 1-8
South Bank Bicycle/Pedestrian Path
Proposed path surfaces under consideration include textural, embedded, or painted aesthetic
enhancements. The path shall maintain ADA‐accessibility.
III. Overview of Proposed Mitigation Measures
The Applicant seeks to preserve scenic, aesthetic, historic, and environmental resources throughout the
proposed Project. The National Environmental Policy Act (NEPA) environmental assessment (EA)
prepared for the Project identifies proposed measures that avoid, minimize, and/or mitigate
environmental impacts.3 In response to the EA, FHWA issued a “finding of no significant effect” (FONSI)
letter for the proposed project on November 25, 2008. Construction activities will follow the best
management practices designed to minimize impacts to resources. Such practices include, but are not
limited to, dust, noise, and erosion control. To avoid, minimize, and/or mitigate the impacts of this
Project, the Applicant proposes the following general measures, among others:
▪ Meet OTIA III Environmental Performance Standards (EPS) in order to meet the requirements of
the programmatic environmental permits that apply to the statewide bridge program. (EPS for
the Project were included in the Phase I application)
▪ Continue public involvement through construction
▪ Plan traffic management to keep all travel modes open and safe during construction
▪ Limit work hours
▪ Limit project noise
▪ Install soundwalls and stormwater management facilities
▪ Restore and enhance affected areas

ODOT. January 2008.
Exhibit 2-1
Phase II Environmental Protection Plans
The Metro Plan Natural Assets and Constraints Working Paper identifies the Willamette River Greenway
in Figure J1 and identifies the Willamette River as a fish spawning river. According to ODFW, two
salmonid populations listed under the Endangered Species Act (ESA) are documented as occurring
within the reach of the Willamette River that flows through the project area:
▪ Upper Willamette River spring Chinook (Oncorhynchus tshawytscha) and Critical Habitat –
federally threatened (FT)
▪ Columbia River bull trout (Salvelinus confluentus) Distinct Population Segment (DPS) and Critical
Habitat – FT
Construction activities will require in‐water work and are anticipated to require four in‐water work
periods. Temporary effects from in‐water work will include construction or removal of piling/piers,
which involves site preparation, pile driving, dewatering and isolation, and rewatering once work is
complete. Work area isolation will require fish capture and release operations in the Willamette River,
which could affect both listed and non‐listed fish species. All fish capture and release operations will be
conducted by experienced biologists following guidelines established by ODFW and NMFS.
A species list provided by ORNHIC indicated that there are no federal‐ or state‐listed ESA terrestrial
wildlife species known to reside within the project area. There are reports of sensitive or species of
concern terrestrial wildlife within two miles of the project area; however there is habitat that would
support only one of these sensitive species in the project area (i.e., the northwestern pond turtle).
There is a great blue heron rookery (which may have become inactive) along the Canoe Canal located
about 800 feet east of the project area. Eugene POS and WPRD staff have noted the ephemeral ponds
located throughout the Whilamut Natural Area of Alton Baker Park provide habitat for amphibian
species. Western meadowlark nesting habitat has been documented in the vicinity of the meadow
immediately northwest of the project area.
To avoid fish and wildlife species and minimize temporary impacts from construction activities, all
applicable OTIA III State Bridge Delivery Program EPS will be followed. Project EPS are included in the
Phase I application. The Applicant proposed additional mitigation measures also identified in the Phase
I approval and incorporated by reference herein.
These findings together with the Plan Set and documentation submitted herewith demonstrate that this
standard has been met to the greatest extent practicable.
I. Vegetation and Habitat Types
Vegetation and habitat types within the project area are generally associated with urban development
or natural/open space areas. The urban developed areas include residential, commercial, and
transportation (roadways and railroads) that have been planted with landscaping. The open space areas
include a combination of forested and emergent wetlands, upland forest (mixed deciduous‐coniferous
type), mixed deciduous‐coniferous riparian, and grassland type habitats that are predominantly
Attachment 1-46
Exhibit 2-2
managed grass areas within the I‐5 corridor. These natural/open space areas are vegetated with a
predominance of native species, although disturbance has allowed encroachment of invasive species.
Some of the most common identified invasive species known to occur within the project area include:
Himalayan blackberry (Rubus armeniacus); Scotch broom (Cytisus scoparius); Pennyroyal (Mentha
pulegium); Tall fescue (Festuca arundinacea); Italian ryegrass (Lolium multiflorum); English ivy (Hedera
helix); Reed canarygrass (Phalaris arundinacea); European birch (Betula pendula); and False brome
(Brachypodium sylvaticum).
No federal or state Endangered Species Act (ESA)‐listed plant species or plant habitats have been
identified within the project area.
The project area includes 13 bodies of water: the Willamette River (and Mill Race), Canoe Canal
(Patterson Slough), Augusta Creek/Laurel Valley Creek, and several unnamed streams and roadside
ditches; eight of which are located within the City of Eugene limits and three of the waterways
connect/flow to waterways within City of Springfield limits.
Fourteen wetlands have been identified and delineated within the project area. Wetland delineation
reports for the project area are included as Exhibit E. A total of 11 wetlands have been located within
the City of Eugene (one of which is located in both the Cities of Eugene and Springfield). The remaining
three wetlands are located within the city limits of Springfield. The wetlands include emergent, shrub‐
scrub, and forested wetland types.
The proposed project will have temporary impacts on wetland and water resources within the project
site from the construction of temporary work bridges, the removal of the existing decommissioned
bridge and existing temporary detour bridge, plus associated construction activities such as clearing,
grading, excavation, and the construction and use of staging areas, and hauling routes.
Construction activities will require in‐water work. Direct impacts associated with in‐water work include
construction of temporary work/containment bridges, removal of existing piers and construction of the
proposed bridge piers, which involves site preparation, pile driving, dewatering and isolation, and re‐
watering once work is complete.
Approximately 0.04 acre of wetlands and 1.18 acres of waters will be temporarily disturbed during
construction activities. Temporary disturbances will include vegetation removal, excavation/fill
associated with temporary work bridges, removal of the decommissioned bridge, and creation and use
of construction staging areas. Approximately 0.02 acre of wetlands and 0.55 acres of waters will be
permanently impacted with implementation of the proposed Project. Wetland impacts described herein
are based on the entire project (Phase I and Phase II).
After the project is completed disturbed wetland vegetation and hydrology will be reestablished.
Wetlands temporarily impacted during construction (including areas occupied by temporary work
bridges, staging areas, and the decommissioned and detour bridge locations) will be restored to pre‐
existing conditions following the completion of work. It is anticipated the wetlands will return to a
functioning state within five years. Vegetation plantings associated with site restoration will increase
the number of native plant and tree seed banks, which could improve localized genetic diversity and
minimize distances necessary for plant pollination. The project may eradicate some noxious weeds
through vegetative and seed bank removal.
Attachment 1-47
Exhibit 2-3
To minimize the impacts to vegetation and habitat during construction and operational activities the
project will continue coordination with resource agencies (federal, state, and local) and implement OTIA
III EPS, obtain regulatory permits (Oregon Department of State Lands [DSL] Removal‐Fill and USACE
Section 404), provide site restoration and compensatory mitigation, and identify additional
opportunities to minimize disturbances to vegetation and habitat. The Applicant will coordinate with
Oregon Department of Fish and Wildlife (ODFW) through the final design process to identify
opportunities to minimize habitat disturbance. To avoid and minimize impacts, additional mitigation
measures will be implemented to reduce the extent of direct and indirect impacts to habitat. These
include:
▪ Minimize effects to natural stream and floodplain by keeping the work area within the smallest
footprint needed.
▪ Prepare and implement a plan to prevent construction debris from dropping into the Willamette
River and to remove materials that may drop with a minimum disturbance to aquatic habitat.
▪ Prepare site restoration plans for upland, wetland, and streambank areas to include native plant
species and noxious weed abatement techniques, and use large wood and rock as components of
streambed protection treatments.
▪ Flag boundaries of clearing limits and sensitive areas to be avoided during construction.
▪ Coordinate with WPRD, Eugene POS, and the CPC regarding sensitive areas in the Whilamut
Natural Area of Alton Baker Park, which should be avoided during construction.
▪ Restore and revegetate disturbed areas using native plant species and noxious weed abatement
techniques. Disturbed areas will be restored to the same or better condition than before
construction.
▪ Where practical, revegetate riparian areas beneath new bridges with native plants appropriate for
limited light conditions.
▪ Employ a five‐year monitoring and maintenance plan for site restoration areas.
▪ The Applicant will provide training for the contractor staff and construction inspectors regarding
sensitive species in the project area. If Northwestern pond turtles or other sensitive species are
encountered during construction, they will be relocated by qualified personnel to an appropriate
area outside of the project construction area.
▪ The contractor will implement the Noxious Weed Management Plan and clean vehicles and
equipment to prevent tracking and spread of noxious weed seeds.
The Applicant has entered into formal agreements with the WPRD and Eugene POS regarding the
mitigation and conservation measures that will be executed during and following construction. In
addition to the above noted mitigation measures, the Applicant proposes the following measures:
▪ Plant the area immediately west of I‐5 in the Whilamut Natural Area with native vegetation to
extend the riparian forest to the area between the Willamette River and the Canoe Canal.
▪ Remove invasive plant species from the riparian forest area immediately west of I‐5 and south of
the Canoe Canal.
▪
Attachment 1-48
Exhibit 2-4
▪ Plan and implement the above enhancement measures in coordination with Eugene POS and the
CPC for the Whilamut Natural Area. These areas will be monitored and maintained by the
Applicant for one year.
II. Fish
Two salmonid populations listed under the Endangered Species Act are documented as occurring within
the reach of the Willamette River that flows through the project area:
▪ Upper Willamette River spring Chinook (Oncorhynchus tshawytscha) and Critical Habitat –
federally threatened (FT)
▪ Columbia River bull trout (Salvelinus confluentus) Distinct Population Segment (DPS) and Critical
Habitat – FT
The Willamette River supports resident populations of numerous native and introduced species that are
not threatened or endangered. It supports two anadromous salmonids that are not listed or proposed
for listing within the project area. Specifically, it provides spawning and rearing habitat for fall Chinook
and a migration route for steelhead. Resident native fish that are likely to be present in the project area
include: Rainbow trout (O. mykiss); Cutthroat trout (O. clarkii); Sculpins (Cottus spp.); Leopard dace
(Rhinichthys flacatus); Longnose dace (Rhinichthys cataractae); Redside shiner (Richardsonius balteatus);
Northern pikeminnow (Ptychocheilus oregonensis); and Largescale sucker (Catostomus macrocheilus).
The width of the Willamette River varies from 600 feet to 800 feet in the vicinity of the bridge crossing.
Through the project area, the Willamette River is generally confined by a bedrock channel. Near the
existing bridges, the Willamette River consists of shallow riffle habitat. Along this reach of the
Willamette River, the ODFW designated in‐water work window is June 1 to October 31. This is the time
period when construction activities may occur within the active waterway.
North of the Willamette River, the Canoe Canal (Patterson Slough) begins upstream from the project
area through a culvert connected to the Willamette River and flows through the project area and
reconnects with the Willamette River about 2.5 miles downstream. The Canoe Canal is unlikely to
provide salmonid spawning habitat due to the lack of suitable spawning gravel, but likely serves as off‐
channel rearing habitat for steelhead and resident trout as well as Chinook salmon. This water body also
provides potential Oregon chub habitat.
In the southern portion of the project area there is a small, unnamed stream associated with Glenwood
Slough that flows to the Willamette River. It is generally low quality fish habitat and there is little cover
or riparian vegetation. This stream connects to the Willamette River through a culvert underneath
Franklin Boulevard that drops about one foot onto riprap with no pool at the outlet, which makes this
culvert a fish passage barrier. The stream provides no habitat for salmon, steelhead, or other
anadromous species; however, resident cutthroat trout have been observed in the stream.
Augusta Creek/Laurel Valley Creek is conveyed from the west under I‐5 through a box culvert near the
terminus of Judkins Road. This stream flows through a corrugated metal arch culvert and through a
culvert under the railroad grade to converge with the unnamed tributary (discussed above) upstream of
Attachment 1-49
Exhibit 2-5
the Franklin Boulevard culvert. Upstream of I‐5, Augusta Creek/Laurel Valley Creek is likely to provide
habitat for species such as sculpins (Cottus spp.) and resident cutthroat trout.
Construction activities will require in‐water work and are anticipated to require four in‐water work
periods. Temporary effects from in‐water work will include construction of temporary
work/containment bridges, construction or removal of piling/piers, which involves site preparation, pile
driving, dewatering and isolation, and rewatering once work is complete. Proposed in‐water work will
require work area isolation with the use of cofferdams or similar measures designed to isolate work
areas from the river. Work area isolation will require fish capture and release operations in the
Willamette River, which would affect both listed and non‐listed fish species. All fish capture and release
operations will be conducted by experienced biologists following guidelines established by ODFW and
National Marine Fisheries Service (NMFS).
There will be permanent direct effects to fish or aquatic resources, such as loss of habitat or habitat
alteration by the placement of piers within the ordinary high water (OHW) of the Willamette. The pier
placements would result in direct impacts to fish habitat. Although this would be a direct impact to fish
habitat within the Willamette River, it would represent a benefit when compared to the existing
conditions and the number of piers currently below the OHW and within wetlands (a total of 29 piers).
The proposed project will have a smaller footprint within the Willamette River, allowing increased
opportunities for fish and aquatic resources to utilize the project area.
No direct permanent impacts would occur to fish or aquatic resources from the loss of habitat or habitat
alteration over the Canoe Canal.
The proposed project during construction and when operational will not obstruct fish passage in the
Willamette River, Canoe Canal (Patterson Slough), or adjacent unnamed waterways where resident fish
are present. The proposed project will not have a direct impact to existing hydraulic and fluvial
conditions that would cause changes to the aquatic environment.
The project does have the potential to impact fish and wildlife species during construction activities. To
avoid fish and wildlife species and minimize temporary impacts from construction activities, all
applicable OTIA III State Bridge Delivery Program EPS will be implemented to reduce the extent of direct
and indirect impacts to fish and wildlife species. These include (but are not limited to):
▪ Fish avoidance, including in‐water work timing
▪ Cessation of work under high flow conditions
▪ Fish screens for water in‐takes or diversions
▪ Providing for fish passage during and after construction and preparation of a Fish Passage Plan for
submittal and approval from ODFW
▪ Isolation of the work area and release of fish species captured during isolation
▪ Maintain existing and re‐establish connectivity between aquatic habitats for fish movement
▪ Follow the terms and conditions of ODOT’s most recent Drilling Programmatic Biological Opinion
Attachment 1-50
Exhibit 2-6
In addition to the measures outlined in the OTIA III State Bridge Delivery Program EPS, the following
measures will be implemented to further avoid or minimize the impacts of the project:
▪ The contractor will minimize lighting during construction to only the areas necessary for safety,
security, and operations. The Applicant will encourage directional lighting for areas where
lighting is required for construction, safety, or security, to minimize intrusion into the surrounding
natural area.
III. Wildlife
A species list provided by Oregon Natural Heritage Information Center (ORNHIC) indicated that there are
no federal‐ or state‐listed ESA terrestrial wildlife species known to reside within the project area. There
are reports of sensitive or species of concern terrestrial wildlife within two miles of the project area;
however there is habitat that would support only one of these sensitive species in the project area (i.e.,
the northwestern pond turtle).
The project area provides potential habitat for bird species protected by the Migratory Bird Treaty Act
(MBTA): Cliff swallows (Hirundo pyrrhonota). These birds may use the existing bridges for nesting
locations, although none were present during field investigations.
Human‐tolerant wildlife species such as raccoons (Procyon lotor), coyote (Canis latrans), and various
perching birds occur within the project area. Beavers (Castor canadensis), bats (Myotis spp.), osprey
(Pandion haliaetus), great horned owl (Bubo virginianus), western meadowlark (Sturnella neglecta),
western gray squirrel (Sciurus griseus), northwestern pond turtle (Actinemys marmorata), river otters
(Lutra canadensis), great blue heron (Ardea herodias), and raptors may also be present. The existing
bridges in the area may provide roosting habitat for bats such as the little brown bat (Myotis lucifugus),
big brown bat (Eptesicus fuscus), and yuma myotis (Myotis yumanensis). Townsend’s big‐eared bats
(Corynorhinus townsendii) are known to occur on the I‐5 bridge over the McKenzie River located about
four miles north of the project area.
Northwestern pond turtles (Actinemys marmorata) have been reported in Canoe Canal within the
project area (ORNHIC, 2006). However, much of the Canoe Canal within the project area is a concrete
channel with steep banks and lack of suitable nesting habitat, which is likely to reduce the frequency of
pond turtle occurrence. The northwestern pond turtle also uses the Willamette River, isolated
ephemeral ponds adjacent to hiking trails within the project area, and upland habitat areas for nesting
and overwintering.
There is a great blue heron rookery (which may have become inactive) along the Canoe Canal located
about 800 feet east of the project area. Eugene POS and WPRD staff have noted the ephemeral ponds
located throughout the Whilamut Natural Area of Alton Baker Park provide habitat for amphibian
species. Western meadowlark nesting habitat has been documented in the vicinity of the meadow
immediately northwest of the project area.
For wildlife, temporary effects from vegetation/habitat removal would result in fragmentation of habitat
during soil disturbance activities and would displace species and may potentially kill some individuals
(including amphibians, reptiles, birds, and mammals) that are not able to move out of the area.
Although already partially impeded by existing development, wildlife passage through riparian, wetland,
and upland habitat areas would be further impeded with the clearing of vegetation and use of heavy
Attachment 1-51
Attachment 1-52
Exhibit 2-7
equipment (i.e., movement and use of equipment on haul roads through Whilamut Natural Area, and
equipment use along the banks of the Willamette River, and wetland areas located within the project
area), which provides perching and nesting habitat for birds and cover for other animals.
Construction of the project would result in permanent vegetation removal, thereby removing habitat for
local wildlife species. The ground surface below the bridge spans should receive enough light to allow
existing and replanted native vegetation to grow maintaining habitat similar to existing conditions.
Although there would be some changes to existing habitats onsite, there would be no permanent
impacts to wildlife movement because there is enough clearance at the site to allow continued wildlife
movement beneath the bridges.
Temporary effects on resident wildlife may be caused by noise associated with construction activities
and construction equipment moving to and from the project site. Noise levels from operation of
machinery during certain construction activities would cause temporary, short‐term, or localized noise
increases. There would be no impacts anticipated to wildlife from increased noise levels during
operational activities.
Construction lighting used at night may disturb wildlife, particularly nocturnal birds and mammals.
Impacts from lighting could extend outside of the established staging and construction limits; however,
the light would be more diffuse moving away from the construction limits and would affect the areas
immediately adjacent to the freeway corridor, Franklin Boulevard, and Union Pacific Railroad (UPRR)
tracks. Visual changes that would result from the project would not affect wildlife.
The project does have the potential to impact fish and wildlife species during construction activities. To
avoid fish and wildlife species and minimize temporary impacts from construction activities, all
applicable OTIA III State Bridge Delivery Program EPS will be implemented to reduce the extent of direct
and indirect impacts to fish and wildlife species. These include (but are not limited to):
▪ Wildlife avoidance to minimize injury and death to wildlife species by incorporating timing
restrictions under the MBTA, including no removal of trees being used for nesting during the
breeding season.
▪ Apply exclusionary methods to prevent nesting activities before March 15.
▪ Maintain existing and re‐establish connectivity between upland habitats for wildlife movement.
▪ Incorporate bat habitat into the design of the new bridge.
In addition to the measures outlined in the OTIA III State Bridge Delivery Program EPS, the following
measures will be implemented to further avoid or minimize the impacts of the project:
▪ ODOT will coordinate with WPRD during design and construction regarding the status of the great
blue heron rookery located in the Whilamut Natural Area of Alton Baker Park. If the rookery is
active, pile driving will be restricted during the great blue heron nesting period (February 1 – May
31).
▪ The contractor will minimize lighting during construction to only the areas necessary for safety,
security, and operations. ODOT will encourage directional lighting for areas where lighting is
required for construction, safety, or security, to minimize intrusion into the surrounding natural
area.
