The Oregon Department of Transportation (ODOT) ("the Applicant") requests approval for Phase II construction of the Interstate 5 (1-5) Willamette River Bridge Project (Project, Proposal). The Project replaces the decommissioned Willamette River and Canoe Canal bridges and detour bridges with new bridges. The existing 1-5 Willamette River Bridge is located within both the cities . of Eugene and Springfield, with the decommissioned bridge center line constituting the boundary line separating the two cities. The Applicant proposes to locate the replacement bridge in essentially the same location as the existing 1-5 bridge. . Demonstration of compliance with applicable land use regulations of both jurisdictions is required. The Project site is comprised of state-owned right-of-way (ROW), state-owned property, railroad ROW, and city-owned property. The majority of the Project site is within state-owned ROW associated with 1-5, the Willamette River corridor, and Franklin Boulevard. Parcels within the Project site (discussed below) and within Eugene and Springfield jurisdiction are identified in Table 2-1. Within Eugene jurisdiction, temporary and permanent Phase II work is proposed on three parcels; Tax Lot No. 500 (Map No. 17-03-32-11), Tax Lot No. 800 (Map No. 17-03-33-14), and Tax Lot No. 100 (Map No. 17-03-33-41). Temporary or permanent improvements are not proposed on any of the remaining parcels identified in Table 2-1 within Eugene jurisdiction. These parcels are included for reference purposes because they will be utilized for construction access during the Project. Within Springfield jurisdiction, temporary and permanent Phase II work is proposed on three parcels; Tax Lot No. 101 (Map No. 17-03-33-41) and Tax Lot No's. 100 and 2600 (Map No. 17-03- 33-44). Temporary or permanent improvements are not proposed on the remaining parcel identified in table 2-.1 within Springfield jurisdiction. This parcel is included for reference purposes because it will be utilized for construction access during the Project. Table 2-1.

REVIEW (SPR). & FLOODPLAIN OVERLAY DISTRICT DEVELOPMENT (FP) APPLICATION The Proposal complies with all applicable Springfield Development Code (SDC) criteria listed in SDC 3.3-325, SDC 5.9-120, SDC 5.17-125, and SDC 3.3-420 and the submittal requirements listed on the Type III Willamett'e Greenway Overlay District Development, the Type III Discretionary Use, the Type II Site Plan Review,. and the Type I Floodplain Overlay District Development forms. The attached materials and enclosed findings demonstrate that the proposal is also consistent with applicable policies contained. in the Metro Plan and other relevant refinement plans. 2.2 Purpose and Need The purpose of the Project is to improve safety and maintain connectivity and mobility for all users of 1-5 over the Willamette River in the Eugene/Springfield Metropolitan Area. 1-5 is a major . transportation artery and the only freeway that traverses the entire length of the west coast from Mexico to Canada. Regional economies depend on the reliable use of it in the Eugene/Springfield area. The Project replaces the decommissioned Willamette River and Canoe Canal bridges and temporary detour bridges with permanent bridges to accommodate current and future traffic volumes. The project proposes two new bridges that will carry traffic in one direction each, northbound (NB) and southbound (SB). The Project is part of the Oregon Transportation Investment Act (OTIA) III State Bridge Delivery Program, which involves the repair and replacement of more than 300 bridges statewide over a ten year period. The Project is the largest in the $1.3 billion OTIA III Program. The current estimated completion date for the Project is December 12, 2012. 2.3 Summary of Proposal The proposed Project consists of the following main components: . Demolition of the decommissioned Willamette River Bridge, Canoe Canal Bridge, and detour bridges (salvaged portions of the bridges will be recycled or reused as much as feasible); " Construction of replacement bridges; " Reconstruction of the roadway near the bridges including the Franklin Blvd. on- and off- ramps; and . Construction of park bicycle and pedestrian path improvements to preserve and enhanc~ . public access along the river: -g. > The new bridges will be constructed in essentially the same location as the existing bridges; . (1) including relatively minor shifts of alignment, as well as minor changes to the Franklin Boulevar~ ramps. The new bridges will be designed with enough width to eventually carry up to six lane~f 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 eacho direction, matching the current 1-5 configuration in this area. en = = "" ro (T) - - "" .E .- .0 U :> C) en ro .~ Scheduling, construction, and permitting for the Project is occurring in two phases (Phase I and Phase II) to allow for adequate time to finalize project components including final design of the replacement bridges, final design of compensatory mitigation and site restoration plans (including final landscaping plans), final design of negotiated park improvements, and final stormwater design. .CMGS FINAL SUBMITTAL I October 22, 2009 4 1-5 WILLAMETIE RIVER BRIDGE PROJECT - PHASE II WILLAMETIE GREENWAY OVERLAY DISTRICT DEVELOPMENT (WG), DISCRETIONARY USE (DU), SITE PLAN REVIEW (SPR). & FLOODPLAIN OVERLAY DISTRICT DEVELOPMENT (FP) APPLICATION On February 18,2009, the Springfield Planning Commission granted Willamette Greenway Overlay District Development and Discretionary Use approvals of the Applicant's request to commence Phase I work, which includes temporary improvements within city-owned property and , permanent improvements within state-owned ROW.

SITE PLAN REVIEW (SPR), & FLOODPLAIN OVERLAY DISTRICT DEVELOPMENT (FP) APPLICATION 3.0 PROJECT BACKGROUND 3.1 Project Origin In 2002, during an inspection of the existing 1-5 Willamette River Bridge, it was found to have major structural problems that threatened the stability and safety of the bridge, including cracks in the supporting structures. I Based on the inspection analysis, weight limits were placed on the. bridge that required a 200-mile detour for heavy haul trucks. To eliminate the 200-mile detour for heavy haul trucks and improve traffic mobility, a temporary detour bridge was built in 2004 and the existing Willamette River and Canoe Canal bridges were taken. ouf of service (decommissioned). The detour bridges over the Willamette River and Canoe Canal carry both the NB and SB lanes on a single bridge. All traffic is now using' the temporary detour bridge. The detour bridge does not meet current seismic standards and the construction methods used to build the bridge only met environmental requirements as they apply to temporary, not permanent, bridges. The detour bridge has a design life of approximately 10 years. The decommissioned Willamette River Bridge (constructed in 1962) cannot feasibly be repaired or widened to accommodate the traffic flow and vehicle capacity demands that are projected 20 years . in the future. ODOT estimates that it would cost roughly $50 million to repair the decommissioned bridge to keep it in service for 20 more years. Those repairs would not widen . the bridge. The decommissioned bridge also does not meet current design standards. It was designed using bridge standards that are no longer appropriate for the size of longer and heavier, modern freight trucks. In addition, the bridge has substandard shoulders that do not provide enough room for disabled vehicles to move completely out of the travellan~s, creating a safety problem. 3.2 Budget and Funding Source I The I-S Willamette River Bridge project is part of the Oregon Transportation OTIA III State Bridge Delivery Program, which involves the repair and replacement of more than 300 bridges statewide over a 10 year period. The 1-5 Willamette River Bridge project is the largest in the $1.3 billion OTlA III program. The project is funded at $180 million, which includes preliminary engineering and design, ROW acquisition (if needed), demolition, road work, structures, ties to the existing transportation system, and all construction and inspection. Of the overall budget, approximately $70 million is designated just for the bridge structures crossing the river, railroad, and Fra~klin Boulevard, and Canoe Canal. This includes approximately $10 million designated for additional bridge aesthetics. The Safe, Accountable, Flexible, Efficient, Transportation Equity Act: A Lega~y for Users, a federal transportation funding package, will provide $30 million for this Project supplementing the $150 million from state sources. The OTlA III program emphasizes using local subcontractors and material suppliers; therefore, a substantial portion of the project cost is expected to be spent in the Eugene/Springfield area over a four year period. Date Received: I The inspe.ction resulted in a sufficiency rating of 20 o~ a 100 point scale. A bridge qualifie~ for re~C;tnkJ f,QOOg from the Federal Highway Bridge Replacement and Rehabilitation Funding Program if it has a sufficiency rating below 50.

The exception was adopted to Metro Plan text, Policy No. 13, Chapter III, Section D.2 The detour bridge is located entirely within the jurisdictional boundaries of the City of Springfield. In 2008, Lane County and the Cities of Eugene and Springfield and Lane County approved a Metro Plan amendment and an exception to Goal 15 authorizing the construction of the permanent replacement bridges and removal of the decommissioned and detour bridges. The exception was adopted to Metro Plan text, Policy No. II, Chapter II.. Section D.3 The Eugene ordinance also amended the Willakenzie Area Plan text for portions of paragraph one in the Willamette Greenway section to provide an exception for, U[r]eplacement or expansion of the 1-5 Willamette River Bridge and its approaches.'" On December 2, 2008, the Applicant requested concurrent Willamette.Greenway Overlay District Development and Discretionary Use approvals by the City of Springfield for Phase I of the Project including: temporary construction work such as staging areas, work bridges and roads; bicycle path relocation; permanent bridge substructures; Franklin Blvd. southbound on-ramp work; utilities; and bridge demolition. Approvals for Site Plan Review and Floodplain Overlay Distri~t Development were subsequently submitted to the City of Springfield. On February 18,2009, the Springfield Planning Commission granted Willamette Greenway Overlay District Development and Discretionary Use approvals of the Applicant's request. On April 2S, 2009 the City of Springfield granted Site Plan Review approval and on April 14, 2009 the City of Springfield granted Floodplain Overlay District Development approval for Phase I work. On April 25, 2009, a development agreement for Phase I work was executed between the Applicant and the City of Springfield, which contains the conditions of approval and additional requirements.s The development agreement is included as Appendix K.

SITE PLAN REVIEW (SPR), & FLOODPLAIN OVERLAY DISTRICT DEVELOPMENT (FP) APPLICATION 4.0 DETAILED PROJECT DESCRIPTION 4.1 Project Overview The 1-5 Willamette River Bridge Project proposes to replace both the decommissioned bridge and the.temporary detour bridge across the Willamette River, Franklin Boulevard, and the Union Pacific railroad tracks with two new parallel bridges (one NB and one SB). In addition, the existing bridges across the Canoe. Canal will be removed and replaced with new bridges. . The new crossing will be composed of two bridges over the Willamette River: one dedicated to carrying NB traffic and the other carrying SB traffic. The new bridges will be wider than the decommissioned bridge to accommodate additional travel lanes in the future, Additional travel lanes are not proposed as pari of this Project and the new bridge will be striped to match the existing travel lanes at both the north and south ends (I.e., two lanes in each direction). There would be. a slight shift in the alignment of 1-5; however the vast majority of all roadway and bridge improvements will remain within the existing ODOT ROW. The shift in alignment for the new Willamette River bridges will require the replacement of the decommissioned and temporary detour Canoe Canal bridges. Therefore, the existing 1-5 crossing of the Canoe Canal north 'of the Willamette River will also be replaced by a pair of new bridges. The new bridges will be constructed in the same general location as the existing bridges. As noted above, the new bridge location will require some minor shifts of alignment, as well as reconstruction of portions of the NB and SB on/off ramps to Franklin Boulevard. . The new bridges will be higher than the decommissioned-bridge to provide more clearance over Franklin Boulevard, which will provide flexibility to local jurisdictions for future improvements to the Franklin Boulevard corridor, as well as meet current vertical clearance requirements for state highways and railroads. Although there are no specific plans for future improvements to Franklin Boulevard, the proposed clearances would allow the addition of turning or through lanes, sidewalks or , bicycle/pedestrian paths, transit lanes, aesthetic treatments, or other improvements. For the purpose of this request, the new bridges over the Willamette River and the Canoe Canal will be considered the same facility. These bridges will meet current safety and design standards for all travel needs typical on this section of '.5. Traffic volumes will not change as a result of the proposed bridge replacement. No additional lanes or permanent speed zone changes are planned, although the new bridges will be designed to accommodate future traffic needs. I' . 4.2 Bridge Type The Project is the subject of a National Environmental Policy Act (NEPA) environmental assessment (EA) which identifies proposed measures that avoid, minimize, and/or mitigate environmental impacts. During the NEPA process, alternative conceptual bridge designs were developed that involved varying numbers of piers and footing locations. To minimize the bridges' footprints as much as feaSible within the Willamette River and its associated riparian area, the EA includes two footing options (Option A and Option B) for the replacement bridges. Both options include one footing location in the center of the river channel and two footing locations on or near the north and south banks of the river. The EA thereby established that no more than three bents would be constructed within or near the river channel.

The Applicant's design team conducted a comprehensive evaluation of possible alternatives. Seven main span alternatives were investigated. These alternatives were compared based on their performance on goals established by ODOT, th~ OTIA III State Bridge Delivery Program, and a Citizen Advisory Group (CAG) convened for the project. A concrete deck arch bridge type was ultimately selected based on its comparative impact, cost, aesthetic appeal, and ease of maintenance, among other factors. The concrete deck arch can be designed with a true or tied arch .support system. The Applicant initially envisioned a true arch, which is a demanding bridge type in terms of the lateral load to be resisted by foundation elements. Geotechnical analysis of the project area indicates that the foundation bedrock is adequate to support a true arch or tied arch system. A tied arch, however, is substantially more complex to construct requiring a longer duration of temporary impacts in the Willamette River. After reviewing the relative impact on the Willamette River from these two alternatives, as well as other differentiating factors, the Applicant selected the true arch system for the bridges. The se.lection of this design represents a significant reduction in. the duration of temporary impacts that will be placed below the Willamette River Ordinary High Water Mark (OHWM). 4.3 Bridge Design As noted above, the proposed replacement bridge will be constructed within the same general horizontal alignment as the existing decommissioned bridge, as illustrated on Sheet OS 1.0 Overall Site Plan (Exhibit C). From the 1-5 approach on either side of the river, the proposed bridge splits into separate NB and SB structures. The configuration of each structure is nearly identical. The proposed concrete deck arch structure over the Willamette River will span 806 feet and will be supported by four bents (piers, footings, sub-structures) founded on drilled shafts." Bent I is located approximately 200 feet north of the OHWM and Bent 2 is located approximately 100 feet north of the OHWM. Bent 3 is located near the center of the river channel, approximately 270 feet from the northern OHWM. Bent 4 is located at the southern OHWM boundary. Additional bents (Bents 5-10) are located south of the Willamette River and will support the structure as it spans approximately 1,000 feet over Franklin Boulevard and the Union Pacific Railroad ROW. Bent locations are illustrated in the enclosed Plan Set (Exhibit C). Bent locations were established and activities necessary to construct the sub-structure were authorized through the prior approved Phase I application ry.tG 08-4, SDR 08-7) and are included herein for context. The bents and arch ribs have been designed to maximize hydraulic efficiency and minimize effects to the aquatic environment. The proposed replacement bridges have a larger hydraulic opening than the existing decommissioned bridge and include a reduction of the bent area below the water surface elevation of the Willamette River. The reduction in hardened surfaces in the river channel will improve flow dynamics, minimize hydraulic drag and scour, and result in an overall Date Received: OCT 2 3 2009 · The Applicant notes that Bent I is the approach span connecting the 1-5 roadway to the deck arc.h stru. rture. \JrfgIP";:, :)Utlmlttal CMGS FINAL SUBMITTAL I October 22, 2009 12 1-5 WILLAMETTE RIVER BRiDGE PROJECT - PHASE II WILLAMETTE GREENWAY OVERLAY DISTRICT DEVELOPMENT 0NG), DISCRETIONARY USE (DU).

New bridge sub-structures will occupy 1.8% of the 709-foot active channel width and less than 4% of the streambed width: ' The proposed 1-5 replacement bridge over Canoe Canal is a single structure. I The superstructure will be supported by two driven steel pile end bents. The new alignment wilf shift slightly west of the existing alignment and will fully span the Canoe Canal OHWM elevation. ,. Demolition of the existing bridge (Phase I) and construction .of the new bridge will result in permanent removal of fill in the Willamette River. Where existing footings and columns are removed, the structures will be cut to at least three feet below the substrate surface, and the holes in the streambed will be filled with clean, native substrates that match the surrounding streambed materials. In areas where the footings and columns are surrounded by bedrock, the structures will be cut flush with the bedrock substrate surface to minimize additional impacts from bedrock excavation. The Project will result in a net loss of structure and non-native fill below the Willamette River OHWM. Therefore, an increase in overall habitat fun.ction, and reduction in fish passage impediments is expected following completion of the Project. 4.4 Phase II Work 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 (VVG 08-4, SDR, 08-7), involves only: development of construction access routes and staging areas; removal of the decommissionea 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 1-5 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 m.eet 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 oVl!r the Willamette River (VVillamette River Bridge); arid several spans of cast-in-plac,e concrete box girders over Franklin Boulevard, UPRR, and the NB exit ramp from 1-5 to Franklin Boulevard (approach . pate Received: , Fish Passage Plan; Bridge 08329.

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 s.upported by three bents founded on drilled shafts. Bent locations were established through the prior approved Phase 1 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 profile view, but deeper perpendicular to their axis. This appearance reinforces their role. aesthetically as the supporting elements of the spans.'O. The new NB and SB bridges will be constructed in two stages over a four-year period. Stage I . (2009-20 II) 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 1-5 roadway. On the north side of the Willamette River, a single concrete girder span will connect the 1-5 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 1-5 to Franklin Boulevard, to connect the concrete deck arch bridge to the 1-5 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 e.nd bents. The new alig!1menf will shift slightly west of the existing alignment and will fully span the Canoe Canal. The proposed project ~i11 not affect hydraulics through the bridge opening. Demolitionof 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 20 II following the completion of the SB bridge. Once completed, the SB bridge will maintain both directions of traffic until the NB bridge is completed.

" 'I 1-5 NB Off-Ramp (NB Exit Ramp to Franklin Boul~vard) , The Proposal involves reconstruction of the NB Exit Ramp (off-ramp) to Franklin Boulevard. Reconstruction of the SB On-Ramp to 1-5 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 1-5 (approximately 1,900 feet). The reconstruction will consist of a single-lane ramp with a 16-foot travel lane.

The proposed bark trail is 8 feet wide. The trail is within Springfield and within the WG boundary. Stormwater Management The Proposal involves stormwater management facilities designed to treat pollutants from the roadway, bridge surfaces, and other impervious surfaces. The Project will construct 3.53 acres of net new impervious area at the bridge and Franklin Boulevard interchange. This additional impervious area will be treated with the existing 14.39 impervious acres, for a 17.92-acre impervious area. The Project site is naturally divided .into two hydrologic sections (north and south) by the Willamette River. The proposed storm sewer and stormwater management systems for the Project provide capture, conveyance, treatment and detention/retention of site runoff as required by the ODOT Stormwater Management Program and by DEQ, NMFS, and the City of Eugene and the City of Springfield stormwater regulations. The proposed system provides capture and conveyance of runoff and directs runoff into stormwater management facilities consisting of vegetated swales, filter strips, and bio-retention ponds, all with soil amendments. These facilities provide treatment of roadway, bridge, and path runoff, and address total maximum daily load (TMDl) constituents listed for the receiving waters. Proposed stormwater facilities are detailed in the Stormwater Management Report (Exhibit D) and illustrated on Sheets CO.2, CO.2A, C2.0-C2.6 Stormwater and Utilities Plan (Exhibit C). Proposed drainage facilities for the Willamette River Bridge are a combination of storm sewer and stormwater management facilities. North of the bridge, inlets located within the shoulders of the roadway are proposed to capture runoff from the.bridge and roadway. No deck drains are proposed on the Canoe Canal Bridge, and one deck drain is proposed on the Willamette River Bridge. Runoff from the bridges is conveyed in the shoulder and collected by the one deck drain on the Willamette River Bridge and the inlets located at the end of the bridges. In addition to the permanent stormwater facilities installed during the Project, a number of temporary storm sewer facilities will be installed during the staged construction of the roadway and bridge elements. Temporary storm facilities are indicated in the Applicant's Construction Site Management Plan (CSMP - Eugene only) and land Drainage and Alteration Permit (lDAP - , Springfield only) and are not shown on the attached Plan Set (Exhibit B). The temporary storm sewer facilities are designed to the 10-year storm event and will consist of inlets, pipes, scuppered barrier runs, and gutters hung on the bridges. In order to minimize the number of temporary installations, permanent facilities are installed where possible to serve the temporary conditions. Utilities The Proposal involves the relocation of site utilities. In the proposed design, storm sewer and stormwater management facilities are located to prevent conflicts with existing utilities where possible. However, in cases where conflicts are unavoidable, utilities will be relocated to alleviate conflicts. Utility relocations are illustrated on Sheets C2.0-C2.6 Stormwa1ff~ ~g~ ~~Q . .

A 16-inch gas line owned by Williams Gas will be relocated due to the construction of a stormwater pond between the NB and SB ramps. The gas main currently passes directly under the pond bottom, and will be relocated completely outside the stormwater pond. Construction of the stormwater pond will also require that facilities owned by Eugene Water and Electric Board (EWEB) be relocated. The EWEB facilities, a buried three phase electric line and a fiber optic line sharing the same trench, will be relocated by placing them adjacentto the existing facility alignment and in a deeper trench to maintain adequate cover. Additional facilities to be relocated as part of the Project include two EWEB water lines: a 16 inch waterline between the NB Off-ramp and UPRR tracks has been relocated to avoid construction of new bridge piers; and, a 24 inch waterline between the UPRR track and the Willamette River will be relocated to avoid stream restoration. In addition, a Qwest underground fiber optic cable located along the bike path between UPRR tracks and the Willamette River and a Comcast underground fiber optic cable located on the north side of Franklin Boulevard may be relocated as part of the Project. 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 LO.3-LO.3D, L3.0-L3.6 Landscape Plan (Exhibit C). Within ODOT ROW, site restoration consists of slope stabilization and erosi~n control through planting, seeding, and bioengineered stream bank 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 smilllareas 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: I 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 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 I-acre of stre~m .

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.WhilamutPassage 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. '-5 Median Sculpture(s) This item consists of sculptural art piece(s) located within the 1-5 median on the nor:th side of the Willamette River, between the Canoe Canal Bridge and the Willamette River Bridge. The proposed median sculpture(s) are located within ODOT ROWand mostly within Springfield; maximum length 420-feet, maximum height 3D-feet. and maximum width, 20-feet. Wi/lomette River and Canoe Canol 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 CanoeCanl Bridge will include a solid concrete railing. Enhancements to the railing may include color choices. railing, insets, and/or textures. Northbound Soundwa/l Moterials Material choices for the proposed NB soundwall may include. use of surface-mounted or applied durable materials.

Construction began in June 2009 and is proposed to continue through 2012. The Applicant requests approval for Phase II work described herein through December 12. 2012. Demolition of the existing bridges and construction of the new facilities will require four summers of in-water work (IWW). which is only allowed from April I to April 30 and June I to October 31. The proposed southbound bridge will be constructed while the existing detour bridge is in use. Due to the large Willamette River channel width, temporary work bridges are required during demolition and construction. As established in Phase I, The first temporary work bridge will be constructed during the 2009 IWW period. Two additional work/containment bridge configurations will be constructed during the 20 I 0 IWW period. Removal of the work/containment bridge configurations will occur during the 20 II and 2012 IWW periods.

Intensification of uses, changes in use or developments may be permitted after this date only when they are. consistent with the Willamette Greenway Statute, this Goal and [other standards]." . The Applicant has demonstrated that the Project is consistent with the Willahlette Greenway Statute and Goal 15 through an approved Metro Plan amendment, including an exception to Goal 15, by' Lane County and the Cities of Eugene and Springfield. IJ Regarding "other standards" SDC 3.3-300, Willamette River Greenway Permits, provides that: "SDC 3.3-305 Purpose:. The Willamette Greenway (WG) Overlay District is established to protect and preserve natural scenic, historic, and recreational qualities of lands along the Willamette River." (SDC 3.3-305) . "SDC 3.3-310 Applicability: The WG Overlay District applies to all lands which are within 150 feet of the ordinary low water line on the channel of the Willamette River, or are adjacent to the river and are publicly owned for park and recreation purposes." (SDC 3.3- 310) "SDC 3.3-320 Permitted and Discretionary Uses: Uses allowed in the WG Overly District are the same as those in the underlying zoning districts. Anv chan~e or intensification of use. or construction that has si~nificant visual imoact shall reauire Discretionarv Use Aooroval." (Emphasis added). Because the proposed project will have a "significant visual impact," the project requires Discretionary Use approval. . The Discretionary Use approval criteria are addressed below in Section 6.2. In addition to Discretionary Use criteria specified in Section 5.9-120, projects located in the Willamette Greenway Overlay District shall also meet the standards specified in Section 3.3-325. SDC 3.3-325 Greenway Setback: A Greenway Setback Line is established to protect, maintain, preserve and enhance the natural, scenic, historic and recreational qualities of the Willamette Greenway. Only water-dependant or water-related uses are permitted between the Willamette River and the Greenway Setback Line.

DISCRETIONARY USE (DU), SITE PLAN REVIEW (SPR), & FLOODPLAIN OVERLAY DISTRICT DEVELOPMENT (FP) APPLICATION In the context of the statewide coastal goals (Goals 16-19), the Oregon Land Conservation and Development Commission (LCDC) has determined that bridges and bridge approach ramps on . piles are water-related or water-dependant uses. However, bridges and bridge approach ramps on fill are not considered to be water-dependant or water-related uses. I. The Metro Plan's Willamette Greenway policies. require a goal exception to locate a non-water dependant transportation facility within the Greenway setback. IS In 2008, Lane County and the cities of Springfield and Eugene approved a Metro Plan amendment and an exception to Goal 15 authorizing the construction ofthe permanent replacement bridges on fill within the Willamette Greenway. . Phase II of the Project involves: construction of replacement Willamette River and Canoe Canal bridges; removal of the existing temporary detour bridge; removal of temporary work bridges; and, improvement and/or replacement of multi-use paths, interpretive signage, stormwater facilities, natural area restoration and associated landscaping and utility improvements. Temporary construction staging areas and access routes will be restored to pre-construction conditions at the completion of the project and will not require permanent fill. Construction of temporary work bridges and staging areas will require temporary fill, however all temporary fill will be removed prior to the completion of the project and the .affected areas will be restored to their pre- construction condition. Demolition of the existing bridge was permitted as part of Phase I and does not require fill. The existing network of multi-use paths and trails along the Willamette River are water-related uses. Based on these findings, the Project is allowed in the Greenway Setback. The City of Springfield has adopted Greenway setback lines for both the north and south side of the river that extend from the Springfield/Eugene jurisdictional boundary line (the 1-5 bridge centerline) eastward past the detour bridge. . On the north side, the setback extends northward well beyond the bank of the river and includes the Eastgate Woodlands. On the south side, it extends southward a short distance from the river bank. Established Greenway setback lines are shown on Sheet T 1.0 Cover (Exhibit C) and on Sheets LO.2-LO.2A, L2.0-L2.6 Site Plans (Exhibit C). These findings together with the site plans submitted herewith demonstrate that this criterion is satisfied. . 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 p.ossible. Existing lands devoted to recreation within the Project area include the Whilamut Natural Area of Alton Baker Park and the Eastgate Woodlands. Within the Project area, the North Bank Trail extends along the northern border of 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 located I. 1-5 Willamette River Bridge Project Land Use Approvals Memorandum. Bridge Delivery Partners.

As part of the Project, the Applicant proposes to conduct minor reconstruction and improvement of the path and 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). The Applicant has coordinated extensively with WPRD 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 detailed in the Phase I approval and incorporated by reference herein. Except for minor reconfiguration of bicycle and pedestrian paths, no new public recreation uses are proposed as part of this project. These activities have been carefully coordinated with the Whilamut Natural Area CPC and will have a negligible effect on adjacent properties during construction. The applicant notes that to the extent the Willamette River is used for recreational fishing and boating purposes, Phase II construction activities will improve river conditions overall. Specifically, th!l proposed bridges will each have two piers in the main channel of the river. By comparison, the decommissioned bridge has five piers in the water, and the detour bridge has six - a total of II piers. The net reduction of piers in the water will increase the hydraulic opening, improve fish passage, and reduce in-stream work and associated environmental impacts during the proposed construction as well as during future bridge maintenance. From both aesthetic and navigation safety perspectives, this project will provide improved recreational benefits to those using the river. These findings together with the Plan Set (Exhibit C) and documentation submitted herewith demonstrate that this criterion has been met to the greatest extent practicable. B. Adequate public access to the river shall be provided. Within the Project area, the North Bank Trail.extends along the northern border of 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. . As proposed and approved in the Applicant's Phase I applications, construction activities and staging locations have impacted the existing network of multi-use (bicycle and pedestrian) paths and walking/jogging trails extending along the north side of the Willamette River. In order to continue . to provide for public access along the river between the communities of Eugene and Springfield during Phase II construction, the Applicant will maintain all temporary paved and soft paths proposed in Phase I to route traffic around and through the Project site for the duration of . construction. At the conclusion of Phase II bridge construction activities, the paths will be .

The applicant's Phase I Proposal, as approved, also included construction of a reconfigured, temporary bicycle/pedestrian path along the south side of the Willamette River. Within the state- owned ROW on the south side of the Willamette River, the Proposal includes a new multi-use path along the north side of Franklin Boulevard (Millrace Ruins Path) and an improved South Bank Path along the south side of Franklin Boulevard, as illustrated on Sheet L2.4 Site Plan (Exhibit C). The new Millrace Ruins Path will extend east from the Knickerbocker Pedestrian Bridge, along the north side of Franklin Boulevard. Although the path is proposed to extend outside of the Project area, only the portion within the Project area is included in the Proposal. The proposed path is the subject of a pending Metro Plan Amendment application. I. The existing South Bank Path along the south side of Franklin Boulevard will be realigned and reconstructed. The path extends east from Knickerbocker Pedestrian Bridge and accesses the south side of Franklin Boulevard. Paths and trails will, to the maximum extent practicable, be kept opem, safe, and useable during Phase II construction. A continuous route across state-owned right of way for the bicycle/pedestrian pathways will be kept open and accessible at all times along the north side, and to the extent practicable, along the south side of the river during construction. Pedestrian and bicycle traffic will be detoured around the construction site work areas immediately adjacent 1-5 and along the Willamette River and rerouted on new temporary and permanent alignments. To minimize disruptions, the Applicant will implement a Traffic Control Plan (TCP) for paths and trails; will coordinate with WPRD on path and trail closures; and will provide advance public notice of path and trail closures. These findings together with the Plan Set and documentation submitted herewith demonstrate that this criterion has been met to the greatest extent practicable. C. Significant fish and wildlife habitats shall be protected. The Metro Plan Natural Assets and Constraints Working Paper identifies the Willamette River Greenway in Figure J I 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 (Sa/velinus confluentus) Distinct Population Segment (DPS) and ~ritical 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.

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. Toavoid 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. D. Identified scenic qualities and view-points shall be preserved. The proposed Project is located within ODOT's 1-5 right-of-way in essentially the same location as the decommissioned bridge. The decommissioned bridge is not considered a scenic resource. Upon completion, the Project will significantly reduce the amount of structures, specifically piers, within the Willamette River which will open up views of the river from surrounding vantage points (I.e. the views from Alton Baker Park and the Eastgate Woodlands) and the river itself. The new bridges will have one pier near the center of the Willamette River and one on or near the south bank of the river to support the bridge structures. By comparison, the deco!f1missioned bridge has five piers in the water, and the .detour bridge has six, for a total of II piers. The new bridges will provide a substantial net reduction in piers and visibility and vividness of the surrounding landforms and vegetation will be enhan.ced over the existing conditions. As such, the project will have a positive effect on scenic qualities and viewpoints. These findings together with the Plan Set and documentation submitted herewith demonstrate that this standard has been met to the greatest extent practicable. 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. Paths and trails within the Project site will, to the maximum extent practicable, be kept open, safe, and useable during construction.

The natural vegetative fringe along the river shall be enhanced and protected to the maximum extent practicable. To minimize impacts to riparian vegetation 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 (DSL Removal-Fill, USACE Section 404), provide site restoration and compensatory mitigation, and identify additional opportunities.to minimize disturbances and enhance restoration. To minimize the extent of direct and indirect impacts to riparian vegetation, additional mitigation measures will be. Proposed mitigation .measures are identified in Section 4 and the Phase I application, and incorporated by reference herein. The Applicant has entered into formal agreements with WPRD regarding mitigation and conservation measures that will be executed during and following construction. Additional landscape mitigation measures included in the Proposal consist of: removal of invasive plants; replanting with native understory plants in riparian areas near the project; planting native. vegetation to reestablish a riparian forest in other areas; and restoration of areas disturbed by the project to pre-construction conditions. Impacts to riparian areas during Project construction are unavoidable. The Project is designed to avoid and minimize impacts as much as feasible. Prior to completion of Phase II construction, landscape and open spaces areas will be replanted and/or restored to pre-construction conditions or better. The Project will result in a net increase of landscape areas, open space, and vegetation and will provide the maximum possible amount of landscape area and open space following completion, as illustrated on Sheets LO.3-LO.3D, L3.0-L3.6A Landscape Plan (Exhibit C). .

The Project does not involve aggregate extraction. The standard does not apply. 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. The Project site is located on land committed to an urban use. Statewide Planning Goal 15, Section K(2) defines "lands committed to urban use" in part. as "those lands upon which the economic, . developmental and locational.factors have, when considered together, made the use of the property for other then urban purposes inappropriate." The Project site is physically developed with an interstate highway which will 'be active in its present location for the foreseeable future. Under numerous interpretations of LCDC Goal 12 (Transportation), state highways are considered "urban uses." Multi-use pathways are also considered "urban uses" as they serve a transportation function. Accordingly, the. proposed Project is an "urban use", is on land "committed" to "urban uses", and can continue as an "urban use" through development of the replacement bridges and associated infrastructure. These findings together with the Plan Set and documentation submitted herewith demonstrate that this standard has been met to the greatest extent practicable.

Because Phase II simply permits the completion of Project construction as outlined in the applicant's Phase I submittal, reconsideration of the use here is in some respects redundant. Even so, the Applicant provides findings of fact demonstrating compliance with all applicable discretionary use standards for Phase II below. To the extent that the Phase I Discretionary Use approval serves as justification to approve this application request, said justification is incorporated herein by reference. SDC 5.9-120 Criteria: A Discretionary Use may be approved only ifthe 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: The Project is subject to Site Plan Review. The Applicant's Site Plan Review application, submitted . concurrently herewith, demonstrates that the proposal conforms to all applicable approval criteria specified in Section 5.17-125. A. The proposed use conforms with applicable: I. Provisions ofthe Metro Plan; Pages 111-0-4 and 5 of the Metro Plan set out the Willamette Greenway.policies. Many of these policies are directed to local governments rather than to individual property owners or to the use of individual properties. Of the remaining policies, only two (presented below in italics) are potentially relevant to the subject request: Policy 0.5: 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. This policy has limited applicability to this proposal. Technically speaking, the proposed project is new 'development' due to the magnitude and duration of construction activities necessary to carry out the work. However, in essence the project proposed to replace the existing decommissioned bridges with new bridges in roughly the same location. The new bridges will be slightly wider and built to modern construction and safety standards. The Project may correctly be categorized as 'replacement' rather than new 'development'. Demonstration that the proposed use is compatible with the natural, scenic, and environmental qualities of the Willamette River is found in the current use. Policy 0.11: The taking of an exception shall be required if a nonwater.-dependent transportation facility requires placing of fill within the WiIlamette River greenway setback. On July 21, 2008, the Springfield City Council, together with the City of Eugene and Lane County, adopted Ordinance No. 6227 amending the Metro Plan text including an exception to Goal 15 for the 1-5 Willamette Bridge Project.

DISTRICT DEVELOPMENT (FP) APPLICATION the Metro Plan for the "purposes of removing and replacing the decommissioned 1-5 bridge, the temporary detour bridge and the Canoe Canal bridge with two new parallei"bridges * * *." This exception was found to comply with the statutory requirements governing the Greenway. Ordinance No. 6i27 specifically amended the text of Policy D.II of the Metro Plan as follows: "An exception to Statewide Planning Goal 15 Willamette River Greenway was approved for Oregon Department of Transportation (ODOT) for purposes of removing and replacing the decommissioned 1-5 bridge, the temporary detour bridge and the Canoe Canal bridge with two new parallel bridges (one southbound and one northbound) within the 1-5 right-of-way crossing the Wil/amette River and Canoe Canal and within the Wil/amette River Greenway Setback line. The exception authorizes construction and later removal of one or more temporary work bridges, demolition of the decommissioned 1-5 Wil/amette River Bridge, Canoe Canal Bridge, and detour bridges; construction of the two replacement bridges; reconstruction of the roadway approaches to the bridges (1-5 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 Wil/amette 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 1-5. This exception satisfies the criteria of Oregon Administrative Rule (OAR) 660-004-0022(6), Wil/amette Greenway, and the exception requirements of OAR 660-004-0020 Goal 2 Part lI(c) for a 'reasons' exception and pursuant to OAR 660-004-0015, is hereby adopted as an amendment to the Metro Plan text, Policy 0.11, Chapter III, Section D." The adopted Metro Plan text allows: I. The intensification of use and development proposed by the bridge replacement project and associated multi-use path and park facility improvements; 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. On September I, 2009, the joint planning commissiCln of Springfield, Eugene",and Lane County unanimously approved a proposed ordinance to amend the Metro Plan text including an exception to Goal 15 for the construction of a proposed bicycle/pedestrian structure (South Bank Viaduct) beneath the Willamette River 1-5 Bridges. The viaduct will allow the future development of a riverfront path on the south side of the Willamette River, connecting Eugene and Springfield through Glenwood. The proposed ordinance specifically amends the text of Policy D.II of the Metro Plan for the "construction of the of the bike path viaduct including the fill and removal necessary to build.the structure." The proposed Metro Plan amendment and Goal 15 exception is pending final action by the home jurisdiction, the City of Springfield. The proposed ordinance amends the text of Policy D.II of the Metro Plan as follows: .' "An exception to,Statewide Planning Goal 15 Wil/amette River Greenway was approved by the cities of Eugene and Springfield and by Lane County authorizing construction of a bike path viaduct beneath the 1-5 bridges, along the south bank of the Wil/amette River.

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; North of the Willamette River, Springfield has .designated the Whilamut Natural Area as a significant Goal 5 resource. On the south side of the river, Springfield has established 75 foot riparian setbacks along the Willamette River to comply with federal the Clean Water Act and. Endangered Species Act: The Metro Plan Natural Assets and Constraints Working Paper identifies the Willamette River Greenway in Figure J I 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 tshowytscha) and Critical Habitat- federally threatened (FT) . Columbia River bull trout (Sa/velinus 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.

The Applicanfs Riparian Area Protection Report (Exhibit F) addresses the proposed riparian area protection and restoration methods relative to the Project. The Project has been designed to minimize impacts to areas currently within the riparian protection area associated with the project site. The majority of impacts will occur in areas that are currently degraded, contain little vegetation, and are dominated by non-native vegetation. The short-term impacts to the riparian corridor, including tree removal and ground disturbance, .will be mitigated using the proposed methods described in the submittal materials. These methods will restore and improve riparian area functions by assisting the maintenance of temperature, channel stability, .f1ood storage and groundwater recharge, decreasing sedimentation, and increasing wildlife habitat by removing invasive species and increasing native vegetation. To minimize the impacts to riparian vegetation during construction and operational activities the project will continue coordination with resource agencies (federal, state, and local) and implement OTIA III EPS, comply with regulatory permits (DSL Removal-Fill, USACE Section 404), provide site restoration and compensatory mitigation, and identify additional opportunities to minimize disturbances. . The Appliq.nt proposes additional mitigation measures identified in the Phase I approval and incorporated by reference herein. The City of Springfield Local and National Wetlands Inventory (LWI) identifies wetlands within the project site associated with Canoe Canal. The Applicant has. conducted detailed wetland delineations of the project site, which are included as Exhibit E. As shown on Sheets LO:2-LO.2A, L2.0-L2.6 Site Plan (Exhibit C), Phase II development will result in permanent impacts to designated wetlands. The applicant will mitigate these permanent wetland impacts throlJgh the purchase of credits in an approved off-site wetland mitigation bank. The applicant has purchased. 0.05 credits at the West Eugene Wetland Mitigation Bank as compensatory mitigation for permanent wetland impacts. Compensatory mitigation for temporary and permanent waters impacts includes planting and establishment of a 1.907.acre riparian forest within the northwest quadrant of the river crossing and .I.026-acre of stream and associated riparian area restoration in the concrete lined 'unnamed tributary of the Willamette River (Waters 4) in the southwest quadrant of the river crossing. Additional waters mitigation will be accomplished by reducing the number of bent footings currently associated with the detour and decommissioned bridges within the Willamette River (0.027-acre net reduction in bent area). Wetland impacts described herein are based on the entire project (Phase I and Phase II). At Project completion, disturbed wetland vegetation and hydrology will be reestablished (for temporary impacts) or mitigated (for permanent impacts), as illustrated Sheets LO.3-LO.3D, L3.0-L3.6A Landscape Plan (Exhibit C). . , As illustrated on Sheets LO.2-LO.2A, L2.0-L2;6 Site Plan (Exhibit C) and Sheets CO.

Runoff from the path flows overland . and is infiltrated prior to reaching either Canoe Canal or the Willamette River. This path currently receives stormwater treatment from the combination of the existing vegetation and infiltration. The proposed path will be treated by overland flow and infiltration using the existing vegetation and ground surrounding the path, as illustrated on Sheets CO.2, CO.2A, C2.0-C2.6 Stormwater and Utilities Plan (Exhibit C). South of the Willaniette River runoff from the existing path flows overland to an unnamed tributary associated with Glenwood SI()ugh and then flows into the Willamette River. This path receives water quality treatment via sheet flow through existing vegetation. A segment of the path, from the existing Willamette River Bridge to the end of the proposed relocation, currently receives no stormwater treatment. Runoff from this' section of the path flows directly into either the concrete-lined channel associated with the unnamed tributary or into a path-side ditch and is conveyed to the Willamette River. . The proposed path will be treated via construction of a 5-foot vegetated filter strip, as illustrated on Sheets CO.2, CO.2A,.C2.0-C2.6 Stormwater and Utilities Plan (Exhibit C); Within the project site, the Eastgate Woodlands are primarily forested and contain extensive wooded areas. Trees are. also found within the ODOT 1-5 ROW. As described in the Applicant's Environmental Assessment (EA), the Project has been designed to minimize impacts to trees and wooded areas. The Project will not result in any tree removal within the Eastgate Woodlands. The Applicant proposes extensive tree preserlation and protection activities, as illustrated on Sheets LO.1. L 1.0-L 1.6, L1.9A-LI.9C Tree Preserlation and Removal Plan (Exhibit C), to preserle and protect wooded areas not affected by'the proposed construction activities. Furthermore, the Applicant's proposed restoration activities, as illustrated Sheets LO.3-LO.3D, L3.0-L3.6A Landscape Plan (Exhibit C), will enhance wooded areas and restore areas impacted by construction to pre- construction conditions following the completion of work. These findings together with the Plan Set (Exhibit C) and documentation submitted herewith demonstrate that this standard has been met to the greatest extent practicable. 4. Adequate public facilities and services are available, including but not limited to, utilities, streets, storm drainage facilities, sanitary sewer and other public infrastructure. The Project does not involve the extension of public utilities or expansion of existing storm drainage facilities.

As shown on Sheets LO.2-LO.2A, L2.0-L2:6 Site Plan (Exhibit q, Phase II development will result in permanent impacts to designated wetlands. The Applicant proposes to mitigate these permanent wetland impacts through the purchase of credits in an approved off-site wetland mitigation bank. Specifically, the Applicant has purchased O.OS credits at the West Eugene Wetland Mitigation Bank as compensatory mitigation for permanent wetland impacts. Compensatory mitigation for temporary and permanent waters impacts includes planting and establishment of a 1.907 -acre riparian forest within the northwest quadrant of the river crossing and 1.026-acre of stream and associated riparian area restoration in the concrete lined unnamed tributary of the Willamette River (Waters 4) in the..southwest quadrant of the river crossing. Additional waters. mitigation will be accomplished by reducing the number of bent footings currently associated with the detour and decommissioned bridges within the Willamette River (0.027-acre net reduction in bent area). Site restoration within the Project area is designed to restore all areas disturbed during construction of the Project. The objectives of site restoration for the Project are to prevent erosion, to provide stream bank stabilization, to improve water quality, to improve native plant species composition, to improve fish and wildlife habitat, and to provide aesthetically pleasing vegetation composition within key Project areas. All'wetlands temporarily impacted by'the Project will be restored and enhanced, as illustrated on SheetS'LO.3-LO.3D, L3.0-L3.6A Landscape Plan (Exhibit C). Metro Plan policies C.22, C.23 and C.24address noise and appropriate noise mitigation measures for the design of new highway facilities. For the Project, it is predicted that changes in noise levels will range from a reduction of I dBA to an increase of 3 dBA over existing conditions. Changes in noise levels are anticipated due to minor changes in roadway alignment, adjustments in noise shielding through construction of new soundwalls (discussed further below) and increases in traffic .

The January 2008 Environmental AssessmeMt concluded that no substantial noise level increases (i.e., an increase of 10 dBA over existing levels) would result from , the Project. These findings demonstrate that no noise mitigation measures, beyond those already proposed, are needed as part of this application request.. ~ . The Applicant notes that two soundwalls are identified in the original projeci: requirements and are defined within the Agency report titled 1-5 Willamette River Bridge Projea Bundle 220, Noise Technical Report, dated January 2008 (copy available on request). Within Springfield's jurisdictional boundary, the applicant proposes to construct a northbound soundwall on the north side of the Willamette River, as .illustrated on Shee~ LO.2-LO.2A, L2.0-L2.6 Site Plan (Exhibit C). The soundwall will mitigate noise impacts on residential development located in the adjacent An,derson Lane Subdivision. Policy C.30: Except as othelWise allowed according to Federal Eme~gency Management Agency (FEMA) regulations, development shall be prohibited in ~oodways if it coulq result in an increased ~ood level. The-~oodway is the channel of a river or other water course 0I1d the adjacent land area that must be reserved to discharge a om~-percent-chance ~ood in any given year. . -I The 1-5 Willamette River Bridge is located witliin a FEMA designated regulatory floodway and floodplain. Therefore, the design of the replacement bridge must satisfy the~regulations set forth. in the National Flood Insurance Program (NFIP). The NFIP requires that any m,odifications that cause a rise in the Base Flood Elevations (BFEs, which corresponds to water surface elevations associated with the II OO-year flood event) must be approved by FEMA. The proposed structure satisfies the requirements of the NFIP and will not cause a rise in BFEs; therefore FEMA approval is not required. The no-rise condition is also a requirement of ODOT for any bridge replacement. . 1 proJect. ' In planning the Project, two pier location scenarios were considered (Proposed Option A and Proposed Option B) as shown in the Environmental Assessment for the project. The Phase I construction approval. permitted the construction of bridge sub-structures (piers) which conform to Option A. For the Environmental Assessment (EA). the hydraulic conditions of the 1-5 Willamette River Bridge Project were analyzed using the U.S. Army Corp ofiEngineers' HEC-RAS . model: Natural, existing, and proposed conditions (with pier locations Options A and B) were modeled: Con'servative assumptions regarding pier size were used for this modeling. The Applicant has conducted detailed hydraulic analysis for the Project confirming that, at the conclusion of Phase" construction activities, the Project will result in no net rise of the base flood elevation. The hydraulic analysis is a component of the Applicant's Floodplain Overlay District Development application and included in the submittal as Section, 6.4. The FP application i~ subject to review and approval by the City of Springfield and is submitted concurrently herewith. Acting as the local authority to implement FEMA regulations, the City of Springfield's review oflthe Project for compliance with the development standards at SDC 3.3-420 will provide assurance that the above ., criterion is satisfied. .

River Corridors. and Waterwavs Element Policy 0.5: 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. . This policy has limited applicability to this proposal. Technically speaking, the Project is new 'development' due to the magnitude and duration of construction activities necessary to carry out the work. The Project is not a change of 'use'. In essence, the Project proposes to replace the existing decommissioned bridge and detour bridge with new bridges in roughly the same location. The new bridges will be slightly wider and built to modern construction and safety standards. The Project may correctly be categorized as 'replacement' rather than new 'development'. Demonstration that the proposed use is compatible with the natural, scenic, and environmental qualities ofthe Willamette River is found in the current use. Date Received: 17 SHR 2009-0000 I.

On September 1,2009, the joint planning commission of Springfield, Eugene, and Lane County unanimously approved a proposed ordinance to amend the Metro Plan text including an exception to Goal 15 for the construction of a proposed bicycle/pedestrian structure (South Bank' Viaduct) beneath the Willamette River 1-5 Bridges. The viaduct will allow the future development of a riverfront path on the south side of the Willamette River, connecting Eugene and Springfield . through Glenwood. The proposed ordinance specifically amends the text of Policy D.II of the Metro Plan for the "construction of the of the bike path viaduct including the fill and removal necessary to build the structure." The proposed Metro Plan amendment and Goal 15 exception is pending final action by the home jurisdiction, the City of Springfield. , The proposed ordinance amends the text of Policy D.II. of the Metro Plan as follows: "An exception to Statewide Planning Goal 15 Willamette River Greenway was approved by the cities of Eugene and Springfield and by Lane County authorizing construaion of a bike path viadua beneath the 1-5 bridges, along the south bank of the Willamette River. The exception authorizes construaion of the bike path viadua including the fill and removal offill necessary to build the struau,re.

Pursuant to OAR 660-004-0015, this exception is hereby adopted as an amendment to the Metro Plan text, Policy 0.11, Chapter III, Seaion D." As a whole the proposal is consistent with the applicable Willamette Greenway policies set out in .the Metro Plan. This criterion is satisfied. Environmental Desif'n Element Policy E4: Public and private facilities shall be designed and located in a manner that preserves and enhances desirable features of local and neighborhood areas. and promotes their sense of identity. The Applicant notes that public participation and involvement has occurred throughout the planning, design and development process in accordance with Statewide Planning Goal I and ODOT administrative rules. As part of the Project, ODOT established a Community Advisory Group (CAG) composed of representatives of local neighborhood associations, parks departments (Eugene and Willamalane), the Citizen Planning Committee for the Whilamut Natural Area, chambers of commerce, and the University of Oregon that has been involved in the development of the project with continued involvement during selection of the bridge type. its design, and construction. In addition to the aesthetic elements of the bridge itself, the Project also includes a number of riparian area, pedestrian and bicycle path, and alternative mode infrastructure enhancements as well as natural and historic restoration activities including but not limited to: . Restoration and enhancement of the unnamed tributary associated with Glenwood Slough on the south side of the Willamette River (Phase II) Development of a South Bank Interpretive Area including an informational kiosk (Phase II) * Permanent extensions of the multi-use paths. including the Canoe Canal Path, on the north and south sides of the river (Phase II) Date Received: OCT ? 3 2il09 CMGS FINAL SUBMITTAL I October 22, 2009 Orininal Submittal 58 I-S WILLAMETTE RIVER BRIDGE PROJECT - PHASE II, .

Extensive landscaping and riparian area restoration within th~ greenway (Phase II) In addition to the enhancements described generallY above, a subset of the CAG has developed on overall theme, identified as the "Whilamut Passage,":: intended to establish an enduring identity for the area surrounding the bridge. The theme uses different places, uses, images, and language to integrate and reflect aesthetic enhancements in the project. Subsequent to development of the Whilamut Passage theme, the Applicant has facilitated a sequence of design workshops to generate a palette of potential aesthetic enhancement opportunities. The aesthetic enhancements are listed in Section 4.4 and incorporated by reference herein. The Applicant is currently in the process of refining the list and identifying the artists, craftspeop,!e and subcontractors needed to create the enhancements. The proposed projects will preserve and enhance the existing features of the environment immediately surrounding the '-5 Bridg~. In addition, the Brjdg~ itself will preserve and enhance desirable features of the local area and prcilnote a sense of identity: These improvements, together with the Bridge, will.contribute to and promote the area's identity ':as a primary gateway between ,'Eugene and Springfield. , ' . , F. f 0: Protect and manage existing and future trdnsportation infrastructure. . \, ,: The 1-5 Willainette River Bridge Project replaces a structurally deficient bridge with tWo new permanent bridges built to accommodate anticipated future traffic volumes, freight loads and natural hazard events (e.g. floods, earthquakes, etc.), The project contributes to the long-term resiliency of the interstate transportation network ahd ensures local access to essential goods and services during an emergency. This bridge replacem.~nt reflects an effort to manage and protect the 1-5 corridor, an essential part of the region and state's existing transportation infrastructure. , . , P~licy F./4: Address the mobility and safety need~ of motorists, transportation users, bicyclists, pedestrians, and the needs of emergency vehicle~ when planning and constructing roadway system improvements. 1-5 across the Willamette River is an existing trarisportation facility identified in TransPlan and the Oregon Highway Plan (OHP). Because the originall.~5 bridge is structurally deficient and had to be decommissioned, a new permanent bridge is needed, to address the safety a(ld mobility needs of ~. , motorists and facilitate efficient movement of emergency vehicles between the north and south sections of Eugene and Springfield. The new permanent replacement bridges can and will be designed 'to meet applicable state and federal safety and mobility standards. The temporary detour bridge cannot accommodate the safety needs of motorists because it does n~t meet current seismic s~ndards and the construction methods used to build it only met environmental requirements as they applied to temporary, not permanent, structures. , In regard to the mobility and safety needs of bicyclists and pedestrians, construction activities and staging locations will impact the existing network of .lnulti-use (bicycle and pedestrian) paths , . extending along the north and south sides of the Willamette River. This Proposal involves a comprehensive program to reconstruct and improve paths and trails affected by the project to ensure that necessary and adequate public access will be provided along both sides of the Willamette River at the completion of the Project.

SITE PLAN REVIEW (SPR), & FLOODPLAIN OVERLAY DISTRICT DEVELOPMENT (FP) APPLICATION Paths and trails will, to the maximum extent practicable, be kept open, safe, and useable during construction. To minimize disruptions to paths and emergency access routes, the Applicant will implement a Traffic Control Plan (TCP); will coordinate with WPRDon path and trail closures; and will provide advance public notice of path and trail closures. Policy F.15: Motor vehicle level of service policy: a) Use motor vehicle level of service stondords to maintain acceptable and reliable performance on the roadway system. These standards shall be used for: (I) .Identifying capacity deficiencies on the roadway system. ' (2) Evaluating the impacts on roadways of amendments to tronsportation plans, acknowledged comprehensive plans and fand-use regulations, pursuant to the TPR (OAR 660-012-0060). . (3) Evaluating. development applications for consistency with. the/and-use regulations of the applicable local government jurisdiction. b) Acceptable and reliable performance is defined by the following levels of service under peak hour troffic conditions: LOS E within Eugene's Centrol Area Tronsportation Study (CATS) area and LOS D elsewhere. c) Performance standards from the OHP shall be applied on state facilities in the Eugene-Springfield metropolitan area, This Proposal is intended to implement the prior Metro Plan Amendment decision which ensures that mobility is maintained over the planning period. The 1-5 Willamette River replacement bridges will be striped to provide two travel lanes in each direction, consistent with current striping . patterns. The bridges will be built to accommodate future restriping to three travel lanes in each direction when the adjacent sections of 1-5 are widened to three lan.es in each direction. TransPlan projects 150 and 260 provide for the future widening of 1-5 from four to six travel lanes north and south of the Willamette River. Because the 1-5 Willamette River Bridge is already recognized in TransPlan, there is no need to amend the plan. These findings address the. consistency ofthe needed plan amendments with applicable Metro Plan requirements and land use regulations. Other applicable land use regulations are addressed in the findings contained herein, The 1999 Oregon Highway Plan (OHP) classifies 1-5 as an "interstate highway" - its highest category of state highway - and identifies it as a major freight route. As an interstate highway, 1-5 provides connections to major cities, regions of the state, and other states. Within the Eugene- Springfield metropolitan area, it also provides connections for regional"trips. As ODOT representatives testified during the Metro PI~n Amendment process, the bridge will be striped with two travel lanes to meet existing ODOT volume to capacity performance standards.. The additional travel lane will meet ODOT volume to capacity performance standards in the future. F.16: Promote or develop a regional. roadway system that meets the combined needs for travel through, within and outside the region. 1-5 is a state facility that serves both statewide and regional transportation needs as defined in the TPR. . Specifically, the highway meets the needs for movement of people and goods (I) b!'!twe~n Date Recelvea~ CMGS FINAL SUBMITTAL I October 22, 2009 XT 2 2 21]92 60 . _ ~ I ...... .'-.....;~".....I ~, , 1-5 WILLAMETTE RIVER BRIDGE PROJECT - PHASE II . .

As such, it is an integral element of the Eugene-Springfield metropolitan area's regional roadway system. Indeed, it is likely the principal arterial serving the combined. needs for travel through, within', and outside the region. Replacing the existing structurally deficient bridge with two new bridges promotes the maintenance and continuation of the regional roadway system serving the combined needs for travel through, within, and outside the region. F.29: Support reasonable and reliable travel times for freight/goods movement in the Eugene- II Springfield region.' . Connecting 1-5 north and south of the WiliametteRiver via a new, structurally safe bridge crossing is essential to ensuring that reasonable and reliable travel times for moving freight and goods in the region are maintained. Without the connection, tens of thousands of vehicles daily would be required to seek alternative means for crossing the river, clogging capacity and causing conge'stion and delay throughout Eugene and Springfield. Existing roadways lack sufficient capacity to accommodate the existing 49,000 daily vehicle trips ?r the 73,000 daily vehicle trips anticipated on the 1-5 Willamette River Bridge by 2030. . These findings together with the Plan Set (Exhibit C) and supporting documentation submitted herewith' demonstrate that the proposed Project is consistent with the Metro Plan.. B. Capacity' requirements of public an~ private facilities, including but not limited to, water and electricity; sariitary sewer and stormwater management facilities; and streets a'nd traffic safety controls shall not be exceeded and the public improvem~nts shall be available to serve the site at the time of development, unless oth:erwise provided for by this. Code and other applicable regulations. The Public Works Director .or a utility provider shall determine capacity issues. , Ji. , The proposed Project is needed to address significant structural,problems w.ith the existing 1-5 Bridge. The existing bridge was decommissioned in 2004 after ODOT found substantial structural problems including cracks in the supporting structures. Built in 1962, the existing bridge was designed using bridge standards that are no longer sufficient for the size of modern freight trucks. Replacement of the 1-5 Willamette River Bridge is needed to meet state and federal safety and. mobility policies and to ensure that future vehicle and freight capacity along the 1-5 corridor is not compromised. The overall goal of the Project is to replace the existing bridge over the Willamette River, Franklin Boulevard, UPRR tracks, 1-5 NB exit ~o Franklin Boulevard, and bicycle/pedestrian facilities such that freight mobility is unrestricted and! the Oregon economy is stim~lated. , .. I. With respect to capacity concerns at the local level, ~he City of Springfield will be impacted primarily by traffic control and mobility constraints during construction of th~ Project. Specifically, periodic closure to Franklin Boulevard will occasionally eliminate all public and private transportation movements between Springfield and Eugene through the project area. Said closures will be needed to facHitate the deconstruction of the, existing bridge spans and movement of equipment into and out of the area. It is assumed at this time that only short-term closures will be needed on Franklin Boulevard, the NB off-ramp to Franklin Boulevard, and SB on-ljUJIjl, tool-5.

The NB off- ramp and SB on~ramp is a partial interchange serving to connect 1-5 traffic south of the.Willamette. River to and from Franklin Boulevard west of 1-5. Access for all other movementS can be served by the full movement interchange at Glenwo()d Bo.ulevard.. The Franklin and Glenwood ramps are spaced about 1,200 feet apart, and are connected with a continuous auxiliary lane in each direction. Based on movement capabilities and the limited distance between interchanges, the Glenwood interchange is a functional alternate .route during construction. The Project does not involve a Variance request or proposed uses "that would generate 500 or more vehicle trips per day, as specified in SDC 4.2~ I 05 A(4.)(a.) and (b.). The Applicant will implement a Traffic Management Plan (TMP) to provide the details behind the development of Traffic Control Plans (TCPs) and other measures that will be put in pla'ce for the construction, 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. Local roadway capacity will be impacted by the Project, but only on a periodic and temporary basis. Further, the TMP and TCPs will demonstrate that all adverse impacts on the local transportation ne.twork will be mitigated to the extent possible through advance notice of the closures, signage and local detour routes around the construction area. ' In addition to the bridge facility, local bike and pedestrian capacity will be increased through this project. Specifically, permanent reconfigured multi-purpose paths are proposed on both the north and south sides of the river. These paths will remain open during the duration of construction and improve existing and/or increase alternative mode access in the vicinity of the 1-5 Bridge. Once operational, the Project will not generate additional use ofJacilities and will not result in an !. exceeded capacity of 1-5 or any other public facilities. These findings together with the Plan Set (Exhibit C) and supporting documentation submitted herewith demonstrate that this criterion is satisfied. . C. The proposed development shall comply with all applicable public and private design and construction standards contained in this Code and other applicable regulations. SDC 4.2-105 Public Streets No new streets are proposed and no existing local streets will be impacted by the proposed development. Judkins Road, a Lane County facility, was permanent closed as part of the Project. The Project will conform to the ODOT Highway Design Manual, 2003 (English) and AASHTO 2002 Roadside Design Guide. All construction plans and associated documents will be prepared in accordance with the ODOT Oregon Standard Specifications for Construction, 2008; and the ODOT Bridge Design and Drafting Manual (BOOM). Because all public automobile transportation facilities will be constructed within state-owned ROW, local street standards do not apply.

The ODOT Stormwater Management Initiative divides the state into nine climate zones for stormwater treatment. The WRB site is in climate zone 2, which requires 50 percent of the two-year, 24-hour dl!ration storm to be treated for water quality. For water quantity treatment, the ODOT 5tormwater Management Initiative guidelines providean exception for water quantity treatment if the dis.charge directly outfalls into a large body of water, in this case the Willamette. River, or it is shown by hydraulic calculations that the geomorphic channel conditions are not changed by the net effects of the increased runoff. The City of Springfield has adopted, in the interim, the stormwater management guidelines from the City of Portland eureau of Environmental Services and Washington County Clean Water Services. The City of Springfield accepts stormwater management plans to be designed using either guideline. The City of Springfield also uses 0.5 cfs as the threshold for water quantity flow control. The new ODOT and DEQ requirements for contributing drainage area will be followed fonhe amount of stormwater runoff to be treated. The new guidelines apply to stormwater flowing into the project from ODOT right-of-way that is hydraulically.connected to the project. The additional contributing drainage areas that are required to meet the new directive include 1-5 from the end of the defined project up to.the Glenwood overpass; Franklin Boulevard from the crest vertical curve just west of the Franklin Boulevard overpass bridge to the end of the bridge; and the 1-5 NB off- ramp from the intersection of Riverview Drive to the Eugene city limits. The Best Management Practices (BMPs) selected for stormwater management on this project include bios lopes, grassy swale with amended soils, bio-infiltration swales, and dry detention ponds. All of the BMPs selected provide a high effectiveness for the removal of sediments, nutrients, and heavy metals both dissolved and particulates; and provide moderate effectiveness for removal of hydrocarbons and polyaromatic hydrocarbons. Stormwater management facilities included in Phase II, including the location and the type of BMP's selected to meet the EPS, are discussed in the Stormwater Management Report (Exhibit D). In the northernmost 900 feet of the project, there is no increasEl in impervious area; therefore, only water quality is required to meet the EP5. Bioslopes on both the NB and SB lanes were chosen for these areas because of the limited right-of-way.. The northern 700 feet, up to and including the Canoe Canal Bridge, will utilize bio-infiltration swales to provide water quality a,nd ,quantity. The bio-infiltration swales will have an overflow system that will discharge into Canoe Canal. A bio-retention pond, in between the northbound off-ramp and southbound on-ramp, is not a required stormwater management facility, but was included as part the design to alleviate potential stormwwater impacts to the UPRR culvert. Phase II stormwater management improvements fall into three main categories: (I) mechanical systems, (2) BMP's (engineered vegetative systems), and (3) overland flow/filtration systems.

North of the river, in the Eastgate Woodlands, path reconfigurations will be treated by overland flow and infiltration using existing vegetation and soil adjacent to the path (Springfield). These findings together with the Plan Set and documentation submitted herewith demonstrate that this standard is met. SDC 4.3-115 Water Quality Protection The Willamette River is the receiving water for the Project area. The Willar;nette River in the vicinity ohhe Project is. listed on the DEQ 303(d) List (Section 303[d] ohhe CWA) of water bodies that do not meet water quality standards. The Willamette River is listed for temperature, arsenic, chlorophyll a, dioxin, dissolved oxygen, E. coli, fecal coliform, manganese, mercury, and iron. Phase II construction activities will include vegetation removal and. soil dist~rbance, which could lead to erosion and increased sedimentation to wetlands and waterways, resulting in water quality impacts. Additionally, there is the potential for releases of hazardous materials and wastes such as oil, grease, and fuels used for construction equipmef11: or releases of products (concrete, silicants, etc.) which, if entered wetlands or waterways, would result in decreased water quality. Phase II:' construction activities will require in-wate~ work. Direct impacts associated with in- water work include construction or removal of piers which involves site preparation, pile driving, dewatering and isolation, and rewatering once work is complete.

Increased turbidity associated with in-water work should be minimal because the new and temporary piers for the work bridges would be drilled or driven into bedrock. There may be a slight increase of turbidity during rewatering of the isolation area from pulling isolation structure(s). This slight increase would be expected to be within allowable limits, which is an increase of up to 10 percent over natural background turbidity 100 feet downstream of the fill point. Potential temporary impacts to water quality during construction will be mitigated through use of standard Best Management Practices (BMPs) and erosion control measures. These measures will follow the ODOT Erosion Control Manual (ODOT 2005) and Oregon Standard Specifications (ODOT 2008). The Applicant's Land Drainage and Alteration Permit (LDAP), detailing erosion and sediment control measures to be used during construction, was approved for Phase I. construction and the Applicant will gain approval for Phase II construction. A Pollution and Erosion Control Plan (PECP) will be implemented prior to construction by the Applicant's contractor to minimize or avoid project effects to water quality. The Project also adheres to the conditions of the CW A 40 I Water Quality Certification issued for the USACE Section 404 permit. These findings together with the Plan Set and documentation submitted herewith demonstrate that this standard is met. SDC 4.3-117 Natural Resource Protection Areas During Phase II construction, temporary and permanent impacts to site features including parks, open space, and natural resource protection areas are unavoidable. The uses proposed in Phase II are allowed in natural resource areas per SDC 4.3-117(E)(2) subsections (m),(n) and (0). In accordance with SDC 4.3-117(K), the proposed transportation facilities and structures will replace existing facilities and will be located within existing state-owned ROW to the greatest extent practicable. . North of the Willamette River, Springfield has designated the Whilamut Natural Area as a significant Goal 5 resource.

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 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. 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, the Applicant has implement a Fish Passage Plan (FPP) and all applicable OTIA III State Bridge Delivery Program EPS have been followed for Phase I and will continue during Phase II to reduce the extent of direct and indirect impacts to fish and wildlife species. To minimize the impacts to riparian vegetation 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 (DSL Removal-Fill, USACE Section 404), provide site restoration and compensatory mitigation, and identify additional opportunities to minimize disturbances. The applicant's Phase I Willamette Greenway Permit and Discretionary Use application sections Section 5.6, 5.7, and 5.8 propose additional mitigation measures which are incorporated herein by reference. Vegetation and Habitat 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 managed grass areas within the 1.5 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 (Pha/aris arundinacea); European birch (Betula pendufa); and False brome (Brachypodium'sy/vaticum).

Western meadowlark nesting habitat has been documented in the vicinity of the meadow immediately northwest of the project area. As shown on Sheets LO.2-LO.2A, L2.0-L2.6 Site Plan (Exhibit q, Phase II development will result in permanent impacts to designated wetlands. The Applicant proposes to mitigate these permanent wetland impacts through the purchase of credits in an approved off-site wetland mitigation bank Specifically. the Applicant has purchased 0.05 credits at the West Eugene Wetland Mitigation Bank as compensatory mitigation for permanent wetland impacts. Compensatory mitigation for temporary and permanent waters impacts includes planting and establishment of a 1.907-acre riparian forest within the northwest quadrant of the river crossing and 1.026-acre of stream and associated riparian area restoration in the concrete lined unnamed tributary of the Willamette River (Waters 4) in the southwest quadrant of the river crossing. Additional waters mitigation will be accomplished by reducing the number of bent footings currently associated with the detour and decommissioned bridges within the Willamette River (0.027-acre net reduction in bent area). Site restoration within the Project area is designed to restore all areas disturbed during construction of the Project. The objectives of site restoration for the Project are to prevent erosion, to provide streambank stabilization, to improve water quality, to improve native plant species composition. to improve fish and wildlife habitat, and to provide aesthetically pleasing vegetation composition within key Project areas. All wetlands temporarily impacted by the Project will be restored and enhanced, as illustrated on Sheets LO.3-LO.3D, L3.0-L3.6A Landscape Plan (Exhibit C). Water Bodies The project area includes 13 bodies of water: the Willamette River (and MillRace). 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. As noted above, the Applicant proposes restoration of the concrete lined unnamed tributary of the Willamette River (Waters 4) in the southwest quadrant of the river crossing. Additional waters mitigation will be accomplished by reducing the number of bent footings currently associated with the detour and decommissioned bridges within the Willamette River (0.027 -acre net reduction in bent area).

The remaining three wetlands are located within 'the city limits of Springfield. The wetlands;include emergent, shrub-scrub, and forested wetland types. The proposed Phase II activities will have impacts on wetland and water resources within the project site from the construction of the replacement Willamette River Bridges, the removal of the existing temporary .detour bridge and removal of the temporary work bridge, plus associated construction activities such as clearing, grading, excavation, and the construction and use of staging areas, and hauling routes. In addition, Phase II activities will include the restoration, reconstruction and associated improvements to landscaping, drainage features and multi-use pathways illustrated in the applicant's Site Plans. i . . . . l Approximately 0.03 acre of wetlands and 0.08 acre of waters will be tempor,arily disturbed during construction activities. Temporary disturbances will, include vegetation removal, excavation/fill associated with temporary work bridges, removal of the decommissioned brfidge, and creation and use of construction staging. areas. Approximately 0.04 acre of wetlands and 0.45 acre 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). 1;he Applicant proposes to mitigate these permanent wetland impacts through the purchase of credits in an approved off- site wetland mitigation bank. Specifically, the Applic~nt has purchased 0.05 credits at the West Eugene Wetland Mitigation Bank as compensatory mitigation for permanent ,Wetland impacts. .concurrence was received from DSL and USACE for compensatory migration to wetlands. At the conclusion of major construction activities, a~y wetland vegetation a~d hydrology disturbed during Phases I or II will .be reestablished. Wetlan~s temporarily impacted during construction (including areas occupied by temporary work bridge~, staging areas, and the decommissioned and detour btidge locations) will be restored to pre-existing conditions following the completion of work. I(is anticipated the wetlands will return to a functioning state within five years. Vegetation plantings"associated with site restoration will be made in accordance with SDC.4.3-11](M) and 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. Additional Mitigation Actiyities 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 (DSL Removal-Fill, USAd,E Section 404), provide site restoration and compensatory mitigation, and identify additional opportunities to minimize disturbances to vegetation and habitat: Th~ Applicant has conducted extensive. coordination with ODFW to minimize habitat disturbance and has obtained all required regulatory permits. To avoid ,and minimize impacts of vegetatio,n removal and replacerT]ent, in accordance. with SC 4.3-117(M), additional mitigation measures will be implemented to reduce the extent of direct and indirect impacts to habitat.

Phase I work was detailed in a prior approved Floodplain Overlay District Development application (SHR 2009-0000 I). . A. General Standards: I. Anchoring.' Ail new construction * ~, * subject to less than 18 inches of flood water during a 100 year flood shall be anchored to prevent floatation, collapse or lateral movement of the structure and shall be installed using methods and practices that minimize flood damage * * * . Phase II construction activities will involve the construction of the superstructure and decks. . associated with two new replacement bridges. All required bridge supports and anchors, including all proposed bents, were detailed; reviewed and approved as part of the applicant's Phase I application submittals (refer to City of Springfield Floodplain Overlay District Development permit SHR 2009-00001). No additional bridge supports ar;e needed or proposed as part of Phase II construction activities. In addition to the bridge construction activities proposed above, Phase II proposes the deconstruction and. removal of the existing temporary detour bridge and removal of the temporary work bridge (TWB). Because these structures will be removed from the f1oodplainlfloodway, the anchoring provisions do not apply. The applicant n?tes that removal of. these structures will improve hydraulic conditions through the elimination of piers within the channel. . Specifically, Phase II activities will increase the hydraulic opening, improve fish passage, and reduce in-stream work and associated environlT1ental impacts during th~ proposed construction as well as during future bridge maintenance. In addition to the activities described above, the applicant proposes multi-use path, interpretive signage, stormwater facilities, natural area restoration and associated landscaping and utility improvements as part of Phase II construction activities. The applicant notes that all permanent and multi-use path construction and any ancillary construction activities will be constructed using methods appropriate within a flood zone. However, the specific anchoring standards described above do not apply. These findings together with the Plan Set and supporting documentation submitted herewith demonstrate that this standard is satisfied. . 2:a. All new construction and substantial improvements shall be constructed with approved materials and utility equipment resistant to flood damage. Concrete and structural steel will be the primary coiistruction materials for the proposed bridge footings, anchorages and superstructure.

" The Applicant's Hydraulic and Scour.Analysis Report (Exhibit I) describes the structural components that will be constructed and installed to', resist anticipated hydrostatic and hydrodynamic loads as well as any effects of buoyancy (discussion regarding hydraulic design occurs on Pages 7 and 8 ofthe report). Specifically, the applicant proposed extensive anchoring as detailed and approved in Springfield Floodplain Permit SHR 2009-0000 I of both the temporary work bridge and the proposed bridge support structure. In addition, the design and shape of bridge itself, as well as those components of the structure built within the f1oodway, will further reduce structural susceptibility to flood damage. For example, the proposed concrete deck arch bridges will each have two piers in the main channel of the river. One pier is located at the center of the span, and one pier is located just inside ordinarY high water on the south bank of the river. The configuration of these piers and the arch ribs they support has been developed with consideration given to hydraulic efficiency.

As currently constructed, the existing infrastructure provides ingress and egress to the construction area for applicable non-motored and motored ordinary and emergency vehicles, In that the Applicant does not propose any new residential, commercial or industrial development, no new streets are proposed or required. These findings together with the Plan Set (Exhibit C) and supporting documentation submitted herewith demonstrate that this standard is satisfied. S.b. No street or surface of any new street shall be at an elevation of less than I foot below the base flood height. . No temporary Or permanent streets or street surfaces are proposed as part of Phase II construction activities. Therefore, this criterion does not apply. C. Floodways.' Located within areas of special flood hazard established in Section 3.3-41 OA. and B. are areas designated as f1oodways. Since the f100dway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply: I. Encroachments, including fill, new construction, substantial improvement, and other development is prohibited unless certification from an engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge. With the exception construction activities for the proposed Millrace Ruins Path, Phase II activities do not involve the construction of any new, substantial encroachments into the floodway; all coffer dams and footings associated with the temporary work bridge and new replacement bridge were permitted in Phase I. The applicant notes that the top of the temporary work bridge (TWB) is at elevation 437.4 feet. The bottom of the TWB is at elevation 433.4 feet. The TWB was built in stages and i~ anchored on the leadiflg edge of the piles by drilling rock anchors into the bedrock to 30,000 pounds to prevent up-lift. As outlined above, the City of Springfield required a "No-Rise" analysis for the TWB as part of the applicant's prior approved Floodplain Overlay District Development application. The analysis for the TWB showed a slight increase in water surface elevation during a I OO-year flood event while the TWB is in place (2009-2012). The City of Springfield reviewed the applicant's floodplain application and determined that th~ rise is acceptable for the duration of the project. Exhibit j, 1-5 Willamette River Bridge FEMA Cross Sections, illustrates the temporary effect on the 100-year base flood elevation. The Applicant's revised No-Rise Certification is included as Exhibit H. The analysis includes the proposed Millrace Ruins Path proposed within the Floodway. At the completion of Phase II, the proposed replacement bridges will improve hydraulic conditions through the elimination of piers within the channel. The proposed bridges will each have two piers in the main channel of the river. By comparison, the decommissioned bridge has five piers in the water, and the detour bridge has six - a total of II piers.
