The site is located on a portion of the McKenzie River that is hydrologically very dynamic with outstanding habitat for salmonids, pond turtles, and other ecologically significant species. In addition to possessing high quality wetlands and riparian environment, the site also houses groundwater wellfields that are important to the community's potable water supply. This Plan, therefore, highlights the natural and human context to guide the future of this special place. The Plan provides the City with a long-term VISIOn and management strategy for this environmentally sensitive area, while providing the community with an understanding of the property's ecological importance. An overriding goal of the Plan is to incorporate potential new uses for the site that does not impede the site's existing uses (e.g., groundwater wellfield operation and maintenance, and stormwater management) or natural function. The planning process began with Springfield City Council identifying planning goals for the project site and with the formation of Mayor's Task Force. The Task Force represents a broad base of user groups, interested and affected agencies, associations and property owners and has provided assistance in the planning effort. In the planning process, the consultant project team assessed the site's characteristics, features, opportunities, and constraints through site inspections and review of documents that refer, or are applicable to the subject site. The team used an overlay analysis method, which "stacks" existing natural features, sensitive areas, critical resources, and regulatory setback requirements to identify those areas that merit protection and those that have potential for site improvements. Based on this overlay analysis, the team divided the site into three areas. These areas are identified as: 1) unsuitable for physical improvement, 2) suitable for improvement, and 3) suitable for improvement with mitigation. The team also identified the potential regulatory requirements for the proposed uses and improvements as well as the regulatory agencies involved. Potential uses identified for the site include: ~ environmental education programs; ~ wetland mitigation, enhancement and banking; ~ storm water management; ~ wellfield production and maintenance; ~ multi-use path (southern portion of site); ~ wildlife viewing; and ~ walking/hiking. ES-l 2-5 I Proposed improvements to the site include: ~ vegetation restoration; ~ relocation of overhead utility lines; ~ trailheads; ~ interpretive signage; ~ kiosk; ~ small scale information center; ~ multi-use path; and, ~ soft surface, ADA-accessible conservation trails. ES-2 I I I I I I I I I I I I I I I I Based on these uses, the site's natural features and City Council's goals, the Plan outlines a series of site policies for the management of the site. The site policies are divided into three categories: ~ restoration improvements; ~ physical improvements; and ~ site management. Implementation of the plan requires a cooperative effort among city, local, state and federal agencies and organizations. A general implementation scope identifies three elements for implementation including: ~ management requirements, ~ project formation, and ~ program development. 2-6 I McKENZIE RIVER OXBOW NATURAL AREA MASTER PLAN Section One: Project Overview I I I I I I I I I I I I I I , ~ 2-7 I ~~ McKenzie River Oxbow Natural Area Master Plan PROJECT OVERVIEW I I I I I I I I I I I I I , I Section I of this document provides an overview of this plan's purpose and a summary of the planning process. This section also provides contextual information on the site as it relates to the McKenzie River, its watershed, subbasin, and adjacent land uses. A historic overview ofthe river's geomorphic activity is provided through aerial photographs dating back to 1944. PURPOSE The purpose of this Master Plan (Plan) is to assess and document environmental conditions and to determine opportunities for conservation, enhancement, and appropriate uses of a unique 85- acre tract of land. Weyerhaeuser Company donated this property to the City of Springfield in 1993. The site is identified on Lane County Assessor's Map No. 17-02- 30-00 Tax Lot No. 401 and Map No. 17-02-29-00, Tax Lot No.) It is located north of the Eugene- Springfield Highway (Highway 126), immediately east of 42nd Street. It should be noted that the total area of land reviewed as part of the site analysis (refer to Section 6) is approximately 105 acres. 42nd Street Project Site Hwy. 126 Weyerhaeuser Company MAP 1: VICINITY MAP Not to Scale This additional area includes the portion of McKenzie River within the project site, land immediately north of the site, land east of the wellfield and land on the east side of McKenzie River. This area was included to provide the project consultants, Satre Associates (Satre), with additional information on adjacent natural features and how those areas influence the ecological functions of the site. This Plan will provide the City with a long-term vision and management strategy for this environmentally sensitive tract of land, while providing the community with an understanding of the property's ecological importance. An overriding goal of the Plan is to incorporate potential new uses for the site with existing authorized uses of the site - - - ... - SATRE ASSOCIATES 1-1 June 12,2001 2-8 Project Overview I ~~ McKenzie River Oxbow Natural Area Master Plan (e.g., well field operation and maintenance and storm water management) in a manner that allows for public use of the site, but does not impede the site's existing uses or natural function.

The two programs, although separate, shared certain functions and were dependent on one another throughout the process. The Springfield City Council outlined key goals and interests for the site, which provides a framework for the site program and potential uses. These goals and interests are discussed in Section 2: City Goals and Mayor's Task Force. The formation of the Mayor's Task Force (Task Force) was necessary to assist with planning efforts.

Those reports are discussed in Section 4: Previous Land Use Documents. Based on the information gathered from those reports, site inspections and meetings with the Task Force, an Existing Conditions Report (Report) was prepared. The Report documents known data pertaining to soils, floodplains, wetlands, vegetation, habitat values, and other environmental factors; existing on-site utility facilities (i.e., groundwater wellheads and monitoring wells) and other constructed features; and applicable plans, documents, and planned improvements and actions that provide planning and regulatory context. The Report was used as a basis for a site analysis, which identifies potential environmental influences, regulatory influences, site opportunities and constraints for proposed site improvements. The City Council and Task Force reviewed a draft schematic design. This Plan is a product of the revised draft schematic plan reflecting input from the City and Task Force concerning the site program, site analysis and regulatory requirements for proposed site uses. Satre identified potential partnerships and cooperative agreements with agencies or organizations to help the City implement the plan, and to assist with long-term management of the site. The three interim reports prepared during the planning process (City Goals and Interests; Existing Conditions; and a Site Facilities Program) are incorporated into this Plan. SITE CONTEXT Source: McKenzie Watershed Council website, h1tP://WWW.polld.llet/-mwcl The project site is part of the McKenzie River watershed, which extends from the ridge of central Cascade Mountains to the floor of the Willamette Valley. The McKenzie watershed encompasses an area of land approximately 1,300 square miles in Lane and Linn counties within the larger Willamette River watershed, which is a component of the even larger Columbia River watershed. _. iii SATRE ASSOCIATES 1-3 June 12, 2001 2-10 Project Overview I J~ I !~' ~~ McKenzie River Oxbow Natural Area Master Plan A recent analysis of the watershed, the McKenzie River Subbasin Assessment, ecological assesses the McKenzie River floodplain's ecology, identifies conservation and restoration opportunities, and discusses the influence of upstream actions and processes. This assessment identifies 37 river reaches, which are defined by changes in geomorphology, land use, tributary junctions, and/or cultural features. The project site is identified as Reach #10 of the McKenzie River subbasin. The McKenzie subbasin includes large contiguous blocks of federal land, private land, and almost exclusively private ownership of the floodplain. Forestry is the dominant land use within the subbasin. In the sensitive lower subbasin floodplain area, commercial and residential development is dominant. ~rn - SATRE ASSOCIATES 1-4 June 12,2001 I I I I I I I I I I I I I I / ,/ I Eight families of fish with 23 species, some of which are listed by federal and state agencies as protected Threatened or Endangered species, are native to the McKenzie River subbasin including: Chinook salmon, rainbow trout, cutthroat trout, bull trout and mountain whitefish. Issues that affected the vitality of those species include: migration barriers, increase in water temperature due to loss of riparian vegetative cover, competition for food with non-native aquatic species and loss of rearing areas. Another aquatic species that greatly depends on the viability of the river's subbasin is the Western Pond Turtle. The Western Pond Turtle, which is identified as a Species of Concern by federal and state regulatory agencies, uses the riparian habitat of the McKenzie River and its ponded areas for nesting sites. Certain avian species (e.g., willow flycatcher, yellow- breasted chat and osprey) have been adversely affected by the loss of lowland riparian vegetation within the subbasin. Riparian vegetation and the habitat it provides is an important aspect of the McKenzie River ecosystem. The ecological function of the river's riparian area depends on riparian vegetation, ponded areas, wetlands and diverse aquatic and wildlife habitat. The McKenzie River has been referred to in previous planning studies as a "scenic resource of the highest value" and as "a major environmental recreational, cultural and aesthetic feature of the metropolitan area.,,1 Headwaters for the McKenzie River originate from springs at Clear Lake, high in the Cascade Range. The McKenzie River flows 90 miles through the valley, and drops five thousand feet in elevation as it flows through ancient forests, agricultural land, and small communities including: Nimrod, Vida, Leaburg and Walterville before merging with the Willamette River just north of Eugene. Main tributaries emptying into the McKenzie River include the Mohawk River, Gate Creek, and Quartz Creek. The river provides a variety of resources and recreational opportunities and is the sole .source of public drinking water for the City of Eugene, Oregon.

The project site is one of the few areas left where the river interacts dynamically with its floodplain and has a healthy system of side-channels, islands and ponds. The McKenzie River supports a diverse aquatic ecosystem. This ecosystem is affected by changes in flow regime, water temperature, turbidity and sediment, water quality, channel complexity, bank hardening, loss of riparian vegetation, and land use within the watershed. Project Site The project site covers approximately 85 acres abutting the Springfield city limits and Urban Growth Boundary (UGB), and WiIlamalane Park and Recreation District Boundary, but is within the Eugene-Springfield Metro Area General Plan (Metro Plan) boundary. The entire site is within the 100-year floodplain and a portion of the site, primarily along the westerly riverbank, is located within the floodway (see Map 2- Existing Conditions Map). Land south, west and northwest of the site is in the City's Heavy Industrial zoning district; property to the north and east across the main river channel, is zoned Rural Residential and in Lane County jurisdiction. The subject site is zoned Exclusive Farm Use by Lane County, but is designated Public Open Space on the Metro Plan diagram. The site is the only location within the Springfield metro area in public ownership along the McKenzie River within such a diverse natural setting. The McKenzie River within the project site boundaries is historically a geomorphically and hydrologically active area, with significant movement and braiding of river over time. The following historic photos of the portion of the McKenzie River in the project site depict substantial river c~annel migration. _I III SAfRE ASSOCIATES 1-5 June 12, 2001 2-12 ~~ I Project Overview McKenzie River Oxbow Natural Area Master Plan 1 4: ere does not appear to be a well defined channel. 1968: A geomorphic foundation of island can be seen.

The company's regional offices (for timberlands and regional administrative staff) are also located on this property. The project site and the Weyerhaeuser Company property are connected by Keizer Slough, which runs from the Weyerhaeuser site through the southerly portion of the site to the McKenzie River. Other businesses adjacent to the site include: Oregon Industrial Lumber Products Inc., located north of the site on the north side of Marcola Road; the Child Center located northeast of the site on the south side of Marcola Road; the Springfield School District 19 maintenance yard, Rainbow Water District's headquarters and water treatment facility located west of 42nd Street; and the Riverview Market northeast of the site, on south side of Marcola and on the east side of McKenzie River. .. iii SATRE ASSOCIATES 1-8 June 12,2001 I I I I I I I I I I I I I I I I The Eugene Water and Electric Board (EWEB) Hayden Bridge Water Filtration Station (Station) and the Hayden Bridge Boat Ramp are both located north of Marcola Road. The Station opened in 1950 and is on a 53-acre parcel. The Station is rated to pump 72 million gallons of water per day (mgd) from the McKenzie River and EWEB has water rights to 200 million gallons of water daily, which represents approximately 1% of the river flow. The Station pumps an average of 30 mgd; winter pump rates are 19 mgd and summer pump rates are 45-50 mgd. A remote water station with eight pumps and two filter screens is located immediately adjacent to Hayden Bridge. This remote station pumps water though two pipes to the Station, where water is filtered using a dual media method of course silica sand and anthracite coal. Sediment is removed with Aluminum Sulfate and the water is disinfected with chlorine. An expansion project for the Station will be constructed in 2001 and consists of a 15 million gallon reservoir, water sedimentation basins, new filters and pumps. Surroundin~ Transportation Network The principal arterial road that serves the site is Highway 126. In 1998, the average daily traffic volume for Highway 126 0.70 miles west of 1-5 in Eugene was 57,292 vehicles. This traffic count location is west of the site, but is presumed to be a fair representation of traffic volume on Highway 126 between Eugene and Springfield. Two minor arterial roads abut the site, 42nd Street and Marcola Road. At the southeast comer of the 42nd Street and Marcola Road intersection is a gravel area within Lane County right-of-way serving as the primary point of ingress and egress to the site. Existing bicycle lanes are located on Marcola Road north of the site and on Olympic Street southwest of the site. East of the site is a striped bicycle lane on High Banks Road from 52nd Street eastward. The City is currently developing plans for an off-street multi-use path located on the east side of 42nd Street on the side of a former railroad spur, immediately west of the site. 2-15 I I I I I I J ~ - ~ I - tn c ('II ''It I I I I I I ti 0: <II ~ i MCKENZIE RIVER OXBOW NATURAL AREA MASTER PLAN Map 2 June 12, 2001 I '. , I I Legend Inset: 1998 Aerial Photograph Not To Scale 1\1 Subject Site D Tax Lots N ~~i~~~9 Bikeway I \ I Planned Bikeway EEEJ100-year Floodplain Floodway ... · Utility Lines . . :WI:II!li Wellfield _ McKenzie River _ Tributary _ Wetland "!~1 Ponded Area D Slough ====-- I McKENZIE RIVER OXBOW NATURAL AREA MASTER PLAN Section Two: City Goals/Interests and Mayor's Task Force I I I I I I I I I I I I I I I I 2-17 I ~~ McKenzie River Oxbow Natural Area Master Plan I I I I I I I I I I I I I I I I CITY GOALS/INTERESTS AND MAYOR'S TASK FORCE Section 2 identifies Springfield City Council's expressed goals and interests, which provided a framework for this Plan, and involvement by the Mayor's Task Force, which was created during the initial stages of the planning process. CITY GOALS As an initial step in the project's public involvement program, the Springfield City Council met in a work session on July 17, 2000. The Council reviewed the scope of work for the project and Existing Conditions Report, and articulated its goals for the project and its interests in approaching selected issues. To frame the varied issues and factors that have bearing on the future use and management of the subject site the project consultants grouped major issues into four categories for Council consideration and deliberation. Issue areas involved environmental stewardship, the continued provision of public facilities, site and river access, and site uses and management. Environmental Stewardship Goal: To actively initiate environmental restoration projects and activities, and consider potential site modifications that would allow legitimate public uses to occur while still preserving the resource base. The City Council is interested in: · Promoting removal of invasive, non-native plant species from the site; · Actively managing the site to improve the site's aquatic and riparian habitats; · Providing public access to the site, at a level compatible with the site's natural qualities; · Developing opportunities for outdoor environmental education on-site; · Considering a variety of land tenure and management options; · Allowing legitimate public uses to occur, including exploring the establishment of an east-west bike route linking the Thurston area with mid-Springfield; and · Soliciting involvement and support from various existing groups and creating new groups or aIIiances to educate the community about the value of this resource and support restoration activities. ... - SATRE ASSOCIATES 2-1 June 12,2001 2-18 McKenzie River Oxbow Natural Area Master Plan I City Goals/Interests and Mayor's Task Force Provision of Public Facilities Goal: To maintain the existing level of use and function of public facilities on or near the site (e.g., groundwater wells, overhead electrical line, downstream water intake), but consider options that could either allow for potential expansion of groundwater capacity to meet future demand, or relocate wells and the overhead electric line elsewhere. .. - SATRE ASSOCIATES 2-2 June 12,2001 I I I I I I I I I I I I I I I I The City Council is interested in: · Maintaining the provision of clean potable water as a priority; · Continuing plans to remediate contaminant impacts to the wellfield; · Assuring that nearby underground utilities (e.g., fiber optic line within railroad right- of-way along 42nd Street) are preserved; · Exploring the potential for relocating or burying the existing overhead electrical line to reduce visual impact to and from the river and vegetation removal in easement; and · Exploring the potential for relocating existing wells to avoid contaminant sources. Site and River Access Goal: To provide enhanced public access to the site and river, while preserving the site's inherent natural resource values. The City Council is interested in: · Constructing a small safe, informal trailhead and trailhead parking area that is visible from, and proximate to the 42nd Street/Marcola Road intersection; · Developing trail access within the site that meets the provisions of the Americans with Disabilities Act; · Providing directional signage to the site; · Developing river access opportunities that are subordinate to the site's important ecological values (e.g., perhaps a canoe launch or accessible fishing pier if such facilities can be suitably developed, but NOT another boat launch). Site Uses and Mana~ement Goal: To provide for educational and passive recreational uses that do not harm site ecology or public facilities. The City Council is interested in: · Cultivating relationships with schools and non-profit educational groups to create outdoor environmental education opportunities; · Developing accessible, multi-use trails as called for in adopted local plans; · Establishing interpretive kiosks and other signage for self-guided environmental education; 2-19 I w.i:C~ McKenzie River Oxbow Natural Area Master Plan City Goals/lnterests and Mayor's Task Force I · Preventing the creation of an attractive nuisance and security problem by restricting hours of use, providing a mechanism for ongoing site maintenance, and using other methods of appropriate site management. I I MAYOR'S TASK FORCE The Task Force represents a broad base of user groups, interests and affected agencies, associations and property owners that have assisted the City and Satre in developing the Plan. The Task Force visited the site, reviewed the Existing Conditions Report, City Goals and Interests Report, Site Facilities Program Report and the draft schematic plan. Throughout the planning process, Task Force members were offered opportunities to review and comment on the project. The Task Force also reviewed and commented on the plan during its development.

Some populations occur in the open sunny edges of ash forests. Although they typically display an association with tufted hairgrass, some local populations are found in areas now dominated by tall fescue. Populations of 1. bradshawii do not respond well to ground disturbances, although seeds of 1. bradshawii float and embed in the soil more readily in disturbed sites. Some populations have therefore been located in areas of past ground disturbance. Bradshaw's desert parsley has been recorded occurring with many other plant species of concern including the Willamette Valley daisy, white-topped aster, Wayside Aster, and shaggy horkelia. In addition, Bradshaw's desert parsley, along with the Willamette Valley daisy, exhibits a preference for Bashaw Clay soils. Bradshaw's lomatium would not likely grow at this site .due to the sandy loam soils (well drained) and the extensive dominance of reed canary grass (Phalaris arundinacea). The Willamette daisy is generally found in open, wet prairie meadows of the Willamette Valley drainage basin. It has shown a preference for hydric silty clay or clay soils. Populations can be present in meadows with a history of pasture or hay use, but no recent tillage. The Willamette daisy has shown a preference for Bashaw Clay soils. White- topped aster can be located in open, wet and upland prairies of the greater Willamette Valley. The white-topped aster can be found in association with 1. bradshawii as both individuals share the same general habitat conditions. The Wayside Aster is generally found in upland prairies, open deciduous and mixed coniferous forests, especially in areas with poison oak. Shaggy horkelia is generally found in opens prairie areas and displays similar habitat conditions to the listed endangered endemic, 1. bradshawii. It can also be found in sandy or rocky flats and in open forested areas. Like Bradshaw's lomatium, the Willamette daisy, white-topped aster, Wayside aster, and shaggy horkelia would not likely grow at this site due to the sandy loam soils and the domination of reed canary grass (Phalaris arundinacea). Kincaid's lupine can be found in open grass-covered upland areas throughout the Willamette Valley. This species is also known to inhabit areas with habitat disturbances that include mowing, light grazing, and roadside clearings. The site is overgrown with blackberries, reed canary grass, shrubs, and trees, making this site an unlikely habitat for Kincaid's lupine. The Sidalcea (Sidalcea spp.) species of concern tend to grow in wet meadows, fields, upland prairies, ash swales, and along Willamette Valley roadsides. Habitat for Cusick's checker-mallow and meadow checker-mallow, which includes wetland prairie areas and ash swales, could be present at this site. These checker-mallows have been known to grow at the edges of wooded wetlands in the transition zone to open wetland areas. ... - SATRE ASSOCIATIS 3-7 June 12,2001 2-30 Site Characteristics I ~~ McKenzie River Oxbow Natural Area Master Plan Howell's montia can be located in open, bare soil understory areas of coniferous forests, mixed coniferous forests, and forest edges. Howell's montia can also be found in areas of habitat disturbances that include abandoned or seasonally used roads. Potential habitat could exist at this site for Howell's montia, particularly within the forested areas where neither the blackberries nor the reed canary grass have become dominant, and relatively little vegetation is present (e.g., the small areas towards the north of the project site near the banks of the river). - ...

McKenzie River V .' Habitat Area v, Existing Pond Turtle Habitat ~ Existing Fish Habitat ' _ Overlap of Existing Fish and Turtle Overlap I Site Characteristics ~~ McKenzie River Oxbow Natural Area Master Plan ~ The Western Pond Turtle (Clemmys marmorata) lives where water persists throughout the year, in ponds along foothill streams or in broad washes near the coast where water is concentrated from back country streams. The ponds favored by turtles are characterized by emergent and floating vegetation such as cattails and mats of algae. These islands of vegetation are usually large enough to ensure a fair supply of food and protection for the pond turtle. When undisturbed these turtles will sun themselves on rocks protruding from the pond or on partially sunken logs. Sometimes, they float on large patches of green algae. In cool weather, they leave the water to bask in the sun at favorite basking sites. During hot weather, they float in the cool water. At the first sign of danger, they quickly splash into the safety of the pond, where they become invisible to predators. In mid to late spring, the turtles breed and lay up to eleven eggs in a clutch (a group of eggs that is laid in the same place at the same time, or nearly the same time) and will hatch at the same time. The female deposits her eggs in sand or loose soil, usually near the pond. Hatchlings appear in about 12 weeks. Investigations as part of this study suggest that there are identified areas of suitable habitat although there are no known locations of Western Pond Turtle nesting areas on the subject site. I I I I I I I I I I I I I I o I Northern Red-Legged frogs prefer meadows and forests near wetland areas. Breeding is conducted in slow-flowing waters that contain submerged vegetation. Although no sightings have been recorded, the site does provide suitable habitat for this species. Bald eagles roost in tall trees along the coast, rivers, lakes, and marshes. The closest known evidence of bald eagles is along the Middle and Coast Forks of the Willamette River. These areas are more remote and removed from human activities. There are some tall cottonwoods and large red alders that could be used for roosting (with excellent foraging opportunities), but due to the nearby heavy traffic and industrial disturbances surrounding the site, nesting would be unlikely. Other avian species adversely affected by the loss of lowland riparian vegetation within the McKenzie River subbasin include: willow flycatcher, yellow-breasted chat, and osprey. Upper Willamette Spring Chinook and Summer Steelhead are known to be present in the McKenzie River and to use the side channels within the site. The site provides suitable habitat for spawning and rearing for Chinook Salmon. Summer Steelhead use this site for rearing, migration, and spawning. Issues affecting anadramous fish species include: migration barriers, increases in water temperature, competition for food with non-native aquatic species, and loss of rearing areas. To minimize impacts to wild Chinook and Steelhead species from anglers, state regulations allow only fishing for fin-clipped, hatchery-bred species above Hayden Bridge (to Forest Glen landing). f ~ - SATRE ASSOCIATIS 3-9 June 12,2001 2-33 Site Characteristics I McKenzie River Oxbow Natural Area Master Plan r " (J EXISTING SITE IMPROVMENTS Access A triangle shaped gravel area at the southwest comer of 42nd Street and Marcola Road serves as the primary access point for the site, and as an informal parking area and trailhead. Although the area is still owned by Lane County and was part of the 42nd Street right-of-way before the Marcola Road intersection was reconfigured, the entire 7,400 s.f. gravel area is within the Springfield city limits. A gravel maintenance drive extends parallel to 42nd Street due south from the trailhead area to a significant public groundwater wellfield located in the southerly portion of the site. Springfield Utility Board (SUB) and Rainbow Water District (RWD) personnel regularly use this drive for access to the wellfield, which provides much of north and mid-Springfield with potable water. The drive is approximately 12-15' wide, comprised of coarse compacted rock, and crosses Keizer Slough via a bridge with a concrete surface and railroad timber framing. - ... - SATRE ASSOCIATES 3-10 June 12,2001 I I I I I I I I I I I I I t I '~, Tile view looking nortll along tile maintenance drive An easement over the property allows SUB and R WD to use the maintenance drive as long as there are active public groundwater production wells in the wellfield. A gate located in the gravel area on the southeast comer of the 42nd Street and Marcola Road intersection controls entry to the maintenance drive. Another gate, immediately west of the maintenance drive gate controls access to the former railroad spur. Although public access on the maintenance drive is not authorized, the drive and bridge are used by anglers and others on the site. Illegitimate uses are easy to conceal due to the dense riparian vegetation and the fact that the elevation of the maintenance drive is approximately eight feet below the level of the former railroad spur, which runs parallel to the drive and screens direct visibility from 42nd Street. . 2-34 Site Characteristics =:t ii:~ McKenzie River Oxbow Natural Area Master Plan A view of Keizer Slough looking north from the bridge to the McKenzie River Wellfield The so-called Weyerhaeuser groundwater wellfield is jointly operated by SUB and RWD . and represents a significant contribution to Springfield's public water supply. The wellfield is an open field bounded by Highway 126 and the McKenzie River. Several large maple trees grow along the northerly boundary of the well field along the river. Other vegetation in the wellfield area consists largely of field grasses, which are periodically mowed to reduce the potential for fire hazard, and to increase visibility of the wellheads and.reduce the potential for vandalism. The McKenzie River's southern bank, north of the wellfield, is armored with riprap. The wellfield has three active groundwater production wells, two inactive wells and three monitoring wells; another monitoring well is located along at the southeast turn of the lower access road. The three active wells pump 3.6 million gallons of water per day (2500 gallons per minute). Security for the wellfield is a significant concern for water utility operators.

A monitoring well (MW 19D) located on the Weyerhaeuser property immediately south of Highway 126 is monitoring the direction of the plume twice a month. The plume is elliptical in shape and is approximately 1200 feet wide at its widest point, and approximately 4500 feet long and 70-80 feet in depth. The concentration of Penta in the aquifer is at 9-11 parts per billion at the MW 19D well. Federal regulations establish the value for Penta limits for non-human consumption species in surface water at 12 parts per billion; the limit for drinking water is 1 part per billion. Weyerhaeuser Company, SUB and RWD have collaborated to develop protocols for removing Penta from the public water supply when the plume reaches the Weyerhaeuser wellfield. It is estimated that the SUB and RWD monitoring wells located immediately east of the site could begin to detect Penta levels in 2001. The Weyerhaeuser Company paid for the construction of a filtration system located at the RWD site on 42nd Street to treat potable water supplies when Penta reaches the wellfield. When concentrations of Penta are detected in the water supply, water will be directed from the main transmission line to the filtration system. There the water will pass through a series of eight filtration canisters, each with activated carbon, which are specifically designed to remove the Penta from the water. It is estimated the Penta plume will enter the McKenzie River by the year 2008. Based on the dilution factors, once the Penta is in the McKenzie River it is not anticipated that it will be detected at levels that will pose a risk to human consumption, aquatic species or wildlife habitats. Overhead Electrical Line A 35-foot wide EWEB utility easement is located along the easterly boundary of the site that extends the length of the site immediately east of the maintenance drive. The lines provides 3-phase power to serve uses at the Hayden Bridge Station and Weyerhaeuser Company. Informal Trails Approximately 500 feet south of the maintenance drive gate is a ten-foot wide grassy pathway, created by informal use as a trail to access the McKenzie River. This swath of grass narrows to a width of a single person and is bounded by blackberry approximately thirty feet west of the river. There are numerous lateral trails traversing the site in multiple directions. Although made by informal use of the site, the trails may provide legitimate trail use in areas that will not adversely impact the ecological functions of the site. - r..

EUJ!ene-SprinJ!/ield Metro Area General Plan The Metro Plan is the official long-range comprehensive land use plan for the cities of Eugene and Springfield, their urbanizable areas, and surrounding area. The Metro Plan diagram designates the site for Park and Open Space uses. This designation forms an association between the site and some of the plan elements identified within the Metro Plan. Relevant goals, objectives and policies in the Metro Plan's Willamette River Greenway, River Corridors, and Waterway Element; Environmental Resources Element; Transportation Element; and Parks and Recreation Facilities Element serve as a framework within which project goals, objectives and recommendations must conform. Willamette River Greenway, River Corridors, and Waterway Element Findings in the Willamette River Greenway, River Corridors, and Waterway Element state: "In the Eugene-Springfield area, portions of the McKenzie River share equal importance [with the Willamette River] as a natural resource worthy of conservation and protection." Listed below are applicable goals, objectives and policies from this element: Goal: "Protect, conserve and enhance the natural, scenic, environmental, and economic qualities or river and waterway corridors.

" (pg. III -D-4) Environmental Resources Element This element pertains to natural assets and hazards of the metropolitan area. The site qualifies is a natural asset because of its wildlife and ecological value, and the fact that the McKenzie River is the sole source of drinking water for the city of Eugene and supports the aquifer system providing potable water to Springfield. Goal I: "Protect valuable natural resources and encourage their wise management, proper use and reuses, reflecting their special natural assets. " (pg.III-H-4) Objective 5: "Manage open space areas for their diverse and multiple values. " (pg. 11I- C-6) Objective 6: "Prevent damage to life and property and expenses associated with flooding and problem soils. " (pg. III -C-7) Several policies (e.g., Policies 1, 2, 3, 14, 20 and 28) are also relevant to the current planning efforts for the site because these policies address downstream impacts, FEMA regulations, development within the floodway, water quality and public awareness. Transportation Element The transportation element addresses surface transportation in the metropolitan area with an emphasis on the relationship between land use and transportation. The relationship of land use and transportation is addressed to respond to articulated community goals including: increasing public transit ridership; reducing automobile use; and increasing the use of alternative modes of transportation such as pedestrian and bicycle. Goal 1: "Provide for a more balanced transportation system to give mobility to all segments of the community. " (pg. III-F-4) - ilmII- - SATRE ASSOCIATES 4-3 June 12,2001 2-41 ~~ McKenzie River Oxbow Natural Area Master Plan Relevant Planning Documents Objective 4: "Promote the use of alternative modes of transportation such as bicycle, pedestrian, and paratransit to meet some of the trip needs of metropolitan residents. " (pg. III-F-4) Objective 8: "Promote land use arrangement, which will optimize use of existing and planned transportation facilities and services and will allow the choice of using alternative transportation modes. " (pg. III-F-4) Parks and Recreation Facilities Element The Metro area has a long history in providing diverse parks and recreation that enhance the livability of the community. The site has the potential to become an aspect of the overall recreation system within the Metro Area. Goal 1: "Provide a variety of parks and recreation facilities to serve the diverse needs of the community's citizens. " (pg. III-H-4) Objective 4: "Develop park sites and recreation facilities in the manner best suited to serve the diverse interest of local residents and in areas of greatest need. " (pg. III-H-4) Policies 1 and 2 are also relevant to the current planning efforts for the project site because they address including river corridors in recreation plans and coordination on a metropolitan level. Metro Plan Update Natural Assets and Constraints WorkinJ! Papers As a companion to earlier iterations of the Metro Plan, the 1978 Working Papers are inventories and analysis of a series of natural resource attributes throughout the Eugene- Springfield area, including the subject site. Although the information is now quite old and is mapped on a metropolitan scale, it is still instructive in that it identifies the area as possessing significant wetlands vegetation and wildlife areas, and identifies the McKenzie River as a spawning river for anadramous fish. The subject site was specifically identified as Site 34, Hayden Bridge Wildlife Area, and as home to two known avian wildlife species - Green Heron and Warblers. Draft Metropolitan Natural Resources Special Study Although a metro-wide NRSS has not been adopted to date, the 1991 NRSS Study Report offers valuable inventory data based on sound principles and recommendations for balancing human-built system and natural systems.

The NRSS recognizes the Weyerhaeuser A site as an area of great importance because of its connection to three nearby sites (i.e., S09- Weyerhaeuser, S20-Irving Slough North, and S21-South Irving Slough and Pond). The site is identified as having "a large riparian forested area with excellent structural diversity (multiple layers of vegetation), abundant sources of food, water and cover and strong connections to other wildlife habitat sites. Vegetation on the site is mostly native species, diverse and mature and includes black cottonwood, willow, snowberry, sedge, rush, cattail and reed canary- grass. The site is part of a major wildlife travel corridor and provides vital components of fish habitat for the river. The backwaters in this site provide a rearing site for many fish species. This type of aquatic habitat is typical of that used for rearing by the Oregon Chub, a candidate for the federal endangered species list. There is one active heronry on the site." The site is also identified as. important because it is part of a larger riparian forest area that borders the McKenzie River, which is also listed as a significant site (MC), with a high wildlife habitat rating. The NRSS notes the high quality of the riparian area along the river adjacent to the subject site, noting that it is "dominated by willow, black cottonwood and red alder, with big leaf maple, Oregon ash, creek dogwood and Indian plum. Structural diversity and density are high. The red-tailed hawk, osprey, great blue heron, green backed heron, mallard, common merganser and belted kingfisher are common inhabitants of these areas. These areas also support nutria, beaver, skunk, raccoon, bats, black-tailed deer, red fox and other small mammals. These areas are connected to other high quality riparian areas along the river and are important as part of the travel corridor provided by the McKenzie. In addition to providing wildlife habitat adjacent to the river, these riparian areas are a critical part of the biological system which supports fish populations in the river itself. The McKenzie River is renowned for its recreational fishing, including steel head, Chinook salmon, cutthroat and rainbow trout and mountain whitefish. These species, along with over 30 other fish species, depend upon healthy riparian areas to survive." The NRSS recommends development in these areas a manner that is sensitive to the high value and ecological sensitivity of the adjacent riparian area (i.e., protect the natural resource, provide waterside development. in appropriate areas and utilize the site for education purposes). The companion to the NRSS study report, the Metropolitan Natural Resources Functional Plan, contains detailed policies and recommended actions concerning the natural resource 4-5 June 12,2001 ... - SATRE ASSOCIATES 2-43 Relevant Planning Documents I McKenzie River Oxbow Natural Area Master Plan . system in the Eugene-Springfield metropolitan area. The subject site is recommended for protection, with limited waterside development and clean-up, restoration, and educational efforts allowed. All applicable policies and recommended actions for Natural Resources Policy (page 15-17), Waterside Protection and Development Policy (page 17-19), Public Access Policy (page 22), Clean Up, Restoration and Education Policy (page 22-23) have been incorporated into the Plan. 4-6 June 12,2001 I I I I I I I I I I I I I I , I McKenzie River Riparian Corridor Evaluation This study evaluates natural resources associated with four sites in the McKenzie- Gateway area approximately 2.5 miles west (downstream) of the site. This study is a site-specific document and evaluation, but provides some limited information applicable generally to the McKenzie River and upstream riparian areas. Future potential uses and management strategies for the McKenzie-Gateway site were recommended to be appropriate for the surrounding natural resources and the McKenzie River as a whole. Willamalane Park and Recreation District Comprehensive Plan The adopted 1980 Willamalane Parks Plan enumerates several policies, which warrant consideration when reviewing potential use activities and management strategies for the site. . "Work with Lane Transit District (LTD) in assuring that mass transit routing is convenient to existing andfuture Park and recreation facility locations. " (pg.l76) . "Work with appropriate public agencies in assuring that metro bikeways are convenient to existing andfuture recreation facility locations. " (pg. 176) . "Work with Lane County in evaluating lwid in close proximity to the District which are in the jloodway fringe or land generally unsuitable for other purposes for possible recreational potential.

"Evaluate the recreation potential for District residents and visitors of lands in close proximity to the District, lvhich are located in the jloodway fringe or are generally considered unsuitable for other purposes." (pg. 178) . "Consider environmental enhancement with regard to recreation development. Parks and recreation facilities shall be developed to insure that minimum of damage to the environment. " (pg. 178) . "Work to incorporate recreational amenities such as trail systems, bike paths and jogging trails within existing drainage ways, open space corridors and utility rights-of way so that these natural resources are retained as assets in the community's recreation system and natural environment, while still providing a high quality recreation experience for the District's residents and visitors.

The PROS Plan advocates: I) the development of a park and open space network; 2) the protection of unique natural values; and 3) the coordination, cooperation, and partnership with other agencies and the community. The plan was adopted only by Willamalane and not the City, so it has only advisory status. The PROS Plan identified the area northwest of the project site as a park deficient area and as a potential location for a park site. Along the westerly boundary of the site along 42nd Street, a planned multi-use path is shown on the Recreation Corridors Diagram. In the PROS Plan, Willamalane also recommends the City obtain funding for the development of a pathway linking the Thurston area with mid-Springfield and the rest of the community. Specifically, the PROS Plan identifies a recreation corridor (see below) that would connect the existing bikeway through north Springfield (the EWEB Bikeway) to Marcola Road, the Weyerhaeuser property, High Banks Road, and east Springfield. The specific pedestrian corridor linkages identified in the PROS Plan are relevant to the current planning effort for the project site. ~ -- L..-- - "'...----------, , ~., .... ., ...... ...... =] --_._--"-"._~, ~ - ~',^,,~.-----. ~-~ --..,-- -"".. ."..... ...... --.- " ---., '~- L L_.....

SATRE ASSOCIATES 4-7 June 12,2001 2-45 Relevant Planning Documents I McKenzie River Oxbow Natural Area Master Plan EUJ(ene-Sprimdield Metropolitan Area Transportation Plan The 1986 TransPlan recommends a McKenzie River Path, Project #688, from 420d Street to High Banks Road. This project is on a medium ranre project schedule. Another project on the medium range project schedule is the 420 Street Route, Project #733a, which is recommended to connect Marcola Road to the Weyerhaeuser site. 4-8 June 12,2001 I I I I I I I I I I I I I I , I The EUJ(ene-SprinJ(field Transportation System Plan Update The 1999 draft TransPlan Update sets policy recommendations for regional bikeways and pedestrian circulation and provides a framework for bicycle and pedestrian corridor improvements in proximity to the project site that would allow the project site to become part of a larger bicycle or pedestrian corridor network. The TransPlan Update recommends a striped lane from Marcola Road to the railroad tracks, Bicycle Project # 713. The McKenzie River Path, Bicycle Project # 753, a multi-use path from Marcola Road to 520d Street is also recommended in the TransPlan Update. The above referenced planning documents show the project site to be an important property with regard to preserving it as a natural asset and as a potential link to connect some of the fragmented portions of the bikeway network in proximity to the project site. SprinJ(field Bicycle Plan The Springfield Bicycle Plan is a 20-year projection of the City's bicycle system needs, which takes into account safety, connectivity, convenience, and visual aesthetics for on- street and off-street bicycle transportation. The Bicycle Plan was adopted in 1998 by the City of Springfield and refines the bicycle element of the TransPlan. The Bicycle Plan identifies the area immediately adjacent to the site as a highly fragmented bikeway network. Currently there is no effective means to link the Thurston area with mid- Springfield for bicyclists. The portions of the bicycle network that is in proximity of the project site received a fair to superior rating for level of service. Presumably, any addition to the. bikeway system in and around the project site would provide highly needed linkages. The Bicycle Plan's "Priority Projects Map" shows a proposed multi-use path called the McKenzie River Connector on the southern boundary of the project site. This multi-use path will provide a vital link in the City's fragmented bicycle network. The City of Springfield has received an ODOT matching grant to develop a bike path on the old railroad spur parallel to 420d Street from Marcola Road to the Weyerhaeuser property located south of Highway 126. The City is developing in 2001 a work plan and engineering drawings for the project. ~. - SATRE ASSOCIATES 2-46 I Relevant Planning Documents ~.~ McKenzie River Oxbow Natural Area Master Plan I I I I I I I I I I I I I I r ~ I -- SATRE ASSOCIATES Project Site -a"s!.

Federal A~encies National Marine Fisheries Service Improvements to the site will need to be coordinated with the National Marine Fisheries Service (NMFS) to ensure a "take" of federally protected aquatic species (Evolutionarily Signficant Units, or ESUs) or habitat does not occur. NMFS has jurisdictional responsibility to protect ocean species, including anadramous fish such as salmon, that spend part of their life-cycle in freshwater environments, and part in oceanic habitats. In June of 2000, NMFS adopted provisions to implement prohibitions of "takings" of 14 groups of salmon and steelhead listed as threatened and endangered under the federal Endangered Species Act (ESA). NMFS adopted the take rule under section 4( d) of the ESA. This rule prohibits anyone from taking a listed salmon or steelhead except in cases where the take is associated with an approved program. The 4( d) rule approves some specific existing state and local programs and creates a means for NMFS to approve additional programs if they meet certain standards set out in the rule. This rule protects 14 ESUs of salmon and steelhead in Idaho, Washington, Oregon, and California. The rule's principal function is to prohibit actions that kill or injure threatened species (i.e. "take" them) without specific written authorization. The 4(d) limits are not the only mechanism for NMFS and other applicable federal agencies to review activities to ensure they do not harm salmon. Section 7 of the ESA requires that federal agencies (and their assignees) consult with NMFS on activities they authorize, permit, fund, or carry out to ensure they are not likely to jeopardize the continued existence of listed species or destroy or adversely modify their critical habitat. The 4(d) rule's prohibitions on take apply to the activities of every state, city, and county government, business, and citizen. The take guidance described in the final rule provides information about what types of activities are most likely to result in a take and thus violate the 4(d) rule. However, each activity must be evaluated on a case-by-case basis to determine if it is likely to cause take. Protocols for ensuring agency compliance with the 4( d) rule is generally described below. I. Identify the program or activity (for state and local governments, this may include activities they fund, authorize, or carry out); 2. Evaluate whether the program or activity is likely to take or harm listed fish or their habitat; ..- - SATRE ASSOCIATES 5-1 June 12,2001 2-49 Regulatory Requirements I ~L~ McKenzie River Oxbow Natural Area Master Plan 3. If the program or activity is not likely to take or harm listed fish, then there is no need to modify the activity or for the federal agency involved in the project to contact NMFS; 4. If, however, after reviewing the program or activity, it seems likely it will take or harm listed fish, or there is uncertainty about whether take or harm may occur, the acting party should contact NMFS to find out more about how to evaluate the activity's impacts and determine ways to avoid harming the fish and violating the ESA. '-111 - SATRE ASSOCIATES 5-2 June 12, 200 I I I I I I I I I I I I I I I , I US Army Corps of En~ineers (Corps) The Corps has jurisdiction over the waters of the United States, which include jurisdictionally delineated wetlands, ponds and waterways including the McKenzie River, Keizer Slough and the wetlands on the site. The Corps also has a primary role in developing and maintaining flood control devices throughout the entire Willamette River basin. As a product of this latter mission for flood control, an overriding objective of the Corps in the project area is to retain the function of, and maintain access to, the revetment structure (riprap) north of the wellfield to be undisturbed. This does not preclude enhancement projects to the revetment (i.e., adding vegetation), but the Corps would review proposals to evaluate impacts to the function and protection of access to the revetment, as well as any potential ESA take issues. Any fill or removal of soils or construction activities involving more than 50 cubic yards of fill in a year, and projects involving wetlands or waters of the United States would need to be coordinated with the Corps. Also, any improvement to the site that may impact the water's flow would also need to be reviewed by the Corps for hydrologic impacts. US Fish and Wildlife Service (USFWS) The US Fish and Wildlife Service has jurisdiction over all other listed flora and fauna, as well as non-anadromous fish species, such as Bull Trout. Any improvement that may affect these species would need to be coordinated with the USFWS. State Agencies Ore~on Division of State Lands (DSL) The DSL has jurisdiction over waters of the State of Oregon, including jurisdictional wetlands. Any improvement projects that impact these waters will need to be coordinated with the DSL. Since the DSL and ACOE both have jurisdiction over wetlands and waters for their respective agencies, a coordinated review and permit (a Joint Permit) would be necessary. 2-50 I McKenzie River Oxbow Natural Area Master Plan Regulatory Requirements I I I I I I I I I I I I I I r I Ore~on Department of Fish and Wildlife (ODFW) OOFW has jurisdiction over anadromous fish species and state listed endangered or threatened species. The ODFW also serves as a conduit in which some Federal regulations are enforced within the state. ODFW will be involved in any section 7 or ESA consultation undertaken by NMFS. Ore~on Department of Transportation (ODOT) OOOT has jurisdiction over state highways and roads. Eugene-Springfield Highway 126 is under ODOT jurisdiction. Any improvement that may occur within the ODOT Highway 126 right-of-way will need to be coordinated with ODOT. Local Aeencies Lane County The site is outside of Springfield's UGB. Therefore, Lane County has jurisdiction over land use, development, and fill/removal activities on the site. In a work session on March 13th, 2001 the Lane County Board of Commissioners reviewed but did not act upon the recommendations of the Lane County Planning Commission. These recommendations called for the creation of a Critical Habitat Conservation Zone (CHCZ) in response to the listing of bull trout, Oregon Coast coho, and Upper Willamette spring Chinook as threatened species under the Endangered Species Act and the 4(d) rule. The CHCZ would supersede the Class I Stream Riparian Regulations (LC 16.253) and supplement the Willamette Greenway Development Permit (LC 16.254) and Floodplain Combining Zone (LC 16.244) code provisions. Any future improvement to the site will need to meet the criteria and standards set forth in the Lane Code. The following table illustrates the permitting requirements for uses and improvements proposed on the site through this planning effort. - Ill. - SATRE ASSOCIATI5 5-3 June 12,2001 2-51 McKenzie River Oxbow Natural Area Master Plan Regulatory Requirements Table 3: Potential Permit Requirements for Proposed Improvements and Uses.

An overlay analysis method was used, which "stacks" the existing natural features, sensitive areas, critical resources, and regulatory setback requirements to identify those areas that have potential for site improvements (refer to Map 5- Site Analysis). SITE ANALYSIS As noted earlier, the total area of land reviewed as part of the site analysis (refer to Section 6) is approximately 107 acres; this additional area includes portions of the McKenzie River and its features that are adjacent to tax lots 401 and 2901, which are not owned by the City. Below are definitions for some of the terminology used in this section of this Plan. Physical Improvements: Any physical change or alteration to the site resulting the construction of new structures or modification of existing structures (structures is defined as any human-built feature temporarily or permanently stationed in the landscape). Restorative Improvements: Any alteration or modification to any natural feature that, in some way, improves said natural feature (e.g., McKenzie River, wetlands, vegetation). Restorative Areas: Those areas that have been identified through the planning process as needing restoration to vegetation and/or the land base. Restoration might either occur through the removal of non-native invasive vegetation, enhancing existing riparian vegetation, or improving habitat in critical resource areas. When reviewing existing natural features, the site analysis used the following criteria were developed to assist the City with identifying those areas that have potential for physical improvements. · Previously disturbed areas; · Areas outside any regulatory setback or jurisdictional wetland; · Areas outside of the floodway; · Areas outside of any known critical habitat area; · Areas located away from any existing rare plant and animal species; · Areas outside of the existing wellfield (certain measures that address security and contamination concerns could provide potential for minor improvements to those areas in proximity to the wellfield). ... - SATRE ASSOClAm 6-1 June 12,2001 2-54 ' Site Analysis and Uses I ii:~ McKenzie River Oxbow Natural Area Master Plan ANAL YSIS METHODOLOGY The site analysis process included the following steps. 6-2 June 12,2001 I I I I I I I I I I I I I I , I Site Visit: The consultant team made numerous visits to the site to assess physical conditions, map wetlands, rare plant communities, and review proposed improvement scenanos. Document Review: Section 4 of this plan documents the applicable plans and planning documents reviewed as part of this project. These plans have provided insight potential opportunities and constraints for improvements. Meetings: The consultant team, City staff and Task Force met numerous times to discuss project findings, proposed scenarios and potential improvements. Mapping: Once identified, the critical habitat areas, natural features, regulatory requirements and existing improvements were mapped in order to graphically display those areas that have potential for improvement. Findinf!s Based on the overlay method of analysis, the project area was divided into three areas. These areas are identified as 1) unsuitable for physical improvement, 2) suitable for improvement, and 3) suitable for improvement with mitigation. 1) Unsuitable areas for physical improvement are those areas found to contain features or resources that would be adversely impacted by improvements. 2) Suitable areas for improvement are those areas that, if improved would result in minimal adverse impact existing natural features or resources. 3) Suitable areas for improvement with mitigation are those areas where some degree of on-site mitigation would be necessary to ensure minimal adverse impact. Of the approximate 107 acres in the project study area, 6 acres are suitable for improvement, 29 acres are suitable for improvement with mitigation, and 72 acres are unsuitable for improvement. Please note that the area that comprises the unsuitable for physical improvement area includes those areas not owned by the City, including the McKenzie River and its tributaries. Physical improvements may occur in suitable areas for improvement and suitable areas for improvement with mitigation.

Mitigation necessary for physical improvements is greatly dependent on the improvement being proposed and the impact. However, in general, mitigation could include: creation of additional wetlands, planting of riparian vegetation, and expansion of public educational programs occurring on the site. This analysis assumes all the current authorized uses (i.e., well field production and maintenance, electric utility corridor and storm water management by the City of Springfield) will continue to occur on the site. Any expansion of these uses should be allowed with the appropriate mitigation measures to ensure minimal adverse impact to the ecological function of the site. Opportunities Public Education The site is a function of dynamic habitat, features and attributes that demonstrate the importance of environmental stewardship. An environmental education program focus for the site can promote a community awareness about how this site functions and why the function of this site is so important. The education format can promote important role the public well field serves to the community, how storm water is managed and the importance of the ecological function of the site. The City can encourage partnerships with local school districts (i.e., Springfield School District #19 and Eugene District # 4J) to form create volunteer youth corps for restoration projects. Wetland Miti~ation This site has been the site of wetland mitigation in the past and may serve as a receiving site for additional wetland mitigation for the City. The site has potential habitat enhancement areas, which can be included in future mitigation. Storm Water Mana~ement The site is currently used for stormwater management and if necessary this use can be expanded in concert with an educational program to highlight the benefits of storm water management and vegetative restoration. Restoration Restoration can include enhancements and rehabilitation for habitat, vegetation and/or wetland environments on the site. The site has numerous areas that contain invasive, non-native species; these species can be removed through restoration efforts and 6-3 June 12,2001 ... - SATRE ASSOCIAm 2-57 Site Analysis and Uses I ~~ McKenzie River Oxbow Natural Area Master Plan management.

Conservation may include ongoing management and maintenance of public areas to assure minimal impacts to adjacent areas that may be at risk, or it may include vegetation and habitat management. Multi-use Connector (McKenzie River Multi-use Path) The Springfield Bicycle Plan documents the need for an east-west pedestrian connection that connects the Thurston area with mid-Springfield. There is an opportunity for such a connection through the southern portion of the site. The City of Springfield is in the design phase for the 42nd Street Pathway, which will be located on the former railroad line, immediately west of the site. A multi-use path, the McKenzie River Multi-use path, extending from the 42nd Street Pathway to High Banks Road may be achieved by traversing the southerly portion of the site starting in the southwest corner and continuing along the southern portion of the site adjacent to the Highway 126 right-of-way to High Banks Road. Because of the narrow dimensions on the southern portion of the site, and to allow for potential funding and maintenance benefits, portions of the route may need to be placed within portions of the Highway 126 right-of-way. Constraints The constraints to physical improvements on the site are well documented and include issues concerning floodways, wetlands, sensitive habitat (plant and wildlife) areas, riparian areas, the wellfield, and the McKenzie River. These constraints also reflect the site's tremendous ecological assets and should be incorporated into restoration, conservation and education efforts of the site to serve as a method of creating a public awareness of the importance of the ecological function of the river. SITE USES The opportunities and constraints for the site shape the type of appropriate uses for the site.

McKenzie River Oxbow Natural Area Master Plan I I I I I I I I I I I I I I r I ENHANCEMENT PLAN Narrative in this section accompanies Map 6, the illustrated Site Enhancement Plan. The importance of environmental stewardship, education and awareness is the overriding philosophy of the enhancement plan. Allowing the site to continue its ecological function and its role as a public drinking water production site, and storm water management site are equally important. This philosophy is one that utilizes the existing natural resources and existing uses as a framework to guide potential uses and improvements in a manner that minimizes any adverse impact to the environment or public interest Desi~n Approach The design approach used for enhancements is based on: · Use the site's natural features to maximize public awareness; · Create site uses, management techniques and programs that will support the notion of environmental stewardship; · Integrate the existing uses of the site into future use and management policies; · Create a plan that can adapt to future public and city needs; · Create an overall design that is based on several factors that although compliment one another, are not strictly dependent one another; · Create a plan that can be realized and maintained within acceptable fiscal parameters; · Allow this plan to provide the framework for future improvement projects for the site. Initial Plan The City Council, staff and the Task Force reviewed the draft schematic design and their comments have been used to create the Enhancement Plan. A draft schematic plan established the framework for improvement by dividing the site into three areas: 1) preservation zone, 2) conservation zone and 3) a multi-use path zone. Each area had particular uses and improvements proposed to promote the site and its features including wellfield groundwater production, passive recreational uses (i.e., walking, river watching, wildlife viewing), multi-use path, conservation trails, educational programs, and vegetation restoration. Enhancement Plan The Enhancement Plan evolved from the initial plan scenario with the following changes: · Proposing uses based upon suitability; · Expanding uses to include wetland mitigation and storm water management; · Emphasizing education as a focus of the overall design philosophy and approach; · Shifting the focus from site recreation type uses to education type uses, although the site will have a similar function 7-1 June 12, 2001 - ... - SATRE ASSOClAm 2-64 Enhancement Plan I ~~ . McKenzie River Oxbow Natural Area Master Plan · Establishing the multi-use path as a linked but separate component ofthe plan to provide the City with greater flexibility in phasing and implementation; · Increasing awareness of plant species and wildlife habitats. · Promoting vegetation management and restoration; · Promoting uses that support a high level and quality of ecological function. I I Table 8: Proposed Uses/lmprovements and Applicable City Project Goals I I I I The physical layout of the Enhancement Plan and the uses for the site are based on integrating the potential improvements and uses into the site compatible with the existing and future ecological function of the site (refer to Map 6, Enhancement Plan). The Enhancement Plan is comprised of three areas including: 1) Areas suitable for improvement; 2) Areas suitable for improvement with mitigation; and 3) Areas unsuitable for physical improvement. The following tables summarize the how the proposed uses and improvements address and satisfy the City's goals and interest.
