Report 9

I. INTRODUCTION

The preliminary staff recommendations represent the initial findings and conclusions of the West Eugene Wetlands Special Area Study (WEWSAS). The findings are derived from a variety of sources, including the material contained in the report prepared by Scientific Resources, Inc., Wetland Inventory and Wetland Functions and Values in West Eugene, Oregon, response from the four previous public workshops, advice and comments from the WEWSAS Technical Advisory Committee, federal and state wetland law and the Memorandum of Agreement on wetland mitigation between the Environmental Protection Agency and the Army Corps of Engineers.

The preliminary recommendations include:

A Concept Plan Statement

List of Goals and Objectives

Criteria used in developing recommendations on individual wetland sites

Map showing wetland sites to be protected and available for development

Map showing possible "off-site" mitigation sites that promotes a connected wetland system along established waterways.

The public is encouraged to review and comment on the recommendations. A survey/questionnaire will be available at the workshop and at L-COG offices that asks the public to respond to each component of the preliminary staff recommendations. Please take time to complete and return the questionnaire by June 15, 1990, 5:00 p.m., Lane Council of Governments, 125 East 8th Avenue, Eugene, OR, 97401.

Results of the public's response to the recommendations will be compiled, evaluated and made available for review. Results will be used to prepare a staff recommendation for inclusion into the Draft WEWSAS, due to be released in late summer, 1990.


 
II. SUMMARY RECOMMENDATIONS

The preliminary staff recommendations both describe and quantify the effects of the recommendations. The Concept Statement and the list of Goals and Objectives provide an overall perspective of the type of wetland system proposed. The statement responds to the public's preference to provide economic development opportunities in lower value wetlands where public infrastructure exists or can be readily extended. It also incorporates the public's desire for enhancing and maintaining a sustainable, connected wetland system that supports a variety of wetland types, a diversity of wildlife and plant species, provides increased flood storage, and opportunities for educational and recreational activities.

The recommendations for individual wetland sites results in the following acreages for protection and development:

III. PROCESS AND METHODOLOGY

The preliminary staff recommendations were developed using the following process:

The best available information was collected regarding the location, quantity and quality of existing wetland resources. The SRI report for the WEWSAS and the 1988 Lev report, Preliminary Inventory of Eugene & Springfield Wetland, Riparian & Upland Areas for Wildlife Habitat Value , provides this information.

The content of the report was reviewed for completeness and accuracy by the WEWSAS Technical Advisory Committee (TAC), City of Eugene and L-COG staffs and the general public. Where appropriate adjustments to the report were made.

The legislative requirements of federal and state wetland law were identified and used as the basic framework for analysis.

The basic framework of federal and state law was supplemented with local input. During a series of four public workshops, local input for wetland goals, objectives, criteria for evaluating individual wetland sites and management scenarios was collected utilizing a variety of techniques including bean jar surveys, questionnaire/surveys, group discussions and written comments.

Other known and anticipated constraints were identified and included in the analysis, such as the need to provide adequate amounts of urban industrial and commercial land for future growth and the new storm water quality discharge standards required through the federal clean water act.

Through a series of interagency team meetings, the results of the input from the public and the TAC were evaluated and a package of preliminary staff recommendations was developed consisting of a concept plan, list of goals and objectives, criteria and recommendations for development and protection of individual wetland sites.

Future process includes the review and comment of the preliminary staff recommendations by the general public and the TAC. Comments will be reviewed and adjustments made and contained in the Draft WEWSAS due to be released in late summer 1990.


 
 

  IV. RECOMMENDATIONS


A. CONCEPT STATEMENT.
This statement is intended to help gain a sense of the vision which underlies the recommendations presented below. To facilitate that vision, imagine living in the year 2010 - twenty years in the future! From that perspective, reflect upon what has come to pass in west Eugene as a consequence of decisions made in 1990 about protecting wetlands while providing for the development needs of the community.

West Eugene Wetlands - Reflection

The City of Eugene recently celebrated the 20 year anniversary of the adoption of the West Eugene Wetlands Plan. Since its adoption, most of the Plan's recommendations have been completed resulting in a national award for Community Development where wetland resources have played a major role in improving the area's natural resources, economic diversity and meeting some of its utility needs.

West Eugene waterways are once again connected by a functioning and sustainable system of protected, enhanced, and restored wetlands. Ash and cottonwood forests, prairie grasslands, and shallow ponds provide a diversity of wetland types. Natural functions, such as flood control, water purification, rare plant and fish and wildlife habitats have been restored and are now important components of the community's urban form. Inside the city, people can watch beaver, red fox, ring-necked pheasants, and great blue herons. At the wetlands interpretive center, children delight in finding tadpoles, frogs, dragonflies, and turtles. Residents and visitors enjoy the wetlands as they fish, bicycle, canoe, and study nature along a system of paths, trails and viewpoints. The Amazon Bike Path is complete, providing a connection from Downtown through the wetlands to Fern Ridge Reservoir.

Economic development has moved forward in west Eugene. A new trend was established where new development incorporates wetlands as both an amenity and utility. New business parks use natural and enhanced wetlands as an integrated system of open space, water quality treatment and flood protection. Employees enjoy the wetlands and the natural settings project a positive image for customers. The West Eugene Wetlands Interpretive Center is now a major tourist attraction for visitors traveling to this region. Educational benefits have been great! The new middle school purposefully located next to Willow Creek Natural Area and has incorporated wetland ecology as a major component of its curriculum. And, both of Oregon's major Universities have graduate level studies of national renown taking place in the region's wetlands.

In her remarks accepting the award, the mayor noted that the community should take pride in the accomplishments of the last twenty years. Eugene has protected the liveability of the area with the cooperation of political and business leaders, environmental groups, property owners, and an involved citizenry. She also indicated that the treatment of wetlands in west Eugene was proving to have a very positive effect on the local economy in terms of business attitude and community image. Special recognition was given to the non-profit group, "Friends of the Amazon", whose volunteer efforts helped make the west Eugene Wetlands Plan another success story for Oregon.


 

B. Recommended GOALS and OBJECTIVES.
These are draft goal and objective statements based mostly on comments received from citizen workshop numbers 1-4. Goals and Objectives provide the basic direction that the plan is intended to pursue. They will be used to help formulate public policy from which future decisions are based regarding wetland related issues.

- Restore historic wetland types and types identified as desirable by the community for meeting local needs

- Buffer wetlands from surrounding incompatible uses

b

- Develop a wetland management plan which sets a national precedent in meeting federal and state requirements.

- Develop a wetland management plan which meets community desires

C. Recommended CRITERIA:

Recommendations for protection or development of individual wetland sites were based on the following criteria. Most of the criteria were developed using the survey results of Workshop No. 4 and the comments from the TAC.

PROTECT:

> Rare Plants

> Existing Metro Plan Natural Resource Designation

> Within 100 Year Floodway

> Proximity to Waterway

> Interconnected units of wetlands and waterways

> High habitat diversity

> Furthered attainment of Goals and Objectives

DEVELOP:

> Approved permit from regulatory agency

> Isolated, disconnected from system

> Presence of public infrastructure (streets and roads, sanitary sewers, water)

> Proximity to existing development

> Proximity to major highways - frontage



D. Individual Wetland Sites. Refer to Exhibits "A", "B" and "C", attached.

The following describes the basis for staff recommendations of individual wetland sites. Sites were evaluated against the recommended Goals and Objectives, the Proposed Concept Plan and Criteria described above. Descriptions are listed in alphabetical/numerical order; however, where descriptions are common to more than one wetland site, each applicable wetland is referenced and grouped as a whole.

To locate a specific wetland site, refer to the attached wetland site map, Exhibit "A." The map corresponds to the reference system below. The first letter of the numbering system refers to an assessment area, such as "A"; the following number refers to the specific wetland site. When a small letter follows the number, that means there is more than one wetland site associated with a specific hydrologic unit, such as A1a and A1b.

The use of the term WET (Wetland Evaluation Technique) refers to a software program that was used to assess the functions and values of each wetland. WET provides a general assessment of the existing performance of a wetland and its potential performance for each function and value. Functions and values are given a rating of either High, Medium or Low. To provide a measure of how well each wetland is performing against all other wetlands in the study area, the mean WET score was determined. For sites scoring at or greater than the mean, a Protection point was awarded; for all other sites, a Development point was awarded.

A similar assessment process was used for Wildlife Habitat rating. The Lev Report provided the basis for wildlife habitat scores. The mean was determined at, again, those sites that scored at or greater than the mean, a Protection point was awarded and conversely, a Development point was awarded for lower scoring sites.

For a complete explanation of the evaluation process, refer to the WEWSAS packet prepared for Workshop No. 4, February 24. 1990. Copies may be purchased at the offices of Lane Council of Governments, 125 East 8th Avenue, Eugene, Or.
