Wetland Mitigation Banking Program

Special Announcement: We are Growing! 
Work is underway at Eugene's newest wetland mitigation bank, Amazon Prairie

The 329-acre parcel is west of the Eugene Airport and adjacent to Clear Lake, which was formed by a dam on Amazon Creek. This is the same Amazon Creek with headwaters originating in the Ridgeline Park System on the flanks of our iconic Spencer Butte. The creek begins in forested hillsides and flows through parks, our city, the West Eugene Wetlands, agricultural lands, and then continues north of Amazon Prairie to join the Long Tom River.

This first phase involves earthwork, seeding, and planting on over 140 acres of former ryegrass field. Over the next several years and in two phases, Eugene intends to restore a 320-acre matrix of wetland, upland prairie, and riparian habitat.
Coyote Prairie North Mitigation Bank 
Established following more than twenty years of research, knowledge, and experiences gained from implementation of the nationally acclaimed West Eugene Wetlands Mitigation Bank the Coyote Prairie North Wetland Mitigation Bank will continue to provide limited credits for compensatory wetland mitigation for Palustrine Emergent / Slope-Flats wetland types for the next few years.
Service Area for the Mitigation Bank
The service area for the Coyote Prairie North Wetland Mitigation Bank outlines the area within which the Bank is permitted to sell credits to potential developers seeking compensatory mitigation for Palustrine Emergent wetlands. The Bank’s service area includes a large geographic region in the southern Willamette Valley up to the 600’ elevation contour in an area extending from just north of Cottage Grove to west of Salem and includes the communities of Eugene, Springfield, Goshen, Veneta, Junction City, Harrisburg, Monroe, Halsey, Coburg, Lowell, Creswell, west Lebanon, Brownsville, Corvallis, Albany, Millersburg, Falls City, and others.

Guidance on Replacement Ratios

The regulating agencies will work with you to determine replacement ratios for your project. However, if your project is within the boundary of the West Eugene Wetlands Plan, the replacement ratios are described in section 4.17 of the plan. For more information on the default ratios and possible ratio reductions for projects within the West Eugene Wetland plan boundary, please refer to the Habitat Quality Assessment (HQA) documents below.

What are the Benefits of a Wetland Mitigation Bank? 
The Coyote Prairie North Mitigation Bank restores or enhances wetland habitats and sells credits to permittees as compensatory wetland mitigation as a requirement of their approved Joint Permit Application from the Department of State Lands (DSL) and U.S. Army Corps of Engineers.

The Coyote Prairie North Mitigation Bank is a large-scale, ecosystem-oriented wetland restoration project designed to provide sustainable ecological benefits in advance of unavoidable impacts to wetlands caused by human activity and provides a comprehensive, effective, and high-quality solution to compensatory wetland mitigation. Mitigation banking provides developers, utility providers, and state and local agencies with the opportunity to pay a one-time fee to purchase credits from the bank, thereby satisfying all or a portion of the statutory wetlands mitigation requirements. 


The Coyote Prairie North Wetland Mitigation Bank functions to serve two major goals: 

  • Provide mitigation credits for sale to private and public entities for development impacts located within the Bank’s service area. 
  • Restore and enhance an interconnected system of local wetland habitats to a high ecological standard.

The Coyote Prairie North Wetland Mitigation Bank has significantly advanced the science of wetland restoration by implementing the latest restoration and enhancement techniques and carefully monitoring its projects. Our restoration staff has undertaken projects that set a very high standard by establishing rare species, achieving high species diversity, and putting a long-term stewardship plan in place. This effort has resulted in some of the highest-quality wetland restoration projects in the Pacific Northwest. Our restoration techniques have created mitigation bank sites that have won numerous awards and are generally recognized as the “gold standard” of wetland restoration in Oregon. 

 The City of Eugene’s wetland mitigation sites provide significant benefits to the community including: 

  • Enhanced air and water quality treatment for non-point source pollution. 
  • Flood control and water quality treatment through an interconnected system of wetland and riparian areas. 
  • A diverse array of native plants and animals, and significant connected system of wildlife habitats. 
  • Access to large and interconnected natural areas near downtown Eugene for all citizens to enjoy. 
  • Educational and recreational opportunities in and along the wetlands and stream corridors.
