Wetland help for Eugene-area projects
Eugene sits at the south end of the Willamette Valley, where seasonal wet prairie, Amazon Creek and its tributaries, and the wetlands of west Eugene meet growing neighborhoods and commercial areas. Sites in Eugene, Springfield, Veneta, and Junction City often have wet soils or mapped wetlands that need to be documented before a project can move forward.
Zion Natural Resources Consulting delineates wetland boundaries in the field, maps them with sub-meter GPS in ArcGIS Pro, and prepares the reports and permit applications Oregon DSL and the U.S. Army Corps of Engineers review.

Questions
Eugene wetland questions
Do I need a wetland delineation before I build in Eugene or Springfield?
If your site has mapped wetlands, waters, or hydric soils, or if the city's or county's land use review sends a wetland notice to DSL, you will likely need one. A delineation shows exactly where the wetland boundary is, so your site plan can avoid it or account for it.
My field is dry in summer. Can it still be a wetland?
Yes. Many valley wetlands, including wet prairies, are saturated only in winter and spring. Wetland delineations look at soils, plants, and hydrology together, so a site can qualify even if it is dry when you see it.
Do you work outside Eugene city limits?
Yes. We work throughout Lane County, including Springfield, Veneta, Junction City, Creswell, and Cottage Grove, and across Oregon.
