Wetland help for Salem-area projects
Salem and Keizer sit on the floor of the Willamette Valley, where wet fields, seasonal swales, and creeks like Mill Creek, Pringle Creek, and Claggett Creek run through land planned for homes, schools, and commercial buildings. Many of those sites have wetlands that need to be located and documented before a project can move forward.
Zion Natural Resources Consulting has done wetland work in the Salem area since 2002. We delineate wetland boundaries in the field, map them with sub-meter GPS in ArcGIS Pro, and prepare the reports and permit applications Oregon DSL and the U.S. Army Corps of Engineers review.

Field delineation
We examine soils, hydrology, and vegetation and survey the wetland boundary and sample plots.
- 3
Report to DSL
We prepare the delineation report for DSL concurrence and answer reviewer questions.

Questions
Salem wetland questions
Do I need a wetland delineation before I build in Salem?
If your site has mapped wetlands, waters, or hydric soils, or if the city'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.
The wetland inventory shows nothing on my lot. Am I in the clear?
Not always. Small, seasonal, and forested wetlands are often missing from inventory maps but are still regulated. If part of the site stays wet in winter or spring, it is worth a field check before you finalize plans.
Can you work with my engineer and surveyor?
Yes. We coordinate directly with civil engineers and surveyors so wetland boundaries, buffers, and impact areas line up with the site plan.
