Delineation Resources

Environmental consultants play an important role in protecting Oregon’s wetlands and waters. They work with applicants to delineate the boundaries of protected resources, submit delineation reports to DSL, and helping guide applicants through the removal-fill permitting process.

Oregon's Administrative Rules (OAR 141-085 and 141-090) require consultants meet certain standards when submitting delineation reports. Reports must:

Identify all wetlands and waters on the parcel.
Be prepared in accordance with the 1987 U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual, including its regional supplements for the arid west or western mountains and valleys, and any supporting technical or guidance documents issued by the USACE or DSL.
Meet the reporting requirements found in OAR 141-090-0030 and 0035.
