30 Day Notice

Interested parties are hereby notified that the U.S. Army Corps of Engineers, Portland District (Corps) and the Oregon Department of State Lands (DSL) are considering a proposal to establish a wetland mitigation bank (“Bank”) on up to 126 acres of a farmed parcel. The proposed bank site is located near Philomath, in Benton County, Oregon. The bank sponsor, Oregon Wetlands, LLC, proposes to restore, enhance, and create aquatic habitats including Willamette Valley wet prairie on Tax Lot 1300 in Township 12 South, Range 5 West, Sections 18 and 19 (latitude 44.522889° N, longitude 123.341000° W). A Prospectus describing the proposed bank has been received from the bank sponsors, and is now available for public review.

This Bank is being proposed by the Bank sponsors primarily as a means to meet the requirements for compensatory mitigation for projects which may be permitted by the Corps under the authority of Section 404 of the Clean Water Act and by the DSL in implementing the provisions of Oregon’s Removal-Fill Law (ORS 196.800 - 196.990) and according to Rules for Issuance and Enforcement of Removal and Fill Permits (OAR 141-85). The Bank sponsors would sell wetland credits to various parties to meet their obligations under the “no net loss of wetlands” policies of these federal and state regulations.

The proposed Bank will generate wetland credits by converting most of the farmed area to palustrine emergent, forested, scrub-shrub, flat and riverine wetlands. Hydrology would be restored or enhanced by removing drain tiles and drainage ditches, and constructing a mosaic of wetland depressions and low berms. The site would be designed to emphasize native wet prairie habitat by establishing native dominated plant communities. The total project size and wetland classes will be determined prior to Bank approval.

A delineation report will be submitted to the regulatory agencies for review to verify the extent of existing wetlands and hydric soils. This information will be used to determine how much of the area qualifies for restoration or enhancement credit ratios.

The proposed service area, which is the area within which the mitigation credits generated by the Bank may be used, consists of portions of the Upper Willamette 4th Field Hydrologic Unit 17090003 as well as portions of the Middle Fork Willamette (HUC 17090001), Coast Fork Willamette (HUC 17090002), and McKenzie (HUC 17090004) watersheds. This service area includes the urbanizing areas of Millersburg, Albany, Tangent, Philomath, Corvallis, Brownsville, Tangent, Junction City, Veneta, Halsey, and Eugene, as well as smaller communities within these watersheds. 

Comments received in response to this notice will be provided to the Bank sponsor and to the federal, state, and local agencies represented on the mitigation bank interagency review team. This team will work with the bank sponsors to create a detailed bank instrument and legal agreement that will specify the ecological goals of the project, grading and planting plans, monitoring, maintenance, and the number and schedule of wetland credits to be made available when performance standards have been met.

The prospectus, which outlines the conceptual plan for this bank, is available for inspection at the Corps and the DSL at the addresses given below. It has been posted along with Benton County Removal-Fill permit applications on the DSL website: www.statelandsonline.com/. Comments on this proposed mitigation bank may be submitted to either the Corps via e-mail or the DSL online comment link or to either address below. Comments should be received no later than April 6, 2018.
