Permit Application Public Notices

The United States Congress authorizes the U.S. Army Corps of Engineers to regulate activities that may impact wetlands and waters of the United States. This authority is granted and defined under Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Federal Water Pollution Control Act Amendments of 1972, also known as the Clean Water Act.

Public involvement is a key element of the Corps’ permit review process. During an application review, the Corps considers the views of other federal, state and local agencies, Native American tribes, interest groups, and the general public. The results of this careful public interest review are fair and equitable decisions that allow reasonable use of private property, infrastructure development, and growth of the economy, while offsetting the authorized impacts to the waters of the United States.

30-Day Notice

Interested parties are hereby notified the U.S. Army Corps of Engineers, Portland District (Corps) has received an application for a Department of the Army permit for certain work in waters of the United States, as described below and shown on the attached plans. The Corps is soliciting comments on the proposed work.

Applicant’s Agent:     Stillwater Sciences
                                       Attention: Kim Gould
                                       108 NW 9th Ave
                                       Portland, Oregon 97209
                                       Telephone: (503) 267-9006

Location: The project site is located at river mile 13, located at 3121 SW Moody Avenue, Multnomah County, Oregon. The site is in Sections 10 and 3, Township 1  South, Range 1 East.  Latitude and Longitude:  45.4996 North, 122.6654 West

Waterway: The work is located in the Willamette River. The location of the ordinary high water mark (OHWM) shown on the project drawings has not yet been verified by the Corps. If the Corps determines the boundaries of the waters are substantially inaccurate a new public notice may be published.

Project Purpose: The applicant’s stated purpose is to stabilize the riverbank over the remedial cap in targeted areas of erosion in order to protect public and environmental health and habitat functions. 

Project Description: The proposed project is the Zidell Riverbank Toe Erosion Control Maintenance project. The project would permanently place 2,482 cubic yards of clean fill over 27,505 square feet (0.63 ac) of riverbank below the ordinary high water mark for bank stabilization. The project would temporarily place 62 cubic yards of material in 1,000 square feet of wetland to construct a temporary access road to access the project area. 

The work is divided into three reaches as follows: The downstream reach (Repair Area F, G, and H), the slipway reach corner (Repair Area E), and the bridge shade repair area. 

The downstream reach repair would be applied between elevations +10 feet and +18 feet OHW. Debris would be removed, vegetation pruned back, and the bank will be sloped by hand. Geosynthetic filter fabric would be placed along the horizontal and vertical faces of the erosion area. Gravel 1.5 inch minus rock aggregate would be placed in a 3 to 6-inch thick layer around the established vegetation. Type D rock armor (4-inch minus crushed rock) would be placed around the vegetation in a 1- to 2-foot thick layer over the lower gravel layer. The interstitial spaces of rock armor would be filled with rounded gravel for habitat. The slipway reach corner repair would place rock armor consistent with the current materials at the site. A 2- to 3-foot thick layer of Type D rock armor would be placed on top of geosynthetic filter fabric. The bridge shade repair area would place fill above the OHWM and would utilize the same methods as the downstream reach repair.

Construction would occur at low river stages. The materials would be sourced from a local commercial quarry and delivered to the site by truck. At the staging area, materials would be stockpiled and loaded into tracked transport vehicles with dump beds. Material would be delivered to the site via the temporary access road. The temporary access road would be fully removed and reclaimed after the completion of construction.

Vegetation in the work area would not be cleared but would be pruned back in place. The pruned materials would be kept onsite to allow for replanting along the bank as part of the reclamation of the construction areas. After pruning, excavation of existing material would occur to facilitate slope construction. All excavation would be completed by hand. Filter fabric and rock would be hand placed at the site. Live stakes harvested from the site and will be replanted onsite in the work areas.

All hand-cut soils and gravel would be distributed immediately adjacent to the repair area or incorporated into the fill. There would be no export of soil from the site or discharge into the water.

Mitigation: The applicant proposes to avoid and minimize impacts from the project by using best management practices when placing fill at the site. These include, but are not limited to, all work being done in dry conditions, when the river stage allows workers to stage then hand-place materials, no deliveries will be occur from barges, all rock will be placed by hand in the areas planted with woody vegetation, all imported material will be clean and free of weeds, and all equipment will be staged, fueled, and maintained from above the top of bank. The applicant did not propose compensatory mitigation in the permit application. The Corps will determine the type and amount of compensatory mitigation necessary to offset environmental losses from the proposed project.

Drawings:  Thirteen (13) drawings are attached and labeled Corps No. NWP-2007-962-4. Copies of this public notice, which have been mailed or otherwise physically distributed, feature project drawings in black and white. The electronic version features those drawings in color, which we think more accurately illustrates the proposed project. To access the electronic version of this public notice, go to the Portland District Regulatory website at and select Regulatory Public Notices from the list of Regulatory pages.

Additional Information: The work is proposed to be completed during the in water work window of July 1 to October 31. The applicant intends to request an in water work window variance if low water conditions allow for work outside of the in-water work window.

Authority: The proposed project will be evaluated under the following:

    Section 10, Rivers and Harbors Act 1899 (33 U.S.C. 403), for work in or affecting navigable waters of the United States.

    Section 404, Clean Water Act (33 U.S.C. 1344), for discharge of dredged or fill material into waters of the United States.

Clean Water Act Section 404(b)(1) Guidelines: The described discharge will be evaluated for compliance with guidelines promulgated by the U.S. Environmental Protection Agency under authority of Section 404(b)(1) of the Clean Water Act. The 404(b)(1) Guidelines are the substantive criteria used in evaluating discharges of dredged or fill material into waters of the United States. The Corps will evaluate the fill material source (i.e., borrow site) prior to finalizing a permit decision.

Water Quality Certification: Section 401 of the Clean Water Act (33 U.S.C. 1341) requires applicants to obtain a water quality certification for proposed discharges into waters of the United States. A permit for the described work will not be issued until certification has been issued or is waived from the certifying state. Attached is the state's notice for a water quality certification.

Endangered Species: Section 7 of the Endangered Species Act (ESA) (16 U.S.C. 1536) requires federal agencies to consult with the National Marine Fisheries Service (NMFS) and/or U.S. Fish and Wildlife Service (USFWS) on all actions that may affect a species listed (or proposed for listing) under the ESA as threatened or endangered or that may adversely modify designated critical habitat. The Corps’ preliminary review indicates the described activity may affect an endangered or threatened species or designated critical habitat. The Corps will initiate consultation under Section 7 of the ESA. The Corps will complete the required consultation prior to finalizing a permit decision.

Essential Fish Habitat: Section 305(b)(2) of the Magnuson-Stevens Fishery Conservation and Management Act (MSA) as amended (16 U.S.C. 1855), requires Federal agencies to consult with the NMFS on all actions, or proposed actions, permitted, funded, or undertaken by the agency, that may adversely affect Essential Fish Habitat (EFH). The Corps’ preliminary review indicates the described activity would adversely affect EFH at the project location or in the vicinity. The Corps will initiate consultation under Section 305(b)(2) of the MSA. The Corps will complete the required consultation prior to finalizing a permit decision.

Historic Properties/Cultural Resources: Section 106 of the National Historic Preservation Act of 1966, as amended (54 U.S.C. 306108), requires Federal agencies to consult with the appropriate State and/or Tribal Historic Preservation Officer to take into account the effects of actions they undertake or permit on historic properties listed in or eligible for listing in the National Register of Historic Places. The Corps’ preliminary review indicates to the best of our knowledge, the described activity is not located on property registered or eligible for registration in the latest published version of the National Register of Historic Places. At this time the Corps is unaware of any cultural resource surveys of the project area. 

This notice has been provided to the Oregon State Historic Preservation Office, interested Native American Tribes, and other interested parties. If you have information pertaining to cultural resources within the permit area, please provide this information to the Corps’ project manager identified at the end of this notice to assist in a complete evaluation of potential effects.

State and Local Authorizations: The applicant will be applying for the following additional governmental authorizations for the project: Oregon Department of State Lands and Oregon Department of Environmental Quality.

Public Hearing: Any person may request in writing within the comment period specified in this notice that a public hearing be held to consider this application. Requests for public hearings shall state with particularity the reasons for holding a public hearing.

Evaluation: The decision whether to issue a permit will be based on an evaluation of the probable impact, including cumulative impacts, of the described activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit, which reasonably may be expected to accrue from the described activity, must be balanced against its reasonably foreseeable detriments. All factors, which may be relevant to the proposal will be considered including the cumulative effects thereof; among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, consideration of property ownership and, in general, the needs and welfare of the people.
