Mr. Michael LaDouceur 
P.O. 2946
Portland, Oregon  97208-2946

Applicant: Suttle Road Moorage, LLC, Mr. David Blasen, PO Box 591, La Center, Washington 98629

 The proposed project is located at Suttle Road Moorage at 4101 North Marine Drive, in Portland, Multnomah County, Oregon

Waterway: The dredging will be located in the Oregon Slough portion of the Columbia River at River Mile 2.6 (latitude 45.6166, longitude – 122.7091) and the disposal site will be located north of the dredging at latitude 45.6187, longitude -122.7093.  

Project Description: The project would include removing accumulated sediment from an area measuring 400 feet by 180 feet and be maintained at a depth of -6 Columbia River Datum (CRD).  A total of up to 4,500 cubic yards of sand and silt would be removed over a 5-year period.  Removal would be accomplished by either clamshell removal or by a hydraulic suction dredge.  The disposal area is approximately 600 feet by 200 feet in dimensions and would increase the bottom elevation within the disposal location by approximately one foot.  The applicant has proposed the following two disposal methods:  If a clam shell is used, the sediment will be placed in a barge and transported to the disposal area and if a hydraulic suction dredge is used, a floating pipe will be used to transport the sediment to the disposal location.  All work would be conducted during the Oregon Department of Fish and Wildlife in-water work window of November 1st to February 28th.  

Sediment sampling was completed for the proposed dredge area.  The samples were analyzed and the data reviewed by the Portland Sediment Evaluation Team (PSET) to determine if the dredged sediment meets standards for in-water disposal.  The PSET review determined that the sediment is suitable for in-water disposal.  

Mitigation: The applicant has provided a statement that impacts will be temporary and no mitigation should be required.  If a permit is issued, the Corps will determine what is appropriate and practicable compensatory mitigation.  The amount of compensatory mitigation required shall be commensurate with the anticipated impacts of the project.

Purpose: To maintain boating access and appropriate clearances for houseboats.  

Drawing(s): Six (6) drawings are attached and labeled Corps No. NWP-2014-347

Additional Information: Additional information may be obtained from Mr. Michael LaDouceur, Project Manager, U.S. Army Corps of Engineers at (503) 808-4337, or by e-mail at michael.a.ladouceur@usace.army.mil.

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

Water Quality Certification:
 A permit for the described work will not be issued until certification, as required under Section 401 of the Clean Water Act (P.L. 95 217), has been received or is waived from the certifying state.  Attached is the state's notice advertising the request for certification.

Section 404(b)(1) Evaluation: The impact of the activity on the public interest will be evaluated in accordance with the Environmental Protection Agency guidelines pursuant to Section 404(b)(1) of the Clean Water Act.

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.

Endangered Species:
 Preliminary determinations indicate that the described activity may affect an endangered or threatened species or its critical habitat.  Consultation under Section 7 of the Endangered Species Act of 1973 (87 Stat. 844) will be initiated.  A permit for the proposed activity will not be issued until the consultation process is completed.

Cultural Resources: An initial evaluation of the proposed project area indicates that an initial evaluation of the proposed project area 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 State Historic Preservation Office (SHPO), interested Native American Indian 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 on page 1 of this notice) to assist in a complete evaluation of potential effects.

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 described activity 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.

The Corps is soliciting comments from the public; Federal, state, and local agencies and officials; Indian Tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity.  Any comments received will be considered by the Corps to determine whether to issue, modify, condition or deny a permit for this proposal.  To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above.  Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act.  Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity.

Additional Requirements:
 State law requires that leases, easements, or permits be obtained for certain works or activity in the described waters.  These State requirements must be met where applicable, and a Department of the Army permit must be obtained before any work within the applicable Statutory Authority previously indicated may be accomplished.  Other local governmental agencies may also have ordinances or requirements, which must be satisfied before the work is accomplished.
