Portland, Oregon 97201
Telephone: (503) 499-0392
Location: The project site is located at SW Tualatin-Sherwood Road between SW Teton Avenue and SW Olds Place in Tualatin and Sherwood, Washington County, Oregon. The site is in Sections 22, 23, 26, 27, and 28, Township 2 South, Range 1 West. Latitude and Longitude: Begin 45.378204 North, 122.779805 West; End 45.367831 North, 122.833203 West
Waterway: The project site includes Stream A, Stream B, Wetland A, Wetland B, Ditch D-1, Ditch D-2, Ditch D-3, Ditch D-4, Ditch D-5, Ditch D-6, Ditch D-2-1, Ditch D-2-3, Ditch D-2-4, Ditch D-2-5, Ditch D-2-6a, Water Quality (WQ) Swale A, and Swale B. The wetland boundaries and location of the ordinary high water mark shown on the project drawings have not yet been verified by the Corps. If the Corps determines the boundaries of the wetland/waters are substantially inaccurate a new public notice may be published.
Project Purpose: The applicant’s stated purpose is to alleviate traffic and make improvements along the corridor by incorporating bus pull-outs, turn lanes, and multiple-use paths.
Project Description: The proposed project is the SW Tualatin-Sherwood Road Improvements Project. The project includes the discharge of up to 1,816 cubic yards of fill over 0.35 acre of wetlands and 1,661 cubic yards below the ordinary high water mark of 0.30 acre of waters. The project corridor is approximately 2.9 miles in length. The project would widen the segment of Tualatin-Sherwood Road from three to five lanes (two travel lanes in each direction and a center turn lane) with multi-use path accommodations and bus pull-outs. The typical section would include two 12-foot wide multi-use paths, two 4.5-foot curb and planter strips, two 14-foot wide outside travel lanes, two 11-foot inside travel lanes, and a 13-foot wide median. Additional turn lanes would be included at several intersections. Work within active channels would be completed during the July 15 through September 30 in-water work period.
The project would install a new stormwater system along the length of the corridor and add three water quality ponds for treatment and detention. The water quality treatment is proposed to treat 100% of the contributing impervious area. The project would add a net increase of 18.65 acres to the on-site contributing impervious surface. The proposed contributing impervious area is 46.66 acres. The proposed water quality facilities are three biofiltration ponds that would treat the entire 44.90 acres of the contributing impervious area, and the remaining area would be treated in an existing pond.
Due to the widening of the roadway, the project would result in the placement of permanent fill in Wetland A, Wetland B, Stream A, WQ Swale A, Swale B, and several roadside ditches. The fill material would be primarily topsoil and include portions of aggregate base, asphalt, and concrete for the construction of multi-use paths or concrete sidewalks. WQ Swale A would be filled entirely to accommodate the widening and multi-use path on the north side. Its inlet and outlet would be filled and no longer functional. A stormwater quality pond (Proposed Water Quality Pond 1) would be installed south of SW Tualatin-Sherwood Road, east of Rock Creek, impacting Wetland A. The second stormwater pond would be installed west of Stream B. This pond would discharge to Stream B but would not require any removal or fill activities. The third stormwater pond would also not require any removal or fill activities. Stream A would be piped into an inlet 24 feet south from the existing south culvert inlet. The proposed ditch inlet would flow into the storm system to receive treatment prior to discharging into Hedges Creek.
Mitigation: The applicant proposes to avoid and minimize impacts from the project by incorporating standard best management practices (BMPs), marking waters and wetlands prior to construction, and using stream diversion piping. Geotextile fabric would be laid under crushed rock at wetland and stream crossings to limit impacts from construction vehicle movement and would be removed when construction is completed. Standard BMPs to prevent erosion and runoff into the wetlands and waters include, but are not limited to, silt fencing, compost socks, straw wattles, stockpile cover, and slope erosion control. The applicant proposes to purchase 0.97 palustrine emergent wetland credits from the Tualatin Valley Environmental Mitigation Bank or Butler Mitigation Bank and 0.30 riverine waters credits from the Half Mile Lane In-Lieu Fee program to offset losses of waters of the U.S. that may result from the proposed project. The Corps will determine the type and amount of compensatory mitigation necessary to offset environmental losses from the proposed project.
Drawings: Fourteen (14) drawings are attached and labeled Corps No. NWP-2020-208. 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 http://www.nwp.usace.army.mil/Missions/Regulatory and select Regulatory Public Notices from the list of Regulatory pages.
Additional Information: The project would coordinate with the Willamette Water Supply Program (WWSP) pipeline installation to facilitate construction timelines and cooperatively manage the overlapping project areas. The WWSP is a partnership between Tualatin Valley Water District and the City of Hillsboro to build an additional regional water supply system in Washington County (Corps # NWP-2015-41) and will be constructing a 66-inch drinking water pipeline in conjunction with the roadway improvements.
Authority: The proposed project will be evaluated under the following:
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 source of the fill material would be sourced by the contractor from Washington County approved sites that meet the material specifications of the project.
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 has initiated 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 has initiated 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 a historic properties investigation has been conducted and another is currently being completed within the permit area. Currently, no sites determined eligible for or listed on the National Register of Historic Places were found to exist within the permit area.
This notice has been provided to the State Historic Preservation Office (SHPO), interested Native American Indian Tribes, and other interested parties.
