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.

The Corps is soliciting comments on the proposed work.
Beaver Slough Drainage District (BSDD)    
60196 Old Wagon Road
Coos Bay, OR 97420

Applicant’s Agent:
Coos Soil & Water Conservation District (SWCD)
Attention: Caley Sowers
379 North Adams Street
Coquille, OR 97423
Telephone: (541) 396-6879

Location: The project site is located west of the Coos Bay – Roseburg Highway, Oregon 42, between N Bank Lane and S Cedar Point Road, in Coquille, Coos County, Oregon. The site is in Sections 20, 27, 28, 29, 33, and 34, Township 27 South, Range 13 West. Latitude and Longitude: 43.198183° North, -124.245289° West.

Waterway: China Creek, tidal channels connected to China Creek and Beaver Slough, and wetlands adjacent to China Creek and Beaver Slough near the Coquille River between river mile (RM) 19.6 and RM 23. The project site floods seasonally and is known as Winter Lake. The Coquille River near the project site is a traditional navigable water that flows to the Pacific Ocean. The wetland boundaries and/or location of the ordinary high water mark (OHWM) 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 enhance hydrologic and ecological function for wetlands, fish, and wildlife, and improve agricultural operations in the Winter Lake area.

Project Description: The proposed project is the Winter Lake Phase III System Restoration and Maintenance Project. The applicant proposes to create an interior channel network with water control structures that mimic a natural channel network, maximize fish passage and forage opportunities, enhance fish and wildlife habitat, improve water quality, and provide drainage and irrigation for agricultural enterprises within a 1,383 acre site. The applicant would conduct work and discharge dredged and fill material below the OHWM of the waterbodies identified above and in wetlands to accomplish the project purpose. Permanent and temporary excavation and fill volumes total approximately 183,453 cubic yards (cy) of soil, rock, culvert infrastructure, and large wood which would occur in an area measuring approximately 149 acres.

Channel Excavation
In order to construct water channel networks that mimic historical conditions for juvenile salmonids, the applicant would excavate and redesign interior pasture channels including the reconstruction of 5.7 miles of existing channels and the creation of 14.1 miles of new channels with sloped banks that would be seeded with native vegetation. The channel network would be comprised of small, medium, and large channels ranging from 8 to 18 feet wide and 2.5 to 4 feet deep. The applicant would construct hydrologic depressions (bulbs) at the upper extent of the channels ranging in size from 0.7 to 1.9 acres and from 1.8 to 2.5 feet deep, for a total of approximately 18.56 acres. The total area excavated for channels from existing wetlands would be approximately 27.8 acres. Excavated materials would be thinspread to an average depth of 3 inches over a total of 87.2 acres.

Large Woody Debris Installation
The applicant would add 200 pieces of large woody debris measuring approximately (on average) 12 feet long and 15 inches in diameter at 12 locations to restore fish habitat.

Culvert Replacement
The applicant would replace 42 existing culverts with 38 new high-density polyethylene (HDPE) culverts appropriately sized for the tidal flow and fish passage with attached upgraded water control structures. At three locations the applicant may install corrugated metal pipe (CMP) culverts in lieu of HDPE culverts. The replacement culverts would measure 40 feet long with diameters ranging from 3 feet to 6 feet wide. The different culvert diameters are calculated appropriate for the tidal flow and fish passage at a given location. The applicant would permanently discharge up to 10 cy of 10 to14 in and 14 to 20 in diameter rock fill at the inlet and outlet of each culvert for scour protection.

Tidegate Installation
New tidegates would be attached to the culverts before installation. The tidegates would have muted regulators. Three types of tidegates are being considered: 1) side-hinged aluminum tidegates with a door brace for managing in the door-open position, 2) water control slide/knife gates operated manually through screw drive and wheel, or 3) other water control structures such as baffles or louvered gates.

Agricultural Features
In order to improve wetland function, water quality and agricultural operations, the applicant would reconstruct and raise 16 existing berms within their original footprint, add 15 additional culverts in channels for irrigation and cattle crossings, and create 9 cattle watering stations with rock fill pads. The cattle crossings and watering stations will support minimizing cattle entry into the channels. The 16 berms in need of repair vary in length from 75 feet to 600 feet. The applicant would permanently discharge approximately 5,323 cy of earthen fill material along approximately 3,498 linear feet of existing berm to achieve an approximate as-built design of 20 feet wide at the berm base, 12 feet wide at the top of the berm and a height of 6 feet. The applicant would install 15 HDPE or polyvinyl chloride (PVC) culverts with the possibility of three CMP culverts may also be installed; the culverts would measure 30 feet long and 4 feet in diameter. The applicant would discharge up to 8 cy of 6-inch diameter rock fill (Class 50 riprap) at the inlet and outlet of each culvert for scour protection. The rock fill pads would measure 20 feet wide by 20 feet long by 6 inches deep and would be comprised of 4-inch diameter rock.

The applicant proposes to install two vehicle access bridges at existing culvert locations: 1) the Messerle Farm Access bridge (southern location; see Figure 25b) would be 60 feet long by 12 feet wide with a 10 ft wide wooden deck constructed from railroad beams. The bridge would be supported by footers comprised of 3 inch shallow mat pad foundations with 3 inch pre-cast concrete, and up to 496 cy of riprap would be used to prevent scour at the bridge footings; 2) the second bridge would be installed at the Highway 42 access road channel crossing (northern location; see Figure 25b) and would be constructed with a concrete slab decking that would measure 28 feet, 10 inches long by 14 feet wide. This bridge would be supported by footers comprised of 1 foot of compacted 4-inch diameter gravel to support two feet of pre-cast concrete blocks, a 2 inch by 4-inch block of steel, ultra-high molecular weight polyethylene, or rough cut block of wood beneath the concrete slab. Bridge footers would permanently fill 320 square feet (0.0072 acre) of wetland. The applicant may opt to install a culvert instead of a bridge at the Highway 42 access road location, dependent on funding. If this design is chosen the applicant would install a CMP squash culvert that would measure 40 feet long by 86 inches wide by 61 inches high. The applicant would permanently discharge 10 cy of 10 to14 in diameter rock fill at the inlet and outlet of the culvert for scour protection.

Maintenance and Adaptive Management
The applicant has prepared a maintenance and adaptive management plan for a 20-year period after the initial project construction. The Corps will consider work under this plan to be part of the overall project. The plan includes culvert repair and replacement; flood gate repair and replacement estimated at approximately three per 5 year period; experimental design water control gates, screening, diversion hardware and infrastructure at five specific test locations in the first 10 year period; management of animal damage by filling holes; repair of berm slides/slumps; main canal sediment accumulation management (dredging) of no more than 400 cy (1,000 linear feet) in a 10 year period; interior canal sediment accumulation management (dredging) of no more than 100 cy (1,000 linear feet) in a 10 year period; vegetation management and removal from main and interior channels of up to 200 feet per year per 2,000 feet of channel; removal of blockages resulting from trees in the main and interior channels estimated at four small trees or willow branch removals per year; maintenance and replacement of off-channel watering systems to include 400 feet of trenching in a 5 year period in wetland pasture locations with pre-existing infrastructure; pasture and planting maintenance including disking, tilling, plowing, seeding, mowing, fertilizing, spraying of weeds, and plantings of trees and shrubs; alterations to interior channels as needed to enhance performance hydrologically, agriculturally, and for fish/wildlife habitat, estimated at 100 cy per year; and the thin spreading of spoils from excavations associated with the aforementioned activities at an average depth of 3 inches at the time of excavation on pasture areas where it will be fully stable; thin spreading of dredged material would occur in a total of approximately 7.4 acres of wetlands on-site. The applicant is seeking permit authorization for these activities.

The applicant would conduct the construction and also adaptive management work with conventional equipment such as excavators, farm machinery, and dump trucks.

Mitigation: The applicant proposes to avoid and minimize impacts from the project through the use of best management practices meant to minimize impacts to the aquatic ecosystem. The applicant would isolate work areas during construction, utilize erosion control devices, and would implement the project during a preferred in-water work period of July 1 through September 15 during the low incoming tide to minimize potential adverse effects to fisheries and water quality. In addition, the applicant would adhere to environmental conditions set forth by the Corps, the Oregon Department of Environmental Quality (DEQ), National Marine Fisheries Service (NMFS), and other respective agencies. 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: Thirty-one (31) drawings are attached and labeled Corps No. NWP-2014-92-4. 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.
