STATEMENT OF WORK

Cackler Marsh Fish Passage

Baskett Slough NWR June 2022

1. GENERAL

The US Fish and Wildlife Service (FWS) has a request for A-E Services to address the lack of adequate fish passage at Cackler Marsh. The proposed design will undergo fish passage review by Oregon department of Fish and Wildlife (ODFW) as part of the permitting process.

A. Work will include but not necessarily limited to creating new berms, stream channels, and water control structures.

B. Refer to Federal Acquisition Regulation (FAR) Clause 52.236-22, the Estimated Cost of Construction contract price for the project described is $800,000.00. When preparing the Architect-Engineer Fee Estimate, the design will be based on 6 percent of the estimated cost of construction contract price ($48,000). Due to FAR, the Simplified Acquisition Threshold (SAT) is $250,000. If at any time the A-E determines their necessary effort exceeds the SAT, the A-E will provide recommendations on how to de-scope the project.

C. The A-E shall promptly notify the COR and CO if it finds that the project being designed will exceed or is likely to exceed the construction funding limitations and it is unable to design a usable facility or project within these limitations. Upon notification, the COR and CO will review the A-E’s estimated cost of construction to determine the appropriate action(s) (e.g.

de-scoping; creation of optional tasks).

D. Performance Period: 150 days from NTP

2. SCOPE OF WORK

Services for planning and design will include, but not necessarily be limited to the tasks listed below. All deliverables shall be submitted to the USFWS using e-mail and an FTP site provided by the A-E.

Refuge staff will likely implement the majority of the earth moving in-house, which is a consideration in terms of construction funding and associated design. The refuge has access to self-propelled scrapers, dump trucks, excavator, dozers, and other related equipment.

FWS will provide wetland and topo data of the project area.

A. Project Description

Baskett Slough National Wildlife Refuge is located in northwestern Oregon, approximately 10 miles west of Salem. Situated in open farmland with the Willamette Valley and the Cascade Range to the west, elevations range from 185 to 414 feet MSL. The refuge, approximately 4 square miles, operates as a series of constructed wetlands and serves as a stopping point for hundreds of waterfowl that use the wetlands seasonally during annual migrations.

In summer 2021 a large stream and wetland restoration project in Dusky Marsh addressed a

Baskett Slough NWR, Cackler Marsh Fish Passage Page 2 of 6 lack of fish passage that had threatened water rights within the 98-acre impoundment. The restoration project removed a berm that dammed Baskett Slough, a perennial waterway, and restored ¾ mile of naturalized meandering stream that was formerly a channelized agricultural ditch.

Directly upstream of this restoration project are 4 more impoundments that dam Baskett Slough, all creating fish passage barriers. This project will restore Cackler Marsh with stream and wetland improvements to address fish barriers.

Prior to the construction of the impoundments in the late 1990’s, Baskett Slough was straightened and channelized. Currently, there is approximately 3 miles of dammed, channelized stream within these 4 impoundments that total 364 acres.

B. Cackler Fish Passage Design The refuge’s long-term goal is to maximize off-channel wetland acreage via set-back berms like at Dusky Marsh. Cackler is a large 200-acre wetland and the flat topography may be conducive to this approach based on if the cost/benefit is enough to justify the earthwork.

Refuge staff have developed two conceptual design alternatives to address the lack of fish passage within Cackler Marsh. Like Dusky, the Cackler project aims to remove the water control structure that acts as the passage barrier, restore a meandering naturalized stream, and construct new berms that allow the emergent marsh habitat to be off channel. However, the Cackler berm also serves as a primary access road for refuge staff and cooperative farmers.

Baskett Slough NWR, Cackler Marsh Fish Passage Page 3 of 6

Therefore, we intend to maintain all or a portion of that berm to provide access for vehicles and heavy farm equipment like tractors and combines.

Both alternatives have several common features. First, both will fill all, or part, of the current

1.0 miles of channelized ditch, which is not nearly as deep as the Dusky ditch was, at approximately 1.5’ deep, or below pond bottom, on average. Then, each alternative will excavate approximately 6210’, or 1.18 miles, of meandering stream channel. Two off channel wetlands will be constructed, one on the north side of the stream (110 ac) and one on the south (20 ac). The wetlands will require berms to be constructed of approximately 5050’ (.96 miles) for the north wetland and 1200’ (.22 miles) to the south. Berm heights will be approximately the same height and profile as the Dusky berm (i.e., ~3’ tall, 8’ top width, 8:1 side slopes). The northern wetland will need independent water delivery from Taverners marsh upstream, which will require installation of a screw gate that goes under Coville Rd.

The primary difference between the two alternatives relates to the stream crossing and passage barrier removal in the Cackler berm. Even though we seek to retain access across Cackler berm, we realize that significant quantities of earthen material will be necessary to construct the new berms. Moreover, a primary goal within the stream is to promote riverine, aquatic, and floodplain processes to the extent practical, while considering cost as a limiting factor.

Minimally we aim to remove the existing corrugated metal pipe water control structure and replace it with an approximate 40’ wide box culvert. The restored stream channel is approximately 35-40’ wide, therefore the box culvert should be adequate to convey flow. On the other end of the spectrum, we’d like to explore constructing a longer span beam bridge. The span could range from 100 to 400’, allowing for that earthen material to be used in the new off channel berms. Moreover, a wider floodplain span could allow for over-bank flooding and other floodplain processes. Regardless, significant borrow areas will be required to construct the new berms. Based on NRCS web soil surveys that show hydric soil locations we have identified one borrow site. An additional site for the south wetland can be identified in further design.

The 2021 Dusky fish passage project provided independent water delivery from Cackler marsh to the new Dusky marsh by installing a screw gate that connects the wetland units and we would like to maintain delivery ability in some fashion. Currently we can impound water in Cackler at sufficient depths to open the gate and deliver water directly to Dusky. If we remove the water control structure, we will likely lose the ability to raise the water level high enough for delivery as currently constructed. We would like the Cackler design to explore options to maintain water delivery capability. It seems that we would need to excavate a side stream channel that connects the newly restored Baskett Slough stream to the screw gate, although water depths may not be sufficient to deliver. The design may need to explore lowering the screw gate, moving the screw gate, or installing some sort of small pump. We aim to minimize the amount of infrastructure to maintain and limit the need to install fish screens.

C. Permitting

Like the Dusky Marsh Fish Passage Project, the refuge is seeking design and permitting assistance for Cackler marsh. The conceptual design shall provide the framework to execute a grading plan, estimate quantities, and produce a plan set that will facilitate compliance requirements. The refuge will perform most of the permitting requirements, as detailed in the

Baskett Slough NWR, Cackler Marsh Fish Passage Page 4 of 6 specific task items below.

The refuge is specifically seeking assistance with removal fill quantity tables and ESCP plans/requirements/representation. We aim to construct Cackler marsh in summer 2024.
