| | A | 165 | Produce Environmental Compliance Documentation | Environmental Compliance Clearance: Habitat Restoration & Enhancement Projects | Work with the BPA EC lead to ensure that work tasks and project actions developed throughout the current (and prior) contract will meet permitting and environmental compliance requirements. For example, provide needed information and support to ECF for ESA consultations (US Fish & Wildlife Service or NOAA Fisheries) and Cultural Resource reviews and concurrences (e.g., State [SHPO] & Tribal [THPO]) for work that is planned for the contract period, prior to beginning any of the work activities.
Coordinate with the BPA Environmental Specialist (EC-Lead) to obtain NEPA, ESA, cultural resources, and other environmental compliance clearances required to implement: (a) upland projects (direct seed, upland erosion and sediment control measures, cropland-to-grassland conversions); (b) water developments; (c) riparian restoration projects (fencing, planting, and grazing BMPs); and (d) in-channel construction activities that are planned for implementation in 2018-2021, including materials or equipment staging areas and construction access points -- and as habitat features and implementation logistics and schedules become more firmly documented through preliminary planning and design details, final design adjustments, and site planning.
On-the-ground work cannot begin until environmental compliance and cultural resource clearance has been received from the EC-Lead. | | |
| | B | 119 | Manage and Administer Projects | Project implementation management and contract administration: Watershed Habitat Program | This work element includes the duties associated with watershed-based program management, the identification and implementation of priority riparian and floodplain restoration projects, the support of improved upland management practices, and the general administrative requirements of the contract. These include: implementation of the current contract SOW, managing a budget, and satisfying BPA contracting requirements, including preparing and submitting invoices and next year's statement of work and budget, maintaining a property inventory, confirming accrual estimates, accounting for cost-share, etc.
It may include supervising and training staff, and providing professional development; addressing issues presented by various user groups and county, state and federal entities; maintaining licenses/training requirements, and responding to and/or addressing local concerns and unforeseen opportunities and issues as they arise. | | |
| | C | 114 | Identify and Select Projects | Implementation Planning: Identify, prioritize and select projects for habitat improvement | The Asotin County Conservation District (ACCD) will work with federal, state and local partner agencies and local landowners to develop strategic project selection and implementation planning for all of the smaller watersheds in Asotin County. This process will not replicate previous planning efforts including the Asotin Subbasin plan, the sub-regional Snake River Salmon Recovery Plan, WRIA 35 Watershed Plan, and the Asotin Creek Model Watershed Plan; but will synthesize critical information from these plans to strategically identify prioritized locations and restoration activities required to recover and enhance aquatic habitats for ESA-listed fish species.
Strategic planning will prioritize the appropriate types of restoration activities in priority locations to address key limiting factors and provide the transition from the current model of opportunistic restoration and enhancement to focused restoration of key reaches containing critical ESA habitat and facilitate collaborative, focused, and value added restoration projects. The planning that will be done based on the geomorphic assessments and conceptual restoration plans in Asotin County -- data and maps related to limiting factors, life history requirements, biologically significant reaches, habitat restoration opportunities and priorities, conceptual restoration templates consistent with local geomorphology, and a scoring and ranking matrix that will be collectively evaluated by local and regional experts, and the residents of the watersheds and restoration practitioners.
It also includes: (a) directing the planning and implementation of prioritized habitat enhancement projects in the watershed area by working proactively with private landowners to identify priority habitat enhancement projects and develop cost-share applications (upland BMPs, riparian planting, riparian fencing, grazing BMPs, etc.); and (b) directing the planning and implementation of priority riparian restoration and floodplain habitat enhancement projects in the watershed, and (c) adaptively managing implementation actions. | Steelhead (O. mykiss) - Snake River DPS (Threatened) | Chinook (O. tshawytscha) - Snake River Spring/Summer ESU (Threatened), Trout, Bull (S. confluentus) (Threatened) |
| | D | 99 | Outreach and Education | Enhance participation in the Watershed Habitat Enhancement Program | Overall accomplishment reporting regarding each of the following specific outreach and education activities is to be included in the annual report:
A) Monthly newsletters updates are produced each year and are sent electronically to about 250 recipients; a limited number of paper copies of outreach materials will continue to be available upon request. Newsletters provide landowners with information about activities taking place in the watershed, upcoming events, conservation practices, cost-share opportunities, and other important topics. ACCD will continue to transition to a electronic newsletter format, and additional mailing lists, to better inform cooperators and the public of activities that are in progress or opportunities that are available. Project signs have been and will be posted at various sites to promote the conservation practices that landowners have voluntarily implemented. For an overall newsletter description, see: www.asotincd.net/programs/information and education.
B) Continued support for Salmon in the Classroom Programs within the elementary schools in Asotin County. The Salmon in the Classroom project provides salmon education to Asotin County students (see www.asotincd.net/programs/information and education for an overall project description). Current District efforts reach 20 - 50 students in each of eight classroom; the District provides rearing tanks and technical support to raise rainbow trout for release in approved ponds in late May or early June. Students learn about the salmon life-cycle, habitat requirements, and water quality standards - all in the context of how and why it is important to protect the environment. Goal is to reach all students in the District (six schools).
C) The District provides a youth workshop on water quality. Students learn about the importance of water quality for fish, wildlife, and humans and the impacts human activity can have on natural resources. Students may also be involved in helping with tree plantings and monitoring water quality.
D) Tours of completed and on-going projects and workshops (approximately 50 people) are conducted to showcase conservation activities implemented in the watershed. | | |

| | I | 175 | Produce Design | Produce design for Post-Assisted Log Structures (Kelly Creek PA 45): elevate water table, increase wetted-margin, support native habitat plantings | Approximately 70 structures, Post Assisted Log Structures (PALS) and Beaver Dam Analogs (BDAs) will be installed to begin the process of retaining sediment and water in the stream bed channel in Kelly Creek.
These structures are expected to reduce stream velocities, induce lateral channel migration, promote ponding, cause rapid aggradation of the incised streambed, and allow for riparian and adjacent floodplain vegetation to become better established through improved growth and vigor.
The contractor will supervise and manage the implementation of the Project design. Project construction will be completed by a WCC work crew through an inter-agency agreement with the WA Dept of Ecology.
Project staff is encouraged to initiate pre-construction activities late in this contract period; construction management will continue contemporaneously with pre-construction activities: to organize construction planning and to consider implementation logistics and likely construction requirements prior to the scheduled build-period of the designs under development or near completion.
The contractor will supervise and manage work-site preparation, access point development, material acquisitions, staging for implementation, and the implementation of the components and adjustments or maintenance of the PALS project designs. Delayed or additional phases of the overall planned project construction activities may extend into the subsequent (FY24) contract period and be completed during the Summer 2024 work window.
1) Develop and review public bid documents (if applicable) for solicitation of construction-related sub-contractor contracts; review bid submittals, and select contractor(s);
2) Where feasible and as clearances are obtained, prepare projected construction access points and material or equipment staging areas, in anticipation of the implementation of the habitat restoration design during the Summer of 2023.
3) Source and plan the acquisition of construction materials needed for habitat features and restoration actions. Secure and, as necessary, transport posts, trees (small wood), racking and other construction materials to pre-arranged storage locations to support construction needs and future implementation planning; and
4) Provide field engineering and construction inspections to ensure site is developed and structures are being built to design standards. Review construction notes and submit as-built drawing following construction.
Construction management will be provided for both preliminary activities, during construction preparation, and for the installation of design features, as required under HIP EC approval.
Background: Large and small woody debris will be used in the stream channel and secured in place by wood fence posts driven into the streambed. Typically, each individual structure may use 2-4 pieces of wood (6-10' long and 4-20" diameter), and small woody debris for additional complexity, secured by 6-8' wooden posts. Structures are generally spaced approximately 60-75' apart, depending on existing habitat conditions and desired geomorphic outcomes and will be installed as planned in the design report that was developed for this project. All support structures are installed using an hydraulic post-pounder; wood pieces and racking are placed by hand.
Purpose: Installation of PALS is intended to help restore a more ecologically-based stream channel process that will increase the availability and duration of water in the wetted-margin, restore proper riparian structure and complexity, and improve floodplain function and connectivity. The objectives for each structure are to: 1) constrict flow to increase scouring and ponding or pool formation; 2) back-up water behind the structures to encourage hyporheic exchange, localized wetted riparian margins, and recurrent floodplain inundations; and 3) promote groundwater retention and an elevated water table in the areas immediately adjacent to and downstream of the structures to support native vegetation plantings used for wildlife habitat.

| | P | 184 | Install Fish Passage Structure | Fish Passage Box Culvert on Cougar Creek | The Cougar Creek culvert is currently a fish passage barrier where Cougar Creek flows under the Grande Ronde River Road, posing an imminent threat to anadromous fish (steelhead), and limiting their access to at least 2.25 miles of potential rearing and spawning habitat upstream of the culvert. This barrier will be replaced with a three-sided concrete box culvert. Cougar Creek flows directly into the Grande Ronde River approximately 150 feet below the barrier. The current culvert was identified in 2008 by the Walla Walla Community College Road Crossing Barrier Assessment as a barrier, and was included in a WDFW Inventory Assessment in 2016. Cougar Creek has been identified as a priority protection reach for steelhead, its benefit to the life history diversity within the Lower Grande Ronde steelhead population is considered to be significant.
ACCD developed this project in conjunction with Asotin County and WDFW. The design package is being developed with RCO SRFB and BPA funds and the project construction will be a partnership between RCO FBRB, RCO SRFB and BPA to remove the fish passage barrier and reconnect critical habitat. | Steelhead (O. mykiss) - Snake River DPS (Threatened) | |
| | Q | 47 | Plant Vegetation | Riparian Planting (Tenmile PA 65, 66, 67): Habitat trees and shrubs | Riparian or floodplain planting: trees and shrubs planted in the Spring (or Fall) to encourage or jumpstart new vegetation, or support the existing naturally-occurring vegetative community, in stream channel areas and the floodplain zone. The overarching implementation strategy is the establishment and support of riparian plantings that serve in the longterm to provide shade and reduce temperatures, and contribute to proper channel structure, floodplain connectivity, and riparian habitat function.
Enhancing and restoring instream habitats throughout identified project areas will be accomplished through a variety of treatment actions in the main channel, along the banks, and within the floodplain; the associated treatment of riparian areas is expected to induce naturally occurring repair, restoration, and recovery of both floodplain and riparian zone function and processes. Plantings are for shade, to encourage floodplain development and connection to riparian processes, and to support proper habitat function.
Note: Specific landowner commitment under development, and pending Board approval. See additional requirements and specifications in the Contract Summary narrative [Management Considerations, Sec.4]. The emphasis in these additional planting opportunities should continue to be in the riparian zone. | Steelhead (O. mykiss) - Snake River DPS (Threatened) | |
