and (2) assessment of feasibility of natural storage projects on Whatcom Land Trust and other private properties within the Black Slough, Landingstrip Creek, and Rothenbuhler Creek wetland complexes. Project Long Description The Nooksack watershed represents a high priority watershed for streamflow constraints in Washington State. This proposal is a collaborative approach put forward by the WRIA 1 Watershed Management Board to design and implement natural storage solutions with broad support across the members of the Board. The work will be collaboratively implemented by Whatcom County and the Nooksack Indian Tribe. Changing climate conditions, including warmer temperatures and lower precipitation levels in the summer, are causing glaciers to recede, winter precipitation falling as rain rather than snow and droughts to become more frequent and intense. As a result, the WRIA 1 watershed faces water availability, water quality, and salmon recovery challenges. Recent modeling and analysis show that a changing climate will continue to cause significant impacts to streamflows in the next 50 years (WRIA 1 Regional Water Supply Plan Phase 2 project and modeling completed by Western Washington University, Bob Mitchell, 04/26/2023). The Nooksack River and its forks support populations of nine salmonid species, three of which are listed as threatened under the Endangered Species Act: Chinook, steelhead, and bull trout. The South Fork Nooksack River is home to all nine salmonid species, including one of the populations of early Chinook salmon, the highest priority species for recovery for the Nooksack Indian Tribe. The abundance of salmon in the South Fork, especially spring Chinook salmon, has dramatically declined from historic levels, due primarily to high temperatures, low flows, sediment load, and loss of habitat. For example, the critical South Fork Chinook population suffered an unprecedented pre -spawn mortality event of 2,500 Chinook in early September 2021, which coincided with record returns of Chinook salmon to the South Fork Nooksack River. Two months later, the watershed suffered severe flooding in the lower watershed (Nooksack-Samish Fisheries Co -Managers Presentation). Innovative and immediate approaches are needed to address these climatic shifts in WRIA 1, protect the ESA -listed species in the Nooksack River Watershed, and offset future water withdrawals and other consumptive uses. The South Fork Nooksack Natural Storage Restoration project is an example of a collaborative solution that will increase streamflow in the South Fork (SF) Nooksack River during late spring, summer, and fall; decrease the frequency and duration of stream temperature exceedances; and offset the expansion of groundwater withdrawal and watershed caused by permit -exempt except wells. Importantly, the Project will include natural storage restoration efforts that will support the needed recovery of 02/29/2024 Page 1 of 4 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department WRSRP-2024-WhCoPW-00252 General Information ESA -listed salmon and other salmonid species. This project includes three distinct tasks, the first is to develop and implement natural water storage projects on property acquired by Whatcom County in the Black Slough site where low stream flows limit salmon health. To accomplish this task, the Nooksack Tribe and Whatcom County will design restoration treatments that will increase flood and alluvial water storage over approximately 166 acres at the Black Slough site. These restoration treatments will decrease the lateral groundwater drainage rate and increase the frequency and duration of overbank flow. The specific treatments being considered include the creation of wetlands through de -leveling, meandering/anabranching shallow channels, adding roughness in channel through the installation of beaver dam analogs, and/or increasing roughness and heterogeneity in the floodplain through additional plantings. This task also builds upon the extensive investments already made in the Black Slough area of the South Fork. The Nooksack Tribe, Whatcom Land Trust and Whatcom County have invested heavily in protection and acquisition, and data collection with support from other local, state and federal funding sources. Deliverables for this task include the preliminary design, final design, QAPP for monitoring, and the implementation and preliminary monitoring report. The next task of the project includes designing and implementing restoration treatments to increase alluvial water storage over 124 acres of the Acme Floodplain site recently acquired by Whatcom County. This task will build from and be integrated with the adjacent Fish Camp Integrated Restoration Project being undertaken by Nooksack Indian Tribe in partnership with BNSF and Whatcom County, which includes instream restoration and floodplain reconnection of the South Fork adjacent to the Acme floodplain site. The design of the alluvial storage will be based on what is most beneficial following final designs at the Fish Camp project to include restoration treatments that enhance existing features for natural storage (existing ponds), installing beaver dam analogs (BDAs), creating wetlands through de -leveling, meandering shallow channels, and/or increasing roughness and heterogeneity in the floodplain through additional plantings. Restoration and capture of floodwaters will increase natural water storage and groundwater discharge during base flow, thereby improving summer low flows and stream temperatures in the South Fork Nooksack River, and enhancing habitat for SF Nooksack Early Chinook and other ESA -listed salmonid species. Deliverables for this task include the preliminary design, final design, and implementation report. The final task includes a feasibility assessment that will identify additional natural storage sites in the South Fork.These natural storage projects will be designed and implemented to maximize streamflow benefits, and lessons learned from this project will be used in the future to advance the identification and development of natural water storage projects in the Lower Nooksack Mainstem and other parts of the Nooksack basin. The assessment will locate the highest priority options on Whatcom Land Trust and other privately held parcels and will use screen criteria - including climate resilience of sites during low flows and droughts - and restoration potential to determine the best opportunities for storage and outreach to those landowners. Several landowners have been contacted and have already shown 02/29/2024 Page 2 of 4 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department General Information W RSRP-2024-WhCoPW-00252 interest in restoration work in the Black Slough area. Outreach materials, preliminary designs of the Black Slough County -owned sites, and possible conceptual designs may be used to assist with landowner outreach. Deliverables for this tak include draft screening criteria, a restoration assessment and outreach strategy, and a natural storage feasibility assessment report. This project was chosen due to the broad support of members of the Watershed Management Board who will continue to track progress and receive updates from implementers. The County -owned properties have all been purchased and letters of support have been given from the WRIA 1 Watershed Management Board, Whatcom Land Trust, and Whatcom LIO Coordinator. Additionally, Whatcom County was awarded an Ecology streamflow restoration competitive grant in 2021 to purchase Stewart Mountain forest land. The County is successfully managing the land to increase water storage capacity, improve fish habitat, acquire water rights, and improve water management and infrastructure. The Nooksack Tribe has also managed numerous grants from Ecology and other state agencies. Potential Streamflow benefits of the project have been estimated across different tasks, yielding the 43.8 ac-ft to 139.8 ac-ft per year.

Yes If Yes, a Quality Assurance Project Plan (QAPP) will be required as a deliverable and environmental data may need to be entered into Ecology's Environmental Information Management (EIM) database. Overall Goal The overall goal of the project is to support recovery of ESA -listed and other salmonids and offset impacts of future permit exempt wells in the South Fork Nooksack River by advancing natural storage restoration projects that will increase streamflow in the South Fork during late spring, summary and fall and decrease the magnitude and duration of stream temperature exceedances. Projects will be designed and implemented on County -owned property in the Black Slough and Acme Floodplain sites, and feasibility will be assessed of similar restoration projects on Whatcom Land Trust and other private properties in the Black Slough, Landingstrip Creek, and Rothenbuhler Creek wetland complexes. A secondary goal is to apply the lessons learned from this project to advance the identification and development of natural water storage projects in the Lower Nooksack Mainstem and other parts of the Nooksack basin. 02/29/2024 Page 3 of 4 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department WRSRP-2024-WhCoPW-00252 Project Characterization Project Themes Select a primary and secondary theme that best describes the work to be achieved during this project.

The specific treatments being considered include the creation of wetlands through de -leveling, meandering/anabranching shallow channels, adding roughness in channel through the installation of beaver dam analogs, and/or increasing roughness and heterogeneity in the floodplain through additional plantings. The task will include project management, hiring and oversight of contractors to develop preliminary and final designs, landowner outreach, permitting, construction oversight, and monitoring. This is project 19NG in the Draft Rule Supporting Document (ECY 19-11-093, p 41). Task Goal Statement The goal of this task is to restore floodplain wetland extent and hydrologic function on County -owned properties in the Black Slough wetland and riparian complex. Restoration will increase natural water storage and groundwater discharge during base flow, thereby improving summer low flows and stream temperatures in the South Fork Nooksack River, and enhancing habitat for SF Nooksack Early Chinook and other ESA -listed salmonid species. An additional goal of this task is to build upon the extensive investments already made in the Black Slough area of the South Fork. The Nooksack Tribe, Whatcom Land Trust and Whatcom County have invested heavily in protection and acquisition, and data collection with support from other local, state and federal funding sources. Additionally, while the SF Nooksack Temperature TMDL was being developed, the Nooksack Tribe (funded by Ecology, EPA, and BIA) worked with the SF community to develop a watershed conservation plan and advance reach -scale acquisition, riparian and wetland restoration planning. Plantings on 31 acres of County -owned land represent the initial effort to return this cleared and ditched area to naturally functioning condition. Task Expected Outcomes Design, construction and monitoring of a natural storage project on Whatcom-county owned properties in Black Slough.

Design will build from and be integrated with that of the adjacent Fish Camp Integrated Restoration Project, which includes instream restoration and floodplain reconnection of the South Fork adjacent to the Acme floodplain site. The design of the alluvial storage will be based on what is most beneficial following final designs at the Fish Camp site and likely to include restoration treatments that enhance existing features for natural storage (existing ponds), installing BDAs, creation of wetlands through de -leveling, meandering/anabranching shallow channels, and/or increasing roughness and heterogeneity in the floodplain through additional plantings. The task will include project management, hiring and oversight of contractors to develop preliminary and final designs, landowner outreach, permitting, construction oversight, and baseline and implementation monitoring. Monitoring will occur in subsequent phases. This is part of Project 28 in the Draft Rule Supporting Document (ECY 19-11-093, p 41). Task Goal Statement The goal of this task is to restore wetland extent and function on County -owned properties in the Acme Floodplain wetland complex. Restoration will increase natural water storage and groundwater discharge during base flow, thereby improving summer low flows and stream temperatures in the South Fork Nooksack River, and enhancing habitat for SF Nooksack Early Chinook and other ESA -listed salmonid species. An additional goal is of this task to build on previous restoration projects in the area, specifically integrating instream restoration and floodplain reconnection efforts with the South Fork Nooksack River Fish Camp Integrated Flood and Fish Project. This project, which is a collaboration between the Nooksack Indian Tribe Natural Resources Department and the Whatcom County Public Works River and Flood Division, is developing broadly -supported, multi -beneficial solutions to reduce flood risk to the Acme community and restore habitat for ESA -listed early -timed Chinook salmon and other salmonid species. Task Expected Outcomes Design and construction of a natural storage project on Whatcom-county owned properties in the Acme Floodplain, upstream of the Black Slough project and adjacent to another large restoration effort underway by Nooksack Tribe. 02/29/2024 Page 7 of 10 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department WRSRP-2024-WhCoPW-00252 Scope of Work - Additional Tasks: 3 - Acme Floodplain Natural Storage Implementation Recipient Task Coordinator Treva Coe Deliverables Deliverable # Description Due Date Received?

Nooksack Tribe has been funded to synthesize previous wetland and natural storage assessment and restoration planning efforts, including South Fork Nooksack River Acme -Confluence Reach Restoration Planning, Reach -Scale Plan: South Fork Nooksack River (Nooksack Natural Resources 2017), South Fork Nooksack River Alluvial Water Storage Modeling (Natural Systems Design 2022a), and Beaver Restoration on the South Fork Nooksack (Ingram Environmental 2016), and that synthesis (expected by December 2024) will inform the prioritization of properties for natural storage restoration. We shall reach out to landowners of properties with high natural storage restoration priority to determine their willingness to allow for natural storage restoration. This landowner outreach will build upon previous outreach efforts (Nooksack Natural Resources 2017) that identified several landowners willing to allow restoration. Outreach materials may include design concepts developed in Tasks 2 and 3. Assessment of feasibility on select Whatcom Land Trust and other privately owned properties will involve assessment of cost, technical hurdles or barriers, permitting hurdles or barriers, operations and maintenance needs, interested parties and responsibilities, local support, uncertainties, project life span, and connections to existing projects and actions. This task contributes to Project 28 in the Draft Rule Supporting Document (ECY 19-11-093, p 41). Task Goal Statement The primary goal of Task 4 is to advance the readiness of high priority natural storage restoration projects in the lower South Fork Nooksack River valley that can be submitted for design and implementation funding in future grant rounds. A secondary goal is to apply lessons learned through landowner outreach and feasibility assessment in these areas to advance planning and build support for natural storage restoration in the Lower Nooksack and throughout the watershed. Task Expected Outcomes Feasibility assessment that sets up the WRIA 1 Watershed Management Board to identify additional natural storage sites and implement projects as part of a next phase of work building from Tasks 1 and 2. 02/29/2024 Page 9 of 10 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department WRSRP-2024-WhCoPW-00252 Scope of Work - Additional Tasks: 4 - Feasibility of natural storage in the South Fork Recipient Task Coordinator Chris Elder Deliverables Deliverable # Description Due Date Received?

The site known as Black Slough Natural Storage (Task 2) is 3.26 miles from where the Black Slough enters the South Fork Nooksack at RM 2.0; accordingly implementation of task 2 will benefit 3.26 miles of Black Slough downstream and 2.0 miles of the South Fork Nooksack River. Upstream, the site known as Acme Floodplain (Task 3) is also focused on County -owned property and adjacent to other significant restoration investments in this reach (Fish Camp Reach Integrated Restoration Project). This project will benefit 7 miles of the South Fork Nooksack River downstream of the property. Although task 4 will not directly benefit stream and river habitat, it will advance readiness of natural storage restoration that will benefit 2, 7 or 10.4 miles of South Fork Nooksack River for projects in the Black Slough, Landingstrip Creek, or Rothenbuhler Creek wetland complexes, respectively. Clearly and completely describe the project streamflow benefits. Include the amount of increased streamflow (if known), timing, and location of streamflow benefits. Potential streamflow benefits of the project have been estimated using different sources. Streamflow benefits in terms of acre-feet have been estimated based on alluvial water storage modeling described in Natural Systems Design's (2022) South Fork Nooksack River Alluvial Water Storage Modeling. NSD developed a screening -level geospatial and computational workflow that used high resolution topographic data, relevant spatial datasets (e.g. precipitation, drainage area), and geomorphic analysis to estimate the amount of restorable surface and subsurface water storage at a reach -scale. The geospatial dataset includes a drainage network, with each segment attributed with relative alluvial water storage potential (acre-feet per mile). These segments were intersected with various polygons of interest (e.g. County ownership for tasks 2 and 3, feasibility study area boundary for task 4), new segment lengths were calculated, and segment -specific water storage potential (acre-feet) calculated as the product of segment length (mi) and relative water storage potential (acre-feet per mile). Cumulative alluvial water storage potential was summed across different areas of interest, yielding the following estimates: (1) Task 2: alluvial water storage potential across County Black slough properties: 30.3 ac-ft; (2) Task 3: alluvial water storage potential across County Acme floodplain property: 13.5 ac-ft; (3) Task 4: alluvial water storage potential across: (a) feasibility area: 451 ac-ft (302 ac-ft in Black Slough portion, 149 ac-ft in Rothenbuhler/Landingstrip portion); (b) Whatcom Land Trust -owned properties within W RSRP-2024-WhCoPW-00252 02/29/2024 Page 3 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration feasibility area: 95.2 ac-ft (19.1 ac-ft in Black Slough portion, 76.1 ac-ft in Rothenbuhler/Landingstrip portion). The estimate provided in the table ranges from 43.8 ac-ft [sum of (1) and (2)] to 139.8 ac-ft [sum of (1), (2), (3b)]. Streamflow benefit in terms of cfs is estimated conservatively for Task 2 only using Natural Systems Design's (2022) Black Slough Hydrologic Analysis, which found that restoration of 1.0 mile of Black Slough could contribute a mean of 0.8 cfs to the SFNR during June -September in a dry year and 0.5 cfs during June -September in a wet year. Linear scaling of that estimate to the length of Black Slough within County -owned properties (0.7 miles) yields the range provided in the table below. Other related assessments indicate the restoration potential of the project area. Although the construction of beaver dam analogs (BDAs) is anticipated in both Tasks 2 and 3, colonization of BDAs by beavers will increase certainty they will persist over time. Beaver habitat potential modeling (Ingram Environmental 2016) indicates there are 6894 10-m grid cells in the Black Slough feasibility area and 2785 10-m grid cells in Land ingstrip/Rothenbuhler Creek feasibility area with high beaver habitat potential, corresponding to about 42.8 and 17.3 miles of stream, respectively. Within properties owned by the Whatcom Land Trust, there are 277 10-m grid cells in the Black Slough feasibility area and 1266 10-m grid cells in the Land ingstrip/Rothenbuhler Creek feasibility area with high beaver habitat potential, corresponding to about 1.7 and 7.9 miles of stream, respectively. inally, Anchor QEA's Water Storage Alternatives Report (November 2023 review draft) indicates that "in concept, introduction of beaver pond complexes over 20 stream miles could create 600 acre-feet of storage and 2 to 16 cfs of instream flow benefit." Scaling that to the 9.6 miles of high beaver habitat potential on WLT properties in the feasibility area yields 288 acre-feet of storage and 1 to 7.7 cfs. Finally, Ecology's (2000) Potential Wetland Restoration Sites in the Nooksack River Basin identified 1517 and 419 acres of wetland with high low flow restoration potential and 419 acres in the Black Slough and Landingstrip Creek/Rothenbuhler Slough portions of the feasibility area, respectively.

The Nooksack Basin is one of five biogeographical regions in the Puget Sound Chinook Evolutionarily Significant Unit (ESU) and supports two of the 22 remaining Puget Sound Chinook populations (64 FR 14308, Mar. 24, 1999). Both populations are native, early run, and considered essential for the recovery of the threatened Puget Sound Chinook ESU (WRIA 1 2005). Both native Nooksack Chinook populations also have critically low wild spawner abundances, and both are supported by hatchery population -rebuilding programs to prevent extinction while habitat productivity is restored. Estimated historic abundances of SF early Chinook was 13,000 (Mobrand Biometrics, unpublished data). Average spawner escapement for the most recent 5 years for which estimates are available (2017-2021) was 213 natural -origin spawners. The risk of inaction is great: in 2021, 2291 hatchery -origin and 41 natural -origin SF Chinook died on the spawning grounds before they could spawn. The South Fork Nooksack River (SFNR) is home to all nine salmonid species, including one of the populations of early Chinook salmon, the highest priority species for recovery in WRIA 1 . The abundance of salmon in the South Fork, especially early Chinook salmon, has dramatically declined from historic levels, due primarily to habitat degradation from the legacy impacts of various land uses such as commercial forestry, agriculture, flood control, and transportation infrastructure. Per the Summary of Nooksack Chinook Limiting Factors (2022 draft), the primary limiting factors for Chinook recovery in the South Fork are lack of habitat diversity and high temperatures, low flows and sediment load. The South Fork Nooksack River supports most all freshwater life stages of Chinook salmon (Oncorhynchus tshawytscha — listed as threatened under ESA), including adult upstream migration, holding and spawning, egg development, and juvenile rearing and outmigration, adult upstream migration. High temperatures can stress holding and spawning fish, which increases prespawn mortality and vulnerability to disease or alter the timing of emergence or upstream spawning. Low streamflows W RSRP-2024-WhCoPW-00252 02/29/2024 Page 5 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration reduce habitat availability, impede upstream migration, dewater redds or juvenile rearing habitat, and contribute to high stream temperatures. Bull trout in WRIA 1 constitute a component of the Coastal -Puget Sound Distinct Population Segment (DPS), listed as Threatened (64 FR 58910, Nov. 1, 1999), Puget Sound/Strait of Georgia coho salmon, including Nooksack coho, is a species of concern, and NOAA Fisheries listed Puget Sound steelhead in 2007 as a threatened species. Because the Nooksack basin represents such an important component of the Puget Sound diversity for ESA -listed salmonids, it has become a major focus for salmon recovery for the region and the state. The proposed actions are part of a longer -term strategy and series of actions to address limiting factors in the South Fork Nooksack River. Implementing natural storage restoration in the South Fork Nooksack watershed will benefit Chinook by directly addressing the priority limiting factor of low streamflow, which will in turn indirectly address the priority limiting factor of high stream temperatures., The project is expected to reduce prespawn mortality and increase the number of successful spawners in the South Fork for those species that migrate in summer: Chinook, bull trout, and summer steelhead. The project is also expected to increase juvenile rearing productivity. Describe the existing causes of aquatic resource degradation that this project is designed to address. How will the project have meaningful effect on these problems without causing adverse impacts on the watershed ? Restoring natural hydrology and water storage in the South Fork will not have any adverse impacts on the watershed. The proposed activities will restore function in the lower South Fork Nooksack without causing any adverse impacts. All implementation work is being conducted on county -owned property and the suite of actions have broad support by partners in the basin and will be designed with consideration for adjacent infrastructure. Habitat in the South Fork Nooksack has been altered by past land use including commercial logging of the hillsides and of the riparian forest on the floodplain including clearing for agriculture or residential uses. The removal of large trees of the size to provide habitat functions has reduced habitat complexity and diversity in the tributaries and the wood present tends to be relatively small and mobile. This has decreased the number of stable log jams that are present to maintain forested islands and the associated stable side channels. Stable side channels provide greater egg survival for spawning chinook, steelhead, chum, pinks, coho, and sockeye) in comparison to relatively unstable channel braids that shift frequently and where salmon redds are likely to be scoured or buried. Historic loss of riparian cover from logging or clearing for development, instream wood removal, and increased W RSRP-2024-WhCoPW-00252 02/29/2024 Page 6 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration sediment loads have created relatively wide and shallow channels in places which are subject to increased exposure to the sun and heating of the water producing stress or mortality to both adults or juvenile salmonids. Restoration of wetlands and buffers in low gradient floodplain tributaries has been identified as an essential action to address the South Fork Nooksack River temperature Total Maximum Daily Load (TMDL) which directly impacts productivity of ESA salmonid species (EPA 2020). Wetland/tributary restoration within Black Slough was also identified as an action in the Ecology-NEP funded Reach Scale Plan (NCNR 2017). Many tributaries are also subject to low flow or even complete dewatering in the lower reaches where they enter into and cross the floodplains of both forks. Often this occurs in the lower reaches where the creek crosses its alluvial fan and where multiple natural and anthropogenic factors, such as dredging to maintain flood conveyance at bridges, likely exacerbate the frequency and duration of low to no flow. (Nooksack River Watershed Vision and Implementation Strategies) Historically, Black Slough area was a vast palustrine wetland complex with emergent, scrub -shrub, and forested vegetation (Collins and Sheik 2004). A network of agricultural ditches exist that drain wetland areas for agricultural uses. The predominant agricultural use in the Black Slough tributary is harvest of pasture grass, and silage corn production for dairies. Much of the land has been fallowed due to how wet the area is and is now mainly infested by reed canary grass. The combined effects of clearing forest vegetation and ditching Black Slough for conversion to agriculture has resulted in a loss of natural water storage areas within wetlands connected to the slough, reduction of streamflow, and increased temperatures. Evidence also suggests that beaver dams can facilitate a decrease in water temperatures downstream. One study assessed the effectiveness of Beaver Dam Analogues (BDAs) to augment beaver activity and restore steelhead habitat from a degraded condition. A battery of ecological parameters including stream temperature, were measured for three years prior to the experimental treatment and for four years after said treatment. Following the experimental treatment, the maximum stream temperatures of reaches that had gained beaver dams were an average of 1.47°C cooler than the reference reaches which had no beaver dams. The authors attributed this thermal refugia to upwelling of cold water from beaver ponds; some were 10°C cooler than the correspondent daily high values from that reach. (Bouwes et. al., 2016). A similar study on the same creek in 2012 found support for this hypothesis: the treatment reach that had BDA's installed exhibited an overall lower distribution of stream temperatures at the diel peak than the control reach during the experimental period, (Consolati et al.). The environments fostered by beavers' dam building activities can also encourage considerable riparian vegetation growth, which can in turn provide shade, cooling the stream, (Castro, Pollock, Jordan, Lewallen, & Woodruff, 2015; Devries, Fetherston, Vitale, & Madsen, 2012). Describe evidence that the proposed project will provide stated benefits following project completion. W RSRP-2024-WhCoPW-00252 02/29/2024 Page 7 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration As described in NSD's South Fork Nooksack River Alluvial Water Storage Modeling report, "stream restoration... has the potential to increase storage of sediment, surface water, and subsurface water (Abbe et al., 2019). This stored water is then potentially available for riparian water use and for contributing colder groundwater to low flows during the dry season. The conceptual basis for this approach to restoring water storage is that where local water elevation is raised, groundwater elevation is raised, and subsurface water storage is increased. Since the rate at which groundwater flows is more than four orders of magnitude slower than surface water, the groundwater aquifer acts like a sponge, receiving water during high spring flows and returning some of that water during low summer flows (Hunt et al., 2018; Tague et al., 2008). Local water elevation can be raised via in -stream restoration actions that re-aggrade deep channels that have cut down into the underlying sediments or bedrock, or via the introduction of grade control that sets the downstream water level. The latter has a variety of natural analogs, such as landslides, resistant underlying rock layers, and log jams (Abbe & Montgomery, 2003; Hancox et al., 2005; Montgomery & Abbe, 2006)." In their Nooksack River Basin Water Supply and Stream Flow Augmentation report (2023 Final Draft), Anchor QEA described the potential benefits of beaver relocation or beaver dam analogs (BDAs): Beaver reintroduction or addition of structures that mimic beaver dams (BDAs or post -assisted log structures [ PALS]) are commonly implemented where restoration efforts seek to reintroduce sinuosity to channels and re-engage adjacent riparian and floodplain areas. The benefits of beaver dams include greater surface water storage on the order of 200% greater inundation area compared to reaches without beaver activity (Bouwes et al. 2016) and 21% more seasonal flood water stored through the summer (Westbrook et al. 2006). In the Snohomish River Basin, a group of five successful beaver relocation sites stored 22 times as much surface water as control sites without beaver (Dittbrenner et al. 2022). In ponds that are approximately 1 acre-foot in size, subsurface storage typically exceeds volumes observed on the surface by 2 to 3 times (Dittbrenner et al. 2022). Water volumes are not only increased in the area of beaver activity, but also are typically augmented in downstream reaches with an associated delay in attenuation of summer flows occurring due to augmented recharge of aquifers (Pollock et al. 2003; Westbrook et al. 2006). How does this project and related benefits align with community needs and other watershed planning processes? Include specific references to other plans that specify this project, or that this project supports. The WRIA 1 watershed has water availability, water quality, and salmon recovery challenges. Streamflows regularly fall below regulatory flows and flows needed to support salmon recovery. Receding glaciers, summer drought conditions, and changing climate conditions are currently contributing to seasonal low and high flows. W RSRP-2024-WhCoPW-00252 02/29/2024 Page 8 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration Modeling and analysis from the WRIA 1 Regional Water Supply Plan Phase 2 project and modeling completed by Western Washington University show that a changing climate will continue to cause significant impacts to streamflows in the next 50 years with timing of runoff shifting toward higher winter flows leading to additional flooding and worsen low summer streamflows for both instream and out -of -stream uses. Recent events in WRIA 1 illustrate the devastating impacts these conditions are having on local and cultural resources and the community. The critical South Fork Chinook population suffered an unprecedented pre -spawn mortality event of 2500 Chinook in early September 2021 which coincided with record returns of Chinook salmon to the South Fork Nooksack River. Factors contributing to this devastating event included degraded habitat, low stream flows, and high water temperatures. Two months later, the watershed suffered severe flooding in the lower watershed. Currently snowpack is 50% of the 30-year median (WA SNOTEL Current Snow Water Equivalent, accessed February 11, 2024). The Washington Department of Ecology is proceeding with a water rights adjudication in WRIA 1 with an anticipated filing in spring of 2024 While the adjudication will review whether each water right is legal, how much water can be used, and its priority in times of water shortages, it does not identify solutions for water management. The temporal and geographic shifts in the hydrograph will require a collaborative approach to implementing solutions like those the WRIA 1 Watershed Management Board is discussing and investigating. The WRIA 1 Watershed Management Board is an integrated and collaborative planning structure established by Interlocal Agreement. The functions of the WRIA 1 Watershed Management Board include coordinating and facilitating implementation of the WRIA 1 Watershed Management Project, WRIA 1 Lead Entity Salmon Recovery program, and the Whatcom Local Integrating Organization. Several studies have been advanced under this framework including evaluation of water storage solutions that will have a positive impact on streamflows. The work proposed under this grant to Ecology's Streamflow Restoration Grant Program comes out of the natural water storage approaches that have been identified through the various WRIA 1 water management studies and represents a broadly supported suite of actions to continue addressing habitat and hydrology restoration in the South Fork Nooksack immediately. In particular, the strategy for South Fork wetland restoration and floodplain reconnection are called for in several watershed plans. A number of assessments, acquisitions, restoration planning and riparian planting projects have been funded and point to this proposed effort as the next necessary step in restoration of the South Fork Nooksack. The following watershed planning processes and plans call for restoring the South Fork Nooksack River broadly as a salmon recovery and water availability strategy, and specifically through floodplain reconnection, wetland restoration, and natural storage options such as beaver analogs: WRIA 1 Salmonid Recovery Plan, April 30, 2005 (https:Hsalmonwrial.org/sites/default/files/2019-09/WRIAl SalmonidRecoveryPlan.pdf) W RSRP-2024-WhCoPW-00252 02/29/2024 Page 9 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration Reach -scale Plan: South Fork Nooksack River, Nooksack Indian Tribe, June 2017 (https://www.sfnooksack.com/files/FINAL%20SFN R°/o20reach%20scale%20Plan%206-21-17.pdf) South Fork Nooksack River Watershed Conservation Plan, Nooksack Indian Tribe Natural Resources Department, May 2017, Updated January 2018 (https://www.sfnooksack.com/files/SFN R%20 Watershed%2OConservation%20PIan%2OUpdated%2OJan%20 2018%20FINAL!.pdf) Technical Memorandum Final Task 2 Deliverable- Projects and Actions, prepared by WRIA 1 ESSB 6091 Technical Consultant, RH2, for Washington State Department of Ecology, October 2, 2018 South Fork Nooksack Temperature Total Maximum Daily Load Water Quality Improvement Report and Implementation Plan, Washington State Department of Ecology, approved by EPA 2020 (https://apps.ecology.wa.gov/publications/documents/2010007.pdf) WRIA 1 Regional Water Supply Plan Phase 2 Report, RH2, January 2023 https://drive.google.com/file/d/1 xw7BEmUZmhkAUMSy7tYsui-6jWeKn4f-/view?usp=sharing StoryMap Summary of WRIA 1 Regional Water Supply Plan Phase 2 Report, January 2023 (https://wria1 project.whatcomcounty.org/resources/water-supply-storymap) South Fork Nooksack River Fish Camp (Ts'eq) Integrated Flood and Fish Project (https://www.whatcomcounty.us/3106/South-Fork-Fish-Camp-Integrated-Project) PROJECT BUDGET What information did you use to estimate total project costs and develop your budget?

Provide documentation or other information used to estimate project costs. https://ecyeagl/lntelliGrants_BASE/ Uplo ad/272104_920672_1-South ForkNatural StorageBudget.xlsx What level of operations and maintenance will the project need to continue its benefits? Operations and maintenance costs are not eligible costs for this funding opportunity. If the project needs operation and maintenance, how do you plan on supporting these needs throughout the life of the project (if applicable)? Operation and maintenance costs will depend on the specific natural storage restoration elements included in the designs for Tasks 2 and 3. Restoration elements that restore natural hydrologic processes (de -leveling, meandering/anabranching shallow channels) are expected to require minimal maintenance, and design will evaluate potential for sedimentation that may affect persistence. Beaver dam analogs will be designed to remain stable during high flow events, although BDAs have a lifespan of a couple of decades under the best case scenario (Ingram 2016). The wood is subject to decomposition and washout from flooding. As such, BDAs may require maintenance in the future unless and until beavers colonize the structures. As indicated above, the project area is an area of generally high beaver habitat restoration potential. Projects will be designed to avoid unwanted flooding of adjacent properties, although some maintenance may be required in the event of unanticipated flooding beyond the project footprint. The need for maintenance will be evaluated by Whatcom County Public Works staff during periodic site monitoring. If maintenance is needed, WCPW staff will work in coordination with staff from NIT to identify needed actions, using in kind funding if possible or securing grant funding if necessary. If this grant does not cover the full cost of the project, identify other sources of funding for the completion of the project, as well as operation, maintenance, monitoring, and contingency implementation costs over the lifetime of the project. W RSRP-2024-WhCoPW-00252 02/29/2024 Page 11 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration Given the short time period of the grant (3 years), we plan to defer riparian planting and ongoing effectiveness monitoring for Tasks 2 and 3 to other funding sources. Sources of funding for riparian and wetland planting include Washington Conservation Commission and Washington Recreation and Conservation Office; both agencies have new riparian grant programs funded by the Climate Commitment Act. We also expect to apply for Ecology Streamflow Restoration funding in future grant rounds, including to design and implement projects developed through the Task 4 feasibility assessment. There is considerable federal and state funding available to federally recognized tribes for climate resilience and adaptation, and natural water storage restoration is a priority climate resilience and adaptation strategy for the Nooksack Indian Tribe. PROJECT DURABILITY AND RESILIENCY Describe how this project and the anticipated benefits are tailored to the local conditions where the project will be implemented. The project setting is within a low gradient floodplain that has been ditched and cleared for agricultural use. Historically, the channel had much greater sinuosity, the surrounding area had extensive wetland complexes and the area was forested. The proposed work will return the sites to a more natural condition and improve hydrologic connection and function while also using tools like BDAs to simulate beaver activity and constructing contours and deleveiling the surface to engineer the mosaic of features that would have been present without past land use practices. We anticipate this work building from this initial restoration through natural recruitment of trees and shrubs and through beaver reoccupying the sites. We will monitor their activity to determine if water level control devices, such as beaver deceivers or pond levelers, are warranted. We will expand upon the lessons learned from this phase as additional restoration work takes place on the sites identified in the feasibility assessment (Task 4) on adjacent properties. Explain how the project is feasible and likely to be successful in providing the proposed benefits. Task 2 (Black Slough) and Task 3 (Acme Floodplain) will include design and implementation of restoration actions on County -owned sites. Whatcom County previously acquired these parcels in Black Slough and in the Acme Floodplain. There are not impediments to project implementation or feasibility at these sites. The W RSRP-2024-WhCoPW-00252 02/29/2024 Page 12 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration acreage currently being leased for agricultural production is short-term and will end prior to restoration activities. The adjacent landowners are aware of the projects. Task 4 explicitly includes feasibility assessment for future natural storage restoration projects. The landowner outreach aspect of Task 4 builds on work underway by the County, Nooksack Tribe and Whatcom Land Trust with known interest by key community leaders. The area has 50-100 households and the emphasis will be in the areas with the highest potential benefits. The Land Trust has completed a landowner acknowledgement form related to Task 4 to demonstrate their support of the feasibility assessment and successful future implementation on their properties if restoration opportunities are identified. Several technical studies cited above point to the high potential for success in achieving the benefits due to the current hydrology, tried and true tested techniques, and preliminary effectiveness monitoring to be conducted by the Tribe. The Nooksack Tribe will deploy a series of combination groundwater and surface water surface water level -loggers, stream temperature sensors, and photo points to compare baseline conditions to restored conditions. Effectiveness monitoring beyond the project period will be secured from other sources or future streamflow restoration grant rounds. Explain how the project benefits are sustainable, and occur at regular intervals, and will persist over time. Table 4-33 in the NSD — WWU — NIT Black Slough Report described the anticipated impacts and benefits of SF Nooksack Natural Storage Program. The earthworks element of the project is expected to persist for decades, perhaps in perpetuity (per requirements of Ecology's draft NEB guidance) but without a better idea of sedimentation rates in the system, there is some uncertainty of how those actions will persist over time. Beaver dam analogs have a lifespan of a couple of decades under the best case scenario (Ingram 2016). The wood is subject to decomposition and wash out from flooding much like a natural beaver dam. Takeaways from this project will apply to projects in the Lower Nooksack and other parts of the South Fork. It is expected that operation and maintenance costs will depend on the specific natural storage restoration elements included in the final designs for Tasks 2 and 3, though the target scenario is to implement projects that require minimal maintenance and allow for ongoing and compounded benefits over time. Restoration elements that restore natural hydrologic processes (de -leveling, meandering/anabranching shallow channels) are expected to require minimal maintenance, and design will evaluate potential for sedimentation that may affect persistence. Beaver dam analogs will be designed to remain stable during high flow events, although BDAs have a lifespan of a couple of decades under the best case scenario (Ingram 2016). The wood is subject to decomposition and washout from flooding. As such, BDAs may require maintenance in the future W RSRP-2024-WhCoPW-00252 02/29/2024 Page 13 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration unless and until beavers colonize the structures.

If maintenance is needed, WCPW staff will work in coordination with staff from NIT to identify needed actions, using in kind funding if possible or securing grant funding if necessary.] Describe known uncertainties and risks in regards to the proposed project. How do you plan on minimizing these uncertainties and risks? Beavers are active in this part of the Black Slough watershed. How beavers will respond to changes from the restoration actions is unknown. Project design will include consideration of how the area may retain water on the site and surrounding properties using desktop tools such as GIS with recent LiDAR data. The Tribe has a sub -centimeter resolution GPS that can be used for implementation and effectiveness monitoring for topographic and bathymetric surfaces. Other adaptive management measures that may be used are beaver deceivers and pond levelers through beaver dams. It is uncertain how delaying the timing of water moving through the system (e.g., surface water retention) will result in increased discharge within the South Fork Nooksack River during the targeted time of the summer low flow period. To best plan future SFR proposals within the Black Slough sub -basin we propose working with a hydro -geologist to better understand the relationship of retiming water within the low flow period. At this time we anticipate that implementation of the proposed project could result in 10 acre-ft increase in discharge in Black Slough and SFNR. Any other uncertainties and risks associated with the proposed storage projects will be evaluated during the design process and final designs will consider and mitigate identified potential risks. How did you consider the anticipated impacts of climate change and drought in your project development? In the coming decades, the Nooksack River Watershed is expected to undergo significant changes due to climate shifts. Notably, the mountains draining into Puget Sound are projected to experience a 29% reduction in snowpack by the 2040s. This alteration will impact the region's hydrology, leading to a transition from a mixed snow and rain dominant system to a rain -dominant one. By the 2080s, peak stream flow in the Nooksack River is anticipated to occur approximately 27 days earlier in the year, compared to the average W RSRP-2024-WhCoPW-00252 02/29/2024 Page 14 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration between 1970 and 1999. Furthermore, under the high -emissions scenario ( RCP 8.5) that is consistent with current trends, median August streamflows in the South Fork are projected to decrease by 56% by 2050 and 65% by 2075 relative to the same historical average (Murphy 2016), while peak streamflows in the South Fork are projected to increase 23% and 34% by the 2050s and 2080s, respectively (Paul 2023). Rising summertime stream temperatures pose an additional challenge, exceeding the thermal tolerance of most fish species. Temperature modeling conducted in association with the South Fork Nooksack River Temperature TMDL (Butcher et al. 2016) indicates that average and maximum temperatures in the South Fork (averaged across all reaches) during critical periods (7Q10 flows) will increase by over 5°C and almost 60C by the 2080s The proposed project is consistent with adaptation plans that have been developed to date. The Qualitative Assessment: Evaluating the Impacts of Climate Change on Endangered Species Act Recovery Actions for the South Fork Nooksack River, WA report (EPA 2016) indicates that restoring floodplain wetlands is a high priority in the lower South Fork and will ameliorate both temperature increases and base flow decreases due to climate change. The Nooksack Tribe's Climate Adaptation Plan for Key Species and Habitats (Morgan and Krosby 2020) identifies the need to "prioritize wetland habitats for active management, restoration, and protection across jurisdictional boundaries" and "identify, protect, and where possible, create critical wetland habitat". Finally, Whatcom County's Climate Action Plan (2021) specifies "develop demonstration projects to increase streamflow and lower stream temperatures" and "restore and protect wetlands, riparian zones, and upland forested headwater areas." as key priorities for "Strategy 2: Restore and protect Streamflow to a Level and Temperature that Ensures Year -Round Salmon Migration and Survival." This project would play a crucial role in implementing one of the most important actions to address climate change in the Nooksack River watershed. READINESS TO PROCEED AND PROJECT MONITORING Which affected tribes, governments, and key stakeholders have you engaged and how have you engaged with them during project development? This application is submitted by Whatcom County with the Nooksack Tribe as an implementing partner under the framework of the WRIA 1 Watershed Management Board, which includes Lummi Nation, Nooksack Tribe, Washington Department of Fish and Wildlife, Whatcom County, and the Cities of Blaine, Bellingham, Everson, Ferndale, Lynden, Nooksack and Sumas. The WRIA 1 Board facilitates implementation of the WRIA 1 W RSRP-2024-WhCoPW-00252 02/29/2024 Page 15 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration Watershed Management Plan, the WRIA 1 Salmonid Recovery Plan and serves as the WRIA 1 Lead Entity and Whatcom Local Integrating Organization. Members of the WRIA 1 Watershed Management Board have vetted this application and are supportive of the project. Whatcom Land Trust is a key stakeholder in the project. Property owned and managed by the Whatcom Land Trust will be evaluated as part of the feasibility study (Task 4). Staff with Whatcom Land Trust, Whatcom Conservation District, Whatcom County, Nooksack Tribe Natural Resources, and Ag Water Board of Whatcom County participated in planning meetings to identify concepts. Lummi Nation Natural Resources staff were unable to attend the planning meetings but were kept engaged by the Whatcom LIO Coordinator. Concepts developed from the planning team were refined into proposal tasks by staff of Whatcom County and Nooksack Tribe Natural Resources. The WRIA 1 Management Team, which is the administrative team of the WRIA 1 Watershed Management Board, was updated monthly. The WRIA 1 Planning Unit was provided a brief update at their November 14th meeting on the developing concepts, at their January 24th meeting on the application focus of natural storage solutions, and at their February 28th meeting on the final application. Due to the timing of preparing the grant application and the two meeting rule the Planning Unit has for approvals, there was insufficient time to request a letter of support. Letters of support include: WRIA 1 Watershed Management Board, Whatcom Land Trust, and Whatcom LIO Coordinator. Provide letters of support and other evidence. https://ecyeag 1/1 ntel I i Grants — BASE/_U pload/272104_920684- Whatcom LandTrust_LOS. pdf https://ecyeagl/1ntelIi Grants _ BASE/ _Upload/272104_920684_2-SRGSupportLetter_WRIA1 WMB.pdf https://ecyeagl/I ntelliGrants_BASE/_Upload/272104_920684_3-SRGSupportLetter_LIO-LECoordinator_022 8-2024.f.pdf What is the current status of this project? The project is ready to begin upon the signing of the grant award. This project was chosen due to the broad support of members of the Watershed Management Board who will continue to track progress and receive updates from implementers. The individual tasks are each in a different phase, but together this represents a series of important streamflow benefits in the South Fork. The County -owned properties have all been purchased and any agricultural leases will expire by the time construction begins at either Black Slough or Acme Floodplain sites. These tasks are offset by a year so that work can begin immediately on the natural W RSRP-2024-WhCoPW-00252 02/29/2024 Page 16 of 20 WATER RESOURCES STREAMFLOW RESTORATION PROGRAM Organization: Whatcom County - Public Works Department Streamflow Restoration storage at Black Slough. Design work for Acme Floodplain will maximize benefits by waiting for final designs of an adjacent restoration project (Fish Camp Integrated Flood and Fish Project). The feasibility assessment to work on Whatcom Land Trust and other private properties will begin immediately. Past conversations with landowners and partnering entities have signaled keen interest in restoration actions on their properties.
