Renton ® AND ECONOMIC DEVELOPMENT PLANNING DIVISION CERTIFICATE OF EXEMPTION FROM SHORELINE SUBSTANTIAL DEVELOPMENT DATE: PROJECT NUMBER: PROJECT NAME: PROJECT MANAGER: PROPERTY OWNER: APPLICANT: CONTACT: PROJECT LOCATION: February 4, 2016 LUA15-000866, SME Bird Island Shoreline Enhancement Project Jill Ding, Senior Planner Washington State Department of Natural Resources, 950 Farman Avenue North, Enumclaw, WA 98022 Washington State Department of Natural Resources, 950 Farman Avenue North, Enumclaw, WA 98022 Monica Shoemaker, Washington State Department of Natural Resources, 950 Farman Avenue North, Enumclaw, WA 98022 1201 Lake Washington Blvd N PROJECT DESCRIPTION: The Washington State Department of Natural Resources (DNR) in partnership with the City of Renton Parks Department is proposing to enhance approximately 525 feet of shoreline habitat and approximately 0.4 acres of upland habitat with the goal to improve the migratory and rearing habitat for juvenile Chinook salmon and public access for park users. The scope of work includes removal of debris that is littered around the shoreline, removal of invasive plants, native planting, placement of sediment for shallow water habitat, placement of large wood, and trail improvements. While this application is tied in the permit system to the Coulon Park parcel, the project site itself is actually located just outside of the City limits on DNR land and does not have a parcel number of its own. Bird Island is in Lake Washington (reach G), which is a regulated shoreline under the Shoreline Master Program (SMP) and is within the Shoreline High Intensity Designation, the in-water work would occur below the Ordinary High Water Mark (OHWM),within the Aquatic Shoreline District. Coulon Park is located within the Residential-1 (R-l) zoning designation. DNR took Lead Agency status for the State Environmental Policy Act (SEPA) review and issued a Determination of Non-Significance for the work proposed. The SEPA comment period for the proposal ended on January 15, 2016. • Bird Island Shoreline Restoration Project Page 2 of 7 February 4,2016 • The project proposes to remove the metal and concrete debris that is in the water along the island's shoreline, but not beneath the mud line. Fish mix material will be imported to create shallow water habitat with appropriate sized materials for the migrating juvenile Chinook. The design also includes placement of two engineered log jams on the northern side of the island to increased habitat complexity, control sediment drift, and help prevent future erosion. A ten foot minimum zone of native mixed wetland and riparian species will be planted between the edge of the new shoreline and the edge of the timber pathway. Beyond this zone, areas currently denuded or occupied by invasive species will be cleared and revegetated with native species. Plantings will be integrated into the bank in order to maximize overhanging and riparian vegetation. Larger trees will be planted further upland in order to provide further shading of the shoreline. Planting would also improve structural and species diversity and include native emergent, shrub, and tree species. A temporary irrigation line will be required to sustain the plantings. A connection to the Gene Coulon Memorial Beach Park irrigation system and a small plastic pipe will be attached under the existing bridge. Irrigation pipes will be installed on grade throughout the new plantings. DNR will monitor the success of the new vegetation and replace unsuccessful plantings for five years following the initial planting. The project proposes to extend the boardwalk into a loop to discourage off-path travel and keep visitors moving. The scope of work will include the installation of shallow timber foundations, stringers, and decking. This design maximizes the scenic potential of the location by providing new boardwalk access to the highest point on the island, via a timber path traveling along the northwest shoreline of the island. All new and existing boardwalk will have guardrails on both sides and will be ADA accessible. This concept provides a wider buffer of overhanging vegetation along the shoreline and allows for trees to be planted in the center of the site to provide shading of the shoreline and the boardwalk. The new boardwalk will provide two benches and three educational signs that will tell the story of migrating salmon and educate visitors about the importance of the habitat and the restoration efforts that have been completed on the south end of the lake. The project also proposes to remove a section of the boardwalk that would not be a part of the new loop concept. One wetland, Wetland A, was delineated within the project location. The wetland is 9,750 square feet (0.22 acres). Wetland A consists of shrub and emergent communities that are located along the shoreline of Lake Washington and within a swale that bisects the island. The wetland rating for this wetland is Category II. The City of Renton's recommended buffer range for this wetland is 150 feet. Bird Island encompasses the entire 150-foot wetland buffer area. The upland buffer areas currently consist of a boardwalk, mowed lawns, shrub habitat, or mixed coniferous and deciduous trees. The following are a list of the actions that are described above: • Enhance shallow water habitat by placing approximately 2,700 cubic yards (cy) of substrate enhancement (fish mix, consisting of clean sand and fine gravel, (1,950 cy below OHWL, 750 cy above OHWL)), along the shoreline to increase and enhance juvenile Chinook habitat. Page 2 of 7 • Bird Island Shoreline Restoration Project Page 3 of 7 February 4, 2016 • Construct two engineered log jams (EUs). • Place 12 anchored logs. • • Remove approximately 321 cy of debris from shoreline (weight of 250 tons of soil, sand/gravel, and boulder-sized particles, 525 tons of steel/concrete, representing a 60- to-40% mix of dirt and steel/concrete, respectively) of debris from shoreline, • Removing nonnative or invasive plants to the extent possible. • Plant native, emergent, and/or riparian vegetation along the shoreline and upland to control public access and enhance habitat for other species. • Protect existing native vegetation. • Enhance 24, 270 square feet of shoreline and aquatic habitat, 8,777 square feet of existing wetlands and 3,216 square feet of wetland buffer. • Improve existing public access trail with new railings and increase the boardwalk trail system by 200 lineal feet with a new and improved loop, to replace the existing at grade trail. • Cut fill, set foundations, stringers, deck, and rail comprising 200 feet (1,200 square feet) of new boardwalk. • Remove 30 feet (180 square feet) of existing boardwalk. • Place new educational sign age along boardwalk. • Prevent shoreline erosion or sediment transport to the extent possible. The proposed Bird Island Shoreline Enhancement project includes public access and recreation improvements as well as shoreline and wetland and wetland buffer enhancements. Existing regional parks are an outright permitted use within the R-l zone. Below is Staffs analysis of the project's compliance with the Shoreline Master Program related to the above portions of the proposed enhancement project. Public Access: In accordance with RMC 4-3-090D.4.f, Public Access Requirements by Reach, public access is one element of park functions that should be continued and incorporated in future plans and balanced with goals for recreation and improving ecologic functions. Public access is currently provided onto Bird Island via a timber boardwalk, which provides access to approximately 50 percent of the island's perimeter. Numerous native and non-native species of plants and animals utilize the island for habitat, but this habitat is currently disturbed by virtually unrestricted human access off the designated trail. Erosion and scarps along the shoreline of the island have exposed some of the concrete and steel debriS. As part of the proposed restoration, 30 feet of existing boardwalk would be removed and 200 feet of new boardwalk would be constructed. The new boardwalk would extend into a loop to discourage off-path travel and keep visitors moving. The scope of work will include the installation of shallow timber foundations, stringers, and decking, This design maximizes the scenic potential of the location by providing new boardwalk access to the highest point on the island, via a timber path traveling along the northwest shoreline of the Island. All new and existing boardwalks will have guardrails on both sides and will be ADA accessible. This concept provides a wider buffer for overhanging vegetation along the shoreline and allows for trees to be planted in the center of the site to provide shading of the shoreline and the boardwalk. The new boardwalk will provide two benches and three educational signs that will tell the story of migrating salmon and Page 3 of 7 • Bird Island Shoreline Restoration Project Page 4 017 February 4, 2016 • educate visitors about the importance of the habitat and the restoration efforts that have been completed on the south end of the lake. The proposed project would maintain public access to the island while enhancing the habitat functions through the proposed restoration activities. Vegetation Conservation: Pursuant to RMC 4-3-090F.1.g Buffer Enhancement, buffer enhancement as a separate action may be proposed on any property and may be implemented without full compliance with the standards of this Section; provided, that the project includes a buffer enhancement plan using native vegetation and provides documentation that the enhanced buffer area will maintain or improve the functional attributes of the buffer. Any change to existing nonconforming facilities or use on a site shall meet the provisions for nonconforming sites. The proposal includes shoreline restoration as well as the enhancement of the onsite wetland (Wetland A) and buffer area. A Habitat Report and lake Study, Critical Areas Study, and Restoration plans were submitted with the project application. As previously discussed above, the proposal includes the removal of existing invasive plants and the installation of native plantings within the wetland and buffer areas which encompass the entire island. According to the submitted Habitat Report and lake Study, the proposed enhancement activities would result in no net loss of ecological functions and processes and will provide a functional lift of the habitat on the island. landfill and Excavation: Pursuant to RMC 4-3-090F.2.a Landfill and Excavatian shall only be permitted in conjunction with an approved use or development and allowed with assurance of no net loss of shoreline ecological functions. As previously discussed above, the scope of work for this project includes the removal of debris that is littered around the shoreline (some of which is below the OHWM), removal of invasive plants, native plantings, placement of sediment for shallow water juvenile fish habitat, placement of large wood, and trail improvements. The purpose of the improvements is to improve ecological functions along the shoreline as well as within Wetland A and the associated buffer areas. The proposed enhancements include the placement of approximately 2,700 cy of substrate enhancement (fish mix, consisting of clean sand and fine gravel, (1,950 cy below the OHWL and 750 cy above OHWL)), along the shoreline to increase and enhance juvenile Chinook habitat. In addition, approximately 321 cy of debris would be removed from the shoreline (weight of 250 tons of soil, sand/gravel, and boulder-sized particles, representing a 60-to-40% mix of dirt and steel/concrete respectively). RMC 4-3-090F.2.b provides Criteria for Allowing Landfills and Excavations Below Ordinary High Water Mark, landfills and excavations shall generally be prohibited below the OHWM, except for the following activities, and in conjunction with documentation of no net loss of ecological functions as documented in appropriate technical studies. The applicable criteria is listed below: i. Beach or aquatic substrate replenishment in conjunction with an approved ecological restoration activity; Staff Comment: The purpose of the fill and grading along the island's shareline is to create shallow water habitat for migrating juvenile Chinoak salman by placing approximately 2,700 cy Page 4 01 7 • • Bird Island Shoreline Restoration Project Page 5 of 7 February 4, 2016 of sand and fine gravel. The grading and placement of approximately 358 cy of top soil and mulch an the island will help remove invasive seed stock and improve the quality of soils for new native plants in which to grow. Approximately 16.8 cy of crushed surface base course material will be used to set the new boardwalk foundation. The origin of all the fill will be a clean commercial product specified by the contractor. Total anticipated excavation (upland af OHWL) is estimated to be 33.4 cy.

Basis for the exemption request DNR believes this project is exempt per the "watershed restoration proj ects" category for the shoreline pennit. The projects is primarily designed to improve fish and wildlife habitat, remove impediments to migration of fish, and enhance the fishery resource available for use by all of the citizens of the state. The project will have a no net loss of ecological functions and processes and will provide a functional lift ofthe habitat on the island. Please see the Habitat Report and Lake Study as well . as the Critical Areas Report for more infonnation on the functional lift. Project Narrative Page 2of6 Bird Island Shoreline Enhancement Project • This project is listed as project number C266A on the three year work plan under the Water Resource Inventory Area (WRIA) 8 Chinook Salmon Conservation Plan. This project is a Tier I priority under the WRiA 8 plan due to the project's location in a migratory and rearing corridor for Chinook salmon. This project will accomplish priority actions under the Conservation Plan by increasing overhanging vegetation and removing debris along the shoreline and enhancing important shallow water habitats closest to the mouth of the Cedar River where such habitat is most heavily used by juvenile Chinook salmon (Tabor 2006). Work Schedule The upland work (e.g. trail restoration, plantings) is proposed to occur during the spring of2017 to the extent possible. The in-water work is proposed to occur during the sununer work window between July 2017 to August2017, whenthe lake level is raised by 1.8 feet, and possibly during the winter work window of November 2017 to December 2017. DNR has requested an extension on the beginning and end of the restrictive sununer work window due to the need for additional time to complete all of the in-water work during one mobilization and in one work window to the extent possible. Plantings that will occur below theOHWL will need to be planted following the in-water work. Scheduled maintenance and monitoring as well as regular park maintenance activities will occur following construction. Required Permits DNR intends to apply for the following permits for this project: • SEPA-DNR • Shoreline Exemption-City of Renton • Hydraulic Project Approval-WDFW • 401-DOE " • Nationwide 27-Army Corps of Engineers Current use ofthe site This manmade"island is state-owned aquatic lands managed by the Washington State Department of Natural Resources. The island is located in Gene Coulon Memorial Beach Park and included in a lease that is managed by the City of Renton Parks Department. The project is listed on the WRIA 8 three year work plan. " The property is surrounctedby the harbor limits of Lake Washington on all sides except the south, where it is bordering a small piece of private property on the island's southwest comer. "The island was created by the placement of fill over steel matting commonly known as Marsden matting. The "exact date" of its original. construction is unknown. A timber bridge provides access to the island from the park, becoming a timber boardwalk that provides access to approximately 50% of the island's perimeter. Project Narrative Page 3 of 6 Bird Island Shoreline Enhancement Project • • Numerous native and non-native species of plants and animals utilize the island for habitat, but this habitat is currently disturbed by virtually unrestricted human access off the designated trail. Erosion and scarps along the shoreline of the island have exposed some of the concrete and steel debris. Previous studies and background information include a baseline survey and monitoring survey. The previous studies reported minimal change between 2006 and 2010 at the bluff and waterline, suggesting that shoreline erosion is a relatively slow process These studies were compared with bathymetry received in June, 2015, and confirmed that very little near-shore erosion has occurred in the decade. Beyond the immediate shoreline, Bird Island is surrounded by a shallow submerged area which extends to the north and west from the island. Bird Island is also exposed to wind and wave action in Lake Washington. A coastal engineering analysis was performed to determine.the magnitude of these forces, as well as the possibility of wind and wave forces contributing to site erosion. This analysis concluded that the largest amount of wave energy present at the site is generated by winds blowing from the northwest. As a result, the net sediment drift direction will be from the northwestern tip of the island to the south and eastshorelines of the island. Due to the relatively low energy of waves occurring in Lake Washington, however, the rate of erosion and subsequent drift is low. Drift cells in Lake Washington have not been mapped, so it is unknown if sediment from areas outside the project area will deposit within the area over time . . Special site features Bird Island is in Lake Washington, which is designated asa Type S waterbody under RMC Section 4-3-050 (City of Renton 2015). Regulations for Type S waterbodies are described in RMC 4-3-090, Shoreline Master Program Regulations. Under RMC 4-3-090, Lake Washington is designated a Shoreline of Statewide Significance in the shoreline high-intensity overlay district. The jurisdictional area of shorelines of statewide significance is 200 feet from the OHWM. The lake level is regulated by the locks in Seattle. The OHWMin summer is 21.7 feet and the ordinary low water mark (OL WM, in winter) is 20 feet. One wetland, Wetland A, was delineated within the project location. The wetland is 9,750 square feet, or 0.22 acres. Wetland A consists of shrub and emergent communities that are located along the shoreline of Lake Washington and within a swalethat bisects the island. The wetland rating for this wetland is Category II. The City of Renton's recommended buffer range for this wetland is 150 feet. Bird Island encompasses the entire 150 foot wetland buffer area. The upland buffer areas consist of a boardwalk, mowed lawns, shrub habitat, or mixed comferous and deciduous trees. Please see the Critical Area Report and Habitat Report arid Lake Study for more information about the special featufes of the site. Soil type and drainage conditions Bird Island is a manmade artificial island comprised mostly of unconsolidated fill, Project Narrative Page 4 of 6 Bird Island Shoreline Enhancement Project • including sands, some silty soils in the upland portion of the island, and gravels, cobble, and larger rocks along the shoreline. Total estimated construction cost $786,140 Estimated quantities and type of materials involved if any fill or excavation is proposed The purpose of the fill and grading along the island's shoreline is to create shallow water habitat for migrating juvenile Chinook salmon by placing approximately 2,700 cubic yards of sand and [me gravel. The grading and placement of approximately 358 cubic yards'oftop soil and mulch on the island will help remove invasive seed stock and improve the quality of soils for new native plants in which to grow. Approximately 16.8 cubic yards of crushed surface base course material will be used to set the new boardwalk foundation. The origin of all the fill will be a clean commercial product specified by the contractor. Total anticipated excavation (upland ofOHWL) is estimated to be 33.4 cubic yards.

The ordinary high water mark of Lake Washington varies throughout the year. In the summer, the OHWM is elevation 21. 7 feet, and in the winter it is 20 feet. Project Narrative Page 6 of6 Bird Island Shoreline Enhancement Project ".' Proposal HABITAT REPORT AND LAKE STUDY· Bird Island Shoreline Enhancement Project Prepared by the Washington State Department 6f Natural Resource,s December 9,2015 DEC i il 2015 (,,~,~ "!' f":i~; :,,;_:~H'h'(~;: l~!Id":l l'j\lG ui\'.:·!O"',j Washington Stiate Department of Natural Resources (DNR) in partnership with the City of Renton Community Services. Department is proposing to enhance approximately 525 feet of . shoreline habitat and approximately 0.4 acres of upland habitat with the goal to improve. the migratory and rearing habitat for juvenile Chinook salmon and public access for park users on and around Bird Island. Bird Island is state owned property, managed by the City of Renton Parks Department located in Gene Coulon Memorial Beach Park 1201 LakeWashington Boulevard North, Renton, WA 98056. The following actions are proposed to meet the restoration objectives ... • Enhance shallow water habitat by placing approximately 2,700 cubic yards (cy) of substrate enhancement (fish mix, consisting of clean sand and fine gravel, (1,950 cy below OHWL, 750 cy above OHWL), along the shoreline to increase and enhance juvenile Chinook habitat. . Construct two engineered log jams (ELJs) . • Place 12 anchored logs. Remove apprOXimately 321 cy of debris·from shoreline (weight of 250 tons of soil, sand/gravel, and boulder-sized particles,.525 tons of steel/concrete, representing a 60- to-40% mix of dirt and steel/concrete, respectively} of debris from shoreline • Removing nonnative or invasive plants to the extent possible· • Plant native, emergent, and/or riparian vegetation along the shoreline and upland to control public access and enhance habitat for other species • Protect existing native vegetation • Enhance 8,777 square feet of existing wetlands • Improve existing public access trail with new railings and increase the boardwalk trail system by 200 lineal feet with a new and improved loop • Cut fill, set foundations, stringers, deck, and rail comprising 200 feet (1,200 square feet) of new boardwalk • Remove 30 feet (180 square feet) of existing boardwalk • Place new educational signage along boardwalk • Prevent shoreline erosion or sediment transport to the extent possible Current Site Conditions Bird Island is a manmade island that is state-owned aquatic lands managed by the Washington State Department of Natural Resources. The island is located in Gene Coulon Memorial Beach Park and included in a lease that is managed by the City of Renton Parks Department. The project is listed on the WRIA 8 three year work plan. The property is surrounded by the harbor limits of Lake WaShington on all sides except the south, where it is bordering a small piece of private property on the island's southwest corner. The island was created by the placement of fill over steel matting commonly known as Marsden matting. The exact date of its original construction is unknown. A timber bridge provides access Habitat Report and Lake Study Bird Island Shoreline Enhancement Project to the island from the park, becoming a timber boardwalk that provides access to approximately 50% ·of the island's perimeter. Numerous nativei and non'native species of plants and animals utilize the island for habitat, but this habitat is currently disturbed by virtually unrestricted human access off the designated trail. Erosion and scarps along the shoreline of the island have exposed some of the concrete and steel debris. Current Habitat Conditions The habitat is currently degraded due to shoreline erosion, uncontrolled public access, concrete and metal shoreline debris. and invasive species. Weeds of concern include the yellow-flag iris (Iris pseudacorus), reed canarygrass (Pha/aris aumdianacea), Himalayan blackberry (Rubus armeniacus),all Class C Noxious Weed in King County, and tansy ragwort (Seneciojacobaea) a Class B Noxious Weed in King County. There are 25+ deciduous trees growing on the island including Pacific willow (Sa/ix/ucida), Oregon ash (Fraxinus /atifolia), red alder (A/nus rubra), weeping willow (Salix baby/onica) and two cherry trees. A variety of emergent, shrubs,. and grasses are growing on the property including hedge nettle (Stachys sp.), tall mannagrass (G/yceria e/ata), bentgrass (Agrostis sp.), snowberry (Symphoricarpos a/bus), and Nootka ros!,! (rosa nutkana). Bird Island is in Lake Washington, which is designated as .a Type S waterbody under RMC Section 4-3-050 (City of Renton 2015). Regulations for Type S waterbodiesare described in RMC 4 C3-090, Shoreline Master Program Regulations. Under RMC 4-3-090, Lake Washington is designated a Shoreline of Statewide Significance in the shoreline high-intensity overlay district. The jurisdictional area of shorelines of statewide significance is 200 feet from the OHWM. The lake level is regulated by the locks in Seattle. The OHWM in summer is 21.7 feet and the ordinary low water mark (OLWM, in winter) is 20 feet. This site is part of the Pacific Flyway, a north-south seasonal migration route for many bird species. South Lake Washington is also a migratory and rearing corridor for Chinook salmon (Oncorhynchus tshawytscha). Sockeye· salmon (Oncorhynchus nerka), Puget Sound coho salmon (Oncorhynchus kisutch), and the Puget Soundsteelhead (Oncorhynchus mykiss) are also found at the site. Juvenile Chinook salmon are found in the littoral zone of Lake Washington between January and July and will most likely congregate close to the shores near the mouth of the Cedar River in the beginning of February to the end of May (Tabor 2006). The project site is approximately 860 meters away from the mouth of the Cedar River. The shoreline of the project site has the potential to provide important rearing habitat for juvenile Chinook salmon due to its close proximity to the mouth of the Cedar River. Other wildlife found at the site include; sculpin, threespine stickleback, yellow perch, freshwater shrimp, bull trout, blue heron, and bald eagle. Below is a table that lists all of the Washington State Department of Fish and Wildlife (WDFW) Priority Species. A lake fringe wetland is located on the site and is a WDFW priority habitat. See the Critical Area Study for more information on the wetland delineation.

Invasive plants will be removed with. hand tools. Monitoring of the invasive plants will occur and adaptive· management strategies will be developed to control invasive plants that continue to grow on the site. Plant site The objective of this proposal is to plant four different zones of native vegetation. Zone 1 is approximately 3,452 square feet of lake fringe emergent. This zone is located below the Ordinary High Water Mark and includes bulrush and sedge species. Zone 2 is approximately 1,161 square feet of slough emergent wetland. This zone is a slough area that runs across the center of the island and is wet in the winter and dry in the summer. This area will be planted with rushes and sedges. Zone 3 is approximately 4,164 square feet and runs along the islands shoreline. This area will be planted with willow live stakes and dogwood. Zone 4 is approximately 3,216 square feet of upland shrub and trees. This area located on the inside of the island will be a mix of native shrubs and conifers. Planting will occur by hand using appropriate hand tools to dig holes and place the plants in the ground: Small machinery may be used to grub land .and place compost and mulch during planting. . Remove existing debris and place fine grained saM and gravel along shoreline Approximately 321 cubic yards of metal and concrete shoreline debris from up to 6 inches below the surface will be removed from around Bird Island's shoreline. Once the debris has been removed a contractor will place approximately 2,700 cubic yards of fine gravel and sand along the shoreline to create shallow water habitat. Habttat Report and Lake Study 3 Bird Island Shoreline Enhancement Project In-water based methods may be utilized to complete the placement of the material. Equipment may include a barge, loader, dredge bucket, and conveyor belt. The source of the material is not yet determined. Materials will be a commercial project with high quality suitable for fish restoration projects in the lake environment. The material will be placed along the shoreline to create shallow water habitat. and to me.et the existing slope; Place Engineered Log Jams and Anchored Logs along shoreline· Sixteen pile structure logs and 26 root wad logs will be placed along the shoreline to build two engineered log jams and 12·anchored logs will be placedalong·the shoreline. Equip.ment may include a Vibratory hammer, load; excavator, or other small machinery. The engineered logs jams will protect the. beach from wave action and sediment transport. The anchored logs will help minimize erosion. The wood will create a m·ore complex area of refuge for migrating juvenile Chinook. . . Construct ·200 feet of new boardwalk and remove 30 feet of existing boardwalk This work will occur within the wetland buffer. Areas will be cut and filled to meet the appropriate grade to set foundations, approximately. 20 sleepers, stringers, and install the deck and railing. Approximately 33.4 cubic yards of excavation will occur and ;16.8 cubic yards of crushed surface base course material will be used to set the boardwalk foundation. Small equipment such as hammers and saws will be used. Other small machinery may be used to transport and place the materials onto the site, New educational signage and benches will also be installed as part of the boardwalk construction. Thirty feet (180 square feet) of existing boardwalk will be removed. Impact Evaluation The project will have a no net loss of ecological functions and processes and will provide a functional lift 'of the habitat on the island. Shore/ands The purpose of this proposal is to enhance the habitat at the site. In order to restore the area there will be short term impacts during the construction. The projects construction will temporarily affect sediment, substrate embeddedness, large woody debris, and refugia but will result in long-term improvements to other target indicators, including large woody debris, refugia habitat, and the function of riparian reserves. The short term impacts of the project construction are not likely to adversely affect the priority species that utilize the area. The removal of invasive plants and grading on the upland portion of the site will reestablish the area with native vegetation and immensely improve the current habitat conditions. The short term impacts of placing the beach material will provide long term benefits by creating shallOW water habitat for migrating salmon that rear along the projects shoreline. Methods will be developed to avoid impacts or minimize the short term impacts. Best Management Practices (BMPs) will be in place during construction. In water work will only occur during the WDFW permitted windows. A turbidity curtain will be placed in the lake surrounding the construction area. The contractor will be required to have a Spill Prevention Control and Countermeasures plan in place during the project. The native vegetation will remain Habitat Report and Lake Study 4 Bird Island Shoreline Enhancement Project ~--------------------------------_._- on site and be protected during construction. The contractor will be required to control erosion, runoff and turbidity: An erosion and sediment control plan will be in place during the construction of the project. BMPs such.as the following may be in place to minimize disturbance: • Designated layout area • Buffer zones for native vegetation that will remain • Stabilize exposed soils • Spill Prevention and Control Plan • Coir logs • Straw waddles . • Turbidity Curtains. WetiandlWetiand Buffer A 9,750 square foot Category II lake fringe wetland is located on Bird Island. The City of Renton Municipal Codes regulates that this type of wetland has a 150 foot buffer. Due to the size of the island the 150 foot buffer encompasses the entire island. The riparian wetland on the north and west of the island has eroded and much of the slough wetland is lacking vegetation or is invaded with noxious weeds. There will be no permanent adverse impacts to the wetland. The existing significantly degraded wetland will be enhanced with new native plantings. The size of the existing wetland will increase to 13,400 square feet once the project is complete. . Permanent impacts to the upland wetland butter will occur with the additional construction of the 200 feet (1,200 square feet) of boardwalk trail. The new boardwalk will not be located within the wetland, however it will be located in the wetland buffer due to the 150 fool buffer encompassing the entire island. The new boardwalk trail will not significantly affect the function of the wetland 'or 150 foot buffer. The location forthe new trail currently lacks vegetation. The public is currently walking over the entire island. The new boardwalk system will encourage the public to stay on the boardwalk loop system with new benches and educationalsignage and viewpoints out to the Lake and the enhanced shoreline and wetland. The intention of the new boardwalk design is to allow the public to enjoy.the site and at the same time protect the important wetland and shoreline habitat features. ' - The project will remove 30 feet of eXisting boardwalk creating 180 square feet of new vegetated habitat. The project will enhance 8,777 square feet of the wetland and 3,216 square feet of wetland buffer. A total of 11,993 square feet 'of Bird Island will be planted with native vegetation providing a significant functional list to the aquatic habitat on the island. Please see the Critical Area Study for further information on the functional lift analysis. The BMPs listed above will be in place to protect the wetland during the constnuction of the project. All the existing trees will remain on the site and native vegetation will be protected to the extent possible during construction of the project. A temporary irrigation system will be installed on the island to help ensure plant survival. The new vegetation will be monitored for five years following the completion of the project to assure healthy and viable plants. Habitat Analysis Current conditions along the southern shoreline of Lake Washington include extensive shoreline armoring, paving, and buildings in close proximity to the shoreline. Over 70 percent of the Lake Washington shoreline is retained by either rip-rap or bulkheads. Moreover, elimination of large Habitat Report and Lake Study 5 Bird Island Shoreline Enhancement Project . .. woody debris and the introduction of nonnative species are impacting the lake's ecosystem (Kerwin 2001). This common development along, the lake has caused .the loss of gently sloped beaches, woody debris, and overhanging vegetation that provide important habitat'for migrating juvenile Chinook salmon. Studies have shown that higher numbers of juvenile Chinook are found along unarmored shorelines versus'armored shorelines (Tabor 2006). All ofthese uses along the lake I,imit the opportunities to provide improved shallOW water habitat for juvenile salmon rearing. This project provides a unique restoration opportunity, along the southern shoreline of Lake Washington that will markedly improve rearing conditions for juvenile salmonids outmigrating from the Cedar River. The project site is in close proximity to the mouth of the Cedar River and provides a relatively long stretch of shoreline where shallow water and riparian conditions can readily be enhanced to support'juvenile salmon rearing. The proximity to the Cedar River is a key attribute of this site because fish utilization research has documented the greater outmigrating salmon use of shorelines closer to the river (Tabor et al. 2004 and 2006): Tabor et al. (2006) documented a logarithmic relationship between the distance to the Cedar River and the density of juvenile Chinook salmon between February and May: The project site is 860 meters from the mouth of the Cedar where Chinook densities increase sharply: According,to the WRIA 8 Chinook Salmon Conservation Plan the following are habitat limiting factors for Chinook salmon in Lake Washington. • shoreline complexity • shoreline vegetation • ,degraded water quality • introduced plant species The Bird Island Shoreline Enhancement Project is addressing the Lake Washington habitat limiting factors by designing a project that will provide a more complex shoreline with overhanging native vegetation, woody debris, and shallow beach habitat. These shoreline habitat conditions are particularly important for juvenile Chinook from the Cedar River population (WRIA 8 Chinook Salmon Conservation Plan). The proposed shallow shoreline will provide an area for juvenile Chinook salmon to rear in and reduce the risk of predation that currently exists with the debris and lack of shoreline vegetation. Initial studies at the neighboring South Lake Washington Shoreline Restoration site indicated that changing the substrate size to sand and gravel from cobble improved habitat conditions for juvenile Chinook salmon. (Tabor 2015). Restoration sites close to the mouth of the Cedar River are likely to have a higher chance of success than northern sites because juvenile Chinook salmon are substantially more abundant near the mouth of the Cedar River than at more northerly sites (Tabor 2006). Various surveys of Lake Washington indicate that overhead vegetative cover with or without small woody debris is an important habitat feature for juvenile Chinook salmon. Currently the site provides a limited amount of this type of habitat feature. The project will increase the Habijat Report and Lake Study 6 Bird Island Shoreline Enhancement Project -., ,_ .. overhead cover along the shoreline which may provide juvenile Chinook visual refuge from fish and bird predators (Tabor 2006). . . . With the completion of this proposal the habitat will be improved for all of the priority species. Once the shoreline is restored it will provide components that create functional salmon habitat conditions with a naturally sloped shoreline, native vegetation, large woody debris, and. appropriate sized substrates. All of these functions help meet the goals serin the WRIA 8 Chinook Salmon ConsBlVation Plan, which states that the restoration of Lake Washington is a high priority for regional restoration efforts and the remaining areas with sandy shallow-water habitat, overhanging vegetation, and large woody debris should be protected and maintained. Please also see the Critical Area Study (2015) for more information on the wetland and functional lift analysis.

The scope of work includes removal of debris that is littered around the shoreline, removal of invasive plants, native planting, placement of sediment for shallow water habitat, placement of large wood, and trail improvements. While this application is tied in the permit system to the Coulon Park parcel, the project site itself is actually located just outside of the City limits on DNR land and does not have a parcel number of its own. Bird Island is in Lake Washington (reach G). which is a regulated shoreline under the Shoreline Master Program (SMP) and is within the Shoreline High Intensity Designation, the in-water work would occur below the Ordinary High Water Mark (OHWM),within the Aquatic Shoreline District. Coulon Park is located within the Residential-l (R-l) zoning designation. DNR took Lead Agency status for the State Environmental Policy Act (SEPA) review and issued a Determination of Non-Significance for the work proposed. The SEPA comment period for the proposal ended on January 15, 2016. -J.f<.l. I I'" .-; ni 2. '1/, fut r, P) r , : "', j.~:-.: ;~., I I -,-.. 1-, I' 111~1~"'\J"-'~~ , \, .• V' i , ..

Proposal DNR in partnership with the City of Renton Community Services Department is proposing to enhance approximately 525 feet of shoreline habitat and approximately 0.4 acres of upland habitat with the goal to improve the migratory and rearing habitat for juvenile Chinook salmon and public access for park users. The scope of work includes removal of debris that is littered around the shoreline, removal of invasive plants, native planting, placement of sediment for shallow water habitat, placement of large wood, and trail improvements. The project proposes to remove the metal and concrete debris that is in the water along the islands shoreline, but not beneath the mudline. Fish mix material will be imported to create shallow water habitat with appropriate sized materials for the migrating juvenile Chinook. The design also includes placement of two engineered logjams on the northern side ofthe island to increase habitat complexity, control sediment drift, and help prevent future erosion. A ten foot minimum zone of native mixed wetland and riparian species will be planted between the edge of the new shoreline and the edge of the timber pathway. Beyond this zone, areas currently denuded or occupied by invasive species will be cleared and revegetated with native species. Plantings will be integrated into the bank in order to maximize overhanging and riparian vegetation. Larger trees will be planted further upland in order to provide further shading of the shoreline. Planting would also improve structural and species diversity and include native emergent, shrub, and tree species. A temporary irrigation line will be required to sustain the plantings. A connection to the Gene Coulon Memorial Beach Park irrigation system and a small plastic pipe will be attached under the existing bridge. Irrigation pipes will be installed on grade throughout the new plantings. DNR will monitor the success of the new vegetation and replace unsuccessful plantings for five years following the initial planting. The project proposes to extend the boardwalk into a loop to discourage off-path travel and keep visitors moving. The scope of work will include the installation of shallow timber foundations, stringers, and decking. This design maximizes the scenic potential of the location by providing new boardwalk access to the highest point on the island, via a timber path traveling along the northwest shoreline of the Island. All new and existing boardwalk will have guardrails on both .• sides and will be ADA accessible. This concept provides a wider buffer of overhanging.:;;~;sl;N' PLANN,I"o t Project Narrative Page lof6 Bird Island Shoreline Enhancement Project • • vegetation along the shoreline and allows for trees to be planted in the center of the site to provide shading of the shoreline and the boardwalk. The new boardwalk will provide two benches and three educational signs that will tell the story of the migrating salmon and educate visitors about the importance of the habitat and the restoration efforts that have been completed on the south end of the lake. The project also proposes to remove a section of the boardwalk that would not be a part of the new loop concept. The following are a list of the actions that are described above. • Enhance shallow water habitat by placing approximately 2,700 cubic yards (cy) of substrate enhancement (fish mix, consisting of clean sand and fine gravel, (1,950 cy below OHWL, 750 cy above OHWL), along the shoreline to increase and enhance juvenile Chinook habitat. . • Construct two engineered logjams (ELJs) • Place 12 anchored logs • Remove approximately 321 cy of debris from shoreline (weight of 250 tons of soil, sand/gravel, and boulder-sized particles, 525 tons of steel/concrete, representing a 60-to- 40% mix of dirt and steel/concrete, respectively) of debris from shoreline • Removing nonnative or invasive plants to the extent possible • Plant native, emergent, and/or riparian vegetation along the shoreline and upland to control public access and enhance habitat for other species • Protect existing native vegetation • Enhance 8,777 square feet of existing wetlands • Improve existing public access trail with new railings and increase the boardwalk trail system by 200 lineal feet with a new and improved loop • Cut fill, set foundations, stringers, deck, and rail comprising 200 feet (1,200 square feet) of new boardwalk • Remove 30 feet (180 square feet) of existing boardwalk • Place new educational signage along boardwalk • Prevent shoreline erosion or sediment transport to the extent possible See the attached JARP A design drawings for additional information on the project. Basis for the exemption request DNR believes this project is exempt per the "watershed restoration projects" category for the shoreline permit. The projects is primarily designed to improve fish and wildlife habitat, remove impediments to migration of fish, and enhance the fishery resource available for use by all ofthe citizeris of the state. The project will have a no net loss of ecological functions and processes and will provide a functional lift of the habitat on the island. Please see .the Habitat Report and Lake Study as well as the Critical Areas Report for more information on the functional lift. Project Narrative Page 2 of 6 Bird Island Shoreline Enhancement Project • • This project is listed as project number C266A on the three year work plan under the Water Resource Inventory Area (WRIA) 8 Chinook Salmon Conservation Plan. This project is a Tier 1 priority under the WRIA 8 plan due to the project's location in a migratory and rearing corridor for Chinook salmon. This project will accomplish priority actions under the Conservation Plan by increasing overhanging vegetation and removing debris along the shoreline and enhancing important shallow water habitats closest to the mouth of the Cedar River where such habitat is most heavily used by juvenile Chinook salmon (Tabor 2006). Work Schedule The upland work (e.g. trail restoration, plantings) is proposed to occur during the spring of2017 to the extent possible. The in-water work is proposed to occur during the summer work window between July 2017 to August 2017, when the lake level is raised by 1.8 feet, and possibly during the winter work window of November 2017 to December 2017. DNR has requested an extension on the beginning and end of the restrictive summer work window due to the need for additional time to complete all of the in-water work during one mobilization and in one work window to the extent possible. Plantings that will occur below the OHWL will need to be planted following the in-water work. Scheduled maintenance and monitoring as well as regular park maintenance activities will occur following construction. Required Permits DNR intends to apply for the following permits for this project: • SEPA-DNR • Shoreline Exemption-City of Renton • Hydraulic Project Approval-WDFW . • 401-DOE • Nationwide 27-Army Corps of Engineers Current use of the site This manmade island is state-owned aquatic lands managed by the Washington State Department of Natural Resources. The island is located in Gene Coulon Memorial Beach Park and included in a lease that is managed by the City of Renton Parks Department. The project is listed on the WRIA 8 three year work plan. The property is surrounded by the harbor limits of Lake Washington on all sides except the south, where it is bordering a small piece of private property on the island's southwest comer. The island was created by the placement of fill over steel matting commonly known as Marsden matting. The exact date of its original construction is unknown. A timber bridge provides access to the island from the park, becoming a timber boardwalk that provides access to approximately 50% of the island's perimeter. Project Narrative Page 30f6 . Bird Island Shoreline Enhancement Project • • Numerous native and non-native species of plants and animals utilize the island for habitat, but this habitat is currently disturbed by virtually unrestricted human access off the designated trail. Erosion and scarps along the shoreline of the island have exposed some of the concrete and steel debris. Previous studies and background information include a baseline survey and monitoring survey. The previous studies reported minimal change between 2006 and 2010 at the bluff and waterline, suggesting that shoreline erosion is a relatively slow process These studies were compared with bathymetry received in June, 2015, and confirmed that very little near-shore erosion has occurred in the decade. Beyond the immediate shoreline, Bird Island is surrounded by a shallow submerged area which extends to the north and west from the island. Bird Island is also exposed to wind and wave action in Lake Washington. A coastal engineering analysis was performed to determine the magnitude of these forces, as well as the possibility of wind and wave forces contributing to site erosion. This analysis concluded that the largest . amount of wave energy present at the site is generated by winds blowing from the northwest. As a result, the net sediment drift direction will be from the northwestern tip of the island to the south and east shorelines ofthe island. Due to the relatively low energy of waves occurring in Lake Washington, however, the rate of erosion and subsequent drift is low. Drift cells in Lake Washington have not been mapped, so it is unknown if sediment from areas outside the project area will deposit within the area over time .• Special site features Bird Island is in Lake Washington, which is designated as a Type S waterbody under RMC Section 4-3-050 (City of Renton 2015). Regulations for Type S waterbodies are described in RMC 4-3-090, Shoreline Master Program Regulations. Under RMC 4-3-090, Lake Washington is designated a Shoreline of Statewide Significance in the shoreline high-intensity overlay district. The jurisdictional area of shorelines of statewide significance is 200 feet from the OHWM. The lake level is regulated by the locks in Seattle. The OHWM in summer is 21.7 feet and the ordinary low water mark (OL WM, in winter) is 20 feet. One wetland, Wetland A, was delineated within the project location. The wetland is 9,750 square feet, or 0.22 acres. Wetland A consists of shrub and emergent communities that are located along the shoreline of Lake Washington and within a swale that bisects the island. The wetland rating for this wetland is Category II. The City of Renton's recommended buffer range for this wetland is 150 feet. Bird Island' encompasses the entire 150 foot wetland buffer area. The upland buffer areaS consist of a boardwalk, mowed lawns, shrub habitat, or mixed coniferous and deciduous trees. Please see the Critical Area Report and Habitat Report and Lake Study for more information about the special features of the site. Soil type and drainage conditions Bird Island is a manmade artificial island comprised mostly of unconsolidated fill, Project Narrative Page 4 of 6 Bird Island Shoreline Enhancement Project • including sands, some silty soils in the upland portion of the island, and gravels, cobble, and larger rocks along the shoreline. Total estimated construction cost $786,140 Estimated quantities and type of materials involved if any fill or excavation is proposed The purpose of the fill and grading along the island's shoreline is to create shallow water habitat for migrating juvenile Chinook salmon by placing approximately 2,700 cubic yards of sand and fine gravel. The grading and placement of approximately 358 cubic yards of top soil and mulch on the island will help remove invasive seed stock and improve the quality of soils for new native plants in which to grow. Approximately 16.8 cubic yards of crushed surface base course material will be used to set the new boardwalk foundation. The origin of all the fill will be a clean commercial product specified by the contractor. Total anticipated excavation (upland ofOHWL) is estimated to be 33.4 cubic yards. This excavation may be needed to meet the appropriate grades for the construction of the new boardwalk.

Numerous native and non-native species of plants and animals utilize the island for habitat, but this habitat is currently disturbed by virtually unrestricted human access off the designated trail. Erosion and scarps along the shoreline of the island have exposed some of the concrete and steel debris. Current Habitat Conditions The habitat is currently degraded due to shoreline erosion, uncontrolled public access, concrete and metal shoreline debris, and invasive species, Weeds of concern include the yellow-flag iris (Iris pseudacorus), reed canarygrass (Pha/aris aurndianacea), Himalayan blackberry (Rubus armeniacus), all Class C Noxious Weed in King County, and tansy ragwort (Seneciojacobaea) a Class B Noxious Weed in King County. There are 25+ deciduous trees growing on the island including Pacific willow (Salix /ucida), Oregon ash (Fraxinus /atifolia), red alder (A/nus rubra), weeping willow (Salix baby/onica) and two cherry trees. A variety of emergent, shrubs, and grasses are growing on the property including hedge nettle (Stachys sp.), tall mannagrass (G/yceria e/ata), bentgrass (Agrostis sp.), snowberry (Symphoricarpos a/bus), and Nootka rose (rosa nutkana). Bird Island is in Lake Washington, which is design;lted as a Type S waterbody under RMC Section 4-3-050 (City of Renton 2015). Regulations for Type S waterbodies are described in RMC 4-3-090, Shoreline Master Program Regulations. Under RMC 4-3-090, Lake Washington is designated a Shoreline of Statewide Significance in the shoreline high-intensity overlay district. The jurisdictional area of shorelines of statewide significance is 200 feet from the OHWM. The lake level is regulated by the locks in Seattle. The OHWM in summer is21.7 feet and the ordinary low water mark (OLWM, in winter) is 20 feet. This site is part of the Pacific Flyway, a north-south seasonal migration route for many bird species. South Lake Washington is also a migratory and rearing corridor for Chinook salmon (Oncorhynchus tshawytscha). Sockeye salmon (Oncorhynchus nerka), Puget Sound coho salmon (Oncorhynchus kisutch), and the Puget Sound steelhead (Oncorhynchus mykiss) are also found at the site. Juvenile Chinook salmon are found in the littoral zone of Lake Washington between January and July and will most likely congregate close to the shores near the mouth of the Cedar River in the beginning of February to the end of May (Tabor 2006). The project site is approximately 860 meters away from the mouth of the Cedar River. The shoreline of the project site has the potential to provide important rearing habitat for juvenile Chinook salmon due to its close proximity to the mouth of the Cedar River. Other wildlife found at the site include; sculpin, threespine stickleback, yellow perch, freshwater shrimp, bull trout, blue heron, and bald eagle. Below is a table that lists all of the Washington State Department of Fish and Wildlife (WDFW) Priority Species. A lake fringe wetland is located on the site and is a WDFW priority habitat.

Invasive plants will be removed with hand tools. Monitoring of the invasive plants will occur and adaptive management strategies will be developed to control invasive plants that continue to grow on the site. Plant site The objective of this proposal is to plant four different zones of native vegetation. Zone 1 is approximately 3,452 square feet of lake fringe emergent. This zone is located below the Ordinary High Water Mark and includes bulrush and sedge species. Zone 2 is approximately 1,161 square feet of slough emergent wetland. This zone is a slough area that runs across the center of the island and is wet in the winter and dry in the summer. This area will be planted with rushes and sedges. Zone 3 is approximately 4,164 square feet and runs along the islands shoreline. This area will be planted with willow live stakes and dogwood. Zone 4 is approximately 3,216 square feet of upland shrub and trees. This area located on the inside of the island will be a mix of native shrubs and conifers. Planting will occur by hand using appropriate hand tools to dig holes and place the plants in the ground. Small machinery may be used to grub land and place compost and mulch during planting. Remove existing debris and place fine grained sand and gravel along shoreline Approximately 321 cubic yards of metal and concrete shoreline debris from up to 6 inches below the surface will be removed from around Bird Island's shoreline. Once the debris has been removed a contractor will place approximately 2,700 cubic yards of fine gravel and sand along the shoreline to create shallow water habitat. Habitat Report and Lake Study 3 Bird Island Shoreline Enhancement Project • • In-water based methods may be utilized to complete the placement of the material. Equipment may include a barge, loader, dredge bucket, and conveyor belt. The source of the material is not yet determined. Materials will be a commercial project with high quality suitable for fish restoration projects in the lake environment. The material will be placed along the shoreline to create shallow water habitat and to meet the existing slope. Place Engineered Log Jams and Anchored Logs along shoreline Sixteen pile structure logs and 26 root wad logs will be placed along the shoreline to build two engineered log jams and 12 anchored logs will be placed along the shoreline. Equipment may include a vibratory hammer, load, excavator, or other small machinery. The engineered logs jams will protect the beach from wave action and sediment transport. The anchored logs will help minimize erosion. The wood will create a more complex area of refuge for migrating juvenile Chinook. Construct 200 feet of new boardwalk and remove 30 feet of existing boardwalk This work will occur within the wetland buffer. Areas will be cut and filled to meet the appropriate grade to set foundations, approximately 20 sleepers, stringers, and install the deck and railing. Approximately 33.4 cubic yards of excavation will occur and 16.8 cubic yards of crushed surface base course material will be used to set the boardwalk foundation. Small equipment such as hammers and saws will be used. Other small machinery may be used to transport and place the materials onto the site. New educational signage and benches will also be installed as part of the boardwalk construction. Thirty feet (180 square feet) of existing boardwalk will be removed. Impact Evaluation The project will have a no net loss of ecological functions and processes and will provide a functional lift of the habitat on the island. Shorelands The purpose of this proposal is to enhance the habitat at the site. In order to restore the area there will be short term impacts during the construction. The projects construction will . temporarily affect sediment, substrate embeddedness, large woody debris, and refugia but will result in long-term improvements to other target indicators, including large woody debris, refugia habitat, and the function of riparian reserves. The short term impacts of the project construction are not likely to adversely affect the priority species that utilize the area. The removal of invasive plants and grading on the upland portion of the site will reestablish the area with native vegetation and immensely improve the current habitat conditions. The short term impacts of placing the beach material will provide long term benefits by creating shallow water habitat for migrating salmon that rear along the projects shoreline. Methods will be developed to avoid impacts or minimize the short term impacts. Best Management Practices (BMPs) will be in place during construction. In water work will only occur during the WDFW permitted windows. A turbidity curtain will be placed in the lake surrounding the construction area. The contractor will be required to have a Spill Prevention Control and Countermeasures plan in place during the project. The native vegetation will remain Habitat Report and Lake Study 4 Bird Island Shoreline Enhancement Project ------------------------------- • • on site and be protected during construction. The contractor will be required to control erosion, runoff and turbidity. An erosion and sediment control plan will be in place during the construction of the project. BMPs such as the following may be in place to minimize disturbance: • Designated layout area • Buffer zones for native vegetation that will remain • Stabilize exposed soils • Spill Prevention and Control Plan • Coir logs • Straw waddles • Turbidity Curtains WetlandlWetland Buffer A 9,750 square foot Category II lake fringe wetland is located on Bird Island. The City of Renton Municipal Codes regulates that this type of wetland has a 150 foot buffer. Due to the size of the island the 150 foot buffer encompasses the entire island. The riparian wetland on the north and west of the island has eroded and much of the slough wetland is lacking vegetation or is invaded with noxious weeds. There will be no permanent adverse impacts to the wetland. The existing significantly degraded wetland will be enhanced with new native plantings. The size of the existing wetland will increase to 13,400 square feet once the project is complete. Permanent impacts to the upland wetland butter will occur with the additional construction of the 200 feet (1,200 square feet) of boardwalk trail. The new boardwalk will not be located within the wetland, however it will be located in the wetland buffer due to the 150 foot' buffer encompassing the entire island. The new boardwalk trail will not significantly affect the function of the wetland or 150 foot buffer. The location for the new trail currently lacks vegetation. The public is currently walking over the entire island. The new boardwalk system will encourage the public to stay on the boardwalk loop system with new benches and educational signage and viewpoints out to the Lake and the enhanced shoreline and wetland. The intention of the new boardwalk design is to allow the public to enjoy the site and at the same time protect the important wetland and shoreline habitat features. The project will remove 30 feet of existing boardwalk creating 180 square feet of new vegetated habitat. The project will enhance 8,777 square feet of the wetland and 3,216 square feet of wetland buffer. A total of 11,993 square feet of Bird Island will be planted with native vegetation providing a significant functional list to the aquatic habitat on the island. Please see the Critical Area Study for further information on the functional lift analysis. The BMPs listed above will be in place to protect the wetland during the construction of the project. All the existing trees will remain on the site and native vegetation will be protected to the extent possible during construction of the project. A t~mporary irrigation system will be installed on the island to help ensure plant survival. The new vegetation will be monitored for five years following the completion of the project to assure healthy and viable plants. Habitat Analysis Current conditions along the southern shoreline of Lake Washington include extensive shoreline armorin9, paving, and buildings in close proximity to the shoreline. Over 70 percent of the Lake Washington shoreline is retained by either rip-rap or bulkheads. Moreover, elimination of large Habitat Report and Lake Study 5 Bird Island Shoreline Enhancement Project • • woody debris and the introduction of nonnative species are impacting the lake's ecosystem (Kerwin 2001). This common development along the lake has caused the loss of gently sloped beaches, woody debris, and overhanging vegetation that provide important habitat for migrating juvenile Chinook salmon. Studies have shown that higher numbers of juvenile Chinook are found along unarmored shorelines versus armored shorelines (Tabor 2006). All of these uses along the lake limit the opportunities to provide improved shallow water habitat for juvenile salmon rearing. This project provides a unique restoration opportunity along the southern shoreline of Lake Washington that will markedly improve rearing conditions for juvenile salrrionids outmigrating from the Cedar River. The project site is in close proximity to the mouth of the Cedar River and provides a relatively long stretch of shoreline where shallow water and riparian conditions can readily be enhanced to support juvenile salmon rearing. The proximity to the Cedar River is a key attribute of this site because fish utilization research has documented the greater outmigrating salmon use of shorelines closer to the river (Tabor et al. 2004 and 2006). Tabor et al. (2006) documented a logarithmic relationship between the distance to the Cedar River and the density of juvenile Chinook salmon between February and May. The project site is 860 meters from the mouth of the Cedar where Chinook densities increase sharply. According to the WRIA 8 Chinook Salmon Conservation Plan the following are habitat limiting factors for Chinook salmon in Lake Washington. • shoreline complexity • shoreline vegetation • degraded water quality • introduced plant species The Bird Island Shoreline Enhancement Project is addressing the Lake Washington habitat limiting factors by designing a project that will provide a more complex shoreline with overhanging native vegetation, woody debris, and shallow beach habitat. These shoreline habitat conditions are particularly important for juvenile Chinook from the Cedar River population (WRIA 8 Chinook Salmon Conservation Plan). The proposed shallow shoreline will provide an area for juvenile Chinook salmon to rear in and reduce the risk of predation that currently exists with the debris and lack of shoreline vegetation. Initial studies at the neighboring South Lake Washington Shoreline Restoration site indicated that changing the substrate size to sand and gravel from cobble improved habitat conditions for juvenile Chinook salmon. (Tabor 2015). Restoration sites close to the mouth of the Cedar River are likely to have a higher chance of success than northern sites because juvenile Chinook salmon are substantially more abundant near the mouth of the Cedar River than at more northerly sites (Tabor 2006). Various surveys of Lake Washington indicate that overhead vegetative cover with or without small woody debris is an important habitat feature for juvenile Chinook salmon. Currently the site provides a limited amount of this type of habitat feature. The project will increase the Habitat Report and Lake Study 6 Bird Island Shoreline Enhancement Project • • overhead cover along the shoreline which may provide juvenile Chinook visual refuge from fish and bird predators (Tabor 2006). With the completion of this proposal the habitat will be improved for all of the priority species. Once the shoreline is restored it will provide components that create functional salmon habitat conditions with a naturally sloped shoreline, native vegetation, large woody debris, and appropriate sized substrates. All of these functions help meet the goals set in the WRIA 8 Chinook Salmon Conservation Plan, which states that the restoration of Lake Washington is a high priority for regional restoration efforts and the remaining areas with sandy shallow-water habitat, overhanging vegetation, and large woody debris should be protected and maintained. Please also see the Critical Area Study (2015) for more information on the wetland and functional lift analysis.

Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Approximately 11,883 square feat of Bird Island will be replanted In order to remove Invasive species and Incraase native species cover. Thirty feat (180 square feat) of exletlng boardwalk will be removed and 200. feat of new' boardwalk will be Inatelled. Approximately 1,020 square feat of area will be cleared and greded to construct the new boardwalk. These activities have the potential to cause minor and temporary erosion. Some temporary turbidity may occur during Itt., 20/4 4 • • placement of sand and fine gravel along the shoreline. All efforta· will be taken to minimize this temporary disturbance using turbidity curtains, straw wattles to mitigate erosion, and other Best Management Practices (BMPs) as needed. OVer time the sediment placed to create the habitat bench along the ahorellne could ahift due to littoral drift. Thia potential will be mitlgsted using fish mix and other msterlals that are expected to be stable and not prone to erosion, littoral drift, or offshore tranaport. Sediment transport will be monitored before and after the project construction. g. About what percent of the site will be cOvered wHh Impervious surfaces after project construction (for exampie, asphait or buildings)? This project will not create any impervious surfaces. h. Proposed measures to reduce or controi erOSion, or other Impacts to the earth, If any: Sediment, erosion, and pollution prevention control measures will be Implemented to minimize the potential for erosion. Beat Management Practices (BMPs) that will be Implemented to control and reduce erosion Include colr logs anchored along the shoreline to help stabilize new sofls and mulch while plantings become established. Uve stakes will be planted along the shoreline to help stabilize the shoreline. Temporery strew wattles will be placed upland to contain any potential erosion from construction of the new boardwalk and naw plantinga. A floating turbidity control curtain will be placed In offshore watars surrounding the work area to contain any suspended sedlmenta resuHing from placing new shoreline matarlals and constructing Engineered Log Jams (EU). Previoua shoreline atudies of Bird Island reported minimal change between 2006 and 2010 at . the shoreline bank and waterline, !Suggesting that shoreline erosion Is a relatively slow procesa. These studies were compared wHh bathymstry received In June 2015, and confirmed that very . little nearshore erosion has occurred over the decade; Beyond the Immedlata shoreline, Bird Island Is surrounded by a shallow submerged area which extends to the north and west from the Island. Bird Island Is also exposed to wind genersted wave action and wave action from boating activity In Lake Washington. A coastal engineering analysis was performed In 2015 to dstarmlne the magnHude of these forces, as wall as the possibility of wind and wave forces contributing to sHe erosion. this analysis concluded that the forces generated by the wave conditions should not be sufficient to cause algnlflcant sediment transport of submerged particles. this Indlcatas that the sHe Is suRable for shoreline restoration which Includes the placement of new material. Drift cells In Lake Washington have not been mspped, 80 H Is unknown If sediment from areas outside the project IImHswlll deposH wHhln the area over time. Specific elementa of the design have been Included to help stabilize the new shoreline habitat as well as provide habitat features. Two EU will be placed perpendicular along the shoreline to help protect the beach from wave action and sediment transport. Placement depth Is not deSigned to exceed 18.7' elevation, In order to prevent or minimize beaa or other predation on Juvenile protected fish. Drift logs will be anchored along specific sections of the shoreline for habHat benefits as well as helping to reduce erosion. Sheats #8 and #7 of the design drawings dated December 2015 show restoration dealgn elementa and placement locations of these EU. 2. Air a.

Ust threatened and endangered species known to be on or near the site. No threatened or endangered plant apecles are known to occur at this site. The WDNR Naturel Heritage Information System was queried to determine whether the Bird Island occurs In a location reported to contain high quality natural heritage wetland or naturel heritage featurea commonly associated with wetlands. According to WDNR data dated October 14, 2015, there are no recorda of rare plante or high quality native ecosystems occurring on or near the subject properties. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, If any: The objective of this proposal Is to plant four different zones of native vegetation. Zone 1 Is . approximately 3,452 square feat of lake fringe emergent. Thla zone la located below the Ordinary High Water Mark and Includes bulruah and &edge apecIes. Zone 21a approximately 1,161 square feat of slough emergent wetland. this zone la a slough area that runa acrose the center of the laland and Is wat In the winter and dry In the aummer. Thla area will be planted with ruahes and &edges. Zone 3 Is approximately 4,164 square feat and runs along the lalanda shoreline. this area will be planted with willow live atakes and dogwood. Zone 41s approximately 3,216 square feat of upland shrub and trees. this area located on the Inside of the Island will be a mix of native ahrubs and conifers. A 9,747 square foot Category IIlaka fringe watland la located on Bird Island. The City of Renton MuniCipal Codes regulatea that this type of watland haa a 150 foot buffer. Due to the siZe of the Island the 150 foot buffer encompaasea the entire Island. The riparian wetland on the north and west of the Island has eroded and much of the slough watland la lacking vegetation or Is Invaded with noxious weeds. There will be no permanent adverse Impacts to the shoreline and wetland vegetation. Permanent Impacte to the upland wetland buffer will occur with the additional construction of the 200 feet of boardwalk trail. The location for the new trail currently lacks vegetation. The project will remove 30 feat of exlatlng boardwalk crastlng 180 square feat of new vegetated habitat.

The habitat is currently degraded due to shoreline erosion, uncontrolled public access, concrete and metal shoreline debris, and invasive species. Weeds of concern include the yellow·flag iris (Iris pseudacorus), reed canarygrass (Phalaris aurndianacea), Himalayan blackberry (Rubus armeniacus), all Class C Noxious Weed in King County, and tansy ragwort (Senecio jacobaea) a Class B Noxious Weed in King County. There are 25+ deciduous trees growing on the island including Pacific willow (Salix lucida), Oregon ash (Fraxinus latifolia), red alder (Alnus rubra), weeping willow (Salix babylonica) and two cherry trees. A variety of emergent, shrubs, and grasses are growing on the property including hedge nettle (Stachys sp.), tall mannagrass (Glyceria elata), bentgrass (Agrostis sp.) , snowberry (Symphoricarpos albus), and Nootka rose (rosa nutkana). , 'Sm.

This park is 57 acres of land and water that offers a boat launch, swimming area, trails, food concessions, fishing pier, volleyball, tennis, playground, horseshoe pit, and picnic shelters. Bird Island is an artificial island, formed of rubble, fill, and debris. Its shape and location have changed in the past 60 years as is evident between the aerial photos from 1937 and 2010. The shoreline of the island is currently littered with concrete and metal debris. Parts of the shoreline have eroded over the years and invasive vegetation such as Himalayan blackberry, reed canarygrass, and yellow·flag iris is growing on the island, as well as a number of native species. A bridge and boardwalk connects the island to the park providing park user's access to the island. Currently the intent is that park users stay on the existing boardwalk rather than wander through the vegetation and along the shoreline.

The scope of work includes: , • Enhance shallow water habitat by placing approximately 2,700 cubic yards (cy) of substrate enhancement (fish mix, consisting of clean sand and fine gravel, (1,950 cy below OHWL, 750 cy above OHWL), along the shoreline to increase and enhance juvenile Chinook habitat. • Construct two engineered log jams (ELJs) • Place 12 anchored logs • Remove approximately 321 cy of debris from shoreline (weight of 250 tons of soil, sand/gravel, and bouldet-sized particles, 525 tons of steel/concrete, representing a 60-to-40% mix of dirt and steel/concrete, respectively) of debris from shoreline • Removing nonnative or invasive plants to the extent possible • Plant native, emergent, and/or riparian vegetation along the shoreline and upland to control public access and enhance habitat for other species • Protect existing native vegetation • Enhance 8,777 square feet of existing wetlands • Improve existing public access trail with new railings and increase the boardwalk trail system by 200 lineal feet with a new and improved loop • Cut fill, set foundations, stringers, deck, and rail comprising 200 feet (1,200 square feet) of new boardwalk • Remove 30 feet (180 square feet) of existing boardwalk • Place new educational signage along boardwalk • Prevent shoreline or sediment the extent 6b_ Describe the purpose of the project and why you want or ,need to perform it. ~ The primary project goal is to improve juvenile Chinook salmon rearing and migration with a secondary goal of improving lake and nearshore habitat for reptiles/amphibians, and other wildlife in this portion of southeastern Lake Washington as well as enhance public access for park users. This project is listed as number C266A on the three year work plan under the Water Resource Inventory Area (WRIA) 8 Chinook Salmon Conservation Plan. The project is a Tier 1 priority under the WRIA 8 plan due to the project's location in the migratory and rearing corridor for Chinook salmon. The project will accomplish priority actions under the Conservation Plan by increaSing overhanging vegetation and removing debris along the shoreline and enhanCing important shallow water habitats closest to the mouth of the Cedar River, where such habitat is most heavily used by juvenile Chinook salmon. Bird Island offers a unique opportunity to provide and enhance important shoreline habitat for rearing and migrating juvenile Chinook salmon and other animals that is lacking along the shores of Lake Washington. The National Marine Fisheries Service listed the Puget Sound Chinook salmon as Threatened in March 1999 under the Endangered Species Act. Puget Sound coho salmon are considered a species of concern, and Puget Sound steelhead were listed Threatened under the ESA in May 2007. Docks, other overwater structures, and armored shorelines on Lake Washington are not the preferred shoreline habitat for juvenile salmonids and other species. Studies show that juvenile Chinook salmon prefer shallow water sandy beaches free of overwater structure, with overhanging and/or riparian vegetation. These types of habitats protect these fish from predation and allows them to rear in shallow waters of Lake Washington, and to more successfully migrate between January and May through Lake Washington, Lake Union, exiting through the Ballard Locks, into Puget Sound, and beyond. The proposed fish mix materials and grading along the shoreline of Bird Island enhances this habitat, and grading a placement of topsoil and mulch on the island will help to remove invasive seed stock and improve the quality of soils for new native plantings. The site's proximity to the Cedar River made it an ideal location for an enhancement project due to studies showing that the juveniles tend to rear in preferred habitat near the mouth of the river. Moreover, the project will help provide connectivity for juvenile Chinook migratory habitat between the mouth of the Cedar River and the recently completed South Lake Washington Shoreline Restoration Project. The project proposal is compatible with the City of Renton Parks maintenance, public awareness, and shoreline enhancement vision for Gene Coulon Memo'rial Beach Park.

' , o Not applicable U:!§!Ill One wetland, deSignated Wetland A, has been delineated on Bird Island, as specified in Attachments D and E of the Critical Areas Study (attached) performed for the site. No permanent adverse impacts to the wetlands are anticipated due to the project. Temporary impacts to the wetland will occur during the project construction. An additional 200 feet of boardwalk trail will cause permanent impacts to the wetlands upland buffer due to the wetland buffer encompassing the entire upland area of the island. The regulated buffer width for Wetland A is 150 feet. There is no vegetation growing in the wetland buffer area that the proposed 200 feet (1,020 square feet) of new boardwalk will be constructed on. Every effort will be made to minimize impacts to Wetland A during project construction, but due to the nature of the habitat restoration (grading the shoreline and substrate enhancement) some temporary impacts are unavoidable. Temporary impacts may include loss of some of the wetland vegetation located in the areas where fish mix (i.e. sand and fine gravel) will be placed as well as potential temporary water quality impacts. Best Management Practices will be in place to control and reduce temporary erosion and sediment to minimize disturbance to wetlands. Coir logs and anchored logs will be placed along the shoreline to stabilize the shoreline. Live stakes will be planted along the shoreline, which will also help stabilize the shoreline materials. During construction temporary straw wattles will be placed upland to contain any potential erosion from the construction of the new boardwalk. Native wetland vegetation will be protected as is feasible to construct the project. The existing wetland and an additional 3,216 square feet of shoreline will beJ)lanted with a variety of emergent plants JARPA Revision 2012.2 Page 7 of 16 and shrubs. In addition, new will be monitored for five years ,1""IIIY· Approximately 30 feet (180 square feet) of existing boardwalk will be removed. This area will be enhanced with wetland plantings. These temporary impacts to the wetland and permanent impacts to the wetland buffer will be mitigated through the end results of the enhancement project providing a '1unctionallift" of the habitat on the island.

[bg!Q] The critica, area study is intended to enhance approximately 25,531 square feet of shoreline and aquatic habitat and to enhance the 8,777 square feet of Category II wetland found on Bird Island (Wetland A). As discussed in the critical area study, the buffer for Wetland A encompasses the entire upland area of Bird Island. The existing area of Wetland A is 9,750 square feet (0.22 acres) and once the project is complete, the newly vegetated area of Wetland A will extend to approximately 13,400 square feet. This will be accomplished by restoring the existing wetland by revegetating the shoreline area with shrub and emergent vegetation. Different methods to protect the vegetation during its early growth will be installed and a 5 year vegetation maintenance and monitoring program will occur following the construction. Thirty feet of existing boardwalk located within the wetland and wetland buffer will be removed to create new or enhance existing habitat. This mitigation goal is compatible with the primary project goal of improving juvenile Chinook salmon rearing and migration habitat, with the secondary goal of improving lake and nearshore habitat for reptiles/amphibians, and other wildlife in this portion of southeastern Lake Washington as well as enhance public access for park users. This project is listed as project number C266A on the three year work plan under the Water Resource Inventory Area (WRIA) 8 Chinook Salmon Conservation Plan.

D Not applicable As noted in Section 6 above, the primary project goal is to improve juvenile Chinook salmon rearing and migration habitat in Lake Washington, with a secondary goal of improving lake and nearshore habitat for reptiles/amphibians and other wildlife as well as enhance public access for park users. No permanent adverse impacts to Lake Washington are anticipated due to the project. Temporary impacts during construction of the project will be minimized with the use of Best Management Practices (BMPs). BMPs will be in place to control and minimize turbidity. During the in-water work activities a floating turbidity control curtain will be placed around the construction work area in Lake Washingtori to contain suspended sediments and prevent any turbidity "plume" from being transported beyond the project borders. Coir logs and anchored logs will be placed along the shoreline to stabilize the shoreline. Live stakes will be planted along the shoreline, which will also help further stabilize the shoreline. During construction temporary straw wattles will be placed upland to contain any potential erosion from the construction of the new boardwalk and new plantings. Turbidity produced by the project will be kept to a minimum and is expected to cause only a short term impact to the shoreline. In-water work will be limited to Department of Fish and Wildlife regulated work windows to minimize impacts to fisheries. The contractor will be required to have a Spill Prevention Control and Countermeasures plan in place during the project construction. A coastal engineering analysis was performed to determine the possibility of wind and wave forces contributing to site erosion of the project site. This analysis concluded that the forces generated by wave conditions would not be expected to cause significant sediment transport of submerged particles. Specific elements of the design have been included to help stabilize the new shoreline habitat as well as provide habitat f.eatures. Two Engineered Log Jams will be placed perpendicular along the shoreline to help protect the beach from wave action and sedimenttransport. Placement depth is not designed to exceed 18.7' elevation, in order to prevent or minimize bass or other predation on juvenile prey, which are protected fish. Drift logs will be anchored along specific sections of the shoreline for habitat benefits as well as helping to reduce erosion. DNR will. complete a sediment transport study of the project site to monitor any potential movement of the newly placed fine gravel. The final outcome of the project will provide a benefit to the aquatic environment through placement of fine gravel, large woody debris, and engineered log jams. 8b.

The applicant for the BISEP is Monica Shoemaker, of the Washington Department of Natural Resources (WDNR). Figure 1 is a map showing the site location. The City of Renton Development Services Division requested a CAS based on a pre-application meeting with City of Renton staff on August 27, 2015. For the purposes of this CAS, the study area consists of Bird Island and adjacent parcels #33445000775, #0523059076, and #05~3059075. Hart Crowser biologist, Diane Hennessey, a professional wetland scientist, and Jim Shannon, a certified fisheries professional, performed site visits on May 12, June 15, and July 9,2015, and reviewed literature to determine· whether critical areas are present on and within 200 feet of the study area. This CAS was prepared in accordance with. City of Renton criteria, as defined in the Renton Municipal Code (RMC) 4-3-090 Shoreline Master Program Regulations (City of Renton 2015). The following sections of this CAS describe the methods used in the field investigation and our findings. VICINITY MAP Figure 1 -Vicinity map and project site aerial photo --FINAL iINriCiiOwsEii AERIAL PHOTO 12132·33 December 2, 2015 --------------------------------------------------------- • • 2 I Critical Areas Study, Bird Island Shoreline Enhancement Enhancement 2.0 SITE DESCRIPTION Bird Island is a manufactured island along the southern shoreline of Lake Washington, near the mouth of the Cedar River and adjacent to Gene Coulon Memorial Beach Park. The property is surrounded by the harbor limits of Lake Washington on all sides (WDNR property) except the south, where it borders a small private property (SECO) on the island's southwest corner. The exact date of its original construction is unknown. A timber b~idge provides access to the island from the park and to the timber boardwalk that provides access to approximately 50 percent of the island's perimeter (Appendix A). Plant communities on the island include native and non-native species that are used by. numerous animal'species, but this habitat is currently disturbed by frequent human access off the designated trail. The shoreline around the island is highly eroded, particularly on the west, north, and east sides of the island. Concrete and steel debris is visibl.e along the shoreline 'and is generally more concentrated in areas with concentrated erosion and scarps. Beyond the immediate shoreline, Bird Island is . surrounded by a shallow submerged area that extends to the north and west from the island. 2.1 Topography The elevation of Bird Island ranges from 30 feet at its high point to the ordinary high water mark (OHWM) of 21.7 feet in the summer and 20 feet in the winter. Banks are steep on the north and west side of the island b.ecause of shoreline erosion. There is a low depression, the slough, that bisects the island in an east-west orientation. This low depression/slough is inundated during the summer, when water levels in the lake are higher. 2.2 Soils Bird Island is an artificial island comprised mostly of unconsolidated fill that consists of sandy and silty soils in the upland portion of the island, and gravels, cobble, and larger rocks along the shoreline. The Natural Resources Conservation Service's (NRCS) Web Soil Survey was queried to identify the mapped soils within the study area. The soils within the study area are mapped as urban land (NRCS 2015). Urban land is listed as not hydric on the NRCS Hydric Soils List for Washington (NRCS 2015). 2.3 Hydrology The study area is in the Cedar River-Lake Washington watershed, Water Resource Inventory Area (WRIA) 8. Hydrologic characteristics in the study area are influenced by direct precipitation and Lake Washington, which borders the study area. The topography on site is moderately sloped on all sides and any surface stormwater that is collected within the study area flows toward Lake Washington. The OHWM of Lake Washington varies throughout the year. In the summer, the OHWM is elevation 21.7 feet, and in the winter it is 20 feet. 2.4 Sensitive Wildlife and Plant Species The Washington Department of Fish and Wildlife's (WDFW's) Priority Habitats and Species (PHS) database on-line mapper was queried to determine whether state or federally listed fish or wildlife 12132-33 December 2, 2015 FINAL • •• Critical Areas Study, Bird Island Shoreline Enhancement Enhancement I 3 species occur on or near the assessment area (WDFW 2015). According to the PHS database, no terrestrial priority species or habitats occur on the site or in the vicinity. Several species of anadromous and resident fish species occur in and around Bird Island, and their use of Lake Washington waters is . assumed. These species include Chinook salmon, coho salmon (Oncorhynchus kisutchj, sockeye salmon (0. nerka), kokanee, winter steelhead trout (0. mykiss), and resident coastal cutthroat trout (0. clarki). The WDNR Natural Heritage Information System was queried to determine whether the Bird Island occurs in a location reported to contain high quality natural heritage wetland or natural heritage features commonly associated with wetlands. According to WDNR data dated October 14, 2015, there are no records of rare plants or high quality native ecosystems occurring on or near the subject properties. 3.0 PRO.JECT DESCRIPTION The primary goal of the BISEP is to improve juvenile Chinook salmon rearing and migration habitat, with secondary goals of improving lake, wetland, and nearshore habitat for waterfowl, reptiles/aniphibians, and other wildlife, and restoring the eroded shoreline and degraded wetlands. This project is listed as project number C266A on the 3-year work plan under the WRIA 8 Chinook Salmon Conservation Plan (WRIA 8 Steering Committee). This project is a Tier 1 priority under the WRIA 8 plan because of the project's location in a migratory and rearing corridor for Chinook salmon. This project will accomplish priority actions under the conservation plan by increasing overhanging vegetation and removing debris along the shoreline and enhancing important shallow water habitats closest to the mouth of the Cedar River, where such habitat is most heavily used by juvenile Chinook salmon (Tabor and Piaskowski 2002; Tabor et al. 2004; Tabor et al. 2006; Tabor 2011 et al.; Tabor 2015). WDNR in partn·ership with the City of Renton Community Services Department is proposing to . enhance approximately 525 feet of shoreline habitat and approximately 0.4 acres of upland habitat. The project elements include: • Enhance shallow water habitat by placing appropriately sized substrate along the shoreline to increase and enhance juvenile Chinook habitat. • Construct two engineered log jams (EUs). • Place 12 anchored logs along the shoreline. • Remove approximately 321 cubic yards of debris from shoreline (525 tons of steel/concrete and 250 tons of dirt, a 60 to 40 percent mix). • Remove nonnative or invasive plants to the extent possible. • Plant native, emergent, and/or riparian vegetation along the shoreline and upland to control public access and enhance habitat for other species. • Protect existing native vegetation. • Improve existing public access trail with new railings and increase the boardwalk trail system by 170 linear feet (1,020 square feet [sf]) with a new and improved loop system. • Place new educational signage along boardwalk discouraging shoreline access. • Prevent shoreline erosion or sediment transport to the extent possible. --FINAL HNiit:RoiiiiiR. 12132-33 December 2, 2015 ------------------------------------------------ • • 4 I Critical Areas Study, Bird Island Shoreline Enhancement Enhancement In addition to the proposed habitat enhancement, the existing trail will also be extended. A site plan of existing and proposed conditions is provided in Appendix B. 4.0 CRITICAL AREAS ON SITE Bird Island is in Lake Washington, which is designated as a Type S waterbody under RMC Section 4-3- 050 (City of Renton 2015). Regulations for Type S waterbodies are described in RMC 4-3-090, Shoreline Master Program Regulations. Under RMC 4-3-090, Lake Washington is designated a Shoreline of Statewide Significance in the shoreline high-intensity overlay district. The jurisdictional area of shorelines of statewide significance is 200 feet from the OHWM. There are two OHWMs in Lake Washington because the lake level is regulated by the locks in Seattle. The OHWM in summer is 21.7 feet and the ordinary low water mark (OLWM, in winter) is 20 feet. Hart Crowser biologists identified one wetland on Bird Island, Wetland A, during our site visit on May 12, 2015. Our methods followed the RMC procedures and are described in the following section. 4.1 Wetlands In this section we describe the methods and results of our wetland delineation of Bird Island. 4.1.1 Methods 4.1.1.1 Delineation This wetland was delineated in accordance with the Regional Supplement to the US Army Corps of Engineers' Wetlands Delineation Manual: Western Mountains, Valleys, and Coast Region (Environmental Laboratory 2010), which is consistent with the 1987 Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). These methods use a three-parameter approach for identifying and delineating wetlands, which is based on the presence of field indicators for hydrophytic vegetation, hydric soils, and hydrology. The specific methods using these three parameters are described in Appendix C. To identify potential wetlands, Hart Crowser wetland biologists evaluated field conditions by walking through the entire study area on May 12, 2015. For each location that appeared to have potential wetland characteristics, data on dominant plant species, soil conditions in data plots, and evidence of hydrologic conditions were recorded on routine wetland data forms. Adjacent upland locations were also analyzed. On the basis of the collected data, a determination of wetland' or upland was made for each location examined. Wetland flags were hung along the wetland boundaries. After the confirmation of all three wetland parameters, the boundaries of the wetland were flagged by Hart Crowser and then surveyed by a licensed surveyor. The wetland boundaries are illustrated in Appendix B. The methods used to classify, rate, and assess the functions of the delineated wetlands are described below. 12132·33 December 2, 2015 FINAL • • Critical Areas Study, Bird Island Shoreline Enhancement Enhancement I 5 4.1.1.2 Wetland Classification and Rating The wetlands in the study area were classified according to the US Fish and Wildlife Service classification system, which is based on an evaluation of attributes such as vegetation class, hydrologic regime, salinity, and substrate (Cowardin et al. 1979). The wetlands were also classified according to the hydrogeomorphic system, which is based on an evaluation of attributes such as the position ofthe wetland within the surrounding landscape, the source and location of water just before it enters the wetland, and the pattern of water movement in the wetland (Brinson 1993). 4.1.1.3 Wetland and Stream Ratings and Buffers Wetland ratings were evaluated using the Washington State Wetland Rating System for Western Washington (Ecology 2014) as specified in the RMC. The Washington State Department of Ecology (Ecology) rating system has four wetland categories, with Category 1 wetlands exhibiting outstanding features and Category 4 wetlands exhibiting mini'mal attributes (2014). The RMC identifies buffer widths and permitted uses in the wetland and its buffer based on the wetland rating categories, The ratings are also used to identify the mitigation ratios needed to compensate for potential impacts on wetlands, 4.1.2 Results One wetland, Wetland A, was delineated within the study area, Wetland A is associated with Lake Washington. Upland areas outside Wetland A consist of a boardwalk, mowed lawns, shrub habitat, or mixed coniferous and deciduous trees. Table 1 summarizes information on the size, vegetation, and soils of Wetland A. The table also provides the Cowardin (1979) classification, hydrogeomorphic classification, and Ecology category rating and buffer requirements . .. .. ~ FINAL 12132·33 December 2, 2015 I I • • 6 I Critical Areas Study, Bird Island Shoreline Enhancement Enhancement Table 1 -Wetland A Classification, Rating, and Buffer Requirements 9,747 square feet, or 0.22 acie PSS/PEM Lake fringe data fonn(s) Appendix E, DPWETA1 Appendix E, DPWETA2 UPL Wetland A consists of shrub and emergent communities that are located along the shoreline of Lake Washington and within a 8Wale that bisects the island. The island also contains occasional mature trees. The scrub-shrub community is dominated by Pacific willow (Salix lucida) and clustered rose (Rosa pisocarpa). Himalayan blackberry is present in some locations and encroaches into the we~and. The shrub vegetation is dense and consequen~y there is little groundcover because of the shade of the shrubs. The emergent community is primarily in the swale and contains tall mannagrass (Glycaria a/ata), reed canarygrass (Phalaris arondinancaa), bentgrass (Agrostis sp.), hedge nettle (Stachys sp.), and a few lady fern (Athyrium falix-famina). Yellow flag iris (iris psaudacoros) is a non-native and a Class C noxious weed that has taken over a portion of the swale. Removal of this noxious weed is desirable. Trees observed within and adjacent to the wetland include mature Pacific willow, Oregon ash (Fraxinus latifolia), and red alder (Alnus robra). Pacific willow trees and shrubs and a few red alder are rooted within the southern and westem shorelines and overhang the banks .. A large mature weeping willow (Salix babylonica), a non-native species, is present in the center of the island. Soils were examined to a 16-inch depth and exhibited hydric characteristics. At DPWETA1, soils were very dark grayish-brown (1 OYR 212) silty clay loam to a depth of 6 inches, over a 1O-inch layer of dark gray (10YR 212) silty clay loam with redoximorphic concentrations (10YR 3/3, 5 percent, in the matrix). This profile meets the criteria for the hydric soil indicator: redox dark surface (F6). Soils were saturated to the surface and contained water at 10 inches below the surface. The main hydrologic input to this wetland is from Lake Washington, with secondary inputs from precipitation and runoff from the center of the island and boardwalk. Lake Washington water levels are regulated and vary in elevation by 1.7 feet between the summer (21.7 feet) and winter was used to rate the wetland. Renton's recommended buffer rating for this wetland is Category we~and is 150 feet. condition Buffers surrounding the we~and consist of shrub habitat, disturbed grassland, and the occasional tree. The primary vegetation in the upland area is snowberry, Nootka rose, and disturbed and mowed 12132-33 FIN A L Oecember 2, 2015 • • Critical Areas Study, Bird Island Shoreline Enhancement Enhancement I 7 4.1.3 Wetland Buffers Critical areas under shoreline jurisdiction in the Cityof Renton are regulated by RMC Title 4-3-090 (Shoreline Master Program). The code stipulates using the Ecology (2014) wetland rating system for Western Washington to rate the wetland. Wetland A was determined to be a Category II wetland using the Ecology rating form (see Appendix D). The wetland buffer width is based on a combination of the wetland category and the habitat score from Ecology's rating form (RMC 4-3-090.D). Wetland A received 6 habitat points (equivalent to 20 to 28 points under the RMC) and requires a standard buffer width of 150 feet in shoreline jurisdiction areas. Therefore, the buffer for Wetland A encompasses the entire upland area of Bird Island. 5.0 HABITAT AND CUMULATIVE IMPACTS ASSESSMENT Bird Island aquatic and upland habitat is degraded. The riparian wetland area on the north and west side of the island has been eroded so that it is narrow or non-existent (see' Appendix A for photographs ofthe degraded shoreline). Approximately 70 percent of the island contains native shrubs and emergent vegetation, and the remaining vegetation consists of non-native species. There are currently shoreline scarps caused by wave action and public use, particularly to the western and southeastern portions of the shoreline. Aquatic habitat is degraded with steel and concrete debris below the OHWL, mostly along the northern and western portions of the island's shoreline. The nearshore habitat is degraded in these areas, but is at depths that are optimal for juvenile Chinook salmon rearing habitat. The nearshore aquatic habitat along the eastern and southern portions of the island are in better condition than the other areas (e.g., there is no erOSion, and there is overhanging riparian vegetation). The eastern and southern portions of the nearshore contain valuable shallow water areas with riparian cover, gravel substrates, and the occasional pieces of large woody debris (LWD) that are important rearing habitat for juvenile Chinook salmon. This project is designed to enhance habitat for fish and wildlife and improve the conditions of Wetland A, Wetland A buffer, and Lake Washington shoreline habitat. This enhancement project is expected to result in net overall beneficial effects to fish and wildlife and involve using best available science in the design (Tabor 2011 et al.; Tabor 2015). However, there will be permanent beneficial modifications (impacts) to habitat from construction of the enhancement project. The project elements include debris removal, grade restoration, substrate enhancement below the OHWM, shoreline enhancement with LWD, and wetland and upland vegetation enhancement. Table 2 details the location, materials, area, and cubic yards of each enhancement action.

In total 8,777 sf of Wetland A will be enhanced. Of this total 2,997 sf of Wetland A will be enhanced with fish mix and native vegetation. The remainder of Wetland A (5,780 sf) will be enhanced with native vegetation only. Permanent impacts to the Wetland A buffer include an additional 1,020 sf (add 1,200 sf and remove 180 sf) of trail within the Wetland A buffer. However, 3,216 sf of Wetland A buffer will be enhanced with native vegetation to offset this trail extension impact. The proposed trail extension will not significantly affect the function of Wetland A or its buffer. Below the OHWM 24,270 sf of substrate will be enhanced with fish mix. Temporary impacts to habitat include potential water quality impacts from project construction (Le., stormwater runoff). However, potential construction impacts would be temporary and minimized by construction best management practices (BMPs). Measures to avoid, minimize, and mitigate for project impacts include: • All in-water work will occur within the agency-approved work window for Lake Washington. • Construction will be managed to prevent incidental spills, debris, and foreign materials from entering into Lake Washington. • Temporary erosion and sediment control best management practices will be implemented. • Oil spill response equipment will be on site and a spill response plan will be in hand and deployed as necessary by the contractor. 12132·33 December 2, 2015 FINAL • • .

Ecological benefits of BISEP include debris removal and shoreline, substrate, wetland and buffer enhancement. Temporary impacts to Wetland A and permanent impacts to the Wetland A buffer will be mitigated through this enhancement project. Degraded wetlands will berestored along the west and through wetland and buffer vegetation enhancements and restoration of eroded shoreline.

These methods use a three-parameter approach for identifying and delineating wetlands : the presence of field indicators for hydrophytic vegetation , hydric soils , and hydrology. Hydrophytlc Vegetation Hydrophytic vegetation is characterized by the ability to grow, effectively compete, reproduce, and persist in anaerobic soil conditions resulting from periodic or long-term saturation (Environmental Laboratory 1987). Vegetation must meet at least one of the four indicators (described below) that are used to determine the presence of hydrophytic vegetation in wetlands . Problematic and atypical situations for hydrophytic vegetation are also described in the Corps manual and supplement (Environmental Laboratory 1987 and 2010). Plant Species Identification Plant species were identified using Flora of the Pacific Northwest (Hitchcock and Cronquist 1987) and A Field Guide to the Common Wetland Plants of Western Washington and Northwestern Oregon (Cooke 1997). The indicator status of each plant species is based on the North American Digital Flora : National Wetland Plant List, version 2.4 .0 (Lichvar and Kartesz 2009) for the Western Mountains, Valleys , and Coast Region . Dominant Species Determination Dominant species are those that contribute more than other species to the character of a plant community. To determine dominance, a vegetation sampling area is determined by the field biologist to accurately characterize the plant community that occurs in the area to be evaluated . These are commonly circular sampling area s, centered on the location of the test plot (where soil and hydrologic data is also collected). The radius of the circle is determined in the field, based on site conditions . In large wetlands, a typical sampling radius would be 2 to 5 meters for tree and sapling/shrub species , and 1 meter for herbaceous species. In a small or narrow wetland (or upland), the radius might be reduced to accurately sample wetland (upland) areas , thereby avoid i ng an overlap into an adjacent community having different vegetation, soils, or hydrologic conditions (Environmental Laboratory 2010). Within the vegetation sampling area , a complete list of plant spec ies that occur in the sampling area is compiled and the species divided into four strata : tree, shrub (including saplings; see criteria below), FINAL 12132-33 De ce mb e r 2. 2015 • • C·2 I Critical Aras Study, Bird Island Shoreline Enhancement Enhancement herb, and woody vines '. A plant is included in the tree stratum if it is a woody plant 3 inches diameter at breast height (dbh) or greater; in the shrub stratum if it is a woody plant less than 3 inches dbh (including tree saplings under 3 inches dbh); In the herb stratum if it is an herbaceous (non-woody) plant; and in the woody vine stratum if it is a woody vine of any height (Environmental laboratory 2010). To be included in the sampling, 50 percent or more ofthe plant base must be within the radius of the sampling area. For trees specifically, more than 50 percent of the trunk (diameter) must be within the sampling radius to be included. A rapid test, dominance test (e.g ., the 50/20 rule), or prevalence index are commonly used to determine which species are considered dominant and to assess whether the criteria for hydrophytic vegetation are met at each test plot (Environmental laboratory 2010). Additional hydrophytic vegetation indicators are discussed in the following section. To conduct a rapid test (Indicator 1 on the wetland determination data form), the dominant species are evaluated visually and if all are FACW or OBl, the vegetation data passes the rapid test. To conduct a dominance test (Indicator 2 on the wetland determination data form), the absolute areal coverage of the plant species within a stratum are totaled, starting with the most abundant species and including other species in descending order of coverage, until the cumulative coverage exceeds 50 percent of the total coverage for the stratum. The plant species that constitut"e this first 50 percent of areal coverage are considered the dominant species In the stratum. In addition, any other any single p lant species that constitutes at least 20 percent of the total percent cover in the stratum is also considered a dominant species (Environmental Laboratory 2010). The indicator status category for each plant (shown in Table C-1) is also listed on the wetland determination form . If more than 50 percent of the dominant species across all strata are rated OBl, FACW, or FAC, the hydrophytic vegetation dominance test (Indicator 2) is met. 1 CaAiotI .......... 1n ..... rn¥_In ..

The prevalence index (Indicator 3 on the wetland determination data form) is a weighted-average wetland indicator status of all plant species in the sampling plot, where weighting is by abundance (Environmental Laboratory 2010). This method is used where indicators of hydric soil and wetland hydrology are present, but the vegetation initially fails the rapid and dominance tests (Indicators 1 and 2). To determine the prevalence index, the absolute cover of each species in each stratum is determined. All species (across all strata) are organized into wetland indicator status groups (i.e ., OBL, FACW, FAC, FACU, or UPL) and their cover values are summed within the groups . The formula for the prevalence index is applied. If the prevalence index (which ranges from 1.0 to 5 .0) equals 3.0 or less, this hydrophytic vegetation indicator is met. Additional Hydrophytic Vegetation Indicators The presence of morphological adaptations to wetland conditions in plants that lack a published hydrophytic vegetation indicator status or with an indicator status of FACU or drier is also a hydrophytic vegetation indicator (Indicator 4). Evidence of physiological, morphological, or reproductive adaptations indicating growth in hydrophytic conditions can include, but are not limited to, buttressed roots, adventitious roots, multi-stemmed trunks, or tussocks. To determine whether Indicator 4 is met, the morphological features must be observed on more than SO percent of the individuals of a FACU species (or species without a published indicator status) living in an area where hydric soil and wetland hydrology are present . On the wetland determination data form, the indicator status of the species with morphological adaptations would be changed to FAC (with supporting notes), and the dominance test (Indicator 2) and/or prevalence index (Indicator 3) would then be recalculated. Wetland non-vascular plants, referred to as bryophytes and consisting of mosses, liverworts, and hornworts, may also meet the hydric vegetation criteria, under Indicator 5 (Environmental Laboratory II HM'"'JOiOW'---SlR- FINAL 12132-3 3 December 2, 2015 I ------------------------------------------------~---------------------------------------------~ -~- • • C-4 I Critical Aras Study, Bird Island Shoreline Enhancement Enhancement 2010). These plants must be present in areas containing hydric soils and wetland hydrology. The percent cover of wetland specialist bryophytes is determined in lO-inch-by-lO-inch square plots placed at the base of hummocks, if present. The summed cover of wetland specialist bryophytes must be more than 50 percent of the total bryophyte cover in the vegetation sampling area. The "problematic hydrophytic vegetation" indicator section in the Corps regional supplement further explains how to interpret situations In which hydric soils and wetland hydrology are present but hydrophytic vegetation Indicators 1 through 5 are lacking (Environmental laboratory 2010). Procedures for looking at settings such as areas with active vegetation management (e .g., farms), areas dominated by aggressive invasive species, active floodplains, and low terraces are described, as well as explanations for specific situations, such as seasonal shifts in plant communities, extended drought conditions, and riparian areas. Hydric Soils A hydric soil is a soil that is saturated, flooded, or inundated long enough during the growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic vegetation (Environmental laboratory 1987 and 2010). The evaluation of existing soil maps (developed by NRCS and other sources) is used to understand hydric soil distribution and to identify the likely locations of hydric soils (by verifying their inclusion on the hydric soils list (NRCS 2015). Comparison of these mapped soils to conditions found on site help verify the presence of hydric soils . For on-site soils characterization, hydriC solis data were obtained generally by digging test pits at least 20 inches deep and 4 inches wide. Hydric soil conditions were evaluated using indicators outlined in Field Indicators of Hydric Soils in the United States (NRCS 2010), and adopted by the Regional Supplement to the US Army Corps of Engineers Wetlands Delineation Manual: Western Mountains, Valleys, and Coast Region (Environmental laboratory 2010 HydriC soil indicators applicable to the Western Mountains, Valleys , and Coast region include, but are not limited to, the presence of: organic soils (I.e ., histosols or histic epipedons); sulfidic material (I.e., hydrogen sulfide); depleted, gleyed, or reduced soil matrices; and/or the presence of iron or manganese concretions (Environmental laboratory 2010). Soil color characterization (i .e., hue, value, and chroma) is a critical tool in determining depleted, gleyed, and reduced soil conditions . Soil color was evaluated by comparing soil colors at test plots to standardized color samples in Munsell Soil Color Charts (Munsell Color 2000). Wetland Hydrology Wetland hydrology is indicated by site conditions that demonstrate the periodic inundation or saturation to the soil surface for a sufficient duration during the total growing season. A "sufficient duration " during the growing season is defined as 14 or more consecutive days of flooding, ponding, or presence of a water table at 12 inches or less from the soil surface (Environmental laboratory 2010). The growing season is the period of consecutive frost-free days, or the longest period during which the soil temperature stays above biological zero (410 F), when measured at 12 inches below the soil surface. 12132 -33 December 2, 2015 FINAL • • Critical Area Study, Bird Island Shoreline Enhancement Enhancement I c-! Two indicators of biological activity can be used to determine whether the growing season has begun and is ongoing (Environmental Laboratory 2010): • Occurrence of aboveground growth and development of at least two non-evergreen vascular plant species growing within the wetland . Examples of this growth include the emergence or elongation of leaves on woody plants and the emergence or opening of flowers. • Soil temperature, which can be measured once during a single site visit, should be at least 410 F or higher at a depth of 12 inches. For this assessment, onsite hydrologic indicators were examined at the test plots . Hydrologic indicators include the presence of surface water, standing water in the test pit at a depth of 12 inches or less, saturation in the root zone, watermarks, drift lines, sediment deposits, drainage patterns within wetlands, oxidized rhizospheres surrounding living roots, and water-stained leaves.
