TUKWILA SHORELINE MASTER PROGRAM - BACKGROUND The City of Tukwila adopted a Shoreline Master Program (SMP) on August 15, 2011 which was approved by the Washington State Department of Ecology on October 14, 2011 and became effective October 28, 2011. This project is subject to the Shoreline Master Program.

Shoreline Environment Designation The shoreline environment designation for the site is Urban Conservancy; the purpose of the Urban Conservancy Environment is to protect ecological functions where they exist in urban and developed settings, and restore ecological functions where they have been previously degraded, while allowing a variety of compatible uses. The shoreline buffer in the Urban Conservancy environment is 125 feet when the river bank is fortified with a levee (Figure 2). However, the Urban Conservancy buffer on this parcel is not a consistent 125' all along the river. Because the levee has been rebuilt, the buffer has been reduced, in places, to the landward toe of the levee per TMC 18.44.050 (D.2) (see attachment A for the existing location of the buffer). This buffer width is consistent with that established by the City's Sensitive Areas Ordinance for Type 2 streams that support salmonid use, which is based on Best Available Science. The final buffer widths adopted by the City and approved by Ecology for each shoreline environment attempted to balance shoreline ecological function needs, human life and property protection needs (including future levee repair/reconstruction), existing land use patterns, and state and federal agency policies.

Response: The proposed access improvements promotes vegetation conservation, is utilizing existing outfall slab and wing walls in lieu of adding additional foreign materials, and is providing a public access point for the City of Tukwila Public Works maintenance staff. The improved access will also encourage long-term maintenance of the outfall, helping to preserve the long-term benefits of the river. Goal 5.10 Water Quality, Surface Water and Flood Control Use Goal: Improved water quality and quantity control programs affecting the Green/Duwamish River that improve the river's water quality, provide habitat for fish and wildlife, protect public health and safety, and enhance public enjoyment of the river. • Policy 5.10.1: Design, locate, and manage shoreline development including streets, flood control projects, surface water drainage and sewer systems, clearing and grading activities, and landscaping in a manner which minimizes opportunities for pollutants to enter the river, provides erosion control and otherwise protects water quality. Response: The access to the existing outfall is being modified. The outfall itself is not being modified. The access improvements will not alter the opportunities for pollutants to enter the river, continues to provide erosion control and protects water quality. Goal 5.11 Public Health, Safety and Welfare Goal: Shoreline uses that do not endanger public health, safety and welfare, or the capacity of the river to provide long-term benefits and resources to the community. • Policy 5.11.1: Design, locate, and manage shoreline uses, such as capital improvement projects and private development, in a manner that does not endanger public health, safety and welfare, and enhances the capacity of the river to provide long-term flood protections, habitat and other benefits and resources to the community and the environment. Response: The access improvements will provide safe access to the City of Tukwila staff. The proposed access improvements will not disturb flood protection, habitats, nor the existing public access of the Green River Trail which runs parallel to the bank with the Green River at the project location. V. SHORELINE REGULATIONS TMC 18.44.130 (B.3) Administration states that a substantial development permit shall be granted only when the development proposed is consistent with the Shoreline Master Program (SMP). The relevant Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov Page 6 of 8 7/27/2016 \\dcdstore\DCD Common$\Users\Laura\Shoreline\L16-0039 Gilliam Creek Outfall\L16-0039 Gilliam Creek SSDP Staff Report.docx SMP goals and policies were discussed above. This site is located in an area that is inside of the Urban Conservancy Environment Buffer. Because of the reconstruction of the levee, the buffer has been reduced, in places, to the landward toe of the levee per TMC 18.44.050 (D.2). TMC 18.44.050 Permitted Uses The proposed access improvements to the existing Gilliam Creek Outfall are permitted per TMC 18.44.050 (B.1.p) for development within the Urban Conservancy Environment. A portion of the outfall is above ground. This will not be intensified or expanded as part of the access improvements. TMC 18.44.070 Development Standards Per TMC 18.44.070 the project is subject to the Development Standards. See TMC 18.44.070 Development Standards Checklist (Attachment B) for a more detailed analysis of the project in relation to applicable standards. Standards include: 1. (D.4) Surface Water and Water Quality: The project will increase the safety of access to the outfall with the proposed concrete stairway and landing with a steel frame, foundation, and ladder which provides access to the outfall. The 4' wide by 20' long cast -in -place concrete slab on grade will be constructed along the existing vegetated bank slope. The stair foundation will be composed of helical piles or mircopiles with a steel frame platform for the landing, Aside from removal of the grass vegetation on the bank for the concrete stairway there will be no additional change to the existing shoreline other than described above. Restoration is not required as part of the proposal as no landscaping is required on a federally certified levee as stated in TMC 18.44.080. 2. (J.1) Clearing, Grading, and Landfill: Land altering and fill will be required for the stairway access dimensions to meet ADA and all regulatory safety standards. Approximately 300 square feet of clearing grasses and vegetation is required for the on grade stair installation. The 2016 Small Drainage Project has identified and called out required erosion control and property restoration. The contractor will restore any vegetation and cap graded subgrade surface with rip rap or applicable ground cover to prevent bank erosion. The slope will be in stable condition before the project is considered substantially complete. TMC 18.44.080 Vegetation Protection and Landscaping Per TMC 18.44.080 the project is subject to the Vegetation Protection and Landscaping requirements. TMC 18.44.080 (C.1.a) states "on properties located behind publicly maintained levees, an applicant is not required to remove invasive vegetation or plant native vegetation in the buffer." As discussed above in IV.A Shoreline Environment Designation, the improvements to the Gilliam Creek Outfall are located behind a publicly maintained levee and thus removal of invasive vegetation and planting of native vegetation in the buffer is not required. TMC 18.44.100 Public Access to the Shoreline The proposed access improvements to the Gilliam Creek Outfall to do not trigger public access requirements as listed in TMC 18.44.100(1).

Design guidelines include: 1. (A.1) Relationship of Structure to Site: The access stairway is for maintenance access to ensure the outfall is in working condition. The City of Tukwila and other local jurisdictions caring for the Green River Trail will be able to continue their care, preservation, and maintenance of the Green River Trail and vicinity once the access has been constructed and completed. 2. (A.2) Building Design: There are no buildings associated with this proposal. 3. (A.3) Design of Public Access: Improvements to public access are not applicable to this project as discussed above. The access improvements to the Gilliam Creek Outfall will not affect access on the existing Green River Trail. Any temporary trail closures for construction will be clearly marked and detours will be put in place. VI. COMMENTS A Notice of Application was distributed to nearby residents, property owners, and applicable agencies on July 29th, 2016. The Notice of Application was also posted on the project site. No comments were received. VII. SEPA SEPA was triggered as part of this project. The City of Tukwila issued a DNS for the project on July 15, 2016 under file E16-0006. VIII. CONCLUSIONS 1. The proposal does not interfere with access to the shoreline and makes access to the existing Gilliam Creek Outfall safer for City employees for maintenance and repair. 2. The proposal does not interfere with the ability to maintain and repair the existing levee. 3. The project site is located behind a publically maintained levee and thus removal of invasive vegetation and planting of native vegetation in the buffer is not required. 4. The applicant shall obtain any necessary state or federal permits that pertain to this project. 5. The project is consistent with the economic development, shoreline design quality, access and recreational use, historical resource use and archaeological protection, and natural environment and habitat use goals and policies of the Shoreline Master Program. 6. The project is consistent with the requirements in TMC 18.44 Shoreline Overlay. 7. The applicant has demonstrated no net Toss of shoreline ecological functions for the proposed access improvements in the shoreline jurisdiction. IX.

A list of these goals and policies can be found in Chapter 6 of the Shoreline Master Program, see Attachment A to Ordinance 2344: http://www.tukwilawa.gov/dcd/shoreline.htnll . They are also available at the Tukwila Department of Community Development. Please discuss with a planner the goals and policies that should be addressed. The Gilliam Creek Outfall access improvement project complies with the applicable Shoreline Master Program goals and policies. Per Chapter 6 of the Shoreline Master Program this project follows the goals of the Urban Conservancy Environment. The proposed ouffall access promotes vegetation conservation, is utilizing existing outfall slab and wing walls in lieu or adding additional foreign material, and is providing a public access point for the City of Tukwila Maintenance. In addition, Goal 5.3 is reached with providing a safe access to the City of Tukwila. This safe and accessible stairway will encourage frequent care and routine maintenance of the Gilliam Creek Outfall only helping to preserve the long-term benefits of the river. This proposed access will also help to obtain Goal 5.11 and Policy 5.11.1. The proposed access to Gilliam Creek Outfall will provided needed safety upgrades for the City of Tukwila will not disturbing flood protection, habitats, and the existing public access of the Green River Trail which runs parallel with the bank of the Green River at this project location.

CPL Page 9 of 13 C:\Users\ryan-1\Desktop\Shoreline Sub Dev July 2016.docx NO NET LOSS CHECKLIST What is No Net Loss? The Washington State Shoreline Management Act (SMA) requires protection of the natural resources and ecological functions of the shoreline environment. Ecological functions are processes that characterize the river and its shoreline and form habitats for water- and land -based wildlife and vegetation. Ecological processes depend on the geology, soil type, topography, climate, and other physical characteristics in the region. In the Green/Duwamish River watershed, key ecological processes include: • river flows, tidal fluctuations and saltwater influences; • creation, transport and deposition of sediment (for example scouring of soils, and erosion and formation of mud -flats or beaches); • transport of nutrients (from decomposition of plants and other organic materials); • provision of woody debris from fallen limbs and trees along the banks or in the water (the trunks and branches help form pools for fish); and • water quality (such as vegetation that can help to filter out pollutants that are washed into the river from parking lots and vegetation that can help reduce temperatures in the river, important for fish, especially salmon). These physical and biological processes comprise the ecological functions of the shoreline. The state guidelines that implement the SMA, adopted in 2003, establish the standard of "no net loss" of shoreline ecological functions for land uses and development within the shoreline jurisdiction. The No Net Loss standard is designed to stop the introduction of new negative impacts to shoreline ecological functions resulting from new development. Tukwila's Shoreline Master Program (SMP) defines no net loss as a: "...standard intended to ensure that shoreline development or uses, whether permitted or exempt, are located and designed to avoid loss or degradation of shoreline ecological functions that are necessary to sustain shoreline natural resources." In other words, the existing conditions of the shoreline ecological functions should not deteriorate due to new permitted development or new land use. A loss of ecological function can occur when a physical condition such as vegetation along the shoreline is removed or when habitat is altered through the construction of a dock or pier or other structures over this habitat. In order to maintain shoreline ecological functions, negative impacts must be mitigated to restore an equivalent amount of ecological function. The approach to mitigation must follow the mitigation sequencing steps adopted in the SMP (see next page). It should be noted that the SMA and the City's SMP also require improvement of shoreline functions, and therefore, some re -vegetation of the shoreline will be required in proportion to the scale of the project, regardless of whether there is a net loss to ecological functions. CPL Page 10 of 13 C:\Users\ryan-1\Desktop\Shoreline Sub Dev July 2016.docx On a separate sheet of paper, please respond to the following questions to evaluate your project's impacts and assist in analyzing whether there will be a net loss to shoreline ecological functions requiring mitigation: 1. Describe the existing condition of the shoreline area and riverbank. For example, what plants and how much vegetation currently exist within the 200 foot shoreline jurisdiction; what is the condition of the shoreline (how steep are the banks, is there any erosion or slope failure, what are the soils like); is there "hard armoring" on the riverbank (for example, concrete or wooden bulkheads, metal sheet piling, rip -rap [rocks or concrete/asphalt blocks]), is there paving or are there any structures within the 200 ft. shoreline jurisdiction; are there any docks, piers, decks or other structures near or over the water; are there any above -ground or below ground utilities; etc.? The Gilliam Creek Outfall is directly connected to the Lower Duwamish/ Green River within the shoreline jurisdiction. The existing bank is composed of Levee fill soils with slopes ranging from 1:1 to 2:1. The bank is vegetated with grasses, blackberry, and deciduous trees. Isolated areas of rock protection exist at the existing outfall. The asphalt paved Green River Trail parallels the top of the Green River levee. The existing outfall pipe runs under the trail and discharges through an existing headwall and apron slab along the bank slope. The existing outfall is made up of a concrete apron slab, wing wall, headwall, and flap gate that provides flood protection to the Southcenter area during high river stages. The nearest location from the outfall to impervious driving pavement is approximately 200 linear ft. This impervious surface is the dead end cul-de-sac of 68`h Ave S (Christensen Rd.). 2. How will your project change the existing condition of the shoreline described above? The project will increase the safety of access to the outfall with proposed concrete stairway and landing with a steel frame, foundation, and ladder which provides river access to the outfall. The 4' wide x 20' long cast -in - place concrete slab on grade will be constructed along the existing vegetated bank slope. The stair foundation will be composed of helical piles or micropiles with a steel frame platform for the landing. The stairway, landing, and vertical ladder is required for maintenance crew access safety. Aside from the removal of grass vegetation on the bank for the concrete stairway there will be no additional change to the existing shoreline described above in terms of landscaping, paved areas, or utilities within the shoreline jurisdiction. 3. Please respond to the questions in the following chart - A No Net Loss analysis (prepared by a qualified biologist) must be prepared if the response to any of the questions in the chart below is "yes": WILL THE PROJECT: NO YES a. Alter/remove vegetation in the shoreline jurisdiction? x b. Alter the river bank (i.e. re -slope bank, add armoring etc.)? x c. Add fill in the shoreline jurisdiction? x d. Discharge new stormwater to the river? x e. Store or use hazardous materials in the shoreline jurisdiction? x f. Construct an in- or over -water structure? x CPL Page 11 of 13 C:\Users\ryan-l\Desktop\Shoreline Sub Dev July 2016.docx g. Increase impervious surface in the shoreline jurisdiction? 4. The way to achieve no net loss of ecological function is to mitigate the loss through one or a combination of the mitigation sequencing steps identified below. If preparing a No Net Loss analysis, please discuss how your project addresses the following mitigation sequencing steps (TMC 18.44.070 H.3.): a. Avoiding the impact altogether by not taking a certain action or parts of an action; b. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts; c. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment; d. Reducing or eliminating the impact over time by preservation and maintenance operations; e. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments; and f. Monitoring the impact and the compensation projects and taking appropriate corrective measures. A. An action needs to be taken to provide a safe access to the existing Gilliam Creek outfall. B. The stairway access dimensions have been designed to meet ADA and all regulatory safety standards, however a minimalistic foundation and frame is proposed for the access landing. The landing will be on an elevated slab allowing storm runoff under the landing and making its way into the water structure without crossing over impervious area. Approximately 300 square feet of clearing grasses and other vegetation is required for the on grade stair installation. The vertical ladder that is proposed as access from the landing to the outfall will be anchored to the existing apron slab and concrete wing wall to utilize existing structures and to prevent further disturbance in and at the water structure. C. The 2016 Small Drainage Project has identified and called out required erosion control and property restoration within the Contract Documents. The Contractor will restore any vegetation and cap graded subgrade surface with rip rap or applicable ground cover to prevent bank erosion. The slope will be in stable condition before the project is considered substantially complete. D. This Outfall access stairway is proposed primarily for maintenance access to ensure the outfall is in working condition. The City of Tukwila and any other municipalities caring for the Green River trail that parallels the bank of the river will be able to continue their care, preservation, and maintenance of the Green River Trail and vicinity once this outfall access has been constructed and completed. The trail will be open to the Public outside of construction hours and the Contractor will communicate with the City of Tukwila if any maintenance of the surrounding banks need to be completed during the construction phase. E. Rip Rap or the applicable ground cover will be utilized as property restoration at the conclusion of the project. Planting trees is not permitted within the limits of the outfall or Tukwila 205 Levee system. The City of Tukwila is committed to providing riverbank vegetation where feasible and has implemented a new annual project beginning in 2017 called Green the Green. This project has programed between $20K and $25K per year for the next six years to implement a planting program in areas along the Green and Duwamish River where trees can be planted. The funding comes from the City Storm Water fund and is intended to help mitigate for impacts related to storm water outfalls and levees where vegetation is not permitted. Staff will also seek grant funding using the City funds for grant matching to allow larger planting efforts. A pilot project was initiated in late 2015 and 100 Douglass fir saplings were planted by City staff. Trees planted will be monitored to determine the overall survivorship and help guide future planting efforts. CPL Page 12 of 13 C:\Users\ryan-1\Desktop\Shoreline Sub Dev July 2016.docx F. The City of Tukwila and remaining vested individuals on this project will be inspecting and monitoring the construction of the Gilliam Creek Outfall Access to ensure all construction near the water structure meets the regulations and guidelines of the SEPA and HPA.

SHORELINE GOALS AND POLICIES The goals and policies listed below are taken from the City's 1995 Comprehensive Plan. Strikeout/underlining has been used to indicate proposed revisions to the original 1995 text to reflect changed circumstances or newer requirements. The goals and policies are found in Chapter 5 of the Comprehensive Plan. The Comprehensive Plan will be amended to reflect these changes to goals and policies. 6.1 Shoreline Environment Designations, Comprehensive Plan Goal 5.1 Goal: Shoreline Environment designations that meet Washington State Shoreline Management Act requirements, and reflect local conditions and Tukwila's long-term vision for its shoreline. The shoreline jurisdiction generally extends for 200 feet on either side of the Ordinary High Water mark, consistent with the Washington State Shoreline Management Act. In order to implement this goal, the SMP proposes three Environment Designations: Shoreline Residential, Urban Conservancy, and High Intensity (as detailed in the Shoreline Environment Section) that comply with the Washington State Shoreline Management Act and function well for the City. Policies: • Policy 5.1.1: Shoreline Residential Environment. In the Shoreline Residential Environment, priority shall be given to the following: o Uses that preserve or restore the natural character of the shoreline or promote preservation of vegetation, open space, flood plain or sensitive area lands; and o Development that is compatible with the natural and biological limitations of the land and water and that will not require extensive alteration of the shoreline or new "hard" structural shoreline stabilization. Where possible the removal of bulkheads, revetments, levees or other "hard" structural shoreline stabilization is required. Hard structural shoreline stabilization may be replaced with alternative bioengineered bank stabilization; and o On publicly owned property, water -dependent or water -related recreational activities that are compatible with the character of the shoreline residential areas. o Maintenance of existing single-family residential development patterns and public open space and recreation uses; o Residential and recreational development that promotes vegetation conservation and enhancement, sensitive areas protection, and maintenance of water quality to assure no net loss of shoreline ecological functions; o Residential and recreational development that contributes to the restoration of ecological functions over time in areas where ecological degradation has occurred. CL 35 08/16/2011 9:41 AM W:\Long Range Projects\Shoreline\Council Review 2\\Council Adopted SMP- w Housekeeping Edits -Attach A • Policy 5.1.2, Urban Conservancy Environment: In the Urban Conservancy Environment priority shall be given to the following: o Development that promotes vegetation conservation and enhancement, sensitive areas protection, and preservation of water quality to assure no net loss of shoreline ecological functions. o Water enjoyment uses o Uses that remove shoreline armoring, unless required for a shoreline dependent use, and uses that prevent and/or minimize flood damage; o Uses that preserve or restore shoreline ecological functions provided by vegetation, open space, flood plain or sensitive area lands; o Uses that minimize interference with navigation and flood control, consider impacts to public views, and allow for the safe, unobstructed passage of fish and wildlife, particularly those species dependent on migration; o Uses that provide public access and public recreation whenever feasible and when ecological impacts can be mitigated; o Development that is compatible with the natural and biological limitations of the land and water that do not require extensive alteration of the shoreline or new shoreline stabilization, except for restoration projects. o Uses that provide public access and public recreation whenever feasible and ecological impacts can be mitigated; o Enhancement and restoration of ecological functions; and o Redevelopment of underutilized areas and development of commercial and industrial activities where shoreline impacts are minimized and where there is no net loss of shoreline functions. • Policy 5.1.3, High Intensity Shoreline Environment: In the High Intensity Environment, priority shall be given to the following: o Water dependent commercial and industrial uses; o Development that promotes vegetation conservation and enhancement, sensitive areas protection, and preservation of water quality to assure no net loss of shoreline ecological functions. o Uses that remove shoreline armoring, unless required for a shoreline dependent use, and uses that prevent and/or minimize flood damage; o Uses that preserve or restore shoreline ecological functions provided by vegetation, open space, flood plain or sensitive area lands; o Uses that minimize interference with navigation and flood control, consider impacts to public views, and allow for the safe, unobstructed passage of fish and wildlife, particularly those species dependent on migration; o Uses that provide public access and public recreation whenever feasible and when ecological impacts can be mitigated; CL 36 08/16/2011 9:41 AM W:\Long Range Projects`Shoreline\Council Review 2\\Council Adopted SMP- w Housekeeping Edits -Attach A o Development that is compatible with the natural and biological limitations of the land and water that do not require extensive alteration of the shoreline or new shoreline stabilization, except for restoration projects. o Uses that provide public access and public recreation whenever feasible and ecological impacts can be mitigated; o Enhancement and restoration of ecological functions; and o Redevelopment of underutilized areas and development of intensive commercial and industrial activities where shoreline impacts are minimized and where there is no net loss of shoreline functions. New policy 5.1.4: Shoreline Aquatic Environment. In the Shoreline Aquatic Environment, priority shall be given to the following: • Uses that preserve or restore the natural character of the shoreline or promote preservation of vegetation, open space, flood plain or sensitive area lands; • Water dependent uses • Uses that remove shoreline armoring, unless required for a shoreline dependent use, and uses that prevent and/or minimize flood damage; • Uses that minimize interference with navigation and flood control, consider impacts to public views , and allow for the safe, unobstructed passage of fish and wildlife, particularly those species dependent on migration; • Uses that provide public access and public recreation whenever feasible and ecological impacts can be mitigated; • Development that is compatible with the natural and biological limitations of the land and water that do not require extensive alteration of the shoreline or new shoreline stabilization, except for restoration projects. • Enhancement and restoration of ecological functions. • Uses compatible with the adjoining shoreline environments. 6.2 Shoreline Planning and Management, Comprehensive Plan Goal 5.2 Goal: Expanded value of the river as a community and regional resource through regional coordination of shoreline management programs and through programs that foster river appreciation and awareness, involving partnerships among businesses, schools, government and community organizations. Policies: • Policy 5.2.1: Coordinate shoreline planning and management activities with other local jurisdictions and their plans such as the WRIA 9 Salmon Habitat Plan and the King County Flood Hazard Management Plan to establish region -wide consistency in addressing river issues with regional implications, such as economic development, public access, wildlife habitat, water quality control and flood control. CL 37 08/16/2011 9:41 AM W:\Long Range Projects \Shoreline \Council Review 2\\Council Adopted SMP- w Housekeeping Edits -Attach A • Policy 5.2.2: Promote river stewardship and increase river awareness through actions which further shoreline goals, such as educational programs, community activities, and partnerships with Tukwila residents, businesses, schools, government, and community organizations. • Policy 5.2.3: Promote and participate in the implementation of the Watershed Resource Inventory Area (WRIA) 9 Plan, including supporting the recommended projects located in Tukwila to improve the habitat functions of the Green/Duwamish River, as well as the Plan policies and goals. C. Implementation Strategies: • WRIA 9 Salmon Habitat Plan • Tukwila SMP Restoration Plan • King County Flood Hazard Management Plan 6.3 Land Development Use and Economic Vitality.

The purpose of environmental review is to identify a proposal's significant adverse impacts, measures to minimize or avoid such impacts, and allow wide public review for a wide range of projects. REQUIREMENTS: SEPA review is required for any action associated with the following types of decisions: 1. Developing 10 or more dwelling units. 2. Developing agricultural structures over 10,000 s.f. 3.
