REPORT TO THE HEARING EXAMINER Hearing Date: November 9, 2021 Project File Number: PR21-000102 Project Name: SPU Broodstock Collection Facility Replacement Land Use File Number: LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Project Manager: Alex Morganroth, Senior Planner Owner: City of Renton, 1055 S Grady Way, Renton Applicant/Contact: Tessa Gardner, Floyd Snider / 601 Union Ave, Seattle, WA 98101 /tessa.gardner- brown@floydsnider.com Project Location: 1715 Maple Valley Hwy (APN 1723059013, 1723059014), Cedar River Mile 1.7 Project Summary: The applicant is requesting Hearing Examiner Site Plan Review, a Hearing Examiner Conditional Use Permit, a Shoreline Substantial Development Permit, a Shoreline Conditional Use Permit, and a Shoreline Variance in order to replace the existing sockeye salmon broodstock collection facility (BCF). The City of Seattle, acting as the SEPA lead agency, issued a Determination of Non-Significance on October 22, 2020. No appeals were filed. The project site is at River Mile 1.7 of the Cedar River in Renton, Washington, immediately upstream of WSDOT’s I-405 bridge over the Cedar River. Development would occur in the Cedar River and along its south bank on parcel 1723059014 owned by the City of Renton. There is no site address associated with this parcel. Work would also occur on WSDOT-owned parcel 1723059179 where development would widen an existing access road. Both upland sites are located in the Commercial-Office-Residential (COR) zone and are designated Commercial-Office-Residential (COR) in the City’s Comprehensive Plan. The existing parking lot on the parcel would be used temporarily for construction staging. Construction access/staging would also occur on the north side of the river on parcel 1723059013 (Cedar River Park) owned by the City of Renton and in WSDOT right-of-way for I-405. In 2008, Seattle Public Utilities constructed the original BCF at river mile 1.7 on the Cedar River, within the City of Renton. The BCF was constructed to facilitate on-going fish collection activities in support of the Cedar River Hatchery, located upstream. The Cedar River Hatchery program was established to satisfy terms of the Landsburg Mitigation Agreement, which is intended to mitigate for habitat loss for sockeye salmon above the Landsburg Diversion Dam. The purpose of the BCF Replacement Project is to replace the existing BCF with a new facility. Replacement is expected to improve operations at higher river flows, which will help to fulfill the goal of sufficient genetic diversity over a longer Sockeye collection period for the Cedar River Hatchery, given the ability to operate later into the season. Replacement of the existing BCF will also improve safety for facility operators by minimizing operational maintenance needs. Work proposed by the applicant includes construction of a new in-water concrete sill on the bed of the Cedar River, construction of a new concrete retaining wall to support the boat ramp on the south side of the river, reconstruction of a portion of the boat ramp below the OHWM, and widening of the access road that connects the boat ramp to Houser Way S. During construction, the site would be accessed via both the boat ramp access road on the south of the river and Cedar River Park Dr on the north City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 2 of 40 SR_HEX Broodstock_211101 side of the drive. Staging of equipment would occur on both sides of the river. Project construction would occur over two seasons starting in late spring 2022 and ending in the fall of 2023. The applicant anticipates no net loss of ecological functions and proposes the construction of riparian and channel margin enhancement on a 10,900 sq. ft. of low flood terrace and gravel bar near the project site. In addition, the applicant has proposed the installation of large woody material to increase aquatic habitat complexity, removal of invasive species, and planting of native trees and shrubs. Critical areas on the site include sensitive slopes, steep slopes, a high seismic hazard area, a habitat conservation area, the wellhead protection area zone 1, and a flood hazard area. The site also located within Reach C of the Cedar River regulated shoreline area and includes the Urban Conservancy, High Intensity, and Aquatic Shoreline designations. The applicant submitted a biological assessment, drainage report, critical areas report, and geotechnical report with the project application.

Zoning Development Standard Compliance: The purpose of the Commercial Office Residential Zone (COR) is to provide for a mix of intensive office, hotel, convention center, and residential activity in a high-quality, master-planned development that is integrated with the natural environment. Commercial retail and service uses that are architecturally and functionally integrated are permitted. Also, commercial uses that provide high economic value may be allowed if designed with the scale and intensity envisioned for the COR Zone. The scale and location of these sites will typically denote a gateway into the City and should be designed accordingly. The proposal is compliant with the following development standards, as outlined in RMC 4-2-120.B, if all conditions of approval are met: Compliance COR Zone Develop Standards and Analysis Compliant if CUP under FOF 19 approved Use: Pursuant to RMC 4-2-060, Zoning Use Table – Uses Allowed in Zoning Designations, natural resource extraction/recovery uses are permitted in the COR zone provided with an approved Hearing Examiner Conditional Use Permit. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 7 of 40 SR_HEX Broodstock_211101 Staff Comment: The applicant, Seattle Public Utilities, is proposing to replace an existing sockeye salmon broodstock collection facility (BCF) originally approved under LUA08-018. A BCF is not a use type listed in the City’s Zoning Use Table codified in RMC 4 -2-060. The use type determined to be the most similar to a BCF in the 2008 decision was a natural resources extraction/recovery use. Natural resources extraction/recovery uses are allowed as a Hearing Examiner Conditional Use in the COR zone. See FOF 19: Conditional Use Permit Analysis. N/A Density: The density range permitted in the COR zone is a minimum of 30 up to a maximum of 50 dwelling units per net acre. The same area used for commercial and office development can also be used to calculate residential density. Where commercial and/or office areas are utilized in the calculation of density, the City may require restrictive covenants to ensure the maximum density is not exceeded should the property be subdivided or in another manner made available for separate lease or conveyance. Density may be increased 30-percent above the maximum per RMC 4-9- 065, Density Bonus Review. Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way, and private access easements. Staff Comment: No dwelling units are proposed as part of the project. ✓ Setbacks: Setbacks in the COR zone are determined through site plan review. Staff Comment: The type of development, which is primarily in-water, does not have dimensional standards attributed to it and therefore does not have traditional setbacks. See additional analysis under FOF 20.b.6. N/A Building Standards: The maximum lot coverage requirements for buildings in the COR zone is 65 percent of the total lot area or 75 percent is parking is provided within the building or within a parking garage. The maximum building height permitted is 10 stories and/or 125 feet. Staff Comment: No buildings are proposed as part of the project. ✓ Landscaping: The City’s landscape regulations (RMC 4-4-070) require a 10-foot landscape strip along all public street frontages. Additional minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060. Street trees and, at a minimum, groundcover, are to be located in this area when present. Spacing standards shall be as stipulated by the Department of Community and Economic Development, provided there shall be a minimum of one street tree planted per address. Any additional undeveloped right-of- way areas shall be landscaped unless otherwise determined by the Administrator. Staff Comment: The proposed project would occur entirely within designated critical areas, therefore no landscaping required. In addition, the project does not have street frontage and does not include any surface parking lots. The applicant has proposed plantings along the south shoreline of the Cedar River as part of the shoreline mitigation plan (Exhibit 4). Plantings proposed as part of the restoration and mitigation plan include native species such as Black cottonwood, Red alder, Pacific willow, Snowberry, Nootka rose, Salmonberry, and Pacific ninebark. ✓ Tree Retention: The City’s adopted Tree Retention and Land Clearing Regulations (4-4- 130) require the retention of 10 percent of trees in a commercial or industrial development. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 8 of 40 SR_HEX Broodstock_211101 Significant trees shall be retained in the following priority order: Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than twenty percent (20%); significant trees adjacent to critical areas and their associated buffers; and significant trees over sixty feet (60') in height or greater than eighteen inches (18") caliper. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non-native trees. Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. Staff Comment: The applicant has proposed the removal of one 36-inch DBH Black cottonwood tree in order expand the width of the existing boat ramp. Due to the large number of trees on the site and the fact that the applicant is only proposing to remove a single tree, staff did not require the applicant to submit a formal tree survey or tree retention worksheet. Based on the recent aerial imagery and the mitigation plan submitted by the applicant (Exhibit 4), each which 100+ trees across the upland portion of the site, the project would comply with the tree retention standards for commercial or industrial development. N/A Screening: All on-site surface mounted utility equipment shall be screened from public view. Screening shall consist of equipment cabinets enclosing the utility equipment, solid fencing or a wall of a height at least as high as the equipment it screens, or a landscaped visual barrier allowing for reasonable access to equipment. Equipment cabinets, fencing, and walls shall be made of materials and/or colors compatible with building materials. All operating equipment located on the roof of any building shall be enclosed so as to be screened from public view. Staff Comment: The proposed project does include any on-site surface mounted utility equipment and therefore no screening is required. N/A Refuse and Recycling: All new developments for multi-family residences, commercial, industrial and other nonresidential uses shall provide on-site refuse and recyclables deposit areas and collection points for collection of refuse and recyclables in compliance. Staff Comment: Due to the unique nature of proposed BCF, a natural resource extraction facility, no trash or recycling waste would be generated and therefore no refuse or recycling facilities are required. N/A Parking: Off-street parking, loading areas, and driveways shall be provided in accordance with the provisions of RMC 4-4-080 for all new building or structures when located outside of the Center Downtown Zone. Staff Comment: Due to the unique nature of proposed BCF, an in-water structure, no parking is proposed as part of the project. When parking is needed for maintenance or removal of the weir during seasonal operation, the applicant’s contractors currently utilize the existing parking at the Cedar River Trail trailhead adjacent to the site. The applicant has indicated they will continue to utilize the trailhead parking lot after completion of the replacement BCF. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 9 of 40 SR_HEX Broodstock_211101 Compliant if Condition of Approval is met Access: Direct arterial access to individual structures shall occur only when alternative access to local or collector streets or consolidated access with adjacent uses is not feasible. Staff Comment: The site is currently accessed via a City-maintained paved private road off of Houser Way S, which provides public access to both the boat launch and dog park near the site. The applicant has proposed to widen a portion of the road between the boat launch and spur intersection where the road splits. The road would be widened by approximately 3 feet for a total width of 18 feet. No direct arterial access would occur for the proposed BCF replacement and access to the site would not be changed as a result of the project. Under the previous BCF, the applicant was required to adhere to the Cedar River Access Facility Management Plan, dated June July 30, 2008. Due to the change location and characteristics of the facility, a new access plan should be prepared. Therefore, staff recommends, as a condition of approval, the applicant shall enter into a new Access Facility Management Plan with the City prior to the issuance of the civil construction permit. N/A Bicycle Parking: Attached dwellings shall provide one-half (0.5) bicycle parking space per one dwelling unit. Commercials uses shall provide bicycle parking spaces equal to ten percent (10%) of the number of required off-street vehicle parking spaces. Staff Comment: See analysis under FOF 17, Parking above. ✓ Pedestrian Access: Pedestrian access is determined through site plan review. Staff Comment: See FOF 18.g below for analysis. N/A Upper Story Setbacks: Buildings or portions of buildings that exceed fifty feet (50') in height shall include upper story setbacks as follows: The minimum setback for a fifth story and succeeding stories shall be ten feet (10') minimum from the preceding story, applicable to each story or an equivalent standard that adds interest and quality to the building. Staff Comment: No buildings are proposed as part of the project. N/A Roofline and Façade Modulation: Buildings shall provide vertical and horizontal modulation of roof lines and facades of not less than two feet (2') at a minimum interval of forty feet (40') per building face, or an equivalent standard that adds interest and quality to the building. Staff Comment: No buildings are proposed as part of the project. N/A Fences and Retaining Walls: A maximum of eight feet (8') anywhere on the lot provided the fence, retaining wall or hedge does not stand in or in front of any required landscaping or pose a traffic vision hazard. There shall be a minimum three-foot (3') landscaped setback at the base of retaining walls abutting public rights-of-way. Staff Comment: No fencing is proposed as part of the project. 18. Site Plan Review: Pursuant to RMC 4-9-200.B, Site Plan Review is required for development in the COR zoning classification when it is not exempt from Environmental (SEPA) Review. For Master Plan applications compliance with the review criteria for Site Plans are analyzed at a general level of detail to ensure nothing City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 10 of 40 SR_HEX Broodstock_211101 would preclude the development of the Site Plan. Given Site Plan applications are evaluated for compliance with the specific requirements of the RMC 4-9-200.E.3 the following table contains project elements intended to comply with level of detail needed for Site Plan requests: Compliance Site Plan Criteria and Analysis ✓ a. Comprehensive Plan Compliance and Consistency. Staff Comment: See previous discussion under FOF 16, Comprehensive Plan Analysis. ✓ b. Zoning Compliance and Consistency. Staff Comment: See discussion under FOF 17, Zoning Development Standard Compliance. N/A c. Design Regulation Compliance and Consistency. Staff Comment: Given the nature of the proposed project, which has no architectural, design, or specific landscaping elements due its location in the Cedar River regulated shoreline area, the Urban Design Regulations are not applicable. N/A d. Planned action ordinance and Development agreement Compliance and Consistency. ✓ e. Off-site Impacts. Structures: Restricting overscale structures and overconcentration of development on a particular portion of the site. Staff Comment: No buildings are proposed as part of the project. The only structure proposed as part of the BCF, the concrete sill, is located in the river itself. No other structures are proposed for the upland area and therefore the project would not result in overscale structures or an overconcentration of development on any portion of the site. Circulation: Providing desirable transitions and linkages between uses, streets, walkways and adjacent properties. Staff Comment: The proposed project would not alter the existing circulation patterns on the project site. The existing public access from the Cedar River Trail to the access road and boat ramp on the south bank of the Cedar River would be maintained. Utilities, Loading and Storage Areas: Locating, designing and screening storage areas, utilities, rooftop equipment, loading areas, and refuse and recyclables to minimize views from surrounding properties. Locate utilities underground consistent with RMC 4-6-090. Staff Comment: The proposed project would require installation of electrical conduit, which would be placed underground within the footprint of the existing access road leading to the boat ramp. No loading or storage areas are proposed as part of the project. Views: Recognizing the public benefit and desirability of maintaining visual accessibility to attractive natural features. Staff Comment: The proposed project would not establish a new use or development, as the proposed project intends to replace an existing facility that is seasonally part of the visual landscape and is often visited by community members to observe natural City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 11 of 40 SR_HEX Broodstock_211101 salmonid migration and the associated fish-handling. Seasonal operation of the above- water facilities would not preclude the public’s visual access to the shoreline due to the in-water nature of the structure. The replacement BCF would continue to add interest and educational opportunities related to the natural environment for the life of the project. Landscaping: Using landscaping to provide transitions between development and surrounding properties to reduce noise and glare, maintain privacy, and generally enhance the appearance of the project. Staff Comment: Traditional landscaping is not proposed as part of the project due to the entire project site being located in the regulated shoreline area. The applicant has proposed a mitigation plan (Exhibit 4) that includes a significant amount of additional vegetation on the south side of the upland area from the Cedar River. The additional vegetation will result in reduced noise and glare once mature and will enhance the appearance and functionality of the shoreline. See additional discussion under FOF 17, Zoning Development Standard: Landscaping. Lighting: Designing and/or placing exterior lighting and glazing in order to avoid excessive brightness or glare to adjacent properties and streets. Staff Comment: The proposed project includes installation of one 14-foot tall light pole to the north of the existing boat ramp appropriately 15 feet north of an existing downward shielded light pole used to light the boat ramp area. The light would be utilized only during emergencies and to improve safety during low light conditions if emergency maintained for the BCF is needed. Given the limited anticipated use for this light and existing lights on site, no excessive light and glare impacts are anticipated. A lighting plan was not provided with the application. ✓ f. On-site Impacts. Structure Placement: Provisions for privacy and noise reduction by building placement, spacing and orientation. Staff Comment: The permanent concrete sill and retaining wall structure, as well as the seasonally-installed picket weir panels and trap box, are located in-water and would operate silently. The weir panels would be activated via an electronic actuator system that would not be audible to nearby properties over sound of the river and other noises typically found in an urban environment. Therefore, the proposed BCF would not create privacy or noise impacts. Structure Scale: Consideration of the scale of proposed structures in relation to natural characteristics, views and vistas, site amenities, sunlight, prevailing winds, and pedestrian and vehicle needs. Staff Comment: Permanent structures would include a concrete sill, a concrete retaining wall located below ground surface, one light pole, a grasscrete pad adjacent to the boat ramp to support the crane outriggers during weir installation, and the widened/reconfigured access road. These elements are similar to the existing structural elements on site being replaced and would not result in scale-related impacts to the natural or built environments. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 12 of 40 SR_HEX Broodstock_211101 Natural Features: Protection of the natural landscape by retaining existing vegetation and soils, using topography to reduce undue cutting and filling, and limiting impervious surfaces. Staff Comment: Where possible, the applicant has indicated the intent to utilize existing infrastructure on the site as much as possible in order to minimize the need to alter natural features. Impervious surfaces have been minimized through removal of a portion of the existing boat ramp and utilizing grasscrete pavers to support the installation crane outriggers instead of concrete. In addition, the slopes on site will be improved as part of the mitigation plan (Exhibit 4) proposed by the applicant, resulting in reduced erosion during rain and flood events. Minimal upland grading is proposed as part of the project. Reducing Parking Impervious Areas: Design parking areas to minimize impervious surfaces, including but not limited to: (1) breaking up parking areas and directing stormwater flows to multiple low impact development features such as bioretention areas; (2) locating parking near trees to provide storm water uptake; (3) retaining or adding vegetation to parking areas; (4) placing existing parking that exceeds maximum parking ratios in permeable pavement designed consistent with the Surface Water Design Manual in RMC 4-6-030; and (5) using other low impact development techniques consistent with RMC 4-6-030 Staff Comment: No new or expanded parking areas are proposed. Grasscrete pavers, partially pervious materials, would be utilized for the crane outrigger pad located adjacent to the boat ramp and will reduce the amount of impervious concrete on the site after project completion. Landscaping: Use of landscaping to soften the appearance of parking areas, to provide shade and privacy where needed, to define and enhance open spaces, and generally to enhance the appearance of the project. Landscaping also includes the design and protection of planting areas so that they are less susceptible to damage from vehicles or pedestrian movements. Staff Comment: See FOF 17, Zoning Development Standards: Landscaping and FOF 18, Off-site Impacts: Landscaping for analysis. ✓ g. Access and Circulation. Location and Consolidation: Providing access points on side streets or frontage streets rather than directly onto arterial streets and consolidation of ingress and egress points on the site and, when feasible, with adjacent properties. Staff Comment: See FOF 17, Zoning Develompent Standards: Access for analysis. Internal Circulation: Promoting safety and efficiency of the internal circulation system, including the location, design and dimensions of vehicular and pedestrian access points, drives, parking, turnarounds, walkways, bikeways, and emergency access ways. Staff Comment: The proposed project does not include new access or circulation routes; existing transportation infrastructure would be utilized. Loading and Delivery: Separating loading and delivery areas from parking and pedestrian areas. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 13 of 40 SR_HEX Broodstock_211101 Staff Comment: Due to the nature of the use, no deliveries are anticipated and therefore no loading or delivery area is proposed. Transit and Bicycles: Providing transit, carpools and bicycle facilities and access. Staff Comment: Due to the nature of the use, the provision of additional transit facilities is not appropriate. During and after completion of the project, park users will continue to have access to shoreline via existing bus routes, parking facilities, and bicycle racks provide by the city on the north side of river adjacent to the site. Pedestrians: Providing safe and attractive pedestrian connections between parking areas, buildings, public sidewalks and adjacent properties. Staff Comment: Pedestrian connections to and on the project site would not be impacted as a result of the project. Existing sidewalks along Houser Way S provide access to the upland portions of the site, and an on-site pedestrian pathway is located on the Renton Community Center site to the north. ✓ h. Open Space: Incorporating open spaces to serve as distinctive project focal points and to provide adequate areas for passive and active recreation by the occupants/users of the site. Staff Comment: The purpose of the proposed project is to replace an existing fish collection facility, which is jointly operated by SPU and the WDFW as part of the Hatchery Program. The replacement BCF does not include the creation of new open spaces. Existing open space on both the south and north upland portions of the site would not be impacted by the project. ✓ i. Views and Public Access: When possible, providing view corridors to shorelines and Mt. Rainier, and incorporating public access to shorelines Staff Comment: The proposed project would not negatively impact existing view corridors. Expansions to existing view corridors are not proposed because that would require tree or vegetative removal within critical areas. Public access to the shoreline would be maintained, including the boat ramp, which is consistent with the existing site conditions. ✓ j. Natural Systems: Arranging project elements to protect existing natural systems where applicable. Staff Comment: Given the proposed project’s reliance on an in-water location, locating construction outside of natural areas is not feasible. However, the applicant has attempted to minimize the project footprint by removing portions of the existing boat ramp and utilizing grasscrete pavement where feasible to reduce pollution generating runoff into the river. ✓ k. Services and Infrastructure: Making available public services and facilities to accommodate the proposed use: Police and Fire. Staff Comment: Police and Fire Prevention staff indicated that sufficient resources exist to furnish services to the proposed development; if the applicant provides Code required improvements and fees. Water and Sewer. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 14 of 40 SR_HEX Broodstock_211101 Staff Comment: Due to the nature of the project, water and sewer service is not required. Drainage. Staff Comment: The proposed project would create approximately 1,922 sq. ft. of new and replaced impervious surface. The applicant submitted a preliminary Technical Information Report prepared by McMillen Jacobs Associates, dated January 31, 2020 (Exhibit 7) with the application. Based on the location of the site, the project will be subject to Targeted Level 1 review. A final Technical Information Report submitted with the civil construction permit application shall include qualitative and quantitative analysis demonstrating compliance with the Water Resource Inventory Area (WRIA) 8 Chinook Salmon Conservation Plan, which should address the direct impacts of the development on salmon, salmonoid and spawning habitat as it relates to water quality, discharges, pollutants, and increased volumes along the projects shoreline and associated drainage basin. Staff will review both final report during the Construction Permit application review process to determine if the project conforms with the 2017 Renton Surface Water Design Manual. Transportation. Staff Comment: Access to the site is proposed via an existing private road off of Houser Way S. See FOF 17, Zoning Develompent Standards: Access for additional analysis. No additional trips are antifipated as result of the project. ✓ l. Phasing: Staff Comment: Project construction would occur in two phases, with Phase 1 in 2022 and Phase 2 in 2023. In-water work would occur within the allowable work window each year, which extends from July 1 to August 31. A 1-month extension to the work window is requested, with work beginning June 1. Upland work would not be confined to the work window but is generally expected to coincide with in-water activities or be phased just before and after. Phase 1 consists of all work on the south side of the Cedar River, which includes all upland work and construction of approximately half of the concrete sill, extending from the south bank of the river to just past mid-channel. Phase 2 includes in-water construction of the north half of the concrete sill, facilitated from the Park on the north bank of the river. ✓ m. Stormwater: Providing optimal locations of stormwater infiltrating low impact development facilities. Avoiding placement of buildings or impervious areas on soils with infiltration capability to the maximum extent practicable. Staff Comment: The proposed project is reliant on proximity to the Cedar River and would be replacing an existing facility at the same location. Therefore, the location of new impervious areas was predetermined by the functional needs of the replacement BCF, regardless of soil infiltration capacity at the site. However, the proposed project does include grasscrete pavers in lieu of concrete in order to minimize the amount of impervious surfaces at the site. In addition, the plantings proposed as part of the mitigation plan (Exhibit 4) will provide water uptake and increase the water capacity of the soil. No other stormwater facilities are proposed or required in order to manage stormwater on the site. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 15 of 40 SR_HEX Broodstock_211101 19. Conditional Use Analysis: The applicant is requesting a Hearing Examiner Conditional Use Permit to operate a natural resource extraction/recovery use in the COR zone. The proposal is compliant with the following conditional use criteria, pursuant to RMC 4-9-030.D. Therefore, staff recommends approval of the requested Conditional Use Permit. Compliance Conditional Use Criteria and Analysis ✓ a. Consistency with Plans and Regulations: The proposed use shall be compatible with the general goals, objectives, policies and standards of the Comprehensive Plan, the zoning regulations and any other plans, programs, maps or ordinances of the City of Renton. Staff Comment: See FOF 16 AND 17 for Comprehensive Plan and zoning regulation compliance. ✓ b. Appropriate Location: The proposed location shall not result in the detrimental overconcentration of a particular use within the City or within the immediate area of the proposed use. The proposed location shall be suited for the proposed use. Staff Comment: The proposed replacement BCF is one of only two natural resource extraction/recovery uses in the City of Renton, the other of which is located over a mile to the west and is not related to the collection of salmonids. Therefore, both the existing and proposed replacement BCF facility are extremely unique uses that are not over- concentrated within a particular area of the city. The project location is well suited for the replacement BCF, as an existing BCF and the associated infrastructure to serve the new facility is already in place and requires only moderate impacts to the river and upland area when compared to establishing an entirely new location for the facility. The purpose of the BCF, to collect salmonids, is inherently reliant on being locate at an in- water location where salmon spawn, and therefore the Cedar River is an ideal location. Lastly, the location is well-suited due to the established relationship between City of Renton and SPU have with respect to the operation of a natural resource extraction/recovery use at the site. ✓ c. Effect on Adjacent Properties: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. Staff Comment: The applicant contends that the proposed project would maintain the existing use at the site and operate at a substantially similar scale and therefore would not result in use-related impacts on adjacent properties. Although staff agrees that the impacts of the replaced BCF would be substantially similar to the ones created by the existing BCF, the new facility should be evaluated on its own merits if approved under a new CUP. The nearest residential use, a single-family home, is located approximately 400 ft south of the project site and is separated from the site by a severe topographical change and forested area. Impacts from seasonal traffic associated with fish hauling and weir installation would not impact adjacent properties as they are not served by Houser Way S or the internal access road leading to the BCF. Lastly, no commercial or residential uses are located near the site. The Renton Community Center located north of the river is the nearest other use, but would not be impacted by the BCF due to its in- water location and fact that the BCF would only be accessed via the boat access road south of the river. Therefore, staff concurs that the use would not result in substantial or undue adverse effects on adjacent properties. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 16 of 40 SR_HEX Broodstock_211101 ✓ d. Compatibility: The proposed use shall be compatible with the scale and character of the neighborhood. Staff Comment: The applicant contends that the scale of the physical and operational characteristics of the replacement BCF would remain substantially the same as the existing BCF, which have not created any compatibility issues since being installed in 2009. The surrounding neighborhood is primarily undeveloped in nature due to the restrictive Resource Conservation (RC) zoning designation, except for the Renton Community Center located on the north side of the river approximately 450 feet from the existing and proposed BCF. Due to the in-water nature of improvements, limited visual impact, non-residential nature of the surrounding area, staff concurs that the proposed natural resource extraction/recovery use would be compatible with the scale and character of the neighborhood. ✓ e. Parking: Adequate parking is, or will be made, available. Staff Comment: The proposed project does not require or propose new formal parking stalls. When parking is required during seasonal operation, existing parking at the Cedar River Trail trailhead is utilized per the existing Memorandum of Agreement between the City of Renton and SPU. Compliant if Condition of Approval is met f. Traffic: The use shall ensure safe movement for vehicles and pedestrians and shall mitigate potential effects on the surrounding area. Staff Comment: According to the applicant, traffic associated with the BCF is primarily seasonal, with peak trips occurring during non-peak recreational months. During operation, a fish hauling truck would access the site to collect and transport salmon broodstock to the hatchery upstream. The signs utilized by the existing facility, which are mounted in both directions on the Cedar River Trail warning users approaching the site of potential truck crossings ahead, would be retained to control potential conflicts between trucks and pedestrians/bicyclists. After the fish collection season, up to one truck may visit the site weekly for maintenance lasting a few hours. The applicant contends that project construction would result in a temporary increase of traffic compared to the existing conditions at the site. While staff concurs that the traffic impacts from seasonal fish collection and weekly maintenance is a limited impact reflecting a continuation of the current traffic patterns, the potential for traffic impacts during the two construction seasons is substantially greater. The Renton Community Center and the Cedar River Park on the north side of the river adjacent to the BCF host a variety of annual events that draw large crowds of residents and visitors. One event, the Renton River Days festival that is typically held in the last weekend of July, draws thousands of visitors to the banks of the Cedar River and is an important event for the City. In order to ensure that construction of the replacement BCF does not disrupt or create dangerous conditions at the various events, staff recommends, as a condition of approval, no construction shall occur during the Renton River Days festival, or any other City-sponsored event held at the Cedar River Park or Renton Community Center. Any construction-related activities shall cease at least two (2) days before the scheduled event and shall not continue until at least two (2) days after the event concludes, unless an alternate timeline is approved by Community Services Administrator. The applicant shall contact the City’s Community Services Department a minimum of two (2) weeks prior to any event to ensure the site is safe and secure for event attendees. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 17 of 40 SR_HEX Broodstock_211101 ✓ g. Noise, Light and Glare: Potential noise, light and glare impacts from the proposed use shall be evaluated and mitigated. Staff Comment: The applicant contends the replacement BCF consists of passive structures that would not produce noticeable noise. In addition, ambient noise produced by vehicles traveling I-405 and rushing water in the Cedar River would serve to drown out. While one new light pole is proposed, the light would be utilized only during emergencies or if needed to improve safety during low light conditions. According to the applicant, there are also three (3) existing light poles on site to illuminate the boat launch area, so the additional light would not constitute significance to the existing lighting. Staff concurs that the proposed project would not produce adverse light or glare impacts. ✓ h. Landscaping: Landscaping shall be provided in all areas not occupied by buildings, paving, or critical areas. Additional landscaping may be required to buffer adjacent properties from potentially adverse effects of the proposed use. Staff Comment: The proposed project would occur entirely within designated critical areas. Therefore, no landscaping is proposed, except for the vegetation included as part of the mitigation plan. 20. Shoreline Master Program Regulations: The project site is located in in the Cedar River Reach C Regulated Shoreline area with three shoreline environments. The parcel on the south side of the Cedar River is in the Urban Conservancy shoreline environment, the parcel to the north is in the Shoreline High Intensity shoreline environment, and the portion of the project site waterward of the OHWM is in the Aquatic shoreline environment. Therefore the project is subject to the shoreline regulations in RMC 4-3-090 and requires a Shoreline Substantial Development Permit. SHORELINE MASTER PROGRAM CRITERA: A. COMPREHENSIVE PLAN COMPLIANCE AND CONSISTENCY, SHORELINE ELEMENT: The site is located in the Shoreline High-Intensity Overlay District. The objective of the High Intensity Overlay is to provide opportunities for large-scale office and commercial employment centers as well as multi-family residential use and public services. This district provides opportunities for water- dependent and water-oriented uses while protecting existing ecological functions and restoring ecological functions in areas that have been previously degraded. Development may also provide for public use and/or community use, especially access to and along the water's edge. The proposal is compliant with the following Shoreline policies: ✓ Policy SH-14. Shoreline use and development should be carried out in a manner that prevents or mitigates adverse impacts so that the resulting ecological condition does not become worse than the current condition. This means ensuring no net loss of ecological functions and processes in all development and use. Permitted uses should be designed and conducted to minimize, in so far as practical, any resultant damage to the ecology and environment (RCW 90.58.020). Shoreline ecological functions that should be protected include, but are not limited to, fish and wildlife habitat, food chain support, and water temperature maintenance. Shoreline processes that shall be protected include, but are not limited to, water flow; littoral drift; erosion and accretion; infiltration; ground water recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment; organic matter input; nutrient and pathogen removal; and stream channel formation/maintenance. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 18 of 40 SR_HEX Broodstock_211101 ✓ Objective SH-E. Existing economic uses and activities on the shorelines should be recognized and economic uses or activities that are water-oriented should be encouraged and supported. ✓ Policy SH-18. All economic activities on the shoreline shall provide for no net loss of ecological functions during construction and operation. B. DEVELOPMENT STANDARDS: The project site is located in in the Cedar River Reach C Regulated Shoreline area with three (3)shoreline environments. The parcel on the south side of the Cedar River is in the Urban Conservancy shoreline environment, the parcel to the north is in the Shoreline High Intensity shoreline environment, and the portion of the project site waterward of the OHWM is in the Aquatic shoreline environment, as shown on the City of Renton Shoreline Overlay Map. The following development standards are applicable to the proposal: 1. Environmental Effects: a. No Net Loss of Ecological Functions Compliant if Condition of Approval is met Shoreline use and development shall be carried out in a manner that prevents or mitigates adverse impacts to ensure no net loss of ecological functions and processes in all development and use. Permitted uses are designed and conducted to minimize, in so far as practical, any resultant damage to the ecology and environment (RCW 90.58.020). Shoreline ecological functions that shall be protected include, but are not limited to, fish and wildlife habitat, food chain support, and water temperature maintenance. Shoreline processes that shall be protected include, but are not limited to, water flow; erosion and accretion; infiltration; groundwater recharge and discharge; sediment delivery, transport, and storage; large woody debris recruitment; organic matter input; nutrient and pathogen removal; and stream channel formation/maintenance. Staff Comment: The applicant submitted a Critical Areas Report, prepared by Confluence Environmental Company and dated July 2020 (Exhibit 6). The Critical Areas Report identified both temporary and permanent impacts to the shoreline and uplands area as a result of the project. Temporary Impacts: Temporary impacts to the Cedar River are primarily related to the concrete sill construction and would include installing temporary cofferdams on both the south bank and north banks of the river in order to divert water and allow for construction of the concrete sill. The cofferdams would be installed sequentially, one during each fish window over the two-year construction period, which allows the passage of fish and minimizes the impacts of construction. Construction of the concrete sill would require the temporary excavation of approximately 1,586 sq. ft. of riverbed outside of the limits of the permanent sill footprint over the two construction phases, which would be backfilled with the scour protection boulders after completion of the project. According to the consultant, Cofferdam installation, dewatering, and streambed excavation would result in removing and/or smothering some benthic invertebrates that provide food for salmonids. Effects to aquatic macro-invertebrates from smothering would be temporary, and the river would return to natural contours following the completion of construction. According to the consultant, macro-invertebrates are expected to rapidly recolonize disturbed areas within approximately two (2) weeks to two (2) months time. Project construction would disturb the channel bed and may release periodic pulses of sediment into the water column, City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 19 of 40 SR_HEX Broodstock_211101 resulting in a temporary increase in total suspended solids (TSS) levels. Elevated TSS is most likely to occur during initial cofferdam placement and subsequent cofferdam removal and re-watering of the in-water work areas. Pulses may also occur during periodic pumping of the work area. Elevated TSS levels would be expected to last from less than 1 hour to potentially three (3) hours depending on the activity. TSS monitoring would be implemented which together with other BMPs identified of Section 4.3 of the Critical Areas Review, would help reduce adverse impacts. In order to construct the permanent civil site improvements, including the boat ramp, crane outrigger grasscrete pad, the turning area grasscrete pad, and the access road widening, clearing limits of 3,733 sq. ft. outside of the permanent infrastructure have been established. Due to flood damage occurring in February 2020, much of the proposed clearing limits is unvegetated. Presently, only sparse native shrubs and Himalayan blackberry occurs within the clearing limits and would be removed. Temporary clearing of native vegetation within the riparian buffer during construction would be restored at a 1:1 ratio with native plants appropriate for the setting. Permanent Impacts: According to the Critical Areas Report, the completed project would result in unavoidable permanent impacts to the Cedar River and the riparian buffer. The proposed BCF infrastructure would effectively result in fill impacts within the Cedar River and hardscaping within the riparian buffer. The project would directly impact the Cedar River bed through the installation of the weir sill and, to a lesser degree, the associated access structures. The presence of the sill and access structures would permanently impact approximately 2,000 sq. ft. of benthic habitat. However, the project would also remove 539 sq. ft. of the existing boat ramp below ordinary high water, for a net increase in permanent fill of benthic habitat of 1,461 sq. ft. The presence of a fixed structure in the channel has the potential to affect sediment dynamics, reduce benthic habitat productivity, and alter habitat formation/availability. The presence of the weir would reduce the long-term production of benthic and epibenthic macroinvertebrates on which juvenile Chinook salmon and steelhead feed. Given the relatively small size of the weir, the benthic macroinvertebrate production within the project area overall is not expected to be discernible and benthic productivity is not considered to be limiting for juvenile salmonid production. The amount of forage material available for juvenile salmonids is, therefore, expected to remain similar to pre-project conditions and should not result in a significant effect to fish. The presence of the weir would also reduce the long-term availability of suitable spawning substrate. The majority of Chinook salmon and steelhead spawning is thought to occur upstream of this reach of the Cedar River. Spawning habitat is also not considered to be limiting on salmonid production. Nevertheless, up to 1,835 sq. ft. of the stream bed would be precluded from spawning potential. The project would directly impact the riparian buffer from the civil site improvements and associated hardscaping. The permanent improvements from the boat ramp reconfiguration, crane pad and turning areas, and the access road widening would result in the addition of approximately 1,742 sq. ft. of hardscaping within the riparian area on the south bank. However, the project would also remove 115 sq. ft. of the existing boat ramp, for a net increase in permanent riparian hardscaping of 1,627 sq. ft. The proposed riparian hardscaping would preclude riparian vegetation growth and increase the impervious surface quantity in the riparian buffer. The inclusion of Grasscrete pavers would limit the increase in impervious surface to 495 sq. ft. associated with the boat ramp and access road improvements. Ecological functions typically provided by riparian buffers include, among others, erosion reduction, sediment and pollutant removal, wood recruitment and organic litter production/trophic support, microclimate influence, screening of adjacent disturbances (e.g., noise, light), and habitat maintenance and connectivity. Again, due to the flood damage described in Section 5.2.2, most of the area City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 20 of 40 SR_HEX Broodstock_211101 proposed for civil improvements is unvegetated. Presently, one (1) large black cottonwood tree and a small clump (approximately 100 sq. ft.) of Pacific ninebark and Himalayan blackberry would be removed. The proposed impacts would have a negligible effect on erosion control, sediment and pollutant removal, microclimate influence, screening, and habitat maintenance and connectivity. The vegetation removal would have a minor effect on organic litter production, shade, and wood recruitment. Overall, riparian buffer processes are expected to remain relatively unchanged as a result of the project. The unavoidable impacts are proposed to be offset through compensatory mitigation. Mitigation for No Net Loss: To mitigate for the temporary and permanent impacts to the Cedar River and the shoreline, the applicant proposes to conduct riparian and channel margin enhancement on a total of 10,900 sq. ft. of the low flood terrace and gravel bar at the project site. Due to recent flooding in winter 2020, existing understory vegetation and large wood debris on the flood terrace was largely washed away. Invasive species such as Japanese knotweed and Himalayan blackberry persist and are recolonizing denuded soils. To provide an aquatic component to the mitigation design, an LWM complex is proposed along the left bank to the Cedar River approximately 130 feet upstream of the proposed BCF. This complex would be partially buried and anchored into the substrate with root wads oriented toward the river to provide habitat complexity, cover, and woody substrate for algae and macroinvertebrates. Proposed riparian improvements include restoration of the 3,733 sq. ft. of temporary clearing limits, re-establishment of riparian vegetation in 489 square feet of the existing boat ramp removal, and enhancement of 6,680 sq. ft. of degraded riparian buffer. Vegetation management would include removal of invasive species and installation of native trees and shrubs suitable to the site conditions. Species proposed include Red alder, Pacific willow, Snowberry, Nootka rose, Salmonberry and Black cottonwoods. The planted area would be treated with an erosion control fabric (e.g., jute or coir) and mulching as appropriate to promote plant establishment, erosion control, and weed prevention. According to the consultant, the principal impacts associated with the proposed BCF requiring mitigation include a loss of river substrate supporting potential spawning and benthic production, and removal of riparian vegetation. These ecological functions are not considered limiting in the project reach and effects to fish production and stream ecology are not considered significant. The proposed on-site mitigation would offset the loss of these functions over time through the following effect pathways. Therefore, the report conduces that the proposed on-site mitigation would provide greater ecological benefit to the Cedar River relative to the minor loss of function due to the project impacts and therefore would result in no net loss of ecological function. Maintenance and monitoring requirements may vary between the City of Renton and the U.S. Army Corps of Engineers (USACE) regulations. In order to ensure the required reports are received by both agencies at consistent intervals and with consistent information, the applicant should comply with all report requirements from the U.S. Army Corps of Engineers. If the USACE does not require maintenance and monitoring, the applicant should default to the City of Renton’s requirements for maintenance and monitoring. Therefore, staff recommends, as a condition of approval, the applicant shall submit maintenance and monitoring reports after project completion consistent with the requirements of the USACE permits in lieu of City of Renton regulations. If not required by the associated USACE permits, the applicant shall comply with the maintenance and monitoring requirements for mitigation plans as outlined in RMC 4-3-050.L. b. Burden On Applicant City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 21 of 40 SR_HEX Broodstock_211101 ✓ See FOF 20.b.1.a above for additional analysis. Applicants for permits have the burden of providing that the proposed development is consistent with the criteria set forth in the Shoreline Master Program and the Shoreline Management Act, including demonstrating all reasonable efforts have been taken to provide sufficient mitigation such that the activity does not result in net loss of ecological functions. Staff Comment: The applicant submitted a Critical Areas Report prepared by Confluence Environmental Company and dated July 2020 (Exhibit 6). The Critical Areas Report identified both temporary and permanent impacts to the shoreline and uplands area as a result of the project. The report conduces that the proposed on-site mitigation would provide greater ecological benefit to the Cedar River relative to the minor loss of function due to the project impacts and therefore would result in no net loss of ecological function. See FOF 20.b.1.a above for additional analysis. c. Critical Areas within Shoreline Jurisdiction Compliant if Condition of Approval is met Unless otherwise stated, no development shall be constructed, located, extended, modified, converted, or altered, or land divided without full compliance with the provision adopted by reference and the Shoreline Master Program. Staff Comment: Critical areas on the site include sensitive slopes, steep slopes, a habitat conservation area, a high seismic hazard area, the wellhead protection area zone 1, and a flood hazard area. Flood Hazard Areas - Portions of the parcel to the south and parcel to the north of the Cedar River are within the 100-year floodplain. The regulatory floodway of the Cedar River also overlaps with portions of parcels 1723059014 (south bank) and 1723059013 (north bank). As an in-water feature, the BCF occurs in the preliminary floodway of the Cedar River. Per COR Maps, approximately 70 feet of the riparian area on the south bank and 30 feet on the north bank also occur within the preliminary floodway, while the upper 30 to 40 feet of the riparian area on the south bank and approximately 60 feet on the north bank falls within the 100-year floodplain. The upper portion of the south bank is designated Zone X, which refers to those areas with a 0.2% annual chance flood, 1% annual chance flood with average depths of less than 1 foot within a drainage area of less than 1 square mile, and those areas protected from the 1% annual chance flood by levees. The upper portion of the north bank is designated as Zone AE, meaning base flood elevations have been determined, which refers to the water surface elevation of the 1% annual chance flood. A no-rise condition analysis was conducted to ensure that the placement of the BCF permanent weir would not cause an increase in flood levels within the Cedar River floodplain during the occurrence of the base (100-year) flood discharge (Exhibit 9). A Hydrologic Engineering Center River Analysis System (HEC-RAS) provided to McMillen Jacobs by the City of Renton was modified to include the BCF permanent weir, and determined that the BCF permanent weir would have a no-rise effect on the 1% annual chance flood or base flood elevation, if the weir elevation is at or below elevation 29.6 feet. In addition, the BCF permanent weir does not affect the floodway widths for the with floodway 1% annual chance flood water surface elevations. In order to ensure the elevation of the weir at project completion does not exceed the maximum elevation permitted under the submitted no-net rise certificate, staff recommends, as a condition of approval, the applicant shall provide a final elevation survey prior to close out of the civil construction permit documenting compliance 29.6-foot maximum elevation identified in the No-Rise Study (Exhibit 9). Alternatively, if the proposed elevation of the weir changes prior to City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 22 of 40 SR_HEX Broodstock_211101 construction, the applicant may submit an amended No-Rise Study documenting compliance no-rise requirement in the floodway, to be reviewed and approved by the Current Planning Project Manager prior to approval of the Civil Construction Permit. Steep Slopes - The parcel to the south of the Cedar River is mapped with protected slopes (greater than 40 percent) and sensitive slopes (greater than 25 percent but less than 40 percent). The parcel to the north is mapped with sensitive slopes. All work proposed would occur outside of the steep slopes area. Seismic Hazard Areas - The entire project site is mapped within an area considered as a high seismic hazard and as such, is prone to structure failures as a result of liquefaction during a seismic event. As such, the applicant submitted a draft geotechnical report with the land use submittal. The geotechnical report would be reviewed at the time of civil construction permit application. Habitat Conservation Area - The Cedar River is also regulated as a Habitat Conservation Area (HCA). HCAs include habitats that have a primary association with the documented presence of non-salmonid or salmonid species proposed or listed by the Federal government or State of Washington as endangered, threatened, sensitive, and/or of local importance, per RMC 4-3-050. Because the Cedar River contains Puget Sound Chinook salmon and Puget Sound steelhead, which are federally listed threatened species, the Cedar River constitutes an HCA regulated under RMC 4-3-050.G.6and a Class 1 Fish Habitat Conservation Area under RMC 4-3-090.D.2.c.ii. Because the Cedar River is shoreline of the state (Type S water), work within the river and the riparian corridor is regulated under Renton’s SMP (RMC 4-3-090) as opposed to typical stream development and mitigation standards under the critical areas regulations (RMC 4-3-050). Additionally, land adjacent to the Cedar River in the Natural or Urban Conservancy environment is considered a Class 1 Fish Habitat Conservation Area subject to the provisions of the SMP (RMC 4-3-090.D). Requirements for development in HCA related to the proposed BCF include requiring that shoreline use and development be carried out in a manner that prevents or mitigates adverse impacts to ensure no net loss of ecological functions and processes, requiring that project-specific and cumulative impacts be considered and mitigated on- or off-site, and encouraging flexibility in the administration of the ecological protection provisions of the Shoreline Master Program. The applicant has proposed a robust compensatory mitigation plan that proposes on-site mitigation designed to optimize gain of ecological function for Chinook salmon, the most sensitive resource in the ecological system at the site. See 20.B.1.a above for no net-loss analysis and mitigation discussion. Wellhead Protection Areas - The entire project site is located within a wellhead protection zone, zone 1. The BCF occurs within the downtown WPA, known as Zone 1, which encompasses much of downtown Renton, the Cedar River, and associated riparian areas through Riverview Park (City of Renton 2020). The proposed use, as well as the activities to occur as a result of construction, are not prohibited in the WPA. However, due to the scope of the project and proposed excavation, the applicant must address and comply with RMC 4-4-030(C)(8) Construction Activity Standards – Aquifer Protection Area (APA) Zones 1 and 2 at the time of civil construction permit submittal (Exhibit 10). d. Development Standards for Aquatic Habitat 2. View Obstruction and Visual Quality City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 23 of 40 SR_HEX Broodstock_211101 ✓ View Corridors Required: Where commercial, industrial, multiple use, multi-family and/or multi-lot developments are proposed, primary structures shall provide for view corridors between buildings where views of the shoreline are available from public right-of-way or trails. Staff Comment: No buildings are proposed as part of the project and therefore no views from public rights-of-way or trails would be impacted by the proposed addition. N/A Minimum Setbacks for Commercial Development Adjacent to Residential or Park Uses: All new or expanded commercial development adjacent to residential use and public parks shall provide fifteen feet (15') setbacks from adjacent properties to attenuate proximity impacts such as noise, light and glare, and may address scale and aesthetic impacts. Fencing or landscape areas may be required to provide a visual screen. ✓ Lighting Requirements: Display and other exterior lighting shall be designed and operated so as to prevent glare, to avoid illuminating nearby properties used for noncommercial purposes, and to prevent hazards for public traffic. Methods of controlling spillover light include, but are not limited to, limits on the height of light structure, limits on light levels of fixtures, light shields, and screening. Staff Comment: The proposed project includes installation of one light pole. The light would be utilized only during emergencies and to improve safety during low light conditions, if needed. Given the limited anticipated use for this light and existing lights on site, no new or adverse light and glare impacts are anticipated. N/A Reflected Lights to Be Limited: Building surfaces on or adjacent to the water shall employ materials that limit reflected light. Staff Comment: No buildings are proposed as part of the project. N/A Integration and Screening of Mechanical Equipment: Building mechanical equipment shall be incorporated into building architectural features, such as pitched roofs, to the maximum extent feasible. Where mechanical equipment cannot be incorporated into architectural features, a visual screen shall be provided consistent with building exterior materials that obstructs views of such equipment. Staff Comment: No new mechanical equipment is proposed. If mechanical equipment is added to the proposal, compliance with the screening requirements would be verified at the time of formal civil construction or building permit application review. ✓ Visual Prominence of Freestanding Structures to Be Minimized: Facilities not incorporated into buildings including fences, piers, poles, wires, lights, and other freestanding structures shall be designed to minimize visual prominence. Staff Comment: The applicant has proposed one, freestanding light pole with a maximum height of fourteen (14’) feet, to be located at the top of the boat ramp. No existing structures are available for the light to be incorporated, but the light is the smallest possible height to provide effective lighting during evening maintenance or operations. N/A Maximum Stair and Walkway Width: Stairs and walkways located within shoreline vegetated buffers shall not exceed four feet (4') in width; provided, that where ADA requirements apply, such facilities may be increased to six feet (6') in width. Stairways shall conform to the existing topography to the extent feasible. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 24 of 40 SR_HEX Broodstock_211101 3. Community Disturbances: ✓ Noise, odors, night lighting, water and land traffic, and other structures and activities shall be considered in the design plans and their impacts avoided or mitigated. Staff Comment: The Cedar River Trail parking lot would be temporarily closed during both phases of construction. In Phase 2, access to the Park via Houser Way/Cedar River Park Drive would be closed. The larger Cedar River Trail and the Park will remain open forrecreation during construction, with detours or fencing around the active construction areas to ensure public safety.A project specific TCP will be implemented by the contractor to minimize impacts to recreational resources, provide standardized notifications of closure and access routes. Impact control measures within the TCP include but are not limited to placement of “Road Closed” barriers in locations where vehicle access is restricted, installation of pedestrian friendly detour signs that demarcate the temporary pathway of the rerouted Cedar River Trail, and coordination with the City to ensure that construction access/traffic will not present significant impacts to users of the Park. Once completed, the project would collect migrating sockeye salmon as part of the Hatchery Program. Noise, odors, night lighting, water and land traffic, and other potential community disturbances would not change as a result of the proposed project, which would provide an improved design to an existing facility. This existing and continued land use would not result in significant adverse noise, odor, lighting, or land traffic impacts. The BCF is installed after Labor Day each year, following peak use of the Cedar River from recreational users. Signage would be posted to warn in-water recreationalists of the obstruction and its use of electric actuators. Recreational users would also be alerted by signage upstream, which directs them to exit the river and walk around the BCF. Additional signage would be installed at the boat ramp to communicate that boat launching cannot occur when the weir and trap are in place. These restrictions would result in a slight interruption to watercraft travel in this area during non-peak recreation seasons. Impacts to watercraft traffic would be minimized through annual removal of overwater components of the replacement BCF at the end of the season each year, in December. At that time, the pickets would be laid onto the concrete sill and removed before early July, when peak season use of the river begins again. 4. Public Access Physical or visual access to shorelines shall be incorporated in all new development when the development would either generate a demand for one or more forms of such access, would impair existing legal access opportunities or rights, or is required to meet the specific policies and regulations of the Shoreline Master Program. ✓ Cedar River Reach C: Public/community access along the waterfront should be provided as private lands on the north side of the river redevelop, considered along with the goal of restoration of ecological functions. Public or community access shall be provided when residential development occurs consistent with standards of the Shoreline Master Program. Staff Comment: The Shoreline Master Program and the Renton Comprehensive Plan contain policies that encourage the provision of public access on all shorelines, especially if new development is proposed on a property. While public access may be temporarily impacted for a small portion of shoreline during construction of the facility, after City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 25 of 40 SR_HEX Broodstock_211101 completion of the project, the public would continue to have access the shoreline on both sides of the Cedar River adjacent to the project. 5. Archaeological, Historical, and Cultural Resources: ✓ Detailed Cultural Assessments May Be Required: The City will work with tribal, State, Federal, and other local governments as appropriate to identify significant local historical, cultural, and archaeological sites in observance of applicable State and Federal laws protecting such information from general public disclosure. Detailed cultural assessments may be required in areas with undocumented resources based on the probability of the presence of cultural resources. Staff Comment: The project proposal and notice of application were provided to reviewing agencies by the SEPA Lead Agency, Seattle Public Utility (applicant), including the State Department of Archaeology & Historic Preservation (DAHP) as part of the SEPA review process. An archaeological survey was conducted within the proposed project area prior to construction of the existing BCF, boat ramp, and access driveway. The associated Cultural Resources Assessment describes that the proposed project area contains historic fill, and the upland slopes have been altered through active river deposition and erosion of the floodplain; therefore, it is unlikely that ground-disturbing work would encounter intact deposits of significant prehistoric or cultural material. For these reasons, no further archaeological work was recommended. The only recommendation was to ensure that if cultural material was inadvertently discovered during construction, work should be suspended in the proposed project location. Consistent with the 2008 construction of the existing facilities, an Inadvertent Discovery Plan will be prepared prior to construction, and approved by SPU’s cultural resources coordinator. According to the applicant, a copy will be maintained on site throughout the duration of work. ✓ Coordination Encouraged: Owners of property containing identified or probable historical, cultural, or archaeological sites are encouraged to coordinate well in advance of application for development to assure that appropriate agencies such as the Washington State Department of Archaeology and Historic Preservation, affected tribes, and historic preservation groups have ample time to assess the site and identify the potential for cultural resources. Staff Comment: The Muckleshoot Indian Tribe is a member of the Adaptive Management Work Group for the LMA and has provided input and consultation throughout the design process for this proposed project. Also, see comment above. ✓ Detailed Cultural Assessments Required: Upon receipt of application for a development in an area of known or probable cultural resources, the City shall require a site assessment by a qualified professional archaeologist or historic preservation professional and ensure review by qualified parties including the Washington State Department of Archaeology and Historic Preservation, affected tribes, and historic preservation groups. Staff Comment: See comment above. Work to Stop Upon Discovery: If historical, cultural, or archaeological sites or artifacts are discovered in the process of development, work on that portion of the site shall be City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 26 of 40 SR_HEX Broodstock_211101 ✓ stopped immediately, the site secured, and the find reported as soon as possible to the Administrator of the Department of Community and Economic Development or designee. Upon notification of such find, the property owner shall notify the Washington State Department of Archaeology and Historic Preservation and affected tribes. The Administrator of the Department of Community and Economic Development or designee shall provide for a site investigation by a qualified professional and may provide for avoidance, or conservation of the resources, in coordination with appropriate agencies. Staff Comment: See comment above. ✓ Access for Educational Purposes Encouraged: Land owners are encouraged to provide access to qualified professionals and the general public if appropriate for the purpose of public education related to a cultural resource identified on a property. Staff Comment: See comment above. 6. Building and Development Location – Shoreline Orientation Shoreline developments shall locate the water-dependent, water-related, and water-enjoyment portions of their developments along the shoreline. Development and use shall be designed in a manner that directs land alteration to the least sensitive portions of the site to maximize vegetation conservation; minimize impervious surfaces and runoff; protect riparian, nearshore and wetland habitats; protect wildlife and habitats; protect archaeological, historic and cultural resources; and preserve aesthetic values. ✓ Location of Development: Development and use shall be designed in a manner that directs land alteration to the least sensitive portions of the site. Staff Comment: The replacement BCF, boat ramp, access road, and ancillary components are water dependent; minor project components (e.g., the light pole and Grasscrete-style turnaround) have been located as far from the Cedar River as feasible, yet within a distance from the Cedar River that would allow them to retain their function. While disturbance to the existing shoreline vegetation would occur, vegetation removal would be conducted in an area subject to past disturbance to the maximum extent practicable, and the addition of new impervious surfaces has been kept to a minimum by incorporating Grasscrete-style surfaces where feasible. A portion of the existing impervious surfaces would also be removed, including 653 SF of existing concrete boat ramp; this area would be restored with native vegetation once the concrete is removed. There are no documented archeological, historical, or cultural resources at the project site. ✓ Minimization of Site Alteration: Development shall minimize site alteration in sites with substantial unaltered natural features by applying the following criteria: (a) Vehicle and pedestrian circulation systems shall be designed to limit clearing, grading, and alteration of topography and natural features. (b) Impervious surfacing for parking lot/space areas shall be limited through the use of under-building parking or permeable surfaces where feasible. (c) Utilities shall share roadway and driveway corridors and rights-of-way wherever feasible. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 27 of 40 SR_HEX Broodstock_211101 (d) Development shall be located and designed to avoid the need for structural shoreline stabilization over the life of the development. Exceptions may be made for the limited instances where stabilization is necessary to protect allowed uses, particularly water- dependent uses, where no alternative locations are available and no net loss of ecological functions will result. Staff Comment: The proposed project would require an approximately 3-foot widening of the existing access road that leads to the boat ramp. A Grasscrete-style turnaround would be constructed to facilitate movement of the crane/equipment that is needed to install and remove components of the replacement BCF each year. These improvements would be to the existing access road and boat ramp and are not proposed as a separate or new facility. Improving the existing facility minimizes impacts to the shoreline ecology/topography. Electrical conduit would be installed within the footprint of the access road and reconfigured boat ramp. No parking is proposed. N/A Location for Accessory Development: Accessory development or use that does not require a shoreline location shall be located outside of shoreline jurisdiction unless such development is required to serve approved water-oriented uses and/or developments or unless otherwise allowed in a High Intensity designation. When sited within shoreline jurisdiction, uses and/or developments such as parking, service buildings or areas, access roads, utilities, signs and storage of materials shall be located inland away from the land/water interface and landward of water-oriented developments and/or other approved uses unless a location closer to the water is reasonably necessary. ✓ Navigation and Recreation to Be Preserved: Shoreline uses shall not deprive other uses of reasonable access to navigable waters. Existing water-related recreation shall be preserved. Staff Comment: The proposed project would not establish a new in-water use at the project site; rather, the existing use would be replaced with improved facilities. The improvements are limited to a concrete sill installed in the riverbed and an expansion to the existing access driveway and boat ramp. Therefore, the navigation and recreational impacts associated with the existing BCF would apply to the replacement facility. The BCF would continue to be installed after Labor Day each year, following peak recreational use of the Cedar River. Signage would be posted to warn in-water recreationalists of the obstruction and its use of electric actuators. Recreational users would also be alerted by signage upstream, which directs them to exit the river and walk around the BCF. Impacts to navigation would be minimized through annual removal of over-water components of the replacement BCF at the end of the season each year, in December. At that time, the pickets would be laid onto the concrete sill and removed before early July, when peak season use of the river begins again. 7. Standards for Density, Setbacks, and Height Structure Setbacks and Buffers (From the OWMW) Cedar River Reach C Standard: Enhancement of native riparian vegetation shall be implemented as part of management of public parks. Full standard native vegetation buffers should be maintained on the public open space on the south side of the river, subject to existing trail corridors and other provisions for public access. Enhancement of native riparian vegetation within the standard or modified buffers shall be provided upon redevelopment of the north shore, except in areas where public/community access City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 28 of 40 SR_HEX Broodstock_211101 is provided. The vegetation conservation buffer may be designed to incorporate floodplain management features including floodplain compensatory storage. Structure Setbacks and Buffers (From the OWMW) Urban Conservancy Shoreline Environment High Intensity Shoreline Environment Aquatic Shoreline Environment Water Dependent Use 100 feet None None Vegetation Conservation Buffer 100 feet 100 feet None Coverage Standards Impervious Area within the Buffer/Setback 5% 5% None Impervious Area within 100 feet of OHWM - Maximum 10% 50% None Staff Comment: There is no development proposed on the north side of the Cedar River on parcel 1723059013, which is within the High Intensity Shoreline Environment. In addition, the type of development proposed within the Aquatic Shoreline Environment does not have dimensional standards attributed to it. Compliance with specific dimensional standards associated with development in the Urban Conservancy Shoreline Environment is demonstrated below. 100-foot structure setback: The replacement BCF is intrinsically dependent on its in-water location; all upland components within the Urban Conservancy Shoreline Environment would need to be located within the 100-foot structure setback to support the replacement BCF. No new structures are proposed within the setback, only improvements to the existing boat ramp and access road. A new light pole would also be installed to join the existing three light poles on site. Given that the primary water-dependent use would be inoperable without these ancillary upland components within the 100-foot structure setback, SPU is requesting that the City maintain its modification to the setback to allow continued use of these structures. 100-foot vegetation conservation buffer: The replacement BCF is water dependent and would require alteration to the 100-foot vegetation buffer extending from the OHWM of the Cedar River. According to RMC 4-3-090(F)(1)(d),the City can exclude the vegetation buffer requirement for water-dependent uses or public access, provided that the area excluded from the vegetation buffer requirement is the minimum needed to provide the water dependent use or public access. The applicant requests to exclude the BCF facilities from the vegetation buffer requirement. The proposed project would permanently remove approximately 1,627 SF of existing riparian vegetation to accommodate the widening of the access road (to support crane access for BCF installation/removal), reconfiguration of the existing boat ramp (also required for BCF installation/removal, and City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 29 of 40 SR_HEX Broodstock_211101 21. Shoreline Conditional Use Analysis: The applicant is requesting a Shoreline Conditional Use Permit in order to replace the existing broodstock collection facility (BCF) with a new BCF, classified as a natural resources extraction/recovery use, in the High Intensity Shoreline Environmental Designation, as well as to excavate and fill material both landward and waterward of the OHWM. A portion of the proposed project would would be open to public access), and other minor improvements such as installation of a light pole, which is necessary for operation of the BCF. All project elements proposed within the 100-foot vegetation buffer are water dependent, directly in support of a water- dependent use, and/or would constitute a public access improvement. N/A Building Height – Maximum: In water – 35 ft. Within 100 feet of OHWM – 35 ft. More than 100 feet from the OHWM – 35 ft. Height up to that established in chapter 4-2 RMC, Zoning Districts – Uses and Standards, may be allowed for non-water-dependent uses in the following reaches: Lake Washington Reaches C, H, I, and J; Cedar River Reaches A, B, and C; Black River Reach A; May Creek Reach B; and Springbrook Creek Reaches B, C, and D: For buildings landward of one hundred feet (100') from OHWM, the maximum building height shall be defined by a maximum allowable building height envelope that shall: i. Begin along a line laying parallel to and one hundred feet (100') from OHWM at a height of either thirty five feet (35') or one half (1/2) the maximum height allowed in the underlying zone, whichever is greater; and ii. Have an upward, landward transition at a slope of one vertical to one horizontal from the beginning height either (a) until the line at which the maximum height allowed in the underlying zoning in chapter 4-2 RMC is reached (from which line the height envelope shall extend landward at the maximum height allowed in the underlying zoning), or (b) to the end of shoreline jurisdiction, whichever comes first. Staff Comment: No buildings are proposed as part of the project. 8. Use Regulations: a. Fish and Wildlife Resource Enhancement Use: ✓ Only allowed if a water dependent use. Staff Comment: The proposed replacement BCF is classified as a Fish and Wildlife Resource Enhancement Use, which is permitted in the Urban Conservancy and Aquatic Shoreline Environments when water dependent. Within the High Intensity Shoreline Environment, allowed uses are defined by the underlying zoning regulations rather than the codified SMP that is implemented as an overlay. Within the High Intensity Shoreline Environment’s underlying COR zone, the most similar use type to a BCF is a Natural Resources Extraction/Recovery use (as determined by the City in 2008 as part of the permitting process for the existing BCF). This use is considered a Hearing Examiner Conditional Use. The SMP equivalent to this review type is a shoreline conditional use; Therefore, the proposed project be allowed with an approved Shoreline Conditional Use Permit (SCUP). See FOF 21 for the SCUP analysis. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 30 of 40 SR_HEX Broodstock_211101 occur in the High Intensity Shoreline Environment designation, where allowed uses in the High Intensity Shoreline Environment are based on the underlying zone. Natural resources extraction/recovery uses require an Hearing Examiner Conditional Use Permit, therefore the corresponding Shoreline Conditional Use Permit is also required. In addition, the applicant is proposing in-water excavation, fill, and dredging in order to construct the coffer-dam structure used to hold back water during construction of the sill and retaining wall. The area of excavation would be backfilled with concrete to construct the permanent components of the replacement BCF. The proposed work is not intended to reach a new grade in-water and therefore is not considered dredging. Excavation for the concrete sill would be completed using a hydraulic excavator. Approximately 610 CY of material excavated below OHWM would be permanently removed from the river channel and taken off site for disposal if it is not suitable for reuse onsite as backfill. Approximately 610 CY of fill is proposed consisting of the concrete sill, aggregates under the sill, and boulders installed both upstream and downstream of the BCF to prevent scour. In addition, minor landward excavation and fill is required to widen the access road by three (3’) feet, install the light pole, create the grasscrete pad adjacent to the boat ramp, and remove a portion of the boat ramp (Exhibit 3). The proposal is compliant with the following conditional use criteria, pursuant to RMC 4-9-030.D. Therefore, staff recommends approval of the requested Conditional Use Permit. Compliance Conditional Use Criteria and Analysis ✓ a. Consistency with Plans and Regulations: The proposed use is consistent with the policies of RCW 90.58.020 and the Shoreline Master Program Staff Comment: The applicant contends that the proposed project would improve an existing water-dependent use, which collects sockeye salmon to support the Hatchery Program and terms of the original Landsburg Mitigation Agreement (LMA) established in 2000 in order to mitigate the prevention of salmon entering Seattle’s Cedar River Municipal Watershed. Staff concurs that a water-dependent use supporting salmon populations and restoration within the Cedar River is consistent with the general intent and purpose of the Shoreline Management Program. See FOF 20: Shoreline Management Program for additional compliance analysis. ✓ b. Interference: The proposed use will not interfere with the normal public use of public shorelines Staff Comment: The applicant contends that the proposed project would not result in changes to the public’s access to the shoreline, which would remain unchanged after project completion. While operation of the BCF requires recreational users to temporarily exit the Cedar River channel for safety, the non-permanent BCF components would continue to be removed after the collection season in December. According to the applicant, the picket panels would be removed annually before peak season use of the river and would be installed after Labor Day in September. The applicant contends that the timing of the annual installation and removal minimizes impacts to the public’s physical use of the river channel. Furthermore, the boat ramp provides public access to the shoreline when the BCF is not in operation. Staff concurs with the applicant that regular operation of the BCF would not result in interference with the normal use of public shorelines, as users will be able to access the northern shoreline at all times and southern shoreline at all times except for a few hours two (2) days a year during installation and removal of the overwater components. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 31 of 40 SR_HEX Broodstock_211101 ✓ c. Compatibility: The proposed use of the site and design of the project will be compatible with other authorized uses within the area and with uses planned for the area under the Comprehensive Plan and the Shoreline Master Program Staff Comment: The applicant contends that the proposed project would not establish a new use or development, but rather replace an existing facility that is seasonally part of the visual landscape and is visited by community members to observe natural salmonid migration and fish-handling. Seasonal operation of the existing BCF has not had significant impacts on other authorized uses in the area such as public recreation and therefore the replacement facility is also not anticipated to. According to the applicant, the facility would continue to add interest and educational opportunities related to the natural environment for both passive and active users of the site. If the land to the north of the site is ever redeveloped with commercial, office, and residential uses as is intended in the Commercial-Office-Residential (COR) Comprehensive Plan Land Use designation, the proposed BCF would be highly compatible with the future uses due the majority of operations occurring on the southern shore. The area south of the southern shoreline has a Comprehensive Plan Designation of Residential Low Density (LD) but is likely to remain a public recreation area due to the topography and other critical areas located on the site. Therefore, the proposed BCF would continue to be compatible with the established uses to the south of the site. Staff concurs that as a water-oriented use, the proposed BCF is compatible with the other authorized uses within the area and uses planned under the Comprehensive Plan and the Shoreline Master Program, which encourages water-oriented uses. ✓ d. Effects: The proposed use will cause no significant adverse effects to the shoreline environment in which it is to be located. Staff Comment: The applicant contends that the Critical Areas Report (Exhibit 6) and the Biological Assessment (Exhibit 5), both prepared by Confluence Environmental Company, include analysis and findings that the proposed natural resources extraction/recovery use would not cause significant adverse effects to the shoreline environment to which it is located, if the submitted mitigation plan (Exhibit 4) is implemented. Although both reports acknowledge the project would result in both temporary and permanent impacts to the shoreline environment, including approximately 5,362 sq. ft. of upland disturbance, on-site compensatory mitigation proposed by the applicant including re-establishment of native upland vegetation would result in no net loss of ecological function after project completion. Additional mitigation would include re-establishment of approximately 489 sq. ft. of riparian buffer and enhancement of approximately 6,680 sq. ft. of degraded riparian buffer. A large wood debris complex proposed along the existing gravel bar upstream from the proposed BCF but adjacent to the site is also proposed. Staff concurs with the applicant that the proposed uses, including the BCF and the excavation and fill, would not cause significant adverse effects to the shoreline environment if the mitigation plan is fully implemented, as confirmed by the environmental consultant. Compliant if Condition of Approval is met e. Public Interest: The public interest suffers no substantial detrimental effect. Staff Comment: The applicant contends that the proposed BCF is a passive use that would not generate significant adverse land use impacts or public access to the shoreline. According to the applicant, the BCF operation is a known attraction that brings users to the Cedar River Park and shoreline during the sockeye salmon upstream migration and provides educational and recreational opportunities to the public. As part of the original BCF land use approval (LUA08-018), the applicant installed interpretive City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 32 of 40 SR_HEX Broodstock_211101 signage on the north side of the riverbank on the City-owned site. The signs serve to help inform interested persons about salmon in the Cedar River and about the sockeye hatchery program in general. In addition, the applicant constructed a kiosk on the south side of the Cedar River adjacent to the Cedar River trail and boat ramp in order to provide additional information and public outreach. Due to age of the signs and proposed construction of a new facility that operates in a different manner than the original BC, the signage should be updated in order to ensure the project continues to promote public interest. Therefore, staff recommends, as a condition of approval, the applicant shall fabricate and install updated interpretative signage on both the north and south sides of the Cedar River near the project site. The applicant shall provide a signage plan to the Current Planning Project Manager for review and approval of the design, content, and location of the signage prior to Civil Construction Permit issuance. Staff concurs that the proposed use compliments the existing recreational uses in the area and as such, the public interest would not suffer substantial detrimental effect as a result of the project. i. Evaluation of Review Standards for Landfills and Excavations below the OHWM: The fill shall meet the landfill and excavation criteria in RMC 4-3-090.F.2. 1. The overall value to the public from the results of the fill or excavation site as opposed to the value of the shoreline in its existing state as well as evaluation of alternatives to fill that would achieve some or all of the objectives of the proposal. Staff Comment: The proposed excavation and fill is necessary in order to replace the existing BCF with a new BCF that would operate more efficiently and decrease the impact on public recreation in the river through the use of mechanical picket panels that can be lowered and raised at any time. Due to the need to construct the new BCF sill in a dry environment, no alternatives to creation of the coffer-dam and the related excavation are feasible. In addition, due to the need for a BCF that can operate at higher river flows, the installation of a new concrete sill, retaining wall, and boulders designed to prevent riverbed scour (all three elements classified as fill), alternatives to the 610 CY of fill are no feasible. The proposed mitigation, as discussed in other sections of this report, would offset all identified temporary and permanent impacts on the shoreline and therefore the projects value to the public is expected to exceed that of the existing BCF. Lastly, the preservation of salmon populations in the region is important for the health of the ecosystem and therefore benefits everyone. 2. Effects on ecological functions including, but not limited to, functions of the substrate of streams and lakes and effects on aquatic organisms, including the food chain, effects on vegetation functions, effects on local currents and erosion and deposition patterns, effects on surface and subsurface drainage, and effects on flood waters. Staff Comment: As noted in other sections of this report and discussed in-depth in the Critical Areas Report (Exhibit 6), the ecological function of the shoreline near the project site would not be degraded as a result of the project. The applicant has proposed a permanent aquatic mitigation component to offset the impacts of the excavation and fill, which include a large woody material complex along the OHWM on the gravel bar approximately 150 feet upstream of the proposed BCF location. The intent of the proposed wood material City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 33 of 40 SR_HEX Broodstock_211101 complex is to improve aquatic habitat complexity along the shallow channel margin. In addition, temporary BMPs to reduce the risk of increasing sediment levels in the river during excavation and filling are proposed including the installation of erosion and sediment control devices, the provision of regular discharge monitoring reports to the Department of Ecology, and the designation of one person as an erosion and spill lead during coffer-dam and sill construction. As discussed in additional detail under FOF 20.B.1.a, the Critical Areas Report concludes that the project would result in no net loss of ecological functions and value if all proposed mitigation is implemented. 3. Whether shoreline stabilization will be necessary to protect materials placed or removed and whether such stabilization meets the policies and standards of the Shoreline Master Program. Staff Comment: No shoreline stabilization is necessary for the proposed excavation and fill, except for minor reestablishment of vegetation. Boulders ranging in size from eight inches (8”) to sixteen inches (16”) would be placed both upstream and downstream of the concrete sill in order to prevent scour. In addition, areas near landward of the shoreline temporarily impacted by the construction would be seeded to stabilize disturbed areas that would remain unworked for more than two (2) days in the wet season or sevem (7 )days in the dry season to minimize the potential for erosion 4. Whether the landfill or excavation will adversely alter the normal flow of flood water, including obstructions of flood overflow channels or swales, after taking into account any compensating flood storage provided by the proposal. Staff Comment: As discussed under FOF 20.B.1.c, a no-rise condition analysis was conducted to ensure that the placement of the BCF permanent weir would not cause an increase in flood levels within the Cedar River floodplain during the occurrence of the base (100-year) flood discharge (Exhibit 9). The report concluded the BCF permanent weir would have a no-rise effect on the 1% annual chance flood or base flood elevation and would not impact the flow of flood water during a flood event. In addition, the area to be excavated would be backfilled with concrete in order to construct the permeant components of the replacement BCF and therefore would not adversely alter the normal flow of flood water. 5. Whether public or tribal rights to the use and enjoyment of the shoreline and its resources and amenities are impaired. Staff Comment: The proposed project would not result in changes to the public’s access to the shoreline near the project site, which would remain unchanged as after project completion. While operation of the BCF requires recreational users to temporarily exit the Cedar River channel for safety, the non-permanent BCF components would continue to be removed after the collection season, in December, and reinstalled in early September. Therefore, the public right to the use and enjoyment of the shoreline and its resources and amenities would not be impaired as a result of the project. According to the applicant, the Muckleshoot Indian Tribe is supportive of the proposed project and the benefit it will provide for salmon recovery efforts. The tribe is a member of the Adaptive Management Work Group for the LMA and City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 34 of 40 SR_HEX Broodstock_211101 has provided input and consultation throughout the design process for this proposed project. Staff did not receive any comments with regards to the proposed Shoreline permits from the Muckleshoot’s or any other tribe. Compliant if Condition of Approval is met j. Evaluation of Review Standards for Dredging: Dredging is permitted for development of approved water-dependent uses provided there are no feasible alternatives. If the associated land use decision is approved, the BCF would be classified as approved water-dependent use. Due to the need to collect salmonids in the Cedar River per the LMA, necessitating the construction of a replacement BCF and the associated concrete sill, no feasible alternative existed. i. New development, including the development of associate piers and docks, should be sited and designed to avoid or, if that is not possible, to minimize the need for new and maintenance dredging. Where alternatives such as the utilization of shallow access to mooring buoys is feasible, such measures shall be used. ii. All proposed dredging operations shall be designed by an appropriate State-licensed professional engineer. A stamped engineering report and an assessment of potential impacts on ecological functions shall be prepared by qualified consultants and shall be submitted to the Renton Planning Division as part of the application for a shoreline permit. iii. The responsibility rests solely with the applicant to demonstrate the necessity of the proposed dredging operation. iv. The responsibility rests solely with the applicant to demonstrate that: (a) There will be no net loss of ecological functions including but not limited to adverse effect on aquatic species including fish migration. (b) There will be no adverse impact on recreational areas or public recreation enjoyment of the water. v. Adjacent Bank Protection: (a) When dredging bottom material of a body of water, the banks shall not be disturbed unless absolutely necessary. The responsibility rests with the applicant to propose and carry out practices to protect the banks. (b) If it is absolutely necessary to disturb the adjacent banks for access to the dredging area, the responsibility rests with the applicant to propose and carry out a method of restoration of the disturbed area to a condition minimizing erosion and siltation.

Avoidance of Adverse Effects: The responsibility rests with the applicant to demonstrate the proposed dredging will avoid conditions that may adversely affect adjacent properties including: (a) Creating a nuisance to the public or nearby activity. (b) Damaging property in or near the area. (c) Causing substantial adverse effect to plant, animal, aquatic or human life in or near the area. (d) Endangering public safety in or near the area. vii. The applicant shall demonstrate control of contamination and pollution to water, air, and ground through specific operation and mitigation plans. viii. Disposal of Dredge Material: The applicant shall demonstrate that the disposal of dredged material will not result in net loss of ecological functions or adverse impacts to properties adjacent to the disposal site. (a) The applicant shall provide plans for the location and method of disposing of all dredged material. (b) Dredged material shall not be deposited in a lake, stream, or marine water except if approved as habitat enhancement or other beneficial environmental mitigation as part of ecological restoration, a contamination remediation project approved by appropriate State and/or Federal agencies, or is approved in accordance with the Puget Sound Dredged Disposal Analysis evaluation procedures for managing in-water- disposal of dredged material by applicable agencies, which may include the U.S. Army Corps of Engineers pursuant to Section 10 (Rivers and Harbors Act) and Section 404 (Clean Water Act) permits, and Washington State Department of Fish and Wildlife hydraulic project approval. (c) In no instance shall dredged material be stockpiled in a shoreland area that would result in the clearing of native vegetation. Temporary stockpiling of dredged material is limited to one hundred eighty (180) days. (d) If the dredged material is contaminant or pollutant in nature, the applicant shall propose and carry out a method of disposal that complies with all regulatory requirements. City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 36 of 40 SR_HEX Broodstock_211101 (e) Permanent land disposal shall demonstrate that: (1) Shoreline ecological functions will be preserved, including protection of surface water and groundwater. (2) Erosion, sedimentation, flood waters or runoff will not increase adverse impacts to shoreline ecological functions or property. (3) Sites will be adequately screened from view of local residents or passersby on public rights-of-way. (4) The site is not located within a channel migration zone. Staff Comment: Although technically meeting the definition of dredging due the work including removal of material the OHWM, the sediment-disturbing work proposed as part of the proposed project is best characterized as in-water excavation. This would occur within the cofferdam structure and the area would be backfilled with concrete to construct the permanent components of the replacement BCF. The work is not to reach a new grade in-water or alter water flow, which is typically the intent of dredging. The dredging is required for the water-dependent project components located below the OHWM, including the permanent concrete sill within the Cedar River channel, the concrete retaining wall along the base and upstream of the boat ramp, and majority of the grasscrete pad. These project components together comprise a majority of the permanent elements of the replacement BCF. The no-net-loss criteria have been addressed above under FOF 20.B.1.a. Regarding public safety in the water during construction, in-water activities would occur behind a cofferdam system that extends to mid-channel only. The applicant contends that containing construction would maintain a safe environment for the public who may be in the general project vicinity. Construction-related disruptions to the public’s normal use of the shoreline would be limited to a maximum of 6 total months over 2 years. During the construction period, signage would be posted to notify recreational users of project construction, directing them to exit the river and walk around the work area, consistent with the direction provided when the BCF is installed each year. Approximately half the width of the river channel in the project site would be open during construction, although recreation in this area is not advised due to public safety concerns. Regarding disturbance to the shoreline, the bank on the north side of the Cedar River (which is composed of a rock retaining wall along the edge of the Park) would not be disturbed. Disturbance of this bank would be engineered to minimize scour and protect the boat ramp that facilities operation of the BCF and also provides public access to the shoreline. Approximately 610 CY of sediment would be removed as a result of the dredging in order to facilitate installation of permanent components of the BCF. Therefore as discussed above, as well as elsewhere throughout the report, the proposed dredging complies with the requirements in the SMP. However, in order to ensure the dredged material is disposed of property, staff recommends, as a condition of approval, the applicant shall provide a materials disposal plan for the dredging that includes information regarding the location and method of disposing of all dredged material.

Shoreline Variance Analysis: The applicant is requesting a Shoreline Variance from RMC 4-3-050D.3, Tree Retention and Land Clearing Requirements in order to remove one tree within the Cedar River Reach C Regulated shoreline area, a Shoreline of the State. Per RMC 4-4-130D.3, no tree removal or land clearing is permitted in critical areas or buffers associated with shorelines of the state. In addition, per RMC 4-3- 050C.3, the removal of non-dangerous trees is not an exempt activity and therefore requires a variance. Per RMC 4-3-090.D.2.c, variances to critical areas regulations shall processed through a shoreline variance when located in the shoreline area. Specifically, the applicant is proposing to remove one 36-inch Black cottonwood tree located approximately 10 feet from the Cedar River OHWM, as well as approximately 92 sq. ft. of vegetation. The applicant is proposing removal of the tree and adjacent vegetation in order to install grasscrete pavers that would extend the boat ramp area and provide enough room for the stabilizers on the crane used during seasonal installation and removal of the BCF over-water equipment. Per RMC 4- 3-090.D.2.c, variances to critical areas regulations shall processed through a shoreline variance when located in the shoreline area. The proposal is compliant with the following shoreline variance criteria, pursuant to RMC 4-9-190I.4. Therefore, staff recommends approval of the requested variance. The plan shall be submitted to the Current Planning Project Manager for review and approval prior to civil construction permit issuance. Compliance Variance Criteria and Analysis ✓ a. That the strict application of the bulk, dimensional or performance standards set forth in the applicable master program precludes, or significantly interferes with, reasonable use of the property. Staff Comment: According to RMC 4-4-130(D)(3), all tree removal or land clearing is prohibited within Shorelines of the State, unless a variance is granted. In addition, removal of a non-dangerous tree is not an exempt activity per RMC 4-3-050 Critical Areas Regulations. The entire project site is located within 200 feet of the Cedar River and is, therefore, entirely within a Shoreline of the State. According to the applicant, the primary driver for the variance is the need for the proposed replacement BCF to be installed upriver from the existing facility so as to allow collection to continue uninterrupted, as required by the LMA. The applicant contends that the variance is necessary in order to shift the existing boat ramp to the east (i.e. upriver), which would include the installation of grasscrete pavers in the place of the existing vegetation and Black cottonwood tree. The grasscrete pavers will provide a flat, hard surface for the installation crane’s stabilizer arms during installation and removal of the over-water BCF components. The applicant contends that given the vegetated/wooded condition of the site, strict application of the code would preclude the ability to relocate the boat ramp and therefore would be interfere with ability for the BCF to operate on the site. Staff concurs with the applicant’s justification and finds that strict application of the Tree Retention and Land Clearing Requirements in RMC 4-4-130.D.3 would interfere with reasonable and intended use of the property. ✓ b. That the hardship is specifically related to the property, and is the result of unique conditions such as irregular lot shape, size, or natural features and the application of the master program, and not, for example, from deed restrictions or the applicant's own actions. Staff Comment: The entire project site is located within 200 feet of the Cedar River and is, therefore, entirely within a Shoreline of the State. See analysis above under FOF 22.a City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 38 of 40 SR_HEX Broodstock_211101 ✓ c. That the design of the project is compatible with other authorized uses within the area and with uses planned for the area under the comprehensive plan and shoreline master program and will not cause adverse impacts to the shoreline environment. Staff Comment: The applicant contends that the proposed project would not establish a new use or development, but rather replace an existing facility that is seasonally part of the visual landscape and is visited by community members to observe natural salmonid migration and fish-handling. Seasonal operation of the existing BCF has not had significant impacts on other authorized uses in the area such as public recreation and therefore the replacement facility is also not anticipated to. According to the applicant, the facility would continue to add interest and educational opportunities related to the natural environment for both passive and active users of the site. The area south of the southern shoreline near the location of the proposed work requested as part of the variance has a Comprehensive Plan Designation of Residential Low Density (LD), but is likely to remain a public recreation area due to the topography and other critical areas located on the site. Staff concurs with the applicant’s justification and finds that the proposed variance would continue to be compatible with the established uses on the south side of the river, especially the public boat ramp. In addition, the granting of the variance which would allow the expansion of the boat ramp is compatible with the other authorized uses within the area and uses planned under the Comprehensive Plan and the Shoreline Master Program, which encourages water-oriented uses. ✓ d. That the variance will not constitute a grant of special privilege not enjoyed by the other properties in the area. Staff Comment: The applicant contends that due to the extremely unique nature of the use, a salmon collection facility, the proposed variance would not constitute a grant of special privilege. Since the characteristics of the use and related variance are so specific to the proposed BCF, it is difficult to view the variance through the lens of providing a special privilege. Staff concurs with the applicant and finds that the due to the extremely specific requirements and characteristics of the BCF when compared to other uses along the Cedar River, approval of the variance would not constitute a grant of special privilege. ✓ e. That the variance requested is the minimum necessary to afford relief. Staff Comment: The applicant contends that the proposed vegetation and tree removal is the minimum amount necessary to accommodate the proposed improvements and that the limited scale of proposed vegetation/tree disturbance would ensure that there are no detrimental impacts to the public’s welfare of adjacent shoreline properties. In addition, the applicant would be replacing the vegetation with grasscrete pavers which not classified as vegetation, provide a close approximate to natural vegetation and the associated drainage and visual characteristics. Staff concurs with the applicant and finds that the variance requested is the minimum necessary to afford relief for the associated BCF project. ✓ f. That the public interest will suffer no substantial detrimental effect. Staff Comment: The applicant contends that since tree removal would be mitigated on site at a ratio of 2:1, and areas of temporary vegetation removal would be replanted City of Renton Department of Community & Economic Development SPU Broodstock Collection Facility Replacement Staff Report to the Hearing Examiner LUA21-000259, SA-A, CU-A, SSDP, VAR, CU-S Report of November 9, 2021 Page 39 of 40 SR_HEX Broodstock_211101 23. Critical Areas: Critical areas on the site include sensitive slopes, steep slopes, a habitat conservation area, a high seismic hazard area, the wellhead protection area zone 1, and a flood hazard area. The Cedar River is a Type S waterbody, or Shoreline of the State. Per RMC 4-3-090, Type S waterbodies are regulated under Shoreline Management Program regulations in RMC 4-3-090 and not under RMC Section 4-3-050. Included within shoreline jurisdiction are floodways and all lands within 200 feet of the OHWM (RMC 4-3-090), which include the entire project limits and study area. All in-water and upland components of the project would occur within shoreline jurisdiction and therefore all analysis related to critical areas can be found under FOF 20.B.1.c, Shoreline Master Program Regulations: Critical Areas.

There are adequate public services and facilities to accommodate the proposed Broodstock Collection Facility, see FOF 18. 10. Key features, which are integral to this project, include the use of grasscrete for the boat ramp extension, approximately 10,900 sq. ft. of combined aquatic and riparian mitigation, and the vegetation management proposal consisting of invasive species installation removal and native plant installation along the shoreline. Other key features include the use of BMPs to avoid sedimentation build-up in the river, limiting with native vegetation, the public interest will not suffer substantial detrimental effect as a result of the variance being granted. In addition, compensatory mitigation will be provided for additional permanent impacts to the riparian buffer to ensure no net loss of ecological function. As a whole, the public interest would be positively impacted by the variance as it allows for the construction of a wider, higher quality boat ramp that can be utilized by kayakers, canoers, and other recreationalists after project completion.
