The lakeline system consists of a flush station, an 8-inch cast iron sewer pipe buried offshore in Lake Washington, a system of side sewer laterals connecting customers to the lakeline system, and the Lake Washington No. 2 lift station that pumps the flow to the King County regional system. The Kennydale lakeline system is aging and needs to be replaced to ensure long-term service and to protect Lake Washington. In 2016, the City of Renton (the City) hired a consultant team, led by Carollo Engineers, to evaluate the condition of the lakeline system in two phases. This project team developed alternatives to address operation, maintenance, and reliability. From 2016-2018, the City conducted an assessment of the Kennydale lakeline system, which included an attempt to clean and video inspect the entire lakeline system in 2018. Due to its location, varying water depth, and the original construction methods used, the City was only successful in cleaning and inspecting approximately 80% of the lakeline system. As part of the hydraulic assessment, it was concluded that the hydraulic capacity of the lakeline system is reduced, indicative of partial blockages in two general areas. These partial blockages are likely the result of solids settlement caused by velocities below those needed for self-cleaning, and settlement of the lakeline over time resulting in undulating slope. Current access from the shoreline for cleaning is limited, and settled solids cannot effectively be removed using the shore-based cleaning protocol. The City has come to the conclusion that a land-based grinder pump sewer system is needed based on results from the 2018 assessment, cleaning and maintenance attempts, participation in the in-water sewer workgroup, environmental and permitting considerations, and evaluation of numerous alternatives. Kennydale Lakeline Sewer System Replacement Project (the project) is being designed and permitted per applicable regulatory requirements. Once the replacement system is complete, the existing lakeline system will be decommissioned. Confirming the feasibility and designing the land-based grinder pump sewer system replacement requires geotechnical explorations and testing. Five borings are proposed along the shoreline (Figure 2). This document provides information for geotechnical exploration of the project site to design the lakeline system replacement.

The methods used to identify critical areas satisfy the information needs identified under Renton Municipal Code (RMC) 4-3-050B and RMC 4-3-090B. 2.1 Wetlands Based on global information system (GIS) data, no wetlands are within 300 feet of the lakeline system (King County 2024; Renton 2024; USFWS 2024; WDFW 2024a). 2.2 Streams and Lakes No streams are located within the lakeline system. However, May Creek is located just north of the Lake Washington #2 Lift Station. May Creek is a 7-mile long tributary to Lake Washington. It is classified as a Type S stream within the vicinity of the Lake Washington #2 Lift Station (DNR 2024). The creek originates in the steep forested slopes of Cougar and Squak Mountains and in the highlands of the Renton Plateau and discharges into Lake Washington just north of the Lake Washington #2 Lift Station. May Creek provides high quality tributary habitat to Lake Washington. However, use of May Creek by salmonids and other wildlife is declining due to habitat loss, erosion, sedimentation, and deteriorating water quality (King County and City of Renton 2001). Fall Chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), sockeye salmon (O. nerka), resident costal cutthroat (O. clarki), and steelhead (O. mykiss) are known to use May Creek (WDFW 2024b). Lake Washington provides habitat for a wide variety of fish life, including Endangered Species Act (ESA)-listed species Puget Sound Chinook salmon, Puget Sound steelhead, and Coastal- Puget Sound bull trout (Salvelinus malma), as well as other salmonids such as coho salmon, sockeye salmon, and resident costal cutthroat trout (WDFW 2024b, 2024a). A distinct population of sockeye salmon spawn on Lake Washington beaches. Spawning takes place in Lake Washington wherever suitable gravel beaches with upwelling are available (Gustafson et al. 1997; WDFW 2024c). A majority of the lakeline system has been mapped as sockeye spawning habitat based on suitable gravels and historical spawning activity (WDFW unknown date), but the geotechnical explorations will all be above the ordinary high water mark (OHWM) of Lake Washington and will not overlap with salmonid habitat. Water quality within Lake Washington along the areas that overlaps with the lakeline system is not on the Washington State Department of Ecology (Ecology) 303(d) list (Ecology 2024a). However, just offshore of Coleman Point, a portion of Lake Washington is classified as Category 1 for bacteria and total phosphorus and a Category 2 for 4,4’-DDD, 4,4’-DDE, methyl Docusign Envelope ID: 8E053BA1-DC98-4EA7-8828-AB440FD823C7 Kennydale Lakeline Sewer System Replacement Project: Project narrative – Geotechnical Explorations May 2024 Page 4 mercury, and polychlorinated biphenyls (PCBs) (Ecology 2024a). A Category 1 is designated when an area meets the standards for clean waters. Placement of a waterbody in Category 1 does not necessarily mean that a water body is free of all pollutants, just that it meets the standards for all the pollutants for which it was tested. A Category 2 is designated when an area is of concern. These areas have some evidence of water quality problems but not enough to require production of a water quality improvement project. Just north of lakeline system (north of May Creek), a portion of Lake Washington is classified as Category 2 for PCBs and as a Category 1 for bacteria and total phosphorus. The same area north of May Creek is on the 303(d) list for sediment because sediment bioassays, arsenic, high molecular weight polycyclic aromatic hydrocarbons (HPAHs), low molecular weight polycyclic aromatic hydrocarbons (LPAHs), and phenol failed to meet the standards. Category 5 is designated when polluted waters/sediments are present (i.e., on the 303(d) list). 2.3 Flood Hazard Areas Based Renton (2024) GIS data, no flood hazard areas are within 300 feet of the lakeline system. 2.4 Steep Slopes Slopes along the shoreline range from flat (less than 15% slope) to gently or moderately sloping (less than 40% slopes), with a majority of the shoreline having 15 to 25% slopes (Renton 2024). 2.5 Habitat Conservation Areas No wildlife habitat corridors or priority species sites were identified along the lakeline system (WDFW 2024a). 2.6 Shorelines The shoreline of Lake Washington is designated as a Shoreline of the State as defined by RMC 4-3-090B(1a). As such, the shoreline is defined as 200 feet landward of the OHWM of Lake Washington. The OHWM of Lake Washington is 18.6 feet elevation according to North American Vertical Datum of 1988 (NAVD 88). There is approximately 4,670 linear feet of shoreline along the lakeline system. The shoreline in this area is highly modified with approximately 4,370 linear feet of the shoreline heavily armored with riprap, gabion walls, or other vertical bulkheads. There are a few areas (approximately 300 linear feet in total) where bulkheads are absent and gravel dominated pocket beaches occur. There are also overwater structures are present throughout the shoreline along the lakeline system corridor (Ecology 2024b). Overwater structures consist primarily of docks associated with single-family residences. A log boom delineating the designated swimming area at Kennydale Beach Park is also present. Docusign Envelope ID: 8E053BA1-DC98-4EA7-8828-AB440FD823C7 Kennydale Lakeline Sewer System Replacement Project: Project narrative – Geotechnical Explorations May 2024 Page 5 Riparian vegetation along the lakeline system is primarily lawn and ornamental shrubs, with scatted trees. The riparian vegetation provides little shading over the nearshore waters. The exception to this are the riparian areas just north of the house at 3307 Lake Washington Boulevard and the shoreline associated with 3827 Lake Washington Boulevard. On these lots, there are existing mature trees and shrubs that extend over the nearshore water, providing shade, cover, and insect drop into the lake. Proposed geotechnical borings are located in upland areas either in the City ROW, King County ROW, or other public property (Table 1). All proposed geotechnical boring locations and access routes are located on asphalt or graveled surfaces and no vegetation overlaps with where the borings are proposed. Table 1.

There would be a total of 5 borings located along the shoreline (Figure 2). The equipment, work area, access considerations, and duration of drilling for each boring location is described below. The proposed borings avoid work below the OHWM of Lake Washington (i.e., no in-water work). Aside from overlapping with the shoreline zone, no other critical areas will be impacted during geotechnical explorations. All borings are proposed through asphalt or gravel and no vegetation will be disturbed. Proposed geotechnical borings will be advanced using a track-mounted Acker Recon drill rig and mud-rotary drilling methods to a depth of 15 feet to 25 feet below ground surface (Table 2). Soil samples will be obtained in conjunction with standard penetration tests at 2.5-foot intervals. Each boring will include an observation well for measuring groundwater depths. A vibrating wire piezometer will be installed at each boring location to monitor water levels continuously for the duration of the project. Table 2.

Most staging areas will be at the same location as the borings. Due to the location of nearby residences, B-1 will likely be staged from the B-2 location. The boring will require a work area that is approximately 20 feet wide by 50 feet long (~1,000 square feet). In addition to the work area for the boring, the following will be needed: ▪ Blocking to protect the curb during mobilization and to level the drill rig. ▪ Mats or plywood to protect the ground from rutting, ▪ Plastic sheeting beneath the mud tank to protect from mud leakage. ▪ Straw wattles around the mud tank to protect from mud leakage. ▪ Absorbent pads beneath the drill rig to protect from oil and hydraulic fluid leakage. ▪ Four (4) 50-gallon barrels to contain drill cuttings and drilling mud.

Docusign Envelope ID: 8E053BA1-DC98-4EA7-8828-AB440FD823C7 Kennydale Lakeline Sewer System Replacement Project: Project narrative – Geotechnical Explorations May 2024 Page 8 3.1 Geotech Best Management Practices Best management practices (BMPs) that will be implemented to protect critical areas and buffers include: ▪ Project staging and storage areas will be located in currently developed areas, such as City ROWs adjacent to each boring location. ▪ All equipment to be used for construction activities will be cleaned and inspected prior to arriving at the project site to ensure no potentially hazardous materials are exposed, no leaks are present, and the equipment is functioning properly. ▪ Construction equipment will be inspected daily to ensure there are no leaks of hydraulic fluids, fuel, lubricants, or other petroleum products. Absorbent pads will be placed beneath equipment to catch any leakage. Should a leak be detected on heavy equipment used for the project, the work will immediately cease and will not be used again until repaired. ▪ Construction equipment will not enter Lake Washington below the OHWM. ▪ The contractor will designate at least one employee as the erosion and spill control (ESC) lead. The ESC lead will be responsible for the installation and monitoring of erosion control measures and maintaining spill containment and control equipment. The ESC lead will also be responsible for ensuring compliance with all local, state, and federal erosion and sediment control requirements. ▪ Plastic sheeting and straw wattles will be utilized along the downslope edge of ground disturbing activities and around the mud tank to intercept sediment transported by water runoff prior to entering surface waters. ▪ All temporary erosion and sedimentation control measures will be inspected, maintained, and repaired for the duration of the field investigation program to ensure continued performance of their intended function. Straw wattles will be inspected immediately after each rainfall, and at least daily during prolonged rainfall. Sediment will be removed as it collects behind the straw wattles. ▪ Should any BMPs not function as intended, additional actions will be made to minimize erosion, maintain water quality, and achieve the intended environmental performance. ▪ Thinners and solvents will not be used to wash oil, grease, or similar substances from heavy machinery or machine parts. ▪ All fueling and maintenance of equipment will occur more than 300 feet from the nearest wetland, ditches, flowing or standing water unless it is within an existing parking lot. 3.2 Groundwater Monitoring Wells Five wells will be installed in the boring locations. Each well will have a vibrating wire piezometer installed to monitor water levels continuously for the project duration. During Docusign Envelope ID: 8E053BA1-DC98-4EA7-8828-AB440FD823C7 Kennydale Lakeline Sewer System Replacement Project: Project narrative – Geotechnical Explorations May 2024 Page 9 design, the wells will be accessed for monitoring once every 3 months (seasonally). The wells will be decommissioned by the contractor. The wells will be decommissioned in accordance with the requirements of Washington Administrative Code (WAC) 173-160 by backfilling with either bentonite chips or bentonite slurry. 3.3 Timing Geotechnical explorations will occur as soon as the permits are obtained. A King County Special Use Permit is concurrently under review. This work is anticipated to take approximately 2 days to complete.
