The region is a hotspot of biodiversity and have been and continue to be home to communities of Coast Salish Peoples since time immemorial. Many people travel to western Washington to vacation and engage in outdoor activities in what they perceive to be a mix of wild setting and pastoral landscapes; however, Indigenous North Americans shaped the region's’ terrain through landscape management practices for thousands of years. Landscape Stewardship practices past and present of Coast Salish Peoples throughout the region often center on food and medicinal plants, game, waterfowl, shellfish, and various fish species. Such resources are not seen solely as consumable goods but rather as essential to Coast Salish values, beliefs, and lifeways. They are a vital component of spiritual, cultural, and community well-being as well as environmental health. Archaeological records reveal that at least 280 plants, birds, mammals, fish, reptiles, shellfish, and other marine life comprised Coast Salish cuisine. We recognize that this land acknowledgment is one small step toward true allyship. We are committed to uplifting the voices, experiences, and histories of the Indigenous People of this land and beyond. 1 Introduction This Monitoring and Inadvertent Discovery Plan (MIDP) was created for the City of Renton’s 600 SW 10th Parking Lot Improvement Project (Project No.: 2021- 08- 05764). Fullscope NW (FSNW) archaeologists, Jena Kalli, and Jeremy Ripin will conduct the monitoring. The MIDP outlines the protocols for protecting and reporting inadvertent discoveries of archaeological materials and/or the unanticipated encountering of human remains. Following the monitoring work, FSNW will complete a report that summarizes observations during construction. Proposed development includes construction of a truck parking lot with spaces for approximately 140 semi-trucks with trailers along with associated driving and turning lanes. The planned improvements will also include the installation of underground utilities, such as an underground detention vault and other stormwater and utility infrastructure. The Department of Archaeology and Historic Preservation (DAHP) reviewed the project and identified the area to be at very high risk of containing archaeological resources. Historic General Land Office (GLO) maps show the project is in close proximity to a historic bank of the White River. In addition, a geotechnical report (Pan Geo inc. 2021) indicates the original ground surface is located below historic fill layers, and will likely be impacted by the construction of the underground detention vault and other stormwater and utility infrastructure. Therefore, the DAHP recommended that a MIDP be developed and an archaeologist monitor activities that may encounter and disturb the original ground surface. Project Location The project is located at 600 Southwest 10th Avenue (TPN 2146000050), Renton, King County, Washington (Figure 1). The project area is a rectangular-shaped area, approximately 4.5 acres in size on the north side of an existing warehouse building, 2 and surrounded to the north, south, east, and west by one-story warehouse buildings (Figure 2). Activities that will be monitored are located along the west edge of the project area and focused on the construction of an underground detention vault and other stormwater and utility infrastructure, and are highlighted in the included design plan (Figure 3). Current Conditions The project area is vacant of structures and relatively flat with less than five feet of elevation change across the length of the site. The north half of is vegetated with a thin covering of grass, while the south portion of the site is surfaced with asphalt and gravel and is being used for outdoor storage. The perimeter of the site is vegetated with alder trees. A geotechnical report conducted to assess soil suitability for the project indicates the project area consists of three basic soil layers. A surficial layer of topsoil and sod approximately 6 inches think; a layer of poorly sorted fill approximately two to four feet thick; above a layer of well sorted silt interpreted to be a deposit of the White River down to approximately 10 feet below the surface (Pan Geo Inc. 2021).

Monitoring and Inadvertent Discovery Plan for Archaeological Resources or Human Skeletal Remains Monitoring Protocols FSNW shall provide a professional archaeologist to be on-site during all activities with the potential to encounter or cause ground disturbance of the historic sediments buried under layers of fill within the project area. The historic sediments are estimated to be from approximately 2 to 4 feet deep below the surface. Inadvertent Discovery Plan 1.If suspected archaeological materials are encountered, construction activities shall halt in the immediate vicinity (at least 10 meters) so that the archaeologist can examine the potential find; 2.If upon examination it is determined that there are archaeological materials, the archaeologist shall secure the area and make all efforts to protect the area from further construction work; 3.The DAHP, affected Tribes, project proponents, and other consulting parties shall be contacted expeditiously (see contact list); 4.The treatment of the archaeological resources shall be determined through coordination with these organizations at that time; and 5.If avoidance of the archaeological resources is not feasible under project constraints, work in that location shall cease; further consultation will be required and in accordance with regulations (RCW 27.44 and RCW 27.53), a permit will need to be obtained from the DAHP before work can proceed. 7 Collections Archaeological materials will not be collected during this project unless a collection plan is developed and agreed upon by all consulting parties and an DAHP permit includes such activity. Inadvertent Discovery of Human Skeletal Remains If suspected human remains are encountered, all work shall cease immediately. Some photographs of the find may be taken and sent to the State Physical Anthropologist or other appropriate individuals to help with identification to determine if the remains are human or faunal. Pursuant to RCW 68.60.055, if human remains are encountered, the monitor shall: 1.Immediately cease all activity that may cause further disturbance to the remains and make a reasonable effort to protect the area from further disturbance; 2.Notify law enforcement in the most expeditious manner possible; 3.Notify the DAHP, affected Tribes, project proponents, and other consulting parties in the most expeditious manner possible (contact list is available below); and 4.Further work shall not occur until all consulting parties are in concurrence that the project may proceed. 8 Contact List Name Organization Title Phone Sky McClave Kimely-Horn Project Manager/Engineer (206) 705 9767 Lance Wollwage DAHP State Archaeologist (360) 890-2616 Stephanie Jolivette DAHP Local Government Archaeologist (360) 628-2755 Guy Tasa DAHP State Physical Anthropologist (360) 790-1633 Jon Schuldt Renton Police Department Police Chief (425) 430-7500 Patti Cole-Tindall King County Sheriff’s Office Interim Sheriff (206) 296-3311 Alex Morganroth Renton Community & Economic Development Senior Planner (425) 430-7200 Richard Harruff, MD, PhD King County Medical Examiner Chief Medical Examiner (206) 731-3232, ext. 4 Laura Murphy Muckleshoot Indian Tribe Archaeologist (253) 876-3272 Richard Young Tulalip Tribes Cultural Resources 360-716-2652 Dennis Lewarch Suquamish Tribe Tribal Historic Preservation Officer (THPO) (360.394.8529 Rhonda Foster Squaxin Island Tribe THPO 360-432-3850 Steven Mullen- Moses Snoqualmie Tribe Director, Archaeology and Historic Preservation (425) 292-0249, ext. 2010 Kerry Lyste Stillaguamish Tribe of Indians THPO (360) 652-7362, ext. 226 Jeremy Ripin Fullscope NW Project Archaeologist (360) 298-8500 Jena Kalli Fullscope NW Project Archaeologist (360) 298-8500 9
