This project must comply with Section 106 of the National Historic Preservation Act (NHPA) and its implementing regulations (36 CFR 800). This document reports the results of the Cultural Resources Assessment. The results of previous field work suggest that there is potential for encountering intact historic or pre-contact archaeological resources in the project area. Stantec archaeologists conducted field work in the project area in response to the need for cultural compliance. Survey and testing was conducted on July 11 and 12, 2017. Field crew consisted of Justin Junge, MS (Stantec) and Nathan Jereb, BA (Stantec). Junge meets the Secretary of Interior Professional Qualifications Standards for Archaeology. No historic or pre-contact cultural material was identified within the project area. Previous manipulation of the landscape for the construction of the sewer lines in 1965 and erosional control and stream modification has disturbed or displaced any potential cultural material in the project area. Based on this information, no further archaeological work is required within the current project area. Should the project area be adjusted, specifically on the terraces above the current slope, then further testing is recommended.

Thunder Hills Creek is located in a steep, narrow ravine that is incised from stream flows. The Thunder Hills Sanitary Sewer Interceptor traverses along and crosses under Thunder Hills Creek within this ravine. A maintenance road and trails for access to the sewer main are also located along the creek alignment. The existing sewer main was originally constructed in 1965 and consists of 10-inch, 12-inch and 18-inch concrete, asbestos cement, and ductile iron pipe. In 2014 an inspection was conducted to determine the condition of the existing line. Grease buildup, pipe joints that had separated over time, broken lip sections, corrosion of cast iron fittings, concrete lining spalling, heavy scale deposits, minor root intrusion, and a sag in one portion of the line were found as a result of the line inspection. In addition, the existing line was not constructed with adequate manholes for maintenance. Due to the deterioration of the sewer inceptor and impacts to the line and access road from erosion and slope sloughing, as well as inadequate manhole access, the City has proposed to make improvements to approximately 2,050 lineal feet of sewer main, approximately 35,000 square feet of access road and path, and stabilize slopes to help alleviate potential, future erosion issues (Figure 2). The project must comply with Section 106 of the National Historic Preservation Act and its implementing regulations (36 CFR 800). This document reports the results of the Cultural Resources Assessment conducted in the project area on July 11 and 12, 2017.

Evidence of these changes is visible in the character and distribution of archaeological sites, artifacts, and other remnants of their occupation. The distribution of known archaeological resources, however, has been influenced by geomorphological processes, and the history of archaeological research in the region. The present-day environmental conditions, and existing knowledge regarding pre-contact and historic Duwamish people as well as early Euro-American settlers provide a context for and helped to shape the expectations of the pedestrian survey and the investigations described in this report. 2.1 REGIONAL GEOLOGY AND GEOMORPHOLOGY The project area is situated in the Puget Trough physiographic province (Franklin and Dyrness 1988). The local topography surrounding the project area was shaped by glaciers during the Vashon Stage of the Late Wisconsin glaciation which extended up to 85 miles south of Seattle to Centralia. Resulting glacial lakes deposited silt and clay which was reworked into glacial till (Galster and Laprade 1991). As glaciers receded, a thick layer of Pleistocene glacial outwash underlying Holocene sediments across much of the Puget Sound region remained and shaped the distinctive north/south trending hills and valleys in the Puget Trough (Dragovich et al. 1994). The earliest geologic formations in the project area are Eocene-age sandstone, siltstone, and shale outcrops along with igneous sills in the hills. The Renton Formation consists of Eocene era sandstones, siltstones, conglomerates and coal deposited in a deltaic environment (Dragovich et al. 2002). Post-glacial Holocene deposits are colluvium below hillslopes and Green River and Cedar River alluvium. Other local Holocene deposits are marshes and peat along the local river bottoms. Present-day soils recorded within the boundaries of the project area consist of three defined sediment loads that include: Alderwood Gravelly Sandy Loam with a 15-30% slope, Alderwood Gravelly Sandy Loam with an 8-15% slope, and Alderwood and Kitsap Soils (NCRS 2017). Alderwood Gravelly Sandy Loam with a 15-30% slope comprises the majority of the project area with a small section of Alderwood Gravelly Sandy Loam with an 8-15% slope near the intersection of South 18 Street and Grant Avenue South. A small section of Alderwood and Kitsap Soils is located at the north end of the project area next to I-405. Alderwood Gravelly Sandy Loam with a 15-30% slope (NCRS 2017) is comprised of glacial drift and/or glacial outwash over dense glaciomarine deposits. The typical profile includes 0 to 7 inches below surface of gravelly sandy loam, followed by very gravelly sandy loam. Alderwood Gravelly Sandy Loam with an 8-15% slope (NCRS 2017) is comprised of glacial drift and/or glacial outwash over dense glaciomarine deposits. The typical profile includes 0 to 7 inches below THUNDER HILLS SANITARY SEWER INTERCEPTOR REPLACEMENT PROJECT Environmental and Cultural Setting August 11, 2017 jj g:\stantec\renton thunder hills\report\renton archeological report_2002003611.docx 2.5 surface of gravelly sandy loam, followed by very gravelly sandy loam. Alderwood and Kitsap Soils (NCRS 2017) are comprised of basalt till with some volcanic ash. The typical profile includes 0 to 12 inches below surface of gravelly ashy sandy loam, followed by very gravelly sandy loam. 2.2 CULTURAL SETTING In 2017, Stantec archaeologists reviewed ethnographic sources, reviewed hard copies of reports and records from the Washington State Historic Preservation Office (SHPO) that is maintained by the Washington State Department of Archaeology and Historic Preservation (DAHP) , searched online databases, including the online Geographic Information Systems (GIS) database called the Washington Information System for Architectural and Archaeological Records Data (WISAARD), and other archives, and reviewed previous cultural resource investigation reports, historical maps, aerial imagery, and other published sources from the region to establish the pre- contact and historical framework for the Property. The results of these background investigations are presented in the following sections to provide context for the interpretation and evaluation of cultural resources identified. 2.2.1 Regional Pre-contact Culture History Prior to the retreating glaciers in the region, little to no archaeological evidence has been identified in the Puget Sound region before 12,000 years ago (Ames and Maschner 1999; Carlson 1990). Late Pleistocene and early Holocene occupations indicate four primary cultural traditions in the Northwest Coast. These include the Fluted Point Tradition, Stemmed Point Tradition, Pebble Tool Tradition, and Microblade Tradition (for full descriptions see Ames and Maschner 1999; Carlson 1990). During this period, there is little evidence for semi-permanent village occupation, but evidence indicates that broad subsistence patterns were present within and between each tradition and that variations in technology may indicate various migrations or adaptations to changing environments or other pressures. During the middle to late Holocene, archaeological data indicate that the patterns of settlement and subsistence practices described by early ethnographers in the region were well established (Suttles and Lane 1990). 2.2.2 Ethnographic Setting The project area is located in the traditional territories of the Duwamish people (Suttles and Lane 1990). The Duwamish people spoke a Southern Luchootseed dialect of the Central Salish Lushootseed group of the Salish Language Family (Thompson and Kinkade 1990). The Duwamish occupied winter villages comprised of cedar plank houses and seasonally harvested anadromous fish, shellfish, and upland plants and game (Suttles and Lane 1990). Euroamerican exploration and settlement of the Puget Sound region began in the 1800s and increasing tensions between non-native settlers and native peoples led to negotiation of the Elliot Treaty of 1855 between the US government and the Duwamish. This treaty assigned the Duwamish people to the Port Madison Reservation on the Kitsap Peninsula which was part of the Suquamish traditional territory (Ruby and Brown 1986). Between the relocation of the Duwamish THUNDER HILLS SANITARY SEWER INTERCEPTOR REPLACEMENT PROJECT Environmental and Cultural Setting August 11, 2017 jj g:\stantec\renton thunder hills\report\renton archeological report_2002003611.docx 2.6 people in 1855 and the winter of 1856, many of the Duwamish people returned to their traditional territory or moved to the Muckleshoot Reservation (Ruby and Brown 1986). 2.2.3 Previous Archaeological Investigations and Resources On July 13 2017, a Stantec archaeologist (Justin Junge, MS) conducted a search of the records held at the Washington State Historic Preservation Office (SHPO). Descriptions of previous archaeological investigations and resources recorded within and adjacent to the project area are summarized in the following section. 2.2.3.1 Recorded Archaeological Resources A 0. 5-mile search radius around the Property was used to locate sites within survey proximity of the project area. Table 1 presents a summary of the results and a summary of the recorded archaeological resources is presented in Appendix A. Table 1. SHPO Records Search Results Record Category Within Project Site Number of Records (0.5-Mile radius) Archaeology 1 2 Cemetery None None Cultural Resources Survey 1 4 Historic Property None 160 Register None None The SHPO records revealed three archaeological resource 0.5-mile search radius around and within the project area. The archaeological sites located within 0.5 miles from the project area are listed as coal mine, structure associated with a dam, and a historic foundation. The coal mine site, 45KI211, is associated with the Renton Coal Mine which is located along the northern boundary of the project area and is listed on the Washington Heritage Register. It was not eligible for listing in the National Register of Historic Places (NRHP) (Bowden and Dampf 2005; Collins 1975; Landau Associates 2007). The historic dam and retaining wall site, 45KI767, is associated with the Talbot Road Dam which is located 0.375 miles southeast of the project area and has not been evaluated for listing on the NRHP (DAHP 2007). The historic foundation site, 45KI848, associated with the Renton Glass Factory which is located 0.2 miles north of the project area and is not eligible for listing in the NRHP (DAHP 2008; Toulouse 1971). 2.2.3.2 Historic Map Review A review of historical maps of the project area curated by the Bureau of Land Management (BLM), the US Geological Survey (USGS), and additional historic records were used to characterize the historic use and development in the project area. The 1865 General Land THUNDER HILLS SANITARY SEWER INTERCEPTOR REPLACEMENT PROJECT Field methods August 11, 2017 jj g:\stantec\renton thunder hills\report\renton archeological report_2002003611.docx 4.7 Office (GLO) survey map depicts that the northernmost portion of the project area is located in land claim no. 37 associated with the patents for Diana B. Tobin (Smithers) and Henry Heirs (H.H.) of Tobin (GLO 1865). No other use of the project area is listed until the initial construction of the sewer lines in 1965. 2.2.4 Summary of Background Research and Expectations The results of the background research conducted to date indicate, with the exception of work conducted along I-405, little archaeological research has been conducted within the project area. Characteristics of the present-day landscape, stream and stream bank stabilization due to erosion, suggests that pre-contact and historic cultural material is unlikely to be identified in the project area. 3.0 FIELD METHODS Field work involved a pedestrian survey of the project area with no wider than 10 meter transects. When vegetation or walking access restricted the 10 meter transects, exploration into the surrounding area was conducted to assess the area until transect access became available. After the pedestrian survey was completed, shovel test probes (STP) were placed judgmentally in locations that appeared to be undisturbed and where sewer replacement and repair would possibly take place. All STPs measured approximately 40-50 centimeters in diameter. All sediments were screened through 1/4" mesh screens. Upon completion of the STP, all excavated sediments was backfilled into the STP. 4.0 RESULTS Survey and testing was conducted on July 11 and July 12, 2017. Field crew consisted of Justin Junge, MS (Stantec) and Nathan Jereb, BA (Stantec). The project area was surveyed completely and one STP was excavated to test for subsurface cultural material. 4.1 PEDESTRAIN SURVEY RESULTS The pedestrian survey of the project area was conducted in two stages. The first stage was conducted to identify surface cultural material. Starting at the southern end of the project area (Figure 3), the Stantec archaeologists walked the entire project area. Due to heavy vegetation and restriction due to terrain, 10 meter transects were only viable in the northern half of the project area. Exploration into the vegetation and sloped areas above and below the access path were conducted to assess these areas. No cultural material was identified on the surface of the project area or in exposed erosional cut banks (Figure 4). In addition, the coal mine site, 45KI211, was not identified at the end of this stage of the pedestrian survey.

Overview of the Erosional Face with Nate Jereb for Scale Facing East (Photo by Justin Junge). The second stage of the pedestrian survey was conducted to identify potential locations for STPs within the project area. The project area was surveyed again beginning from the northern end of the project area near I-405. Only one location was identified as a potential location for an STP. All other cleared or flat areas were locations where buried gas a nd sewer lines are present. 4.2 SUBSURAFCE TESTING RESULTS One STP was excavated within the project area to identify the potential for subsurface cultural material. REN-STP-001 is located in the southern half of the project area (Figure 3). The STP was placed on a raised flat area above and to the east of the access path (Figure 5). A description of the sediments and other pertinent information is presented in Appendix B. The STP was terminated at 20 centimeters below surface due to impassable root systems. The area surrounding the STP also appears to be root system of the present trees or an old tree fall. No cultural material was found in the STP.

Overview of Shovel Test Probe Facing Northeast (Photo by Justin Junge). 5.0 DISCUSSION AND RECOMMENDATIONS The archaeological assessment of the project area did not identify cultural material. The soil described in the project and active erosion (Figure 4) in the project area provides little depositional context to the present sediments. Likewise, the previous stabilization work done within, i.e. placement of rock gabion walls and placing rock rip rap in the stream, along the stream bank, and where the hillside has slumped, the project area suggests that the stream area and adjoining access road are no longer original deposits. Other work near the project area, e.g. powerline construction (Figure 6 and 7), has also led to the modification of the landscape that does not support intact cultural deposits.

Overview of Vegetation beneath Southern Powerlines Facing East (Photo by Justin Junge). The only potential areas of intact cultural materials, if the construction of the apartment complexes did not remove or build-up the landscape, would be located on the terraces above the stream and outside of the project area. Looking at the active erosional faces of the slope did not identify cultural material or potential buried deposits. No additional archaeological investigations are recommended in the project area. If the ground disturbance is proposed outside the currently defined project area, i.e. terraces above the stream and access road, then archaeologists should investigate these areas to determine if pre -contact or early historic resources are present and could be affected by the proposed project activities.
