RH2 Engineering, Inc., on behalf of the City of Pasco, requested a cultural resources overview prior to ground disturbing activities associated with the installation of a trunk sewer to serve the developing area of Northwest Pasco. This assessment was developed to identify any archaeological or historic sites in the project location and to evaluate the potential for the project to affect cultural resources. Background research and field investigations conducted by Cultural Resource Consultants, LLC (CRC) resulted in the identification of one historic-era archaeological site and one historic inventory property. Both resources were recorded and evaluated for historic register eligibility. Neither is recommended eligible for listing on historic registers. No further investigations are recommended for the project. An inadvertent discovery protocol is provided 1.0 Administrative Data 1.1 Overview Report Title: Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Author (s): Nicole Clennon Report Date: October 30, 2020 Location: This project is located on Franklin County Assessor’s Parcel Number 115210022. Dent Rd lies to the north, Harris Rd is to the south and southeast, and Broadmoor Blvd is to the west. Legal Description: The legal description for the project is Section 7 in T 09 N, R 29 E, W.M. USGS 7.5’ Topographic Map(s): Columbia Point, WA (Figure 1). Total Area Involved: ~ 47.5 acres. Regulatory Nexus: Section 106 of the National Historic Preservation Act (NHPA). 1.2 Research Design This assessment was developed as a component of preconstruction environmental review with the goal of preventing cultural resources from being disturbed during construction of the proposed project by identifying the potential for any as-yet unrecorded archaeological or historic sites within the project. CRC’s work was intended, in part, to assist in addressing state regulations pertaining to the identification and protection of cultural resources (e.g., RCW 27.44, RCW 27.53, RCW 68.60). The Archaeological Sites and Resources Act (RCW 27.53) prohibits knowingly disturbing archaeological sites without a permit from the Washington State Department of Archaeology and Historic Preservation (DAHP), the Indian Graves and Records Act (RCW 27.44) prohibits knowingly disturbing Native American or historic graves, and the CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 2 Abandoned and Historic Cemeteries and Historic Graves Act (RCW 68.60) calls for the protection and preservation of historic era cemeteries and graves. This project was also conducted in compliance with Section 106 of the NHPA of 1966 as amended. Under Section 106, agencies involved in a federal undertaking must take into account the undertaking’ s potential effects to historic properties within the defined APE (36 CFR 800.16(l)(1)). Historic properties are typically defined as those 50 years or older. This process involves identifying and inventorying historic properties within the APE, and evaluating those properties to determine if they are eligible for listing on the NRHP. If NRHP-eligible historic properties are identified within the APE, then potential adverse effects to the historic properties must be assessed and a resolution of adverse effects recommended. CRC’s investigations consisted of review of available project information and correspondence provided by the project proponent, local environmental and cultural information, and historical maps; and field investigations. CRC contacted cultural resources staff at the Confederated Tribes of the Umatilla Indian Reservation and the Confederated Tribes and Bands of the Yakama Nation to inquire about project specific information and concerns on a technical staff-to- technical staff basis (Attachment A). This communication was not meant to be or replace formal government-to-government consultation. This assessment utilized a research design that considered previous studies, the magnitude and nature of the undertaking, the nature and extent of potential effects on historic properties, and the likely nature and location of historic properties within the project location, as well as other applicable laws, standards, and guidelines (per 36CFR800.4 (b)(1)) (DAHP 2020a). 1.3 Project Description The City of Pasco is in need of a trunk sewer main to serve the developing area of Northwest Pasco. To accomplish this, a sewer extension is proposed, running approximately 10,000 linear feet within Franklin County Assessor’s Parcel Number 115210022. For the purposes of this assessment, the area if interest for cultural resources (hereafter, “the project location”) is understood to be the area described above and depicted in Figures 1 – 3.

CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 5 2.0 Background Research 2.1 Overview Background research was conducted in February and October 2020. Recorded Cultural Resources Present: Yes [ ] No [x] No archaeological or historic sites have been previously recorded within the project. Context Overview: The context presented here summarizes environmental, ethnographic, historical, and archaeological information presented in local cultural resource reports by reference; archaeological and historic data from DAHP and the Washington Information System for Architectural and Archaeological Records Data (WISAARD) records search; ethnographic resources; geological and soils surveys (e.g., USDA NRCS 2020 WA DNR 2020); and historical maps and documents from Bureau of Land Management United States Surveyor General (USSG) Land Status & Cadastral Survey Records database, HistoryLink, Historic Map Works, HistoricAerials (NETR 2020), University of Washington’s Digital Collection, Washington State University’s Early Washington Maps Collection, county assessor website, and in CRC’s library; and historical information from King County. The following discussion of project area geology, archaeology, history, and ethnography incorporates context information from CRC’s prior work in the Tri Cities area (e.g., Berger and Hartmann 2014; Clennon 2018; Kleinschmidt 2018). 2.2 Environmental Context Overview: The project is situated on a terrace above the eastern bank of the Columbia River north of the confluence of the Yakima and Columbia rivers. The Columbia River is .60 mile southwest of the project and the mouth of the Yakima River is 1.4 miles across the Columbia to the south. The project is located within the Columbia Basin physiographic province (Franklin and Dyrness 1973). It lies within the Shrub-Steppe vegetation zone and vegetation is predominantly of the Artemisia tridentata-Agropyron association (Daubenmire 1970). The project is located northwest of downtown Pasco on undeveloped land. The elevation of the project area gently rises as the project area moves away from the Columbia River. Elevation ranges from 408 feet to 490 feet above sea level. Geomorphology: The topography and geology of the southeastern Washington region has been shaped by a unique series of geomorphological events that are reflected in the landscape of the project location. The Columbia Basin is characterized by the Columbia River Basalt Formation comprised of continental flood basalt deposits originating from more than 350 lava flows between 16.7 and 5.5 million years ago (USGS 2014). These deposits successively forced the migration of the Columbia River to its present position abutting the eastern margin of the Northern Cascade Range, characterized by north-south trending, ancient sedimentary mountains (Franklin and Dyrness 1973). The Pleistocene epoch, defined by successive glaciation during a cooler climatic period, began approximately 2.5 million years ago. During the Late Pleistocene or last glacial period (110,000- 12,000 years ago), the Cordilleran ice sheet covered much of the American northwest and scoured the landscape during advance and retreat episodes caused by localized climate CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 6 fluctuations, occasionally entering the northern Columbia Plateau. The onset of climatic warming approximately 14,000 years ago caused the ice sheets to retreat to the north and began the transition into the Holocene. During this period, large volumes of melt waters from glaciers became impounded by ice dams creating glacial lakes, such as Lake Missoula to the northeast and Lake Bonneville to the southeast. Numerous failures of these dams created catastrophic floods that inundated and scoured major parts of the Columbia Plateau in Washington (Fecht et al. 1987) down cutting the underlying basalt, widening the Columbia River Valley, and depositing massive amounts of outwash material. Pasco, Richland, and Kennewick are within the Pasco Basin. This area is characterized as extremely flat due to the deep fill of sediments deposited when the Spokane flood ponded behind the bottleneck of the Wallula Gap (Alt and Hyndman 2000:211). As previously discussed by Schumacher (2009:2-3): In the Pasco Basin, main episodes of Holocene alluvial aggradation occurred about 8,000-9,000 BP and 2,500-4,500 BP (Huckleberry et al. 1998; Lenz 2001). Early Holocene terraces are characterized by basal gravels blanketed with vertical accretion deposits that are horizontally bedded and typically overlaid with unconsolidated sandy Middle Holocene sand, silt, and gravel surface alluvium. During the Late Holocene, aeolian translocation of loess and reworking of unconsolidated dune flood sediments at lower elevations has been the primary mechanism of sediment deposition. In places, resultant sand dunes have generally been stabilized by vegetation or are present as deep, unconsolidated accumulations. Tephra deposition ensuing from various volcanic eruptions such as Mt. St. Helens (one major eruption about 13,000 BP), and Mt. Mazama (about 6,700 BP) is also present in various localities across the Pasco Basin. Tephra may be found interbedded in laminated lacustrine strata and alluvial fans, or dispersed among reworked fluvial sediments and dunes. Mapped Surface Geologic Unit(s): The surface geologic units mapped in the project location are Qf, Pleistocene outburst flood deposits and Qda, Holocene dune sand. The Qf unit is characterized as Pleistocene gravel and sandy gravel deposits with interbedded silt lenses deposited as benches along the main stem of the Snake River which came as a result of the rapid draining of glacial Lake Bonneville. In addition, the project location includes widespread silt, sand, gravel and boulder deposits that were deposited during multiple catastrophic drainings of glacial Lake Missoula. The Qda unit is characterized as Holocene well-sorted, fine to medium sand and silt in active and stable dunes that locally includes volcanic ash (WA DNR 2020). Mapped Soil Unit(s): The soil units mapped in the project location are Quincy loamy fine sand, 0 to 15 and 15 to 30 percent slopes; Quincy-Timmerman complex, 0 to 15 percent slopes; Quincy- Dune land complex, 5 to 40 percent slopes; Timmerman fine sandy loam, 2 to 5 percent slopes; Burbank gravelly loamy fine sand, 15 to 35 percent slopes; and Winchester loamy coarse sand, 2 to 5 percent slopes. Quincy loamy fine sand can be found on terraces in parent material of mixed aeolian sands. A typical profile of this soil is loamy fine sand from 0 to 4 inches below the ground surface and fine sand from 4 to 60 inches. Quincy-Timmerman complex soils can be found on terraces in parent material of mixed aeolian sands and glacial outwash and alluvium mixed with loess in the upper part. A typical profile of this soil is fine sandy loam from 0 to 5 inches below the surface, sandy loam from 5 to 19 inches, and loamy coarse sand from 19 to 60 inches. Quincy-Dune land complex can be found on terraces and in mixed aeolian sands and in unstratified fine sand and sand. A typical profile of this soil consists of two horizons of fine sand CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 7 from 0 to 60 inches below the ground surface. Timmerman fine sandy loam can be found on terraces in parent material of glacial outwash and alluvium mixed with loess in the upper part. A typical profile of this soil is fine sandy loam from 0 to 5 inches below the ground surface, sandy loam from 5 to 19 inches, and loamy coarse sand from 19 to 60 inches. Burbank gravelly loamy fine sand can be found on escarpments on terraces in parent material of outwash. A typical profile of this soil is gravelly loamy fine sand from 0 to 5 inches below the surface, gravelly loamy sand from 5 to 18 inches, very gravelly loamy sand from 18 to 38 inches, and extremely gravelly sand from 38 to 60 inches. Winchester loamy coarse sand is formed on terraces in sandy alluvium and aeolian sands. A typical profile of this soil consists of loamy coarse sand from 0 to 15 inches below the surface and coarse sand from 15 to 60 inches (USDA NRCS 2020). 2.3 Archaeological Context Archaeological evidence suggests that as the transition into an ice-free regional landscape allowed the area to be suitable for habitation in the late Pleistocene following the subsidence of glacially derived floods and the stabilization of local landforms. Subsequent changes to landforms, climate, and vegetation influenced the available resources and, consequently, the spatial distribution and subsistence strategies of humans living on the landscape. Recent investigations support human presence in northwestern North America dating to the late Pleistocene (Gilbert et. al 2008). The Pasco area falls within an area encompassed by the Columbia River Plateau Cultural Area (Anastasio 1972; Ames et al. 1998). Early human occupation on the Columbia Plateau dates to approximately 13,000 years ago and provides the upper limit of generally accepted phase designations developed from previous research for the Plateau region (e.g., Chatters 1986; Daugherty 1956; Galm et al. 1981; Greengo 1982, 1986; Hollenbeck and Carter 1986; Lohse 1985, 2005; Mehringer and Foit 1990; Nelson 1969; Rice 1969; Schalk 1982). These designations follow changes in settlement and subsistence strategies through time as climate, technology and population density changed. The trend noted in these phases is a pattern of adaptation from an upland hunting strategy to a semi-sedentary riverine- based subsistence organization over time. This change broadly occurs between an earlier tradition comprised of several phases (Clovis: ca. 11,500(?) to 11,000 B.P.; Windust: ca. 11,000 to 8000 B.P.; Vantage/Cascade: ca. 8000 to 4500 B.P.) and a subsequent, two-phase tradition: Frenchman Springs (ca. 4500 to 2500 B.P.), and Cayuse (ca. 2500 B.P. to 250 B.P.) (Ames et al. 1998; Swanson 1956) and is summarized in Berger (2015): The division between the two broad traditions is marked by the archaeological appearance of several apparent innovations. Pithouses are first recognized during this time; other artifacts appear, such as those suggestive of resource intensification (ground stone mortars, pestles, and net sinkers). Also apparent is increased variation in stone-working technology, decline in the predominance of basalt, and the appearance of small stemmed and larger notched projectile points. Archaeological evidence of a riverine-based residence pattern, supported by seasonal camps at upland locations, appears to correspond with the ethnographically observed Plateau pattern. The earliest manifestations of this residence pattern are present by about 4500 years ago. The Plateau winter village pattern, noted in ethnographic literature, appears to have been established by 2500 B.P. The Plateau subsistence model indicates a pattern of riverine settlement, a reliance on riverine and root resources, the development of complex fishing technologies, and the extension of trading patterns and extension of apparent political links (Greengo 1986; Nelson 1969; Swanson 1956). An increase in the frequency of net sinkers suggests a multifaceted economy emphasizing large-scale fishing, this possibly organized into inter-village groups. Points dated to the Cayuse period are generally smaller, with notching occasionally added to the chipped triangular form CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 8 (Nelson 1969). Bow and arrow technology appears to be widespread by about 2000 years B.P., based on the morphology of projectile points from this time period. Cultural traditions established by the onset of the Cayuse phase appear to persist with little variation to the contact era, about 200 years ago, when disruptions associated with the Euro-American presence in the region resulted in a breakdown of traditional social patterns. 2.4 Ethnographic Context Traditional Territory: The project location is within the traditional territory of the Walla Walla Wanapum, Umatilla, and Yakama peoples (Curtis 1911; Hodge 1910; Schumacher 2009a:3-4) in the Southern Plateau culture area (Chatters and Pokotylo 1998:73). Decedents of these groups are today included in the federally recognized Confederated Tribes and Bands of the Yakama Nation and the Confederated Tribes of the Umatilla Indian Reservation, and the non-federally recognized Wanapum Band of Indians. The pattern of permanent winter villages complemented by seasonal camps, typically referred to as the “Plateau pattern,” appears archaeologically recognizable in an incipient mode by about 4,000 years ago. This model for Plateau subsistence is commonly distinguished archaeologically by the presence of several features, such as riverine settlement patterns; reliance on riverine and root resources; complex fishing technologies; the extension of trading links and apparent political integration; and, shared aspects of material culture such as pithouse architecture (Schumacher 2009:3-4). Regional interaction and cross- utilization of resource areas were common results of the mobility and interaction of many Plateau peoples (Anastasio 1972; Ray 1939, 1942; Thoms et al. 1983; Wright 1997). Several sources detail ethnography of the region, including Ray (1936, 1939, 1942), Relander (1986), and Anastasio (1972). Based upon review of ethnographic information, the vicinity of the project has a high density of harvesting areas, moderate density of hunting and gathering areas, and a high density of grazing areas (Hunn et al. 2015:36, 40, 42, 44). Ethnographic Place Names: Twentieth century ethnographers documented locations of villages and names for resource areas, water bodies, and other cultural or geographic landscape features from local informants (e.g., Ray 1936). Knowledge of these features contributes to the broader archaeological context of the project area and the nature of the archaeology that may be encountered during this assessment. Large permanent villages were located in prominent locations, such as at the confluence of the Columbia River (Nch’i-Wána) and the Yakima River (Koots Koots A Min Ma) (Ray 1939, 1942). According to Schuster (1998:Figure 1), several Yakima villages were located near the confluence of the Yakima and Columbia rivers, and Walla Walla and Umatilla people also settled in the area. Chamna, the central village of the Chamnapum band (closely related to the Wanapam and Yakama), was located near this confluence. A settlement called Tomnosh was located on the east side of the Columbia River across from the mouth of the Yakima River (Relander 1986). Ray (1936:144) identifies this village as a large village and fishing site called tana'xalu, translated as “throw rocks at fish.” Relander (1986:298-299) describes named places near the confluence of the Yakima and Columbia rivers including Akachpah, the name for a small island “opposite the present city of Richland.” Tola Topepeia is the name of a spring between the Columbia and Yakima Rivers, the exact location of which has been lost (Relander 1986:298-299). Literature review and site files searches at DAHP did not identify any specific named places or sites recorded in published ethnographies within or in close proximity to the current project. CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 9 2.5 Historical Context In October 1805, the United States’ Corps of Discovery, led by Lewis and Clark, canoed westward through the region of the Tri-Cities area. Their journey attracted the attention of many local Indian people, including Umatilla, Yakama, Wanapum, Chemnapum, Palouse, Walla Walla, and Cayuse. On October 17, Lewis and two companions saw the mouth of the Yakima River (Moulton 2002). On that same day, Lewis and Clark note stopping at a village with three large lodges where they were offered boiled salmon. This is perhaps a Palouse village in Franklin County, north of present day Pasco (Moulton 2002; Trafzer and Scheuerman 1988). After 1810, fur trappers from the Pacific Fur Company, the Northwest Company of Merchants, and later the Hudson’s Bay Company had a presence along the Columbia River. During their peak, the Columbia River was one of the main arteries of trade between the coast and interior (Oberst 1978). By the 1850s, missionaries, farmers, and miners traveled into the area. Initial settlement by Euro-Americans precipitated forced displacement of Indians, and hostilities were fostered between settlers, the U.S. military, and Indian people opposed to resettlement on reservations (Cowan 2012; Oberst 1978; Schumacher 2009). A great turning point in the history of Franklin County was the construction of the Northern Pacific Railroad. According to Oberst, “Pasco’s early prosperity, and even its existence, was inextricably tied in with the Northern Pacific Railroad” (1978:15). The railroad provided many jobs and greater access to the county for emigrants. The town of Ainsworth was moved slightly upriver to Pasco and was established as a Northern Pacific Station on November 28, 1884. At that time, there was no depot nor any restaurants in Pasco. The move sparked a need to accommodate passengers traveling to and from Yakima by providing them with food and lodging. The city grew exponentially due to the opportunities the railroad provided. Between 1900 and 1915, Pasco grew in population by 803% (Oberst 1978:31). In addition to the railroad, ferry boats were often used as an alternative mode of transportation. In 1884, a successful cattle rancher, August E. Timmerman, built a cable ferry system that spanned the Columbia River at Columbia Point South. Timmerman recognized the potential at this location due to the prevailing winds, the river’s current, and the steep banks on both sides of the Columbia. The ferry crossing consisted of towers on both sides of the river connected by a 2,810-foot cable. The ferry operated until 1931, when the state bought a private toll bridge and immediately removed the toll charge making the ferry obsolete (Kubik 1994; Oberst 1978). Early Euro-American agricultural pursuits often revolved around raising livestock, most often cattle, horses, and sheep. Franklin County, receiving about 8 inches of precipitation per year, was prone to drought which when combined with overgrazing brought the cattle business to a near halt. Dryland wheat farming in the arid climate of Franklin County was a hazardous venture but a lucrative one for many farmers. Several early plans to provide irrigation to Franklin County were met with unsurmountable financial difficulties. In 1943, the Columbia Basin Project (CBP) was re-authorized by the federal government (originally authorized in 1933) (Simonds 1998:9-12). The CBP is the largest Reclamation project in Washington state and the second largest throughout the U.S. This massive undertaking has brought irrigation and waste water to more than 500,000 acres of arid land throughout central Washington (Hartmans 2012:2). The key feature of the Columbia Basin Irrigation Project, Grand CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 10 Coulee Dam, created Lake Roosevelt and Banks Lake which acted as a storage reservoir during irrigation season. Water makes its way through a network of over 331 miles of main canals, stored in a number of reservoirs, fed into 1,339 miles of lateral irrigation canals and out into 3,500 miles of drains and wasteways (Ainsbrey et al. 1978; Bloodworth and White 2008). The first irrigation water was delivered from Grand Coulee in 1952, then serving approximately 66,000 acres. However, the first irrigation of lands in the Pasco area occurred prior to the completion of these facilities. The Pasco Pumping Plant (PPP) pumps began providing irrigation water via the Pasco Pump Lateral (PPL) canal in 1948. While the CBP was designed to irrigate by gravity, the PPP alternatively provided irrigation via a large enclosed pumping plant that lifted water from the nearby Columbia River up 167 feet to Irrigation Block No. 1 (Doncaster 2014a:4). Construction of the PPL between 1946 and 1947 included “building 27.25 miles of earthwork, lining, 17 checks and 11 check-drop structures, three box culverts, 18 division boxes, 64 turnouts, 53 Parshall measuring flumes, four road bridges, and other small miscellaneous concrete structures” (Doncaster 2014a:4). Reclamation chose the PPL to serve as an experimental area to test various types of canal linings. Prior to the PPL, canals were earth-lined or concrete-lined. By the time the PPL was completed, the PPL system had 11.33 miles in asphaltic concrete lining, 6.56 miles of concrete lining, 4.44 miles of earthen wastewater ditches, and 4.91 miles of piped laterals. Additionally, the 6.56 miles of concrete-lined sections included different types of placing, with seven sublaterals lined with pneumatically applied mortar (also known as gunite) as an experiment, instead of the traditional poured-in-place concrete panels (Doncaster 2014a). The Pasco Pumping Plant’s pumps continued to serve the Pasco area until the completion of the Potholes East Canal which enabled water from the CBP to reach the PPL. At that time, the Pasco Pump Plant’s pumps were removed. 2.6 Historical Records Search Review of historical maps and aerial imagery provided an understanding of the historic and modern land use, and ownership of the project and surrounding area. The General Land Office (GLO) conducted early cadastral surveys to define or re-establish the boundaries and subdivisions of Federal Lands of the United States so that land patents could be issued transferring the title of the land from the Federal government to individuals. These maps and land serial patent records provide information on land ownership in the 1800s. The USSG (1865) map depicts the project location just north of the Columbia River (Figure 4). No trails, homesteads, Indian villages, or other cultural features are shown in the project location. The nearest mapped cultural feature is an unnamed trail, which travels along the eastern bank of the Columbia River. Early land ownership records demonstrate that the Northern Pacific Railroad Co. was issued a patent for the E½ and the E½W½ of Section 7 on October 10, 1895 (BLM Serial Nr: WAWWAA 201932; Authority: Grant-RR Northern Pacific; 337,382.45 acres) (BLM 2020). A 1917 map depicts the project location approximately .54 miles from the Timmerman Ferry operation (Figure 5; USGS 1917). On this map, a road has replaced the trail that traveled along the eastern bank of the Columbia River. An offshoot of this road travels north along the western edge Section 18, then turns east along the Section 18/Section 7 border. The project location crosses through this road at the Section boarder. The historic road follows a similar path as the CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 11 current day Court Street and Harris Road. A 1958 map does not depict this road. On this map, the Pasco Pump Lateral Canal crosses the northern end of the project area before the canal terminates (USGS 1958). A 1978 map depicts the project location crossing over numerous unnamed roads and a large sand dune as well as a segment Pasco Pump Lateral Canal system (Figure 7; USGS 1978). On this map, the canal terminates in a pond on the same parcel as the project, but outside of the project boundary. An historic county map (Metsker 1963) shows the project location as within undeveloped land owned by Shas Schmitz. According to aerial photographs and topographic maps, the majority project location is within a sand dune that remains vacant. A segment of the eastern portion of the project has been farmed continuously since prior to 1964 (Google Inc. 2020; NETR 2020). Figure 4. Approximate project location marked on cadastral survey map (USSG 1865).

CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 13 2.7 Cultural Resources Database Review DAHP WISAARD Database: A review of DAHP’s WISAARD database identified previous cultural resource studies, recorded precontact and historic sites, and recorded built environment within proximity to the project, which helps gauge the potential and likely nature of cultural resources present within the project location (DAHP 2020b). Formal archaeological survey in the Tri-Cities area began with the work of the Smithsonian Institution’s Columbia Basin Project River Basin Survey in the 1940s (Drucker 1948). Many surveys have recently been conducted along the banks of the Yakima and Columbia rivers as a part of cultural resource management efforts, with fewer surveys inland. Eighteen cultural resource assessments have been conducted within approximately one mile of the proposed project. These investigations have been completed in response to utility pole replacement or installation (Bach and Miller 2010; Hartman 2001), proposed heritage, visitor, or interpretive centers (Cooper 2003; Gilpin et al. 2008), site assessments, land surveys, and monitoring within the McNary and/or Little Goose Projects (Dickson 1999, 2011; Shellenberger and Kiona 2013, 2015), proposed docks (Hall 2013, Sharpe 2006, 2013), water supply, irrigation, and sewer line improvements (Kelly 2012a, 2012b; Miller 2013), land development (Root and Ferguson 2003; Travers 2013), road improvements (Sharpe 2009), park improvements (2016). Most of the previous studies were considered to have a moderate probability of observing cultural materials, however those closer to the Columbia River anticipated a greater likelihood of observing cultural materials due to the known exploitation of the Columbia River and previously recorded sites nearby. The Tri-Cities Archaeological District (TCAD) is located in the vicinity of Kennewick, Pasco, and Richland between river miles 330.1 and 339.9. It is .45 mile west of the project location. The TCAD was listed on the NRHP and WHR in 1984 and its boundaries were more recently updated (Solimano et al. 2012; Western Heritage, Inc. 1983). There are five recorded sites within a one-mile radius of the project location, all of which are within the TCAD (45BN23, 45BN329, 45BN46, 45FR15, 45FR16). Sites 45FR15, 45FR16, and 45BN46 are precontact campsites located .97, .70, and 1 mile to the south respectively. Site 45BN329 is located on the west bank of the Columbia River, .70 mile southwest of the project location. This site is a precontact campsite and burial. Site 45BN23, also known as Columbia Point South and Chamná, is a large precontact village and burial site. It continues to be a site of religious and cultural significance to the local tribes and is listed on the National Register of Historic Places. It is located .64 mile SW of the project location. Table 1. Archaeological sites recorded within approximately one mile from the project location. Site Number Site Type Distance from Project Historic Register Status Potential Project Effects 45BN23 Burial/Precontact Village .64 mile SW Not determined None. 45BN329 Burial/Precontact campsite .70 miles SW Not determined None. 45BN46 Precontact campsite 1 mile S Not determined None. 45FR15 Precontact campsite .97 mile S Not determined None. 45FR16 Precontact campsite .70 mile S Not determined None. No historic inventory properties have been recorded within one mile of the project location. One cemetery, archaeological site 45BN23 described above, is located within one mile of the project location. CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 14 3.1 Archaeological Predictive Models DAHP Model: The DAHP statewide predictive model uses environmental data about the locations of known archaeological sites to identify where previously unknown sites are more likely to be found. The model correlates locations of known archaeological data to environmental data “to determine the probability that, under a particular set of environmental conditions, another location would be expected to contain an archaeological site” (Kauhi and Markert 2009:2-3). Environmental data categories included in the model are elevation, slope, aspect, distance to water, geology, soils, and landforms. According to the model, the project location is ranked “Survey Highly Advised: Very High Risk” and “Survey Highly Advised: High Risk”. 3.2 Archaeological Expectations This assessment considers the implications of the predictive model coupled with an understanding of geomorphological context, local settlement patterns, and post-depositional processes to characterize the potential for archaeological deposits to be encountered. Late Pleistocene glacial events and subsequent flood episodes are responsible for much of the topography as viewed today, while aeolian processes have characterized deposition in the Holocene. Undisturbed aeolian deposits in the project location, if present, may contain buried archaeological material. Review of maps, historical aerial imagery, and historical context suggests that the project location has been disturbed to some extent by prior earthmoving activity including road construction and farming. Archaeological research and ethnohistoric accounts indicate that specific early precontact uses of the area tended toward resource-gathering and/or processing, travel, or short-term/single-use campsites. Historic-era activities would have included farming, homesteading, and the development of irrigation systems. From the late nineteenth century until the present day, the portion of the project located outside of the sand dunes was likely used for crops or grazing livestock. Given the characteristics of previously recorded archaeological sites, the project location’s land use history, and active sand dunes, the potential for the project to encounter intact archaeological deposits is considered moderate. Because of the distance to the Columbia River, precontact activities in the project location were likely more transient in nature and could have included overland travel, temporary camps, and/or resource gathering/hunting activities as well as possible ceremonial activities. Precontact materials that may be observed could include middens, caches, hearth features, fire-modified rock, lithic scatters, bone or stone tools or implements, faunal remains, and/or other materials that may represent more transient activities. Historic-era archaeological materials, if present, would likely be on or near the ground surface and consist of historic debris scatters, concentrations related to farming operations, or historic irrigation development. These resources are not anticipated to embody the potential to be significant (i.e. intact) and would not likely be eligible for listing on historic registers. 4.0 Field Investigations Total Area Examined: The entire project (~47.5 acres). Areas not examined: None. Date(s) of Survey: October 12 - 16, 2020 CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 15 Weather and Surface Visibility: Weather conditions were variable ranging from warm, windy, and sunny, to rainy, overcast, and cool. Surface visibility was generally excellent with few grasses and bushes, with the exception of near the irrigation canal. Here, there were leaves, grasses, bushes, and trees, making surface visibility poor. Field Methodology: Fieldwork consisted of pedestrian surface survey and subsurface testing via hand excavated shovel test probes. Surface survey was conducted in meandering transects along the proposed sewer extension and within areas of proposed disturbance including the temporary construction zones, providing 100 percent coverage . Probes measuring 40 centimeters in diameter were manually excavated with a shovel and all sediments were passed through 1/4-inch hardware mesh to screen for artifacts. Probes were placed every 40 meters along the proposed sewer extension and on a 40 meter grid in additional locations of proposed disturbance, excluding areas with steep slopes. The probes were recorded using a handheld GPS unit and back filled immediately after documentation. Fieldwork conducted by: Nicole Clennon and Lizzie Fellers. Notes are on file with CRC. 5.0 Results and Recommendations 5.1 Investigation Results Pedestrian survey provided information on the current condition of the project and helped to gauge the potential for as-yet unknown archaeology within the project location (Figures 7-10). Existing conditions in the project location consisted primarily of sparsely vegetated sand. Vegetation predominantly consisted of sage, rabbit brush, bitter brush, various grasses and few noxious weeds. The project location was crisscrossed with recreation vehicle tracks. A segment of the proposed sewer line running north-south had been recently farmed and was scattered with corn stalk debris on the ground surface. Another small section of the project area was compact silt that has begun to erode away in channel formations. Modern trash was observed littered throughout the project. Several larger piles of garbage were also observed. The proposed sewer line crosses a segment of the Pasco Pump Lateral (PPL) 6.0 Wasteway (Property #723192) (Figures 11-13). This earth lined canal carries wastewater through private property north of the project, through a culvert under Burns Road, and onto the parcel containing the project. The wasteway terminates at Adam’s Pond, which is outside of the current project but within the same parcel. In the area surrounding the canal and pond, the vegetation was denser and more diverse than elsewhere in the project location. Vegetation in this area consisted primarily of cottonwood trees, willows, and various grasses. The portion of the wasteway that is within the project is approximately three feet wide and flows northeast to southwest. In addition to the PPL 6.0 Wasteway (Property #723192), an historic debris scatter (Site-1) was observed during pedestrian survey (Figures 11, 14-17). The debris scatter is located approximately 20 meters north of the canal under a cottonwood canopy and is approximately 15 feet in diameter. Artifacts consist of 65 sanitary cans, 37 steel flat top beverage cans, one broken milk glass tea cup, one crème rinse bottle, two mason jars, one perfume bottle, three amber glass jug handles, five broken beer bottles, one lightbulb base, one broken Smirnoff Vodka bottle, and CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 16 miscellaneous wire. All artifacts were observed on the ground surface under recently fallen leaves. Site-1 appears to be a debris scatter that was brought in from elsewhere and dumped in this location due to the variety of artifacts. Furthermore, multiple non-historic debris piles were observed in the area and the archaeologists observed active dumping of garbage near the site location. Figure 7.

CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 22 Subsurface investigation was completed through the excavation of 99 shovel test probes within the project location (Figures 18-23; Attachment B). One hundred and four test probes were planned, however probes, 61, 74, 89, 92, 93, were not excavated due to the steep slope of the sand dunes in those locations. The majority of the shovel test probes reached 100 centimeters below the surface (cmbs), the extent of the shovel. The few probes that did not reach 100 cmbs, were terminated due to the probe caving in extremely loose sediment or due to the inability to reach deeper sediments without the probe caving in. An auger was not utilized to excavate sediment below 100 cmbs due to loose, fine sediments that could not be extracted with an auger. Subsurface conditions in the project consisted of loamy sand, fine sand, medium grain sand, coarse sand, sandy loam, and silt. Sediment was deposited by alluvial and aeolian processes and was consistent with the mapped soil units. No precontact or historic-era materials or deposits were identified during subsurface testing. The probes were backfilled immediately following documentation. Figure 18. Satellite imagery annotated with the proposed sewer extension in red and location of shovel probes.

Copies of the Archaeological Inventory Form and Historic Property Inventory are provided as Attachment C and Attachment D . 5.3 Evaluation of Significance The identified resources were evaluated for their significance based on criteria for listing on the NRHP. According to NRHP assessment criteria developed by the National Park Service (NPS), historical significance is conveyed by properties: A. That are associated with events that have made a significant contribution to the broad patterns of our history; or B. That are associated with the lives of persons significant in our past; or C. That embody the distinctive characteristics of a type, period, or method of construction or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or D. That have yielded, or may be likely to yield, information important in prehistory or history. [NPS 2002:2] According to the NRHP guidelines, the “essential physical features” of a property must be intact for it to convey its significance, and the resource must retain its integrity, or “the ability of a property to convey its significance” (NPS 2002:44). The seven aspects of integrity are: CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 26 • Location (the place where the historic property was constructed or the place where the historic event occurred); • Design (the combination of elements that create the form, plan, space, structure, and style of a property); • Setting (the physical environment of a historic property); • Materials (the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property); • Workmanship (the physical evidence of the crafts of a particular culture or people during any given period of history or prehistory); • Feeling (a property's expression of the aesthetic or historic sense of a particular period of time); and • Association (the direct link between an important historic event or person and a historic property). [NPS 2002:44] Evaluation of significance for irrigation resources of the CBP is further informed by the tiered matrix presented by Hartmans (2012:92-93, Table 3): • A 1st Tier Feature is a contributing feature individually eligible on its own merit to the NRHP and maintains a high degree of integrity; • A 2nd Tier Feature is a contributing feature not individually eligible on its own merit to the NRHP, yet maintains enough physical integrity to evoke an image of the historic irrigation system during its period of significance and it is visibly interconnected directly with other historic features of the irrigation system; • A 3rd Tier Feature could be a contributing or non-contributing feature and must be analyzed on a case by case basis; and • A 4th Tier Feature is a feature that is non-contributing and not eligible. Property #723192: Using the above criteria of eligibility, aspects of integrity, and CBP matrix (Hartmans 2012), the PPL Main Canal was recommended eligible under Criterion A because it was the first part of the CBP to be irrigated and under Criterion C for its experimental use of materials in canal linings (Doncaster 2014b). However, smaller laterals, sublaterals of the CBP, such as the PPL 6.0 Wasteway, are often deemed ineligible. In the CBP matrix (Hartmans 2012), the PPL 6.0 Wasteway would be considered a third tier resource. At times, wasteways are considered a second tier contributing feature, but because this wasteway is smaller, earthen lined, and has been altered, it is considered a third tier noncontributing feature (Hartmans 2012:92-97). Determination of Eligibility • Criterion A - While major features of the CBP have been determined eligible under Criterion A, smaller elements of the CBP have been deemed ineligible as they inadequately portray the historical significance of the CBP (Doncaster 2014:5-6). Additionally, according to Hartmans, “The landscape characteristics of the property or region must reflect the period of time in which the important events took place” (2012:79). The PPL 6.0 Wasteway is located in a rapidly developing area in northwest Pasco that no longer reflects the importance of the smaller features of the CBP. The wasteway has been altered to accommodate a well-traveled paved road, Burns Road, by the installation of a culvert. Additionally, because the wasteway is earthen lined, it has been altered annually through dredging. Furthermore, the canal will no longer be utilized CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 27 as a wasteway after fall of 2020. A new wasteway pipeline has been constructed from the PPL at mile 5.8. The culvert under Burns Road will be plugged and the new wasteway pipeline, PPL 5.8 Wasteway, will route the excess irrigation water from the PPL to the Columbia River (Bureau of Reclamation 2019). • Criterion B - Research has indicated that the PPL 6.0 Wasteway has no association with significant historical persons. Therefore it is not eligible under this Criterion. • Criterion C – The wasteway is utilitarian in design and is typical of irrigation features throughout the west. It does not embody distinctive characteristics of a type, period, or method of construction nor does the wasteway represent the work of a master. It is therefore recommended not eligible under Criterion C. • Criterion D - The PPL 6.0 Wasteway does not appear likely to yield information important to history or prehistory in the area and therefore does not meet the criteria necessary for listing on the NRHP under Criterion D. Integrity For a historic resource to be eligible it needs to possess several, if not most, of the seven aspects of integrity to convey its historical significance. The following elements addressing integrity are considered for the PPL 6.0 Wasteway: location, setting, design, materials, workmanship, feeling and association. • Location and Setting - The PPL 6.0 Wasteway has retained its original location, but the surrounding developments and construction of Burns Road has diminished the integrity of setting. • Design, Materials, and Workmanship - The wasteway retains some degree of integrity of design, however it has been diminished. The wasteway has been altered annually through dredging and a section of the wasteway has been circumvented under Burns Road through a culvert. Additionally, the wasteway will not carry wastewater after fall of 2020. Materials have been compromised by the construction of the culvert. Integrity of workmanship remains; however it was not unique like other aspects of the CBP and is typical of many canals throughout the area. • Feeling and Association - The integrity of association of the PPL 6.0 Wasteway remains, however the feeling has been diminished through alterations of the canal and will be further diminished when it no longer carries water. Site-1: Site-1 was evaluated for significance based on NRHP. • Criterion A – Site-1 is not known to be associated with any particular event that has made a significant contribution to our history. • Criterion B – Site-1 has no association with significant historical persons. Therefore it is not eligible under this Criterion. • Criterion C – The debris scatter is typical of many debris scatters throughout the west, and therefore, is recommended not eligible under Criterion C. • Criterion D – Site-1 does not appear likely to yield information important to history or prehistory in the area and therefore does not meet the criteria necessary for listing on the NRHP under Criterion D. CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 28 Site-1 is recommended as not eligible for listing. The site was recorded as a surface scatter. All probes near the site tested negative for archaeological material. The site was likely a secondary deposit brought to the current location in order to be disposed of. Artifacts consist of 65 sanitary cans, 37 steel flat top beverage cans, milk glass, crème rinse bottle, two mason jars, one perfume bottle, three amber glass jug handles, five broken beer bottles, one lightbulb base, one broken Smirnoff Vodka bottle, and miscellaneous wire. The artifacts range in age from the 1950s to the 1970s. This site has very little information potential. Additionally, the is not associated with any person of significance in our past nor associated with any particular event that has made a significant contribution to our history. 6.0 Results and Recommendations 6.1 Results Background research and field investigations, inclusive of surface survey and excavation of 99 shovel probes, resulted in the identification of an historic wasteway canal (Property #723192) and an historic debris scatter (Site-1). Both sites are recommended not eligible for historic registers (Attachment C, Attachment D). 6.2 Conclusions and Recommendations CRC conducted this assessment to determine the potential effects of this project on cultural resources. One previously unrecorded archaeological resource was identified. The site was evaluated for historic register listing based on formal criteria and was recommended not eligible for listing on historic registers. The site is located within the path of the proposed sewer line and is likely to be destroyed during construction. No precontact cultural materials or deposits were identified during the course of the survey, nor was any evidence found to suggest a high potential for archaeological deposits to be contained within the project. All probes were negative for archaeological material. One previously unrecorded historic inventory property was identified. It was recorded, evaluated, and recommended not eligible for listing on historic registers. The proposed sewer extension will be installed via an “open cut” across the wasteway and throughout the rest of the proposed project location. Water will have been diverted prior to construction by means of the PPL 5.8 Wasteway. In the event that any ground-disturbing or other construction activities result in the unanticipated discovery of archaeological resources, work should be halted in the immediate area, and contact made with county officials, the technical staff at DAHP, and tribal representatives (Attachment E). Work should be stopped until further investigation and appropriate consultation have concluded. In the unlikely event of the inadvertent discovery of human remains, work should be immediately halted in the area, the discovery covered and secured against further disturbance, and contact effected with law enforcement personnel, consistent with the provisions set forth in RCW 27.44.055 and RCW 68.60.055. 6.0 Limitations of this Assessment No cultural resources study can wholly eliminate uncertainty regarding the potential for prehistoric sites, historic properties, or traditional cultural properties to be associated with a project. The information presented in this report is based on professional opinions derived from CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 29 our analysis and interpretation of available documents, records, literature, and information identified in this report, and on our field investigation and observations as described herein. Conclusions and recommendations presented apply to project conditions existing at the time of our study and those reasonably foreseeable. The data, conclusions, and interpretations in this report should not be construed as a warranty of subsurface conditions described in this report. They cannot necessarily apply to site changes of which CRC is not aware and has not had the opportunity to evaluate. 7.0 References Ainsbrey, A. J., R. B. Hayes, H. J. Warren, D. L. Winsett, and R.

This letter is on a technical staff-to-technical staff basis to inquire about project-related cultural information or concerns. It is not intended as formal government-to-government consultation to be initiated by the appropriate regulatory agency. The project is located in Sections 6 & 7, Township 9 North, Range 29 East Willamette Meridian at north of Harris Rd and west of Broadmoor Blvd in Pasco, Franklin County, Washington. City of Pasco is overseeing design of a new sewer main. The proposed trunk sewer main is approximately 12,000 linear feet of piping, composed of three (3) segments: Segment 1 - Extending due north from Harris Road (north of I-182), through Burns Road. Segment 2 - Branching north & east to and terminating (roughly) at Broadmoor Blvd. Segment 3 - Branching north from Burns Road to and terminating (roughly) at Deseret Road. We are in the process of reviewing available information. Background research will include a site files search at the Washington State Department of Archaeology and Historic Preservation, review of previously recorded cultural resource reports, and review of pertinent published literature and ethnographies. Results of our investigations will be presented in a technical memo. We are aware that not all information is contained within published sources. Should the Tribe have additional information to support our assessment, we would very much like to include it in our study. Please contact me at sonja@crcwa.com or 360-395-8879 should you wish to provide any comments. I appreciate your assistance in this matter and look forward to hearing from you.

Inadvertent Discovery Protocol. Protocols for Discovery of Archaeological Resources The Archaeological Sites and Resources Act (RCW 27.53) prohibits knowingly disturbing archaeological sites without a permit from the Washington State Department of Archaeology and Historic Preservation (DAHP), and the Indian Graves and Records Act (RCW 27.44) prohibits knowingly disturbing Native American or historic graves. In the event that archaeological resources are encountered during project implementation, the following actions will be taken: All ground disturbing activity at the find location will stop, and the work supervisor will be notified immediately. The find location will be secured from any additional impacts. The project proponent will immediately contact the agencies with jurisdiction over the lands where the discovery is located, if appropriate. The appropriate agency archaeologist or the proponent’s contracting archaeologist will determine the size of the work stoppage zone or discovery location in order to sufficiently protect the resource until further decisions can be made regarding the work site. The project proponent will consult with DAHP regarding the evaluation of the discovery and the appropriate protection measures, if applicable. Once the consultation has been completed, and if the site is determined to be NRHP-eligible, the project proponent will request written concurrence that the agency or tribe(s) concurs that the protection and mitigation measures have been fulfilled. Upon notification of concurrence from the appropriate parties, the project proponent will proceed with the project. Within six months after completion of the above steps, the project proponent will prepare a final written report of the discovery. The report will include a description of the contents of the discovery, a summary of consultation, and a description of the treatment or mitigation measures. Protocols for Discovery of Human Remains If human remains are found within the project area, the project proponent, its contractors or permit-holders, the following actions will be taken, consistent with Washington State RCWs 68.50.645, 27.44.055, and 68.60.055: If ground-disturbing activities encounter human skeletal remains, then all activity will cease that may cause further disturbance to those remains. The area of the find will be secured and protected from further disturbance. The project proponent will prepare a plan for securing and protecting exposed human remains and retain consultants to perform these services. The finding of human skeletal remains will be reported to the county medical examiner/coroner and local law enforcement in the most expeditious manner possible. The remains will not be touched, moved, or further disturbed. The county medical examiner/coroner will assume jurisdiction over the human skeletal remains and make a determination of whether those remains are forensic or non- forensic. If the county medical examiner/coroner determines the remains are non-forensic, then they will report that finding to DAHP, which will then take jurisdiction over the remains. DAHP CRC Technical Memorandum #1912D-2 Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco, Franklin County, Washington Page 68 will notify any appropriate cemeteries and all affected tribes of the find. The State Physical Anthropologist will make a determination of whether the remains are Indian or Non-Indian and report that finding to any appropriate cemeteries and the affected tribes. DAHP will then handle all consultation with the affected parties as to the future preservation, excavation, and disposition of the remains.

QUESTIONS/CLARIFICATIONS 1. Does gravity main installed with minimal cover have to be heavy wall pipe? All proposed gravity sewer main shall be heavy wall type, as identified as Note 6 on all SS## plan sheets, including sewer main installed at depths less than 12 feet. 2. Does the City have an anticipated schedule for this project? Physical completion is required within 120 working days, as identified in Division 1-08.5. It is the City’s intention to award the construction contract to the lowest responsible bidder at a regularly scheduled December 7, 2020 City Council meeting. The Notice to Proceed is tentatively planned for late December 2020 or early January 2021. 3. Is the contractor responsible for removing grubbings from the site? The Contractor shall remove and properly dispose of all grubbings, including but not limited to shrubs, trees, and stumps, that are encountered during construction. Grubbings may be temporarily piled within the construction limits during construction, provided that they are properly secured at the end of each working day, prior to being hauled off-site and disposed of by the contractor. All associated costs thereof shall be included in Bid Item No. 3, ‘CLEARING AND GRUBBING’. 4. Is the Contractor responsible for removing or relocating miscellaneous debris or garbage encountered on the site? The Contractor shall remove and properly dispose of any miscellaneous debris or garbage (e.g. foreign objects, fragments, rubbish, refuge, etc.) encountered during construction. 5. Can the CAD files be provided to bidders? The CAD file(s) will not be provided to bidders. 6. How deep is the existing pond adjacent to proposed SSMH-6? The actual depth is unknown, but believed to be similar in depth to the empty pond to the north adjacent to proposed SSMH-10 (which was empty during the November 10, 2020, non-mandatory pre-bid meeting). 7. Is the City’s intention that the work associated with the American Rock pond piping near proposed SSMH-6 and SSMH-7 be completed prior to mid-May 2021 (i.e., prior to American Rock’s need to use these pipes next year)? Yes. All existing piping in this vicinity shall be restored and approved by American Rock no later than May 15, 2021.     Northwest Area Sewer LID    Addendum No. 02  Contract No. 1800076    Page 4    PUBLIC WORK DEPARTMENT    (509) 543‐5738 / FAX (509) 543‐5737  P.O. Box 293 (525 North 3rd Avenue) Pasco, Washington 99301 / www.pasco‐wa.gov  8. Is it acceptable to the City for the Contractor to tap the 16-inch water line on Burns and run a 6-inch stub across to the project? No. Only the City shall tap waterlines. 9. Is it acceptable to the City for the Contractor to dig under Burns and install a 6” sleeve and cold patch back for construction water? The Contractor, at their option, may elect to install a temporary sleeve below grade for the purpose of conveying construction water within the right-of-way and/or construction limits. Prior to installing a temporary sleeve, the Contractor shall provide a submittal to the City for review, although there is no guarantee that the Contractor’s submittal for a temporary sleeve will be approved by the City. The temporary sleeve shall meet the minimum requirement of 36-inch depth below finished grade to top of pipe. The Contractor is required to dig and verify existing utilities where the temporary sleeve is proposed to be located. After completion of the project, the temporary sleeve can be left in place for future use. The permanent patch shall be installed per surface restoration details on DWG No. D03. A cold patch is not permitted. All costs associated with this work shall be incidental to other bid items and no additional payment will be allowed. 10. What is the current water pressure at the City’s fire hydrants along Burns Road? Historical data provides that water pressure at fire hydrants along Burns Road is approximately 50 to 55 psig. Water pressure is dependent on water system operating conditions. The City does not guarantee the accuracy of this pressure range, which is provided for informational purposes only. Actual conditions of water at fire hydrants will be available when the Fire Hydrant Meter and Gate Valve are installed for use during construction. 11. Does the unscheduled excavation (Bid Item No. 33) include only the excavation activities, or the filling of the excavated volume with any material? Bid Item No. 33 includes only excavation of native material beyond the locations, depths, or limits shown in the Contract Documents. Placement of fill within the unscheduled excavation void is anticipated to be paid on a unit cost basis for either bedding (Bid Item No. 21), select backfill (Bid Item No. 22), CSBC (Bid Item No. 26), or CSTC (Bid Item No. 27).     Northwest Area Sewer LID    Addendum No. 02  Contract No. 1800076    Page 5    PUBLIC WORK DEPARTMENT    (509) 543‐5738 / FAX (509) 543‐5737  P.O. Box 293 (525 North 3rd Avenue) Pasco, Washington 99301 / www.pasco‐wa.gov  12. What are the fees associated with water used via a hydrant meter? Please refer to:  Information for Bidders, ‘WATER’, Page IB 1 of 5 in the Bid Documents  PMC 13.20.080, Tank Water (https://pasco.municipal.codes/PMC/13.20.080)  PMC 3.35.160, Water Utility (https://pasco.municipal.codes/PMC/3.35.160) 13. Is native material required to be mechanically screened prior to placement as backfill, or can it be removed by hand? Mechanical screening is not mandatory; however, it is anticipated that variable soil conditions will be encountered and that mechanical screening will be necessary throughout portions of the proposed alignment. In locations with high sand and gravel content and minimal cobbles, hand screening is acceptable to remove rocks greater than 3-inches in size. 14. Is there a specification for the air-blown sand for the annular space in the casings? Clean, washed, and screened medium sand is acceptable. ASTM D2487 medium sand definition: “Material passing a 2.00-mm sieve (No. 10) and retained on a 0.475-mm (No. 40) sieve.”     Northwest Area Sewer LID    Addendum No. 02  Contract No. 1800076    Page 6    PUBLIC WORK DEPARTMENT    (509) 543‐5738 / FAX (509) 543‐5737  P.O. Box 293 (525 North 3rd Avenue) Pasco, Washington 99301 / www.pasco‐wa.gov  Specification and Plan Sheet Clarifications/Changes 1.

The City's approval of the 2 Contractor's means and methods of construction or his failure to exercise his right to 3 reject such means or methods shall not relieve the Contractor of the obligation to 4 accomplish the result intended by the Contract; nor shall the exercise of such right to 5 reject create a cause for action for damages. 6 7 1-05.10 Guarantees 8 (June 26, 2020 COP GSP) 9 10 Delete this section and replace it with the following: 11 12 If defective and unauthorized materials or work is discovered within the guarantee 13 timeframe after the certification of completed public improvements date, the Contractor 14 shall promptly, upon written request, return and in accordance with the instructions 15 either correct such work, or if such work has been rejected, remove it from the Project 16 Site and replace it with non-defective and authorized work, all without cost to the City. 17 If the Contractor does not promptly comply with the written request to correct defective 18 and unauthorized work, or if an emergency exists, the City reserves the right to have 19 defective and unauthorized work corrected or rejected, removed, and replaced 20 pursuant to the provisions of Section 1-05.7 of the Standard Specifications. 21 22 1-05.11 Final Acceptance 23 24 Delete this section and replace it with the following: 25 26 1-05.11 Final Inspections and Operational Testing 27 (October 1, 2005 APWA GSP) 28 29 1-05.11(1) Substantial Completion Date 30 31 When the Contractor considers the work to be substantially complete, the Contractor 32 shall so notify the Engineer and request the Engineer establish the Substantial 33 Completion Date. The Contractor’s request shall list the specific items of work that 34 remain to be completed in order to reach physical completion. The Engineer will 35 schedule an inspection of the work with the Contractor to determine the status of 36 completion. The Engineer may also establish the Substantial Completion Date 37 unilaterally. 38 39 If, after this inspection, the Engineer concurs with the Contractor that the work is 40 substantially complete and ready for its intended use, the Engineer, by written notice to 41 the Contractor, will set the Substantial Completion Date. If, after this inspection the 42 Engineer does not consider the work substantially complete and ready for its intended 43 use, the Engineer will, by written notice, so notify the Contractor giving the reasons 44 therefor. 45 46 Upon receipt of written notice concurring in or denying substantial completion, whichever 47 is applicable, the Contractor shall pursue vigorously, diligently and without unauthorized 48 interruption, the work necessary to reach Substantial and Physical Completion. The 49 Contractor shall provide the Engineer with a revised schedule indicating when the 50 Contractor expects to reach substantial and physical completion of the work. 51 DIVISION 1 24 1 The above process shall be repeated until the Engineer establishes the Substantial 2 Completion Date and the Contractor considers the work physically complete and ready for 3 final inspection. 4 5 1-05.11(2) Final Inspection and Physical Completion Date 6 7 When the Contractor considers the work physically complete and ready for final 8 inspection, the Contractor by written notice, shall request the Engineer to schedule a 9 final inspection. The Engineer will set a date for final inspection. The Engineer and the 10 Contractor will then make a final inspection and the Engineer will notify the Contractor in 11 writing of all particulars in which the final inspection reveals the work incomplete or 12 unacceptable. The Contractor shall immediately take such corrective measures as are 13 necessary to remedy the listed deficiencies. Corrective work shall be pursued vigorously, 14 diligently, and without interruption until physical completion of the listed deficiencies. This 15 process will continue until the Engineer is satisfied the listed deficiencies have been 16 corrected. 17 18 If action to correct the listed deficiencies is not initiated within 7 days after receipt of the 19 written notice listing the deficiencies, the Engineer may, upon written notice to the 20 Contractor, take whatever steps are necessary to correct those deficiencies pursuant to 21 Section 1-05.7. The Contractor will not be allowed an extension of contract time because 22 of a delay in the performance of the work attributable to the exercise of the Engineer’s 23 right hereunder. 24 25 Upon correction of all deficiencies, the Engineer will notify the Contractor and the City, in 26 writing, of the date upon which the work was considered physically complete. That date 27 shall constitute the Physical Completion Date of the contract, but shall not imply 28 acceptance of the work or that all the obligations of the Contractor under the contract have 29 been fulfilled. 30 31 1-05.11(3) Operational Testing 32 33 It is the intent of the City to have at the Physical Completion Date a complete and 34 operable system. Therefore when the work involves the installation of machinery or other 35 mechanical equipment; street lighting, electrical distribution or signal systems; irrigation 36 systems; buildings; or other similar work it may be desirable for the Engineer to have the 37 Contractor operate and test the work for a period of time after final inspection but prior to 38 the physical completion date. Whenever items of work are listed in the Contract 39 Provisions for operational testing they shall be fully tested under operating conditions for 40 the time period specified to ensure their acceptability prior to the Physical Completion 41 Date. During and following the test period, the Contractor shall correct any items of 42 workmanship, materials, or equipment which prove faulty, or that are not in first class 43 operating condition. Equipment, electrical controls, meters, or other devices and 44 equipment to be tested during this period shall be tested under the observation of the 45 Engineer, so that the Engineer may determine their suitability for the purpose for which 46 they were installed. The Physical Completion Date cannot be established until testing 47 and corrections have been completed to the satisfaction of the Engineer. 48 49 DIVISION 1 25 The costs for power, gas, labor, material, supplies, and everything else needed to 1 successfully complete operational testing, shall be included in the unit contract prices 2 related to the system being tested, unless specifically set forth otherwise in the proposal. 3 4 Operational and test periods, when required by the Engineer, shall not affect a 5 manufacturer’s guaranties or warranties furnished under the terms of the contract. 6 7 Add the following new section: 8 1-05.12(1) Warranty 9 (******) 10 11 The Contractor shall guarantee the work for a period of one year from the date of 12 acceptance against defects in the work as described in the construction drawings and 13 project specifications and otherwise set forth in the contract documents. Contractor shall 14 start work to remedy such defects within seven (7) days of mailing notice of discovery 15 thereof by Owner and shall complete such work within a reasonable time. In emergencies 16 where damage may result from delay or where loss of service may result, such corrections 17 may be made by Owner, in which case the cost shall be borne by Contractor. In the event 18 Contractor does not accomplish corrections at the time specified, the work will be 19 otherwise accomplished and the cost of same shall be paid by Contractor. 20 21 The Contractor shall be liable for any costs, losses, expenses or damages including 22 consequential damages suffered by the City resulting from defects in the Contractor’s 23 work. This includes, but is not limited to the cost of Engineering, inspection, and 24 supervision by the City or Engineer. The Contractor shall hold the City harmless from any 25 and all claims which may be made against the City as a result of any defective work and 26 the Contractor shall defend any such claims at his own expense. 27 28 Warranty does not cover damage due to misuse by the Owner or conditions outside of 29 the Owner or Contractor’s control or exceptional events (force majeure) including war, 30 strikes, floods (water exceeding normal high water mark), rainfall in excess of 100 year 31 storm event, fire, earthquakes, high winds (over 85 mph for 3 seconds peak gust), freezes 32 below minus 10 degrees Fahrenheit (Eastern Washington), governmental restrictions, 33 vandalism, and power failures or surges.

All 5 correspondence from the Contractor constituting any notification, notice of protest, notice 6 of dispute, or other correspondence constituting notification required to be furnished 7 under the Contract, must be in paper format, hand delivered or sent via mail delivery 8 service to the Project Engineer's office. Electronic copies such as e-mails or 9 electronically delivered copies of correspondence will not constitute such notice and will 10 not comply with the requirements of the Contract. 11 12 (June 26, 2020 COP GSP) 13 Add the following new section: 14 1-05.16 Water and Power 15 16 Water Supply: The Contractor shall make necessary arrangements and shall bear the 17 costs for water necessary for the performance of the work. Water for use on the 18 projects may be purchased from the City of Pasco, and the Contractor shall arrange 19 for and convey the water from the nearest convenient hydrant or other source at his 20 own expense. The hydrants shall be used in accordance with the City of Pasco Water 21 Department regulations. 22 23 If City water is used for any work related to a project, a fire hydrant meter and gate 24 valve will need to be obtained from the City of Pasco to be used specifically for this 25 project. The City will charge the Contractor for any water used during construction. 26 The Contractor shall not operate the hydrant as a gate valve, nor shall the Contractor 27 be allowed to operate any other City owned valve. The Contractor shall provide the 28 necessary back flow prevention device when connecting to the water service. The Fire 29 Hydrant Meter requirements and the Fire Hydrant Meter Application are available at 30 the Customer Service Window and the Engineering Department. 31 32 The City reserves the right to deny the use of fire hydrants where deemed 33 inappropriate by the City. 34 Power Supply: The Contractor shall make necessary arrangements and shall bear 35 the costs for power necessary for the performance of the work. 36 37 (June 26, 2020 COP GSP) 38 Add the following new section: 39 1-05.17 Oral Agreements 40 41 The following new section shall be added to the Standard Specifications: 42 43 No oral agreement or conversation with any officer, agent, or employee of the City, 44 either before or after construction, shall affect or modify any of the terms or obligations 45 contained in any of the City-approved documents. Such oral agreement or 46 conversation shall be considered as unofficial information and in no way binding upon 47 the City, unless subsequently put in writing and signed by the City. 48 49 DIVISION 1 27 1-06 Control of Material 2 3 1-06.1 Approval of Materials Prior to Use 4 (******) 5 6 Revise the first paragraph to read: 7 8 Product substitution requests shall be submitted by the Contractor to the Engineer in 9 advance of associated submittals. 10 Prior to purchasing any materials for use, the Contractor shall submit documentation 11 to the City of all proposed material. The Contractor shall use the Request for Approval 12 of Material (RAM) form, WSDOT Form 350-071, which shall be provided to the City as 13 a submittal. Materials included in the WSDOT Qualified Products List (QPL) but not in 14 the City's Construction Standards will be taken under consideration by use of the RAM 15 form. 16 17 Submittal review is only for general conformance with the design concept and the 18 information given in the Contract Documents. Submittal review and the associated 19 comments do not constitute a complete verification of the submittal, and do not relieve 20 the Contractor from compliance with the Contract Documents. Review and approval 21 of a specific item shall not constitute review and approval of the associated assembly 22 of which the item is a component. The Contractor is responsible for compatibility of 23 assembly components. The Contractor is additionally responsible for: dimensions to 24 be confirmed and coordinated at the jobsite; information that pertains solely to the 25 fabrication process or to the means, methods, techniques, sequences and procedures 26 of construction; coordination of the work with that of all other trades, and performing 27 all work safely and with good workmanship. Any deviation from the Contract 28 Documents by the Contractor shall be clearly noted. Any such deviation not noted has 29 not been reviewed. Any fabrications or other work performed in advance of the receipt 30 of approved submittals shall be entirely at the Contractor’s risk and expense. 31 32 Submittal Process 33 34 Processing Time 35 36 Allow time for submittal review, including time for resubmittals, as follows. Time for 37 review shall commence on City’s receipt of submittal. No extension of the Contract time 38 will be authorized because of failure to transmit submittals enough in advance of the 39 work to permit processing, including resubmittals. 40 41 1. Initial Review: 42 Allow ten (10) working days for initial review of each submittal. Allow additional 43 time if coordination with subsequent submittals is required.

This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision- making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the Supplemental Sheet for Non-Project Actions (part D). Please completely answer all questions that apply and note that the words "project, applicant," and "property or site" should be read as "proposal, proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects) questions in Part B (Environmental Elements) that do not contribute meaningfully to the analysis of the proposal. WAC 197-11-960 Environmental Checklist Updated April 2020 A.

WAC 197-11-960 Environmental Checklist Updated April 2020 The following approvals are anticipated for the project: • Right-of-Way Permit – Franklin County (County) 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The City proposes to construct approximately 11,000 linear feet of gravity sewer transmission main to connect the growing Broadmoor area of West Pasco to the existing sanitary sewer system. The design includes 30-, 24-, and 12-inch-diameter gravity sewer main with three connections (8- and 21-inch-diameter pipe) to adjacent parcels. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The proposed project site is located within the City limits and construction will be performed primarily within easements on privately-owned parcel no. 115210022. From Harris Road, the project alignment extends north through an unimproved, gravel access roadway and undeveloped sagebrush area on the subject parcel, and then traverses east, parallel to Burns Road, within County right-of-way (ROW), extending to Broadmoor Boulevard. The project is within Section 7 of Township 9 North and Range 29 East. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site: (circle one): Flat, rolling, hilly, steep slopes, mountainous, other _____________ b. What is the steepest slope on the site (approximate percent slope)? The site is primarily flat with some varying terrain associated with sand dunes and the adjacent rock quarry. The steepest slopes onsite are approximately 10 percent. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. WAC 197-11-960 Environmental Checklist Updated April 2020 The majority of the proposed sewer main alignment is mapped within the Quincy-Timmerman complex, 0 to 15 percent slopes, soil map unit and the Quincy loamy fine sand, 15 to 30 percent slopes, soil map unit. These soils develop on terraces from wind-deposited sediments and are typically a loamy fine sand underlain by a fine sand. They are not classified as hydric soils, but the Quincy-Timmerman complex is classified as prime farmland if irrigated. The existing soils will be restored following construction of the project and no net loss of farmland soil is anticipated. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. Approximately 48,000 cubic yards (cy) of material will be excavated and approximately 48,000 cy of fill material will be required for construction of the sewer main. Fill material shall be consistent with recommendations in the project Geotechnical Engineering Report (Shannon & Wilson, Inc., 2020) and will be provided by the contractor and approved by the engineer at the time of construction. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Yes, erosion could occur. However, as most construction of the proposed sewer main will be performed within areas of gentle slopes, the risk of erosion from project construction is generally low. Work near the steeper areas in the Burns Road ROW has the potential for more erosion; the contractor will be responsible for installing and maintaining erosion control measures if rain- induced erosion and/or rilling occur. Wind erosion is possible with excavation and grading during construction but is expected to be minor due to winter and spring construction timing. In general, construction will be required to employ temporary erosion and sedimentation control (TESC) and best management practices (BMPs) to prevent and manage temporary impacts from erosion and sedimentation. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? No additional impervious surfaces will result from the project. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: BMPs anticipated to be utilized during construction of the proposed sewer main include, but are not limited to, constrained construction limits, securing temporary stockpiles and slopes, use of silt fencing, and daily site cleanup. Construction stormwater BMPs will be implemented per the Stormwater Management Manual for Eastern Washington (Ecology, December 2014). WAC 197-11-960 Environmental Checklist Updated April 2020 2. Air a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Temporary exhaust and dust emissions from construction equipment and vehicles are anticipated during construction. The completed project will not produce any emissions. There will be no long-term increase in emissions as a result of operations and maintenance of the proposed sewer main. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. None known. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Construction equipment and vehicles shall conform with Washington State standards for air quality, including using properly functioning equipment and vehicles, using clean-burning fuels when possible, limiting diesel exhaust, limiting vehicle idling, etc. BMPs to reduce and control air emissions shall be included in the project design and specifications, as applicable. 3. Water a. Surface Water: i. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The proposed sewer main alignment is in proximity to a mapped wetland and stream channel (Type U (unclassified) per the Washington State Department of Natural Resources’ (DNR) Forest Practices Activity Mapping Tool) associated with the irrigation canal system, as well as two artificial lagoons. Ongoing environmental analysis for the Broadmoor area indicates that these waterbodies were artificially constructed and are not regulated as critical areas by the City or as Waters of the State. ii. Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes. The project will require crossings (either through open-cut trench excavation or trenchless methods) of the artificial stream channel. The sewer main construction will occur in proximity to the artificial lagoons and wetland. WAC 197-11-960 Environmental Checklist Updated April 2020 iii. Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. iv. Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. v. Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. No. vi. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground Water: i. Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No. ii. Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: domestic sewage; industrial, containing the following chemicals…; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None. c. Water Runoff (including stormwater): i. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. Water runoff on the site would be in the form of stormwater (quantities unknown). Because the proposed project area is primarily undeveloped, stormwater would either infiltrate into the WAC 197-11-960 Environmental Checklist Updated April 2020 existing soil or flow downgradient towards the irrigation-induced wetland and stream system previously described. Runoff on the paved roadway portions on Harris Road will drain to the existing stormwater system. ii. Could waste materials enter ground or surface waters? If so, generally describe. No. iii. Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. No. d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: TESC measures and BMPs will be implemented to avoid and minimize impacts to nearby surface waters during project construction. Project design adheres to applicable local, state, and federal regulations, that provide standards to reduce and control impacts to surface, ground, and storm waters and drainage patterns. 4. Plants a. Check the types of vegetation found on the site: _ x __deciduous tree: alder, maple, aspen, other: willows, Russian olive _ __evergreen tree: fir, cedar, pine, other: spruce _ x __shrubs: sagebrush, bitterbrush _ x _ grass ____pasture ____crop or grain ____ Orchards, vineyards or other permanent crops. ___ wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other ____water plants: water lily, eelgrass, milfoil, other __x_other types of vegetation: forbs b. What kind and amount of vegetation will be removed or altered? Up to approximately 58,000 square feet (sf) (1.3 acres) of moderately functioning sagebrush steppe vegetation dominated by basin big sagebrush (Artemisia tridentata tridentata), gray rabbitbrush (Ericameria nauseosa), and cheatgrass (Bromus tectorum) will be removed for construction of the proposed sewer main. Much of the existing vegetation has been previously disturbed by utility terrain vehicle (UTV) traffic. c. List threatened and endangered species known to be on or near the site. WAC 197-11-960 Environmental Checklist Updated April 2020 Based on a review of DNR’s Natural Heritage data and U.S. Fish and Wildlife Service (USFWS) Information for Planning and Consultation (IPaC) data, no threatened or endangered plant species are known to be on or near the proposed project site. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: The area is planned for development within the next few years; therefore, no reseeding or revegetation of disturbed areas is proposed. e. List all noxious weeds and invasive species known to be on or near the site. Cheatgrass (Bromus tectorum), tumble mustard (Sisymbrium altissimum), Russian thistle (Kali tragus), Russian olive (Elaeagnus angustifolia), and knapweed (Centaurea sp.) are present on the site. 5. Animals a. List any birds and other animals which have been observed on or near the site or are known to be on or near the site. Examples include: birds: hawk, heron, eagle, songbirds, other: magpie, kestrel mammals: deer, bear, elk, beaver, other: rabbit, voles fish: bass, salmon, trout, herring, shellfish, other: other: lizards b. List any threatened and endangered species known to be on or near the site. Burrowing owl (Athene cunicularia), a State candidate species, is mapped within the proposed project site. However, no burrows were observed along the project alignment, much of which is within disturbed access roadway. The USFWS IPaC database indicates federally-listed species grey wolf (Canis lupus) and yellow-billed cuckoo (Coccyzus americanus) may be present within the project area. However, no suitable habitat for those species is present in proximity to the site. c. Is the site part of a migration route? If so, explain. Yes, the City is within the Pacific Flyway; therefore, the project site may provide habitat for migratory bird species. d. Proposed measures to preserve or enhance wildlife, if any: No measures are proposed since construction of the proposed sewer main will be predominantly in previously disturbed areas, sand dunes, or areas providing low quality habitat (i.e. disturbed sagebrush steppe with invasive plant species). WAC 197-11-960 Environmental Checklist Updated April 2020 e. List any invasive animal species known to be on or near the site. None known. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Gasoline and oil will be used to fuel construction equipment and vehicles throughout construction of the proposed sewer main. Electricity may also be used to power equipment during construction. The completed project will not require additional energy needs. b.

Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity. Construction of the proposed sewer main will cross beneath a natural gas pipeline operated by Cascade Natural Gas located south of Burns Road. WAC 197-11-960 Environmental Checklist Updated April 2020 iii. Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project’s development or construction, or at any time during the operating life of the project. Construction of the proposed sewer main will utilize oil- and gas-fueled equipment that may require temporary fuel storage onsite. These uses do carry some risk of spill; however, the risk should be minimized by implementation of spill control requirements outlined in the project plans and specifications and guidance from the Washington State Department of Ecology’s Criteria for Sewage Works Design (rev. October 2006). iv. Describe special emergency services that might be required. None known. v. Proposed measures to reduce or control environmental health hazards, if any: No additional measures beyond those previously mentioned. b. Noise i. What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? None anticipated. ii. What types and levels of noise would be created by or associated with the project on a short- term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Short-term construction noise will occur throughout construction of the proposed sewer main. The contractor will be required to follow regulations set forth in Chapter 9.130 of the Pasco Municipal Code (PMC), including controlling the level and timing of noise generated during construction. iii. Proposed measures to reduce or control noise impacts, if any: Construction activities and proposed site improvements shall comply with the noise regulations of PMC. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? Will the proposal affect current land uses on nearby or adjacent properties? If so, describe. The project site is currently undeveloped and land use is designated as low-density residential. Adjacent properties are mixed residential, mixed residential/commercial, and commercial.

Proposed measures to reduce or control light and glare impacts, if any: Not applicable. 12. Recreation a. What designated and informal recreational opportunities are in the immediate vicinity? There are informal UTV trails on located parcel no. 115210022, in proximity to and crossing the proposed alignment. b. Would the proposed project displace any existing recreational uses? If so, describe. Construction of the proposed project may temporarily impact UTV use of the site but will not have long-term recreation impacts. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: The contractor will employ traffic and pedestrian control during construction in established roadways and shall minimize impacts to recreational uses of the area to the extent practicable. 13. Historic and Cultural Preservation WAC 197-11-960 Environmental Checklist Updated April 2020 a.Are there any buildings, structures, or sites located on or near the site that are over 45 years old listed in or eligible for listing in national, state, or local preservation registers located on or near the site? If so, specifically describe. No. b.Are there any landmarks, features, or other evidence of Indian or historic use or occupation? This may include human burials or old cemeteries. Are there any material evidence, artifacts, or areas of cultural importance on or near the site? Please list any professional studies conducted at the site to identify such resources. No landmarks, features, or other evidence of historic use of the site is known or has been previously documented. c.Describe the methods used to assess the potential impacts to cultural and historic resources on or near the project site. Examples include consultation with tribes and the department of archeology and historic preservation, archaeological surveys, historic maps, GIS data, etc. The Washington Information System for Architectural and Archaeology Records Data (WISAARD) database was used to assess impacts to cultural and historic resources. The WISAARD predictive model shows the majority of the proposed project is within areas with very high or high risk of encountering historic resources. Due to the high potential to encounter historic resources, Cultural Resource Consultants (CRC) will be completing a cultural survey of the site and resultant Cultural Resources Assessment. d.Proposed measures to avoid, minimize, or compensate for loss, changes to, and disturbance to resources. Please include plans for the above and any permits that may be required. CRC’s report will provide additional information on cultural resources, make a determination on whether historic resources are likely to be affected by the project, and recommend any mitigation measures deemed necessary to minimize risk to historic resources. As needed, CRC’s recommendations will be incorporated into the project specifications. 14. Transportation a.Identify public streets and highways serving the site or affected geographic area and describe proposed access to the existing street system. Show on site plans, if any. The proposed project area can be accessed via Harris Road or Broadmoor Boulevard from Interstate-182. b.Is the site or affected geographic area currently served by public transit? If so, generally describe. If not, what is the approximate distance to the nearest transit stop? WAC 197-11-960 Environmental Checklist Updated April 2020 The area is served by Ben-Franklin Transit (BFT). The nearest bus stop is located on Broadmoor Boulevard near the intersection with St. Thomas Drive and is approximately 0.6 miles from the project site. c.How many additional parking spaces would the completed project or non-project proposal have? How many would the project or proposal eliminate? None. d.Will the proposal require any new or improvements to existing roads, streets, pedestrian, bicycle or state transportation facilities, not including driveways? If so, generally describe (indicate whether public or private). No. e.Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. No. f.How many vehicular trips per day would be generated by the completed project or proposal? If known, indicate when peak volumes would occur and what percentage of the volume would be trucks (such as commercial and nonpassenger vehicles). What data or transportation models were used to make these estimates? None. g.Will the proposal interfere with, affect or be affected by the movement of agricultural and forest products on roads or streets in the area? If so, generally describe. No. h.Proposed measures to reduce or control transportation impacts, if any: Throughout construction, the contractor will provide traffic and pedestrian control in work areas as needed and in compliance with City and County ROW construction standards. 15. Public Services a.Would the project result in an increased need for public services (for example: fire protection, police protection, public transit, health care, schools, other)? If so, generally describe. No. b.Proposed measures to reduce or control direct impacts on public services, if any.
