3. Can the Contractor mobilize a water tank on the Northeast corner of Parcel No. 115-210-
022 (near the fire hydrant shown in the image below) for onsite water storage during
construction?
No. The proposed location for onsite water storage during construction is on private
property. The City cannot grant access to private property. All onsite water storage shall be
located within areas of the temporary construction limits shown in the Plans. Prior to use,
the Contractor shall provide a submittal to the City for review of proposed location(s) for
onsite water storage.
4. Currently the specifications require the pipe on this project must be ASTM D3034 SDR26 or
ASTM F679 PS115. For clarification, will PS46 PVC pipe be allowed on this project?
No. ADS Sanitite PS46 is not considered equal to the specified pipe, and is therefore not
approved for use on this project.
5. Will the City allow the Contractor to tie onto the blowoff at the Sandifur intersection and get a
larger meter for construction water?
The Contractor, at their option, may elect to connect the City’s water system at the location
of a blow off assembly for the purpose of conveying construction water. Prior to connecting
to a blow off assembly, the Contractor shall provide a submittal to the City for review,
although there is no guarantee that the Contractor’s submittal for this type of connection will
be approved. Only the City will be permitted to tap into any waterline or blow off assembly.
All costs associated with this work shall be incidental to other bid items and no additional
payment will be allowed.

Management Summary
This report describes the cultural resources assessment for the City of Pasco NW Area Sewer
Project in Pasco, Franklin County, Washington. 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.

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.

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

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).

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.

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

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

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.

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.

5.2 Identified Resources
One historic debris scatter (Site-1) and the PPL 6.0 Wasteway (Property #723192) were
identified within the project location. 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

Re: Cultural Resources Assessment for the City of Pasco NW Area Sewer Project, Pasco,

Dear Johnson:
I am writing to inform you of a cultural resources assessment for the above referenced project
and to seek additional information about the project area the Tribe may have that is not readily
available through other written sources. 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.
Sincerely,
Sonja Kleinschmidt

Attachment E. 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.

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?

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).

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?

SUMMARY OF QUANTITIES
SUBSURFACE UTILITY LEGEND
THE CLASSIFICATIONS FOR SUBSURFACE UTILITIES ARE OUTLINED AND EXPLAINED IN THE FOLLOWING LIST:
UTILITY QUALITY LEVEL A. - PRECISE HORIZONTAL AND VERTICAL LOCATION OF UTILITIES OBTAINED BY
THE ACTUAL EXPOSURE OF (OR VERIFICATION OF PREVIOUSLY EXPOSED AND
SURVEYED UTILITIES) AND SUBSEQUENT MEASUREMENT OF SUBSURFACE
UTILITIES, USUALLY AT A SPECIFIC POINT. UNLESS OTHERWISE NOTED, QUALITY
LEVEL A IS ONLY APPLICABLE AT POTHOLED LOCATIONS ON THE PLANS. AT ALL
OTHER AREAS, THE UTILITY SHOULD BE ASSUMED TO BE QUALITY LEVEL B.
UTILITY QUALITY LEVEL B. - INFORMATION OBTAINED THROUGH THE APPLICATION OF APPROPRIATE
SURFACE GEOPHYSICAL METHODS TO DETERMINE THE EXISTENCE AND
APPROXIMATE HORIZONTAL POSITION OF SUBSURFACE UTILITIES.
UTILITY QUALITY LEVEL C.- INFORMATION OBTAINED BY SURVEYING AND PLOTTING VISIBLE
ABOVE-GROUND UTILITY FEATURES
UTILITY QUALITY LEVEL D. - INFORMATION DERIVED FROM EXISTING RECORDS OR ORAL RECOLLECTIONS
NOTE: THE USE OF THE LINE TYPES PROVIDED ABOVE WAS A PRIMARY METHOD FOR INDICATING THE ACCURACY OF
THE UTILITIES SHOWN WITHIN THESE PLANS. WHEN THE SOURCE OF THE INFORMATION WAS UNKNOWN OR
THE METHOD FOR LOCATING THE UTILITIES WAS UNAVAILABLE, QUALITY LEVEL D WAS USED AS THE DEFAULT.

in a written notice from the City, or fails to perform any part of the work required by the 11
Contract Documents, the City may correct and remedy such work as may be identified in 12
the written notice, with City forces or by such other means as the City may deem 13
necessary. 14
15
If the Contractor fails to comply with a written order to remedy what the City determines 16
to be an emergency situation, the City may have the defective and unauthorized work 17
corrected immediately, have the rejected work removed and replaced, or have work the 18
Contractor refuses to perform completed by using City or other forces. An emergency 19
situation is any situation when, in the opinion of the City , a delay in its remedy could be 20
potentially unsafe, or might cause serious risk of loss or damage to the public. 21
22
Direct or indirect costs incurred by the City attributable to correcting and remedying 23
defective or unauthorized work, or work the Contractor failed or refused to perform, shall 24

reject means and methods proposed by the Contractor which (1) will constitute or 51
DIVISION 1 23
create a hazard to the work, or to persons or property; or (2) will not produce finished 1
work in accordance with the terms of the Contract. 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

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

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

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

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

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

material or equipment covered by the submittal. 6
3. Approved As Noted: 7
If the review indicates that the submittal is insufficient or that limited corrections 8
are required, the submittal will be marked "APPROVED AS NOTED". The 9
Contractor may begin implementing the work method or incorporating the 10
material or equipment covered by the submittal, in accordance with the noted 11
corrections. Where submittal information will be incorporated in operation and 12
maintenance plan, a corrected copy shall be provided within 30 days, otherwise 13
no further action will be required. 14
4. Revise & Resubmit: 15
If the review reveals that the submittal is substantially insufficient or contains 16
incorrect data to an extent that requires revision and re-review by the City prior 17
to proceeding with the associated work, the submittal will be marked 18
"RESUBMIT" and returned to the Contractor. This indicated that the Contractor 19
should not proceed with the relevant portion of work, at-risk or otherwise, until a 20
revised submittal has been submitted, reviewed, and accepted by the City as 21
either “APPROVED”, or “APPROVED AS NOTED.” 22
5. Rejected 23
6. N/A: 24
If the review reveals that the submittal is not required by the Contract 25
Documents, at the City’s discretion it may be returned by the City without action 26
marked “N/A” This does not constitute review of the submittal, and is only 27
communicating that City review of this submittal is not required by the Contract 28
Documents. It is the Contractor’s responsibility to follow up with the City if the 29
Contractor needs approval of information in a submittal that was marked “N/A.” 30

of the work in areas where right of way, easements or rights of entry have not been 15
acquired until the Engineer certifies to the Contractor that the right of way or easement is 16
available or that the right of entry has been received. If the Contractor is delayed due to 17
acts of omission on the part of the City in obtaining easements, rights of entry or right of 18
way, the Contractor will be entitled to an extension of time. The Contractor agrees that 19
such delay shall not be a breach of contract. 20
The Contractor shall notify each property owner two (2) business days prior to entry. 21
This includes entry onto easements and private property where private improvements 22
must be adjusted. 23
24
Rights of way and easements obtained by the City are not guaranteed to include the 25
amount or location of land desired by the Contractor to support all of the Contractor’s 26

SUMMARY OF QUANTITIES
SUBSURFACE UTILITY LEGEND
THE CLASSIFICATIONS FOR SUBSURFACE UTILITIES ARE OUTLINED AND EXPLAINED IN THE FOLLOWING LIST:
UTILITY QUALITY LEVEL A. - PRECISE HORIZONTAL AND VERTICAL LOCATION OF UTILITIES OBTAINED BY
THE ACTUAL EXPOSURE OF (OR VERIFICATION OF PREVIOUSLY EXPOSED AND
SURVEYED UTILITIES) AND SUBSEQUENT MEASUREMENT OF SUBSURFACE
UTILITIES, USUALLY AT A SPECIFIC POINT. UNLESS OTHERWISE NOTED, QUALITY
LEVEL A IS ONLY APPLICABLE AT POTHOLED LOCATIONS ON THE PLANS. AT ALL
OTHER AREAS, THE UTILITY SHOULD BE ASSUMED TO BE QUALITY LEVEL B.
UTILITY QUALITY LEVEL B. - INFORMATION OBTAINED THROUGH THE APPLICATION OF APPROPRIATE
SURFACE GEOPHYSICAL METHODS TO DETERMINE THE EXISTENCE AND
APPROXIMATE HORIZONTAL POSITION OF SUBSURFACE UTILITIES.
UTILITY QUALITY LEVEL C.- INFORMATION OBTAINED BY SURVEYING AND PLOTTING VISIBLE
ABOVE-GROUND UTILITY FEATURES
UTILITY QUALITY LEVEL D. - INFORMATION DERIVED FROM EXISTING RECORDS OR ORAL RECOLLECTIONS
NOTE: THE USE OF THE LINE TYPES PROVIDED ABOVE WAS A PRIMARY METHOD FOR INDICATING THE ACCURACY OF
THE UTILITIES SHOWN WITHIN THESE PLANS. WHEN THE SOURCE OF THE INFORMATION WAS UNKNOWN OR
THE METHOD FOR LOCATING THE UTILITIES WAS UNAVAILABLE, QUALITY LEVEL D WAS USED AS THE DEFAULT.

WAC 197-11-960 Environmental Checklist Updated April 2020
SEPA
ENVIRONMENTAL CHECKLIST
State Environmental Policy Act
Purpose of checklist:
Governmental agencies use this checklist to help determine whether the environmental impacts of your
proposal are significant. 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. BACKGROUND
1.Name of proposed project, if applicable:
Northwest Area Sewer Local Improvement District (LID)
2.Name of applicant: City of Pasco (City) Public Works
3.Address and phone number of applicant and contact person:
Neal Schertz
Civil Engineer
525 North 3rd Avenue
PO Box 293
Pasco WA 99301
(509) 544-3080 ext. 6417
4.Date checklist prepared: September 23, 2020
5.Agency requesting checklist: City of Pasco
6.Proposed timing or schedule (including phasing, if applicable):
Final design is anticipated to be complete by late October 2020. Construction is scheduled from
December 2020 to June 2021.
7.Do you have any plans for future additions, expansion, or further activity related to or
connected with this proposal? If yes, explain.
The proposed project will serve the growing Broadmoor area development and will provide a
conveyance route to serve the western portion of the City’s potential UGA expansion area. The
Broadmoor Master Plan is currently being evaluated through the Non-Project Environmental
Impact Statement process.
8.List any environmental information you know about that has been prepared, or will be
prepared, directly related to this proposal.
None known.
9.Do you know whether applications are pending for governmental approvals of other
proposals directly affecting the property covered by your proposal? If yes, explain.
None known.
10.List any government approvals or permits that will be needed for your proposal, if known.
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.

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.

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).
