EXHIBIT A
Scope of Work
City of Pasco
Road 52 and Pearl Street Lift Station Project
December 2018
Background
The City of Pasco (City) has selected RH2 Engineering, Inc., (RH2) to design its Road 52 and Pearl Street Lift
Station Project. The project is intended to expand sewer service to the East Subbasin of the Riverview Area,
which is located generally west of Road 40, east of Road 68, north of Court Street, and south of 1-182 in
Pasco, Washington. Portions of the Riverview Area are within an enclave of unincorporated Franklin County
(i.e., the "donut hole"), but are expected to be annexed into the City over the long term. The proposed
improvements are expected to generally follow the service concept for the Riverview Area included in the
City's May 2014 Comprehensive Sewer Plan. The City further evaluated the area characteristics and refined
the approximate limits of a potential subbasin to be served in the near future. The City also identified the
preliminary location of a proposed regional lift station.
The proposed improvements, which will be confirmed and/or refined by RH2 during the design phase,
include the following.
• A lift station located in the vicinity of Pearl Street and Road 52, on a City -owned parcel. The lift
station will be sized to serve approximately 663 acres, with approximately 255 acres identified by
the City as "developable". For the purpose of preparing this Scope of Work, RH2 assumes the peak
lift station capacity will be approximately 1,000 to 2,000 gallons per minute (gpm).
• Approximately 3,400 linear feet of force main piping from the lift station to discharge into the
existing gravity sewer system on Road 52 between West Sylvester Street and Court Street.
• Approximately 8,200 linear feet of gravity sewer transmission main piping to collect and convey flow
to the lift station. The City's service concept includes locating portions of the proposed gravity main
within existing United States Army Corps of Engineers (USACE) right-of-way/easements. The gravity
main is expected to extend to approximately Road 68 and West Wernett Road to the west of the lift
station and to Road 48 to the east of the lift station.
RH2 understands that this project is tied to the construction of a new fire station to be located near the
proposed lift station, and as such it is critical to construct a service line to the fire station and have the lift
station and force main operational upon the projected completion of the fire station in March 2020.
RH2 has developed a strategy to break the project into two phases in order to expedite the design and
construction of the lift station, force main, and fire station service to serve the fire station and facilitate
restoration of Road 52 during the fall 2019 or spring 2020 paving window. The remaining gravity sewer
transmission main improvements will be captured in a second phase.
The scope of work for this project includes the following major tasks, which are described in additional detail
below:
• Task 1— Hydraulic Analysis and Engineering Report
• Task 2 —Agency Coordination, Permitting, and Easement Acquisition

City of Pasco
Road 52 and Pearl Street Lift Station
• Task 3 — Phase 1 Design (Lift Station, Force Main, and Fire Station Service)
• Task 4 — Phase 2 Design (Gravity Sewer)
• Task 5 — Services During Construction (Limited)
• Task 6 — Project Management
General Project Assumptions:
Exhibit A
Scope of Work
• The designs will utilize City standard details, specifications, and materials, as well as City -provided
general contractual conditions and forms to the extent applicable. In general, sewer infrastructure will
be designed in accordance with Washington State Department of Ecology (Ecology) recommendations
per Ecology's "Criteria for Sewage Works Design."
• All design work performed -to -date for the fire station project will be provided to RH2 with the Notice
to Proceed. The City will keep RH2 informed of the project's progress regularly.
• RH2 will prepare permit submittals included in this Scope of Work and deliver them to the City. The
City will provide information that is pertinent to permit submittals to the extent it is available, pay all
permit fees, and perform final permit submittal directly to the applicable agencies.
• RH2 will prepare final bid packages and deliver them to the City. The City will submit to the appropriate
publications and pay for the advertisement as required.
• RH2 will utilize and rely upon materials, information, and data provided or produced by the City, or
others, as described within this Scope of Work.
• Comments on RH2 deliverables will be provided by the City and other agencies in a reasonable time
frame (e.g., within two [2] weeks in most cases).
• This Scope of Work separates the work into two distinct phases, but RH2 will endeavor to eliminate
any duplication of efforts. For example, this Scope splits the topographic survey and geotechnical
investigation work out for each phase in an attempt to expedite the schedule for Phase 1. If there is an
opportunity to perform the surveying and geotechnical work concurrently for both phases, RH2 will do
SO.
Time and Performance:
RH2 will begin work upon receipt of Notice to Proceed from the City and will make reasonable efforts to
complete the services within the following schedule:
• Hydraulic Analysis and Engineering Report — Two (2) months from Notice to Proceed.
• Phase 1 Design, Permitting, and Easement Acquisition (Lift Station, Force Main, and Fire Station
Service) — Five (5) months from Notice to Proceed.
Phase 2 Design, Permitting, and Easement Acquisition (Gravity Sewer) — Nine (9) months from
Notice to Proceed.
RH2 cannot be held responsible for delays, occasioned by factors beyond RH2's control, which could not
reasonably have been foreseen at the time of execution of RH2's agreement with the City.

Task 1— Hydraulic Analysis and Engineering Report
Exhibit A
Scope of Work
Objective: Perform a hydraulic analysis to determine key design criteria (i.e., pump station design flows,
recommended pump sizing and staging, recommended force main and gravity main sizing, and recommended
pump control set points and other facility operational parameters). The analysis will also confirm and refine
the spatial extent of the contributing basin, evaluate pipeline route alternatives, and make recommendations
on potential capital investment recuperation mechanisms to be presented in an engineering report. The
report will include conceptual figures and cost opinions for Phase 1 and Phase 2 that will serve as the 30 -
percent design for permitting purposes, as well as for City review and concurrence with horizontal alignments,
sizing, and facility siting.
Approach:
1.1 Prepare data request list and coordinate with the City to obtain pertinent sewer planning information,
record drawings, etc.
1.2 Review available project background information.
1.3 Confirm the extents of contributing basin and sub -basins based on available topographic data.
1.4 Evaluate the historical wastewater flow rate and load data and peaking factors based on information
provided by the City.
1.5 Estimate wastewater flow and load changes for the 10- and 20 -year projected population growth, and
buildout projections within the applicable basins and sub -basins based on information provided by the
City regarding proposed developments, projected population growth, and historical wastewater flow.
rate and load data.
1.6 Meet with the City to discuss design flows.
1.7 Prepare a suite of up to three (3) system curves for the lift station to evaluate various operating
conditions.
1.8 Coordinate with pump manufacturers to identify the preferred wastewater pumps.
1.9 Prepare duty point/operating point calculations.
1.10 Prepare wet well sizing and pump cycling calculations.

City of Pasco Exhibit A
Road 52 and Pearl Street Lift Station Scope of Work
1.20 Incorporate the City's comments and produce the final Engineering Report.
Assumptions:
• Basin delineation can be performed using aerial photography and readily available topographic data
from geographic information system (GIS) sources (i.e., prior to survey data being collected).
• Design flows can be suitably estimated based on the per capita flows and wet weather contributions
described in the City's Comprehensive Sewer Plan, or with other more accurate information provided
by the City.
• The analysis will include only a cursory review of the gravity sewer system downstream of the force
main discharge point. RH2 assumes that the gravity system downstream of the facility (and the
wastewater treatment plant) has sufficient capacity to accept peak lift station flows. RH2 will notify
the City immediately if the results of the cursory review indicate that is not the case.
• The Engineering Report is not intended to fulfill Ecology submittal requirements, since the project is
already described in the City's approved Comprehensive Sewer Plan.
Provided by the City:
• The most up-to-date version of the City's sewer model, population estimates, growth models, planned
developments, and other background information material to sewer planning. RH2 will prepare and
submit a data request to the City to help identify necessary information.
RH2 Deliverables:
• One (1) draft and one (1) final Engineering Report in electronic PDF, including figures and cost opinion.
Task 2 — Agency Coordination, Permitting, and Easement Acquisition
Objective: Prepare permit submittals and coordinate with agencies to obtain required environmental permits
and property easements/franchises. Conduct an environmental site investigation and prepare environmental
documentation and compensatory mitigation as needed. RH2 assumes the project will trigger the State
Environmental Policy Act (SEPA) process and require a Cultural Resources Assessment. RH2 also assumes that
the project will require coordination with Franklin County, Franklin County irrigation District (FCID), Franklin
County Public Utility District (Franklin PUD), and the USACE to obtain easements/franchises for pipelines
outside of City rights-of-way (ROWs). This task will also include community outreach, attendance at community
meetings, and preparation of figures and exhibits for community outreach.
Due to the difficulty in predicting RH2's level of effort coordinating with agencies in this task, the estimated
level of effort and associated hours currently attributed to this task may be imprecise. Additional authorization
may be needed if RH2's involvement exceeds the hours currently allocated in Exhibit B, Fee Estimate.
Approach:
2.1 Complete an Archaeological Resources Protection Act (ARPA) permit application and submit to USACE
prior to cultural resource site evaluation.
2.2 Perform background research, tribal contact, field observation, and final reporting documentation to
identify archaeological and historical resources in accordance with Washington State Department of
Archaeology and Historic Preservation (DAHP) guidelines. This work will be completed by Cultural
Resource Consultants, LLC (CRC) as a subconsultant to RH2. CRC will prepare an inadvertent discovery
plan (iDP) and a Cultural Resources Assessment to assess potential project impacts. Subtasks 2.1 and

City of Pasco
Exhibit A
Road 52 and Pearl Street Lift Station Scope of Work
2.2 assume that a cultural resource evaluation will be required based on the project site's location in an
area classified as 'very high risk' of cultural resource discovery by the Washington State Department of
Archaeology and Historic Preservation (DAHP) predictive model. Submit the completed Cultural
Resources Assessment to USACE. it is assumed that USACE will complete cultural reviews, including
coordination with affected Tribes and interested parties, and that no mitigation for impacts to cultural
resources will be required.
2.3 Review the existing environmental data and perform an environmental site investigation to determine
the presence/absence of wetlands in or adjacent to the project area. If wetlands are present, delineate
wetlands, flag test pits and wetland edges for subsequent surveying, characterize wetland habitat, and
complete wetland ratings. Determine wetland buffer requirements consistent with wetland ratings
and City code requirements. Complete a field map of test pit locations and wetland boundaries and
provide to R1 12's surveyor for subsequent surveying. if no wetlands are present, the level of effort for
this subtask will be reduced. It is assumed that no streams are present.
2.4 Prepare a Wetland Detailed Study in accordance with Pasco Municipal Code (PMC) Chapter 28.16
presenting results of field investigations and proposed compensatory mitigation plan, including
performance standards, monitoring, maintenance, and other required elements. This subtask assumes
that up to 700 linear feet of trenching for gravity sewer main installation will occur within wetlands.
Any wetland impacts are assumed to be temporary only and will be mitigated on-site at a 1:1 ratio.
Prepare compensatory mitigation plan and notes/details sheets for inclusion in the construction plans.
Prepare 8.5 -inch by 11 -inch plan sheets to facilitate USACE permit submittals.
2.5 Coordinate with the City and USACE on mitigation approach. Revise the Wetland Detailed Study based
on City and USACE comments.
2.6 Prepare a Joint Aquatic Resources Permit Application (DARPA) for submittal to USACE to comply with
Section 404/401 of the Clean Water Act (CWA). The project is anticipated to qualify for a Nationwide
Permit for CWA Section 404 compliance. It is anticipated that the JARPA and wetland materials will be
reviewed by USACE concurrently with easement application materials.
2.7 Prepare a draft SEPA Checklist for City staff review.
2.8 Finalize the SEPA Checklist based on City staff comments, and provide to the City Planning Staff for
completion of a SEPA Determination.
2.9 Provide up to sixteen (16) hours of coordination and correspondence with Franklin County to discuss
the planned improvements and obtain required easements/franchises and/or permits for the City to
construct, operate, and maintain the proposed sewer infrastructure planned for the Franklin County
ROW.
2.10 Prepare a Freedom of Information Act (FOIA) request to obtain USACE record drawings for their
infrastructure within the project limits.
2.11 Provide up to thirty-two (32) hours of coordination and correspondence with the USACE to discuss
planned improvements and obtain required easements/franchises and/or permits for the City to
construct, operate, and maintain the proposed sewer infrastructure planned for the USACE ROW.
Prepare required application forms and supporting documentation and submit to USACE.
2.12 Provide up to twelve (12) hours of coordination and correspondence with other utility purveyors
within the limits of work (e.g., FCID, power, gas, etc.).

Assumptions:
Exhibit A
Scope of Work
• RH2 assumes that the USACE will either convey their easements to the City or grant a Consent to
Easement to allow the City to own, operate, and maintain infrastructure in the USACE ROW. RH2
assumes that the process will be similar with Franklin County.
• The City will be the lead agency for the SEPA Checklist, which will cover both phases of the project.
• RH2 assumes that the process of obtaining easements from USACE will be categorically excluded under
the National Environmental Policy Act (NEPA) and that USACE will not require NEPA documentation
(such as an Environmental Assessment or Environmental Impact Statement) from RH2.
• No Endangered Species Act or floodplain documentation from RH2 is anticipated to be required by the
USACE.
• Identification and delineation of wetland habitat will be completed for the proposed project alignment
and areas within 100 feet.

(U. S. Army Corps of Engineers, 1987) and the Regional Supplement to the Corps of Engineers Wetland
Delineation Manual: Arid West Region (U.S. Army Corps of Engineers, 2008).
• Categorization of wetlands will be completed using the Washington State Wetland Rating System for
Eastern Washington (Ecology, 2015).
• No Ecology submittals are required because the proposed improvements are included in the City's
Comprehensive Sewer Plan.
• RH2 assumes that no City or Franklin County development review/permits will be required, and that
the square footage of the proposed lift station facility will not trigger stormwater control
requirements.
• The project is anticipated to qualify for an Erosivity Waiver, and therefore a Construction Stormwater
General Permit will not be required.
• RH2 cannot warrant or guarantee any agency's approval or response time.
• RH2 assumes that no easements will be required through private property (i.e. all improvements will
be within City -owned property, Franklin County ROW, or USACE ROW). If easements are required, RH2
generally estimates $10,000 per ownership. If required, a contract amendment will be prepared for
private property easement acquisition via subconsultant to RH2.
Provided by the City:
• The City will complete or waive any required City permits internally (e.g., City ROW permit, etc.),
except those noted herein.
• Assistance with completion of permit applications and coordination with agency staff, as needed.

Task 8 — Lift Station Basin Improvements Alternatives Evaluation
Objective: Evaluate three (3) improvement alternatives for the Lift Station Basin to determine the costs of
each alternative. Per an April 5, 2019, meeting between the City and RH2, the three (3) improvement
alternatives to be evaluated are as follows.
1) Construct the gravity trunk line within the basin, construct the lift station, and construct the
force main and gravity main in Road 52 downstream of the future lift station based on the
capacity of the projected build -out flow conditions of the basin.
2) Construct the lift station and construct the force main and gravity main in Road 52
downstream of the future lift station based on the capacity of the projected build -out flow
conditions of the basin. Construct a limited gravity main within the basin to facilitate only the
near-term development connections.
3) Construct the lift station and Road 52 force main and gravity main based on providing capacity
only for imminent development adjacent to this alignment, anticipated to be a fire station,
park restrooms, and one private development.
Approach:
8.1 Calculate the lift station pumping capacity and proposed pipe sizes for each of the three (3)
alternatives.
8.2 Prepare figures identifying the proposed improvements and sizes for each of the three (3) alternatives.
8.3 Prepare cost estimates to construct the improvements associated with each of the three (3)
alternatives.
8.4 Prepare a technical memorandum summarizing the proposed improvements and estimated costs
associated with each of the three (3) alternatives.
8.5 Meet with the City to present and discuss the results of the alternatives evaluation.
