Planning Support
This Scope of Services is for professional services between Murraysmith, Inc. and Oneza &
Associates (Oneza). The intent of this work is to assist Oneza in the development of water and
sewer infrastructure requirements to serve the proposed Urban Growth Area (UGA) boundary
expansion. This includes both evaluating the capacity of the City's existing water and sewer
infrastructure to serve this new area as well as assessing the additional required infrastructure.
Murraysmith will support Oneza in identifying and confirming future infrastructure needs to
accommodate the proposed future growth and provide planning level cost estimates.
i kp" Und
Murraysmith completed a Comprehensive Water System Plan (CWSP) Update for the City in 2018
and a Comprehensive Sewer Plan (CSP) Update for the City in 2014. The UGA impact analysis being
performed by Oneza will address the City's proposed UGA expansion of 4800 acres.
Murraysmith will review potential surplus capacity in the City's existing water system facilities and
infrastructure based on the analysis in the CWSP to serve the 20 -year demands of the existing
UGA. The surplus capacity will be compared to the proposed 20 -year demand for the UGA
expansion. A conceptual layout of pressure zone boundaries, transmission piping, and any
associated facilities will be developed within the UGA expansion area. New infrastructure and/or
reasonable improvements to existing infrastructure, will be identified to extend service from the
existing service area to supply the 20 -year projections for the UGA expansion area. Where
applicable, Murraysmith will review the projects listed in the CWSP to determine potential overlap
with the infrastructure requirements to serve the UGA expansion area. Planning level costs will be
developed for any proposed infrastructure using ENR scaled unit costs developed during the
CWSP.

Pressure zone boundaries will be developed for the UGA expansion area based on available
contour data at approximately 70 foot intervals. Boundaries will be aligned with existing City
pressure zones where feasible.
Oneza will provide spatially allocated 20 -year population projections for the UGA expansion area.
Murraysmith will use the per capita demand and peaking factor assumptions from the CWSP to
allocate residential water demands in the expansion area by pressure zone. Any specific non-
residential demands for the area, including industrial, commercial, and public facilities (i.e.
schools), etc. will be provided by Oneza
Fire flow requirements for the UGA expansion will be based on the land use requirements
identified in the CWSP. Building or structure -specific fire flows will not be evaluated.
The zone boundary and demand projections will be used to determine the supply, storage, and
pumping requirements to serve the UGA expansion. The surplus capacity from the 20 -year CWSP
analysis for any applicable infrastructure will be evaluated to serve the UGA expansion. Where the
existing infrastructure is inadequate, new infrastructure and/or improvements to existing facilities
will be recommended using the design criteria in the CWSP
Transmission piping to serve the UGA will be added to the hydraulic model along with any facility
improvements from the pumping, storage and supply analysis. The demand will be allocated, and
pipe sizing will be verified using the model under the 2036 MDD, fire flow, and PHD scenarios.
Planning level costs for each recommended improvement will be developed. Unit costs from the
CWSP will be scaled using the ENR factors. New unit costs will not be developed. Capacity
improvements to the Water Treatment Plant (WTP) will be on a unit cost basis with no analysis of
the WTP processes to increase capacity
One review meeting with City staff will be conducted following the identification of improvements
to get City input and buyoff on the proposed improvements. One iteration is assumed for updates
based on City comments. If significant modifications are requested by City staff, this will be
considered additional work outside the scope of this contract.

■ Oneza or the City will provide contours or equivalent elevation information for the UGA
expansion area.
■ 20 -year population growth for the UGA expansion area will be provided by Oneza including
the spatial location for the allocation of updated future demand projections.
■ Demand projections for the UGA expansion population will be based on the per capita
future demand and peaking factors from the CWSP. For any specific non-residential
demand beyond the population based projections, Oneza will provide locations and
quantities.
■ Demand for the existing UGA will not be updated. The 2036 MDD allocation in the
hydraulic model from the CWSP will be used to evaluate existing infrastructure.
Murraysmith will utilize the existing 2036 model without modification except for the
additional UGA expansion projections provided by Oneza.
• Excess capacity in existing infrastructure will be utilized to serve the UGA expansion area
where feasible.
■ Murraysmith will utilize the design standards developed for the 2018 CWSP in the analysis.
■ Operation and maintenance costs will not be addressed.
■ Phasing plans will not be developed.
■ The hydraulic model calibration is assumed to be adequate, and additional calibration will
not be performed.

Nearly all of the UGA expansion area will be assumed to flow to the west of the existing system.
Although the CSP indicated that the West Pasco Trunk and 9th & Washington Lift Station have
limited or no capacity to serve the existing UGA 2031 flows, Murraysmith will review the capacity
in this existing infrastructure under 20 -year flow conditions to determine any reserve capacity.
Any surplus capacity will be compared to the proposed 20 -year flows for the UGA expansion. For
the small UGA expansion area east of Railroad Avenue, the capacity in the Industrial Way piping
will be analyzed to convey the flows from this portion of the expansion area. A conceptual layout
of basin boundaries, trunk line piping, and any associated lift station facilities will be developed
within the UGA expansion area. New infrastructure, or reasonable improvements to existing
infrastructure, will be identified to convey flows through the existing service area. Where
applicable, Murraysmith will review the projects listed in the CSP to determine where they overlap
with the infrastructure requirements to serve the UGA expansion area. Planning level costs will be
developed for any proposed infrastructure using ENR scaled unit costs developed during the CSP.

Sewer basin boundaries will bed eveloped for the UGA expansion area based on available elevation
data. Gravity sewer will be assumed where possible at a conceptual level.
Oneza will provide spatially allocated 20 -year population projections for the UGA expansion area.
Murraysmith will use the per capita average dry weather flow loading assumptions from the CSP
and DOE design population -based peaking factors to allocate loading in the expansion area by
basin. It is assumed that significant non-residential loading (i.e. food processing discharge in the
area east of Railroad Avenue) will be directed to the reuse facility and not through the sewer
collection system. It is also assumed that any specific non-residential flows for the area, including
other industrial, commercial, public facilities (i.e. schools), etc. will be conveyed through the
collection system, and these estimated flows will be provided by Oneza.
For basins requiring lift stations, the lift station pump capacity and force main size will be
determined. The CSP analysis indicated the 9t" & Washington Lift Station had limited or no capacity
to serve 2031 flows. As a result, a new parallel lift station will be assumed and sized to convey just
the UGA expansion area flows. New infrastructure and improvements to existing facilities will be
recommended using the design criteria in the CSP.
Trunk line piping to serve the UGA expansion will be added to the hydraulic model along with any
facility improvements from the pumping analysis. The flows will be allocated, and pipe sizing will
be verified.
Costs for each recommended improvement will be developed. Unit costs from the CSP will be
scaled using the ENR factors. No new unit costs will be developed.
One review meeting with City staff will be conducted following the identification of improvements
to get City input and agreement on the proposed improvements. One iteration is assumed for
updates based on City comments. if significant modifications are requested by City staff, this will
be considered additional work outside the scope of this contract.

■ Oneza or the City will provide contours or equivalent elevation information for the UGA
expansion area.
■ 20 -year population growth for the UGA expansion area will be provided by Oneza including
the spatial location for the allocation of updated future flow projections.
■ Sewer flow projections for the UGA expansion population will be based on the per capita
future flow from the CWSP and DOE design peaking factors. For any specific non-residential
flows beyond the population -based projections, Oneza will provide locations and
quantities.
■ Sewer flows for the existing UGA will not be updated. The 2031 dry weather and wet
weather flow allocation and piping in the hydraulic model from the CSP will be used to
evaluate existing infrastructure. Murraysmith will utilize the existing 2031 model without
modification except for the additional UGA expansion projections provided by Oneza.
Murraysmith will utilize the design standards developed for the 2014 CSP in the analysis.
■ Oneza will provide any specific non-residential flows for the UGA expansion area, including
other industrial, commercial, public facilities (i.e. schools), etc. that are to be conveyed
through the collection system,
■ Excess capacity in existing infrastructure will be utilized to serve the UGA expansion area
where feasible.
■ Murraysmith will utilize the design standards developed for the 2014 CSP in the analysis.
■ Evaluation of wastewater treatment plant capacity and performance is currently being
performed by Murraysmith under a separate contract. Therefore, specific process or
capacity improvements to the wastewater treatment plant will not be evaluated as part of
this project.
■ The 2014 CSP identified future capacity limitations in the existing West Pasco Trunk
alignment, which is the logical route for discharge from the northwest UGA expansion area
The capacity limitations are more probable based on the growth experienced in the City
since completion of the 2014 CSP, and it is assumed that the West Pasco Trunk has limited
or no capacity to serve the UGA expansion area. As a result, it is assumed that sewer flow
from the UGA expansion area will be conveyed through a new trunk line parallel to the
West Pasco Trunk.
■ The hydraulic model calibration is assumed to be adequate, and additional calibration will
not be performed.
■ Operation and maintenance costs will not be addressed.

■ Phasing plans will not be developed.
■ A summary of the assumptions, conclusions and recommendations for potable water and
sewer infrastructure to serve the expanded UGA will be provided in a draft and final
technical memorandum.
Murraysmith's effort will begin once complete population growth and non-residential water
demand and sewer flows are provided. Once these data are provided, the initial draft technical
memorandum will be completed within 2.5 months, with the final technical memorandum
completed within 2 weeks of receipt of comments on the draft report.
Murraysmith's estimated fee to perform the work identified in this scope of work is $40,000, to
be billed on a not -to -exceed, time -and -materials basis.

Scope of Work
Amendment 1
City of Pasco Comprehensive Plan Update
Additional EIS Environmental Support
1. Project Understanding
The City has hired Oneza & Associates to assist with updating its Comprehensive Plan consistent with
Washington state requirements. White Bluffs Consulting is assisting with public involvement and
environmental elements, as part of the consultant team. J -U -B Engineers is assisting with updating
and evaluating the Capital Facilities and Transportation Elements of the Comprehensive Plan.
Murraysmith is assisting with water and sewer infrastructure capacity, requirements and cost
estimate for future growth. The City of Pasco has determined this proposal could potentially have a
significant adverse impact on the environment or have increased public scrutiny, and accordingly it
has been determined that a State Environmental Policy Act (SEPA) Environmental Impact Statement
(EIS) is required. The consultant team will prepare a non -project programmatic EIS.
The following includes scope and estimated budget for developing the SEPA EIS and additional work
to update the Comprehensive Plan. Specifically, this scope includes preparing the environmental and
additional analyses. The following support activities are expected to be required for this effort:
• Additional meetings, including additional City staff, City Commissions, County Commissions and
Public Meetings. Budget for this support will be added to task 8 in the original scope of work
• SEPA EIS Environmental Analysis and Response to Comments. Budget for this support will be
added to Task 6 in the original scope of work
• Changes to land use development patterns in the proposed UGA area including commercial,
transportation corridors, parks and public lands, and any associated UGA total area updates to
support these uses
• Development of one new alternative land use scenario, in addition to revising the currently
proposed land use scenario and, and preparing existing information for one no -action scenario
• More detailed capital improvements analysis, including evaluation of state owned transportation
facilities with emphasis on the impacts of the UGA area and comparison of alternatives.
• Utilize City provided GIS data to develop a more detailed land capacity analysis
• Project Management and coordination with the City
It is expected that the timing for completion of these tasks will extend the overall project schedule by
three to six months. A more specific project schedule will be provided.

City of Pasco Comprehensive Plan Update 2018
Accompanying GIS mapping and analysis will be conducted by the City and provided to the
Consultant team for the EIS alternatives and evaluation of specific EIS elements. The City will prepare
all accompanying figures for the EIS. In addition, if needed, all additional analysis related to the
water, sewer, and storm facilities will be completed by the city or provided by the City's consultant
(Murray Smith). Cost for additional analysis by the City's consultant is not included in this scope.
2. Scope of Services and Deliverables
Task 1: Meetings with City
This task includes additional budget for coordination meetings with the City staff and consultant
team regarding EIS elements. This will also include identification of available resources, development
of a conceptual scenarios etc.
Task 2: Lead Public Involvement, Meetings Facilitation, and Working Meetings with
Agencies
This task includes time for up to five additional public meetings, meetings with the County and City
Council to discuss EIS review findings and potential mitigation strategies.
This will also include five additional working meetings with multiple departments of the City, WSDOT,
Benton -Franklin Council of Government (BFCG) and Franklin County.
Deliverables
• Presentations, inputs to staff reports, and other materials to support Public and City meetings.
Task 3: SEPA EIS Environmental Analysis and Response to Comments
This task includes budget for developing Part Four of the SEPA EIS consistent with Washington
Administrative Code (WAC) 197-11. Three alternatives will be developed for the 2018 Comprehensive
Plan Update, including one "No Action" alternative and two "Action" alternatives, including focused
evaluation of the UGA expansion area in the two action alternatives. The environmental analysis for
these alternatives would evaluate the affected environment, impacts, and mitigation measures for
ten elements of the environment, including: Earth; Surface Water: Plants and Animals; Land Use;
Shoreline Use; Population, Housing, and Employment; Parks and Recreation; Transportation; Public
Services and Utilities; and Heritage Conservation. The proposed level of detail for environmental
analysis will be programmatic and City and UGA area -wide, for those areas to develop in the future.
This task includes budget for responding to City and public comments on the SEPA EIS Part Four.
This process will include a separate City and public comment process, requiring two separate
comment/response efforts to occur for the Comprehensive Plan and the EIS. A comment/response
matrix will be used to collect and respond to comments received from the City and the public.
