AMENDMENT NUMBER 1 TO
PROFESSIONAL SERVICES AGREEMENT
WHEREAS, the City and RH2 Engineering, Inc. entered into a Professional Services
Agreement on September 2, 2014 to provide engineering services with respect to the East Side
Booster Pump Station Upgrade project.
NOW, THEREFORE, this agreement is amended to allow RH2 Engineering, Inc. to
provide additional engineering services as described on Exhibits A, B and C.
Scope of Work:
Professional Services with respect to the preliminary design of a future Zone 2 reservoir
and associated planning level cost estimate so it may be incorporated into the
2016-2021 Capital Improvement Project list.
2. Fee:
The compensation for the work is based on a Time and Material Basis not to exceed the
amount of $6,847.
Time of performance:
The services shall be complete for the project on or before December 31, 2015.

Storage Reservoir —10 -percent Design
May 2015
Background
In August 2014, the City of Pasco (City) selected RH2 Engineering, Inc., (RH2) to design improvements
at the East Side Booster Pumping Station (ESBPS) to meet the current and projected demands in Zone
2 of the City's water system. As part of the 30- and 60 -percent design tasks in the original contract
(Tasks 4 and 5), RH2 evaluated multiple projected demand scenarios for Zone 2 to determine the
pumping capacity required at the ESBPS. During evaluation of these demand scenarios, RH2 identified
a discrepancy between the supply capacity calculations in the City's 2010 Comprehensive Water System Plan
(WSP) and the current Washington State Department of Health (DOH) Water System Design Manual.
This discrepancy resulted in a required ESBPS capacity that is larger than identified in the WSP, and
larger than assumed as part of the original ESBPS design contract.
In March 2015, the City requested that RH2 evaluate scenarios to identify the required ESBPS capacities
under multiple future demand scenarios with and without a new storage reservoir in Zone 2. Based on
the results of RH2's future scenario evaluation, the City has requested that RH2 prepare a preliminary
design and project cost estimate for two future Zone 2 storage reservoir locations. This Scope of Work
is intended to include the work necessary to prepare a 10 -percent design and project cost estimate for a
ground -level and elevated -storage reservoir in Zone 2 of the City's water system.
Task 1— Storage Reservoir —10 -percent Design
Objective: Determine the proposed reservoir capacity and prepare a preliminary site plan for the
proposed reservoir locations.
Approach:
1.1 Calculate the storage requirements of the future reservoir based on the minimum requirements
presented in the DOH Water System Design Manual.
1.2 Prepare a technical memorandum to summarize the existing and future (20 -year) storage
analyses calculations.
1.3 Prepare a preliminary (10 -percent design) site and utility plan that shows the proposed reservoir
shell dimensions, minimum parcel dimensions, property setbacks, and major mechanical piping
to connect the reservoir to the existing water system.
1.4 Prepare two (2) renderings, one (1) each of the ground -level and elevated -storage reservoirs, at a
generic location within Zone 2 of the City's water system.

1.5 Prepare a planning -level project cost estimate for each of the ground -level and elevated -storage
reservoirs.
Assumptions:
• The preliminary site and utility plan wild be based on a generic parcel at an approximately appropriate elevation
within Zone 2 of the City's water system. A parcebby parcel reservoir siting evaluation will not be performed
• No hydraulic analyses will be performed to evaluate the ystem's conveyance capacity, potential areas of lydraulic
limitations, turnover rater, or tank transmission main .ruing.
• Structural, geological, stormwater, electrical, and control -related design elements will not be considered or shown in
the preliminary site and utility plan for each reservoir.
• Land acquisition costs will not be included in the planning -level cost estimate.
RH2 Deliverables:
One (1) 11 -inch by 17 -inch plan sheet for each of the ground -level and elevated -storage
reservoirs showing the preliminary 10 -percent design site plan, utility plan, and rendering for
each site.
• Storage analyses technical memorandum, including reservoir storage calculations.
