III. DESCRIPTION
A. Back r
The Meridian water system currently has 2.5 million gallons of available storage
that is provided by a 0.5 million gallon elevated tank and a 2 million gallon
ground-level tank with booster pumps. According to the Water Master Plan
Update of 2006, the City needs to begin design and construction of a 2 million
Page 1 of 3
gallon storage facility in 2010. When combined with the City's existing 2.5
million gallon storage capacity the proposed 2 million gallon storage facility,
along with additional planned supply wells, will provide enough system-wide
storage capacity to satisfy the anticipated peaking and fire fighting requirements
through 2025.
B. Proposed Project
This task order will provide the City of Meridian with engineering design services
fora 2 million gallon storage reservoir and booster pumps. The reservoir and
boosters will be located on the recently purchased property near the intersection
of Locust Grove and Victory along Ten Mile Creek.
Included with the construction of the reservoir and booster pump station, a
pathway and landscaping will be constructed along Ten Mile Creek.
C. Consultant Selection
The consultant was chosen from the recently selected professional engineering
services roster due to their familiarity with the project scope and quality of the
service they have provided in the past for the City.
IV. IMPACT
A. Strate ig c Impact:
Design and construction of the reservoir and booster pumps will ensure the City
meets the strategic objective to develop infrastructure and programs to effectively
provide uninterrupted water supply and fire suppression.
B. Service/Deliver~Impact:
The reservoir will provide water storage that will increase the redundancy and
robustness of the City's water system and decrease our dependence on
instantaneous pumping capacity. The reservoir will provide flows at peak and
emergency periods. It will provide the instantaneous pumping capacity
equivalent to several wells.
D. Fiscal Impact:
The Ground Reservoir enhancements for FY 2010 and FY 2011 were approved
for $100,000 each year. The project consultant agreement for FY 2010 was
$100,000, with an additional $65,613 in FY 2011. We are requesting the
remaining $65,613 this fiscal year to finish the design portion of the project.

VI. TIME CONSTRAINTS
The design of the reservoir and booster pump station has an expected completion
date of December of 2010. Council's approval of this task order allows the
design to be completed in calendar year 2010. The above schedule keeps the
budget and project completion rate on track with the Capital Improvements Plan.
Construction of the reservoir has been postponed to 2013, which allows time for
regulatory agency review and approval, annexation of the property, and
neighborhood meetings to address neighboring property owner's
concerns/comments.

TASK ORDER NO. 10010
Between
CITY OF MERIDIAN
AND
CH2M HILL
This Task Order is issued by City and accepted by the Engineer pursuant to the
mutual promises, covenant and conditions contained in the Master Agreement
between the above mentioned parties dated April 13, 2010.
Ground Reservoir #2
Task Order 10010
Project Understanding
The City plans to construct a new potable water storage reservoir and booster pump
station on the parcel of land approximately 800 feet south of East Victory Road and
immediately east of South Locust Grove Road. It is expected that the above-grade
reservoir will have a storage capacity between 2 and 3 million gallons. The reservoir
will be constructed of welded steel.
The design of the new booster pump station is expected to be similar to the pump
station located adjacent to the existing Ustick Reservoir. The pump station will
house the following systems and components: booster pumps; chlorination
equipment; mechanical, electrical, and plumbing systems; level sensor
instrumentation and booster pumps SCADA controls; and standby generator.
Planning will also be included for a future well to be constructed on the site adjacent
7f AAAY2010 PAGE 10F 75
to the pump station. The pump station will be designed for future expansion to
include the well house.
Site work for the project is expected to include the following construction: distribution
and supply piping on the reservoir site; excavation and fill; finished grading; access
roadway; sidewalks; site drainage; fencing; and minimal landscaping. The site
design will also include a new asphalt path for pedestrians and bicyclists. The path
will be located on the north side of Ten Mile Creek and will be designed in
accordance with the recommendations of the Meridian Pathways Master Plan (dated
January 2010).
It us our understanding that the proposed site is currently unincorporated but that
the City will annex the property, and that the project will therefore be designed
according to City planning & zoning requirements (as opposed to Ada County
requirements}. It is also our understanding that the City owns all property associated
with this project, and that no rights-of--way or easements will be required.
A topographic survey and a geotechnical field exploration wilt be performed so that
the planned facilities can be properly designed and located on the site. A
geotechnical evaluation of the site will be performed to gather site-specific
subsurface information and collect soil samples for class cation and laboratory
testing. The site will also be surveyed for wetlands or other sensitive areas. These
sensitive areas will be delineated on the final site plan, and the contractor will be
required to take necessary steps to protect these areas.
The proposed location of the reservoir and pump station is located in the floodplain
of Ten Mile Creek; the project is therefore required by the Federal Emergency
Management Agency (FEMA) to perform a flood analysis to evaluate impacts
associated with the reservoir and pump station construc#ion. A hydraulic model will
be produced based on existing modeling to be furnished by FEMA.
CH2M HILL understands that the City has contacted the US Army Corp of
Engineers (USAGE) to determine if they would have interest in funding a portion of
the project. Since the USAGE has not responded at the time of the preparation of
this scope, CH2M HILL has assumed that the USAGE will not be involved in the
project. This task order would need to be amended to include any project changes
or impacts associated with USAGE involvement in the project.
Scope of Work
CH2M HILL will perform the tasks for the design of the new reservoir and boaster
pump station as outlined below.
Task 1--Project Management
1.1 Staff Management and Task Coordination
Project management will consist of supervising project staff, holding consultant staff
coordination meetings, documenting meeting decisions and action items, and
assigning activities to team members.
19 MAY 2010 PAGE 2 OF 15
1.2 Monitor Project Progress
Monitor project progress, including work completed, work remaining, budget
expended, schedule, estimated cost of work remaining, and estimated cost at
completion. Monitor project activities for potential changes, anticipate changes when
possible, and with City approval, modify project tasks, budgets, and approach.
1.3 Invoices
Prepare and submit invoices for services pertormed on a monthly basis, including a
brief summary of work completed.
1.4 Project Quality Control
Coordination and facilitation of project quality control reviews of all deliverables on
this project. Senior technologists will be involved in the work tasks and perform
necessary reviews at deliverable milestones.
1.5 Opinions of Probable Costs.
An opinion of probable construction cost will be prepared at each of the preliminary
design and 90% design submittals to the City.
1.6 Schedule Evaluation
An evaluation of the anticipated project schedule will be prepared at each of the
preliminary design and 90% design submittals to the City. The schedule evaluation
will include the remainder of design tasks to be completed, bid and award,
equipment delivery (if long lead time), and construction schedule. Long lead items
will be identified for possible pre-purchase.
Task 1 Assumptions:
• Duration of design phase for this Task Order assumed to be 6-7 months.
Task 1 Deliverables:
• Opinions of Probable Cost (at Preliminary and 90% design submittals)
• Estimated Project Schedule (at Preliminary and 90% design submittals}
Task 2-Preliminary Design of Reservoir and Booster Pump
Station
2.1 Site Visit
CH2M HILL will conduct one site visit to take photographs of the existing site and to
generally become familiar with the site and topography. CH2M HILL will rely on the
City for any as-built information regarding buried utilities.
2.2 Hydraulic System Modeling Coordination
It is our understanding that the City will perform all necessary hydraulic modeling
required. CH2M HILL will coordinate with City personnel regarding the system
11 MAY 201o PAGE 3 OF '[5
hydraulic parameters that will be needed in order to complete the remaining
subtasks listed below. These parameters are expected will include, but may not
necessarily be limited to, the following:
• Maximum and minimum reservoir filling rate
• Maximum reservoir drafting rate
• Desired normal operational water level in the reservoir
• Minimum water level in the reservoir during maximum demand
• Overflow elevation
• Turnover rate of reservoir during average demand
• Pumping pressures and flow rates
• Pressure zone boundaries
• Operational preferences on pump configuration and sizes
CH2M HILL will coordinate with the Nampa & Meridian Irrigation District regarding a
permit for a discharge to Ten Mile Creek on the proposed site. It is our
understanding that the discharge will be used only for pump-to-waste flows and for
emergency overflow ftom the reservoir.
2.3 Prepare Preliminary Drawings and Specification List
CH2M HILL will prepare a preliminary site plan showing the approximate location
and size of the reservoir and booster pump station. The site plan will also show
preliminary design concepts for major distribution and supply piping and major site
construction features such as access road, sidewalks, fencing, and pedestrian path.
A preliminary floor plan of the booster pump station will also be prepared showing
the schematic layout of major mechanical equipment and piping components.
CH2M HILL will prepare a preliminary fist of specifications that will be used for the
final design of the reservoir and pump station.
2.4 Project Meetings
Following the City's review the deliverables for Task 2, CH2M HILL will participate in
a project review meeting with the City to discuss the recommendations made in the
preliminary design deliverables and the City's review comments. This project review
meeting will form the basis of understanding for the final design effort for the project.
All key decisions regarding site layout, facility layout, and major equipment are
expected to be confirmed before or during this project review meeting.
Task 2 Assumptions:
• A maximum of 2 CH2M HILL personnel will attend the site visit.
• Up to 2 CH2M HILL personnel will attend the project review meeting.
• The reservoir will be constructed of welded steel; no additional analyses
will be conducted for alternate tank materials.
• CH2M HILL will not be in attendance at public outreach meetings.
• The deliverable document for Task 2 may precede the deliverables for
Task 5 in order to meet the overall design schedule desired by the City.
Task 2 Deliverables:
11 MAY 2010 PAGE 4 OF 15
• Preliminary drawings and project specifications list
• Project review meeting notes in electronic format
Task 3-Geotechnical Site Evaluation
CH2M HILL wilt perform a geotechnical site exploration to gather site-specific
subsurface information and collect soil samples for classification and laboratory
testing. The field exploration at the site will consist of two shallow soil borings and
one deeper soil boring. The shallow borings will be advanced, one each, at the
anticipated reservoir location and at the anticipated booster pump station location.
The deeper boring will be advanced at the anticipated reservoir location. The
shallow soil borings will be advanced using hollow-stem auger drilling methods, to
auger refusal or to a depth of approximately 15 feet, whichever is shallower. The
deeper soil boring will be advanced using hollow-stem auger drilling methods, to
auger refusal or to a depth of approximately 40 feet, whichever is shallower. It is
assumed that all of the boring locations can be acxessed by atruck-mounted drilling
rig.
Standard Penetration Testing and split-spoon soil sampling will be performed at 2.5-
foot intervals to a depth of 10 feet, and at 5-foot intervals thereafter, in order to
evaluate the soil relative density and consistency. A CH2M HILL geotechnical
engineer or engineering geologist will oversee the work of a subcontracted driller,
will log the borings, and will make field characterizations ofthe samples. If ground
wa#er is encountered in any of the borings, the depth to the water surface will be
noted in the field logs.
A limited laboratory testing program will be performed on collected soil samples in
order to evaluate index properties of the soil. If rock is encountered within the depth
of the proposed construction, or if very weak or problematic soils are encountered,
additional testing may be recommended (at additional cost).
CH2M HILL will perform engineering analysis to develop recommendations for site
seismic classification, presumptive allowable bearing pressures, lateral earth
pressures, and construction issues. A brief geotechnical engineering technical
memorandum will be prepared for internal CH2M HILL use in designing the facilities
on site. Final borehole and test pi# logs and an exploration location plan will be
included in the report.
If additional rock coring or laboratory testing is recommended based on actual
subsurface conditions encountered, authorization will be sought prior to performing
either of these activities.
Task 3 Assumptions:
• In subsurface investigations, the actual characteristics may vary
significantly between successive test points and sample intervals and at
locations other than where observations, explorations, and investigations
are made. Because of the inherent uncertainties in subsurface
evaluations, changed or unanticipated underground conditions may occur
that could affect total project cost or execution. If conditions change that
11 MAY 2010 PAGE 5 OF 15
require additional exploration and analysis, the scope and budget will be
adjusted by amendment to add these additional services.
• Installation of a test well or monitoring well is not included in this scope of
work.
Task 3 Deliverables: None
Task 4^.Site Survey
4.1 Topographic Survey of Reservoir and Pump Station Site
CH2M HILL will contract with Critigen to perform a field survey of the proposed site
in order to determine existing field conditions, including surface features, non-buried
utilities, and utilities marked by Idaho DigLine. The final internal product of the site
survey will be a digital terrain mode[ (DTM) and a site base map with 1-foot
contours. Horizontal and vertical control locations of the proposed geotechnical
exploration points (borings} will be collected, and these locations will be staked so
that the adjacent buried utilities can be marked by Idaho DigLine for buried prior to
drilling operations.
4.2 Topographic Survey of Ten Mile Creek
CH2M HILL will contract with Critigen to perform a survey of the adjacent Ten Mile
Creek in order to obtain the data necessary to complete the flood modeling effort
described in Task 5. The survey will provide a maximum of 11 creek cross sections
that will be used in conjunction with the site base map described in the previous
subtask.
Task 4 Assumptions:
• The site survey will be performed using real-time kinetic (RTK) global
positioning system {GPS) equipment.
• A maximum of 4 control points will be set or identified for construction
survey control.
• The site survey will be limited to the area of approximately 4.0 acres (the
limits of the proposed property), with the following exceptions:
• The cross section of Ten Mile Creek will be surveyed along a
maximum of 11 distinct lines extending away from the creek centerline
in both directions to the approximate extents of the 500-year flood
plain, along with bridge and culvert geometry at South Locust Grove
Road.
• The site survey will be tied into at least two existing FEMA reference
markers
• Underground utilities will be located by Idaho DigLine prior to the survey.
• CH2M HILL cannot be held responsible for non-performance,
inaccuracies, or omissions of Idaho DigLine utility locates.
Task 4 Deliverables: The site base map will be made available to the City upon
request.
11 MAY 2010 PAGE 6 OF 15
Task 5-Ten Mile Creek Flood Analysis and Modeling
The proposed location of the reservoir and booster pump station is located in the
floodplain of Ten Mile Creek (see Exhibit 1). Potential flood impacts associated with
the reservoir and pump station will be assessed using standard flood analysis and
modeling. As part of the flood analysis, hydraulic models will be produced using
existing data to be furnished by FEMA or the City of Meridian, limited site-specific
topographic information, and direct communication with Meridian (and potentially
Ada County).

Results from the flood analysis will be summarized in a brief technical memorandum
(TM) that will be used to iteratively guide the reservoir design. The technical
memorandum will contain the basic hydraulic information that might u~imately be
required by Meridian and FEMA to initiate revision of the flood boundaries (map
revision) shown in the flood insurance rate map (FIRM).
After the project has been constructed, CH2M HILL anticipates the City of Meridian
may be required by FEMA to request a map revision by submitting a Letter of Map
Revision (LOMR). Consisten# with the City's request that services during
construction be included in subsequent phases of work, preparing the LOMR that
would rely on post-construction as-built data is beyond the scope of services of this
agreement. However, CH2M HILL can provide such services during a future task
order as requested by the City.
5.1 Obtain and Evaluate FEMA Effective Model to Establish a Corrected
Effective Model
CH2M HILL will obtain and review the current Effective Model provided by FEMA. The
Effective Model is assumed to be the HEC-RAS model revised to reflect the LOMR effective
11 MAY 2010 PAGE 7 OF 15
July 7, 2008 as indicated on the FEMA website. Results from the Effective Model will be
compared to published Base Flood Elevations (BFE's} to ensure that the LOMR was
recorded properly and is consistent with city and county floodplain administrator records.
Hydrologic and hydraulic modeling parameters will be checked for accuracy and
consistency with published values in the Flood Insurance Study {FIS} and
documentation associated with the LOMR effective July 7, 2008. Necessary
changes will be applied to the Duplicate Effective model and this resulting model will
be considered the Corrected Effective Model. If results match within 0.1 feet, the
mode! will be considered a Duplicate Effective model. If any discrepancies greater
than 0.1 #eet are noted, CH2M HILL will discuss the noted discrepancies with the
City and the Ada County floodplain administrator and establish a plan for addressing
the noted differences to develop a Corrected Effective Model.
5.2 Collect Existing Conditions Data
So that the Effective Model accurately reflects topographic and structural
information specific to the project site, additional topographic survey data will be
collected. Spec~cally, the following cross-section and structural data will be
collected as a sub-task to the larger site topographic survey {see also subtask 4.2):
• Up to 2cross-sections upstream from the property.
• Up to 5cross-sections within the property.
• Up to 3cross-sections downstream from the property.
• 1 culvert (South Locust Grove) downstream ftom the property.
Given the published FEMA maps, it appears that effective cross-sections are
located upstream and downstream from the project site, so no additional cross-
sections (beyond the number listed above) will be collected ftom those areas so that
modifications to the Effective Model are minimized.
5.3 Create HEC-IRAs Existing Conditions Model
CH2M HILL will update the Corrected Effective Model to reflect current conditions
using the topographic survey data gathered as part of Task 4. Spec~cally,
CH2M HILL will update cross section information and/or culvert dimensions that are
collected as part of the topographic survey collection effort.
5.4 Create HEC-IRAs Proposed Conditions Model
CH2M HILL will update the Existing Conditions Model to reflect proposed site
conditions. Up to three Proposed Conditions Models will be developed. Specifically,
CH2M HILL will modify the existing conditions digital terrain model (DTM) to
represent grading changes associated with the proposed development of the
reservoir and booster pump station. The existing DTM model and site map will be
generated as a part of Task 4. The Proposed Conditions Models will include two
different scenarios reflecting different on-site modifications. The scenarios are
summarized below:
• Scenario 1 - On-site re-contouring with no changes to the South Locust Grove
Road culvert.
11 MAY 2010 PAGE 8 OF 15
• Scenario 2 - On-site re-contouring with larger capacity box culvert (or similar
structure to be determined) at South Locust Grove Road.
Grading concepts may include primarily floodplain re-contouring to increase
conveyance to the extent that construction of the proposed reservoir and pump
station results in no or minimal changes to BFEs. As such, grading or proposed
changes to the channel or banks will not be performed unless necessary to
complete the reservoir and booster pump station project. If it is determined that
revisions to the channel or banks are necessary, CH2M HILL will discuss the
findings with the City and establish a plan for addressing the issue. Addressing
revisions to the channel alignment or profile are considered beyond the scope of
services of this agreement.
Results from the flood analysis will be summarized in the technical memorandum.
The memo will summarize the model results ftom the Effective and Existing
Conditions models, as well as the preferred Proposed Conditions scenario. A figure
depicting the 100-year, and 500-year floodplain boundaries for the preferred
proposed conditions scenario will also be included.
5.5 Flood Analysis Stakeholder Facilitation
CH2M HILL has assumed that the City will take the leadership role to coordinate
with various stakeholders regarding the flood analysis results and potential impacts.
Such stakeholders may include Ada County, FEMA, and other City departments.
CH2M HILL will not be providing stakeholder facilitation services under this subtask.
Task 5 Assumptions:
• Ada County may need to jointly review this hydraulic study project
because the applicant is the City of Meridian.
• There is an existing, accessible HEC-RAS model that FEMA relied on to
publish the FIRM.
• There are existing, accessible HEC-RAS models that formed the basis of
the 2008 and 2008 LOMR's in the project vicinity. These models can be
spliced into the FEMA HEC-RAS model with minimal complication.
• The City will provide guidance for the design and construction of a
pedestrian path as it relates to site grading and floodplain grading for the
Proposed Conditions model.
• Meridian's Floodplain Development Permit will be administered internally
outside of this scope of services.
• Task 5 Deliverables:
• Flood analysis technical memorandum (final hydraulic report and work
map can be provided under a subsequent task order if required for City
documentation or for if a FEMA LOMR is required).
11 MAY 2010 PAGE 9 OF 15
Task 6-Final Design
6.1 Preliminary Engineering Report
A Preliminary Engineering Report summarizing the preliminary design effort will be
prepared in accordance with IDAPA 58.01.08, Idaho Rules for Public Drinking Water
Systems, and submitted to IDEA. The report will reflect any key decisions made at
the project review meeting at the conclusion of Task 2. The Preliminary Engineering
Report may include the following sections:
• Existing System
• Location
• Size
• Water Quantity
• Storage
• Operating Pressure
• Hydraulic Analysis
• Sources of Water
• Sewage
• Treatment Wastes
• Monitoring Results
• Community Systems
• Potential Contamination
• Flooding
• Additionallnformation
It is noted that not all of the above sections will be applicable to this project, and will
be characterized as such in the report. Furthermore, some of the sections will simply
refer to the City's water master plan for applicable information.
CH2MHILL will submit the draft report to the City and to IDEQ Boise Regional Office
for review and approval.
6.2 80°~ Design Documents Preparation
CH2M HILL will advance the design of the project and will incorporate comments
from the City from the previous Subtask in order to produce approximately 90%
complete drawings and specifications. A project review meeting will be held
following the City's review of these documents, as outlined in Subtask 6.4.
6.3 Final Fix-up and Contract Documents Preparation
CH2M HILL will provide final fix-up of the drawings and specifications based on the
City's comments from the previous Subtask. Bid documents, in the form of and one
set of electronic files and 4 sets of printed documents (drawings printed at half-size),
will be delivered to the City. Electronic bid documents will be delivered in Portable
Document Format (PDF).
11 MAY 2010 PAGE 10 OF 15
6.4 Project Review Meetings
Four copies of 90% complete project documents will be provided for the City's
review and comment. A project review meeting will be conducted following the City's

Task 6 Assumptions:
• Prior to the start of the final design task, the City will provide CH2M HILL
with all information available on existing utilities located on the proposed
site.
• The City will annex the property; all design will be performed according to
City planning and zoning requirements (not Ada County requirements).
• The City will coordinate al! of the requirements and commen#s from
internal City departments and division (Parks and Recreation, Planning
and Zoning, etc.) and provide such requirements and comments to CH2M
HILL.
• The City will perform all necessary coordination with Nampa & Meridian
Irrigation District and will pay directly for any license agreement fees
related to the project.
• The City will provide CH2M HILL with the manufacturer's name and model
for the required remote terminal unit (RTU} to be used for the City's
SCADA system. CH2M HILL will specify the requested RTU and will show
controls wiring terminating at this location. The City will contract
separately with a third party to program the system after the contractor
has installed all necessary systems and wiring.
• The new pedestrian and bicycle bike path will be located on the north side
of Ten Mile Creek and the limits of the design will be from the east side of
South Locust Grove Road to the east property boundary.
• Design of a new, enlarged culvert at South Locust Grove Road is not
included in this scope of work. However, if the flood analysis indicates that
a larger culvert would be an effective flood mitigation option, the scope
and budget for the design of a new culvert could be added by amendment
to include this task at the City's request.
• CH2M HILL will show locations of wetlands and other sensitive areas on
the final site plan. The selected contractor will be responsible for
preparing the storm water pollution prevention plan (SWPPP} and for
determining necessary measures to protect the ident~ed sensitive areas.
• Since all key decisions regarding site and facility layou#, materials of
construction, and major equipment will be confirmed at the time of the
preliminary design submittal, it is assumed that comments received from
the City on the 90% submittal will be of a minor nature that will not require
significant redesign.
• Technical spec cations will be based on CH2M HILL master
specifications, conforming to Construction Specification Institute (CSI)
MasterFormat 2004 (49-division format).
• Drawings will be prepared in Microstation using CH2M HILL CAD
standards.
11 MAY 2010 PAGE 12 OF 15
• City will provide compiled written comments on the 90% design submittal
in a timely manner.
• City will file all required permit applications and pay any associated fees.
• This scope of work is for the outlined design services only. Services
during the bid period and engineering services during construction
(submittal review, responding to RFl's, construction observations, record
drawings, etc.) will be included in a separate task order.
Task fi Deliverables:
• One electronic copy (PDF) and four printed copies of the Preliminary
Engineering Report, delivered to both the City and IDEA
• One electronic copy (PDF} and four printed copies of the 90% drawings
and specifications
• Meeting notes from 90% project review meeting, delivered in electronic
format
• One electronic copy (PDF) and four printed copies of final bid set
drawings and specifications, delivered #o both the City and IDEA
