RECOMMENDED ACTION: Motion to Approve SEH Inc. Proposal for Engineering
Services for Rosemount Comprehensive Water Plan Update
BACKGROUND
The City of Rosemount is currently updating its Comprehensive Plan. As part of that update various
sections of the plan require individual updates. Staff has requested proposal from several firms in the
engineering pool for these updates.
The Comprehensive Water Plan Update proposal from SEH Inc. consists of two separate tasks.
•Task 1 focuses on the required items for the Comprehensive Plan. A review of the land use and
existing system studies along with population projections and water demand will provide a
foundation for future water system recommendations. Total cost is $25,582.
•Task 2 provides the detailed engineering analysis to establish a long range water system master
plan. This includes updating and calibrating the water system model to establish future capital
needs along with cost estimates. Total cost is $29,412.
The total cost of the proposal is $55,000; however, staff recommends that award of Task 2 be delayed,
pending further discussion. As a result the total cost would be for Task 1 only ($25,582). The current
water utility budget has $15,000 for the update to the comprehensive plan. In addition, there is a budget
item of $55,000 for a water facility study, and staff recommends that the additional $10,582 for Task 1
come from this budget line.
SUMMARY
Staff is recommending approval of the attached Engineering Services Proposal from SEH Inc. for Task 1
only. If needed, staff will return with Task 2 for Council approval at a later date.

Dear Brian:
Short Elliott Hendrickson Inc. (SEH®) appreciates the opportunity to submit this proposal to the City of
Rosemount for updating the Water Supply Chapter of the City’s 2040 Comprehensive Plan as required by
the Metropolitan Council. The City’s Comprehensive Plan is part of a long-range planning document for
future development of Rosemount and the regional metropolitan area. The Comprehensive Plan will
identify the City’s goals and objectives for land use, housing, transportation, wastewater and water supply
services, surface water, and natural environment including parks and open spaces.
WORK PLAN
Our proposed work plan for this project is divided into two (2) parts. Part 1 prepares an update to the
City’s existing water system plan that more than satisfies the framework of the Met Council’s
requirements for the Water Chapter of the 2040 Comp Plan. Part 2 provides an update and recalibration
of the City’s water distribution system model and subsequent updates to the current capital improvement
plan.
The City’s October 2016 MNDNR Water Supply Plan fulfills most of the minimum Met Council
requirements for the Water Chapter of the 2040 Comprehensive Plan. However, the MNDNR Water
Supply Plan “template” document does not lend itself to serve as a readable chapter that can merely be
inserted into the City’s Comprehensive Plan. More importantly, the MNDNR Water Supply Plan does not
fully address “triggers” that will help the City of Rosemount determine how to phase water supply,
treatment and storage improvements as development progresses, and as water quality issues and
regulations continue to evolve. Prior work has begun to set the framework for this phasing discussion.
Part 1 of our Work Plan provides a means to combine the prior water system planning work, and update
the recommendations based on current operational strategies and Land Use decisions.
Although not strictly necessary for the 2040 Comp Plan update, Part 2 of our work plan provides a new
Water System Master Plan for the City. This work includes an overhaul and update of the City’s water
system model and utilizes the model to determine future water supply, storage, and distribution system
improvements. Maintaining an updated and calibrated water system hydraulic model is essential for
answering those “what if” questions of pipe sizing, pipe routing, and supply/storage phasing as new
development or redevelopment projects arise. The City’s existing model will be updated to include pipes
and facilities added (based on the City’s GIS database) and will apply historic water billing records for
accurate water use and distribution across the modeled network of pipes. The resulting model and
City of Rosemount

hydraulic analysis will provide a basis for comprehensive planning documents and update the water
model for up and coming localized water main replacement projects. The model will continue to be a
useful design and decision making tool.
Part 1 – Water Chapter Framework
The goal of this first part is to collect, review and update background information on the water system,
and to determine appropriate design guidelines for implementing water system improvements. The work
of Part 1 becomes the framework for the Water Chapter of the 2040 Local Comprehensive Plan.
Task 1.1 – Review Land Use, Population Projections and Water Demand Projections
Since the SEH project team is already familiar with the water system and the goals of the City of
Rosemount for this planning cycle, we can begin work immediately. We will prepare a memorandum
requesting existing relevant data for review. Pertinent data includes recent water usage records, geo-
coded water billing records, recent ISO reports, up to data GIS files of the water system, GIS files of
existing land use, zoning, proposed land use, and developable/re-developable parcels, population
projections, as well as the City’s October 2016 MNDNR Water Supply Plan. It is anticipated that the City
will solicit input on Land Use and population projections from City Planning, and that no additional
meetings with the City are required.
Task 1.2 – Water Supply, Treatment, and Storage Review
The City of Rosemount water supply, storage, and distribution systems generally provide adequate
service to all customers. The City has numerous water system planning documents and memos
addressing various aspects of the water system. We will review these documents and update the
recommendations in light of the most current existing and proposed water quality standards and
development plans. Specific emphasis will be given to the phased implementation of water treatment,
should treatment be deemed necessary.
General design criteria will be established for supply, treatment, storage, and distribution system
improvements, and documented in the resulting Technical Memo. Detailed hydraulic analysis of the
distribution system will be performed in Task 2, however, for the purposes of this Task, specific design
criteria will be established for fire flows, pressures, and desired supply/storage balance.
Task 1.3 – Meetings and Technical Memorandum
Since the results of Tasks 1.1 and 1.2 impact the remainder of the project, each sub-task will be reviewed
in detail with the City prior to moving to the next task or sub-task.
The resultant Technical Memos, with City comments will provide the basis for the City to prepare their
Water Supply Chapter of the Comprehensive Plan.
Part 2 – Water System Master Plan
The goal of the second part of this project is to provide the detailed engineering background and analysis
needed to establish a long-range water system master plan. This work includes detailed hydraulic
modeling of the water system, phasing analysis, and detailed cost estimates required for the City’s
Capital Improvement Plan and Trunk Utility Charge System. The work of Part 2 picks up where Part 1
ended and moves forward in preparing a new Water System Master Plan.
Task 2.1 – Hydraulic Model, Existing and Future System Analysis
The City’s hydraulic water system model can be a powerful tool for analyzing “what if” scenarios
associated with development. To serve as such, the model must be updated. The work of this task will be
to updated, calibrate, and then utilize the model for analysis of the adequacy of the existing and proposed
water system.
We will work with the City to carry out field hydrant flow testing to accomplish calibration and verification
of the water model. This work provides an opportunity to update the model with field data to create a
City of Rosemount
March 28, 2018
Page 3
model that reasonably represents actual system performance and provides confidence in the water model
results.
The calibrated hydraulic model is then used to determine adequacy of the system during average day,
maximum day, and fire flow events. For this analysis, existing fire flows will be compared to the required
fire flows based on land use and zoning, and as determined from the local building official.
The hydraulic model will be used to re-evaluate potential solutions for the deficiencies discovered in the
above tasks. This effort will also evaluate means to adequately serve proposed development areas.
Furthermore, Maximum Day, Peak Hour, Tank Filling, and Fire Flow analysis will be performed for the
ultimate service area to determine the feasibility and need for additional piping to provide adequate
pressures and flows throughout the system. Trunk supply, treatment, storage and distribution
improvements will be provided for the system.
If requested, SEH can also utilize the model to analyze multiple phasing scenarios.
Separate technical memos and review meetings are providing for review of the calibration and existing
system results, and for review of the final Ultimate system results.
Task 2.2 – Final Report
An updated version of the comprehensive water plan report will be provided, which will include the
previously mentioned tasks in addition to including a summary of previous work.
If desired, this task could be expanded to provide the basis for updating the City’s Trunk Water charge
system.
We have assumed one final meeting to assist City staff in presenting this Report.
PROJECT SCHEDULE
SEH has the staff available to begin the project as soon as the City of Rosemount presents a notice to
proceed on the project. We understand that the projected land use has been established.
CONSULTANT STAFF
For this project, SEH will utilize water system modeling expert Mark Wallis. Mark provided the modeling
for the East Side Utility Study. Project quality control and additional senior guidance will be provided by
Miles Jensen.
COMPENSATION
The enclosed task hour budget provides detail on our proposed level and distribution of effort for
completing the project. Compensation for our Part 1 - Water Chapter Framework for the Water Chapter
of the City’s 2040 Comprehensive Plan is proposed to be a not-to-exceed $25,582. Compensation for
our Part 2 - Water System Master Plan is proposed to be a not-to-exceed $29,412. The total for both
parts is $55,000.
Our fees include reimbursable expenses. We will invoice the City of Rosemount monthly on an hourly
basis for payment for our services. Monthly charges for services will include expenses.
GENERAL SERVICES AGREEMENT
This letter and the existing 2016 Professional Services Agreement between the City of Rosemount, MN
