RECOMMENDED ACTION: Motion to Authorize Signatures on Letter of Engagement for
Task 2 of County Road 42 & Blaine Avenue Trunk Watermain and Pressure Reduction
Valve Relocation Project
BACKGROUND
In support of pending large-scale development activity in the County State Aid Highway 42 (CSAH 42)
corridor, City staff have been working with engineering consultant Short Elliot Hendrickson (SEH) since
fall of 2022 on a preliminary design for the construction of a project to extend trunk watermains in key
locations between Akron Avenue and US Highway 52 as well as on Blaine Avenue. Attached is a map
identifying the project features.
The attached letter of engagement previously authorized SEH to perform the preliminary design work
(Task 1) as described in the attached work scope. With Task 1 soon reaching completion, the next step of
preparing the final design and bid documents is warranted (Task 2). Moving forward with Task 2 to
prepare final design plans and bidding documents requires additional authorization from the Council.
One of the parties considering locating on the corridor desires the City to continue to work on this
accelerated approach to infrastructure delivery and had entered into an agreement with the City in the fall
of 2022 which required deposits of escrowed funds by the prospective developer as a means of covering
the costs of the project development work. Once the City and SEH are ready to proceed with carrying on
to the next stage of this project, the City will be requesting additional escrow deposits from the developer
before commencement of Task 2 activities, which are estimated to cost approximately $116,000. Staff will
return to the Council to request authorization for Task 3 to put the project out for bids and perform
construction project management in the event that we have firm commitment that the developments in
the CSAH 42 corridor will be moving ahead with their construction, which we anticipate we will learn this
coming spring.
Provided the pending large-scale development projects begin in 2023, staff anticipates the start of
construction for the trunk watermain work to begin in fall of 2023 or spring of 2024.
RECOMMENDATION
Staff recommends the City Council authorize the Mayor, City Clerk, and Public Works Director to affix
their signatures on the attached Letter of Engagement enabling Task 2 to proceed as described in the
attached work scope.

September 12, 2022 RE: Proposal for Professional Design Services
CSAH 42 Trunk Watermain Extension
SEH No. ROSEM P-166432 14.00
Mr. Nick Egger
City Engineer
City of Rosemount
2875 145th Street West
Rosemount, MN 55068
Dear Mr. Egger:
The City of Rosemount is proposing to construct an extension to their existing 16” water main located on 145th
Street E (CSAH 42). This new pipeline segment is basically proposed to extend from the pressure reducing
valve (PRV) across from the Dakota County Technical College (DCTC) to the existing 16” water main located
west of US Highway 52. An additional water main extension is proposed from 145th St W north to 140th St E.
The purpose of this extension it to provide water service and fire protection to proposed developments on
UMore property located east of DCTC.
To assist the City with this endeavor, Short Elliott Hendrickson Inc. (SEH®) is pleased to provide this proposal
to provide engineering services for the design and construction of this water main extension. This project will
result in critical improvements to the existing water infrastructure to serve increasing water demand and the
need for water treatment. Our team has identified the following aspects of the project that will be key to its
success:
x Coordination with the City of Rosemount and Dakota County.
x An early assessment of pipeline route that will review existing right-of-way space and the locations and
impacts of public and private utilities to avoid potential project delays.
x Providing clear project management to meet deadlines and scheduling of the work to happen in the 2023
construction season.
x Minimizing disturbed areas by utilizing methods of trenchless utility installation where feasible.
Short Elliott Hendrickson Inc. (SEH®) has intentionally formed our team to provide the right experience and
technical knowledge to address these critical success factors and make this water systems connection project
a success. This proposal is based on conversations with City staff, a project drive through and our knowledge
of similar projects. We are confident the team and approach outlined here will lead to smooth project delivery.
PROJECT UNDERSTANDING
The City of Rosemount is proactively planning to construct an extension of their existing 16” water main on
CSAH 42 and Blaine Avenue so that water service and fire protection is available to development projects
proposed for the UMore property east of DCTC. Based on preliminary information provided to the City from
the property developers, the 16” main is needed to provide the service capacity required.
There are many technical and procedural challenges associated with this project that will need to be
addressed:
x Providing timely coordination and meeting design standards required to obtain necessary permits
Mr. Nick Egger
September 12, 2022

x Communicating with adjacent property owners, Met Council and Dakota County
x Working within the Dakota County right-of-way limiting impacts CSAH 42.
x Identifying, evaluating, and determining solutions for trenchless utility design based on Geotechnical
findings
x Coordinating with utility companies to identify potential conflicts and resolutions
Extending the water main east on CSAH 42 and north on Blaine Avenue will require review and evaluation of
the available right-of-way space on both sides of either corridor. Currently, it is preferred to extend the water
amin along the south side of the road, but further investigation is appropriately needed.
Along with this project, the City is proposing to relocate the PRV station to the 16” water main on Bonaire Path
east of Blaine Avenue. Currently, the existing water main on Bonaire Path is on the City’s low-pressure
system. Relocation of the PRV will boost pressure on that water main and allow the City to provide redundant
service capacity to the proposed UMore developments
This full design must incorporate AWWA standards, CEAM design standards and City of Rosemount
standards.
PROJECT APPROACH
Task 1: Data Collection & Preliminary Design
Topographic Survey & Soil Borings
A survey will be performed in the project area to establish a base map file for understanding the existing
conditions in the field. This work will be performed following an approved alignment for the proposed water
main to gather topographic data along the proposed route. The schedule is dependent upon accurate surveys
as soon as reduced snow cover permits.
A good foundation is key to every successful project. SEH’s senior Geotechnical Engineer, Luke Thompson,
PE will lead the team in obtaining the needed geotechnical information for the project. He will develop site
stratigraphy and soil parameters, evaluate fill areas and soil corrections, evaluate utility bedding, and prepare
the geotechnical report. Luke and his team will also assist in plan and specification creation and cost
estimation. SEH will contract directly with a geotechnical testing firm for obtaining soil borings on the project.
We have included an allowance of $60,000 for hiring a subcontractor to perform the soil borings and testing to
determine soil characteristics. Given the many unknown variables involved with the presence of existing
utilities in the boulevard area along the anticipated water main alignment, the drilling may need to occur in the
roadway during off-peak traffic hours. Sufficient geotechnical investigation is crucial to the design elements of
trenchless installation and the structural support of the proposed infrastructure.
Utility Coordination
A design can only be as good as the information that you have available. With that in mind, the SEH Team will
coordinate with Gopher State One Call for locating of existing utilities and coordinate with the surveyors to
locate all marked locations with a topographic survey of the proposed project area. The team will also use their
expertise to lay out the right-of-way boundary and adjacent properties for the project area. This information will
be essential for creating an accurate base map file and Digital Terrain Model.
Early identification of potential conflicts or utility improvement needs and ongoing coordination with the public
and private utility companies are key components for a smooth-running project. The SEH team proposes to
meet with the utility companies at the start of the project (after the topographic survey and existing water main
locating performed by the City of Rosemount but prior to preliminary design). This is proposed for two
purposes: to inform the utilities of the proposed project and to gather the most accurate information from them
about the existing utilities, and to verify all utilities captured by our topographic survey. We also propose to
hold a second meeting once the final layout has been chosen to discuss any conflicts and coordinate potential
relocations. Additional time for coordination has been included in the proposal for potential coordination with
affected utilities.

Preliminary Water Main Design & Value Engineering
It is important to note that the design of the water main is greatly dependent on existing utility locations and
available right-of-way and/or easements. Our team will identify a design approach that best serves the City
and its relations with Dakota County Highway Department. The design of the water main is anticipated to be a
combination of open-cut installation and trenchless installation to limit impacts to 145th Street (CSAH 42),
Blaine Avenue, and existing in-place utilities. Our team will analyze the costs of such proposed installations to
determine which methods are the best economical and practical approach.
Task 2: Final Design & Bid Documents
Final Design
After the preliminary layout of the proposed water main is complete, the SEH Team will move onto final design
of the proposed improvements to meet the deadline of bidding this project in December 2022. The chosen
installation approach of the water main will be designed to meet the AWWA, MDH and City of Rosemount
standards. This will include design of impacted infrastructure such as driveways, sanitary sewer, private
utilities, and miscellaneous restoration items.
Bidding Documents & Bidding
SEH will prepare the project specifications and bidding package, and the project can be advertised once City
Council approval of the plans has been completed. SEH’s project manager and technical experts will be
available throughout the bidding process for questions. We will attend the bid opening and analyze the bids in
order to give a contract award recommendation to the City.
SEH will provide all project base files to the City in AutoCAD Civil 3D as well as all digital plan sheets.
Task 3: Construction Services
Construction Observation & Documentation
Ensuring the valuable new asset of the City of Rosemount is installed to City expectations industry standards
outlined in the project documents, our experienced team and resident project representative (RPR) will
administer and observe the construction of this project. Our team members are experienced with complex
trenchless installations and similar utility construction projects. Proper planning and communication in the field
leads to a successful construction project.
Construction Staking
Our local survey team will assist in providing accurate staking locations utility improvements for the contractor
to build the proposed design. SEH will also assist in documenting locations of critical new infrastructure and
providing accurate record drawings.
Value Added Services
The SEH team has additional services that could be utilized for this project. Some of these services include
retaining wall design, water quality basin design, stormwater permitting, lighting design, MnDNR utility crossing
licensing, MnDNR public waters work permitting and easement acquisition. If these services are needed, there
is value added to the City of Rosemount as our team will already be knowledgeable in the project and can
incorporate these services at a reasonable cost.
