Mr. Andy Brotzler, P.E.
Public Works Director/City Engineer
City of Prior Lake
4646 Dakota Street SE
Prior Lake, MN 55372
Re: Proposal for Professional Engineering Services – Feasibility Stage
Northwood Road Area Street & Utility Improvements Project
Dear Mr. Brotzler:
Thank you for the opportunity to submit this proposal to provide professional engineering services to the
City of Prior Lake for street and utility improvements to the Northwood Road area. Our team is well
equipped to deliver high quality services across the multiple phases of this project, ensuring compliance
with regulatory requirements, designing to city standards, and addressing the specific needs of the City.
Based on conversations and meetings with city staff, we understand that the City has this project
programmed in their Capital Improvement Program (CIP) for construction in two phases over the 2026 and
2027 construction seasons and is seeking professional engineering services to bring the project from
conception through construction. It is our understanding that the project area includes some street segments
that are state aid routes, however, state aid funds will not be utilized and the project will be funded
completely with local funds, which includes assessments from adjacent benefitting properties. The project
will follow the 429 statutory process to levy special assessments from benefiting properties, in accordance
with the City of Prior Lake’s assessment policy.
The project area is all zoned for single-family residential with a small area of park/recreation/preserve
towards the south end. The project will include improvements to Northwood Road NW, Butternut Circle
NW, Knollridge Drive NW, Knollridge Court NW, Hawk Ridge Court NW, Hawk Ridge Road NW,
Visionary Heights Circle NW, Tahinka Court NW, Tahinka Place NW, Viewcrest Circle NW, Lake Haven
Court NW, Shady Cove Point NW, Lake Bluff Circle NW, Island View Road NW, Island View Circle NW,
Island Circle NW, Fremont Avenue NW, Fremont Street NW, Fremont Circle NW, and Crystal Circle NW.
Based on existing pavement conditions, whether or not the street has existing concrete curb and gutter, and
existing subsurface utility conditions, some streets will be completely reconstructed while other streets will
be rehabilitated by means of a mill and overlay. A project area map is attached to this proposal which
identifies the assumed improvements for each street segment based on currently available information.
Streets identified for reconstruction total nearly 12,000 lineal feet and will, in general, include full
replacement of all public utilities (sanitary sewer, watermain, and storm sewer) and installation of a new
street section with base materials, concrete curb and gutter, and bituminous pavement. Non-standard cul-
de-sacs in the reconstruction area will be evaluated for improvements within the existing ROW. Existing
pedestrian facilities will also be replaced in kind and concrete driveway aprons meeting city standard will
be installed at the back of curb. Discussion on city policy will be necessary to determine how to address
replacement of non-standard, specialty driveway materials. The city’s comprehensive plan shows that
watermain within the project area ranges in diameter from 6-inches to 12-inches. The comprehensive plan
shows no planned increase in pipe sizes for either watermain or sanitary sewer. Improvements to existing

N:\Proposals\Prior Lake\2026-2027 Northwood Road Area Reconstruction 080224\_Proposal Files 0PP.P03840\Northwoods Area Improvements Proposal_R2.docx
storm sewer and incorporation of new storm sewer to serve the streets transitioning from rural to urban
street sections will be evaluated for incorporation into the construction plans.
Streets identified for mill and overlay total approximately 11,000 lineal feet and will, in general, include
rehabilitation of the existing street pavement by milling off the top layer of existing pavement and re-paving
with new bituminous pavement. This process will include considerations to re-instate the crown of the
roadway if there are areas of deficient crown. Fremont Street NW is identified as a “Future Thru Street”. It
is anticipated that the geometry of this dead end, and other non-standard cul-de-sacs, will remain the same
with the proposed M&O and there will be no segments of full curb replacement. Spot replacement of
existing concrete curb and gutter and sidewalks will be completed to correct settled/heaved or severely
cracked/deteriorated segments that inhibit proper operation. Existing pedestrian facilities will also include
replacement of all pedestrian ramps to upgrade to current ADA standards, if they are not currently
compliant. Minor spot utility repairs may also be completed if isolated areas in need of repair are identified
by city public works staff and all utility structures/castings (catch basins, manholes, and valve boxes) will
be adjusted with replacement of all deficient rings to meet the new pavement improvements.
The overall project area also includes three lift stations with forcemain to manage the sanitary sewer in the
area. We understand that no improvements are proposed to the lift station/forcemain located on Fremont
Avenue, just north of Island View Road. Minor rehabilitation, including Barney brackets and potentially
pumps, and full forcemain replacement is identified for the lift station located on Northwood Road, east of
Fremont Avenue, with the forcemain terminating just south of Lake Bluff Circle. No improvements are
proposed to the lift station itself located on Northwood Road, just southwest of Butternut Circle, however,
the forcemain that runs south to Center Road will require full replacement and the parking area at the lift
station will be expanded.
There are two additional specific improvements anticipated to be included with the project that aren’t
otherwise identified. The first is to evaluate potentially adding a new sidewalk along Fremont Avenue to
connect existing pedestrian facilities from Crystal Bay Lane to Northwood Road, as identified in the city’s
2040 Park & Trail System Plan. The second is incorporating improvements identified in the city’s Local
Surface Water Management Plan that are within the project area. In conversations with city staff, the project
will include completion of item 5.3.2 (Island View Culvert Replacement) and item 5.3.7 (Northwood Road
Wetland Outlet). The Island View Culvert Replacement was further evaluated in the Prior Lake Stormwater
Resilience Study project and identified upsizing the culvert under Fremont Road, just north of Island View
Road, to a 42-inch RCP culvert. The Northwood Road Wetland Outlet identifies improvements to the
pond/wetland outlet which runs under Northwood Road, just south of Linden Circle. The improvements
will provide an overflow structure with an improved skimmer to better maintain the water lev el and may
also include a carp grate installed in cooperation with the PLSLWD. WSB already has this area included in
their storm/surface water model for the City and city staff indicated WSB will utilize this existing model to
provide a recommendation for pipe/structure sizing and elevations. It is assumed that the watershed district
would provide all required details and information for the carp grate incorporation, if included.
The general improvements identified above only include street and utility improvements within the existing
street right-of-way (ROW). The city has indicated that all existing sanitary sewer located outside of the
street ROW (such as stretches of backyard sanitary sewer) will be rehabilitated by CIPP lining under a
separate project. It is assumed that the only work included with this project that will extend beyond the
existing street ROW, and not already identified above, includes the evaluation of existing backyard
watermain replacement, east of Northwood Road approximately from Linden Circle to east of the Fremont
Avenue intersection. For the purposes of this proposal, we are assuming that watermain rehabilitation
methods (such as pressure CIPP lining) will be evaluated and incorporated, if feasible. Otherwise watermain
will be installed within the Northwood Road street ROW with new water service stubs to each property
served by the segment of backyard watermain for future connections.

Bolton & Menk has extensive experience in providing water resources engineering services and is
committed to delivering a design that meets all regulatory requirements while providing sustainable and
cost-effective solutions. Our team will ensure compliance with the MS4 general permit; meet the
requirements of the PLSLWD, MNDNR, FEMA, and other governing authorities; adhere to the City of
Prior Lake's design standards; implement sustainable water management practices; and provide a cost-
effective and efficient design within the constraints of the project.
Given the existing layout of the neighborhood and its proximity to Upper Prior Lake, many of the project
streets only have one way in and one way out. This will make access difficult during construction and will
require extensive evaluation of how the project is split between the construction years, and even
construction phasing for each project year to best maintain access. That being said, we also need to
communicate realistic expectations for construction which will not allow for access at all times. The City
has been a proponent of investing in enhanced communication and public engagement services for these
types of projects. Bolton & Menk has experience in the city’s expectations for public engagement and
understand that due to the complexities associated with this project, construction communication services
may need to be enhanced even further to make for a successful project.
Brad Fisher will serve as your project manager who will direct the project team and verify conformance of
the plans and specifications with the project requirements. This scope and fee letter identifies the various
project tasks and lists each task’s scope of work and associated fee to bring the project through preliminary
evaluation, design, bidding, and construction phases. A detailed work plan for each of the project tasks is
identified below.
This initial proposal will cover the feasibility stage of the project. It is our understanding that the city intends
to approve the professional engineering services in three stages: this initial feasibility stage, the design stage
for each project phase, and the construction stage for each project phase. This approach will significantly
reduce the number of assumptions made as to the scope of the project, prior to initial evaluations that will
better identify the project needs. The design and construction proposal amendments will be based on the
scope identified in the previous stage(s) of the project and modified to more accurately reflect the actual
project requirements and anticipated fees. The work plan for each project task identified below is only
reflective of what is necessary for the feasibility stage of the project. Each project task may have additional
work required during a later stage (design and/or construction) of the project. A draft work plan for all
anticipated project tasks, including design and construction stages, based on current assumptions regarding
the project scope is available upon request.
Task 1 – Project Management & Coordination Meetings
Work under this task includes conducting project meetings and overall project management to keep the
project on schedule and on budget. Anticipated project meetings, for the feasibility stage of the project, that
are included in our proposal are a project kickoff meeting with city staff, two feasibility study discussion
meetings, and attendance and/or presentation at one City Council Meeting. Meeting materials will be
provided for each meeting including agendas and meeting minutes for staff meetings and the
preconstruction meeting.
Task 2 – Topographic Survey
Work under this task includes gathering pertinent field information on city infrastructure, physical features
in the right-of-way, contours, and private utilities. Underground utility information will be located and
described per available as-builts, field markings, and private utility map information facilitated through
Gopher State One Call. Structure reports will be completed for located manholes and catch basins in the
reconstruction areas only. Structures will be located in mill and overlay areas but will not include structure
reports. Right-of-way and property lines will be illustrated based on either found field monumentation, plat

N:\Proposals\Prior Lake\2026-2027 Northwood Road Area Reconstruction 080224\_Proposal Files 0PP.P03840\Northwoods Area Improvements Proposal_R2.docx
information, and/or Scott County GIS parcel linework for reconstruct areas and along the potential new
sidewalk route on Fremont Avenue NW. All remaining mill and overlay areas will utilize Scott County GIS
parcel linework for right-of-way and property line depictions. Owner and Encumbrance Reports which will
include an easement search will only be requested for parcels within reconstruction areas that are either un-
platted properties or where roadway deviates from original underlying plat dedicated right-of-way. Property
corner monuments will be collected along the right-of-way of the reconstruction areas only, to aid in
determining right-of-way.
Full topographic survey will be completed for the proposed reconstruct project corridors and the potential
new sidewalk route to 10-feet beyond the ROW. Topographic survey will be completed from back of curb
to back of curb for the remaining proposed mill and overlay project corridors. Bolton & Menk will establish
horizontal control on Scott County coordinates NAD 83 (1996 Adjustment) together with vertical control
based on NAVD 88 datum. Control points will be placed at convenient locations throughout the project
corridor. We will generate a drafted survey base drawing which will include topographic and available
right-of-way survey information. It is currently unknown if there will be ROW impacts associated with the
project. We are assuming there may be a need for up to eight easement exhibits/descriptions for the project
for potential backyard watermain access and/or stormwater BMP pond expansions.
Topographic survey will be completed in the fall of 2024 as time allows considering construction staking
needs. It is assumed that the topographic survey can be completed prior to winter snowfall. If topographic
survey cannot be completed prior to snow/ice conditions that would hinder field collection, topographic
survey will be finished in the spring of 2025. Additional topographic survey beyond that identified above
can be negotiated at a fee based on submitted hourly rates.
Task 3 – Feasibility Study
Work under this task includes identifying proposed improvements, identifying issues or risks to the
project’s success requiring greater exploration during final design, and communication of these elements
to project stakeholders. We will deliver a feasibility report that discusses the existing conditions, the
research and analysis that was performed, the preliminary design features considered, the proposed
improvements, permitting requirements, project costs, financing, and recommendations. Work under this
task includes completing high-level preliminary design to determine if the project is necessary, feasible,
and cost-effective. The preliminary design will be completed based on actual survey information for the
reconstruction areas and the potential new sidewalk area to a base level necessary to identify potential
problem areas. The remainder of the mill and overlay project areas will be completed based on aerial
photography to roughly layout the proposed improvements in two dimensions.
The project is anticipated to utilize assessments to adjacent benefitting properties to fund a portion of the
street improvements on the project. The preliminary assessments will be calculated utilizing the identified
method in the City of Prior Lake’s assessment policy, which will require separate calculations for the
reconstruction areas and the mill and overlay areas, as well as separation between the anticipated project
phases (if they don’t directly align with the level of improvement). It is assumed that a special benefit
appraisal will not be required for the project.
As part of the feasibility study, we will analyze the possibility of adding a new sidewalk along the Fremont
Avenue mill and overlay corridor from Northwood Road to Crystal Bay Lane. It is assumed that all
reconstructed streets’ widths will be standardized but will generally match existing street widths. However,
all streets will include new concrete curb and gutter, regardless of whether it exists today or not. The
addition of new curb and gutter will require evaluation of associated new storm sewer improvements at low
points and to sufficiently manage spread. Some existing streets are narrow with steep embankments on each
side down to the lake which will limit the options for the new road layout. Along other reconstruction

N:\Proposals\Prior Lake\2026-2027 Northwood Road Area Reconstruction 080224\_Proposal Files 0PP.P03840\Northwoods Area Improvements Proposal_R2.docx
corridors, the need for street parking will be explored to determine if some streets can be narrowed to better
accommodate the intended improvements. The project is proposed to be constructed in two phases over
2026 and 2027. The feasibility study will investigate phasing limits to determine if the project will be split
between the reconstruct and mill and overlay project areas, or if another project split is more appropriate.
The goal is to identify the best project phasing to minimize disruptions and protect new infrastructure. The
feasibility study will be completed as one report for both projects but will continue after the feasibility stage
as two separate design and construction project.
Preliminary investigations into the National Wetlands Inventory (NWI), Public Waters Inventory (PWI),
and FEMA floodplains indicated these features are all within the vicinity of the project area. The feasibility
report will identify potential impacts to these features, issues to be considered and investigated further in
final design, and associated permitting required to construct the project. Additionally, the north portion of
the project area is identified to be within a wellhead protection area. Typically, stormwater infiltration is
not allowed within a wellhead protection area, but this assumption and any other associated requirements
related to the wellhead protection area will be further researched and identified. Prior Lake Spring Lake
Watershed District (PLSLWD) rules as they apply to the proposed project will be further investigated
during the feasibility study. However, it is anticipated that stormwater management rules will be triggered
and therefore, stormwater treatment and associated permitting will be required as part of the project.
Level II Wetland Delineation: Bolton & Menk will thoroughly investigate all available background
information needed prior to visiting the site. Based on the proposed activities, the wetland delineation
project area will encompass the street reconstruction, the street mill & overlay, the disturbance limits
associated with the culvert replacement, the disturbance limits associated with the forcemain replacement
and lift station parking, and the ponding areas located southeast of Knollridge Drive. A certified wetland
delineator will then visit the site to delineate all aquatic resource boundaries within these designated areas,
including the Ordinary High-Water Mark (OHWM) of the Mud Bay inlet. The delineation will include
performing transects and sampling in the vicinity of those wetlands, placing 3-foot pin flags at the limits of
any wetlands found. Our delineator will use a sub-meter GPS unit to accurately locate and map each point
and preparing a written report of our findings. Please note if it’s determined through the feasibility study
that additional wetland delineations are anticipated a supplementary scope and fee will be prepared for
those services.
Threatened and Endangered Species Review:
The anticipated aquatic resource permits will trigger State and Federal Threatened/Endangered species
review. To ensure the city is in compliance with Minnesota’s Endangered Species Statute and the federal
Endangered Species Act, Bolton & Menk will complete an NHIS request on the Minnesota Conservation
Explorer website early in the project process and will coordinate with MNDNR to be in compliance with
the current Minnesota Endangered Species Statute. The Information for Planning and Consultation (IPaC)
tool will be utilized later in the project process, during the permitting stage, to complete preliminary federal
threatened and endangered species coordination with USFWS. As long as the contract is awarded in time
to allow for tree clearing between November and April 15th, we are not anticipating significant restrictions
to the project’s construction (there just may be timeframes where certain areas cannot be worked on, such
as the lakes during spring for fish spawning). If any threatened and endangered species surveys are
required, we can provide an additional scope and fee at that time.
It has been identified that turtles may be near the project area and considerations may need to be
implemented into the project design to mitigate conflicts with turtles. This will be assessed during the
feasibility stage of the project to determine if design measures need to be considered with the project. The
recommendations will be evaluated further during final design for implementation but may include chain
link fences along ponds, as recommended by the Local Technical Assistance Program (LTAP), to control
turtle crossings and direct them to the appropriate locations.

N:\Proposals\Prior Lake\2026-2027 Northwood Road Area Reconstruction 080224\_Proposal Files 0PP.P03840\Northwoods Area Improvements Proposal_R2.docx
Preliminary investigations into Prior Lake Spring Lake Watershed District (PLSLWD) rules as they apply
to the proposed project indicate that stormwater management rules and associated permitting will be
triggered. Our water resources team will conduct a thorough site assessment to gather existing conditions
data and identify hydrologic and infrastructure characteristics of the project area. We will work with city
staff to review records for the existing drainage infrastructure, including existing adjacent stormwater
management ponds. Early in the process, our team will review MS4, PLSLWD, City, MnDNR, and FEMA
requirements as they relate to the project to ensure all regulations are clearly understood and incorporated
into the design. From there, we will perform preliminary hydraulic and hydrologic analyses to determine
pre- and post-construction runoff conditions, including inlet spread, pipe layout and capacity, and detention
or storage changes. We will use the results from our models to design a comprehensive storm sewer system
that meets the hydraulic capacity requirements and integrates with existing infrastructure. For the
installation/upsizing of the culvert under Fremont Ave, as determined in the Resilience Study, it is our
assumption that the pre- & post-construction flood modeling has been completed by others as part of that
study, that digital model files are available for use, and no additional model development will be required.
For the Northwood Road Wetland Outlet, we are assuming the same information is readily available for
incorporation.
Our water resources team will identify and assess opportunities to meet the stormwater management
requirements from the regulatory agencies. However, due to the linear nature of the project area which is
fully developed, there are very limited to no opportunities for additional stormwater management BMP’s
to be installed within existing right-of-way. Instead, we will investigate opportunities to reduce directly
connected impervious areas, utilize drainage swales and other linear treatment opportunities. If the
stormwater management requirements cannot be completely met within the project boundaries, it is our
assumption that the remaining requirements will be managed and met through a combination Off -Site
Stormwater Management, PLSLWD Volume Control Credits, and PLSLWD Public Linear Project Cost
Cap.
It is assumed that city staff will provide street OCI ratings, pavement management data, applicable record
drawings, and utility televising reports/proposed utility improvements. It is also assumed that geotechnical
services will be provided by WSB for the project under a separate contract directly with the City of Prior
Lake. Geotechnical services will include preliminary materials investigations by completing soil borings
throughout the proposed project corridors to provide recommendations on the proposed street
improvements and utility construction. A geotechnical report will be developed with a summary of findings,
including the recommended street improvements (identifying those feasible for mill and overlay and those
requiring reconstruction, taking into account utility improvement needs) with proposed street section,
bituminous mix designs, and other relevant construction recommendations.
Task 4 – Public Engagement & Project Communications
From feasibility through construction, clear and consistent public communication will be key to a successful
project. Our team will work with city staff to develop a public involvement approach that informs, engages,
and provides an opportunity to collaborate with project stakeholders. The public engagement plan will allow
interested parties an opportunity to participate in the project, while giving city officials the confidence that
all issues are addressed throughout the project development process. Our communication team, led by
Nicole Krause, will approach engagement in three phases: feasibility, design, and construction.
Feasibility Engagement
In the feasibility stage, our goal will be to connect with homeowners to understand their needs and share
project information. This phase will be critical to not only create a community-informed plan, but also
prepare the public and stakeholders for design and construction. We anticipate using the following tools:

Page: 7
N:\Proposals\Prior Lake\2026-2027 Northwood Road Area Reconstruction 080224\_Proposal Files 0PP.P03840\Northwoods Area Improvements Proposal_R2.docx
• Communications plan. We will develop a project communications plan to define and confirm
stakeholders, communication activities, schedule, and roles.
• Project website. At the onset of the project, our team will develop and host a project website and
manage all website content. This will streamline project content sharing to the community
through a single source and share key information such as designs, schedule, contacts, and more.
The webpage will also feature a project subscription form so people can sign up for updates with
their email or phone number for text messages.
• Construction survey (1). Our team will create and mail one survey. This survey will gather key
information that will help us better understand existing conditions and each property owner’s
needs during construction. This includes information on deliveries, waste management, parking,
and more. Bolton & Menk has successfully used this tool on other projects and has found it
critical in getting ahead of potential conflicts. This survey will be mailed along with a letter
notifying residents of the start of topographic survey work and what to expect during that process.
The letter will also let them know about the project website and how to communicate with the
project team. This letter will be mailed approximately one week prior to topographic survey
commencing.
• Neighborhood meetings (2). We will organize, promote, prepare meeting materials, and attend
two neighborhood meetings throughout the feasibility stage of the project. The intent of these
meetings will be to identify key issues and concerns from residents. These meetings will be
promoted via email and mail.

Project Schedule
We are committed to following a project schedule that meets the City’s expectations. The project will be
completed in two phases over the 2026 and 2027 construction seasons. The feasibility study will be
completed for the entire project area and will determine the limits of each phase of construction. Each
project phase will then be designed and bid out for construction independently. Our proposed schedule will

Public Works Director / City Engineer
City of Prior Lake
4646 Dakota Street SE
Prior Lake, MN 55372-1714
Re: Proposal for: Geotechnical Evaluation and Coring
Northwood Road Area
Prior Lake, Minnesota
Dear Mr: Brotzler;
Thank you for the opportunity to provide professional services for a geotechnical evaluation for
the above referenced project. This lump sum fee proposal is in response to the email from Brad
Fisher with Bolton & Menk, Inc. on July 18, 2024. In this proposal, we present a description of
our understanding of the project, an outline of the scope of work we are to provide, and a fee
schedule and estimate of charges for our services.
It is our understanding that this project consists of reconstruction of Northwoods Road NW
between Spring Lake Road and 154th Street NW, including several Island View Road and Island
View Circle and several cul-de-sacs. This project also includes mill and overlay of Fremont
Avenue, Hawk Ridge Road, Knollridge Drive, and several cul-de-sacs.
We understand the horizontal and vertical parameters of the project will not be changed from
existing conditions.
A. Project Objectives
Based upon our experience with similar projects the objectives of our geotechnical and coring
services are to perform subsurface borings, core the bituminous areas, classify and analyze the
soil samples and bituminous cores, discuss groundwater issues, and prepare recommendations
for reconstructed pavement design and mill and overlay.
B. Scope of Basic Services
Based on our understanding of the project we proposed the following scope of services:
1. Site Access
Based on a review of the information provided by Bolton & Menk Inc, it appears that the
site can be accessed with our CME-55 truck mounted auger drill and pickup truck based
coring rig.
EXHBIT 1
Northwood Road Area
July 24, 2024
Page 2
Based on posted speed limits or the roadway in a residential area, we anticipate that
traffic control can be accomplished with flashing lights and traffic cones to allow
vehicles to self regulate around the drilling and coring operations.
2. Bore Hole Locating and Gopher State One Call
WSB will stake the proposed bore hole locations with GPS (Global Positioning System)
technology. Core locations are best determined in the field by our experienced crew to
identify areas of concern or interest.
Prior to sending a drill rig to the site WSB will contact Gopher State One Call (GSOC) and
have them request public underground utility owners mark and clear our proposed bore
hole locations of their utilities. If there are private underground utilities that are not
located by GSOC, you must notify WSB immediately. WSB will take reasonable
precautions to avoid underground facilities.
3. Subsurface Test Borings
We propose to complete 27 standard penetration test borings to depths of 14.5 feet
below grade. In the standard penetration test borings we will sample and record blow
counts at 2½ foot intervals to 15 foot depths and then at 5 foot intervals to the
boreholes termination depth.
If unsuitable soils (existing fill, organic soils, etc…) are encountered at the proposed
boring termination depth(s), it will be necessary to extend the borings into more
competent materials. This will allow us to better evaluate potential construction issues.
Coring samples will be 6 inches in diameter and a hand auger completed through the
aggregate base material.
In Minnesota, a boring that is deeper than 15 feet and sealed within 72 hours is
considered a temporary boring / environmental well and requires Well Sealing Records
be submitted to the Minnesota Department of Health. If the temporary boring /
environmental well is extended to depths of more than 25 feet, a Construction
Notification form and Fee are required. WSB will fill out the MDH notification and
sealing record forms and sign on behalf of the owner unless directed otherwise.
4. Schedule, Bore Hole Samples and Laboratory Testing
Based on our current drilling backlog, we anticipate that we can mobilize our truck
mounted auger drill to the site in about 6 weeks from the time that written
authorization is provided. Laboratory work and report preparation will take about 2 – 3
weeks following completion of the field work. It should be noted that this schedule may
change based on timing of authorization, site conditions and other factors. Should our
anticipated schedule change we will let you know. This estimate is based on work being
Northwood Road Area
July 24, 2024
Page 3
completed during normal business hours, 7am to 6pm, Monday through Friday.
Additional charges will apply to night or weekend drilling.
Samples retrieved during drilling will be returned to our laboratory where they will be
reviewed, classified using the Unified Soil Classification System (USCS) and logged under
the direction of a geotechnical engineer. Select samples will be set aside for laboratory
testing. We may perform routine laboratory tests on selected soil samples obtained
from the exploration. This may include determinations of natural moisture content and
unconfined compressive strength with a calibrated penetrometer if cohesive soils are
encountered and gradations on select sand samples from the borings.
Such tests will aid in determining soil classification and properties and potential
behavior characteristics to help guide our recommendations.
5. Geotechnical Engineering Report
Information gathered for this project will be used to prepare a geotechnical report. The
report will summarize our findings and provide a discussion of subsurface soil and
groundwater conditions encountered in our borings and how they may affect the
proposed construction of pavements and installation of utilities. The report will discuss
the core thicknesses and quality and identify any concerns such as raveling, etc. The
report will also provide estimates of ground water depths/elevations and settlement
under the assumed structural loads, site grading, and a discussion of soils for use as
structural fill and site fill.
We will provide you and any identified members of your design/project team with a PDF
copy of our geotechnical report. If requested, we will also provide you with an original
hard copy.
This geotechnical proposal is presented for engineering services to determine the
structural properties of the soil at the specified site. It does not cover an environmental
assessment of the site, or environmental testing of the soil or groundwater.

If additional borings or deeper borings are needed, or if engineering and testing are
requested beyond that necessary for preparation of our report (post-report
consultation, report revision due to changes in building design or location, specification
review, or pre-construction meetings), the increase in our fees will be in accordance
with the rates previously indicated or at the unit prices shown on the enclosed Rate
Schedule for hourly services.
If you have any questions regarding our scope of services or how they may be modified
to meet your project needs please feel free to give us a call to discuss.
C. Closure
This letter represents our complete understanding of the proposed scope of services. If you are
in agreement with the scope of services, attached General Contract Provisions, and proposed
fee, please sign in the appropriate space below and return one copy to my attention. If you have
any questions about this proposal, please feel free to call us at 952-737-4660.
This fee proposal is valid for ninety (90) days from the creation date noted in the header. WSB
may reissue a revised proposal upon request if the indicated time period has lapsed. Should the
scope of work change in nature or be expanded to include additional services, we reserve the
right to renegotiate the fees and contract provisions with you. However, once we begin work on
this project, any counteroffers will not be accepted.
WSB appreciates the opportunity of being considered for this project and we look forward to
providing our professional services to you.
Sincerely,
WSB
