SUBJ: Approve Environmental Assessment and Consultant Design Services with
I Barton - Aschman for Trunk Highway 5 North Access Boulevard
Project No. 90 -17A
I The proposed Arboretum Boulevard project, when completed, will provide a new two -lane
urban roadway that will function as an access boulevard to properties along the north
I corridor of Trunk Highway 5 between CSAH 17 (Powers Boulevard) and Trunk Highway
41. A critical aspect of this proposed project is to administrate the planning and design
processes in accordance with federal and state standards in order to secure federal funding
1 from the Service Transportation Program (STP) which is an integral part of the Intermodal
Surface Transportation Efficiency Act of 1991 (ISTEA).
1 The first step of this process is to prepare an Environmental Assessment (EA) document
based on a build alternative plus a no -build alternative within the project corridor. This EA
will be prepared in conformance with the MnDOT HPDP guidelines, which meets the
I Federal Highway Authority (FHWA) requirements. It is intended that MnDOT would
sponsor the project and EA document and request that the FHWA adopt the document and
declare a Finding of No Significant Impact (FONSI). If the City were to sponsor the project
and conduct and EAW and Negative Declaration under the State of Minnesota
Environmental Review Program process, the EA /FONSI process would still need to be done
I separately in order to obtain federal funds. Therefore, MnDOT's sponsorship eliminates
the additional document and environmental review process and will save the City time and
money.
1 The attached agreement provides a detailed description of the services to be provided with
the preparation of the EA document, obtaining the Finding of No Significant Impact
I (FONSI) and preparation of final design and construction documents. It is important to
note that Barton - Aschman has been working with the City and the City's Trunk Highway
1
II t41 PRINTED ON RECYCLED PAPER
1
I 5 Corridor Task Force to determine a preferred alignment alternative for the EA. This
recommendation is expected to presented to the Council in the very near future.
I The proposed cost for providing these services has been established at a not -to- exceed
amount of $240,000, based on preliminary engineering and environmental study at $120,000
and final design and construction documents at $120,000. It should be noted that the
I preliminary engineering and environmental assessment preparation was previously presented
at $135,000. However, $15,000 previously authorized by the Council to begin the ground
work and acquire state commitment has been spent and deducted from the maximum fee
1 now presented.
The timeframe for this project has been condensed into 24 months in order to be completed
1 simultaneously with the final design for Trunk Highway 5 between County Road 17 and
Trunk Highway 41. It is therefore recommended that the City Council authorized the
consultant services agreement with Barton - Aschman Associates, Inc. for preparation of the
1 environmental study and final design of the Arboretum Boulevard Project No. 90 -17A.

ATTACHMENT A
CITY OF CHANHASSEN
Arboretum Boulevard (Trunk Highway 5 - North Frontage Road)
Scope of Services
GENERAL
The proposed Arboretum Boulevard project, when completed, will function as a frontage '
, road along TH 5 providing access to properties adjacent the corridor. The project's west
terminus intersects TH 41 and generally parallels TH 5 on the north for approximately
2.5 miles before terminating at CSAH 17 (Powers Boulevard).
The proposed TH 5 frontage road construction will provide a new two -lane urban
roadway on new alignment that meets current geometric standards for federal and state
aid funded projects. A key goal of the project is to satisfy the requirements associated
with securing federal funding from the Surface Transportation Program (STP) which is
an integral part of the Intermodel Surface Transportation Efficiency Act of 1991
(ISTEA).
Alternative geometric layouts will be prepared and evaluated utilizing traffic forecasts,
land -use planning studies, and other pertinent design criteria. An Environmental
Assessment (EA) will be prepared concurrent with the concept phase of the project to
determine environmental impacts associated with the action.
Final design activities will commence upon approval of the final geometric layout and
Environmental Assessment.
1.0 PRELIMINARY ENGINEERING AND ENVIRONMENTAL STUDY ,
1.1 Data Collection /Inventory
all data necessary for the completion
The consultant will procure ry letion of the tasks outlined in p
this scope of work. This shall include but may not be limited to:
1.1.1 Half- section maps, aerial photography, and plats
1.1.2 Local comprehensive plans
1.1.3 Available roadway as- builts and right -of -way maps
1.1.4 Previous pertinent studies and reports
1.1.5 Soils information
1.1.6 Traffic counts and forecasts
1.1.7 Wetland and floodplain maps
1.1.8 USGS quadrangle maps
1.1.9 Utility locations
1 i
1
1

1.2 Preliminary Layouts
The consultant will utilize city supplied aerial mapping of the project area to develop a
maximum of two (2) design build alternatives. These alternatives will integrate
comprehensive land use planning objectives with roadway alignment and intersection
design. These alternatives will be prepared at an appropriate scale (i.e., 1" = 100') and
will be used as a visual tool during the public involvement process.
A roadway profile using two -foot interval contours from aerial photography will be
'prepared as early in the process as possible in order to develop preliminary construction
limits. These construction limits will be a very important component in determining
environmental impacts.
These layouts will be developed in close coordination with the city and MnDOT.
1.3 Agency Correspondence and Coordination
1.3.1 Contact Agencies as Appropriate and Review Environmental Issues
1.3.1.1 Minnesota Department of Natural Resources
1.3.1.2 US Army Corps of Engineers
1.3.1.3 US Fish and Wildlife Service
1.3.1.4 Minnesota Pollution Control Agency
1.3.1.5 Riley - Puratory Creek Watershed District
1.3.1.6 Minnesota State Historic Preservation Office
1.4 Environmental Assessment A
1. (E )
' The Arboretum Boulevard project is anticipated to be a Class III action according to
FHWA regulations, 23 CFR Part 771. Consideration of FHWA's requirements is driven
by the decision to seek federal funding for the project. Both MnDOT and FHWA must
ultimately sign the EA, thereby indicating their adoption of the document and its
findings. A Finding of No Significant Impact (FONSI) would then be requested by
' MnDOT and, assuming no major impacts, signed by FHWA.
Barton - Aschman's proposal is to have MnDOT sponsor the project through the FONSI
stage rather than have the city sponsor the project through an EAW and Negative
Declaration under State of Minnesota Environmental Review Program process, and then
have the EA /FONSI process done separately in order to obtain the federal funds. The
major advantage of our approach is that only one document and one environmental
review process is needed, because MnDOT has received the state's approval to have an
alternative review program that combines the state and federal regulations. The EA
document will include a listing of federal, state, and local permits and approvals required
for the proposed project. The net result, assuming federal funding, is that the City of
111
•

Chanhassen will save time and money with the MnDOT sponsorship Ch Y P P of a single I
document.
1.4.1 Air Quality I
The air quality analysis will be based on the results of the traffic. It will make use of 1
turning movement volumes to estimate air pollutant emissions and concentrations. The
procedures set forth in the EPA's "Volume 9" guidelines and emission rate correction
factors from MOBILE 4.1 will be used to estimate Carbon Monoxide (CO) emissions.
The CALINE dispersion model will be used to estimate CO concentrations at receptor
sites. Up to two (2) receptor sites will be modeled for up to two build alternatives and
one no -build alternative. The final concentrations will be compared with state and
federal standards to determine compliance. The consultant will attend a meeting with
the Minnesota Pollution Control Agency and /or MnDOT staff in the course of this
analysis.
Clean Air Act regulations are currently being developed by EPA. An areawide burden
analysis may be necessary for this project if the project meets regional threshold criteria
yet to be established. This scope of work does not include such an analysis.
1.4.2 Bicycle and Pedestrian Movement 1
Bicycle and pedestrian trail planning within or near the project corridor will be
investigated on both a local and state governmental level. Any disruption or conflict
with these activities will be identified and mitigation measures discussed.
1.4.3 Construction Impacts I
Construction impacts will focus on maintenance of traffic under construction, temporary
I
dewatering and dust and noise controls. Up to two build alternatives will be analyzed
and these may have similarities in terms of their impacts. Earthwork management will
be evaluated specifically in the area of excess material disposal. It is assumed that the
1
no -build alternative will have no construction impacts.
Note: Emphasis will be placed on mitigating the effects of construction, particularly
1
temporary disruption of access to businesses and residences and possible traffic detours.

1.4.4 Socioeconomic and Neighborhood Impacts
This task includes the following subtasks:
• Demographic research of study area (residential, employment, population)
• Social impacts to neighborhoods (community cohesion)
• Impacts to sensitive groups (elderly, handicapped, children, minorities)
• Pedestrian/bicyclist impacts
• Right -of -way impacts (relocations, access changes)
Census data for 1990 that is readily and currently available will be used to determine the
demographics of the area. Local planning agencies are expected to provide information
on socioeconomic trends, community cohesion, etc. Right -of -way impacts will include a
conceptual stage relocation analysis and analysis of access changes to businesses, homes,
farmsteads, and industry.
1.4.5 Erosion
Temporary and permanent erosion control measures are required because of the
topography of the area and the interspersion of streams and wetlands. US Soil
Conservation Service maps for Chanhassen will be reviewed to identify the presence of
erodible soils. Impact are where damage from erosion is probable will be identified in
the EA. Erosion control measures, in particular MnDOT standard specifications for
' construction (18035 and 2573) will be identified. If special provisions are warranted and
practicable, these will be discussed as mitigation measures.
' 1.4.6 Farmlands
Farmland Protection Policy Act (FPPA) procedures will be followed for this project. If
' necessary, Form AD -1006 will be submitted to the Soil Conservation Service for site
assessment.
1.4.7 Floodplains
The consultant will identify designated floodplains within the study corridor. Floodplain
r encroachments due to the proposed project will be estimated. Recommendations will be
made regarding necessary measures to mitigate unavoidable impacts of the project.

1.4.8 Groundwater, Geology, and Earthborne Vibrations
The consultant will gather available data on the bedrock hydrology, surficial geology,
groundwater table, and wills within the study corridor. Data will be gathered through
contacts with public agencies, literature search, review of maps, and site visits. Potential
impacts from the proposed project and necessary mitigation measures will be identified.
1.4.9 Identify Potential Contamination Sites 1
Potential sources of existing soil, and water (surface and groundwater) contamination in
the project corridor will be identified. A review of historical records /references and a
site reconnaissance will be made. Specific tasks to be conducted include:
A. Contact with all appropriate federal, state, and local regulatory agencies to review
1
records of past hazardous materials incidents (eg., spills, improper storage,
discharges, leaky underground storage tanks, etc.) that may have occurred on the
site or in nearby areas that could affect the site. At a minimum, this will involve 1
a review of the following data sources:
• National Priorities List 1
• Comprehensive Environmental Response, Compensation, and Liability
Information System
1
• MPCA Permanent List of Priorities
• MPCA Regulatory compliance, Hazardous Waste Enforcement Log
I
• MPCA List of Permitted Solid Waste Facilities
• MPCA Hazardous Waste Permit Unit Project Identification List
• MPCA 1990 Metropolitan Area Waste Disposal Site Inventory
• MPCA Statewide Open Dump Inventory
1 I
B. A literature review pertaining to the environmental setting, including g s ite geology,
gy,
groundwater, surface waters, potable water supply, and sensitive environmental
areas. These issues will be addressed in other sections of the Environmental
Assessment and incorporated, as needed, in the contamination assessment.
C. A physical site inspection of the proposed corridors to evaluate the potential for I
past or present hazardous materials usage.
Based on this information, if it is determine that additional investigation is required 1
(environmental audit), that work will be handled through a supplementary contract.
1

Cultural Resources
C s
r A subconsultant will conduct a visual inventory of the project corridor to identify areas
of historical or archaeological potential. In addition, the subconsultant will conduct a
Phase I review of the corridor which includes a literature and records search; interviews
with local informants; preparation of report (map showing known sites and areas with
cultural resource potential, supplemented with written descriptions and comments).
I Based on this information, if it is determined that additional investigation is required
(Phase II and III), that work will be handled through a supplementary contract.
I 1.4.11 Land Use, Zoning, and Community Facilities
Land use and zoning in the project area will be identified and inventoried from a site
I reconnaissance, aerial photographs, and local planning sources. Impacts to land use and
zoning patterns resulting from the project will be analyzed. Public and private
community facilities (schools, churches, public buildings, etc.) in the vicinity of the
I project area will be inventoried and any projected impacts to such facilities will be
analyzed. Emergency services in the project area will be identified and changes in
services to the study area will be analyzed. One person -day of site reconnaissance/
1 meetings is included in the scope of work.
1.4.12 Noise Analysis
I The noise analysis will identify and quantify the noise impacts associated with the
construction and operation of the proposed project.
I The existing land uses along the proposed roadway alignment will be examined and field
monitoring of noise levels conducted to quantify the existing noise environment. The
I monitoring will be done by the consultant with an approved noise level analyzer at up to
six sites which may be considered representative of the land use conditions over a larger
I area.
Future noise levels along the proposed roadway will be predicted for each alternative by
I utilizing the STAMINA 2.0 traffic noise computer model. The predicted noise levels will
then be compared with the existing noise levels and with the appropriate federal, state,
and local noise standards to determine where noise mitigation measures are justified.
I The effectiveness of the various potential mitigation measures will also be evaluated.
Construction noise impacts will be estimated and potential mitigation measures
identified. The results of the noise analysis will be presented in the EA.
1 1.4.13 Parks and Recreational Lands
I Park and recreation evaluations for the proposed build alternative will be included with
the land use inventory in order to determine any known affected public recreation land,
1 6
1
1
1
wildlife management areas, school properties, or archaeological or historic properties.
The focus of this subtask will be to demonstrate to all agencies that, through careful
design, the encroachment on these lands is being avoided or held to the minimum
required. Section 4(f) /6(f) evaluations will be necessary, they will be conducted and
processed with the EA document. 1
1.4.14 Right -of -Way and Relocation
The purpose of this special study is to identify the right -of -way impacts associated with 1
the proposed alternatives. This task requires identification of affected parcels including
property ownership, market value, year of construction and tax assessments, and existing
and planned land use. All partial and total acquisitions will be identified as well as a
survey of potential replacement sites for any displacements created by each alternative.
The findings of this analysis will be presented as a summary in the Environmental
Assessment.
1.4.15 Stream Modification
The proposed study corridor is in rolling hills west of Chanhassen in a developing area. 1
There are several small drainage crossings of the existing highway. The proposed project
would likely involve construction of new drainage crossings (probably culverts), potential
storm sewer construction in areas of cut with steep backslopes, and storm water quality
facilities. Stream modifications may result from these activities. These modifications
will be described and any results impacts will be discussed.
1.4.16 Traffic
This section of the Environmental Assessment will discuss the impacts of traffic 1
operations and mitigation measures. Traffic operations issues could include delays,
detours, signal operations, and turning movement conflicts. Traffic volume and speed
information will be used as a basis for this analysis, along with the geometric design of
the alternatives. An evaluation will be made of the impacts of these operations on the
immediate environment and on regional and through travel.
1
1.4.17 Vegetation, Fish, and Wildlife
Natural vegetation can be expected within the project study area in association with 1
streams and wetlands. Major sites will be identified through field reconnaissance, and
characterized as to quality.
1
DNR area biologists will be consulted for location of natural vegetation that is
particularly unique to the area. Particular attention will be given to parcels of
undisturbed native vegetation that should be preserved for urban wildlife corridors.
7 1
1
Impacts to natural vegetation by each alternative will be identified and compared to
determine the least impact alternative.
Habitat for fish and wildlife can be expected in the project study area. Expected and
known fish and wildlife will be identified through contact with public resource agencies
and the published literature.
DNR wildlife and fisheries biologists will be consulted regarding locally occurring
species. Special attention will be given to identifying movement patterns in relation to
the existing roadway. Impacts to habitat types and fish and wildlife species will be
' identified. Measures to minimize impacts will be described.
1.4.18 Visual Quality Impacts
The visual quality impact analysis will follow MnDOTs six-step Visual Impact
Assessment Process. Visual resources and viewers will be identified, existing visual
quality will be defined, impacts will be analyzed and summarized for each build
alternative and mitigation methods will be identified. Photographs will be taken of the
project area, and a maximum of three (3) will be used to illustrate sensitive visual
resources in the Environmental Assessment Document. Determination of significant
visual impact will be based upon the proximity to and number of people viewing the
affected area.
1.4.19 Threatened and Endangered (T & E) Species
Threatened and endangered (T & E) species are not expected to occur within
Chanhassen. However, DNR will be consulted should the field reconnaissance identify
unexpectedly high quality areas.
DNR Natural Heritage Program database will be searched and DNR nongame biologists
will be consulted for documented occurrences of state and federal T & E species and
1 rare communities. If any such species or communities are identified, a supplemental
agreement will be negotiated to conduct a biological assessment and to determine
practical and feasible mitigating measures.
1.4.20 Water uali
Q ty
1 The consultant will contact public agencies to obtain existing water quality data for the
receiving water bodies impacted by the project and to review the criteria and
requirements for water quality.
Runoff quality and impacts to receiving water bodies will be assessed. Mitigation related
' to TH 5 improvements will be coordinated with watershed plans as well as the
comprehensive drainage plan of Chanhassen.
i
1
•
1
1
1.4.21 Wetlands
The consultant will review existing public agency wetland maps, aerial photography, and I
topographic maps to identify wetland areas. A field survey will be made to verify the
wetland types and limits. Public agencies will be contacted to verify the wetland types,
limits, and specific concerns within the study corridor.
Potential impacts of the proposed highway project alternatives will be quantified. If
permits at the local, state, or federal level are needed for the project, they will be listed
in the EA. However application for and processing of permits is beyond the scope of the
EA. 1
1.4.22 EA Documentation and Review
The Environmental Assessment (EA) document will consider a build alternative plus the 1
no -build alternative within the project corridor. The EA will be prepared in
conformance with the MnDOT HPDP guidelines, which meets the FHWA requirements.
The EA will describe the social, economic, and environmental impacts of the proposed
project and offer mitigating measures to eliminate or lessen those impacts.
The EA will summarize the impact studies as listed in 1.5.1 through 1.5.21 of this section. 1
A draft EA (20 copies total) will be submitted to the City of Chanhassen and MnDOT
I
Metro District and Central Offices for internal review. The review will take 14 calendar
days from receipt of the report on the date established with the consultant. Following
review of the draft, comments will be discussed at a progress meeting. The consultant 1
will then incorporate the changes into a final report submitted for signatures (12 copies).
Time for revision of the draft EA will be included in the project schedule. However, it
is assumed that changes (if any) to the final report submitted for signatures will be of a
minor, editorial nature and, therefore, no revision time will be included in the schedule.
Upon receipt of the signed cover page (after 14 calendar days), the consultant will 111 provide 50 copies to MnDOT for distribution by an agreed date. Twelve (12) additional
copies of the final approved document will be submitted upon request.
1.4.23 Meetings 1
News releases and legal notices of the location public hearing will be prepared by the I
consultant and distributed in advance of the meeting.
The purpose of this hearing, conducted by the consultant, is to provide information on
the location and preliminary design of the alternatives studied in the EA and to receive
public input on the project. The consultant will review the potential impacts of each
alternative and prepare the informational materials and graphics needed for the
I
presentation.
1
1
If prudent, the location public hearing could be combined with the design public hearing,
thereby providing as much information available as possible for public and reviewing
agencies consideration.
Public input received at this hearing will be considered in the selection of the preferred
alternative. MnDOT will make arrangements for the meeting facility. All oral
comments recorded on the transcript and all written comments received at the hearing
and during the comment period will be included in the documentation of the hearing
proceedings which will be compiled by the consultant. 'This information will be
summarized in the Negative Declaration /FONSI submission package for FHWA.
1.4.24 Negative Declaration
A Negative Declaration is the state equivalent of a FONSI at the federal level. The
Responsible Governmental Unit (RGU), in this case MnDOT, makes the Negative
Declaration and distributes a notice of its decision not to prepare an EIS to all agencies
and persons on the EA distribution list, to those persons who offered comments on the
EA, and upon request.
' The consultant will coordinate with the city, MnDOT Office of Environmental Services
and Golden Valley -Metro West District. The consultant will draft a letter stating the
MnDOT decision and attach any supporting findings of fact and conclusions. The
Findings of Fact will briefly summarize comments received on the EA and MnDOTs
responses in addition to procedural findings.
' 1.4.25 Finding of No Significant Impact (FONSI)
MnDOT requests that FHWA issue a FONSI on the basis of information contained in
the EA and any comments received on the report or through public or agency
involvement. The request also indicates the reasons for selection of the preferred
alternative.
The consultant will prepare the request package as follows:
A. Assemble EA, hearing transcript, and comment file.
B. Prepare a statement of the preferred alternative and why it has been selected.
C. Respo nd t o substantive comments in a brief narrative. It is assumed that the
any
EA will already be reviewed and approved by FHWA prior to the public hearing.
However, new comments received during and after the hearing will be addressed
for the FONSI request. New technical analysis is not assumed to be needed.

1 Re: Arboretum Boulevard Consultant Agreement
Dear Mr. Ashworth:
Attached are three copies of the agreement to provide environmental assistance and
design of the Arboretum Boulevard parallel to TH 5 between CR 17 and TH 41. This
contract is based on the numerous meetings we have had since May of 1992 and I
believe reflects all of our understandings.
The time frame for this project has been reduced to 24 months in order to coincide with
the ending of the final TH 5 design between CR 17 and TH 41.
The costs for these consultant services are based on the enclosed Table 1, revised
October 27, 1992, that was incorporated with your letter to Mr. Bill Crawford.
1 Preparation cost of the Environmental Assessment and 4(f) and 6(f) statement(s)
maximum cost would be $135,000. Due to the fact that we have spent approximately
$15,000 as previously authorized by the council, we have deducted $15,000 from this
maximum fee so that the Environmental Assessment (FONSI) and 4(f) and 6(f)
statement cost will be $120,000. The final design cost is based on six percent of the
estimated construction cost of the facility which is $2 million. This amounts to $120,000.
It is our understanding that MnDOT has basemapping available for the majority, if not
all of the project limits. Should additional basemapping be required it is our
understanding that the city will provide us with this information.

I SUBJ: North Frontage Road Construction in Conjunction with Highway 5
Reconstruction Project
I Staff has attempted to keep both the HRA and City Council informed as to negotiations in
regards to having the Highway Department carry out the north frontage road construction from
State Highway 41 to County Road 17. The previous approval recognized that the state would
I have difficulty carrying out the construction of the frontage road through the Lake Ann property
(property was acquired by the federal government as a part of the original grant application for
Lake Ann and displacing park property so obtained appeared to be so restrictive so as to slow
I down the mainline construction). Since that date, Barton Aschman has completed the 30%
engineering analysis whereby it was shown that a major portion of the mini- storage property
would have to be taken as well as Prince's parking lot. The state considered these to be major
I potential cost implications and, accordingly, revisited the Lake Ann issue. By the state acquiring
the existing house at Lake Ann and rededicating that land to the city, no net acreage would be
taken from the park property. Accordingly, they are in agreement that they would carry out the
frontage road construction from Highway 41 to County Road 17. This decision was significant
for the city in that our costs were reduced from approximately $2 million to $1.5 million
(estimate if we had to build the frontage road from 17 to Audubon) to $500,000 (current
1 estimate).
I The HRA was supportive of the revised project and a letter, similar to that attached, was
authorized to be sent to MNDOT. In presenting this item to the City Council, questions came
out as to the costs of right -of -way which staff was not prepared to respond to. Since that date,
II we have met with MNDOT and Barton Aschman and have confirmed that right -of -way
acquisition is not a permissible cost item within the ISTEA Funding categories. Current cost
estimates for the right -of -way would be approximately $700,000 to $900,000 with the state being
I responsible for approximately 20% of those costs. In essence, this would bring the total cost to
the city at approximately $1.2 million. Although I have stressed with the HRA /City Council that
a major portion of the project could not be assessed because of a lack of benefit to adjoining
es
to PRINTED ON RECYCLED PAPER

properties, I sincerely believe that at least 33% of the project could be assessed. Accordingly,
Y
I believe that we would be in a position to assess the project costs at a level equal to our
participation in the project, i.e. $1.2 million. It should also be remembered that any deficit costs
for this project were proposed to be shared on a 1/3 each basis to each of the tax increment
districts (including one district which is yet to be created) lying between Hwy. 41 and CR 17.
Approval to submit a letter similar to that as attached is recommended. (Note: Our meeting with
MNDOT included agreement by MNDOT that, if a park and ride lot is included within the
project, that such would be an eligible cost under ISTEA.)
Paralleling and supporting the frontage road project is the Highway 5 Corridor Study contract.
Payment of costs to develop a specific plan for this corridor including official mapping, overlay
districts, and ordinances is critical if we are to assure that the plan presented by Bill Morrish
becomes a reality. Similar to the frontage road construction costs, costs associated with
developing the corridor study are proposed to be shared equally between the three districts,
existing or proposed to exist between Hwy. 41 and CR 17. This office supports the
recommendations being made by our Planning Director, Paul Krauss (see attached
report/recommendations). Approval of that report is also recommended.

Re: Trunk Highway 5 (TH 5) Reconstruction Project, S.P. 1002 -61
Dear Mr. Crawford:
During the pas: several months numerous meetings have been held between MnDOT
staff, Barton - Aschman staff, and City of Chanhassen staff concerning the referenced
project. Many subjects were discussed and verbal agreement was reached between the
various participants. The purpose of this correspondence is to initiate a letter of
understanding between MnDOT and the City of Chanhassen so that all parties are aware
of agreements reached. Items discussed to date include the following:
1
1. Revisions to TH 5 in the vicinity of Lake Ann Park. To avoid excessive right -of-
way cost on the south side of TH 5 between CSAH 17 and Audubon Road,
widening of TH 5 mainline will be switched to the north side. MnDOT will pay
the city for Lake Ann Park land required to accommodate this mainline
relocation. This taking would be in addition to the Notermann farm property. It
is our understanding that the net acreage that MnDOT will pay for is 1.75 acres.
r
1
1
2. Incorporation of a continuous north frontage road into the TH 5 design project 1
which is programmed for fiscal year 1996 construction (CSAH 17 to TH 41). It is
the city's understanding that the frontage road will be a two-lane facility with turn
lanes as necessary at major intersections. The City of Chanhassen has agreed to
prepare and pay for the necessary preliminary engineering, environmental
assessment, and 4(f) and 6(f) statements (due to Lake Ann Park) at a total cost of
approximately S135,000. The city will also pay for the final design cost for the
1
north frontage road ($120,000). MnDOT will provide the necessary design
mapping, project overview, and sponsorship of the environmental and design
documents. They will also support the project for federal participation in the 1
construction cost of the north frontage road. This will provide 80 percent of the
construction cost of the north frontage road. Of the remaining 20 percent of
construction cost, MnDOT will contribute one -fifth based on the original
proposed frontage road length (approximately 2,300 feet) versus the new frontage 1
road length (approximately 11,600 feet). MnDOT will act as agent in the
acquisition of all frontage road right -of -way. The city will reimburse MnDOT for
all frontage road right -of -way cost over and above that cost which would have 1
been incurred by MnDOT if the original plan (approximately 2,300 feet) had been
built. Geotechnical surveys were not discussed at our meetings, therefore we are
herein requesting that MnDOT incorporate the frontage road geotechnical
g rP g g
:inventory with the mainline geotechnical work at no cost to the city. 1
t
1
1
1
I 3. In:c;orporation of a pedestrian underpass within the TH 5 design project adjacent
to Bluff Creek. This pedestrian underpass will be an arch -type of culvert and the
city will provide 50 percent of the local share cost for this improvement.
1
4. A new public school has been proposed within the southeast quadrant of the
intersection of CR 117 and TH 5. To rovide the greatest opportunity for
P g pp y use of
the site. MnDOT staff will review and attempt to hold right -of -way takings
ad ja.ce:nt to the school site to a minimum.
Based on verbal discussions with your staff, we have directed Barton- Aschman to initiate
work on the necessary environmental documents, and to initiate preliminary design of
t:7e north frontage road. We would appreciate confirmation of our understanding
through a letter of understanding between MnDOT and the City f Chanhassen. t
ty a` sen. Shou.;l
you have any questions concerning this request we would be pleased to meet with you
and your staff.

Dear Mr. Ashworth:
You undoubtedly have been briefed, or will be briefed shortly, about the recent meeting ■
between MnDOTs Golden Valley staff, Chanhassen city staff, and Barton - Aschman staff.
This meeting was held to explore revisions to the TH 5 mainline as well as potential
TH 5 north frontage road improvements.
After reviewing the proposed alignment of TH 5 in the vicinity of the storage facility,
child care center, and Prince's studio, MnDOT has suggested that the mainline alignment
of TH 5 be relocated 62 feet to the north just east of CR 17, for a distance of
approximately one mile, to avoid expensive right -of -way taking. MnDOTs request came
after they were approached about MnDOT support for the north frontage road which
will encroach on park land.
to build the frontage road within the
MnDOTs feeling is that if the city is prepared g
park, an additional 62 feet to accommodate the mainline TH 5 design, would have a
marginal impact.
The 4(0 and 6(0 statements would have to be prepared for this alignment due to federal
guidelines. However, the positive impact for the city is that the entire frontage road
between CR 17 and TH 41 will now be eligible for federal funding. This would result in
a considerable savings for the City of Chanhassen.

In addition to the savings for the frontage road construction, MnDOT would reimburse
1 the City of Chanhassen the appraised value of the approximately 1.75 acres of right -of-
way required within park boundary to accommodate the realigned TH 5 mainline.
According to federal regulations, this money would have to be used to purchase
t additional park land within the City of Chanhassen because of the use of LAWCON
funds. Land purchased does not necessarily have to be adjacent to the existing park
although Paul Krauss, City Planner, suggested that that is part of the city's long -range
11
plan.
It was the consensus of those at the meeting that, if the frontage road continues to be
pursued, all efforts should be made to incorporate construction of the frontage road in
with the 1996 construction of mainline TH 5. As a result of this consensus, it is critical
that all environmental as well as the 4(f) and 6(0 work begin as soon as possible.
Based on this meeting with MnDOT we have revised Table 1 from our July 14, 1992,
letter to you indicating potential cost to the City of Chanhassen with MnDOT assistance
and without MnDOT assistance. When you have had time to review this new
information, along with the information provided in our July 14, 1992, letter, I feel it
would be beneficial to sit down and to discuss future actions necessary to implement this
critical improvement for the City of Chanhassen.
Sincerely yours,

I DATE: September 2, 1992
SUBJECT: TH 5 /Bluff Creek Crossing Alternatives
1
i A study of alternative crossings of TH 5 over Bluff Creek in Chanhassen has been
conducted. Three alternatives were developed which provide for both pedestrian and
hydraulic crossings of TH 5 at Bluff Creek. These alternatives are illustrated in the
I attached sketches and are described below:
Alternative 1, Bridge Crossing - Two standard roadway bridges would be utilized for TH 5
I as it crosses Bluff Creek. Based on the cost for the TH 5 bridge over the railroad tracks
in Chanhassen, the cost for the proposed bridges would be approximately $700,000.
I Alternative 2, Separate Pedestrian and Drainage Crossings - A 25 -foot wide precast
concrete arch structure would cross TH 5 at a right angle for pedestrian use and a
48 -inch reinforced concrete pipe culvert would be utilized for the Bluff Creek crossing.
I A 20 -foot wide opening in the arch structure is proposed in the roadway median.
Hancock Concrete reviewed this design and estimated the construction cost to be
$190,000 with a spread footing foundation and $225,000 with a piled foundation. Both
I costs include the 48 -inch concrete culvert crossing.
I Alternative 3, Common Pedestrian and Drainage Crossing - The pedestrian and drainage
crossings would be accommodated within a single 44 -foot wide precast concrete arch
structure which crosses TH 5 at the skewed angle of existing Bluff Creek. The estimated
1 cost for this alternative (from Hancock Concrete) would be $370,000 with a spread
footing foundation and $420,000 with a piled foundation. These costs also include the
short 48 -inch concrete arch culvert under the pedestrian trail.

The costs listed for each of the alternatives do not include items such as the pedestrian
trail, guardrail, etc. which would be approximately the same for each of the alternatives. 1
It should be noted that soil borings should be taken in the vicinity of the Bluff Creek
crossing when MnDOT conducts the geotechnical investigation for the project. This
information would allow for refinement of the estimated costs of the alternatives.

MEMORANDUM TO: Don Ashworth, City of Chanhassen
COPIES TO: Paul Krauss, City Planner
• PVC' ' ..! w 7992
FROM: Barry Warner CITY C..=
DATE: November 17, 1992
SUBJECT: TH 5 Access Boulevard Planning 1
As ou are aware, the TH 5 corridor Task Force will be meeting on a regular basis
y g Su
regarding issues pertaining to land use, urban design, and parcel development. Our next
meeting, scheduled for December 10, is to concentrate specifically on the north and '
south access boulevards. The boulevards' potential alignment, relationship to the TH 5
mainline, access to private parcels, and related issues are to be discussed at that time.
To this
o meet t s schedule, it is important that the north frontage road consulting contract be
initiated immediately. The contract's approval will assist the Task Force in
understanding the benefits and impacts likely from the roadway's location and traffic
function. It is imperative, however, that this work be initiated as soon as possible if the
December 10 Task Force meeting is to occur and technical information be available for
presentation.
Please contact me directly if you have any questions or comments pertaining to this
matter. Thank you for your cooperation.
