SUBJ: Receive Feasibility Study for Trunk Highway 5 South Frontage Road ( Galpin Boulevard to
McGlynn Drive) and Galpin Boulevard (Trunk Highway 5 to Timberwood Drive) and Area Trunk
Utilities - Project No. 93 -26
Attached is a feasibility study as prepared by Barton -A mans & Associates for the proposed construction of
roadway and trunk utility improvements in Section 18 in Chanhassen. The elements of the proposed project consist
of the construction of a south frontage (collector) road from Galpin Boulevard (County Road 19) east to McGlynn
Drive, the reconstruction and widening of Galpin Boulevard (County Road 19) from Trunk Highway 5 south to
Timberwood Drive, and the extension of trunk sanitary stover and watermain from their current terminus associated
with the Upper Bluff Creek Trunk Utility Improvement Proje at. No. 91 -17B. These trunk improvements were
petitioned by and will benefit nearly 200 acres of Jimd imminent for development consisting of the proposed
elementary school site, the Trunk Highway 5 Partnership property and the Heritage Development property. The
proposed improvements to Galpin Boulevard are consistent with Carver County's future function and design criteria
for this roadway. r "
The feasibility study describes in further detail the design elements for the proposed project, environmental impacts,
permits required, costs and proposed funding. The typical procedure on public improvement projects such as this
is for the City Council to receive the feasibility study document and have approximately one month's time to review
the document and become familiar with the proposed improvement project prior to holding a formal public hearing.
1
It is therefore recommended that the City Council formally receive the. feasibility study for the Trunk Highway 5
south frontage road (from Galpin Boulevard to McGlynn Drive) and Galpin Boulevard (CSAH 19) from Trunk
Highway 5 to Timberwood Drive and area trunk utilities, :Project No. 93 -32 and call for a public hearing at their
regular meeting on Monday, February 14, 1994.

DATE: September 8, 1993
SUBJ: Authorize Preparation of Feasibility Study for Trunk Highway 5 South Frontage
Road from Galpin Boulevard (County Road 19) east to Audubon Road
Project No. 93 -26
For sometime now, City staff has been involved in discussions with representatives of the Chaska
school district concerning the proposed elementary school site located in the southeast quadrant
of Trunk Highway 5 and Galpin Boulevard.' For more than a year, staff has also been receiving
inquiries about development of property located immediately east of the proposed school site and
east of the Timberwood subdivision. It appears that potential development of these properties
is now moving ahead as the City has been receiving concept plans for property in this area along
with petitions from property owners for public improvements. The petitions received from the
Trunk Highway 5 Partnership and the Heritage Development Company encompass approximately
137 acres of office industrial zoned property and approximately 24 acres of residential zoned
property.
The public improvements necessary for development of this area and the proposed school site
consist of an east/west collector road from Galpin Boulevard (County Road 19) east to Audubon
Road, storm sewer, trunk watermain and trunk sanitary sewer. The consultant engineering firm
of Barton- Aschmann & Associates has been working with the City's Highway 5 Corridor Task
Force to development the overall plan for the Highway S corridor including the adjacent north
and south access boulevard alignments. Needless to say, their background knowledge and history
surrounding this proposed roadway improvement is fairly extensive making them appropriately
suited to design this project. t ,
I have asked Barton- Aschmann to prepare a proposal to conduct the engineering feasibility study
for the installation of the south access boulevard collector street, storm drainage facilities and
trunk sanitary sewer and watermain utilities. Barton- Aschmann has provided an outline and
corresponding detailed description of the work tasks needed to be performed as a part of the

feasibility study along with a preliminary time schedule. It should also be noted that it is not yet '
known at this time whether an environmental assessment worksheet (EAW) will need to be
completed as a part of this feasibility process. Significant impact issues involving wetland '
impacts and the crossing of the east and west forks of Bluff Creek may require that an EAW be
completed to address these environmental issues prior to receiving permit approval from agencies
such as the DNR, Corps of Engineers and PCA. ,
Based on the extent of the project as defined at this time and the known available data, Barton -
Aschmann has estimated that the feasibility study will cost approximately $18,812. If an EAW '
should be necessary to be completed, the cost to perform this work task has been estimated at
$19,612. At this time, it is staff's recommendation that the City Council. authorize the
preparation of the feasibility study. If it is found that the EAW necessary, staff will notify the '
Council of such for authorization to proceed as outlined in this proposal with the cost estimate
as shown.
It is therefore recommended that City Council authorize the preparation of the feasibility study '
for the South Boulevard Access Road between Galpin Boulevard (County Road 19) and Audubon
Road along with the trunk utility improvements, Project No. 93 -26 and that Barton- Aschmann
be assigned as the project engineer for this project.

Re: South Access Boulevard Engineering Feasibility Study
'
Dear Mr. Folch: I
We are pleased to submit this proposal for professional engineering services in connection
with the development of a proposed elementary school in the southeast quadrant of TH 5 and '
Galpin Boulevard in Chanhassen, Minnesota. To adequately access the school site, the city
proposes to construct a portion of the south access roadway paralleling TH 5 on the south
from Audubon Road to Galpin Boulevard. The project also includes extension of utilities to '
properly serve the site. Barton- Aschman Associates, Inc. has developed a Scope of Services
based on our recent meeting with you to discuss the project and our experience in the area.
The work program will study the feasibility and cost for a 36 -foot urban section roadway in
an 80 -foot right -of -way with pedestrian amenities including water main and sanitary sewer
extensions in accordance with city comprehensive plans. '
The Scope of Services is as follows:
1.0 Data Collection/Inventory '
The consultant will develop a list of items such as plat maps, reports, development proposals,. '
surveys, aerial photos, etc. The city will provide the consultant with the requested items and
any additional information necessary to complete the project.
2.0 Basemappin '
It is anticipated that 1" = 100' aerial photography with contours will be utilized to develop the '
project basemapping. The City of Chanhassen obtained the aerial photography in 1989. A
field check will be conducted to verify that the aerials are up -to -date. The basemapping will '
be utilized for the project design.
3.0 Conceptual Roadw9v_M1ili1y Designs I
The south access boulevard will be designed as a two -lane urban roadway. Variables such as
pavement thickness, design speed, roadway width, etc. will be estimated during this phase of
the project. It is anticipated that one roadway alignment alternative will be considered from i

Galpin Boulevard to the east edge of the proposed school site. From the east edge of the
' school site to Audubon Road, it is anticipated that two alignment alternatives will be
considered.

Several trunk utility lines may follow the roadway corridor. Chanhassen's comprehensive
utilities plans will be analyzed as well as potential site developments to determine the size,
location, and construction timing of the utilities. It is assumed that capacity analysis for
sanitary sewer and water main utilities will be done by others.
4.0 Construction Cost
Based on the conceptual roadway and utility designs, construction costs will be estimated.
Costs will be adjusted in accordance with acceptable indexing methods for the anticipated
year of construction. Administrative, legal, and engineering costs will also be included in the
estimates.
Costs for right -of -way and easements will not be computed since those areas will be dedicated
for roadway and utilities through the platting process.
5.0 Feasibility Study
All roadway and utility designs, cost estimates, probable construction timing, land use and
development issues, etc. will be addressed and summarized in the Feasibility Study for the
project. Potential assessment costs will also be presented. The study will make a final
recommendation regarding the overall need and feasibility of the project.
6.0 Environmental Assessment Worksheet =Optional
This section presents the Scope of Services to complete the Environmental Assessment
Worksheet (EAW) and related permits for proposed south access boulevard between Galpin
Boulevard and Audubon Road.
The consultant anticipates that the more significant impact issues will involve wetland impacts
and crossings of the east and west forks of Bluff Creek. The EAW requires information on
type, size, location, and impacts (magnitude and significance) to both of these natural features.
Our focus will be those environmental issues, such as wetlands and floodplain encroachment,
that have a direct bearing on the Record of Decision (ROD).
EAW Process
The EAW process will begin with data collection to prepare the EAW and end with the
Record of Decision containing specific findings of fact that support the decision on the need
for an EIS to be prepared. Responsibility for steps in the process are highlighted in Table 1.

6.1 Data Collection
Data to be collected includes specific information on the proposed alignment for the south
access boulevard. Field reconnaissance of the project will be done and contacts made to the
appropriate regulatory and planning agencies including USCOE, USFWS, MnDNR, MPCA,
MHS /SHPO, and Riley and Bluff Creek Watershed District.
The EAW requires analysis to address 32 specific items comprising the review document.
The consultant will collect the bulk of the data, addressing items dealing with project design,
land use and zoning, natural resources, mapping, and traffic and noise and air quality analysis
The remainder of the data for the EAW will be provided by the city and includes project
maintenance plans, traffic projection figures (volume, peak hours, distribution), and past and
future related developments (including the relationship of this project to the existing network
in the area and anticipated future roadways). After all data is available, the EAW will be
prepared in accordance with the Minnesota Environmental Quality Board (EQB) rules for this
type of document.

SUBJ: Select Preferred Alignment Alternative for Galpin Boulevard South of Trunk Highway 5; Amend
Feasibility Scope - Project No. 93 -26
Earlier this fall the City commissioned the consulting firm of Barton- Aschman Associates, Inc. to conduct a
feasibility study for the Trunk Highway 5 south frontage road between Galpin Boulevard and Audubon Road and
area trunk utility improvements, Project No. 93 -26. An important road element of this project is the improvement
of Galpin Boulevard from Trunk Highway 5 south to Timberwood Drive. During the process of conducting the
feasibility study, Barton- Aschman has identified 2 alignment' alternatives for this segment of Galpin Boulevard.
Alternative No. 1 basically proposes to load the road widening area on the east side of Galpin Boulevard.
Conversely, Alternative No. 2 proposes the widening to be loaded on the west side. A cost estimate /impact
summary matrix has been prepared for each of the two alteratives ;.`:Alternative No. 1 (widening along the east side)
is further differentiated into three options to deal with the roadway `side slope, i.e. retaining wall, 2:1 back slope and
3:1 back slope. From a purely economic standpoint, Alternative No. 1 implementing a 3:1 roadway back slope is
the recommended choice; however, the engineer and staff wanted to.present these alteratives and corresponding
information to the Council for further discussion and confirmation
Selecting the preferred alignment alternative is important at this point in time in order to allow preliminary surveying
work and the geotechnical investigation to be accomplished in a timely manner and corresponding information
included in the study report.
Unless pertinent questions or concerns are raised by Council which may require further investigation, it is staffs
recommendation to select Alternative No. 1 as the preferred roadway alignment for Galpin Boulevard from Trunk
Highway 5 south to Timberwood Drive as a part of the overall south frontage road Project No 93 -26.

SUBJECT: Galpin Boulevard (CSAH 19) Reconstruction Alternatives
property east of Galpin Boulevard and south of TH 5 (see Figure 1). A new frontage road
As discussed at our November 16, 1993, meeting, Barton - Aschman has developed and
'
analyzed various alternatives for'the reconstruction of Galpin Boulevard (CSAH 19)
,
between Timberwood Drive and Trunk Highway 5. This memorandum and its
1.
attachments briefly describe the alternatives and their comparative costs and impacts. It
is anticipated that the Chanhassen City Council will select an alternative at its
,
December 13, 1993, meeting.
The information presented in this memorandum will also be included in the forthcoming '
TH 5 South Frontage Road Feasibility Study.
Overview
,
Independent School District 112 is proposing to construct a new elementary school on the
property east of Galpin Boulevard and south of TH 5 (see Figure 1). A new frontage road
is proposed along the south side of the school site. Trunk Highway 5 is scheduled for
'
upgrading to a four -lane divided roadway in the late 1990s.
Galpin Boulevard will be reconstructed to two lanes in each direction with left-turn lanes .
1.
along the west side of the school site. From south of the school site to Lyman Boulevard,
Galpin Boulevard will be widened to 52 feet; it is likely that pavement striping would
limit traffic to one through lane in each direction.
Occupation of the elementary school is scheduled for the fall of 1995. The proposed
roadway and utility improvements including the south frontage road along the south side
of the school site, reconstructed Galpin Boulevard between Timberwood Drive and TH 5,
and all utilities must in -place at that time.
,
Alternatives for the reconstruction of Galpin Boulevard between Timberwood Drive and
TH 5 have been developed and are illustrated on Figures 1 through 4. Table 1
summarizes the comparative cost estimates and the impacts of the alternatives. Figure 5
'
shows the existing and proposed profiles of Galpin Boulevard, which are the same for both
alternatives.
PARSONS
TRANSPORTATION GROUP
I
BAATON- ASCHMAN ASSOCIATES', INC.
Alternatives
' Under Alternative 1 (Figures 1 and 2), Galpin Boulevard would be widened to the east
along the school site and to the west along Timberwood Estates. This alternative
minimizes impacts to the three existing residences along the west side of Galpin
Boulevard and to the mini golf/driving range business northwest of the TH 5 /Galpin
Boulevard intersection. Lowering of the Galpin Boulevard profile (as shown on Figure 5)
will require that the front yards of the residences be re- landscaped. The driveways will
also need to be reconstructed.
Some impacts occur in the northwest corner of the Timberwood Estates. Section B -B on
Figure 2 shows three grading options for the area. Table 1 summarizes the comparative
costs and impacts of the grading options.
Under Alternative 2 (Figures 3 and 4), Galpin Boulevard would be widened to the west
along the school site and along Timberwood Estates. However, the alignment would be
adjusted at TH 5 to minimize impacts to the mini golf/driving range business north of
TH 5.
The three existing residences would be purchased or condemned as roadway right -of -way
under this alternative. The middle property is currently for sale. The listed price was
' $118,900 as of November 18, 1993. An assumed cost of $120,000 for each property was
utilized in the comparative cost estimate.
' Recommended Alternative .
It is recommended that Alternative 1 be selected because of its substantially lower right -
of -way costs. The 3:1 backslope grading option of Alternative 1 is also recommended.
' Retaining wall costs are eliminated and a stable groundslope is provided. The two fir
trees that would be impacted seem to be in marginal condition. Some scrub growth would
have to be cleared. However, the 36 -inch mature oak tree would be preserved.
