REQUESTED ACTION
Hold the public heating and authorize preparation of plans, and specifications for
Project No. 04-02.
DISCUSSION
Attached is a final draft of the feasibility study for this project. The following
changes have been made from the draft previously received:
Discussion of the South Shore neighborhood has been removed from this
feasibility study for budget reasons. This area will be reconsidered at a
future time.
Indirect costs were left out of the cost estimates in the previous study.
Indirect costs include financial, legal, administration, and engineering
costs. Both the cost estimate and the assessment rolls have been adjusted
to include these costs.
3. Tables have been added to better show the funding for this project.
4. Minor typographical errors have been corrected.
Staff recommends that to reduce confusion, Council call property owners by street
for the public hearing with a brief introduction of the existing condition and
proposed improvements by staff as each street is called.
Market Boulevard (between Highway 5 and W, 78th Street)
The existing surface shows moderate deterioration evidenced by cracking
both transverse (across the width) and longitudinally (lengthwise) on the
street. The consultant is recommending the full width of the street be
milled an average of 1Va" and a bituminous overlay be placed to
rehabilitate the existing surfacing and extend the life of the street. Cracks

that extend through the milled section will be sealed prior to the overlay.
Traffic signal loop detectors at Highway 5 and W. 78th Street will need to
be removed and replaced as part of the project. The existing lighting and
signals at the railroad meet current standards; however, the rubber-matted
material between the railroad tracks is nearing the end of its functional
life. A cost to replace this mat has been included in the cost estimates for
the project.
Great Plains Boulevard (between Highway 5 and W. 78th Street)
The pavement in this area also shows moderate deterioration similar to
that found on Market Boulevard. The consultant is recommending the full
width of the street be milled an average of 1V2" and a bituminous overlay
be placed to rehabilitate the existing surfacing and extend the life of the
street. Cracks that extend through the milled section will be sealed prior
to the overlay. Traffic signal loop detectors at Highway 5 and W. 78th
Street will need to be removed and replaced as part of the project. The
existing lighting and signals at the railroad meet current standards;
however, the rubber-matted material between the railroad tracks is nearing
the end of its functional life. A cost to replace this mat has been included
in the cost estimates for the project.
West 78th Street (between Market Boulevard and Great Plains Boulevard)
The pavement in this area shows signs of deterioration, but still appears
structurally sound. The consultant is recommending the full width of the
street be milled an average of 1V2" and a bituminous overlay be placed to
rehabilitate the existing surfacing and extend the life of the street. Cracks
that extend through the milled section will be sealed prior to the overlay.
In addition, slope and curb adjustments should be done at the same time to
improve storm drainage in the area. Traffic signal loop detectors at
Market Boulevard, Laredo Drive, Great Plains Boulevard and Highway
101 will need to be removed and replaced as part of the project.
At the same time this project is done, the unused driveway openings into
the cemetery will be removed and replaced with curb and gutter similar to
that currently in place.
West 79th Street (between Market Boulevard and Great Plains Boulevard
and Great Plains Boulevard to the cul-de-sac)
These roads are not currently on the City's Municipal Street Aid System
(MSAS). The section between Market Boulevard and Great Plains
Boulevard qualifies to be placed on the MSAS system in which case, staff
recommends that the project be pursued at this time. The section between
Great Plains Boulevard and the cul-de-sac do not meet the criteria for
MSAS inclusion.

The pavement between Market Boulevard and Great Plains Boulevard
shows evidence of moderate deterioration similar to that on the other
streets. The section approximately 450' east of Market Boulevard shows
significant failure that appears to have been caused by the storm sewer
pipe heaving, possibly due to poor bedding of the pipe during installation.
The pavement in this area will need to be removed and the storm sewer
pipe reinstalled properly to minimize potential damage from future frost
heave.
The section east of Great Plains Boulevard was widened and resurfaced in
1991 and could be delayed until future construction.
The consultant is recommending the full width of the street be milled an
average of lY2" and a bituminous overlay be placed to rehabilitate the
existing surfacing and extend the life of the street. Cracks that extend
through the milled section will be sealed prior to the overlay.
In addition, it has been recommended that a sidewalk be considered along
the north side of W. 79th Street. Staff will work with the property owners
to determine if this is feasible and desirable to all of the impacted property
owners and if so, prepare an addendum to the feasibility study with
revised assessments for the impacted property owners as per the City's
Assessment Practice.
FUNDING
This project is proposed to be funded with a combination of MSAS State-Aid,
State Turn-Back Funds, and assessments.

1.0 Conclusions and Recommendations
1.1
Conclusions
Based upon current investigation in the
concluded that:
study area, it has been
The streets in the study area have not outlived their functional life
and do not require full reconstruction. However, they do require a
significant amount of maintenance to extend the serviceable life of
the respective roadways.
The present age of the roadway, proposed traffic volumes, and
natural weathering factors indicate that a mill and overlay should
be performed on Market Boulevard, Great Plains Boulevard, and
West 78th and 79th Streets.
Surface drainage problems exist at several locations in the project
area, and are addressed within the context of this report. Sporadic
concrete curb and gutter replacement and catch basin
reconstruction is necessary throughout the entire project area.
o
There is adequate pedestrian access throughout a majority of the
project area. However, 5-foot sidewalk connections are proposed
on the east-side of Market Boulevard between Highway 5 and
West 79th Street and on the west-side of Great Plains Boulevard
between West 79th Street and the existing sidewalk to the north.

4. Valley gutters are proposed to facilitate improved drainage at
driveways and/or intersections with relatively flat grades.
o
SEH has identified locations where the existing concrete curb and
gutter has deteriorated to a condition that warrants removal and
replacement due to frost heave, settlement, snow plow impacts,
etc.
6. The improvements are necessary, cost-effective, and feasible.
Recommendations
It is recommended that:
1. The report be reviewed by the City Council, staff, and financial
advisors.
2. Reconstruction of the streets in 2004 MSA Street Improvements
project area should proceed at an estimated cost of $961,501.63.
3. The project be financed with MSA funds, special assessments, and
State Turnback funds.
The City Council pledge MSAS funding of SIM and State
Turnback funding of $250,000 to fund the City's share of the
project.
o
Meet with adjacent residents and property owners to discuss the
existing conditions, such as drainage issues, parking/no parking
locations and/or pedestrian access, and identify the proposed
improvements.
6. The City should continue budgeting funds to finance future street
maintenance costs.
7. Construct the improvements as proposed in this report.

Introduction
Background Information
A report on feasibility for the 2004 MSA Street Improvements was
ordered by the Chanhassen City Council in May 2003. The study area
is shown on the following map.
The streets included in this study are Market Boulevard (MSA), Great
Plains Boulevard (MSA), West 78th Street (MSA and State Turnback),
and West 79th Street (local street). This project is considered part of
the City of Chanhassen's ongoing annual street improvement program.
Before initiating this feasibility study, SEH
work plan to outline the scope of the study.
analyzed in this feasibility study are:
coordinated a detailed
The work components
1. Examine the existing condition of the bituminous pavements in the
project area.
2. Analyze the existing concrete curb and gutter for cracking and/or
settlement and quantify locations where replacement is necessary.
3. Identify 'fiat spots' or other locations in the roadway with
inadequate drainage which lead to street ponding.
4. Identify catch basin structures that have heaved or settled. Propose
reconstruction strategy for these locations.
5. Identify existing sidewalk locations, pedestrian accessibility, and
system continuity, and suggest improvements where necessary.
o
Determine locations where safety improvements may be made,
such as the addition of surmountable medians, removal of unused
access points, etc.
7. Examine the feasibility of installing a drain tile system to serve
areas where deemed necessary.
8. Analyze the existing railroad crossings at Great Plains and Market
Boulevard and determine if any improvements are necessary.
The report figures are located at the end of this report.

3.2
Existing Conditions
Pavement
The streets in the project area were either originally constructed or
reconstructed in a span of time beginning in the mid 1970s to the early
1990s. For this reason, the pavement conditions vary from street to
street. However, there were no locations in the project area that
necessitated complete reconstruction of the roadway.
The present pavement surfaces show signs of only moderate
deterioration. A site visit to the project area confirmed that a majority
of the street pavements are in relatively good condition. SEH analyzed
the streets in the project area and used the following conditions and
criteria for evaluation:
Bituminous pavement is designed to last 25 to 30 years, based
upon the latest construction and maintenance procedures used in
the City of Chanhassen.
Extensive cracking was not noted in any location within the study
area. Such cracking, also identified as 'alligator cracking' is a sign
of imminent structural failure and the last step prior to a pothole
developing. The streets in the study area only showed signs of
minor transverse and longitudinal cracking, a problem easily
solved with a proactive maintenance policy.
In specific locations, improperly bedded pipes beneath the
roadway will result in unintentional 'speed bumps' in the road
surface. In these locations, the pipes will need to be excavated and
the road reconstructed to provide a suitable driving surface.
In some locations, the streets have settled, resulting in 'bird baths'
after rainfall or snow-melt events. In addition, the crown of the
street has subsided in some locations, allowing surface water
runoff to flow randomly down the street and not into the gutter.
Both of these conditions contribute to more water soaking into the
underlying soils through cracks in the surface. The water will
subsequently weaken the soils, which will eventually lead to
structural failure if not corrected by restoring positive drainage.
Progressively increasing traffic volumes and weathering were
other factors that contribute to the ongoing deterioration of the
pavement surface.
Sidewalks
A rather extensive sidewalk system presently exists in the project area.
Pedestrian access is provided on at least one side, and in several cases,
both sides of the streets.
Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00
Chanhassen, Minnesota Page 5
3.3
3.4
At present, there are some locations in the project area that are
conducive to sidewalk connections and pedestrian flow, however, no
sidewalk exists. These areas have been identified on the east side of
Market Boulevard between Highway 5 and 79th Street, and on the west
side of Great Plains Boulevard from 79th Street north to the existing
sidewalk.
Most sidewalk connections with the streets in the project area utilize
ADA-compliant pedestrian ramps for handicapped access. However,
the sidewalk on the north side of 79th Street, approximately 600 feet
east of Market Boulevard does not presently have pedestrian ramps at
the driveway intersections.
Right-of-Ways and Easements
The streets within the study area are built approximately in the center
of the right-of-ways (ROW). The majority of the ROW in the project
area is between 70 and 100 feet wide. As a majority of the work
proposed in this feasibility study will occur on the existing roadway
surface, the ROW corridor will be sUfficiently wide for all of the work
proposed in this study.
Drainage
Two types of drainage have an impact in the study area. The first type
- surface water runoff- results from rainfall or snow melt. The
project area relies heavily upon the concrete curb and gutter section to
transport water catch basins and on to the adjacent drainage ponds.
Unexpected settlements in the curb and flattening of the road profile
leads to the creation of 'bird baths' on the road surface where surface
water runoff does not reach the intended catch basins.
Consultation with City staff and a subsequent field investigation
identified the following potential surface water runoff problems:
Potential drainage problems due to heaved storm sewerthPipe and
catch basins near the existing low point on 79 Street,
approximately 400 feet east of the intersection with Market
Boulevard.
2. Indications of standing water at the intersection of Market
Boulevard and Pauly Drive.
3. Several individual low spots in the outside and median gutters on
78th Street between Market Boulevard and Great Plains Boulevard.
4. Standing water at the east-side of the 78th Street and Highway 101
intersection.

Chanhassen, Minnesota Page 6
o
Large tributary area draining to the Lotus Lake Park parking lot, in
addition to erosion problems at the storm sewer inlet on the
northeast comer of the parking lot.
The second type of drainage affecting the study area is subsurface or
groundwater flow.
At present, we have no soil borings in the project area to confirm the
elevation of the water table, or the type of soils encountered in the
area.
3.5 Utilities
The sanitary sewer and water main systems have been in place since
the mid 1970s to the late 1980s. Several utility improvement projects
have been completed in the project area since the time of their original
construction. The existing sanitary sewer throughout the project area
is periodically televised, and initial discussions with City staff have
indicated no significant issues at this time. There are no known
problems with the water main system that needs to be corrected with
the street reconstruction.
The condition of sanitary sewer services from the main to the houses is
not known at this time. Although there have been no issues identified
by City staff or property owners at this time.
Electric, telephone, and cable TV lines in the study area are mostly
buried outside of the street pavement area. There are some overhead
utilities in the project area, however, they should not create any
problems with any of the proposed improvements identified in this
study.
Gas mains and services are buried under the street pavement and no
significant problems have been identified with these lines.
3.6 Concrete Curb and Gutter
A large majority of the concrete curb and gutter on Market Boulevard,
78th Street (west of Great Plains Boulevard), and Great Plains
Boulevard is a modified version of B612 (median) and B618 (outer
curb). The modified version is different from the typical variety
because it has a thicker section of concrete at the top of the curb. A
normal B-type curb is six inches thick at the top and eight inches thick
at the gutter line. The curb section on the aforementioned streets is
approximately 10 inches thick at the top and 12 inches thick at the
gutter. This thicker section has provided for additional structural
strength as much of this curb section is in very good condition and
shows very few mid-panel cracks.
However, as found at several locations within the project area, the
modified B612/B618 curb and gutter sections have settled/faulted
Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00
Chanhassen, Minnesota Page 7
adjacent to a few of the existing catch basin structures on Market
Boulevard.
The concrete curb and gutter on 78th Street, east of Great Plains
Boulevard, and 79th Street, east of Great Plains Boulevard is a standard
B612/B618. Although this curb is in relatively good condition, some
sections have settled/heaved near the existing catch basins. In
addition, a minimal amount of curb has shown signs of mid-panel
cracking.
The curb on 79th Street, between Market Boulevard and Great Plains
Boulevard is a surmountable D-type curb. The curb in this location
has shown some signs of minor deterioration and settlement near the
existing catch basins. In addition, there is an incomplete valley gutter
crossing 79th Street at Great Plains Boulevard.
It should also be noted that on both Market Boulevard and Great Plains
Boulevard approaching Highway 5, and on 78th Street approaching
Highway 101, the concrete curb and gutter section transitions into a
B624 type, as is typical on Mn/DOT projects.

Proposed Improvements
Pavement
The proposed improvements to the pavement sections vary by location
for this project.
A common preventative maintenance approach for roads with minor to
moderate deterioration is a mill and overlay procedure. In this
process, a specified depth of the existing pavement is removed, or
milled off. Upon removal of the existing pavement surface, all of the
remaining cracks are sealed to prevent moisture penetration into the
roadway subgrade. A new bituminous asphalt overlay is then placed
to seal the roadway and match existing grades. This maintenance
process is used to provide a new driving surface for the roadway while
improving driver 'rideability' and rebuilding the centerline crown to
facilitate better drainage.
A 1½-inch depth mill and bituminous overlay is proposed for the
following segments:
1. Market Boulevard- between Highway 5 and 78th Street
2. Great Plains Boulevard- between Highway 5 and 78th Street
3. West 78th Street - between Market Boulevard and Great Plains
Boulevard
4. West 79th Street - betWeen Market Boulevard and Great Plains
Boulevard. This work could be delayed for a couple of years
as this section cannot be added to the City's MSA system.
However, there is a potential cost savings by combining this
project with the larger Market Boulevard, Great Plains
Boulevard, and West 78th Street project.
5. West 79th Street- from Great Plains Boulevard to the cul-de-
sac terminus. This section does not qualify for inclusion in the
City's MSA system, which means the City share of the project
would need to withdrawn from the General Fund. This section
of roadway could be delayed for a couple of years, and
combined with a future project funded with General Fund
dollars. However, there is a potential cost savings by
combining this project with the larger project, especially if
West 79th Street is completed in 2004.
In locations where the pavement has deteriorated to a more significant
extent, the existing pavement and roadbed will be ground into a
recycled base material that will be used under the proposed pavement

structure. This type of improvement is proposed only for spot repairs
on the above streets.
5.1.1 Market Boulevard
In general, the pavement surface in this segment shows evidence of
moderate deterioration. This is characterized by minor transverse and
longitudinal cracking. Based upon our field observations and our
study of the existing and proposed traffic volumes, we recommend a
full-width, 1½-inch mill and bituminous overlay as the appropriate
rehabilitation strategy. In addition, any cracks remaining upon
completion of the milling operation will be sealed to minimize any
moisture penetration to the subgrade material.
The traffic signal loop detectors at the intersections of Market
Boulevard with Highway 5 and 78th Street are typically removed
and/or significantly damaged during the milling operation. The loop
detectors will be replaced in conjunction with the paving of the
bituminous wear course.
The existing pavement markings and traffic control have been
documented during our field investigation. These markings will be
further analyzed during the design phase of the project to determine if
any revisions to the existing pavement markings are necessary. The
existing pavement markings will be replicated and replaced with new
epoxy pavement markings upon completion of the final wear course.
An analysis of the Twin City and Western Railroad crossing with
Market Boulevard has determined that the existing lighting and
crossing signals are adequate for the intersection. However, the
rubber-matted material between the railroad tracks is nearing the end
of its functional life and should be replaced in conjunction with this
project. An estimated cost for the removal and replacement of the
rubber mat and related materials at the crossing, has been included in
the overall cost estimate as found in the Appendix.
5.1.2 Great Plains Boulevard
The pavement surface in this segment also shows evidence of
moderate deterioration. The transverse and longitudinal cracking is
similar to that found on Market Boulevard. Based upon our field
observations and our study of the existing and proposed traffic
volumes, we recommend a full-width, 1½-inch mill and bituminous
overlay as the appropriate rehabilitation strategy. The remaining
cracks will be sealed to minimize any moisture penetration to the
subgrade material.
The traffic' signal loop detectors at the intersections of Great Plains
Boulevard with Highway 5 and 78th Street will be removed and/or
significantly damaged during the milling operation. The loop

bitmninous wear course.
The existing pavement markings and traffic control have been
documented during our field investigation. These markings will be
further analyzed during the design phase of the project to determine if
any revisions to the existing pavement markings are necessary. The
existing pavement markings will be replicated and replaced with new
epoxy pavement markings upon completion of the final wear course.
An analysis of the Twin City and Western Railroad crossing with

of its functional life and should be replaced in conjunction with this
project. An estimated cost for the removal and replacement of the
rubber mat and related materials at the crossing, has been included in
the overall cost estimate as found in the Appendix.
West 78th Street
The bituminous surface in this location shows signs of deterioration,
but the pavement appears to be structurally sound. We recommend a
full-width, 1 ½-inch mill and bituminous overlay, with related Crack
repair, as an appropriate rehabilitation strategy in this location, in
conjunction with slope and curb adjustments to improve storm
drainage. This will be discussed in greater detail in Section 5.4
Drainage, of this report.
Traffic signal loop detectors at the intersections of 78th Street with
Market Boulevard, Laredo Drive, Great Plains Boulevard and
Highway 101 will be removed and/or significantly damaged during the
milling operation. The loop detectors will be replaced in conjunction
with the paving of the bituminous wear course.
On the segment of 78th Street, approximately 700 feet east of the
intersection with Great Plains Boulevard, there are several unused
driveway aprons on the south side of the roadway that were originally
used to access the cemetery adjacent to 78th Street. These aprons will
be removed in conjunction with this project, and replaced with B618
curb and gutter.
The existing pavement markings and traffic control have been
documented during our field investigation. These markings will be
further analyzed during the design phase of the project to determine if
any revisions to the existing pavement markings are necessary. The
existing pavement markings will be replicated and replaced with new
epoxy pavement markings upon completion of the final wear course.

5.1.4
West 79th Street
There are two segments of 79th Street studied within the context of this
report. The first is bound by Market Boulevard on the west and Great
Plains Boulevard on the east. The other segment begins at Great
Plains Boulevard and extends east and terminates in a cul-de-sac
approximately 700 feet to the east.
On the segment between Market Boulevard and Great Plains
Boulevard, the most significant problem with the pavement exists
approximately 450 feet east of Market Boulevard. A poorly bedded
storm sewer pipe has heaved into the roadbed and created a 'hump' in
the pavement surface.
The pavement in this section will need to be removed and the storm
sewer pipe and structures will need to be salvaged and replaced on
appropriate bedding material to minimize any potential damage from
frost heave. This entire procedure will necessitate the complete
reconstruction of about 200 feet of roadway on 78th Street.
The remainder of this segment has shown moderate signs of fatigue in
the form of transverse and longitudinal cracking of the driving surface.
We recommend a full-width, 11A-inch mill and bituminous overlay,
with related crack repair, that matches into the reconstruction segment.
The segment east of Great Plains Boulevard is in relatively good
condition. According to the as-built plans on file with the City, this
segment was widened and resurfaced in 1991. The low traffic
volumes and recent improvements have contributed to the limited
deterioration on this segment and have minimized the need for
rehabilitation at this time.
However, due to the adjacent construction proposed in this study and
the timeline for future maintenance activities in this location, the City
may elect to rehabilitate this segment of 79th Street at this time. If so,
a 1½-inch mill and overlay would preserve the existing pavement
structure for up to ten years.
5.2
Sidewalk
Upon inspection of the existing sidewalks adjacent to the roadways in
the study area, they have been found to be in relatively good condition.
Therefore, a majority of the proposed improvements related to the
sidewalks consist of the construction of new sidewalks and/or
modifying access to an existing sidewalk.
Sidewalks are not required by MSA standards, but are eligible for
MSA funding if included. Thus, a 5-foot concrete sidewalk will be
constructed on the east-side of Market Boulevard from Highway 5 to
79th Street. A sidewalk will also be constructed from the existing
pedestrian ramp in the northwest quadrant of the intersection of Great

Chanhassen, Minnesota Page 13

5.4.1
Plains Boulevard and 79th Street, extending north to connect with the
existing sidewalk. The proposed sidewalk sections will consist of 4
inches of aggregate base material and 4 inches of concrete pavement.
On the north side of 79th Street, approximately 800 feet east of Market
Boulevard, there is a relatively new sidewalk on the north side of the
street. This sidewalk has been constructed to the back of the existing
barrier curb, not allowing for handicapped access. The existing barrier
curb will be removed, and a ADA-compliant pedestrian ramp will be
constructed on the east and west end of the sidewalk.
Rights-of-Ways and Easements
All proposed improvements identified in this feasibility study should
be within the existing right-of-way (ROW) limits. No temporary or
permanent easements are anticipated at this time.
Drainage
The reuse of the existing storm water collection system is a principle
component of the proposed improvements identified in this study.
However, some of the existing catch basins have heaved into the
surrounding concrete curb and gutter, creating drainage problems and
allowing storm water to penetrate the subgrade soils, creating
additional problems. Proposed correction of this problem will include
adjusting the catch basin casting heights and/or curb and gutter
replacement, where necessary.
Other drainage improvements will be focused on alleviating areas with
poor drainage, where existing ponding of runoff is evident. These
improvements will include re-grading the roadway where necessary
and the installation of concrete valley gutter at selected intersections to
convey runoff to the existing catch basins.
Market Boulevard
Preliminary analysis has identified the intersection of Market
Boulevard with Pauly Drive as a location that is relatively flat. Our
field investigation and subsequent topographic survey has indicated
that this location would benefit by the construction of an additional
catch basin structure on the east and west side of the intersection to
provide adequate drainage. These catch basins would be tied into the
existing system, which ultimately drains into the storm water pond in
the northwest quadrant of Market Boulevard and Highway 5.
In addition, the existing valley gutter on both sides of the intersection
should be removed, the subgrade adjusted to drain to the new catch
basin structures, and replaced in order to facilitate the flow of the
storm water.

Chanhassen, Minnesota Page 14
5.4.2
Great Plains Boulevard
There were no significant drainage problems identified on Great Plains
Boulevard.
5.4.3
West 78th Street
The two commercial driveways on the north side of 78th Street
between Laredo Drive and the west intersection of 78th Street with
Great Plains Boulevard would benefit by the addition of a valley gutter
across the driveway. At present, there is evidence of ponding in the
gutter line on both of these driveways.
In addition, there are several low spots in the outer and median gutter
on 78th Street between Market Boulevard and Great Plains Boulevard.
Most of these low spots appear to be caused by curb that has heaved
and/or settled. These curbs can be repaired either by 'mud-jacking'
the existing curb, or removing and re-pouring the unsuitable curb
sections.
Moving east from the intersection with Great Plains Boulevard, there
are three driveway entrances to the cemetery on the south side of 78th
Street that are presently unused. These driveway aprons will be
removed and replaced with standard B618 curb and gutter.
The most troubling drainage issue on 78th Street occurs immediately
west of the intersection with Highway 101. Existing drainage in the
north curb-line of 75th Street is conveyed to the existing catch basin
approximately 150 west of the intersection. However, any storm water
to the east of this catch basin drains to the northwest corner of the
intersection. As it pools in this gutter, it eventually overflows across
78th Street to the south and pools in the north gutter of the intersection
'pork-chop' island. Drainage pools in this location until continuing on
to the south, across the 'free-right' turn lane, and into an existing catch
basin.
Additional discussion with the City is necessary to determine the
extent of the existing problem in this area. A field investigation has
determined that ponding does occur in each of the areas identified
above, however, the typical depth and duration are not known at this
time.
Additional as-built plans have presently been requested from Mn/DOT
for this location in order to ascertain invert elevations on the existing
catch basins. One proposed solution would add a catch basin structure
in the northwest comer of the intersection and connect it to the catch
basin 150 feet to the west. However, the as-built information will be
necessary to determine if this is feasible.
Upon further discussion with City staff, SEH will evaluate if any
improvements are necessary in this location and additional alternatives
will be evaluated during the design phase of this project.

West 79th Street
The only significant drainage problem identified on 79th Street occurs
at the low point approximately 400 feet east of the intersection with
Market Boulevard. The existing storm sewer pipe crossing 79th Street
and extending to the storm water pond to the south, has heaved into the
existing pavement creating an 'unintentional' speed bump in the road.
This pipe, subgrade, and related catch basins will need to be excavated
and replaced with granular bedding material, compacted, and replaced.
If possible, the profile will be adjusted to lower the Iow point in this
location, which will necessitate the reconstruction of approximately
200 feet of roadway to accommodate the profile revision.
Lotus Lake Park Drainage
A major drainage issue has been identified in the Lotus Lake Park
parking lot. A large amount of runoff from the project area ends up in
the parking lot, as it is the low point for a majority of the development.
Additional discussions with City staff are necessary to determine
whether Lotus Lake drainage improvements will be constructed in
conjunction with this project.
Utilities
Due to the present condition of the sanitary sewer and water main in
the project area, no improvements to the public utilities are proposed at
this time.
Private utilities such as electric, telephone, gas, and cable TV, will be
notified of the impending potential improvement project and any
proposed improvements to those facilities will be coordinated with the
appropriate agency and constructed prior to the placement of the
bituminous wear course and/or restoration of the sod.
Concrete Curb and Gutter
A detailed field review of the existing concrete curb and gutter
conditions was performed to identify replacement areas with the
objective of preserving as much existing concrete curb and gutter as
possible. The criteria used to determine unacceptable curb was based
on the following:
1. The curb needed to be removed if one major defect was found on a
section, e.g., a faulted crack.
2. The curb needed to be removed if three minor defects were found
on a section, e.g., several tight cracks and a scalloped curb face.
Approximately five percent of the existing B-type curb was found to
be in need of repair or replacement. The deteriorated curb was largely
Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00
Chanhassen, Minnesota Page 16
in the vicinity of the existing catch basins where the curb and gutter
section has heaved/settled.
A larger percentage of the D-type surmountable curb was found to be
in poor condition. From our estimates, as much as 15% of the D-type
curb on 79th Street between Market Boulevard and Great Plains
Boulevard should be removed and replaced.
The replacement curb and gutter will significantly improve drainage
flow, maintain structural support to reduce edge deterioration, and
continue to protect boulevards from traffic and snow plowing.

Current Assessment Practice
CITY OF CHANHASSEN
ASSESSMENT PRACTICE
This Assessment Practice is intended to provide direction to City Staff in preparation of assessment roles to ensure fair and
consistent treatment of all properties within the City of Chanhassen.
MAINTENANCE:
(Pothole filling, Patching, crack sealing, seal coat.)
Maintenance costs are not assessed to abutting property owners. Maintenance costs are financed
through the City's Annual Budget process.
REHABILITATION:
(Repair of problem areas to full depth, Milling of edge or full width of existing pavement, Repair to existing catch basins and/or
curb and gutter, Pavement Overlay)
Rehabilitation costs are assessed using the following formula:
Total Project Cost:
60% Paid by City
(City share may be MSA, General
Fund, TIF, Federal or State Grants,
etc.)
40% Assessed to
abutting Property
Owners
Residential properties that abut collector or commercial streets shall be assessed using the same
formula, however, the assessments shall be reduced to be equivalent to a typical 3 I' residential
street section.
RECONSTRUCTION:
(Removal of existing street and construction of new street,. May include sanitary sewer or watermain work, May recycle the
existing asphalt as gravel base)
Reconstruction costs are assessed using the same formula as Rehabilitation.
NEW CONSTRUCTION:
(Construction of new street or utilities or a significant upgrade from the previous facilities, i.e. a 4-lane street replaces an
existing 2-lane.)
New Construction will be assessed 100% to the benefiting properties.
NOTE:
If a feature (sanitary sewer, water, curb and gutter, etc.) that did not previously
exist is added during a rehabilitation or reconstruction, the cost of that item is
treated as new construction with the remaining project costs being treated as
rehabilitation or reconstruction.
WORK DONE BY CITY CREWS:
Work done by City Crews may be maintenance, rehabilitation, or new construction. This work is
not typically assessed. Exceptions would include work associated with an assessment agreement
signed by the property owner and approved by the City Council and work specifically authorized
by the City Council to be done by City Crews and assessed to the abutting properties.
