Smithtown Road Improvements
City Project No.
WSB Project No. 1074-58
1. Executive Summary
Smithtown Road has experiencf pavement deterioration to the point that normal
maintenance activities are no longer sufficient. The City of Shorewood has requested
that WSB & Associates prepare a feasibility report exploring the costs and benefits of
street rehabilitation methods. ~
L ~",,"'~
This request investigates two methods, namely overlaying the roa or~eClamation.
Overlaying simply places a 1-2" layer of bituminous pavement over the existing
asphalt. Reclamation consists of grinding off the existing paving and mixing it with the
existing gravel to make a good base, and then paving the road with 4" of new asphalt.
The city also requested that the addition of gravel shoulders be explored.
The reclamation option is more expensive (approximately 62% more than an overlay),
but provide~~e permanent, longer lasting road. An overlay typically extends the
life of a road ~years while a reclaiming would extend the life 12-15 years. In
addition, with a reclamation project, there is more opportunity to correct minor
deviations in the grade and slope.
The overlay option is estimated at $342,000 while the reclamation option is $555,000.
The addition of gravel shoulders would cost approximately $80,000 for one side or
$160,000 for two.
This report recommends the reclamation option with gravel shoulders on at least one
side.
The project would be funded 100% by the Municipal State Aid account.
The timing of the project would be determined by the resolution of the right-of-way
issues. If those can be resolved quickly, the project could be designed and constructed
in 2001, but it is more likely to be completed in 2002.

2.1. Authorization. / / I ~ / I
NtIt4/J. ,,;em ~
The City of Shore~od has authorized the preparation of a feasibility report for
the mmiJ.o~! ~~d v. ",~ld'j of that segment of Smithtown Road between the west
city limits to Country Club Road. The project is anticipated to be constructed as
~tate-Aid project. '
tn,,,, i(.'~~ I
2.2 Scope
The proposed project consists of the improvements of Smith town Road from the
city limits on the west end, to the west side of Country Club Road. Two
rehabilitation options were studied. Option #1 includes overlaying the existing
roadway. Option #2 includes the reclamation and re-paving of the existing
roadway. Additionally, the report investigates adding six-foot (6') wide gravel
shoulders on one or both sides of the existing roadway. The gravel shoulders
can be added to either ofthe street rehabilitation options.
None of the proposed improvement options will alter the existing road profile.
Because of the designation as Municipal State Aid Roadway, Smithtown Road
must be constructed according to current. State Aid Standards. The city may be
required to ask for variances to the standards based on the fact that the
improvements will not change the profile.
2.3 Data Available
In preparing this report, all or portions of the following sources of information
were utilized:
(1) City of Shore wood Topographic Maps
(2) City of Shorewood Parcel Maps
(3) Color Aerial Photography as supplied by Hennepin County
No field survey work was authorized or utilized.

3 General Backf!round
3.1 Project History
Smithtown Road is an existing Municipal State Aid street that runs from the
southern city limit line between Lake Minnetonka and Lake Virginia, north and
east across the City of Shorewood. It is the main east-west corridor across the
western end ofthe city. Several years ago a water main system was constructed
in Smithtown Road. Several trenches for the main and service laterals have
settled creating an uneven travel surface. The roadway profile, for the most part,
follows existing terrain. .
3.2 Existing Conditions
3.2.1 Streets
Smithtown Road is an older roadway of varying paved widths. It varies from
approximately 22 feet wide to about 28 feet wide, with a median width of about
25 feet. There is no concrete curb and gutter. The preliminary roadway
geometry and profile, as prepared from the available topography plans, has one
horizontal curve and several vertical curves that do not meet the Mn/DOT State-
Aid Standards, and will require variances or exceptions. The general condition
ofthe roadway is fair to poor. The existing right-of-way width varies
considerably over the length of the project area. There are several areas along
the north side of the roadway with no recorded public right-of-way.
3.2.2 Sanitary Sewer, Watermain
The existing watermain in and along Smithtown Road is approximately 5 Yz
years old and should be in very good condition. The existing sanitary sewer is
in unknown condition. It is highly recommended that a televised inspection of
the sanitary sewer mains be done prior to when the proposed roadway
improvements are constructed so any needed repairs can be coordinated with the
road work.
3.2.3 Storm Sewer
Drainage along Smithtown Road is almost entirely handled by roadside ditches.
There are a few existing cross culverts.

3.2.4 Private Utilities
Private underground utilities consisting of telephone, gas, electric and cable TV
are located in and along different stretches of Smithtown Road. It is anticipated
that only minimal adjustments, if any, will be required to the existing private
utilities.

4 Proposed Improvements
4.1 Streets
This feasibility report investigates two different options for the proposed
improvement of Smithtown Road. Further, Smithtown Road was divided into
two segments for estimated cost purposes. Segment #1 runs from the city limits
to the west side of Eureka Way and includes about 9,020 linear feet of roadway.
Segment #2 starts at the west side of Eureka Way and runs to the west side of
Country Club Road, just north of City Hall. Segment #2 includes about 4,572
linear feet.
Both options will follow the existing horizontal and vertical alignments with
some minor alignment and/or grade changes to bring more of the roadway up to
the minimum State Aid Standards. A full field survey would be required prior
to final design to determine exactly where the existing roadway does not meet
the minimum requirements and where, ifpossible, grade or alignment changes
could be made to allow more ofthe improved roadway to meet the 30 MPH
minimum design speed requirements.
Both options utilized a rural section (i.e. no curb and gutter) to match the
existing roadway design.
General assumptions used in the Opinion of Probable Cost for both options
include:
a) Minimum or no changes in alignment or grades.
b) Transitions into driveways and at intersections with existing roadways
would be minimal and incidental to the construction cost. No driveway
reconstruction or overlay was provided for.
c) Option #2 (reclamation) does include saw cutting across each existing
. roadway at intersections to allow for a betterpavement joint and a smoother
transition.
Option #1
Option #1 includes the placement of a bituminous leveling course to provide an
even base and to rebuild the crown where required. For estimating purposes, a
1" leveling course was assumed. A two-inch (2") thick bituminous wearing
course is anticipated.

WSB Project No. 1074-58
Page 5
t
4.2
Option #2:
Option #2 would involve a bituminous pavement reclamation process, which
consists of pulverizing and mixing of the existing bituminous pavement
structure with the existing aggregate base, so as to produce a homogenous dense
graded aggregate base. TIns process results in a longer service life of the
rehabilitation over an overlay process. Additional aggregate base-class 5 (100%
crushed rock) would be added as needed to create a minimum of six-inches (6")
of base and to shape the roadway crown. Bituminous pavement would be placed
in two 2"courses to create a 7-ton roadway. If the project is ordered, soil
borings should be performed to determine the soil bearing strength and the depth
of the existing aggregate base. The proposed road section would then be revised
if necessary.
VarianceslExceptions:
Typical horizontal and vertical curve design for a proposed State-Aid street must
meet the requirements for a 30 :MPH design speed. The horizontal curve near
the West end and near the intersections with Boulder Bridge Circle and Boulder
Bridge Drive currently does not meet this requirement. There are also several
places along the existing roadway where the vertical curve grades do not meet
the State-Aid design. lfthis project is authorized for design, a field survey
would be performed to determine how many variances would be required. If
option #2 (reclamation) is accepted, the design stage would include modifying
the grades with the addition of aggregate base, to minimize the number of
variances needed. In either option, the city would present the argument that the
intention of the proposed road improvements are to provide the best road
possible with the minimum of disturbance. The proposed project is not a road
reconstruction proj ect, in which case, the stretches of roadway that do not meet
the State-Aid standards may be exempted from State Aid design criteria, yet still
eligible for State Aid financing.
Shoulders
This report includes the potential to add six-foot (6') wide gravel shoulders to
one or both sides of the road. The shoulders can be added to either Option #1 or
Option #2 as the city desires. The shoulders could also be utilized by
pedestrians or bicyclists.

4.3 Miscellaneous
a) Street Signs
It is possible that some street signs may need to be salvaged. relocated or
replaced as part of this proj ect. It is assumed that city maintenance crews
would do this, so no costs were included.
b) Utility Poles
If shoulders are added to the road. it is possible that some utility poles may
need to be relocated. These relocation costs would be born by the utility
companIes.
c ) Wetlands
There may be some existing wetlands adjacent to the roadway. It is
assumed by this report that no wetlands would be impacted by this project.
This should be verified as part of the design process.
d) Existing Ditches
Since this project is generally a maintenance project, the cost estimate does
not include any costs for any extensive ditch work or corrective action for
drainage issues. The addition of the shoulders would result in some grading
along the yards and sod restoration.
4.4 Permits
It is anticipated that no permits would be required for either the overlay option
or the reclamation option. The construction of gravel shoulders may require
permits from one or more of the following agencies:
. Minnesota Pollution Control Agency (MPCA).. .NPDES
. Minnesota Creek Watershed District (MCWD).. .Erosion Control
Permit

5.1 Opinion of Probable Cost
A detailed opinion of probable cost is included in Appendix B of this report.
The opinion of probable costs includes a 10% contingency and 30% indirect
costs. The indirect costs include legal, engineering, and administrative costs
associated with the project. The project costs are summarized as follows:
Option #1 Option #2
Bituminous Pavement Reclamation & Bituminous
A. Streets Overlay Option Pavement
Segment #1 (west end) $227,200 $376,800
Segment #2 (east end) $ 114,600 $179,000
Total Roadway $341,800 $555,800
B. Shoulders One side Two sides
Segment #1 (west end) $55,000 $ 110,000
Segment #2 (east end) $ 25,000 $ 50,000
Total Roadway $80,000 $160,000
5.2 Funding
It is anticipated that 100% of the funding on this project will be provided
through Municipal State Aid (MSA) funds. The city could elect to use their
local road fund, but the MSA fund has a greater balance and the local road fund
should be saved for non-State Aid roads.
5.3 Rigltt-of-Way
WSB had previously completed a right-of-way survey and map for Smithtown
Road. This analysis indicated that only 76 out of a total of 136 parcels has
Feasibility Report
City of Shorewood, MN
Smithtown Road Improvements
City Project No.
WSB Project No. 1074-58
Page 9
provided a legal right-of-way for the road. The remaining parcels do not show
any legal right-of-way, but rather there is probably a "prescriptive" easement
over those parcels. By virtue of maintaining the road, the city has obtained a
prescriptive easement over the portion maintained. Even with that~, the
city should consider securing all remaining legal right-of-way to a minimum
width of 66-feet to ensure all future improvements of Smithtown Road cannot be
questioned.
WSB has prepared a parcel map showing all right...of-way needs. The city
attorney and staff should commence the process to obtain all remaining right-of-
way prior to this project proceeding.

6 Preliminary Schedule
The right-of-way acquisition is essential for this project to get completed. This item has
the potential to delay the construction of the project until 2002. The council could elect
to utilize all of2001 for the right-of-way acquisition with construction occurring in
2002. One or both segments could be done entirely in 2001, depending on the right-of-
way acquisition process.

7 Feasibility and Recommendation
The Smithtown Road Improvements Feasibility Report presents two options.
Option #1 consists of placement of a bituminous leveling course and a bituminous wear
course over the existing roadway. Option #2 consists of reclamation of the existing
pavement and placement of four-inches of bituminous pavement to build a 7 -ton rural
roadway. Both options could include the construction of six-foot wide gravel shoulders
on one or both sides of the improved roadway.
The total estimated cost of Option #1 is $341,800. The total estimated cost for Option
#2 is $555,800. For shoulders on one side of Smithtown Road the total estimated cost is
$80,000. Shoulder on two sides would be approximately double the cost of one side -
$160,000. If shoulders impact wetlands, additional costs may be incurred. The current
total balance in the City's Municipal State Aid Account is $ . This balance
is available to complete this project.
The most cost-effective option from an engineering prospective would be option #2,
reclamation of the existing bituminous paving. This option would result in a quality
roadway with an expected design life of 12-15 years. Option #1, Overlaying the
existing paving would have a design expectancy o~ears.
J.-lfJ ,,~,.,
Construction of the gravel shoulders is feasible from an engineering perspective. If
sufficient funds are available, gravel shoulders should be constructed on both sides of
Smithtown Road.
WSB & Associates recommends option #2, the reclamation option. This project is
necessary, feasible and cost effective.
