BACKGROUNDMUSTIFICATION:
As per City Council direction, we have prepared a Feasibility Report for the Jagler Avenue and 100'h
Street Improvement Project. A majority of the current property owners petitioned the City requesting
the streets be improved from a gravel surface to a bituminous surface. The Project is located along
Jalger Avenue and 100th Street north of 95th Street (C AH 39). It includes shaping and paving Jagler
Avenue and 10011 Street. Two cul-de-sacs are proposed on 100th Street with 40 foot radii to allow traffic
to turn around and provide access to the adjacent properties. With the construction of the cul-de-sac
on the east end of 100th Street,, City staff is proposing to vacate a portion of the existing right-of-way to
the adjacent property owners.

PROPOSED STREET RECONSTRUCTION
JAL ER AVENUE— 95TH STREET TO Io TH STREET
CITY OF OTSEGO, MN
I. INTRODUCTION
The purpose of this Feasibility Report is to present the City of Otsego with a
preliminary examination of municipal street improvements for Jalger Avenue and 1000 h
Street in Otsego, Minnesota (see Exhibit A — Project Location Map). The report
discusses the proposed scope of improvements, preliminary cost estimates, potential
assessment costs, and a project schedule. The report has been prepared in
compliance with Minnesota State Statutes 429 for projects resulting in special
assessments.
[11. PROPOSED IMPROVEMENTS
A. Project Location
Jalger Avenue and 1 00th Street are located in Section 10 and 15, Township 121,
Range 24, City of Otsego, Wright County, Minnesota. Jalger Avenue, from 95 th
Street (CSAH 39) to 1 00th Street and I OOt" Street, from the west cul-de-sac to the
east cul-de-sac provide direct access for nine properties to 95 th Street (CSAH
39). Eight of the parcels are within the City of Otsego and one parcel is with
Monticello Township. All parcels are rural residential type lots. The project area
and roadway location is depicted on Exhibit A.
B. Existing Conditions
Jalger Avenue and 1 00th Street utilize a rural road section gravel surface. Jalger
Avenue is approximately 1,495 feet in length. The width of the existing gravel
typically varies from 22 to 24 feet, though it widens to almost 40 feet at the
intersection with Io t" Street. 1000, Street is approximately 290 feet in length with
an elongated cul-de-sac at the West end and a semi -circle intersection providing
access to three properties at the east end. The width of the existing gravel is
approximately 29 feet, with the west cul-de-sac being 64 feet x 95 feet.
A geotechnical investigation has not been performed at the time of this report.
The existing road section was hand dug to check the existing depth of gravel.
Existing Class 5 thicknesses ranging from 4.5" to 6" were found. The Wright
County Soil Survey issued by the USDA Soil Conservation Services depicts a
subgrade of a loamy sand mix with a small area of loamy soils near 95th Street
(CSAH 39). Possible areas of concern (i.e. soft spots, potholes, continually
failing areas) were discussed with City personnel and no problems were
identified. Therefore, for this report, the subgrade was assumed to be adequate.
2
Drainage is conveyed by the existing ditches, which are generally shallow and
typically have in -slopes less than 4:1. The drainage is split at approximately the
midway point along Jalger Avenue. The north half of Jalger Avenue flows
through the ditches and then continues via sheet flow to the north, towards the
Mississippi River. The south half of Jalger Avenue flows through the ditches to a
creek that flows to the Mississippi River.
C. Proposed Improvements
The proposed street improvement project consists of shaping and paving the
existing gravel surfaces. The project would require adding gravel to widen the
road to a consistent width and obtain sufficient thickness to extablish a typical
section that is in general conformance with City Street Standards. No easements
or right-of-way are proposed to be acquired. It may be necessary to vacate a
portion of right-of-way along 1 00th Street and turn it back to the resident(s). See
section V. Right-of-Way/Easements for more information.
We recommend all road sections be a paved rural section with no curb and
gutter. The existing gravel surfaces will be graded to achieve a minimum 24 foot
wide surface with a 1/3 inch per foot (2.78%) crown. After the existing gravel is
graded, 2 inches of additional virgin Class 5 aggregate (100% crushed) shall be
placed to achieve a minimum of 6 inches of aggregate base. A test roll would be
performed to verify the compaction of the existing sub base. Any soft spots
would be excavated and replaced with suitable soils. Finally, a 22 foot wide, 2.0
inches bituminous non -wear course will be placed followed by a 1.5 inches
bituminous wear course. The existing road profile would remain the same but
raised approximately 5 inches. All driveways will be adjusted accordingly. The
existing cul-de-sac at the west end of 1 00th Street will be regraded to a 40 foot
radius cul-de-sac and relocated within the existing right-of-way. The east leg of
the I 001h Street intersection will be revised to a 40 foot radius, semi -cul-de-sac.
We further recommend that topsoil shouldering material, approximately I foot
wide, be placed on each side of the road to reestablish the shoulder level with
the new bituminous surface. The proposed typical road section is shown in
Exhibit B and the proposed realignment of 1 00th Street is shown in Exhibit C.
Bituminous surfacing reduces or eliminates issues associated with gravel streets
such as frost boils in the spring, wash boarding, rutting, dust, and gravel into
yards. The value of existing housing is positively benefited by fronting on and
being accessed by bituminous paved streets.
Surface water within the project area will be conveyed via the existing ditches
driveway culverts. No proposed ditch grading is anticipated.
0
III, INITIATION
Residents of the Billstrow's Riverview Addition subdivision have signed a petition
requesting the City complete a feasibility report regarding paving the existing gravel
streets of Jalger Avenue and `10 1h Street. The City Council accepted the petition in
accordance with the City Code and authorized a feasibility report be completed to
determine costs and potential funding sources.
IV. FEASIBILITY
From an engineering standpoint, the project is feasible, and will benefit the
property being served. It can be accomplished as proposed, and need not be
constructed in conjunction with any other project. The City and the persons assessed
should review the project for benefit to determine the economic feasibility of the
proposed improvements.
V. RIGHT-OF-WAY.1 EASEMENTS
The existing streets and proposed street upgrades are located within the existing
platted 66 foot wide right-of-way. No additional utility and drainage easements are
anticipated at this time. If additional utility and drainage easements are required based
on the final design, these permanent and temporary easements will need to be provided
to the City of Otsego.
Three properties access 100th Street to the east of Jalger Avenue. The existing road
alignment in this area does not match the platted right-of-way. There are fences,
driveways, and a septic system that encroach within the existing right-of-way and
easements. We recommend that sufficient right-of-way and easement remain to
provide access to all lots and to cover all City maintained streets as well as provide
enough area for small utilities to be maintained. The remaining right-of-way and
easements could be vacated at this time and turned back to the adjacent property
owners to maintain. Vacation of the right-of-way may also require approval of a
conditional use permit to allow less than the minimum frontage to a public street as
required by the Zoning Ordinance. The proposed realignment of 100th Street is shown
in Exhibit C.
V1. PERMITS
A Wright County right-of-way permit will be required to work at the intersection of
Jalger Avenue and 9 Street (CSAH 39). At this time, no other permits are required
for this project.
VII. COMPLETION
This project is proposed to be completed during the 2013 construction season.

IX. ESTIMATED PROJECT COST
A detailed estimate of 2013 construction costs for the improvements has been
prepared. The costs and quantities herein are estimates only and are not guaranteed.
The estimated costs shown are determined through experience with other projects of
similar scope that have been built in the past. The estimated cost includes a
contingency factor to cover items and issues that are unforeseen at this time. Final
5
contracts will be awarded on a unit price basis. The total estimated project cost is
$128,331.00. An estimate of the cost of the improvements is shown in Exhibit D.
X. PROPOSED FUNDING
All of the costs for the improvements of Jalger Avenue and 1001h Street are
proposed to be assessed to the benefiting properties. For this project, the
recommended assessment method is to assess the benefiting properties on a per unit
basis. The proposed nine parcels (9.0 assessment units) shown in Exhibits E and F,
will benefit from these improvements. The property at the northwest corner of 95th
Street (CSAH 39) and Jalger Avenue has direct access to 95th Street (CSAH 39) and
cannot be subdivided therefore it does not benefit from the project and will not be
assessed. Theproperty at the northeast corner of 95 th Street (CSAR 39) and Jalger
Avenue, Parcel #9, currently has direct access to CSAH 39 but is subdividable. Any
future subdivision of this parcel will require access to Jalger Avenue and is therefore a
benefiting property.
The City may pass a general obligation/revenue bond that will be backed by
assessment of the costs to the benefiting properties of fund internally. The
assessments may be paid in full up front or amortized over a period of time, typically 10
years, with an interest rate as determined by the City Council. The City Code required
that the interest rate be established at 1.5% above the bond rate or the rate if bonds
were to be issued.
The estimated total improvennent cost is $128,331.00. One hundred percent (100%) of
the improvement costs are to be assessed to the benefiting properties.
Access to the property at 9000 1 00th Street, Monticello, MN 55362 is provided via 1 00th
Street and Jalger Avenue. This parcel is within Monticello Township. In order for the
City of Otsego to assess the property for their portion of the project costs the City of
Otsego and Monticello Township must enter into an agreement in which Monticello
T
Township will assess the parcel and reimburse the City of Otsego prior to the City
awarding a contract to undertake the project.
X1. ESTIMATED ASSESSMENT
The assessment portion of the project would be 100% of the total project costs
depending on the final typical section. By dividing the total amount to be assessed to
the benefiting properties by the number of assessable units (9.0), an assessment value
is obtained. The estimated cost per unit was determined to be $14,259.00 (Exhibit F,
Benefiting Property Assessment Summary). The per unit method of assessment was
used due to all the benefiting properties being large single family lots and use the
streets in much the same manner for access.

X11. CONCLUSION AND RECOMMENDATION
This report analyzed the feasibility of reconstructing Jalger Avenue, from 95 th
Street (CSAH 39) to 1 00th Street and 1 00th Street, from the west cul-de-sac to the east
cul-de-sac. The total estimated project cost for this improvement is $128,331.00. One
hundred (100%) of the costs are to be assessed to the benefiting property owners. The
proposed improvements are necessary, cost effective and feasible from a technical and
engineering standpoint, and benefits the properties shown on Exhibit E and the list of
owners shown on Exhibit F.
This report will be forwarded to the property owners proposed to be assessed for this
project for their consideration and comment. We recommend that the City Council
accept this report and order a Public Hearing.
