RE: 175th AVENUE FEASIBILITY STUDY
Dear Council Members:
Attached please find a copy of the 175th Avenue feasibility study. This feasibility study
discusses the installation of lateral sanitary sewer and trunk water main together with the
reconstruction of the 175th Avenue from Tyler Street to Fillmore Street. As the City
Council is aware the sanitary sewer is to be funded by the developers of Park Pointe
Addition, and the water main is going to be bid as an alternate with funding possibly
provided by the City and the Elk River Municipal Utilities. If no funding can be provided
for the water main it can be deleted from the project.
Therefore the only improvement the feasibility study discusses assessing to the abutting
properties is the reconstruction of the street. The recommendation of the feasibility
study is to assess each residential unit $5000.00. This is the same amount that is
proposed in the City Pavement Management Plan for street assessment to properties
involved in reconstruction of streets in the old core City. With the large Mitchell property,
a recommendation to assess blank units is made in the feasibility study based on the
average size of residential property versus the frontage contained in the Mitchell piece.
The same is true of the Klein property.
As the City Council is aware, we have acquired additional street, drainage, and utility
easements from all of the properties abutting 175th Avenue. During the easement
acquisition phase I met with each property owner personally. In our many discussions, I
have initially indicated that the City Council consensus was that if the easements were
all granted for no compensation the City would consider no street assessment. As the
table on page 5 of the feasibility study indicates, I was unsuccessful in getting all of the
easements signed for no compensation. There were six property owners that requested
compensation, totaling slightly less than $20,000.00. There were a total of 10 property
owners that did give their easement for no compensation.
As the City Council considers this feasibility study, there are really three options you
could pursue. They are as follows:
City Council could decide that there will be no street assessment on 175th
Avenue, and the assessment process could end at this point.

City Council could decide to proceed to a public hearing with the
recommendation of a $5000.00 assessment to each residential unit.
City Council could direct staff to amend the feasibility with a modified proposed
assessment rate and proceed to a public hearing.
If the Council wants to pursue either of the last two options, it would be appropriate
to consider adoption of the attached resolution, which approves the feasibility study
and orders a public hearing. If the Council wants to go to a public hearing with a
modified assessment rate, City staff would simply prepare an amendment to the
feasibility study, which the Council could consider at a future meeting prior to the
public hearing.
I will be in attendance at your May 13, 2002 City Council Meeting to discuss this
issue further.

Feasibility Study 175th Avenue Improvements
City of Elk River
INTRODUCTION
On January 28, 2002, the Elk River City Council adopted Resolution 02-08 authorizing
Howard R. Green Company to prepare a Feasibility Study for the 175th Avenue
Improvements Project in the City of Elk River. The project location is shown on Exhibit
1. The proposed 175th Avenue Improvements includes the reconstruction of the road,
installation of lateral sanitary sewer, trunk watermain, and a detached bituminous trail.
II. PROJECT SCOPE
The purpose of this study is to analyze the extension of lateral sanitary sewer and trunk
watermain together with the reconstruction of 175th Avenue from Tyler Street to
Fillmore Street, and determine the feasibility of the proposed project. This study will
discuss the existing conditions, proposed improvements, and estimated construction
costs with the addition of overhead costs to include city administration, engineering,
fiscal, land acquisition and legal expenses. The City's Assessment Manual and past
practices will be used as guidelines to discuss financing methods for the proposed
improvements.
III. NECESSITY AND COST-EFFECTIVENESS
The improvements proposed in this study are necessary for a number of reasons. 175th
Avenue is in extremely poor condition and normal maintenance and repair operations
are no longer sufficient. The construction of lateral sanitary sewer and trunk watermain
will allow proposed new developments to be serviced. The trunk watermain will also
provide the first segment of a loop to continue to improve fire flow conditions in the
southern portion of the East Elk River Area. Installation of lateral sanitary sewer and
trunk watermain is necessary to provide the "backbone" of infrastructure for planned
future development in the East Elk River Area. The street reconstruction is necessary
to provide an adequate transportation system in this area of the city.
The proposed improvements will be developed into a project large enough to ensure a
competitive bidding process. Therefore, the proposed improvements will be cost-
effective. Based on the information contained within this report, the proposed
Howard R. Green Company
Project No. 806550J
Feasibility Study 175th Avenue Improvements
City of Elk River
improvements are necessary, cost-effective, and feasible from an engineering
standpoint.
IV. EXISTING CONDITIONS
Street
175th Avenue starts at Tyler Street and continues 1-mile east to Fillmore Street. The
westernmost 300-feet of the road was reconstructed as part of the East Elk River Area
Tyler Street Improvements project in 2000. The existing section of 175th Avenue
consists of a two-lane, 21-foot wide bituminous surface with no shoulders. The newly
constructed segment to the west is 40 feet wide with curb and gutter and storm sewer.
The existing pavement is severely distressed with extreme cracking and rutting. There
is a defined ditch area and although the road is currently raised above the adjacent
land, there is not a clear flow pattern for water runoff.
The property within the study area is zoned Single Family Residential (Rla and Rle)
and Agricultural Residential (AR).
SanitarF Sewer
During construction of the East Elk River Area Phase I project, an 8-inch sanitary sewer
line was stubbed out from Tyler Street into 175th Avenue for future connection.
Existing residences along 175th Avenue currently have septic systems to handle
sanitary waste. There is a significant amount of undeveloped land on the north side of
175th Avenue at the easterly end.
Watermain
A 16-inch trunk watermain was also stubbed into 175th Avenue from Tyler Street as
part of East Elk River Area Phase I project.
A new 1.5 million gallon water tower is under construction north of the proposed Park
Pointe development in the Eagles Marsh development.

City of Elk River
Storm Drainaqe
There is no existing storm sewer located within the project area. Runoff from storm
events is collected and conveyed through ditches along the existing roads. Culverts are
located where appropriate when roads and driveways cross these ditches. There is an
existing culvert under 175th Avenue that drains water from Kliever's Marsh to the ditch
system south of 175th Avenue.
Existinq Private Utilities
Private utilities which have facilities in or near the project area will be notified of the
project and requested to incorporate repairs and replacements with the project as
needed at their cost. Private utilities include Qwest, Connexus Energy, Northstar
Access, Charter Cable TV, and Minnegasco.
V. PROPOSED IMPROVEMENTS
The proposed improvements for the 175th Avenue project include lateral sanitary
sewer, trunk watermain, street construction, and a detached bituminous trail. A detailed
description of each proposed improvement is provided below.
Street
The proposed street improvement consists of reconstruction of 175th Avenue from the
segment constructed as part of the East Elk River Area Tyler Street Improvements
project east to Fillmore Street. A connection will be made to existing Polk Street and a
new entrance constructed to future Ivanhoe Street accessing Park Pointe Addition. The
proposed street section for these roads is in accordance with Mn/DOT requirements for
an MSA eligible road, as 175th Avenue is part of the City's MSA system. Based on soil
borings, the proposed pavement section consists of 6 inches of Class 5 aggregate
base, 2 inches of bituminous base course, and 1-½ inches of bituminous wear course.
The proposed road section will consist of two 12-foot lanes with 6-foot bituminous
shoulders. Twelve-foot turn and bypass lanes will be constructed at Ivanhoe Street.
Proposed improvements also include a 10-foot bituminous detached trail located on the
north side of 175th Avenue.
The proposed street section is shown on Exhibit 2.

City of Elk River
SanitarF Sewer
The proposed sanitary sewer improvement, as shown on Exhibit 3, consists of
extending an 8-inch sanitary sewer main east along 175th Avenue to the western edge
of Park Pointe Addition. This sanitary sewer line will be constructed at minimum grade
to try to maximize the area of service.
Sanitary sewer stubs and services will be placed to the north and south along 175th
Avenue to allow for future connections of the residences that abut 175th Avenue, or
future development to the south.
Waterrnain
The proposed watermain improvement, as shown on Exhibit 3, includes the installation
of a 16-inch trunk watermain east along 175th Avenue to the western edge of Park
Pointe.
Watermain stubs and services will be placed to the north and south along 175th Avenue
to allow for future connections of the existing residences or future development to the
south.
Modeling of the proposed water improvements was completed using Cybernet software
to verify proposed sizing of the watermain. The two criteria used when modeling the
system were a fire flow of 3,500 gallons per minute (gpm) and residual pressure of 20
pounds per square inch (psi). The Insurance Services Office (ISO) requires that fire
flows for industrial and commercial areas meet or exceed 3,500 gpm with a residual
pressure of 20 psi or greater in the system. Modeling of the system with the proposed
trunk watermain sizing produced results that satisfied the above criteria.
Storm Drainage
Ditches will be constructed adjacent to the roadway to convey stormwater flow. Water
will be directed to proposed ponds within the Park Pointe Development or to a former
County Ditch system that conveys water to the south and west, ultimately flowing into
the Mississippi River.
Culverts will be placed under driveways and connecting roads where necessary.

VI. RIGHT-OF-WAY, EASEMENTS AND PERMITS
Right-of-Way and Easements
Existing right-of-way width is generally 33' on either side of the road centerline. An
exception is along the Shores of Briarwood plat, along the north side of 175th Avenue
near Polk Street, where it is 40' in width. Proposed permanent right-of-way widths are
50' to the north and 45' to the south. Permanent street, utility and drainage easements
will be acquired from 17 parcels. Temporary construction easements will be required
from 13 of the parcels to accommodate construction activities.
On March 18, 2002 the City Council adopted resolution 02-24 authorizing eminent
domain for the acquisition of easements along 175th Avenue. Initial offers were made
to most property owners. Through a series of meetings and negotiations all easements
have been acquired. Table 1 below lists the 17 property owners, initial offer made for
the easement and the final settlement amount.

VIII. FINANCING
In January 1999 the City of Elk River submitted the 175th Avenue improvements project
for TEA-21 Federal funding. The project was ranked by the Area Transportation
Partnership (ATP) and approved by Mn/DOT and the Federal Highway Administration
later that year. Federal Surface Transportation Program (STP) funds are available to
cover $360,000 of the road construction, to a maximum of 80% of the road construction
portion of the project. Right-of-way, design and administration costs are not eligible for
Federal fund reimbursement.
As part of the approval process for the Park Pointe Addition, a condition was placed on
the development that the developers pay for the lateral sanitary sewer from Tyler Street
to the west edge of the development.
The City Council and Elk River Municipal Utilities Commission discussed the funding of
the trunk watermain. The City's comprehensive plan indicates adjacent land to the
north would not be assessed before 2007 for utilities and the property to the south is not
in the urban service area. Therefore, it was a joint decision to bid the watermain as an
alternative which could be deleted from the project. If watermain is included in the
construction, the past policy indicates that the Elk River Municipal Utilities would fund
7
Howard R. Green Company
Project No. 806550J
Feasibility Study 175th Avenue Improvements
City of Elk River
the lateral portion with the City funding the trunk oversizing until adjacent properties
were assessed.
It is proposed to assess the street construction at a rate of $5,000 per residential unit.
There are a total of 25 residential units along 175th Avenue. The only properties with
more than one unit is the Klein parcel with two and the Mitchell parcel with 11. The
Cargill parcel has not been proposed to be assessed because of the global agreement
between the City and Cargill. The proposed assessable units are shown on Exhibit 4.
IX. PROJECT SCHEDULE
The schedule for the 175th Avenue Improvement project, as provided in Table 3, is
based upon 9uidelines established in Minnesota State Statues, Chapter 429, Local
Improvements and Special Assessments. These dates will be revised if necessary as
the project develops.

X. CONCLUSION
The total estimated project cost, including overhead costs is $941,600. The project is
necessary and cost-effective. As previously stated, this cost will be financed through a
combination of assessments to benefiting properties and TEA-21 funds, Municipal State
Aid funds, Elk River Municipal Utilities funds, and City funds.
