VILLAGE EAST SANITARY SEWER IMPROVEMENTS: TRUNK
HIGHWAY 5 TO UNION PACIFIC RAILROAD
CITY OF LAKE ELMO
Project No: 2014.127
PROPOSED IMPROVEMENTS AND RECOMMENDATIONS
This document officially amends the Village East Trunk Sanitary Sewer Extension Feasibility Report dated
June 2014 that was adopted by the Lake Elmo City Council on June 17, 2014. On July 14, 2014,
contractor bids were received for the improvements with the low bid amount exceeding the estimated
construction cost presented in the report. The purpose of this amendment is to revise the preliminary
assessment roll to reflect the increased project costs accordingly. The revised assessment roll has been
provided to the benefitting property owners by mail and at a stakeholder meeting held by the City.
Acceptance of this report will provide the City the option to assess the improvements to the benefitting
property owners at the higher cost reflected in contractor bids.
At the request of several property owners in the Village area, the City of Lake Elmo, property owners
and developers are working collaboratively to complete the extension of trunk sanitary sewer from the
new lift station in Reid Park to the intersection of 39th Street North and Trunk Highway 5, then along
39th Street North to CSAH 17 (Lake Elmo Avenue) with the sanitary sewer stubbed to the west side of
the County Road.
To pursue this improvement, the project was split into two separate improvement projects, one to be
completed as a public improvement project led by the City (the 39th Street: Street and Sanitary Sewer
Improvements) and the other to be constructed privately by developers (the Village East Trunk Sanitary
Sewer Improvements). In both cases the City would cover pipe oversize charges funded through the City
Sewer Enterprise Fund. The City initiated the 39th Street: Street and Sanitary Sewer Improvements by
authorizing the feasibility report on March 18, 2014. A public improvement hearing was then held on
May 6, 2014 and the council ordered the preparation of plans and specifications.
Subsequent to the direction to proceed with the 39th Street: Street and Sanitary Sewer Improvements,
two of the property owners, representing three parcels, requested to have a portion of the Village East
Trunk Sanitary Sewer Improvements, that portion from Trunk Highway 5 to the south side of the Union
City of Lake Elmo, MN. Project No: 2014.127
Village East Trunk Sanitary Sewer Improvements PAGE 3
Pacific Railroad tracks, to be publicly bid and constructed as a part of the 39th Street North: Street and
Sanitary Sewer Improvements with the costs to be assessed to the benefiting properties.
To accommodate this request, this feasibility report was prepared to satisfy the legal requirements of
Minnesota State Statute 429. The report identifies the necessary improvements, the estimated project
costs, the assessment methodology and preliminary assessment amounts to be levied against properties
adjacent to and benefitting from the proposed improvements. The recommended assessment
methodology is consistent with the City of Lake Elmo Special Assessment Policies and Procedures for
Public Improvements, amended December 17, 2013.
The proposed improvement includes the extension of approximately 2,000 feet of 15‐inch diameter
trunk sanitary sewer line between the existing Union Pacific railroad tracks and Trunk Highway 5. Three
(3) developable properties have been identified that will benefit from these improvements by providing
them the opportunity to connect to the municipal sewer system.
The project is necessary, cost‐effective, and feasible and will result in a benefit to the properties
proposed to be assessed. It is recommended that the City Council accept this Report, hold the public
hearing, and order the improvements.
RIGHT‐OF‐WAY AND EASEMENTS
To implement the proposed improvements permanent roadway and utility easements must be acquired
from the adjacent property owners. Temporary construction easements are also needed for the
duration of the construction activities and through the project’s warranty period. This report assumes
that the necessary easements will be dedicated to the City at no cost.
PERMITS AND APPROVALS
The following permits will be required to implement the proposed improvements. The UP Railroad
utility crossing is a permit that must be acquired due to the added scope of work being requested:
Union Pacific Railroad Utility Crossing Permit.
Minnesota NPDES‐SDS Construction Stormwater General Permit.
Valley Branch Watershed District Permit for Erosion Control.
Minnesota Department of Transportation Right‐of‐Way Permit.
Minnesota Pollution Control Agency (MPCA) Permit for sanitary sewer extension.
City of Lake Elmo, MN. Project No: 2014.127

SUMMARY OF ESTIMATED PROJECT COSTS
The total amended estimated project costs for the Trunk Sanitary Sewer Extension Improvements is
$412,600. The total project cost is based on contractor bids received and by incorporating engineering,
geotechnical investigations, and contingences. Detailed estimates are attached to this report for
reference. No allowance has been provided for easement and right‐of‐way. A 2.5% allowance is included
for legal, fiscal and administration costs.
FINANCING OF IMPROVEMENTS
This project will be partially financed by levying special assessments against the benefiting properties.
Special assessments are levied in accordance with Minnesota Statutes Chapter 429 and the City of Lake
Elmo Special Assessment Policies and Procedures for Public Improvements, amended December 17,
2013. Assessments will be proportioned based upon the projected sewage generation of each property
within the trunk sewer service area in relation to the total contributing sewer service capacity. To
facilitate this allocation, each property is assigned a Residential Equivalent (REC) unit basis. The total
cost for the overall extension of sanitary sewer from the lift station through 39th Street North was
divided by the total number of RECs connecting to the sewer main. Each benefitting property’s
assessment was then determined based on how many RECs it contains.
A preliminary assessment roll has been prepared for the sanitary sewer improvements and is attached
to this report. There are three properties comprising of 326 RECs that directly benefit from the proposed
improvements, however there are an additional 833 RECs sharing in the total project costs for the
combined trunk sewer extension, but paying their proportionate cost directly or assessed as a part of
the 39th Street North Improvement project.
The City may use fund reserves or bonds for the improvements to pay the up‐front project costs and to
cover City cost participation. Special assessments would be levied against the benefiting properties with
payment terms structured so that the City receives funds to meet debt obligations. Consistent with the
City’s adopted Special Assessment Policy, it is recommended that the sanitary sewer improvements be
levied over a 15‐year period. Assessments would be assigned an interest rate of 2% over the bond rate
for the project. This will address the internal costs the City will incur associated with the bonding,
documentation of the assessments, and dealing with delinquent assessment payments.
