TABLE OF CONTENTS (continued)
1. EXECUTIVE SUMMARY
City Project No. 387 consists of reconstructing Old County Road 38 (135 Street West) from the
easterly tract line of the Harmony residential subdivision east to Akron Avenue. The proposed
improvements consist of removal of the existing gravel surface and installing bituminous
pavement, new concrete curb and gutter, a railroad crossing, a bituminous trail, trunk sanitary
sewer, trunk water main, raw water main, storm sewer, and stormwater treatment ponds. The
proposed improvements are a continuation of the County Road 38, Phase 1 improvements (City
Project No. 393), which consisted of the upgrade of the existing rural section of Old County
Road 38 between Trunk Highway 3 and the easterly tract line of the Harmony residential
subdivision. The Phase 1 project has been delayed, and is currently proposed to be constructed
with this project.
On June 21, 2005, Dakota County turned back the ownership of County Road 38 to the City of
Rosemount. As such, Old County Road 38 will be referred to by its City name, 135 Street
West, throughout the remainder of this report.
The total estimated project cost for the 135 Street West project is $6,193,500. Of this amount,
approximately $1,340,800 would be assessed to adjacent property owners benefiting from the
proposed roadway and sanitary sewer improvements Cash payments in the amount of $330,900,
paid by Centex Homes and the Giles Properties for the Meadows of Bloomfield and Biscayne
Point North developments, respectively, have already been contributed toward the improvement
of 135 Street West. As part of the turnback agreement with the City of Rosemount, Dakota
County has contnbuted a total of $2,900,000 for the improvement of the entire length of Old
County Road 38. $660,000 has been dedicated toward Phase 1 of the project, leaving $2,240,000
available for the roadway and associated storm sewer improvements to 135 Street West. The
trunk sanitary sewer, trunk water main, and raw water main, totaling $2,056,500, would be
contnbuted by the City of Rosemount through the City's Sanitary Sewer, Water Main, and Storm
Sewer Core Funds. The remaining $225,300 would be paid out of monies set aside in the City of
Rosemount Street Capital Improvement Program (CIP).
It is proposed that construction would take place in 2006. This project is feasible, necessary, and
cost effective from an engineenng standpoint, and should be constructed as proposed herein.

2. INTRODUCTION
2.1 Authorization
On May 3, 2005, the Rosemount City Council authorized the preparation of an engineering
feasibility report for County Road 38, Phase 2 Street and Utility Improvements. Since this time,
Dakota County has turned back ownership of County Road 38 to the City of Rosemount. As
such, Old County Road 38 will be referred to by its City name, 135 Street West, throughout the
remainder of this report. This project has been designated as City Project No. 387.
2.2 Scope
This project consists of the upgrading of existing 135 Street West from the easterly tract line of
the Harmony development east approximately 7,900 feet to Akron Avenue (County Road 73).
Utility improvements will consist of trunk and lateral sanitary sewer installation, trunk water
main, raw water main, storm sewer, and stormwater ponds.
135 Street West is designated for the City's Municipal State Aid System, and as such, all
proposed improvements must be designed to State Aid standards. This improvement project is
intended to upgrade 135 Street West to accommodate traffic volumes associated with the
existing and projected development of the adjacent area.
A trunk sanitary sewer extension is proposed for construction at Bacardi Avenue, running from
135 Street West south to an existing trunk sewer stub installed as part of the Meadows of
Bloomfield project (City Project No. 351) A lateral sanitary sewer stub will be installed west of
Bacardi Avenue along 135` Street West to provide for future service extension.
A trunk water main is proposed along the entire length of the 135 Street West improvements.
The water main will connect to existing trunk water main along the length of the roadway,
including at the east end of the Harmony Addition, south of Bacardi Avenue, and at Autumn
Path, as outlined in the City's Comprehensive Water Plan.
Storm sewer improvements are proposed to collect stormwater runoff in accordance with
Municipal State Aid standards and as necessary to meet the requirements of the Rosemount
Comprehensive Stormwater Management Plan. Improvements will include storm sewer pipe and
a series of stormwater treatment ponds located along the length of the roadway.

3. GENERAL BACKGROUND
3.1 Project Location
The project includes 135 Street West from the easterly tract line of the Harmony Addition east
approximately 7,900 feet (1.5 miles) to Akron Avenue.
3.2 Project History
This project was initiated as a result of the Dakota County turnback of County Road 38, (135
Street West) to the City of Rosemount and the continuing residential developments within the
north central portion of the City of Rosemount. The area adjacent to 135 Street West has been
experiencing rapid development. The existing street section is not adequate to accommodate the
proposed traffic volumes and it is suggested that the street be upgraded to current urban roadway
standards.
3.3 Existing Conditions
135 Street West is currently a rural two -lane gravel street section with drainage ditches on each
side. The existing roadway has a width ranging between 24 feet and 30 feet, and is in very poor
condition.
There are four existing wetland areas located adjacent to 135 Street West. One of these, Mare
Pond, located east of Bacardi Avenue, will be directly impacted by the proposed improvements.
Mare Pond is considered a "Water of the State," and as such, is subject to various design
regulations previously adopted by the Minnesota Department of Natural Resources (DNR) and
the City of Rosemount. The other three wetlands, including Keegan Lake at the western end of
the project, while not directly affected by potential stormwater runoff from the proposed project,
will serve as the ultimate outlets for the new stormwater treatment ponds being proposed.
There are several existing storm sewer culverts across or along 135 Street West. The
stormwater runoff flows in ditches or directly into one of the existing four wetlands along the
road.
There are no existing sanitary sewer mains or water mains along 135 Street West. The
adjoining residential properties utilize private septic systems and pnvate wells.

4. TRAFFIC ANALYSIS
A traffic study was completed as part of the preliminary plat for the Brockway project between
Connemara Trail and 132 Street (old County Road 38), east of TH 3. The study recommended
improvement to 132 Street as part of the Phase 1 project. These improvements included
widening to provide a single lane in each direction with turn lanes at TH 3 and Brockway
Avenue. The typical section of the roadway was a 42 -foot street with curb and gutter and a
pathway on the south side of the roadway.
The Phase 2 project curves south and the street name changes from 132 Street to 135 Street
east of the Canadian Pacific Railroad. Additional study was conducted to determine if the same
typical section should be continued through Phase 2. The analysis concluded that based on the
City's transportation plan, currently being completed, by 2025 there will be approximately 5,800
to 7,300 vehicles per day on 135` Street. This is a typical volume for a three -lane roadway
section. Further analysis found that left and/or right turn lanes should be provided at only
collector streets. Minor streets into future developments will be evaluated as they are proposed.
Based on this analysis, a typical 42 -foot street with provisions for turn lanes at selected
intersections should be constructed. This is consistent with the Phase 1 street section.

5. PROPOSED IMPROVEMENTS
5.1 Surface Improvements
135 Street West is proposed for complete reconstruction as an urban section roadway with
B424 concrete curb and gutter along a revised profile. The pavement section will be designed to
accommodate the proposed increase in traffic volumes, and will consist of approximately 5
inches of bituminous pavement, 6 inches of Class 5 aggregate base, and 24 inches of select
granular borrow. The new road will be designed to meet Municipal State Aid geometric design
standards for safety, given a design speed of 40 miles per hour. As such, it is proposed that the
existing curves in the roadway east of the railroad tracks and west of Bacardi Avenue be
lengthened to meet the Municipal State Aid standards. A new railroad crossing at the existing
CP Railway railroad tracks would be installed, including railroad crossing gates. An 8 -foot
bituminous path is proposed for construction on the south side of 135 Street West from the
Harmony development to Bacardi Avenue. Bituminous path construction on the north side of
135 Street West and on the south side east of Bacardi Avenue is proposed for construction with
future development along the roadway.
The location of the proposed improvements in relation to Mare Pond posed a challenge in
determining the best option for widening of the roadway across the wetland. Soil borings taken
in the area indicated that any structure, such as a retaining wall, would need to be placed on
piling in order to support the wall and the roadway behind the wall. The same soil borings
indicated that if a retaining wall was not built, and the road was widened to fill in the wetland
areas, that the weight of the road and embankment matenal could cause future settling within the
soft wetland soils. Two options were explored for the roadway section along 135 Street in the
area of Mare Pond. The cost to install a retaining wall on each side of the road across Mare
Pond, taking into account the need to preserve and protect the existing wetland while doing so,
was estimated at $1,420,000. The cost to fill in the wetland areas, create `overburden' while
constructing the roadway (adding weight to allow compression of soft soils), purchasing
drainage easements, and constructing approximately 1.7 acres of additional wetland for
mitigation purposes, was estimated at $605,500. Based on cost savings, the option to fill in the
wetland and create new wetland elsewhere within the project was chosen over construction of
retaining walls along Mare Pond. An added benefit of choosing to perform wetland mitigation is
that portions of mitigation can be included with the required stormwater treatment ponds being
constructed along the length of 135 Street West, as well as at locations located within Meadows
Park, along the southwest side of Mare Pond, helping to reduce the cost of acquiring land for
pond construction.
The proposed street improvements can be found in Figures 2 -7 in Appendix A. A typical street
section can be found in Figure 8 in Appendix A. Cost estimates for the retaining wall and
wetland mitigation options are summanzed in the Funding section of this report, and can also be
found in Appendix B.

5.2 Sanitary Sewer
The North Central Sanitary Sewer Study (NCSSS) was developed to determine the costs to
extend sanitary sewer into the north- central portion of the City of Rosemount. The NCSSS was
also utilized to determine the best possible alignments for sanitary sewer, taking into
consideration excavation depth, property acquisition, and development patterns. According to
the NCSSS, sanitary sewer service to the area north of 135 Street West in the vicinity of
Bacardi Avenue is proposed to occur via a trunk sanitary sewer extended north from Connemara
Trail, along the west property line of Meadows Park, and then continuing north along Bacardi
Avenue. Since the area immediately south of 135 Street West in this area has already begun
development, and utility extensions for trunk water main are necessary to connect and loop the
proposed water main along 135 Street West to areas to the south, it is recommended that the
trunk sanitary sewer line south of Bacardi Avenue be extended across 135 Street West at this
time.
A 15 -inch PVC sanitary sewer trunk main is proposed for construction from the Meadows of
Bloomfield development (City Project No. 351) south of 135 Street West at Bacardi Avenue,
north approximately 700 feet, and then stubbed north along Bacardi Avenue for future extension.
An 8 -inch PVC lateral main is proposed to be installed in the northern boulevard of 135 Street
West from Bacardi Avenue west approximately 1,000 feet, and then stubbed to service future
development north of 135 Street West, mainly adjacent to Keegan Lake. This proposed
improvement is in accordance with the North Central Sanitary Sewer Study.
Additionally, it is proposed that an 8 -inch lateral sewer be extended west from Bacardi Avenue
along 135 Street West to provide sanitary sewer service to properties immediately adjacent to
the roadway. Such installation is in accordance with the proposed layouts as shown in the
NCSSS. Sanitary sewer stubs would be provided for future development, and existing properties
would be given the option to connect to the sanitary sewer via one of these stubs. Benefiting
properties would be assessed for the total cost of the lateral sanitary sewer improvements.
The proposed sanitary sewer improvements can be found in Figures 3 -4 in Appendix A.
5.3 Trunk Water Main
A 16 -inch DIP trunk water main is proposed for construction along the entire length of 135
Street West, as well as south of Bacardi Avenue to the proposed water tower site as part of this
project. The trunk water main will be connected to existing 16 -inch trunk and 8 -inch lateral DIP
stubs at the east end of the Harmony Addition, Birchwood Avenue, south of Bacardi Avenue,
and at Autumn Path. Additional 16 -inch DIP stubs will be placed at Akron Avenue, Bacardi
Avenue, and other intermediate locations as outlined in the City's Draft Comprehensive Water
System Plan. Additional 8 -inch DIP stubs will be placed at locations where future roads are
proposed to be installed, mainly at quarter section lines, or every 1,300 feet.
The proposed trunk water main improvements can be found in Figures 2 -7 in Appendix A.

5.4 Raw Water Main
According to the City's Draft Comprehensive Water Supply Plan, the area located north of 135
Street West and east of Bacardi Avenue has been identified as the location for future municipal
water supply wells. The Draft Comprehensive Water Supply Plan identifies a future water
treatment plant at the Bacardi Tower site In order to accommodate the transport of raw water
from future municipal water supply wells to a water treatment facility, raw water mains are being
proposed for installation along 135 Street West between Bacardi Avenue and Akron Avenue.
Raw water mains have the same components as trunk water mains, but are generally much larger
to accommodate larger flows. The proposed raw water main would consist of a 36 -inch DIP
main installed for approximately 750 feet south of Bacardi Avenue to the proposed water
tower /treatment plant; a 24 -inch DIP main installed along 135 Street West from Bacardi
Avenue to Akron Avenue; and 16 -inch DIP stubs at Bacardi Avenue, Autumn Path, and Akron
Avenue for future connection to municipal water supply wells.
The proposed raw water main improvements can be found in Figures 3 -7 in Appendix A.
5.5 Storm Sewer
New lateral storm sewer will be designed and constructed along the entire length of the project
area to provide drainage from roadway surfaces. Additionally, trunk storm sewer improvements,
including a new culvert within Mare Pond crossing 135 Street West, six stormwater ponds, as
well as outlet pipes for individual wetlands in the area, are also being proposed The purpose of
the individual stormwater ponds is to provide treatment of roadway runoff prior to discharging
via the trunk storm sewer system into one of the four designated wetlands located in the project
area. All storm sewers would meet Municipal State Aid standards and would be in accordance
with the City of Rosemount's Comprehensive Stormwater Management Plan.
Proposed storm sewer improvements can be found in Figures 2 -7 in Appendix A.
5.6 Wetlands
The proposed roadway widening will impact Mare Pond on the north and south sides of 135
Street West. Mare Pond (DNR -012W, WL -1533, WP -379) is located immediately east of
Bacardi Avenue, and is connected via a culvert pipe under 135 Street West. The anticipated
impact of filling in the wetland area is approximately 43.241 square feet (0.99 acres). In
accordance with the City of Rosemount Comprehensive Wetland Management Plan, Mare Pond
is considered a "preserve" wetland, meaning that the wetland impacts caused by construction
need to be mitigated at a rate of three -to -one, which is 129,723 square feet (2.97 acres). This
mitigation is proposed to occur onsite, and consists partially of the construction of new
stormwater treatment ponds, as well as the construction of "wetland buffers," which are
permanent easements dedicated to consist of wetland habitat immediately adjacent to wetland
areas, throughout the project area. One new stormwater treatment pond (Pond 3) would be
located adjacent to Mare Pond, and would serve primarily for treatment of stormwater runoff

from 135 Street West, prior to discharging into Mare Pond. Additional mitigation would occur
along the west side of Mare Pond, within Meadows Park, as well as north of 135 Street West.
The majonty of wetland mitigation for Mare Pond is proposed to be provided in these two areas.
Additional wetlands in the project area are not anticipated to be directly impacted by the
widening of 135 Street West The wetland located east of Keegan Lake (KL -2471, WP -359),
also considered a "preserve" wetland, will not be disturbed by construction activities. This
wetland will receive treated stormwater runoff from a treatment pond (Pond 1) located
immediately east of this wetland.
Another wetland located approximately 1,000 feet west of Bacardi Avenue, and immediately
north of the Biscayne Point North development (KL -1568, WP -384), is proposed to be expanded
for the remainder of the Mare Pond wetland mitigation. Another stormwater treatment pond
(Pond 2) would be located adjacent to, and discharge treated water to this wetland.
The fourth wetland (WL -1560, WP -382), located east of Mare Pond, would receive treated
stormwater runoff from a fourth stormwater treatment pond, located north of the proposed
Autumn Path (being constructed as part of the Meadows of Bloomfield development). This
wetland would be connected via trunk storm sewer to Mare Pond.
Finally, a fifth stormwater treatment pond (Pond 5) is proposed to be constructed immediately
west of Akron Avenue and south of 135 Street West. This stormwater treatment pond would be
constructed as a temporary pond, and could be relocated as development south of 135 Street
West occurs, at the expense of a future developer. This pond is proposed to discharge east across
Akron Avenue into existing ditches along 135 Street West.
The proposed wetland impact locations, as well as proposed mitigation areas and stormwater
pond locations, can be found in Figures 2 -7 in Appendix A.
5.7 Right -of- Way/Easements
The existing nght -of -way along 135 Street West east of the Harmony development varies in
width and location. In some locations, the right -of -way has been defined in terms of prescriptive
rights, meaning that the right -of -way vanes based on the width of the ditches and as bounded by
existing private utility easements. It is proposed as part of this project that a minimum of 100
feet of total nght -of -way be acquired along the entire length of the road. This will allow for the
construction of side slopes and embankments, the installation of both public and private utilities,
and the clarification of nght -of -way location and property lines. In some locations, additional
permanent easements will be required for stormwater treatment pond construction, and
temporary construction easements will be required for any potential encroachments during
construction.

(East Tract Line of Harmony to Akron Avenue)
Street and Utility Improvements and Appurtenant Work
City Project No. 387
WSB Project No. 1591 -02
Page 9
It is anticipated that 148,000 square feet (3.40 acres) of permanent right -of -way, 485,600 square
feet (11.15 acres) of permanent easement, and 8,000 square feet (0 18 acres) of temporary
construction easements will be necessary for construction of the proposed improvements. While
the estimate for permanent right -of -way has been well defined, the estimates for permanent and
temporary easements are still preliminary A more accurate figure for the total temporary
construction and permanent easement area required for construction will be determined during
the final design phase of the project
5.8 Private Utilities
It is anticipated that utility relocations and coordination will be necessary along the length of
135 Street West. Private utility companies are responsible for the costs to relocate utilities
serving local residents. Pnvate utilities with local service lines in the area include Xcel Energy
(power and gas) and Frontier Communications (telephone).
The costs to relocate aerial electric transmission lines are shared between the pnvate utility
company and the City. An aerial transmission line operated by Xcel Energy runs along the entire
length of 135 Street, and a portion of it will need to be relocated. The extent and exact cost of
such relocation is not known, and City representatives are conducting ongoing meetings with
Xcel Energy to determine the final costs and timing of transmission line relocations. For the
purposes of this feasibility report, an estimated relocation cost, based on previous discussions
with Xcel Energy, has been included in the cost for the proposed surface improvements.
Additionally, there are natural gas and petroleum pipelines that exist within the project area, but
are not anticipated to be relocated. Koch Pipeline and Magellan Midstream Partners each have
petroleum lines within a pipeline easement along the south side of 135 Street West, from
approximately 1,300 feet west of Bacardi Avenue east to approximately 100 feet east of Bacardi
Avenue, where they cross 135 Street West and run to the northeast out of the project area.
Northern Natural Gas has two pipelines crossing 135 Street at Bacardi Avenue. A third
pipeline crosses Bacardi Avenue north of 135 Street at the edge of the proposed construction
Iirriits.
5.9 Permits/Approvals
The anticipated permits and approvals that will be required for the 135 Street West
reconstruction and the respective regulatory agencies are listed below:

6. FINANCIiNG
6.1 Opinion of Cost
Detailed opinions of cost can be found in Appendix B of this report. The opinions incorporate
estimated 2006 construction costs and include a 10% contingency and 30% for all related
indirect costs (legal, administrative, engineering, and financing items).
Table 1 provides a summary of the opinion of cost for 135 Street West:
As previously mentioned, it is anticipated that land acquisition will need to occur in order to
construct the 135 Street West improvements as proposed. The cost of permanent right -of -way
and permanent utility easements varies based on location, existing property use, and the amount
of right -of -way being obtained per property. As such, the cost for nght -of -way acquisition has
not been included in these cost estimates. Since nght -of -way is being obtained from property
owners who will benefit from and be assessed for the proposed improvements, the negotiated
right -of -way costs will be reflected in the total proposed property assessments.

6.2 Funding
Financing for this project will come from a combination of sources including Special
Assessments, Dakota County funds, City Sanitary Sewer Core Funds, City Water Main Core
Funds, City Stoi Water Core Funds, City Street CIP Funds, and previous cash deposits by
adjacent property developers for roadway improvements. Detailed cost distnbution and
assessment calculations can be found in Appendix C.
6.2.1 Dakota County
As part of the County Road 38 turnback agreement, Dakota County has provided
$2,240,000 toward the second phase reconstruction and upgrade of the roadway.
6.2.2 Sanitary Sewer Core Fund
The City's Sanitary Sewer Core Fund is available to fund trunk sanitary sewer
improvements throughout the City of Rosemount. For the 135 Street West portion of
the project, there is approximately $339,300 in estimated trunk sanitary sewer
improvements.
6.2.3 Water Main Core Fund
The City's Water Main Core Fund is available to fund any trunk water main
improvements throughout the City of Rosemount. Trunk improvements can include both
trunk water main and raw water main. Trunk water main improvements along 135th
Street West are estimated at $1,626,800.
6.2.4 Storm Sewer Core Fund
The City's Storm Sewer Core Fund is available to fund any trunk storm sewer
improvements throughout the City of Rosemount. Trunk improvements can include
installing outlet structures within ponds, replacing existing culvert pipes between ponds,
and connecting storm sewer ponds within the trunk system as outlined in the City's
Comprehensive Stormwater Management Plan. Trunk storm sewer improvements along
135 Street West are estimated at $90,400.
6.2.5 Street Capital Improvement Program (CIP)
The City's Street CIP fund is responsible for funding portions of the costs associated with
upgrading and maintaining City streets. The dedicated CIP funding for individual
projects can vary based on street size, use, location, and estimated construction costs.
The City of Rosemount has budgeted up to $280,000 for the proposed 135 Street West
improvements. According to the current cost distnbution, the City of Rosemount would
only need to contribute an estimated $225,300 for the proposed improvements.

6.2.6 Cash Payments by Developers
As a requirement of the plat approval for the Meadows of Bloomfield development,
located south of 135 Street West, east of Bacardi Avenue, the developer was required to
submit a cash payment of $265,000 to pay for the costs of the roadway and access
improvements along 135 Street West.
Similarly, the developer of the Biscayne Point North development was required to submit
a cash payment of $65,900 to pay for the costs of the upgrade of 135 Street West. The
total amount of pre -paid assessments contributed to the project is $330,900.
6.2.7 Special Assessments
Properties with front footage or accessible acreage along 135 Street West are proposed
to be assessed on a front footage basis. According to the City's 2005 Fee Resolution, for
complete street reconstruction projects along gravel roads, assessments for the total cost
of the improvement can be levied against benefiting properties. Since 135 Street West
is both a County Road turnback and a Municipal State Aid street, outside funding
sources, such as Dakota County turnback funds and Street CIP funds, are also being used
for the proposed reconstruction.
The assessment cost for the 135 Street West improvements is proposed at $110 per front
foot for properties directly fronting 135 Street West. For properties with developable
acreage that would benefit from the proposed roadway improvements and have access to
their property from 135 Street West, the front footage assessment was divided evenly
among the benefiting properties. Total street assessments are estimated at $1,290,200.
Additionally, assessments are proposed to be levied against properties that would
immediately benefit from the installation of lateral sanitary sewer. The total cost of the
lateral sanitary sewer is proposed to be assessed to five benefiting properties along 135
Street West between Birchwood Avenue and Bacardi Avenue. Total sanitary sewer
assessments are estimated at $50,600.

8. FEASIBILITY AND RECOMMENDATION
Due to the continued residential development in this area, increased traffic, accidents, and
deteriorating streets, 135` Street West should be reconstructed and upgraded to provide
improved traffic flow, safer traffic movements, and increased pavement ndeability.
The total estimated cost of the street and utility improvements for 135 Street West is
$6,193,500. Funding will be provided through a combination of special assessments, property
development fees, Dakota County funds, City Sanitary Sewer Core Funds, City Water Main Core
Funds, and City Street CIP Funds.
This project is feasible, necessary, and cost effective from an engineenng viewpoint. We
recommend the street reconstruction and new trunk and lateral sanitary sewer, trunk water main,
raw water main, and storm sewer installation along 135` Street West, from east tract line of the
Harmony development east to Akron Avenue (County Road 73), as outlined in this report.
