1. EXECUTIVE SUMMARY
The Kenrick Avenue Improvement Project, City Project No. 18-03, was initiated by the City’s Pavement
Management Program. Improvements are proposed along Kenrick Avenue from approximately 200 feet
south of Maple Island Road (Burnsville, MN) to approximately 340 feet north of Kenrick Circle, which is
just south of the southerly driveway entrance to Mills Fleet Farm (17070 Kenrick Avenue). The project is
approximately 7,550 feet (1.43-miles) in length.
The Kenrick Avenue Improvement Project includes roadway reclamation improvements based on
pavement ratings, current roadway conditions and utility needs in the area, as well as the overall Capital
Improvement Plan (CIP) budget. Reclamation of the existing bituminous pavement and roadway
reconstruction, consisting of complete curb and gutter replacement, spot concrete sidewalk replacement,
pedestrian ramp installation, and new pavement installation, are recommended for this corridor of
Kenrick Avenue.
Replacing portions of the City’s deteriorating utility infrastructure in conjunction with the proposed street
improvements provides an opportunity to minimize the replacement costs and traffic disruptions
associated with the work. Proposed utility improvements include the following:
▪ Installation of corrosion protection for the existing watermain throughout the length of the Project.
▪ Replacement of a section of existing ductile iron watermain near the intersection with 167th Street
to a corrosion resistant pipe material.
▪ Repair or replacement of structurally deficient storm sewer manholes along with the installation of
additional storm sewer facilities to improve drainage.
▪ Replacement of all structurally deficient storm sewer and all sanitary sewer manhole castings that
do not meet current City Standards, including the installation of chimney seals.
The total estimated project cost for the Kenrick Avenue Improvement Project is $2,961,260, which
includes a ten percent (10%) contingency and twenty-eight percent (28%) indirect costs for legal,
engineering, administrative, and financing costs (Opinion of Probable Cost can be found in Appendix B).
The Project is proposed to be funded through City funds and special assessments to benefitting property
owners.

2. STREET IMPROVEMENT PROGRAM
2.1 Introduction
2.1.1 Authorization
On July 5, 2017, the Lakeville City Council authorized the preparation of an engineering feasibility
report for the Kenrick Avenue Improvement Project. This project is included in the City’s 2017-
2021 CIP and has been designated as City Project No. 18-03.
2.1.2 Scope
This report investigates the feasibility of proposed street and utility improvements identified within
the City’s Pavement Management Program and CIP for 2018. This improvement project was
initiated due to the aging condition of the existing roadway section. The existing average OCI
value for Kenrick Avenue is 32.4 using an OCI scale of 0 to 100 (with zero representing a failing
street section and 100 representing a new street section free of deficiencies). Streets with OCI
values less than 35 are considered to be in failing condition.
Improvements outlined within this report include street reconstruction, complete curb and gutter
replacement, spot concrete sidewalk replacement, pedestrian ramp installation, installation of
corrosion protection, sanitary sewer repairs, and storm sewer improvements.
2.1.3 Data Available
Information and materials used in the preparation of this report include the following:
▪ City of Lakeville Record Plans
▪ Field Observations of the Area and Discussions with City Staff
▪ Boring Logs, Braun Intertec, dated November 6, 2014 and December 10, 2014
▪ Utility Inspection Notes (Completed by the City of Lakeville and WSB Staff)
▪ Private Utility Record Drawings
▪ City of Lakeville Street Reconstruction Assessment Policy
2.2 General Background
2.2.1 Project Location
The street proposed for improvements is Kenrick Avenue from a point approximately 200 feet
south of the intersection with Maple Island Road (Burnsville, MN) to approximately a point
approximately 340 feet north of Kenrick Circle, adjacent to the south driveway entrance to
Mills Fleet Farm (17070 Kenrick Avenue).
2.3 Existing Conditions
2.3.1 Public Roadway Surface
The existing bituminous surface on Kenrick Avenue is aging and experiencing various severities
of distress including block, transverse, and longitudinal cracking. Well over sixty percent (60%) of
the curb and gutter is structurally deficient with cracking, settlements, and weed overgrowth in
joints, resulting in isolated drainage issues. Concrete sidewalks are located within the project
area along the entire east side of Kenrick Avenue, and along the west side from 162nd Street
West (CSAH 46) to Kenrick Loop. The concrete sidewalks are generally in good condition, with
minor cracking, settlements and heaving. Additionally, a majority of existing pedestrian curb
ramps do not meet the current Americans with Disabilities Act (ADA) design standards.

City of Lakeville Project No. 18-03
WSB Project No. R-010529-000 Page 3
Table 1 below provides a summary of existing street conditions within the Kenrick Avenue
Improvement Project.
2.3.2 Public Storm Sewer
City record drawing information indicates that storm sewer facilities exist throughout the project
area. Runoff from the Kenrick Avenue Improvement Project area is tributary to the Crystal Lake
Stormwater District. The City’s Public Works Department has reported that the majority of the
existing storm sewer infrastructure has historically performed acceptably. City Staff along with
WSB representatives have completed an inspection of the storm sewer system and have
provided recommendations for repairs and replacement that include: castings, adjustment rings,
and structure replacement. Localized drainage issues were identified by City staff at each of the
three parking lot entrances to Mills Fleet Farm along Kenrick Avenue.
2.3.3 Public Watermain
City record drawing information indicates that the existing watermain located within the
Kenrick Avenue Improvement Project is primarily 12-inch ductile iron pipe (DIP) with some
segments of 8-inch DIP, installed between the years of 1980-1986. The City’s Public Works
Department has reported minimal watermain maintenance issues within the project area, except
for a section of watermain located at the intersection with 167th Street West. City staff performed
a soil analysis in this area and discovered the existing soils are corrosive to ductile iron pipe. An
inspection of the hydrants and gate valves within the project area revealed that one hydrant valve
is seized and two hydrants were installed without gate valves.
2.3.4 Public Sanitary Sewer
The existing sanitary sewer located within the Kenrick Avenue Improvement Project north and
east of Kenrick Loop is 8-inch polyvinyl chloride (PVC) pipe, and the sanitary sewer south of
170th Street West is 8-inch DIP forcemain. No north/south sanitary sewer pipe exists along
Kenrick Avenue from 170th Street West to Kenrick Loop, however, there is a 1.5-inch PVC service
crossing at 167th Street West that serves the Metro Transit Park and Ride facility.
In the summer of 2017, the City’s Public Works Department televised the sanitary sewer and
inspected all of the sanitary sewer manholes. All of the sanitary sewer manhole structures were
identified as being in good condition and therefore do not require replacement. All sanitary
manhole castings and adjustment rings will be replaced and installed with chimney seals to
conform to City specifications, reduce the potential for inflow/infiltration issues, and to extend the
useful life of the manholes.

2.4 Proposed Improvements
2.4.1 Public Roadway Surface
Surface improvements recommended with the Kenrick Avenue Improvement Project are intended
to extend the life of the existing roadway system, improve isolated drainage issues, and improve
the ride quality of the roadway.
Surface improvements include full-depth bituminous reclamation. Reclamation is the process by
which the existing deteriorating roadway surface is reclaimed and mixed with the existing
aggregate base and reused as aggregate roadway base for the new street section. Street grades
will closely match the existing grades so as to minimize construction impacts to adjacent
properties. Minor adjustments to select roadway vertical profiles will be proposed to improve
drainage conditions. Over sixty percent (60%) of the existing curb and gutter within the project is
structurally deficient, experiencing joint separation with weed growth, cracks, and other signs of
structural deficiencies, and therefore, complete concrete curb and gutter replacement is
proposed.
Kenrick Avenue is designated as Major Collector in the City’s Comprehensive Transportation
Plan and will be reclaimed and reconstructed in accordance with the City’s collector roadway
design standards. The Kenrick Avenue street section is proposed to consist of the following
section: 2 inches of bituminous wearing course, 4 inches of bituminous base course, and a
minimum of 8 inches of reclaimed aggregate base over an acceptable, compacted subgrade.
Appendix A illustrates the proposed collector roadway section.
All existing pedestrian curb ramps within the project area that do not conform to current ADA
design standards will be reconstructed, and all damaged or structurally deficient sidewalk panels
will be replaced, including those panels along the east side of Kenrick Avenue, south of
170th Street that are affected by curb and gutter replacement.
2.4.2 Public Storm Sewer
Reconstruction of the street provides a timely opportunity to improve drainage conditions and
increase the longevity of the street section by installing additional storm sewer facilities. Structures that have been identified as needing rehabilitation will undergo necessary interior repairs. It is the City’s practice to install storm sewer castings meeting current City Standards on all catch basins within the project area. Therefore, structure top slabs or entire structures will be
replaced to accommodate the transition. Potential drainage improvements to be evaluated with
final design of the project include enhancements to the existing storm sewer facilities and the
addition of catch basins along Kenrick Avenue, south of 170th Street, adjacent to Mills Fleet Farm,
where known drainage issues were identified.
2.4.3 Public Watermain Improvements
It is proposed that in conjunction with the surface improvements within the Project, the service life
of the existing watermain systems be extended by installing corrosion protection, in addition to
section replacement with a non-corrosive pipe material. Soil borings collected in 2014 revealed
the soils along Kenrick Avenue are corrosive to iron pipe. Installation of corrosion protection will
directly connect the iron watermain pipe to a more easily corrodible material, or “sacrificial
anode,” which corrodes first instead of the iron watermain, thus reducing the rate of deterioration
of buried iron pipes. This effort will extend the service life of the existing watermain without
replacing the entire watermain system. Corrosion protection has been shown to extend the
service life of the watermain at a lower cost than pipe repairs or main replacements.
In addition to the installation of corrosion protection within the Kenrick Avenue Improvement
Project area, all watermain bolts at existing hydrants and watermain valve locations will be
replaced with stainless steel bolts, which are more resistant to the corrosive nature of the
underlying soils.
Feasibility Report
Kenrick Avenue Improvement Project
City of Lakeville Project No. 18-03
WSB Project No. R-010529-000 Page 5
Additionally, approximately five hundred feet (500’) of existing DIP watermain north and south of
the intersection with 167th Street West will be replaced with non-corrosive PVC pipe due to
deterioration of the existing pipe and frequent break history experienced at this location.
2.4.4 Public Sanitary Sewer Improvements
Sanitary sewer manholes within the project area will receive new rings, castings, and external
chimney seals as part of the project to reduce the potential for inflow and infiltration (I & I) issues
and reduce the frequency of maintenance repairs.
2.4.5 Public Street Sign Replacement
All existing street signs within the project will be replaced with new street signs that meet the
Federal Highway Administration’s (FHWA) requirements for retro-reflectivity.
2.4.6 Mailbox Replacement
It is the City’s intent to salvage and reinstall all existing mailboxes and mailbox supports that may
be impacted with construction. In the event the condition of the existing mailbox support warrants
replacement prior to reinstallation, the City is proposing to salvage the existing mailbox and install
a new mailbox support that will meet both City Standards and United States Postal Service
(USPS) requirements.
2.4.7 Permits/Approvals
An NPDES permit for construction activity will be required since more than one (1) acre will be
disturbed by construction activities with the project.
A Dakota County Work in Right-of-Way user registration will be required for work associated with
matching into 162nd Street/CSAH 46 and for any county roads that may be used as a haul route
for the project. Additionally, construction activities at the intersection with 162nd Street/CSAH 46
will require coordination with Dakota County and MnDOT to ensure intersection operations are
maintained during signal loop disruptions.
2.4.8 Construction Access/Staging
The contractor will be responsible for providing access to all properties throughout the Project.
Adequately signed detours will be identified to direct traffic around the construction zones and
notify users of the increased truck and construction activity.
Construction will be phased such that work south of 162nd Street/CSAH 46 will begin in the
beginning of July as to minimize the impact to businesses during the late spring/early summer
months. Access to Metro Transit’s Kenrick Avenue Park and Ride facility must also be
maintained during construction. Detailed construction phasing plans will be developed with final
design of the project.
2.4.9 Public Involvement
A neighborhood meeting was held to discuss the proposed improvements on June 21, 2017 for
all property owners within the proposed project area. Information regarding the proposed
improvements, funding, schedule, and impacts associated with the project were discussed.
Comment cards were made available to attendees at the meetings, however none were filled out
and submitted to the City. City staff indicated that there was general approval and desire for the
project.

3. FINANCING
3.1 Opinion of Cost
A detailed opinion of cost for the Kenrick Avenue Improvement Project can be found in Appendix B of this
report. The opinion of cost incorporates estimated 2018 construction costs and include a ten percent
(10%) contingency factor. Indirect costs are projected at twenty eight percent (28%) of the construction
cost and include engineering, legal, financing, and administrative costs.
3.2 Funding
Financing for the street and storm sewer improvements within the Kenrick Avenue Improvement Project
will come from City Funds and Special Assessments.
The watermain repairs are proposed to be financed by the City’s Water Operating Fund. The sanitary
sewer repairs are proposed to be financed by the City’s Sanitary Sewer Operating Fund.
Special Assessments to benefitting properties are proposed to fund forty percent (40%) of the assessable
roadway section and storm sewer improvements identified to be reconstructed for the project, with the
remaining sixty percent (60%) funded using City Funds. Assessments for this project were calculated on
a front foot basis as identified in the City’s Assessment Policy, and were prorated based on assessable
front footage of benefitting properties. As much of the frontage along Kenrick Avenue is not assessable
(specifically, all of I-35 frontage along the west side of Kenrick Avenue), the specially assessed share
(40%) has been prorated to reflect only that frontage that can be specially assessed (52.92%), as shown
below.

Standard penetration test borings were advanced by 3 1/4” or 6 1/4”
ID hollow-stem augers unless noted otherwise, Jetting water was used
to clean out auger prior to sampling only where indicated on logs.
Standard penetration test borings are designated by the prefix “ST”
(Split Tube). All samples were taken with the standard 2” OD split-tube
sampler, except where noted.
Power auger borings were advanced by 4” or 6” diameter continuous-
flight, solid-stem augers. Soil classifications and strata depths were in-
ferred from disturbed samples augered to the surface and are, therefore,
somewhat approximate. Power auger borings are designated by the
prefix “B.”
Hand auger borings were advanced manually with a 1 1/2” or 3 1/4”
diameter auger and were limited to the depth from which the auger could
be manually withdrawn. Hand auger borings are indicated by the prefix
“H.”
BPF: Numbers indicate blows per foot recorded in standard penetration
test, also known as “N” value. The sampler was set 6” into undisturbed
soil below the hollow-stem auger. Driving resistances were then counted
for second and third 6” increments and added to get BPF. Where they
differed significantly, they are reported in the following form: 2/12 for the
second and third 6” increments, respectively.
WH: WH indicates the sampler penetrated soil under weight of hammer
and rods alone; driving not required.
WR: WR indicates the sampler penetrated soil under weight of rods
alone; hammer weight and driving not required.
TW indicates thin-walled (undisturbed) tube sample.
Note: All tests were run in general accordance with applicable ASTM
standards.
