th
Gerdine Court (cul-de-sac located on the west side of Gerdine Path, opposite Lower 170
Street Court)
The deteriorated condition of the existing roadway surfaces and the drainage issues experienced
along these streets require the proposed necessary improvements. Additionally, there are several
areas within the project area that have experienced multiple water main breaks, including:
Galaxie Way, Gannon Way, Garcia Way, and portions of Gerdine Path. 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 utility replacement. The proposed utility improvements also include the
installation of minor storm sewer additions to address localized drainage issues and the repair of
structurally deficient sanitary sewer manholes.
Reclamation of the existing bituminous pavement and roadway reconstruction is recommended
for all streets within the project area, except:
Galaxie Way
Gannon Court
Gannon Way
Garcia Way
Gerdine Court
th
A portion of Gerdine Path (from Dodd Boulevard to 168 Street)
th
Lower 170 Street Court
The aforementioned streets will require complete reconstruction due to the nature of the soils in
these areas. Structurally deficient concrete curb and gutter and concrete sidewalk will be
replaced within the project limits. Concrete sidewalk panels with faulted joints are proposed to
be replaced as a part of the project.
$8,636,000
The total estimated project cost for the 2012 Street Reconstruction Project is which
includes a 10% contingency and 24% indirect costs for legal, engineering, administrative, and
financing costs. The project is proposed to be funded through special assessments to benefitting
property owners and City funds.
The project is proposed to be completed in 2012, including all restoration items. The project is
feasible, necessary, and cost-effective from an engineering standpoint and should be constructed
as proposed herein.

2.3 Existing Conditions
2.3.1 Surface
Streets within the proposed improvement area are aging and experiencing various
severities of distresses including alligator cracking, block cracking, transverse cracking,
longitudinal cracking, and localized drainage issues. All project areas contain
landscaping, trees, and numerous other private improvements beyond the edge of the
roadway and within City right-of-way. Concrete sidewalks of varying widths (between
42 inches and 60 inches) are located throughout the project area, and 8-foot-wide
bituminous trails exist within Bunker Hills Park, Cedar Highlands Park, Fairfield Park,
Parkview Park, and Sleepy Hollow Park.
Some of the existing sidewalk panels within the 2012 Street Reconstruction Project area
have heaved due to the root system of mature trees within close proximity of sidewalks.
Additionally, several of the sidewalk panels within the project area are aging and
showing various signs of structural distress, such as spalling, cracking, and faulted joints.
The majority of pedestrian curb ramps within the project area do not meet current ADA
accessible design standards.

2.3.2 Storm Sewer
City record drawing information indicates that storm sewer facilities already exist within
much of the 2012 Street Reconstruction Project area. Runoff collected by the existing
catch basins travels through existing storm sewer pipe and outlets into either:
Regional Stormwater Basin NC-34-1, which is located south and west of Gerdine
Path, north of and adjacent to Dodd Boulevard (CSAH 9). Gerdine Court, Lower
thth
170 Street Court, Gerdine Path south of Gerdine Court/Lower 170 Street Court,
and that portion of Gannon Way southwest of the road’s highpoint (located at
approximately 17070 Gannon Way) all drain to this regional stormwater basin.
The west branch of North Creek. Runoff collected by the existing storm sewer
facilities within the project area is discharged directly into North Creek at
numerous points throughout the project area.
Historically, the existing storm sewer facilities within the 2012 Street Reconstruction
Project area have proved adequate during small rainfall events. Larger rainfall events
have caused the elevation of flow through the North Creek drainage channel to rise
significantly, such that localized flooding occurs in the area between Cedar Avenue
(CSAH 23) and the intersection of North Creek at Flagstaff Avenue. The City of
Lakeville is in the process of updating its hydrologic models, to include an evaluation of
the North Creek drainage channel through the project area, independently from this
project. City staff is also working to permit and coordinate the removal of sediment that
has deposited within the North Creek drainage channel, at the southern end of Fairfield
Park, to improve flow through the channel in that area. The potential to remove existing
vegetation that may be impeding drainage through the North Creek channel is also being
thth
investigated by City staff, in particular, in that area near the intersections of 167/168
Streets and Gerdine Path, adjacent to Bunker Hills Park. It is anticipated that the
aforementioned sediment removal and potential vegetation clearing will take place within
the upcoming winter months, prior to the start of construction associated with the 2012
Street Reconstruction Project.
At the September 22, 2011, Neighborhood Meeting, a number of residents approached
City staff with concerns regarding drainage along Gannon Way, including the lack of
public drain tile facilities in this area. Many residents in this area have indicated that they
have private drain tile facilities installed on their properties that daylight near the street.
Residents and City Public Works staff have also identified locations along Gannon Way
in which a suspected high groundwater table flows from the front yards of properties
along Gannon Way and onto the street during winter months, causing severe icing
problems. City staff collected samples of this water during the 2010/2011 winter season
to determine if this runoff was originating from a leaking public water supply. Testing of
these samples revealed the water was not chlorinated, and therefore, was not suspected to
be originating from a leaking water main or hydrant. While borings performed during the
fall of 2011 did not reveal high groundwater tables in the area, surface water discharge
onto Gannon Way during the winter months is likely contributing to the rapid
deterioration of the pavement in this area.

Other localized drainage issues were identified by residents at the following intersections,
where little to no storm sewer currently exists:

167 Street and Franchise Way
th
167 Street and Galena Avenue
th
168 Court and Galena Avenue

Frazer Path and Forbes Court
2.3.3 Water main
The majority of the existing water main located within the 2012 Street Reconstruction
Project area is cast iron pipe (CIP). Twelve-inch CIP exists in Gerdine Path, 8-inch CIP
exists in Foliage Avenue, and 6-inch CIP exists in the majority of local residential streets
located north of Dodd Boulevard (CSAH 9). Existing six-inch ductile iron pipe (DIP) is
th
in Gannon Court, Gerdine Court, and Lower 170 Street Court, while 8-inch DIP is in
Gannon Way. Existing six-inch DIP is in all streets within the 2012 Street
Reconstruction Project area located south of Dodd Boulevard (Florida Court, Forbes
Court, Forfar Court, Franchise Way, Frazer Path, Gage Avenue, and Gage Way). There
is an existing 16-inch well collection pipe located along the east side of Gerdine Path,
between the two street intersections with the Gannon Way loop, that was constructed in
2004 with DIP encased in a polyethylene wrap.
City maintenance records indicate a number of recent water main breaks in the following
areas:
Galaxie Way (seven recorded breaks)
Gannon Way (two recorded breaks)
Garcia Way, directly west of the intersection with Gerdine Path (three recorded
breaks)
th
Gerdine Path, from Dodd Boulevard to 168 Street (seven recorded breaks)
The quantity and frequency of water main breaks in this area has lead to long-term and
costly maintenance issues for the City. The age of the existing pipe in this area would not
suggest that the water main breaks are simply the result of an aging infrastructure. Soil
samples were collected with the geotechnical borings earlier this fall to test for
corrosivity in the soils (pH, oxidation-reduction, electrical resistivity, chloride content,
and sulfate content) to determine if the native soils were contributing to failure of water
main pipe in this area. The City also conducted a water main leak detection survey and
evaluated all of the water main valves within the project during the fall of 2011.

2.3.4 Sanitary Sewer
The existing sanitary sewer within the 2012 Street Reconstruction Project Area is
comprised of 8-inch PVC (plastic) pipe (within all of the local residential streets south of
Dodd Boulevard, Gerdine Path from Dodd Boulevard to Garcia Way, Gannon Court,
th
Gannon Way, Gerdine Court, and Lower 170 Street Court), 9-inch VC (clay) pipe
(along a majority of the local residential streets north of Dodd Boulevard and Gerdine
th
Path from 164 Street to Flagstaff Avenue), 15-inch VCP (Foliage Avenue from Gerdine
th
Path to Dodd Boulevard), 12-inch RC (concrete) pipe (Gerdine Path from 164 Street to
th
approximately 167 Street), and 30-inch RC (concrete) Metropolitan Council sanitary
th
sewer pipe (Gerdine Path just south of 167 Street).
In the fall of 2011, the City’s Public Works Department televised the sanitary sewer and
inspected all of the sanitary manholes. Six (6) sanitary sewer manholes were identified
as needing new rings and/or castings, and are proposed to be repaired as a part of this
project. Additionally, all sanitary sewer manholes within the street reconstruction area
will receive external chimney seals as a part of the project to reduce the potential for I & I
issues and reduce the frequency of maintenance repairs. City staff is proposing to make
any necessary sanitary sewer pipe repairs identified in the sanitary sewer televising tapes
by trenchless construction methods, and outside of the scope of the 2012 Street
Reconstruction Project.
2.3.5 Wetlands
No wetland impacts are anticipated with the proposed improvement project.
2.4 Proposed Improvements
2.4.1 Surface
Roadway reclamation, in which the existing deteriorating roadway surface is reused as
aggregate roadway base, is proposed for the streets located in areas with sandy native
soils due to the level of distress the bituminous pavement in the area is experiencing, and
will consist of the complete reclamation of the existing bituminous roadway for re-use as
roadway aggregate base. Structurally deficient concrete curb and gutter and concrete
sidewalk will be replaced within the project limits. Concrete sidewalk panels that have
faulted at the joints are proposed to be replaced as a part of the project. All streets and
sidewalks within the project will be reconstructed to their current widths to minimize
impacts. All pedestrian ramps within the project area will be brought up to current ADA
accessibility design standards.

Page 10
Reclamation of the local residential streets to the City’s standard 7-ton design is proposed
to consist of the following section: 1 ½ inches of bituminous wearing course, 2 inches of
bituminous base course, and 6 inches of reclaimed aggregate base over 12 inches of an
acceptable, compacted subgrade. All residential streets within the project will be re-
established to include a 6-inch crown, further promoting drainage within the roadways.
th
Two inches of bituminous wearing course is proposed for Gerdine Path (from 168 Street
to Flagstaff Avenue) and Foliage Avenue (north of Dodd Boulevard), as both streets have
been identified as minor collector roadways by the City’s Comprehensive Transportation
Figures 2and 4Appendix A
Plan, and require a thicker roadway section. of illustrate
these proposed roadway sections in areas with native sandy soils.
Roadway reconstruction is proposed for each of the streets located in areas with clayey
native soils due to the level of distress the bituminous pavement in the area is
experiencing, and will consist of the complete reconstruction of the roadway. Those
streets proposed for complete roadway reconstruction include:
Galaxie Way
Gannon Court
Gannon Way
Garcia Way (to a point approximately 100 feet west of the intersection with
Gerdine Path)
Gerdine Court
th
Gerdine Path (from Dodd Boulevard to 168 Street)
th
Lower 170 Street Court
Reconstruction of the local residential streets to the City’s standard 7-ton design is
proposed to consist of new concrete curb and gutter and the following roadway section: 1
½ inches of bituminous wearing course, 2 inches of bituminous base course, and 6 inches
of Class 5 aggregate base over 12 inches of select granular material. All residential
streets within the project will be re-established to include a 6-inch crown, further
promoting drainage within the roadways. Reconstruction of Gerdine Path from Dodd
th
Boulevard to 168 Street is proposed to include 2 inches of bituminous wearing course, 2
inches of bituminous base course, 8 inches of Class 5 aggregate base over 18-inches of
select granular material, as it is identified as minor collector roadway by the City’s
Figures 3and 5Appendix A
Comprehensive Transportation Plan. of illustrate these
proposed roadway sections in clay soils.
Special Assessments to benefitting properties are proposed to fund 40% of the surface
(and storm sewer) improvements identified for the project, with the remaining 60%
funded using City funds.

2.4.2 Storm Sewer
Reconstruction of the streets also provides the opportunity to improve drainage within the
project areas with the installation of additional storm sewer facilities. Potential drainage
improvements to be evaluated with final design of the project include:
ththth
Installing additional catch basins along 167 Court, 167 Street, 168 Court,
Gage Avenue, Gage Way, Galena Avenue, Gannon Avenue, Garland Way,
Foliage Avenue (south of Dodd Boulevard) and Forbes Court.
2.4.3 Water Improvements
The geotechnical investigation included collecting soil samples within the 2012 Street
Reconstruction Project area to measure the corrosivity of the soils within select areas of
the project. The results of the corrosivity testing indicate the project area does contain
pockets of corrosive soils that impact iron water main pipe. Pockets of corrosive soils
were discovered within Galaxie Way as well as those streets within the southwest area of
the project, north of Dodd Boulevard. It is proposed that in conjunction with the street
improvements identified for 2012, the existing water main also be replaced along the
following streets:
Galaxie Way
Gannon Way
Gannon Court
Garcia Way to a point approximately 100 west of the intersection with Gerdine
Path
Gerdine Court
Gerdine Path from 168th Street to Dodd Boulevard
Lower 170th Street Court
Replacing the existing water main facilities in these areas of the 2012 Street
Reconstruction Project provides a timely and cost-effective solution to what has been a
long-term maintenance issue within the area. It is proposed that the existing cast iron and
ductile iron water main facilities in these areas be replaced with PVC water main pipe to
withstand the corrosive nature of the soils within the project area, reducing the potential
for future water main repairs in the area. All hydrants, services, and curb boxes in these
areas will also be replaced in conjunction with this project.
It is not proposed to replace the existing 16-inch DIP well water collection main located
along Gerdine Path with this project, since this pipe is encased in a polyethylene wrap,
which should protect the pipe from the corrosive effects of the soils in this area.

2.4.4 Sanitary Sewer Improvements
Six (6) sanitary sewer manholes were identified as needing new rings and/or castings, and
will be repaired as a part of this project. Additionally, all sanitary sewer manholes within
the street reconstruction area will receive external chimney seals as a part of the project.
The proposed improvements are considered routine maintenance, and therefore, the costs
associated with the sanitary sewer manhole ring/casting replacements are included in the
surface improvement costs, which are proposed to be funded using a combination of
Special Assessments to benefitting property owners (40%) and City Funds (60%).
2.4.5 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 retroreflectivity.
2.4.6 Mailbox Replacement
Where spot curb and gutter replacement is proposed, it is the City’s intent to salvage and
reinstall the 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.
Those mailboxes and mailbox supports disturbed by complete street reconstruction will
be replaced as a part of this project, consistent with the City’s practice in prior street
reconstruction project areas.It is proposed that mailboxes be removed and replaced
along the following streets:
Galaxie Way
Gannon Way
Gannon Court
Garcia Way to a point approximately 100 west of the intersection with Gerdine
Path
Gerdine Court
Gerdine Path from 168th Street to Dodd Boulevard
Lower 170th Street Court
The existing cluster mailbox systems along Gannon Way are proposed to be replaced
with similar cluster style mailboxes.

2.4.7 Permits/Approvals
An NPDES permit for construction activity will be required since more than 1 acre will
be disturbed by construction activities with the project.
A permit from the Minnesota Department of Health (MDH) will also be required for the
replacement of water main facilities along Galaxie Way, Gannon Court, Gannon Way,
th
Garcia Way, Gerdine Court, Gerdine Path, and Lower 170 Street Court.
A Dakota County Work in Right-of-Way permit will be required for the work within the
Dodd Boulevard (CSAH 9) right-of-way and for any potential detours associated with the
project that will detour traffic onto County roads (Dodd Boulevard/CSAH 9 or Cedar
Avenue/CSAH 23).
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 so as to reconstruct the streets located at the center of the
project first, such that construction truck traffic will not need to access newly
reconstructed streets to complete the project. Detailed construction phasing plans will be
developed with final design of the project.
2.4.9 Public Involvement
A public informational meeting for the proposed project was conducted September 22,
2011. Preliminary information was presented to approximately 70-80 attendees
regarding the proposed improvements, costs, funding, schedule, and impacts associated
with the project. Comment cards were made available to attendees at the meeting.

2.5 Additional Considerations
2.5.1 North Creek Channel Clearing (Cedar Avenue to Flagstaff Avenue)
At the September 22, 2011, Neighborhood Meeting, multiple residents inquired about
proposed drainage improvements within the channel identified as North Creek. Residents
were concerned with some of the drainage issues experienced during large storm events.
The North Creek channel overtops the existing banks, resulting in localized street
th
flooding, specifically, near the intersection of 167 Street and Gerdine Path, adjacent to
Bunker Hills Park. At the time of this report, City staff is working to permit and
coordinate the removal of sediment that has deposited within the North Creek drainage
channel, at the southern end of Fairfield Park, in an effort to improve flow through the
channel in that area. The removal of existing vegetation that may be impeding drainage
through the North Creek channel is also being investigated by City staff in that area near
thth
the intersections of 167/168 Streets and Gerdine Path, adjacent to Bunker Hills Park.
No improvements to the North Creek drainage channel are proposed in conjunction with
the 2012 Street Reconstruction Project at this time.

Re: City Project No. 12-02
WSB Project No. 1715-83
A Neighborhood Meeting was held on Thursday, September 22, 2011 to discuss the proposed
2012 Street Reconstruction Project, City Project #12-02. Approximately 70-80 residents
attended the meeting held at the Parkview Elementary School to discuss the proposed
improvements. The following Staff and WSB & Associates, Inc. representatives were in
attendance:
Chris Petree, City of Lakeville, Operations and Maintenance Director
Troy Grossman, City of Lakeville, Street Superintendent
Zach Johnson, City of Lakeville, Assistant City Engineer
Monica Heil, WSB & Associates, Inc.
Katie Kasper, WSB & Associates, Inc.
The following is a summary from the Question and Answer portion of the presentation:
Question #1 (Q1):
How will the assessments be paid?
Answer #1 (A1):
The City is proposing a 20-year amortization schedule for the assessments.
The interest rate will be determined at the time the bonds are executed. The
rate applied to the 2011 Street Improvement Project was approximately 4.0%.
Q2:
Will I have access to my driveway during construction?
A2:
The contractor will be required to maintain street access during construction. However,
inconveniences due to additional utility work and/or curb replacement may limit access to
properties during working hours. The daily onsite representative will coordinate efforts
with the contractor to limit inconveniences during the project, but there may be instances
when access to properties is limited between the working hours of 7:00 AM and 8:00 PM.

Q3:
I have a new driveway - what is going to happen to my driveway if the curb adjacent to
my driveway is to be replaced?
A3:
It may be necessary to remove a portion of your driveway within the right-of-way in
order to make improvements to structurally deficient curb and gutter. In this case,
driveways will be replaced in-kind, i.e. concrete driveways will be replaced with
concrete, bituminous driveways will be replaced with bituminous. The contractor and
on-site representative will make all necessary efforts to minimize disturbances to
driveways and only remove and replace what is necessary.
Q4:
What are the major factors leading to the deterioration of our streets?
A4:
The age of the streets and drainage issues are likely the biggest factors. Water that is not
draining from the pavement is finding its way into the street subgrade, causing damage
during freeze-thaw cycles.
Q5:
What effect does heavy truck traffic have on our roads? We have three different waste
haulers that pick up garbage, yard waste and recycling in three different trucks.
A5:
Road restrictions are in place every spring, when heavy truck traffic can cause the most
damage to our streets. Spring road restrictions limit truck traffic along these streets to 5-
tons/axel. However, school buses, emergency vehicles, and to a certain extent, waste
haulers, are exempt from these restrictions.
Q6:
What about the frequency of waste hauling vehicles in our neighborhoods? Is there
anything that can be done?
A6:
It is difficult to regulate waste haulers, and this issue has been discussed by the City’s
policy makers over the years. Ultimately, the City’s policy makers have decided to allow
free enterprise in the waste hauling business to continue and to allow multiple waste
haulers to serve the area. However, your concerns regarding waste haulers, and the effect
their vehicles have on your streets, will be included in the comments presented to the City
Council regarding this meeting.
Q7:
Can assessments be paid early without interest?
A7:
Yes. Once the assessment roll is adopted by the City Council, residents can pay their
st
assessments by December 31 of that year to avoid any interest charges.
Q8:
Can assessments be deferred?
A8:
Yes. There is a senior citizen deferment policy for those over 65-years of age. Interest
will continue to accrue until the assessment is paid in full. Additional questions
regarding deferments can be answered by the City’s Finance Director.
Q9:
Can street lights be added to any of the neighborhoods with the project?
A9:
The possibility can be investigated if the there is enough interest within the
neighborhood. Street lighting improvements would be 100% assessed to benefiting
property owners, separate from the street improvement project.

Q10:
Can entire driveways be replaced as a part of the project?
A10:
Not as a part of the City Project. However, property owners can sometimes reach a deal
with the contractor working on the City Project to complete private driveway work.
Q11:
Will mailboxes be impacted with the proposed street improvements? I have landscaping
surrounding my mailbox, will that be replaced?
A11:
The vast majority of mailboxes will be unaffected by construction. Mailboxes in conflict
with any of the proposed street improvements will be salvaged and reinstalled as a part of
the project. If necessary, temporary mailboxes may be installed to accommodate local
mail carriers. The daily on-site representative will coordinate the removal and
replacement of existing mailboxes and, if necessary, the installation of temporary
mailboxes.
Q12:
Will bank-owned properties be assessed?
A12:
Yes. Property owners will not be burdened by properties owned by financial institutions.
The City will bear the cost of the assessment for the property until the property is sold.
At that time, the property owner will be responsible for repaying the assessment.
Q13:
The cul-de-sac I live on seems to have a spring under the existing roadway. Has the City
used drain tile to eliminate drainage issues along roadways?
A13:
Yes. Drain tile has been installed within other street improvement project areas to help
alleviate the effects of high groundwater tables on the existing road sub-grade. Soil
borings will be performed to determine the groundwater elevations within the project
area, and drainage issues such as this will be investigated as a part of this street
improvement project.
Q14:
I live on Galena Avenue, and every year in the fall, leaves plug the existing catch basins
contributing to flooding in the roadway. Can the catch basins be replaced so this does not
happen every fall?
A14:
Replacing the catch basins along Galena Avenue will not resolve any of the drainage
issues caused by the leaves. Currently, the City schedules sweeping of the streets every
spring after the snow melts and again in the fall. The City recognizes there is a need to
inspect the area catch basins more frequently to monitor the structures for plugging.
Q15:
I live on Gannon Way, and the drainage from the street is directed to my house. I have
tried drain tile and installing rocks to filter the water. Does the City have any plans to
stub storm sewer near my property to redirect the storm water?
A15:
The purpose of this neighborhood meeting is to gather feedback from the residents
regarding issues such as this. Your drainage concerns will be investigated as a part of
this street improvement project. There are property maps at either end of the lunch room.
Please indicate on the maps any drainage issues or concerns you may have. Residents are
also encouraged to fill out a comment card with specific issues they would like to see
addressed with the project. All comments/concerns will be presented to the City Council
at the first City Council meeting in October.

Q16:
Two properties along Gannon Way experience ice build-ups within the street during the
winter months. Does the City have plans to improve the drainage in this area so there are
not patches of ice in the winter?
A16:
All drainage concerns will be investigated as a part of this project. We encourage all
residents to fill out the provided comment cards and include drainage concerns.
Q17:
Does the City work with local utility companies? Is it possible to have all the overhead
utilities buried with this project?
A17:
The City does not determine when or if a private utility is to be buried within a project
area. The City will make every effort to coordinate with the private utility companies to
have the lines buried if the utility company decides to eliminate overhead lines. All
private utilities in the area are contacted and made aware of the project so if there are
plans to relocate or bury utilities, the utility work can be completed concurrently with the
street reconstruction project.
Q18:
What is the design life of a new or reconstructed road?
A18:
Roadways are designed for a 50-year life span. Maintenance activities, such as a mill and
overlay, crack sealing, or chip seal, will be necessary during the lifetime of the new road,
but the new roadways will be designed to last 50-years before another reconstruction
project is necessary.
Q19:
What is necessary for reclaiming the roadway? How much of the road is to be removed?
A19:
Soil borings will be completed throughout the project area prior to construction to
determine the removal limits. If the sub-grade material is acceptable, the road will be
reclaimed and mixed with the existing aggregate base. Additional sub-grade corrections
may be required if the soil borings indicate unsuitable sub-grade materials are present.
Q20:
Is there a specification for manhole casting elevations? Will existing castings be adjusted
to the new road elevation?
A20:
Yes. All castings are required to be depressed 5/100’ (1/2”).
Q21:
Has the City investigated the impacts de-icing chemicals have on roads?
A21:
There has been no conclusive evidence indicating that de-icing chemicals lead to
premature aging of the bituminous surface. However, studies have indicated that as the
de-icing chemical enters the cracks within the roadway and penetrates the sub-grade
material, the chemicals attract the fines within the underlying soils, making the road
somewhat unstable. The de-icing chemicals have been linked to heaving/tenting issues
along some roadways. Over the last three years, the City has proactively reduced the
amount of de-icing chemicals used during snow events.
Q22:
What are the construction hours of operation?
A22:
The City of Lakeville identifies working hours as Monday through Friday, 7:00 AM to
8:00 PM; and Saturday, with permission, from 8:00 AM to 5:00 PM. No work may be
performed on Sundays or Holidays. Working hours observed on the 2011 project were
typically between 7:00 AM and 8:00 PM, Monday through Thursday, 1/2 days on
Fridays, and minimal work on Saturdays.

Q23:
Is the City considering improvements to the bridge and runoff to the creek on Foliage?
A23:
Independent from the street reconstruction project, the City is also studying drainage
through the area commonly referred to as North Creek. Coordination with other
regulatory agencies will be required to complete any such improvements, and the City
will work to coordinate any such activities with the improvements proposed with the
2012 Street Reconstruction Project.
Q24:
How are the assessments determined?
A24:
Assessments are calculated on a per single family unit basis using the construction
contract bid amount. The public hearing to adopt the assessments will be held prior to
construction. Holding the public hearing prior to construction will require that the City
bear the responsibility of any additional unexpected costs encountered with construction.
Q25:
How does the City determine when to apply chip sealant to the streets?
A25:
Previously, the City applied multiple applications of chip sealant to the streets on a 7-year
maintenance cycle. The City’s current pavement management plan dictates that streets
be crack sealed every 2 to 4 years, and that chip seals are now only applied once,
approximately 4-to-6 years after a roadway resurfacing project. Recent research indicates
that multiple chip seals can lead to delaminating issues when the sealant does not bond
100% with the existing road surface, allowing water to enter the pavement.
Q26:
In areas where the sidewalk has heaved due to the root system of the adjacent boulevard
trees, will the trees be removed? Will the City replace these trees?
A26:
The status of each tree will be reviewed on a case-by-case basis. The City Forester will
assist in determining which trees will likely not survive root cutting activities, and
designate those trees for removal. Like many cities, the City of Lakeville does not
replace trees removed within the City right-of-way.
Q27:
What is the standard street section?
A27:
The design for residential streets is 1 ½” of bituminous wear course, 2” of bituminous
base course, 6” of aggregate base, and 12” of approved sub-grade. Streets identified as
collector roadways, such as Foliage Avenue and Gerdine Path, will receive 2” of
bituminous wearing course. The additional bituminous is proposed to accommodate the
higher rates traffic volumes along those collector roadways.
Q28:
What is WSB?
A28:
WSB & Associates, Inc. is a consulting engineering firm.WSB & Associates, Inc. is
working with the City to provide preliminary research, design and construction
observation for the project.
Q29:
Has the City considered installing a round-about at the intersection of Flagstaff and
Dodd?
A29:
The intersection is a County roadway, and therefore, any improvements proposed along
Dodd Boulevard are under the jurisdiction of Dakota County. However, there are no
improvements proposed at that intersection in the County’s current Capital Improvement
Plan.

Q30:
If a repair is identified adjacent to/within my driveway, is there an additional assessment?
A30:
No. Individual property owners will not be assessed for repairs to driveways due to
deficient curb and gutter.
Q31:
How will the construction be scheduled? Will the roads by reconstructing all at once?
A31:
The City will likely phase the construction within the project area. Historically, the City
has specified that construction along any street that is reclaimed must be completed
within three weeks of roadway reclamation. However, in areas where additional utility
improvements will be proposed, construction will likely be limited to six weeks. To
eliminate damage to reconstructed areas, the phasing plan will aim to avoid sending
heavy truck traffic to newly reconstructed areas.
Q32:
Can the turn lane arrows be set back further than their current location?
A32:
All proposed striping will be designed to meet current City standards and specifications.
Q33:
Does the City plan to replace the water main along Gerdine Path?
A33:
Utility maintenance records have identified a number of water main breaks in the area.
Additional testing of the utilities in the area will be completed in the upcoming weeks,
the results of which will be used to determine the limits of any proposed utility
improvements.
