1. OVERVIEW:
Agenda 2ANumber:
To: Laurie Ahrens, City Manager
Prepared by: Dave Callister, Administrative Services Director
Item: Major Street Funding Options
In addition to the City's Street Reconstruction Program, there are two major street projects
that have been identified in the City's Capital Improvement Program (CIP) to be undertaken
in the next few years. The projects include:
Peony Lane Project - estimated cost of $11.3 million
Vicksburg Lane Project - estimated cost of $19.4 million
In order to determine the financial feasibility of when the projects are undertaken, it is
important to first review all potential sources of funding.
2. FINANCING OPTIONS:
Potential financing sources include:
Municipal State Aid (MSA)
Current MSA rules allow MSA cities to request advancements of up to the lesser of $4
million dollars or five (5) times their annual allotment to fund construction of state aid
roadways. The advancement would be repaid by the City's future allocation of state aid
funds. The City's current rate of allocation is approximately $2 million annually.
Federal Funding
Special Assessments- the report assumes that a residential property would be assessed
based on a 32 foot wide roadway.
Bonds — issued for a 15 year term at 3%
Area Charges (See below)
Franchise Fees (See attachment)
Utility Trunk Fund

3. PROJECTS:
Peony Lane
The funding for Peony Lane is currently not designated in the Capital Improvement
Program. Although the exact funding source is unknown it will likely come from a variety
of sources. A funding mix of special assessments and MSA funds is assumed to finance the
street improvements.
Area Charges
Another option for funding a portion of the Peony Lane street improvements that the City
Council may wish to consider is establishing, by ordinance, a development fee similar to
Park Dedication that would be dedicated to fund Peony Lane. This fee would only apply to
developing properties in the Northwest Area.
Two methods were analyzed by city staff to determine the most appropriate means by
which to establish the fee.
The first method analyzed was determining the trips that are expected to be generated by
the development of the property in the Northwest Area in the vicinity of Peony Lane using
population and employment data from the City's Land Use Plan element of the 2030
Comprehensive Plan. The number of trips generated utilizing this method was 17,585
additional trips from 2005 data to projections in 2030.
The second method analyzed was determining the trips expected to be distributed onto the
roadway system by development of the property in the Northwest Area in the vicinity of
Peony Lane using the City's Transportation Plan element of the 2030 Comprehensive Plan.
The number of trips generated utilizing this method was 17,510 additional trips from 2005
data to projections in 2030. Since the two methods yielded very similar results in terms of
expected traffic volumes generated by development of the Northwest Area, the
Transportation Plan Element method was utilized to establish the percentage of trips on
Peony Lane generated by development of the Northwest Area. This percentage was then
used to calculate a fee based and equivalent percentage of the cost divided into the potential
number of units to be developed, which was extracted from the net area of land in the
Northwest Area of 1,104.09 net acres. The assessment per unit was calculated as follows:
Total Construction Cost (less R/W) $8,991,400
Attributable to Development (49%) 4,405,786
Northwest Area Size (Net Acres) 1,104.09
Cost Per Acre $3,991
Assuming an average of four units per acre within the study area equates to a cost per unit
of roughly $1,000 per unit. There is an expected increase in the number of households in
the Northwest Area from 2005 to 2030 of 1,813 households. The total assessed would be
1,813,000 or a total of 20% of the construction cost.
Vicksburg Lane
Currently the CIP outlines funding sources for Vicksburg Lane as federal funding and
MSA. Although not identified currently, special assessments may be considered for a
portion of the funding needs but they may not significant.

4. IMPACT OF G.O. BONDS:
Peony Lane
Estimated Project Cost $11,300,000
Less MSA 825,000
Net local share $10,175,000
G.O. Bonds (15 years @ 3%)
Annual Principal & Interest $ 852,325
Increase in city levy due to Peony Bonds = 2.9%
Vicksburg Lane
Since federal funding for Vicksburg Lane is far from certain we have not assumed that any
will be available for this project. In addition, MSA funds may be available if not used for
Peony Lane or other projects so we have not included MSA in the tax impacts.
Estimated Project Cost $19,400,000
Less Other Revenue 0
Net local share $19,400,000
G.O. Bonds (15 years @ 3%)
Annual Principal & Interest $ 1,706,325
Increase in city levy due to Vicksburg Bonds = 5.8%
The MSA funding allocated to the Peony Lane project represents approximately three years
of our total annual funding which means that there would be no MSA available for other
projects during this time.
It is likely that both bonds would not be issued at the same time. In addition, the City is
anticipating the issuance of G.O. Open Space Bonds in 2013/2014 which will add annual
debt payments of approximately $290,000, a .32% tax levy increase.
The following is a summary of future tax impacts for bonded debt as outlined above.
Levy increase is calculated from 2013 preliminary levy.

Franchise Fees
Minnesota law authorizes municipalities to impose franchise fees for utilities that use the public
right-of-way or other public property. The fees may be collected to defray the costs to the city of
the utility company's use of the right-of-way or may be used for general revenue purposes. Fees
are then charged to all utility customers regardless of the type or use of property. Churches,
schools and other tax exempt properties would pay franchise fees. The franchise fees are billed
by the provider directly to the customer and itemized on their bill as a city fee. The utility then
collects the fees and passes the revenue on to the city.
For simplicity and funding stability, most cities have a flat fee per meter but others charge a fee
based on a percentage of the total bill. Funds may be designated for a specific purpose or can be
used as a general revenue.
City of Minnetonka — In 2005, adopted electric franchise fee only. In 2007, fee was increased
to $2.50 per month per residential connection. Annual revenue of $800,000 dedicated to burial
of overhead utility lines and above ground decorative lighting.
City of St. Louis Park — Currently has both electric and gas franchise fees and charges $2 each
per month per residential connection. Annual revenue of $910,000 is dedicated to street
rehabilitation (Pavement Management Fund).
City of Eden Prairie — Adopted franchise fees for gas and electric in June of 2012 at $2.50 each
per month per residential connection. Annual revenue of $2 million will be used for long term
street maintenance.
City of Edina — On August 6, 2012, the Council unanimously approved the first reading of the
ordinance implementing gas and electric franchise fees at $1.45 each or a total of $2.90 per
month per residential connection. If adopted, the annual revenue is estimated at $1.1 million will
be used to fund new improvements such as sidewalks, trails and non -motorized transportation
prof ects.
City of Golden Valley — Implemented electric franchise fee at $2 per month per residential
connection. Annual revenue of $600,000 dedicated for Douglas Drive improvements
undergrounding).
City of Hopkins — Electric and gas franchise fees at $1.70 per month each per residential
connection. Annual revenue of $490,000 used to offset the loss in state aid programs.
City of Plymouth — Currently no franchise fees. If monthly fees were adopted at $2 per utility
per residential connection, it would generate an estimated $1.32 million annually.
All of the cities included above have higher rates for commercial users based on the type of user
such as:
1) small commercial with non -demand
2) small commercial/industrial with demand
3) large commercial/industrial user

Intrnrli irtinn
The Northwest Area of the City remains the largest area of principally undeveloped residential
guided land. The majority of the anticipated housing growth in the coming years will occur in
this corner of Plymouth. This study was undertaken to determine what properties within the area
currently have access to trunk sanitary sewer, watermain, and paved streets within an acceptable
distance and what extensions are necessary to provide City infrastructure in an appropriately
phased manner to the remainder of the area.
The study area boundary is shown on the attached exhibits, but in general consists of the area
west of Dunkirk Lane and north of the railroad tracks to the City boundary. The area is 1,390
acres in size. The study looks at the means to provide infrastructure in a staged and cost
effective manner to this area that balances development with preserving natural features and
open space. Service is deemed provided if it is located within '/a mile of a parcel.
Existing Conditions
Street Network
The existing street network and the parcels currently served with a paved street are shown on
Exhibit 1. The Northwest Area is currently served with a B -Minor Arterial (County Road 47) on
the north side, an A -Minor Arterial (County Road 101) on the west border and an A -Minor
Arterial (Peony Lane) in the south portion of the area. Local and private roads provide access to
properties within the area. Dunkirk Lane is a gravel road with sections that are proposed to be
paved with future development on the south and north ends of the roadway.
The study area has significant topographic relief and numerous wetlands that require more
analysis for street extensions than flat areas. There are also numerous City owned parcels within
the study area that are part of the proposed Northwest Greenway.
Trunk Sanitary Sewer
The extension of the Elm Creek Interceptor by Metropolitan Council Environmental Services has
provided sewer access to the Northwest Area in general. The location of the Elm Creek
Interceptor is shown on Exhibit 2. The design of the interceptor provides for multiple points of
1
connection for the sub -districts within the area. Exhibit 2 shades properties that currently have
access to sanitary sewer within 1/4 of a mile from their property border. A majority of access is
achieved through proximity to the Elm Creek Interceptor.
There is also lateral sanitary sewer that borders the study area on the southeast side that provides
service. Wayzata High School is served by a sanitary sewer that runs parallel with Peony Lane.
In addition, the properties on the south end of Dunkirk Lane are also shaded as having access on
Exhibit 2 through a lateral sanitary sewer that was extended to the edge of the Timber Creek
Crossing Addition.
Trunk Watermain
The location of existing watermain is isolated to the south and east portions of the study area.
Service to properties shaded on Exhibit 3 is possible from watermain stubs from the Timber
Creek Crossing Addition, Harvest Hills, and Steeple Hill plats. Wayzata High School is served
by watermain that is stubbed on Peony Lane north of Schmidt Lake Road.
Proposed Improvements
Street Network
In order to provide adequate paved street access to the properties within the study area the
following street improvements and extensions were reviewed and are shaded on Exhibit 4:
1. Peony Lane/Lawndale Lane — From just south of 54th Avenue to Lawndale Lane in
Maple Grove
2. 54th Avenue — From Peony Lane to County Road 101
3. Dunkirk Lane — The section outside of the proposed development as shaded
4. East/west Route — From Dunkirk Lane to Peony Lane. This route is labeled as 58th
Avenue for discussion purposes within the remainder of the study.
Peony Lane:
The City has expended considerable effort on the proposed extension of Peony Lane/Lawndale
Lane from south of 54th Avenue to Lawndale Lane at the border with Maple Grove. A public
informational meeting was held in early May 2012. It is anticipated based on the response from
that meeting and information prepared to date by city staff and their consultant that the preferred
alignment as presented at the public information meeting is Alignment 3. The proposed
2
extension of Peony Lane as shown on Exhibit 4 of this report reflects the preferred Alignment 3.
Preliminary cost estimates are based on a four -lane divided roadway.
The extension of Peony Lane provides paved street access to the properties located within the
center of the study area
54th Avenue:
54th Avenue is proposed to be extended from Peony Lane to County Road 101. The roadway
would provide access for the future Speak the Word campus and the properties on the south end
of Vagabond Lane. It would also provide access to the north side of the Elm Creek Golf Course.
The roadway would be extended as a two-lane undivided roadway with 66 -feet of right-of-way.
The roadway width will vary from 32 -feet to 44 -feet. The proposed layout for the future Speak
the Word campus was utilized for the alignment of the roadway adjacent to their property. In
addition, existing wetlands and topography within the proposed corridor have been taken into
account in developing the remainder of the preliminary proposed alignment shown on Exhibit 4.
Number of privately owned impacted parcels (right-of-way) 8
City -owned property impacted (acres) 0
Parcels with structures that require relocation 0
Wetland impact (acres) 0.35
Maximum slope of the proposed street 8%
Crossing of Elm Creek No
There are City owned parcels on the east end of the proposed 54th Avenue alignment that could
be utilized if less acquisition of right-of-way is desired. However, this will impact additional
wetlands. In addition, the proposed alignment takes into consideration the location of the Elm
Creek Interceptor to include the manhole locations within the right-of-way where feasible.
Shifting the roadway onto City property would move the roadway south of the Interceptor.
Dunkirk Lane:
Dunkirk Lane from County Road 47 to the south is also proposed as a two-lane undivided
roadway with right-of-way generally 66 -feet in width and a 32 -foot wide roadway section.
Proposed development layouts have been submitted to the City for the Scherber Partnership
Properties adjacent to Dunkirk Lane just south of County Road 47 and the parcels just north of
the Timber Creek Crossing Addition. Dunkirk Lane would be constructed by the developers
3
within these segments. The preliminary cost estimates are only for the highlighted section of
Dunkirk Lane shown on Exhibit 4. The City did receive $133,000 from a developer towards the
future upgrade of Dunkirk Lane. The roadway would generally be constructed in the location of
the existing gravel road and therefore impacts to properties and wetlands are negligible.
58th Avenue:
Due to minimal east/west routes between Dunkirk Lane N and the proposed extension of Peony
Lane, the area was reviewed to determine if an additional east/west route would be feasible and
cost effective. The highlighted route on Exhibit 4 was identified as the route with the least
wetland impacts. The following is a summary of impacts with the proposed route:
Number of privately owned impacted parcels (right-of-way) 3
City -owned property impacted (acres) 0.4
Parcels with structures that require relocation (garage) 1
Wetland impact (acres) 1.45
Maximum slope of the proposed street 8%
Crossing of Elm Creek Yes
Sanitary sewer is proposed to be extended from Peony Lane across the wetland in the vicinity of
where the street is proposed. If the street is extended watermain should also be extended to
provide for additional looping of the system. The street would allow for access to these utilities
for future maintenance.
There are City owned parcels on the east end of this roadway that could be utilized to minimize
right-of-way acquisition. The roadway was moved to the south of the City owned parcels to
avoid impacts to a house and keep the impacts limited to the garage.
The roadway is not entirely necessary for the street network system due to the proximity to
County Road 47, which is an east/west route approximately 1,350' to the north. However, if an
additional east/west route is desired between County Road 47 and Schmidt Lake Road the
identified location of 58th Avenue is the most logical due to the extent of existing wetlands in the
remaining corridor.
M
Trunk Sanitary Sewer
As noted above, the extension of the Elm Creek Interceptor provided access to sanitary sewer
within 1/4 mile to a number of parcels within the study area. Four main trunk extensions are
proposed to serve the remaining parcels within the area and are shown on Exhibit 5. Exhibits are
also included that provide information on the existing topographic relief of each segment and the
depth of sanitary sewer that would be necessary to service the area. A summary of the
extensions follows:
Segment 1: This segment will serve the parcels located in the northwest corner of the
study area. 85% of the sanitary sewer depth is less than 30 -feet, however
approximately 15% of the sewer is between 30 -feet and 40 -feet in depth.
An optional alignment to serve the parcels north of County Road 47 was reviewed
under Segment 0. Segment 0 would replace the need to construct Segment 1B and
install a crossing under County Road 47; however the length of sanitary sewer to
construct is longer for Segment 0. The sewer depth would all be less than 30 -feet.
The phasing of development in the area may ultimately determine which alignment is
constructed.
Segment 2: This segment would serve the Elm Creek Golf Course. The extension shown
on Exhibit 5 to serve the area north of T.H. 55 and west of Peony Lane in the south
corner of the study area is from the Elm Creek Interceptor. There is existing sanitary
sewer in the southwest corner of the study area near T.H. 55 that could be extended
north to serve this area as well. The Elm Creek Interceptor and the existing sanitary
sewer south of T.H. 55 both have adequate depth to service this area.
Elm Creek cuts through the south portion of the golf course. Given the topographic
relief of the property and the location of Elm Creek the sanitary sewer depth becomes
excessive if an attempt is made to service the entire property from either the Elm
Creek Interceptor or the T.H. 55 sanitary sewer alone. If depth is to be minimized an
extension may be necessary from both directions that terminates on either side of Elm
Creek. If Segment 2 is extended at a depth necessary to service this entire area the
required depth would include approximately 615' of sewer that is 50 to 60 -feet deep.
5
Segment 3: This segment will serve the parcels located on the east side of the study area.
The installation of Segment 3 will require crossing of a wetland and Elm Creek. An
extension through a City owned parcel will provide service to the northeast corner of
the study area. Approximately half of the length of sewer necessary to serve this area
is under 20 -feet in depth and the other half is less than 30 -feet in depth.
Segment 4: This segment is the extension of Segment 1 to serve the area within Phase 4.
Depending on the final alignment of this sanitary sewer main and the timing of the
installation it may be necessary to disturb the north portion of Troy Lane. No costs
have been included for street impacts in the estimated cost section.
A summary of the parcels served, number of developable lots, and length of sewer follows in the
Appendix as Table 1.
Trunk Watermain
The length of watermain necessary to provide service to all parcels within 1/4 mile is greater than
the length of sanitary sewer. The proposed watermain extensions are shown on Exhibit 6. In
general, the mains shown are those necessary to provide service to the properties within the area.
Water modeling was completed for various scenarios to compare potentially long dead-end
segments with looped trunk watermain. Segment A6 and Segment E were added beyond that to
simply serve the properties within the study area as a means to provide redundancy and increased
fire flow. Water modeling results are shown in Appendix C. Each phase is discussed in greater
detail below.
Segment A: This segment will extend watermain along the proposed Peony Lane
extension. This will provide the main trunk extension to the properties located in the
northwest corner of the study area. An alternate alignment for a portion of the
watermain along Peony Lane has been included. This alternate assumes that
watermain would be extended utilizing a future development to the west of Peony
Lane when possible. The purpose would be to reduce the cost to the City by paying
for the upsizing of watermain installed within the development from lateral to trunk
rather than incurring the cost of paying for the entire trunk main.
Water modeling was completed to determine if a watermain loop was necessary along
County Road 47 to loop the Peony Lane trunk main into the trunk main that currently
2
terminates at County Road 47. Available fire flow and peak hour pressure for the
surrounding area was determined for a dead end main on Peony Lane and a looped
system. For residential properties the required fire flow is 1,500 gallons per minute
for two hours with a minimum residual pressure of 20 psi.
Comparing the results of the two scenarios indicates that minimal variations will be
observed in pressure. Variations under 10 psi will be negligible to most customers.
In addition, the required fire flows are met in both cases. The trunk watermain
Segment A6 is proposed to be constructed in the first phase to provide reductions in
service disruptions and to provide a level of redundancy to the system in case of main
breaks or other emergencies such as fire suppression operations.
Segment B: This segment extends watermain from Peony Lane along the future 54th
Avenue extension to serve the southwest portion of the study area. Depending on the
timing of the construction of
54th Avenue it may be possible to install the watermain
ahead of any street construction by utilizing the easement obtained for the Elm Creek
Interceptor.
Segment C: This segment extends watermain along Dunkirk Lane to serve the east
portion of the study area. Watermain would be extended from the proposed
developments adjacent to Dunkirk Lane.
Segment D: This segment is the extension of Segment A to serve the very northwest
corner. Installation of the watermain along Troy Lane could be accomplished with
minimal street impacts with installation by directional bore.
Segment E: This segment is to provide looped watermain from Segment B to Segment
D. The 2030 Comprehensive Plan currently calls for Commercial, C, in the very
northwest corner of the study area and Semi-Public/Institutional, P-1, along the west
edge adjacent to County Road 101. For commercial, institutional, and industrial land
uses the minimum fire flow is 3,500 gallons per minute. To achieve this required rate
it will be necessary to loop the two segments along County Road 101.
7
If an east/west route from Dunkirk Lane to Peony Lane were constructed in the future then the
City may want to consider the installation of watermain along the route for additional looping
purposes.
Phasing
Phasing of the improvements is an important component of providing service to the Northwest
Area. The goal of the phasing is to outline a logical, controlled development of the Northwest
Area while ensuring an overabundance of lots is not created or that expenditures are not made
before they are needed. The phasing plan that follows is based on the current rate that land is
being consumed for residential development within the City. The City observed a recent rate of
land consumed by development of 185 acres over two years. In addition to acres consumed a
review of the building permits issued over the last three years was also reviewed. The number of
residential permits issued per year is as follows:
Year Number of Building Permits Issued
2009 75
2010 133
2011 288
Total: 496
It was determined that for this report an average consumption rate of 165 lots per year would be
used.
There are currently 910 potential residential lots with access to paved streets, sanitary sewer, and
watermain that are located outside of the study area. Assuming a rate of consumption of 165 lots
per year, the land would be consumed for development within 5 to 6 years.
Four phases are proposed for the extension of streets, sanitary sewer, and watermain to service
all of the properties within the service area. The phases could be further broken down if so
desired.
Phase 1: Peony Lane/Lawndale Lane is proposed for construction in the summer of 2014. The
construction of this roadway and the associated watermain, which consists of the
Segment A sections, is considered to be the first phase of developing the area within
the Northwest Area.
Phase 2: The extension of 54th Avenue and the watermain consisting of the Segment B sections
is proposed for Phase 2. Sketch plans have been prepared for the Speak the Word
campus and the Elm Creek Golf Course; however no final plans have been
completed.
Phase 3: The construction of the remaining portions of Dunkirk Lane N after the development
of the north and south properties within the study area and the watermain segments
consisting of Segment C sections are included in Phase 3. This phase does require the
extension of the sanitary sewer Segment 3 sections. Construction of 58th Avenue or
another east/west route as part of this phase is optional.
Phase 4: Phase 4 consists of the construction of the Segment D and Segment E watermain
sections and Segment 4 of the sanitary sewer sections.
The number of residential lots created with each phase is outlined below:
Phase Number of Lots Time of Build Out ears
1 917 5.5
2 637 3.9
3 319 1.9
4 458 2.8
Total Lots: 2,331
The number of lots created is based on the maximum allowed according to the 2030
Comprehensive Plan and the anticipated zoning for the area. The time to build out is based on
the current consumption rate of an average amount of 165 lots per year.

Estimated Costs
Preliminary construction costs have been calculated for the infrastructure necessary to service the
properties within the Northwest Study Area.
Street Improvements:
Peony Lane /Lawndale Lane Right-of-way $ 2,000,000
Construction $ 9,000,000
Total $11,000,000
54th Avenue Right-of-way $ 525,000
Construction $ 2,775,000
Total $ 3,300,000
Dunkirk Lane Right-of-way $ -
Construction $ 900,000
Total $ 900,000
58th Avenue Right-of-way $ 425,000
Construction $ 1,300,000
Total $ 1,725,000
Assumptions:
1. The estimated costs for Peony Lane/Lawndale Lawn are based on Alignment 3 and
were prepared by WSB & Associates.
2. Right-of-way costs were based on a rate of $2.50 per square foot, which was used for
all parcels. Actual costs will vary depending on the final alignment chosen and
individual impacts to parcels. No costs were included for impacts to City owned
properties.
3. The estimated costs for 54th Avenue are based on a 44 -foot wide roadway and include
a trail or sidewalk. The right-of-way cost could be reduced in City owned property is
utilized for a portion of the alignment.
4. It is assumed that no additional right-of-way will need to be obtained for Dunkirk
Lane and that the improvements will occur within the existing right-of-way. The
existing right-of-way width is a minimum of 66 -feet through the proposed
improvement area. The estimated costs are based on a 32 -foot wide roadway.

Pae 12
5. The estimated costs for 58th Avenue are based on a 32 -foot wide roadway and include
a trail or sidewalk. The right-of-way cost could be reduced in City owned property is
utilized for a greater portion of the alignment.
Trunk Sanitary Sewer
The estimated costs are shown in Table 1 and are based on the sizing shown. Sanitary sewer
costs do not include any cost for easement or right-of-way acquisition. The costs also do not
include major street repairs.
Trunk Watermain
The estimated costs are shown in Table 2 and are based on the sizing shown. Watermain costs
do not include any cost for easement or right-of-way acquisition. The costs also do not include
major street repairs.
Proposed Phase Costs
The cost for each of the four phases is summarized below and includes the street, sanitary sewer,
and/or watermain that would be necessary to provide access to all three components of
infrastructure.
Phase 1 Street $11,000,000
Sanitary Sewer $ 340,000
Watermain $ 1,400,000
Total $12,740,000
This is the cost to provide access to infrastructure within the Phase 1 area and build out of
the Phase 1 area, which includes trunk extensions to serve future phases. As the area
within Phase 1 develops the sanitary sewer Segments 1, IA, and 113 (or Optional 0)
would be installed. The City could work with the developer to have the sanitary sewer
installed at the size and depth necessary to serve the properties to the north and west. In
addition to the sanitary sewer, trunk watermain Segments A4 and A5 would also be
installed as the area develops. If the utilities are extended with development the cost
would be reduced from that noted above.
11
Pae 13
Phase 2 Street $ 3,300,000
Sanitary Sewer $ 195,000
Watermain $ 405,000
Total $ 3,900,000
If the Elm Creek Golf Course develops as one large development, the sanitary sewer
access would be from the Elm Creek Interceptor and the City would not need to incur the
sanitary sewer cost associated with Segment 2. In addition, the watermain costs
associated with Segment B 1 would not need to be incurred.
Phase 3 Street $ 900,000
Sanitary Sewer $ 235,000
Watermain $ 340,000
Total $ 1,475,000
If an east/west roadway is desired between Dunkirk Lane and Peony Lane it could be
constructed as part of this phase to further connect the properties within Phase 3 to the
street network. The alignment of 58th Avenue that is shown on Exhibit 4 is the shortest
route with the least wetland impacts. The cost could change significantly depending on
the final route chosen, but is estimated at $425,000. This cost would be above and
beyond what is shown above. The watermain costs may also be lower as it would be
routed through any potential developments that occur prior to the construction.
Phase 4 Street -
Sanitary Sewer $ 120,000
Watermain $ 565,000
Total $ 685,000
No street improvements have been included as part of this phase. Depending on the
alignment chosen for Segment 4A, impacts to Troy Lane as part of the extension may be
incurred.

Financing
Financing the proposed improvements is proposed to come from a variety of sources.
Streets
Current municipal state aid (MSA) rules allow MSA cities to request advancements of up to the
lesser of $4 million dollars or five (5) times their annual allotment to fund construction of state
aid roadways. The advancement would be repaid by the City's future allocation of state aid
funds. The City's current rate of allocation is approximately $2 million annually.
The other funding source available to the City is special assessments. The report assumes that a
residential property would be assessed based on a 32 -foot wide roadway.
Peony Lane:
The funding for Peony Lane is currently designated as "Other" in the Capital Improvement
Program. Although the exact funding source is unknown it will likely come from a variety of
sources. A funding mix of special assessments and MSA funds is assumed to finance the
roadway improvements.
Another option for funding a portion of the Peony Lane street improvements that the City
Council may wish to consider is establishing, by ordinance, a development fee similar to Park
Dedication that would be dedicated to funding for Peony Lane. This fee would only be
applicable to developing properties in the Northwest Area.
Two methods were analyzed by city staff to determine the most appropriate means by which to
establish the fee. The first method analyzed was determining the trips that are expected to be
generated by the development of the property in the Northwest Area in the vicinity of Peony
Lane using population and employment data from the City's Land Use Plan element of the 2030
Comprehensive Plan. The number of trips generated utilizing this method was 17,585 additional
trips from 2005 data to projected 2030 data.
The second method analyzed was determining the trips expected to be distributed onto the
roadway system by development of the property in the Northwest Area in the vicinity of Peony
Lane using the City's Transportation Plan element of the 2030 Comprehensive Plan. The
number of trips generated utilizing this method was 17,510 additional trips from 2005 data to
projected 2030 data.
Since the two methods yielded very similar results in terms of expected traffic volumes
generated by development of the Northwest Area, the Transportation Plan Element method was
13
utilized to establish the percentage of trips on Peony Lane generated by development of the
Northwest Area.
This percentage was then used to calculate a fee based and equivalent percentage of the cost
divided into the potential number of units to be developed, which was extracted from the net area
of land in the Northwest Area of 1,104.09 net acres.
The assessment per unit was calculated as follows:
Total Construction Cost (less R/W) $8,991,400
Attributable to Development (49%) 4,405,786
Northwest Area Size (Net Acres) 1,104.09
Cost Per Acre $3,991
Assuming an average of four units per acre within the study area equates to a cost per unit of
roughly $1,000 per unit. There is an expected increase in the number of households in the
Northwest Area from 2005 to 2030 of 1,813 households. The total assessed would be
1,813,000 or a total of 20% of the construction cost.
Dunkirk Lane:
Dunkirk Lane is proposed to be funded through special assessments to abutting properties. The
roadway is proposed as a 32 -foot wide street and assessments would be based on this width.
54th Avenue:
54th Avenue is proposed to be funded through special assessments to abutting properties. The
roadway is proposed as a 32 to 44 -foot wide street. A portion of the street abuts property that is
not currently zoned as residential. Assessments to these properties would be based on the full
street width while residential properties would be based on a 32 -foot width. 54th Avenue is also
currently on the City's MSA system. This would allow the use of MSA funds for the
construction of the roadway.

58th Avenue:
58th
Avenue is proposed to be funded through special assessments to abutting properties. The
roadway is proposed as a 32 -foot wide street and assessments would be based on this width.
Sanitary Sewer and Watermain
As identified in the 2030 Comprehensive Plan the City uses two main sources of funding to
finance construction of trunk utilities. They are area charges and connection fees. In addition to
these two sources the City could reduce expenditures or apply a lateral assessment to Developers
or property owners for utility extensions through developments that could be utilized for
individual lot service. The City could require the Developer to oversize and/or have increased
bury depth on mains that could be utilized as both lateral and trunk mains. The City would have
to fund only the additional costs above and beyond a typical 8 -inch main for both the sewer and
watermain.
Using all of these funding mechanisms results in excess funds being generated by the extension
of the proposed segments; however these excess funds would be needed to provide for additional
wastewater treatment capacity and water production, treatment, and storage.
Summary of Financing
The construction cost of each phase is compared to the funding mechanisms that have been
identified for the corresponding improvements.
15
Phase 1 Overall Cost 12,740,000
REC Charges 1,610,000
Area Charges 1,300,000
Lateral by Developers 600,000
Development Fee (Peony) 1,813,000
Municipal State Aid 4,000,000
Street Assessments 3,382,750
Shortage/Excess 35,000 Shortage
Phase 2 Overall Cost 3,900,000
REC Charges 940,000
Area Charges 915,000
Lateral by Developers 145,000
Municipal State Aid
Street Assessments 2,204,000
Shortage/Excess 304,000 Excess Generated
Phase 3 Overall Cost 1,475,000
REC Charges 225,000
Area Charges 455,000
Lateral by Developers 170,000
Street Assessments 1,796,200
Shortage/Excess 1,171,200 Excess Generated
Phase 4 Overall Cost 685,000
REC Charges 615,000
Area Charges 295,000
Lateral by Developers 125,000
Shortage/Excess 350,000 Excess Generated
The overall cost for Phase 3 assumes the construction of 58th Avenue. None of the construction
costs provided above include engineering, administration, and legal expenses. The assessment
numbers generated are based on construction cost and right-of-way. In addition, the street
16
assessment amounts are only dollar amounts received from property owners but are based on a
front footage amount that accounts for the City parcels also being assessed.
Summary
The construction of Peony Lane/Lawndale Lane and the watermain segments contained with
Phase 1 will open up the Northwest Area to the potential for five (5) additional years of
residential development at the current consumption rate. The City could reduce the cost of
extending utilities to areas outside of Phase 1 by requiring that the majority of the trunk utilities
be installed as development occurs and thereby incurring only the oversizing costs. However,
this would result in staged development and properties outside of the logical sequencing would
have greater difficulty in developing outside of the time line driven by this sequencing. This
would also require the City to work with developers to ensure that improvements can serve the
upstream properties in an appropriate manner.
Development pressure from individual properties will most likely drive the final phasing plan
that occurs for the overall area; however the City can anticipate the need to construct 54th
Avenue or upgrade Dunkirk Lane within 5 years of the completion of Peony Lane/Lawndale
Lane.

Notes
1. Number of developable lots is estimated based on maximum density allowed by zoning x developable acres.
2. City Sewer Connection Charge (REC) is based on current rate of $415 per unit.
3. City Sewer Area Charge is based on current rate of $1,024 per developable acre.
4. Lateral construction cost is the cost to install an 8 -inch main through the property for lateral service. The developer would be responsible for this cost.
5. If the developer installs the utility the City would be responsible for the oversizing cost, which is the total segment cost minus the lateral cost.
