Timber Laue Water Mai" Project
City Project No. 04-
WSB Project No. 1074-88
1. EXECUTIVES~Y
City Project No. 04- provides for the extl1Usion ofinunicipal water service to initially serve
the eight of the existing single residences locat~d along Lake MiImetonka on Timber Lane.
To achieve the most advantageous option for tbJe City, two waterline options and two pavement .
restoration options were explored .
Construction of the water main from the end e~isting water main at Timber Lane and Lawtonka
Drive to the end of Timber Lane and the repair I and overlay of Timber Lane is recommended. If
the City has adequate funding, some considera~ons should be given to complete reconstruction
pfTimber Lane. This will provide the long teiin objectives of the project and provided for the
restoration of the pavement. i
The total estimated project cost is $183,026 w~ich includes a 10% contingency and 30% indirect
costs. Funding for the proj ect will consist of special assessments and 2004 Capital Improvement
Plan (ClP) funds. The assessment hearing will be held in the fall of 2004.
!
The proposed assessment rate is $10,000 per l~t. This will generate approximately $80,000 or
approximately 44% of the total project costs. I .
It is proposed that construction would take pl*e in 2004. Construction will: be completed,
including all restoration items in 2004. I
This project is feasible, necessary, and cost effective from an engineering standpoint and should
be constructed as proposed herein.

2. INTRODUCTION
2.1 Author~ation
On February 23, 2004, the Shorewood City Council authorized the preparation of an engineering'
Feasibility Report for the Timber Lane Watermain Project. This project has been designated as
City Project No. 04-
2.2 Scope
The proposed project primarily provides domestic water service for single family residential lots
on Timber Lane. No criterion was given for fire protection. Hydraulic modeling of the City of
~horewood's water distribution system is not a part of this report. .
The Timber Lane environment leaves little choice but to construct the water main within the
existing pavement. As a.result, the pavement will need some restoration as a part of this project.

3. GENERALBACKGROUND
3.1 Project Location
The project is located on Timber Lane in the northeast p~rtion of the City of Shorewood.
The project area is identified on Figure 1 in Appendix A of this report.
3.2 Project Zoning
Generally, the project area is zoned residential.
3.3 Project History
This project was initiated through a petition from the residents currently living on Timber Lane.
Currently, only one parcel is connected to municipal water service, this parcel located at the
westerly end of the Timber Lane cul-de-sac. Many years ago the owner of this property obtained
permission to connect to the City of Tonka Bay's water system.
3.4 Existing Conditions
3.4.1 Streets
Timber Lane is an older roadway of varying paved widths. The pavement varies
from approximately 18 feet wide to 22 feet wide. No curb and gutter exists on the
portion of Timber Lane under review. The general condition of the pavement is
deteriorated, indicating moisture infiltration and poor sub grade soils. There is
visual evidence of lake shore erosion attacking a short stretch of the roadbed.
Portions of the pavement may not necessarily be within the existing right-of-way.
Right-of-way widths vary from 30 feet to 60 feet. .
3.4.2 Sanitary Sewer
The existing sanitary sewers within the project area consist of a 30-inch RCP
trunk sanitary sewer line and a 9". diameter PVC sewer line.
3.4.3 Watermain
Currently, no watermain exists within the project area.
3.4.4 Storm Sewer
All surface water runoff is collected using a system of roadside ditches. Water
collected in the ditch along the south side of the road is conveyed to Lake

4. PROPOSED IMPROVEMENTS
4.1 Watermain
The proposed water main is intended to serve those residential properties that petitioned for the
improvement. Study ofthe water distribution system indicates two possible water main routes to
accomplish this objective.
Watermain Alternate 1: Install the proposed water main entirely within the roadway of Timber
Lane. The water main would run between the intersection ofLawtonka Drive and Timber Lane
and the cul-de-sac at the extreme northwest end of Timber Lane. The water main improvement
consists of approximately 1,560 lineal feet of 8:-inch ductile iron water main, four fire hydrants .
and ten residential service lines. These improvements will provide for the delivery of potable
water to the homes and enhance their fire protection. .
Watermain Alternate 2: Install the proposed water main from the Lawtonka Drive cul-de-sac,
across private property to Timber Lane, then, within the Timber Lane roadway to the cul-de-sac
at the extreme northwest end of Timber Lane. The water niain improvements consist of
approximately 1,050 lineal feet ofS-inch ductile iron water main, three fire hydrants and nine
residential service lines. These improvements will provide for the delivery of potable water to
the homes and enhance their fire protection.
Both alternatives will meet the requirements of the scope of this project.
The proposed water main routings are shown on Figure 2 in Appendix A.
4.1.1 Redundant Water Connections (looping)
Strong consideration should be given to creation of a continuous water
distribution system and the elimination of dead end water mains. Of particular
concern are long dead-end water mains that serve only a few residential
customers. Generally these water mains are sized to provide minimum fire
protection but are too large to be adequately flushed for typical domestic use.
The existing water main on Timber Lane and Lawtonka Drive is an example of a
dead end water main. The extension of this main will exacerbate the problems
associated with dead ends. Considering the farthest northwest residence on
Timber Lane (5425, Kramer) has domestic water provided by the City of Tonk a
Bay, suggests that Tonka Bay has a dead end water main in the vicinity. All
indications are that both communities are in a similar situation; a dead end water
main at or near the corporation line. The proposed water main extension
described in this report provides an opportunity to eliminate a potential dead end
water main for both communities. The exact location ofthe water main that
City of S/Jorewood - Feasibility Report
Timber Lane Water Main Project
City Project No. 04-
WSB Project No. 1074-88
Page S
serves 5425 Timber Lane is not mown, but is assumed to be on Brentwood
Avenue, (City of Tonka Bay) not far from the corPoration line.
A potential solution to be considered is the connection of a water main between
the cities of Tonka Bay and Shorewood near the cul-de-sac of Timber Lane. This
connection is suggested via one of two routes:
Option A would be through permanent easement between the easterly
terminus ofBrentwood Avenue (Tanka Bay) and the northwest comer of
the cul-de-sac of Timber Lane (Shorewood).
Option B would be through an existing un-named public right-of-way
southeasterly from Florence Drive (Tonka Bay) to Timber lane just south
of the cu1~e-sac (Shorewood).
The exact location of the connection would have to be agreed upon by both
communities. If Option A is selected, the effected property owner would have to
be agreeable to executing a permanent easement for the construction of the water
main.
Assuming both communities can agree on a connection of the water distribution
systems at the west end of Timber Lane, there are a number of benefits that could
be realized by both Tonka Bay and Shorewood.
A. Enhanc~d fire flow in the case of a fire demand; water can potentially be
drawn for two sources at the same time to fight a fire
B. Reliability; .
1. two sources are available in the event that one source is damaged
or interrupted for any reason
2. if a portion of the water main is taken out of service, fewer
customers will be effected
C. Improved or more consistent water quality; water having the ability to
flow in two directions is less likely to become stagnate then water at the
end of a water main. Dead ends water mains have a tendency to have
rusty water with low chlorine residuals.
Connection of the City of Tonka Bay water distribution system and the City of
Shorewood water distribution system would provide a benefit to both
communities. .
Each system operator can control activity of the connection with a valve, one
installed for each community near the corporation line.
Potential disadvantages of a connection between the two water. systems are:
City of ShorellJood - Feasibility Report
Timber Laue Water Main Project
CitJl Project No. 04-
WSB Project No. 1074-88
Page 6
A. Unequal pressure between the two systems could cause one system to
drive or flow unrestricted into the" adjoining system. This can be
addressed with a pressure reducing, pressure sustaining valve.
Installation of this valve would require a review of both water
distributions.
B. Lack of agreement on operation between the two communities
C. Cost of installing the connection
D. Difficulty with the adjoining property owners regarding easements
E. Billing
4.1.2 Lawtonka Dead End Water Main
The dead end water main on Lawtonka Drive should be eliminated if there is
routing that makes sense for continuous flow through a distribution system.
One obvious solution to eliminate the dead-end is to would be to connect the
end of Lawtonka Drive water main back to Timber Lane. This would only be
beneficial if the Timber Lane water main did not dead end. One route to
consider is between units 10 and 11 at the west end of Lawtonka Drive.
The issue of redundant waterlines will have little effect on the cost and design
of this project. The final design will include points to connect redundant
water mains to the proposed water main along Timber Lane. .
The proposed water main redundant connection points are shown on Figure 3
in Appendix A.
4.2 Roadway
The rehabilitation of the existing street is intended to" improve the design strength of the
pavement system and provide a smooth street surface with an extended life for the City of
Shorewood and for the local residents. The existing street width and character will be
maintained, as much as possible to minimize the impacts on the existing driveways, boulevards,
and landscaping.
The installation of any underground improvement on Timber Lane is a critical factor in
triggering rehabilitation of the existing pavement. Construction traffic (heavy equipment and
loaded dump trucks) generally causes distressed pavements to deteriorate at an accelerated rate.
Installation of a wa,ter main in the pavement or along the edge of the pavement will require the
pavement to be rehabilitated in some form or other.
As a part ofthe water main installation, two methods of rehabilitating the pavement will be
explored. Generally, the best long term method to strengthen this type of a street is to construct a
pavement section based on accepted practices and engineering judgment. This approach
generally requires removal of the existing pavement and building a more substantial pavement.
If available funds were not an issue, this is the only method that would be investigated. This
City ofSlrorewood - Feasibility Report
Timber Lalle Water Main Project
City Project No. 04-
WSB Project No. 1074-88
Page 7
type of construction may not fit" into the City's short teIm budget constraints, for that reason a
bituminous overlay will be investigated as an alternative. . .
Specifically, the two alternatives prop.osed to rehabilitate the pavement are:
A. The reconstruct the pavement, consisting of two 2-inch layers of bituminous pavement, 6-
inches of Class 5 aggregate base and up to three feet of select granular material as needed
to replace any poor sub grade soils.
B. Overlay the existing pavement with a 2-inch surface course of bituminous pavement.
Patch the trench with four to six inches (flush with the existing surface) of a bituminous
pavement. . .
The proposed roadway sections are shown as Figures 4A and 4B in Appendix A.
4.3 Right-of-Way I Easements
Portions of the existing pavement may be out of or built up to the right-of-way line'ofTimber
Lane. Generally the corporation stops (shut offvalv~) for the water services are place outside
the pavement, at or near the right-of-way line. In this case some corporation stops may have to
be outside the right-of-way to get them a reasonable distance away from the edge of the
pavement.
For work outside the right-of-way it is necessary that a Waiver of Trespass I Right of Entry be
executed by each affected property owner. Realignment of the pavement is not within the scope
ofthis project.
Should Watermain Option 2 (paragraph 4.1 and Figure 2) be selected, permanent easements are
necessary from Gideon Cove (Lawtonka Drive) and the Hennepin County Regional Railroad
Authority (HCRRA).
The HCRRA has ownership of a former railroad bed that crosses the project site. Verbal
indications are that ease~ents are not necessary for work confined within the existing right-of-
way of Timber L~e.
Three Rivers Park District operates a trail for non-motorized use on HCRRA lands. The park
district has requested appropriate signage to warn trail users of construction on the days the trail
will be affected.
4.4 Permits I Approvals
The following peImits will be necessary as part of this project.
Minnesota Department of Health permit for the watermain construction
NPDES permit

4.5 Construction Traffic
This project will require significant excavation and disposal of unsuitable material from the
existing street area and a supply of significant volumes of granular base, aggregate base, and
bituminous pavement materials. This effort will increase loaded truck traffic on the streets
adjacent to the construction area. All residents will have access during construction, however.
some inconvenience is expected. Construction will be phased to minimize inconveniences to the
residents.

5. FINANCING
5.1 Opinion of Cost
Detailed opinions of cost can be found in AppendL-c B of this report. The opinions incorporate
estimated 2004 construction costs and include a 10% contingency factor and all related
administrative costs. The administrative costs are estimated at 30% and include legal, .
engineering, financing, and other administrative items. The cost does not include any easement
acquisition costs.
There are two primary watermain alternatives with three looping sub-alternatives for the
watermain portion, and two street alternatives as follows:
Watermain Alternative No.1 $ 95,481
Consists of approximately 'of approximately 1,560 feet of 8-inch ductile iron water main, copper
service lines for ten single family residential lots and four fire hydrants; follows the Timber Lane
pavement its entire length;
Watermain Alternated No.2 $ 92,035
Consists of approximately 1,050 feet of 8-inch ductile iron water main, copper service lines for
nine single family residential lots and three fire hydrants; runs across private property from the
Lawtonka Drive cul-de-sac to Timber Lane, then along the len~ of Timber Lane.
Watermain Looping Options: these options do not including installation of a watermain to
eliminate the dead-ends, only provide for a point of connection in the future
A. Timber Lane dead-end connection to Brentwood Ave:
Appropriate fittings will be provided in the fmal design for a potential connection to
Brentwood Avenue, if this looping option and location are selected. The cost to provide
the necessary fittings and valves is included in Watermam Alternative No.1 and No.2.
B. Timber Lane dead-end connection to Florence Drive:
Appropriate fittings will be provided in the fmal design for a potential connection to
Florence Drive, if this looping option and location are selected. The cost to provide the
necessary fittings and valves is included in Watermain Alternative No.1 and No.2.
C. Lawtonka Drive dead-end connection to Timber Lane:
Appropriate fittings will be provided in the final design for a potential connection
between Lawtonka Drive to Timber Lane, if Watermain Alternative No.1 is selected.
The cost to provide the necessary fittings and valves are included in watermain
Alternative No.1.

6. FUNDING
Funding for the project will consist of a combination of Special Assessments, Street ClP funds,
Storm Sewer funds.
The proposed Timber Lane Watermain Project w~ initiated by local residents'submitting a
petition for the extension of municipal water service. The existing road surface will also need to
be rehabilitated due the deteriorated pavement condition and the construction of the watermain
with in the roadway; therefore, it is proposed that all costs associated with the extension of water
main and the pavement surface be funded by way of special assessment to the benefiting
properties.
T1:ze selection of Watermain Altern.ative No.1 will provide the benefit of the project to an owner
that did not petition for the improvement. It is suggested that this owner be included in the
assessment if Watermain Alternative 1 is selected.
Nam~: Bagdons
Address: 5585 Timber Lane
Situation: Currently this properly with very limited frontage, if any, along the existing water
main that serves Lawtonka Drive. The construction of the proposed waterline will provide the
benefit of the water main to this properly owner without having to pay an assessment. It is
suggested that this property be participate financially in this project.
It has been determined that each benefi~ing property will be assessed approximately $10,000
totaling $80,000 which is approximately 44% of the total project cost. This is based on $10,000
per lot, per the City of Shorewood's current ordinance. . .
The proposed parcels to be assessed are shown as Figures 5 in Appendix A.
The existing pavement is severely deteriorated indicating poor sub grade soils. It is proposed that
any costs associated with sub grade correction will be funded by the City's Street Capital
development fund.
The City's Storm Sewer Core Fund and Utility Fund are available to fund any storm sewer
improvements. It is proposed that all storm sewer improvements associated with the Timber
Lane Watermain Project be funded by the City's Storm Sewer Core Fund and Utility Fund.

7. FEASIBILITY AND RECOMMENDATION
A. Watermain
Watermain Alternative No.1 is recommended; it provides for the domestic water service
as petitioned, provides for fite protection and provides for future redundant watennain
connections in the future. Watermain Alternate No.2 provides the same benefit, but does
not provide a significant cost savings to justify the need for easements, difficult
construction and potential disruption caused by construction and the potential difficulty
for futUre maintenance.
B. Roadway
Street Alternate No.2 is recommended due to funding concerns. If the City has adequate
funding, it is strongly recommended that the reconstruction alternate be considered.
C. Rec;lund8.nt Watennain Connections
Lawtonka Drive dead-end connection to Timber Lane is recommended in the future to
alleviate fufure water quality issues that may develop. This work may be done anytime
funding and demand creates the necessity.
Timber Lane dead-end connection to Florence Drive is recommended in the future to
alleviate future water quality issues that may develop. This work may be done anytime
funding and demand creates the necessity.
A summary of the proposed funding for the recomn;tended improvements, excluding the future
redundant looping improvements is as follows:
