The streets proposed for rehabilitation were chosen using the City's Pavement Management
Program and on -site observation. The streets in Greenwood Shores are 37 years old. The streets
within the project area were last sealcoated in 1992 and 1997. Redman Lane and Shawnee Lane
had a thin overlay paved by public works department staff in 2000 to keep the street from
completely deteriorating. The street conditions in this area were last surveyed in 2010. The
Pavement Condition Indices (PCIs) from the survey are shown on the map below. A PCI below 45
typically warrants reconstruction; however, the utilities in the area are in fair condition and
therefore staff is recommending a full depth mill and overlay of the streets at this time. Subgrade
corrections would be done as needed.

The streets in this area are rural
section and do not have concrete
curb and gutter. The runoff of
this area is not treated in storm
water ponds. Staff has looked at
options to construct ponds in
this area to treat the water, but
no land exists that would be
able to accommodate a pond.
The right -of -way is 50' wide
and therefore there is minimal
space to provide storm water
treatment and rate control along
the roadways. Since no space
has been identified to treat
runoff with traditional means,
staff is recommending not
adding concrete curb and gutter
in this area and allowing the
drainage to route through the
neighborhood as it currently
does today. Environmental
manholes are proposed to be
added at low points in the
development prior to
discharging into the lake or
wetlands to help with water
quality.
I A survey of the existing storm
sewer is being completed. Staff will analyze the information to provide the recommended scope of
storm sewer improvements for the project area. It is anticipated some replacement and additional
storm sewer pipe will be necessary. Also, some draintile is anticipated to be added with the project.

Staff has televised the sanitary sewer system in this area. The system is in fair condition with only
minor repairs identified at this time. The repairs are recommended for inflow and infiltration
issues.
The watermain in this area is ductile iron. City records do not show any watermain breaks in this
area; however, it is recommended to replace the bolts on the valves and some hydrants at this time.
The type of hydrants in the area are not easy to maintain and can cause operational problems.
Typically, gate valve bolts that are in the ground and exposed to soils for this length of time have a
tendency to corrode and break.
Budgets for the proposed work were included in the proposed 2013 CIP. The budgets will be
reviewed and updated based upon current construction cost estimates.
Assessments will be based on the city's practice of assessing 40% of the street improvements to the
benefiting properties on a per lot basis. The assessments would be proposed for 8 years at 6%
interest. Utility improvements would be paid for with the associated enterprise fund.
As with all improvement projects, the Engineering Department will hold several neighborhood
meetings to answer resident questions about the proposed improvements and assessments. These
meetings also give staff an opportunity to gather additional information about the area to help make
the project successful.
City staff proposes to provide the engineering services needed for this project, including feasibility
report preparation, final design and construction administrative services.

FUTURE STREET IMPROVEMENT PROJECTS
The map attached to the report shows the location of the proposed 2013 to 2017 Street Capital
Improvement Project areas. Currently, the average street system PCI is 70, which indicates the
street network overall is in good condition. However, the pavement management software
estimates the average network PCI in 2017 will be below 60 given the current funding levels. This
estimated decrease is due to numerous streets or neighborhoods built in relatively the same time
frame needing improvements at the same time. These areas are older neighborhoods and using
preventative maintenance such as sealcoating is not cost effective because of the condition of the
streets. Staff has identified streets which are not in the next five year's capital plan that are in need
of improvements now. The estimated cost for these improvements is $1.8 million. Staff plans to
discuss this proposal in greater detail at the Council work session.
The Parks Department has plans for making improvements along the south side of Rice Marsh
Lake. The City of Eden Prairie recently completed a trail extension from Dell Road to
Chanhassen's eastern border. This new trail extension also crosses TH 212 at an underpass and
extends to Lyman Boulevard. If the south section of the Rice Marsh trail is constructed, a trail loop
would be completed around Rice Marsh Lake. Also Chanhassen's eastern trail network would have
another connection to the regional trail system. The preliminary estimate for this trail section is
$200,000.
Staff will be discussing funding options for these improvements at the work session.

Total Project Cost: $12,450,000
Annual project to rehabilitate and reconstruct streets in the City. Current 5 -year plan shows the following neighborhood areas:
2013 - Greenwood Shores
2014 - Dartmouth Drive, Cypress Drive and Kiowa Trail
2015 - Carver Beach area (south and west of Carver Beach Road)
2016 - North Manor Road, Washta Bay Road, Tanagers Lane, Sandpiper Trail, Piper Ridge Lane and Minnewashia Woods Drive
2017 - Flaminao Drive area and 96th Street
Justification
The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the
life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
Rehabilitation projects extend the life of the street. In cases with utility or poor sub grade needs to be replaced or where streets have deteriorated
to a point where rehabilitation will no longer be practical reconstruction of the street is necessary. A feasibility study is written to consider the
merits of the project and scope of work.

Description Total Project Cost: $975,000
This annual project includes televising, repairs and rehabilitation of existing sanitary sewer. The program also detects and eliminates points of
entry of ground water and surface water into the City sanitary sewer system. Projects have been identified from the 2006 Inflow and Infiltration
Report. The projects were reviewed by Metropolitan Council and approved in lieu of surcharge fees.
Justification I
City staff has identified numerous older sewer lines that are in need of repair. The City of Chanhassen pays the Metropolitan Council for sewage
treatment. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its
way into the system either through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to
the City for sewage disposal and increasing the load on the City's lift stations.

Budget Impact/Other-
ine errorts may - decrease operational costs, MCES fees and emergency call outs. It is also the City's intent to use connection charges to help fund
for those costs. It is the City's belief that as new customers come on line those connection fees should help fund future infiltration problems.
