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. v m Kerber 14 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. g: \eng \pub1ic \_2013 projects \13 -01 greenwood shores \09 -10 -2012 work session.docx Paul Oehme 2013 Street Improvement Project September 10, 2012 Page 3 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. A tentative schedule is as follows: Authorize Preparation of Feasibility Report October 8, 2012 Neighborhood Meeting November, 2012 Accept Feasibility Report November, 2012 Hold Public Hearing January, 2013 Bid Opening March, 2013 Assessment Hearing April, 2013 Start Construction May, 2013 Substantial Completion September, 2013 Funding for the project will be from several sources as follows: Revolving Assessment Fund $ 950,000 Storm Sewer Utility Fund $ 100,000 Water Utility Fund $ 75,000 Sanitary Sewer Utility Fund $ 60,000 $1,185,000 gAeng \pub1ic \_2013 projects \13 -01 greenwood shores \09 -10 -2012 work session.docx Paul Oehme 2013 Street Improvement Project September 10, 2012 Page 4 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. Attachments: 1. Proposed Local Annual Street Improvement Program Map 2. Preliminary CIP pages 3.

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.

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.

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. 89 City of Chanhassen Proposed Projects if Additional Funding is Granted /S 2013 Mill and Overlay /\/ 2015 Mill and Overlay N 9.0 ,.
