City Council approval requires a simple majority vote of the City Council present." BACKGROUND At the September 10, 2012 work session, staff reviewed with Council the proposed 2013 Street Improvement project areas. Staff also discussed with the Council the need to make improvements to more local streets then are currenity budgeted for in the capital replacment plan. DISCUSSION Every year the City considers streets that are in poor condition to be rehabilitated or reconstructed. For the 2013 Street Improvement Project, staff is proposing to rehabilitate approximately 4.6 miles of streets. The street segments within the proposed project were identified by the City's Pavement Management software in conjunction with site investigations and are shown below.

Severe pavement distresses will be removed and replaced. Minor drainage improvements are also proposed to be addressed in the project areas. Watermain gate valve and hydrant bolt replacements are proposed for replacement in these areas. A feasibility report will be prepared by the Engineering Department staff. The anticipated project savings will be between $85,000 and $100,000 if feasibility report preparation, design and construction observation are not outsourced. Project Area #1: Greenwood Shores Approximately 1.8 miles of streets are proposed to be milled and overlaid within the Greenwood Shores neighborhood located between Powers Boulevard and Lake Lucy. The streets in this area are 37 years old and 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. �o Kerber) 14 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. Staff had the sanitary sewer system televised 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. It is recommended to replace the bolts on the valves and some hydrants at this time.

The budgets will be reviewed and updated based upon current construction cost estimates. Project Area #2: Melody Hill Area This project area consists of 1.2 miles of streets southeast of the intersection of Trunk Highway 7 and Trunk Highway 41. This area is proposed to be added to the project given the additional street rehabilitation funding for 2013. j O 1 t� Y The table below summarizes the pavement condition indices (PCIs) and the construction year for each street section. A PCI of 100 represents a new street. For a local street, a PCI between 45 and 65 typically warrants a mill and overlay. The utilities in the project area are in fair condition therefore staff recommends that the streets with a PCI below 45 be milled and overlaid as well. Subgrade corrections would be done as needed.

The area is fully developed therefore there is no area to construct conventional storm water management facilities. Staff will gather information on the existing storm sewer pipes and draintile within the area and provide storm sewer improvement recommendations in the feasibility report. The sanitary sewer material within the Melody Hill neighborhood is PVC and vitrified clay pipe (VCP). There are no known issues with the sanitary sewer. The VCP sanitary sewer will be televised to determine the condition of the pipe and identify if inflow /infiltration exists since this particular material can be prone to these issues. Cast iron watermain pipe is within Murray Hill Road, Melody Hill Road (TH 41 to Murray Hill Road) and in West 65th Street. The remaining watermain in the project area is ductile iron pipe. The only documented watermain break in the area is on West 65th Street, which occurred in 2003. Staff recommends that the valves and some of the hydrants be replaced in conjunction with the project. 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.

The estimated PCIs are shown on the map. No major storm sewer improvements are proposed with this project area since the area is essentially fully developed. The watermain within this area is ductile iron pipe. There are no known watermain breaks within this area. It is recommended to replace the bolts on the valves and some hydrants at this time. The sanitary sewer is ABS pipe. It is recommended that the sanitary sewer be televised to determine if there are any structural deficiencies and/or inflow /infiltration issues with the pipe. r GAENG\PUBLIC\ 2013 PROJECTS \13 -01 Street Rehab \09 -24 -2012 order feasibility.docx Paul Oehme 2013 Street Rehabilitation Project September 24, 2012 Page 6 Project Area #4: Sandy Hook This area is proposed to be added to the project given the additional street rehabilitation funding for 2013. Most of the streets within this area were constructed in 1975; Sandy Hook Circle was constructed in 1981. Non- structural overlays were done in 2000 and 2011 and a slurry seal was done in 2001, however the estimated PCIs are low: between 13 and 34. Due to the fully- developed condition within this area, there is no opportunity to install stormwater management facilities within the area. The watermain within this area is ductile iron pipe; there are no documented watermain breaks. It is recommended to replace the bolts on the valves and some hydrants at this time. The sanitary sewer in this area is PVC pipe. There are no known issues with the sanitary sewer pipe. TRAILS 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. PROJECT FUNDING Funding for the project is anticipated to come from several sources. Forty percent (40 %) of the street improvement cost would be assessed back to the benefiting property owners, per the City's assessment practice. The remaining 60% of the street cost would be a City cost. Each project area would have its own proposed assessment. Funding for the Greenwood Shores neighborhood streets (Project Area #1) is proposed to be paid for through the revolving assessment fund. The other project area and the Rice Marsh Lake Trail are proposed to be paid for out of the cable TV fund. The storm sewer, sanitary sewer and watermain improvements replacement costs would be funded by the respective utility funds in the annual utility budgets. G:\ENG\PUBLIC\ 2013 PROJECTS \13 -01 Street Rehab \09 -24 -2012 order feasibility.docx Paul Oehme 2013 Street Rehabilitation Project September 24, 2012 Page 7 At the September 10 work session, staff had identified several other streets that are proposed to have improvements made in 2015 but are currently not funded. These additional street improvements are proposed to be funded using additional cable TV funds in the amount of $455,000 and $600,000 from the equipment replacement fund for a total of $1,055,000 in additional street improvements. The following is the anticipated recommended project budget and funding sources: Funding Source Amount Budgeted Assessments /Revolving Assessment Fund $950,000 (Greenwood Shores Neighborhood, Project Area # 1) Cable TV Fund $945,000 Additional Proposed Project Area (Areas 2 -4 + Rice Marsh Lake Trail Loop) Storm Water Management Fund $125,000 Water Utility Fund $175,000 Sanitary Sewer Utility Fund $150,000 $2,345,000 SCHEDULE The proposed project schedule is as follows: Neighborhood Meetings Accept Feasibility Report Public Hearing; Order Plans & Specifications Approve Plans & Specifications; Order Ad for Bid Assessment Hearing Project Begins Substantial Completion November, 2012 November, 2012 January 21, 2013 February 18, 2013 April 22, 2013 May, 2013 August 30, 2013 Attachments: Resolution Rice Marsh Lake Trail Exhibit G:\ENG\PUBLIC \_2013 PROJECTS \13 -01 Street Rehab \09 -24 -2012 order feasibility.doa CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA DATE: September 24, 2012 RESOLUTION NO: 2012- MOTION BY: SECONDED BY: A RESOLUTION AUTHORIZING PREPARATION OF FEASIBILITY STUDY FOR THE 2013 STREET IMPROVEMENT PROJECT NO. 13-01 WHEREAS, the areas for improvements in 2013 are as follows: Project Area #1: Melody Hill Area Mill and overlay of Chaska Road, Melody Hill Road, Murray Hill Road, West 65th Street, Crestview Drive (Galpin Boulevard to Chestnut Lane) and White Tail Ridge Court.
