City Council approval requires a simple majority vote of the City Council present." At the August 11, 2014 work session, staff reviewed with Council the proposed 2015 Street Improvements to the Carver Beach area. Kerber Boulevard, a Municipal State Aid Route is also proposed to be resurfaced in 2015. Every year the City considers streets that are in poor condition to be rehabilitated or reconstructed. For the 2015 Street Improvement Projects, staff is proposing to rehabilitate approximately 4.3 miles of streets in the Carver Beach area and 1.4 miles of Kerber Boulevard. Website www.ci.chanhassen.mn.us The street segments within the proposed project were identified by the City's Pavement Management software in conjunction with site investigations and are shown on the map above.

Severe pavement distresses will be removed and replaced. Minor drainage improvements are also proposed to be addressed in the project areas. Miscellaneous water main and sanitary sewer manhole repairs are proposed for replacement in these areas. A feasibility report will be prepared by the Engineering Department staff. Design of the Carver Beach area improvements will be done in- house. Due to the large scope of the projects, plans for the Kerber Boulevard improvements will be completed by Kimley -Horn and Associates. Construction observation will be done by City staff. Project 15 -01: Carver Beach Area Approximately 4.3 miles of streets are proposed to be milled and overlaid within the Carver Beach Area. The streets in this area are 39 years old with the exception of Nez Perce Court, which was constructed in 1980. The streets were sealcoated in 1993 and 1998 and various areas were heavily patched in 2011. The northern portion of Lotus Trail was overlaid by City forces in 2006 and is therefore excluded from the proposed project. The street conditions in this area were last surveyed in 2013. The Pavement Condition Indices (PCIs) from the survey are shown on the map below.

Ringo Drive is currently gravel and is proposed to be paved. The profile of Woodhill Drive is proposed to be raised at the low point to alleviate some drainage concerns. Subgrade corrections would be done as needed. There is very little concrete curb and gutter within this project area. The area is fully developed therefore there is no area to construct conventional stormwater management facilities. Staff will examine the south end of Lotus Trail to identify potential stormwater improvements in the area. Staff will continue to 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 system will be televised to determine the scope of repair work. The Utility Department has performed a visual inspection of the sewer manholes and provided a list of work to be completed with this project. The water main in this area is ductile iron. City records do not show any water main breaks in this area. It is recommended to replace the bolts on the valves and some hydrants at this time. Most 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. Proiect 15 -02: Kerber Boulevard (north of West 78th Street Kerber Boulevard north of West 78th Street to Powers Boulevard is proposed to be resurfaced in 2015. This project area consists of 1.4 miles of improvement. The portion south of West 78th Street was resurfaced in 2011 with the West 78th Street improvements. Funding for this project is predicated on MnDOT advancing funds from the state aid account. Kerber Boulevard was constructed in 1980, with the exception of the southern leg between City Hall and West 78th Street, which was constructed in 1940. The street was overlaid in 1996 and last seal coated in in 2007. The PCI of the street segments are shown on the adjacent graphic. A PCI of 100 represents a new street. For a local street, a PCI between 45 and 65 typically warrants a mill and overlay. Subgrade corrections would be done as needed. The street is urbanized. Damaged curb and gutter will be replaced. Some storm sewer improvements are anticipated. G:.

Sanitary sewer crossings will be televised to determine the scope of repair work. Ductile iron water main is within the street. There is one documented water main break just north of West 78fl' Street. Staff recommends that the valves and some of the hydrants be replaced in conjunction with the project. 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. Curb ramps to the trail along Kerber Boulevard will be replaced in accordance with the Americans with Disabilities Act requirements. The trail along Kerber Boulevard has a low PCI rating as shown on the graphic to the right, and should be replaced at this time. No new trail segments are proposed to be added to Kerber Boulevard. The loop detectors to the signals at West 78a` Street will be evaluated to determine if they will be impacted by the proposed improvements. The City has received requests to install a pedestrian crossing from the Chanhassen Library to the strip retail center on the west side of Kerber Boulevard and where Redwing Lane intersects Kerber Boulevard. The City's consultant will analyze these areas and provide a recommendation. 44 42 KERBER BLVD nz LO yv Paw lg -0 o� N 0 L O n Cbanlussen V m Pond Pa h we• r z M m c-, M center ,L Part In r O G:E GWURLILI_2015 PROTECTS\15-012015 Street Improvements \10.2]- 2014orda Radbility.dou Paul Oehme 2015 Street Rehabilitation Projects October 27, 2014 Page 5 PROJECT FUNDING Funding for the project is anticipated to come from several sources. Forty percent (40 %) of the street improvement costs in the Carver Beach area would be assessed back to the benefiting property owners, per the City's assessment practice. The remaining 60% of the street costs would be a City cost. The majority of the Kerber Boulevard road and trail improvements will be paid using Municipal State Aid (MSA) funds from the State. A portion of the street improvement costs are proposed to be assessed to the Carver County CDA and the townhome development on the southwest corner of Kerber Blvd and Santa Vera Drive. The proposed assessment methodology and estimated assessment will be included in the feasibility report. The storm sewer, sanitary sewer and water main improvements replacement costs would be funded by the respective utility funds in the annual utility budgets. The following is the anticipated recommended project budget and funding sources: Funding Source Amount Budgeted Assessments/Revolving Assessment Fund $1,850,000 Municipal State Aid Fund (MSA) $1,400,000 Stormwater Management Fund $125,000 Water Utility Fund $125,000 Sanitary Sewer Utility Fund $75,000 $3,575,000 Budgets for the proposed work were included in the proposed 2015 CIP. The budgets will be reviewed and updated based upon current construction cost estimates.

While proper preventative maintenance extends the e street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. anon projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have ted to a point where rehabilitation will no longer be practical, reconstruction of the skeet is necessary. A feasibility study is written to the merits of the project and scope of work '.12 improvement project included a pedestrian trail along the fast 2,500 feet of Bluff Creek Drive. The resulting "gap" represents a the City's trail system south to Flying Cloud Drive. Bluff Creek Drive is a difficult stretch of road to negotiate as a pedestrian in a trail. This trait semrent is planned to be constructed along with the 2017 MSA street reconstruction.
