City Council approval requires a simple majority vote of the City Council present." DISCUSSION The Capital Improvement Program has planned for the rehabilitation of Lake Drive East in the summer of 2018. Staff used the City's Pavement Management Program and site investigations to determine the project extents, as illustrated in Figure 1. The project includes approximately 0.7 miles of urbanized streets. S ,, ... _ 1 -.r fes..." ' '- Nr.Ai ,�� W761h3 Fvd .

The 2015 surveyed pavement conditions were 66.8 and 67.3 on the west and east sides of Dakota Avenue, respectively as shown in Figure 1. A PCI of 100 represents a new street. According to 2015 traffic counts Lake Drive East carries approximately 3,600 vehicles per day. The proposed project includes intersection improvements at the Dakota Avenue/Lake Drive East intersection. The intersection has a stop condition for both directions of the Lake Drive East traffic. Residents in the neighborhood to the south are concerned with eastbound Lake Drive East traffic failing to yield to northbound Dakota Avenue traffic. There is also concern for pedestrian and bicyclist safety at this intersection. The engineering consultant will collect and analyze traffic volume, turning movement and accident data to provide recommended intersection improvement alternatives. Dakota Avenue is also a Municipal State Aid Route constructed in 1986 and sealcoated in 2005. As shown in Figure 1, the 2015 surveyed pavement condition was 74.4, which is higher than expected due to the extensive patching along the street corridor. A 190-foot long, raised concrete median separates north- and southbound Dakota Avenue. The northbound portion consists of two through lanes, one left turn lane, and one right turn lane. The southbound portion consists of two lanes that transition to a right turn and a through/left turn lane at the Lake Drive East intersection. According to 2015 traffic counts, Dakota Avenue carries approximately 4,500 vehicles per day. Staff recommends including Dakota Avenue in the project due to the underlying pavement condition, the traffic volume, and the anticipated intersection improvements at Lake Drive East. Twelve-inch ductile iron water main is within Lake Drive East and 8" cast iron water main is within Dakota Avenue. There are no documented water main breaks within the project area. Some valves and hydrants are anticipated to be repaired/replaced with this project.

Staff sent a request for proposals to three engineering companies: HTPO, Kimley-Horn &Associates and WSB &Associates. All consultants submitted proposals, as summarized below: HTPO Kimley-Horn WSB & & Associates Associates Submitted prior to the deadline ✓ ✓ ✓ Proposal format ✓ ✓ ✓ Transmittal letter submitted ✓ ✓ ✓ Members of the consultant team identified ✓ ✓ ✓ Understanding of the project ✓ ✓ ✓ Total Hours 863 810 745 Total Cost $104,844 $98,795 $87,396 The proposed WSB team worked on the Park Road/Park Place (2017) rehabilitation project and has extensive street and utility reconstruction project experience including the following projects in Chanhassen: Orchard Lane(2018), Minnewashta Manor(2017), Minnewashta Heights (2012), Red Cedar Point (2011), and the Erie Avenue Area (2010). Their work in Chanhassen and other communities has been satisfactory. The consultant contract will be a time and materials based work not-to-exceed amount. Depending on the outcome of the Dakota-Lake Drive intersection analysis additional design services may be required. As with all engineering contracts, the consultant must submit periodic invoices that staff will review before processing. The consultant will be required to submit timesheets verifying the hours worked on the project and expense sheets. Staff will review the invoices and expense sheets for accuracy and conformance to the contract. FUNDING Budgets for the proposed work have been included in the 2017 CIP. The budgets will need to be reviewed and updated based upon current construction cost estimates and after the feasibility report is drafted. Funding for the project is proposed to come from mainly Municipal State Aid and has been budgeted for in the 2017 Capital Improvement Plan as follows: Paul Oehme Lake Drive East Rehabilitation Project No. 18-02 May 8,2017 Page 5 Funding Source Budget Municipal State Aid Funds $1,100,000 Sanitary Sewer Replacement Fund $30,000 Water Main Replacement Fund $30,000 Total $1,160,000 Assessments are recommended consistent with the City's policy of assessing 40% of the street improvements to the benefiting properties at an interest rate of prime plus 2% over 8 years.

Current 5-year plan shows the following neighborhood areas: PI 2017-Minnewashta Manor area and Lake Susan Hills Drive area MSA-Park Road and Park Place 2018-Orchard Lane arca MSA-Lake Drive East and Dakota Ave(Highway 5 to Lake Drive East) IP 2019-Choctaw area,Kurvers Point area and 96th Street MSA-Minnewashta Parkway overlay and trail 2020-Chan View area MSA-Lake Lucy Road(Highway 41 to Galpin Blvd)and trail 2021 -Stone Creek area and Ches Mar Drive 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 when utilities 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.
