Sealcoats were performed in 1993, 1997 and 2005. A non-structural overlay was done on the northern leg of Lake Susan Hills Drive, Egret Court, Heron Drive and Ibis Court in 2002. Due to drainage issues in the area, approximately 1,050 feet of drain tile was installed on the east side of Flamingo Drive in 2011. The proposed improvements consist of reclaiming the pavement surface; severe pavement distresses will be removed and replaced. Some drain tile may be installed with the project. Water main gate valve and hydrant bolt replacements are anticipated for replacement in these areas. Minor sanitary sewer repairs are also expected. 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 FUNDING 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 costs would be a City cost. Each project area would have its own proposed assessment. Any 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 $922,400 Storm Water Management Fund $75,000 Water Utility Fund $75,000 Sanitary Sewer Utility Fund $40,000 $1,112,400 SCHEDULE The proposed project schedule is as follows: Neighborhood Meeting October, 2016 Accept Feasibility Report October 24, 2016 Public Hearing; Order Plans & Specifications November 28, 2016 Approve Plans & Specifications; Order Ad for Bid January 23, 2017 Assessment Hearing March 27, 2017 Project Begins June, 2017 Substantial Completion September 1, 2017 Attachments: Resolution CIP Sheets G:\ENG\PUBLIC\ 2017 PROJECTS\17-01 Street Rehab\20160912 order feasibility.docx CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES,MINNESOTA DATE: September 12,2016 RESOLUTION NO: 2016-XX MOTION BY: SECONDED BY: AUTHORIZE PREPARATION OF FEASIBILITY STUDY FOR THE 2017 STREET REHABILITATION PROJECT NO. 17-01 WHEREAS,the areas for improvements in 2017 are as follows: Egret Court Mallard Court Flamingo Drive Merganser Court Heron Drive Pelican Court Ibis Court Tern Court Kingfisher Court Thrush Court Lake Susan Hills Drive NOW,THEREFORE,BE IT RESOLVED that the Chanhassen City Council hereby authorizes preparation of a feasibility study for the 2017 Street Rehabilitation Project No. 17-01.

Current 5-year plan shows the following neighborhood areas: 2016-North Manor Road,Washta Bay Road,Tanagers Lane,Sandpiper Trail,Piper Ridge Lane,Minnewashta Woods Drive,Fox Path area, Lone Cedar area,Ches Mar Drive and Stoughton Ave MSA-Park Road overlay and Park Place i 2017-Flamingo Drive area ' MSA-Bluff Creek Drive overlay and Bluff Creek Drive Trail extension. 2018-Orchard Lane,Forest Avenue,Forest Circle,Oriole Avenue,64th Street and 96th Street 2019-Fox Path area,Frontier Trail(north of 77th Street),Choctaw and Kurvers Point MSA-Minnewashta Parkway overlay 2020-Chan View area I 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. The Highway 212 improvement project included a pedestrian trail along the first 2,500 feet of Bluff Creek Drive. The resulting"gap"represents a missing link in 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 the absence of a trail. This trail segment is planned to be constructed along with the 2017 MSA street reconstruction.
