City Council approval requires a super majority vote of the City Council present." BACKGROUND At the June 22, 2015 work session, staff reviewed with Council the proposed 2016 Street Improvement areas. Staff also discussed with the Council the need to make improvements to more local streets than what is currently budgeted in the Capital Improvement Plan. On October 26, 2015, the City Council authorized preparation of the feasibility study. On November 18, 2015, staff held an Open House for the proposed project. On December 14, 2015, the City Council accepted the feasibility study and ordered the public hearing. D3ISCUSSION UVF ? t r � ` ;; t 1 Every year the City considers . , streets that are in poor ��• A r condition to be rehabilitated or reconstructed.o For the 2016 Street Rehabilitation Project, staff is proposing to rehabilitate approximately one mile of streets in the Trolls -Glen �4 Ione Cedar area and Fox .; 01110 OWN, Chase neighborhoods. The f i h street segments within the F: proposed project were�' l identified by the City's Pavement Management Software in conjunction with site investigations. Chanhassen is a Community for Life ® Providing for Today and Planning for Tomorrow Paul Oehme 2016 Street Rehabilitation Project: Public Hearing; Order Plans & Specifications February 8, 2016 Page 2 The proposed improvements are similar to what was done in the Carver Beach area during the summer of 2015: reclaiming the pavement surface and the Class 5 underneath the pavement, removing the top four inches of reclaimed material, and paving two, two-inch lifts of asphalt. Severe pavement and subgrade distresses will be removed and replaced. Minor drainage improvements are also proposed to be addressed. The water main in each project area is thought to be in relatively good condition. Trolls -Glen Area (0.4 miles) The streets in this area are between 40 and 44 years old and were sealcoated in 1994, 1999 and 2008. The street conditions in this area were last surveyed in 2014. The Pavement Condition Indices (PCTs) from the survey are shown on the adjacent map. A PCI below 45 typically warrants reconstruction however the utilities in the area are in fair condition, therefore staff recommends reclaiming the streets at this time. Subgrade corrections will be done as needed. Lone Cedar Lane was originally constructed as a rural residential street in 1971 when the sanitary sewer and water main were installed in the area. At that time, there were only lots along the southern portion of what is now known as Lone Cedar Lane. In 1975, the Trolis-Glen development was approved and the remainder of Lone Cedar Lane, W. 77th Street and Forest Ridge Circle were constructed. The streets in the Trolls -Glen development were urbanized, leaving the southern 500 feet of Lone Cedar Lane as the only rural section within the Street Project leo. 16-05 project area. The proposed improvements include urbanizing this 500 foot section. Lone Cedar Circle is not included in the project as it was improved by MnDOT in 2012 when the Lone Cedar Lane access to State Highway 5 was removed. The water main in this area is ductile iron. City records do not show any water main breaks in this area. The valves and hydrants in the project area are in good condition. The sanitary sewer system in this area will be televised to determine the scope of sanitary sewer repairs. The feasibility study includes costs to replace the sanitary sewer lids and install I&I barriers in each manhole. The feasibility estimate includes 400 feet of drain tile based on field observations. Based on the Streets department inspection, minor replacement and repairs of the existing storm sewer will be completed with this project and are included in the estimated storm sewer costs. The Trolls -Glen neighborhood includes 460 feet of W. 77th Street that is within the City of Victoria. Staff from Victoria was notified of Chanhassen's proposed project and has budgeted for their portion of W. 77th Street. 'The majority of street work in the Trolls -Glen area is in Chanhassen.

The City of Victoria would reimburse the City of Chanhassen for these services. The feasibility study, cost estimates and budgets presented in this report do not include the work to be performed in Victoria. Fox Chase Area (0.6 miles) The streets in this area are 30 years old and were sealcoated in 1993, 1998 and 2007. The street conditions in this area were last surveyed in 2013. The Pavement Condition Indices (PCIs) from the survey are shown on the adjacent map. A PCI below 45 typically warrants reconstruction however the utilities in the area are in fair condition, therefore staff recommends reclaiming the streets at this time. Subgrade corrections will be done as needed. The Fox Chase area includes a large paved arca commonly referred to as an "eyebrow". This area is approximately 90 feet wide and 100 feet long. Staff has drafted an alternative to the "eyebrow" in order to minimize the mass of pavement surface in this area. Staff will meet with the residents that would be affected by this reconfiguration to discuss the alternatives. The streets within the project area are residential streets with concrete curb and gutter and storm sewer to facilitate runoff. The feasibility estimate includes 750 feet of drain the based on field observations. Minor replacement and repairs of the existing storm sewer is expected with this project and are included in the estimated storm sewer costs. The water main in this area is ductile iron. There is one documented water main break in this area. The valves and hydrants in the project area are in good condition. The sanitary sewer system in this area will be televised to determine the scope of sanitary sewer repairs. The feasibility study includes costs to replace the sanitary sewer lids and install I&I barriers in each manhole. g:\eng\public\_2016 projects\16-05 2016 street resurfacing project\communication\20160208 ph order plans & specs.docx Paul Oehme 2016 Street Rehabilitation Project: Public Hearing; Order Plans & Specifications February 8, 2016 Page 4 PROJECT U N Forty percent (40%) of the street improvement cost is proposed to be assessed to the benefitting property owners, per the City's assessment practice. The remaining 60% of the street costs and all of the utility costs would be paid by the City.

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 or a trail. This trail segment is planned to be constructed along with the 2017 MSA street reconstruction.
