CC Regular Session Date: 04/12/2011 By: Tim Himmer Engineering/Public Works Item #: 6. 1. Information Title: Public Hearing for City Improvement projects #11-01 through 11-06; 2011 Street Maintenance Program Background: Routine maintenance is the most economical method for safeguarding the public investment in bituminous paved streets. The bituminous street surface weakens as a result of sunlight exposure, precipitation, freeze/thaw cycles and traffic loading. As a result, the asphalt components of the bituminous become brittle and susceptible to cracking. Once water is able to penetrate surface cracks into the road base, pavement deteriorates at an accelerating pace. To avoid this rapid deterioration, it is the goal of the City to address the preventative maintenance needs of its street system on a periodic basis. The goal of seal coating is to restore the imperviousness of the pavement. Eliminating water penetration and pavement oxidation retains the flexibility of bituminous pavement. Unlike seal coats, which only preserve the flexibility of the bituminous, an overlay provides additional strength to the pavement structure. Streets receive a bituminous overlay when they are no longer able to benefit from a seal coating operation. The 2011 Street Maintenance Program (SMP) consists of six individual projects addressing the maintenance needs on 13.47 miles of City streets. Projects 11-01 through 11-04 will cover 11.93 miles of City streets, and receive a seal coat preceded by sealing of cracks having widths that exceed one -quarter inch (1/4"). Projects 11-05 and 11-06 will address 1.54 miles of City streets, and receive a one and one-half inch (1 ''/2") bituminous overlay on top of the existing bituminous pavement. The proposed seal coating projects consist primarily of streets that were recently overlaid, a majority of which were done in 2006, and they will be assessed according to the City's revised policy on seal coat assessments (22% of actual total project costs). The proposed overlay projects consist of streets that have been combined by subdivision or similar lot sizes, and will be assessed per unit. The attached feasibility study outlines all the streets proposed for maintenance activities, estimated costs, and the preliminary assessment role. It also contains a general mapping of each project and lists all the parcels receiving benefit; noting the number of shares being assessed. Notification: Per the requirements of State Statute, benefiting property owners were notified of the public hearing via direct mailings, and the corresponding notices were published in the Anoka County Union. Approximately 485 properties are proposed to be assessed for the 2011 SMP. Observations: The 2011 SMP was reviewed by the Public Works Committee on February 15, 2011, and they recommended advancing it to the City Council. On March 8, 2011 the City Council received the feasibility study and ordered the public hearing, which was set for April 12, 2011. The attached feasibility study will be the basis of the public hearing and 2011 SMP. Council is asked to hear from the property owners that will be affected by this project and provide any required revisions to the report, scope of the project, and/or proposed assessments. A public open house was held on March 30, 2011, and 10 property owners attended the meeting to ask questions and provide input on making the project more successful. Each concern identified will be investigated and attempts
