CASE # ` • 2007 ANNUAL STREET MAINTENANCE PROGRAM By: Steven J. Jankowski, City Engineer Background: At tonight's meeting, public hearings will be held on Improvement = Projects #07 -02 through #07 -11, which comprise the 2007 Annual Street Maintenance Program. The City has a considerable investment in the 161 miles of bituminous street for which it is responsible. The City has established the practice of applying timely preventative maintenance to the pavements to preserve this investment. Although budget constraints and pavement conditions may alter the actual schedule, the table below presents an idealized timetable for pavement maintenance. Typical Bituminous Street Maintenance Cycle Year Action 0 'Construction 5 Sealcoat 12 Sealcoat 19 Overlay 24 Sealcoat • The Ci ty program has had an annual maintenance ro am since 1981. Through the 1990 program it was the City's policy to assess the total cost of the maintenance programs. Beginning in 1991, the City changed the policy and currently assesses 50 percent of the total project cost, with the City general fund financing the remaining half. A copy of the current assessment policies is included as Appendix B of the attached feasibility study. The 2006 program consists of eleven individual projects addressing the maintenance needs on 20.73 miles of City streets. Projects 07 -01 through 07 -07 which covers 15.27 miles of City streets, will receive a sealcoating preceded by sealing of cracks having widths which exceed one - quarter inch. The 2007 program includes sealcoating of 3.53 miles of MSA streets and is included in project 07 -07. Projects 07 -08 through 07 -11 which involve 5.46 miles of street, will receive a one and one -half inch bituminous overlay of the existing bituminous pavement following the repair of failed areas by the Public Works Department. The 2006 program is proposed to be financed through a number of funding sources including MSA funds, developer escrows, special assessments, and City general funds. A summary of the anticipated funding is presented below. Project 06 -01 will not be an assessment project since funds for the first sealcoating of newly constructed streets have been escrowed by the project developer for this purpose. • Project 07 -07 is comprised of collector MSA streets which experience higher project costs because of their wider pavement and need for stripping and pavement markings. In addition, these streets have lower unit densities as a result of the effort made to minimize —91—
