2003 STREET MAINTENANCE PROGRAM By: Steve Jankowski, City Engineer PW CASE Background: Since 1981, the City of Ramsey has conducted an Annual Street Maintenance Program, whose purpose was to address the preventative maintenance of the City's asphalt pavements. The history of the City's paved streets and their maintenance ~s summarized on the attached table. From 1981 until 1990, the program consisted predominantly of sealcoating and the full cost of the program was special assessed. Beginning in 1991 until the present time, the City has financed 50% of the program cost. Because of the City Charter requirements, it is necessary to initiate the program in January in order to allow sufficient lead-time for construction to take place in early summer. The freqUency of preventative maintenance on the City's bituminous pavements has varied considerably, with some pavements receiving a sealcoating as little as two years and others as much as ten years after initial construction. In general, however, our current goal is to sealcoat a new bituminous pavement five years after construction and readdress maintenance at seven years thereafter. Currently, whenever possible projects are being aggregated in specific geographic areas of the City. The goal is to eventually concentrate the annual program in a specific geographic area of the City each year. A typical schedule for pavement maintenance would be as follows: Typical Bituminous Street Maintenance Cycle Year Action · 0 Construction 5 Sealcoat 1.2 Sealcoat 19 Overlay 24 Sealcoat It is anticipated that the 2003 street program will be comprised of four individual projects involving both bituminous overlays and sealcoating and includes three distinct funding sources. The tables below provide a summary of the mileage and these funding sources. 2003 Street Program Mileage Local Street MSA Streets Total Crackfill/Sealcoat 3.72 1.16 4.48 Bituminous Overlay 4.45 0 4.45 Total 12.50 6.94 9.33 53
