Street Program

During the summer of 2007, the city will be reviewing all streets in the city and will develop a new five-year plan.

Five-Year Program

In 2004, the city adopted its first five-year program, thanks to the new Pavement Condition Index. The list is being updated, and is expected to be posted after the summer of 2007.

To determine which streets are in need of repair, city staff uses GBAMaster Series, software that utilizes pavement condition index (PCI) to rate the condition of city roads on a scale of 0 (worst) to 100 (best).

A pavement with a PCI rating of 85 or more is considered to be very good and requires only minor annual maintenance, such as crack filling or minor patch work. A street is considered good if it has a PCI rating between 74 and 85, which generally indicates the need for some patching and surface treatment. A street is considered to be fair if it has a PCI between 50 and 74, which generally requires more extensive patching/overlay.

The aesthetics of the pavement's surface is not a consideration when determining the pavement condition index. The severity of the pavement distress and the density (extent of occurrence) are considered within each pavement segment. The distresses can consist of joint seal damage and scaling for concrete pavements or raveling and rutting for asphalt streets, to name a few.

All of the streets identified in this plan are subject to change, contingent upon yearly council approval and emergency repairs. Please note, streets identified in this plan are proposed for repair (i.e. slab replacement, asphalt overlay, aggregate seal coat, microsurfacing, curb replacement) not for total replacement. When replacing concrete slabs or repairing only a portion of a street, the new pavement will not match the existing pavement. The purpose of the program is to improve the structural integrity of the road, while making every effort to maintain the aesthetics of the street.

Funding for the street repair program comes from the city’s Capital Improvement Fund. In 1997, voters approved a half-cent sales tax dedicated to capital projects. Each year, the city budgets about $850,000 for street repairs. The city anticipates over $4.3 million in street improvements over the next five years.
