The City of Oak Harbor contracted with Pavement Services, Inc. (PSI) to implement a StreetSaver pavement management system (PMS) to manage the Oak Harbor street system. The City manages approximately 71 centerline miles of local, collector, minor arterial and principal arterial streets.

The objective of this project was to perform a visual survey to rate the pavement condition of the City street system and implement a StreetSaver PMS to develop maintenance and repair recommendations over a five-year period.

The City of Oak Harbor chose StreetSaver as its PMS. StreetSaver was developed in 1987 by the Metropolitan Transportation Commission (MTC) in the San Francisco Bay Area.1 The purpose of StreetSaver is to provide cities and counties with a simplistic PMS in order to better maintain their local streets and roads. By using a PMS like StreetSaver, agencies have the ability to improve pavement maintenance and rehabilitation (M&R) techniques and practices.

PAVEMENT MANAGEMENT METHODOLOGY

Depending on design life and the timing of preventive maintenance, the typical pavement condition trend begins with a slight deterioration immediately after construction followed by a long period where the deterioration levels off. During the leveling off period, the deterioration of the pavement slows relative to time. This long period of slower deterioration is when the majority of the desired condition, use, and life of the pavement occurs. At the end of the “leveling off” period, there is a transition point referred to as the critical PCI. After the critical PCI is reached, the pavement condition typically deteriorates more quickly into a state of poor condition. An example of typical pavement deterioration is presented in the figure below.
