2.2 Pavement Condition The streets associated with this project have a combined length of approximately 2.2 miles. The Pavement Condition Index (PCI) method was used to determine the condition of the existing roads. The PCI rating is based on a visual survey of the pavement and is a number between 0 and 100 indicating the condition of a roadway, with 0 being the worst possible pavement condition and 100 being the best possible condition (i.e. a new road). The PCI method was developed by the United States Army Corps of Engineers and is widely used in transportation civil engineering. It is the City's general goal to have 75- percent of local streets at a rating of 70 or above. According to the pavement condition survey the streets have an average PCI rating of 35. A summary of the streets and their corresponding PCI ratings are shown in Table B.

A significant number of them have PCI ratings that have dropped into the 20's and 30's. The existing roads have failures including, but not limited to, transverse and edge cracking, medium to high severity patching, fatigue (alligator) and block cracking, and potholes. A number of the residential driveways in the area have street patching in front of them due to the settling of the street over time causing pooling of water in front of the driveways. A number of areas within the street section have water pooling in them as well. These puddles ice over in the wintertime and expand causing yearly deterioration of the street pavement. Figure 1, on the following page, displays pictures of the level of pavement deterioration in this neighborhood. Overall, the pictures provide a fair representation of the current state of street disrepair in this neighborhood. 5 15
