The City was selected for a grant for Round 24 of the Pavement Management <br />Technical Assistance Program (P-TAP), and MTC selected AMS Consulting to perform the <br />City’s 2023 PMP update. <br /> <br />The PMP program divides the City’s paved portion of the street network into 1,341 segments <br />based on the construction of the roadway. Each segment is inspected in the field every two <br />years and given a PCI rating that ranges from 0 (failed) to 100 (new), which are allocated into <br />one of five condition categories as shown in Table 1 below. In addition to the PCI rating, the <br />cost of the backlog of work is determined, with backlog defined as the cost of a project <br />recommended for treatment in the first year but deferred to the following year(s) due to <br />funding constraints. <br /> <br />Table 1: Overview of City’s Current Pavement Condition <br />(Table ES-1 in Attachment 1, page 4) <br /> <br /> <br /> <br /> <br />The pavement condition degrades on a reverse exponential curve as shown in Figure 1 below. <br />It is most cost-effective to maintain the streets in “good to excellent” condition. As the PCI <br />decreases, the cost to maintain the system increases exponentially. The theoretical ideal PCI <br />is 87, which is the point at which the network is most cost-effectively maintained. <br /> <br />Figure 1: Pavement Life Expectancy <br />(Figure 1 in Attachment 1, page 11) <br /> <br />Page 161 of 228
