<br />Consulting Services Agreement between City of San Leandro and Last revised 04/16/2026 <br />NCE for Pavement Cut Impact Fee Study Exhibit A – Page 2 of 5 <br />o Typical asphalt thickness, aggregate base thickness, and R-values <br />o Design Traffic Index (TI) <br /> <br />Task IB.2 Historical Evaluation <br />Under this task, NCE will analyze the City’s historical pavement inspection data in the StreetSaver® <br />database and compare characteristics of street sections with and without cuts to evaluate impacts on <br />pavement service life due to cuts. <br /> <br />The City’s StreetSaver® database contains inspection data since 2007. This robust database is <br />expected to provide over 500 sample units with or without cuts that can be used for the analysis. The <br />rehabilitation date will be used to determine the pavement age at the time of the cut. <br /> <br />Subsequently, NCE will review the City’s StreetSaver® database to extract sections with cuts and <br />compare their PCIs before and after the cuts for different functional classifications and condition <br />categories. Pavement deterioration curves of cut and no-cut sections will be developed using the <br />historical data from the City’s database similar to Figure 4. The pavements with cuts are expected to <br />deteriorate faster compared to the pavements without cuts. The results will be summarized for and used <br />to develop a fee schedule in Task IC. This task assumes labor related to big-data processing and <br />analysis. <br /> <br />Task IB.3 Field Evaluation <br />A field evaluation of a minimum of 24 sites containing cuts on streets of different functional <br />classifications and condition categories will be conducted. For each site, a pair of 100-ft sections (one <br />with cut and one without cut) will be evaluated using field testing and PCI survey to assess the impact of <br />cuts on the pavement. <br /> <br />Deflection testing will be conducted at the sites on both sections using a falling weight deflectometer to <br />assess the loss of structural capacity due to the presence of cuts. A PCI survey will be conducted on the <br />pair of sections within the selected sites to assess the functional damage. <br /> <br />Task IB.3.1 Site Selection <br />This task will require interaction with City staff, as NCE will have to review the sites provided and select <br />appropriate sites for testing. Our cost estimate assumes a total of 24 test sites; each site will have a <br />section with a cut and one without a cut (Figure 5) for comparison. <br /> <br />NCE will mark a total of 54 sections with and without cuts (27 test sites) with white paint in the field. An <br />additional 3 sites will be marked as optional if field testing cannot be performed on any of the first 24 <br />sites. <br /> <br />This task includes labor related to field visit, site inspection, site marking for field testing (coring and <br />deflection testing), travel time, reimbursable costs of meal and transportation. <br /> <br />Task IB.3.2 Structural Analysis <br />Deflection testing will be conducted along the cut, 2 feet away from the cut (known as the zone of <br />influence) as well as on the section with no cuts (see Figure 6). The premise is that cutting into a <br />pavement will structurally weaken the surrounding areas due to the “slumping” effect. <br />Docusign Envelope ID: F4FCBFC6-F136-48C5-BF44-69A3B4443EB2
