Network Condition Assessment • Condition Assessment – Initially being completed 1/3rd of the City annually - 2016 • 2019 – entire network assessment survey being done in one year • Automated survey utilizes advanced technology to assess pavement surface and classify distresses per ASTM-D6433-11 • Data captured: Surface distresses - cracking, raveling, depressions • Data is managed in Cartegraph DTS Mobile Asset Collection Van 5
Street Maintenance Program Street Selection SMP Project Selection Cartegraph (Pavement Maintenance Management Software) is used to analyze budget scenarios, select projects and applications based on the Pavement Condition Index (PCI) Other components evaluated include: • Street classification (local, collector, arterial) • Multi-modal component (bus route) • Service requests (311 system) • Development density (urban, suburban, rural) • Coordination with utilities 6

Current Challenges • Refine SMP & Bond Programs to accelerate the reconstruction of “F” Streets • Work with local contractors to optimize program delivery recognizing material constraints and crew availability • Explore new technology & materials to enhance pavement performance • Refine and optimize project selection criteria and equity funding to be more impactful in areas with greatest needs 15
