• 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

Street Maintenance Program Street 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

Picture [District 10 – Rowe Drive (Thousand Oaks to Cul-de-Sac), Mill & Overlay] City’s Street Maintenance Program has goal of maintaining the roadway network at an overall “Good” rating i.e. Pavement Condition Index of 70 or above. Pavement Preservation: PCI > 70 rehabilitation: PCI < 70 Average $ to keep average PCI @ 70 - $75M Street Maintenance Program (SMP)— as of May 31st FY 2016 $64.0 million = 833 of projects, 832 completed projects (99.9%), 1 pending (D2 - Lamar from Austin St to N New Braunfels), project is being delivered as part of FY 2017 Bond Project – anticipate completion July 2019 FY2017 $64.0 million = 888 of projects, 880 completed projects (99.1%), 8 pending projects are utilizing CDBG funds, estimated completion of program by January 2020 FY 2018 $99.0 million (includes $10.0 million in savings)= 1,260 projects (includes 57 projects from savings) 1,131 completed (90%), 129 pending projects, all FY 18 projects will be completed by March 2020 FY 2019 $110.0 million = 1,214 projects, 493 completed (41%), 721 pending projects, 1,076 projects completed by September 2019. 138 projects to be completed by March 2020 FY 2020-2024 SMP under development 10 Year History of SMP Recession years of 2009-2014, less money was allocated A bump in 2013 was due to $4.5M funds from ATD Starting in FY 2015, we begin to invest more

2018-2019 Street Improvement Strategy
By completion of FY 2019 SMP in March 2020, all districts projected to have average PCI score above or at 70
More than 760 miles of roadways maintained (475 miles in Council Districts with low PCI)
Presenter
Presentation Notes
As mentioned on the previous slide, City’s SMP has goal of maintaining the roadway network at an overall “Good” rating i.e. Pavement Condition Index of 70 or above. Analysis of the street condition network in FY2017 showed that while the average Pavement Condition Index (PCI) of the City’s network was above 70, there were five council districts (D1, D2, D3, D5 & D10) with an average PCI score below 70. In FY 2018, Council set a goal to bring all districts above the 70 point average within two years by increasing the SMP budget of $64M by an additional $35million specifically targeting the low PCI districts. In FY 2019 the budget was further increased by an additional $11M to $110 to enhance the citywide network. Below are the F Streets improved within the 2018 & 2019 two-year strategy
Equity-Based Street Maintenance Funding
11
Presenter
Presentation Notes
Prior to FY2018, distribution of SMP dollars was roughly proportionate across the districts considering the SMP, 2017 Bond and Linear Parks Program. Starting in FY 2018, distribution of funds included an equity-based approach (allocations based on street needs). In FY2018, $64 million base was distributed roughly proportionate across the districts with the additional $35.0 million specifically targeting five districts with the lowest PCI scores. (Districts 1, 2, 3, 5 & 10) In FY 2019, $64 million base was distributed roughly proportionate across the districts with the additional $35.0 million specifically targeting five districts with the lowest PCI scores. (Districts 1, 2, 3, 5 & 10), and the additional $11.0 million was distributed based on percent of C& D streets inside loop 410 and older areas in D8 & D9. FY 2019 Status: $110.0 million = 1,214 projects, 702 completed (58%), 512 pending projects, 1,076 projects completed by September 2019. 138 projects to be completed by March 2020 Continuing the equity-based funding strategy that began in San Antonio in FY 2018, the FY 2020 Proposed Budget maintains the Street Maintenance Program at $110 million and continues to allocate funding based on the equity approach. Proposed distribution for FY 2020 is a 50/50 split. First 50 is to be based on the size of the districts network and the other 50 % is to be based on the condition of the districts network Size of District’s Network Budget Distribution – Percentage calculated as number of square yards per districted divided by total number of square yards city-wide (74.4M sq. yds.) Condition of District’s Network Budget Distribution – Percentage calculated as estimated amount to repair streets within each district divided by estimated amount to repair streets city-wide ($1.5B) FY 2020-2024 SMP under development - emailed to Councilmembers. FY20 – 1377 projects, 395 Miles, 5-Year FY2020-2024 – 6,202 of projects 1,880 of miles

Presentation Notes
Background (Introductory Remarks) San Antonio has over 4,100 (4,155) Miles of Streets in the Network, that are maintained by the TCI 70% of the network is in Fair to Excellent Condition, while 30% is in Poor to Failed Consistently residents have indicated Street Maintenance is a high priority. Consequently, Mayor, Council & City Management have continued to invest in maintaining the network. Street maintenance budget was initially at a $35M level, as the economy has improved, the City has incrementally increased the funding to its current level of $110M (Funding has tripled) Circumstances that impact delivery of SMP include project complexity, weather, utility coordination, and contractor availability. Since Council has indicated a willingness to maintain this funding level for the foreseeable future, TCI is revamping its SMP delivery plan to ensure that allocated funds are invested in a timely manner. Moving forward, TCI will ensure the following to successfully deliver the SMP: Two-Year program delivery & Continue to leverage City in-house and Contract forces Pavement Preservation (12 months) City in-house and Contract forces Mill & Overlay (12 months) Contract forces Reclamation/Reconstruction (24 months/2 yrs Design, Utility Coordination & Construction) Contract forces Aggressively Secure Contractor Capacity - Three tiers of packages (Small (<$2.5M), Medium (2.5>$10M) & Large ($10M>$20M) - varying size of packages will lend both large and smaller businesses to all participate while securing contract capacity. Engage with contracting community and communicate schedule. Utility Coordination – Brief partner agencies (SAWS & CPS) on two year plan Industry Outreach – Staff working with industry consultants to ensure project teams are adequately staffed to manage the development and execution of projects. Using consultants SMP Contract Delivery Staffing Fully staffed SMP team results in higher level of accuracy and effectiveness in project evaluation, application selection, utility coordination, adequate site management, & enhanced community outreach. TCI has sufficient staffing for delivery of program – 21 total TCI positions & 13 consultants for a total of 34 staffing towards delivery of SMP

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
