Road Management vs Pavin ing Management Road Management System 2 1 Comprehensive Pavement Management Trans. Plan Improve Repair Resurface Rehab Capacity June 7, 2019 Page 3
Pavement Management System The practice of planning for pavement maintenance and rehabilitation with the goal of maximizing the value and life of a pavement network. Also known as “Getting the Biggest Bang for our SPLOST Bucks”

Pavement Management System What is a PMS? • PMS is a process, not a piece of software Why PMS? • PMS does not make the decision for you, it is a tool that helps you make good, fact-based decisions • PMS can help manage our roads efficiently and cost-effectively • Save Stonecrest money in the long term • Generates results that are defensible, traceable, and repeatable What does it need? • Good data on road inventory, condition, and usage • PMS needs long term commitment from top to bottom
BASIC PAVEMENT MANAGEMENT QUESTIONS SYSTEM COMPONENTS Where is it? NETWORK INVENTORY How do we rate it? COLLECTION OF CONDITION DATA What condition is it in? PAVEMENT CONDITION INDEX When should we fix it? PREDICTION MODEL How do we fix it? TREATMENT SELECTION Which roads do we fix first? PRIORITIZATION

Pavement Condition In Index Revie iew Condition / Analysis Data Collection Philosophies/Strategies Define Inventory Rehabilitation Needs ($) and Timing
Condition Assessment Simplified Color Scale ASTM Rating Definition GOOD : Pavement has minor or no distresses and should require only 86-100 routine maintenance. SATISFACTORY : Pavement has scattered low-severity distresses that 71-85 should require only routine maintenance. FAIR : Pavement has a combination of generally low- and medium- 56-70 severity distresses. Near-term maintenance and repair needs may range from routine to major. POOR : Pavement has low-, medium-, and high-severity distresses that probably cause some operational problems. Near-term maintenance and 41-55 repair needs may range from routine up to a requirement for reconstruction. VERY POOR: Pavement has predominantly medium- and high-severity distresses that cause considerable maintenance and operational 26-40 problems. Near-term maintenance and repair needs will be intensive in nature. SERIOUS: Pavement has mainly high-severity distresses that cause 11-25 operational restrictions; immediate repairs are needed. FAILED: Pavement deterioration has progressed to the point that safe 0-10 operations are no longer possible; complete reconstruction is required.

NETWORK Prediction models help: INVENTORY ➢ Forecast PCI COLLECTION OF ➢ Optimal time of treatments CONDITION DATA PAVEMENT ➢ Remaining service life of CONDITION INDEX pavements PREDICTION ➢ Perform “what if” scenarios MODEL ➢ Enable long term planning TREATMENT SELECTION PRIORITIZATION

Factors to Consid ider When Sele lectin ing a Treatment • Pavement Condition • Structural Adequacy • Traffic Conditions • Urban or Rural • Climate Conditions • Availability of materials/contractors • Past performance June 7, 2019 Page 20
PMS COMPONENTS PAVEMENT MANAGEMENT SYSTEM COMPONENTS What roads do we fix first? NETWORK Ranking Approach: INVENTORY ➢ Use 1 or 2 criteria COLLECTION OF CONDITION DATA Example: Traffic Volume PAVEMENT (ADT) and PCI CONDITION INDEX ➢ Ratio of Benefit to Cost PREDICTION MODEL Goal: Obtain the most bang for each buck! TREATMENT SELECTION PRIORITIZATION
PMS Benefit its • Physical street characteristics database • Provide necessary data to legislators and managers for budget determination • Estimate repair costs based on key physical street factors and local unit costs • Road repair recommendations to get the most “Bang for the Buck” for efficient allocation of limited funds and improved network condition at the least cost June 7, 2019 Page 22
FULTON COUNTY’S PMS Experience
Pavement Management in in Fult lton County 2011 Pavement Condition Survey • First implemented Pavement Management System in 2002 using a windshield survey (COPACES) • County desired to revitalize its Pavement Management System using MicroPAVER • South Fulton County roads were evaluated in 2011 June 7, 2019 Page 24
Fult lton County Condition Map
Fult lton County Pavement Summary ry Good 23% Poor PCI = 71 - 100 48% PCI = 0 - 55 PCI = 56 - 70 Fair 29%
Fulton County 2011 Average Pavement Condition = 56 Critical PCI = 60 Do Nothing 100 Preventive 56 60 PCI Minor Rehabilitation 30 Major Rehabilitation & Reconstruction 0 Age $15-30 100 $5 - 10 Need $1 - 2 $/SF 0 Age
Fult lton County Decis isions • $2.2 million annual resurfacing budget • $170,000 annual maintenance budget • Resurfacing focus on PCI 45-55 with more detailed review to determine applicability of resurfacing treatment on these roads • Critical PCI of 60 in future and revisit • Develop deterioration models as data set increases • Update pavement management database regularly to maintain accuracy of system.

Pavement Management System Summary • PMS is a tool that helps you make good decisions • PMS can help manage Stonecrest’s roads efficiently and cost-effectively, and save money in the long term • PMS generates results that are defensible, traceable, and repeatable • PMS needs a detailed road condition analysis and a long- term commitment from top to bottom June 7, 2019 Page 29
Potential l Stonecrest Tim imelines and Recommendations Based on Tim imelines
SPLOST COA Committee Recommendation Recap (1 of 2) • Whereas the paving season starts in April 2019, and whereas there is not a requirement to have a SPLOST Program Manager under contract in order to begin work, the committee recommends City Council move forward with the most responsive and responsible qualified consultant selected by the city’s RFP process. June 7, 2019
SPLOST COA Committee Recommendation Recap (2 of 2) • The SPLOST COA Committee recommends the city not use a third-party program management company but instead use current City operations staff for Project Management so that the city can move forward with road pavement. If it is not possible to use current City operations staff, the committee recommends engaging a third-party engineering firm for project management. June 7, 2019 Page 32
