• 22 Fortune 500 firms (4th highest) • Represents 1/3rd of Texas GDP
Economy • 12 Counties (3nd largest MPA) • 160 Municipalities • Multiple transportation providers
(TxDOT, NTTA, CDA, Public, etc.)
Area
• 2017: 7.2 million people • 2045: 11.2 million people • 6th largest MPA nationwide
Population
Regional Context for Asset Optimization Dallas-Fort Worth Metroplex – “The Big Picture”
3
Population/employment growth nearly 50% through 2045 Increased vehicle-miles of travel, delay, and congestion costs,
while numerous existing infrastructure/system burdens remain Mobility 2045 Plan identifies less than 1/3rd funding necessary to
eliminate the worst congestion and maintain state of good repair

Transportation Challenges for a Dynamic Region
Mobility 2045 Plan – https://www.nctcog.org/trans/mtp/2045/index.asp
4
Improvement options becoming increasingly limited: Flat/declining revenues and purchasing power from gas/sales taxes Reduced use of and desire for innovative financing/tolls Growing maintenance needs (exacerbated by extreme weather events)
New Federal/State funding recently approved: Fixing America’s Surface Transportation (FAST) Act Proposition One/Seven – Voter approval > 80% Ending DPS/DMV gas-tax diversions
Mobility 2045 Plan identifies $135.4 billion for improvements: Existing system maximization strategies > 4% compared to previous MTP Applies holistic project selection/prioritization process (House Bill 20) Initial inclusion of FAST Act performance measurement rules/targets

Regional Context for Asset Optimization (cont.)
Monitoring of Local CIP/Bond Program Implementation
NCTCOG conducts routine local government communication regarding capacity, maintenance, and enhancement projects for roadways within the regional travel demand model network:
Current street improvement spending for largest DFW cities: Dallas – $534 Million (2017) Fort Worth – $262 Million (2018) Arlington – $160 Million (2014) Plano – $90 Million (2017) Garland – $65 Million (2017)
Though significant expenditures are allocated to lane-mile expansion to accommodate growth, increasing fund shares over time are being directed toward preservation and rehabilitation
Irving – $100 Million (2017) Grand Prairie – $56 Million (2017) McKinney – $64 Million (2015) Frisco – $125 Million (2015) Mesquite – $125 Million (2015)

Analyzing Local Asset Management Needs/Performance
Some local governments are reporting asset management status, needs, and goals
Needs vastly outweigh resources and goal attainability is difficult
Notable examples: City of Dallas (2017)
Total funding needs = $5.3 Billion 2006 City Council goal – 87% overall
satisfaction rate; > 80% in all districts August 2016 – 73% (11,775 lane-miles)
City of Irving (2017) Average PCI score – 72 (1,440 lane-miles) > $800 Million per year to maintain PCI

Climate/Weather Challenges to Mobility & Functionality

2015 NCTCOG Vulnerability Assessment Study Climate Change/Extreme Weather is a Current Problem
Eight of the top-10 warmest years in DFW have occurred after 1998: #1 – 2017; #2 – 2012; #3 – 2006; #4 – 2016 Heat concerns at all hours of the day (high
minimum temperatures also critical)
Large DFW weather variations: 2011 Summer Heat = 72 days > 100o
(average – 18 days)
2014 Precipitation Total = 21.32 inches (fifth year of worst drought since the 1950’s)
2015 Precipitation Total = 62.61 inches (wettest year on record)
2017 Last Freeze – January 8th (average – March 12th)
9
“Business-as-Usual” emissions scenario translates to substantial temperature rises and soil moisture reduction by year 2100:
Mean temperature > 8o F compared to current average (extreme > 13o F)
Lower annual rainfall, but punctuated by storms of greater intensity
Infrastructure effects magnified due to large regional distribution of high-plasticity soils

Notable Findings – Significant Future Climate Change
2015 NCTCOG Vulnerability Assessment Study (FHWA Grant) - https://www.fhwa.dot.gov/environment/sustainability/resilience/pilots/2013-2015_pilots/

2015 NCTCOG Vulnerability Assessment Study (cont.)
Notable Findings – Heat Risks for Critical Roadways
2050 Average Temperature 2100 Average Temperature
Significant future temperature increases will accelerate pavement degradation, rutting, joint failures, and utility breaches
Urbanization growth enhances regional heat island effect which amplifies moisture losses and substructure destabilization
11
Tarrant County Dallas County
Many critical roadway segments cross the 100-year floodplain and/or exist in flood-prone, poorly drained, or densely impervious areas
Additional data required (elevation, design, event detection/response plans, mitigation effects, etc.) to define overall vulnerability over time

Notable Findings – Flood Risks for Critical Roadways
12
Expanding Asset Optimization Efforts Incorporation with Hazard Mitigation Planning Efforts
Emergency Preparedness Coordination: Greater inclusion of transportation considerations
within official city/county hazard mitigation plans Pursuit of ATCMTD Grant for Regional Data &
Communications Hub building from 511DFW, Waze, and other architecture/distribution platforms
Texas State Flood Assessment (2018): Comprehensive review of existing programs, risks,
and needs for floodplain management/mitigation Report to include statewide inventory of
vulnerable transportation infrastructure
Flood Warning System Integration: Need for dense/consistent network of detection/
communication equipment across agencies Collaborative Adaptive Sensing of the Atmosphere
(CASA) Urban Test Bed Grapevine (FM 2499)

Expanding Asset Optimization Efforts (cont.)
Promotion and Integration of Green Infrastructure
Green Infrastructure enables livability, sustainability, & asset optimization linkages: Reduced overall costs Reduced urban heat stress Improved air quality and public health Increased bicycle/pedestrian safety Reduced depletion of energy resources Decreased erosion and flash flood risks Improved water quality and recharge Reduced waste and natural resource consumption Improved aesthetics/place-making and economic
development potential
Results in improved primary functions for transportation while simultaneously mitigating negative environmental impacts
14
Expanding Asset Optimization Efforts (cont.)
Identifying Local Needs and Delivering Critical Services
North Texas SHARE Program: Determine needs and solutions through
collaboration and cooperative purchasing programs through procured private vendors
Pavement Analysis Services (started in 2016): Choice of four highly-qualified vendors Continually mobile to reduce equipment fees
and allows bulk-level purchasing efficiency Services include digital image collection, ADA
ramp location/configuration, PCI scoring and analysis, budget estimates, and training
Public Works Construction Standards: NCTCOG Public Works Council (PWC) product Increased asset/storm water management
emphasis and consistency in 5th Edition (2017)

Expanding Asset Optimization Efforts (cont.)
Infrastructure, Land Use, and Sustainability Management
Transportation integrated Stormwater Management (TriSWM): Incorporate effective, environmentally sensitive,
and uniform stormwater management practices within transportation project development and lifecycle processes
Strategies to aid public/private sectors to: Design/maintain roads mindful of drainage impacts Address/mitigate adverse runoff impacts from
development and roads to improve system resiliency
Sustainable Public Rights of Way (SPROW): Provide support and technical expertise on best
practices to improve infrastructure sustainability Balances natural, aesthetic, and cultural resources,
as well as community and transportation needs

16
State DOT Transportation Asset Management Plans (TAMP): Establishment of National Highway System (NHS) pavement/bridge performance
targets may affect local-level expenditures for a variety of transportation projects NCTCOG will coordinate with local governments to determine potential effects on
all Federal-aid eligible roadways
TransFACTS Database and GIS linear referencing: Determine capabilities to link Asset Optimization project information with State
TAMP and municipal asset data within a regional database hub (TransFACTS) Ability to map/analyze conditions, needs, potential projects and performance
effects for all roadway links contained within the regional travel demand model
Expanded Green Infrastructure and vulnerability/resiliency initiatives: Integrate NCTCOG policy committee education/action with transportation
providers and local governments to improve system adaptability and sustainability Pursue local partnerships within existing University Partnership Program as a
second phase to the 2015 Vulnerability Assessment Study over an expanded area
