Challenges due to Urbanization • Stratified growth and increasing inequality
• Environmental concerns (degradation/loss of natural assets, air/water pollution, energy demand, climate change, solid and liquid waste, …)
• Cost of urban services (Housing, Health, Schooling, etc.)
• Disutility of critical infrastructures and their services
• Cost of maintaining the deteriorating built environment
• Increasing complexity of
natural and man-caused
hazards due to climate change; population growth and
accelerating urbanization
• Challenges to effective and good governance due to multiple
levels of government,
overlapping ownership and
interdependent service
providers with different org
cultures

Urban PlanningIn 1898, Sir Ebenezer Howard started the garden-city movement
in London. United States held its first urban planning conference
in New York City, bringing together architects, public health
officials, and social workers.
Urban planning education continued to evolve from the
interactions of civil engineering, architecture, medicine, public
health, and sociology. By the 1960s, urban planning included
social sciences and economics as well. Today, over 70 US
Programs offer accredited degrees.
Today urban planning and design is evolving into urban science,
including urban informatics and smart-city technologies, GIS,
urban modeling and simulation, and mobility. Solutions to noise,
building energy, transportation, resilience, and hazards risks and
emergency response are investigated.
Foresight Future of Cities (2013-17) Project
UK Government Office for ScienceThe project team visited 20 cities to understand and integrate the work of – think-tanks, universities, research centers and lobby groups.
Municipal Engineering – Deals with municipal infrastructure and designs, constructs and maintains pavements, water supply networks, sewers, street lighting, municipal solid waste management, public parks,
bicycle paths, etc. working closely with Urban Planners.

The Vision for Civil Engineering By 2025 (ASCE) civil engineers serve competently, collaboratively, and ethically as master:
• planners, designers, constructors, and operators of society’s economic and social engine--the built environment;
• stewards of the natural environment and its resources;
• innovators and integrators of ideas and technology across the public, private, and academic sectors;
• managers of risk and uncertainty caused by natural events, accidents, and other threats; and
• leaders in discussions and decisions shaping public environmental and infrastructure policy.
URBAN INFRASTRUCTURES - issues
1. Culture of ownership and organizational accountability; Process vs Performance based!
2. Finance and lifecycle revenue mechanisms
3. Project delivery mechanisms and lifecycle costs
4. Quality and robustness metrics for services
5. X-Sector Coordination for Asset Management
6. Innovative paradigms & technology
7. Managing the intersections & interdependencybetween infrastructures and services
8. Managing multi-hazards Risks, Emergencies and Resilience

Transforming the Practice of Engineering of
Large Complex Systems
Inter-Agency Working Group
on the Engineering of Complex Systems
Working Group included Directors fromNSF, DOD, DOE, NASA, NIST & US Army Corps of Engineers
Approved for public release by DOPSR on 11/27/2013http://www.acq.osd.mil/se/docs/IAWG-Position-Paper_DoD_12DEC2013.pdf
The complexity of engineered systems has swelled in the last several
decades, and this trend is likely to continue for the foreseeable future.
While projects are becoming more complex, current engineering
practice has largely evolved from a top-down approach that is the
legacy of past successes. A fundamental rethinking of engineering
methodologies is urgently needed if our nation is to ensure that the
large complex systems critical to our national security, economy, and
quality of life are resilient in the face of natural disasters, creative
adversaries, and an unforeseeable future.

HOW TO LEVERAGE DESIGN THINKINGFOR LIVABLE SUSTAINABLE RESILIENT URBAN REGIONS
IRVING WLADAWSKY-BERGER Nov 4, 2016 Wall Street Journal http://on.wsj.com/2eH8Crw
• Design is no longer just for physical objects.
Design thinking is now being applied to abstract
entities, such as systems and services, as well as
to devise strategies, manage change and solve
complex problems.
• By now, it’s been a generally accepted that design
thinking can be applied to just about all disciplines
and professions. One cannot design what one
cannot imagine; therefore, enhancing creativity is
an important precursor to effective design.
• Desirability is central to Design Thinking.
HAZARDS and INFRASTRUCTURE DISUTILITY RISK
Natural Hazards Manmade HazardsATMOSPHERIC: Hail, Hurricane, Tornado,Lightning, Storm Surge, Flood/Flash Flood
TERRORISM: Blast, Fire, Explosion, Implosion, Chem-Bio Agents, Poison Gas, Gunfire , Cyber
SEISMIC: Fault rupture, Ground shaking, Falling Debris, Fires, Liquefaction, Tsunami
POLITICAL: Decision-making driven mainly by politics w/o Impacts, Utility and Feasibility
GEO: Avalanche, Expansive soils,Landslides, Mudslides, Rock falls, Subsidence, Slope Failures, Sinkholes
POLICY: A Lack of Policy (for innovation, accountability, responsibility), Bureaucracy, disconnected PLANNING vs EXECUTION
HYDROLOGIC: Coastal flooding, River flooding, Erosion and sedimentation, Desertification, Salinization, Drought, Ice

The NSF Cyber-Physical Systems Group will coordinate efforts among Federal agency and with public-private partnerships for smart and connected communities. The relevant agency activities include:
• Performing foundational research and accelerating innovation and transition in scalable and replicable smart city solutions
• Applying advanced cyber-physical systems concepts, coupled with sociotechnical system understanding, to integrate city-scale IT and physical infrastructures
• Enabling replicable smart city solutions that provide powerful new safe, reliable, sustainable, resilient, secure, privacy-enhancing, and cost-saving platforms and services
• Promoting discovery, innovation, and entrepreneurship in smart city technologies
• Facilitating the ability of communities to apply cyber-physical systems concepts to solutions that make them more livable, workable, safe, and sustainable and that support an informed and engaged populace
