Planning Infrastructure for Sustainable Communities (cont.)

3.6

1. Serve future populations

2. Meet identified public service needs, which may be diverse

3. Remain functional

4. Be supported by continuing, reliable financial resources

5. Lie lightly on the land

What does this mean? Ensuring that land (and related air, materials and water

resources) can accommodate human habitats, support natural ecosystems, and adapt to climate

change

Why are we repeating it? Because it’s important

To meet the needs for economic, societal, and environmental sustainability by: Meeting the ongoing needs for natural resources,

industrial products, energy, food, transportation, shelter and effective waste management, and at the same time protect and improve environmental quality

Ensuring resiliency by designing infrastructure with sustainable practices to protect the natural environment and withstand both natural and man-made hazards, and mitigate and adapt to climate change, to ensure that future generations can use and enjoy what we build today

Sustainable Infrastructure Goals

3.11

Planning, design, construction, operation and maintenance of infrastructure (includes buildings) is about 1/8 of the GDP

President Franklin Roosevelt’s New Deal Program in the 1930s

Sustainable Infrastructure and Economy

3.12

National Park Service

Goals for Providing Sustainable Economic Opportunities: Encourage “green” industries and “green”

jobs that lie “light on the land” Wind farms, solar power, ocean power, other

local power (geothermal, biomass, small wind, solar, landfill gas, etc.)

Energy conservation industries such as building insulation, energy efficient windows and doors

Intelligent transportation systems (ITS) Recreation and tourism industries

Sustainable Infrastructure and Economy

3.13USGS

Sustainable Economic Opportunities Goals (cont.): Make the most of local industries that require less transportation

costs, energy, and time Locally grown agricultural products Other local raw materials and natural resources that can

be turned into finished products locally (wood products, e.g.)

Work with “heavy impact” indus- tries to mitigate adverse impacts Agriculture Mining Off-shore oil drilling Power Generation

Sustainable Infrastructure and Economy

3.14

Coal Power Plant, Baltimore. Joanna Woerner, IAN

Until late 20th century, community building and economic development focused on suburban development, amplifying social and economic inequalities Infrastructure planning siting decisions areas with low

land values, floodplains, close proximity to power plants, landfills disproportionately affecting the poor

Least Cost Imperative = Social and physical rehabilitation costs were ignored

Certain communities not engaged

Social Equity and Health

3.15

Disadvantaged or underrepresented groups include: Low income citizens Elderly Ethnic minorities Social minorities Handicapped Children Future generations

Social Equity and Health

3.16

Rooftop Garden

Health Concerns Health Air, water, and vector‐borne

diseases Obesity Malnutrition Physical fitness Quality of life, emotional wellbeing

Social Equity and Health

3.17

San Mateo, CA

Goals to Improve Social Equity and Health: Transform urban vacant lots into park-like gardens that

catch stormwater runoff and improve the social and economic fabric of neighborhoods historically lacking green space

Address health disparities by advancing environmental justice (i.e., fair and equal treatment to all) and improving community social interaction

Improve access and participation in government Improve access to basic services

Social Equity and Health

3.18

Pollution by human habitation is occurring faster than natural abilities to regenerate, resulting in a massive loss of benefits: Fish and fishing industries and wildlife habitats

as abundant sources of food Clean water bodies for water supply as

well as healthy habitats for fish, wildlife, and/or recreation

Raw materials for fuel, paper/lumber, and construction aggregate materials

Clean air

Environmental Sustainability

3.19

Factors contributing to decline:1. Urbanization pollution from sewage & runoff

3.22

Effective, Efficient, Sustainable Transportation: Effective:

1. Personal mobility, accessibility, & safety are well served

2. Goods moved in a timely, reliable manner

3. Economic development needs are met

4. Human social, cultural, and recreational needs are met

Efficient: Transportation infrastructure and services are

affordable, and life cycle costs are optimized

Sustainable: Air and water quality, and wetland footprints are as small as possible,

designed for the long-term, socially equitable, and with secured funding

Infrastructure System: Transportation

3.23

Local government planning authorities: Zoning, subdivision, tree cutting/grading/building permits, issue permits, public water/sewer hook-ups which are essential

Local public works agencies: Local departments, transit agencies, local social services agencies

Regional organizations: Federally required metropolitan planning organizations (MPOs), metropolitan air quality boards, Regional Planning Organizations (RPOs), Areawide Agencies on the Aging (AAAs)

State Agencies: State DOTs, specialized agencies, state legislature

Multi-State Transportation Corridor Coalitions: NAFTA

Federal Government: Grant-makers, Amtrak, Maritime

Transportation Players: A Complex Picture

3.24

Single-mode Funding available for intermodal integration, but there is little flexibility on how funds are spent; MPOs and Corridor Coalitions who help to coordinate funds are not fully effective

Federal Transport Funding is lacking

Environmentally Sustainable Transportation Systems take time to build

Federal Leadership is limited for rail systems and multi-state corridors, but there are new initiatives for planning high-speed rail and freight systems

Performance Management measures to track progress are limited, but there are new efforts to improve these measures and their use

Transportation: Sustainability Challenges

3.27

The world is reliant upon adequate, economical, healthy, safe, and reliable energy

In addition to aesthetics, these are the socially sustainable

requirements for energy infrastructure

Infrastructure Systems: Energy

3.28

1992 Energy Policy Act: Markets allowed to develop across state boundaries, giving freedom to choose

Demand-supply model: Utilities provide electricity wherever it is required, with costs of new infrastructure shared by all of the utility’s customers Limited consumer incentive to reduce energy use, since increased

use covers capital investments Reducing use, however, allows utilities to postpone building new

facilities

Energy Infrastructure: Current Practices

3.29

Energy: Sustainability Challenges

3.30

Reliability: Provide energy when and where it is required for

quality of life, economic activity, and safety Increase resilience as damaging storms become

more severe and frequent Bring utility electricity delivery systems into the 21st

century (smart grids)

Efficiency: Maximize the useful energy from a given amount of

resource

Economy: Provide energy at an affordable cost

Environmental Impacts: Lead and mercury contamination from coal

combustion Carbon emissions from fossil fuel burning Pollution in river runoff from mining Toxic pollution from nuclear waste

Environmental Miscounting Energy costs don’t account for cost of restoring

the environment or eliminating polluted byproducts

Dependence on Imported Fuel

Energy: Sustainability Challenges

3.31

Waste Heat, methane, and greenhouse gas recovery

programs are becoming drivers in energy policy Hazardous waste from newer technologies

Chlorofluorocarbons (CFCs), nuclear

Systems Preservation to increase design life

Passive Energy Systems to reduce or eliminate demand for energy generation

Energy: Sustainability Challenges

3.32

Energy Efficiency Can Reduce Demand Largest, most economical energy source Planning practices:

3.36

Sustainability Challenge: >70% of all water use worldwide is for

irrigation, and attempts to limit irrigation can lead to limits on food production

Demand for water doubles every 21 years, while water tables are falling

Emerging Practices: Designing systems that minimize

water’s overall use and leaking Utilizing recycled water and rainwater

onsite

Infrastructure System: Water

3.37

Sustainability Challenge: Upgrades have not kept up with the pace of urbanization

facing cities, nor is planned infrastructure spending enough

Infrastructure System: Wastewater

3.38

Emerging Practices:More emphasis on alternative disposal methods

to supplement and augment traditional systemsDecrease need for extensive piping; emphasis on

local capture and treatment

Infrastructure System: Wastewater

3.39

Sustainability Challenge: Many urban systems have not kept pace with increased

demands or maintenance and repairs Combined systems still exist

Emerging Practices: Integrating LID

concepts into existing practices and regulations

Infrastructure System: Stormwater

3.40

Emerging Practices: Concepts such as “waste-to-energy,” “zero-waste industrial

complexes,” and “up-cycling” are redefining the manner in which waste is viewed and handled

Waste disposal now focuses on minimizing waste at all stages of the use of materials

Performance Measures: % of waste diverted to composting Presence of hazardous waste in stormwater and sewage effluents % of electronic waste recovered for reuse or recycling Energy expended per unit waste to transfer it to landfill

Infrastructure System: Waste Management

3.41

Evolving Infrastructure: Development of smart grids depends entirely on

communication infrastructure, a vital part of smart buildings

Utilization of technology to tweak offsite electrical use, reroute traffic, etc.

Infrastructure System: Communication

3.42

Why is innovation in infrastructure important to a community’s livelihood?

Study Question

3.43

See: References #1, 2, and 4 (end slides)

Aging infrastructure, the provision of new infrastructure for a growing population, vulnerability – all pose major infrastructure challenges

Each system’s life cycle involves planning and procurement, design and construction, performance monitoring, and renewal. For each phase, multiple research challenges exist. These include the impact of new technologies, incorporation of sustainable materials, modeling and retrofitting for deterioration effects, asset management and the impact of extreme loads, climate change and the carbon economy.

Tracking performance/measuring sustainability is important for scenario modeling, system management, and engaging the public in quantitative goal-setting

“Smarter,” sustainable infrastructure is vital for the creation of strong urban centers, as well as economic, social, and environmental wellbeing
