THE PERIL: URBAN FORM

Superblocks dominate urban development

Sprawling development and ever expanding city boundaries

RISKS LOCKING IN BAD URBAN FORM

THE PERIL: TRANSPORT

Urban infrastructure revolves around the car

Highways perceived as a mobility solution

THE HUMAN SCALE IS LOST

THE DIFFERENCE OF GOOD PLANNING

BARCELONA HAS ROUGHLY THE SAME POPULATION AS ATLANTA, BUT TAKES UP ONE-TENTH THE LAND AREA AND EMITS 5X FEWER TRANSPORT CARBON EMISSIONS

What are the minimum requirements to building a great city?

An urban growth boundary is set around a city to contain urban sprawl and preserve

the land outside of the boundary

Mixed-use development intermingles residential, commercial, recreational, and cultural space,

guaranteeing amenities and services are easily accessible

Small blocks create a dense mesh of narrower, pedestrian-friendly streets and paths, facilitating street life and the shift away from car use

Attractive public spaces create a sense of community and neighborhood identity, while enhancing the city’s

economic vitality and environmental resiliency.

Liuyun Xiaoqu, China

The world’s most attractive cities prioritize transportation development at the human scale Dense networks of walking and biking paths allow for shorter, more efficient, and more pleasant commutes.

Bus-rapid transit (BRT) moves people around cities quickly and safely

Public transit must be a first-class option for transportation


Guangzhou before and after bus rapid transit

Public transit must be a first-class option for transportation

Elements of good bus rapid transit (BRT): Dedicated bus lanes occupying the center of the roadway Stations that are level to bus height and collect fare prior to boarding

An advanced country is not one where the poor move about in cars, rather it’s where even the rich use public transportation. - Enrique Peñalosa, Mayor of Bogotá


Car control improves space efficiency on streets

Buses Bikes Cars

BEFORE

AFTER


Parking and driving restrictions, safe options for biking and walking, and top-notch public transit help to limit car use in cities


Green buildings employ a variety of efficiency techniques to minimize their energy and resource consumption

Shenzhen’s IBR Building


Cost premiums for green buildings are decreasing, while

property values are increasing

Seattle’s Bullitt Center

Green buildings employ a variety of efficiency techniques to minimize their energy and resource consumption


Solar hot water

Rooftop solar PV systems

Falling costs and increasing efficiency rates make renewable energy resources more viable options


TODAY: District energy systems produce steam, hot water, or chilled water that is piped to individual buildings for heating and cooling

Traditional district heating systems avoid buildings’ need for furnaces, boilers, air chillers, etc.


TOMORROW: District energy systems will produce energy at a more decentralized or localized level

Microgrids offer energy security and stability,

while helping increase the adoption of

renewable energy

San Francisco’s Recology waste management company diverts 80

percent of waste from landfill

Waste management practices aim to reduce, reuse, recycle, and recover as much waste as possible.

More efficient water consumption reduces energy usage needed to treat, move, or heat water
