Finding Success in the 21st-Century Community
Communities must rethink their business model to successfully respond to major stressors: (1) rapid population growth and urbanization; (2) declining municipal resources; and (3) growing risk and uncertainty caused by climate change.
Growing Populations Flock to Cities
More people live in cities – whether in the urban core or surrounding suburbs – than in rural areas. In 2007, for the first time in history, the world’s urban population exceeded its rural population.
As of 2014, 54% of the world’s population lived in urban areas, up dramatically from just 30% in 1950. By 2050, 66% of the world’s population is projected to be urban. In the United States, that percentage is even larger – 83% of Americans are urban dwellers.
The takeaway: We’re going to see an increased demand in all areas of urban infrastructure and public services, including intertwined impacts on education, transportation, housing, water and public health. Accommodating this growth will require dramatic shifts in the way we plan communities, and much of those efforts will take place at the local level.
Cities Struggle to Meet Growing Demands
Local governments play a key role in responding to growing urbanization challenges through land-use planning, community services, climate and energy initiatives, and infrastructure decisions, ranging from street repairs to stormwater and forest management.
But their ability to respond at a level commensurate with the need is inhibited:
- State and federal aid to California cities is declining, down from an average of 21% of a city’s budget in 1974–75 to 10% today.
- The sales tax base is declining, due to a shift toward a service-oriented economy and increasing online retail sales.
- The capacity for cities to impose taxes and fees that cities are limited by Proposition 13 and Proposition 218.
- The state’s population growth rate is higher in cities, putting even more stress on already strained urban infrastructure.
- Cities must respond to the public demand for a greater array of services (high tech, cable, transit, etc.), which bring additional costs and new challenges.
- Spending for public-safety services is up.
- Infrastructure improvements and maintenance (often already long deferred) are lagging.
Despite these fiscal obstacles, we can and must respond to growing urbanization. We have to act in a way that reduces pollution and increases community resilience – starting now. Communities must be much more creative, and every public dollar spent must achieve multiple goals and leverage additional resources.
Climate Change: Costly Threat or Economic Opportunity?
Climate change has been called the biggest threat of our generation – posing significant risks not just to our health, but our economic prosperity too. A 2015 Citigroup report estimated that the estimated cost of inaction on climate change is set at $192 trillion over the next 25 years. The “action” scenario costs slightly less – $190.2 trillion – thanks to the rapidly falling cost of renewables and energy-efficiency improvements.
As the environmental and economic evidence mounts, the climate-response message is taking root. A landmark climate agreement was signed by 195 nations in December 2015 at the Conference of Paris (COP21). Each nation will submit and report on emissions targets with the goal of cutting greenhouse gas emissions to a level that will limit the global average temperature to a rise “well below” 2C (3.6F) – a level deemed to be dangerous to the point of threatening life on Earth.
At the nexus of meeting the needs of growing cities while addressing climate-change impacts are transportation and energy. The electricity sector makes up 31% and transportation 27% of greenhouse gas emissions.
However, when you consider that the primary source of greenhouse gas emissions in the industry, commercial and residential sectors also come from fossil fuels burned for energy or heat, you can see that innovations in powering our transportation and buildings will have a significant impact on the intersection of growing urbanization and emerging environmental challenges.
Communities and corporations who understand this significant connection recognize there is a tremendous opportunity to be at the forefront of new clean/green economy initiatives.
Private Innovation Finds Public Responsibility: Entrepreneurial Communities Take Notice
Transportation: The Market for Shared Mobility, Shared Community Benefits
In transportation, companies have found large untapped markets and are advancing initiatives with substantial fiscal success and the potential for significant community and environmental benefits.
For example, Uber is running a $40-billion organization without any cars at a time when transportation funding (in real dollars) is at an all-time low.
Car-share companies are picking up on changing preferences, and using technology to connect people to their destinations, to transit (by filling first-mile/last-mile needs) and to other riders through carpool services.
The number of car-share vehicles have risen in the U.S. from less than 700 in 2003 to more than 19,000 in 2014 (Shaheen and Cohen, 2014) – a nearly three-fold jump.
While astonishing, this should be now surprise given the pent-up demand from one of our largest generations. Millennials have the lowest percentage of people who like driving than any other generation: 83% of Millennials like walking, and they also have a much higher percentage of transit use (40% took transit last month).
A 2008 survey on carsharing in North America (Martin et al. 2010) found:
- An annual VMT reduction of 27-43%.
- A 34-41% annual reduction of greenhouse gas emissions per household.
- S. households saved $154-$435 monthly per capita after joining carshare.
- More users increased their overall public transit and non-motorized modal use (including bus, rail, walking and carpooling) than decreased it.
Ingenuity in the transportation sector is critical. Because our growing population is travelling on roads in severe need of repair, we need to implement solutions to get more people out of cars and assure cars on the road are carrying more passengers. To put one price tag on the problem: It would take and estimated $533 billion to expand roadways and relieve severe congestion in U.S. urban areas.
Currently, 80% of seats on the road are empty, and 5.5 billion hours are wasted by Americans each year due to road congestion. Fewer than 50% live within a one-quarter mile walking distance of a transit stop.
Expanding alternative transportation and ridesharing strategies can increase access to existing transit and help alleviate traffic congestion.
More than 20% of their rides in the San Francisco Bay Area start or end near a BART or Caltrain stop, according to Lyft. Lyft Line (their carpool service) makes up more than 50% of its rides in San Francisco; and 90% of Lyft rides have someone else taking the same trip within five minutes (highlighting a potential for increased carpooling).
Lyft has been operating their Lyft Line carpool service for only one year in SF, and 50% of their rides are carpool. They are at about 3% of current mode share and have grown 1% in the last year. Twenty percent of Bay Area Lyft rides start or end near major transit lines.
At a time when funding to operate and maintain (let alone expand) existing roadways and transit lines is diminishing, local governments should look to shared-mobility platforms as an opportunity to leverage private-sector investment and a growing market to achieve community goals.
Energy: PACE Brings New Energy to Retrofitting Old Buildings
Growing populations, paired with increased temperatures from climate change, will create major stresses on our electricity grid and result in increased greenhouse gas emissions if we don’t make significant investment in energy efficiency and renewable energy.
Property Assessed Clean Energy (PACE) can help achieve climate goals by providing financing for energy-efficiency, renewable-energy and water-conservation improvements that is repaid (through the energy savings) on a building owner’s property tax bill. Communities invest their own funds strategically by creating PACE programs or partner with private PACE providers to fund energy projects in their communities without the upfront cost or liability.
With approximately $200 million in commercial projects and more than $1.2 billion in residential projects funded, PACE has already had a substantial impact on greenhouse gas emissions, energy and water consumption, and indoor air quality. PACE is one of the most effective ways to finance solar and energy-efficiency improvements needed to achieve greenhouse gas reduction targets and renewable portfolio standards.
In Connecticut, for example, a $1.5 million solar PV project financed with PACE led to a greenhouse gas reduction of over 3,000 MT — equivalent to taking 632 cars off the road.
In California alone, HERO – the state’s largest PACE provider – is in over 367 cities and available to more than 75% of California’s housing units. HERO has helped to create more than 7,500 jobs, funded more than 38,000 residential projects, and provided more than $875 million in financing to homeowners.
Vision for Resilient 21st-Century Communities
Necessity breeds innovation. Many communities are now at a point where addressing growing populations and acting on climate change are inescapable, with opportunities inextricably linked.
These solutions can’t focus solely on what we need to give up, however. We want to end up with something better. We want to fight for something, not just against something. We need a vision that’s worth working toward, rather than an approach aimed at simply holding back negative impacts. By establishing new partnerships across jurisdictions and between the public and private sectors, local governments can optimize community benefits from limited resources – from shared mobility to zero-net energy buildings. We can, and must, plan for a tomorrow that’s worth working for together today.

Earlier in my career I learned the hard way that you can never ratchet expectations above the baseline you set in those critical early moments of a project or initiative. People and organizations very quickly settle into the level of performance that they deem acceptable to you.
