San Francisco's Abundant Developable Land Supply

The San Francisco Bay Area (home of the San Francisco and San Jose metropolitan areas), which has often been cited as a place where natural barriers have left little land for development. This is an impression easily obtained observing the fairly narrow strips of urbanization on both sides of San Francisco Bay, hemmed in by hills.

However the Bay Area’s urbanization long ago leapt over the most important water bodies and then the Berkeley Hills to the east. Not only is the San Francisco Bay Area CSA high density, but it is also spatially small. In 2016, the San Francisco built-up urban area was only the 23rd largest in land area in the world. New York, the world's largest built-up urban area in geographical expanse is more than four times as large.

There is plenty of developable land in the San Francisco Bay Area. Data in a 1997 state analysis indicated that another 1,500 to 4,300 square miles (3,900 to 11,000 square kilometers) could be developed in the Bay Area CSA. The lower bound assumed no farmland conversion and stringent environmental regulation. The report also found that in recent years, residential development had become marginally denser, yet not incompatible with the detached housing remains the preference in California (Figure). The state has more than enough developable land for future housing needs.

Updating the data to account for the development that occurred through 2010, the developable land supply could support an urbanization of between 18 million and 37 million population, well above the 2010 urban population (Note on Method). At the most, there is capacity to accommodate the population of Tokyo – Yokohama, the world’s largest urban area. At a minimum, use of the available land would catapult the Bay Area CSA ahead of the Los Angeles-Riverside CSA, more than double its present population.

Of course, the Bay Area is simply not growing fast enough to reach even the lower population figure any time soon. Even with its slower growth, however, the competitive market for land no longer works, in large measure because of land use regulation. The San Jose metropolitan area has the fifth worst housing affordability in the Demographia International Housing Affordability Survey with a median multiple of 9.6 (median house price divided by median household income) and the San Francisco metropolitan area is 7th worst, with a median multiple of 9.2. Before the evolution toward urban containment policies began, the median multiples in these metropolitan areas (and virtually all in the United States) were around 3.0 or less.

The decades old Bay Area housing affordability crisis, and that of other urban containment metropolitan areas that are now seriously unaffordable (median multiples over 5.0) seeking to force higher densities, is more the result of policy than nature.

Note on Method: Some of the CSA urban population is not in the continuous urbanization of San Francisco-San Jose built-up urban area, such as in the Santa Rosa, Stockton and Santa Cruz urban areas. This analysis is based on data from the California Department of Housing and Community Development and the U.S. Census Bureau. It is based on an estimate of additional development occurring from 1996 to 2010 and the land remaining after deduction of recently developed land. The population capacity assumes the “marginally higher” densities used by the California Department of Housing and Community Development, which it notes would not require substantial changes in the “current form of housing development” (1997).

Our Quiz Challenges You to Spot Some of Your Favourite Cities

At ParcelHero, we’ve gotten to know cities all over the world. In order to share some of our favourites, we’ve put together a fiendish quiz called CurioCities, which features a hundred cities from around the world. You’d be forgiven for thinking that doesn’t sound all that exciting, which is why we put our own twist on it.

Each city in our quiz is shown off as a picture – but not a photo of the place. Instead you’ll have to think laterally and say what you see in order to work out what we’re getting at. How do you know which cities to guess? Well, with one exception we’ve picked from cities that have more than 100,000 occupants, so you can narrow things down for yourselves by looking for the biggest cities first.

To give you an idea of what we mean, let’s take Glasgow for example. It doesn’t feature on our quiz, but if it did, it might be represented by a glass on top of a traffic light, with a green light showing. One down, ninety-nine more to go!

If you’re one of the lucky few who can work out all 100 of our fiendish clues, you’ll earn your place on our illustrious 100 Club. With so difficult a quiz to work through, you’ll be in exclusive company. We here in the office haven’t even managed it without taking a peek at the answers.

Interested? Why not take a trip over to Curiocities.parcelhero.com and check it out. You can save your progress and ask for help from your social media pals, so your lunch breaks are sorted for the next few days at the very least.

Do you think you can make it to the 100 Club?

Infinite Suburbia

The suburbs of the future are almost here. Contrary to mass media's belief, many millennials are choosing to live in the suburbs, especially as they get older. Younger millennials, from 25 to 29 years old, are about a quarter more likely to move from the city to the suburbs as vice versa. Older millennials are more than twice as likely. Millennials are looking for places they can afford a home, which they are more likely to find in suburbia. However, this generation is looking for a new type of landscape, one that is smart, efficient, and sustainable.

Read about what these new suburban developments will look like in Alan Berger's New York Times piece here.

Texas Way of Urbanism

Texas cities may well be the cutting edge of American urban life. Here are two videos by Amanda Horvath that reflect the reporting done in the recent Texas Way of Urbanism report from the Center for Opportunity Urbanism.

One of these videos deals with San Antonio, the other Austin.

You Can Grow Your Own Way

A confluence of potent forces is creating an era of localism and decentralization across the planet making local decision-making and action more important than ever before. This is particularly true in the economic realm, where cities and regions must take full advantage of their unique combination of resources, culture, infrastructure, core competencies in industry and agriculture and the skills of entrepreneurs and workers.   

There is no single formula for success for any place in the 21st century. Your economic strategy may need a shot in the arm (or a kick in the butt), a total remodel or perhaps it needs to be meaningfully modernized.

The NewGeography Economic Opportunity & Growth Forum is a one-day strategy event that helps leaders, innovators and entrepreneurs develop strategies for grappling with challenges and seizing opportunities that will propel local growth.

The one-day Forum addresses the basic fundamentals to propel growth including policies that stress essential physical infrastructure, investments in basic and skill-oriented education, and a favorable business environment that facilitates free enterprise and entrepreneurship.

Joel Kotkin, an internationally recognized authority on economic and social trends and, a founder and Executive Editor of NewGeography.com, begins each forum with a high-level look at consequential trends and circumstances that affect local and regional growth. This is followed by an economic assessment of the local and regional economy and subsequent panel discussions involving key local leaders in business, government, education and the civic sectors.

Each Forum culminates in afternoon strategy sessions that lead to the identification of priorities where enhanced collaboration is needed and action steps are identified for building support and mobilizing resources and talents to put your city or region on a solid growth trajectory.

NewGeography anticipates doing only two to three Forums in the remainder of 2017 so contact us at your earliest convenience to get the ball moving. Download this pdf for more information about how to bring the forum to your community.
