  Smart Growth  

Burglar-Friendly Neighborhoods

by Randal O'Toole

Bike paths do more than provide yuppies a chance to ride their bicycles.


Almost everyone has seen the famous film of the St. Louis housing project that was intentionally blown up in 1972, just 16 years after it was built. Though it had won several architecture awards, it and other housing projects proved to be unlivable due to high crime rates.

Randal O'Toole is senior economist with the Thoreau Institute and author of "Reforming the Forest Service."

These housing projects led architect Oscar Newman to develop a crime-prevention theory known as Defensible Space. Newman's theory, which is old hat to libertarians, is that people will defend their private property, but common areas such as parks, public courtyards, and hallways are left unprotected.

One of Newman's most important publications can be downloaded from the Department of Housing and Urban Development's website.* Yet the theory has been totally ignored by urban planners today, particularly those planners who promote so-called smart-growth planning, also known as New Urbanism.

Planners are fond of quoting Winston Churchill, who said, "We shape our buildings and afterwards our buildings shape us." The basic idea behind both Defensible Space and New Urbanism is to shape human behavior through urban design. But the goals of Defensible Space and New Urbanism are quite different: the former aims to protect residents against crime, while the latter aims to impose a "sense of community" on residents and discourage them from using the evil automobile.

The two theories make opposite recommendations about almost every major aspect of urban design (see table below). This is really not surprising given that Defensible Space is all about maximizing private property while New Urbanism aims to maximize the commons to promote a sense of community.

The theory of Defensible Space has been carried the furthest in Great Britain, where many police departments have architectural liaisons on staff to help developers design housing and other developments that will minimize crime. Developments that meet basic Defensible Space principles are certified by English police as Secured by Design, and such developments no doubt command a price premium.

Though begun in the U.S., New Urbanism has also spread to Britain, and was recently endorsed by the Deputy Prime Minister. This has stunned the police liaisons, who describe New Urbanism as "criminogenic."

The basic idea behind both Defensible Space and New Urbanism is to shape human behavior through urban design.

"Cars are isolated from owners; the public realm abuts private space; the large amount of communal green space lacks ownership, purpose, and influence; the layout is ludicrously permeable, providing offenders with complete anonymity and opportunity to wonder around, familiarizing, searching for vulnerable targets, offending and escaping," says West Yorkshire Architectural Liaison Steven Town. "At what point is a stranger's presence inappropriate, suspicious, or challengeable?" In a New Urban development, "residents quickly lose confidence, whilst offenders become ever bolder and contemptuous. The design has unintentionally taken control from residents and handed it into the hands of the anti-social."

Peter Knowles, the architectural liaison officer of the Bedfordshire Police Force, recently compared developments designed to New Urbanist standards with those designed to Secured by Design standards. The developments had about the same population densities and income levels, but variable levels of subsidized "affordable" housing.

Knowles' analysis concluded that crime was more than five times greater in the New Urban developments than in the Secured by Design developments. This included nearly eight times as many home burglaries, more than five times as many stolen cars, more than five times as many auto break-ins, and nearly four times as much criminal damage. Dealing with crime in the New Urban neighborhoods cost the police three times as much.

Knowles also found that increasing the amount of subsidized, low-income housing in a neighborhood from 20 to 30 percent increased crime in both kinds of neighborhoods. But it increased crime by 40 percent in the New Urban neighborhoods and only by 12 percent in the Secured by Design neighborhoods.

Stephen Town points to a development of 21 homes built on a cul de sac that was virtually crime free after it was built. Then planners constructed a bike path through the neighborhood to a nearby shopping center. Burglaries increased to nine times the national rate and residents described their neighborhood as "a hellhole."

American urban planners seem totally oblivious to Defensible Space principles. Numerous cities have been influenced by planners to forbid cul de sacs and large-lot developments and to promote mixed-use developments, narrow streets, and other New Urban designs. Most of these rules apply to new developments, but planners have also set their sights on reconfiguring existing developments to these standards. Cul de sacs are to be connected by pedestrian paths if not by streets, and zoning codes are being rewritten to allow mixed uses in neighborhoods that currently have just single-family dwellings.

When planners constructed a bike path through the neighborhood to a nearby shopping center, burglaries increased to nine times the national rate and residents described their neighborhood as "a hellhole."

When Peter Knowles' report was published on the Web, American New Urbanists were quick to deny that it applied here. Robert Steuteville, the editor of New Urban News, says, "[W]e are not aware of any reports of significant or elevated crime in any of the more than 200 sizable New Urban communities."

Of course, this may not mean that such crime does not exist; it may only be that New Urbanism is so politically correct that no one has yet dared report it. U.S. urban planners have shown a complete lack of interest in whether the people who live in New Urban developments really drive less, as the planners claim. It would be surprising whether any planners bothered to find out what their ideas did to local crime.

The American equivalent of Secured by Design is a program called Crime Prevention through Environmental Design (CPTED). But this program lacks the focus and research that backs up Britain's Secured by Design. Documents prepared by CPTED advocates say very little about what kind of designs will reduce crime. One CPTED newsletter even endorses New Urbanist principles without ever saying how banning cul de sacs and requiring stores in every neighborhood of 500 homes will create defensible space.

New Urban vs. Defensible Space

Even if planners pretend not to understand Defensible Space, most Americans are fully aware of the benefits cul de sacs, separated uses, and visible parking have for their security. Neighborhoods strongly resist efforts by planners to connect cul de sacs or insert bike paths or commercial uses in their midst. In Portland, new homes in neighborhoods built following New Urban designs have sold slowly, even given the huge subsidies offered by local officials smitten by planners' utopian dreams.

As one proponent of Defensible Space says, New Urbanism is "filled with religious and so-far unsubstantiated beliefs." We know that is true with respect to auto driving. One study done by New Urbanists themselves compared several urban areas and found that the one with the highest population density, most intensive transit service, and most pedestrian-friendly design also had the highest per capita driving.

In April, a new anti-New Urban group called the American Dream Coalition will hold a national conference on "Preserving the American Dream" in Portland, Ore. West Yorkshire Architectural Liaison Stephen Town will review New Urban developments in that city and describe the situation in England. Perhaps this will lead to some objective research on crime and New Urbanism in the U.S.
