Here is an article that should be read by Governor Sununu which points out, among other things that:

“Density–bunching up–makes us more vulnerable to terrorist attacks. It makes us more vulnerable to novel diseases. It makes us more vulnerable to crime, invasions of privacy, and traffic accidents. It makes us waste more time in congestion. Contrary to planners’ claims, people living in dense areas also pay higher taxes.

Densities and transit‐dependence also makes us more vulnerable to natural disasters. When Hurricane Katrina hit New Orleans, 1,200 people died, mostly because New Orleans had the second‐lowest rate of auto ownership (next to New York) of any major city in the country. At the time, some urban planners had the gall to say that fewer people would have died if auto ownership rates had been even lower. In fact, a few weeks later, Hurricane Rita hit Houston, which has much higher auto ownership rates. Four million people successfully evacuated, nearly all by car, and fatalities were only a tenth of Katrina’s.”

Indeed, It’s the Density, Stupid!
