Watch Cabarrus sprawl! And Catawba too!

OK, I'll admit my bias. I thought Union County would be the biggest sprawl-zone in the Charlotte region. Turns out the honor may go to Lincoln County. (It depends on how you're measuring, of course.) Here's why I say that. As I was adding the link to my post about mountain development, I spotted something interesting on the UNCC Urban Institute website: an interactive set of maps of the counties in the Charlotte region that depict visually the development from 1976 to 2010, and projecting forward.

So I did some exploring. I started with Union County, home to Weddington, Marvin, Indian Trail and numerous other one-time crossroads just over the Mecklenburg line that have become full-fledged towns. Here's the link. (Click on the option for interactive map.) A county that in 1976 was almost completely undeveloped (shown in green) by 2010 was fully a third covered in development. From 1976 to 2006 its population increased 171 percent, but its land area that was developed increased 878 percent. What that means, of course, is that the land was developed in a low-density pattern. And here we go again, a tidbit for fiscal conservatives: Multiple studies show lower-density, spread-out development makes delivering of government services (police/fire protection, streets, water/sewer lines and so on) far more expensive per person than a more tightly knit developmental form – you know, the way things looked before about 1970.

But then I started looking at some of the other counties in the region. Unfortunately, there doesn't seem to be a Mecklenburg interactive map. That one would have been eye-popping, I expect. (Update 1:55 p.m. Thursday: Thanks for the help, commenters. Here's the link to the Mecklenburg map, which was working when I checked it at 1:53 p.m. Thursday. And yep, it's eye-popping. Interesting also, besides seeing the green disappear, to see the "protected lands" increase.)

But of those I checked (Anson, Iredell, Lincoln, Catawba, Cabarrus and York) Catawba probably had the most visibly dramatic change. Cabarrus was dramatic as well.

But this Lincoln County stat blew me away: While its population increased 86.2 percent from 1976 to 2006 its developed land area increased by 1,450 percent.
