One of Jane Jacobs’ key points in her works tells about the need for diversity in neighborhoods: choices and options in housing, jobs, natural and gathering spaces, and entertainment. As lives and lifestyles change, people aren’t forced to move or move out. Urbanophile touched on that in part two of “Building Suburbs That Last.”
This should sound familiar to you since it is exactly how Jane Jacobs described a healthy city neighborhood. She says it better than I ever could: â€œFlourishing diversity anywhere in a city means the mingling of high-yield, middling-yield, low-yield and no yield enterprises.â€ And, â€œTime makes the high building costs of one generation the bargains of a following generation. Time pays off original capital costs, and this depreciation can be reflected in the yields required from a building. Time makes certain structures obsolete for some enterprises, and they become available to others.â€

I don’t believe that Jane’s discussions will convince any banker, economist or developer. For those arguments, you’ll have to refer to the rest of Aaron’s article on how smart, commercial land use development occurs in order to create sustainable suburbs. You should refer to paragraphs like:
If you having nothing but high value buildings, no one but national chains can afford to invest. If you have nothing but low value buildings, no one wants to. It is important to have a mixture of buildings, supporting a mixture of uses, mixture of high, medium and lower values uses, and both national chains (which bring much good with them) and indigenous business. It is this diversity that again helps to mitigate against the failure of any one element. And also provides room for the local business that is both committed to the town and a source of at least some independent economic life.
Where else does diversity give an advantage?
About Steven Can Plan
I started this blog in 2007 as the writing assignment for an introductory urban planning class at UIC. It's about cities (mainly Chicago), GIS oftentimes, and transportation (mainly bicycling). Learn more about me, Steven Vance. I also write for Streetsblog Chicago.
Steven Can Plan is hosted on Dreamhost.
Chicago Bike Map App
The Chicago Bike Map app is a bike and street map stored entirely in your iOS device – no data connection required. The map is designed to look much like the City of Chicago's official printed and online bike map. The app works on iPhone, iPod touch, and iPad.
Highly Recommended Bike Products
So far I haven't had a flat with this tire. I've used Continental Gatorskin and Panaracer T-Serv, both of which have had flats (same Chicago streets). The Gatorskin has less tread than both, and wears to a slick surface faster.
I've used this pannier to carry groceries, books, my laptop, clothing, anything. I like it because it's stylish (but also "normal" looking at the same time), stands up on its own, is extremely durable, and has the most universal attachment system: two hooks.
Bells can be quite useful, especially to tell people in front that you're passing them. I like the ding-dong bell the best. It makes a solid DING and then DONG on the spring's return.
Traffic: Why We Drive the Way We Do (and What It Says About Us) by Tom Vanderbilt
As someone who doesn't like driving, but believes that cars can be efficient in moving groups of people and goods, this is my favorite book.
Sustainable Transportation Planning: Tools for Creating Vibrant, Healthy, and Resilient Communities (Wiley Series in Sustainable Design) by Jeffrey Tumlin
I was sent a review copy. I'm really excited to open it up and start reading because I've been disappointed with textbooks in the past that don't focus on bicycle and pedestrian planning.
Making Maps: A Visual Guide to Map Design for GIS by John Krygier PhD, Denis Wood PhD
If you are going to make a map, whether it be hand drawn or digital, you should really give this book a read. Then read it every time you make a map. It will help make sure your maps are laid out sensibly, in a way that others can easily read, and that it doesn't include fluff or unnecessary data.
