I'm developing a thesis proposal right now and I'm interested in the areas of FBC, design guidelines, and other regulatory approaches to urban design. I'm considering different ways to approach the topic, but I thought I'd ask you guys as practicing planners what sort of topics or issues you've come across in your practice that you think might be helped by some thorough research on best practices, innovative solutions, etc. I'd like whatever I do my research on to be something of application to planning practice, not another thesis which finds its best use propping open a door somewhere.

Any thoughts?
