I had SO forgotten this thread, on which I posted a lot! Distressing lack of memory! But I see that some basic ideas from even long before that still hold firm:

NIMBY-ism, density and transportation are tightly intertwined. But addressing NIMBY-ism vs. density certainly requires comprehensive planning too.

- The character and feel of desirable neighborhoods need to be preserved.

- To make them denser, that feel and character must not be threatened.

- You can have unobtrusive density if you do it without changing basic architectural appearance, while avoiding socioeconomic or cultural conflict or congestion. .

- Combining density with public transportation help to alleviate congestion.

- Partnering with employees to foster telecommuting can help ease congestion.

- Depending on geography and other factors, unobtrusive architectural density can be achieved by a) adding tiny structures behind existing, visible ones, b) raising existing structures uniformly and underlaying them with half-story basements, c) adding *setback* half story strictures on top--uniformity might be nice here too, but seems less of an issue), and d) a combination, or all, of the above,.

- Planning must be done to ensure maximum compatibility of newcomers with established residents.
