The Town website now hosts the 2003 Draft Comprehensive Plan. This is a fascinating document with lots of pieces, but I'll be a while digesting before I comment on it in depth.
The draft (without maps) is 2.4MB long, so it'll take a little while even if you have a high-speed connection. If you're on dial-up, you'll need to be very patient; set up the download and take a break.
Also, the maps tend to be large files (most are detailed and in color), and are linked separately from the main plan. Here's a list, with direct links.
