A flagpole lot, for those with inquiring minds, is a rear lot (the flag) that has a long, skinny driveway out to the road (the pole). The best example, or the most expensive one, is that $25 million dollar white elephant of a spec house on Round Hill Road, just before Baldwin Farms S. The builder had a big piece of land, even after selling off those two doomed parcels that used Baldwin Farms S. as access, but he wanted to retain the Round Hill address so he created a flag pole out to that road. Because zoning doesn’t credit the land in such an access way, he doesn’t have enough land to split it again (despite vague wording to the contrary), and he’s stuck with what he’s created. His real problem, of course, isn’t the flagpole – it’s the 25,000 sq. ft. he’s built hat few people want right now. It only takes one though, so perhaps that one will come along before the flag comes down.
