What are these Enhance/Warning Zones on Cape Cod in the Hyannis and Barnstable areas?

Two of the EWZ are near the approach/departing areas of Otis Air NGB, but other runways do not have these. I also thought they might be for sea-planes, but the areas are not centered on water and more over neighborhoods. Then I thought, maybe these rich folks requested and received the most they could from the FAA, which was not a restricted zone, but just warning zones for us nefarious pilots. I see these a lot, but most are Warning and not Enhanced like a two of these.
