Historic District on the Move?

Plans to possibly extend the Capitol Hill historic district northward have made the news again. This time Roll Call (subscription required) is on the beat. The article contains a little discussion of how a historic district might protect H Street from certain types of incongruous development. Various people have advocated extend the historic district to different points (it currently ends at F Street). Right now there is certainly some buzz about pushing its northern boundary to include H Street. Others want to push a block or two further, and Richard Layman has suggested extending it to Florida Avenue.
