While i was at Blogfest, the Park Slope Civic Council announced that they want to triple the size of Park Slope's historic district. The Brooklyn Paper has the story. Here's an excerpt:

Brooklyn’s largest historic district would triple in size under a proposal unveiled on Thursday by a Park Slope community group.

The Park Slope Civic Council is aiming to expand the neighborhood’s
1,975-building historic district to include more than 5,000 structures
that constitute nearly the entire neighborhood bounded by Prospect Park
West, Flatbush Avenue, Fifth Avenue and 15th Street.

“The Civic Council recognizes the historical and architectural
significance of the entire Park Slope neighborhood and seeks to forever
preserve its unique character and sense of place,” said the group’s
resolution, which was approved unanimously on Thursday night.

The plan, a decade in the making, calls upon the city’s Landmarks
Preservation Commission to expand the existing historic district —
which includes the eastern part of the neighborhood between Park Place
and 14th Street — in three phases, first with a swath of 1,350
buildings bound by Flatbush Avenue, Prospect Park West, 15th Street,
Seventh Avenue, and sections of Union Street and Fifth Avenue.
