East Side pols filed a zoning plan Thursday to block super-tall towers from rising in the neighborhood around Sutton Place. The application would cap buildings from 52nd St. to 59th St. east of First Ave. at no more than 260 feet. "We are drawing a line on the march of superscrapers at billionaire's row to protect our city's residential neighborhoods," said Councilman Ben Kallos (D-Manhattan), who submitted the plan along with Councilman Dan Garodnick (D-Manhattan), Manhattan Borough President Gale Brewer, and Sen. Liz Krueger (D-Manhattan).
