Read more on Bruce Ratner's Atlantic Yards project Ratner’s Yards pretty dense By Ariella Cohen The Brooklyn Papers A new analysis by a noted Brooklyn architect indicates that the Atlantic Yards project is just as bulky as the state’s plans for Ground Zero. The architect, Johnathan Cohn, came up with the startling conclusion that the 17-acre residential and office village slated to surround Bruce Ratner’s proposed Nets arena would include as much built space, per acre, as the Ground Zero project, which will include more than 8 million square feet of office and commercial space plus the world’s tallest building, the Freedom Tower. Cohn used a standard city zoning measurement called the floor-to-area ratio, or FAR, to compare Ground Zero’s bulk with that of Ratner’s 9.1-million-square-foot residential and commercial development. To calculate a FAR, building area is divided by site acreage. Cohn said he relied solely on the developer’s own square-footage numbers, but subtracted the arena — as well as existing streets that will be demapped and incorporated into the project — so that his numbers would reflect the situation at the remaining 17 acres. As a result, he calculated that the residential and commercial component of the project has a FAR of 12 — just a miniscule .12 lower than the bulk of what is proposed for Ground Zero. “Whether it’s all in four towers or spread over 18, we are talking about the same ratio of building to area,†said the number-crunching architect, a blogger at Brooklynviews.com. Because it is a state project that doesn’t fall under city code, Atlantic Yards would exceed the maximum permissible FAR in Prospect Heights. If approved, it will be the largest development ever built in Brooklyn. Prospect Heights artist Jon Keegan’s visual simulation of the Atlantic Yards project seems to back up Cohn’s concern about the project’s bulk. Keegan created the simulation (see p
