It has been rough sailing out at Coney Island of late, with —the real attraction is new amenities, such as green rooms, of which there are currently none, and a better sound and lighting system, not to mention the appeal of Coney Island itself and its proximity to the city.

And while amenities and location are nice, the real hallmark of Coney Center is its shimmering roof. Husser said the shape was chosen for a number of reasons, mainly the lightness of its structure. “It’s like a bicycle wheel with a massive steel rim and a ring at the middle for a hub,” he explained. “It’s a much lighter structure than one operated by trusses.” By bending the roof, it provides its own tension and thus requires less structure, which means less weight and less cost. The shape also helps minimize noise to adjacent housing and keep out the rain. The peaked end at the east side also achieves one of the project’s other main goals: to create a new gateway for Coney Island on perhaps its most common point of entry, Ocean Parkway. (Far more people drive to the area each year than ride the subway.)

At one point, the designers had considered a retractable roof, but a number of issues prevented its inclusion. First, the cost of construction and maintenance would have been considerable, especially given the corrosive seaside air. But more importantly, Coney Center is intended as a year-round facility: During the off-season, the 5,000 fixed seats beneath the canopy will be removed and replaced with an ice-skating rink.

Beyond the amphitheater, Grimshaw is also redesigning the playground that currently sits in the park, both to modernize it and because it is located on the footprint of the new and expanded back-of-the-house. Working with landscape architects Mathews Nielsen, the designers have created an elevated climbing structure that wends its way up, down, and around trees. The idea is to disrupt as few trees as possible while also creating a structure that recalls the nearby roller coaster. The team will also refurbish the popular handball courts across Surf Avenue.

Through a spokesperson, Markowitz praised the park as the latest step in the revitalization of Coney Island. “Replacing Asser Levy’s antiquated band shell with a state-of-the-art one will ensure that free community programming—it was used for 45 different community events last year—remains in Coney Island,” he said. “Moreover, it will be a key component of a revitalized Coney Island for the community and visitors in the days ahead.”

The project has come under some fire from locals who have complained about the possibility of increased noise and crowds, as well as the fact that some concerts will be paid, instead of free. But both the borough president and the designers counter that money generated from paid shows will go to putting on more free ones. “It’s win-win for the community and the city,” Husser said.

Construction is due to begin at the end of this summer’s concert searon, and the project is expected to be completed by the end of 2011.
