In a previous post we discussed why the arena will not be able to provide parking under Blocks 1119 and 1127. Security experts agree that parking areas should no longer be located below sports and entertainment facilities, and that buffer areas should be provided for pedestrian-only circulation at sport venues (See link). In fact, according to a recent Sports Illustrated article, the NFL and MLB prohibit parked vehicles within 100 feet of stadiums for security reasons.
On this site, since all of Block 1121 and most of Block 1120 will continue to house the LIRR train yard just below grade, the only available area of any consequence for underground venue parking is the Phase II Block 1129. This block, at below-grade levels, is also the only site available for Phase II residential/office parking. Is it possible to excavate deep enough to provide both residential/office and venue parking below Block 1129? Depending on the elevation of rock, this could easily add a hundred million dollars to the construction budget, a very conservative estimate. More likely: look for parking garages to spring up further east on Atlantic Avenue.
There really are only two options: either move the arena to a different site, or invest in rapid transit and don’t provide associated venue parking. If Madison Square Gardens is the model, no directly associated venue parking is required. If a MLB stadium, or Continental Airlines Arena at the Meadowlands is the model, build the arena someplace else, where people can drive to it.
