In August 2007, a torrential rain storm knocked out nearly the entire New York subway system for hours. With the underground floods came a bunch of alarming developments. The MTA’s website couldn’t withstand the onslaught of visitors; their emergency alert system for service advisories was non-existent; and their anti-flood measures were ineffective at best and mostly useless. Over the last few years, the MTA has beefed up its website infrastructure and now provides near-real-time text alerts. The flood prevention was the last to come, but it’s finally in place and working.
According to Pete Donohue, the MTA completed a $31-million flood-prevention program. The highlight of this effort was a move to raise 1500 streetlevel grates a few inches off the ground. Instead of funneling rainwater underground and onto subway tracks and platforms, the waters are now siphoned to flood drains.
While New Yorkers saw the second-wettest June on record, weather-related subway delays are down significantly. For that, the agency deserves praise. Twenty-two months after a crippling storm, the system is ready for nature’s wrath.
New York City Transit is quite pleased with the performance of the grates. Paul Fleuranges sent me the above picture (which you can click to enlarge) and added a note about their use particularly on June 18 when the city received 1.84 inches of rain. “There’s no doubt given the amount of rain we’ve had this month, and the propensity of Hillside to flood out, we would have had serious problems if not for the grates,” he said.
