Why the sharp spike from 2009 to 2010? That’s drilling down for another post, another day. For those who prefer tables of raw numbers:
The other agencies involved are in the table below. DPR is Parks and Recreation, the department, not the TV show; the complaint was about “Loud Talking – Street/Sidewalk” and seems to have been mis-categorized. The other two abbreviations are Dept. of Sanitation (all those garbage trucks clanking about at 3am) and the Economic Development Corporation. The first few for the EDC that I scanned were about helicopters hovering, flying above, or flying too low and making a racket. I know engine noise from ferries goes to the DEP (I filed a few of them). Are there inspectors at the EDC hired for the sole purpose of monitoring chopper noise. What do they do on an average day and how do they do it? If you’re not NORAD or NYPD or some such, you’re unlikely to have choppers of your own to chase after the noisy… but I digress. I wonder why the city doesn’t fold chopper noise oversight into the Dept. of Environmental Protection’s purview. Makes more sense.
