An OTBKB reader just sent this in:

Good morning.   I couldn’t find anything on your blog and am wondering
if others know that they are installing parking meters on 7th Ave
between 10 and 12 sts.  There is already no parking in the nabe, and I
didn’t see any signs from the community board or the DOT for review.
Any info?  Thanks

I did read on Gowanus Lounge that new parking meters are being installed from 11th to 15th Streets on Seventh Avenue. Here’s a snippet from GL:

The Department of Transportation is adding parking meters on Seventh Avenue from 11th Street through 15th Streets. A poster on Brooklynian quotes some information about it from Community Board Six:

The
Department of Transportation is under no legal obligation to notify
affected property owners, residents, etc. of the installation of
parking meters. We did receive a notice from them, which was announced
at our last Transportation Committee meeting and last general meeting,
but did not seem to get picked up by any local papers for broader
attention.
