The response from DDC is the comment in italics below. If you get a "24-hour notice" and don't see "No Parking" signs, or have any questions, call the community liaison (CCL) to confirm.
The notice that Iva, the CCL, distributed, indicates a variety of locations that may be impacted – if that block will be impacted, Iva will provide a 24 hour confirmation notice. You can also refer people to call her directly – 516-714-6431. She has the latest information.
