We saw the sign up yesterday and thought to inquire. Here is the email response we received:

Ms. Furnari:

The County Executive forwarded your e-mail and asked me to respond.

On Thursday, August 23rd, the Brookdale Dog Park will be closed for maintenance, so we can pull weeds, cut grass, etc. We apologize for the inconvenience.

Anthony Puglisi
Public Information Director

No word on how many hours this will take, but forewarned is forearmed.
