Update: According to Newsday the Public Hearing will be at the Legislature's offices next Monday, time TBA.
The Nassau Legislature Office is located at 1550 Franklin Avenue in Mineola. Thank you @Janefisher13 for sending me the address on twitter.
Today the Nassau County Legislative Rules Committee voted on and passed the Referendum. This was the first step in order to get it on the ballot for August 1st. The four republicans on the board voted yes for it while the 3 democrats abstained from voting.
From what I read there will now be a public hearing at a location TBA next Monday May 23rd. This is a good opportunity for supporters to show solid numbers and let their voice be heard, I intend on attending and will post the location once it is released.
