The petition to transfer Riverside Park and Lewes Road Recreation Ground to Newhaven Town Council will close on Saturday October 12.
Organisers Riverside Park Community Voice plan to present the petition to Lewes District Council on Wednesday October 16 and East Sussex County Council on October 22.
There are currently more than 600 signatures on the paper and online petition.
But organisers are aiming for 750 signatures and need your help to achieve this.
Jo Pettitt from Riverside Park Community Voice, the pressure group which has orchestrated the petition said: “Thanks to those who’ve signed already!
“Please sign if you haven’t and share with your friends.”
The petition calls upon Lewes District Council and East Sussex County Council to transfer the areas known as Riverside Park and Lewes Road Recreation Ground in Newhaven to Newhaven Town Council.

The move to protect the area was made after Lewes District Council sold the land to the Kuwaiti company KEH Developments, which wanted to build the world’s largest indoor water park in Newhaven.
But the controversial plans fell through after it was discovered it would be too expensive to build on the land as some of it was contaminated.
Riverside Park Community Voice has been asking residents what they would like to see done at the Newhaven park, just off Lewes Road, including the high ground, wetland and path to Piddinghoe.
