The proposals were first revealed in April, for land on agricultural fields separating Pheasey and Streetly on Queslett Road and Aldridge Road.
No formal planning application has yet been made to the relevant planning authority which is Walsall Council.
However a petition was set-up to show how strongly people were opposed to the plans.
Now the petition has reached more than 3,500 signatures - gaining more than 2,000 signatures over two months.
And campaigners are still hoping to get more signatures in support.
Steve Lilly, the author of the petition, described these plans as putting "a massive slice of nature under threat" and cited how the area has rich bio-diversity that inhabit the hedgerows.
Pheasey Park Farm ward councillor Mike Bird said in April said the council will defend this site against any "unnecessary development".
The plan for this land is called Columba Park. It would cost £218.5 million to build over an eight-year period.
