A state senator and some Queens residents are asking questions about a waterfront development that's seen some changes recently.

State Senator Tony Avella joined residents in Whitestone on Monday to call on the state's Department of Environmental Conservation to be more transparent.

They want to know why the DEC allowed developers of the Whitestone Waterpointe site to use a different soil on the property than originally agreed to. 

DEC officials have said that despite the changes that all the rules are still being followed.

Still, those against those changes argue that any modifications to what was originally agreed upon were approved without their notification. 

"[They] Should have reached out to me, other elected officials, the community board and the community to say by the way, the developer wants to change the protocol that was agreed upon, because we would have said no," said Avella.

According to the DEC, they did distribute a fact sheet about the change back in September.
