The Office of Public Works (OPW) is looking for your say on the future of parking at the Phoenix Park.
This also includes the potential introduction of parking fees.
The online survey is taking submissions until 22nd May.
One government Senator has called on the OPW to improve the park's transport links, before introducing charges.
Fine Gael's Emer Currie says the government is prioritising fees over public transport.
Senator Currie has also called for improved parking access for the disabled and elderly at the park.
She says currently, there are less than 1% of the 2,200 spaces, available for accessible parking.
