The future of the Castlecliff Coastal Reserve is open for public input.
Whanganui District Council's draft management plan for the reserve outlines the use, development, maintenance, protection and preservation for the reserve over the next decade.
The new plan will include the north mole alongside the reserve and land seaward up to the mean high water tide mark.
"It's including the mole because its such a significant feature... but it's not going to affect the upgrading of it," council policy planner Victoria Edmonds said.
It will take in an area 3.1km north from the Whanganui River mouth and covers about 38ha, mostly in dunes and the Karaka Wetland.
