Deputy Mayor Jenny Duncan said the reserve's future was as important for all of Whanganui community, not just Castlecliff.
"It's everyone's beach, playground, where we walk our dogs, picnic, fish and swim," she said.
"Generations of families have grown up with the beach and reserve in their back yard. It also has cultural and spiritual significance for local hapū and iwi as a place for gathering food and materials."
Duncan said public submissions provided an opportunity for everyone in the Whanganui district to have their say.
"Managing the reserve in partnership with the community creates a sense of ownership and pride that has flow on effects throughout the wider Castlecliff and Whanganui communities," Duncan said.
Edmonds said the plan had a number of key objectives.
"It also includes an action plan, from reserve use through to pedestrian and vehicle access, parking, dune stability and dealing with plant and animal pests."
The draft plan and submission forms are available online at www.whanganui.govt.nz/castlecliff-coastal-reserve.
Copies of the plan and submission forms are also available from the council office at 101 Guyton St and copies can be viewed at Whanganui libraries.
Submissions close at 5pm on August 17.
