The allotments would replace a site sold for development
New allotments are to be developed near a nature reserve at Rhos on Sea in Conwy.
The original plan was to develop a site found by the council but voluntary group Bryn Euryn Users Assocation offered to donate land at Pabo Lane.
The group said the move could safeguard the council's choice of location as an open space "in perpetuity".
Conwy Council board members backed the proposal for 77 allotments, including 12 disabled-friendly plots, on Tuesday.
The former allotment site was sold for development in 2007.
As part of the conditions of the sale the assembly government stipulated that an alternative allotment site should be found in the Rhos on Sea area.
The site chosen by the council was at Tan y Bryn Road, but following consultation objections were received about the loss of open space to the community.
Since then the Bryn Euryn Users Association has approached the council with an offer to buy alternative land, and donate it to the council.
It is recommended that councillors accept the offer, but if it does not work out, then the Tan y Bryn site will be used instead.
Mr Lyn Davies, street scene manager with Conwy Council added: "The plans for the new allotments at Rhos on Sea include 65 regular allotments and 12 raised bed allotments - designed to be wheelchair accessible."
Conwy Council Board meets at 1400 GMT on Tuesday the council offices, Conwy.
