Campaigners are set to protest this week over plans for a play area next to a railway line which are included in proposals for a new housing development.
Social housing company Cartrefi Cymunedol Gwynedd (CCG) want to build 24 houses on land at the rear of Tan y Celyn, Sŵn y Môr and Talardd in Llanwnda.
Critics fear a proposed play area next to a railway line and gas sub station could put children's lives at risk, although an anti-climb fence more than two metres high is planned along with other fencing. They are planning to protest against the plans on the morning of Wednesday, February 6.
Gwynedd council planning chiefs are satisfied with the proposals and have recommended them for approval, while CCG bosses insist there are measures to ensure youngsters' safety.
The proposals were deferred by Gwynedd councillors at a planning meeting in January last year to discuss concerns with the applicant and relocating the play area.
But the plans will come before the committee again on Monday with the recreational space still in the same area.

Cathryn Mackay, a mum of two, said: "I have young children and I would not be happy to let them go down to the proposed playing field unattended.
"The potential danger of children going over the fence or going around it and going on a railway track, which has a blind corner at the very spot that they intend to place this playing field, is shocking.
"No one has consulted with us, and all we ask is that they relocate this playing field away from the tracks so it is not deemed to be an attraction for children to go there."
Aeron Jones, county councillor for Llanwnda, said: "The arrogance of the consultants and the applicant is beyond belief."They were to look at relocating the playing field away from the railway tracks. However, they have re-submitted the same plans in again to be discussed.
"They lost at the previous meeting and I hope that the elected members who sit on the planning committee will again support the residents and myself in refusing this application on the grounds that children’s safety is more important than houses."

Ffrancon Williams, chief executive of CCG, said: "This is a fantastic opportunity for us to develop affordable housing in an area where demand is high.
“With nearly 200 applicants on the waiting list for affordable housing in Bontnewydd, Llandwrog and Rhosgadfan alone, this scheme will make available suitable housing to local people.
"It goes a long way towards providing people with efficient, modern and comfortable homes in the communities they want to live.
"We've drawn up plans to take into consideration all measures to ensure the safety of any youngsters using the open space within this scheme.
“It’s a mixed tenure development, providing affordable housing to rent and to buy, giving residents a range of housing opportunities in line with Gwynedd Council’s housing strategy, our own development strategy and the Welsh Government’s aim to build 20,000 new homes in Wales by 2021."
