Parents are opposing plans to erect a new school building to cater for extra children.
Lancashire County Council wants to increase the intake from 60 to 90 pupils at Trinity CE/Methodist Primary School, in Buckshaw Village.
“I find the idea ridiculous to split children over two sites at least a 10-minute walk there then back again, over a busy road. I am a non-driver.”Jayne MacDonald
As part of the plans, a new building could be constructed nearby to expand the school and create room for the increased number of pupils.
But parents oppose the plans and have launched a website www.buckshawschoolsplit.co.uk.
They are upset that siblings would be in different school buildings and there would be a 10 to 15-minute walk between the sites.
Among their other concerns are the logistics of the school run, disruption to children and the impact of Trinity becoming a larger school with more pupils.
More than 110 people have already signed a petition calling for a new school to be put on the site, rather than a second building for the existing school.
Mum Jayne MacDonald has four children, three of which currently attend Trinity.
She opposes the new building for several reasons, including the effect on the school run.
She said: “I find the idea ridiculous to split children over two sites at least a 10-minute walk there, then back again, over a busy road. I am a non-driver.”
Matthew Tidmarsh, the county council’s head of asset management, said: “We need to increase the size of this popular school to meet the expected additional demand for places now and in the future.
“We are constantly reviewing changing demographic factors to make sure the number and location of the school places we provide are adequate throughout Lancashire.
“We are currently consulting on this expansion and views will be considered as part of the decision-making process.”
