A formal comment to the planning authority counts for more than a petition. Say in your own words how this would affect you, and stick to planning grounds.

- Good planning grounds include: impact on the Green Belt or countryside, energy use and carbon, water supply, noise, traffic, wildlife and heritage. Developers' promises are not guarantees: ask for them to be made binding.
