Hi Adam and welcome to the forum.
I was under the impression that the land is being prepared for the Aldi.
The development site is quiote a large one from what I have heard and is to stretch right down to the old Clay Cross works.
I 'believe' it is to be used for businesses and houses.
It's been said that before the work lower down can begin there needs to be a 'land clean up' but I'm not sure what this entails.
I can find very little on the internet about this development and the latest updates have said something like 'not yet available for public viewing' regarding plans for it.
If I hear anything more though I will post - having said this there may well be another member who comes along and can tell us more.
