Re: Trees, development & contaminated land

Former railway sidings with conditioned approval to develop to
residential;
Various trees to be retained.
Site found to have unacceptably high levels of heavy metal contamination.
Proposed to contain the contaminants by capping the site to a depth of
600mm.
What to do around the trees?
Any useful suggestions?

Hi Jerry,

I'm not sure the following would be suitable in your case, but I've
recently had experience of this. When I pressed the soil testing company as
to where exactly the contamination was they agreed to take more samples
which showed the major contamination to be isolated to a 2m x 2m patch
under one of two TPO'd trees. I have agreed with the developer and
Contaminated Land officer that the offending top 300mm of this area could
be removed using an air spade (air pick) and clean topsoil backfilled.

Hope this helps!
