Many of you will recall that following the flood event, Tattenhall Wildlife Group (TWiG) immediately contacted Bolesworth Estate, to determine whether the next Phase of flood management on the Mill Brook might be undertaken and so reduce future flood risk.
The key objective is to hold back flood water at times of peak flow overspill from the Mill Brook further upstream at China Meadow.
The good news is that work is to commence on Phase 2a on Monday, 10 May.
In short, a temporary flood water storage installation with seepage barriers will be constructed. Earthwork bunds will be created above ground level and graded so as to blend into the terrain. Other design features will be installed to facilitate the project and also allow for uninterrupted water flows at normal times.
For information, there might be some temporary sedimentation caused during the works. The landowner at Tattenhall Hall has been advised of this and in relation to the Mill Pond.
If sedimentation is higher than expected, then the contingency plan is that a temporary flow diversion be established through the wildlife area (created during Phase 1) which will, in effect, filter out any sediment.
Phase 2a represents collaborative working at its very best and consolidates the work of Phase 1.

We will keep you updated as work progresses.
