Preliminary Flood Consequence Assessment, Caerwys
09-01-2008
Proposed residential development on former commercial land. Land shown to be zone C1 and protected by existing defences.

Question is whether the land constitute loss of flood plain if it is supposed to be protected.
Preliminary Flood Consequence Assessment, Llangammarch
04-01-2008
Proposed residential development in zone C2 undefended. Formerly a building on the site and no history of flooding, but current EA flood map predictions suggest otherwise and planning permission is therefore likely to be refused. However mapping could be wrong as topo levels indicate the site is above the EA predicted flood levels.
