At work (local authority) I have a flood zone that was created ArcGIS software from Elevation Model (1 meter accuracy). The zone covers an urban area. I cannot get to the resolution of which building is more effected by flood and which isn't but I do have a layer of all buildings. Question is whether I should cut the buildings out of the flood zone, and why?

At work (at a local authority), I have a flood zone plan/layer that was created using ArcGIS software from an Elevation Model which has an accuracy of 1 metre. The zone covers an urban area. I cannot get to the resolution of which buildings will be more effected by flood and which won't, but I do have a layer of all buildings.

The question is, whether I should cut the buildings out of the flood zone, and why?

I'm new to this forum (and water engineering in general) and hope this question is good as I could find no answer in the forum.

Thanks you whoever can answer or give some instructions.
