View SuDS Map layers
The 24 SuDS map layers are divided into four data categories (Infiltration constraints,
Drainage, Ground stability and Groundwater protection). Use the 'Data categories'
window on the top right of the map to select one of these catagories. Once a category
is selected the 'Component data layers' window will be populated with the summary
map for that data category along with the component layers that were used in the
derivation of the summary map. The component layers allow you to determine the basis
for the score in the summary layer.

name. If the button is disabled and the layer name is greyed out, you will need to
zoom in to be able to switch on the layer (all layers are visible at scales below

layers at that location. At the bottom of the 'All Layers' view are two buttons allowing
