#SuDS in InfoWorks ICM
In InfoWorks ICM 6.5 and later the SWMM 5 LID Controls were added to the Subcatchment Grid of ICM. Here is a copy of the ICM Help File. The LID Controls are entered in the Subcatchment Grid (1), in the SuDS or LID Tab (2), it uses SWMM 5 LID Control Types (3) and has a grid of all of the LID or SuDS data. More here on our Innovyze Blog.
