SuDS
A detailed analysis of surface water run-off and attenuation volume (to demonstrate how the proposed measures will aim to comply with Policy CE2 (g), which is to achieve a reduction of 50% of existing rates including climate change in the calculations and factoring in all flows into the sewer system including groundwater or other flows).
Information about the proposed SuDS types, their location, attenuation capacity, specification, structural integrity, construction, operation, access, and maintenance. (More sustainable green SuDS should be favoured over attenuation tanks).
Section/profile drawings of the SuDS if relevant (green roofs, blue roofs, sub-base attenuation, permeable paving, planters, species, etc.).
Drainage plans to show clearly how surface water run-off will be conveyed to the SuDS and any connections to the sewer system if necessary.
