Supplementary Planning Document
A Supplementary Planning Document (SPD) provides detailed guidance to support policies in a Local Plan, helping applicants understand how those policies should be applied when preparing planning applications. Speak with a consultant to understand which SPD drainage and flood risk requirements apply to your site. SPDs are explained within the GOV.UK national planning policy framework.

Case Example
A council publishes an SPD on sustainable drainage, setting out specific SuDS requirements and design standards that developers must follow when submitting planning applications.
Follow local policy. Rida Reports aligns your FRA with SPD guidance.
