Drainage and flood issues are much easier to manage when they are addressed early. This planning help resource is aimed at project teams who need to understand what to ask before a scheme progresses too far.
Use this guidance to check what may be needed before you submit information.
If the wording on your planning condition, tender request or site constraint is unclear, send it to EnviroSolution and we can advise which report, survey or assessment is likely to be relevant.
What should be reviewed early?
Flood constraints, site levels, discharge options, infiltration potential, local policy expectations and likely SuDS opportunities should all be reviewed at the appraisal stage where possible.
Why it matters commercially
Late drainage changes can affect layouts, hardstanding, levels, build costs and planning timescales. Early clarity gives the design team more room to respond sensibly.
How to use this resource
Use it as a front-end prompt to shape the right surveys, the right drainage conversations and a more realistic view of site constraints.
