Flood Risk & Drainage Chapters for Environmental Statements (ES / EIS)
Standalone flood risk and water environment chapters for Environmental Statements, prepared to EIA Regulations 2017 standards and ready to drop into your co-ordinated ES.
ES / EIS Flood Risk & Water Environment Chapters
Where a development is EIA development, the Environmental Statement must assess likely significant effects on the water environment — including flood risk, surface and foul drainage, water quality and hydrology. We prepare the flood risk and drainage chapter as a self-contained, referenced ES chapter that slots straight into your co-ordinated Environmental Statement.
Our chapters follow the standard EIA structure — policy and legislative context, methodology and significance criteria, baseline conditions, assessment of effects, mitigation and residual effects — and are cross-referenced to the site-wide FRA, drainage strategy and any hydraulic modelling. We work alongside your lead EIA co-ordinator, architects and other chapter authors to keep terminology, receptors and significance criteria consistent across the ES.
What the chapter covers
- Legislation & policy context (NPPF, PPG, WFD)
- Assessment methodology & significance criteria
- Baseline water environment & flood risk
- Construction & operational effects
- Surface water & foul drainage strategy
- Mitigation & residual effects
- Cumulative effects assessment
- Cross-referenced technical appendices (FRA, drainage)
When you need an ES flood risk chapter
EIA development, screening/scoping outcomes and major schemes typically trigger a dedicated chapter.
EIA development
Schedule 1 and Schedule 2 development that is screened as EIA development requires an Environmental Statement, with the water environment and flood risk assessed as a chapter.
Scoping opinion requires it
Where the LPA's scoping opinion identifies flood risk, drainage or the water environment as a matter to be assessed, a dedicated ES chapter is expected.
Major & sensitive sites
Large residential, commercial, energy or infrastructure schemes — particularly those near watercourses, in Flood Zone 2/3, or affecting protected water bodies.
Co-ordinated ES
When you already have an ES team and simply need the flood risk and drainage chapter authored to match the rest of the Environmental Statement.
