As the Lead Local Flood Authority (LLFA) we have a duty to investigate flood events that take place in the county.

Flood and water management projects and policies
We have developed a number of flood and water management projects and policies to address the risk of flooding in the county.
West Sussex County Council projects and policies
- West Sussex Lead Local Flood Authority (LLFA) Partnership Project: 'Over the wall' drainage project.
- Culvert policy (PDF, 808KB)
- Operation Watershed - An ongoing programme to invest in highway and environmental improvements.
- Flood Resilience Community Pathfinder Scheme
- Flood risk asset management - We maintain a register of structures and features which are likely to have a significant effect on flood risk.
- Shoreline Management Plans - These are plans to manage the threat from coastal change.
- Catchment Flood Management Plans - These consider future impacts from inland flooding.
- Preliminary Flood Risk Assessment (PDF, 10.4MB) - A high level, countywide analysis which considers past flooding and possible future flooding from local surface water runoff, ground waste, ordinary watercourses and flooding from canals and small impounded reservoirs.
- Surface Water Management Plans (SWMP) - These outline how surface water will be managed in a given area and will be implemented as part of Operation Watershed.
