Section 19 / Flood Investigation Support
Get in touchThe Flood Protection Associates provides Section 19 / Flood Investigation Support for local authorities, developers and infrastructure projects. The service delivers technical flood assessments, hydraulic analysis and evidence-based reporting to help investigate flooding incidents and support informed decision-making.
What Is Section 19 / Flood Investigation Support?
Section 19 / Flood Investigation Support is the technical assessment of flooding events to identify causes, contributing factors and potential mitigation measures. The Flood Protection Associates prepares detailed investigations using flood data, site inspections and engineering assessments to support statutory flood investigations.
Support may include hydrological analysis, hydraulic modelling, drainage assessments and technical reporting following significant flood events.
What Types of Section 19 / Flood Investigation Support Are Available?
The Flood Protection Associates provides Section 19 / Flood Investigation Support for a variety of flooding scenarios and infrastructure projects. Services are tailored to the scale and complexity of each investigation.
Flood event investigations – Technical assessments of the causes and impacts of flooding.
Hydrological assessments – Analysis of rainfall, catchments and runoff behaviour.
Hydraulic modelling support – Simulation of flood flows and drainage performance.
Drainage network reviews – Assessment of surface water and drainage infrastructure.
Technical reporting – Preparation of evidence-based reports to support decision-making.
Each investigation is developed using recognised engineering methods and available site information.
When Is Section 19 / Flood Investigation Support Needed?
Section 19 / Flood Investigation Support is commonly required after significant flooding events or where detailed technical evidence is needed. The Flood Protection Associates provides investigations that help organisations understand flood mechanisms and identify appropriate mitigation measures.
Typical situations include:
Significant surface water flooding
River flooding incidents
Highway flooding
Drainage network failures
Development-related flooding concerns
Infrastructure flood events
Planning and post-event reviews
Early investigation helps identify risks and inform future flood resilience measures.
How Does Section 19 / Flood Investigation Support Work?
Section 19 / Flood Investigation Support follows a structured engineering process. The Flood Protection Associates gathers evidence and prepares technical assessments to support flood investigations.
Data collection – Rainfall, flood records and drainage information are reviewed.
Site inspection – Existing flood pathways and drainage features are assessed.
Technical analysis – Hydrological and hydraulic assessments are completed.
Reporting – Findings, conclusions and recommendations are documented.
Project support – Technical information is provided for stakeholders where required.
Most investigations are completed within approximately 2 to 6 weeks depending on the complexity of the flooding event and available information.
Who Needs Section 19 / Flood Investigation Support?
Section 19 / Flood Investigation Support assists organisations responsible for understanding and managing flood risk. The Flood Protection Associates supports clients across both public and private sectors.
Typical clients include:
Local authorities
Highway authorities
Developers
Civil engineers
Planning consultants
Infrastructure owners
Commercial property owners
Each investigation is tailored to the objectives and technical requirements of the project.
How Much Does Section 19 / Flood Investigation Support Cost?
Section 19 / Flood Investigation Support typically costs from around £1,500 to £10,000 depending on the scope of investigation, modelling requirements and reporting complexity. The Flood Protection Associates provides project-specific quotations.
Typical cost ranges include:
Basic technical assessments – approximately £1,500 to £3,000.
Medium-scale investigations – around £3,000 to £6,000.
Complex investigations with modelling – from approximately £6,000 to £10,000+.
Final costs depend on site size, available information, survey requirements and technical analysis.
What Are the Benefits of Section 19 / Flood Investigation Support?
Section 19 / Flood Investigation Support provides reliable technical evidence to help understand flood events and identify practical solutions. The Flood Protection Associates delivers clear engineering assessments that support future flood risk management.
Benefits include:
Improved understanding of flood causes
Evidence-based technical reporting
Support for future flood mitigation
Better planning and infrastructure decisions
Identification of drainage issues
Assistance with long-term flood resilience
Comprehensive investigations support informed decisions following significant flooding incidents.
What Regulations Apply to Section 19 / Flood Investigation Support?
Section 19 / Flood Investigation Support is prepared with reference to relevant UK flood risk legislation and guidance. The Flood Protection Associates produces technical assessments that support statutory flood investigations where applicable.
Relevant legislation and guidance may include:
Flood and Water Management Act 2010
Section 19 of the Flood and Water Management Act
National Planning Policy Framework flood risk guidance
Environment Agency flood risk guidance
Lead Local Flood Authority procedures
Specific requirements depend on the authority responsible for the investigation and the nature of the flood event.
