Local Authorities across the UK face growing challenges in managing environmental responsibilities while balancing the demands of urban development and sustainability.
As a leading provider of flood risk intelligence, we are dedicated to supporting Local Flood Authorities in managing and mitigating flood risk effectively. Our expertise in groundwater flood risk modelling and climate change impact analysis enables us to provide robust, data-driven solutions tailored to your needs.
GeoSmart has over a decade’s experience providing support services for Local Authorities, County Councils, and Lead Local Flood Authorities in England and Wales.
Our Key Services for Local Flood Authorities:
- Groundwater Flood Risk Modelling – High-resolution floodmaps identify areas at risk of groundwater flooding, informing local flood risk management strategies and planning policies on this often overlooked aspect of flood risk. Our rigorous modelling approach provides the best quantification of this risk available in the market.
- Climate Change Impact Analysis – Projections of future flood risk scenarios, helping authorities plan long-term resilience strategies in line with regulatory requirements. Through our FloodSmart Analytics tools we quantity risk to every property and land title in Great Britain to understand total flood risk nationally.
- Flood Risk Mapping & Reporting – Customised flood hazard data and reports to support policy development and emergency planning. We have assisted local governments with data and services to cover a range of needs ranging from disaster prevention planning through to post flooding S19 assessments.
- SuDS & Drainage Assessments– Evaluation of sustainable drainage options to reduce flood risk and enhance water management.
- Consultation & Expert Support – Technical guidance on flood risk policy, planning applications, and strategic flood risk assessments. We also offer software technology which integrates online mapping and portfolio analysis tools to help analyse, visualise and communicate risks.

Our solutions are designed to help Local Flood Authorities meet their responsibilities under the Flood and Water Management Act, ensuring informed decision-making based on the latest scientific insights.

Frequently Asked Questions
We can provide comprehensive flood risk assessments, flood mapping, S19 investigations, flood resilience surveys and Sustainable Drainage Systems (SuDS) reports to help local authorities make informed decisions and manage flood risks in their communities.
A Section 19 Flood Investigation is a critical process carried out by Lead Local Flood Authorities (LLFAs) under the Flood and Water Management Act 2010. When a significant flood event occurs, this investigation ensures that the causes and impacts are thoroughly examined, and appropriate measures are identified to mitigate future risks.
Yes, we assist Local Authorities in ensuring that developments meet the requirements of the National Planning Policy Framework (NPPF), including guidance on sustainable drainage, flood risk management, and risk of contaminated land.
