England LPAs: Strategic Flood Risk Assessment Guidance Directs Flood Planning

• Local Planning Authorities in England must prepare Strategic Flood Risk Assessments (SFRAs) to inform planning decisions and manage flood risk.
• SFRAs assess flood hazards and vulnerabilities, identify risk areas, and guide appropriate development locations and mitigation measures.
• A wide array of stakeholders, including developers, emergency services, and other authorities, rely on SFRAs for various planning and operational purposes.
• SFRAs require continuous maintenance, regular review, and robust governance to remain up-to-date with changing policies and flood data.
• Collaboration among authorities and early, wide consultation are essential steps in the effective preparation and ongoing management of SFRAs.

The SFRA serves as a foundational document for LPAs, guiding decisions on appropriate development locations, suitable development types, necessary flood risk mitigation measures, and the implementation of sustainable drainage systems.

Local Planning Authorities (LPAs) across England are mandated to undertake a Strategic Flood Risk Assessment (SFRA) for their respective areas. This critical document, guided by official England strategic flood risk assessment guidance, serves as a cornerstone for integrating flood risk considerations into planning decisions, particularly concerning the design and placement of new development, infrastructure projects, regeneration schemes, and broader land use strategies.

The SFRA's comprehensive scope requires it to evaluate several key aspects of flood risk. This includes assessing the flood hazard itself, detailing its likelihood, potential depth, velocity, and duration. Furthermore, it must analyze the vulnerability of different land uses to flooding and determine the overall flood risk posed to people, property, essential infrastructure, and the natural environment.

Beyond assessment, the SFRA is tasked with identifying specific areas of flood risk, pinpointing opportunities to proactively reduce flood risk, outlining the requirements for more detailed site-specific flood risk assessments, and designating critical drainage areas. These findings are instrumental in enabling LPAs to make informed choices regarding appropriate development locations, suitable development types, necessary flood risk mitigation measures, and the implementation of sustainable drainage systems.

The SFRA is a foundational document for LPAs, directly influencing the preparation of local plans and spatial development strategies, the determination of planning applications, and the identification of essential infrastructure requirements. Its utility extends far beyond the immediate planning authority, serving a diverse array of stakeholders across various sectors.

The Environment Agency, for instance, relies on SFRAs to inform its advice regarding local plans and spatial development strategies. Developers and flood risk consultants utilize these assessments to gain a clear understanding of flood risk, inform their site-specific flood risk assessments, identify appropriate mitigation strategies, and support their planning applications. Emergency planners, emergency services, and local resilience forums depend on SFRAs for critical emergency planning, response, and recovery efforts. Risk management authorities incorporate SFRA data into their flood risk management plans and capital programmes.

Moreover, other council departments, such as those dealing with housing, transport, and open space, leverage SFRAs for their work. Coastal groups use them to inform the preparation and maintenance of shoreline management plans, while neighbourhood planning bodies consult SFRAs when considering the appropriateness of development. Other LPAs use them to inform their own SFRAs, especially concerning cross-border risks and opportunities. Minerals and waste planning authorities integrate SFRA data into their local plans, and combined authorities use them for spatial development strategies, potentially requiring additional flood risk information depending on their specific plans. This widespread reliance underscores the importance of robust Strategic Flood Risk Assessment requirements.

A crucial aspect of the England strategic flood risk assessment guidance is the imperative for continuous maintenance and review. An SFRA is not a static document; it must be regularly updated to reflect the latest information and ensure its ongoing relevance. An up-to-date SFRA is indispensable for making informed policies and decisions concerning the type and location of development, directly impacting development flood risk assessment England.

Ideally, the SFRA should be a web-based, 'living' document to facilitate quick and easy updates. This ensures it accurately reflects current flood risk, effectively supports planning decisions, informs site-specific flood risk assessments, identifies appropriate mitigation strategies, and aids emergency planning. Reviews or updates, which can range from minor addendums to full revisions, become necessary when national planning policy changes, new flood risk data or mapping becomes available, local circumstances shift (e.g., new flood defences or significant development), or following a significant flood event. This SFRA update review process is vital for maintaining accuracy.

Establishing appropriate governance arrangements from the outset is crucial for overseeing SFRA preparation, maintenance, review, and updates. These arrangements may mirror those for local plans or spatial development strategies. A single point of contact, possessing relevant skills and experience in flood risk management, should be assigned for SFRA preparation. Furthermore, a steering group comprising experts from various organizations and council departments is recommended to guide both the preparation and ongoing maintenance of the SFRA, ensuring compliance with Environment Agency SFRA advice.

Local Planning Authorities are encouraged to explore collaborative approaches, such as producing joint SFRAs with neighboring authorities. Such collaboration can lead to more effective strategies for addressing the causes and impacts of flooding, offering tangible benefits like cost savings, improved consistency across administrative boundaries, and accelerated decision-making. Joint SFRAs are particularly advantageous in situations where river catchments span multiple jurisdictions, regional flood risk management schemes are in place, cross-boundary development pressures exist, or resources are limited.

Crucially, the preparation of an SFRA necessitates early and wide consultation with relevant organizations. Opportunities for engagement should be maximized by integrating them with other planned consultation activities. A consultation specifically on the SFRA's scope must be conducted before any work is commissioned, ensuring all stakeholders have input into the foundational framework of the assessment.

Lawyers advising developers, planning authorities, or other stakeholders in England must understand this detailed Environment Agency guidance on preparing and maintaining Strategic Flood Risk Assessments (SFRAs). Compliance with these requirements is crucial for informing planning applications, mitigating flood risk liabilities, and ensuring robust development decisions.
