Advice on flood risk management for developers
Identifying risk of flooding for new development
To assess if a location has a possibility of flooding, there are a range of possible information sources in the planning process.
- Strategic Flood Risk Assessment
- Metrogreen - Flood Risk and Water Management
- Gateshead Council Lead Local Flood Authority: historic flooding records, flood risk management assets, local flood risk management strategy and local flood schemes.
National and local planning policies, guidance, and standards
To manage the flood risk of new development, it is important to refer to relevant national and local planning policies, guidance, and standards:
- National Planning Policy Framework (Chapter 14 - para.159-169)
- National Planning Practice Guidance - Flood Risk and Coastal Change
- - CS17 and site specific policies; - MSGP 29, 30, 31
- Non Statutory SuDS Technical Standards (DEFRA March 2015)
- Non Statutory SuDS Technical Standards Practice Guidance (LASOO)
- Association of SuDs Authorities: Knowledge and Resources
- Flood risk assessments: climate change allowances
Environment Agency's guidance and standing advice
The Environment Agency is a statutory consultee on flood risk for some planning applications (within 20m of main river, critical drainage problem areas and certain categories of development in flood zone 2 and 3, subject to the flood risk vulnerability classification).
- Standing advice for local authorities
- Guidance on Sequential Tests
- Preparing a flood risk assessment standing advice
- Environment Agency organisation
Gateshead Lead Local Flood Authority's guidance and standards
The Lead Local Flood Authority (LLFA) undertakes a statutory consultee role providing technical advice on surface water drainage (including Sustainable Drainage Systems [SuDS]) to the Local Planning Authority (LPA) for major developments (10 dwellings or more). The LLFA also provides technical advice to the LPA on a range of other local flooding issues.
