Introduction 1.2 It is best practice for the Main Issues Report (MIR) and the preparation of the Local Development Plan (LDP) to be informed, and supported, by a strategic overview of flood risk management issues, in the form of a Strategic Flood Risk Assessment (SFRA). 1.3 The SFRA allows local authorities to consider flood risk early on in the development plan process. It should also provide a strategic overview of flood risk in the LDP area, and support officers in the identification of the areas most suitable for development. It can also be used to identify sites that should not be used for development but are more suited to sustainable flood management. 1.4 The assessment of land for flood risk that we have undertaken has been considered at both the strategic level as well as the local level. The SFRA includes information gained from SEPA as well as Aberdeenshire Councils Flood and Coast Protection Team at the time of the preparation of the assessment. Also included in the SFRA is an analysis of planning policies from national, strategic and local policies and how the council complies with these policies. 2. Aims and Objectives 2.1 The main aim of the assessment is to provide information so as to avoid increasing overall flood risk by avoiding locating development in areas which are at risk of flooding through careful consideration of all types of flooding, including costal/tidal, pluvial and river based. 2.2 The main objectives of the SFRA are to: • Ensure development does not take place in areas of flood risk or contribute to flooding elsewhere; • Provide the baseline on flooding issues for the Environmental Report; • Identify the flood risk areas based on the risk framework presented in the Scottish Planning Policy (SPP); and • Provide an evidence-based report to inform the LDP. • Develop policies for flood risk management. 2.3 The key role of the SFRA is to identify if the potential development sites within the MIR are suitable for allocation as part of the subsequent plan making process. It should also mean that significant flood risk mitigation measures should not be necessary to overcome flood risk as the sites that would require this should be screened out through the allocation of sites, or risks managed through, for example, the location of open space. 3. Background 3.1 The Flood Risk Management (Scotland) Act 2009 sets out a statutory framework for delivering a sustainable and risk-based approach to managing flooding. The Act also sets duty on SEPA and local authorities to exercise flood related functions to reduce the overall risk of flooding and also to promote sustainable flood risk management. There are also two other main tasks which are set out in the act which are the preparation of assessments of the likelihood and impacts of flooding, and catchment focused plans to address these impacts. 3.2 Flood risk management plans are now in place across Scotland which require to be taken into account when development plans are being 1 prepared. To provide a baseline to inform the LDP SEPA advise that it is helpful to prepare a Strategic Flood Risk Assessment. This is to ensure that new development would be free from significant flood risk and new development would not increase flooding elsewhere. 4. Planning Policy 4.1 The Scottish Planning Policy suggests that the land allocated for development should be located in areas with the lowest risk to flooding first with the highest risk areas generally not suitable for most forms of development. The SPP also contains a risk framework which shows the return period and probability associated with river and coastal flooding as shown in Table 1. Table 1: Risk Framework RISK FRAMEWORK Category
