Background information on the LFRMS is provided in section 3 of this report. HCC commissioned Halcrow to undertake a Strategic Environmental Assessment (SEA) of the LFRMS in April 2012. The SEA considers the potential impact of the strategy on various environmental receptors. This report represents the scoping stage, which summarises the environmental baseline for the County and proposes draft SEA ‘objectives’ which will be used to assess the environmental performance of the LFRMS. Further description of the SEA process is provided in section 1.3. The SEA should be read in parallel with the main LFRMS report, i.e. the Hampshire Local Flood Risk Management Strategy. 1.2 Study Area The study area for this LFRMS is the area within the administrative boundary of Hampshire County Council. Hampshire is made up of 11 District and Borough authorities; Basingstoke, East Hampshire, Eastleigh, Fareham , Gosport, Hart, and Deane, Havant, New Forest, Rushmoor, Test Valley, and Winchester City. 1.3 Strategic Environmental Assessment SEA is the systematic appraisal of the potential environmental impacts of policies, plans, strategies and programmes, before they are approved. It ensures that any implications for the environment are fully and transparently considered before final decisions are taken and is required by an EC Directive (2001/42/EC) ‘on the assessment of the effects of certain plans and programmes on the environment’, known as the ‘SEA Directive’, which came into force in 2004. The Directive is implemented in England through the Environmental Assessment of Plans and Programmes Regulations (SI 1633 2004). This legislation makes SEA a legal requirement for certain plans and programmes which are likely to have significant effects on the environment. Local flood risk management strategies are statutory plans and are subject to the requirements of SEA. LLFAs need to take a proportionate approach to applying SEA to local flood risk management strategies, particularly when environmental effects are not evident in the early stages of plan development. As the strategy develops more detail, the scope of the SEA should be reviewed. i Consultation with the statutory consultees for SEA (see section 2) should assist with the methodology and scope of the SEA. The environmental effects of alternative flood risk management approaches and mitigation measures (including potential policies and objectives) will be assessed and the results used to help select a preferred strategy option or LFRMS measure which is economically viable, meets environmental objectives and complies with legal requirements to protect designated sites of nature conservation, cultural heritage, Doc no: 0 Version: 1 Date: 17 Sept 2012 Filename: LFRMS SEA 2nd draft Scoping Report 25,9,2012 1 Hampshire LFRMS SEA: Scoping Report water bodies or landscape interest. The approach used is based on our knowledge of the area, professional judgement and supported by published literature. This Scoping Report summarises the environmental baseline for the County, focusing on issues that are specifically relevant to flood risk associated with ordinary water courses and surface and ground water. However, the second principal output of the SEA, the Environmental Report, will also include consideration of the cumulative environmental effects of flood risk from the LFRMS in addition to flood risk from main rivers, the sea and the sewerage network, where these sources are relevant. The statutory consultees for SEA (English Heritage, the Environment Agency and Natural England) and key stakeholders will have opportunity to comment on the SEA findings. Further detail on the consultation process is provided in section 1.7. 1.4 Habitats Regulations Assessment Due to the potential for the LFRMS to have significant effects on sites of international nature conservation importance (Ramsar sites and Natura 2000 sites – Special Areas of Conservation (SACs), Special Protection Areas (SPAs)) in the Hampshire area, a Habitats Regulations Assessment (HRA) is being carried out in parallel with this SEA. The HRA is required under the EU Habitats Directive (EU Council Directive 92/43/EEC on the Conservation of Natural Habitats and Wild Fauna and Flora) and the EU Birds Directive 2009/147/EC (on the Conservation of Wild Birds), and the transposing U.K. Regulations (The Conservation of Habitats and Species Regulations, SI 2010 No. 490). The HRA will be integrated with the SEA process and the conclusions of the HRA will be provided in the SEA Environmental Report. 1.5 Water Framework Directive (WFD) Assessment The Water Framework Directive (WFD) ii is a European Directive which introduces a new strategic planning process to manage, protect and improve the water environment. It came into force on 22 December 2000 and was transposed into UK law in 2003. The Directive will help to protect and enhance the quality of: • surface freshwater (including lakes, streams and rivers); • groundwaters; • groundwater dependant ecosystems; • estuaries; and • coastal waters out to one mile from low-water. It establishes a framework for the protection of water bodies (including terrestrial ecosystems and wetlands directly dependent on them) which aims to; • prevent deterioration in the classification status of aquatic ecosystems, protect them and improve the ecological condition of waters; • achieve at least ‘good’ status for all waters by 2015. Where this is not possible, ‘good’ status should be achieved by 2021 or 2027; • promote sustainable use of water as a natural resource; • conserve habitats and species that depend directly on water; Doc no: 0 Version: 1 Date: 17 Sept 2012 Filename: LFRMS SEA 2nd draft Scoping Report 25,9,2012 2 Hampshire LFRMS SEA: Scoping Report • progressively reduce or phase out release of individual pollutants or groups of pollutants that present a significant threat to the aquatic environment; • progressively reduce the pollution of groundwater and prevent or limit the entry of pollutants; and • contribute to mitigating the effects of floods and droughts iii The LFRMS needs to be assessed for WFD compliance to ensure that local measures to reduce flood risk comply with the WFD, and should contribute to achieving WFD objectives. The WFD is aimed at protecting physical, chemical and biological water quality. The LFRMS is unlikely to need a detailed WFD Assessment. The Environment Agency has advised that ‘WFD assessment can be incorporated into the SEA’ iv . Therefore, the SEA Objectives covering water quality, resource availability and hydromorphology and their underlying assessment criteria are designed in order to fulfil the requirements of the WFD. In general, the spirit of the WFD is to work with natural processes or soft engineering solutions to flood management, rather than hard engineering.
