1.0 Introduction

1.1 This document supplements the East Hampshire Level 1 Strategic Flood Risk Assessment (SFRA), October 2018 and supports the East Hampshire Local Plan 2017–2036 (Regulation 18 consultation). The purpose of this document is to demonstrate that proposed site allocations in areas of flood risk are appropriate in the context of the Sequential Test which are required as part of the National Planning Policy Framework (NPPF) and its accompanying National Planning Practice Guidance (NPPG). However, as this is the first public consultation on the East Hampshire draft Local Plan, the Exception Test has not been carried out at this stage (Regulation 18) as allocations may be subject to change. Those allocations that may require an Exception Test prior to the Proposed Submission Local Plan 2017-2036 (Regulation 19) will be carried out at that time.

1.2 The East Hampshire Local Plan covers the area of East Hampshire outside of the South Downs National Park. This area is known as the Planning Authority area (the ‘Area’). The SFRA 2018 therefore covers the Planning Authority area only but during its preparation neighbouring authorities were consulted to address any cross boundary flood issues to inform the SFRA.

1.3 The aim of the Sequential Test is to steer developments to areas of lowest flood risk from all sources. It has also been used to help inform the sustainability appraisal (SA).

1.4 Sites where an exception is made must then pass the Exception Test to show that there are overriding sustainability reasons for allocation and that they can be developed safely without increasing offsite flood risk. All the sites assessed in the Land Availability Assessment (LAA) have been sequentially tested but as stated above, see paragraph 1.1, the exception test has not been carried out at this stage (Regulation 18).

1.5 This document firstly explains the context in terms of local flood risk and national planning policy. It then sequentially tests all the sites from the LAA and identifies those proposed site allocations that will need a Level 2 SFRA and are likely to need to pass the Exception test in order to support their allocation in the Proposed Submission Local Plan 2017-2036 (Regulation 19).

1.6 Further information relating to the explanation of Sequential/Exception Tests and when they are applicable in relation to the vulnerability of the proposed use is available in the NPPF and its accompanying NPPG.

2.0 Background 2.1 East Hampshire District Council’s Level 1 SFRA 2018 was used to identify where flood risk issues occur across the Planning Authority area (outside the South Downs National Park). This included current Environment Agency flood maps and data covering all sources of flooding (where available)1. This information was considered in the LAA site assessments and the sustainability appraisal to help identify developable land, and subsequent allocations in the draft Local Plan.

2.2 It is important to note that detailed site-specific Flood Risk Assessments will still be required to accompany individual planning applications and remain an important part of the planning application process for all the sites identified in this document.

3.0 Local Flood Risk Context

3.1 There are eleven main rivers located within the Planning Authority area and four named ordinary watercourses. The catchment of the River Wey and tributaries covers a large area in the north. Parts of the Planning Authority area are therefore at risk of fluvial flooding and are designated within Flood Zones 2 and 3 by the Environment Agency. Flood risk is categorised as low to moderate in the northern part of the Planning Authority area (around Alton) in the Thames Catchment Flood Management Plan (CFMP). In the South-East Hampshire CFMP part of the district (around the south west of the Planning Authority area) the main source of flooding is from groundwater sources; however, the Environment Agency categorise the risk as low to moderate. In the south east of the Planning Authority area, in the Arun and Western Streams Catchment, the flood risk is classed as an area with low to moderate flood risk in the rural areas.

3.2 All of the CFMPs highlight that flood risk will increase over time and that the current approach to flood management will need to be kept under review in order to adequately manage flood risk going forward.

3.3 To summarise, East Hampshire is susceptible to flooding from sources other than fluvial, including groundwater and surface water flooding. Much of East Hampshire is underlain by chalk, and recent research tends to suggest that chalk aquifers are more prone to groundwater flooding than other aquifers.

3.4 Modelling studies have shown that climate change will not markedly increase the extent of river flooding within most areas of the Planning Authority area2. However, it is important to note that these areas, as well as those areas that are currently at risk of flooding may be susceptible to more frequent, more severe flooding in future years. The current approach to flood management will need to be kept under review in order to adequately manage flood risk going forward.

1 The Council is aware that since publication of the SFRA October 2018 the UKCP09 projections have now been updated to UKCP18 model outputs. Surface water projections have also been updated but are not yet released. Any FRA will need to take account of the new UKCP09 projections and surface water projections (when available). 2 SFRA October 2018

4.0 Planning Context

4.1 The NPPF provides the policy guidance in relation to development and the allocation of development sites in areas at risk of flooding. The key policy message is to guide new development to areas with the lowest probability of flooding applying the Sequential and Exception Tests as appropriate. The suitability of a site for a particular development should be determined by taking into consideration the Flood Zones (as defined by the Strategic Flood Risk Assessment and the Environment Agency), the flood risk vulnerability of the land use proposed and the sources of flooding. Where it is not possible to locate new developments in areas of lowest flood risk, then clear justification for that allocation must be provided stating the sustainability criteria that are believed to outweigh the flood risk issues of the site, and demonstrate that the proposed development can be developed safely without increasing off site flood risk. This will be informed by the SA and a Level 2 SFRA.

4.2 At the local level East Hampshire District Council is preparing a new Local Plan that will set out a vision and strategy, together with strategic policies to guide development in the Planning Authority area until 2036. This interim supplement supports the Local Plan by sequentially testing the LAA sites. The new Local Plan includes a strategic policy which deals with flood risk (Policy S25 Managing Flood Risk).

4.3 Land Availability Assessment (LAA) The LAA identifies land available for all types of development. Flood risk has been considered as part of the assessment of available LAA sites using the Level 1 SFRA. Those sites that entirely lie within Flood Zones 2 and 3 although considered unsuitable for residential development have been considered for alternative less vulnerable uses. Some sites where only a part of the area is within Flood Zones 2 or 3 have been considered to offer some potential for development subject to further assessment.

Sustainability Appraisal/SEA (SA) 4.4 The SA is the tool for assessing the sustainability of sites. The sequential test has been used to help inform the sustainability appraisal (SA). The SA will assess the sustainability criteria and explain the decisions made for the proposed site allocations. This sustainability criteria will be used to inform the Exception Test, where necessary, at the next stage of the plan-making process.

5.0 Sites Requiring Sequential/Exception Test

5.1 Table 1 identifies those sites which have been brought forward from the development plan and do not currently have planning permission; Table 2 shows those sites from the LAA which are proposed to be allocated for development in the East Hampshire draft Local Plan; and Table 3 identifies all the reasonable alternative sites which are considered to be developable but are not proposed allocations.

5.2 A total of 269 potential LAA sites underwent the Sequential Test as set out in the accompanying Appendix 1. Appendix 2 shows the methodology and scoring criteria used. The Sequential Test looked at all sources of flooding.

5.3 Any proposed allocated site that has secured planning permission has been excluded from this document on the basis that matters relating to flood risk have been thoroughly investigated and found acceptable. Appendix 3 lists those sites that have planning permission.

6.1 With the exception of a small number of sites the Council has been able to allocate the vast majority of development in Flood Zone 1 or in areas free from a designated Flood Zone but may still be prone to either surface water2 or potential groundwater3 flooding which can be mitigated through design.

6.2 Of those sites allocated for development on land in Flood Zones 2 and/or 3 this document has demonstrated that the Sequential approach outlined in the NPPF has been undertaken and met. However, as stated in paragraph 1.1, to date the Exception Test has not been carried out for the reasons stated. For all sites, detailed Flood Risk Assessments will remain a necessary and important part of the planning application process. Applicants, as part of any FRA may need to provide a geotechnical site investigation including site percolation tests to support any potential SUDS proposals.

2 The 1 in 1000 extent was used for the surface water flooding because it allows for an estimation of climate change and gives a conservative worst-case estimate of the impact of surface water flooding on the site.

3 Only the groundwater flooding at the surface was used. This is because at the surface groundwater flooding is deemed to be the risk that is much more constraining on the development than below ground flooding. Below ground flooding can be managed through mitigation such as avoiding basements and using non-return valves and lining foul sewers. The BGS groundwater flooding data was used which shows potential areas at risk rather than actual areas that have flooded from groundwater at the surface.

Appendix 2 – Sequential Test Methodology and Scoring Criteria

Sequential Test Methodology

Step Step Description 1 The main flood hazards that will affect flood risk were assessed for each site. These were fluvial flooding, surface water flooding and groundwater flooding. 2 Worst risk for each model was recorded for each site. 3 Where the majority of a site is affected by one particular risk an 'L*' was recorded next to the hazard. This indicates that this particular risk is likely to provide a restraint to development. 4 Where only a tiny area of the site was flooded by a particular source an 'S*' was recorded next to the hazard. This is because regardless of the frequency of the flooding, the area that floods can be easily avoided through good site layout so is not expected to be a noticeable constraint to development. 5 Each risk score from each hazard was added together which resulted in an overall score which listed the sites from highest to lowest risk. The 1 in 1000 extent was used for the surface water flooding because it allows for an estimation of climate change and gives a conservative worst case estimate of the impact of surface water flooding on the site. Only the groundwater flooding at the surface was used in the ranking. This is because at the surface groundwater flooding is deemed to be the risk that is much more constraining on the development than below ground flooding. Below ground flooding can be managed through mitigation such as avoiding basements and using non-return valves and lining foul sewers. 6 Where a residential development would trigger an Exception Test this was indicated as a yes in the Level 2 SFRA triggered column. This is in accordance with the NPPF planning Practice Guidance table 3. Scoring Criteria
