This document represents a site-specific FRA for the proposed development. The Agency’s guidance supports the NPPF and specifies the requirements for FRAs based on the level of flood risk and the vulnerability of the proposed development to flooding. 1.2 Planning Policy and Guidance In addition, Environment Agency consent is required for any proposed works or structures, in, under, over or within This Flood Risk Assessment has been undertaken with due regard to the following national and local planning policy eight metres of the top of the bank of the watercourse, designated a ‘main river’, (or sixteen metres in the case of a and flood risk guidance. tidal watercourse).

1.2.1 National Planning Policy

1.2.3 Local Policy and Guidance The National Planning Policy Framework (NPPF)1 and associated Planning Practice Guidance for Flood Risk2 aim to steer new development to areas with the lowest risk of flooding. The following documents provide local flood risk policy and guidance for development within the city of Portsmouth:

New development must also ensure that flood risk is not increased elsewhere, and where appropriate, planning applications should be supported by a site-specific Flood Risk Assessment.  The Partnership for Urban South ’s Strategic Flood Risk Assessment (SFRA)4 and Portsmouth City Council’s Local Flood Risk Management Strategy (LFRMS)5 present details of the regional hydrology, potential The NPPF recommends that development should only be allowed in areas at risk of flooding where the FRA (and sources of flooding across the city and implications for developers. the sequential and exception tests, as applicable) can demonstrate that:  Policy PCS12 of Portsmouth City Council’s Core Strategy6 relates to flood risk and includes the following relevant

statements: a) within the site, the most vulnerable development is located in areas of lowest flood risk, unless there are overriding reasons to prefer a different location. The city council will reduce flood risk by following the flood risk management hierarchy set out in PPS25. The

1.3 Site Location Southsea The application site is located off Clarence Esplanade, Southsea, Portsmouth, PO5 3AD, as shown on the Site Location Plan within Appendix 1 and Figure 1 below. The application site is represented by the existing hoverport terminal on the Solent coastline, approximately 1km west of Southsea town centre and 1.5km south-west of Portsmouth city centre.

The Environment Agency’s on-line flood map for planning indicates that virtually the entire application site lies within Flood Zone 3 (high probability of flooding) associated with tidal flooding from the sea. Figure 1. Site Location (image extracted from Portsmouth City Council’s LFRMS)

The National Planning Policy Framework (NPPF) and associated technical guidance confirms that all applications 1.4 Topography and Existing Land Use for proposed new development within Flood Zone 2 or 3 and development proposals exceeding one hectare within Flood Zone 1 must be accompanied by a site-specific Flood Risk Assessment. The application site is located on the relatively flat, low-lying Solent coastline at Southsea. Ordnance Survey mapping indicates ground levels in the vicinity of the application site of approximately 4mAOD, rising slightly into Southsea to the East.

A topographic survey is available for the application site and a copy is included as Appendix 2. The site survey confirms that ground levels are relatively consistent across the application site, and in the range 3.3 to 3.5mAOD. Ground levels within the area of proposed development are approximately 3.3 to 3.4mAOD. The existing land use comprises the Southsea hoverport terminal, with the area of proposed development (extension) comprising shingle beach.

The application site is bound to the north-east by Clarence Esplanade, to the north-west by Pavilion, to the south-west by the Solent and to the south-east by the landing stage.

1.5 Geology

British Geological Survey mapping indicates that the local geology beneath the application site comprises sand, silt and clay of the Palaeogene Earnley Sand Formation and Marsh Farm Formation, overlain by superficial Storm Beach Deposits (gravel)7.

The area of proposed development is located on the shingle beach, where incident rainfall will infiltrate to ground.

1.6 Hydrological Features

The application site is located on the South Coast at Southsea, Portsmouth, adjacent to The Solent. There are no watercourses or other surface water features in the vicinity of the application site.

The local hydrological site setting is presented as Figure 2.

1.7 Proposed Development and Flood Risk Vulnerability Classification

The proposed development comprises a two-storey extension to the Griffon Hoverwork’s existing Southsea Hoverport Terminal building. The extension has a footprint of approximately 36m2 and will provide offices, a meeting room, WCs and kitchenette; proposed site layout plans are included within Appendix 3.

In terms of flood risk vulnerability classification, development associated with docks, marinas and wharves and water-based recreation is classified as ‘water-compatible’ development. This is discussed further in Section 2.3.

2.0 Flood Risk Assessment

2.1 Sources of Information

In addition to the flood risk planning policy and guidance outlined in Section 1.2, the following sources of information have been consulted during the preparation of this FRA:

 Environment Agency website – for information regarding surface water, reservoir and fluvial/tidal flood risk and outline flood zone maps.

The Environment Agency has been consulted for site-specific flood risk information including a detailed flood zone map, predicted flood water levels, details of local flood defences and historic flood outlines; no response had been received at the time of reporting.

2.2 Flood Hazard

All potential sources of flooding to the application site are considered within this section of the report.

2.2.1 Environment Agency Flood Zone Map and Fluvial/Tidal Flood Risk

8 The Environment Agency flood zone map presents information regarding the fluvial and tidal flood risk to the Figure 3. Environment Agency Flood Zone Map application site and is included as Figure 3 below. The flood zone map indicates that the application site is partially within Flood Zone 3 associated with flooding from the sea. Flood Zone 3 is defined as having a high probability of flooding and comprises land assessed as having a 1-in-100 (1%) or greater annual probability of river flooding or a Figure 4 presents an extract of the Environment Agency’s flood risk map for river and sea flooding, which takes into 1-in-200 (0.5%) or greater annual probability of sea flooding. account the presence of any flood defences. This confirms that the footprint of proposed development (outlined in

green) lies predominantly within an area of negligible flood risk but the south-eastern boundary encroaches into an area of high flood risk (greater than 3.3% annual probability of flooding).

2.2.2 Other Potential Sources of Flooding

The local SFRA, LFRMS and online flood maps have been reviewed to identify any other potential sources of flood risk to the application site and evidence of historic flood events in the local area. This information is presented in Table 1 below.

Table 1: Southsea Hoverport – Potential Sources of Flooding Potential Risk Potential Source at Application Reasoning Site? There are no watercourses in the vicinity of the application Fluvial Flooding No site.

The Environment Agency’s flood zone map for planning Tidal Flooding Yes indicates that the application site is located partially within Flood Zone 3 associated with sea flooding. Figure 20 of the LFRMS confirms that the application site is not within a target area or region for groundwater flood risk management. Flooding from High The application site is coastal where the risk of No Groundwater groundwater flooding is generally negligible. The SFRA online map confirms there are no recorded Figure 4.

Site-specific predicted flood water level data has been requested from the Environment Agency but has not been The Environment Agency’s online mapping confirms that Surface Water received at the time of reporting. No the application site has a very low (<0.1% annual Flooding probability) of surface water flooding. However, review of the flood extent (Figure 4) and the site topography (Appendix 2) indicates a predicted flood The application site is coastal with drainage from the water level of approximately 3.4mAOD for the high risk (>3.3% annual probability) scenario. The existing ground limited surrounding development assumed to discharge to levels within the area of proposed development are 3.3 to 3.4mAOD, indicating a potential flood water depth of approximately 0.1m. It is uncertain, from existing data, if flood water depths would be higher during less frequent Flooding from sea. flood events and this should be confirmed following receipt of Environment Agency site-specific flood data. Artificial Drainage No The SFRA online map confirms there are no recorded Systems sewer flooding incidents in the vicinity of the application

site. Online mapping from the 2016 PUSH SFRA, includes details of local flood defence infrastructure. This indicates that the coastal frontage adjacent to the application site offers a standard of protection of between 1-in-50 years (2% annual probability) and 1-in-100 years (1% annual probability), based on 2007 data. Review of the Environment Agency’s online mapping Flooding due to No confirms the application site is not within the predicted Infrastructure Failure However, the application site lies within the Southsea Coastal Scheme, a £100m flood defence scheme of which maximum extent of flooding of local reservoir(s). Phase 1 construction commenced in September 2020. The impact of this scheme on predicted flood water levels within the application site is currently unknown. In the vicinity of the application site the proposed defences include widening the existing beach combined with a stepped revetment defence. Table 1 confirms that the only potential source of flood risk identified within the application site is the risk of flooding from the However, appropriate flood risk mitigation measures for the proposed development are discussed below in Section sea. The tidal flood risk is detailed in Section 2.2.1 and appropriate mitigation measures are discussed below in 2.4. Section 2.4.

 Flood resilient design shall be incorporated within the development to a minimum elevation of 600mm above external ground levels. These measures could include raised electrical sockets, wiring and meters, non-return 2.2.3 Historic Flooding valves on drainage and the use of water compatible flooring and other materials.

Review of the Environment Agency’s online historic flood map confirms that the application site is not within an area  The application site is located within an Environment Agency Flood Warning Area; Griffon Hoverwork shall sign that has previously recorded flooding9. up to the Agency’s free flood warning service and follow published guidance in the event of a flood warning being issued. The application site is located within the Environment Agency Flood Warning Area: Coast at Southsea.

Although there will be a slight increase in impermeable surface area as a result of the development, the application site is on the coastline at Southsea with surface water runoff discharging directly to the sea, with no requirement for 2.2.4 Climate Change attenuation. Therefore, the site’s existing surface water drainage scheme remains appropriate.

It is recognised that peak river flows and sea levels are predicted to increase as a result of climate change, and this must be considered within new development design. The application site lies within the South East river basin district. Review of the Environment Agency’s guidance on climate change allowances10 indicates a potential worse- case sea level rise of between 1.2m (higher central, 70th%ile) and 1.6m (upper end, 95th%ile) from 2000 to 2125.

The Southsea Coastal Scheme flood defence investment project aims to address current and long-term flood risk at Southsea due to future sea level rise. 3.0 Summary and Conclusions

Appropriate flood risk mitigation measures for the proposed development are outlined in Section 2.4. This report represents a site-specific Flood Risk Assessment to support the proposed development of an extension

As set out in the NPPF, the aim of the Sequential Test is to steer new development to areas with the lowest The Environment Agency flood zone map for planning indicates that the application site is partially within Flood probability of flooding. It is recognised however, that the proposed development represents an extension to an Zone 3 (high probability of flooding) associated with flooding from the sea; therefore, a detailed site-specific FRA is existing facility and therefore it is not appropriate to consider potential alternative sites. required.

The Environment Agency’s flood zone map indicates that the footprint of proposed development lies partially within A review of all potential sources of flooding to the application site has been undertaken and no other sources of high probability Flood Zone 3. Table 3 of the Environment Agency’s flood risk assessment guidance3 presents a flood risk have been identified. matrix assessing the appropriateness of new development based on its flood risk vulnerability and flood zone status.

The proposed development of an extension to the existing Southsea Hoverport terminal is classified as ‘water There is no record of historic flooding within, or in the immediate vicinity of the application site. However, the wider compatible’ in flood risk terms and Table 3 of the guidance confirms this to be appropriate development within Flood Southsea area has experienced historic flooding and the application site is within the Southsea Coastal Scheme, a Zone 3. £100m flood defence scheme of which Phase 1 construction commenced in September 2020.

It is acknowledged however, that the application site is coastal and within an area at risk of flooding from the sea, However, due to the risk of tidal flooding from the coast, a number of flood risk mitigation measures are proposed: therefore flood risk mitigation measures are proposed, as outlined in Section 2.4.  The finished floor level of the proposed development will be a minimum of 300mm above external ground levels 2.4 Flood Risk Mitigation Measures (equivalent to a minimum finished floor level of 3.75mAOD).

The following flood risk mitigation measures are proposed for the development:  Flood resilient design shall be incorporated within the development to a minimum elevation of 600mm above external ground levels. These measures could include raised electrical sockets, wiring and meters, non-return  The finished floor level of the proposed development will be a minimum of 300mm above external ground levels valves on drainage and the use of water compatible flooring and other materials. (equivalent to a minimum finished floor level of 3.75mAOD).

 The application site is located within an Environment Agency Flood Warning Area; Griffon Hoverwork shall sign up to the Agency’s free flood warning service and follow published guidance in the event of a flood warning being issued.

The footprint of the proposed development is just 36m2, with surface water runoff discharging directly to the beach/sea and no potential for increased flood risk to others, therefore there is no requirement to review the site’s existing surface water drainage scheme.

Therefore, this FRA concludes that the development of an extension to the existing hoverport terminal at Southsea, classified as ‘water compatible’ development, is appropriate and sustainable with regards to flood risk.
