Roles and Responsibilities for Local Flood Risk Management

Overview Under the Flood and Water Management Act 2010 West Sussex County Council has the responsibility for developing, maintaining and applying a local flood risk management strategy within the county. It is intended that local authorities should reflect the content, guiding principles, aims and objectives of the national strategy in the development of their local flood risk management strategies. West Sussex County Council will not be working in isolation. A range of partner authorities known as risk management authorities also have flood and coastal erosion management duties, powers and responsibility. The development of the local flood risk management strategy required input from designated ‘flood management authorities’. In West Sussex the other flood risk management authorities are the Environment Agency, the five Internal Drainage Boards (Upper Medway, Ouse, Arun, Adur and South West Sussex), the Highways Agency, Southern Water Services Ltd, Thames Water Utilities Ltd and the seven District and Borough Councils. In West Sussex, Southern Water Services Ltd and Thames Water Utilities Ltd are responsible for managing public sewers, and for resolving flooding issues where there is no significant interaction with other types of flooding. The seven District and Borough Councils in the county are an important part of flood risk management are risk management authorities in their own right, and, all take an active role in assisting the Lead Local Flood Authority in performing some Flood and Water Management Act duties.

Figure 9: Who manages what within West Sussex? The Internal Drainage Boards (IDBs) carry out maintenance works within their Internal Drainage District (IDD). Four of the five IDBs are operated by the Environment Agency (the Ouse, Arun, Adur and South West Sussex). The fifth IDB (Upper Medway) covers a small area within the county near East Grinstead and is independently managed. At the time of writing in 2013 an Environment Agency review into the management of Internal Drainage Districts was underway which may change the current set up. Under the provisions of the Flood and Water Management Act the following duties are common to all risk management authorities:  Duty to cooperate with other risk management authorities  Duty to act consistently with the national and local strategies  Powers to take on flood risk functions from another risk management authority  Duty to contribute towards the achievement of sustainable development  Duty to be subject to scrutiny from the Lead Local Flood Authority’s democratic process. Responsibilities of different organisations West Sussex County Council (Lead Local Flood Authority) The responsibilities of the county council as Lead Local Flood Authority and as a risk management authority are to:  Provide leadership of local flood risk management authorities;  Develop, maintain, apply and monitor a strategy for local flood risk;  Permissive power to do works to manage flood risk from surface water runoff or groundwater;  Permissive power to request information from any person in connection with the authorities flood risk management functions;  Permissive power to exercise the Land Drainage Act 1991;  Perform as a Category 1 responder to flood incident under the Civil Contingencies Act 2004, including dealing with recovery and resulting homelessness;  A duty to investigate and publish reports on flood incidents in West Sussex (where appropriate and necessary) to identify which authorities have relevant flood risk management functions, and what they have done or intend to do;  A duty to maintain a register of structures or features that have a significant effect on flood risk;  Permissive power to designate structures and features with flood risk significance;  Responsibility (once enacted) for the sustainable drainage systems approving body with responsibility for approval, adoption, inspection and maintenance of new sustainable drainage systems;  Decision making and enforcement responsibility for whether third party works on ordinary watercourses by third parties, that may affect water flow, can take place;  A duty to contribute towards the achievement of sustainable development in the exercise of flood risk management functions and to have regard to any ministerial guidance on this topic.

Environment Agency The Environment Agency has the following roles and responsibilities as a risk management authority:  A strategic overview of all types of flooding;  Responsible for flood risk management on main rivers and the coast;  A coastline erosion risk management authority, under the Flood and Water Management Act 2010;  Responsible for Environment Agency reservoirs, and, to regulate and enforce the Reservoirs Act 1975 on other reservoirs with capacity over 10000m³;  Duty to be subject to scrutiny from Lead Local Flood Authorities;  Carrying out flood risk management functions in a consistent manor with the national and local strategies, reporting to ministers on flood risk management and implementation of strategies;  Permissive power to request information for any person in relation to flood risk management concerning Environment Agency functions;  Permissive power to designate structures and features with flood risk significance;  To be a statutory consultee to the Sustainable Drainage Systems Approving Body;  To be a statutory consultee to local planning authorities on flood risk matters;  Perform as a Category 1 responder to flood incident under the Civil Contingencies Act;  Consent and enforce applications for works on main river;  A duty to contribute to sustainable development through flood risk management functions. Internal Drainage Boards Internal Drainage Boards have the following roles and responsibilities as a risk management authority:  Carry out maintenance work to maintain drainage;  Use statutory powers to ensure those responsible maintain the flow of water in a watercourse and to modify or remove inappropriate structures within channels. Take the appropriate action against those who inappropriately modify the watercourse;  Responsible for reservoirs over 10000m³ capacity;  Permissive power to exercise the Land Drainage Act 1991;  A duty to contribute towards sustainable development;  Permissive power to undertake flood risk management works;  Undertake consenting on ordinary watercourse within their boundary;  Be a statutory consultee on the Sustainable Drainage Systems Approving Body;  Work alongside and together with neighbouring Internal Drainage Districts;  Duty to be scrutinised from Lead Local Flood Authority democratic processes;  Duty to act consistently with the Local and National Strategy;  Permissive power to designate structures and features with flood risk significance. Southern Water and Thames Water Southern Water and Thames Water have the following roles and responsibilities as a risk management authority:  Duty to adopt new build sewers;  Manage public sewer flooding;  Duty to subject to scrutiny from Lead Local Flood Authority democratic process;  Duty to have regard for the National and Local Strategies;  Perform as a Category 2 responder to flood incidents under the Civil Contingencies Act. The District and Borough Councils (Second Tier Authorities) The Districts and Boroughs have the following roles and responsibilities as a risk management authority:  Permissive power to designate structures and features with flood risk significance;  Duty to act consistently with the Local and National Strategy;  A coastline erosion risk management authority, under the Coastal Protection Act 1949;  Duty to be subject to scrutiny from Lead Local Flood Authority democratic process;  Permissive power to exercise parts of the Land Drainage Act 1991 (except in an Internal Drainage District) area;  Perform as a Category 1 responder to flood incidents under the Civil Contingencies Act 2004, including dealing with recovery and resulting homelessness;  Perform as the local planning authority and a duty to encourage the appropriate development and promote sustainable development;  Under delegated powers, use statutory powers to ensure those responsible maintain the flow of water in a watercourse and to modify or remove inappropriate structures within channels. Take the appropriate action against those who inappropriately modify the watercourse. Highways Agency The Highways Agency has the following roles and responsibilities as a risk management authority:  Duty to have regard for the National and Local Strategies;  Responsibility to maintain the highway trunk road network under the Highways Act (in West Sussex the A23, M23 and A27) and for these roads;  Duty to regularly inspect and maintain highways structures;  Permissive powers to deliver works to protect the highway from flooding (for example, draining roads into private watercourses);  Carry out maintenance and improvement works to maintain existing standards of protection for highways;  A duty to contribute towards sustainable development. Other Stakeholders While not designated flood risk authorities, stakeholders such as infrastructure providers, riparian owners, parishes and residents have a key part to play in flood risk management. Utility and infrastructure providers While not risk management authorities, utility companies play an important role in flood risk management. Many assets of utility companies are in areas prone to flooding. Ensuring that the service the company provides is resilient to flooding can save the company money in the long term, so flooding is an important factor in investment and planning. Companies can achieve savings if they contribute to partnership schemes. This approach provides mutual benefit for those involved and ensures services for the public and businesses are more resilient. Riparian Owners Home or business owners that live close to a river or ditch are likely to be riparian owners with maintenance rights and responsibilities. If the watercourse borders the property it is normal for the boundary of responsibility to extend to half way across the channel. Maintenance responsibilities include keeping the channel clear of obstructions, and maintaining a free flow of water in the watercourse. Land drainage management and maintenance is vital to ensuring that surface water is adequately managed across the county. The key message to riparian owners is, you must let water flow through your land without any obstruction that may affect the rights of others. Importantly, you should keep the banks and bed of the ditch clear of anything that could cause an obstruction and increase flood risk. More details can be found on the West Sussex County Council or Environment Agency websites by searching for ‘riparian ownership’. The Environment Agency’s ‘Living on the Edge’ document provides a full guide and is available online. Risk management authorities take every opportunity to communicate publically about riparian responsibilities. The Parish and Town Councils can play a key role in supporting local knowledge and communicating the rights and responsibilities to communities. If you have a watercourse within your property boundary, such as river, brook, beck, ditch, mill stream or culvert, and are unsure on its maintenance please seek advice via the Living on the Edge document. Full contact details are available should you wish to speak to an advisor. Any works to construct in or over a watercourse or alter the channel may require Ordinary Watercourse Consent. Please contact your local District or Borough Council for more information, or visit the West Sussex County Council website. Parish and Town Councils Town and Parish Councils can make a significant contribution before and during a flood event. Coordinated assistance can be critical in supporting local residents and in providing the shelter for neighbours who have experienced flooding. Parish and Town Council members can also play a crucial role in the dissemination of flood alerts and flood warnings, as they have the local knowledge of the community. This local knowledge can also be used to inform the District or Borough Council or County Council about sources of flooding. An affective Parish or Town Council will have an emergency plan, and an agreed process in place to react to a natural disaster. For more information please contact your District or Borough Emergency Planning Officer who will be able to provide guidance. For other advice please contact the West Sussex County Council Community and Economic Development Team (please see page 60 for areas covered) who will direct your query to the appropriate lead officer. Property owners and residents It is home owners and business owner’s responsibility to protect their property from risks, including flood water protection. It’s impossible to completely flood-proof a property but there are lots of things that can be done to reduce flood damage. More details can be found on the Environment Agency website by searching for ‘prepare your property for flooding’.

PROJECT NUMBER: Manhood Peninsula SWMP – Geology and Hydrogeology

1 Introduction There is a perception that groundwater flow and groundwater levels may contribute to the causes of flooding and flood risk within the Manhood Peninsula SWMP study area. As a result, a more in depth analysis of the groundwater regime has been carried out and is presented here. This encompasses:  A summary of data used for the analysis  A description of the geological setting, both regional and site specific that dictate the occurrence, movement and potential emergence of groundwater  A description of the hydrogeological regime  An analysis of available groundwater and other relevant data  The development of a hydrogeological conceptual model to express characteristics and processes inherent to the groundwater system incorporating a description of groundwater flooding processes 2 Data collection and Collation The data sources specifically referenced for this study are identified in Table 2.1 below.

3 Geology and Hydrogeology 3.1 Geological Setting a) Solid Strata The regional geological setting of the Manhood Peninsula is significantly influenced by its geological structure. The general southerly dip of the Chalk is subject to significant folding comprising primarily the “downfold” of the Chichester syncline and the associated “upfolds” of the Portsdown and Littlehampton anticlines. This is illustrated in Figure 3.1 below.

Figure 3.1 Generalised regional geological section through Chichester and across the Manhood peninsula. Note that some of the geological nomenclature used on the cross section has now been superceded. (From: “The Chalk Aquifer of the South Downs”. Hydrogeological Report Series of the British Geological Survey. British Geological Survey 1999). As a result of this structure the extreme northern part of the study area is underlain by Chalk strata of Cretaceous age, where it has been brought to the surface by folding. In this area the Chalk near the surface is overlain by superficial River Terrace Gravel and Alluvial Fan deposits (see below). The Chalk mapped in this area is undifferentiated between the various different chalks of the White Chalk Sub Group, as described in Table 3.1 below. The Chalk is overlain in turn by younger Palaeogene rocks of the Lambeth Group (Reading Formation), the Thames Group (London Clay Formation) and the Bracklesham Group. The BGS 1:50,000 geological map (Figure 3.2) shows the disposition and distribution of these strata across the peninsula, with the youngest beds occurring beneath the southern part of the peninsula.

2 APPENDIX X GEOLOGY AND HYDROGEOLOGY

TABLE 3.1 Solid geological strata encountered beneath the Manhood Peninsula Formation Lithological Description Selsey Sand Formation Formed in a shallow sea environment the Selsey Sand Formation comprises silty sand, silty clay and sandy clayey silt, up to (Bracklesham Group) about 25m thick. Occurs in the Selsey area at the tip of the peninsula. Marsh Farm Formation Formed in a shoreline environment the Marsh Farm Formation comprises laminated clays, interbeded with fine sands and silts, (Bracklesham Group) about 10-15m thick. Earnley Sand Formation The Earnley Sand Formation comprises greenish silty sands and sandy silts, formed in a shallow sea environment, up to about 25m (Bracklesham Group) thick. Wittering Formation The Wittering Formation is a greyish brown laminated clay with interbedded fine sand and silt. Up to about 40- 50m thick. It occurs (Bracklesham Group) across the southern central part of the peninsula. London Clay Formation The London Clay Formation is a uniform blue marine clay although there may be pebble beds near it’s base. It occurs in the area (Thames Group) around Chichester and across most of the northern and central part of the peninsula, where it may be in excess of 80m deep. There is a narrow band of shelly. Calcareous sandstone (the Bognor Sand Member) that occurs east –west across the north central part. Reading Formation Lambeth Group strata (formerly Woolwich and Reading Beds) occur in the northern part of the area, directly overlying Chalk. The (Lambeth Group) Reading Formation comprises vertically and laterally variable clays, silts and fluviatile fine sands with some sands and gravels. They may be about 30m thick in the Chichester area. Tarrant Chalk Member, The Tarrant Chalk comprises soft, white homogeneous chalks with Culver Chalk Formation nodular flint courses; marl seams are absent except in the basal few metres. Hardgrounds and phosphatic chalks may also occur. (White Chalk Sub Group ) Newhaven Chalk The Newhaven Chalk is characterised by nodular chalks and sponge Formation beds, with well-developed layers of nodular flint. There is considerable variation in thickness and lithology, with marl seams (White Chalk) most strongly developed in the thicker sequences. Seaford Chalk Formation The Seaford Chalk is a soft chalk with frequent hard bands and beds of large flint nodules. Some marl seams and nodular chalks are (White Chalk Sub Group) present in the lower part. b) Superficial (drift) deposits The underlying strata are not exposed at outcrop, and throughout the peninsula are covered by younger, unconsolidated drift (superficial) deposits. These are the result of more recent geological and geomorphological processes (Quaternary age up to circa 3 Million years ago) and comprise a number of different deposits, as described in Table 3.2 below. The age relationships between these deposits is not always clear, particularly between alluvium and tidal flat deposits, although the Table below is arranged in presumed age order (youngest at the top).

APPENDIX X GEOLOGY AND HYDROGEOLOGY 3

TABLE 3.2 Superficial (Drift) deposits beneath the Manhood Peninsula study area Deposit Description Alluvial Fan Deposits Clay, silty, sandy. Fine silt and clay from overbank floods forming floodplain alluvium. Derived primarily from the discharged fluvial deposits of the River Lavant. Found across the northern part of the study area to the south and south east of Chichester. Beach and Tidal Flat Clay, silt, sand and gravel from a shoreline environment (as above). Deposits Occur in a thin strip along the coastline, from West Wittering to (undifferentiated) Pagham Raised Marine Deposits Clay, silt, sand and gravel. Superficial Deposits formed in a shallow sea environment, associated with a period of higher sea levels (see also Raised Beach). Primarily associated with the courses./ immediate area of the Pagham and Earnley Rife. Raised Beach Deposits Sands and gravels from former shoreline deposits associated with higher sea levels from interglacial periods. Found close to the Chichester Harbour shoreline and up into the lower lying areas occupied by the rifes. River Terrace Deposits Sand, silt and clay. Coarser deposits derived from river channel (undifferentiated) detrital material from both existing and fossil river channels. Relatively thin and very permeable. These are found across most the study area, blanketing over the underlying strata. Head Clay, silt, sand and gravel formed primarily as erosional products from subaerial slopes as accumulated material from down slope movements including landslides, debris flow, solifluction, soil creep and hill wash. Isolated occurrence, primarily to the north and east of Birdham and Birdham pool, running south west- north east toward Donnington, with some other small exposure.

The BGS 1:50,000 geological map showing the drift deposits occurring across the study area is provided as Figure 3.3. 3.2 Hydrogeology a) Groundwater Occurrence and Flow Regionally, the Chichester Chalk aquifer is recharged by rain falling on the Lavant catchment, north of Chichester. The synclinal fold structure of the Chalk beneath Chichester, described above, is such that southerly groundwater flow from the recharge area to the north is effectively diverted in both easterly and westerly directions. Significant springs discharging this groundwater emerge at Fishbourne Springs, to the north western end of Chichester Harbour, where the Chalk lies directly beneath a relatively thin and permeable drift cover of superficial deposits. Further springs derived from this regional groundwater flow emerge as far east as Arundel and as far west as Beckhampton. This is illustrated by the conceptual section in Figure 3.4 below.

4 APPENDIX X GEOLOGY AND HYDROGEOLOGY

The effect of this regional groundwater flow pattern in the Chalk is discussed further below.

Figure 3.4. The effect of the Chichester Syncline on regional groundwater flow. (From: “The Chalk Aquifer of the South Downs”. Hydrogeological Report Series of the British Geological Survey. British Geological Survey 1999). The Lambeth Group strata may contain groundwater in limited quantities and more sandy units at the base may be in hydraulic continuity with the underlying Chalk, however it is not considered that these units are likely to generate significant flow toward the surface where they may contribute to baseflow or contribute significantly to groundwater flooding issues. However, where the Reading beds are thin and sandy they may not fully confine the Chalk and allow upward movement of regional (Chalk) groundwater flow. Groundwater may also occur in lesser amounts in the Bracklesham Group Strata and although these formations are heavily interbedded with clays and silts and are unlikely to generate significant regional groundwater flow, there may be local occurrence of groundwater. The London Clay Formation contains little groundwater and acts as a barrier to groundwater flow (as occurs beneath Chichester) confining the underlying Chalk. The extensive superficial deposits that cover the peninsula (see Table 3.2) are dominated by River Terrace Deposits. Although relatively thin (typically not much more than 5m) and laterally and vertically variable, these deposits may comprise coarse sands and gravels which may contain groundwater, possibly at shallow depths (particularly where they lie directly on London Clay). Recharged locally by rainfall, these superficial deposits may contribute to baseflow in drains and channels. Where coarse superficial deposits lie directly over the Chalk, they may provide a flow path for Chalk groundwater to come to the surface (see further below) b) Groundwater and Surface Water Level data analysis Groundwater level information from the Chalk aquifer was available from an EA monitoring borehole at Lagness, about 2km east of South Mundham. The Chalk in this location is at about 20m depth, and the aquifer is confined by the overlying Reading Formation. The level data (groundwater hydrograph) is shown on Figure 3.5 below together with surface water flow (flow hydrograph) measured in Pagham Rife and rainfall (monitored at Fishbourne).

APPENDIX X GEOLOGY AND HYDROGEOLOGY 5

Figure 3.5 Groundwater levels at Lagness, Pagham Rife Flow and Fishbourne rainfall Notably the maximum groundwater levels recorded (at Lagness) each winter for the period of the record appear relatively consistent during each winter, and there is no significant or anomalous peak in the data during the winter of 2013/2014, as has been recorded elsewhere in West Sussex. This is somewhat curious, but may reflect the confined condition of the groundwater in this location and the fact that significant groundwater discharge occurs further north (as described above in section 3.2a). The surface water flow in Pagham Rife (gauged toward its downstream end) may also be compared with groundwater levels at Lagness – the correlation does not appear to be that good (e.g. winter groundwater levels in 2006, 2009, 2010 do not appear significantly different to those from 2014 whereas there is a significant difference in the winter flows in Pagham Rife for these periods (though see note below) ). On this basis, it would therefore appear that flows in Pagham Rife are not that closely related to groundwater levels in the Chalk beneath the northern and eastern part of the peninsula. The relationship between more regional groundwater flow and flows in Pagham Rife is however more revealing. If groundwater monitoring from the Graylingwell monitoring station (north east of Chichester) is compared with Pagham Rife flows, arguably there is a more direct correlation, as shown in Figure 3.6 below. For example, Graylingwell, when considered in the context of seasonal water level fluctuations, shows a markedly lower groundwater level in 2005/2006 than in 2014 (more in line with Pagham Rife Flows) and there appears to be a much better correlation throughout.

6 APPENDIX X GEOLOGY AND HYDROGEOLOGY

Figure 3.6 Pagham Rife Flow vs Groundwater levels at Lagness and Graylingwell This information would seem to suggest that flows in Pagham Rife are quite closely related to the Chalk groundwater and hydrological regime to the north of Chichester and that regional Chalk groundwater flow could contribute to baseflow in the upper (north east) part of the Pagham Rife catchment (i.e. the Forebridge Rife), for example emerging through the River Terrace Gravels east of Runcton. However there does appear to be only a relatively limited reach (circa 1km) through which this could occur, so this direct baseflow contribution from the Chalk to the Forebridge Rife may be relatively limited. This observation of the correlation of baseflow and regional groundwater level may in part relate to groundwater movement through the River Terrace Deposits, recharged by regional groundwater flow and the River Lavant. These River Terrace Deposits follow the historic course of the River Lavant, which used to discharge southward to Pagham Harbour through this route and are (at least) locally significant in maintaining shallow groundwater levels. It is not clear whether operation of the River Lavant Flood Allevation Scheme has had any impact on the flows in the Pagham Rife (as shown in the hydrographs) although we believe that this is not the case. It is understood that under the phased implementation of the scheme, Phase 2, which is to divert flows from the lakes at Church Farm Pit and East Pit (north of the A27) into Forebridge Rife, has yet to be fully implemented. It is understood that to date scheme operation has been based solely on utilizing the attenuation storage provided by the pit lakes and the southerly diversion of the flow has yet to be introduced. Smaller springs along Pagham Rife north of Runcton appear to relate to water in the River Terrace Gravels (underlain by London Clay at this location). These would appear to be primarily the result of local recharge, although there may be an element of regional southerly groundwater flow transmitted through the shallow deposits. Other rifes across the peninsula are largely isolated from the underlying Chalk, although there may be contributions to baseflow in all rifes from groundwater in the superficial deposits (see below).

APPENDIX X GEOLOGY AND HYDROGEOLOGY 7

4 Hydrogeological Conceptual Model and Groundwater flooding 4.1 Regional Groundwater Influence Although the Chalk is present beneath the northern part of the peninsula, it has limited influence on groundwater flow and emergence in the south and central parts of the study area where it is wholly confined by the London Clay and other younger strata. In the north, regional groundwater flow emerges from beneath and around the Chichester syncline through:  Large emergent springs just south of Fishbourne  Possible discharges (through River Terrace gravels) to the Lavant to the west of Stockbridge  Discharge to the River Terrace Deposits and other permeable drift deposits and hence a probable contribution to baseflow the upper reaches of Pagham Rife It is considered unlikely, other than contributions to baseflow, that groundwater in the Chalk contributes significantly to flooding problems in the peninsula. 4.2 Groundwater in superficial deposits Groundwater in the thin but very permeable superficial deposits may potentially cause local issues with groundwater flooding, although our investigations have provided little direct or anecdotal evidence for this occurring. In the central and southern part of the peninsula, this “shallow” groundwater is mostly recharged by local rainfall, and discharges through the extensive network of drainage channels. Given the highly permeable nature of most of these deposits, they are likely to respond quickly to rainfall recharge and discharge relatively rapidly (in groundwater flow terms). To the north there may be a more significant relationship between the underlying Chalk aquifer and the superficial deposits, as described above. Adjacent the main rifes, there may also be greater interaction between the permeable superficial deposits, which could contribute to baseflow, although it is not clear how much this might impact conveyance capacity. Any groundwater derived flooding is likely to be strongly associated with fluvial flooding events (from local land drains, watercourses channels and rifes) and is it is considered unlikely it will be (or has been) reported specifically as groundwater flooding. One exception to this may be the issues related to (groundwater) infiltration into Southern Water sewers in the Selsey area, which is well documented. In this area, although there may be some groundwater in the underlying Selsey Sand formation, it is most likely to be derived from the superficial River Terrace Deposits. This could also be problematic elsewhere in the peninsula, although we have had no reports that could corroborate this. In addition, high groundwater levels in the permeable superficial deposits may prevent the effective use of soakaways and other infiltration drainage. For example, there are a number of soakaways in Stockbridge, and there have been reports of flooding in and around them. Although residents have reported the drains are blocked, potentially these failures may relate to high groundwater levels in the area. In this location, infiltration/ soakway drainage to groundwater could also be influenced by high groundwater levels in the Chalk during winter months (see above) which may prevent them functioning properly.
