1. Introduction

1.1 Background Pendle Borough Council has commissioned Entec to undertake a Strategic Flood Risk Assessment (SFRA) to provide a detailed understanding of flood risk across the Borough of Pendle. This assessment will inform future strategic planning decisions, and specifically aid in the assessment of future development and sustainability in the Borough in line with PPG25 and the consultation draft of PPS25 Development and Flood Risk. The adopted Joint Lancashire Structure Plan (March 2005) seeks balanced development across the county. It emphasises urban regeneration, with development concentrated in town centres, inner urban areas and the recycling of brownfield land, with less and less need for greenfield development. In East Lancashire, targets are set for a faster rate of housing growth and development of new business and industrial land than would have occurred under existing demographic trends. This proposed level of growth could potentially have significant implications on flood risk across Pendle Borough.

1.2 Scope This study is being carried out in two stages: • Stage 1 which includes the collection and review of baseline information to carry out the SFRA; • Stage 2 which focuses on identifying and characterising the sources of flood risk, and assessing this risk in potential development areas. This report covers Stage 1 of the Pendle SFRA. The aims of Stage 1 were: • To review the baseline data obtained for the study, assess its suitability for use within the SFRA, and identify any data gaps; • To identify any further information that might be required to undertake the SFRA. A meeting with the key consultees will also be held on completion of Stage 1 to review the information available to the study, and to clarify the scope of the final SFRA.

1.3 Structure of the Report This report comprises four sections: • Section 1 provides an introduction to the report;

• Section 2 outlines the planning guidance that will inform the SFRA;

h:\projects\hm-250\18108 pendle sfra\docs\stage 1 report\rr037i3.doc 4 September 2006 © Entec

• Section 3 summarises the flood risk information available, including a review of the data and its potential use in the SFRA, as well as any identified information gaps;

• Section 4 summarises the conclusions and recommendations of this report.

2. Planning Overview

2.1 Introduction Flood risk is one of many planning considerations which have to be balanced when making land use decisions. The challenge for an SFRA is to develop pragmatic solutions that take into account the different requirements of all policies from the national, regional and local level, and to deliver guiding principles to steer future development in a sustainable manner whilst mitigating flood risk. For the purpose of this report, the documents considered for the planning review have been outlined under three headings starting at a higher level (national and regional) down to the local level which has more specific legislation and guidance relevant to Pendle Borough Council. The core documents which are to be considered are outlined below.

2.2 National Level

2.2.1 PPG25 and PPS25 Development and Flood Risk The introduction of PPG 25 in July 2001 reinforced the responsibility that Local Planning Authorities (LPAs) have to ensure that flood risk is understood and managed effectively using a risk based approach as an integral part of the planning process. It introduced the concept of the Sequential Test to guide development away from areas of high flood risk. A consultation draft of PPS25 was published in December 2005 to strengthen planning policy on development and flood risk as part of the Government’s overall approach to managing future flood and coastal erosion risks. The aim of PPS 25 is to provide clarity on what is required at regional and local levels to ensure that decisions are made at the most appropriate level and in a timely fashion to deliver sustainable planning for development and flood risk. The ODPM aim to publish the new PPS 25 summer 2006.

2.2.2 Other Planning Policy Statements and Guidance PPS 1 Delivering Sustainable Development published in February 2005 sets out the overarching planning policies for the delivery of sustainable development across the planning system and sets the tone for other planning policy statements that will follow. PPS 1 explicitly states that development plan policies should take account of flooding, including flood risk. Whilst not directly relevant to the development of a SFRA, it is important to recognise that the exercise takes place within the context of other planning policy statements, some of which also require sequential testing of site allocations and development proposals. PPG 3 Housing, PPG 4 Industrial and Commercial Development and Small Firms and PPS 6 Planning for Town Centres are intrinsic within the planning process, and therefore an understanding of the constraints faced as a result of this additional policy guidance is imperative.

h:\projects\hm-250\18108 pendle sfra\docs\stage 1 report\rr037i3.doc 4 September 2006 © Entec

2.2.3 Making Space for Water During 2004, Defra undertook a consultation exercise, the object of which was to engage a wide range of stakeholders in a debate on the future direction of flooding strategy. The aim was to balance the ‘three pillars’ of sustainability, managing flood risk and ensuring that the social and economic benefits which accrue from growth and development are attained.

2.3 Regional Level

2.3.1 The North West Plan A draft Regional Spatial Strategy (RSS) The North West Plan was submitted to the Government in January 2006. This has since been subject to consultation and will be subject to an independent examination in autumn 2006. The draft provides a framework for the physical development of the region over the next 15 to 20 years. Incorporating the Regional Transport Strategy (RTS), it addresses the scale and distribution of future housing development and sets priorities for dealing with environmental issues, transport, infrastructure, economic development, agriculture, minerals and the treatment and disposal of waste. The draft plan recognises the need for catchment-based sequential water management systems and includes a number of policies designed to reduce current and future flood risk and enhance flood defences. It acknowledges the role that climate change can play in increasing flood risk, and notes the potential impacts of changing groundwater levels due to the cessation of mineral extractions.

2.3.2 Joint Lancashire Structure Plan 2001-2016 The role of the Structure Plan is to provide the strategic planning framework which will guide decisions on development, transport and environmental matters in Lancashire. It was jointly prepared by Lancashire County Council, Blackburn with Darwen Borough Council and Blackpool Borough Council and was adopted in March 2005. When it was written it was intended to remain in place until 2016, but subsequent changes to the planning system mean that it will cease to form part of the development plan in September 2007. The Structure Plan considers flood risk on a whole-catchment basis rather than just being confined to areas of high flood risk. It identifies a sequential approach to flood risk and development.

2.3.3 Regional Flood Risk Assessment The Environment Agency (North West region) in consultation with the North West Regional Assembly (NWRA) is currently producing a Regional Flood Risk Assessment (RFRA) for the North West in response to the RSS and (draft) PPS25. This report is likely to be available in late 2006. As a regional exercise it will primarily consider the order of risks from potential flood sources in relation to present populations and planned future growth.

2.3.4 Meeting the Sequential Flood Risk Test – Guidelines for the North West Region In July 2004, the NWRA and Environment Agency (North West region) published guidelines for LPAs in the North West to undertake a Sequential Flood Risk Test (SFRT) to meet the requirements of PPG25. The guidelines set out a step-by-step approach to the SFRT and the technical issues involved. They also include a summary of potential data sources, a suggested content for a Sequential Flood Risk Test document and examples of ‘ground-truthing’ exercises carried out during the development of the document.

2.4 Local Level

2.4.1 The Local Plan The Replacement Pendle Local Plan (2001 to 2016) was adopted in May 2006. It provides the framework for development until June 2009, although some policies may be ‘saved’ and remain effective after this date. The Local Plan reinforces the Government’s approach to flood risk. It notes that national policy is to reduce the risks to people and the developed and natural environment and that climate change is expected to increase risks associated with both coastal and tidal river flooding. The Local Plan therefore directs development away from areas at risk of flooding or where it would increase the risk of flooding elsewhere by reducing the capacity of the floodplain, installing a culvert, or increasing the flow of water onto the floodplain. SuDS are required, as are Flood Risk Assessments (FRAs) where proposed developments are in areas perceived to be at risk of flooding or where they could increase the risk of flooding elsewhere. Throughout the plan is an emphasis on reusing previously developed land – for employment where the hierarchy for development is in protected employment areas followed by development on land formerly used for employment. Residential development is focussed around: “The re-use or conversion of existing buildings within a settlement boundary, the redevelopment of previously developed land within a settlement boundary and then the development of previously undeveloped land within a settlement boundary which is well located in relation to houses, jobs, other services and infrastructure, and is or can be made accessible by public transport, walking or cycling where this does not affect open space, settlement character or natural heritage. The only allocated sites are designed to support the Housing Market Renewal Intervention programme.”

2.4.2 The Local Development Framework Work commenced on the Local Development Framework (LDF) in 2005. A Local Development Scheme was produced in March 2005 and revised March 2006. This sets out the work programme for the next three years.

The Council has started work on a Statement of Community Involvement which sets out the Council’s policy on consultation with the community for both planning policies and planning applications. This will be available for consultation summer 20061 with a view to adopting in summer 2007. Pendle Borough Council has also commenced work on Bradley Area Action Plan, again consultation is due to take place late summer 2006.

2.4.3 Supplementary Planning Guidance In November 2003, Pendle Borough Council adopted guidance on flood risk and SuDS which supports the development plan. It details the sequential approach to flood risk and considers different development types and their impact on potential flood risk. It also sets out provision for securing funding for flood defences from developer contributions. The Indicative Floodplain Map (2002) is published as part of this document.

3. Information Available to the SFRA

3.1 Sources of Information A significant amount of information relevant to flood risk has been sourced for use in the SFRA, predominantly from the Environment Agency and Pendle Borough Council. The information includes a number of hydraulic models and flood studies of some of the Borough’s watercourses, various GIS layers (including the latest Environment Agency flood zones), and topographical data (LIDAR). British Waterways, United Utilities, Yorkshire Water and the Earby and Salterforth Internal Drainage Board (IDB) have also been consulted.

3.2 Topographic Data An accurate Digital Elevation Model (DEM) is an essential tool for providing a good resolution of flood risk mapping. Both LIDAR and aerial survey provide data with relatively high accuracy (2 metre spacing, 0.25 metre vertical accuracy or better) and are suitable to generate a DEM. LIDAR is presently available for almost the whole Borough, with the exception of the Earby and Kelbrook area, although parts of this area have recently been surveyed by the EA. In areas that do not have either LIDAR or aerial survey, NEXTMap data could be used to generate a DEM. It is available for the whole of Britain thus providing full coverage of the Borough, although the data is of lower accuracy (5 metre spacing, 1 metre vertical accuracy). NEXTMap data is not freely available and would need to be purchased if it was required for the study. Ground survey used to develop various hydraulic models of watercourses in the Borough also provides accurate topographic information, however its coverage is limited to model extents (i.e. river channel and some floodplain areas) and is generally only in model format and not a geo-referenced format suitable for mapping flood risk areas. Table 3.1 summarises the topographic data available to the SFRA, its potential use and data gaps that were identified.

3.3 GIS Data A range of GIS data layers have been sourced from both the Environment Agency and Pendle Borough Council for the purposes of the SFRA.

h:\projects\hm-250\18108 pendle sfra\docs\stage 1 report\rr037i3.doc 4 September 2006 © Entec

3.3.1 Flood Zones The flood zones which form the basis of the Environment Agency Flood Map will be key to informing the Pendle SFRA. They are defined as follows with respect to fluvial flooding2: • Zone 3 (High Probability) comprises areas with an annual probability of flooding of 1% (1 in 100) or greater; and • Zone 2 (Medium Probability) comprises areas with an annual probability of flooding of between 0.1% (1 in 1 000) and 1% (1 in 100). All areas outside of Zones 2 and 3 are classified as Zone 1 (Low Probability) which has an annual probability of fluvial flooding of less than 0.1% (1 in 1 000). The current flood zones available for the whole of the Borough are based on JFLOW, a 2D raster flood-routing model, using ‘bare earth’ topography that does not take into account any structures or defences. These flood zones therefore are considered indicative only. More detailed modelling has been undertaken of some of the main watercourses in the Borough (see Section 3.4 Hydraulic Models and Reports) that may be used to define flood risk more accurately. Note that the Environment Agency flood zones do not provide any indication of flood risk due to minor watercourses (i.e. with catchments of less than 3 km2) or other, secondary sources of flooding including groundwater, overland flow, canal and sewer flooding.

3.3.2 Other GIS Data A wide range of other GIS data has also been sourced for the study, primarily to provide background information for assessing flood risk in the Borough and/ or for mapping the outputs of the study. Table 3.2 summarises the GIS data available, it’s potential use, and any data gaps that were identified.

3.4 Hydraulic Models and Reports A number of hydraulic models (predominantly of main rivers) have been sourced from the Environment Agency for the SFRA. These are outlined in Table 3.3 together with reports relevant to each watercourse.

2 The Environment Agency flood zones are also defined for coastal flooding, however Pendle Borough is not at risk from this type of flooding, and so flood zones have only been described in terms of risk from fluvial sources.

3.5 Other Reports Copies of submitted Flood Risk Assessments have been requested from Pendle Borough Council. These may contain information regarding the standards of protection and levels that have been used in recent developments to supplement other available data. The most recent versions of the draft Burnley Nelson and Colne Flood Risk Management Strategy and Catchment Flood Management Plans (CFMPs) for the River Ribble and the River Aire have also been obtained for the study.

3.6 NFCDD The Environment Agency has provided Pendle Borough Council with access to its National Flood and Coastal Defence Database (NFCDD). This database will be particularly useful for informing the SFRA with respect to flood defences in the Borough, including their location, composition, standards of protection and condition. Access to the database has been obtained, and the relevant information abstracted.

3.7 Utilities

3.7.1 Sewer Flooding Both United Utilities (Ribble area) and Yorkshire Water (Aire area) are responsible for sewerage in the Borough of Pendle. Information on flooding from foul, surface and combined sewers is an important part of the SFRA and has been obtained from the water companies.

3.7.2 Reservoirs There are numerous reservoirs in the Borough of Pendle associated with public water supply (United Utilities) and supply to the Liverpool and Leeds Canal. British Waterways have confirmed which reservoirs feed the canal. Information regarding reservoir safety (inspection and maintenance procedures) has been requested from the authorities.

3.8 Additional Information

3.8.1 Earby and Salterforth IDB The Earby and Salterforth IDB have indicated they do not hold any records of past flood events along the Earby Beck. It was confirmed that flooding is a problem however on the agricultural land for which the IDB is responsible.

3.8.2 British Waterways British Waterways have confirmed that the only event known to them at present involving the Liverpool and Leeds Canal was due to heavy rainfall in 2003 which caused the overflow weir to flood at Salterforth, affecting local roads and property.

3.8.3 Planning for Development – HMR Pathfinder Programme One of the objectives of the Pendle SFRA is to inform planning decisions on the location of future development with respect to flood risk. To aid in this process, the SFRA can focus on areas proposed for new or redevelopment, including areas identified as part of the Housing Market Renewal (HMR) Pathfinder Programme. Targeting areas of interest can be useful both in the early identification of flood risk constraints, as well as working towards the PPS25 objective of locating development in areas of low flood risk at all stages of the planning process. The Council have provided information on the preferred Bradley Masterplan, which includes some land in Zone 3 (high probability of flooding). Other potential development areas to be targeted in the SFRA will be discussed and identified at the progress meeting to review this report.

4. Conclusions and Recommendations

4.1 Review of Information Available A range of information was identified and obtained for use in the Pendle SFRA, predominantly from the Environment Agency and Pendle Borough Council. A preliminary review of this information has been undertaken to determine its potential use in the SFRA and to identify any gaps in the information. In summary: • Topography: Good quality topographical data in the form of LIDAR is available for the majority of Pendle Borough. For the Earby Beck area however, only the lesser quality NEXTMap data will be available within the timeframe of this SFRA. • GIS: The latest Environment Agency flood zones, together with other flood risk and basemapping information has been obtained as GIS data layers. Current flood zones however are not based on hydraulic modelling, and do not include the mitigating effects of flood defences. They are therefore considered indicative and may not present an accurate representation of flood risk.

• Hydraulic Models and Reports: Hydraulic models have been developed for most of the main rivers. No information has been identified for the former COWs and ordinary watercourses.

4.2 The Way Forward Whilst quantitative information on flood risk in the Borough is predominantly based on the Environment Agency flood zones and the more detailed hydraulic models of the main rivers, during the information collation stage of this study, significant references to historical flood incidents have been encountered in all three catchments of the Borough (e.g. Earby in the upper Aire catchment, Barnoldswick in the upper Ribble catchment, and numerous locations along Pendle Water). In particular, very limited quantitative information on secondary sources of flooding (including groundwater, overland flow, canal and sewer flooding) has been identified. The challenge of the final SFRA is therefore to present all of this flood risk information, both quantitative and qualitative, into a useful and useable format to inform future planning decisions. Based on the information obtained to date, a meeting with the key consultees was held to review the information available to the study, and to clarify the scope of the final SFRA. This meeting between Pendle Borough Council, the Environment Agency and Entec, based on the draft issue of this Stage 1 report, discussed the best way forward for the Pendle SFRA, Stage 2.

Appendix B Flood Risk Vulnerability Classification 2 Pages

Table B1 PPS 25 Flood Risk Vulnerability Classification

Flood Risk Land Use Vulnerability Classification

Essential Essential transport infrastructure (including mass evacuation routes) which has to cross the area at infrastructure risk, and strategic utility infrastructure.

Highly vulnerable Police stations, Ambulance stations and Fire stations and Command Centres required to be operational during flooding.

Electricity-generating power stations and sub-stations.

Hospitals.

Emergency dispersal points.

Residential institutions such as residential care homes, children’s’ homes, social services homes and student Halls of Residence and hostels.

Gypsy and traveller sites using caravans or mobile homes.

Mobile or park homes for permanent residential use.

Dwelling houses designed, constructed or adapted for the elderly or other people with impaired mobility.

More vulnerable Buildings used for: dwelling houses (except for those in the highly vulnerable classification); drinking establishments; nightclubs; and hotels.

Non-residential institutions such as health services, nurseries and educational establishments, but excluding hospitals.

Landfill and hazardous waste facilities.

Less vulnerable Buildings used for: shops; financial, professional and other services; restaurants and cafes; hot food takeaways; offices; general industry; storage and distribution; non-residential institutions; and assembly and leisure.

Land and buildings used for holiday or short-let caravans and camping, subject to a specific warning and evacuation plan.

Land and buildings used for agriculture and forestry.

Waste treatment (except landfill and hazardous waste).

Minerals working and processing.

Transport infrastructure.

Table B1 (continued) PPS 25 Flood Risk Vulnerability Classification

Flood Risk Land Use Vulnerability Classification

Water Flood control infrastructure. compatible development Water treatment plants and pumping stations.

Sewage treatment plants and pumping stations.

Docks, marinas and wharves.

Navigation facilities.

Ship building, repairing and dismantling, dockside fish processing and refrigeration and compatible activities requiring a waterside location.

Water-based recreation and tourism (excluding sleeping accommodation).

Lifeguard and coastguard stations.

Amenity open space, outdoor sports and recreation and essential facilities such as changing rooms.

Essential ancillary sleeping or residential accommodation for staff required by uses in this category (subject to a specific warning and evacuation plan).

Notes: 1. Based on PPS 25 Development and Flood Risk. 2. This classification is based on advice from the Environment Agency on the flood risks to people and the need of some uses to keep functioning during flooding. 3. Buildings that combine a mixture of uses should be placed into the higher of the relevant classes of flood risk sensitivity. Developments that allow uses to be distributed over the site may fall within several classes of flood risk sensitivity.

1 DG5 is the measure of level of service provided by water companies with respect to properties at risk of sewer flooding. Internal and external refer to whether flooding enters the building or not. 1 in 5, 1 in 10 and 1 in 20 refer to the frequency of flooding not the return period of the rainfall event causing flooding.
