Chapter 6: Developing Sustainable Communities

Managing change

6.1 The Government is committed to the creation of sustainable communities – that is, creating and maintaining places where people want to live and stay. To achieve this, and realise the vision of the Planning Strategy, we have prepared an overall framework for managing change in the town up to 2028, supported by more detailed policies dealing with different aspects of change.

6.2 This policy will be supported by more detailed design policies in the Development Management Plan.

Addressing climate change

6.3 Climate change is likely to result in wetter, warmer winters and drier, hotter summers, along with a rise in sea levels. Summer rainfall in the South East is projected to decrease by 8% in the 2020s, 19% in the 2050s and by 23% in the 2080s¹⁷.

6.4 The planning system is able to ensure that the design and location of development proposals take into account the need to adapt to future climate change through both its ability to grant planning permission and the allocation of suitable development sites in plans. In particular, planning has a role in:

• ensuring inappropriate development does not take place in areas at high risk of river or sea flooding;

• ensuring development does not make water shortages and drought worse;

• helping to manage high temperatures, particularly in urban areas through protection and management of urban greenspace; and

• controlling the spatial design of new development, such as its layout and orientation.

6.5 In Hastings, we intend to take a pro-active approach to reducing the town’s carbon emissions, and ensuring sustainable development and high quality design are at the heart of our approach to plan making and development management. It may be appropriate in the longer term to look beyond the Borough boundary to meet our energy requirements, and consider the potential for water-based energy from the sea such as wave and tidal power. We also recognise that existing buildings too, can add to the town’s overall carbon emissions and therefore these should be considered in any strategy towards dealing with climate change. Private and community energy generation or water harvesting also has the potential to reduce utility bills and fuel poverty. We will encourage the installation of renewable energy and micro-generation technologies and energy and water efficiency measures within existing development

6.6 We are committed to providing an additional 3,400 homes and significant levels of commercial development up to 2028. We therefore need to reduce our carbon dioxide (CO₂) and other greenhouse gas emissions, in line with the targets set in the Climate Change Act 2008, and to offset the additional (approximate) 3,000 tonnes projected to result from the planned development in the town over the next 15 years¹⁸.

6.7 Climate change mitigation and adaptation measures such as micro-generation, green roofs and walls, sustainable drainage systems, networks of green spaces, the protection and enhancement of biodiversity, waste reduction and recycling, and flood risk management are all now essential components of good planning and design along with the more traditional concerns such as sense of place, local distinctiveness and designing out crime.

Working towards zero carbon development

6.8 Whilst we recognise the importance of micro-generation technologies in reducing harmful gas emissions, this overall strategy seeks to implement an energy hierarchy by achieving energy efficiency first, before looking at implementation of other forms of renewable energy generation on a larger scale. The Hastings Renewable and Low Carbon Energy Study (2009)¹⁹ did not identify any sites as being suitable for exceeding national standards for sustainable building set by either the Building Regulations or the Code for Sustainable Homes. Our policy therefore concentrates on how best to achieve low carbon development in line with the requirements set by the Code for Sustainable Homes and the step-by-step tightening of the Building Regulations. The national timetable for this is as follows:

Year	Target	Private Sector	Public Sector
2008	The Code became mandatory 1 May 2008	Rating now mandatory	Level 3 mandatory
2010	Code Level 3 - A 25% improvement in energy efficiency compared to Part L of the Building Regulations 2006	Level 3 mandatory	Level 4 mandatory
2013	Code Level 4 – A 44% improvement in energy efficiency compared to Part L of the Building Regulations 2006	Level 4 mandatory	Level 6 mandatory
2016	Code Level 6 – Zero Carbon homes	Level 6 mandatory	Level 6 mandatory

Heat density opportunity areas

6.9 Although it is intended that zero carbon homes and carbon reduction in other non-residential buildings will be delivered through national building regulations, it is critical that the local planning system helps to direct the shift needed towards low carbon development and communities.

6.10 Through heat mapping, the Hastings Renewable and Low Carbon Energy Study (2009) identified two high heat demand areas of the town:

• Conquest Hospital

• Summerfields Sports Centre

6.11 Development in these areas could present opportunities for the introduction and expansion of Combined Heat and Power (CHP) systems and district heating networks into the existing build stock.

6.12 There may also be a further opportunity to support the introduction of district heating in the town centre. We will continue to explore options for further heat density opportunity areas, and these will be identified in the Development Management Plan.

Renewable energy schemes

6.13 The Hastings Renewable and Low Carbon Energy Study (2009) assessed the town’s potential to provide large scale renewable energy.

6.14 The study concluded that approximately 4-5MWe (Megawatts electricity) of large scale wind power will be required to offset the carbon emissions resulting from planned development in the town, taking account of the strengthening of the government’s sustainable building standards.

6.15 In response to this, the study identified potential for wind energy in both Combe Valley Countryside Park (within both the Hastings and Rother areas) and at Hastings Country Park. This is in addition to the planned 2MW (megawatt) turbine at the Queensway Employment Corridor.

6.16 Reliability on the local biomass resource (conifer, non-coniferous, mixed and coppice woodland resources) is limited due to inaccessibility within the borough boundary, and competition in the surrounding area, for example, surrounding rural areas have much more available woodland.

(1) 6.17 The Council will therefore take a positive approach to delivering renewable energy developments within the town, and will work in partnership with Rother District Council in considering and identifying sites in urban fringe areas.

Flood risk and water quality

6.18 The 2008 Strategic Flood Risk Assessment (SFRA)²¹ identifies that flood risk in Hastings is attributed to several sources. These include tidal and river flooding, groundwater and sewer flooding, and surface water run off. The most significant flood risk problem exists towards the west of the town around the Bulverhythe area, where groundwater, surface water run-off and tide locking combine to create high levels of flood risk. Higher flood risk areas are also mostly apparent along the Seafront, and around the Hollington Stream and Combe Haven River.

6.19 The SFRA identifies the areas that are affected by groundwater flooding risk, and the extent of the minor aquifers. As this covers a significant area of the town, it is important that these resources are protected from the risks posed by any new large scale commercial development, particularly in West St Leonards and central parts of the town. The Development Management Plan will set out potential development sites in vulnerable areas that could impact on water quality, and consider the measures that need to be taken.

6.20 The Cuckmere and Sussex Havens Catchment Flood Management Plan (2009) and the Hastings Surface Water Management Plan (2011) both highlight that surface water flooding is likely to increase, with further action in the future required to reduce the impacts of climate change. Without future reductions in the amount of surface water generated, the economic and physical development of the town could be compromised. Sustainable Drainage Systems should therefore be designed to provide additional capacity to store run off.

6.21 It is acknowledged that Hastings is within an area of ‘water stress’ as defined by the Environment Agency, and that we must continue to work towards reducing water consumption in the town. Compulsory water metering and changes to the Building Regulations will restrict water usage and assist in reducing current demand. Measures within Policy SC2 also seek to ensure that all new development is designed to incorporate water efficiency measure to reduce demand on water supply.

Coastal change

6.22 The South Foreland to Beachy Head Shoreline Management Plan First Review (2006)²² explores how climate change and natural processes will shape the shoreline over the next 100 years, and the implications this will have on coastal management. For the coastal strip along Hastings Seafront to Bulverhythe and Glyne Gap, the long term policy is to ‘hold the line’ to prevent flooding and erosion of the seafront, and protect economic, tourism and residential assets.

6.23 For the section of the coast from Fairlight Cove to Hastings, the policy is ‘no active intervention’, allowing natural cliff retreat. There is no existing or planned development within this area.

6.24 In view of the above, the Council does not consider it necessary to identify a Coastal Change Management Area in addition to the work undertaken on the Shoreline Management Plan.
