  Introduction
5.1 For the most part, the attractive countryside around Preston requires long term protection, because of either the function for which the land is used or its existing natural qualities.
5.2 The main use of land in rural areas is agriculture. Good quality agricultural land is a national asset which must be conserved. Land which is within the Green Belt also performs an important function in checking urban sprawl, so it must also be protected.
5.3 Perhaps the most attractive semi-natural countryside in the City is that within the Forest of Bowland Area of Outstanding Natural Beauty (AONB) but there are other areas of high environmental quality.
5.4 PPG7: The Countryside - Environmental Quality and Economic and Social Development states that: "The guiding principle in the countryside is that development should both benefit economic activity and maintain or enhance the environment". In line with this principle, this section of the plan develops a hierarchy of policies to protect the countryside and special features within it and to limit development to that which is appropriate in certain locations to promote the rural economy. The policies have been drawn up to meet the following objectives:
  Objectives
 
  • TO PROTECT SITES OF ENVIRONMENTAL SIGNIFICANCE.
  • TO MAINTAIN GREEN BELT LAND IN ITS CURRENT OPEN CHARACTER.
  • TO PROTECT THE OPEN COUNTRYSIDE WITHIN THE CITY CONSISTENT WITH SATISFYING THE CITY'S DEVELOPMENT REQUIREMENTS.
  • TO PROTECT THE ENVIRONMENT AND AMENITY OF THE COUNTRYSIDE WHILST CATERING FOR A REASONABLE LEVEL OF SMALL SCALE DEVELOPMENT.
Green Belt
5.5 Green Belts are areas of countryside and open land, which are defined by local planning authorities, for one or more of five main purposes:
 
  • to check the unrestricted sprawl of large built-up areas;
  • to prevent neighbouring towns from merging into one another;
  • to assist in safeguarding the countryside from encroachment;
  • to preserve the setting and special character of historic towns; and,
  • to assist in urban regeneration by encouraging the recycling of derelict or other urban land.
5.6 The Green Belt in Preston, which is mainly confined to the Ribble escarpment and flood plain to the east of the City, is only a small part of a larger area designated in the Lancashire Structure Plan to prevent development between Preston/Walton-le-Dale/Chorley and Blackburn to the east.
5.7 Green Belts constitute a fundamental part of the Structure Plan strategy. By their very nature Green Belts contain areas susceptible to development pressures. These pressures must be resisted and deflected elsewhere through a general presumption against development.
5.8 Government policy on is contained in PPG2: 'Green Belts', which states that the purposes of including land in Green Belts (as set out above) are of paramount importance to their continued protection and should take precedence over the land use objectives. PPG2 defines these objectives:
 
  • to provide opportunities for access to the open countryside for the urban population;
  • to promote the use of land near urban areas for outdoor sport and recreation;
  • to retain and enhance landscapes, near to where people live;
  • to improve damaged and derelict land around towns;
  • to secure nature conservation interests; and,
  • to retain land in agricultural, forestry and related uses.
5.9 Inappropriate development must be avoided. This includes large-scale leisure projects involving major building work and generating significant car traffic requiring extensive parking facilities; football stadia are an example.
5.10 The replacement of existing dwellings need not be inappropriate, providing the new dwelling is not materially larger than the dwelling it replaces.
5.11 The following policy is, for the most part, derived from the Lancashire Structure Plan, with minor amendment to cater for Preston's circumstances.
Policy DC1 Green Belt
Within the Green Belt, as defined on the Proposals Map:
(a) Planning permission will not be given except in very special circumstances for the erection of new buildings other than for the purposes of agriculture, forestry, essential facilities for outdoor sport and recreation, for cemeteries and for other uses which preserve the openness of the green belt and which do not conflict with the purpose of including land in it, or limited extension, alteration or replacement of existing dwellings.
(b) The re-use of existing buildings will be permitted provided that:
  (i) development will not require unnecessary expenditure by public authorities and utilities on the provision of infrastructure;
  (ii) it is in scale and keeping with the features of the landscape character tracts identified in policy DC9, and has regard to the interests of nature conservation, and the need to integrate the development with its surroundings;
  (iii) the environmental impact of any redevelopment will not be greater than that of existing development;
  (iv) the buildings are of permanent and substantial construction and are capable of conversion without complete or major reconstruction;
  (v) there are no adverse implications for the rural economy.
(c) Other forms of development (than those referred to above) will not be permitted unless they maintain openness and do not conflict with the purposes of including land in the green belt.
   
5.12 Hitherto Preston's Green Belt has been defined solely by the Preston Rural Areas Local Plan (PRALP). On preparing the Preston Local Plan, it became apparent that land at the northern part of the Fishwick Golf Course had been excluded from the Green Belt simply because it was situated just outside the PRALP boundary, and within the Preston Eastern Suburbs Local Plan (PESLP). The PESLP does not contain a Green Belt policy. The land in question is contiguous to the Green Belt (as defined by PRALP) and of similar quality and importance. It has therefore been incorporated in to the Green Belt on the Proposals Map.
5.13 The Deposit Plan included within this extended area of Green Belt an area of land off Butterlands, a residential cul-de-sac extending off Glenluce Drive. Following representations from the site's owners the Council reconsidered this site and deleted it from the Green Belt. Planning permission was given for residential development on the southern part of the site, with the northern part being identified as Public Open Space. The Proposals Map now reflects these changes.
   
Open Countryside outside the Green Belt
5.14 PPG7 provides national guidance for the protection of the countryside. There is recognition that the countryside should now be protected in its own right, as a resource both for those who live and work there and for those who visit. (PPG7 paragraph 2.1.4) This concept is expanded in the Lancashire Structure Plan and further defined in this plan.
5.15 The type and amount of development in the open countryside must be strictly controlled. However, it may be acceptable for development to take place where it is required for the purposes of agriculture, forestry, or other appropriate use, or alternatively, when it involves the re-use of existing buildings for employment or housing. Infilling (within the terms of policy DC11) may also be acceptable.
5.16 Policy DC2 sets out the criteria against which the Council will assess proposals for development in open countryside.
Policy DC2 Open Countryside outside the Green Belt
Development in the open countryside, outside the Green Belt, will be permitted where:
(a) it forms a requirement for agriculture, forestry or other uses appropriate to a rural area including uses which help to diversify the rural economy; or,
(b) it comprises infilling between existing buildings in accordance with Policy DC11; or,
(c) it involves the re-use or re-habitation of existing buildings in accordance with Policy DC12.
Development as in (a) (b) or (c) above will be subject to the following provisos:
  (i) it does not involve works to the highway which are incompatible with the rural character of the area; and
  (ii) the development is in accordance with landscape policy DC9 and is compatible with nature conservation; and
  (iii) within the Forest of Bowland AONB, development in the open countryside will be subject to the additional requirement that it will contribute to the conservation of the natural beauty of the area.
   
5.17 It is important that development does not adversely affect either the character of the countryside, (in line with identified landscape types - see Policy DC9) or the amenity of those living nearby. Development to satisfy separate highway criteria may require road improvements which are not in character with that area and these may not be acceptable.
5.18 Special considerations apply to Areas of Outstanding Natural Beauty (AONBs) where development should not only meet the criteria of the policy but should also contribute in a positive way.
   
Development and Agriculture
5.19 Agricultural land is a vital resource for future generations. However, few areas of agricultural use are free from the pressures of development, particularly at the edges of towns. It is national planning policy that the most productive land is retained for agriculture. Land classified as Grades 1 and 2 by the Ministry of Agriculture, Fisheries and Food is the highest quality; Grade 3a land is more widespread and it assumes greater importance to the local agricultural economy in many areas where it constitutes the highest quality land.
5.20 The Council will consult the Ministry of Agriculture, Fisheries and Food about any development which involves, or is likely to lead to, a loss of more than 20 hectares of agricultural land of Grades 1, 2, or 3a. Its views will be a material consideration in determining the Council's decision.
5.21 In many agricultural areas not included in the better categories of land, high productivity is achieved by good husbandry, investment over many years, and by an evolution of farming practice and farm structure which maximises the more limited potential of the land. In the hills of the Bowland area, even though the land is not of the highest quality, particular agricultural practices can have an important influence on the quality of the environment. The loss of such farmland for development should be avoided where alternative locations exist.
5.22 Inevitably some agricultural land will be lost to development. The location and design of any development must be such that agricultural land is not wastefully used and is not broken up by spurs of urban development. There is both an economic and an environmental need to prevent the severance and fragmentation of farm holdings.
5.23 Proposals which may have an impact on sites of ecological and wildlife importance will be assessed against policies DC5 and DC7 below.
Policy DC3 Agricultural Land
Agricultural Land will be protected from development involving permanent loss of, or damage to its agricultural quality to the extent indicated below:
(a) considerable weight will be given to protecting from development the best and most versatile agricultural land i.e. Grades 1, 2, and 3a;
(b) within these grades, where there is a choice between sites of different classifications, development of the higher or highest grade land will not be permitted.
Development of lower grade land (whether or not involving loss or damage to its agricultural quality) will not be permitted where particular agricultural practices contribute to the quality of the environment in some special way.
Where urban development of agricultural land is permitted, steps will be taken by careful consideration of its detailed planning, to minimise any potential conflict with farming operations and to maintain farm efficiency as far as practicable.
   
Agricultural Diversification
   
5.24 Changes affecting the economic viability of existing farms may be compensated by development which is complementary to the main farming enterprise, for example tourism or recreation uses.
5.25 Proposals for diversification will be considered by the Council preferably within the context of a comprehensive farm plan but, as a minimum, applicants will need to explain the links between the intended use and the traditional farm activities.
5.26 Farm shops are a legitimate means of contributing to the rural economy. Proposals for farm shops will be considered against this and other appropriate plan policies. Annex C to PPG7 provides advice on planning issues relating to farm shops and other forms of farm diversification.
Policy DC4 Agricultural Diversification
Proposals for agricultural diversification will be permitted where:
(a) it is of an appropriate scale and character to the local area; and,
(b) the applicant can demonstrate that it will be related to an existing agricultural business.
   
Nature Conservation - Internationally and Nationally Important Sites
5.27 In the countryside surrounding Preston, and in some cases extending into the urban area, there are many areas and sites which have a high value as habitats for plants and animals.
5.28 These areas make up the City's "Critical Environmental Capital", and are natural resources which should be conserved for the benefit of future generations. Some habitats included are irreplaceable and their loss could only be condoned in most exceptional circumstances.
5.29 Nature conservation issues are dealt with in PPG9: 'Nature Conservation' and the Structure Plan. The particular areas to be protected are identified in the following policy.
Policy DC5 Nature Conservation - Internationally and Nationally Important Sites
(a) Development will not be permitted which is likely to destroy or damage the internationally important environment of the Ribble Estuary.
(b) Development will not be permitted which is likely to destroy or damage Red Scar and Tun Brook Woods Site of Special Scientific Interest unless the reasons for development clearly outweigh the site's national importance. In this event, mitigation measures will be required.
   
5.30 The Ribble Estuary is of international importance for the populations of wintering waterfowl it regularly supports; it is an integral part of the Ribble and Alt Estuaries Special Protection Area (SPA) and is also a Ramsar site. In terms of national designations, the estuary is a Site of Special Scientific Interest (SSSI) and large areas are managed as a National Nature Reserve (the Ribble Estuary NNR). Whilst these designated areas lie outside the City, development proposals within the City, especially along Preston's tidal stretch of the Ribble (to Mete House), could have an adverse environmental impact downstream. Any plan or project likely to have a significant effect upon the SPA/Ramsar will be subject to the provisions of the Conservation (Natural Habitats, &c.) Regulations 1994.
5.31 Sites of Special Scientific Interest are notified for their national significance, normally containing important species of flora and fauna, or assemblages thereof. Red Scar and Tun Brook Woods SSSI is Ancient Semi-Natural Woodland and as such any damage or destruction to it represents a loss of Critical Environmental Capital that cannot be compensated for. Development that would destroy or damage the SSSI, either in whole or in part, would not be permitted unless the reasons for the development clearly outweigh the nature conservation value of the site itself and the national policy to safeguard the national network of such sites. In the unlikely event of such development taking place then it is imperative that any damage or destruction to the SSSI is kept to a minimum through sensitive design and appropriate working methods. Such measures will need to be considered in detail by English Nature as the agency responsible for SSSI's, and the Lancashire Wildlife Trust which manages a significant part of the SSSI as a nature reserve. The Council will also seek to mitigate against any damage or destruction of the SSSI through appropriate habitat creation on adjacent land and/or through enhanced management of the remainder of the SSSI. For example, new native woodland could be created following the principles promoted by the Forestry Commission (see Forestry Commission Bulletin 112), non-native species could be removed from remaining areas of existing woodland or improvements could be made to the existing footpath network to enhance managed public access.
5.32 The Council will use planning conditions, or it may enter into a planning obligation, to ensure that appropriate mitigation measures are implemented. These measures should be fairly and reasonably related to the development proposed and should concern the management and enhancement of the SSSI.
   
Protected Species
5.33 European Protected Species are those plants and animals listed in Annex IV to the Habitats Directive and are protected under the Conservation (Natural Habitats, &c.) Regulations 1994. In considering planning applications which may affect European Protected Species, local planning authorities are bound by Regulation 3(4) to have regard to the Habitats Directive when exercising their functions. In order to derogate from the protection afforded to European Protected Species, three tests must be satisfied before DEFRA can issue a licence to permit otherwise prohibited acts:
 
  • that the development is "in the interests of public health and public safety, or for other imperative reasons of overriding public interest, including those of a social or economic nature and beneficial consequences of primary importance for the environment" (Regulation 44(2)(e));
  • that there is "no satisfactory alternative" (Regulation 44(3)(a)); and,
  • that the derogation is "not detrimental to the maintenance of the populations of the species concerned at a favourable conservation status in their natural range" (Regulation 44(3)(b)).
Certain other plant and animal species are protected under the Wildlife and Countryside Act 1981 (as amended) and other legislation.
5.34 The presence of a protected species is a material consideration when a local planning authority is considering a development proposal which, if carried out, could result in harm to the species or its habitat. In these circumstances the Council will consult English Nature before determining the planning application. Where approval of the application is appropriate, the Council will consider attaching planning conditions, or will enter into planning obligations, under which the developer will take steps to secure the protection of the species concerned.
Policy DC6 Protection of Species
The Council will safeguard protected species and their habitats from any adverse effects of development. Any proposal that is permitted on sites supporting such species will make provision for the protection, enhancement and conservation of these species and habitats.
   
Nature Conservation: Locally Important Sites
5.35 Biological Heritage Sites (BHS's) are the most important non-statutory wildlife sites in Lancashire. They have been defined by ecologists at Lancashire County Council, in partnership with the Lancashire Wildlife Trust and English Nature, on the basis of objective biological criteria. There are currently 40 BHS's in Preston. The BHS classification embraces a wide variety of habitats, from Ancient Woodlands to the Lancaster Canal. BHS's form an irreplaceable part of the countryside and deserve recognition and protection through the Local Plan. However, the successful conservation of these sites requires more than protection by the planning system; it also depends in practice upon the co-operation of the owners and occupiers of the land in question. To this end, the BHS Project aims to make contact with the owners and managers of such sites and provide them with information and other assistance. Appendix 3 contains a schedule of BHS's in Preston.
Policy DC7 Nature Conservation: Locally Important Sites
(a) Development will not be permitted which is likely to destroy or damage Biological Heritage Sites and Regionally Important Geological Sites (as shown on the Proposals Map) unless the reasons for development clearly outweigh the need to safeguard the intrinsic nature conservation value of the site or feature.
(b) Development will be permitted on other sites where there are features of habitat or natural history value including mature trees, woodland, established hedgerows and water features, provided that these features are substantially retained. Where retention of such features is not practical, planning permission will be granted where proposals include adequate appropriate replacement features to compensate for those lost.
   
5.36 All of the Preston's Ancient Woodlands are included in the list of Biological Heritage Sites, except for Red Scar and Tun Brook Woods which have been designated a Site of Special Scientific Interest (see Policy DC5). Ancient Woodlands are areas that have been continually wooded since about the year 1600. They are indicated on the Proposals Map to denote a sub-designation of BHS's and are listed separately in Appendix 4.
5.37 The Council will use planning conditions, or enter into a planning obligation, to secure the compensatory provision of replacement nature conservation features. In certain circumstances, the Council may seek to safeguard the intrinsic nature conservation value of a site by means of a management agreement. Such agreements may be secured by the use of planning obligations where proposals involve the use of a site for "noisy" sports.
5.38 Certain plant and animal species are protected under the 1981 Wildlife and Countryside Act and other legislation. The presence of a protected species is a material consideration when a local planning authority is considering a development proposal which, if carried out, could result in harm to the species or its habitat. In these circumstances the Council will consult English Nature before determining the planning application. Where approval of the application is appropriate, the Council will consider attaching planning conditions, or will enter into planning obligations, under which the developer will take steps to secure the protection of the species concerned.
   
Wildlife Corridors
5.39 Wildlife corridors are linear features such as river valleys that connect countryside and urban greenspace and act as links from one wildlife habitat to another. As rare remnants of semi-natural vegetation, they are necessary to ensure the maintenance of the current range of flora and fauna. Wildlife corridors in the urban area often represent the only opportunity that the less well-off and less mobile members of the community have for direct contact with nature.
5.40 Preston's wildlife corridors were identified by the Lancashire Wildlife Trust in a survey carried out in 1991/92. With the exception of the River Ribble and the Lancaster Canal these wildlife corridors do not meet the criteria for inclusion in the list of Biological Heritage Sites. Nevertheless they are very important collectively and warrant an appropriate degree of protection from development. In particular, development proposals that impinge upon a wildlife corridor will be expected to incorporate measures to enhance the degree of linkage afforded by that corridor.
Policy DC8 Wildlife Corridors
Preston City's wildlife corridor network will be protected from unnecessary development which would adversely affect it. New development within or near to wildlife corridors will be expected to incorporate features to facilitate the movement of wildlife, including the creation of new links within the network where appropriate.
   
Landscape Enhancement and Conservation
5.41 The Structure Plan defines landscape character tracts which can be eroded by the cumulative impact of small-scale changes. Four particular tracts are found in Preston and these are illustrated in Plan No. 4. Each has a particular character which is important to safeguard in its own right.
5.42 "Coasts and Estuaries", special features of which are sand dunes, salt marshes, coastal cliffs and grasslands, beaches, and other intertidal habitats. Renewal and enhancement of this landscape is best achieved by the creation of coastal grasslands, management of sand dunes, and small-scale enhancement and habitat creation measures.
5.43 "Amounderness", special features of which are remnant peatlands, wetlands, and ponds. Renewal and enhancement of this landscape is best achieved by woodland and hedgerow management, pond conservation and creation, sympathetic new woodland planting, and the creation of wetland and other semi-natural habitats, and habitat links.
5.44 "Bowland Fringes", special features of which are ancient woodlands and species-rich grasslands. Renewal and enhancement of the landscape is best achieved by hedgerow and hedgerow tree planting and management, and woodland and grassland management.
5.45 "Rural Valleys", special features of which are rivers, ancient woodlands, and species-rich grasslands. Renewal and enhancement of the landscape is best achieved by woodland, hedgerow, and hedgerow tree management.
Policy DC9 Landscape Enhancement and Conservation
(a) In rural areas the distinctive landscape and habitat features of the landscape character tracts identified in the Lancashire Structure Plan will be conserved, renewed, and enhanced by tree planting (where appropriate), habitat management and creation, derelict land reclamation, environmental improvement and river corridor conservation, and by the incorporation of such measures into development. Priority will be given to conserving and enhancing the Forest of Bowland Area of Outstanding Natural Beauty.
(b) In urban and urban fringe locations landscape will be enhanced by:
  (i) the re-use of derelict and degraded land;
  (ii) the deployment of greenspace networks and other open spaces;
  (iii) the protection and creation of areas of woodland;
  (iv) environmental improvements carried out as part of redevelopment and refurbishment schemes or in conjunction with traffic management measures.
   
5.46 The implementation of this policy will be achieved through a wide spectrum of measures. These include countryside management schemes and other joint working and initiatives with statutory and voluntary agencies, taking into account policies and plans such as the Environment Agency's Local Environment Agency Plans for the River Ribble; the County Council's indicative Forestry Strategy; and the City Council's Community Woodland Strategy.
5.47 The policy will also be implemented by the incorporation of appropriate measures within new development through the development control system. The Council may attach conditions to planning permissions, or enter into planning obligations with developers, to enable development to proceed. The measures required will depend upon the nature of the proposed development and the particular character of the landscape but may include the use of appropriate materials and hard and soft landscaping.
   
  Plan No: 3 - Landscape Character Tracts - Policy DC9
   
Rural Villages
5.48 Limited development within the following well-established villages will promote rural enterprise and support the rural economy:
 
  • Broughton;
  • Grimsargh;
  • Barton;
  • Woodplumpton;
  • Lea Town.
5.49 These villages are identifiable settlements which have well-established residential areas and provide a range of services. As such they are identifiable settlements which satisfy the criteria set out in Policy 10 (Development in Rural Settlements outside Green Belt) of the Lancashire Structure Plan.
5.50 Settlement Development Boundaries have been defined on the Proposals Map for each of these villages. The main aim of Settlement Development Boundaries is to keep the built up areas of villages in a compact form and character so that the surrounding open countryside is protected from unwarranted and unsuitable development.
5.51 Small site development is acceptable in principle within the Settlement Development Boundaries. This may take the form of infill development (i.e. the infilling of small gaps within small groups of houses), or the development of larger windfall sites. The re-use or rehabilitation of existing buildings is also permissible. Such categories of development will not affect the form and character of the settlement, and may bring economic and environmental benefits. Settlement Development Boundaries have been defined to ensure that any new development consolidates the settlements and does not result in "ribbon" development.
5.52 Settlement Development Boundaries include within them:
 
  • all buildings that are physically linked to the main settlement;
  • all residential curtilages except where the character and appearance is such that the garden area relates to the open character of the countryside rather than the built up area of the settlement;
  • all undeveloped areas where there are extant planning permissions for development or specific allocations which consolidate built up character and settlement form;
  • other open areas, such as recreational greenspace or public open space, that is enclosed within the compact form and character of the settlement.
5.53 The process of defining Settlement Development Boundaries began with the village boundaries established in the Preston Rural Areas Local Plan (adopted 1990). In comparison with the 1990 boundaries, the Settlement Development Boundaries differ in some minor respects. In some cases the boundary of a village has been extended to include new developments or extended residential curtilages in accordance with the criteria listed above. In other instances the boundaries have been pulled back where the above criteria indicate that, in order to maintain a compact settlement form, certain areas should be left outside the settlement.
5.54 The predominant land use in the defined settlements is residential. Consequently the majority of the area within each Settlement Development Boundary is defined as "existing primarily residential area" on the Proposals Map. This means that proposals for development within these areas will be subject to certain housing policies, particularly H1 (Housing Development outside Allocated Areas), H5 (Development Proposals in Existing Residential Areas), and H11 (New Business and Employment Uses in Residential Areas). The supporting text to Policy H5 explains how existing primarily residential areas are defined. Significant areas of greenspace that serve the settlement are also included within the Settlement Development Boundary.
5.55 Whilst the objective of this policy is to retain the compact form and character of the villages concerned, it is recognised that some development may, in exceptional circumstances, be acceptable outside the Settlement Development Boundary. These exceptions relate to the necessity of meeting a recognised local employment, community, or housing need arising in the village but where the development required can not be accommodated satisfactorily within the Settlement Development Boundary. Such proposals would require detailed justification and careful site selection to minimise their impact on the settlement form and on the open countryside.
Policy DC10 Rural Villages
Development will be permitted in the rural villages of Broughton, Grimsargh, Barton, Woodplumpton, and Lea Town when it:
(a) is infill and/or the re-use of buildings within the Settlement Development Boundary of the village as defined on the Proposals Map; and,
(b) is consistent with the requirements of Policy H1 for housing proposals; or,
(c) adjoins but is outside the Settlement Development Boundary, in special circumstances only to meet a specifically identified local employment, local community or local housing need and which could not be sited within the Settlement Development Boundary.
In all the above circumstances, the existing character and appearance of the village should not be harmed, nor the amenities of nearby residents.
   
Infilling In Rural Building Groups
5.56 The filling of small gaps in building groups is considered to be an exception to the general policy of restricting new development outside villages. It has little effect on rural character where there is already an existing group or row of buildings and small gaps in such locations are usually of little agricultural value. The development should be of similar type to existing property such that it complements and completes the existing group. For this reason it may in some circumstances be appropriate to develop a site for a number of small buildings rather than one large one, if the neighbouring properties are not of that character.
Policy DC11 Infilling in Rural Building Groups
Infill development in an existing group or row of buildings will be permitted where all the following criteria are met:
(a) the existing buildings form a clearly identifiable group or row, not a vague or sporadic scattering of buildings: there should be at least five buildings in the group;
(b) the proposed plot lies within the group or row, with buildings on either side and its development completes but does not extend the group or row;
(c) the form of development would complement the character and relationship of the existing buildings within the group.
   
Conversion of Rural Buildings
5.57 For the countryside to remain a working environment it is vital that the rural economy be allowed to diversify. As the countryside must also be protected for its own sake, the sensitive conversion of existing buildings to employment and housing uses is a way of providing both local employment and housing opportunities and protecting the countryside from new development.
5.58 Employment uses (including tourism) are to be encouraged because residential conversions make little lasting contributions to the rural economy. Residential conversions can also have a more harmful effect on the character of the countryside through the creation of a residential curtilage. Residential conversions can often have a more detrimental effect on the fabric and character of historic farm buildings because of the need to create new elevational openings. Works to rural buildings can often lead to the discovery of important historic evidence. It sometimes may be necessary to allow an archaeologist on site to record any findings and perhaps undertake further research (see Policy C9).
Policy DC12 Conversion of Rural Buildings
The conversion of existing buildings in the open countryside and rural villages to either commercial or housing use, will be permitted subject to the design criteria in Policy D19 and where there are no adverse implications for the rural economy. All the following criteria should be satisfied:
(a) the building is structurally sound and capable of conversion to the proposed use without major extensions or alterations;
(b) if the external appearance of the building and/or any ancillary buildings detracts from the visual amenity of the area, improvements are proposed;
(c) the proposals cause no demonstrable harm to the amenity of adjoining residents or to neighbouring uses or the character of the countryside;
(d) in the case of conversion to business and industrial use, proposals must demonstrate that related goods storage, vehicle parking and turning areas can be accommodated satisfactorily on site;
(e) in the case of a farm building which was erected by virtue of permitted development rights* that there is proof that it has genuinely been used for the purpose for which it was constructed.
To satisfy criterion (a) the applicant will be required to provide proof that the building is sound (in the form of a professional structural survey) and that no more than 30% of the surface area of external walls will require rebuilding.
In the case of modern agricultural buildings not of traditional design and materials there will be a presumption against conversion to residential use. Conversion to commercial uses will be judged against the criteria set out above.
* Schedule 2, Part 6, Town and Country Planning (General Permitted Development) Order 1995.
   
5.59 This policy must be read in conjunction with Policy D19, which lists a number of criteria which the Council will take into account in determining planning applications for the conversion of rural buildings. Particular attention is drawn to the importance of barns and other rural buildings as habitats for barn owls and bats, which are protected species. Conversions must, therefore, be sympathetic to the needs of wildlife. Further advice is provided in the Council's supplementary planning guidance.
5.60 Reference in criterion (e) to the genuine use of buildings for agricultural purposes will deter the erection of buildings (which do not require planning permission) for which there is little or no agricultural justification, and which are subsequently proposed for conversion.
   
Dwellings For Essential Rural Workers
5.61 The normal restrictions on dwelling provision outside villages may be overcome if an essential need can be justified in connection with an appropriate and existing employment facility requiring constant supervision; these cases are usually in connection with agricultural concerns.
Policy DC13 New Rural Workers Dwellings
The erection of new dwellings in rural areas (outside villages and other than infilling) will be permitted only where it can be demonstrated that there is an essential need for worker(s) to live on the site in the interests of agriculture, forestry or another use appropriate to a rural area. Proposals for such dwellings will be considered taking the following matters into account:
(a) the functional requirements for the enterprise's worker(s) to live nearby. Where the need has arisen due to fragmentation of the ownership or occupation of an agricultural holding, the applicant will need to demonstrate that the resulting agricultural unit created will have a reasonable chance of establishment;
(b) the labour requirements of the enterprise and the number of workers needed to live on the premises;
(c) the availability and suitability of existing accommodation in the local area. Consent will not be granted where other residential buildings, formerly in the same ownership or occupation, have recently been disposed of;
(d) where the above functional tests are not conclusive, or where an increase in scale or a completely new enterprise is proposed, a sound financial basis for the enterprise must be demonstrated;
(e) the siting and scale of the dwelling which should be closely related to existing buildings on the holding or should minimise any effect on the landscape. Dwellings should be of a size commensurate with the enterprise's established functional requirements;
(f) the suitability of access and availability of drainage and other services.
In cases where the above functional and/or financial tests are not conclusive the Council may grant permission for a caravan or other temporary accommodation to allow time for the essential need for workers to live on site to be demonstrated, or for the viability of the enterprise to be proven.
The Council will attach conditions to any permission granted to control the occupancy of the new dwelling along with that of any existing dwelling.
   
5.62 If a new dwelling is shown to be essential it should be located close to existing buildings to minimise the effect on the landscape. If this is not possible because of the layout of the holding, or access or service constraints, the dwelling may be located away from existing buildings on the holding, but should be screened as far as possible by landscape features or trees to reduce the visual impact on the area.
5.63 Where evidence supporting an application for an agricultural or forestry dwelling is inconclusive, the Council will consider granting temporary permission for the provision of a caravan to allow time for the need to be clearly demonstrated. This will normally be given for 2 or 3 years, and will not be renewed. Temporary permissions will not be granted in locations where a permanent dwelling would not be acceptable.
5.64 Applications for the removal of conditions, attached to permissions for rural workers' dwellings, must show that there has been a genuine change in circumstances and that there is no other demand for such dwellings in the locality, in order to avoid pressure for replacement dwellings.
Policy DC14 Existing Rural Workers' Dwellings
Where dwellings have been permitted subject to condition(s) restricting occupancy, such conditions will only be removed where it can be demonstrated by the applicant that:
  (a) the essential need which justified the original grant of planning permission no longer applies; and,
  (b) the dwelling has been occupied for at least five years in accordance with the terms of the original planning permission, unless exceptional circumstances can otherwise be demonstrated; and,
  (c) the dwelling has been offered for sale on the open market for a period of at least 12 months at a realistic price, taking into account the existence of the condition, and that no reasonable offers have been refused.
   
5.65 The market value of such dwellings is lower than that of dwellings unencumbered by a condition and this should be reflected in the sale price.
5.66 The confidentiality of any offers made will be respected and, although not part of the planning application, evidence will need to be produced when available.
   
Protection of Rural Shops and Businesses
5.67 Local shops and businesses contribute significantly to the social and economic health of the rural community. The retention of such uses can go some way towards reducing the number of trips generated for the purchase of convenience goods. Central Government gives support in both PPG's 6 and 7 for the retention of these wherever possible.
Policy DC15 Protection of Rural Shops and Businesses
The change to other use of non-agricultural rural buildings used, or last used, as shops or businesses will be permitted where it can be demonstrated that:
(a) the use is not viable and no longer primarily serves the needs of the community in which it is located; and,
(b) applications are supported by evidence that the property has been offered for sale on the open market for a period of at least 12 months at a realistic price and that no reasonable offers have been refused.
   
Surface and Ground Water Supplies
5.68 Great care is needed to ensure that development does not cause the pollution of water courses. This could come about as a result of an industrial activity which is inadequately controlled, or it may be that there is insufficient infrastructure or capacity on the sewage network to deal with further development.
5.69 Groundwater is particularly vulnerable to the effects of pollution. Groundwater forms part of the natural water cycle which is present within underground strata (aquifers). There are considerable groundwater resources in the Preston area, and they are an important source of public water supply. Groundwater also naturally feeds surface water though springs and the base flows to rivers. It is very important to protect these resources from the adverse effects of development.
Policy DC16 Surface Water and Ground Water Supplies
Development which would have an unacceptable effect on the quality or yield of groundwater or surface or coastal water resources will not be permitted.
   
5.70 The Environment Agency has powers and duties under the Water Resources Act 1991 concerning the protection of groundwater and surface water resources. They are a statutory consultee and the Council will consult closely with them on any proposals which could potentially result in the pollution of water resources.
