ENVIRONMENTAL PROTECTION AND ENHANCEMENT

 

Introduction

The borough of Warrington contains significant areas of open countryside, much of which lies within the broad extent of the green belt as indicated in the Cheshire 2001 Structure Plan. The UDP will establish, for the first time, detailed green belt boundaries within the borough. It also affords protection to other areas of countryside of notable landscape value and Sites of Importance for Nature Conservation (SINCs). It reflects European legislation to protect endangered species and also recognises the need to protect features such as hedgerows, ponds and watercourses, which are important for their wildlife and/or recreational value.

Other policies within this chapter seek to protect valuable areas of open space within the borough’s urban areas, such as playing fields and other areas used for informal recreation. Policies within this chapter of the UDP aim to protect and where possible enhance the natural environment, whilst facilitating new development where appropriate.

National Planning Policy Guidance

Green belts have been an essential element of planning policy for over four decades. Government guidance on green belts is contained in PPG2 which, inter alia, sets out:

  • the general intentions of green belt policy and purposes of including land in green belts;
  • advice on defining boundaries and on safeguarding land for longer-term development needs; and
  • a presumption against inappropriate development within green belts.

Planning policies for the countryside are set out in PPS7 ‘Sustainable Development in Rural Areas’, which emphasises the need to sustain economic activity in rural areas whilst protecting the countryside. It acknowledges that whilst stricter controls are necessary in open countryside and in areas designated for their landscape, wildlife or historic value, rural areas can, with sensitive planning policies, accommodate many forms of new development. Whilst the borough has tracts of attractive, open countryside, it is not typified by a rural economy (the 1991 Census shows that only 0.76% of the workforce are employed in agriculture). PPS7 advises that development plan policies should reflect the need to promote sustainable development and:

  • encourage rural enterprise and diversify into new agricultural opportunities;
  • protect landscape, wildlife and historic features;
  • have regard to the quality and versatility of land for use in forestry and other rural enterprises;
  • protect other non-renewable resources;
  • strengthen rural communities by encouraging inclusive and accessible new employment, facilitating an adequate supply of affordable and market housing and underpinning services and community facilities;
  • achieve good quality development which respects the diversity and character of the countryside; and
  • secure safe development by taking account, where appropriate, of the stability of the land.

It also requires development plans to safeguard the best and most versatile agricultural land (see policy REP2 in part 1 of the UDP).

PPG9 'Nature Conservation' sets out the Government’s policies relating to the natural environment and the role of the planning system in protecting valued habitats from development, and in securing enhancement of the natural environment through development control where appropriate.

PPG17 'Planning for Open Space, Sport and Recreation' describes the planning system’s role in assessing sporting and recreational needs and in safeguarding open spaces with recreational or amenity value. It requires local planning authorities to carry out open space assessments. The guidance outlines the minimum content of these assessments and states that they must have a qualitative component. National standards are to be replaced by local standards that must include quality, quantity and accessibility components. Open space must be shown to be surplus in all possible uses rather than just its existing use. Local planning authorities are expected to require commercial and industrial developments to include open spaces, not just landscaping, and to consider visitors' needs. It encourages local planning authorities to take account of the community’s need for recreational space, to have regard to current levels of provision and to protect and improve open space in areas of deficiency. It also says that part 2 of the UDP should include specific policies on public access to open space which has recreational value.

Regional Spatial Strategy

In addition to the policies summarised in the preamble to the UDP’s Housing chapter, RPG (now RSS) contains a number of policies which reflect the importance of actively managing environmental resources. These include:-

  • ER1 relating to management of the region’s natural, built and historic environment;
  • ER2 relating to landscape character;
  • ER3 relating to built heritage;
  • ER5 relating to biodiversity and nature conservation; and
  • ER6 relating to woodlands, encouraging at least a 15% increase in the region’s tree cover by 2020.

As part of the drive to secure an urban renaissance within the North West’s towns and cities, RPG (now RSS) also contains policy UR10, under which local authorities and other agencies should identify the urban areas in need of more green space, and develop appropriate strategies for the design, management, maintenance and enhancement of the public realm and urban green space.

Local Strategy/Part 1 UDP Policies

GRN1 The Green Belt

Green belts are a long-established element of planning policy, serving to check the unrestricted sprawl of large built-up areas; prevent neighbouring towns from merging into one another; assist in safeguarding the countryside from encroachment; preserve the setting and special character of historic towns; and to assist in urban regeneration by encouraging the recycling of derelict and other urban land.

This UDP seeks to establish, for the first time, detailed green belt boundaries within the borough. The only exceptions are a few small areas on the borough’s boundary, which were designated as green belt in the Greater Manchester and Merseyside Green Belt Subject Plans prior to their being transferred into Warrington following Local Government boundary reviews, together with parts of the areas covered by ‘part-area’ local plans adopted by the Council in the 1980s.

The essential feature of the green belt is its permanence. In accordance with PPG2, the Council has drawn up green belt boundaries capable of enduring well beyond the end of the plan period (2016). As part of this exercise it has also identified potential sources of land supply which could accommodate development that, subject to future reviews of strategic guidance, will be required beyond 2016 and within the life-span of the green belt boundaries established in this UDP.

The UDP strategy is concerned with the overall balance between the needs of development and the interests of conservation. The plan is also concerned with ensuring that, whenever and wherever it is necessary to allocate land for development, development contributes towards the principles of sustainable development through its general location, its juxtaposition with neighbouring uses and transport routes, and the mix of uses it contains. Choices about future development must respect these principles and be restricted to areas that fall within the agreed environmentally acceptable ‘limits to growth’ in the borough.

A vital measure in securing adherence to these principles through planning policy, is the establishment of green belt boundaries which are capable of remaining unaltered for as far as can be seen ahead. In that regard, the UDP takes its lead from RPG (now RSS) policy SD5 which states that, following establishment of the green belt boundaries in Warrington for the first time in this UDP, there will be no need to undertake a further study of strategic or detailed boundaries before 2021. It is acknowledged that some years would be required for such a review to run its course and for a ‘lead-time’ for preparation of land and granting of planning permissions for any required development to take place on land released from the green belt (if that were to be the outcome of the review). It is thus reasonable to conclude that the green belt boundaries now defined should be capable of accommodating development requirements until about 2026, i.e. 10 years beyond the end of the plan period.

The green belt boundaries, as described in policy GRN1 and shown on the proposals map, thus define the minimum extent of the green belt required to ensure that the fundamental purposes of the North Cheshire Green Belt are secured within the borough, for as far as can be seen ahead at the time of preparation of the UDP.

In delineating the green belt boundaries, the Council is satisfied that the amount and distribution of land potentially available for development, both within the plan period to 2016 and throughout the intended life of the green belt thereafter, is capable of accommodating any reasonably foreseeable future development requirements.

Whilst it is accepted that there is uncertainty as to the strategic planning framework that will guide Warrington’s development after 2016, the Council accords great weight to the emphasis that RPG (now RSS) places on the overriding priority for development and investment in the region to be directed to the regeneration of the cores of the conurbations, and on the challenge it sets for local authorities to co-operate to ensure that the sequential approach to allocating and releasing land for development (including bringing unused buildings back into use) is reflected in co-ordinated decision-making across authorities’ boundaries. The need to positively resist greenfield releases throughout the region to support that strategy is emphasised strongly.

The quest for an urban renaissance, which is at the heart of RPG (now RSS), needs to be supported by a long-term strategic approach, with the implication that the protection of greenfield sites from development, except where demonstrably necessary to sustain RPG’s (now RSS) Core Development Principles and Spatial Development Strategy, should continue for the foreseeable future, i.e. beyond 2016. RPG (now RSS) does not prescribe or presume that housing development rates applying to 2016 for individual authorities’ areas should continue beyond 2016. It is considered proper to assert that any future review and possible adjustment of those rates of development (including reviews taking place in the period up to 2016) should be driven by the need to keep the region’s urban renaissance strategy on course.

The protection of the green belt, in particular, is referred to in RPG (now RSS) policy SD4 as an essential tool in maintaining urban form, enhancing urban living and ensuring a visually attractive and accessible setting around all settlements; all being essential components of the strategy underpinning the desired urban renaissance.

The Council placed a high degree of reliance upon RPG during the preparation of the revised deposit UDP and, in keeping with its support for the key components of the regional planning strategy, considered it necessary and appropriate to delineate green belt boundaries which will place reasonable limitations on opportunities for outward expansion of Warrington on to greenfield sites for the foreseeable future. To that end, the Council has felt justified in including in the green belt all of those sites to which the First Deposit Draft UDP policy GRN2 'Safeguarded Land' had been designed to apply. Each of those sites fulfils at least one of the purposes of including land in the green belt, as established in PPG2, taking account, in particular, of the raised significance of the green belt’s function of supporting urban regeneration as emphasised in RPG (now RSS). Evidence of a potentially more than adequate supply of housing and employment land to 2016 has been set out in the justification for policies HOU1 and EMP1 and in the Council’s evidence to the Inquiry.

It is also important to show that there will be continuing sources of supply beyond 2016 and within the intended life-span of the green belt boundaries as now defined. In that regard, the up-to-date assessments of housing and employment land supply, together with forecasts of the reasonably-expected rate of take-up of land and of prospects for additional land coming forward through a pro-active urban regeneration strategy, point to the potential availability of a continuing post-2016 supply of land from the following sources:

English Partnerships’ land-holdings in South Warrington, covered by approvals under section 7(i) of the New Towns Act, now to be subject to a phasing policy under policy HOU1 (with a capacity for 1,237 houses, subject to review of densities as part of any proposals for their release if and when required).

Further ‘windfalls’ for housing, employment or mixed uses, including those sourced from Potential Urban Regeneration Areas identified in policy EMP8, with the expectation that the ‘lead-time’ required for infrastructure provision will leave a significant but currently unquantifiable proportion of land within those areas available for development after 2016.

Approximately 60 hectares of the Omega Regional Investment Site, given that the masterplan envisaged a development period of approximately 25 years for the full site. In this regard, whilst it is acknowledged that the Regional Investment Site will provide employment opportunities for residents from a wider area than Warrington, a substantial proportion of employees on the site will be residents of the borough.

Land within committed sites for housing which may ‘slip’ to beyond 2016, without creating a shortfall in supply in relation to requirements in the period up to 2016.

Increased capacity for housing, arising from reviews of densities on identified housing sites in support of guidance contained in PPG3.

A proportion of the sites contributing towards the employment land supply referred to in policy EMP1, which it is expected will remain available for the post-2016 period, on the basis that the policy allows for choices to be made from within that supply to meet requirements to 2016. It is presently forecast that between 30-50 hectares will be available from this source after 2016.

Greenfield sites which may be declared surplus to requirements within the framework of guidance in PPG17 'Planning for Open Space, Sport and Recreation', and which would be released for development only in accordance with the sequential approach to ‘Plan, Monitor and Manage’ the release of land for housing.

Land from within some of those identified and potential sources of supply is likely to be developed before 2016 where this is unavoidable or imprudent in terms of the contribution that swift release of previously-developed land can make to urban regeneration in Warrington. The potential effects of this, in exacerbating what is already a potential ‘over-provision’ of land to 2016 in relation to RPG (now RSS) requirements, may be seen to have diverted development and investment away from the region’s priority regeneration areas. Should monitoring at regional and sub-regional levels show that to be the case, it would properly raise the issue as to whether ‘corrective’ action should be taken in reviews of RPG (now RSS), by further reducing the rate of development in Warrington to both reinforce the region’s urban renaissance strategy and help ensure the long-term protection of the green belt within the borough.

GRN2 Environmental Protection

This policy sets out the Council’s overall strategy to protect important elements of the borough’s natural and built environment. It seeks to protect the open countryside by directing new development towards existing built-up areas. This approach is consistent with the aims of promoting urban regeneration and sustainability by reducing the need to travel overall and increasing opportunities to travel using public transport.

Within the built-up area, the Council will safeguard valuable open spaces and important features of Warrington’s built heritage. Outside the built-up areas, its aim is to maintain the attractiveness of the countryside by safeguarding and, where possible, enhancing woodland cover, biodiversity and by protecting wildlife and their habitats.

All of these considerations are the subject of more detailed and specific policies in part 2 of the UDP.

GRN3 DEVELOPMENT PROPOSALS IN THE COUNTRYSIDE

Development proposals in the countryside which are not precluded by policies for the green belt will be approved provided that:

  1. the detailed siting of the development is compatible with the character of the surrounding area and is not intrusive in the landscape;

  2. the interests of nature conservation are not compromised

  3. the design of the development relates satisfactorily to its rural setting, in immediate impact, or from distant views, and respects local landscape character;

  4. if significant numbers are likely to be attracted to it, the development provides for access by public transport, cycling and walking to minimise new trips by car and not materially worsen traffic conditions or affect road safety;

  5. car, motorcycle, and cycle parking is provided in accordance with the Council’s parking policy and standards;

  6. unintrusive provision can be made for any associated servicing and parking facilities or plant, equipment and storage;

  7. the development contributes to rural enterprise and farm diversification and has no detrimental impact on agricultural interests or the rural economy;

  8. the proposal incorporates appropriate landscaping and wildlife habitat creation, including tree and woodland planting where appropriate; and

  9. there is no disruption to public footpaths.

Policy Derivation:

PPG1, PPG2, PPS7, PPG12

Reason and Explanation:

This policy is aimed at the rural areas of the borough which are all designated as green belt and policy GRN1 provides that appropriate development may be allowed in these areas. This policy builds upon that general guidance by setting out the criteria against which acceptable forms of development will be assessed in order to maintain the character and appearance of the countryside. Tree planting should utilise locally native species where appropriate.

In addressing landscape character for the purposes of paragraph 3 above, the Council will rely upon its landscape character assessment of the Borough, which will take account of historic character, and will have the status of Supplementary Planning Guidance. At the time of adoption of this Plan that assessment had not been completed and, until it is, the weight to be placed upon it will be limited accordingly.

Area of Coverage:

Within Warrington, the countryside is taken to mean the rural areas lying outside the built-up areas of the town, inset villages and Green Belt villages as defined on the Proposals Map.

Other Related Policies:

GRN1, GRN2, GRN24, LUT1, LUT21, REP1, REP2,

GRN4 INSET VILLAGES

The following villages are inset into the green belt:

The following development will be allowed within inset villages:

  1. housing development and redevelopment of an appropriate scale, character and design, provided the loss of a site previously providing employment is not detrimental to the rural economy or the development of sustainable communities;

  2. conversions of existing buildings to housing, provided their loss is not detrimental to the rural economy through the loss of viable premises for business or commerce;

  3. new employment or mixed-use development of an appropriate scale and type;

  4. development providing local services and facilities of an appropriate scale and type.

Policy Derivation:

PPG2

Reason and Explanation:

1. Villages are inset into the green belt where development is to be allowed within the existing built-up area during the plan period. The following criteria have been used to select inset villages:-

  • They are suitable for accommodating small groups of houses, or
  • There are existing planning permissions for new development: and
  • They already possess local services, including shops and a school.

2. 2. All proposals for housing development will also need to address the requirements of policies HOU2 and HOU3.

3. In the case of Glazebury, further explanation is necessary as the amendment to the village inset boundary involves a change to an adopted green belt. The administrative boundary of the borough was revised with effect from 1st April 1994 and land north of Glazebury which formerly lay in Wigan Metropolitan Borough was transferred to Warrington Borough. The previously identified village boundary coincided with the old borough boundary and thereby excluded land and buildings to the north, which also form part of the settlement. This area, formerly within Wigan is part of the adopted Greater Manchester Green Belt.

4. However, in terms of land use, built form, general appearance and character, the northern most section is indistinguishable from the rest, and it would be wholly illogical for two parts of the same settlement to be subject to entirely different policy regimes within the UDP. In the circumstances, the inclusion of the northern most section of the settlement within the village inset is the correct approach and the reasons for this change, as endorsed by the Warrington Borough Draft Local Plan Inspector, represent exceptional circumstances which justify the alteration to the adopted green belt.

5. The Council has worked with local communities to prepare Village Design Statements, to promote development that is in keeping with individual villages. These Design Statements have been successfully adopted as Supplementary Planning Guidance.

6. Grappenhall Heys was originally planned as an integral element of the New Town Outline Plan’s proposals for expansion onto previously undeveloped land in south Warrington, contiguous with the established, mainly residential suburbs. In 1989, the (then) Secretary of State granted approval under section 7(1) of the New Towns Act for the development of Grappenhall Heys, in physical isolation from the existing built-up area, and from other areas for which approvals were granted concurrently.

7. A substantial proportion of Grappenhall Heys has either now been developed or is committed to be developed in accordance with subsequent detailed approvals given under section 7(2) of the same act. The balance of the area with extant section 7(1) approval remains committed to development. The remaining open land between the approved 7(1) area and the existing built-up area of Warrington is proposed as green belt.

8. The designation of Grappenhall Heys as an inset village is an appropriate response to the circumstance that has arisen, and will provide a suitable policy framework for the control of development. The defined settlement boundary of Grappenhall Heys is drawn tightly around those areas already developed or committed through section 7(2) approvals and therefore excludes areas with 7(1) approval only. These areas are unlikely to be developed during the plan period as explained and provided for in policy HOU1, in accordance with the sequential test to be applied to greenfield development under PPG3 and the plan, monitor and manage approach to the control of housing development.

Area of Coverage:

Inset villages, as defined on the Proposals Map.

Other Related Policies:

HOU2, HOU3, HOU4, HOU6, HOU7, HOU8, HOU9, HOU10, EMP6

GRN5 GREEN BELT VILLAGES

The boundaries of the following green belt villages are shown on the Proposals Map:

Within these boundaries:

  1. the Council will permit limited infill development of an appropriate scale, design and character, provided that the site constitutes a small break within development, and unless the break contributes to the character of the village or has more affinity with the openness of the green belt than the built form of the village;

  2. proposals for the change of use or conversion of buildings will be subject to policy GRN6;

  3. all other proposals will be subject to policy GRN1.

Policy Derivation:

PPG2

Reason and Explanation:

This policy identifies villages ‘washed over’ by the green belt, which do not satisfy the criteria for inset villages, but are nonetheless established settlements supporting more limited local services and facilities. The development and redevelopment opportunities specified in this policy are of a scale which will not adversely affect the character of the villages nor undermine the purposes of the green belt.

All proposals for housing development will also need to address the requirements of Policies HOU2 and HOU3.

Area of Coverage:

Green belt villages, as defined on the Proposals Map.

Other Related Policies:

HOU2, HOU3, HOU4, HOU6, HOU7, HOU8, HOU9, HOU10, EMP6, GRN6

GRN6 THE RE-USE OF BUILDINGS IN THE GREEN BELT

The re-use of buildings in the green belt will be permitted provided that:

  1. the proposed use does not have a materially greater impact than the present use on the openness of the green belt, the character of the countryside, or visual amenity;

  2. no detriment is caused to the openness of the green belt or the character of the countryside through any associated uses of land surrounding the building;

  3. the buildings are of permanent and substantial construction, and are capable of conversion without major or complete reconstruction;

  4. the form, bulk, and general design of the buildings are in keeping with their surroundings and any associated extensions or alterations respect their character and style, or achieve an improvement to the external appearance of the buildings;

  5. the proposed use does not cause detriment to the amenity of neighbours;

  6. the development will not materially worsen traffic conditions or adversely affect road safety;

  7. the proposal takes account of the interests of nature conservation, particularly where buildings may be used by bats, barn owls, nesting birds or other protected species; and

  8. the proposal does not adversely affect the rural economy through the loss of viable premises suitable for local commerce or industry.

Supplementary Planning Guidance:

Design guidelines for conversion or re-use of buildings in rural areas

Policy Derivation:

PPG2, PPS7

Reason and Explanation:

1. With suitable safeguards, the re-use of buildings should not prejudice the openness of the green belt, since the buildings are already there. The government is keen to encourage re-use as this may prevent vacant buildings becoming derelict, will ensure the careful stewardship of resources, may contribute to the rural economy, and positively contribute to green belt land use objectives.

2. Nevertheless, it is appropriate to exercise careful control to prevent harm to the openness of the green belt and the character of the countryside.

3. In applying clause 2, ‘associated uses of land surrounding the building’ include external storage, extensive hardstanding, car parking and garaging, boundary walling and fencing.

4. The Council will require the submission of a full structural survey where it has reasonable cause to consider that the building cannot be re-used without major reconstruction.

5. If the proposal relates to a building which, in the opinion of the Council, has a significant adverse effect on the landscape in terms of visual amenity, conditions may be imposed on the permission to secure an improvement to its external appearance in connection with any proposed structural changes.

6. Where there is a likelihood that the building may be used by bats, barn owls or other protected species, an investigation will be carried out and if their presence is confirmed, controls will be imposed to ensure damage to habitats is minimised.

7. The Council will examine applications for changes to residential use with particular care. New housing in the open countryside is subject to strict control and this policy applies similar principles to proposals for the conversion of existing rural buildings to dwellings. In particular the creation of a residential curtilage around a newly converted building can sometimes have a harmful effect on the character of the countryside.

8. Additional controls will apply if the building concerned is of Architectural or Historic Interest (See Built Heritage policies).

Area of Coverage:

The green belt as defined on the Proposals Map, including the green belt villages listed in policy GRN5.

Other Related Policies:

GRN1, GRN3, GRN19

GRN7 AGRICULTURAL / FORESTRY DWELLINGS

In the green belt new dwellings for workers engaged in agriculture or forestry will only be permitted where it is essential to the proper functioning of the enterprise to have one or more workers living nearby. Applicants will be required to demonstrate to the Council that such a requirement exists.

Policy Derivation:

PPG2, PPS7

Reason and Explanation:

1. Current national guidance advises that one of the few circumstances in which isolated residential development in the countryside may be justified is when accommodation is required to enable farm or forestry workers to live at or in the immediate vicinity of their place of work. Where a new dwelling is justified, to minimise its impact on the landscape sites within the farm complex should be explored first followed by sites that are close to the complex or to an existing dwelling. Only in exceptional circumstances should other sites be considered.

2. In assessing applications for new dwellings, the Council will apply a ‘functional test’ to establish whether such a requirement exists, e.g. where workers are needed to be on hand day and night:

  • in case animals or agricultural processes require essential care at short notice
  • to deal quickly with emergencies that could otherwise cause serious loss of crops or products.

3. The protection of livestock from theft or injury by intruders may contribute to need on animal welfare grounds, although it will not by itself justify a new dwelling. Requirements arising from food processing, as opposed to agriculture, cannot be used to justify an agricultural dwelling, nor can agricultural needs justify the provision of new retirement homes for farmers.

4. In some cases the Council may also require financial evidence in support of applications for new dwellings where:

the functional test is inconclusive; or

the application relates to the intention to set up a completely new business or a major change in the nature or scale of an existing business.

5. In these circumstances the Council will need to be satisfied that the proposed development is likely to be implemented and will therefore require information regarding investment projections and sources of finance.

Area of Coverage:

The green belt as defined on the Proposals Map.

GRN1, GRN3, GRN5

GRN8 MAJOR DEVELOPED SITES IN THE GREEN BELT

1. The following are identified as major developed sites in the green belt:

Within the boundaries of these sites identified on the Proposals Map, limited infilling, or redevelopment which meets the following criteria, will not be inappropriate development.

2. Limited infilling should:

  • be for the continuing use of the site within the area designated for this purpose and shown cross-hatched on the Proposals Map,

  • have no greater impact on the purposes of including land in the green belt than the existing development,

  • not exceed the height of existing buildings, and

  • not lead to a major increase in the developed proportion of the site.

3. Complete or partial redevelopment should:

  • result in an improvement to the environment,

  • have no greater impact than the existing development on the openness of the green belt and the purposes of including land within it, and where possible, have less,

  • contribute to the achievement of the objectives for the use of land in green belts, and

  • not exceed the height of the existing buildings, and not occupy a larger area of the site than the existing buildings (unless to do so would achieve a reduction in height which would benefit visual amenity).

Proposals for partial redevelopment will not be approved in the absence of a comprehensive long-term plan for the site as a whole.

The character and dispersal of new buildings in a redevelopment scheme must have regard to the openness of the green belt and the purposes of including land in it, the objectives for the use of land in green belts, the main features of the landscape, and the need to integrate the new development with its surroundings.

Proposals must also take full account of visual amenity, traffic and travel implications, and environmental considerations including nature conservation.

Policy Derivation:

PPG2

Reason and Explanation:

1. This policy sets out the criteria for infilling, partial or complete redevelopment of major existing developed sites in the green belt in accordance with PPG2 Annex C.

2. For the purposes of 3(4) above, the relevant area is the aggregate ground floor area of the existing buildings (‘the footprint’), excluding temporary buildings, open spaces with direct external access between wings of a building, and areas of hardstanding.

3. The sites identified as falling within this policy are consistent with the guidance given in paragraph C1 of Annex C to PPG2.

Area of Coverage:

The relevant sites are defined on the Proposals Map.

GRN9 OUTDOOR ACTIVITIES IN THE COUNTRYSIDE

Outdoor activities and sports, which because of their nature can adversely affect the amenities of residents or other users of the countryside, will be permitted only where all of the following circumstances apply: -

  1. there is no unacceptable increase in noise, vibration, fumes or visual disturbance likely to harm the amenity of nearby residential property or the value of other environmentally sensitive areas or features;

  2. there is no unacceptable increase in traffic flows or congestion such as to be harmful to public safety or the environment, particularly if there would be heavy traffic flows on a minor road through a village or past a significant number of houses;

  3. it would not cause permanent or irreparable damage to the environment or endanger wildlife, people, or property;

  4. there is no conflict with agricultural interests;

  5. there is no harm to the character of the countryside or the local landscape, or there is a positive benefit to a degraded landscape; and

  6. suitable controls over the type of equipment used and the level and hours of operation can be secured through conditions or planning obligations.

Policy Derivation:

PPG17

Reason and Explanation:

Many sports, especially those using motorised vehicles, can create a significant nuisance in their own right as well as attracting large numbers of spectators who may themselves create an intrusion in the countryside. However such sports are very popular and a balance needs to be struck between environmental and sporting interests. This policy sets down criteria for the selection and consideration of sites for these purposes.

GRN10 PROTECTION AND ENHANCEMENT OF URBAN GREENSPACE

The Council will not permit development likely to result in an unacceptable loss of green space within the built-up areas of the borough. Proposals will be assessed in the light of:

  1. the effect of such loss on the level, availability and accessibility of recreational facilities, children’s play provision and public open space in the neighbourhood, taking into account the needs of future generations;

  2. the role that the site plays as part of the existing or proposed Greenway Network of recreational footpaths and cycleways identified on the Proposals Map, or as a link to other green spaces or the countryside;

  3. its landscape and/or nature conservation value;

  4. its value as a buffer zone between other uses, including noise attenuation zones;

  5. its value as a visual amenity or townscape feature in contributing to the character or appearance of the surrounding area;

  6. its importance to the avoidance of town cramming or as a visual break in an otherwise intensively developed area;

  7. any associated proposals for the enhancement of existing facilities nearby or provision of equivalent replacement facilities; and

  8. Its importance as a community resource for formal or informal events.

In areas shown to be deficient in open space, sports or recreational provision in either quality or quantity, development proposals will be expected to contribute to their enhancement or provision

Policy Derivation:

PPG9, PPG12, PPG17

ODPM - Assessing needs and opportunities: A companion guide to PPG17

Reason and Explanation:

1. This policy applies to all those areas of green space within the built areas of the borough (i.e. not shown as green belt on the Proposals Map) which are either visually or functionally open to the public and therefore have an amenity, aesthetic or practical value to the community. This includes land in both public and private ownership. Sites in green belt villages, or covered by green belt policy elsewhere, are not shown on the Proposals Map as being protected green space. Nevertheless, should development proposals arise which are not precluded by policy GRN1 'The Green Belt', it will be necessary for an assessment to be made against the above criteria.

2. Such sites normally make an important contribution to the environmental standards, level of amenity, and quality of life available to residents within the built areas of the borough, especially in those parts of the town which do not have ease of access to open countryside. PPG17 has raised the status of urban open space as an important land use in its own right. Some areas of the borough are however less well provided than others by the different types of open spaces and recreational facilities when assessed against the relevant standards. In deficient areas the protection and enhancement of provision will be a prime consideration when the Council is determining planning applications. An assessment of provision was made in the ‘Open Space Background Paper’ (see below).

3. The policy sets out clear criteria against which proposals for the development of urban green space will be tested and the application of this policy is not limited to land currently in specific use for recreational purposes. Open land which comprises green space in the built area of the town and which does not have planning permission or is not allocated for development, will be subject to assessment against the criteria in this policy if development proposals arise. Proposals involving the redevelopment of brownfield sites will also be assessed taking into account any identified need for additional open space or recreation facility in the locality.

4. In considering whether a development proposal will have a detrimental effect on the level and availability of open space or on the character of an area, or whether there is a requirement to enhance or provide open space, the Council will have regard to an assessment of open space and recreation provision against the Council’s standards, and to a qualitative appraisal of the site and its setting. The quantitative assessment has been revised and updated following re-survey, and in the light of revised PPG17, and was published as a Supplementary Planning Document, ‘Open Space and Recreation Provision’ in 2005. In association with Sport England, the Council has also prepared a Playing Pitch Strategy and its recommendations are reflected in the above SPD. Appendix 2 to the adopted UDP includes a schedule of spaces protected by this Policy, including those sites in Green Belt Villages to which the policy criteria may be applied in accordance with paragraph 1 above. The schedule is correct as at January 2006 and will be updated annually.

5. The object of the policy is to prevent losses of valuable open space and open land within the built areas of the borough, but it is not possible to protect each and every such area regardless of circumstances. Although the value of open land within the built areas can be compared with the value of open countryside in terms of the amenity and quality of life of the borough’s residents, an urban equivalent of ‘green belt’ policy is not allowed for within the planning framework of the development plan.

6. In most cases, in order to protect urban land in private ownership from development in favour of a preference for public open space, the Council must be able to show that it is committed to purchasing the site in question for public use, and has to purchase the land at its development value regardless of the fact that it will be used as open space. The law does not allow a private interest in land to be penalised for the public good;

7. In many instances, therefore, it is likely that the Council will seek to negotiate a compromise between some development and the retention of open land, and to ensure that the open land retained is made fully available for public use.

8. Playing fields, whether public or private, are afforded special status by PPG17 which makes it clear that they should normally be protected from development except in special circumstances. Their protection is the subject of policy GRN11.

9. Proposals for small scale structures which support the existing recreational use of green space, or provide facilities for new recreational uses will need to take these criteria into account to ensure the proposed development is sensitive to the local context.

Area of Coverage:

This policy applies throughout all built areas, town and village, of the borough.

GRN11 PLAYING FIELDS

Development which results in the loss of playing fields will not be permitted except where:

  1. alternative provision of equivalent community benefit in terms of location, quantity and quality is made available;

  2. the proposed development is ancillary to the use of the site as a playing field (e.g. new changing rooms) and does not adversely affect the quantity or quality of pitches and their use;

  3. the proposed development only affects land which is incapable of forming a playing pitch (or part of one);

  4. the playing fields that would be lost as a result of the proposed development would be replaced by a playing field or fields of equivalent or better quantity and quality and in a suitable location or;

  5. the proposed development is for an outdoor or indoor sports facility of sufficient benefit to the development of sport to outweigh the loss of the playing field; and

  6. the needs assessment demonstrates that the site is surplus to requirements in relation to all the functions that open space can perform.

Policy Derivation:

PPG17

ODPM - Assessing needs and opportunities: A companion guide to PPG17

Statutory Instrument 1996 No.1817

Reason and Explanation:

1. Many playing fields, including those belonging to schools, colleges and sports clubs, are not public open space but are invariably perceived as part of the community. School fields in particular are often used out of school hours by the public, and may contribute to the character and amenity of residential areas. In some parts of the borough, school fields are the only or principal areas of green space available, and are therefore especially important assets (for details see the Open Space Background Paper).

2. An aim of this policy is to ensure that the redevelopment of redundant school sites or the disposal of ‘surplus’ playing fields does not take place at the expense of the amenity and character of residential areas, and the needs of local residents for access to open space, especially in those areas particularly dependent on school fields for green space. It is also important to ensure that schools retain sufficient playing fields for their own use, taking into account the needs of future generations.

3. The policy also applies to private playing fields which may be subject to redevelopment proposals even though they are in active use, as their owners seek to create a capital asset by seeking planning permission for development. Such clubs are a valuable recreation resource and merit protection. The criteria adopted in this policy reflect the approach in revised PPG17. The ‘Open Space and Recreation’ Supplementary Planning Document and the Warrington Playing Pitch Strategy referred to under policy GRN10 will make this assessment in the borough. Pending completion of the SPD, an applicant for planning permission should seek to demonstrate through an independent assessment that any facilities that will be lost are surplus to requirements.

4. Appendix 2 to the adopted UDP includes a schedule of spaces protected by this Policy, including those sites in Green Belt Villages to which the policy criteria may be applied in accordance with paragraph 1 above. The schedule is correct as at January 2006 and will be updated annually.

GRN12 OPPORTUNITIES TO IMPROVE OPEN SPACE PROVISION

The following sites are identified as opportunities to improve and extend open space provision and/or the Greenway Network:

Policy Derivation:

PPG17

Reason and Explanation:

1. The Open Space and Recreation Supplementary Planning Document provides a very comprehensive appraisal of the current levels of open space provision across the borough. Provision is compared with recognised standards to enable an assessment of neighbourhoods deficient in public open space to be made.

2. The Open Land Survey which informed the above exercise also identified several unused or derelict sites which presented an opportunity to enhance open space in the town of Warrington, either in quality or quantity.

3. This policy identifies several such sites and registers the Council’s interest in making them available for public use, following environmental improvement as necessary, and subject to the successful conclusion of any necessary negotiations with landowners.

4. All of the sites listed are currently in private ownership, and are largely or wholly unused at present. They are not subject to existing planning permissions for development, and some may not be suitable for development. The majority are in areas where a shortfall in open space currently exists.

5. The acquisition of any or all of these sites could prove costly and may, realistically, be beyond the Council’s reach. The negotiation of lease or access agreements may however be achievable if the co-operation of landowners can be obtained. This in turn may well depend on the aspirations of the owners of individual sites to obtain planning permission for a more profitable use of the site or adjoining land. Such applications for planning permission will be dealt with in the context of all the relevant UDP policies. This particular policy may only be relevant if the Council can demonstrate at the time an application is made that the resources to acquire the site in question are available to put the policy into effect.

6. This policy in itself should not therefore be taken as any guarantee that any or all of the sites listed will not be developed for another purpose. In that event, however, the Council will seek to secure environmental gains by negotiation with the applicants.

7. The land at Well Lane, Penketh, previously listed under the First Deposit Draft policy is now included in the green belt as an associated revision to the UDP.

Area of Coverage:

The specific sites referred to as shown on the Proposals Map. They are:

1. Former sewage treatment works, Kingsway: This site is a key element of the wedge of open land which brings the Mersey Valley into the heart of the urban area of Warrington. It is currently unused and in a semi-derelict condition. The Mersey Way footpath skirts the land. It is owned by United Utilities plc. Proposals for residential development and recreational facilities linked to improvements to Cardinal Newman High School were submitted in 2003.

2. Land adjoining Black Bear Park, Loushers Lane: This land is owned by Greenalls and adjoins Black Bear Park, from which it is accessible. The site can also play an important role in the Greenway Network and if development proposals come forward which affect this site, the Council will seek to safeguard these interests by negotiation with the applicant.

3. Land south of Penketh Road: This unused area of open land adjacent to Eagle Sports Club, was identified in the original survey as potential public open space (in conjunction with area 5 below), and was again located in a deficient area. The site is now in active use as a playing pitch.

4. Whittle Brook, south of Penketh Road: The Whittle Brook linear park extends currently from west of Lingley Green Avenue to the A57 at Whittle Avenue. Its continuation south of Penketh Road to join the St Helens Canal is an established aim of open space/footpath development in this area, and a planning appeal decision has supported this aim.

5. Land at Station Road, Penketh: This site is located well within the residential area of Penketh, and has potential for public open space if brought into public ownership. There are understood to be severe development constraints.

6. Land at Longshaw Street, Dallam: This vacant land is owned by English Partnerships and is a link between Dallam and the continuation of Sankey Valley Park north of Cromwell Avenue.

7. Land at Marsden Avenue, Westy: This is an old waste tip, badly contaminated, previously believed not to be suitable for development. It may be a good site for Mersey Forest Planting. There has however recently been some interest in developing the site for housing.

GRN13 RIVERSIDE AND CANALSIDE DEVELOPMENT

Development adjoining or near to rivers or canals will not be permitted if it would have an adverse effect on nature conservation, fisheries, landscape, public access, or water-based or waterside recreation.

Development which visually and physically adjoins waterways will be required to exploit and enhance their recreational, wildlife and amenity value, and wherever possible should provide for safe public access to and along the waterside. Access for operational and maintenance purposes should also be safeguarded and buffer strips provided where appropriate.

Policy Derivation:

Environment Agency Model Land Use Policies

2000/60/EC Water Framework Directive

Reason and Explanation:

1. The Council recognises that rivers and canals are of great importance for water resources, water quality, nature conservation, fisheries, recreation and the character of the landscape. In many instances land adjoining or near to rivers is an important source of open space and frequently also forms links or ‘green chains’ between areas of open space, often across borough boundaries. These links can be crucial for the survival or enhancement of wildlife.

2. The Council will generally support initiatives and proposals which will result in the conservation or enhancement of the natural elements of the riverine environment, result in landscape improvements, or which promote public access and water-based or waterside recreation.

3. In terms of physical built development particular attention will be paid to the siting and orientation of buildings and public space in new developments, with the emphasis on increasing public access to waterside locations and enhancing their appearance.

4. The Council will have regard to the objectives of the Mersey Basin Campaign in considering development proposals relating to land adjoining the River Mersey and its tributaries.

5. It is acknowledged that in the interest of public safety it will not always be appropriate to allow access to the banks of the Manchester Ship Canal.

6. The maintenance of public access to the waterside safeguards the future possible use of waterways as a sustainable means of transport.

7. The Environment Agency has published guidance relating to the issue of buffer strips

GRN15 SITES OF INTERNATIONAL IMPORTANCE FOR NATURE CONSERVATION

The following sites have been designated as candidate European Sites of international importance (Special Areas of Conservation):

  1. Rixton Clay Pits

  2. Risley Moss

  3. Holcroft Moss

Proposals for development which may affect these sites will be subject to the most rigorous examination. Development or land use change not directly connected with or necessary to the management of the site and which is likely to have significant effects on the site (either individually or in combination with other plans or projects) and which would affect the integrity of the site, will not be permitted unless the Council is satisfied that:

  1. there is no alternative solution; and

  2. there are imperative reasons of over-riding public interest for the development or land use change.

Where the site concerned hosts a priority natural habitat type, and / or a priority species, development or land use change will not be permitted unless it is necessary for imperative reasons of human health or public safety, or for benefits of primary importance for the environment.

Where development is permitted the Council will consider the use of conditions or planning obligations to ensure the protection and enhancement of the site’s nature conservation interest.

GRN16 SITES OF NATIONAL IMPORTANCE FOR NATURE CONSERVATION

The following sites have been designated as Sites of Special Scientific Interest:

  1. Risley Moss

  2. Rixton Clay Pits

  3. Woolston Eyes

  4. Holcroft Moss

Proposals for development in or likely to affect these sites will be subject to special scrutiny. Where such development may have an adverse effect, directly or indirectly, on the SSSI it will 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.

Where development is permitted, the Council will consider the use of conditions or planning obligations to ensure the protection and enhancement of the site’s nature conservation interest.

GRN17 SITES OF LOCAL IMPORTANCE FOR NATURE CONSERVATION

The following sites have been designated as of local significance for nature conservation:

Development likely to have an adverse effect on these sites will not be permitted unless it can be clearly demonstrated that there are reasons for the development which outweigh the need to safeguard the substantive nature conservation value of the site or feature.

Where development is permitted which would damage the nature conservation value of the site or feature, such damage will be kept to a minimum. Where appropriate, the Council will consider the use of conditions or planning obligations to provide appropriate compensatory measures.

Policy Derivation:

PPG9

English Nature model policies

Reason and Explanation:

1. This group of policies are designed to protect sites of recognised nature conservation value (ecological, geological, geomorphological). The conservation of such sites is vital to the preservation of wildlife heritage. The policies reflect the advice in national planning guidance that the degree of protection afforded will vary according to the status of a site. Hence local sites do not carry the same level of protection as internationally important sites. The international sites at Risley Moss and Holcroft Moss are two of three sites which make up the Manchester Mosses Special Area of Conservation.

2. The sites listed are correct as at 1 January 2006. Any additional sites that may be identified after this date will also be protected by these policies as soon as they are designated.

3. Many of the sites identified in previous plans were primarily in the rural areas of the borough. The Council has given high priority to the identification of further sites whose local value should be protected and nurtured, especially in the urban areas where they can contribute to the overall protection and provision of open space, provide access to nature, and enhance local environmental quality.

4. Further information can be found in the Council’s Nature Conservation Strategy.

GRN18 KEY BIODIVERSITY HABITATS AND PRIORITY SPECIES

Development which may adversely affect the integrity or continuity of UK Key habitats or other habitats of local importance as listed below, or adversely effect UK Priority Species or other species of local importance, or which are the subject of Local Biodiversity Action Plans as listed in appendix 9 will only be permitted if it can be shown that the reasons for the development clearly outweigh the need to retain the habitats or species affected, and that mitigating measures can be provided which would reinstate the habitats or provide equally viable alternative refuge sites for the species affected.

Appropriate management of these habitats and sites supporting any such priority species will be encouraged generally and particularly by the imposition of conditions on planning permissions, by the use of planning obligations and by entering management agreements with landowners and developers where appropriate.

Policy Derivation:

PPG9

Reason and Explanation:

The key to the protection of wildlife is the protection of the habitat on which it depends. Protection of wildlife is not an objective which applies only in specially designated areas. All the above habitats lend diversity to the local environment in both landscape and nature conservation terms. Wetlands and ponds are especially important in providing wildlife habitats. Warrington Borough contains hundreds of old marl ponds of high nature conservation value and the Mersey Estuary provides wetland habitats of international importance.

In 1992, the UK Government signed the Global Biodiversity Convention at the Earth Summit in Rio De Janeiro. In 1994, the Government's response to its Rio commitment was to appoint a Biodiversity Steering Group to identify target species and habitats for the UK and prepare action plans for each. Target species and habitats are those that are considered under threat internationally or have been subject to rapid decline in the UK. In 1995, the Steering Group published its findings and initially endorsed action plans for over 100 species and 14 habitats; this figure has now risen to almost three hundred species and over 25 habitats.

The NW England Biodiversity Steering Group published 'A Biodiversity Audit for North West England' which listed UK target species and habitats for the region; some 17 priority species and 6 Key Habitats (see appendix 9) were identified for the local authority area of Warrington.

The Council is a committed partner to the 'Countdown Biodiversity Programme – A Biodiversity Audit with Local Plans for the Conservation of Wildlife of the Cheshire Region'. This county-wide initiative advances Biodiversity action plans at the local level (see appendix 9).

Reason and Explanation:

1. It can be an offence to intentionally kill, injure or take any wild bird or take, damage or destroy its nest whilst in use. It is not an offence if the act was the incidental result of a lawful operation, such as a planning permission, and could not reasonably have been avoided. The Council will, therefore, require, as appropriate, a nesting bird survey and may delay commencement works through planning conditions to fall outside of the breeding season.

2. The presence of a protected species is a material consideration when the Council is considering a development proposal which, if carried out, would be likely to result in harm to that species or its habitat. Suitable precautions can be required by conditions on planning consents. English Nature has published specific ‘Great Crested Newt Mitigation Guidelines’ (2001) which will be relevant in parts of the borough.

GRN20 WILDLIFE CORRIDORS

Development within or adjacent to major wildlife corridors will not be permitted if it is likely to destroy or harm their integrity, and will be allowed if it preserves or enhances their role and value through good design and appropriate natural landscaping.

Policy Derivation:

PPG9

Reason and Explanation:

1. Linear biological features can act as ‘corridors’ along which wildlife can move and live. Wildlife corridors serve as the most effective means of enhancing wildlife diversity within the borough’s built-up areas. Corridors can be damaged or rendered unviable by reduction in their width or by complete severance. Opportunities will also arise through development proposals to enhance or extend the network of wildlife corridors.

2. The Council’s Nature Conservation Strategy has identified the Mersey Valley Corridor and the Sankey Valley Park as major wildlife corridors and these are shown on the Proposals Map. The primary consideration in the definition of these major wildlife corridors is the maintenance of continuous linkage between the best sites for wildlife and between such sites and the Council’s Greenway Network; thus facilitating ease of movement by a wide range of animal, bird, insect and plant species into parks and open spaces. While some sites within the designated corridors, if examined in isolation, may have limited wildlife value, all have potential for improvement, either through the Council’s own environmental initiatives or through development control opportunities.

Mersey Valley Corridor

This constitutes a wide tract of land (exceeding 2kms in places) extending across the borough from Fiddlers Ferry Power Station in the west, to Hollins Green and the flood plain of the River Bollin in the east. Its value lies in the mix of river valley habitats, notably wetlands, in the context of the Mersey Estuary as a whole - one of the largest estuaries in Europe and supporting internationally important numbers of birds.

The boundary definition of the corridor is based on: -

  • Compatibility and linkage with the borough’s greenway network, green spaces and green belt;
  • Compatibility with wildlife corridors identified in ‘A Nature Conservation Strategy for Warrington’;
  • Location, protection and linkage of designated nature conservation sites;
  • Compatibility with the ‘Mersey Estuary Management Plan’;
  • Linkages of existing riverine and wetland habitats;
  • Routes of major rivers and canals;
  • Linkage to existing or potential wildlife corridors by neighbouring authorities.

Sankey Valley Linear Park

This important corridor runs north-south for over 6 kilometres through Warrington, linking the green belt to the north, to the River Mersey in the south. It is characterised by ‘new town’ ecology-led landscaping adjoining Sankey Brook and the St Helens Canal, and is important for flora and fauna.

The boundary definition of the corridor is based on: -

  • Compatibility and linkage with the borough’s greenway network, green spaces and green belt;
  • Compatibility with Wildlife Corridors identified in ‘A Nature Conservation Strategy for Warrington’;
  • The Sankey Valley Linear Park boundary;
  • Sankey Brook and its associated flood plain.

3. Secondary wildlife corridors or links are also important and these primarily consist of:

a) River, canal and brook corridors

b) Transportation network green corridors

c) The hedgerow network

4. These are not shown on the Proposals Map as the detailed research necessary to define their extent and importance has not yet been commissioned. Where development proposals arise their nature conservation importance will however, be assessed against the provisions of other relevant UDP policies, including LUT15, GRN10, and GRN21.

5. The object of the policy is to minimise the impact of new development on areas identified as wildlife corridors, and not to protect each and every such area regardless of circumstances. The policy does not imply a general presumption against all development, especially where the site in question is in private ownership. The limitations on the Council explained in the reason and explanation to policy GRN21 apply equally to this policy. The Council will seek to enhance the wildlife corridor value of the site in these circumstances. Minor development, such as the provision of small sub-station sites in heavily built up areas of the borough which often require to be sited in ‘green’ areas where there is no suitable alternative, is not prejudiced by this policy.

Area of Coverage:

Major corridors are shown on the Proposals Map. Secondary corridors occur throughout the borough.

GRN21 PROTECTION OF THE NATURE CONSERVATION RESOURCE

Development proposals affecting protected sites (policies GRN15, GRN16 & GRN17), threatened habitats (policy GRN18) or wildlife corridors (policy GRN20), should be accompanied by:

  1. a site survey where necessary to identify features of nature conservation importance;

  2. an assessment of the likely impacts of the development proposed;

  3. proposals for the protection and management of features identified for retention; and

  4. proposals for compensating for features damaged or destroyed during the development process.

Policy Derivation:

PPG9

Reason and Explanation:

1. This policy makes it clear to developers that, where there is reason to believe that a site is of nature conservation importance, the Council will expect proposals to be accompanied by a detailed appraisal of the nature conservation resource present and of measures designed to protect, enhance or replace that resource as appropriate. Consideration of applications where this policy is relevant will seek to ensure that there is no net loss of the nature conservation resource as a result of development.

2. The policy applies alike to designated areas and other land where conservation value should be maintained.

3. The Council will negotiate with developers to safeguard nature conservation interests whenever they are threatened by development proposals. Provided development can be subject to conditions or a planning obligation that will effectively limit its impact on wildlife habitats or important physical features, applications will not normally be refused permission on nature conservation grounds alone.

4. Ecological surveys to nationally recognised standards will be required. Habitat and species surveys must be completed at the correct time of year and of sufficient repetition or intensity, as appropriate, to permit determination of nature conservation value.

GRN22 PROTECTION AND ENHANCEMENT OF LANDSCAPE FEATURES

Development proposals should identify and protect important landscape features, such as walls, trees, hedgerows, streams and ponds and, whenever possible, incorporate these features into the layout and landscape of the development. Where the loss of trees, hedgerows or ponds cannot be avoided, replacement planting or pond construction will be required.

Hedgerow Regulations, 1997

Reasons and Explanation:

1. It is a duty of the development plan to conserve the natural beauty and amenity of the land. This includes retaining and enhancing the natural assets of sites which come forward for development or redevelopment, and an effective way of achieving this is to locate landscape or open space areas so as to incorporate those features. Wherever possible, the siting of open space should also take account of features and open spaces on neighbouring or nearby sites and the potential for creating visual and functional network links.

2. Trees and hedgerows are of particular value in terms of visual amenity as well as for nature conservation. The retention and protection of existing valuable trees and hedgerows is important in helping to retain the character of the locality and to enhance the visual quality of new development and its setting. Tree replacement and landscape enhancement through tree planting should utilise locally native species where appropriate.

3. The Hedgerow Regulations 1997 give hedgerows separate statutory protection. Notice must be given to the Council before a hedgerow covered by the regulations can be removed. The Council will then assess the importance of the hedge and issue consent to remove or a retention notice as appropriate.
