HERTFORDSHIRE COUNTY COUNCIL DEVELOPMENT CONTROL COMMITTEE TUESDAY 18 JANUARY 2011 AT 10:00 AM Agenda No. 3 WELWYN HATFIELD BOROUGH APPLICATION FOR RETROSPECTIVE PLANNING PERMISSION TO CONTINUE TO USE SITE FOR WASTE USE (FERROUS AND NONFERROUS STORAGE, SORTING AND TRANSFER) AND FOR PLANNING PERMISSION TO DISMANTLE AND DE-POLLUTE END-OF-LIFE VEHICLES, AND TO ERECT A WALL FOR WGC METALS AT BRIDGEFIELDS, WELWYN GARDEN CITY, HERTFORDSHIRE AL7 1RX Report of the Director of Environment and Commercial Services Author: Chay Dempster Tel: 01992 556256 Local Member: Malcolm Cowan 1. Purpose of Report 1.1 To consider planning application ref. 6/2095 -10 for the processing of scrap metal and the storage, dismantling and de-pollution of end of life vehicles at Welwyn Garden City Metals Ltd, Bridgefields, Welwyn Garden City, Herts. 2 Summary 2.1 This is a retrospective planning application for the use of the site for storage, sorting and transfer of ferrous and non-ferrous metals and for planning permission for the de-pollution and dismantling of end of life vehicles (ELV). Planning permission is also sought to erect a replacement wall of 3m in height along the site’s south western boundary. 2.2 WGC Metals currently uses the site for recycling metals. This use is understood to have subsisted for a number of years operating as B2 industrial use. The application seeks to regularise the metal recycling use and introduce the processing of end of life vehicles. 2.3 The site has two existing buildings including a large warehouse for storage of recycled metals adjoining the southern boundary and a smaller workshop for de-pollution of end of life vehicles adjoining the western boundary. The baling machine and car storage areas are located in the open central part of the site. 2.4 The ELV operation involves bringing vehicles to the site where they are de-polluted (removal of oil, fuel, gases, and batteries). This part of the operation takes place within a dedicated building. Useful car parts are removed and stored in the warehouse for recycling. The vehicles are WGCMetals. Application ref: 6/2095-10 Site ref: CM909 1 then baled and stored in the open part of the site before being removed for recycling. 2.5 The main issues in the determination of this application are: • • • • waste and employment policy the need for waste recycling facilities noise traffic/highways 3. Conclusion 3.1 This retrospective application proposes use of the site for processing end of life vehicles. The use of the site for metal recycling and processing ELVs would meet a demonstrable need and regularise the use of the site. Appropriate planning conditions can be used to control the use of the site. 3.2 The use of the site would not have a negative impact on the character of the industrial area and would not restrict supply of suitable sites for B1, B2 or B8 in the area. 3.3 The proposed number of vehicles would not have a significant impact on the road network. The limited use of the baler for up to 3 hours per day would limit the impact of noise. 3.4 It is considered that the proposal meets with the aims and objectives of Waste Local Plan Policy 13 and Welwyn Hatfield policies R1 and EMP1 and 2. 3.5 The report concludes that the Director of Environment and Commercial Services should be authorised to grant planning permission subject to the following conditions: a) b) c) d) hours of operation the permitted hours of operation of the site are Monday to Friday 7am to 4pm; 7.30 am to 11.45am on Saturdays. No permitted use on Sundays, or Public and Bank Holidays. use of the crusher / baler the permitted hours of use of the baler / crusher are restricted to 3 hours on any one day. There shall be no use of the baler / crusher outside the normal hours of operation (condition a) HGV movements there shall be no more than 10 HGV lorry movements (exceeding 7.5 tonnes) in any 24 hour period (5 in, 5 out) from Monday to Friday and 6 HGV lorry movements (3 in, 3 out) on Saturdays. There shall be no HGV lorry movements outside the hours of operation set out in condition a). stockpiles the maximum height of any stockpiles shall not exceed 5 metres. The maximum height of any stockpile of tyres shall not exceed 3 metres WGCMetals. Application ref: 6/2095-10 Site ref: CM909 2 e) f) g) h) i) j) noise monitoring and attenuation scheme details of a scheme for monitoring operational noise of the baler shall be submitted for approval, to include appropriate noise attenuation measures. noise other than the baler / crusher there shall be no use of mechanical tools outside of buildings contaminant storage details of de-pollution storage containers/tanks (including their location on the site) shall be provided within 3 months of the date of this permission; the withdrawal of permitted development rights so that planning permission is required for further buildings. parking space to be provided and maintained for parking in connection with the site in accordance with plan referenced 7888010062/PA/03 Rev A3 preliminary risk assessment for flood risk details shall be submitted for approval WGCMetals. Application ref: 6/2095-10 Site ref: CM909 3 4 Site Description 4.1 The application site is located in the corner of an existing industrial site served by its own estate road (Bridgefields leading to Tewin Road) which serves four other premises, ABD Mechanical and Electrical Engineering, Insight, Xerox, and Eurotrade Plastics. 4.2 To the west of the site is a Royal Mail sorting office plus a large office/ distribution building each with access onto Bessemer Road. To the south of the site is a gas storage facility operated by Transco. 4.3 The site is located approximately 850 metres north-east of the railway station and 370 metres from the A1000 with links to the A1(M) to the west and the B1000 to Hertford to the east. 4.4 The application site is approximately 0.41 hectares in area and is completely covered with a concrete hardstanding. The southern boundary is marked by a 2.4m high palisade fence. There is a substantial fence constructed of railway sleepers between the site and the sorting office. 4.5 There are two existing buildings on site, the smaller workshop building is currently used for vehicle de-pollution, and the larger warehouse building is used to store recycled metals and car parts. 4.6 The site is within a designated employment area in the Welwyn Hatfield Local Plan, and is some considerable distance from the nearest residential properties. Proposed development 4.7 This application proposes the use of the site for recycling metals and processing end of life vehicles (ELV). It is understood the site has been used for metal recycling for a number of years and that this has operated under a B2 Use. It is understood the site is currently permitted by the Environment Agency for metal recycling. 4.8 The application proposes to erect a 3 metre high brick wall along the western boundary which is required by the Environment Agency to meet the terms of the permit regime. 4.9 The application proposes 6 parking spaces on land immediately to the north of the application for staff and visitors on land controlled by the applicant. No alterations are proposed to the highway access to Bridgefields or Tewin Road. 4.10 It is estimated the site would handle 25,000 tonnes of waste each year. This equates to around 80 tonnes per day (6 days a week, 52 weeks a year). The application proposes a maximum of 160 vehicle movements WGCMetals. Application ref: 6/2095-10 Site ref: CM909 4 per day (80 in, 80 out). The proposed hours of operation are 7.30am to 5pm Monday to Friday and 7.30am to 11.45 on Saturdays. 4.11 As part of the dismantling process ELVs would be brought to the application site where they would be weighed on a weighbridge before being de-polluted within one of the existing buildings. Valuable parts would then be removed for re-use. The vehicle would then be baled and stored before being removed from site for recycling. 4.12 The process of recycling ferrous and non-ferrous metals involves metals brought to the site by small flat bed trucks, taken to the weighbridge (as required by the waste acceptance procedures) and separated in to ferrous and non-ferrous components. 4.13 The non-ferrous metals are placed in steel tipping skips and taken to a special sorting area at the rear of the warehouse. Metals are separated by type then cleaned and placed into containers awaiting dispatch for sale. Ferrous metals are deposited at the rear of the site in a dedicated sorting area where they are sorted manually or mechanically using a crane/grab and separated into the appropriate storage area. 4.14 The machinery for the ELV process consists of a de-pollution unit located in the smaller workshop building, a mobile crane/ grab, and a mobile shearer compactor (press and shear). The baler is fitted to the back of an articulated lorry which can be moved around the site and to alternative sites if required. 5. Statutory Consultations 5.1 Welwyn and Hatfield Borough Council objects to the development on the following grounds: ‘The application site is located within a designated employment area where the proposed change of use would be contrary to Policy EMP2 of the Local Plan stating that proposals for uses other than B1, B2 or B8 should not be permitted’. ‘The proposed use is Sui Generis and does not fall within the Classes B1, B2 and B8. Policy EM1 does allow some flexibility to meet the needs of such uses and a pragmatic approach should be taken due to the specific nature of the proposed use and its location in the middle of the employment area. However the onus is entirely on the applicant to demonstrate why such a use should be allowed in this area and insufficient information has been submitted to demonstrate this’. ‘The only justification within the submission is that the application states that the proposed use would still generate employment uses and so can still be considered to accord with the intention of the policy of retaining employment uses. It is considered that this is not a sufficient reason to warrant an approval of the proposal, based on the policies of WGCMetals. Application ref: 6/2095-10 Site ref: CM909 5 the local plan, in this location and it is therefore considered that insufficient justification has not been given which addresses the objection to the principle of development’. 5.2 Welwyn Hatfield Environmental Health department has not responded to this application, however they provided the following comments on the withdrawn application (6/1549-08): Matters preventing land and water contamination will be addressed by the Environment Agency. It appears that the nearest offices likely to be affected by noise from the operations are approximately 75m away from the site. Outside the façade of the offices noise levels are likely to be in the region of 65dB LAeq and 52dB internally. Peak noise during the 81 sec cycle may generate internal noise levels in excess of 64dB increasing the likelihood of complaints alleging statutory noise nuisance. Occasional use of the baler is unlikely to generate problems, although regular use throughout the day could result in complaints. 5.3 The Environment Agency advises that any permission should include conditions to ensure that (1) an acceptable scheme is submitted to prevent contamination of the site; (2) proposals for remediation of the site in the event of pollution events being submitted for approval, and (3) a scheme for the disposal of foul and surface water being submitted for approval. 5.4 Hertfordshire County Council as Highway Authority has no objection subject to a condition that there shall be no more than 10 HGV lorry movements (5 in, 5 out, lorries exceeding 7.5 tonnes) at the site on any one working day, and 6 HGV lorry movements (3 in, 3 out) Saturday mornings). 5.5 The highway authority notes the ELVs would be brought to the site on flat bed trucks. The vehicles would be removed using a forklift and placed in the de-pollution building. The de-polluted vehicle would be placed into the baler by the forklift. The baled vehicles would be stored on site prior to removal. HGV articulated vehicles currently reverse into the site from Bridgefields. This process is managed by a member or staff. HGVs exit the site in a forward gear. The recycled metals are removed from the site by one HGV which is owned by the applicant. 5.6 It is anticipated that between 5 and 10 ELVs would be processed each day. This would involve up to 10 flat bed trucks (non HGV) delivering to the site per day. The average ELV shell weighs around 1 tonne and HGVs are limited to 25 tonnes. It is therefore anticipated that there would be no more than 1 HGV movement every two days related to ELV processing. WGCMetals. Application ref: 6/2095-10 Site ref: CM909 6 Third Party Comments 5.7 In total 67 consultation letters were sent to surrounding properties (dated 22 September 2010) and a site notice erected at the front of the site (dated 10 October 2010). 2 objection letters have been received highlighting the following concerns: increased level of noise The baling machine generates noise and cause considerable nuisance, particularly noticeable during the summer months when windows are open increased number of large vehicle movements. up to 100 tonnes of waste would enter the site and 100 tonnes leaving the site each day, dust and air pollution - adjoining users will not be able to open windows without suffering the affects potential water course pollution 6 The Development Plan 6.1 The following polices are relevant to the determination of this application: Hertfordshire Waste Local Plan 1995- 2005 Waste Policy 1 – Sustainable Development Waste Policy 2 – Need for waste management facilities Waste Policy 13 – Criteria for re-use, recovery, recycling and transfer of waste (except green waste composting) outside areas of search Waste Policy 40 – Noise from Waste Management Operations Waste Policy 43 – Traffic Welwyn Hatfield District Plan 2005 Policy R1 (Maximising the Use of Previously Developed Land) Policy EMP1 (Employment Areas) Policy EMP2 (Acceptable Uses in Employment Areas) 7 Planning Considerations 7.1 The main issues in determination of this application are: • • • • waste and employment policy the need for waste recycling facilities noise impact traffic/highways WGCMetals. Application ref: 6/2095-10 Site ref: CM909 7 Waste / Employment Policy 7.2 Policy 13 of the Hertfordshire Waste Local Plan identifies appropriate locations for waste facilities (outside specific areas of search) to include land within or adjacent to established or proposed general industrial areas. The site is therefore considered to be appropriate for metal waste recycling in terms of Policy 13. 7.3 Policy EMP1 of the Welwyn Hatfield District Plan states that non Class B uses will only be permitted within existing employment areas where existing employment land is no longer required to meet future employment requirements. Policy EMP2 (Acceptable Uses within Employment Areas) states that proposals for B1, B2 and B8 development will be permitted within designated employment areas provided that the proposal is satisfactory in terms of transport infrastructure and adequate parking, servicing and access and does not impact on residential properties. 7.4 The processing of scrap metal and end of life vehicles is deemed to fall within a sui generis use because the nature of the activity is unique. However the operation would share some similarities with B1 (General Industry) and B2 (Light Industry) in terms of employment and traffic generated. It is noted that B1 and B2 uses cover the full range of industrial activities, to include uses such as a ‘non ferrous metals baling place (from scrap, and ancillary storage thereof) not related to a scrapyard’. 7.5 In terms of employment and traffic generation the operation is set to employ 9 people and would generate up to 160 vehicles movements per day (80 in, 80 out). 7.6 The sui generis operation of the site for metal recycling and processing end of life vehicles is compatible with other Class B uses in the area in terms of traffic and employment generated. Adequate parking, servicing and access are provided and the proposed would not impact on residential properties. 7.7 The limited size of the site together with the generally poor condition of the buildings and corner location of the site are likely to limit its appeal to other potential users. It is noted that there are a number of alternative B1/B2 sites in the vicinity of the site currently to let. 7.8 As such it is considered that the proposal accords with Waste Policy 13 and policies EMP1 and 2 of the local plan. Need for the development 7.9 The application states that this type of development is needed because of regulations requiring manufacturers to reuse/ recover at least 85% of ELVs made after 1986 (rising to 95% by 2015). The aim of the WGCMetals. Application ref: 6/2095-10 Site ref: CM909 8 regulations is to reduce the amount of non-recyclable waste arising from scrapping vehicles. 7.10 It is estimated that ELV waste generated in Hertfordshire will increase from 48,000 tonnes in 2010 to 55,000 tonnes by 2015 and 62,000 by 2020. 7.11 Taking this into account there is clearly a long term need for this type of facility in Hertfordshire and there is an existing and demonstrable need for this specific facility. 7.12 Additional benefits of facilities for ELV processing is that motor parts are re-used rather than vehicles being scrapped as a whole. Waste is divided into the separate waste streams avoiding environmental pollution and waste is moved up the waste hierarchy. 7.13 It is noted that the alternative locations in the vicinity of the site (sites which have specific planning permissions for handling scrap metal or ELVs) are located at Welham Green (Travellers Lane, Sovchem Ltd), Hitchin (Wallace Way, H Williams) Cole Green (B + T Motors) and Kings Langley (ASM). The application site is well located to serve the local catchment area. Noise 7.14 Waste Policy 40 states that where a waste management facility is likely to cause significant noise intrusion to existing noise sensitive development planning permission will not be granted unless noise can be adequately controlled by conditions. 7.15 The potential noise sources relate to metal import and export, distribution of materials on the site, and metal sorting, shearing and crushing. The principle noise source is associated with the processing of a mobile scrap metal crusher/baler. 7.16 The crusher / baler is proposed to operate continuously for up to 3 hours per day at a rate of up to 10 cycles per hour lasting approximately 81 seconds (13.5 minutes per hour of operation). 7.17 The submitted noise impact assessment uses predictive modelling to determine the noise received at the nearest properties north of the site (Communications Court and Insight) to be between 62 and 63dB LAeqT. This noise level is slightly above the existing measured ambient daytime noise level which averages 61dB (measured at 15 minute intervals through the day). 7.18 The noise impact assessment concluded that while the baler would be clearly audible during operation it should not be a dominant noise source. The assessment concludes that occupants of the WGCMetals. Application ref: 6/2095-10 Site ref: CM909 9 Communications Court and Insight offices would not be unduly affected by operational noise when windows are open. 7.19 It is noted that use of the baler will be limited to times when sufficient ELVs are available on site and this will vary based on demand. As such the baler may be used for up to 3 hours per day but it is unlikely it would be used every weekday. 7.20 The two objections on noise grounds are from occupiers of units on the Brownfields industrial estate located east of Tewin Road. Taking into account the existing ambient noise levels and the limited hours of use/ operational cycle of the baler it is considered there would not be an unacceptable noise impact on properties in the vicinity of the site. The recommended condition requires further noise monitoring to determine whether further mitigation would be required. Highways 7.21 Waste Plan Policy 43 states that the county council will take into account the effect of lorry movements on local communities/ residential areas and impose limits on the number of lorry movements where necessary. 7.22 The proposal would result in a relatively high number of non-HGV movements throughout the day although the majority would be related to the existing scrap recycling use. It is considered that a relatively small number of movements would be related to ELV processing, which is estimated to be between 5 and 10 ELVs per day. 7.23 The overall level of traffic generated would be similar to many B1, B2 and B8 uses. The highways authority is satisfied that subject to the condition restricting the numbers of HGV vehicles the development would be acceptable from a highways perspective. WGCMetals. Application ref: 6/2095-10 Site ref: CM909 10 8 Conclusion 8.1 The application site is located within an employment area (as identified in the Welwyn Hatfield District Plan). The use of the site for storage, sorting and transfer of ferrous and non-ferrous metals and for the depollution and dismantling of end of life vehicles is considered compatible with this part of Welwyn Garden City industrial area. 8.2 The use of the site for metal recycling and processing ELVs would meet a demonstrable need and regularise the use of the site. Appropriate planning conditions are proposed to control activity at the site. 8.3 The operation is relatively small scale and the impacts of noise and traffic are likely to be minimal taking into account the surrounding industrial uses. 8.4 For the reasons set out in the report it is concluded that the Director of Environment and Commercial Services should be authorised to grant planning permission subject to the following conditions: k) l) m) n) o) p) q) r) s) hours of operation the permitted hours of operation of the site are Monday to Friday 7am to 4pm; 7.30 am to 11.45am on Saturdays. No permitted use on Sundays, or Public and Bank Holidays. use of the crusher / baler the permitted hours of use of the baler / crusher are restricted to 3 hours on any one day. There shall be no use of the baler / crusher outside the normal hours of operation (condition a) HGV movements there shall be no more than 10 HGV lorry movements (exceeding 7.5 tonnes) in any 24 hour period (5 in, 5 out) from Monday to Friday and 6 HGV lorry movements (3 in, 3 out) on Saturdays. There shall be no HGV lorry movements outside the hours of operation set out in condition a). stockpiles the maximum height of any stockpiles shall not exceed 5 metres. The maximum height of any stockpile of tyres shall not exceed 3 metres noise monitoring and attenuation scheme details of a scheme for monitoring operational noise of the baler shall be submitted for approval, to include appropriate noise attenuation measures. noise other than the baler / crusher there shall be no use of mechanical tools outside of buildings contaminant storage details of de-pollution storage containers/tanks (including their location on the site) shall be provided within 3 months of the date of this permission; the withdrawal of permitted development rights so that planning permission is required for further buildings. parking space to be provided and maintained for parking in connection with the site in accordance with plan referenced 7888010062/PA/03 Rev A3 WGCMetals.

Background information used by the author in compiling this report Planning application reference 6/1549-08 Consultee responses Relevant policy documents Appendix 1 – Relevant development plan policies HERTFORDSHIRE WASTE LOCAL PLAN 1995- 2005 (ADOPTED JANUARY 1999) WASTE POLICY 1 – SUSTAINABLE DEVELOPMENT In identifying land or considering proposals for waste management development, the County Council will have regard to the extent to which the development is sustainable in form and location and helps to conserve resources of land, water, materials, energy and the environment and minimises traffic congestion, travel distances, waste generation and pollution. The County Council in dealing with waste management will give preference to the location of waste recycling, handling, reduction and disposal facilities as close as practicable to the origin of the waste. WASTE POLICY 2 – NEED FOR WASTE MANAGEMENT FACILITIES The establishment of facilities for handling, transfer, treatment and disposal of waste (waste management facilities) will be supported provided that in order to accommodate the equivalent of Hertfordshire’s own waste arisings, there is a clearly established need for additional capacity and facilities of the kind that the proposed development would provide, which outweighs any material agricultural, landscape, conservation or environmental interest affected by the proposal. Applications which would not meet the environmental and planning standards contained in other policies of the development plan, including those related to quality of design, will not be permitted. WASTE POLICY 13 – CRITERIA FOR FACILITIES FOR RE-USE, RECOVERY, RECYCLING, AND TRANSFER OF WASTE (EXCEPT GREEN WASTE COMPOSTING) OUTSIDE AREAS OF SEARCH WGCMetals. Application ref: 6/2095-10 Site ref: CM909 12 Proposals for facilities to re-use, recover, transfer and recycle waste outside preferred areas of search, or for additional categories of waste management within the areas of search, will be permitted subject to compliance with waste policy 2 and provided the proposals: i) minimise impact on local or natural environments; ii) have or could secure ready access to the main road network, or a rail or water link, avoiding, as far as possible, major residential areas; iii) in the case of large plants, are where visual and landscape impact is not a critical issue; iv) serve Hertfordshire’s main population and employment areas; and v) are preferably on land falling into one of the following categories: a) land allocated for development, or subject to potential redevelopment, or on despoiled land; b) within or adjacent to existing waste management facilities such as household waste sites or waste transfer stations; c) within or adjacent to an established or proposed general industrial area (employment areas identified in district local plans with a significant proportion of b2/b8 uses or with major developments such as power stations); d) within or adjacent to compatible land uses such as local authority depots, open storage uses, sewage works and mineral processing plant (for the life of the plant in the case of temporary permissions or plant on mineral working sites). In all cases, proximity to existing and proposed residential areas will be taken into account. WASTE POLICY 40 - NOISE FROM WASTE MANAGEMENT OPERATIONS Where the county council considers that a waste management proposal is likely to cause significant noise intrusion to existing noise sensitive development or constrain planned noise sensitive development, planning permission will not be granted unless the applicant is able to demonstrate that no significant noise intrusion, or constraint arising from noise, will occur, or that any such problem can be adequately controlled by condition. Conditions may include, amongst other matters: • control of working hours; WGCMetals. Application ref: 6/2095-10 Site ref: CM909 13 • measures to reduce the impact of noise emission from operations; • a requirement for a scheme to be submitted to and approved by the planning authority specifying a programme of work and site layout designed to reduce noise levels at noise sensitive locations, construction of baffle mounds and erection of acoustic fencing; • limits on daytime noise emission from the development. Day time noise levels, at noise sensitive properties used as dwellings, of no more than 70db laeq.1hr. May be permitted for a period of no more than 8 weeks to enable baffle mounds to be constructed. If a proposed application is in essence a large significant development, and noise generation is a significant issue, the county council will require the applicant to submit with his application an environmental noise statement. That statement is to be prepared in the light of current guidance on preparation of such, and will include specifically with respect to noise: • in the case of the filling of a void created by mineral extraction, details of noise during extraction of minerals from the site, if available; • details of background noise; • details of local noise-sensitive existing and proposed development; • predictions of the future noise separately for: - access traffic to the site - landfill operations - fixed industrial development on the site; • methods of proposed noise control and monitoring and liaison arrangements. WASTE POLICY 43 - TRAFFIC Planning permission will only be granted for the disposal, transfer, processing or recycling of waste which is capable of being transported to sites via rail, water or primary and distributor roads as identified in the County Council’s current transport policies and programmes (TPP) document). In determining proposals, the county council will take into account the effect of lorry traffic on local communities and residential areas. Support will be given to proposals for the transport of waste by rail or water. Where the transport of waste would require the use of local roads (as defined in the county council’s TPP) to gain access to the waste management site from the major road network, or where other roads may be unsuitable on traffic safety, engineering or environmental grounds for increased levels of heavy traffic, applicants for planning permission will be required to carry out, WGCMetals. Application ref: 6/2095-10 Site ref: CM909 14 and submit the results of, a study of the impact of heavy goods vehicle traffic on road safety and the environment. Planning permission will be granted if the traffic impact study demonstrates that the adverse impacts can be ameliorated by environmentally acceptable highway and/or other improvements to the satisfaction of the county council. All road works which would be necessary to permit waste management development would either be the subject of planning conditions requiring the works to be carried out in advance of development or subject to the applicant entering into a legal agreement with the County Council to ensure the implementation of such improvements. Where appropriate, limits on vehicle numbers will be imposed. Where acceptable works to local rural roads would enable temporary waste management development to take place, the restoration of such roads back to their original scale and appearance once waste disposal development is complete may also be required, depending on local circumstances. In determining applications for waste management facilities, the county council will take into account the effect the extra activity will have upon other users of the road system in the area, the structure of the roads, road verges, roadside trees, hedges and the adjoining environment. Conditions to prevent any soiling of the public highway may be imposed including the provision of suitably surfaced access roads, wheel cleaning equipment, and, possibly, water bowsers and sheeting to prevent dust or spillage. Welwyn Hatfield District Plan 2005 (adopted 15 April 2005) Policy EMP1 - Employment Areas The following areas of land as shown on the Proposals Map are designated as Employment Areas: EA1 Welwyn Garden City Industrial Area 149 Employment land is a very valuable resource. Policy 14 of the Hertfordshire Structure Plan Review 1991-2011 seeks to foster economic growth in existing employment areas through planned regeneration. It provides for the re-use of existing employment land and buildings for Class B uses. With regard to nonClass B uses, these will only be allowed where existing employment land and buildings are no longer required to meet future employment requirements and business and community needs. This is important in the context of the restraint arising from the location of the district within the Green Belt, which limits the amount of land available for employment. Accordingly, a cautious approach has been adopted by the Council, which generally resists uses other than those within Class B in designated Employment Areas. In the context of this cautious approach, it is important to keep employment development in balance with potential housing supply and the available WGCMetals. Application ref: 6/2095-10 Site ref: CM909 15 infrastructure. Employment development on a large scale may increase pressure for additional housing to be built within the district in order to attract an inflow of labour; there may also be circumstances where the scale of employment generated will, instead of attracting workers from the local area, attract commuters in to the district, resulting in an unsustainable increase in traffic and subsequent congestion. The approach set out in paragraph 12.19 above provides clarity for existing occupiers and potential investors and thereby facilitates continued investment and the regeneration of the older parts of the Employment Areas, through the upgrading of existing building and facilities and through redevelopment. The Council will give favourable consideration to proposals for the redevelopment of existing employment sites, in the designated Employment Areas, which would update and improve the quality of the employment stock in the district. Other Employment Generating Uses in Employment Areas Whilst the Council seeks to retain designated Employment Areas for uses within Class B, it is recognised that there is a need for some flexibility to meet the needs of uses such as tyre and exhaust centres, trade wholesalers, vehicle hire, plant hire and taxi vehicle depots, which are composite uses, combining a retail element with a predominately business, industrial or storage use, but which do not readily fit within Use Class B. Due to the planned nature of the district's two main towns, it is difficult to find suitable locations for these uses outside of the designated Employment Areas. Vehicles sales showrooms are a sui generis use and are dealt with separately in Policy EMP4. In situations where it can be clearly demonstrated that existing land or premises are no longer required to meet future employment requirements and business and community needs, the Council may grant planning permission for other, non-Class B, uses. In considering proposals for non-Class B uses in Employment Areas, the Council will also pay particular attention to the resultant employment density of the proposed development, the impact on the vitality and viability of the district's town centres, the effect on local transport infrastructure and the general impact on the environment of the area. Proposals for retail and leisure uses in the designated Employment Areas will also need to demonstrate that they accord with the sequential approach set out in Planning Policy Guidance note 6: Town Centres and Retail Developments or its successor. Policy EMP2 - Acceptable Uses in Employment Areas In the designated employment areas, proposals for development within Use Classes B1, B2 and B8 will be permitted, subject to the following criteria: (i) The proposal would not, due to the scale of employment generated, have an unacceptable impact on the demand for housing in the travel to work area; (ii) The proposal would not have an unacceptable impact on the local and/or strategic transport infrastructure; WGCMetals. Application ref: 6/2095-10 Site ref: CM909 16 (iii) The proposal would not harm the amenities of any nearby residential properties; (iv) The development would provide adequate parking, servicing and access; (v) Any retail element of the development would clearly be ancillary to the main business use. Proposals for Class B8 development should also be well located in relation to the primary road network. Proposals for any other uses in the designated employment areas should generally be resisted and will only be permitted where it can be clearly demonstrated that the existing land or premises are no longer required to meet future employment requirements and business and community needs. All such proposals will also be required to satisfy criteria (i) to (v) above and other relevant policies of the Plan relating to the use proposed. Policy R1 - Maximising the Use of Previously Developed Land In order to make the best use of land in the district, the Council will require development to take place on land which has been previously used or developed. Development will only be permitted on 'greenfield' land where it can be demonstrated that no suitable opportunities exist on previously used or developed land. WGCMetals.
