NORTH WALSHAM - PF/12/1332 - Erection of building comprising eight flats and one shop; 4 Market Street for MAZdev Ltd Minor Development - Target Date: 11 March 2013 Case Officer: Mrs M Moore Full Planning Permission CONSTRAINTS Primary Shopping Area Conservation Area Listed Building Grade II Town Centre RELEVANT PLANNING HISTORY PLA/20090917 PF - Extension and Conversion to Provide Six Flats, Three Retail Units and Replacement Public Conveniences Approved 30/11/2009 PLA/20090918 LA - Alterations and Extension to Provide Six Flats, Three Retail Units and Replacement Toilets Approved 30/11/2009 PLA/20060855 LA - Partial demolition and rebuilding conversion to three flats Approved 09/11/2006 PLA/20060854 PF - Partial demolition and rebuilding to provide three flats Approved 09/11/2006 THE APPLICATION The proposal seeks to demolish the remaining structure on site and replace with a three and four storey development comprising 8 flats and a ground floor shop, bin storage and cycle parking areas. The site area measures approximately 282sq.m. The scheme proposes brick and render elevations and red clay pantiled roofs and timber windows and doors. Amended plans have been submitted to introduce render to the elevations, to include cycle parking, to address Building Control issues and to ensure compatibility between the elevations and floor plans. An associated application for Conservation Area Consent for the demolition of the existing structure on this site (LE/12/1333) will be determined under delegated powers. Development Committee 1 30 May 2013 REASONS FOR REFERRAL TO COMMITTEE At the request of Councillor A. Moore having regard to the following planning issues: The design, height and impact of the development. TOWN COUNCIL Support REPRESENTATIONS 10 representations have been received, comprising 8 objections and 2 comments. Objections (summarised) Height of proposed building and impact upon views gained from Market Street of North Walsham landmark of St. Nicholas Church, one of the most significant vistas; Building far taller than surrounding buildings, not in keeping with general architecture or existing adjacent (listed) buildings; Mass of proposed building; Not enough outdoor amenity space to provide basic amenities, no provision for clothes drying, car parking. Assuming the two and three bed flats are designed for families, there is no provision for outside secure play areas; Would be better to have no building or a proportionate and sympathetic renewal within Conservation Area; Out of scale with other historic buildings close by. Would dwarf surrounding buildings; Proposals would dramatically change the street scene within Conservation Area. The roofline has not changed since the construction of the existing building; Gross overdevelopment of site; Developer bought property knowing it was a Listed Building in a Conservation Area. Must have known it was uneconomically viable to repair it in its original form as are many Listed Buildings. After partially demolishing the building he has managed to get it de-listed; This latest proposal would seem to be a further attack on planning process and whole purpose for Listed Building Consent and of Conservation Areas; Loss of light to neighbouring properties; Concern if development would be higher than existing; Concerns regarding privacy of neighbours and occupiers of development; Contravenes Policy EN8 which provides essential safeguards for Conservation Areas; Proposed development would deprive forever future generations of joy and excitement as they enter the town from Cromer of an amazing and iconic vista of roofs of varying heights, different pitches and textures that frame the broken church tower behind; Over the years, residents of North Walsham have not been blessed with good long-term planning decisions that have become hallmark for development in Holt and nearby Aylsham so effectively. Proposal has limited architectural merit and would simply not just be tolerated by the residents of those more concerned communities. Would further blight church precinct in ways not dissimilar to ravages of 1960s schemes. Now commonly recognised that these earlier schemes both in the church precinct and along Vicarage Street and the car park beyond were disastrous steps taken in haste and without due consideration for historic importance and context of the town. This application is in many ways little different; Design unimaginative, poor quality and lacks sensitivity in scale and materials; Development Committee 2 30 May 2013 Scheme predicated on need to maximise financial return and arguments made in Design and Access Statement to justify this are lame and not properly validated; Development would have significant and degrading impact on overall historic and architectural interest of Conservation Area and should not be permitted; The Design and Access Statement makes little effort to justify retention of buildings in the context of their significance to overall character and appearance of Conservation Area; Decisions to demolish purely on financial grounds- this is what Conservation Area Status designed to prevent; No attempt to indicate that a less intensive use of site has been considered seriously; this would have reduced overall cost significantly and consequently the need to over-develop site. Sheer size and scale and notably height; this is the major issue with this application; Little effort to research previous buildings on lavatory block site; Some evidence that previous building may have been destabilised intentionally as a way to reduce cost of any subsequent renovation. Decision to demolish building under these circumstances serves only to vindicate bad practice and sets a dire precedent for future development within what remains of Conservation Area. Neither Town nor District Council should be seen to endorse such practice. Not clear whether English Heritage were made aware of full circumstances in reaching their decision; Proposals of scale and design that are at variance with design and character of other individual buildings within Conservation Area. Arguments made in Design and Access Statement of enhancing setting of church following the manner of buildings around Market place are profoundly misleading and inaccurate; Design insensitive and lacks historical integrity. Proposals show a contempt for the site and other buildings within Conservation Area; Design and Access Statement states that 'the new building facing the church is now four storeys high rather than three, the ridgeline is almost the same'misleading. Highest elevation of buildings to be demolished is lower than parapet on adjacent 1830s building facing the Market Place. New building has a complete extra storey added. Unnecessary had the development been less intensive and planners had taken more seriously their obligations to protect buildings within Conservation Area; Design and Access Statement states that 'world economic recession has also made it necessary to reassess the financial balance of the scheme'- simplistic and misleading. There are unconsidered alternatives. Building would be overengineered and over-intensive use of site; Development would be towering and intrusive presence as walk down Loke to church; Monotone brick features and pseudo Georgian windows and dormers would be alien and unwelcome in setting of Historical Church Precinct and Grade I Listed Building; Despite ravages of 1960s scheme, elements of church precinct remain intact and are unspoiled. Area still has atmosphere and charm. Insertion of building of this size and crude design will further degrade what remains of an important historical element of Conservation Area; Poor planning decisions have served only to impoverish and degrade historic townscape- long term impact on character of town and may explain lack of customer footfall and struggle that specialist local retailers have to un-established businesses in face of increasing competition from growth of supermarkets. Examples given including demolition in Church precinct, Vicarage Street, area where car park is situated to north of church, demolition of 18C/19th C Granary buildings to north of church and beyond car park, Old Windmill site traditional Development Committee 3 30 May 2013 cottages; Suggests positive recent examples- sheltered housing on Hall Road, Church End House end of Church Precinct. Comments: Requires assurance that new build would not impact on light coming into neighbouring flat and no windows directly looking into flat. If there would be a loss of light, would they receive compensation? Where would neighbour refuse bins be stored (currently located in shopping precinct due to the building site) be stored? Listed Building and any redevelopment works must be carried out sympathetically and in keeping with adjoining properties; Height should not exceed existing roof line and certainly not as high that it obstructs view from Market Street/Cromer Road of the Church tower. CONSULTATIONS County Council (Highways) - Given the town centre location and the fact that there is no likelihood of vehicular access to this development, the Highway Authority does not consider the lack of dedicated vehicular parking to be of concern. Cycle parking, however, would be of benefit and recommends that some provision for this is made on the site. Recommends conditions in relation to provision and retention of cycle parking to be provided and that no part of the proposed structure is to overhang or encroach upon highway land. Building Control - Concerns raised: It appears from the plans that the unprotected areas on the boundaries are excessive; A smoke vent will need to be provided to the top of the common stair; It would appear that the current new build requirements for access have not been met as no provision has been made for a lift. If no lift is to be provided then the common stair would need to be suitable for ambulant access, and this may require additional space. English Heritage - No objection. Recommends conditions regarding materials, detailing and workmanship of all elevations. Conservation, Design and Landscape Manager (Conservation and Design) Without rehearsing the difficult circumstances which surround the recent history of this site, this scheme is essentially a reworked version of that previously approved. This said, with the condition of the site having deteriorated through the passage of time, the need for development has become even more acute. With the building having also been recently delisted by English Heritage, Conservation & Design can now concentrate purely on the impact of the proposals on the setting of the adjacent listed buildings and upon the character and appearance of the wider conservation area. In this respect, the site is flanked on both sides by Grade II Listed Buildings when viewed from Market Street. These helped create the characteristic rhythm of the three diminishing gables which framed this important view within the designated area. The submitted scheme simply looks to reinstate this historic street scene by replacing the demolished structure on a like-for-like basis. Therefore, at its western end, the impact upon the neighbouring heritage assets would be entirely neutral (if Development Committee 4 30 May 2013 you consider the former position), and wholly positive (if you consider the current situation). Further back into the site, the new build elements stack up as the land rises towards the east. Again this echoes the traditional building pattern and is considered appropriate for the context. Where this scheme principally differs from its approved predecessor is that it no longer provides for integral public toilets. Instead these have been relocated in the interests of freeing up accommodation to make the scheme a more viable proposition. Associated with this, the tallest three-storey block has been jacked up slightly to provide a more workable layout. This would undoubtedly have some impact upon the existing views of the Grade I Listed Church which currently looms above the site when approaching from the west. However, as this revised proposal would only be some 300mm taller than that approved, and with only the very top of the Church tower currently visible, the level of harm would not be sufficient to warrant an objection. Rather, it is considered that the overall gains to be had in terms of reinstating the townscape far outweigh this concern. On the east side, the proposals continue to address the Churchyard as before. With the exception of the recent St Nicholas Court, this is unusual with all of the other buildings historically turning their backs onto the space. As previously, however, Conservation and Design believe that the gains to be had from presenting an animated façade more than outweigh any form and character arguments. Elsewhere, the design has been extensively discussed prior to the submission of this application. As such, the elevations presented give no grounds for concern at this stage – ultimately the devil will be in the detail. The only thing worth mentioning is that the absence of a southern elevation makes it rather difficult to get a proper feel for this forth side of the scheme. Whilst recognising the difficulty in accurately depicting this façade, and acknowledging that most of it would not be readily visible from public vantage points, there is clearly a degree of guesswork involved without it. Closing comments - In summary, this is a site which has blighted the town centre for several years and which is long overdue redevelopment. By approving this revised scheme, it is hoped that things can finally move forward. Recommends conditions relating to samples of bricks and tiles to be submitted, areas of brickwork to be laid in a Flemish bond using a mortar which contains no grey ordinary Portland Cement, sections through the joinery, shopfronts doorcases and first floor bay window to be submitted, details of the verges, eaves, window cills and arches to be submitted, rainwater goods to be black painted metal and colour finish for the joinery to be submitted. Environmental Health - recommends conditions requiring scheme for kitchen extractor system for the new shop to be submitted and the addition of informative notes in relation to extract/ventilation and demolition. Sustainability Co-ordinator- recommends condition requiring the implementation of measures to minimise energy use, minimise resource use and adapt the building to withstand future climate change and requirement for dwellings to meet Code Level 3, Code for Sustainable Homes. Historic Environment Service - recommends conditions required in relation to written scheme of investigation, including recording, prior to any demolition/development taking place. Development Committee 5 30 May 2013 Anglian Water - Comments awaited. HUMAN RIGHTS IMPLICATIONS It is considered that the proposed development may raise issues relevant to Article 8: The Right to respect for private and family life. Article 1 of the First Protocol: The right to peaceful enjoyment of possessions. Having considered the likely impact on an individual's Human Rights, and the general interest of the public, approval of this application as recommended is considered to be justified, proportionate and in accordance with planning law. CRIME AND DISORDER ACT 1998 - SECTION 17 The application raises no significant crime and disorder issues.

Design, height and scale of development 3. Impact on historic environment, including Conservation Area and setting of Listed Buildings 4. Impact on neighbouring amenities 5. Highway/parking issues APPRAISAL Principle of development The site is located within the development boundary of North Walsham and the Town Centre and Primary Shopping Area, where there is no objection to the principle of erecting a shop and flats, subject to satisfactory compliance with other relevant Core Strategy policies. Development Committee 6 30 May 2013 Permission was granted under reference PF/20060854 for the partial demolition and rebuilding of 4 Market Street to provide three flats. Permission was then granted under reference PF/20090917 to extend and convert the building to provide six flats, three retail units and replacement public conveniences. Design, height and scale of development The site holds a very prominent position within the Town Centre and the North Walsham Conservation Area. The site currently detracts from the character and appearance of this part of the town, with its poor condition and partly demolished buildings. 4 Market Place itself has recently been formally de-listed. The Committee will note that Conservation, Design and Landscape Manager has commented that the site is flanked on both sides by Grade II Listed Buildings when viewed from Market Street. These helped create the characteristic rhythm of the three diminishing gables which framed this important view within the designated area. The submitted scheme looks to reinstate this historic street scene by replacing the demolished structure on a like-for-like basis. Therefore, subject to the imposition of conditions regarding materials and detailing, it is considered that the erection of the building would help to reinforce the strong sense of enclosure on Market Street and would broadly respect surrounding buildings in terms of design. Excluding the chimneys, at its highest point the proposed development would measure approximately 12.5m in height, not significantly higher than the previously approved scheme. Although the proposed building would be higher than the existing structure, it is not considered that this is an overriding issue as there is a variety of other building sizes within the town centre and given what has been previously approved. The flats would meet the Council's amenity criteria in terms of habitable floor space and external bin areas would be provided. Whilst outdoor amenity areas would not be provided, in this case, it is recognised that the site lies within a designated Town Centre where many dwellings in the area do not have outside amenity space. As such, lack of amenity space is not considered to be a justifiable reason for refusal in this case. Impact on historic environment, including Conservation Area and setting of Listed Buildings The partly demolished buildings currently detract from the Conservation Area. Although taller than the existing building and previously approved scheme, it is considered that, subject to careful consideration in terms of materials and detailing, the proposed development would enhance the character and appearance of the Conservation Area. In terms of potential impact on St. Nicholas Church, the Committee will note that the Conservation, Design and Landscape Manager has commented that, in a change to the previously approved scheme, the tallest three-storey block would be jacked up slightly to provide a more workable layout. This would undoubtedly have some impact upon the existing views of the Grade I Listed Church which currently looms above the site when approaching from the west. However, as this revised proposal would only be some 300mm taller than that which has been approved, and with only the very top of the Church tower currently visible, the level of harm would not be Development Committee 7 30 May 2013 sufficient to warrant an objection. Rather, it is considered that the overall gains to be had in terms of reinstating the townscape far outweigh this concern. In the light of this advice, the scheme is considered to have acceptable impacts on the historic environment. Impact on neighbouring amenities In respect of the potential for loss of amenity, overlooking and loss of daylight, concern has been expressed by the owner of an adjacent flat. It is recognised that the erection of the eight flats and one shop on this fairly narrow site would inevitably result in a significant shortfall in the Basic Amenity Criteria recommendations. The development would be very closely flanked by neighbouring buildings to the north and south. Both of these buildings contain flats with living accommodation windows which would face the proposed development. The concerned neighbour's second floor flat to the south has facing windows serving a hall and it would appear that these windows would face towards a hall window and a blank section of wall/roof on the new development. In this case, the largest shortfall in terms of the Basic Amenity Criteria would be between the hall window facing towards a blank section of wall/roof, where the Basic Amenity Criteria recommends a distance of 2.5m and the development would only provide circa 1.2m. Under the previously approved scheme, these neighbouring windows appeared to face towards a roof and towards/over a wall at a similar distance from the neighbouring building. To the north, permission was granted under reference PF/12/0800 for alterations to allow the conversion of the first floor to a self-contained flat. At the time of writing this report, it did not appear that this development had been commenced. If implemented, the flat would have four facing windows; two serving a kitchen and two serving a bedroom. If converted, the largest shortfall in terms of the Basic Amenity Criteria would be between one of the bedrooms and a bedroom on the new development, where the distance would be circa 3.1m and the Basic Amenity Criteria recommend 15m, resulting in a shortfall of approximately 11.9m. Under the previously approved scheme, these neighbouring windows would have faced walls and windows, including a bedroom and living room window, again at a similar distance from the neighbouring building. Inevitably, the proposed development would result in some loss of amenity to these neighbouring flats, but consideration should be given to what has previously been approved on the site, the fact that the site is within a town centre where buildings are generally close knit and the need to re-develop and enhance the current site. In terms of privacy, at this stage it is difficult to be precise in terms of how the proposed windows would relate to neighbouring windows. The Committee will note that, should the development be approved, Condition number 11 would require a scheme to be submitted to and approved in writing by the Local Planning Authority detailing which windows and rooflights would be fitted with obscure glazing. This would require the submission of a plan from the applicant's agent detailing the relationship between existing neighbouring windows and the proposed development. Highway/parking issues Given the town centre location and the fact that there is no likelihood of vehicular access to the development, the Committee will note that County Council (Highways) have no objection to the proposed development, subject to the provision of cycle parking spaces. Development Committee 8 30 May 2013 Furthermore, Policy CT 6 of the Development Plan allows for reduced parking provision in order to facilitate development which would enhance the character of Conservation Areas in town centres. Summary The principle of development is considered to be acceptable in this location and although the proposed scheme does not strictly comply with Development Plan policy in respect of the Basic Amenity Criteria in relation to neighbouring properties, in this case, given the prominent position of this site and given previous approvals, it is considered that the potential benefits of reinstating the townscape and bringing the site back into beneficial use outweigh these concerns.

NORTH WALSHAM - PF/13/0417 - Removal of Condition 3 of planning permission reference: 11/0212 (requirement for construction of attenuation pond); Davenports Magic Kingdom, Cromer Road for Davenports Magic Kingdom Major Development - Target Date: 03 June 2013 Case Officer: Mr G Linder Full Planning Permission CONSTRAINTS Employment Area Flood risk RELEVANT PLANNING HISTORY 11/0212 PF - External cladding and use of industrial unit for D2 (entertainment centre) comprising theatre/cinema, museum, cafe, shop, research centre/archive and ancillary workshop Approved 30/10/2012 12/0871 PF - Formation of attenuation pond Approved 14/9/2012 THE APPLICATION Planning permission for the re-cladding and use of the former industrial unit for D2 (entertainment centre) granted in October 2012, included Condition 3 which required the construction of a second attenuation pond on third party land at The Old Stables (Bradmore Farm) Aylsham Road, North Walsham. This was required in order to accept the discharge of surface water from the Cromer Road site and help prevent potential flooding at Bradmore Farm. The condition also stated that the entertainment centre should not be brought into use until the attenuation pond had been constructed. The current application seeks the removal of Condition 3, which would allow the entertainment centre to open without the need for construction of the second attenuation pond. REASONS FOR REFERRAL TO COMMITTEE At the request of the Head of Development Management, given the requirement to balance the issues of off site surface water management and the economic benefits of the entertainment centre. Development Committee 13 30 May 2013 TOWN COUNCIL Wish to see the business succeed but also recognised the concerns expressed by local residents. They therefore suggest that a legally binding clause should be approved to allow the Magic Kingdom to open on 25 May 2013, to allow for the District Council to close the business down if the condition is not met within an agreed length of time. The Town Council resolved that:(a) In view of the information received, the Town Council objects to the removal of Condition 3 but suggests that the business is allowed to open. (b) The District Council be asked to impose a legally binding clause that the attenuation pond is completed within a specific period of time or the District Council will have no alternative but to close the business down until such time as the pond is completed. REPRESENTATIONS Three letters of objection from residents of Bradmore Farm which raise the following concerns (summarised). 1. The existing pond was never built to the original specifications to contain the expected amount of water. 2. The amount of water coming into the pond has increased over the years and can no longer cope with the current levels. 3. There have been a number of instances of flooding at Bradmore Farm as a result of the attenuation pond overflowing, the most serious being in June 2001, which caused extensive flooding to the dwellings. In addition, there have been more recent instances the latest being in March 2013. 4. If the flow restrictor diverting water to the attenuation swale fails during heavy rain, in excess of 121 cubic metres of water would be discharged into the existing attenuation pond. 5. The Magic Kingdom should not open until there is proper investment in a storm drainage system in the Cromer Road or the second attenuation reservoir is constructed. 6. We are sceptical that the measures suggested by the Magic Kingdom would adequately protect the dwellings around Bradmore Farm from flooding. 7. The District Council gave residents of Bradmore Farm assurances that if they granted permission for the Magic Kingdom and any other development, conditions would be imposed preventing them being brought into use until the attenuation pond, approved under planning permission 12/0871, was constructed and linked to the surface water drainage system. 8. If the lifting of the planning condition is approved we will hold the Council, Magic Kingdom and Citygate Developments accountable, responsible and liable for any damage caused by future flooding to our property. CONSULTATIONS Environment Agency - Original comments - In the absence of an acceptable Flood Risk Assessment (FRA) currently object to the removal of Condition 3 for the following reasons: The submitted FRA fails to consider the effect of a range of rainfall events including extreme events on the existing surface water drainage system and whether it could cause flooding to people and property. The Surface Water Drainage Statement by Canham Consulting dated March 2013 shows that the rates of surface water (out)falling into the surface water system that drains into the attenuation basin to the south has been reduced compared to the situation that existed in 2001. This is due to half the former Crane Fruehauf Factory Development Committee 14 30 May 2013 being demolished and a proportion of which left un-surfaced, which reduces the impermeable area draining into the sewer from 5.13 hectares to 4.31 hectares. It is also stated in the FRA that the rates and volumes of surface water draining to the attenuation pond from the 0.67 hectare impermeable area of the Magic Kingdom development would be reduced due to the installation of a flow control device limiting the surface water to the current 1 in 1 year outfall rate of 59 l/s. The attenuated surface water is to be stored upstream in an attenuation swale which has been sized to contain the volume of surface water generated in the 1 in 30 year rainfall event which is stated as being 121m³. The plans state that in the 1 in 100 year rainfall event including climate change an additional 50m³ of surface water will be stored above ground in the car park. The modelling of the attenuation swale should be submitted to demonstrate that it has been correctly sized. It is stated in the FRA that the proposed attenuation swale will reduce the volume of water discharging from the site as it will allow the surface water to infiltrate into the silty sandy stratum below until the surface water can discharge from the site via the flow control device. However without infiltration testing to determine the infiltration rate on the site it is not known what volume of water will be able to infiltrate through the swale and therefore whether this will make much of reduction in the volumes of the site and entering the attenuation pond. We understand that soil types in the area are not conducive to infiltration so infiltration testing should be undertaken to determine whether it will be possible to use infiltration. If infiltration is feasible on the site then the water from the site should be drained using solely infiltration without a positive outfall, in accordance with the priority given to infiltration drainage in Part H of the Building Regulations. Although the above measures may provide some surface water drainage improvements, we are aware that historically the surface water drainage provision for the site has always been inadequate. The attenuation basin to the south was undersized for the original Crane Fruehauf development as it was built to a smaller size than what was designed, and further developments have taken place on the site over the years which have also drained into the undersized basin and so exacerbated the situation. This has led to the attenuation basin flooding on numerous occasions. The condition on the Magic Kingdom planning permission (ref: 11/0212) requiring the construction of a second attenuation basin to the south of the site was to ensure the satisfactory drainage of the site and prevent off-site flooding. The construction of a second basin would allow a much greater volume of surface water to be stored, and so reduce the risk of the attenuation basin flooding. The FRA has not detailed whether the capacity of the existing attenuation basin is sufficient to accept the proposed reduced flows from the entire 4.31 hectare site, so the resulting flood risk is not known. Rather than comparing the proposed surface water drainage flows to the situation in 2001, the FRA should instead be assessing the proposed surface water scheme in comparison to the benefits offered through the construction of the second basin, as, although the proposed development may offer some benefits compared to the situation in 2001, it is likely that it would provide significantly less improvement than what could be achieved through the construction of a second basin, which is what was requested and conditioned by the Local Planning Authority, and what this application seeks to remove. The FRA should address this issue. Development Committee 15 30 May 2013 Also we understand that the Crane Fruehauf site was granted an 80 year long lease to discharge the surface water to the attenuation pond. This was granted in 1969, so only has 36 years left to run. The lifetime of the proposed Magic Kingdom development is assumed to be longer than 36 years, so the FRA should consider what will happen, and how the surface water will be managed, after this point in time. The long-term viability of the drainage strategy for the whole site is questionable due to this issue. Further comments (following recent stakeholder meeting) - No objection to the variation of Condition 3 which would allow the entertainment centre to open on a temporary basis for twelve months without the need to provide the second attenuation reservoir. However the condition should be varied to also ensure that the second attenuation reservoir will be brought forward, as this has implication for the development of the remainder of the site. King's Lynn Internal Drainage Board – Original comments - Objection on the grounds that the Norfolk Rivers Internal Drainage Board (and its predecessors the Upper Bure IDB) have always taken the view that the receiving watercourse, Skeyton Beck, is at capacity due to the restriction of several culverts downstream. Hence the requirement for attenuation as the site developed. The history of the development of the drainage to this site is complex as it was constructed and modified over several decades and its operation is still, to some degree, uncertain. Therefore, it is the view of IDB that the attenuation pond should be constructed as originally proposed before any further work is carried out on the site to ensure drainage integrity and reduce flood risk. Further comments (following recent stakeholder meeting) - No objection to the variation of Condition 3 which would allow the entertainment centre to open on a temporary basis for twelve months without the need to provide the second attenuation reservoir. Norfolk County Council Flood & Water Management – Original comments Objection on the grounds that the existing surface water lagoon outfall for the site has caused flooding of the downstream property due to a capacity problem. The requirement for an additional lagoon to deal with the flows from the whole of the site is necessary for the flood protection of the properties at The Old Stables, Aylsham Road and to deal with the flood risk at the development site. There is an additional concern that the lease for the existing outfall has only about 30 years remaining. Further comments awaited following recent stakeholder meeting. Environmental Health – The Environmental Protection Officer has made the following comments:The condition was originally imposed in order to protect downstream properties from the risk of flooding from an undersized attenuation pond. From the information provided it is possible to ascertain that the surface water discharge rate from the application site has been restricted to 59 l/s, with an overflow storage swale to temporarily hold any flows greater than 59 l/s. This flow rate is better than what was previously discharged when the site operated as a factory. Development Committee 16 30 May 2013 Additionally, the site has also seen a reduction in the non-permeable area on site, further reducing the flows downstream and subsequent flood risk. I am aware that the Environment Agency has objected to the application on the grounds that some of the information submitted is not up to current day standards, although they have agreed that surface water flows have been reduced. In addition, I am aware that other objections have also been received concerning flood risk to the associated downstream attenuation pond. At a meeting which took place between all relevant stakeholders on Friday 17 May, clarification was provided on actual flood risk issues. Although there have been instances of localised flooding to the downstream pond over a number of years, there has only been one internal flooding of property in 2001 reported. At this point, as lead drainage officer for Environmental Health, I am reminded that locally North Walsham as a whole had a number of properties flooded in 2008 due to a significant downpour causing flash flooding, but that there is no evidence to suggest that this caused any significant effect on the downstream attenuation pond. I am also aware that according to the Met Office, April 2012 was the wettest April since records began in 1910, but again no evidence suggests that this had any significant effect on the downstream attenuation pond serving the former General Trailers site. Although the information provided does potentially support the removal of Condition 3, given my localised flooding knowledge of North Walsham, I would be unhappy to recommend removal of the condition at this stage, but instead suggest a formal monitoring period of one year to ensure that the physical barriers installed actually reduce downstream flood risk. This time period would also allow the parties involved further time to finalise terms and formally agree the construction of the second attenuation pond, which if not done is likely to prevent further development to the application site and surrounding land. This deferred time period is also seen as acceptable by the Environment Agency, Norfolk County Council flood team and the IDB, whom were represented at the stakeholder meeting on 17 May 2013. Anglian Water – Have indicated that this is outside their jurisdiction HUMAN RIGHTS IMPLICATIONS It is considered that the proposed development may raise issues relevant to Article 8: The Right to respect for private and family life. Article 1 of the First Protocol: The right to peaceful enjoyment of possessions. Having considered the likely impact on an individual's Human Rights, and the general interest of the public, approval of this application as recommended is considered to be justified, proportionate and in accordance with planning law. CRIME AND DISORDER ACT 1998 - SECTION 17 The application raises no significant crime and disorder issues. POLICIES North Norfolk Core Strategy (Adopted September 2008): Policy SS 1: Spatial Strategy for North Norfolk (specifies the settlement hierarchy and distribution of development in the District). Policy EN 10: Flood risk (prevents inappropriate development in flood risk areas). Development Committee 17 30 May 2013 MAIN ISSUES FOR CONSIDERATION 1. Risk of offsite flooding. 2. Economic benefits of the business. APPRAISAL The site is located within the Development Boundary for North Walsham, a Principal Settlement, as defined by the North Norfolk Local Development Framework Core Strategy and is designated as an Employment Area, whilst the site of the proposed attenuation pond is within the Countryside Policy Area. Policy EN10 is relevant to the consideration of this application and states that a site-specific Flood Risk Assessment which takes account of future climate change must be submitted with appropriate planning applications. In addition appropriate surface water drainage arrangements for dealing with surface water run-off from new development will be required. The use of Sustainable Drainage Systems will be the preference unless, following an adequate assessment, soil conditions and / or engineering feasibility dictates otherwise. Background To give the application some historical context, when the former Crane Fruehauf factory was built in the late 1960s, which consisted of one building and paint store, surface water from the site was initially disposed of on site. However, as a result of on-site flooding planning permission was granted for the construction of an attenuation reservoir on land 330 metres to the south, immediately to the north of The Old Stables (Bradmore Farm). It was intended that the attenuation reservoir which was to be created by enlarging an existing drainage pond, would have an area of approximately 1 acre (0.4ha) and be some 4.5 metres in depth, with surface water discharge from the factory site being via a 450 millimetre diameter pipe. In turn, in order to prevent the attenuation reservoir overflowing a 220 millimetres diameter pipe fed into Skeyton Beck to the south side of the Aylsham Road. However indications are that the final depth of the reservoir was only 2.5 metres. Following the construction of the attenuation reservoir in 1969, the Crane Fruehauf site saw significant development throughout the 1970s, with a number of new buildings being constructed, and impermeable surfaces laid. In addition, the Wall Engineering site was developed which involved the surfacing over of a football pitch. As a result of this development the reservoir, which takes surface water from both the former Crane Fruehauf and Wall Engineering sites, has flooded on a number of occasions, the most serious being in 2001 when dwellings at Bradmore Farm flooded. In March 2002 the then owners of the Crane Fruehauf site, the East of England Development Agency, undertook works to clean out the attenuation pond in order to increase capacity. However, this does not appear to have alleviated the problem as further flooding has occurred, the most recent being in March of this year. Furthermore, the King's Lynn Internal Drainage Board has taken the view that the receiving watercourse, Skeyton Beck, is at capacity due to the restriction of several culverts downstream, and they would not allow an increase in discharge rates from the attenuation pond. The current owners of the site, Citygate Developments, have permission to re-clad 70,000 sq. feet of buildings on the site without any conditions relating to the discharge of surface water from the site. At the time when the application for the entertainment centre was under consideration, ref 11/0212, concerns were raised by the owners of properties at Bradmore Farm regarding potential flooding. Following discussions with the applicant, Davenports Magic Kingdom, Citygate Developments and the owner of The Old Stables, it was agreed that the long term solution would be to construct a second attenuation reservoir adjacent to the first, on land within the Development Committee 18 30 May 2013 ownership of The Old Stables. As a result, in order to facilitate the redevelopment of the site and encourage economic growth and job creation, and at the same time protect the interests of residents of the Bradmore Farm, the application for the entertainment centre was approved subject to Condition 3. A subsequent planning application for the attenuation reservoir was approved under delegated powers in September 2012, ref 12/0871, before determination of the entertainment centre application. Since that time discussions have continued between Citygate Developments and the owner of The Old Stables regarding the terms of the lease for the attenuation reservoir, the construction of which is unlikely to commence until agreement is reached. In the meantime, Citygate Developments have agreed the terms of the lease in respect of the entertainment centre with Davenports Magic Kingdom and works are well advanced on site, with a suggested opening date of 25 May 2013. Given the delay in agreeing the terms of the lease for the attenuation pond, Davenports Magic Kingdom have commissioned a civil engineering firm to design a scheme which reduces surface water peak run-off from the development for all storm events up to and including the 1:100 year probability storm, which includes a 30% consideration for climate change. As a result, the scheme proposes that a flow control device be installed in order to restrict flow to the 450 millimetres outfall pipe and that surface water held back by the flow restriction would surcharge and be contained within a rectangular attenuation swale, sized at 121.3m2 to the southern boundary adjacent to the Cromer Road. This swale has been constructed on site. Flood Risk Issues In considering the removal of Condition 3 of planning approval 11/0212 the principal consideration has to be whether the on-site surface water drainage strategy measures suggested by the applicant's civil engineers are adequate to prevent on and off-site flooding. In their original consultation response the Environment Agency suggested that, although the proposed flood risk measures may offer some benefits compared to the situation in 2001, it is likely that it would provide significantly less improvement than what could be achieved through the construction of a second basin. The King's Lynn Internal Drainage Board and Norfolk County Council Flood & Water Management originally suggested that the attenuation pond should be constructed as originally proposed and that Skeyton Beck is at capacity due to the restriction of several culverts downstream. The Council’s Environmental Protection Officer has indicated that from the information provided it is possible to ascertain that the surface water discharge rate from the application site has been restricted to 59 l/s, with an overflow storage swale to temporarily hold any flows greater than 59 l/s. This flow rate is better than what was previously discharged when the site operated as a factory. Additionally, the site has also seen a reduction in the non-permeable area on site, further reducing the flows downstream and subsequent flood risk. However, whilst the evidence available would tend to support removal of the Condition 3 the Environmental Protection Officer has indicated that due to his local knowledge of flooding in North Walsham, he would not wish to see the condition removed at this stage. Instead he suggests that the condition be varied so as to allow the entertainment centre to open on a temporary basis for twelve months, without the need to provide the attenuation pond, which would allow the situation to be monitored in order to assess if the physical barriers installed reduce downstream flood risk. This time period it is suggested would also allow the parties involved further time to finalise terms and formally agree Development Committee 19 30 May 2013 the construction of the second attenuation pond, which if not done is likely to prevent further development to the application site or surrounding land. The proposition to vary rather than remove the condition at this stage was discussed at the meeting of stakeholders on 17 May 2013. The King's Lynn Internal Drainage Board and Environment Agency have since confirmed that they have no objection to the variation of Condition 3 which would allow the entertainment centre to open on a temporary basis for twelve months without the need to provide the second attenuation reservoir. However the Environment Agency have suggested that varying the condition should also seek to ensure that the second attenuation reservoir will be brought forward, as this has implication for the development of the remainder of the site. The comments from Norfolk County Council Flood & Water Management will be reported orally to the Committee. Economic Issues The issues raised in respect of flood risk need to be balanced against the economic benefits of the entertainment centre, which would result in job creation and would contribute to the vitality and viability of the area and tourism. Refusal to remove or alternately vary the condition at this stage would mean that if the entertainment centre were to open as planned, the applicant would be in breach of the planning permission. Alternatively, delaying the opening until such a time that satisfactory onsite attenuation proposals are agreed or the off-site attenuation pond constructed could have significant financial implications for the applicant. This in turn may jeopardise the employment opportunities associated with the development. Other Issues The Committee will also note that if the Condition 3 is removed, local residents have indicated that they would hold the Council, Magic Kingdom and Citygate Developments accountable, responsible and liable for any damage to their properties caused by future flooding. The Committee will need to give due concern to the flood risk issues as there is a duty of care on the Council to ensure that development proposals do not result in increased on or of off-site flood risk. Conclusion In view of the recommendation of the Council's Environmental Protection Officer, and the support of other consultees who attended the meeting of stakeholders on 17 May 2013, it is considered that the best solution would be to allow the entertainment centre to open on a temporary basis for up to twelve months without the need to provide the second attenuation reservoir. This time scale would allow the physical barriers which have been installed on site to be monitored in order to ascertain if they have reduced downstream flood risk. In addition, it would allow time for the various parties to finalise the terms of the lease with a view to facilitating construction of the second attenuation reservoir. In the event that either the monitoring data gave rise to concerns or that the current measures had not limited off-site flooding to an acceptable degree, it would be open to the Committe to re-assess the position upon the submission of a further planning application in twelve months' time. Subject to receipt of the confirmation of the acceptability of a temporary permission from Norfolk County Council Flood & Water Management it is considered that this course of action would meet the objectives of Development Plan policy. Development Committee 20 30 May 2013 RECOMMENDATION: Delegated approval, subject to the further comments of the outstanding consultee, that Condition 3 of planning approval 11/0212 be varied to allow the entertainment centre to open on a temporary basis for twelve months without the need to provide the second attenuation reservoir. Also, that during this period the on-site flood risk reduction measures be monitored, including the installation of a flow rate metre on the outfall pipe, to establish whether the physical barriers which have been installed reduced downstream flood risk.
