North Norfolk District Council Conservation, Design and Landscape MEMORANDUM To: Geoff Lyon, Team Leader, Enforcement & Special Cases Ref: PF/13/0960 From: Cathy Batchelar, Landscape Officer Date: Sep 30th 2013 Re: Installation of 3.6mw solar development & associated infrastructure, Pond Farm, Bodham The proposed site is within a large arable field situated 2km south east of Bodham village and 800m south of West Beckham. The site is situated on the high plateau making up Cromer Ridge which forms one of the highest points in North Norfolk. The field slopes downwards from south to north with the highest point in the south-west at 96m AOD and the lowest in the northwest corner at 89m. From a landscape perspective, the main areas for consideration arising from a development of this nature are the effect on the landscape character and visual impact. A Landscape & Visual Impact Assessment (dated 1st August 2013) (LVIA) has been carried out by The Landscape Partnership as part of the submitted information. I am satisfied that it has been prepared in accordance with the latest accepted methodology (Guidelines for Landscape & Visual Assessment, 3rd edition, 2013, Landscape Institute & IEMA). Landscape Impact The site lies centrally within the Tributary Farmland landscape character Type as defined in the North Norfolk Landscape Character Assessment (SPD June 2009). The broad characteristics of this Type are an open character with long uninterrupted views, a sense of height gained from the extensive high domed plateau, arable land use and rolling topography punctuated by woodland and hedge field boundaries. The site is located within the TF3 sub-area where dispersed settlement and loss of field boundaries are typical features. The LVIA concludes that the development would have a Moderate Adverse Significance of Effect on TF3 in Year 1, reduced to Minor Beneficial in Year 10. I would agree that this would be the case once the landscape mitigation has established and field boundaries are restored. The effect on the whole Tributary Farmland Type is assessed as Minor Adverse in Year 1 reducing over time to No Change and on the neighbouring Wooded with Parkland (WP5) Landscape Type as No Change and this is a fair assessment. The change of land use will undoubtedly have a bearing on the landscape character. The introduction of multiple built structures set in uniform rows, together with the inverter stations, security fencing and CCTV cameras make up a large scale development that will not be in keeping with the pastoral nature of this traditional rural landscape. Although forming a large geometric element in the landscape, the development is however relatively low level with the tallest elements being 3m. In this regard substantial boundary landscape proposals have the potential to form mitigation that is effective in reducing the negative visual and landscape effects. The LVIA states in 12.2 that within the local vicinity of the site the small copses and hedge boundaries together with the local landform significantly limit views of the site and the influence 1 that the development would have on the local landscape character. I would concur with this assessment and the conclusion that the landscape has a high to moderate capacity to accommodate this type of development, subject to appropriate location and mitigation to ensure successful integration into the existing landscape. The field is currently used for mixed production of cereals/sugar beet and oil seed rape grown in rotation. The Genatec Planning Statement classifies the agricultural land as Grade 3 and this has subsequently been qualified in more detail by the submission of an Agricultural Land, Classification Report, dated 17/9/2013 by David Will. This report concludes that the land is mainly Grade 3b with some parts being Grade 4. In accordance with the NPPF, the land does not therefore constitute ‘the best and most versatile agricultural land’. While the loss of land for agricultural production for 25 years is an issue for consideration, this must be balanced with the need for farm diversification to support rural economies, along with the fact that the land can be readily reverted at the end of the period of operation. Visual Impact Given the high and open nature of the site the Zone of Visual Influence (ZVI), as defined in Figure 7 of the Genatec LVIA Figures, is relatively contained by virtue of the surrounding undulating topography and vegetation cover. The visual impact would be greatest from Osier Lane along the northern boundary of the site which is part of the Sustrans Regional Cycle Route 30. This is confirmed by the LVIA assessment at Viewpoints 4, 5, 6 & 7 where a Major Adverse Significance of Effect is predicted in Year 1. Due to the aspect of the field it is the support frame at the back of the panels that will be most visible from Osier Lane. However with the proposed mitigation designed specifically to reduce this effect and to reinforce traditional field boundaries I agree that this effect would, for the most part, be considerably reduced by Year 10. Mitigation Due to the relatively low level of the development, the proposed mitigation will in time be effective in forming a partial screen of the solar array. The planting proposals are appropriate in terms of design and species selection and will integrate and reinforce the local landscape character in line with the recommendations contained in the North Norfolk Landscape Character Assessment. However, there is one area that I believe requires more substantial planting than that proposed. This is along the north eastern boundary where there is an isolated decline in the landform. The proposed new hedge will not screen the views of the panels rising up the field for residents of the properties to the North East of the site. In this area another woodland copse such as Planting Note 2 on the Site Layout Plan should be included to provide more height and become a more effective screen for these receptors. This can be agreed through submission of an amended Site Layout Plan or incorporated into a Landscape condition as part of planning consent. No proposal is included to enrich the soil under the panels with a species rich grassland mix. This is recommended in the Ecology Report as a measure to enhance the biodiversity of the site and should be included. An Ecological Buffer Zone is referred to in the LVIA text (7.1) but there is no detail of what this may consist of or how it will be achieved. This should form a component of more detailed landscape specifications. Landscape Management The submitted Landscape Management Plan is appropriate apart from the lack of certainty with regard to the management of the grassed pasture and buffer zone. More detail is required. 2 Security Notwithstanding the security details submitted I am of the opinion that there may be alternative security measures available that are more appropriate for this rural setting The proposed 2.2m high security steel post and wire fencing around the entire boundary along with the 15 CCTV cameras mounted on 3.5m poles will be prominent elements of the scheme that jar with the rural landscape context and are more familiar in an urban setting. A more sensitive security solution such as timber post and wire with integrated CCTV, such as used in similar schemes in the district would be more suitable. This can be achieved by way of a condition imposed on security elements of the scheme. The proposed access off New Road is an appropriate location. Planting proposals are suitable following construction but should include for removal of the work compound area and reinstatement of the ground conditions. Impact on Heritage Assets There are no listed buildings, scheduled ancient monuments, conservation areas or registered historic landscapes that would be adversely affected by this development. The Historic Environment Service has been consulted with regard to archaeological impact. Impact on Ecology The Ecological Report prepared by Wild Frontier Ecology, dated March 2013 has been carried out to accepted guidelines and comprised a Desk Study and Phase One Habitat Survey. The Survey concluded that the development would have ‘no significant impacts on valued ecological interests’ and in my opinion this is a fair assessment. The mitigation measures put forward in Section 6 of the Report are proportionate and in line with the landscape proposals. Cumulative Assessment The LVIA did not include assessment of the potential cumulative effect of a recently approved 10 mw solar farm at East Beckham covering 25ha (PF/13/0772). The site lies 1.8km north of the Pond Farm development. By virtue of the rolling landform and vegetation I am of the opinion that there will be no inter-visibility between the two sites and in this regard the cumulative effect will be negligible. However, there will undoubtedly be some perceived change in the local landscape character which should be a consideration. The LVIA has considered the cumulative effect of the development with Planning App PF/11/0983, a single wind turbine which is currently subject to a Statutory Challenge. This is sited within the same field as the solar array and although very different in nature, when viewed together will cause a significant change in the local landscape character. The combined visibility (i.e. when both developments can be viewed simultaneously) will be most severe from Osier Lane to the north of the site of the solar array. The landscape mitigation proposed for both developments will reduce this effect, but only to a small extent and not as much as is suggested in Section 11 and Section 12.9 – 12.13 of the LVIA. Conclusion Although large in scale and introducing new elements into the rural landscape, this development, by virtue of the proposed landscape mitigation combined with natural screening afforded by surrounding landform and existing vegetation, will not have a significant effect on the landscape character. The proposal is therefore acceptable under Core Strategy Policy EN 2. 3 Conditions Should this application go forward for planning consent, conditions with regard to the following elements of the scheme should be included: landscape specifications, timing of planting, replacement planting, landscape management, security measures, lighting, ecological mitigation measures.
