Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The appeal is allowed and planning permission is granted for the Installation of a solar farm comprising ground mounted solar PV panels with a generating capacity of up to 49.99MW(AC), including mounting framework, inverters, underground cabling, stock proof fence, CCTV, internal tracks and associated infrastructure, landscaping and ecological works for a temporary period of 50 years at Land to the east and west of Mareham Lane, Sleaford, North Kesteven, Lincolnshire NG34 0AW, in accordance with the terms of the application, Ref: 23/1419/FUL, subject to the conditions set out in the attached schedule. Preliminary Matters 2. The decision notice states that the Council based its decision on Revision I of the Site Block Plan. However, the addendum to the committee report discussed Revision J in some detail and confirms it was considered by Officers. Ultimately, the planning committee based its decision on Revision I. Nevertheless, Revision J has been submitted with the appeal and is the document referred to in suggested drawings condition and the submissions of both the Council and appellant. This plan shows a buffer around the ancient monument and panels removed from four archaeological areas. 3.

The appeal site is broadly split by Mareham Road into two parcels of land - the western and eastern fields. The ‘eastern field’ as defined on the site location plan submitted with the appeal includes the whole of the area between the former rail line and Mareham Road and Station Road and the woodland to the north. The site block plan (revision J) excludes a part of the eastern field from the red line area as plotted on that drawing. After seeking clarification from the Council and appellant, I have taken the appeal site to be as defined in the site location plan i.e. the whole of the eastern field including that part left out of the red line area in the site block plan. The implication being that part of the appeal site would have no panels sited within it. I have considered the proposal on this basis. 5. The Government is currently in the process of consulting on proposed amendments to the National Planning Policy Framework (the ‘Framework’). The draft revised Framework could be subject to significant amendments following the conclusion of the consultation and therefore it has little weight in my assessment of the current appeal.

Page 2 · Chunk 5 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision Instead, the extant version of the Framework has been considered. Background 6. The Council refused the application for a single reason alleging a failure to provide sufficient information to assess the effect on heritage, principally archaeology and the setting of the Scheduled Monument and Grade II listed Wayside Cross Base. The appellant has submitted additional evidence with their appeal. After reviewing this, and the responses from expert consultees, including Historic England, the Council confirmed that in its view the appellant had addressed the reason for refusal. A report was taken to the Council’s Planning Committee, and a resolution was passed to engage in the appeal on a ‘no contest’ bases. 7. Thus, it became apparent before the Inquiry was due to open that all the matters in dispute between the Council and appellant had been resolved. Indeed, both the Council and appellant are of the view that the appeal should be allowed, and planning permission granted. These parties therefore invited me to assess the proposal on the written submissions, which is what I have done as a proportionate response in the circumstances. In so doing, I have considered the main concerns of interested parties in my reasons below.

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision Reasons The effect of the proposed development on the significance of heritage assets 8. The appeal site encompasses an area that was identified as potentially including sensitive archaeology. A geophysical survey suggests that the appeal site has a long history of cultivation including medieval ridge and furrow. However, intensive post-medieval ploughing has resulted in poor preservation of earlier features. That said, the assessment identified four anomalies which could be features from the Bronze Age through to the Roman era. 9. Trial trenching was undertaken to investigate the archaeology further. All the archaeological finds were in the southeastern field, which is the same broad area as the four anomalies identified in the geophysical assessment. It has been hypothesised that the appeal site may have been occupied through the late Iron Age into the Romano British period. Indeed, as Mareham Road is suggested to be Roman in origin it is possible that a farm was established alongside it to exploit transport and trading opportunities. https://www.gov.uk/planning-inspectorate 2

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision Appeal Decision APP/R2520/W/25/3373351 10. The geophysical assessment was undertaken without a written scheme of investigation, and the trial trenching is incomplete - in part because crops were still in the ground on part of the appeal site. The cable route corridor was not included either. Nevertheless, The Heritage Trust of Lincolnshire Archaeology (HTL), who advise the Council, have stated that a scheme of archaeological investigation can be undertaken prior to the commencement of development to address any residual matters, including those areas that require further assessment and the deposition and dissemination of results. Overall, they are content with the level of information supplied so far, provided it is treated as an interim assessment. 11. On this basis HTL has not objected to the proposal provided a condition is imposed to secure the archaeological investigation. The investigation would need to include post-excavation analysis and any necessary mitigation measures. Mitigation may require a different method for routing the cables (perhaps above ground) and constructing the access tracks.

Page 3 · Chunk 8 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision It could involve preservation in situ of archaeological features and artefacts or investigation and recording prior to their removal. Preservation in situ could reduce the area available for solar panels and therefore the site layout cannot be taken as definitive. Nevertheless, the nature of the scheme allows for some flexibility. Moreover, the risk of a significant reduction in the number of panels beyond that proposed has been reduced by the appellant already excluding panels and associated works from the four areas identified in the geophysical assessment. The imposition of an archaeological condition is therefore a necessary and reasonable approach in the circumstances. 12. The Wayside Cross Base is located towards the northern end of the appeal site within the roadside verge. It is a small scheduled monument designated under the Ancient Monuments and Archaeological Areas Act 1979 and is therefore by definition of national importance. It is also Grade II listed. The feature is a rare example of a standing cross probably erected in the medieval period to mark a boundary. Only the base and shaft remain, with the cross probably removed during the iconoclastic campaign of the protestant reformation.

Page 3 · Chunk 9 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision It is possible that its immediate environs include some archaeological deposits. The cross has a high level of evidential and historic value. It also has some limited aesthetic and architectural interest. These values impart significance. The ability to experience the monument in conjunction with the former Roman road, and agricultural hinterland that was cultivated in the medieval period, better reveals its significance. 13. The appeal scheme would have a negative effect on the setting of the monument because the agricultural landscape would be industrialised for a lengthy time. To reduce the impact on the setting of the monument, a 25m landscaped buffer would be provided which, in time, would provide a degree of separation and screening between the diminutive monument and the solar farm. The overgrown foliage directly around it would also be cut back to better reveal its presence and relationship to the historic Roman road. 14. A scheduled monument restoration plan is also proposed to include repointing an open join and other necessary repairs.

The appeal scheme can broadly be split into three sections with two areas of panels on the eastern side of Mareham Lane and one to the west. The section to the west is positioned around 250m north of a historic farmstead called Thorns Farm. The Farmhouse and Farm Buildings are independently Grade II listed. 16. The Farmhouse is a fine example of mid-19th Century polite domestic architecture. It has well balanced elevations with some ornate details including the chimneys, sash windows, dentillated cornice and entrance porch with pediment and fanlight. The barns were constructed around the same time as the farmhouse and are also finished in a mellow red brick. Although simpler in appearance they exhibit some ornamentation and a rustic charm. The farm complex is very attractive and therefore has a high degree of aesthetic and architectural value which is heightened by the pleasant and remote rural setting. The farmhouse and barns were probably constructed as part of a ‘model farm’ by the landowners. The complex therefore has evidential and historic value and significance as a repository of building traditions and agricultural practices from the 19th Century.

Page 4 · Chunk 13 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The ability to experience these values is aided by the agricultural character of the setting. 17. The appeal scheme would result in the industrialisation of a large area of farmland to the north and northeast of the listed buildings through the extensive installation of panels, fencing and ancillary infrastructure. This would erode the rural agricultural setting of the farmstead and thus harm the way their significance and value is experienced. The impact would be temporary, but 50 years is nevertheless a very long time, being generational in extent. As such, the ‘temporary’ nature of the proposal carries limited weight as mitigation. 18. Nevertheless, the intervisibility between the installation and the farmstead would be significantly softened by existing planting and would diminish further as the proposed landscaping matures, especially on account of the flat landscape. The distance between the listed buildings and the solar farm is also notable. Consequently, the latter would not be a prominent background feature when experiencing the significance of the listed buildings from the lane immediately to their south.

Page 4 · Chunk 14 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision As such, the harm to the significance of the listed buildings would be modest, being at the low end of ‘less than substantial’ within the meaning of the National Planning Policy Framework (the ‘Framework’). 19. Paragraph 215 of the Framework states that any less than substantial harm to a designated heritage asset should be weighed against the public benefits of a proposal. This ‘heritage balance’ is encapsulated within Policy S57 of the Central Lincolnshire Local Plan 2018-2040 (CLLP). In calibrating the heritage balance, the Framework states that designated heritage assets are an irreplaceable resource that should be conserved for existing and future generations. Accordingly, great weight is given to an asset’s conservation. Conservation in this context means sustaining, and thus not harming, an assets significance. This is synonymous with the considerable importance and weight that must be given to the statutory duty to pay special regard to the desirability of preserving a listed building or its setting (s66(1) of The Planning (Listed Buildings and Conservation Areas) Act 1990). 20. In this case, the energy generated by the appeal scheme would meet the needs of around 15,000 households.

Concerns have been raised that the appellant’s analysis has not factored in emissions related to the construction of the panels, transporting them from abroad to the site or the loss of energy during transmission to the substation. However, a substantive analysis is not before me which demonstrates that the net carbon savings would not be significant or would be at such a diminished level that I should not apply the significant weight indicated in national policy. 21. Added to this, the construction phase would result in notable economic benefits and there would be a significant uplift in biodiversity due to measures such as planting hedges, trees and sowing wildflower meadows. The scheme would also deliver modest community benefits in the form of a picnic site and a space for community beekeeping. Overall, the benefits would accrue weight of a high order and would, in this instance, be of sufficient force to collectively outweigh the low level of less than substantial harm that would occur to both designated heritage assets.

Page 5 · Chunk 18 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision It follows that the effect on heritage in isolation does not justify dismissing the appeal. The proposal would therefore adhere to Policies S14, S53, and S57 of the CLLP, which are consistent with the relevant national policy in the Framework. The effect on the character and appearance of the area 22. The appeal site is located within the Central Plateau Landscape Character Type (LCT) as defined in the North Kesteven Landscape Character Assessment. It is typical of the key characteristics of this LCT being generally arable, isolated and rural with neatly trimmed boundary hedges that have been left to grow out a little. There are mature trees around the site boundary and pockets of woodland. To the northeast of the appeal site is a pleasant area comprised of small meadows next to mature woodland. The landscape is generally flat which enables long views in some locations but in others hedges and woodland provide effective screens that limit the vistas across the landscape. 23. The solar farm would have an industrial character and would be of a substantial size. The proposal would therefore harmfully erode the rural, relatively tranquil character of the appeal site and its immediate environs.

Page 5 · Chunk 19 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The effect would be temporary, but 50 years is a very long time. As such, the magnitude of change would still be of a high order. The proposal would have a significant adverse impact on landscape character as it would be a long standing and alien industrial feature in a pleasant rural landscape. 24. The appellant’s Landscape and Visual Impact Assessment (LVIA) has considered the effect of the scheme with reference to a zone of theoretical visibility (ZTV). This considered the height of the development relative to the topography. The ZTV is extensive given the flat landform. However, this is a worst-case scenario that assumes bare earth. In reality, there are hedges, woods and buildings that provide screening. The ZTV is nevertheless useful in identifying representative viewpoints (VPs) from which to consider the visual impacts of the scheme. The Council has not disputed the methodology in the LVIA. 25. Of the 12 VPs identified, the authors of the LVIA conclude that the effect on 9 of them would generally be ‘minor adverse’ in wintertime at Year 1 falling to ‘negligible’ to ‘minor’ in the summer.

The Council has accepted these findings and so do I after visiting the site. Importantly, minor effects were identified from nearby footpaths (including VP 5, 6, 7, 8 and 12). In many views the panels and associated infrastructure would be dark, distant features set below the tree line. This would assist in reducing the visual prominence. As boundary hedging matures and thickens, the panels would be well screened, even in winter months. Setting the panels in from the boundaries of the site and splitting them up into three groups divided by woodland and part of a field would also assist in breaking up the massing of the panels so they would not be seen as one extensive feature. 26. The panels in the eastern field would be more visible in views from the immediately adjoining roads (VP 1 and 9). However, the existing and proposed hedging and buffers would provide some softening, and the receptors would likely be motorists travelling at speed and concentrating on the road in front of them. That said, the effect would be short but not fleeting given the size of the scheme. The LVIA reasonably concludes that there would be a moderate effect from these locations. 27.

Page 6 · Chunk 23 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision There would be quite a stark view of the panels from Mareham Lane in a position to the east of VP2 on the approach to the site. Here, the existing hedging in the southwestern corner of the eastern field is kept low to provide visibility at the junction of Mareham Lane and Station Road. The panels would be directly in front of motorists moving north towards Sleaford. However, the plans show the panels set back into the site behind a landscaped buffer. There is nothing to suggest a small copse could not be planted in the southwestern corner of the eastern field to provide a screen. The trees may have a shading effect on some of the nearest panels, but such an impact would be reasonable given the need for mitigation. 28. Drawing this all together, the appeal scheme would have a significant impact on landscape character, but the visual impact would be localised with only a minor effect beyond the site boundaries. Overall, the proposal would have a moderate residual adverse impact on the character and appearance of the area. 29. Policy S1 of the CLLP is supportive in principle of renewable energy schemes in the countryside. Consequently, some impact is to be expected.

Page 6 · Chunk 24 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision Indeed, Policy S14 of the CLLP places a presumption in favour of proposals for ground-based photovoltaics and associated infrastructure unless there would be clear and demonstrable significant harm arising. As such, the policy sanctions some harm up to a threshold. The moderate localised effect would not cross this threshold and therefore the proposal would adhere to Policy S14. Loss of agricultural land and effect on food production 30. The appellant has undertaken a review of previously developed land within a 3km search area of the Sleaford substation into which the scheme would connect. I have seen nothing of substance to suggest this is not a reasonable search area when considering the cost and practicalities of achieving a grid connection point. Three sizable sites were identified but they are allocated for residential development or have planning permission for housing. Disaggregating the appeal scheme onto the roof tops of existing buildings would incorporate significant practical and logistical difficulties to the extent that this is not a realistic proposition. I have not been directed to any other parcels of non-agricultural land that would be suitable for accommodating the appeal scheme.

The application was accompanied by the results of soil testing that indicates the appeal site overall falls within Grade 3(b) for soil quality. This is outside the category of best and most versatile agricultural land (Grades 1, 2 and 3a). The Council’s agricultural land consultants reviewed this information and has not disputed the methodology or findings. Natural England have not raised concerns either. As such, the proposal would not result in the loss of best or most versatile agricultural land and the subsequent effect on food production this would have. It therefore adheres to the Framework, which states that where significant development of agricultural land is demonstrated to be necessary, as is the case here, then areas of poorer quality land should be preferred to those of higher quality. Moreover, the appeal site would be out of intensive cultivation for 50 years which could allow time for the soil to improve. In conclusion, the scheme’s effect on agricultural land would adhere to Policies S14 and S67 of the CLLP. The effect on the living conditions of the occupants of nearby properties 32.

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The proposal would result in the noise generating infrastructure and plant being located alongside Mareham Lane or within the middle of the western field and thus away from the nearest residential properties. The Council do not dispute the appellant’s proposition that the noise emitting infrastructure would operate quietly, typically producing 50-70dB at 1m. As noise decreases over distance, it is anticipated that any noise would be inaudible at the nearest residential properties. To provide further reassurance, the Council and appellant have recommended a condition that noise levels should not exceed a stated level at the boundaries of the residential properties. This would be a sensible precaution. 33. Concerns have been raised about the impacts of construction, but I share the view of the Council and appellant that this can be mitigated through a condition requiring a construction management plan (CMP). This would control hours of operation alongside other measures. It is anticipated that construction would take around six weeks and involve around 245 deliveries of which around half would be from HGVs, therefore amounting to about 8 HGV deliveries a day.

Page 7 · Chunk 29 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision This would be noticeable, but not excessive and any movements would be during the day. It is unlikely an enforceable condition could be imposed requiring a specific route to be followed for deliveries as this would require controls being placed on the use of the public highway. However, a Construction Traffic Management Plan has been submitted with the appeal and this includes a route which can be encouraged. The appellant would aim for all construction traffic to enter the site from Mareham Lane and the A52. This would result in HGVs passing as few residential properties as possible. The proposal would not harm residential amenity when accounting for the short duration of the construction period and the mitigation measures. 34. The nearest residential properties to the appeal site adjoin the southeastern corner. The panels would be modest in height at 3.2m, but the scheme overall would have an industrial character and would be of a considerable size. Old Station House is only around 10m from the site boundary. There is what appears to be a commercial yard to the north and amenity space to the east. The solar farm would be to the west separated by a track and hedge.

This buffer would also soften the effect on the occupants of The Gatehouse to the south of Old Station House. In conclusion, the effect on living conditions would not be at odds with Policy S14 of the CLLP. The effect on protected species and wildlife 35. Initial scoping indicated that the appeal site is in a landscape with several features and sites that can support biodiversity. Indeed, within 5km there are three statutory sites and Local Wildlife Sites adjacent to it. There are also ponds, drains/water courses, mature trees, hedges and field margins in the vicinity. These features can support several protected and priority species such as bats, breeding birds, great crested newts, badgers and common toads. 36. As such, a suite of biodiversity surveys accompanied the application. In general, these surveys concluded that the arable fields in which the panels and development would take place are of low value to biodiversity whereas the periphery of the fields, where there are margins and hedges, is of more value.

Page 8 · Chunk 33 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The scheme has been designed to respond to these findings by retaining the areas of biodiversity value and setting the development in from the site boundaries behind planted buffers. This approach would avoid adverse impacts on protected species. It would also ensure there would be adequate space between the appeal scheme and the adjoining woodland. The buffer would also provide an increase in the size of suitable habitat available to many species. I have already explained that there would be a generous measurable net gain to biodiversity. Impacts on wildlife during construction, especially great crested newts and common toads, would be addressed through a construction environmental management plan. 37. The exception to the above is ground nesting birds such as skylarks, which nest in arable fields. Surveys identified 5 skylark territories which would be lost to the development. The appellant has suggested that a condition could be imposed to require a skylark mitigation and compensation scheme, which would likely result in a financial contribution towards a scheme proposed by Lincolnshire Wildlife Trust. However, the ‘scheme’ would ultimately need to be secured through a planning obligation.

Page 8 · Chunk 34 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The Planning Practice Guide is clear that a condition requiring a party to enter into a planning obligation should only be imposed in exceptional circumstances and when the heads of terms are agreed. In this case, there are no exceptional circumstances and heads of terms, such as the extent of the financial contribution, the location of the mitigation and details of ongoing management of the skylark plots by the relevant landowner, are undefined. 38. Instead, the condition can be amended to secure skylark mitigation and management in the form of 5 skylark plots on site. There would be ample space to do this as parts of the appeal site would remain undeveloped due to archaeology. There is also an area included in the red line of the appeal site but excluded from the developed area as shown on the Site Block Plan (between Fields 2 and 3 as defined in the geophysical assessment), which could include the plots. In conclusion, the appeal scheme would not harm protected species, would result in a biodiversity net gain and adhere to Policies S14, S60 and S61 of the CLLP. Other Matters 39.

This is a road where traffic moves quickly and therefore deer could pose a risk to highway safety. Indeed, during my site visit I observed a large herd of deer in the fields and woodland to the northeast of the appeal site. As proposed, deer fencing would run for a long way along the eastern side of Mareham Road and would obstruct the route between the woodland on the western side of the road from that to the northeast of the appeal site. However, there is nothing of substance before me to suggest the middle part of the site (between Fields 2 and 3) needs to be fenced as it would not include any solar panels. Accordingly, this area could be left unfenced (with gates at either end of the access track) so that deer can pass through the site. Suggested Condition 3 requires fencing details to be submitted for approval, which would be a means of addressing this issue. 40. Otherwise, the Local Highway Authority (LHA) has not raised any concerns regarding the effect of the proposed development on highway safety.

Page 9 · Chunk 38 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision Indeed, the LHA found that the proposed access would operate safely and there would be no harmful (or severe) effects on the road network when the scheme is considered individually or cumulatively with other operational solar farms nearby. Any works to Mareham lane to facilitate the cable route would need to be approved by the Local Highway Authority. There is no substantive or technical evidence before me that would justify departing from the independent expert view of the LHA. 41. The application was accompanied by a glint and glare assessment which concludes that there would be no adverse impacts in this regard. This has been reviewed by several consultees, and no objections have been raised. Similarly, Lincolnshire Fire and Rescue have been consulted and raised no concerns regarding fire safety and the Council’s Environmental Health Team are satisfied there would be no pollution. The Council has not raised any objections with respect to flooding and drainage. I have no substantive reason to come to a different view on any of these matters.

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision Concerns have been raised regarding the potential for a future battery energy storage system, but this is not part of the scheme before me and therefore I have not considered this point further. 42. The appellant and Council have considered cumulative effects given the presence of other solar farms near to the appeal site. Given the lack of intervisibility and the way the proposal would be broken up into three areas with intervening landscaping, the cumulative impact would be modest. There is another large solar farm proposed nearby which is currently under consideration, but it is not for me to comment on its merits. Instead, it would be for the Council to consider the cumulative effects of that scheme in the first instance. Similarly, I understand that a reservoir is being planned for the area. Again, it is not for me to comment on the merits of that project, which is still in the formative stages. No doubt cumulative impacts would form part of the assessment of the reservoir in due course. 43. National Policy Statements (NPS) EN-1 and EN-3 have recently been updated. EN-3 explains that it covers nationally significant solar photovoltaic schemes of greater than 100MW.

Some of the conditions require details to be resolved prior to commencement of development since the matters they relate require resolution before development start or are so fundamental to the development permitted that it would have been otherwise necessary to refuse the whole permission. 45. In addition to the standard commencement condition, it is necessary in the interests of certainty to impose a condition requiring implementation in accordance with a suite of approved plans and limiting the period of the permission. For similar reasons, and in the interests of the character and appearance of the area, biodiversity and highway safety, it is necessary to secure details of CCTV Columns, fencing and gates and external lighting. I have amended Condition 3 to also refer to solar panels because some alterations to the layout may be required following the completion of the archaeological investigations. To safeguard the environment, it is necessary to secure appropriate decommissioning. In the interests of highway safety, biodiversity and living conditions, it is necessary to manage construction.

Page 10 · Chunk 43 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision To safeguard cultural heritage, it is necessary to secure a scheme of archaeological investigation, mitigation and recording. 46. To secure mitigation and benefits, it is necessary to impose a condition requiring a scheduled monument restoration plan and details of the picnic area and community beehive scheme. To protect skylarks, it is necessary to secure the provision and management of 5 plots on site. To secure biodiversity net gain it is necessary to require a habitat management and monitoring plan. In the interests of biodiversity and visual amenity it is necessary to secure tree protection measures, an arboricultural method statement, protection of retained trees, a landscaping scheme and a landscape and ecological management plan. To protect living condition, it is necessary to secure a landscaped buffer with the residential properties adjacent to the southeast corner of the appeal site. For a similar reason, it is necessary to control noise levels when measured at a residential boundary. 47. The Council has sought a financial contribution towards monitoring due to the extent and complexity of the measures required to secure a biodiversity net gain.

Page 10 · Chunk 44 Appeal Decision

Land to the east and west of Mareham Lane, Sleaford, North Kesteven, NG34 0AW — North Kesteven District Council — Appeal Decision The appellant has provided a planning obligation in the form of a unilateral undertaking to secure this. Due to the importance of biodiversity net gain to the acceptability of the scheme, a monitoring fee in this instance is necessary, directly related to the development and fair and reasonable. The planning obligation can therefore be taken into account. Conclusion 48. The appeal scheme would adhere to the development plan and there are no other considerations which outweigh this finding. Accordingly, for the reasons given, the appeal has been allowed.

Main issues and findings

Heritage impact
Against appellant
¶8-14

The proposal would have a negative effect on the setting of the Scheduled Monument and Grade II listed Wayside Cross Base, but the proposed buffer and restoration plan would mitigate this impact.

Character and appearance
Against appellant
¶22-28

The solar farm would erode the rural, relatively tranquil character of the appeal site and its immediate environs, but the visual impact would be localised and the proposal would adhere to Policy S14 of the CLLP.

Living conditions
Against appellant
¶32-34

The proposal would have a moderate impact on the living conditions of the occupants of nearby properties, but the effect could be reduced to an acceptable level with a more generous buffer and the imposition of conditions.

Flood risk
Neutral
¶41

The Council has not raised any objections with respect to flooding and drainage.

Ecology and biodiversity
For appellant
¶35-38

The proposal would result in a biodiversity net gain, and the appeal scheme would not harm protected species.

Highway safety
Neutral
¶40-41

The Local Highway Authority has not raised any concerns regarding the effect of the proposed development on highway safety.
