It is anticipated that it may be necessary to provide further information about the potential of the site from field observations in order to draw up a scheme to mitigate the impact of development on any below-ground archaeological deposits if necessary. Such a scheme could be implemented by an appropriately worded condition attached to any consent gained.

The project was commissioned by Mr Colin Viret, of Millwood Designer Homes Limited, Bordyke End East Street, Tonbridge, Kent, TN9 1HA and comprises the first stage of a process to determine the presence/absence, extent, character, quality and date of any archaeological remains which may be affected by redevelopment of the area. Site description, location and geology The site is located on land adjoining Tilsmore Lodge, Mount Pleasant, Heathfield, East Sussex, and is centred on NGR TQ 5720 2155 (Fig. 2). The site represents an irregular area of approximately 1.4ha. Today this area is on the edge of a large wood (Tilsmore Wood) and is mainly grassland but with a tree belt along the western edge and numerous trees marking internal boundaries. The proposal site was visited on 27th January 2016 (Pls 1-6). No archaeological finds or features were identified over the course of this visit. The proposal site occupies a spur between two small stream valley and slopes from an elevation of approximately 146m above Ordnance Datum in the west to 130m AOD in the east. According to the British Geological Survey (BGS 1979) the underlying geology consists of Ashdown Beds - Sandstone, Siltstone and Mudstone. Planning background and development proposals Planning consent is being sought from Wealden District Council for a residential development (Fig. 1). No details are to hand at time of writing. The Department for Communities and Local Government’s National Planning Policy Framework (NPPF 2012) sets out the framework within which local planning authorities should consider the importance of conserving, or enhancing, aspects of the historic environment, within the planning process. It requires an applicant for planning consent to provide, as part of any application, sufficient information to enable the local planning authority to assess the significance of any heritage assets that may be affected by the proposal. The Historic Environment is defined (NPPF 2012, 52) as: 1 ‘All aspects of the environment resulting from the interaction between people and places through time, including all surviving physical remains of past human activity, whether visible, buried or submerged, and landscaped and planted or managed flora.’ Paragraphs 128 and 129 state that ‘128. In determining applications, local planning authorities should require an applicant to describe the significance of any heritage assets affected, including any contribution made by their setting. The level of detail should be proportionate to the assets’ importance and no more than is sufficient to understand the potential impact of the proposal on their significance. As a minimum the relevant historic environment record should have been consulted and the heritage assets assessed using appropriate expertise where necessary. Where a site on which development is proposed includes or has the potential to include heritage assets with archaeological interest, local planning authorities should require developers to submit an appropriate desk-based assessment and, where necessary, a field evaluation. ‘129. Local planning authorities should identify and assess the particular significance of any heritage asset that may be affected by a proposal (including by development affecting the setting of a heritage asset) taking account of the available evidence and any necessary expertise. They should take this assessment into account when considering the impact of a proposal on a heritage asset, to avoid or minimise conflict between the heritage asset’s conservation and any aspect of the proposal.’ A ‘heritage asset’ is defined (NPPF 2012, 52) as ‘A building, monument, site, place, area or landscape identified as having a degree of significance meriting consideration in planning decisions, because of its heritage interest. Heritage asset includes designated heritage assets and assets identified by the local planning authority (including local listing).’ ‘Designated heritage asset’ includes (NPPF 2012, 51) any ‘World Heritage Site, Scheduled Monument, Listed Building, Protected Wreck Site, Registered Park and Garden, Registered Battlefield or Conservation Area designated under the relevant legislation.’ ‘Archaeological interest’ is glossed (NPPF 2012, 50) as follows: ‘There will be archaeological interest in a heritage asset if it holds, or potentially may hold, evidence of past human activity worthy of expert investigation at some point. Heritage assets with archaeological interest are the primary source of evidence about the substance and evolution of places, and of the people and cultures that made them.’ Specific guidance on assessing significance and the impact of the proposal is contained in paragraphs 131 to 135: ‘131. In determining planning applications, local planning authorities should take account of: • the desirability of sustaining and enhancing the significance of heritage assets and putting them to viable uses consistent with their conservation; • the positive contribution that conservation of heritage assets can make to sustainable communities including their economic vitality; and • the desirability of new development making a positive contribution to local character and distinctiveness. ‘132. When considering the impact of a proposed development on the significance of a designated heritage asset, great weight should be given to the asset’s conservation. The more important the asset, the greater the weight should be. Significance can be harmed or lost through alteration or destruction of the heritage asset or development within its setting. As heritage assets are irreplaceable, any harm or loss should require clear and convincing justification. Substantial harm to or loss of a grade II listed building, park or garden should be exceptional. Substantial harm to or loss of designated heritage assets of the highest significance, notably scheduled monuments, 2 protected wreck sites, battlefields, grade I and II* listed buildings, grade I and II* registered parks and gardens, and World Heritage Sites, should be wholly exceptional. ‘133. Where a proposed development will lead to substantial harm to or total loss of significance of a designated heritage asset, local planning authorities should refuse consent, unless it can be demonstrated that the substantial harm or loss is necessary to achieve substantial public benefits that outweigh that harm or loss, or all of the following apply: • the nature of the heritage asset prevents all reasonable uses of the site; and • no viable use of the heritage asset itself can be found in the medium term through appropriate marketing that will enable its conservation; and • conservation by grant-funding or some form of charitable or public ownership is demonstrably not possible; and • the harm or loss is outweighed by the benefit of bringing the site back into use. ‘134. Where a development proposal will lead to less than substantial harm to the significance of a designated heritage asset, this harm should be weighed against the public benefits of the proposal, including securing its optimum viable use. ‘135. The effect of an application on the significance of a non-designated heritage asset should be taken into account in determining the application. In weighing applications that affect directly or indirectly non designated heritage assets, a balanced judgement will be required having regard to the scale of any harm or loss and the significance of the heritage asset. Paragraph 139 recognises that
