Aston Road, Haddenham

HAD01: Aston Road, Haddenham The site as shown on the Policies Map is allocated for an assumed number of 560 dwellings. Development of this site will be supported where it: a) Accords with a comprehensive masterplan, to be submitted to and formally approved by the Council prior to the determination of any planning application, to ensure coordinated and integrated development across the whole site. b) The layout and design of development is to consider the existing underground fuel pipeline, ensuring safety and compliance with relevant standards. c) Delivers appropriate traffic calming measures along Aston Road. d) Does not prejudice the delivery of the Haddenham NESS site. e) The site is located close to the Haddenham Wastewater Treatment Works (WwTW). Development will be permitted only where it can be demonstrated that: i. The living conditions of future occupiers will not be adversely affected by odour or other emissions arising from the WwTW, informed by a proportionate Odour Impact Assessment. ii. The design, layout and scale of development will not prejudice the continued and effective operation of the WwTW, nor place unreasonable constraints on its future maintenance, operation or permitted activities. iii. Early engagement with the operator of the WwTW has been undertaken to inform site design, and mitigation measures. iv. Any necessary mitigation is incorporated through site layout, buffers, landscaping, or other design-led measures and is shown to be effective and deliverable. 6.432 The 17.44 ha site lies south of Haddenham beyond the settlement edge and is currently undeveloped countryside. Surrounding uses include business and residential areas with green space to the north, greenfield land to the east and south (including a wastewater treatment works), and a railway line with further greenfield land to the west. Access could be achieved from Aston Road (north) or Stanbridge Road (east). 6.433 The site contains two Archaeological Notification Areas (ANAs) linked to cropmarks, with a further ANA immediately north covering Haddenham’s historic core. There is high potential for prehistoric and medieval remains, including links to Aston Sandford. The site is not within a Local Historic Landscape but is bordered by locally listed features, including the medieval remains of Aston Sandford (east) and Tythrop House (south-west). While no listed buildings or TPOs lie within the site, a Conservation Area with numerous Grade I and II listed buildings adjoin the north-west boundary. Geophysical survey and trial trenching should be undertaken. 6.434 The site contributes to the rural setting of the nearby Conservation Area and supports important views to and from heritage assets. Views into the site are partially screened by tree belts and hedgerows, especially along the northern boundary and Aston Road. More open views exist from Stanbridge Road, the Public Right of Way in the north-east, and elevated viewpoints to the south-east, including the Chilterns. Development should focus on the less sensitive northern area. A heritage impact assessment should be undertaken to inform a design that respects key views and the setting of heritage assets. 6.435 The landscape is in good condition with moderate visibility and sensitivity. Guidance supports conservation and reinforcement, particularly protecting views towards the Chiltern escarpment. Key public views towards the escarpment should where possible be retained. 6.436 The nearby treatment works presents potential odour, emissions, and operational risks that could affect residential amenity and health, while also requiring protection of its ongoing function. Early engagement with the operator and design-led mitigation is recommended to address impacts and integrate constraints into the site layout.
