Chalgrove Airfield EbD - Thursday evening
HCA objectives for Chalgrove Airfield The Homes & Communities Agency (HCA) is the government’s housing, land and regeneration agency. The government approved the transfer of Chalgrove Airfield to the HCA, as it was deemed surplus by the Ministry of Defence. HCA is committed to deliver a new community on part of the Chalgrove Airfield site. This will include significant investment by the Agency to support areas of housing and employment growth south of Oxford.
The HCA: • Fully recognises the importance of its tenant at Chalgrove Airfield site Martin Baker Limited as an important local employer and that the release of part of the Airfield site for development must not adversely affect business continuity. • Is committed to maintaining the opportunity for aerospace businessrelated testing to operate from Chalgrove Airfield site including the re-provision of a suitable airstrip alongside its plans to deliver a new community on part of Chalgrove Airfield. • Will ensure that existing jobs are safeguarded and more employment opportunities are created in the future. • Is committed to an infrastructure first development solution for Chalgrove Airfield. • Has an extensive track record in delivering high quality sustainable communities based on exemplar place-making principles.
Chalgrove Airfield EbD - Thursday evening
Drainage - Baseline summary The airfield site is located outside areas of known flood risk. It is recognised however that parts of Chalgrove village lie within the flood zone of Chalgrove Brook. The airfield site is broadly flat, but does slope gently to north west and south west. The topography of the site creates three natural catchment areas which drain to adjacent watercourses. Two areas discharge to local watercourses to the west and north of the site before entering the Haseley Brook. The third discharges to the Chalgrove Brook, but down stream (west) of Chalgrove village. A small part of the airfield slopes towards Chalgrove and the run off currently creates some flooding issues for the village. The ground conditions have potential for the use of infiltration drainage (eg soakaways). This would be verified through intrusive testing on site.
Chalgrove Airfield EbD - Thursday evening
Ecology Baseline summary Broadleaved woodland is an important habitat, which is acknowledged through its inclusion on Section 41 of the NERC Act 2006. Every effort will be made to retain the woodland blocks in situ. In the event that this isn’t possible, a compensatory planting scheme would be agreed with the local planning authority that ensures ‘no net loss’.
The airfield and immediately adjacent habitats could support bird assemblages of local importance. Targeted breeding and wintering bird surveys will enable an assessment to value to be carried out. If important assemblages of birds are identified, suitable mitigation will be agreed with the local planning authority to ensure no net loss.
A single pond is located to the north-west of the site. Ponds can support a range of protected species. Further investigations are planned for this year.
Bats receive high levels of protection throughout the UK and many species are known to actively forage over grassland. A targeted bat activity survey would be undertaken to ascertain the presence of important flight lines or foraging areas. If large numbers of bats are recorded, suitable mitigation will be implemented to ensure no habitat fragmentation.
By far the most abundant habitat within the proposed development footprint is poor semi-improved grassland and improved grassland. Both habitats are typically poor in terms of species and are considered to be of low ecological value. Hedgerows are listed as a principal habitat. Surveys will be undertaken to ascertain whether they are meet the criteria to be considered as ‘important’ under the Hedgerow Regulations Act 1997. Important hedgerows will be retained within the development. In the event that a hedgerow cannot be retained, a compensatory planting scheme would be agreed with the local planning authority that ensures ‘no net loss’.
Chalgrove Airfield EbD - Thursday evening
Implications from today’s design session Drainage The majority of the proposed developed area would discharge using the principles and hierarchy of SUDS (Sustainable Urban Drainage Systems) to the Chalgrove Brook (down stream of the existing village). Some of the site drains to the north and would need to be piped beneath the relocated runway.
There are two potential options for treating the effluent from the proposed development.
Ponds, swales and similar features will need to be incorporated into any new development to reduce runoff at source, decrease the likelihood of flooding, whilst improving water quality and biodiversity. The aim is to restrict surface water discharge to existing greenfield runoff rates or lower where possible.
2. Provide a new on-site Sewage Treatment Works to treat effluent prior to discharging into the existing water course.
Measures would need to be put in place to prevent any run off towards Chalgrove Village. This would improve the current situation in the village.
1. Expansion of the existing Thames Water Sewage Treatment Works (to the north east of the site). Discharge to be controlled/attenuated to slow flow to the existing ditch.
Ecology Current plans include the retention of the most valuable ecological features. soft landscaping plans are being developed to result in a net gain for biodiversity.
Chalgrove Airfield EbD - Thursday evening
Landscape - Baseline summary Chalgrove Airfield lies within the Clay Vale landscape character area, between the Oxford Green Belt to the north-west and the Chilterns AONB to the south-east. The Oxfordshire Wildlife & Landscape Study states that the characteristics of the Clay Vale include “flat, lowlying landform , mixed land uses, mature trees, tree-lined streams and ditches and small to medium sized nucleated villages”. In considering landscape quality and sensitivity of the Airfields, the South Oxfordshire Landscape Assessment states (Table 3.2) that they have the following characteristics: • Scenic Quality: Low • Sense of Place: Weak • Intrusive Influences: Frequent • Other heritage values: Uncommon • Visual sensitivity: High • Sensitivity to change: Low • Management strategy: Reconstruct
Source: South Oxfordshire Landscape Assessment (SODC and Atlantic Consultants)
Page 30 of the Landscape Assessment states that the airfields are examples of land uses ‘which have disrupted the natural pattern and character of the rural landscape. Here ‘intervention which would help to reconstruct more sympathetic character and to mitigate adverse impacts on the surrounding landscape would be desirable’. Applying these criteria to the SODC Landscape Capacity methodology, we believe it is reasonable to conclude that Chalgrove Airfield has relatively low landscape value and low sensitivity to change but it does have high visual sensitivity. Applying these criteria leads us to conclude that the Airfield has high landscape capacity to accommodate change but it is important that any future design has regard to the site’s high visibility in the context of the surrounding high quality landscape.
The South Oxfordshire Landscape Assessment (below) notes that the surrounding Clay Vale landscape is predominantly ‘Undulating open vale’ and ‘Undulating semi-enclosed open vale’. Chalgrove and Benson Airfields are described separately as: • Large expanses of open ground with very little vegetation to interrupt views and an open exposed character. • Typical features of high security fences, large-scale sheds or other buildings which are out of character with their rural setting. • High intervisibility.

Chalgrove Airfield EbD - Thursday evening
Landscape - Baseline summary Chalgrove Airfield is a highly visible site. Any development will have to have regard to key views into the site, but can also take advantage of views out of the site to create a ‘sense of place’ and strong local identity. Some of these views are highlighted below.
View from the Chiltern Hills AONB towards the airfield site with Watlington in the foreground
Views towards to the Chiltern Hills AONB from within the airfield site looking east
Fox Covert and Little Holcombe Covert form a feature to the south of the site

Views towards the south western edge from Shakespeare’s Way
Chalgrove Airfield EbD - Thursday evening
Heritage - Baseline summary Thirty five heritage assets are recorded within a 1km radius of the site centre. Seventeen of these are ‘designated’. These are recognised at a national level and protected by legislation.
Rofford DMV
The remaining assets are ‘non-designated’. These are recognised at a local level and are thought to make a positive contribution to local character.
Rofford Manor
Rofford Hall
Chalgrove Airfield
The ‘designated’ assets comprise 15 listed buildings (Grade II and Grade I listed), the Chalgrove Conservation Area (designated 1992) and Rofford Manor and Hall (Grade II) both take their name from the Deserted Medieval Village (DMV) the Registered Battlefield of Chalgrove (1643). Rofford located approx 900m northwest.
A Registered Battlefield is defined as one included on Historic England’s Register of Historic Battlefields. The register identifies 46 important English battlefields, with its purpose being to offer the sites protection through the planning system, and to promote a better understanding of their significance and public enjoyment. There are 18 “non-designated” assets. These date from the prehistoric period to the 20th century and include the finding of Roman and medieval coins and the hangar on Chalgrove Airfield.
The Manor affords views across the site towards the Chilterns, but is most closely associated with the medieval landscape to the north. The Hall affords views across the west of the site, but the association with its post-medieval landscape has now largely disappeared following construction of the airfield in the 1940’s.
Chalgrove Airfield EbD - Thursday evening
Implications from today’s design session Key issues to address in any future redevelopment of Chalgrove Airfield include: • Creating stronger landscape edges to the Airfield and along the B480. • Creating a more ‘sympathetic’ character , with increased tree planting and hedgerows. • Improving views from sensitive locations. • Creating a ‘well defined’ settlement. • Creating an appropriate form of settlement (eg ‘linear’ or ‘nucleated’). • The relationship with Chalgrove Village.
The proposed alignment of the runway avoids the Registered Battlefield and avoids additional intrusive development within or in close proximity to the site. The setting of the listed Rofford Manor and Rofford Hall can be maintained by the placing of the proposed runway and possible drainage ponds to the north and the south west of the site.
Chalgrove Airfield EbD - Thursday evening
Chalgrove Village - Baseline summary The Oxford Wildlife and Landscape Study states the Clay Vale is characterised by ‘small to medium size nucleated villages’, although Chalgrove has evolved as a linear settlement. Chalgrove originally developed along the narrow stream that runs along the valley base south of the Oxford-Watlington Road, defining a linear form along the High Street. The historic core of the village is now designated as a Conservation Area, where a cluster of listed buildings focus around The Green. The SODC Conservation Area Study states that ‘modern housing impinges on the historic character throughout much of Chalgrove with much infill between many of the older buildings’. The study notes that the most important view in the Conservation Area are onto and around The Green, although the view down the High Street is also notable. The built character in Chalgrove presents a wide range of styles and is reflective of the different periods of construction. The predominant characteristics for Chalgrove are summarised in the plan and caption boxes below.
Review of historic maps identifies that historically the Oxford - Watlington route crossed through the airfield site to the north of Chalgrove. The formation of the airfield by 1943 saw this route redirected through the village until a bypass was constructed in 1967 to form the new route of the B480 around the north of the village and south of the airfield.

Chalgrove Airfield EbD - Thursday evening
Services - Baseline summary Proposals for Chalgrove Airfield will need to ensure the right community services and facilities are in place in the right locations. Certain facilities will serve residents of the new development. Other facilities, such as a secondary school can potentially serve a much wider catchment. Employment: Residents have access to a range of high quality job opportunities throughout South Oxfordshire at Science Vale and the nearby Monument Business Park. This will be supplemented through a variety of new jobs provided at and around the airfield site. Education: Oxfordshire County Council has identified a need for at least one new primary school. A second primary school may be required or alternatively an expansion to the existing village school. Significant expansion of secondary school provision is required in the area. The committed and proposed development will require at least an 800-pupil secondary school. There are a range of employment opportunities throughout South Oxfordshire. Current employment growth is planned for in Science Vale with a proposed 1,000 new jobs at Culham Science Centre. Key areas of employment growth that are proposed within Oxford City’s Core Strategy before 2026 are in southeast Oxford and include 1,450 new jobs at Oxford Business Park and 1,150 new jobs at Oxford Science Park.
Community: New community facilities will be required, including new health care provision. Shops, open space and leisure: The development should support a range of local shops and services, which complement the size of the proposed development.

Chalgrove Airfield EbD - Thursday evening
Implications from today’s design session • HCA commitment to a mixed-use community • New primary school location should complement expanded village school • Possible new secondary school could serve new and existing catchment population • Opportunities to expand employment for small businesses at Monument Business Park • Location of shops, services and community facilities to maximise population within 400 and 800m walk
• New development should protect the identity of Chalgrove village and its historic linear character. • A nucleated settlement would reflect the character of Clay Vale and provide a different settlement form to distinguish itself from the existing village.
Chalgrove Airfield EbD - Thursday evening
Local accessibility - Baseline summary It is important to establish the destinations to which people will need to be able to walk and cycle in order to facilitate those movements through design and address any barriers. There is a good selection of local facilities within the village of Chalgrove, predominantly located adjacent to High Street. These include a supermarket and Post Office, Doctor’s surgery, florist and multiple public houses. The primary school and recreation ground are located adjacent to Baronhurst Drive off High Street.
Currently there are no pedestrian footways along either side of the B480 between the junction with Monument Road and its link with High Street to the west. The link between the B480 and the Doctor’s surgery also has no pedestrian footway provided, although there is footway provided between High Street and the Doctor’s surgery. Marley Lane runs along the western boundary of Chalgrove village, which provides gated access between the B480 and routes into Chalgrove. Pedestrian facilities along this link are limited but could be upgraded if necessary. Bus service T1 currently routes along the B480, and through the village of Chalgrove. Bus stops are situated in five locations along High Street/Monument Road.
A range of employment land uses, including Monument Business Park, are located to the east of the existing airfield and are accessed via Monument Road. There are existing Public Rights of Way through Chalgrove, including one which runs parallel to the B480 (although fenced off from the B480) between Chapel Lane and Orchard Close.

Chalgrove Airfield EbD - Thursday evening
Traffic flow & speeds - Baseline summary Traffic flows and speeds will influence the design and form of access junctions and pedestrian crossing facilities on the B480. Traffic speeds along the B480 are reasonably high; average weekday speeds are typically above the 50mph speed limit. This is likely to mean that speed reduction measures on the B480 will be necessary to assist with any pedestrian crossings between the Airfield Site and Chalgrove Village. Traffic flow is relatively low for the nature of the road, typically fewer than 6 vehicles per minute. This indicates that traffic capacity on the B480 is unlikely to be a major constraint on access junction design. Traffic flow into/out of the village of Chalgrove follows a tidal pattern (AM out, PM in) and is relatively evenly split between the High Street and Monument Road links. The levels of flow on these routes are relatively low, at fewer than 300 vehicles per hour.
Vehicle flows into Monument Lane/Warpsgrove Road to the north of the B480 are also tidal, with dominant northbound flow from the B480 during the AM peak and southbound flow onto the B480 during the PM peak. Both these flows are relatively low, at fewer than 300 vehicles per hour.
Chalgrove Airfield EbD - Thursday evening
Implications from today’s design session A new route could be provided into the site from the B480 to the north west of the site, which would run through the site and rejoin the B480 to the north of the existing Chalgrove Village to the west of the allotments. This route could be fronted on both sides by housing and local facilities to create a sense of place and discourage excessive vehicle speeds whilst still providing a movement function. This potential route could effectively form the new B480 route, with the existing B480 route downgraded to reduce vehicle speeds. If implemented, this would reduce the severance effect of the B480, which carries low traffic volumes but at high speed. Thus assisting with pedestrian movements between the new development and the existing village of Chalgrove.
A strong pedestrian route could be provided between a new local centre in the development site and the existing High Street in Chalgrove. Other pedestrian routes could be enabled including to destinations such as Monument Business Parks and local Public Rights of Way such as Shakespeare Way. The siting of new local facilities in a focal point within the proposed development would maximise the proportion of existing and future residents within comfortable walking distance of day to day services. This would enhance the quality of place and reduce reliance on the private car. The existing High Street could remain of a similar character, with traffic continuing to pass by the north of Chalgrove, either on a new route through the new development, or the existing B480.
