News and Updates
In the second of our series of updates, the following is our response to the Inspector's question regarding the site capacity and housing density afforded by the Bourn Airfield site. This was included in our submission to the Inspector on 16 February. [If you would like to download a copy of the full submission, see below].
iii Does the area of land identified on Inset I of the Policies Map provide sufficient capacity to achieve the quantum of development associated with the new village?
StopBAD's original submission in October 2013 questioned the site’s ability to accommodate the 3,500 houses to be built. We pointed out that the council made significant mistakes in their calculation of the site’s capacity.
Questions concerning the site’s capacity are not new. In 1992 when Bourn Airfield was being considered as a potential site for the new settlement of Cambourne, the Planning Inspector, Mr T Kemann-Lane, submitted a report in which he drew particular attention to the “generally small and cramped nature of the site”. He observed “the Bourn Airfield proposal does lack sufficient room within its boundaries to give adequate separation (from Highfields Caldecote)”. Similarly, he thought the proposal (for only 3,000 dwellings, rather than the currently-proposed 3,500) “would produce a tight development”. This was prior to the building of Cambourne, and Highfields was less than half its present size. In addition, the A428 was not a dual carriageway in 1992, which has also reduced the size of the Bourn Airfield site by 10 ha.

Figure 5: Overview of StopBAD's original analysis
The updated land yield allocated to residential parcels (93.82 ha.) by Rummey Design (see Figure 4) on behalf of Countryside Properties comes close to StopBAD's estimated figure from our 2013 Submission of 85 ha (Figure 5). However, the yield of 93.82 ha. comes at the expense of the employment land on the Tallent site and the loss of the access spur on the North East on the site. The subsuming of these areas into the MDA means that the proposed new settlement is effectively conjoined to Caldecote Highfields. Clearly, there are now insufficient distances to achieve an effective buffer zone and visual separation between Upper Cambourne, Bourn Airfield and Caldecote Highfields.
In addition, building 3,500 houses on an area of 93.82 hectares produces a housing density of 37 dwellings per hectare (dph). A density of 37 dph is well in excess of the densities in the original Cambourne Masterplan, and closer to urban than rural density levels.
