The Spatial Framework Plan (Fig.22) contained in the draft SPD illustrates residential development in close proximity to the existing Employment area which is to be retained.

This employment area includes the site which DB Group currently operate from. The operations and processes which take place on site include the following:
* Sand grading - filtering sand to provide different levels of fineness;
* Production of additives used in concrete mixes - blending of powders from silo storage;
* Warehousing - receipt and dispatch of goods either manufactured or purchased off site for resale.

These uses, in combination, amount to a B2 General Industrial use. The blending and grading process undertaken on site generates external noise, particularly in respect of the extraction system used to reduce material spillage and particles in the air. The site is also serviced by an average of 2 incoming and 3 outgoing HGV movements a day.

The draft SPD states that "The overarching framework for Bourn Airfield new village is summarised below by theme, and spatially illustrated in the Spatial Framework Plan opposite."

As this Spatial Framework Plan will guide development coming forward within Bourn Airfield New Village it is essential that the Spatial Framework Plan takes full account of DB Group's existing operations and will not hamper future expansion plans. This will require particular consideration being given to adequate distance separation from noise sources, site and building layout / orientation, provision of acoustic barriers as deemed necessary in accordance with the PPG.
