Creating the Place; Fix F, Green Edges and Corridors; 5, Employment Site Edge:

The provision of new or enhanced hedgerow planting buffer between the existing employment site and proposed surrounding development is supported.

The edge to the employment site should also ensure that the proposed surrounding development is sufficiently offset from the existing employment uses to avoid any adverse impacts. 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.

It is therefore essential that the employment site edge which comes forward as part of the Bourn Airfield New Village 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 and the provision of acoustic barriers along this edge as deemed necessary (to be provided at the developer's expense) following detailed assessment in accordance with the PPG.
