Bourn Parish Council express concerns over Countryside's traffic mitigation measures

Bourn Parish Council recently published their April newsletter which led with the following article:

"Bourn Airfield – Countryside Properties Consultation 
 
Bourn Airfield developers, Countryside Properties, attended a consultation meeting with the Parish Council on 5th March. This was to discuss concerns regarding the impact to local roads and traffic presented by the new development.
 
The Parish Council is extremely concerned about the mitigation measures Countryside are proposing (which just include monitoring traffic through the village) and unconvinced of the accuracy of the traffic metrics upon which they are basing their mitigation proposals. Their proposal includes an intention to create a modal shift of commuting from cars to buses from 4% to 30% to ease congestion. To date this has not been achieved in comparable developments and seems highly ambitious.
 
 
Whilst seeking to assure the Parish Council on the one hand that there would be no adverse impact through the village and on local roads in rush hour, on the other they confirmed that the tolerance /capacity levels on the Cambourne and Hardwick-Dry Drayton roundabouts and routes into Cambridge will be much higher than they are now.
 
It is inevitable that these routes will become seriously congested when both West Cambourne and Bourn Airfield are built out. When challenged on this, their Transport Consultant confirmed that traffic would be adversely affected but said this would not be considered a problem unless the government’s definition of “severe harm” was reached. This is a very low bar and is ill-defined. Essentially, we were told this is happening, traffic through the village and on access roads to employment centres will be significantly affected, and that we need to “live with it”. 
 
The Parish Council is continuing with steps to challenge the adverse impact on our village. "

Clearly there is still much to do to ensure that this development does not begin until a sustainable level of impact on local people and environments is assured.
