Councils HS2 Information

The High Speed Two Railway is going to be built after having received Royal Assent in Parliament, and will affect the districts in very significant ways. Chiltern and South Bucks District Councils have decided to introduce a new website to allow residents and interested parties to be kept informed over the next 6 years.

We will provide information and updates on the panels which were formalised through a legal assurance attained through petitioning in the Houses of Parliament, these are the Chilterns AONB Review Group and the Colne Valley Regional Park Panel. We will also provide information on the two types of applications that the Local Planning Authority will be receiving over the next 6 years, these are called Schedule 17 consent approval applications and Section 61 construction applications. Finally we will also provide information and updates on the Community and Business Funds which HS2 are providing to local communities and businesses to apply for the grant which will be available over the next 11 years.

HS2 Reveals Colne Valley Viaduct Specimen Design

The concepts were developed by independent specialist architects Martin Knight Associates in consultation with the Colne Valley Regional Park Panel, and the HS2 Independent Design Panel, consisting of world-leading architects, designers and experts in sustainability. The viaduct concept document explores a range of options and ideas for how it can sensitively and aesthetically sit within the Colne Valley, whilst addressing the technical demands of the project. It will help to inform further design work and technical development by Align, the main civil engineering contractor for HS2 between the Colne Valley Viaduct and the northern portal of the Chilterns Tunnel. Align will engage with the local community on these designs in Spring 2018.
