Environmental Appraisal for Transport for London

In December 2007, Colin Buchanan was commissioned by Transport for London (TfL) to undertake a Scheme Identification Study for Henly’s Corner, the signal-controlled junction of the A406 North Circular and the A598 (Regents Park and Finchley roads) in the London borough of Barnet. 

This signalised junction is usually heavily congested during peak hours and has a history of serious and fatal accidents.

Colin Buchanan commissioned GHD to undertake a high level non-statutory Environmental Appraisal (EA) of the eight scheme options being developed for Henly’s Corner.  The primary purpose of the EA was to evaluate the likely environmental performance of the eight junction improvement options, both in order to inform the selection process and to facilitate a TfL determination as to whether a formal Environmental Impact Assessment (EIA) was required for the preferred scheme.

Following successful completion of the EA and the selection of the preferred junction improvement scheme by TfL, GHD was commissioned to undertake supplementary environmental studies to provide more detailed information on key areas identified in the first phase of the appraisal. These specialist studies incorporated a suite of ecological survey work, including a phase one habitat survey, protected species walkover, river corridor survey, and bat activity and emergence surveys, as well as noise and air quality assessments, and an investigation of road drainage and the water environment.

GHD has successfully completed the commission with the EA findings assisting TfL progress the Henly’s Corner junction improvement scheme through the planning process.

GHD is recognised for providing holistic and integrated solutions in managing and preparing project impact assessment and approvals. Our environmental and community planning specialists, engineers and scientists work to better understand complex issues associated with our clients new developments – from concept phase through to decommissioning. This approach delivers better environmental and social outcomes, and reduced approvals timeframes and compliance costs.

GHD focuses on the identification of potential environmental constraints and opportunities in the early stages of a project. This allows environmental and social factors to be reflected in the development of the project and mitigation measures to be devised to minimise potential impacts. In doing so, community acceptance is maximised and delays in implementation are significantly reduced.
