At the end of 2008 the Cambridgeshire Local Authorities and Cambridgeshire Horizons commissioned a joint technical study referred to as the "Cambridgeshire Development Study". This study was used to inform the preparation of the strategic policy advice that Cambridgeshire County Council provided to the East of England Regional Assembly (EERA) to assist its review of the Regional Spatial Strategy.
A project team led by WSP and including SQW, Cambridge Econometrics and Pegasus undertook the study which was published in July 2009.
