of the Lickey Ridge, a formation of hard quartzite. Panoramic views over the city of Birmingham and surrounding countryside can be seen from the top of these hills. The Lickey Hills area is of significant geological interest due to the range and age of the rocks. The stratigraphic sequence, which is the basis for the area's diversity of landscape and habitat, comprises: Barnt Green rocks – Precambrian tuffs and volcanic grits Lickey Quartzite – a Cambrian quartzite Keele Clay – a Carboniferous clay Clent Breccia – a Permian breccia Bunter Pebble Beds – beds of Triassic water-worn pebbles Economy With the demise of the Longbridge Motor Factory there is little in the way of major employment in the immediate area. Rednal barely existed prior to the factory, coming into being in its current form as a result of four events. Firstly the opening of the Austin motor works at Longbridge in 1905, secondly the extension of the area of the City of Birmingham to the northern boundary of Cofton Hackett in 1911. Thirdly the break-up of the Earl of Plymouth's estate by auction in 1919, and lastly the extension of the Birmingham tramlines to the Rednal terminus in 1924. These events had carried Rednal very rapidly from the rural age of the horse and cart to that of the motor car and bus, and from a community depending chiefly on farming to a delightful dormitory for people nearly all of whom now travel into central Birmingham to work. Most of the shops are in an area on the southern edge of the village that was administratively transferred from Kings Norton only in 1911. The previous MG Rover site was purchased by St Modwen and discussions since 2006 have taken place between residents, county, district and parish councils, West Midlands Development Agency and central government officials on suitable development plans for the site. The 2008 downturn in the worldwide economy has slowed the progression of any new development. Situated where the Bristol Road meets Longbridge Lane, the Longbridge Technology Park was completed in late 2007; in 2008 one of the two buildings is occupied but the other is still vacant. A major development aimed to improve the Longbridge ward was the Great Park development in Rubery by Corporate Land Developments Ltd. The site just off junction 4 on the M5 Motorway has been developed into a community with offices, houses, industrial
