  1. The Issues of Greenfield v. Brownfield Sites for Housing Developments Where would be the best site for housing in our local area Would it be on a Greenfield site or a Brownfield site?

  2. What is Meant by the Terms Brownfield and Greenfield Sites? Very simple this: • Brownfield- A site that has been built on before. Normally associated with urban areas • Greenfield- Sites that have not been built on before. Often rural/ countryside areas. The government tends to favour Brownfield sites. The reason for this is that they improve run-down areas, but also due to the fact that people really dislike seeing new land being used for development.

  3. Greenfield and Brownfield Issues • You have been given a sheet with a list of issues relating to Greenfield and Brownfield sites • However, they are all mixed up. You need to separate the statements into the following categories • Brownfield Positive • Brownfield Negative • Greenfield Positive • Greenfield Negative • You need to decide on a way to categorise and display the information when you write the statements out. Are you going to write them in columns? Spider diagrams with some sort of colour coding? It is up to you. • The statements are provided on the following slide for discussion Photo used with permission of Jacky Wilson, Winchester City Council Photo used with permission of Flickr user Denis Defreyne under a under a Creative Commons attribution license.

  4. Greenfield v. Brownfield Issues • Brownfield redevelopment eases pressure on Greenfield sites and is more sustainable • Greenfield sites are often on the edge of towns and cities and may have better access, have less congestion, be in a more pleasant environment and have more space and room to expand • House prices would increase in inner city areas as people are encouraged back to the area. This might mean that local people can not afford the houses, and the council will have the problem of providing for them • Infrastructure already exists in urban areas- in Greenfield sites new drainage, electricity, roads etc. would all have to be produced • Light industry and things like Science Parks favour out of town locations on Greenfield sites-they prefer them to Brownfield sites, and crucially so do their workers who are happier to live away from urban areas • New employment opportunities if Brownfield sites are developed • New housing can lead to gentrification (old housing done up- area becomes more trendy and affluent) so the area will improve and things like crime rates will improve • New sites are easier to build on as there is a fresh start, where remains of previous land use do not need to be cleared and is more attractive to retail parks, housing developers etc. • Providing public transport networks is easier in central areas where the population densities are high- investment is focussed in central areas • There is an issue of contamination and making sites safe for development, given what the land may have been used for before • Towns and cities do not want their areas to decay- redevelopment results in more people coming to the area, which helps local businesses. Building on Greenfield sites ‘sucks’ out the core from towns as shop etc. locate on the edge of tons/cities • Using Greenfield sites is not sustainable- there is too much pressure on the rural-urban fringe and the use of Brownfield sites has to be a better option

  5. Groups 1 & 2: You have got to argue the case for putting houses on a site recently made available on the landfill site at Horsea Island in grid square 6304 Groups 3 & 4: You have got to argue the case for putting houses west of Waterlooville in grid square 6709 Having understood the Greenfield and Brownfield issues you have been given the task to find a suitable place for building new houses in the Portsmouth area The Task Complete the first task on the sheet, and then your group needs to prepare the proposal and consider the following things: • What are the advantages of your site? • What are the potential disadvantages of your site? • What issues are likely to arise? • Is it a Brownfield or Greenfield site? Group 5 & 6: You have a free choice! Explain you decisions fully

  6. Watch/Listen to the Presentations/Videos and follow-up tasks • Listen to the presentations and be prepared to question the other groups’ proposals • Which group had the best presentation and why? • Which site was the best and why? • Which site was the worst and why? • What are your general views on the Greenfield v. Brownfield debate? • I deliberately chose the site to the west of Waterlooville as a possible site for development as this is exactly what is going to happen over the coming years. We will examine this in more detail next lesson. Illustrative Masterplan of the new West of Waterlooville development, used with permission of Winchester City Council.
