1. The green belt surrounding Knebworth makes a significant contribution to protecting the space between the village and the surrounding villages and Stevenage. Removing it will likely mean there is a considerable danger of coalescence, destroying the identity of Knebworth. Developing KB1 will remove the green-belt buffer on the west of the Knebworth.
2. KB1 is next to the A1(M) - not only will people living in houses built here suffer from noise pollution, this section of the A1(M) is the most congested and polluted part of this motorway.
3. Access to KB1 is an issue. Deards End Land is a narrow road with a narrow railway bridge unsuitable for heavy traffic. The plan needs to include new, wider, access routes to KB1.
4. KB1 includes a conservation area. This will be damaged if this area is developed according to the current plan. Furthermore, there will likely be a negative impact on wildlife and Knebworth woods site of special scientific interest. The plan needs to include safeguards to preserve these areas.
