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 KB2 will remove the green-belt buffer between Gypsy Lane and the A1(M).
2. KB2 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. This is also the site for the proposed primary school, given the level of pollution here a different site may have to be considered.
3. Access to KB2 is an issue. Gun Lane railway bridge is a narrow bridge unsuitable for additional traffic. The plan needs to include new, wider, access routes to KB1.
4. KB2 includes a conservation area. This will be damaged if this area is developed according to the current plan. The plan needs to include safeguards to preserve this area.
5. KB2 has long-standing drainage issues, resulting in surface water flooding from the A1(M), which the current plan does not address in detail.
