The growth population of could be housed in a combination of:
Partial Town Growth Zones (TGZ’s) - urbanisation solely in the existing fabric of the towns within the 1km radius pedshed of the rail stations at: - Stevenage
- Hitchin
- Letchworth Garden City
- Baldock
- Knebworth
- Watton at Stone
Full Town Growth Zones (TGZ’s) – as above but including Green Belt land within the pedshed of the rail stations at: - Baldock
- Arlesey
- Knebworth
- Watton at Stone
New Green Quarters - new neighbourhoods around new stations added to existing towns - Possible sites are: - Two in Stevenage;
- one serving Lister Hospital, the other at Bragbury End at the south eastern extremity of the town
New Green Towns - new village clusters located around new railway stations – Possible locations are: - Arlesley Town
- Ickleford
- Woolmer Green
Four possible scenarios have been tested. Each scenario analyses an alternative means of accommodating the increased population:
Scenario 1: No Green Belt Development. Development only in Town Growth Zones around existing rail stations, but not on Green Belt even where it falls inside a TGZ pedshed
Scenario 2: As Scenario 1 but also developing green belt land within the existing station pedsheds
Scenario 3: New Towns. As Scenario 1 plus construction of 2 New Green Towns around new rail stations at Ickleworth and Woolmer Green
Scenario 4: Enlarging Existing Towns. As Scenario 2, plus growth within New Green Quarters around new stations on the edges of Stevenage.
Two housing densities are examined for each scenario: - Average – a mix of densities between 30 and 80 dwellings per hectare
- Medium – a mix of densities between 30 and 120 dwellings per hectare
NOTE: These densities apply to the built areas of pedsheds. As each pedshed has approximately 35% open green areas (parks, etc.) the overall densities are much lower. | The potential to provide for the even growth target population is as follows:
