Masterplans
We are committed to the key sites in the Borough identified in the draft Local Plan undergoing a Masterplanning process.
This will ensure that the development meets the needs of the Borough and results in well designed, high quality, sustainable and well-connected environments
A masterplan document:
- outlines principles and requirements for development
- sets a template for guiding development
- helps ensure sites are delivered in a comprehensive and well-planned manner
The masterplanning process involves working collaboratively with:
- other statutory authorities
- community representatives
- local interest groups
- and the landowner and/or site promoter
to develop a vision and strategy for or the development of the site.
Masterplans will be produced in accordance with the site specific requirements set out in the draft Local Plan and all other relevant Local Plan policies.
On 5 March 2024, Cabinet endorsed a supplementary planning guidance document, Approach to Masterplanning.
This provides further information on what is expected of masterplan documents.
Marshmoor Policy Area SPD
Marshmoor (also called Hatfield Innovation Campus by the landowner) is a large strategic site in Welham Green, east of the village and railway line and west of the A1000. It was allocated for employment-led development, including up to 40,500 square meters of employment space and 100 residential units for skilled workers, under Policy SP23 and SADM30 of the Welwyn Hatfield Borough Council Local Plan 2016 - 2036.
The Draft Supplementary Planning Document (SPD) has been prepared by the landowner, in collaboration with officers from Welwyn Hatfield Borough Council and Hertfordshire County Council, to ensure the site is planned comprehensively to maximise benefit to the area. The SPD was consulted on with the local community and others from Monday 10 February to Friday 21 March 2025.
The SPD is due to be considered for adoption by members at Cabinet on 9 July 2025.
Marshmoor SPD SEA and HRA Screening
A Strategic Environmental Assessment (SEA) is required under European legislation for all plans and programmes which may have a significant effect on the environment.
A SEA aims to protect and ensure the environment is considered during the preparation and adoption of plans and programmes, promoting sustainable development.
Not all plans and programmes will require a SEA to be carried out. To decide if a SEA is required, a screening exercise is used to look at the proposals see if a significant environmental effect is likely. We consult three key statutory bodies Historic England, Natural England and the Environment Agency and ask for their views. We have carried out screening of the Marshmoor Policy Area SPD and have determined that it would not require SEA or a Habitats Regulation Assessment (HRA).
A copy of the determination and the statement of reasons may be viewed and downloaded. They are also available to view in reception at the council offices, Welwyn Hatfield Borough Council, The Campus, Welwyn Garden City, Herts AL2 2AE. You may request a copy by emailing planningpolicy@welhat.gov.uk, or telephoning 01707 357000. A charge will be made for hard copies.
