Appointed in August 2025, LUC refreshed and expanded the Green Corridor Study, drawing on current GI best practice and expertise in the Hertfordshire context. The study area covers approximately 16 km², connecting key ecological assets, destination sites, footpaths, cycleways, and bridleways, while maintaining the Green Belt function and providing a vital community resource. The work included updating the evidence base, reviewing policy changes, site walkovers, and developing a landscape-led masterplan with detailed guidance for future GI delivery.

The updated study highlights significant changes in national, regional, and local policy since 2019, including the introduction of the Natural England GI Framework, the Environment Act, Hertfordshire’s Local Nature Recovery Strategy, and the borough’s Transition to Net Zero Strategy. The study identifies five core themes for GI delivery: nature-rich and beautiful places, active and healthy places, thriving and prosperous communities, improved water management, and resilient, climate-positive landscapes.

Analysis revealed the need to restore, expand and connect habitats, provide opportunities for river restoration and naturalisation, improve access to green spaces, and address barriers to active travel. The study also emphasises the importance of promoting sustainable travel options, connecting heritage assets, regenerative farming practices and regeneration of historic mineral workings to support local character and economic vitality.

The Green Corridor Study sets out a comprehensive masterplan and delivery framework, outlining mechanisms for strategic GI delivery through developer contributions, biodiversity net gain, and the Community Infrastructure Levy. Recommendations include adopting robust GI standards, increasing urban tree canopy cover, and promoting nature-based solutions for flood management and climate resilience.

The study’s multi-functional approach will help Welwyn Hatfield Borough Council deliver healthier, more sustainable communities, enhance biodiversity, and support climate adaptation. The evidence and guidance provided will underpin future planning decisions, ensuring that green infrastructure remains central to the borough’s growth and development.

With the completion of the Green Corridor Study evidence base, Welwyn Hatfield Borough Council is well-placed to achieve its vision for a connected, resilient, and vibrant landscape. The recommendations and masterplan will guide the integration of GI into new developments, helping to secure long-term benefits for people, nature, and the local economy. LUC’s next planned phase of work will focus on how the range of GI opportunities can be successfully delivered on the ground, including the provision of a more detailed delivery plan, GI toolkit, and checklist for new development.
