Type of area: Public Greenspace Area
Last updated: October 2021

A major housing development is proposed at Chapelgarth’s 112-acre site as part of a 20-year regeneration programme in Sunderland. The landscape strategy aims to enhance the natural green space and provide parks and green spaces for current and new residents. There will be a green buffer between Weymouth road and the new development which will include drainage ponds for water management. At the heart will be Central Park, defined by the mature trees and hedge grows, which are already in place. A large "Sustainable Alternative Natural Greenspace" will be created and Sustainable Drainage Systems will be installed throughout the neighbourhood (Ref1).

Creation of new green areas

Project objectives

To develop village-style neighbourhoods in Chapelgarth with accessible open space in a way that protects the woodland areas, naturally manages flood water, enhances natural greenspaces and creates new greenspaces (Ref 1).

Implementation activities

1. Create 150 new and diverse homes (5% to be 2 bedroom houses, 20% to be 5+ bedroom houses and 75% to be 3 or 4 bedroom houses), 2. Install swales (shallow vegetated channels to slow surface water run-off), 3. Install drainage ponds, 4. Plant trees to capture surface water, 5. Provide natural greenspace, 6. Maintain buffer zones around woodland areas and hedgerows, 7. Create a Central Park, 8. Create accessible (at least 2 hectares) woodland within 500 metres from every residential building, 9. All residents will live no more than 300 metres away from at least 2 hectares of accessible green space (ref 1 & 2), 10. Two areas are allocated to become allotments (Ref 2), 11. Create raised earth bund and green barrier to deflect noise from the A19. (Ref 2)
