What is Proposed?
The current Harlow North proposals seek planning permission for a major urban extension to the north of Harlow, Essex. The application site covers approximately 850 hectares of predominantly green belt land, stretching from the town's existing northern boundary toward the villages of High Wych, Sawbridgeworth, and Hatfield Heath.
The scheme includes a mix of residential, commercial, and infrastructure development. The residential component alone envisages between 8,500 and 10,000 new homes, which would effectively double the population of the current built-up area of Harlow within a single development phase. This scale is unprecedented in the district's modern planning history.
Beyond housing, the proposals include two new primary schools, a secondary school, a local centre with retail and healthcare facilities, employment land, and extensive road infrastructure including a new northern bypass and multiple junction upgrades on the A414 and M11.
Independent Technical Concerns
STOP Harlow North has commissioned independent technical assessments across multiple disciplines. The findings consistently identify significant flaws in the developer's evidence base:
- Transport: Our consultants found that the traffic model uses outdated trip generation rates and underestduces HGV movements during construction by approximately 40%.
- Ecology: Phase 1 habitat surveys identified ancient woodland, veteran trees, and breeding bird populations not adequately addressed in the Environmental Statement.
- Hydrology: Surface water runoff modelling does not account for climate change rainfall projections (UKCP18), risking increased downstream flooding.
- Air Quality: The AQMA boundary would expand significantly, bringing additional properties into the legally designated zone.
- Noise: The M11 corridor noise contours suggest hundreds of dwellings would be built in excess of WHO nighttime noise guidelines.
Policy Context
The site is designated green belt in the adopted Local Plan. National planning policy permits green belt release only in "exceptional circumstances" after all other options have been exhausted. Our analysis, supported by planning law experts, argues that the council has not demonstrated the required sequential test or evidenced the alleged strategic need at this scale.
The government's Levelling Up and Regeneration Act 2023 introduces new requirements for nutrient neutrality and biodiversity net gain. Preliminary assessments suggest the Harlow North site would struggle to meet these statutory tests without off-site mitigation at considerable public expense.
