Welcome to North Mymms District Green Belt Society
Fighting for the Green Belt that shapes our villages.
For over 50 years we’ve stood between North Mymms and inappropriate development — scrutinising planning applications, challenging the Local Plan, and keeping our countryside open for the next generation.

Green Belt under threat, right now
The Local Plan has earmarked land across the parish for housing. Here’s what we’re watching most closely.
Brookmans Park
Three sites around Golf Club Road plus land west of the railway station — 524 new dwellings proposed in total.
Little Heath
Two sites near Hawkshead Road earmarked for 135 dwellings, encroaching on open Green Belt land.
Welham Green
Marshmoor’s employment scheme and 80 homes, plus 12 further pitches proposed at Foxes Lane.

We’ve stopped inappropriate development before.
In 2014 the Secretary of State refused planning permission for a waste incinerator at New Barnfield. When the developer appealed, we stood alongside allied local groups until, in 2015, they dropped it for good. It’s the clearest proof that a strong, well-organised local voice changes outcomes.
Green Belt protection policy has hardened since that original decision — strengthening the case against inappropriate development ever since.

We’re looking for our next Chairman.
The committee is entirely made up of local volunteers — and the Chairman’s role has been vacant since June 2026. If you care about North Mymms’ countryside and can spare some time, we’d love to hear from you before next year’s AGM.
