Decided by Gwynedd Planning Committee on 17 Nov 2025.

Approved

Officers advised approval because the extension would maintain mineral supplies, complete restoration and avoid unacceptable environmental or amenity effects.
Consultees raised no objections overall, while biodiversity advice sought habitat management and protection for nesting birds.
The committee resolved to delegate approval to the Head of Environment Department, subject to conditions.

Site constraints 2

Llyn National Landscape

Great weight to conserving the landscape; major development restricted.

Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.

Agricultural land, grade 3b

Not best and most versatile land (grades 1, 2 and 3a). Source: the Predictive Agricultural Land Classification Map (Defra and Natural England, 2025; the Welsh Government's Predictive ALC Map 2 in Wales), a model rather than a site survey. A site survey can differ.

Where development of farmland is needed, policy prefers poorer land over the best and most versatile (grades 1, 2 and 3a). Three sources: Natural England's post-1988 field surveys, which are definitive where they exist; the Defra predictive map for England (2025) and the Welsh Government predictive map, modelled from the soil map with 3a and 3b split; and the 1970s provisional map, which planners and other services still show, coarser and with grade 3 undivided. Where the provisional and predicted grades disagree, treat the predicted grade as the current estimate and expect an application to carry its own survey.

Not affected

Outside flood zones 2 and 3 · No scheduled monument at the site

Checked on 26 September 2026. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
