Planning committee

Decided by Gwynedd Planning Committee on 13 Jul 2026.

Approved

As officers recommended.

Officers advised approval because the temporary, slender mast could operate without unacceptable landscape, ecological or residential impacts, subject to conditions.
A resident objected over landscape harm, lighting, visibility and possible effects on property value; consultees mainly accepted mitigation or raised no objection.
Members noted the conditions and concerns about future wind-farm infrastructure before agreeing to approve by resolution.

Site constraints 3

Nutrient neutrality catchment: River Dee

New homes and overnight accommodation must show nutrient neutrality before approval.

Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.

Agricultural land, grade 4

Poor quality farmland, not best and most versatile. 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.

Also on the record
