Proposal

The 180 acre landholding at Ty Mawr lies on the watershed between the Rivers Usk and Wye. We hope to add ponds and leaky dams to the land we manage, both to benefit biodiversity and to slow down flows into tributaries of those rivers: the Trothy and the Pontyrhydan Brook. The Ty Mawr fields are a mix of pasture and arable with very little ecological value. The pond proposals at Ty Mawr are designed to compliment those recently constructed on the adjacent Old Lands holding, which flow entirely into the Trothy, as well as establishing initial headwater hydrological control on part of the Pontyrhydan Brook. Ty Mawr is a Demonstration Farm for best practice regenerative farming, including Wildfarmed cereals and nutrient and livestock management with a strong focus on soil health. Ty Mawr holds knowledge exchange workshops for farmers, agronomists and other stakeholders and is therefore an excellent choice for demonstrating how Natural Flood Management can sit alongside arable management. There 7 small ponds, scrapes and leaky dams designed in conjunction with MCC. Data via plota.co.uk

Site constraints 3

Grade II* listed: Gatehouse to Ty Mawr
List entry 2093 · 20 m away · 3 more listed buildings within 150 m (1 Grade II*, 2 Grade II)
Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.

Nutrient neutrality catchment: River Usk
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 2
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 11 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.
