Accessibility bands around Watford Junction
Distances are straight-line screening bands. Routed pedestrian access, severance by roads or the railway itself, and gradient will usually reduce the practical catchment, and must be verified on site.
| Band | Indicative walk | Indicative density (dph) | Policy relevance |
|---|---|---|---|
| 0–400m | up to 5 minutes | 55 | Core station area. Highest justification for optimised density under policy L3 and the strongest sustainable transport case under policy TR. |
| 400–800m | 5–10 minutes | 35 | Within the 800m walking catchment used by the NPPF (August 2026) well-connected station tests, including the Green Belt release route under policy GB7. |
| 800–1,600m | 10–20 minutes | Site specific | Beyond the headline walking catchment. Accessibility must be evidenced through routed walking, cycling or bus interchange rather than assumed. |
| 1,600–3,200m | 20–40 minutes | Site specific | Wider travel-to-station area. Relevant to plan-making and cycle/park-and-ride strategies, not to the station-proximity density case. |
Screened land in each walking ring
Live screening of the brownfield land register and constraint layers on planning.data.gov.uk, run for this station on 19 August 2026. Distances are straight-line screening, not routed pedestrian access.
| Ring | Parcels screened | Land area | Brownfield parcels | Within Green Belt | Indicative capacity |
|---|---|---|---|---|---|
| 400m | 13 | 28.17 ha | 13 | 13 | 1,155 homes |
| 800m | 19 | 30.27 ha | 19 | 19 | 1,240 homes |
| 1,200m | 28 | 31.83 ha | 28 | 28 | 1,240 homes |
| 1,600m | 43 | 43.03 ha | 43 | 43 | 1,240 homes |
How the opportunity score is built
The Logical Planning station opportunity score weights accessibility, housing need, Local Plan opportunity, brownfield potential, policy support and development pressure, then deducts penalties for severe flood risk and for heritage, ecological and infrastructure constraints. Where a component has no published evidence it is omitted from the calculation and reduces the data confidence figure rather than being assumed.
Current indicative score: 35.0/100 (Moderate) with 66% data confidence, based on 5 verified data points held for this station. Watford Junction scores 35.0 mainly on developable land, with 19 brownfield parcels screened inside 800m, reduced by 10.0 points for screened Green Belt coverage.
Components with no published evidence at present, excluded from the calculation: transport accessibility, housing pressure, planning evidence, market and economic pressure.
Logical Planning provides planning intelligence and opportunity assessment. Scores are indicative and are not planning advice or confirmation that planning permission will be granted.
