We are required by Cadent gas to lift the tree line across the rear of the gas compound. The over hanging trees cause a security risk to critical gas infrastructure & a climb risk. We're looking to prune back the over hanging tree line to max 4m avoiding any unnecessary work, this is only to reduce the climb risk on site

What these statistics cover

These figures describe applications collected by PlanningTrack for Welwyn Hatfield Borough Council, across all dates currently available. They are a partial dataset, rather than an authority-wide performance measure. The date range does not establish continuous historical coverage.

The approval percentage is approved records divided by approved plus refused records. Pending, withdrawn and unknown outcomes are excluded. No percentage is shown until there is an approved or refused record.
