This application is with Three Rivers for determination, against a statutory target of eight weeks. Over the last year Three Rivers decided amendment applications in a median of 63 days. More in our guide to how long planning decisions take.

An amendment application makes limited changes to a permission that already exists; anything beyond modest adjustment needs a fresh application. More in our guide to planning application types.

  The work is to pollard the trees, they were last done in 2020 since then part of the site around the trees has been developed and now a significant reduction in the structural frame work of the trees would make them more appropriate to the setting. The trees have no open public view, the trees are significant to the site as a landscape feature of pollards and they will continue to be this, although smaller and more managed. Please see accompanying documentation.
