Planning application

12 Mardley Hill Welwyn AL6 0TN
Proposal
TPO 24 T2 - 1 x Oak to remove in sections to ground level. Tree is suppressed by neighbouring tree leaving a high canopy, blocking lights to neighbouring gardens as part of a larger group **a reduction doesnt seem suitable due to the existing canopy shape. Reducing the tree significantly will create a denser thicker poorly attached growth. Client happy to replant T3 - 1 x Beech tree to reduce overhanging lateral branches by approximately 2m. Reduce lateral overhang to no 16 as tree is too close to boundary and excessive overhang is leaving bird poo on kids play equipment

What happens while it is decided
The process from here
This application is with Welwyn Hatfield for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
About trees applications
How this application type works
Tree applications cover work to protected trees: those under a tree preservation order need consent for pruning or felling, and trees in a conservation area need six weeks written notice before work starts. The council assesses the amenity value of the tree and can refuse consent, approve it with conditions, or in conservation areas make a preservation order in response.
