BS5837 Tree Reports and Tree Surveys in Ashtead
Some enquiries need baseline survey information. Others already have a survey and need an AIA, AMS, Tree Protection Plan or supervision. We review what is already there before recommending more work.
Send the plans plus any Mole Valley wording you already have. If the design is still flexible, we can use the survey/constraints information to help the architect. If permission is already in place, we can concentrate on the condition and site-protection side instead.
For Ashtead applications, send the current drawings and any Mole Valley wording rather than trying to guess which BS5837 document name the council expects. We can identify the stage and quote the proportionate survey/report package from there.
For this sort of job we normally check how close the excavation gets, whether the contractor has enough working room, what happens with drainage/access, and whether the finished extension still makes sense next to the retained crowns.
Architect-led work in Ashtead is much easier when everybody uses the same base information. Tree references, crowns, RPAs and the planning layout should stay coordinated from the first design discussion through to the AIA and any later protection documents.
Use the wording from Mole Valley District Council as the starting brief. If it asks for a Method Statement, an impact report will not answer the condition. If it asks for impact information, a protection drawing on its own is not enough. We match the work to the actual request.
If the architect changes the Ashtead design after the report is drafted, send the new drawing before the application goes in. Updating a live technical package is normal; submitting mismatched information is what causes avoidable questions.
If the council has asked for tree information, send the exact wording.
A request for a “tree report” does not always mean the same document. At the early design stage it may mean a BS5837 Tree Survey and Tree Constraints Plan. Once a planning layout exists, the missing piece may be an Arboricultural Impact Assessment. After permission, the authority may be asking for an Arboricultural Method Statement, Tree Protection Plan or supervision before work starts.
You do not need to make that decision yourself. Forward the email, validation request, tree-officer comment or planning condition and include the current drawings. We will review what is already available and explain the next useful step before you instruct.
