Get a tree-mendous survey

On development sites trees are both important assets, but also potential constraints. Did you know that NWS offers the same development-advice service for trees as it already offers to clients for ecology ?

On the positive side, when managed well trees form key opportunities for wildlife, offer visual amenity to complement the architectural elements and can add a strong sense of place to new developments. They also create micro-climate buffers to sites by contributing screening and shade, reducing wind speed and turbulence, intercepting dust and rainfall, and stabilising temperatures. Mature trees add significant value to properties.

Conversely though, development that doesn’t consider tree roots, hazards, future growth and how the built environment relates to these natural assets will swiftly run into problems. Planning authorities – normally via a BS5837 survey – will carefully check how any new development relates to trees in and around the development site, and how they will be managed in the future.

Tree surveysAs part of the BS5837 survey report, we will assess the value of trees based on their health, remaining lifespan and amenity impact. We provide a Tree Constraints Plan (TCP) showing root protection areas and existing and future crown spreads in a format to suit the client. This is used to initially inform architects when designing site layouts. The TCP helps to inform future tree management and immediately identifies necessary tree works – including hazards.

An Arboricultural Implications Assessment (AIA) follows final design, where the impact of the design proposal on the surrounding trees is assessed as well as the interaction the trees will have on the finished development. This information informs the Tree Protection Plan (TPP) which gives advice on protective measures for the trees on site. The TPP also gives clear indications of potential conflict between trees and the proposed site layout.

Often following planning permission is the Arboricultural Method Statement (AMS), which specifies tree protection measures and any specialised construction techniques. An AMS provides the information package for contractors to fully protect trees during construction and is helpful for tendering works. In our tree surveys and reports, we will also offer guidance on replacements for trees removed and any new planting specifications.
