Development Tree Surveys
BS 5837 Surveys for Planning Applications
What is a Development Tree Survey?
A development tree survey is a crucial first step for any construction or extension project where trees are present on or near the site. Conducted strictly in accordance with British Standard 5837:2012, this specialist survey maps the exact location, size, and condition of relevant trees.
The core objective is to provide architects, developers, and planning consultants with the essential arboricultural data they need. This allows your team to design viable, compliant layouts and secure planning permission without facing unnecessary delays or objections from the local council.
Why Commission a Survey Early?
Identifying tree constraints early in the design process is vital. Local Planning Authorities require comprehensive tree data to validate and assess development applications effectively.
Failing to account for Root Protection Areas (RPAs) or tree canopies during the initial design phase frequently leads to costly redesigns, requests for further information, or outright planning refusals. A professional development survey clears the path for a smooth, compliant planning process from day one.
What is Included in the Survey?
We supply the foundational data and reporting required to navigate the planning system successfully. A standard development tree survey includes:
- Topographical Overlay Accurate plotting of all significant trees onto your existing site plans and topographical surveys.
- Tree Categorisation Professional grading of tree quality and retention value (A, B, C, U) to inform your architectural design decisions.
- Constraint Mapping Clear identification of Root Protection Areas (RPAs) and above-ground canopy constraints to define the developable space.
- Foundational Reporting The raw arboricultural data required to produce subsequent documents such as Impact Assessments and Tree Protection Plans.
Frequently Asked Questions
Here are answers to some common questions we receive regarding Development Tree Surveys.
When should I book a development tree survey?
Ideally, you should commission a survey as soon as you have a topographical map of the site and before any architectural layouts are drawn. This ensures you design around the constraints rather than having to alter expensive plans later.
Will the survey tell me which trees I can cut down?
Yes. The survey categorises trees based on their quality and life expectancy. Trees graded 'U' are generally unsuitable for retention, while 'C' grade trees may often be removed if it facilitates significant development benefits, subject to council approval.
Is a development tree survey the same as a BS 5837 survey?
Yes. In the UK, any tree survey conducted to support a planning application must be carried out in accordance with BS 5837:2012. "Development tree survey" is simply the common, descriptive term used within the industry.
Do I need a survey if the trees are not on my property?
Yes. If trees on neighbouring land have Root Protection Areas or canopies that extend into your development site, they must be surveyed and factored into your planning application to ensure they are not damaged during construction.
