If trees sit on or near your site in Lancashire, your planning application is highly likely to require a BS 5837 Tree Survey. Root protection areas, crown spread, access positioning and tree quality all influence whether a layout is acceptable. Without early arboricultural evidence, even small schemes can trigger validation delays, redesign requests or restrictive conditions.
We confirm what’s required quickly and proportionately so your application stays on track.
Across Lancashire, tree constraints most often influence planning where development intersects with established residential areas and regeneration land.
This commonly includes:
Suburban neighbourhoods, where mature boundary trees constrain extensions
Brownfield and regeneration sites, where retained planting influences layout and access
Edge-of-settlement growth, where tree belts shape site capacity
Semi-rural plots, where tree groups fall within foundation influence zones
Lancashire planning authorities expect early and realistic integration of retained trees into site design.
We deliver Tree Surveys for Planning across Preston, Lancaster, Blackburn and neighbouring settlements, supporting residential and commercial development throughout Lancashire.
Lancashire planning authorities rely on clear arboricultural evidence to assess whether development layouts properly respond to existing trees. Trees are a material planning consideration under the Town and Country Planning Act 1990, with national policy reinforced through the NPPF and technical requirements set out in BS 5837 (Trees in relation to design, demolition and construction). Where proposals affect root protection areas, canopy spread or retained tree quality, planners must be satisfied that designs are feasible, proportionate and deliverable.
When arboricultural evidence is unclear or incomplete, applications are commonly delayed, conditioned or returned for revision.
Our Tree Surveys for Planning are commercially aware, proportionate and planning-led, designed to support real-world construction sequencing, access logistics and foundation strategy without unnecessary escalation.
A planning-focused output that Lancashire planners can rely on:
BS 5837 tree survey and constraint data
Root protection area calculations and crown spread mapping
Retention categorisation with management commentary
Clear, decision-ready planning summary
This evidence supports confident layout design and predictable validation outcomes.
Scope and LPA requirements confirmed from site boundary and draft layout. Â
All relevant trees measured and assessed to BS 5837 standards.
Constraints, RPAs and canopy spread mapped for direct design use.
Any integration with AIAs, Tree Protection Plans, drainage layouts or foundation strategies

A BS 5837 tree survey may be needed where trees are present on or close to a proposed development site in Lancashire. This can include residential extensions, new dwellings, rural conversions, access alterations, commercial schemes, and redevelopment projects. The survey identifies tree constraints early so they can be considered before plans are submitted.
A tree survey for planning assesses the species, height, stem diameter, canopy spread, age class, condition, and retention category of relevant trees. It also calculates Root Protection Areas and identifies constraints that may influence building positions, access, drainage, service routes, foundations, and construction methods.
Yes. Trees outside the site boundary can still affect a planning application if their canopies or Root Protection Areas extend into the proposed works area. Neighbouring trees, boundary trees, and woodland edge trees may all need to be considered where development activity could affect their roots or long term condition.
Completing a BS 5837 survey before finalising the layout helps the design team understand tree constraints from the start. This can reduce the risk of avoidable redesign, objections from tree officers, validation delays, or construction issues where Root Protection Areas have not been properly considered.
A Tree Constraints Plan shows the surveyed trees, canopy spreads, retention categories, and Root Protection Areas. It helps architects, developers, and planning consultants understand where trees may restrict development and where layouts, access, or services may need to be adjusted.
Yes. Trees protected by a Tree Preservation Order or located within a Conservation Area may affect what works are allowed and what supporting information is needed. A BS 5837 tree survey helps identify protected or important trees and supports a planning submission that properly considers tree retention and protection.
Yes. Where trees are relevant to the proposal, a BS 5837 tree survey can provide the arboricultural information needed for validation and assessment. Submitting the right information early can reduce further information requests and help the planning authority assess the proposal more efficiently.
Requirements vary depending on whether the site falls within Lancashire County Council, Blackburn with Darwen, Blackpool, or a district authority such as Preston, Lancaster, Chorley, Ribble Valley, or South Ribble. Lancashire County Council provides planning guidance here: https://www.lancashire.gov.uk/council/planning/. Applicants should always check the relevant local authority requirements before submitting.
If tree constraints are not addressed where trees could be affected, the local planning authority may request further arboricultural information before determining the application. This can delay validation, extend assessment timescales, or require changes to the proposed layout, access, or construction methodology.
Depending on the site and proposal, further documents may include a Tree Constraints Plan, Arboricultural Impact Assessment, Tree Protection Plan, and Arboricultural Method Statement. These documents explain how trees influence the development and how retained trees will be protected before and during construction.
