Arboricultural Impact Assessment (AIA)

Our detailed tree impact plan identifies which trees should be retained, removed, or pruned, with clear recommendations for each. We assess the potential impact of any tree loss, propose effective mitigation measures, and ensure all pruning complies with BS3998:2010 standards for safe, precise, and professional work.

We carefully assess the indirect impacts of development on surrounding trees, including site access, working space, and material storage. Our expert approach delivers practical, straightforward solutions to overcome real-world challenges when building close to trees.

Our Arboricultural Impact Assessments ensure that demolition and removal of hard surfaces are carefully planned to avoid harm to retained trees. We assess the proximity of trees to demolition zones, recommend appropriate ground protection, and advise on facilitation pruning where necessary to keep your project compliant and your trees safe.

Where possible, foundations should be positioned outside the Root Protection Areas (RPAs) of trees. If building within RPAs is unavoidable, specialist foundation designs—such as mini-piles or cantilevered systems—can be used to minimize root damage. Our experts provide practical advice on the feasibility of these solutions to keep your project compliant and on track.

Installing hard surfaces within Root Protection Areas (RPAs) can damage tree roots, but these impacts can be minimized. We can recommends the most effective techniques and design adjustments to protect trees while allowing your project to move forward smoothly.

Compacted soil can severely affect tree health, growth, and survival. We design practical solutions and engineering adjustments to maintain adequate uncompacted soil space for trees while ensuring stability for roads and paved surfaces.

New developments must carefully plan the placement of drainage, underground utilities, and above-ground services in relation to retained trees. We recommend keeping all services outside Root Protection Areas (RPAs) and away from tree crowns, and where this isn’t possible, we provide specialist methods to keep your project on track without compromising tree health.

We assess the impact of retained tree crowns on new structures, including potential shading. Our tailored Arboricultural Impact Assessment considers the benefits of dappled shade and the growth characteristics of each species, ensuring your design avoids excessive light obstruction while accommodating future tree development.
