BS5837 Survey: Heritage Estate Development

Tree impact assessment for a 40 acre heritage site. The work balanced tree retention with infrastructure upgrades.

BS5837 Survey: Heritage Estate Development

Balancing the preservation of veteran trees with necessary infrastructure upgrades requires a meticulous approach. This heritage estate required a detailed BS5837 tree survey to inform the development of visitor facilities without compromising the landscape.

A Clear Baseline

The project began with a shared evidence base for the estate team, planners and design consultants. Survey information was structured so every tree constraint could be understood before routes, services and visitor facilities were developed further.

Site Mapping and Categorisation

The initial phase involved mapping and categorising over 300 individual trees across the 40-acre estate. Each tree was assessed for physiological and structural condition, allowing the design team to position new access routes outside critical root protection areas.

The survey provided the exact constraints we needed to respect the landscape while delivering modern visitor facilities.

Working With The Design Team

Regular reviews helped the design team respond to arboricultural constraints as the scheme evolved. This reduced late-stage revisions and kept practical protection measures connected to the wider construction programme.

Arboricultural Impact Assessment

Following the survey, an Arboricultural Impact Assessment (AIA) was detailed to show exactly how the proposed works would interact with the retained trees, specifying the use of cellular confinement systems for paths to prevent root compaction.

The final information was written for practical use on site, giving contractors clear protection areas, working methods and points that required arboricultural supervision.

Protection During Construction

Tree protection measures were sequenced with the works programme so fencing, supervised excavation and no-dig surfaces could be installed at the right stage rather than treated as an afterthought.

Negative Recording

A ‘Walk-over’ or ‘negative recording survey’ can be used on suitable sites. This type of survey involves a non-invasive visual inspection of all the trees within the site, including any potential overhanging third-party trees. However, rather than a full tree stock inventory being produced, only those which pose a risk or requiring management are formally recorded and reported. This approach can be suitable as it is cost-effective for sites with a lower budget however still ensures that risks within the tree stock are identified. It is also suitable to sites with limited or no public access or those with fewer assets to manage.
