Whether you are a developer, architect or planning consultant with multiple large sites, a builder with small to large sites on the go or an individual householder organising and project managing your own extension works. We are able to assist you in all of these situations for you to achieve your goal.
Additionally, there is a substantial body of research that supports the economic, environmental and social benefits that trees bring to urban areas and the contributions that they make to people’s quality of life and sense of wellbeing.
The Tree Protection Plan (TPP) develops from the BS 5837 tree report, BS 5837 Tree Constraints Plan (TCP), BS 5837 Arboricultural Impact Assessment and BS 5837 Tree Protection Plan (TPP).
This will then identify the issues to be addressed on the BS 5837 Tree Protection Plan (TPP), and measures to be addressed with the BS 5837 Arboricultural Supervision and any necessary Tree Replacement Planting.
The main constraints will be the stem diameter crown spread crown height and the root protection area calculated from the stem diameter, but is also important to record the condition, category, and hazards and work recommendations, their life expectancy, crown spread to the four cardinal points, crown, lowest significant branch height and direction, current and expected maximum height, life stage, physical and structural condition and the theoretical RPA.
All tree work recommendations will comply with the relevant British Standard BS3998 Tree Work – Recommendations (2010), unless otherwise specified in a report, with a clear justification for any deviation from the standard.
Trees also have significant heritage value. This is being increasingly eroded as many large and medium sized trees are being removed as they become unsafe or are simply in the way of proposed development or infrastructure.
Where trees are planted to replace those removed, often they are not given the correct conditions or management they require to enable them to reach maturity. Tree planting should be undertaken in accordance with the new British Standard, BS8545 Young Trees: From Nursery to Independence in the Landscape (2014). Frequently trees of a smaller final size are selected, which will not provide anything like the same amount of benefits.
These can then be transferred from the TCP to the TPP, to show these visually, in 2D, on a Computer Aided Design (CAD) system. We use KeyTree and AutoCAD. In the future with Digital Arboriculture and Building Information Technology (BIM) this will be possible in 3D and 4D (representing changes over time).
Also, site features and layout that will have restricted or impacted on the RPA of the trees shall be recorded on the TPP.
It is not only important to show the tree constraints for all the trees on or adjacent to the site, and the tree protection measures to protect them. These include tree protection fencing (Herras or alternatives) as well as ground protection measures. It is also important to show the areas where site access, and vehicle access will be directed, and where the site offices and facilities, storage of equipment and materials and vehicles will be located.
It will also be required to show any “no-dig areas and “hand-dig” area on these plans.
These plans will need to be to scale, with the scale and paper size record on all versions along with the north arrow and a suitable key.
