Excavation in Root Protection Areas (RPAs) (SGN 7)
Establishes:
- Guidelines for conducting excavation within RPAs to minimize damage to tree roots.
- Recommends the use of hand tools or compressed air soil displacement to avoid mechanical excavation.
- Specifies that roots over 2.5 cm in diameter should only be cut with the approval of the supervising arboriculturist.
- Protects exposed roots from drying out and temperature extremes using dampened hessian or similar coverings.
Weak Points:
- The success of these measures heavily relies on strict adherence to guidelines and supervision.
- Unauthorised or improper excavation practices could lead to significant damage to tree roots and compromise tree health.
What aspects should be evaluated in relation to this document?
ENVIRONMENTAL IMPACT
Review Excavation Practices:
Ensure the document outlines safe excavation practices within RPAs to minimize root damage and soil disruption.
DESIGN AND APPEARANCE
Assess Excavation Impact on Design:
Evaluate how the proposed excavation methods will integrate with the overall design, ensuring minimal visual and structural impact.
RESIDENTIAL AMENITY
Consider Construction Impact:
Review how excavation activities will affect residents, focusing on noise, dust, and accessibility. Measures should be taken to minimize disruption.
