Trees 1, 2, and 3 are deemed to be most likely impacted the most by the proposals due to the works
proposed. However given the topography of the site and the existing hard standing, the expected
root development is highly unlikely to reflect the calculated NRZ prediction and root proliferation
towards the existing hard standing surface such as the driveway and the road is expected to be
minimal. Impacts towards the retained trees are therefore expected to be minor and given the correct
protection measures the trees are assumed to remain viable.
