British Standard 5837:2012 Trees in relation to design, demolition and construction -
Recommendations clearly sets out the requirements for tree retention in proximity to
development and will be used as the benchmark for considering development proposals.
Policy DM01 of the Adopted Barnet Development Management Policies advises that trees should be
safeguarded. When protected trees are to be felled the council will require replanting with suitable
size and species of tree where appropriate. High quality landscape design can help to create spaces
that provide attractive settings for both new and existing buildings, contributing to the integration of a
development into the established character of an area. The council will seek to retain existing wildlife
habitats such as trees, shrubs, ponds and hedges wherever possible. Where trees are located on or
adjacent to a site the council will require the submission of a tree survey with planning applications
indicating the location, species, size and condition of trees. Trees should be retained wherever
possible and any removal will need to be justified in the survey. Where removal of trees and other
habitat can be justified appropriate replacement should consider both habitat creation and amenity
value.
Trees make an important contribution to the character and appearance of the borough. Trees which
are healthy and are of high amenity value can be protected by the making of a Tree Preservation
Order (TPO) under the Town and Country Planning Act 1990. Tree Preservation Orders can help to
protect trees from inappropriate treatment and prevent their removal, as permission must first be
sought from the council to carry out most types of tree surgery.
Appropriate protection of TPO trees and those identified for retention will be expected in line with
good practice during construction of a development.
National Planning Policy Framework section 118: Planning permission should be refused for
development resulting in the loss or deterioration of irreplaceable habitats, including ancient woodland
and the loss of aged or veteran trees found outside ancient woodland, unless the need for, and benefits
of, the development in that location clearly outweigh the loss.

REPORT
2.0 Description of proposal
Erection of a new two storey dwelling. New vehicular access to provide off-street parking.
Associated refuse and recycling and cycle storage.
3.0 Documents reviewed
Proposed site plan and section 4942-19-101
Street view and objectors comments and photographs.
4.0 Discussion
The rear garden of A1 Shelley close is larger than the surrounding properties 16m x 31m
and google street view in 2018 shows that the end part of garden is left to trees and mature
shrubs. Recent photographs show these trees have been removed.
Mature trees and shrubs are retained along the boundary with Glendale Avenue. The
applicant has not provided any information in relation to the impact the development will
have on these trees. Retaining this feature is vital to screen the proposed property from
the gardens of Glendale Avenue.
5.0 Landscape
The proposed building 15m x 10m is large for the plot leaving no meaningful space to
provide replacement trees and screen the property from Glendale Avenue. And the
garden has been divided disproportionally, leaving the 1A with a 6m deep garden. This
should be increased is depth to allow for better amenity space.
The proposed crossover also requires the removal trees and shrubs which will further
reduce the once sylvan character of this part of Shelley Close.
6.0 Ecology
None needed
7.0 Recommendation
Objection
Reason:
Insufficient information and space to provide replacement planting for trees removed prior
determination of the application. Contrary to local planning policy DM01 of the Barnet Local
Plan and policy 7.21 of the London Plan.

9.0 Informative
Tree and shrub species selected for landscaping/replacement planting provide long term
resilience to pest, diseases and climate change. The diverse range of species and variety
will help prevent rapid spread of any disease. In addition to this, all trees, shrubs and
herbaceous plants must adhere to basic bio-security measures to prevent accidental
release of pest and diseases and must follow the guidelines below.
“An overarching recommendation is to follow
BS 8545: Trees: From Nursery to
independence in the Landscape. Recommendations and that in the interest of Bio-security,
trees should not be imported directly from European suppliers and planted straight into the
field, but spend a full growing season in a British nursery to ensure plant health and non-
infection by foreign pests or disease. This is the appropriate measure to address the
introduction of diseases such as Oak Processionary Moth and Chalara of Ash. All trees to
be planted must have been held in quarantine.”
