considered to be appropriate for a development of this size. A condition is
recommended requiring further details for the positioning of the ASHPs, PV panels,
solar collectors and natural ventilation stacks to ensure their acceptability (condition 31).
3.51 A commitment has been made for the newly built component of the application to
aim to meet the 'Excellent' level of BREEAM, in compliance with the London Plan's
policies on sustainable design and construction (policy 5.3 and associated).
Flood Risk and Sustainable Urban Drainage Systems (SUDS)
3.52 Policy DM H3 of the Development Management Local Plan seeks to promote
development which incorporates measures to reduce water use and the risk of flooding.
The site is within the Environment Agency's Flood Zone 1 which indicates a low risk of
tidal flooding. A school is defined as a `more vulnerable' category of development, but
this is no different from the existing uses on the site. Given the position of the site and
the existing uses of the buildings, it is considered that the development would not be at
greater risk from tidal flooding.
3.53 The outdoor spaces to the school would be enhanced with improved landscaping.
This is welcomed, as the current site is largely impermeable which directs the majority
of surface water run-off into the public sewer system, with parts of the site potentially
susceptible to surface water flooding during a heavy rainfall event. The proposed
redevelopment provides an ideal opportunity to improve surface water drainage at this
location, including the integration of sustainable drainage systems (SUDS). The area of
permeable surfaces to be included within the site would increase as a result of new
planting and soft landscaped areas, in compliance with London Plan policy 5.13 on
sustainable drainage. Due to the underlying clay soils the site is generally unsuitable for
permeable surfaces, however, and it is therefore proposed to attenuate rainwater by
storing surface run off in tanks for gradual release, which would be adopted for
1,245sq.m of new hard surfacing and roof space and would reduce surface water runoff
in line with the 50% minimum reduction targets set in the GLA SPG on Sustainable
Design and Construction and Core Strategy policy CC2 (condition 13).
Contaminated land
3.54 Potentially contaminative land uses (past or present) are understood to occur at,
or near to, this site. Conditions are recommended to ensure that no unacceptable risks
are caused to humans, controlled waters or the wider environment during and following
the development works, in accordance with Borough Wide Strategic Policy CC4 of the
Core Strategy (2011) and policies DM H7 and DM H11 of the Development
Management Local Plan (2013) (conditions 32-37).
Tree protection
3.55 A condition is recommended requiring the implementation of satisfactory tree
protection measures for all retained trees, to ensure that the development would not
have an adverse impact on any trees on site (condition 11). Subject to this condition it
is considered that the development would be acceptable having regard to its impact on
trees, in accordance with policy DM E4 of the Development Management Local Plan
(2013).
Community Infrastructure Levy (CIL)
3.56 Mayoral CIL came into effect in April 2012 and is a material consideration to which
regard must be had when determining this planning application. In this case, the
application proposes a building and extensions for educational use for which the CIL
