HILLINGDON UNITARY DEVELOPMENT PLAN - London Borough ...

Shopping Hierarchy
The Plan includes a six level hierarchy of shopping areas (as set out in Tables 8.1 and 8.2) in order to provide a
distribution of shops which minimises the need to make long shopping trips and yet provides a range of shops,
allowing customer choice and opportunities for new and existing retailers.
Sites of Borough Importance
Areas identified by the London Ecology Unit as of Borough significance for nature conservation. There are two
types of Borough sites; Grade I, the best; and Grade II, being other sites, which while not being of the same
intrinsic quality as Grade I sites, nevertheless do contain important wildlife habitat.
Sites of Local Importance
Areas aimed chiefly at remedying deficiencies of locally accessible wildlife sites. They do not have the intrinsic
nature conservation interest of Metropolitan or Borough sites, but have at least some wildlife value or potential
for such use.
Sites of Metropolitan Importance for Nature Conservation
Area identified by the London Ecology Unit as of metropolitan significance for nature conservation.
Sites of Special Scientific Interest
Notified by English Nature as an area under the Wildlife and Countryside Act 1981, or special interest by reason
of any of its flora, fauna, geological, or physiographical features.
Social Housing
Social housing is affordable housing that has been publicly subsidised, to ensure that people on low incomes can
afford to rent or buy adequate housing.
Special Needs Housing
This is housing for people who require specially designed dwellings because of physical and/or sensory
impairment and for people who need support to live in the community.
Strategic Advice
Advice submitted by LPAC to the Secretary of State for the Environment as the London Boroughs’ views on
matters to be included in Strategic Planning Guidance.
Strategic Centre
A shopping and commercial centre with a catchment area which extends outside the Borough, with good public
transport links to a wide variety of destinations.
Supplementary Planning Guidance
Additional information and advice forming detailed guidance on how particular policies in the UDP should be
implemented.
Sustainable Development
Development that meets the needs of the present without compromising the ability of future generations to meet
their own needs.
Tandem Development
Tandem development consists of one house immediately behind another and sharing the access. This is
generally unsatisfactory because of the difficulties of access to the house at the back, and the disturbance and
lack of privacy suffered by the house in front.
Traffic Management
Measures undertaken to improve the environment, traffic flow or highway safety by controlling the movement
of different types of vehicles, and regulating places for parking.
Tree Preservation Order
An order made by the Local Planning Authority under Section 198 of the Town and Country Planning Act 1990
to protect selected trees or woodland if their removal would have a significant impact on the environment and its
