How
much graffiti is there in the area where you live?
There are 198 National Indicators (NI) that were
identified by the Government in November 2007. One of
them is the NI 195 Cleanliness Performance Indicator,
which has been developed to measure the cleanliness
of the local environment, as a member of the public
would see it.
Each
area surveyed is given one of seven grades
and when all the results are combined they provide an
overall percentage for your
Council. The Council is required to submit the results
of the regular graffiti surveys undertaken within their
borough. Comparisons can then be made with previous
inspections and a more active stance against graffiti
encouraged.

The
grading system at work
|
| Grade
A – The transect is completely free of graffiti. |
Grade
B – Some graffiti is present, but it is minor
in extent, and many people passing through the transect
would not notice it.
|
|
|
|
Grade
C – Graffiti is present to the extent that
it would be clearly visible to people passing through
the transect, and visible at a distance from at least
one end of the survey transect. |
Intermediate
Grades:
Grade
B+ between A & B
Grade B- between B & C
Grade C- between C & D

Thank
you to ENCAMS
for providing these photographs. |

Grade
D – Graffiti is extensive over a large part
of the transect and is likely to be clearly visible and
obtrusive to people passing through the transect, and
visible from any point on the transect. |

What is a transect?
A ‘transect’ is the name given to an area land or highway
that is sampled as part of a Cleanliness survey, and
on which a grade is given. There are broadly two types
of transect: one on highway sites and the other on recreation
and other open areas. A transect on a highway is normally
50 metres long, extending the whole width of the street
A transect in an open recreation area may measure up
to 50 metres by 50 metres but it may be broken down
into several smaller areas.

How is the overall percentage calculated?
Each
transect that is inspected is graded. If that grade
is A, B+ or B it passes, B- is a half fail and C, C-
and D is a fail. The overall percentage is the number
of transects that fail. The lower the percentage the
better.
