Streets free of graffiti

Our goal
A representative sample of sites around the borough are inspected and graded according to the amount of graffiti in that area. Each site is given a grading assessment based on the 4-point scale set out in the Code of Practice on Litter and Refuse (COPL&R), ranging from Grade A (clean) to Grade D (heavily affected). This measure is based on the percentage of sites surveyed for graffiti that do not fall below a Grade B.
Bigger values are best
