Introduction |
| 2.1.1 |
The NI 195 survey is designed to provide a ‘representative’ picture of cleanliness within an authority. More importantly, the survey enables local authorities to compare their performance with national benchmarks (produced annually by Defra’s Local Environmental Quality Survey of England - LEQSE), on a ‘like-for-like’ basis using ten standard Land-use Classes. |
| 2.1.2 |
For this reason, the survey is carried out in a way that is comparable with the LEQSE, including dividing a year’s sample equally over three, four-monthly periods. |
| 2.1.3 |
The survey is designed to be economical to undertake in relation to staff time and material resources. However, maximum economy can only be achieved if sufficient time and care is put into survey planning. |
| 2.1.4 |
The survey planning method described below - based closely on that used for the LEQSE - is designed to be used by people with little or no advance knowledge of the authority. |
