Alcohol-related disorder in and near bars in Derby fell 41% after individual action plans were implemented at 20 venues.
The Bar Futures scheme in central Derby saw officials focus on 20 bars and study problems over a three-week period. This could be used to instigate a voluntary code of practice with the venue to remedy the problems identified. Measures could include employing more doorstaff at certain times and increasing numbers of glass collections.
Free workshops, attended by bar managers and doorstaff as well as councils and police, gave advice on responsible retailing.
The impact of the changes is monitored over a three-week period. Derby Community Safety Partnership, the council and police-backed group behind the scheme, said numbers of incidents fell from 4,222 to 2,491 — or 41% — between the first observation period and the second.
There was a 38% reduction in recorded incidents of violence (2,289 to 1,414) and 38% fall in "triggers of violence", such as drunkenness.
Bar Futures was linked to the 13.1% fall in reported alcohol-related violent crime in the city centre since April 2009. Derby Pubwatch chairman Dave Lalor welcomed the scheme, particularly the workshops: "As a refresher, it was very useful."
