What is the maximum permitted height for the slope of a bank in relation to the green?

The maximum permitted height for the slope of a bank in relation to the green is regulated to ensure safety and the integrity of the playing surface in bowls. A slope of 35 degrees is the standard established to provide a balance between maintaining a manageable bank incline for players and ensuring that the bank supports the green effectively without causing disruptions or hazards.

Slopes that exceed this angle could lead to challenging play conditions as well as increased risks for bowlers in terms of slipping or losing footing. Meanwhile, slopes that are too steep might not adequately support the green, leading to potential damage from erosion or wear.

While lower angles such as 20 or 30 degrees may seem more manageable, they are below the regulatory maximum and do not fully utilize the guidelines set for optimal bank height and safety. Thus, 35 degrees is the appropriate angle, incorporating considerations for both the playability of the green and the safety of the players.
